In mode before, on axle, to implement to be used for the keyway processing of sunk key and the processing of the screwed hole that is used for fixing, therefore, sometimes with groove inner corners or screwed hole be that starting point cracks, crack etc.
In the present invention, as mentioned above, the diameter that can make bolster 7 is than significantly reducing before.Therefore, be formed on the machining tolerance of diameter etc. in the hole 5 of forming rolls 2 central portions,,, just can guarantee the sufficient product quality of roller formed products as long as note bolster 7, be formed on the roundness in the hole 5 of forming rolls 2 central portions even set greatlyyer than before.
In addition, in the present invention, adopt Fig. 2, Fig. 3, the illustrated combination of Figure 13, Figure 14, so, when changing forming rolls, bolster 7 is unloaded at every turn.Therefore, when changing forming rolls, have under the situation of problems such as damage, can change bolster 7 at once at bolster 7.
As Figure 15～shown in Figure 17, in mode before, universal joint and rotary driving force power shaft 106 are fastening by support 103.Before, with its separation, replacing, need the considerable time.
Compare with production process, the manufacturing cost of the rotary driving force power shaft 106 that adopts in Figure 15～mode before shown in Figure 17, the production process of the bolster 7 that adopts in Fig. 2,3,13, the 14 illustrated combinations of the present invention, manufacturing cost reduce a lot, and expense is lower.
In addition, in Figure 13, embodiment of the present invention shown in Figure 14, support forming rolls 2 with central protrusion 1a that is formed on turntable 1 central authorities and the central protrusion 7a that is formed on bolster 7 front ends, this forming rolls 2 with above-mentioned projection 1a, 7a face in opposite directions on formed recess 5a, 5b respectively.Therefore, needn't image pattern 2, embodiment shown in Figure 3 forms the hole 5 of hole formed therethrough roller 2 like that.That is, in Figure 13,14, in the top and bottom of forming rolls 2, if exist recess 5a, the 5b that is supported by central protrusion 1a, central protrusion 7a, then forming rolls 2 is being supported by central protrusion 1a and central protrusion 7a and is rotating.Therefore, as long as note to form the shape in the hole, groove etc. of recess 5a, 5b, just can guarantee the sufficient product quality of roller formed products.In addition, and compare before, can be reduced to the local forming rolls of making significantly.
Under state shown in Figure 1, take off the axle collar 30, take off bolster 7 from turntable 1 and forming rolls 2 again from bolster 7, perhaps bolster 7 is lifted to the axle collar 30 upside end face top, take off the axle collar 30.Then, the forming rolls 2 that becomes state shown in Fig. 2 downside is taken off from turntable 1, like this, can unload forming rolls 2 simply, be replaced by other forming rolls.
Similarly, the bolster 7 that front end is had central protrusion 7a is mentioned toward the top in the embodiment of Figure 13, Figure 14, and forming rolls 2 becomes open state.Under this state, if forming rolls 2 is mentioned slightly toward the top, then be disengaged with combining also of turntable 1, become state fully freely.Like this, can unload forming rolls 2 simply, be replaced with other forming rolls.
Especially, in Figure 13, embodiment shown in Figure 14, needn't image pattern 2, embodiment shown in Figure 3 inserts bolster 7 in the hole 5 of hole formed therethrough rollers 2 central authorities like that, just can support forming rolls 2, makes its rotation.Therefore, even unload forming rolls 2, when being replaced with other forming rolls, also will from the hole 5 of forming rolls 2 central authorities, not extract by bolster 7.Therefore, can significantly shorten the lay day of roller.
According to Fig. 1～embodiment shown in Figure 3, bolster 7 is gone up in the figure on the upside end face that side direction is lifted to the axle collar 30, bolster 7 is extracted, the axle collar 30 is also taken out,, just can simply forming rolls 2 be replaced with other forming rolls as long as forming rolls 2 is mentioned slightly toward upside.
In addition, can unload forming rolls 2 simply similarly in Figure 13, the embodiment shown in Figure 14, be replaced with other forming rolls.
As Figure 15～shown in Figure 17, in roll forming device before, on each roller support 103, be equipped with gear-box 105 respectively.Rotary driving force power shaft 106 is 101,102 extensions from each gear-box 105 towards forming rolls, are encased in the hole of each forming rolls 101,102 central authorities.Each rotary driving force power shaft 106 has the input side holding section in its cylinder sides.The inwall in each forming rolls 101,102 hole in the central has roller side holding section.By the engaging between input side holding section and the roller side holding section, the rotary driving force from motor 104 is passed to each forming rolls 101,102.Forming rolls in this roll forming device before, when the replacing of forming rolls, must expensive time and labor.Especially, will be (among Figure 16 the very heavy big support 103 of supporting rotary driving force power shaft 106, support 103 away from fixed teeth roller box 105 1 sides) break away to come from forming machine body base and be replaced with the shape roller, so, the expensive time and labor of having to.
In the present invention, embodiment as shown in Figure 1 is such, and the turntable 1 as forming rolls 2 being imported the revolving force transmission mechanism of revolving forces is driven by servo motor (figure does not show).By universal joint 8 rotation is passed to turntable 1 from servo motor.
Embodiment uses universal joint 8 can easily carry out loading and unloading between servo motor and the turntable 1 so as shown.In addition, can freely select the position of the turntable 1 of chimeric bolster 7, forming rolls 2.
Fig. 4 is the front elevation that is being equipped with pair of right and left forming rolls 2, is constituting the state of the shaped bracket in the roll forming device.Shaped bracket is made of pedestal 10, and this pedestal 10 is being supported by pin 11,11.In addition, forming rolls 2 is accepted the rotation transmission by universal joint 8, turntable 1 from being configured in ground servo motor 9.Pair of right and left forming rolls 2,2 among Fig. 4 has Fig. 1～Fig. 3 or Figure 13, combination illustrated in fig. 14.
Fig. 5 is being equipped with pair of right and left forming rolls 2,2 and is being equipped with a pair of dummy roll 12,12 up and down orthogonally with this pair of right and left forming rolls 2,2, constitutes the front elevation of the state of the shaped bracket in the roll forming device.Pair of right and left forming rolls 2,2 among Fig. 5 has Fig. 1～Fig. 3 or Figure 13, combination illustrated in fig. 14.
When using universal joint 8, be configured in ground servo motor 9 conjugate sides as fixing point, universal joint 8 is moved shown in arrow 50,51.Like this, the position of the turntable 1 of chimeric bolster 7, forming rolls 2 is moved arbitrarily towards the direction shown in the arrow 52,53.Like this, can freely select the position of the turntable 1 of chimeric bolster 7, forming rolls 2.
In addition, be not limited to Fig. 4, embodiment shown in Figure 5, can combine the forming rolls 2 of Fig. 1～Fig. 3 of arbitrary number or Figure 13, Figure 14 explanation and dummy roll 12 and constitute shaped bracket in the roll forming device.
According to the present invention, as mentioned above, the side that turntable 1 in forming rolls 2 extends towards forming rolls 2, formed roller side snap fastener (groove 4), front at turntable 1 towards forming rolls 2 extensions, formed input side snap fastener (key 3), this roller side snap fastener and input side snap fastener engage mutually.Thus, can import revolving forces to forming rolls 2 from the turntable 1 of input rotary driving force.
Only play the be shaped effect of load of supporting under arbitrary situation of bolster 7 in Fig. 2, embodiment shown in Figure 3, Figure 13, embodiment shown in Figure 14.Therefore, as previously mentioned, can carry out the replacing of roller simply by the utmost point.
In roll forming device before, as shown in figure 16, be installed in a plurality of forming rolls 101,102 on the multistage support 103 of tandem configuration, drive simultaneously by a motor 104 usually.That is, the forming rolls 101,102 that is installed on the multistage support 103 all rotates with identical rotary speed.In addition, each forming rolls the 101, the 102nd is processed the workpiece that metal tube is such, it is desirable to, on one side component shaping is pushed workpiece towards direct of travel on one side.But at the upstream side of the multistage support 103 of tandem configuration, even pushing force has very little variation, the forming speed of the support in downstream just is unable to catch up with, and the result plays braking action sometimes to the pushing force of upstream side.The rotation of gear-box 105 is transmitted boundary at this, and because of different former of roller diameter, roll profile (shape) thereby when producing extreme peripheral speed difference, the consumption of the gear in the gear-box 105 is very big, and maintenance cycle shortens.That is, must take into full account whole roller diameters.Therefore, in mode before, cause the waste of shaping energy.
In order to address this problem, once attempted mode shown in Figure 17 before, that is, servo motor 110 (also can be common motor) is installed respectively on each, by universal joint rotary driving force is passed to forming rolls.In this mode, universal joint is that the center can be moved towards arrow 120,121 directions with the stiff end, like this, forming rolls is moved towards arrow 123,124 directions, can regulate the interval of pair of rolls.But, when giving rotary driving force with 110 pairs of each forming rolls of servo motor like this, structure is maximized.For example, in embodiment shown in Figure 17, the total height of 2 servo motor bodies is bigger than support height up and down, for centring, has to stand base and CD-ROM drive motor pedestal are cut apart, and is again that each pedestal is fastening powerfully.In addition, because the relation of mechanical arrangement must enlarge between each support, the size dimension of machinery (pedestal) is extended in the shaping direction.
According to the present invention, as shown in Figure 4, forming rolls 2 and accept turntable 1 that rotation transmits by universal joint 8 from servo motor 9 between, engage by roller side snap fastener (groove 4) and input side snap fastener (key 3).In addition, roller side snap fastener (groove 4) is formed on the side that the turntable 1 in the forming rolls 2 extends towards forming rolls 2.Input side snap fastener (key 3) is formed on the front towards forming rolls 2 extensions of turntable 1.With such combination, constituted structure to forming rolls 2 input revolving forces.Therefore, promptly use servo motor to give rotary driving force, structure is maximized each forming rolls 2.
In roll forming device, because driven roller applies centripetal force to the such workpiece of metal tube, so, bigger than dummy roll.In Figure 15～roll forming device before shown in Figure 17, because driven roller is configured in the support longitudinal direction, so, increase upward.And among the present invention, as Fig. 4, shown in Figure 5, configuration driven roller laterally is so the mechanical dimension of above-below direction is lower than before.
That is,, can not make structure give rotary driving force with servo motor to each forming rolls 2,2 according to the present invention with maximizing.
In addition, give rotary driving force with servo motor, the rotation number in the time of can grasping shaping, rotary speed, torque etc. can realize the processing under the best molding condition.

Fig. 6, Fig. 7 illustrate the supporting device of roller of the present invention and roller.Special instruction can be provided in the dummy roll supporting member 20 in the roll forming device of the present invention.
As Fig. 6, shown in Figure 7, dummy roll 22 is with known dummy roll is identical before, and swivel bearing axle 23 is being supported by the support 21 of dummy roll supporting member 20.
In dummy roll before, adopt Fig. 8, supporting device shown in Figure 9.
As shown in Figure 8, when workpiece 25 is advanced towards arrow W direction, on support 21, acting on direction shown in vector S, the T to make a concerted effort be power F.Therefore, part shown in the mark 20b during as fixation side, roller 22 is not stayed the position of hope and is expanded towards the opposition side of Forming Workpiece 25 and to open, thereby has problems.On the other hand, can make roller 22 stay the position of hope during as fixation side part shown in the mark 20a.But direction is moving slightly up in Fig. 8.At this moment, machinery integral becomes very big.
As shown in Figure 9, similarly can obtain same effect to part shown in the mark 20a during as fixation side with Fig. 8.But, when making such shape, though part shown in the mark 20b as fixation side, support 21 itself also sinks to (automatically tight strand) towards the direction of workpiece 25.In order to realize this point, must add the length H of long vector T direction.Perhaps, if insufficient consideration intensity then may not stayed the position of hope, perhaps may destroy.
Like this, when workpiece 25 has entered between a pair of dummy roll 22 in opposite directions, do not expand out, adopt supporting device shown in Figure 9 before in order to make the interval between the dummy roll 22 in opposite directions.This mechanism compares with mechanism shown in Figure 8, has strengthened the interval shown in the label L among Fig. 9, like this, utilizes moment, suppresses the power of vector T direction, reduces change.
Under this situation shown in Figure 9, have to strengthen shape, the structure of support 21.For example, with respect to the direct of travel W of workpiece 25, must become the support structure of 1.5～2 times of sizes that are configured in the shaped bracket before or after the support with dummy roll 22.
