[0002] Small metal crafts are exquisite products with high aesthetic value. The application of progressive die-stamping is crucial in their production process. Through efficient forming technology and precise dimensional control, it ensures the accuracy and perfection of every detail, thus creating breathtaking works of art.

[0003] A multi-station continuous stamping die, such as the one disclosed in CN215090140U, includes a fixed die and a movable die. The fixed die includes a worktable with a workpiece groove at the center of its top. Limiting posts are fixedly connected to both sides of the top of the worktable. The movable die includes a support frame with a fixed platform fixedly connected to its top. A hydraulic cylinder is fixedly installed inside the fixed platform. A pressure plate is slidably connected to the middle of the limiting posts, and the top of the pressure plate is fixedly connected to the output end of the hydraulic cylinder. This utility model provides a multi-station continuous stamping die that is more convenient and quick to disassemble, replace, and operate, and has good flexibility. By setting a guide conveyor belt, it effectively avoids workpiece vibration and displacement during stamping, improving the stability of the conveying process. By setting a support plate and support bolts, it provides auxiliary support for the workpiece, reducing deformation of unnecessary stamping parts during stamping.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: Please refer to Figure 1 - Figure 6 This utility model provides the following technical solution: A multi-station continuous stamping die for small metal crafts, including a base 1, a slide rail 2 fixedly installed on the upper inner side of the base 1, a slider 3 slidably installed on the upper end of the slide rail 2, a moving plate 4 fixedly installed on the upper end of the slider 3, a cylinder 5 fixedly installed on the outer side of the base 1, the moving plate 4 is moved on the slide groove by the cylinder 5; a guide sleeve 6 is fixedly installed on the upper end of the moving plate 4, a cylinder 8 is fixedly installed on the upper end of the moving plate 4, a connecting plate 9 is fixedly installed on the upper end of the cylinder 8, a step feeding structure is provided inside the base 1, the products are fed one by one by the step feeding structure, and an auxiliary fixing structure is provided on the upper end of the base 1, the products are fixed by the auxiliary fixing structure to facilitate processing.

[0020] The step-feeding structure is equipped with guide posts 7, which are slidably installed inside the guide sleeve 6. A push plate 10 is fixedly installed on the upper end of the connecting plate 9, and a clamping plate 11 is fixedly installed on the upper end of the push plate 10. The output end of cylinder 1 5 passes through the outer side of the base 1 and extends into the interior of the moving plate 4. Cylinder 1 5 and the moving plate 4 are fixedly connected. Two identical cylinders 2 8 are provided. Four identical sets of guide posts 7 and guide sleeves 6 are provided, and the guide posts 7 and guide sleeves 6 are symmetrically distributed about the central axis of the moving plate 4. The guide posts 7 and the connecting plate 9 are threadedly connected. When the product material is placed between the two outermost clamping blocks 16 of the fixed frame 12, cylinder 1 5 is activated, driving the slider 3 at the lower end of the moving plate 4 to move on the slide rail 2 through its thrust. After reaching the designated position, cylinder 2 8... The moving connecting plate 9 rises, pushing the push plate 10 and the clamping plate 11 to rise together, so that the clamping groove in the clamping plate 11 can firmly clamp the product material, thereby lifting the product. Then, the cylinder 5 retracts, the moving plate 4 moves again, the position of the push plate 10 changes, and the clamping plate 11 carries the product material to the next set of clamping blocks 16. After reaching the position, the cylinder 8 retracts, and the push plate 10 and the clamping plate 11 descend. The guide columns 7 arranged around the perimeter provide a buffering effect when they move inside the guide sleeve 6, preventing the cylinder 8 from retracting too quickly, and ensuring that the product material is accurately delivered to the next set of clamping blocks 16. This operation is repeated until the product is successfully delivered. During the processing, the ramp design between the clamping plates 11 can discharge the debris generated during processing as it moves, which is convenient for quick collection and has high practicality.

[0021] Example 2: Based on Example 1, an auxiliary fixing structure is also disclosed, the specific structure of which is as follows: Figure 5 - Figure 6 As shown: The auxiliary fixing structure is provided with a fixing frame 12, which is fixedly installed on the upper end of the base 1. A cylinder 13 is fixedly installed on the upper end of the fixing frame 12. A fixing plate 14 is fixedly installed on the output end of the cylinder 13. A pressing mold 15 is fixedly installed on the lower end of the fixing plate 14. The output end of the cylinder 13 passes through the upper end of the fixing frame 12 and extends into the interior of the fixing plate 14. Four identical pressing molds 15 are provided and are equidistantly distributed on the lower end of the fixing plate 14.

[0022] A locking block 16 is fixedly installed on the outer side of the fixed frame 12, and a buffer column 17 is fixedly installed on the lower outer side of the fixed plate 14. A buffer groove 18 is opened at the upper end of the locking block 16, and a discharge plate 19 is fixedly installed on the outer side of the fixed frame 12. The locking blocks 16 are evenly distributed on both sides of the fixed frame 12. The buffer column 17 and the buffer groove 18 are nested together. A rectangular groove is opened at the upper end of the discharge plate 19. The locking plates 11 are evenly distributed on the upper end of the push plate 10. A ramp is provided between the locking plates 11, and the angle of the ramp is 10°-30°. A locking groove is opened at the upper end of the locking plate 11, and the locking plate 11 is adapted to the rectangular groove. When the step-feeding structure is started, the cylinder 3 13 is started. Through the push of the cylinder 3 13, the fixed plate 14 begins to move. The fixed plate 14 drives the lower pressing mold 15 to process the product raw material. At the same time, the locking blocks 16 on both sides will firmly fix the product raw material. Each pressing mold 15 applies different degrees of processing as needed. During processing in the pressing die 15, the buffer pillars 17 on both sides automatically embed into the buffer grooves 18 to provide buffering for the pressing die 15, preventing excessive downward pressure from deforming the product material and avoiding defects in subsequent processing. After processing is completed, the step-pitch feeding structure will transfer the product to the discharge plate 19 for easy collection by staff, greatly improving practicality.
