During cutting, the front feed carriage 500 provides the roller feed carriage 100 with processed tubing. The roller carriage 100 provides the received processed pipe to the clamping device 300. The clamping device 300 clamps the material delivered by the roller feeding frame 100 and can drive the material to rotate during cutting. When the clamping device 300 rotates, the roller feeding frame 100 releases the processed pipe. The laser cutting assembly 200 includes a cutting laser head 201, and the laser head 201 cuts the material clamped on the clamping device 300 when the clamping device 300 drives the material to rotate. The feeding and positioning device 600 is arranged above the roller feeding frame 100, and can be mounted on the roller feeding frame 100 or the front feeding frame 500. The loading positioning device 600 is used for positioning the material which is conveyed from the front material conveying frame 500 and reaches the roller material conveying frame 100 for the first time. A wire length metering device 400 is provided between the roller carriage 100 and the clamping device 300. Of course, in other embodiments, the wire length measuring device 400 may also be disposed on the roller feeding frame 100.
The specific structure of the roller feeding frame 100 having the synchronous moving structure will be described with emphasis. As shown in fig. 4 and 5, the roller feeding frame 100 includes a supporting frame (1, 1 a) and a roller set rotatably disposed on the supporting frame (1, 1 a), the roller set includes a left row of rollers a and a right row of rollers b disposed left and right, and a material space 12 capable of allowing materials to pass through is disposed between the left row of rollers a and the right row of rollers b. The outer circumferential surfaces of the rollers of the left row of rollers a and the right row of rollers b are respectively provided with a left groove 102 and a right groove 112 for clamping materials, and the left groove 102 and the right groove 112 are correspondingly matched left and right. Thus, the centers of the left groove 102 and the right groove 112 have the same height, and the clamping force of the left row of rollers a and the right row of rollers b can act on the same height position of the materials, so that the clamping stability is improved. The support frame includes left support frame 1, right support frame 1a that left and right are separately put, left side row gyro wheel a in the gyro wheel group rotates respectively and sets up on the left support frame 1, right side row gyro wheel b rotates respectively and sets up on the right support frame 1 a. The novel lifting device comprises a chassis 13, wherein the chassis 13 comprises a pair of sliding support rails (2, 2 a), and the left support frame 1 and the right support frame 1a are movably arranged on the pair of sliding support rails (2, 2 a). The device also comprises a pair of positioning columns (4, 4 a), wherein the pair of positioning columns (4, 4 a) are fixedly connected to the front side and the rear side of the underframe 13 and positioned between the left support frame 1 and the right support frame 1 a. The positioning column 4 and the positioning unit 4a have similar structures, and the positioning column 4 is described below as an example. The positioning column 4 comprises a column main body 40 and a mounting arm 41 extending from the column main body 40, wherein a chute 401 extending up and down along a center line O-O between the left row roller a and the right row roller b is arranged on the column main body 40. The positioning column 4 is located outside the space between the left support frame 1 and the right support frame 1a and is mounted on a peripheral coaming 8 which is suggested to be discussed below through the mounting arm 41 so as to be indirectly fixedly connected to the underframe 13, and thus has a fixed position relative to the left support frame 1 and the right support frame 1 a. Of course, in other embodiments, the positioning posts 4 may also be located in the space between the left support frame 1 and the right support frame 1a and directly fixed to the bottom frame 13.
As shown in fig. 4, a pair of synchronizing devices (3, 3 a) are further disposed between the left support frame 1 and the right support frame 1a, and the pair of synchronizing devices (3, 3 a) are disposed at the front and rear sides of the chassis. The synchronization device 3 and the synchronization device 3a have similar structures, and the association structure between the synchronization device 3 and the positioning column 4, the left support frame 1, the right support frame 1a, and the association structure between the synchronization device 3a and the positioning column 4a, the left support frame 1, and the right support frame 1a are similar, and the structure of the synchronization device 3 and the association structure between the synchronization device 3 and the positioning column 4, the left support frame 1, and the right support frame 1a are described below as examples. The synchronous device 3 is herringbone and comprises a first transmission arm (31) and a second transmission arm (32), the head ends (312, 322) of the first transmission arm (31) and the second transmission arm (32) are hinged together through a hinge shaft 33, the hinge shaft 33 is arranged in a sliding groove 401 of the positioning column 4 in a sliding manner and is kept on a central line O-O between the left row roller a and the right row roller b to move up and down, the tail end 311 of the first transmission arm 31 is rotatably arranged on the left support frame 1, and the tail end 321 of the second transmission arm 32 is rotatably arranged on the right support frame 1a. The first and second drive arms (31, 32) are thus associated not only with the positioning column 4 but also with the left support frame 1 or the right support frame 1a, respectively. The sliding device also comprises a moving driver 7 for driving the left support frame 1 and the right support frame 1a to relatively and synchronously approach or fade away, an output shaft of the moving driver 7 is connected to the right support frame 1a, when the moving driver 7 drives the right support frame 1a to move on the sliding support rails (2 and 2 a) and fade away from the left support frame 1, the second transmission arm 32 rotates around the tail end 321 and drives the hinge shaft 33 to slide in the sliding groove 401, and the hinge shaft 33 in sliding pulls the left support frame 1 to synchronously move on the sliding support rails (2 and 2 a) through the first transmission arm 31 and fade away from the right support frame 2. On the contrary, when the moving driver 7 drives the right support frame 1a to move on the sliding support rails (2, 2 a) to approach the left support frame 1, the left support frame 1 can be pulled to synchronously move by means of the positioning column 4 and the synchronizing device 3 to approach the right support frame 1a. Of course, in other embodiments, a correlation structure different from the above-mentioned one may be used between the synchronization device 3a and the positioning column 4a, the left support frame 1, and the right support frame 1a, for example, a second correlation structure to be discussed below may be used; or only one positioning column and one synchronizing device are arranged.
According to the technical scheme, the following steps are found: through the cooperation of reference column (4, 4 a) with synchronizer (3, 3 a), let left branch frame 1, right branch frame 1a are confirmed left side and are listed as under the circumstances that center line O-O's between gyro wheel a and the right side keeps unchanged the position of gyro wheel b synchronous and are close to or fade away to can adapt to the material of different size specifications, enlarge the application scope of gyro wheel pay-off frame, and can exert even, moderate clamping force from the left and right sides of material respectively, be favorable to improving push speed. In addition, since a pair of positioning columns (4, 4 a) and a pair of synchronizing devices (3, 3 a) are arranged, the pair of positioning columns (4, 4 a) and the pair of synchronizing devices (3, 3 a) can synchronously control the movement of the left support frame 1 and the right support frame 1a from front and back sides, the stability of the movement of the left support frame 1 and the right support frame 1a is improved, and the clamping force of the roller on the material can be further homogenized. The moving driver 7 not only can drive the right supporting frame 1a to move, but also can apply driving force to the left supporting frame 1 from front and rear sides simultaneously through the right supporting frame 1a and the pair of the synchronizing devices (3, 3 a) by means of the pair of the positioning columns (4, 4 a), and even clamping force can still be applied between the left row of rollers a and the right row of rollers b when the left supporting frame 1 and the right supporting frame 1a are loaded by a large number of rollers.
Besides, the following association structures can be selected between the synchronization device and the positioning column, the left support frame 1, and the right support frame 1 a:
In a second related structure, as shown in fig. 6, the synchronization device 3 "is in a cross shape, the middle positions of the first and second transmission arms (31", 32 ") are hinged together by a hinge shaft 33", the hinge shaft 33 "is fixedly arranged on the positioning column 4" and positioned on a central line O-O between the left row roller a and the right row roller b, and the head ends (311 ", 321") of the first and second transmission arms (31 ", 32") are respectively and slidably arranged on the sliding groove 14 of the left support frame 1, and the tail ends (312 ", 322") of the first and second transmission arms (31 ", 32") are respectively and slidably arranged on the sliding groove 14a of the right support frame 1 a. So that when the left support frame 1 is driven to move on the sliding support rails (2, 2 a) so as to fade away from the right support frame 1a, the head ends (311 ', 321') of the first and second transmission arms respectively rotate around the hinge shaft 33 'and slide toward each other so that the first and second transmission arms are respectively moved toward each other the tail ends of the second transmission arms (31', 32 ') are simultaneously rotated around the hinge shafts 33' and are slid toward each other, thereby pulling the right support frame 1a to move synchronously on the sliding support rails (2, 2 a) and to fade away from the left support frame 1, and vice versa.
As shown in fig. 7, in the third related structure, the head end 312 'of the first driving arm 31' is rotatably disposed on the positioning post 4 'through the left rotating shaft 313', the tail end 311 'of the first driving arm 31 is slidably disposed on the chute 14 of the left support frame 1, the head end 322' of the second driving arm 32 is rotatably disposed on the positioning post 4 'through the right rotating shaft 323', the tail end 321 'of the second driving arm 32' is slidably disposed on the chute 14a of the right support frame 1a, and driving teeth are disposed between the head end 312 'of the first driving arm 31' and the head end 322 'of the second driving arm 32', and the left rotating shaft 313 'and the right rotating shaft 323' are symmetrically disposed on left and right sides of the center line O-O between the left row roller a and the right row roller b. Thus, when the left support frame 1 is driven to move on the sliding support rails (2, 2 a) so as to fade away from the right support frame 1a, the first transmission arm 31 'rotates around the left rotating shaft 313' and simultaneously the second transmission arm 32 'is driven to rotate around the right rotating shaft 323' through transmission teeth so as to pull the right support frame 1a to move on the sliding support rails (2, 2 a) so as to fade away from the left support frame 1, and vice versa.
A fourth association structure, which is relatively simple, can be understood with reference to fig. 4.
