[0002] A die is various molds and tools used in industrial production to obtain required products by means of injection molding, blow molding, extrusion, die casting, forging, smelting, stamping, etc. In short, a die is a tool for making formed articles. This tool is composed of various parts, and different dies are composed of different parts. It mainly realizes the processing of the outer shape of articles by changing the physical state of the formed material. It is known as the "mother of industry". When processing a strip, a stamping die is often used to realize the blanking process of the strip. The blanking process of the strip is often a continuous processing method. After blanking at one position, blanking processing needs to be carried out at another position at a certain distance.

[0003] In the existing continuous blanking process of a stamping die, the strip is driven to move backward by means of manual feeding or feeding by a feeder. When manual feeding is used, it is necessary to visually compare the top positioning holes on the strip with the corresponding positioning posts on the die for positioning. Not only is the feeding efficiency low, but also the feeding accuracy cannot be guaranteed in case of poor light. When feeding by a feeder, there is a problem that the feeding time of the feeder is inaccurate, resulting in the retreat of the strip, which affects the quality of strip processing. Therefore, it is necessary to study a new technical solution to solve the above problems. Summary of the Utility Model

[0027] Please refer to Figures 1 to 3 as shown, which shows the specific structure of the preferred embodiment of the present utility model, including a base 10, an anti-retreat rod 20 and an elastic member 30.

[0028] The base 10 is arranged on an external mold and is located beside the external tape 40; in this embodiment, an upper-end open hinge groove 101 is arranged on the base 10. The hinge groove 101 is arranged in a cylindrical shape extending horizontally, the hinge groove 101 penetrates through the left and right side walls of the base 10, and the width of the upper-end opening of the hinge groove 101 is smaller than the diameter of the hinge groove 101, which is used to prevent the anti-retreat rod 20 from falling off from the upper-end opening of the hinge groove 101. A connecting part 11 is integrally formed on the base 10 in the direction towards the tape 40, and a first mounting hole 102 is opened on the connecting part 11.

[0029] One end of the anti-retreat rod 20 is hinged to the base 10, the other end of the anti-retreat rod 20 moves back and forth beside the tape 40, and an anti-retreat part 21 that cooperates with the positioning groove 401 of the tape 40 is formed on the anti-retreat rod 20; through the cooperation between the anti-retreat part 21 and the positioning groove 401, the feeding process of the tape 40 is positioned. In this embodiment, a hinge part 22 that cooperates with the hinge groove 101 is arranged on the anti-retreat rod 20; one end of the anti-retreat rod 20 is hinged to the base 10 through the cooperation between the hinge part 22 and the hinge groove 101. The hinge part 22 is arranged in a cylindrical shape that cooperates with the hinge groove 101, so that the hinge part 22 can be inserted into the hinge groove 101 from one side of the hinge groove 101, making the assembly process more convenient. A second mounting hole 201 is opened on the anti-retreat rod 20. The anti-retreat part 21 extends vertically, and the vertically extending anti-retreat part 21 is used to prevent the situation that the anti-retreat part 21 and the positioning groove 401 are vertically misaligned due to the change in the height of the tape 40, ensuring the stability of the positioning process with the tape 40.

[0030] On one side of the anti-retreat part 21 facing away from the moving direction of the strip 40, a guiding part 211 that cooperates with the positioning groove 401 of the strip 40 is integrally formed. On one side of the anti-retreat part 21 facing the moving direction of the strip 40, a right-angle part 212 that cooperates with the positioning groove 401 of the strip 40 is integrally formed. The guiding part 211 is used to, after stamping is completed, when the strip continues to be fed backward, move out of the positioning groove 401 outward through the cooperation between the guiding part 211 and the positioning groove 401, so as to meet the process of the strip continuing to be fed backward. The cooperation between the right-angle part 212 and the positioning groove 401 is used to further prevent the strip 40 from retreating backward.

[0031] The elastic member 30 is clamped between the anti-retreat rod 20 and the base 10 and urges the other end of the anti-retreat rod 20 to move and reset toward the external strip 40. The elastic member 30 urges the anti-retreat part 21 to complete the cooperation with the positioning groove 401. In this embodiment, the two ends of the elastic member 30 are respectively fixedly installed in the first installation hole 102 and the second installation hole 201 and urge the anti-retreat rod 20 to reset. The elastic member is a spring. At the same time, the elastic member can also be other elastic components, which is not limited thereto.

[0032] The design focus of the present utility model lies in that: the other end of the anti-retreat rod moves back and forth beside the strip, and an anti-retreat part that cooperates with the positioning groove of the strip is formed on the anti-retreat rod; and it is cooperated with the elastic member that is clamped between the anti-retreat rod and the base and urges the other end of the anti-retreat rod to move and reset toward the external strip; so that during the continuous processing of the strip, when the strip is being fed, when the next positioning groove moves to the position of the anti-retreat rod, the elastic member urges the anti-retreat rod to move into the positioning groove, thereby completing the feeding and positioning process of the strip, which not only ensures the feeding accuracy, but also does not require human eye observation, the feeding efficiency is higher, and at the same time, the situation of the strip retreating due to the unstable feeding time of the feeder will not occur, ensuring the processing quality of the strip.

[0033] The above is only a preferred embodiment of the present utility model, and does not impose any limitation on the technical scope of the present utility model. Therefore, any minor modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model still belong to the scope of the technical solution of the present utility model.
