Description

Technical Field

[0001] This application belongs to the technical field of stamping equipment, and particularly relates to a stamping equipment and its working method. Background Art

[0002] At present, with the development of technology, the requirements for the functions and accuracy of instruments are getting higher and higher, which leads to multiple circuits in the instruments, resulting in multiple wires that need to be fixed, providing room for the development of the fixed device structure. Since most production lines directly use machines to fix and install wires, there is a fixed component structure usually consisting of screws and a mounting seat adapted to the screws. The internal space of the mounting seat is adjusted by tightening and loosening the screws, and then the wires inside the mounting body are fixed.

[0003] Although the above structure can complete the fixation of wires, in the actual practical process, the screws need to be adjusted. The screws in the fixed component are prone to being over-rotated and falling off, thereby affecting normal use. To solve the problem of the screws being completely screwed out, there is an anti-dropping screw structure for a security adapter (Chinese Patent, Application No. 201711145965.X), which includes an adapter housing and an anti-dropping screw. The anti-dropping screw includes a screw head and a screw rod portion with an external thread. One end of the screw rod portion is integrally connected to the screw head, and the other end of the screw rod portion is provided with an end having a diameter larger than that of the screw rod portion, or several card slots are radially opened at the other end of the screw rod portion.

[0004] The above patent provides a solution for stamping the bottom to avoid the screws being completely screwed out. However, the specific stamping method is not described in detail. Since the overall size of the screws is small, during the stamping process, it is easy for the bolts to become thicker as a whole during the stamping process, affecting normal use. There is an urgent need for a new solution to solve the above problems. Summary of the Invention

[0005] One of the purposes of this application is to provide a stamping equipment in view of the deficiencies of the prior art. By setting a first processing space and a second processing space in the stamping die, only the set processing part is processed, preventing the overall expansion and thickening of the product.

[0006] To achieve the above purpose, the following technical solutions are adopted in this application: A stamping device, comprising a driving member, an upper die base and a lower die base, characterized in that a stamping die is mounted on the upper die base, and the stamping die is composed of a first die body installed in a second die body. A first processing space is formed in the first die body due to the height difference between the first cylinder and the second cylinder constituting the first die body, and a second processing space is formed in the second die body due to the height difference between the second cylinder and the second die body; in the height direction, the length of the first cylinder is less than the length of the second cylinder, and the length of the second cylinder is less than the length of the second die body.

[0007] As an improvement of the stamping device described in the present application, the stamping die has a bottom side close to the lower die base, and both the first processing space and the second processing space are opened towards the bottom side.

[0008] As an improvement of the stamping device described in the present application, a plurality of the second cylinders are provided, and the plurality of second cylinders are arranged around the first cylinder.

[0009] As an improvement of the stamping device described in the present application, the cross-section of the first cylinder is petal-shaped, and an assembly groove recessed towards the center direction is provided on the outer periphery of the first cylinder, and the assembly groove is used for the assembly of the second cylinder.

[0010] As an improvement of the stamping device described in the present application, the cross-section of the second cylinder is T-shaped, and the second cylinder includes a transverse cylinder and a vertical cylinder connected to each other, and the vertical cylinder is matched with the assembly groove.

[0011] As an improvement of the stamping device described in the present application, an installation through hole is provided in the second die body, and the first die body is fixedly installed in the installation through hole.

[0012] As an improvement of the stamping device described in the present application, the installation through hole includes a first through hole and a second through hole connected to each other. The first through hole is a circular through hole opened at the center of the second cylinder, and the second through hole is a T-shaped through hole provided outside the first through hole.

[0013] As an improvement of the stamping device described in the present application, the inner wall of the first through hole located in the second processing space is an expanding surface, and the expanding surface is recessed in a direction away from the center of the second cylinder.

[0014] As an improvement of the stamping device described in the present application, a plurality of the stamping dies are provided, and a plurality of bases are provided on the lower die base, and the stamping dies and the bases correspond to each other one by one.

[0015] The second object of the present application is to provide a working method of the above stamping device, comprising the following steps: Step 1: Place the assembled screw assembly on the lower die base; Step 2: The stamping die descends to process the screw assembly; Step 3: Take away the processed screw assembly and repeat the above steps; Among them, the screw assembly includes a screw and a mounting seat that are matingly installed, and the part of the bottom of the bolt of the screw that extends beyond the mounting seat is located inside the stamping die for processing.

[0016] The beneficial effect of this application is that: in the actual processing process, this application is used to only process the bottom of the bolt to make it larger, avoiding the situation where the whole bolt becomes thicker. There is a first processing space and a second processing space in the stamping die of the stamping equipment. The first processing space is used to prevent the excessive adhesion force between the part and the die after stamping, facilitating the stripping of the processed part. The second processing space is used to limit the processing stroke of the die and for buffering, avoiding the situation where the part overflows laterally due to the direct downward pressure of the die, resulting in the whole part becoming thicker.

For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] The following is combined with the attached Figures 1 to 7The specific implementation manners are used to further describe the present application in detail, but are not used to limit the present application. Implementation manner

[0030] The following combines the attached Figures 1 to 7 Describe Implementation manner 1 A stamping device includes a driving member 200, an upper die base 300 and a lower die base 400. A stamping die 100 is installed on the upper die base 300. There are multiple stamping dies 100. There are multiple bases 401 on the lower die base 400. The positions of the stamping dies 100 and the corresponding bases 401 are in one-to-one correspondence. During the manufacturing process, multiple parts can be processed at one time, improving work efficiency. It should be noted that the stamping dies 100 and the bases 401 only need to correspond in position and quantity, and do not need to be structurally matched. The function of the bases 401 is only to place and fix the parts to be processed.

[0031] Specifically, the stamping device further includes a fixing frame 500. The output end of the driving member 200 is connected to the upper die base 300. The fixing frame 500 is used to install the driving member 200 and the upper die base 300. A guiding column 600 is arranged between the upper die base 300 and the lower die base 400. The guiding column 600 is used to limit the movement direction of the upper die base 300 when it moves downward. The driving member 200 is a driving cylinder used to provide power for the up and down movement of the upper die base 300, thereby ensuring the normal operation of the stamping device.

[0032] Specifically, the stamping die 100 is composed of a first die body 1 installed in a second die body 2. The stamping die 100 has a bottom side 4 close to the lower die base 400.

[0033] Specifically, the first die body 1 includes a first column body 11 and a second column body 12 connected to each other. There are multiple second column bodies 12. The multiple second column bodies 12 are arranged around the first column body 11. In the height direction H, the length of the second column body 12 is greater than the length of the first column body 11. The height difference between the second column body 12 and the first column body 11 forms a first processing space 13 in the first die body 1. The first processing space 13 is opened towards the bottom side 4. The cross section of the first column body 11 is petal-shaped. An assembly groove 111 recessed towards the center direction is arranged on the outer periphery of the first column body 11. The assembly groove 111 is used for the assembly of the second column body 12. The cross section of the second column body 12 is T-shaped. The second column body 12 includes a transverse column body 121 and a vertical column body 122 connected to each other. The vertical column body 122 is matched with the assembly groove 111.

[0034] In this implementation manner, there are four second column bodies 12, and correspondingly, there are four assembly grooves 111. It can be understood that in some other technical solutions, the number of the second column bodies 12 and the shape of the first column body 11 can be set according to actual needs.

[0035] Specifically, the second die body 2 is provided with an installation through hole 21, and the first die body 1 is fixedly installed in the installation through hole 21. The installation through hole 21 includes a first through hole 211 and a second through hole 212 that are connected to each other. The first through hole 211 is a circular through hole provided at the center of the second cylinder 12, and the second through hole 212 is a T-shaped through hole provided outside the first through hole 211. The shape of the installation through hole 21 is integrally set according to the structure of the first die body 1. In the height direction H, the length of the second cylinder 12 is less than the length of the second die body 2, and the height difference between the second cylinder 12 and the second die body 2 forms a second processing space 3 within the second die body 2. The second processing space 3 opens towards the bottom side 4.

[0036] Preferably, the inner wall of the first through hole 211 located in the second processing space 3 is an expanding surface 2111, and the expanding surface 2111 is recessed in a direction away from the center of the second cylinder 12. The expanding surface 2111 enlarges the area of the second processing space 3. At the same time, the smoothly recessed expanding surface 2111 can reduce the friction between the components and the inner wall of the second processing space 3, facilitating demolding in the later stage.

[0037] In practical applications, the stamping die 100 is usually used to process assembled screw components. The bottom of the bolt in the screw component is stamped to make it larger, thereby preventing the complete screwing out of the screw. The second processing space 3 can first avoid the direct contact between the stamping die and the bottom of the bolt, preventing the situation where the bolt becomes thicker as a whole due to lateral expansion after being impacted, ensuring that the screw can be adjusted normally. Secondly, the second processing space 3 can control the downward stroke of the stamping die, increasing the accuracy of the stamping equipment. The first processing space 13 is located above the second processing space 3 in the height direction H. During the processing, the second cylinder 12 located outside the first processing space 13 is the main die body for processing the bottom of the bolt. The four second cylinders 12 have intervals, and the bottom of the bolt is processed into a petal shape. The part that expands under force is mainly concentrated in the part corresponding to the gap between two adjacent second cylinders 12. At the same time, due to the existence of the second processing space 3, it can prevent the diameter of the bolt from changing except for the set bottom part, ensuring that the screw component can rotate and be adjusted normally while preventing the complete screwing out of the screw.
