Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, specifically relating to a device for rapidly pressing, cutting, punching, and extracting materials. Background Technology

[0002] In spot welding experiments, we sometimes encounter situations where a flux sheet of a specific shape needs to be placed in the interlayer of the material being welded to ensure weld strength and appearance. This invention allows for the rapid forming, blanking, and extraction of the flux sheet via manual punching. Utility Model Content

[0003] This invention addresses the shortcomings of existing technologies by providing a device for rapidly pressing, cutting, punching, and extracting flux. This device allows for direct and rapid manual punching of flux sheets of specific shapes required during welding experiments. Furthermore, the entire device is compact and convenient. If other shapes of flux sheets are desired during the experiment, the punch and die can be directly replaced, saving costs and increasing speed.

[0004] This utility model is achieved through the following technical solution:

[0005] An apparatus for rapidly pressing, cutting, punching, and extracting materials, comprising an upper die portion and a lower die portion;

[0006] The upper mold portion, from top to bottom, includes an upper template, an upper pad, an upper mold base, and a guide plate. A punch preload guide block is vertically slidably embedded in the upper mold base and the guide plate. A punch is vertically slidably embedded in the punch preload guide block, and the top of the punch is fixedly connected to the upper pad. A spring is provided on the top of the punch preload guide block, and a limiting protrusion is provided on the top side wall of the punch preload guide block. A limiting step corresponding to the limiting protrusion is provided at the top of the mounting channel of the punch preload guide block on the guide plate. The limiting protrusion rests on the limiting step, restricting the downward stop position of the punch preload guide block. Thus, the spring provides downward preload force to the punch preload guide block. A scrap material pressing block is also vertically slidably embedded in the guide plate. A top spring is provided on the top of the scrap material pressing block. The scrap material pressing block is located on the rear side of the punch's discharge direction, and the scrap material strip that has been punched is pressed down by the scrap material pressing block.

[0007] The lower die part includes, from bottom to top, a base plate, a lower die ejection block, and a concave template; a concave module is provided on the concave template at the position corresponding to the punch, and a material discharge channel connected to the material discharge port of the concave module is provided on the lower die ejection block.

[0008] An upper cutter is also provided on the side wall of the guide plate on the discharge side, and a lower cutter is provided on the concave template accordingly.

[0009] In the above technical solution, guide pillars are vertically arranged on the guide pillar plate, with the bottom of the guide pillars extending out of the bottom surface of the guide pillar plate. Corresponding guide pillar insertion holes are provided on the lower mold part. In this way, when the mold is closed, the bottom of the guide pillar can be inserted into the corresponding guide pillar insertion hole of the lower mold part, which plays a positioning and guiding role, so that the stamping position of the upper and lower molds is accurate.

[0010] In the above technical solution, there are two guide pillars, which are distributed on both sides of the guide pillar plate.

[0011] In the above technical solution, a positioning baffle is provided on the discharge side of the bottom plate to position the material belt and ensure that the conveyed material belt has a consistent length.

[0012] In the above technical solution, a material conveying guide baffle and a guide column are provided on the concave template. There are two material conveying guide baffles, which are symmetrically arranged on both sides of the material belt. There are also two guide columns, which are symmetrically arranged on both sides of the material belt. The material conveying guide baffle is located on the feeding side of the concave template, and the guide column is located on the discharging side of the concave template.

[0013] In the above technical solution, a tie rod is provided on the upper template of the upper mold part, which is used to fix the tie rod or the upper template of the upper mold part to the hand press, and the bottom plate of the lower mold part is connected to the locking block of the lower half of the hand press.

[0014] Advantages and beneficial effects of this utility model:

[0015] During operation, the strip is conveyed forward along the strip conveyor guide baffle, passing the guide post and stopping at the positioning baffle. Then, the press press closes the mold. During the mold closing process, the punch pre-press guide block stably presses the strip onto the concave die. Then, the punch punches out from the punch pre-press guide block, punching off the material on the strip to form a sheet of the required shape. The punched sheet is discharged along the material discharge channel of the lower die ejector block. At the same time, during the punching process, the scrap block holds the scrap strip in place and cuts it off by the upper and lower cutters.

[0016] This utility model is more compact and quicker to install and disassemble than traditional stamping. It allows for direct replacement of the punch and die to change the required material shape, resulting in low changeover costs. At the same time, the material is discharged quickly and can be directly extracted. Attached Figure Description
