Description

Technical Field

[0001] This utility model relates to the field of crimping machine technology, specifically a steel-cored aluminum stranded wire crimping machine. Background Technology

[0002] Aluminum-coated steel wire is made by twisting aluminum wire around a steel core. The steel core mainly serves to increase strength, while the aluminum stranded wire mainly serves to transmit electrical energy. Crimping machines are essential tools for power industry to perform conductor splicing during basic line construction and line maintenance.

[0003] According to Chinese Patent Publication No. CN 222168908 U, a crimping machine for building electrical engineering is disclosed. The device includes a base with a support plate at its top. The center of the top surface of the support plate is hollowed out, and a first mold seat is fixedly connected to one side of the top surface of the support plate. The advantages of this invention are: by setting up the support plate, the first and second mold seats externally provide installation positions for the crimping molds; by setting up a first and second push rod, a first guide rod, a second guide rod, a push seat, and a lead screw, rotating the handwheel causes the push seat to drive the second and first push rods to rotate sequentially, thereby pushing the second mold seat through the first guide rod, causing the two crimping molds to move relative to each other, crimping the wires and connectors, completing the crimping operation. Furthermore, it adopts a purely mechanical structure, effectively avoiding oil leakage. The overall structure is simple and easy to promote and use.

[0004] However, the aforementioned existing technologies rely on manual rotation of handwheels for power. When crimping larger wires or performing high-intensity operations, operators need to expend considerable physical strength, which can lead to fatigue over time and affect processing efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a steel-cored aluminum stranded wire crimping machine to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a steel-cored aluminum stranded wire crimping machine, including a workbench, a crimping mechanism is provided on the top of the workbench, and a disassembly mechanism is provided on the outside of the crimping mechanism;

[0007] The pressing mechanism includes a pressing seat and a fixed seat. A lead screw is rotatably connected to the inner side of the pressing seat. A moving block is threadedly connected to the outer side of the lead screw. A push rod is fixedly connected to one end of the moving block. A first servo motor is installed at one end of the lead screw. A mounting seat is fixedly connected to one end of the push rod. A rotating rod is rotatably connected to the inner side of both the mounting seat and the fixed seat. A pressing mold is provided on the outer side of the rotating rod.

[0008] Preferably, both the crimping seat and the fixing seat are fixedly connected to the top of the workbench, and one end of the mounting seat is slidably connected to the top of the workbench.

[0009] Preferably, a second servo motor is installed at one end of the rotating rod, and multiple push rods are provided.

[0010] Preferably, multiple pressing dies are provided, and the multiple pressing dies are arranged in a ring array.

[0011] Preferably, the disassembly mechanism includes a disassembly seat, the disassembly seat has a fixing hole on its outside, a positioning block is engaged inside the fixing hole, and a cylinder is fixedly connected to one end of the positioning block.

[0012] Preferably, multiple disassembly seats are provided, and each of the multiple disassembly seats is fixedly connected to the outside of the rotating rod, with one end of each of the multiple disassembly seats being screwed to one end of a multiple pressing mold.

[0013] Preferably, multiple positioning blocks and cylinders are provided, the multiple positioning blocks are arranged in a rectangular array, and one end of each of the multiple cylinders is fixedly connected to one end of the mounting base and the fixed base, respectively.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0015] First, according to the specifications of the steel-cored aluminum stranded wire to be crimped, this utility model starts the second servo motor outside the fixed base and the mounting base to drive the rotating rod to rotate, thereby driving multiple crimping dies of different specifications outside the rotating rod to rotate, so that the dies at the fixed base and the mounting base are adjusted to match the specifications of the steel-cored aluminum stranded wire. Then, by starting the first servo motor to drive the lead screw to rotate, the moving block moves inside the crimping base, thereby driving the push rod to move, and then pushing the mounting base to slide towards the fixed base. The lead screw makes the crimping pressure more stable until the crimping die at the mounting base moves towards the crimping die at the fixed base, so that the two crimping dies crimp the wire, thus completing the crimping operation, thereby achieving the effect of no manual operation and convenient adjustment of the die specifications.

[0016] Secondly, this utility model facilitates the disassembly and replacement of the pressing mold by connecting the disassembly seat with the pressing mold screw. When the pressing mold is rotated into place, the positioning block is pushed by the starting cylinder, so that the positioning block is locked into the disassembly seat, thereby positioning the disassembly seat and preventing displacement. This prevents the pressing mold from shifting during pressing, thereby improving the pressing accuracy. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides the following technical solution:

[0024] Example 1

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 A steel-cored aluminum stranded wire crimping machine includes a workbench 1, a crimping mechanism 2 is provided on the top of the workbench 1, and a disassembly mechanism 3 is provided on the outside of the crimping mechanism 2.

[0026] The crimping mechanism 2 includes a crimping seat 21 and a fixed seat 27. A lead screw 22 is rotatably connected to the inner side of the crimping seat 21. A moving block 23 is threadedly connected to the outer side of the lead screw 22. A push rod 24 is fixedly connected to one end of the moving block 23. A first servo motor 25 is installed at one end of the lead screw 22. A mounting seat 26 is fixedly connected to one end of the push rod 24. A rotating rod 28 is rotatably connected to the inner side of both the mounting seat 26 and the fixed seat 27. A crimping mold 29 is provided on the outer side of the rotating rod 28.

[0027] Both the crimping seat 21 and the fixing seat 27 are fixedly connected to the top of the worktable 1, and one end of the mounting seat 26 is slidably connected to the top of the worktable 1.

[0028] A second servo motor is installed at one end of the rotating rod 28, and multiple push rods 24 are provided.

[0029] Multiple crimping dies 29 are provided, and the multiple crimping dies 29 are arranged in a ring array.

[0030] Through the above technical solution, based on the specifications of the steel-cored aluminum stranded wire to be crimped, the second servo motor outside the fixed base 27 and the mounting base 26 is activated to drive the rotating rod 28 to rotate, thereby driving multiple crimping dies 29 of different specifications outside the rotating rod 28 to rotate, so that the dies at the fixed base 27 and the mounting base 26 are adjusted to match the specifications of the steel-cored aluminum stranded wire. Then, the first servo motor 25 is activated to drive the lead screw 22 to rotate, thereby causing the moving block 23 to move within the crimping base 21, which in turn drives the push rod 24 to move, thereby pushing the mounting base 26 to slide towards the fixed base 27. The lead screw 22 makes the crimping pressure more stable until the crimping die 29 at the mounting base 26 moves towards the crimping die 29 at the fixed base 27, thereby allowing the two crimping dies 29 to crimp the wire, completing the crimping operation, thus achieving the effect of no manual operation and convenient adjustment of die specifications.

[0031] Example 2

[0032] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 Furthermore, based on Embodiment 1, the following is obtained: the disassembly mechanism 3 includes a disassembly seat 31, the disassembly seat 31 has a fixing hole on its outside, a positioning block 32 is engaged on the inside of the fixing hole, and a cylinder 33 is fixedly connected to one end of the positioning block 32.

[0033] Multiple disassembly seats 31 are provided, and each disassembly seat 31 is fixedly connected to the outside of the rotating rod 28. One end of each disassembly seat 31 is screwed to one end of each pressing mold 29.

[0034] Multiple positioning blocks 32 and cylinders 33 are provided. The multiple positioning blocks 32 are arranged in a rectangular array. One end of the multiple cylinders 33 is fixedly connected to one end of the mounting base 26 and the fixed base 27, respectively.

[0035] Through the above technical solution, the disassembly seat 31 is connected to the pressing mold 29 by screws, which facilitates the disassembly and replacement of the pressing mold 29. When the pressing mold 29 is rotated into place, the starting cylinder 33 pushes the positioning block 32, so that the positioning block 32 is locked into the disassembly seat 31, thereby positioning the disassembly seat 31 and avoiding displacement. This prevents the pressing mold 29 from shifting during pressing, thereby improving the pressing accuracy.
