Technical Field
[0001] This utility model relates to the field of punches, and more particularly to a punch structure with a stripping device. Background Art
[0002] Nowadays, punching machines and punches are needed for punching various workpieces and manufacturing parts. In order to ensure the accuracy of the punching hole position and the punching hole diameter, it is generally necessary to strictly control the model and specifications of the punch, as well as the quality and hardness of the punch. Therefore, the structural design of the punch is particularly important.
[0003] Currently, with the continuous development of science and technology, in order to improve production efficiency and ensure the quality of stamped parts, most punches are designed to be detachable. After a period of use, waste and debris tend to accumulate in the gaps on the surface of the punch. Therefore, it is necessary to disassemble and replace the entire punch from time to time, and to replace it with punches of different models and specifications.
[0004] However, most existing punches are one-piece designs. Since the punches do not have a material ejection device or structure to assist in material ejection, external force and tools are required to eject the material when the punch needs to be replaced, which is quite troublesome to use. Utility Model Content
[0005] To overcome the problem that most existing punches are one-piece designs, but because they do not have a material ejection device or structure to assist in material ejection, it is necessary to use external force and tools to eject the material when the punch needs to be replaced, which is quite troublesome.
[0006] The technical solution of this utility model is as follows: a punch structure with a material removal device, including a punch body, a sealing head detachably installed at the upper end of the punch body, a material removal head inside the punch body, a fixing head detachably installed inside the material removal head, a magnetic block fixedly installed at the top of the fixing head, uniformly distributed positioning rods fixedly installed on the lower side of the material removal head, a connecting head on the lower side of the material removal head, a positioning head on the lower side of the connecting head, a fixing sleeve fixedly installed at the lower end of the positioning head, an installation head inside the magnetic block, a punch rod fixedly connected to the lower surface of the installation head, and the punch rod extending downward to the outside of the fixing sleeve.
[0007] Preferably, during the punching process, the punch rod, in conjunction with the positioning head, collects the waste material and debris in the gap between the fixed sleeve and the punch rod. When it is necessary to remove the material, the sealing head can be opened first, and then the magnetic block in the removal head can be attracted by a magnet. Then, the position of the removal head can be moved back and forth inward and outward so that the removal head can impact the positioning head inside the punch body. When the positioning head vibrates, it will shake the waste material inside the fixed sleeve out of the fixed sleeve.
[0008] Preferably, a first washer is provided between the connector and the unloading head, and a second washer is provided between the magnetic block and the connector.
[0009] Preferably, the surfaces of the first washer and the second washer are provided with a circular hole one, and the surface of the connector is provided with a circular hole two. The positions of the circular holes one and two correspond to the positions of the positioning rod.
[0010] Preferably, the positioning rod extends through the first and second round holes to the upper surface of the positioning head.
[0011] Preferably, a ring is fixedly connected to the outer surface of the sealing head, and a tightening head is provided on the lower surface of the sealing head.
[0012] Preferably, the upper surface of the magnetic block is provided with a connecting groove corresponding to the tightening head.
[0013] Preferably, the outer surface of the punch body is provided with a groove, and the inner wall of the groove can be engraved with words.
[0014] The beneficial effects of this utility model are:
[0015] 1. This punch structure with a material stripping device, by setting a material stripping head, a fixed head, a connecting head, and a positioning rod, can collect waste material and debris in the gap between the fixed sleeve and the punch rod during the punching process, in conjunction with the positioning head. When material stripping is required, the sealing head can be opened first, and then the magnetic block in the material stripping head can be attracted by a magnet. Then, the position of the material stripping head can be moved back and forth inward and outward so that the material stripping head can impact the positioning head inside the punch body. When the positioning head vibrates, it will shake the waste material inside the fixed sleeve out of the fixed sleeve. Material stripping is not only convenient to install and disassemble, but also more convenient to strip. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please see Figures 1-5 This utility model provides an embodiment of a punch structure with a material removal device, including a punch body 1, a sealing head 5 detachably mounted on the upper end of the punch body 1, a material removal head 2 disposed inside the punch body 1, a fixing head 3 detachably mounted inside the material removal head 2, a magnetic block 4 fixedly mounted on the top of the fixing head 3, the magnetic block 4 being used to cooperate with a magnet to move the material removal head 2 by external force connection, a uniformly distributed positioning rod 6 fixedly mounted on the lower side of the material removal head 2, a connecting head 8 disposed on the lower side of the material removal head 2, a positioning head 9 disposed on the lower side of the connecting head 8, a fixing sleeve 10 fixedly mounted on the lower end of the positioning head 9, an installation head 12 disposed inside the magnetic block 4, a punch rod 11 fixedly connected to the lower surface of the installation head 12, the punch rod 11 extending downward to the outside of the fixing sleeve 10, the punch rod 11 being used for punching holes, a groove 101 being formed on the outer surface of the punch body 1, and characters being engraved on the inner wall of the groove 101.
[0024] Please see Figure 4 A first washer 7 is provided between the connector 8 and the stripper head 2, and a second washer 13 is provided between the magnetic block 4 and the connector 8. The first washer 7 and the second washer 13 can buffer the force and separate the two adjacent parts.
[0025] Please see Figures 2-4 The first washer 7 and the second washer 13 have a circular hole 701 on their surfaces, and the connector 8 has a circular hole 801 on its surface. The positions of the circular holes 701 and 801 correspond to the positions of the positioning rod 6. The positioning rod 6 extends through the circular holes 701 and 801 to the upper surface of the positioning head 9. The outer surface of the sealing head 5 is fixedly connected with a ring 502. The lower surface of the sealing head 5 is provided with a tightening head 501. The upper surface of the magnetic block 4 is provided with a connecting groove 401 corresponding to the tightening head 501. By providing the connecting groove 401, it cooperates with the tightening head 501 to fix the sealing head 5 on the punch body 1.
[0026] During operation, the entire punch assembly is first installed and then fixed onto the punching machine. During the punching process, the punch rod 11, in conjunction with the positioning head 9, collects the waste and debris in the gap between the fixed sleeve 10 and the punch rod 11. When material removal is required, the sealing head 5 can be opened first, and then the magnetic block 4 in the material removal head 2 can be attracted by the magnet. The position of the material removal head 2 can be moved back and forth inward and outward so that the material removal head 2 can impact the positioning head 9 inside the punch body 1. When the positioning head 9 vibrates, the waste inside the fixed sleeve 10 will be shaken out of the fixed sleeve 10. Material removal is not only convenient to install and disassemble, but also easier to remove.
[0027] Through the above steps, by setting the stripper head 2, fixing head 3, connecting head 8 and positioning rod 6, the waste material and debris can be collected in the gap between the fixing sleeve 10 and the punch rod 11 during the punching process in conjunction with the positioning head 9. When stripping is required, the sealing head 5 can be opened first, and then the magnetic block 4 in the stripper head 2 can be attracted by the magnet. Then, the position of the stripper head 2 can be moved back and forth inward and outward so that the stripper head 2 can impact the positioning head 9 inside the punch body 1. When the positioning head 9 vibrates, the waste material inside the fixing sleeve 10 will be shaken out of the fixing sleeve 10. There is no need to use external force and tools to strip the material. This solves the problem that most existing punches are one-piece, but because the punch does not have a stripping device or structure to assist stripping, it is more troublesome to use when the punch needs to be replaced later.
