[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] like Figure 1 and Figure 2 As shown, a mechanism for stamping and locking with a steel stamp includes a frame 12, and the mechanism for stamping and locking with a steel stamp further includes:

[0025] Motor 2, which is fixedly mounted on frame 12, has its output shaft rotatably connected to belt 4 and pulley 3;

[0026] Cam 14 is rotatably connected to frame 12 via a wheel axle. Belt 4 is fitted on the belt pulley 3 and cam 14. Cam 14 rotates synchronously with belt pulley 3 via belt 4.

[0027] The swing arm 8 is hingedly mounted on the frame 12. One end of the swing arm 8 is connected to a bearing 15 via a connecting rod 5. The bearing 15 is in rolling contact with the outer peripheral surface of the cam 14.

[0028] Push rod 9 is connected to the swing arm 8, and the lower end of push rod 9 is connected to a stamped mold 10;

[0029] The fixture 13 is mounted on the frame 12 and positioned directly below the stamping mold 10 for positioning the workpiece 11.

[0030] The pull rod 6 is hinged to the side of the swing arm 8 near the push rod 9, and one end of the pull rod 6 is connected to a tension spring 7, which is fixedly mounted on the frame 12.

[0031] The steel stamping mold 10 and the lower end of the push rod 9 are detachably connected.

[0032] The clamp 13 is a detachable clamp 13, which is connected to the frame 12 by bolts.

[0033] The surface of the cam 14 has a non-uniform diameter structure, and the lever arm of the tension spring 7 is adjusted by rotating the cam 14.

[0034] It also includes a material conveying platform, which is mounted on the frame 12 and located on one side of the fixture 13, for conveying the workpiece 11 to the positioning position of the fixture 13.

[0035] In operation, motor 2 drives belt gear 3 via belt 4 for continuous motion, while bearing 15 moves in a circular motion along the surface of cam 14. When bearing 15 reaches the highest point of cam 14, swing arm 8, along with push rod 9, presses down, causing fixture 13 and stamping die 10 to complete the stamping action on workpiece 11, simultaneously tightening spring 7 and extending it. When bearing 15 moves away from the highest point of cam 14, pull rod 6, during the contraction of spring 7, causes push rod 9, along with stamping die 10, to lift. Simultaneously, the feeding platform moves horizontally, allowing the next workpiece to reach its position, thus automating the product process. The detachable fixture 13 allows for the replacement of different stamping dies 10 according to different stamping processes, achieving product diversity and reducing production costs. The rotation of cam 14 adjusts the spring arm of tension spring 7, achieving adjustable stamping pressure and high precision.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
