Description

Technical Field

[0001] This utility model belongs to the technical field of cold heading machines, and specifically relates to a wire feeding device for cold heading machines. Background Technology

[0002] A cold heading machine is a stamping machine used in mechanical manufacturing. It shapes raw materials into the required shape (generally, into "steps") without altering them (mainly by softening or hardening them).

[0003] Currently, most cold heading machine wire feeding devices support the winding spool with the wire wound by a spool bracket and use a reciprocating stabilizing shaft. When the wire passes between the two stabilizing shafts, the surface of the wire is not easily worn.

However, because the swing amplitude of the stabilizing shaft cannot be adjusted according to the swing amplitude of different wires, the adaptability of the feeding device is low. At the same time, because the position of the spool bracket is fixed, the spool bracket can only support the winding spool of a specified length, which also results in low adaptability of the feeding device.

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] like Figures 1 to 12 As shown, a wire feeding device for a cold heading machine includes a base plate 1. A first electric push rod 2 is fixedly connected to the upper surface of the base plate 1. A stabilizing box 3 is connected to the upper surface of the first electric push rod 2. Circular holes 4 are provided on both the front and rear sides of the stabilizing box 3. Elastic brackets 5 are fixedly connected to the inner wall of the circular holes 4 and the back of the stabilizing box 3. A first rotating bearing 6 is fixedly connected to the surface of the elastic bracket 5. A stabilizing shaft 7 is fixedly connected to the outer ring of the first rotating bearing 6. A translation mechanism 8 is fixedly connected to the back of the stabilizing box 3. A motor base 9 is fixedly connected to the front of the translation mechanism 8. A drive motor 10 is fixedly connected to the front of the motor base 9. A rotating shaft 11 is fixedly connected to the output end of the drive motor 10. An elliptical plate 12 is fixedly connected to the surface of the rotating shaft 11.

[0034] The elastic support 5 includes a first cylinder 51, a first linear bearing 52, a first vertical plate 53, a second vertical plate 54, and a spring 55. The surface of the first cylinder 51 is in contact with the inner wall of the first linear bearing 52, the surface of the first linear bearing 52 is fixedly connected to the inner wall of the circular hole 4, the front of the first cylinder 51 is fixedly connected to the back of the first vertical plate 53, the back of the first cylinder 51 is fixedly connected to the front of the second vertical plate 54, the front and rear sides of the spring 55 are fixedly connected to the front of the second vertical plate 54 and the back of the stabilizing box 3, respectively, and the surface of the first cylinder 51 is fixedly connected to the inner ring of the first rotating bearing 6.

[0035] The translation mechanism 8 includes a connecting column 81, a third vertical plate 82, a first slide cylinder 83, a fourth vertical plate 84, and a second electric push rod 85. The front and rear ends of the connecting column 81 are fixedly connected to the front of the third vertical plate 82 and the back of the stabilizing box 3, respectively. The front and rear ends of the second electric push rod 85 are fixedly connected to the front of the third vertical plate 82 and the back of the fourth vertical plate 84, respectively. The left and right sides of the fourth vertical plate 84 are fixedly connected to the sides of the first slide cylinder 83. The inner wall of the first slide cylinder 83 is in contact with the surface of the connecting column 81. The front of the fourth vertical plate 84 is fixedly connected to the back of the motor base 9.

[0036] It should be noted that the first cylinder 51 is connected to the stabilizing shaft 7 by the first rotary bearing 6, and the stabilizing shaft 7 can rotate freely on the first cylinder 51. The spring 55 pushes on the second vertical plate 54, so that the first vertical plate 53 can be in close contact with the stabilizing box 3 when the second vertical plate 54 is not pushed by the elliptical plate 12. The first linear bearing 52 makes the first cylinder 51 move only back and forth, and the first linear bearing 52 makes the movement of the first cylinder 51 smoother.

[0037] When the drive motor 10 drives the elliptical plate 12 to rotate, the elliptical plate 12 first contacts the second vertical plate 54. Then, through the pushing force of the rotating elliptical plate 12 and the spring 55 on the second vertical plate 54, the second vertical plate 54 moves back and forth. At the same time, by changing the distance between the rotating shaft 11 and the stabilizing box 3, the amplitude of the back and forth movement of the second vertical plate 54 can be changed.

[0038] The cooperation between the first slide cylinder 83 and the connecting column 81 allows the fourth vertical plate 84 to move only back and forth. At the same time, the second electric push rod 85 can control the back and forth movement of the fourth vertical plate 84, and by moving the fourth vertical plate 84, the distance between the rotating shaft 11 and the stabilizing box 3 is changed.

[0039] like Figures 1 to 8 As shown, a cylinder 13 is fixedly connected to the back of the stabilizing box 3, a second linear bearing 14 is fixedly connected to the inner wall of the cylinder 13, a second cylinder 15 is fitted to the inner wall of the second linear bearing 14, and the back of the second cylinder 15 is fixedly connected to the front of the second vertical plate 54.

[0040] It should be noted that by cooperating with the cylinder 13, the second linear bearing 14, and the second cylinder 15, the force on the connection between the second vertical plate 54 and the first cylinder 51 is reduced when the elliptical plate 12 pushes the second vertical plate 54, thereby making it less likely for the connection between the second vertical plate 54 and the first cylinder 51 to crack.

[0041] like Figures 1 to 11 As shown, a second rotating bearing 16 is fixedly connected to the surface of the rotating shaft 11, and a reinforcing block 17 is fixedly connected to the outer ring of the second rotating bearing 16. The back of the reinforcing block 17 is fixedly connected to the front of the fourth vertical plate 84.

[0042] It should be noted that the cooperation between the second rotating bearing 16 and the reinforcing block 17 can limit the rotation shaft 11 and prevent the connection between the rotation shaft 11 and the drive motor 10 from cracking when the elliptical plate 12 pushes the second vertical plate 54.

[0043] like Figures 1 to 14 As shown, a bobbin bracket 18 is attached to the upper surface of the base plate 1. A first groove 19 is formed inside the bobbin bracket 18. A U-shaped plate 20 is attached to the inner wall of the first groove 19. The bottom of the U-shaped plate 20 is fixedly connected to the upper surface of the base plate 1. A first connecting block 21 is fixedly connected to both the left and right sides of the inner wall of the first groove 19. The upper surface of the first connecting block 21 is attached to the bottom of the U-shaped plate 20. A second connecting block 22 is fixedly connected to the inner wall of the U-shaped plate 20. A third electric push rod 23 is fixedly connected to both the front and rear sides of the second connecting block 22 and the surface of the first connecting block 21. A second groove 24 is formed on the upper surface of the bobbin bracket 18. A winding bobbin 25 is attached to the inner wall of the second groove 24.

[0044] It should be noted that, through the cooperation of the U-shaped plate 20, the first connecting column 81, the second connecting block 22 and the third electric push rod 23, the first electric push rod 2 can control the spool support 18 to move back and forth, and by adjusting the position of the spool support 18, the spool support 18 can support a winding spool 25 of any diameter. At the same time, the winding spool 25 is located on the right side of the stabilizing box 3.

[0045] The working principle of this utility model is as follows: First, the winding shaft 25 with the wire wound is placed in the second groove 24 and supported by the winding shaft bracket 18. Then, the wire is passed between the upper and lower stabilizing shafts 7, and the distance between the rotating shaft 11 and the stabilizing box 3 is adjusted according to the swing amplitude when the wire is fed.

[0046] When adjusting the distance between the rotating shaft 11 and the stabilizing box 3, the second vertical plate 54 is moved back and forth by the second electric push rod 85, and the distance between the rotating shaft 11 and the stabilizing box 3 changes when the second vertical plate 54 moves. At the same time, the distance between the stabilizing box 3 and the base plate 1 can be adjusted by the first electric push rod 2.

[0047] After the distance between the rotating shaft 11 and the stabilizer is adjusted, the drive motor 10 is turned on, so that the drive motor 10 drives the elliptical plate 12 to rotate. Then, through the pushing force of the rotating elliptical plate 12 and the spring 55 on the second vertical plate 54, the second vertical plate 54 moves back and forth. At this time, the swing amplitude of the stabilizer shaft 7 is the same as the swing amplitude when the wire is fed, so that the wire is not easily worn during the wire feeding process.

[0048] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
