Description

Technical Field

[0001] The present invention belongs to the technical field of cable processing, and specifically relates to a cable processing wire drawing device. Background Art

[0002] In the cable production industry, a wire drawing machine is an essential device for production. A wire drawing machine is a mechanical device widely used in industries such as mechanical manufacturing, hardware processing, petrochemical industry, and wire and cable. It is used to draw wire rods or bars, so that the diameter, roundness, internal metallographic structure, surface finish, and straightness of the wire rods or bars meet the raw material processing requirements for the production of standard parts and other metal products.

[0003] Currently, the treatment of wire drawing is basically divided into two types: extrusion by extrusion rollers and through-hole wire drawing. As shown in CN219025424U, metal materials are extruded and drawn through extrusion rollers, and the distance between the extrusion rollers can be adjusted by the rotation of each bidirectional screw, so as to adapt to materials of different diameters. However, the extrusion rollers mainly apply radial pressure, and the materials are subjected to multi-directional compressive stress, making the extrusion rollers more suitable for materials such as alloys. For highly ductile materials such as copper, higher-precision products and higher surface quality can be obtained by through-hole wire drawing. In current through-hole wire drawing forming, if materials of different diameters are to be replaced, it is usually necessary to disassemble and replace the corresponding new wire drawing die in advance, which is rather complicated. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a cable processing wire drawing device to solve the technical problem that different wire drawing dies need to be disassembled and replaced for materials of different diameters in through-hole wire drawing mentioned in the above background art.

[0005] To achieve the foregoing invention purpose, the technical solutions adopted by the present invention include: A cable processing wire drawing device, comprising a frame, a turntable, a rotating assembly, a wire drawing die, a driven assembly, and a transmission assembly; A plurality of the rotating assemblies are provided and rotatably arranged on the frame. The turntable corresponds to each rotating assembly one by one and is fixedly arranged on the rotating assembly; A first wire drawing group is arranged on the turntable. The first wire drawing group includes a plurality of the wire drawing dies. Each wire drawing die is arranged on the turntable coaxially and circumferentially evenly. The apertures of the wire drawing dies on the same turntable increase or decrease evenly in the circumferential direction; the wire drawing dies of each first wire drawing group are opposite in position, and the apertures decrease in sequence along the wire drawing direction; The driven assembly is rotatably arranged on the frame and can drive the rotating assembly to rotate unidirectionally; The transmission assembly is rotatably arranged on the frame and can drive each driven assembly to rotate simultaneously.

[0006] Further, a driving assembly is also provided. The driving assembly is rotatably arranged on the frame, and the driving assembly can drive the transmission assembly to rotate intermittently.

[0007] Further, the rotating assembly includes a connecting frame, a first rotating shaft and a worm gear; the connecting frame is fixedly arranged on the frame, the first rotating shaft is rotatably connected to the connecting frame, the turntable and the worm gear are coaxially fixed on the first rotating shaft, and the driven assembly can drive the worm gear to rotate unidirectionally.

[0008] Further, the driven assembly includes a worm and a first bevel gear. The worm is rotatably connected to the frame and can drive the worm gear to rotate unidirectionally; the first bevel gear is coaxially fixed on the worm, and the transmission assembly can drive the first bevel gear to rotate.

[0009] Further, the transmission assembly includes a transmission mounting seat, a transmission rotating shaft and a second bevel gear; the transmission mounting seat is fixedly arranged on the frame, the transmission rotating shaft is rotatably connected to the transmission mounting seat, the second bevel gear corresponds to the first bevel gear one by one and is coaxially fixed on the transmission rotating shaft, and the first bevel gear meshes with the second bevel gear.

[0010] Further, the driving assembly includes a driving mounting seat, a driving rotating shaft and an incomplete gear; the driving mounting seat is fixedly arranged on the frame, the driving rotating shaft is rotatably arranged on the driving mounting seat, the incomplete gear is coaxially fixed on the driving rotating shaft, a transmission gear is also arranged on the transmission assembly, and the incomplete gear meshes with the transmission gear.

[0011] Further, a driving motor is also arranged on the driving mounting seat, and the driving motor is connected to the driving rotating shaft through a coupling. Further, a mark corresponding to the aperture of the wire drawing die is arranged on the turntable.

[0012] Compared with the prior art, the advantages of the present invention include: In this application, the transmission assembly drives each turntable assembly to rotate simultaneously, adjusts the aperture size of the wire drawing die in the wire drawing direction, so that it can adapt to the new copper material. At the same time, since the apertures of the wire drawing dies in the same wire drawing group change in an arithmetic progression, and the apertures of the opposite wire drawing dies on each first wire drawing group decrease in sequence. Therefore, when the position of the first wire drawing die through which the copper material passes is determined, the subsequent wire drawing dies are also determined. That is, when replacing copper materials with different diameters, only by rotating to determine the first wire drawing die through which it passes, the subsequent wire drawing dies can be determined, without disassembling and replacing each wire drawing die.

[0021] The embodiments of the present invention are intended to introduce and explain the structural composition of a cable processing and wire drawing device and the cooperation relationship between the various component structures. Unless otherwise specified, the dimensions, materials, manufacturing processes, etc. of the various components suitable for the cable processing and wire drawing device in the embodiments of the present invention can be selected according to specific circumstances, and no special limitations and explanations are made here.

[0022] Furthermore, in order to enable the public to have a better understanding of the present invention, some specific details are described in detail in the following detailed description of the present invention. Those skilled in the art can fully understand the present invention without the description of these detail parts.

[0023] Please refer to Figures 1 - 3, this embodiment provides a cable processing wire drawing device, including a frame 1, a turntable 2, a rotating assembly 3, a wire drawing die 41, a driven assembly 5 and a transmission assembly 6; A plurality of rotating assemblies 3 are provided and rotatably arranged on the frame 1. The turntables 2 and the rotating assemblies 3 correspond one by one and are fixedly arranged on the rotating assemblies 3. Specifically, the turntable 2 is a disc and is inserted through the frame 1. The turntable 2 is coaxially fixedly arranged on the rotating assembly 3, and the projections of the turntables 2 in the wire drawing direction overlap.

[0024] A first wire drawing group 4 is arranged on the turntable 2. The first wire drawing group 4 includes a plurality of wire drawing dies 41. Each wire drawing die 41 is arranged coaxially and circumferentially uniformly on the turntable 2, that is, the wire drawing dies 41 are arranged along the circumferential direction of the turntable 2. The wire drawing dies 41 on the same turntable 2 are spaced at the same distance and angle. The apertures of the wire drawing dies 41 on the same turntable 2 increase or decrease uniformly along the circumferential direction; that is, the apertures of the wire drawing dies 41 on the same turntable 2 form an arithmetic progression, and the difference in the apertures of adjacent wire drawing dies 41 is the same. The positions of the wire drawing dies 41 of each first wire drawing group 4 are opposite, and the apertures decrease sequentially along the wire drawing direction; that is, the projections of the wire drawing dies 41 of each first wire drawing group 4 in the wire drawing direction overlap, and the apertures of the opposite wire drawing dies 41 decrease sequentially along the wire drawing direction. Specifically, the apertures of the wire drawing dies 41 of the first wire drawing group 4 whose projections overlap in the wire drawing direction decrease sequentially along the wire drawing direction. Preferably, the difference in the apertures of adjacent wire drawing dies 41 of the first wire drawing group 4 on the same turntable 2 is 1 mm, and the difference in the apertures of the wire drawing dies 41 of each first wire drawing group 4 in the wire drawing direction is 1 mm.

[0025] The driven assembly 5 is rotatably arranged on the frame 1 and can drive the rotating assembly 3 to rotate unidirectionally; that is, the rotating assembly 3 can only rotate when the driven assembly 5 rotates. Specifically, the driven assembly 5 and the rotating assembly 3 correspond one by one. This can avoid the accidental rotation of the turntable 2 during wire drawing.

[0026] The transmission assembly 6 is rotatably arranged on the frame 1 and can drive each driven assembly 5 to rotate simultaneously. The copper material passes through the wire drawing dies 41 with sequentially decreasing apertures on each turntable 2 in a fixed direction to achieve the wire drawing effect. When replacing copper materials with different diameters, rotate the transmission assembly 6 to change the angle of the turntable 2 through the driven assembly 5, so that the aperture of the first wire drawing die 41 through which the copper material passes corresponds to the diameter of the new copper material. Since the apertures of the wire drawing dies 41 of the corresponding first wire drawing group 4 on each turntable 2 decrease sequentially, and at the same time, the apertures of the wire drawing dies 41 of the wire drawing group on the same turntable 2 change arithmetically in sequence. By rotating the first turntable 2 through which the copper wire passes to the required angle, that is, rotating the wire drawing die 41 with an adapted aperture of the first wire drawing group 4 thereon to the wire drawing direction of the copper material, the subsequent wire drawing dies 41 can be in adapted apertures.

[0027] In addition to the above structure, there are also structures such as a wire pay-off device, a drawing mechanism, a wire take-up device, etc. to implement the wire drawing process. Such structures are described in detail in the prior art, so they will not be elaborated here.

[0028] In this application, the driving component 6 drives the rotation of each turntable 2 component at the same time, adjusts the aperture size of the wire drawing die 41 in the wire drawing direction, so that it can adapt to the new copper material. At the same time, since the apertures of the wire drawing dies 41 in the same wire drawing group change in an arithmetic progression, and the apertures of the opposite wire drawing dies 41 on each first wire drawing group 4 decrease in sequence. Therefore, when the position of the first wire drawing die 41 through which the copper material passes is determined, the subsequent wire drawing dies 41 are also determined. That is, when replacing copper materials with different diameters, only by rotating to determine the first wire drawing die 41 through which the copper material passes, the subsequent wire drawing dies 41 can be determined, without disassembling and replacing each wire drawing die 41.

[0029] In other solutions, there is also a driving component 7. The driving component 7 is rotatably arranged on the frame 1, and the driving component 7 can drive the driving component 6 to rotate intermittently. That is, the turntable 2 stops rotating every certain angle. By controlling the angle of each rotation of the driving component 7 to drive the driving component 6, each rotation of the driving component 6 can make the wire drawing die 41 in the first wire drawing group 4 rotate to the position of the previous wire drawing die 41, that is, the rotation angle of the rotating component 3 is the same as the included angle between adjacent wire drawing dies 41 in the first wire drawing group 4. Each rotation of the driving component 6 driven by the driving component 7 corresponds to a new diameter of copper material, so that it is not necessary to adjust the position of the wire drawing die 41 after rotation multiple times, and it can be in place at one time.

[0030] In other solutions, the rotating component 3 includes a connecting frame 31, a first rotating shaft 32 and a worm gear 33; the connecting frame 31 is fixedly arranged on the frame 1, the first rotating shaft 32 is rotatably connected to the connecting frame 31, the turntable 2 and the worm gear 33 are coaxially fixedly arranged on the first rotating shaft 32, and the driven component 5 can drive the worm gear 33 to rotate unidirectionally. It should be understood that the turntable 2 and the first rotating shaft 32 correspond one by one. The connecting frame 31 is preferably arranged on the back of the frame 1 away from the copper wire.

[0031] In other solutions, the driven component 5 includes a worm 51 and a first bevel gear 52. The worm 51 is rotatably connected to the frame 1 and can drive the worm gear 33 to rotate unidirectionally; the first bevel gear 52 is coaxially fixedly arranged on the worm 51, and the driving component 6 can drive the first bevel gear 52 to rotate. That is to say, the worm gear 33 can achieve self-locking after rotation.

[0032] In other solutions, the transmission assembly 6 includes a transmission mounting seat 61, a transmission rotating shaft 62, and a second bevel gear 63; the transmission mounting seat 61 is fixedly arranged on the frame 1, the transmission rotating shaft 62 is rotatably connected to the transmission mounting seat 61, the second bevel gear 63 corresponds to the first bevel gear 52 one by one, and is coaxially fixedly arranged on the transmission rotating shaft 62, and the first bevel gear 52 meshes with the second bevel gear 63. It should be understood that when the turntable 2 rotates, neither the turntable 2 itself nor the wire drawing die 41 thereon interferes with the transmission rotating shaft 62.

[0033] In other solutions, the driving assembly 7 includes a driving mounting seat 71, a driving rotating shaft 72, and an incomplete gear 73; the driving mounting seat 71 is fixedly arranged on the frame 1, the driving rotating shaft 72 is rotatably arranged on the driving mounting seat 71, the incomplete gear 73 is coaxially fixedly arranged on the driving rotating shaft 72, and a transmission gear 64 is further arranged on the transmission assembly 6, and the incomplete gear 73 meshes with the transmission gear 64. It should be understood that the transmission gear 64 is coaxially fixedly arranged on the transmission rotating shaft 62.

[0034] In other solutions, a driving motor 74 is further arranged on the driving mounting seat 71, and the driving motor 74 is connected to the driving rotating shaft 72 through a coupling. Preferably, when the driving motor 74 stops rotating, its output shaft can be clamped. Specifically, when the driving motor 74 is provided, the driving rotating shaft 72 is directly connected to the motor, and when the driving motor 74 is not provided, the driving motor 74 is rotatably connected to the boss on the driving mounting seat 71.

[0035] The above-mentioned cable processing wire drawing device can adapt to wire drawing of materials with different diameters while being disassembled.

[0036] It should be understood that the above embodiments are only used to illustrate the technical concept and characteristics of the present invention, and the purpose is to enable those familiar with this technology to understand the content of the present invention and implement it accordingly. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions or replacements can be made. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
