Description

Technical Field

[0001] The utility model relates to the technical field of wire drawing machines, in particular to a copper wire drawing machine. Background Art

[0002] A copper wire drawing machine stretches and extends copper wire to shorten the thickness of the original copper wire through stretching. Existing wire drawing machines generally consist of a wire pay-off stand, a wire drawing die, a coiling device, and a driving structure. The coiling device drives the copper wire to pass through the wire drawing die, and the thickness of the copper wire is drawn into a specific specification through the specification of the die.

[0003] However, existing copper wire drawing machines often install a set of wire drawing dies (drawing columns) on a horizontal mounting frame for wire drawing of copper wire. When it is necessary to change to other specifications, the drawing columns need to be disassembled before replacement, which is rather troublesome and cannot achieve quick replacement. Secondly, in the existing technology, multiple sets of wire drawing holes are formed on the surface of the drawing columns. Although this method is rather ingenious, it is not convenient in actual use and requires rotation and clamping. The most important thing is that this structure reduces the equipment that can draw six copper wires simultaneously to three, greatly reducing the wire drawing efficiency. The most important thing is that it is large in size and not convenient for use and maintenance.

[0004] Therefore, in order to achieve quick replacement of the drawing columns without affecting the number of wires drawn, a copper wire drawing machine is hereby proposed to solve the above technical problems. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a copper wire drawing machine, which solves the problem that it is inconvenient to replace the drawing columns when it is necessary to change the wire drawing specifications in existing wire drawing machines.

[0006] To achieve the above object, the utility model provides the following technical solution: A copper wire drawing machine includes a wire drawing machine main frame, a driving structure, and a transmission structure. A side mounting frame is installed on the right side of the wire drawing machine main frame. The driving structure is installed on the rear side of the side mounting frame, and the transmission structure is installed on the front side of the side mounting frame. The driving structure is connected to the transmission structure. A wire drawing module for drawing copper wire and facilitating the replacement of wire drawing specifications is installed on the side mounting frame. The wire drawing module includes a wire drawing die body and a clamping member. The wire drawing die body includes a horizontal mounting frame installed on the front side of the side mounting frame. Multiple horizontal openings are formed on the upper surface of the horizontal mounting frame. Chamfers are formed at the horizontal openings, and an opening is also formed on the upper end surface of the horizontal mounting frame. The clamping member is installed on the left side and the right side of the horizontal mounting frame. A wire drawing die is arranged in the opening. Mounting holes are formed on the surface of the wire drawing die, and drawing columns are arranged in the mounting holes. The clamping member is in contact with the surface of the wire drawing die. The wire drawing die is arranged in two rows on the horizontal mounting frame and is arranged staggeredly.

[0007] Through the above technical solution, further, a telescopic spring is further provided in the mounting hole, and a gasket is further mounted on the left side surface of the telescopic spring, and the gasket is in contact with the surface of the wire drawing column.

[0008] Further, the clamping member includes a clamping bolt and a circular clamping piece. The clamping bolt is mounted on the side surface of the transverse mounting frame through a thread, and a circular clamping piece is provided at the right end of the transverse mounting frame. The circular clamping piece is in contact with the surface of the wire drawing die.

[0009] As a preferred technical solution, the driving structure includes a servo reduction motor, and the servo reduction motor is mounted on the rear end surface of the side mounting frame. The output end of the servo reduction motor penetrates through the side mounting frame and is connected to the transmission structure.

[0010] Further, the transmission structure includes a left tower pulley, a right tower pulley, a winding pulley, a main transmission pulley, a transmission pulley, and a transmission belt.

[0012] Beneficial effects:

[0013] 1. In this solution, the wire drawing column is mainly installed in the wire drawing die, so that multiple groups of wire drawing columns can be installed in a group of wire drawing dies. Then, the wire drawing column is inserted into the opening. When it needs to be changed, only the position of the wire drawing die in the opening needs to be pulled, and then the clamping bolt is rotated to make the circular clamping piece clamp the wire drawing die.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment

[0025] Please refer to Figure 1-8, the present utility model provides the following technical solutions: A copper wire drawing machine includes a drawing machine main frame 1, a driving structure, and a transmission structure. A side mounting frame 4 is installed on the right side of the drawing machine main frame 1. The driving structure is installed on the rear side of the side mounting frame 4, and the transmission structure is installed on the front side of the side mounting frame 4. The driving structure is connected to the transmission structure. A wire drawing module for drawing copper wire and facilitating the replacement of the wire drawing specification is installed on the side mounting frame 4. The wire drawing module includes a wire drawing die body and a clamping member. The wire drawing die body includes a horizontal mounting frame 3 installed on the front side of the side mounting frame 4. Multiple horizontal openings are provided on the upper surface of the horizontal mounting frame 3, and rounded corners are provided at the horizontal openings. In this way, when the copper wire passes through the horizontal openings, in the case where it may come into contact with the opening edge, the rounded corner design can avoid the problem of friction between the copper wire and the edge, thereby protecting the quality of the copper wire. Moreover, an opening 13 is also provided on the upper end surface of the horizontal mounting frame 3. The clamping member is installed on the left side and the right side of the horizontal mounting frame 3. A wire drawing die 8 is provided in the opening 13. Mounting holes 11 are provided on the surface of the wire drawing die 8, and wire drawing columns 10 are provided in the mounting holes 11. The clamping member is in contact with the surface of the wire drawing die 8. The wire drawing die 8 is arranged in two rows on the horizontal mounting frame 3 and is staggered.

[0026] In this implementation, the specific working principle is as follows: In this wire drawing machine, multiple wire drawing columns 10 are mainly placed into the mounting holes 11 on the surface of the wire drawing die 8, then the wire drawing die film 8 is inserted into the opening 13, and then the wire drawing die film 8 is clamped and fixed by the clamping member. In this way, the replacement of wire drawing columns 10 of different specifications can be realized quickly and conveniently. Thus, through such a setting, the problem that the existing wire drawing machine cannot conveniently replace the wire drawing column when the wire drawing specification needs to be changed is solved. During operation, the driving structure mainly drives the transmission structure to rotate, and then drives the copper wire to perform wire drawing operations in the wire drawing die body.

[0027] According to the above, in order to provide a buffering effect during the wire drawing operation of the wire drawing column 10 and thus improve the service life of the wire drawing column 10, specifically, refer to Figure 5 It can be seen that a telescopic spring 12 is also provided in the mounting hole 11. A gasket is also installed on the left side surface of the telescopic spring 12, and the gasket is in contact with the surface of the wire drawing column 10. In this way, when the copper wire passes through the wire drawing hole on the surface of the wire drawing column 10 due to a large pulling force, the wire drawing column 10 is pushed to the right side. Through the action of the telescopic spring 12, the thrust of the wire drawing column 10 can be effectively slowed down, thereby preventing damage to the wire drawing column 10 and the mounting hole 11 due to extrusion, and thus extending the service life of the wire drawing column 10.

[0028] In order to clamp the wire drawing die 8, specifically, refer to Figure 4 , Figure 5 , Figure 8It can be seen that the clamping member includes a clamping bolt 9 and a circular clamping piece 14. The clamping bolt 9 is installed on the side surface of the transverse mounting frame 3 by means of a thread. A circular clamping piece 14 is provided at the right end of the transverse mounting frame 3. The circular clamping piece 14 is in contact with the surface of the wire drawing die 8. By rotating the clamping bolt 9 and through the threaded fit between the clamping bolt 14 and the transverse mounting frame 3, when the clamping bolt 9 is rotated clockwise, the circular clamping piece 14 is driven to move inward, thereby clamping and fixing the wire drawing die 8.

[0029] Among them, for the specific driving structure, reference can be made to Figure 2 It can be seen that the driving structure includes a servo reduction motor 5. The servo reduction motor 5 is installed on the rear end face of the side mounting frame 4. The output end of the servo reduction motor 5 penetrates through the side mounting frame 4 and is connected to the transmission structure. The servo reduction motor 5 drives the connection of the transmission structure.

[0030] According to the above, for how the servo reduction motor 5 drives the connection of the transmission structure, reference can be made to Figure 2 It can be seen that the transmission structure includes a left tower pulley 2, a right tower pulley 7, a winding pulley 6, a main transmission pulley 15, a transmission pulley 16, and a transmission belt 17. The left tower pulley 2 and the right tower pulley 7 are both installed on the front side surface of the side mounting frame 4. The rear end of the right tower pulley 7 is connected to the output end of the servo reduction motor 5, and a main transmission pulley 15 is installed on the surface of the rear end of the right tower pulley 7. A winding pulley 6 is installed on the front right end face of the side mounting frame 4. A transmission pulley 16 is installed at the rear end of the winding pulley 6. The transmission pulley 16 and the main transmission pulley 15 form a transmission through the transmission belt 17. First, the servo reduction motor 5 drives the right tower pulley 7 to rotate, and then the rotation of the winding pulley 6 is realized through the action of the main transmission pulley 15 and the transmission pulley 16.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
