[0022] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model. Example

[0023] A rapid stamping die for metal sheets includes a base 1, a cylinder seat 2, and a bracket 4. The cylinder seat 2 and the bracket 4 are respectively arranged parallel to each other on the base 1. A cylinder 4 is provided inside the cylinder seat 2, and the cylinder rod of the cylinder 4 is parallel to the base 1 and faces the bracket 4. A punch linear actuator 8 is provided on the upper part of the bracket 4. The telescopic rod of the punch linear actuator 8 is perpendicular to the base 1, and the end of the telescopic rod of the punch linear actuator 8 is provided with a thread, and a first limit 11 is provided above the thread.

[0024] The cylinder rod end of the cylinder 4 is provided with a cylinder rod connecting end 5, the cylinder rod connecting end 5 is provided with external threads, and the end face of the cylinder rod connecting end 5 is provided with a positioning groove 5-1.

[0025] The punch 7 includes a punch center post 7-1, a punch body 7-2, a punch limiter 7-3, and a punch positioning post 7-4; the punch center post 7-1 has a punch body 7-2 for stamping metal sheet A at the front; the punch center post 7-1 has a punch limiter 7-3 and a punch positioning post 7-4 at the rear.

[0026] The threaded cover 6 has a through hole on its surface. The punch 7 is fixed to the cylinder rod connecting end 5 through the threaded cover 6. The punch positioning post 7-4 is embedded in the positioning groove 5-1. The punch limiter 7-3 forms a limit with the inner side of the threaded cover 6.

[0027] The stamping base 9 has a connecting hole at the rear end and a groove on the end face of the front end of the stamping base 9 to avoid the stamping and bending part of the metal sheet A.

[0028] The end of the telescopic rod of the punch linear actuator 8 passes through the connecting hole at the rear end of the stamping seat 9 and is screwed onto the thread of the telescopic rod end of the punch linear actuator 8 by the nut 12, thereby realizing the connection of the stamping seat 9 to the end of the telescopic rod of the punch linear actuator 8.

[0029] On the base 1, a positioning buffer seat 10 is provided directly below the telescopic rod of the stamping linear actuator 8.

[0030] A metal sheet mounting bracket 13 is also provided on the base 1. The metal sheet mounting bracket 13 is located between the cylinder seat 2 and the bracket 4. The metal sheet mounting bracket 13 includes a central crossbeam for supporting the metal sheet A, and columns on both sides of the crossbeam. The columns on both sides are provided with grooves. The two ends of the demolding piece 15 are embedded in the grooves of the columns on both sides of the metal sheet mounting bracket 13. After placing several shims 16 on the front and rear sides of the demolding piece 15, the demolding piece 15 is fixed to the columns on both sides of the metal sheet mounting bracket 13 by bolts 17.

[0031] The metal sheet mounting bracket 13 has elastic clips 14 on both sides of the crossbeam for locking the metal sheet A.

[0032] Metal sheet A and demolding sheet 15 are selected with the same thickness, and the end faces of metal sheet A, demolding sheet 15 and the front end of stamping seat 9 are on the same plane.

[0033] How to use:

[0034] Stamping process: The metal sheet A is placed on the crossbeam of the metal sheet mounting bracket 13. Both ends of the metal sheet A are inserted into the elastic clips 14. The telescopic rod of the punch linear actuator 8 extends, so that the front end face of the stamping seat 9 is located behind the metal sheet A. The cylinder rod of the cylinder 4 extends, so that the punch body 7-2 of the punch 7 stamps the surface of the metal sheet A. The bent part of the metal sheet A enters the groove of the stamping seat 9, thus realizing the stamping process of the metal sheet A. Then the cylinder rod of the cylinder 4 resets, and the telescopic rod of the punch linear actuator 8 retracts.

[0035] Demolding process: After the stamping process is completed, there are two demolding scenarios.

[0036] Scenario 1: As the punch linear actuator 8 moves along the telescopic rod of the punch, the two ends of the metal sheet A remain on the crossbeam of the metal sheet mounting bracket 13 due to being fixed by the elastic clip 14. At this time, the metal sheet A can be directly removed from the elastic clip 14.

[0037] Scenario 2: The stamping base 9 moves upward with the stamped metal sheet A. The two ends of the metal sheet A are released from the fixation of the elastic clip 14. At this time, since the demolding piece 15 is tangent to the front end face of the stamping base 9, the demolding piece 15 squeezes down the metal sheet A located at the front end face of the stamping base 9 during the upward movement of the stamping base 9.

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
