Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal stamping technology, and in particular to a springback structure. Background Technology
[0002] Cold stamping equipment is used for stamping metallic or non-metallic materials at room temperature. Its working principle is mainly based on applying pressure to the material using a die mounted on a press, causing separation or plastic deformation to obtain parts or components with the desired shape, size, and properties. The main characteristic of the cold stamping production process is that it relies on dies and stamping equipment to complete the processing.
[0003] Dies are prone to wear and tear after prolonged use and need to be replaced. However, existing dies are all locked with screws, which is inconvenient to maintain and does not allow for automatic springback disassembly. Improvements are needed. Utility Model Content
[0004] The purpose of this invention is to provide a spring-back structure to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A springback structure includes a lifting platform, a punch, a locking screw, a boss, and an inner slide plate. The lifting platform has an inner groove at the top center, and two symmetrical bosses are provided on one side of the inner groove. The inner slide plate is movably mounted on the front end of the bosses. A guide seat is provided on one side of the middle of the inner slide plate, and a guide groove is opened inside the guide seat. Both ends of the inner slide plate are provided with clamping arms. The punch is mounted on the top of the lifting platform.
[0007] Preferably, both sides of the boss are provided with clamping grooves, and the clamping arm slides inside the clamping grooves, and the front end of the clamping arm is provided with a slot.
[0008] Preferably, the bottom corner of the die is provided with a foot, and the foot is placed inside the clamping groove. A limit insert is provided on one side of the foot, and the limit insert is placed inside the slot.
[0009] Preferably, a pressing head is provided at the bottom center of the die, and the pressing head cooperates with the guide groove.
[0010] Preferably, the lower pressure head has a locking hole inside, and a locking screw is threaded to the side of the lifting platform, with one end of the locking screw passing through the lifting platform and connected to the inside of the locking hole.
[0011] Preferably, multiple sets of return springs are provided between the boss and the inner slide plate, a spring-loaded push plate is movably provided between the two guide seats, and a return spring is provided at the bottom of the spring-loaded push plate.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] This application improves the structure of the lifting platform by installing two sliding inner slide plates inside the platform. The outer side of each inner slide plate has a clamping arm, and the inner side has a guide seat. Four feet are provided at the bottom of the die. During installation, the die feet can directly press against the inside of the clamping groove. Simultaneously, the lower pressure head enters the guide seat, squeezing the springback push plate and pressing the inner slide plate to move to both sides. This causes the inner slide plate to move the clamping arm towards the feet, clamping and limiting them. Rotating the locking screw positions the lower pressure head, thus completing the die installation. During maintenance, simply release the locking screw; the springback push plate can then push the lower pressure head upwards, causing it to rise. The inner slide plate loses the clamping force of the lower pressure head and moves towards the center under the push of the return spring, causing the clamping arm to retract. The bottom of the die loses its limit and, pushed by the lower pressure head, can directly spring upwards. This allows for direct removal of the die, making maintenance simple and efficient.

[0020] This utility model provides, for example Figure 1-4 The spring-loaded structure shown includes a lifting platform 1, a punch 2, a locking screw 3, a boss 5, and an inner slide plate 7. The top center of the lifting platform 1 is provided with an inner groove 4. Two symmetrical bosses 5 are provided on one side of the inner groove 4. The inner slide plate 7 is movably mounted on the front end of the bosses 5. A guide seat 8 is provided on one side of the middle of the inner slide plate 7. A guide groove 14 is opened inside the guide seat 8. Both ends of the inner slide plate 7 are provided with clamping arms 9. The punch 2 is installed on the top of the lifting platform 1.
[0021] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a spring-loaded structure. Specifically, both sides of the boss 5 are provided with pressing grooves 6, and the pressing arm 9 slides inside the pressing grooves 6. The front end of the pressing arm 9 is provided with a slot.
[0022] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a springback structure. Specifically, the bottom corner of the punch 2 is provided with a foot 10, and the foot 10 is placed inside the clamping groove 6. A limiting insert 11 is provided on one side of the foot 10, and the limiting insert 11 is placed inside the slot. The foot 10 is made of metal. When the clamping arm 9 moves toward the foot 10, the limiting insert 11 on one side of the foot 10 can be inserted into the slot at the end of the clamping arm 9.
[0023] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a springback structure. Specifically, a pressing head 12 is provided at the bottom center of the punch 2, and the pressing head 12 cooperates with the guide groove 14.
[0024] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses a spring-loaded structure. Specifically, the lower pressure head 12 has a locking hole 13 inside, and the side of the lifting platform 1 is threaded with a locking screw 3. One end of the locking screw 3 passes through the lifting platform 1 and is connected to the inside of the locking hole 13. The locking screw 3 is a commercially available device known to those skilled in the art. Here, we are only using it without making any structural or functional improvements, and we will not elaborate further.
[0025] like Figure 1 , Figure 2 and Figure 3As shown, this utility model discloses a spring-loaded structure. Specifically, multiple sets of return springs 15 are provided between the boss 5 and the inner slide plate 7, and a spring-loaded push plate 16 is movably provided between the two guide seats 8. A return spring 2 is provided at the bottom of the spring-loaded push plate 16. The return springs 15 and 2 in this application are commercially available devices known to those skilled in the art. Here, we are only using them without making any structural or functional improvements, and we will not elaborate further.
[0026] like Figure 1 , Figure 2 and Figure 3 As shown, this application also discloses a metal stamping equipment, which includes a die mounting mechanism, and the die mounting mechanism is the springback structure disclosed in this application.
[0027] The working principle of this utility model is as follows: When installing the punch die 2, align the four bottom feet 10 of the punch die 2 with the inside of the clamping groove 6, and simultaneously press down the punch die 2, causing the lower pressure head 12 to enter the guide seat 8. The lower pressure head 12 presses the springback push plate 16 to the bottom, while the lower pressure head 12 slides inside the guide groove 14. The lower pressure head 12 moves towards both sides to squeeze the inner slide plate 7, causing the inner slide plate 7 to drive the clamping arm 9 to move towards the bottom feet 10. The clamping arm 9 clamps and limits the bottom feet 10. Then, rotate the locking screw 3. One end of the locking screw 3 is threaded into the inside of the lower pressure head 12, thereby positioning the lower pressure head 12 and completing the process. The installation of the die 2 is simple and efficient. When disassembling and maintaining the die 2, it is only necessary to release the limiting position of the locking screw 3. The spring-loaded push plate 16 can push the lower pressure head 12 upward, causing the lower pressure head 12 to rise. After the lower pressure head 12 rises, the inner slide plate 7 loses the squeezing force of the lower pressure head 12. Under the push of the return spring 15, it can move towards the center, thereby causing the four sets of clamping arms 9 to retract. The clamping arms 9 are separated from the bottom feet 10, and the bottom of the die 2 loses its limiting position. Under the push of the lower pressure head 12, it can directly spring upward. In this way, the die 2 can be directly removed. The maintenance of the die 2 is simple and efficient.
