Description

Technical Field

[0001] The invention relates to the technical field of punching dies, and more specifically to a punching die for high-precision hardware and a use method thereof. Background Art

[0002] Hardware refers to tools made of gold, silver, copper, iron, tin and other metals through processing and casting, which are used to fix things, process things, and decorate. High-precision hardware specifically refers to the hardware category with higher precision requirements in the hardware industry.

[0003] Pipe fittings are a common type of hardware. Some pipe fittings often require continuous punching processing, that is, punching multiple holes on a pipe fitting. Punching dies are usually required for punching.

[0004] When the punching die in the prior art is used for continuous punching of pipe fittings, the pipe material between adjacent holes is prone to inward concavity and deformation, resulting in punching failure or poor punching quality, which easily leads to the scrapping of the pipe fittings. Therefore, we propose a high-precision punching die for hardware and a method for using the same. Summary of the invention

[0005] 1. Technical issues to be solved

[0006] In view of the problems existing in the prior art, the purpose of the present invention is to provide a punching die for high-precision hardware and a method for using the same. The present invention arranges an anti-dent and burr detection component so that when punching a pipe fitting, the anti-dent inner support block can effectively support the pipe fitting from the inside of the pipe fitting, thereby preventing the pipe body from sinking and deforming inward during the processing, thereby effectively reducing the scrap rate of the pipe fitting. The mold can also perform burr detection on the processed holes, so that the staff does not need to perform burr detection on the holes later, which can effectively improve work efficiency. The marking auxiliary detection component is arranged so that after the start switch is triggered, the electric telescopic rod will also be started, so that the electric telescopic rod drives the piston plate to move upward a certain distance, causing part of the marking liquid to be sprayed onto the outer wall of the pipe fitting through the connecting pipe and the nozzle, so that marks can be made on the pipe fitting, making it easy for the staff to find holes with burrs, thereby improving practicality.

[0007] Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solutions.

Through the setting of the anti-dent and puncture detection component, when the pipe fitting is punched, the anti-dent inner support block can effectively support the pipe fitting from the inside of the pipe fitting, thereby preventing the pipe body from sinking and deforming inward during the processing, thereby effectively reducing the scrap rate of the pipe fitting, and the mold can also perform burr detection on the processed holes, so that the staff does not need to perform burr detection on the holes later, which can effectively improve work efficiency.

[0010] Furthermore, a marking aid is provided on the stamping die base, and the marking aid includes a marking receiving groove opened on the top of the stamping die base, a marking adjustment box is fixedly installed in the marking receiving groove, a piston plate is provided in the marking adjustment box and is slidingly and sealingly connected to the piston plate, and the top of the piston plate is filled with marking liquid.

[0011] Furthermore, an electric telescopic rod is fixedly connected to the inner wall of the bottom end of the mark storage groove, the output end of the electric telescopic rod is fixedly connected to the bottom end of the piston plate, and the electric telescopic rod is connected to the start switch signal.

[0012] Furthermore, the top of the mark receiving groove is connected to a connecting pipe, and the top of the connecting pipe is fixedly connected to a nozzle. The mark receiving groove is located on the left side of the stamping die hole. Through the setting of the marking auxiliary part, after the starting switch is triggered, the electric telescopic rod will also be started, so that the electric telescopic rod drives the piston plate to move upward a certain distance, causing part of the marking liquid to be sprayed onto the outer wall of the pipe through the connecting pipe and the nozzle, so that marks can be made on the pipe, making it easy for staff to find holes with burrs, thereby improving practicality.

[0013] Furthermore, a receiving die seat is arranged below the stamping die seat, and a connecting column is fixedly connected between the receiving die seat and the stamping die seat, so that waste generated by punching can fall onto the receiving die seat through the stamping die hole, thereby preventing waste from accumulating in the stamping die hole and affecting the punching process.

[0014] Furthermore, the built-in groove is filled with a magneto-variable filling liquid made of magnetorheological fluid. Electromagnets are fixedly connected to the inner walls on both sides of the left and right sides of the stamping die hole, so that when the pipe is punched by a machine tool, the electromagnet can be energized to make the magneto-variable filling liquid transform from liquid to solid under the action of the magnetic field of the electromagnet. The solid magneto-variable filling liquid can limit the movement of the trigger plate, thereby preventing the detection cylinder from moving during the punching process, causing the start switch to be triggered by mistake, thereby improving practicality.

[0015] Furthermore, the diameter of the punching die hole is larger than the inner diameter of the detection cylinder, and the inner diameter of the detection cylinder is larger than the diameter of the hole to be processed in the pipe to be processed, which is conducive to the falling of waste materials.

[0016] Furthermore, the length of the detection tube is 0.3-1 mm smaller than the depth of the punched hole, so that the upper and lower ends of the detection tube will not contact the inner wall of the pipe, thereby preventing the start switch from being triggered by mistake.

[0017] Furthermore, the outer cover of the starting switch is provided with an elastic sealing cover that matches it. The elastic sealing cover is made of elastic material. The elastic sealing cover is fixedly sealed and connected to the inner wall of the built-in groove.

[0019] S1, moving the mold to the processing table of the machine tool, and then sleeve the pipe to be processed onto the anti-dent inner support block 201;

[0020] S2, push the pipe fitting so that the opening position at the leftmost end of the pipe fitting matches the detection tube 203;

[0021] S3, punching the pipe fittings by machine tools;

[0023] Beneficial Effects

[0024] Compared with the prior art, the advantages of the present invention are:

[0025] (1) This solution uses the anti-dent and burr detection component to effectively support the pipe from the inside when punching the pipe, thereby preventing the pipe body from sinking and deforming inward during the processing, thereby effectively reducing the scrap rate of the pipe. In addition, this mold can also detect burrs on the processed holes, so that the staff does not need to perform burr detection on the holes later, which can effectively improve work efficiency.

[0026] (2) By setting up the marking aid, when the start switch is triggered, the electric telescopic rod will also be started, so that the electric telescopic rod drives the piston plate to move upward a certain distance, causing part of the marking liquid to spray onto the outer wall of the pipe through the connecting pipe and the nozzle, thereby making marks on the pipe, making it easier for workers to find holes with burrs, thereby improving practicality.

[0027] (3) A receiving die seat is provided below the stamping die seat, and a connecting column is fixedly connected between the receiving die seat and the stamping die seat, so that the waste generated by punching can fall through the stamping die hole to the receiving die seat, thereby preventing the waste from accumulating in the stamping die hole and affecting the punching process.

[0028] (4) The built-in groove is filled with a magnetorheological filling liquid made of magnetorheological fluid. Electromagnets are fixedly connected to the inner walls on both sides of the punching die hole. When the pipe is punched by the machine tool, the electromagnet can be energized to make the magnetorheological filling liquid change from liquid to solid under the action of the magnetic field of the electromagnet. The solid magnetorheological filling liquid can limit the movement of the trigger plate, thereby preventing the detection tube from moving during the punching process, causing the start switch to be triggered by mistake, thereby improving practicality.

[0029] (5) The length of the detection tube is 0.3-1 mm smaller than the depth of the punched hole, so that the upper and lower ends of the detection tube will not contact the inner wall of the pipe fitting, thereby preventing the start switch from being triggered by mistake.

[0030] (6) The outer cover of the start switch is provided with an elastic sealing cover that matches it. The elastic sealing cover is made of elastic material. The elastic sealing cover is fixedly sealed and connected to the inner wall of the built-in groove. The elastic sealing cover can prevent the liquid magnetic variable filling fluid from damaging the start switch without affecting the triggering of the start switch.

A trigger plate 206 is movably installed in the built-in groove 204, and a plurality of connecting rods 207 are fixedly connected to one end of the trigger plate 206 close to the detection tube 203. The connecting rods 207 penetrate the outer wall of the built-in groove 204 and extend to be fixedly connected to the detection tube 203, and the connecting rods 207 are slidingly and sealingly connected to the outer wall of the built-in groove 204. A starting switch 208 is fixedly installed on the inner wall of the built-in groove 204. The anti-dent detection assembly also includes a reminder light 209 fixedly installed on the stamping die base 101, and the starting switch 208 is connected to the reminder light 209 by signal.

[0048] See also Figure 8-9By setting the anti-dent and burr detection component, when punching the pipe fitting, the anti-dent inner support block 201 can effectively support the pipe fitting from the inside of the pipe fitting, so as to prevent the pipe body from being deformed inward during the processing, thereby effectively reducing the scrap rate of the pipe fitting. After one hole is processed, when the pipe fitting is moved to prepare for the processing of the next hole, if there are burrs on the inner wall of the pipe fitting due to punching, the burrs will push the detection cylinder 203 during the moving process of the pipe fitting, so that the detection cylinder 203 moves. The movement of the detection cylinder 203 will drive the trigger plate 206 to move through the connecting rod 207, so that the trigger plate 206 squeezes and triggers the start switch 208. After the start switch 208 is triggered, the reminder light 209 will be lit, so as to remind the staff that there are burrs at the hole just processed, so that the mold can perform burr detection on the processed holes, so that the staff does not need to perform burr detection on the holes later, which can effectively improve the work efficiency.

[0049] See also Figure 1 A receiving die base 102 is provided below the stamping die base 101, and a connecting column 103 is fixedly connected between the receiving die base 102 and the stamping die base 101, so that the waste generated by punching can fall onto the receiving die base 102 through the stamping die hole 106, thereby preventing the waste from accumulating in the stamping die hole 106 and affecting the punching process.

[0051] See also Figure 4 The length of the detection tube 203 is 0.3-1 mm smaller than the depth of the punching hole 202, so that the upper and lower ends of the detection tube 203 will not contact the inner wall of the pipe, thereby preventing the start switch 208 from being triggered by mistake.

[0052] See also Figure 4 and Figure 6 The built-in groove 204 is filled with a magnetorheological filling liquid 205, which is made of magnetorheological fluid. The inner walls on both sides of the stamping die hole 106 are fixedly connected with electromagnets 301, so that when the pipe is punched by the machine tool, the electromagnet 301 can be energized to make the magnetorheological filling liquid 205 change from liquid to solid under the action of the magnetic field of the electromagnet 301. The solid magnetorheological filling liquid 205 can limit the movement of the trigger plate 206, thereby preventing the detection tube 203 from moving during the punching process, causing the start switch 208 to be triggered by mistake, thereby improving practicality. In addition, after the punching is completed, before moving the pipe, the electromagnet 301 is powered off, which will not affect the triggering of the detection function of the anti-dent detection component.

The mark receiving groove 401 is located on the left side of the stamping die hole 106. Through the setting of the marking auxiliary component, after the start switch 208 is triggered, the electric telescopic rod 405 will also be started, so that the electric telescopic rod 405 drives the piston plate 403 to move upward a certain distance, causing part of the marking liquid 404 to spray onto the outer wall of the pipe through the connecting pipe 406 and the nozzle 407, so that marks can be made on the pipe, making it easier for staff to find holes with burrs, thereby improving practicality.

[0054] See also Figure 5 The outer cover of the start switch 208 is provided with an elastic sealing cover 210 that matches it. The elastic sealing cover 210 is made of elastic material.
