[0002] Stainless steel wire can also be called stainless steel wire, stainless steel wire rod, and stainless steel coil element, but unlike stainless steel wire rope, stainless steel wire is mainly divided into spring wire and screw wire. As the name suggests, screw wire is mainly used to make screws, while spring wire is used to make springs or other hardware products that require elasticity.

[0003] The existing technology mostly adopts a steel wire stamping device disclosed in the announcement number CN215203563U, which includes a base, a lower module and an upper module; a fixing frame is provided on the upper side of the base, and the fixing frame is a "U"-shaped structure, and wire placement holes are respectively opened on the left and right sides of the vertical end of the fixing frame. This technology is convenient for replacing the stamping module, has low labor intensity and high work efficiency, but the above technology still has problems in use due to structural limitations:

[0004] If stainless steel wire is used as raw material to manufacture step bolts, since there are three cylinders with decreasing diameters on the step bolts, the stainless steel wire needs to be stamped twice in sequence when processing the step bolts. At the same time, the sizes of the dies used in the two stamping operations decrease, so that three cylinders with decreasing diameters are formed on the stainless steel wire, and the step bolts are processed based on this. However, the multiple stamping dies in the above technology are of the same size. Therefore, after completing the first stamping, the wire needs to be removed immediately and the stamping die needs to be replaced before the second stamping can be continued. As a result, the two stamping operations cannot be completed continuously, which seriously affects the manufacturing efficiency of the step bolts. Summary of the invention

Fig. 22 The step bolts shown are provided on the frame 1, and a switching mechanism is provided for switching the state where the lower fixed die groove 3 is flush with the first conversion die groove 5, and the state where the second conversion die groove 6 and the fourth conversion die groove 12 correspond to each other up and down, so as to facilitate two consecutive stamping processes on the wire to be processed.

[0049] Furthermore, the lower end of the frame 1 is fixedly connected with a first transverse slide rail 13, and both ends of the first transverse slide rail 13 are fixedly connected with transverse cylinders 14. A sliding mounting frame 15 and a first U-shaped mounting frame 19 are slidingly sleeved in the first transverse slide rail 13. A vertical slide groove 16 is provided on the sliding mounting frame 15, and a second U-shaped mounting frame 17 is provided at the upper end of the sliding mounting frame 15. A vertical long block 18 is fixedly connected to the lower end of the second U-shaped mounting frame 17, and the vertical long block 18 is movably sleeved in the vertical slide groove 16. The output ends of the two transverse cylinders 14 are respectively fixedly connected to the lower end of the first U-shaped mounting frame 19 and the sliding mounting frame 15, and then the first U-shaped mounting frame 19 and the sliding mounting frame 15 are respectively moved in contact with or separated from each other through the two transverse cylinders 14. When the contact movement is performed, the wire to be processed can be subjected to the first stamping process. When the separation movement is performed, the processing position of the wire to be processed is adjusted, and the wire to be processed can be subjected to the second stamping process. Fig.15 As shown, the lower end fixing module 2 is fixedly connected to the second U-shaped mounting frame 17 by bolts, so that the severely worn lower end fixing module 2 can be replaced in time.

[0050] At the same time, the first U-shaped installation frame 19 has first rotating shafts 20 rotatably mounted at both ends, and both ends of the first rotating shaft 20 extend to the inner and outer sides of the first U-shaped installation frame 19, respectively. Fig.16 As shown, the inner extension ends of the two first rotating shafts 20 are fixedly connected to the middle end of the lower conversion module 4 through a disc and bolts, so as to facilitate the replacement of the lower conversion module 4. A push cylinder 21 is fixedly installed on the upper end of the frame 1, and a second transverse slide rail 22 is fixedly connected to the output end of the push cylinder 21;

[0051] Further, a third U-shaped mounting frame 23 is slidably connected in the second transverse slide rail 22, and a second rotating shaft 24 is rotatably mounted on both ends of the third U-shaped mounting frame 23, and both ends of the second rotating shaft 24 extend to the inner and outer sides of the third U-shaped mounting frame 23, respectively. Fig.11 and attached Fig.12 As shown, the inner extending ends of the two second rotating shafts 24 are fixedly connected to the middle end of the upper conversion module 9 through a disc and bolts to facilitate the replacement of the upper conversion module 9.

[0052] The switching mechanism includes a first vertical slide rail 45 fixedly mounted on the sliding mounting frame 15, a lifting cylinder 25 fixedly connected to the first vertical slide rail 45, an L-shaped moving rod 26 fixedly connected to the outer side of the second U-shaped mounting frame 17 through a horizontal long block, the L-shaped moving rod 26 is slidably connected to the traction long rod 27, a fixed sleeve 7 is fixedly connected to the first horizontal slide rail 13, a sliding sleeve in the fixed sleeve 7 is provided with a placement ring 8 fixedly connected to the traction long rod 27, the placement ring 8 can move in the vertical direction together with the lower fixed mold groove 3, and at the same time, the sliding connection between the traction long rod 27 and the L-shaped moving rod 26 is utilized to allow the lower fixed mold groove 3 to move in the horizontal direction relative to the placement ring 8.

[0053] It is particularly noted that the placement ring 8 is arranged at the same center as the lower fixed die groove 3, and the specification of the placement ring 8 is larger than that of the lower fixed die groove 3, so that the rough state of the wire to be processed can pass through the placement ring 8, and the bottom end of the placement ring 8 is located below the bottom of the lower fixed die groove 3. Before the wire to be processed is subjected to the first stamping process, since the lower fixed die groove 3 and the first conversion die groove 5 are located at the middle end of the wire to be processed, the wire to be processed is at the same height as a whole. When the wire to be processed completes the first stamping process and moves upward driven by the lower fixed die groove 3, the bottom end of the placement ring 8 contacts the rough state of the wire to be processed, and the first stamping place of the wire to be processed contacts the bottom of the lower fixed die groove 3, so that the axes of various parts of the wire to be processed are at the same height.

[0054] Furthermore, the switching mechanism also includes a first limit plate 28 and a second limit plate 35 which are respectively slidably mounted on the two ends of the inner side of the first U-shaped mounting frame 19, and the two ends of the inner side of the first U-shaped mounting frame 19 are fixedly connected with a first limit cylinder 29, and the output ends of the two first limit cylinders 29 are respectively fixedly connected with the first limit plate 28 and the second limit plate 35. After the lower end conversion module 4 completes the rotation, the first limit plate 28 and the second limit plate 35 can be used to clamp and limit the lower end conversion module 4 to prevent the lower end conversion module 4 from rotating during the stamping process. Fixed openings 30 are opened through the two ends of the inner side of the first U-shaped mounting frame 19, and the first limit plate 28 extends the first U-shaped mounting frame 19 from one of the fixed openings 30 through the first extension rod, and the second limit plate 35 extends the first U-shaped mounting frame 19 from the other fixed opening 30 through the second extension rod. The first extension rod and the second extension rod are respectively fixedly connected with a second vertical slide rail 31 and a vertical moving rod 36.

[0055] The switching mechanism also includes a double-toothed tooth bar 32 slidably sleeved in the second vertical slide rail 31, wherein one of the first rotating shafts 20 has an outer extending end key connected to a first gear 33, and one of the second rotating shafts 24 has an outer extending end key connected to a second gear 34, and when the first limiting plate 28 limits or releases the limit of the lower end conversion module 4, the double-toothed tooth bar 32 is separated from or meshed with the first gear 33 and the second gear 34 respectively;

When the driving motor 37 drives the first rotating shaft 20 to rotate, the double-toothed gear 32 is meshed with the first gear 33 and the second gear 34 to allow the lower end conversion module 4 and the upper end conversion module 9 to rotate simultaneously. Figure 2 and attached Fig.11 As shown, the fourth conversion die groove 12 is located above the second conversion die groove 6, and the avoidance groove 10 is located above the lower fixed die groove 3, and the fourth conversion die groove 12 is used for a second stamping process, and the avoidance groove 10 is used to avoid the wire to be processed at the lower fixed die groove 3;

[0057] The upper and lower ends of the rotating block 38 are respectively provided with a first limiting groove 39 and a second limiting groove 40. An L-shaped fixing block 43 is fixedly connected to the outer side of the third U-shaped mounting frame 23. The L-shaped fixing block 43 is provided with a connecting fixing groove 44. When the second limiting plate 35 limits or releases the limit on the lower end conversion module 4, the connecting protrusion is separated or connected with the connecting fixing groove 44 respectively. When the connecting protrusion is connected with the connecting fixing groove 44, as shown in the attached Fig. 9As shown, the first U-shaped mounting frame 19 drives the upper conversion module 9 to move together through the connecting protrusion and the connecting fixing groove 44, so that the attached Fig. 9 The left end of the lower conversion module 4 and the left end of the upper conversion module 9 are flush, so that the fourth conversion mold groove 12 is aligned with the second conversion mold groove 6. Fig.14 As shown, a driving cylinder and a driving clamping plate for clamping the third U-shaped mounting frame 23 are provided in the second transverse slide rail 22, so as to clamp and limit the movable third U-shaped mounting frame 23 and the upper conversion module 9.

[0058] Furthermore, the second U-shaped mounting frame 17 is slidably sleeved in the first vertical slide rail 45 , and the output end of the lifting cylinder 25 is fixedly connected to the second U-shaped mounting frame 17 , so that the second U-shaped mounting frame 17 is lifted and moved by the lifting cylinder 25 .

[0059] Furthermore, the first gear 33 and the second gear 34 are respectively located at the lower right end and the upper left end of the double-toothed bar 32. When the L-shaped movable rod 26 is movably sleeved in the first limiting groove 39, the lower end fixed die groove 3 is prevented from continuing to move downward, and the bottom of the lower end fixed die groove 3 is made to be at the same height as the bottom of the first conversion die groove 5, so as to facilitate the first stamping of the wire to be processed at the lower end fixed die groove 3 and the first conversion die groove 5. When the L-shaped movable rod 26 is movably sleeved in the second limiting groove 40, the lower end fixed die groove 3 is prevented from continuing to move downward, and the bottom of the lower end fixed die groove 3 is made to be at the same height as the bottom of the wire to be processed placed on the second conversion die groove 6, so as to avoid bending of the two ends of the wire to be processed after the second stamping.

[0060] A third limiting plate 41 is slidably provided on both ends of the inner side of the third U-shaped mounting frame 23, and a second limiting cylinder 42 is fixedly connected to both ends of the inner side of the third U-shaped mounting frame 23, and the output ends of the two second limiting cylinders 42 are respectively fixedly connected to the two third limiting plates 41. After the upper end conversion module 9 completes the rotation, the two third limiting plates 41 are used to clamp and limit the upper end conversion module 9 to prevent the upper end conversion module 9 from rotating during stamping.

[0061] The present invention can be explained by the following operation mode:

[0062] First, pass the wire to be processed through the placement ring 8, as shown in the attached Figure 1 As shown, at this time, the lower fixed die groove 3 is flush with the first conversion die groove 5, and then placed on the lower fixed die groove 3 and the first conversion die groove 5, and the push cylinder 21 is started, so that the output end of the push cylinder 21 drives the third conversion die groove 11 to move downward through the upper conversion module 9, as shown in the attached Fig. 20 As shown, the wire material to be processed at the lower fixed die groove 3 and the first conversion die groove 5 is subjected to a first stamping process, so that the diameter of the wire material to be processed at the first stamping process becomes smaller and longer;

[0063] After the first stamping process, the two second limit cylinders 42 are started, as shown in the attached Fig.11 As shown, the output ends of the two second limit cylinders 42 drive the two third limit plates 41 to move away from each other in the opposite direction to release the clamping limit of the upper conversion module 9, and then start the two first limit cylinders 29, as shown in the attached figure. Figure 5 and attached Figure 7 As shown, the output end of the first limit cylinder 29 drives the first limit plate 28 and the second limit plate 35 to move away in the opposite direction to release the clamping limit of the lower end conversion module 4. At the same time, the first limit plate 28 and the second limit plate 35 drive the double-tooth tooth bar 32 and the vertical moving rod 36 to move away in the opposite direction, so that the double-tooth tooth bar 32 moves to a position where it is meshed with the first gear 33 and the second gear 34, and the connection protrusion on the vertical moving rod 36 moves to the connection fixing groove 44;

[0064] Then start the two transverse cylinders 14, as shown in the attached Figure 5 As shown, the two transverse cylinders 14 drive the first U-shaped mounting frame 19 and the sliding mounting frame 15 to move away from each other in the opposite direction. At this time, the first stamping processing position of the wire material to be processed is still located in the lower fixed die groove 3 and the first conversion die groove 5, and the first U-shaped mounting frame 19 drives the upper conversion module 9 to move together through the connecting protrusion and the connecting fixed groove 44, and then the lifting cylinder 25 is started, as shown in the attached figure. Figure 7 As shown, the output end of the lifting cylinder 25 drives the lower fixed die groove 3 and the L-shaped moving rod 26 to move upward, so that the L-shaped moving rod 26 is separated from the first limiting groove 39, and the wire to be processed is lifted by the cooperation of the placement ring 8;

[0065] Then, the driving motor 37 is started, and the output end of the driving motor 37 drives one of the first rotating shafts 20 to rotate, as shown in the attached figure. Figure 7 As shown, the first rotating shaft 20 drives the first gear 33 and the lower conversion module 4 to rotate clockwise, and the first gear 33 drives the double-toothed tooth bar 32 to move upward, and at the same time, the double-toothed tooth bar 32 drives the second gear 34 to rotate counterclockwise, and the second rotating shaft 24 drives the upper conversion module 9 to rotate counterclockwise, thereby changing the positions of the second conversion die groove 6 and the fourth conversion die groove 12, and making the second conversion die groove 6 correspond to the fourth conversion die groove 12 up and down;

[0066] At the same time, one of the first rotating shafts 20 drives the rotating block 38 to rotate clockwise.
