Description

Technical Field

[0001] This invention relates to the technical field of angle steel manufacturing, and in particular to a punch and an angle steel punching machine. Background Technology

[0002] The angle steel punching machine consists of a manual or electric pump and a working head. The oil delivery hose uses a quick connector for reliable sealing, fast operation, no directional restrictions, and easy assembly and disassembly. This machine is specifically designed for punching holes in metal sheets such as angle iron, flat iron, copper, and aluminum strips. It is used for punching angle steel. During operation, simply put the angle steel into the feed inlet, set the processing requirements, and it will start processing. It is highly efficient and produces a flat end face.

[0003] During production practice, it was found that the principle of punching equipment is to use a punch to work on angle steel under high pressure, thereby achieving punching. The advantage of this method is that the hole is flat, but the disadvantage is that the punch is easily damaged by cyclic stress. Although the punch is made of hard alloy steel, which has good wear resistance, it has become a consumable under the large-scale operation of nuclear power plants. When the punch is damaged, since the existing punches are all integrated, when the staff needs to replace the entire punch, the entire punch must be disassembled, which increases the production cost. At the same time, since the entire punch must be replaced after the tip is damaged, the labor intensity of the staff is high, which affects the overall work efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a punch and angle steel punching machine to solve the technical problem in the prior art where the punch is damaged by periodic stress during operation, and the entire punch needs to be replaced after the tip is damaged, which increases the labor intensity of workers and affects the overall work efficiency.

[0005] In a first aspect, the present invention provides a punch, including a base, a buffer, a punching part, and a connector, wherein the buffer and the punching part are detachably connected to the connector, and the punching part extends out of the connector;

[0006] The end of the connector facing away from the punched part is detachably connected to the base; and the buffer is installed between the base and the punched part.

[0007] In conjunction with the embodiments of the first aspect, the present invention provides a first possible embodiment of the first aspect, wherein the connector is provided with a receiving cavity, and the receiving cavity is provided with an internal thread;

[0008] The punched part and the buffer part are threadedly connected to the receiving cavity.

[0009] In conjunction with the first possible implementation of the first aspect, the present invention provides a second possible implementation of the first aspect, wherein the base includes a base and a limiting post, the limiting post being disposed at the end of the base facing the connector, and the limiting post being inserted into the receiving cavity of the connector;

[0010] The limiting post abuts against the end face of the buffer member away from the punched member, and the limiting post is used to restrict the movement of the buffer member.

[0011] In conjunction with the second possible implementation of the first aspect, the present invention provides a third possible implementation of the first aspect, wherein the inner wall of the end of the receiving cavity facing the base is provided with an insertion surface, and the limiting post is inserted into the receiving cavity along the insertion surface; the insertion surface is a smooth surface.

[0012] In conjunction with the third possible implementation of the first aspect, the present invention provides a fourth possible implementation of the first aspect, wherein the end of the connector away from the punched part abuts against the end face of the base where the limiting post is provided.

[0013] In conjunction with the third possible implementation of the first aspect, the present invention provides a fifth possible implementation of the first aspect, wherein the buffer is a columnar joint and the buffer is provided with a through hole, the through hole being filled with a vibration damping material.

[0014] In conjunction with the fifth possible implementation of the first aspect, the present invention provides a sixth possible implementation of the first aspect, wherein the outer wall of the buffer member is provided with an external thread adapted to the internal thread.

[0015] In conjunction with the second possible implementation of the first aspect, the present invention provides a seventh possible implementation of the first aspect, wherein the punched part is a columnar structure, and the punched part includes a contact portion and a connecting portion, the connecting portion being disposed at the end of the contact portion facing the buffer member;

[0016] The connecting part is used for detachably connecting the connector.

[0017] In conjunction with the sixth possible implementation of the first aspect, the present invention provides an eighth possible implementation of the first aspect, wherein the radial cross-sectional area of ​​the contact portion is smaller than the radial cross-sectional area of ​​the connecting portion.

[0018] Secondly, the present invention also provides an angle steel punching machine, including the punch described above.

[0019] The embodiments of the present invention bring the following beneficial effects: By employing a base, a buffer, a punch, and a connector, with the buffer and punch detachably connected to the connector and the punch extending beyond the connector, the operator can detachably connect the connector to the base by positioning the end of the connector away from the punch, thus achieving a detachable connection of the punch. This facilitates punch replacement. Simultaneously, installing the buffer between the base and the punch reduces the impact of the punch on the base during operation, extending the equipment's service life and ensuring the punch has sufficient power for drilling. This alleviates the technical problem in the prior art where the punch is damaged by cyclic stress during operation, requiring complete replacement of the entire punch after the tip is damaged.

[0025] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] like Figure 1 - Figure 3 As shown, the present invention provides a punch, including a base 100, a buffer 200, a punch 300, and a connector 400. The buffer 200 and the punch 300 are detachably connected to the connector 400, and the punch 300 extends out of the connector 400.

[0029] The end of the connector 400 facing away from the punched part 300 is detachably connected to the base 100; and the buffer 200 is installed between the base 100 and the punched part 300.

[0030] The device employs a base 100, a buffer 200, a punch 300, and a connector 400. The buffer 200 and the punch 300 are detachably connected to the connector 400, with the punch 300 extending beyond the connector 400. Workers can detachably connect the connector 400 to the base 100 by positioning the end of the connector 400 away from the punch 300, facilitating punch replacement. Simultaneously, installing the buffer 200 between the base 100 and the punch 300 reduces the impact of the punch 300 on the base 100 during operation, extending the device's lifespan and ensuring sufficient power for drilling. This alleviates the technical problem in existing technologies where the punch is damaged by cyclic stress, requiring complete replacement of the entire punch after the tip is damaged. This reduces the labor intensity of punch replacement and improves work efficiency.

[0031] It should be noted that the base 100, buffer 200, punching part 300 and connecting part 400 provided in this embodiment can all be processed directly in the workshop, which greatly reduces the cost required for punch production.

[0032] Furthermore, the connector 400 is provided with a receiving cavity, and the receiving cavity is provided with an internal thread; the punched part 300 and the buffer part 200 are threadedly connected to the receiving cavity.

[0033] The connector 400 can be machined with a hollow structure so that the receiving cavity is located inside the connector 400. Since the receiving cavity is provided with internal threads, the punched part 300 and the buffer part 200 can be detachably connected to the receiving cavity by means of threaded connection.

[0034] It should be noted that in this embodiment, the connector 400 is a cylindrical structure. The operator can complete the detachable connection between the buffer 200, the connector 400 and the punched part 300 by rotating the connector 400, the punched part 300 and the buffer 200 relative to each other, which is not limited by the operating environment and increases the application scenarios.

[0035] Furthermore, the base 100 includes a base 110 and a limiting post 120. The limiting post 120 is located at the end of the base 110 facing the connector 400 and is inserted into the receiving cavity of the connector 400.

[0036] The limiting post 120 abuts against the end face of the buffer 200 away from the punched part 300, and the limiting post 120 is used to restrict the movement of the buffer 200.

[0037] To prevent unnecessary slippage between the buffer 200 and the punched part 300 during high-speed operation within the connector 400, in this embodiment, the base 100 includes a base 110 and a limiting post 120. The limiting post 120 is located at the end of the base 110 facing the connector 400 and is inserted into the receiving cavity of the connector 400. By abutting against the end face of the buffer 200 away from the punched part 300, the buffer 200 and the punched part 300 can be tightly fitted together.

[0038] It should be noted that the base 100 also includes multiple adjustment plates, which are adapted to the shape of the limiting post 120 facing the buffer 200. During installation, the operator can control the fit between the limiting post 120 and the buffer 200 by adjusting the number of adjustment plates.

[0039] Furthermore, the inner wall of the end of the receiving cavity facing the base 100 is provided with an insertion surface, and the limiting post 120 is inserted into the receiving cavity along the insertion surface;

[0040] The insertion surface is smooth.

[0041] The inner wall of the end of the receiving cavity facing the base 100 is provided with an insertion surface. The insertion surface is a smooth surface. At the same time, this setting can facilitate the direct insertion of the limiting post 120 into the receiving cavity, making it easier for the operator to operate and reducing labor intensity.

[0042] It should be noted that the length of the insertion surface along the axial direction of the base 100 is less than the length of the limiting post 120 along the axial direction of the base 100. This arrangement can ensure the efficiency of the insertion of the limiting post 120. At the same time, when the connecting part 320 of the limiting post 120 located on the side of the buffer 200 is detachably connected to the connector 400, the connector 400 can be fixed.

[0043] Furthermore, the end of the connector 400 facing away from the punched part 300 abuts against the end face of the base 100 where the limiting post 120 is provided.

[0044] The end of the connector away from the punched part 300 abuts against the end face of the base 100 where the limiting post 120 is provided, so that the base 100 can stably transmit torque to the punched part 300 through the connector 400.

[0045] Furthermore, the buffer 200 has a columnar structure and is provided with through holes, which are filled with vibration damping material.

[0046] In this embodiment, the buffer 200 has a columnar structure, which is convenient for production. At the same time, the buffer 200 can be hollow with through holes. By adding damping material inside the through holes, the impact of excessive vibration on the base 100 during punch operation can be reduced.

[0047] Furthermore, the outer wall of the buffer 200 is provided with an external thread that is compatible with the internal thread.

[0048] The outer wall of the buffer 200 is provided with an external thread that is compatible with the internal thread, so that the buffer 200 and the connecting member 400 can be connected by threads.

[0049] Furthermore, the punched part 300 has a columnar structure, and the punched part 300 includes a contact part 310 and a connecting part 320, with the connecting part 320 disposed at the end of the contact part 310 facing the buffer part 200;

[0050] The connecting part 320 is used to detachably connect to the connector 400.

[0051] The punched part 300 has a columnar structure, which facilitates production and processing and reduces the labor intensity of workers. At the same time, the punched part 300 includes a contact part 310 and a connecting part 320. The contact part 310 is the drilling area of ​​the entire punched part 300. Its material is made of wear-resistant materials such as hard alloy steel to improve the hardness of the contact part 310.

[0052] The connecting part 320 is provided at the end of the contact part 310 facing the buffer member 200; the punched part 300 can be detachably connected to the connecting part 320 by means of threaded connection, riveting or other means.

[0053] Furthermore, the radial cross-sectional area of ​​the contact portion 310 is smaller than the radial cross-sectional area of ​​the connecting portion 320.

[0054] By making the radial cross-sectional area of ​​the contact portion 310 smaller than the radial cross-sectional area of ​​the connecting portion 320, the contact portion 310 can be formed into a "needle"-shaped structure, which facilitates drilling holes in the angle steel workpiece waiting to be processed.

[0055] Secondly, this embodiment also provides an angle steel punching machine, including the punch described above.

[0056] The installation steps for the punch are as follows:

[0057] S1: First, place the punched part 300 with its pointed end facing inward into the connector 400;

[0058] S2: Then place the buffer 200 into the connector 400;

[0059] S3: Then connect the connector 400, into which the punch 300 and buffer 200 are placed, to the punch base 100. Since the two are connected by threads, it is only necessary to tighten them.

[0060] S4: The assembly and placement of the punch is completed by placing the assembled detachable punch into the punch slot of the CNC angle steel punching machine.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
