Description

Technical Field

[0001] The present application relates to the field of anti-falling chain production, and in particular to a positioning tool for a punching die. Background Art

[0002] When producing anti-fall chains, the middle rope needs to be connected to the connectors at both ends. The connection method is to insert the two ends of the rope into the holes of different connectors respectively, and then fix the ends of the rope to the main body of the rope by riveting.

[0003] At present, when producing anti-fall chains, the rope body and the ends of the rope are positioned by workers by pinching them with their fingers. On the one hand, it is highly dangerous, and on the other hand, the positioning is poor, affecting product quality. Utility Model Content

[0004] In order to improve the problem of high risk of chain fall prevention in production, the present application provides a positioning tool for a die.

[0005] The present application provides a positioning tool for a punching die, which adopts the following technical solution:

[0006] A positioning tool for a punching die comprises a fixed block, on which a swing block is rotatably arranged, and the swing block is rotated to clamp a rope on the fixed block.

[0007] By adopting the above technical solution, the rope is pressed onto the fixed block by rotating the swing block, thereby fixing the position of the rope. This eliminates the need for workers to manually press the rope during riveting, greatly improving safety and reducing danger.

[0008] Optionally, a positioning gap is formed between the swing block and the fixed block, the positioning gap is used to clamp the rope, and an elastic member is provided between the swing block and the fixed block, the elastic member is used to push the swing block in a direction to reduce the positioning gap.

[0009] By adopting the above technical solution, the swinging member is rotated toward the fixed block by the elastic force of the elastic member, so that the rope is clamped in the positioning gap, which is convenient, fast and stable, and improves product quality.

[0010] Optionally, when the swing block and the fixed block are in a rope clamping state, the cross-sectional spacing of the positioning gap is larger as it is closer to the rotation axis of the swing block.

[0011] By adopting the above technical solution, it is convenient to take the rope in the positioning gap out of the positioning gap opening. The closer the position is to the positioning gap opening, the greater the clamping force, that is, the rope located deep in the positioning gap is subjected to less force, which is convenient for adjustment. The inclined inner wall of the positioning gap can also be used to directly pull the rope out, and the swing block will automatically give way, which is convenient and quick.

[0012] Optionally, an interference hook is provided on the fixed block, the interference hook is in contact with the swing block, and the interference hook is used to limit the maximum rotation angle of the swing block pushed by the elastic member.

[0013] By adopting the above technical solution, the maximum swing angle of the swing block is limited by the interference hook, thereby controlling the minimum spacing of the positioning gap, making it easier to put the rope into the positioning gap.

[0014] Optionally, rounded corners are formed on the edges of the fixed block and the swing block, and the rounded corners serve as the edges of the opening surface of the positioning gap.

[0015] By adopting the above technical solution, when the rope is put into the positioning gap from the opening surface of the positioning gap, the rounded corners give way to guide the swing block to give way and rotate under the pressure of the rope, which is convenient and quick.

[0016] Optionally, the elastic member and the positioning gap are symmetrically located on both sides of the rotation axis of the swing block.

[0017] By adopting the above technical solution, the probability of the rope contacting the elastic part, thereby causing the elastic part to interfere with the rope processing, is reduced, the elastic part and the positioning gap are separated by a certain distance, and the safety and stability are improved.

[0018] Optionally, a first extending block is provided on the swing block, and the first extending block is aligned with the fixed block in the rotation direction of the swing block.

[0019] By adopting the above technical solution, the rope is clamped by aligning the first extension block with the fixed block, so that the clamping is more stable.

[0020] Optionally, a second extending block is provided on the fixed block, and the second extending block is aligned with the swing block in the rotation direction of the swing block.

[0021] By adopting the above technical solution, the rope is clamped by aligning the second extension block with the swing block, making the clamping more stable.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. There is no need for staff to manually press the rope, which greatly improves safety and reduces danger.

[0024] 2. It is convenient to put the rope into the positioning gap and also convenient to take the rope out of the positioning gap.

[0025] 3. Improve the stability of rope position fixation and improve product quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] The present application embodiment discloses a positioning tool for a punching die. Figure 1 and Figure 2 The positioning tool for the punching die includes a fixed block 1, a rope and a connecting piece are processed on a processing table, the fixed block 1 is fixedly connected to the processing table, and a connecting table 3 for preventing the connecting piece from being connected is also fixedly connected to the processing table. In this embodiment, the direction of gravity is downward, and the direction opposite to downward is upward. A swing block 11 is rotatably connected to the fixed block 1, and the hinged position of the rotating shaft of the fixed block 1 and the swing block 11 is in the middle section of the length direction of the swing block 11. The swing block 11 is rotated to clamp the rope on the fixed block 1. In this embodiment, the part above the rotating shaft of the swing block 11 is the upper end, and the part below is the lower end.

[0032] Reference Figure 2, a positioning gap 12 is formed between the upper end of the swing block 11 and the upper end of the fixed block 1, and the positioning gap 12 is located above the rotation axis of the fixed block 1, and the positioning gap 12 is used to clamp the rope. An elastic member 13 is in contact between the lower end of the swing block 11 and the lower end of the fixed block 1. In this embodiment, the elastic member 13 is a spring, and other components with telescopic elasticity such as tension springs and springs can also be used. The elastic member 13 is used to push the swing block 11 in a direction of reducing the positioning gap 12. The elastic member 13 is always in a compressed state to eject the lower end of the swing block 11 away from the lower end of the fixed block 1, so as to reduce the positioning gap 12 formed between the upper end of the swing block 11 and the upper end of the fixed block 1. That is, the elastic member 13 and the positioning gap 12 are symmetrically located on both sides of the rotation axis of the swing block 11. In this embodiment, the rope is pressed on the fixed block by the elastic force of the elastic member 13 by rotating the swing block left and right. In other embodiments, the swing block can also be set to rotate horizontally up and down, and the rope is pressed on the fixed block by gravity. This method does not require the elastic member 13.

[0033] Reference Figure 1 and Figure 2 and Figure 3 The laying chain adapted for the positioning tool is a rope and two connecting pieces. As shown in the figure, the rope first passes through the positioning gap 12, then passes through the hole in the connecting piece placed on the connecting platform 3, and then passes back into the positioning gap 12, and then the ropes stacked in the positioning gap 12 are riveted.

[0034] Reference Figure 2 A contact hook 2 is fixedly connected to the lower end of the fixed block 1, and the contact hook 2 extends toward the side wall of the swing block 11 facing away from the fixed block 1. The end of the contact hook 2 contacts the side wall of the swing block 11 facing away from the fixed block 1. The lower end of the contact hook 2 rotates in the space formed between the end of the contact hook 2 and the side wall of the fixed block 1 facing the contact hook 2. The elastic member 13 is in this space, and the elastic member 13, the lower end of the contact hook 2, and the end of the contact hook 2 away from the fixed block 1 are sequentially distributed in the direction away from the fixed block 1. One end of the elastic member 13 contacts the side wall of the fixed block 1 facing the swing block 11, and the other end of the elastic member 13 contacts the side wall of the swing block 11 facing the fixed block 1. The elastic member 13 pushes the lower end of the swing block 11 in the direction away from the lower end of the fixed block 1 to contact the end of the contact hook 2 away from the fixed block 1. The contact hook 2 is used to limit the maximum rotation angle of the swing block 11 pushed by the elastic member 13.

[0035] Reference Figure 2When the lower end of the swing block 11 abuts against the end of the abutting hook 2 so that the upper end of the swing block 11 and the upper end of the fixed block 1 are in a state of clamping the rope, the cross-sectional spacing of the positioning gap 12 becomes larger as it is closer to the rotation axis of the swing block 11, that is, the upper end opening of the positioning gap 12 serves as an opening surface, and the positioning gap 12 is configured as a shrinkage. The positioning gap 12 has two inner walls, one inner wall is the side wall of the upper end of the swing block 11 facing the fixed block 1, and the other inner wall is the side wall of the upper end of the fixed block 1 facing the swing block 11. The spacing between the two inner walls of the positioning gap 12 is the cross-sectional spacing, and the cross-sectional spacing of the opening surface of the positioning gap 12 is slightly smaller than the rope diameter. For example, if the rope diameter is 3 mm, the cross-sectional spacing of the opening surface of the positioning gap 12 is 1 mm, and the cross-sectional spacing of the position of the positioning gap 12 closest to the rotation axis on the fixed block 1 is 3 mm.

[0036] Reference Figure 2 A rounded corner 21 is formed on the edges of the upper end of the fixed block 1 and the upper end of the swing block 11 , and the rounded corner 21 serves as the edge of the opening surface of the positioning gap 12 .

[0037] Reference Figure 2 The upper end of the swing block 11 is fixedly connected with a first extension block 22, the extension direction of the first extension block 22 is parallel to the extension direction of the rotation axis of the swing block 11, and the first extension block 22 is aligned with the upper end of the fixed block 1 in the rotation direction of the swing block 11. The fixed block 1 is fixedly connected with a second extension block 23, the extension direction of the second extension block 23 is parallel to the extension direction of the rotation axis of the swing block 11, and the second extension block 23 is aligned with the swing block 11 in the rotation direction of the swing block 11.

[0038] The implementation principle of a positioning tool for a punching die in the embodiment of the present application is as follows: when it is necessary to process the falling chain, the connecting piece is put on the connecting platform 3, and then the rope is put into the positioning gap 12 from the opening surface of the positioning gap 12. At this time, the swing block 11 is guided by the rounded corner 21 and squeezed by the rope. The upper end of the swing block 11 rotates in a direction away from the upper end of the fixed block 1, and the elastic piece 13 is compressed at the same time. When the rope completely enters the positioning gap 12, the elastic piece 13 releases the elastic force to make the upper end of the swing block 11 rotate close to the upper end of the fixed block 1 to narrow the positioning gap 12, and then the end of the rope passes through The hole of the connecting piece placed on the connecting platform 3 is passed back to the top of the opening surface of the positioning gap 12, and then the end of the rope is passed downward through the positioning gap 12 and pressed into the positioning gap 12. At this time, since there is a rope in the positioning gap 12, the end of the rope cannot be pressed to the bottom of the positioning gap 12, but can only be in the upper middle position of the positioning gap 12. At this time, under the elastic force of the elastic member 13, the swing block 11 continues to apply rotational pressure in the direction close to the fixed block 1, thereby clamping the end of the rope. At this time, the staff can loosen the rope to perform riveting, which greatly improves safety.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
