[0002] Copper alloy wires are widely used in construction, industrial production, motor commutators, spot welders, seam welders, electrodes for butt welders and other fields. The wire straightening and cutting machine is mainly used to perform multiple rounds of extrusion and correction on the fed copper alloy wire to achieve the straightening effect, and then quickly and accurately cut it to obtain a certain length of copper alloy wire.

[0003] When the copper alloy wire cutting machine in the prior art cuts wire, the wire rod extending out of the discharge port is almost in a suspended state, and the extended wire is easily deflected under the action of gravity, resulting in bending of the wire after cutting by the cutter, which cannot meet the straightness requirements.

[0004] Therefore, a cutting device for copper alloy wire processing is needed to solve the problem in the prior art that the discharge end of the cutting machine has no structure to support and straighten the protruding wire, resulting in the center of gravity of the wire protruding from the discharge port shifting in a suspended state, resulting in the wire bending after cutting. Utility Model Content

[0006] To achieve the above purpose, the technical solution adopted by the utility model is: a cutting device for copper alloy wire processing, including a cutting machine body, a support column in the shape of a porch is fixed on one end of the cutting machine body, and a cutter is slidably arranged in the support column, characterized in that: it also includes a supporting strip arranged in front of the cutter, the supporting strip is composed of two V-shaped supporting rods, the V-surfaces of the two supporting rods are arranged oppositely, and a transmission mechanism is arranged on the side away from the two supporting rods;

[0007] The transmission mechanism comprises a push-pull component for moving the support rod away from the wire and a linkage component cooperating with the cutter for providing power to the push-pull component;

[0008] The push-pull component includes a long block vertically arranged beside the support rod, a push-pull block is fixed between the bottom end of the long block and the support rod, a second rack is fixed to the top of the long block, the second rack, the long block and the push-pull block form a Z shape, a gear roller is meshed below the second rack, and the central axis of the gear roller is rotatably connected to the side wall of the support column;

[0009] The linkage component includes a lifting block vertically slidably arranged on the end face of the cutting machine body and a first rack fixed to the top of the lifting block, the first rack is meshed with the gear roller, and the bottom end of the lifting block is provided with a driving component for intermittently lifting the lifting block.

[0010] Preferably, the driving assembly includes a pressure block fixed on the side wall of the cutter, a T-shaped T-rod arranged below the pressure block, and a fixed block arranged below the T-rod, a connecting block is fixed between the top end of the T-rod and the bottom end of the lifting block, the fixed block is fixed to the cutting machine body, the bottom end of the T-rod slides through the fixed block, and a spring is mounted on the rod body of the T-rod located above the fixed block.

[0011] Preferably, a first rectangular through hole is opened on one side of the second rack, a limiting rod is slidably connected in the first rectangular through hole, the end of the limiting rod is fixed on the supporting column, and two limiting blocks are fixedly sleeved on the plate body of the limiting rod, and the two limiting blocks are respectively located on the front and rear sides of the second rack.

[0013] Preferably, a nut is threadedly connected on the rod body of the T-rod located below the fixing block.

[0014] Preferably, a cushion block is provided between the nut and the fixing block, and the cushion block is annularly sleeved on the body of the T-bar.

[0015] Compared with the prior art, the advantages of the utility model are:

[0016] (1) By setting the support rod, when the wire extends from the discharge end of the cutting machine body into the V-shaped surface of the two support rods, when it extends to a specified length, the cutter descends to cut the wire. In this process, the V-shaped surface of the support rod supports and limits the wire, thereby solving the problem in the prior art that the discharge end of the cutting machine has no structure to support and straighten the extended wire, resulting in the center of gravity of the wire extending from the discharge port shifting in a suspended state, resulting in the wire bending after cutting.

[0017] (2) Through the setting of the transmission mechanism, when the cutter cuts the wire, the discharge end of the wire cutting machine body extends into the V-surface of the support rod. When it extends to the specified length, the cutter descends to cut the wire. During this process, the driving component drives the first rack to descend through the lifting block. The descent of the first rack drives the rotation of the gear roller, and the rotation of the gear roller drives the second rack to move toward the side away from the support rod. The movement of the second rack drives the long block and the push-pull block to move synchronously, causing the two support rods to move in opposite directions, and then the V-surfaces of the two support rods are separated. After cutting, the wire falls naturally from the V-surface.

[0018] (3) By setting the nut and the spacer, when it is necessary to cut a larger copper alloy wire, the T-bar can be pressed down to make it go down, and then the nut can be loosened and removed from the end of the T-bar. Then, the spacer is put on the body of the T-bar, and the nut is tightened on the end of the body of the T-bar again. In this way, the height of the T-bar can be lowered by setting the spacer. The decrease in the height of the T-bar drives the lowering of the lifting block and finally causes the V-surfaces of the two support rods to be at a distance, so that the V-surfaces of the two support rods can support the larger wire.

[0026] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0027] Reference Figures 1 to 5 As shown, a cutting device for copper alloy wire processing includes a cutting machine body 1, a support column 2 in the shape of a porch is fixed on one end of the cutting machine body 1, a cutter 3 is slidably arranged in the support column 2, and also includes a supporting strip arranged in front of the cutter 3, the supporting strip is composed of two V-shaped supporting rods 9, the V-shaped surfaces of the two supporting rods 9 are arranged opposite to each other, and a transmission mechanism is arranged on the side away from the two supporting rods 9;

[0028] By setting the support rod 9, when the wire is transported from the cutting machine body 1 to the inner side of the support column 2, the cutter 3 is used to cut the extended wire by intermittent lifting and lowering movement in the support column 2. The wire extends from the inner side of the support column 2 into the V-shaped surface of the two support rods 9. When the wire is extended to a specified length, the cutter 3 descends to cut the wire. In this process, the support and limitation of the V-shaped surface of the support rod 9 is used to solve the problem in the prior art that the discharge end of the cutting machine does not have a structure for supporting and straightening the extended wire, which causes the center of gravity of the wire extending from the discharge port to shift in a suspended state, resulting in bending of the wire after cutting.

[0029] In addition, the cutting machine body 1, the support column 2 and the cutter 3 are the existing DPS-100BS fully automatic cutting machine as a whole. This solution does not describe the specific structure and operation principle of the three in detail. For details, please refer to the existing equipment.

[0030] Further, refer to Figures 1 to 5 As shown, it is worth noting that the transmission mechanism includes a push-pull component for acting on the support rod 9 to move away from the wire and a linkage component that cooperates with the cutter 3 to provide power for the push-pull component;

[0031] The push-pull component includes two long blocks 7 symmetrically arranged on the side away from the two support rods 9, a push-pull block 18 is fixed between the bottom end of the long block 7 and the support rod 9, a second rack 8 is fixed on the side away from the support rod 9 at the top end of the long block 7, a gear roller 15 is meshed below the second rack 8, and the gear roller 15 is rotatably connected to the side wall of the support column 2;

[0032] The linkage components include two lifting blocks 6 slidably arranged on both sides of the discharge end of the cutting machine body 1 and a first rack 5 fixed to the top of the lifting block 6. The two first racks 5 are mirror-distributed and mesh with the two gear rollers 15 one by one. The lifting block 6 is provided with a driving component on the side facing the discharge end.

[0033] The driving assembly includes a pressing block 4 fixed on the side wall of the cutter 3, a T-shaped T-bar 19 arranged below the pressing block 4, and a fixing block 12 arranged below the T-bar 19. A connecting block 11 is fixed between the top end of the T-bar 19 and the bottom end of the lifting block 6. The fixing block 12 is fixed on the cutting machine body 1, and the rod body of the T-bar 19 slides through the fixing block 12.

[0034] Through the setting of the transmission mechanism, when the cutter 3 cuts the wire, one end of the wire cutting machine body 1 extends into the support rod 9V. When it extends to a specified length, the cutter 3 descends to cut the wire. During this process, the driving component passes.

[0035] Through the setting of the driving component, when the cutter 3 descends to cut the wire, one end of the wire cutting machine body 1 extends into the V surface of the support rod 9. When it extends to the specified length, the cutter 3 descends to cut the wire, and the pressure block 4 follows the cutter 3 to descend synchronously. After the cutter 3 cuts the wire, the cutter 3 and the pressure block 4 continue to descend until the pressure block 4 is against the top of the T-bar 19. The pressure block 4 pushes the T-bar 19 to descend along the fixed block 12. During this period, the spring 14 is compressed. The descent of the T-bar 19 drives the lifting block 6 to descend synchronously through the connecting block 11. The lifting block 6 drives the first rack 5 to descend. The descent of the first rack 5 drives the rotation of the gear roller 15, and the rotation of the gear roller 15 drives the second rack 8 to move toward the side away from the support rod 9. The second rack 8 The movement of the second rack 8 drives the long block 7 and the push-pull block 18 to move synchronously, causing the two support rods 9 to move in opposite directions, and then the two support rods 9 are separated in V-plane. After cutting, the wire falls naturally from the V-plane, and when the cutter 3 starts to rise, the T-bar 19 follows the rise under the action of the reverse elastic force of the spring 14, so that the connecting block 11 and the lifting block 6 can be driven to rise synchronously, and the lifting block 6 drives the first rack 5 to rise. The rise of the first rack 5 drives the reversal of the gear roller 15, and the rotation of the gear roller 15 drives the second rack 8 to move toward the side close to the support rod 9. The movement of the second rack 8 drives the long block 7 and the push-pull block 18 to move synchronously, causing the two support rods 9 to move relative to each other, and then the two support rods 9 are closed in V-plane until the two ends of the V-plane are against each other.

[0036] Further, refer to Figures 1 to 5 As shown, it is worth noting that a first rectangular through hole is provided on one side of the second rack 8, a limiting rod 16 is slidably connected in the first rectangular through hole, the end of the limiting rod 16 is fixed on the support column 2, two limiting blocks 17 are fixedly sleeved on the plate body of the limiting rod 16, and the two limiting blocks 17 are respectively located at the front and rear sides of the second rack 8, a second rectangular through hole is provided on the rod body of the lifting block 6, a T-shaped limiting block 10 is slidably arranged in the second rectangular through hole, and the limiting block 10 is fixed on the cutting machine body 1;

[0037] By setting the limiting rod 16 and the limit block 17, the movement trajectory of the second rack 8 on the gear roller 15 can be limited to prevent the second rack 8 from being separated from the gear roller 15. Similarly, by setting the limiting block 10, the movement trajectory of the lifting block 6 can be limited, thereby limiting the movement trajectory of the first rack 5 on one side of the gear roller 15 and preventing the first rack 5 from being separated from the gear roller 15.

[0038] However, from a practical point of view, when it is necessary to cut wires with larger diameters, due to the setting of the support rod 9, when the large-sized wire is extended from the discharge end of the cutting machine body 1, the wire diameter is larger than the inner cavity when the V-shaped surfaces between the two support rods 9 are combined, causing the wire to collide with the support rod 9 when extended, and cannot be cut smoothly;

[0039] In view of this, refer to Figures 1 to 5 As shown, it is worth noting that a nut 13 is threadedly connected to the rod body of the T-shaped rod 19 located below the fixed block 12, and a cushion block 20 is arranged between the nut 13 and the fixed block 12. The cushion block 20 is annularly sleeved on the rod body of the T-shaped rod 19.

[0040] By setting the nut 13 and the spacer block 20, when it is necessary to cut larger copper alloy wires, the T-bar 19 can be pressed down to make it drop, and then the nut 13 can be loosened and removed from the end of the T-bar 19, and then the spacer block 20 can be put on the rod body of the T-bar 19, and the nut 13 can be tightened on the end of the rod body of the T-bar 19 again. In this way, the height of the T-bar 19 can be lowered by the setting of the spacer block 20, and the decrease in the height of the T-bar 19 drives the lifting block 6 to descend and finally causes the two support rods 9V to be separated by a distance, so that the two support rods 9V can support and support larger wires.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
