Description

A kind of group of angle processing unit (plant)

The utility model relates to a kind of machinery processing apparatus, particularly a kind of device that is used for the processing of metal framework group angle.

General corner combining machine all has front top rake, back to press angle etc. that workpiece is clamped on the workbench, by about each cutter that hits of one be mutually certain angle and hit the workpiece that the angle sign indicating number is housed simultaneously, the depression position that makes the angle sign indicating number is by the workpiece left-hand thread and firm combination.But existing corner combining machine is still having following shortcoming aspect power and the transmission.Two groups of employings that has the independently power set source that is used as power bring complex structure like this, and two groups of power also are difficult to synchronously.One group of power set of the usefulness that has source that is used as power, its reaction force is born by frame, is not utilized, and has increased the configuration and the small product size of power.And patent ZL932245293 utilizes the force side of trapezoidal wedging action in the both sides folder palm, make two folder palm move toward one another, though active force and reaction force all can be utilized, but in the course of exerting pressure pressure do not increase progressively gradually (be power gait of march one regularly, the gait of march of hitting cutter is constant, and pressure is also constant) so power also fails to save effectively, and hit the end that screws that cutter directly is contained in the folder palm, make and hit the cutter movement locus and be camber line, still have not enough place in the structure.

The purpose of this utility model is to provide a kind of power configuration more to save, and hits the cutter movement locus linearly, the group angle processing unit (plant) of adjustment, more convenient operation.

The purpose of this utility model is achieved in that selects a kind of oriented structure for use on a substrate, comprise guide type (as slideway and slide block structure) or guiding sleeve type (as guide pillar and shift sleeve structure), single track guiding (as hand hydraulic cutting presser formula structure) or multiple guiding (as four post mould bases structures), configuration one slide block in directed body, it can be moved back and forth in directed body, one end of slide block connects power set, the other end props up strand by a twisted axis and the transmission of both sides and is connected, and make it when static, prop up strand as the equilateral triangularity with two transmissions, diminish gradually up to disappearance at application of force Vee formation shape base angle, two transmissions are propped up strand and are formed straight line, the effect that this process produced is: when power and the speed of service one timing, along with transmission prop up the strand formed triangle become short gradually, it is slack-off gradually that the distal movement speed of strand is propped up in transmission, and active force then increases gradually.Because it is stage in the end that the group angle processes stressed maximum,, act on and play the labour-saving so this structure just in time adapts to the needs of use.The far-end that strand is propped up in transmission is connected with swing arm by connecting rod, about swing arm each one, can swing in opposite directions around two arm shafts, the force transfer end of swing arm top is to the afterbody that hits broach shell, and connector arranged and hit broach shell and be connected, and makes and hits broach shell and swing arm interlock.Hit the broach shell front portion and be equipped with and hit cutter, and under the effect of hitting the directed seat of broach shell, carry out rectilinear motion.Front top rake, back press the angle as fixation workpiece.Power set act on slide block, can select power sources such as manual, motor-driven, pneumatic, hydraulic pressure.And can select the mode of horizontal or vertical arrangement.

The utility model can adopt again slide block is made trapezoidal wedge wide outside and narrow inside aspect transmission of power, directly acts on the force side of swing arm by the inclined-plane of slide block both sides, and slide block is pressed into, and open the force side of swing arm, and force transfer end is swung in opposite directions.Slide block is uncovered, the swing arm homing.Also slide block can be used the screw mandrel transmission, the turn screw mandrel makes slide block reciprocating, props up the strand function by shift fork and transmission that slide block had, and then drives the swing of swing arm.

Fig. 1 is the front view of structure of the present utility model.

Fig. 2 is that the A of structure of the present utility model is to view.

Fig. 3 is that the B of structure of the present utility model is to view.

Below in conjunction with drawings and Examples the utility model is further described: present embodiment has been selected manually to pull operation and has been formed the oriented structure that reaches two guide rail guide types, go up each slideway (2) of one about arrangement at base plate (1), (3) make directed body, slide block (4) can move back and forth between slideway, strand (6) is propped up by a twisted axis (5) and the transmission of both sides in the slide block lower end, (7) connect, the latter is again by left and right sides connecting rod (8), (9) with the swing arm (10) of both sides, (11) force side (12), (13) connect, swing arm (10), (11) there is arm shaft (14) at middle part, (15) swing arm is limited on the base plate (1), makes swing arm (10), (11) can swing in opposite directions.Push up to the afterbody that hits broach shell (18), (19) force transfer end (16) of swing arm (10), (11), (17), by connector (20), (21) and hit broach shell (18), (19) interlock, the front portion of hitting broach shell is equipped with and is hit cutter (22), (23), and under the effect of hitting the directed seat of broach shell (24), (25) moving linearly.The rear portion of hitting broach shell (18), (19) is equipped with to make and is hit cutter (22), (23) flexible adjustment screw (26), (27), front top rake (28) and back press angle (29) as fixation workpiece, wherein the back presses the rear portion at angle (29) that little cam (30) is installed to make the back press angle (29) to advance and retreat and to locate, also can install a hold down gag (31) as required additional and help to flatten workpiece, roller (32), (33) of location usefulness can be set at the edge near workpiece.

Processing front hand grip (34) is held high, slide block (4) is in the extreme higher position, two transmissions are propped up strand (6), (7) lower edge and base plate (1) and are formed triangle, strand (6), (7) are propped up in transmission, connecting rod (8), (9), broach shell (18), (19) are hit in swing arm (10), (11), hit cutter (22), (23) are in retracted state.Pull handle (34) when downwards, under the effect of crank (35), slide block (4) is glided, and strand (6) is propped up in transmission, stretch to both sides (7), drivening rod (8), (9), swing arm (10), (11), hit broach shell (18), (19), hit cutter (22), (23) make move toward one another, two hit cutter (22), (23) under the effect of hitting the directed seat of broach shell (24), (25), hit the workpiece that is fixed, reach the purpose of processing.

The effect that the variation that the utility model has used triangular angles to change formation power brings. Both made relatively to cancelled each other its reaction force of two groups of operating pressures, make again to be worked into Increased required pressure during after-stage. Hitting cutter linearly moves. The accent of broach shell afterbody is hit in utilization Whole screw can be adjusted the length of hitting cutter again easily, and total is perfect, reasonable.
