Description

Technical Field

[0001] The present application relates to the technical field of stamping dies, and specifically discloses a clamping body progressive die. Background Art

[0002] The clamping body is one of the essential structural components in firearms. Usually, the clamping body is formed by stamping raw material plates.

[0003] Since the clamping body is not a flat component, during the stamping production process of the clamping body, it is usually necessary to perform multiple stamping formations on the clamping body, that is, it is necessary to use multiple sets of dies and stamping equipment to successively stamp and process the clamping body. This process also involves steps such as loading, unloading, and transferring semi-finished components between different stations. Not only is the equipment cost relatively high, but the overall processing cycle is long, the production efficiency is low, and the finished product quality of the clamping body is affected by each stamping equipment, making it difficult to control the finished product quality.

[0004] A progressive die refers to a cold stamping die that uses a strip-shaped stamping raw material during one stamping stroke of a press and simultaneously completes multiple stamping processes at several different stations on a set of dies. Each time the die completes a stamping, the strip moves a fixed distance until the product is completed. Although progressive dies have been widely used in stamping processing, there are currently no related dies that can be used for the production and processing of clamping bodies. Therefore, in view of this, the inventor provides a clamping body progressive die to solve the above problems. Summary of the Utility Model

[0005] The purpose of the present utility model is to solve the problem that during the traditional production process of clamping bodies, it is necessary to perform stamping formations on multiple pieces of equipment, resulting in relatively high equipment costs, long processing cycles, and low production efficiency.

[0006] To achieve the above purpose, the basic solution of the present utility model provides a clamping body progressive die, including:

[0007] An upper die assembly and a lower die assembly, which are respectively arranged on the slider and the table surface of a press;

[0008] A support assembly for supporting the upper die assembly and the lower die assembly;

[0009] A number of forming blocks, which are successively arranged along the material flow direction and are driven by the upper die assembly to perform vertical reciprocating movements, respectively used for stamping and forming in each stamping step of the clamping body.

[0010] Further, the forming blocks include a positioning forming block for positioning the end of the material, an end face forming block for forming the end faces of the two ends of the material, a punching and cutting forming block for punching and cutting adjacent materials, a punching forming block for punching the two ends of the punched material, a recess forming block for forming the recesses of the material after punching, an extrusion forming block for extruding the side of the material after recess forming to form a bent end face structure of the clamping body, and a cutting forming block for cutting the formed clamping body and the end of the material.

[0011] Further, the upper die assembly includes an upper die base, an upper back plate, an upper backing plate, and an upper clamping plate arranged in sequence from top to bottom. The upper die base is connected to the slider of the press. The lower die assembly includes a stripping back plate, a stripping plate, a lower template, a lower backing plate, and a lower die base arranged in sequence from top to bottom and located below the upper die assembly. The support assembly includes lower feet provided at the bottom of the lower die base.

[0012] Further, the forming blocks are respectively arranged on the upper clamping plate in sequence along the material flow direction and are driven by the upper die base, the upper backing plate, and the upper clamping plate to perform vertical reciprocating motion.

[0013] Further, a support die adapted to the straight part of the clamping body and a bottom die adapted to the recess of the clamping body are provided on the lower template.

[0014] Further, it further includes symmetrically arranged wedge blocks. The extrusion forming blocks are two symmetrically arranged ones, and the side walls of the two extrusion forming blocks are respectively slidably connected to the inclined surfaces of the wedge blocks.

[0015] Further, a plurality of guide rods are also provided between the upper die assembly and the lower die assembly.

[0016] The principle and effect of this solution are as follows:

[0017] Compared with the prior art, the utility model has multiple forming blocks arranged in sequence along the material flow direction. Thus, under the action of the press, each forming block is driven to perform vertical reciprocating motion synchronously. And when the forming block reciprocates once, the feeder drives the raw material plate to move forward once, and the moving distance is the synchronous distance between adjacent two clamping bodies. Then, multiple stamping processes at different stations can be completed simultaneously by a set of dies, reducing the quality risk generated in the production of multiple processes, improving the production efficiency, saving costs, and solving the problems in the traditional production process of clamping bodies, such as high equipment cost, long processing cycle, and low production efficiency caused by stamping and forming on multiple devices.

[0025] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following, in combination with the drawings and preferred embodiments, details the specific implementation manners, structures, features, and their effects of the present invention as follows.

[0026] The reference numerals in the accompanying drawings of the specification include: upper die holder 1, upper back plate 2, upper backing plate 3, upper clamping plate 4, stripping back plate 5, stripping plate 6, lower template 7, lower backing plate 8, lower die holder 9, lower pad feet 10, material 11, positioning forming block 12, end face forming block 13, bottom die 14, recess forming block 15, support die 16, extrusion forming block 17, wedge block 18.

[0027] A clamp body progressive die, for example in the embodiment Figure 1As shown in the figure, it includes an upper die assembly, a lower die assembly, a support assembly, and several forming blocks. The upper die assembly and the lower die assembly are respectively arranged on the slider and the table of the press. There are several guide rods between the upper die assembly and the lower die assembly for sliding guidance. Among them, the upper die assembly includes an upper die base 1, an upper back plate 2, an upper backing plate 3, and an upper clamping plate 4 arranged in sequence from top to bottom. The upper die base 1, the upper back plate 2, the upper backing plate 3, and the upper clamping plate 4 are detachably connected to each other by a plurality of bolts. The lower die assembly includes a stripping back plate 5, a stripping plate 6, a lower template 7, a lower backing plate 8, and a lower die base 9 which are arranged in sequence from top to bottom and below the upper die assembly. The stripping back plate 5, the stripping plate 6, the lower template 7, the lower backing plate 8, and the lower die base 9 are detachably connected to each other by a plurality of bolts. The support assembly includes lower feet 10 arranged at the bottom of the lower die base 9.

[0028] The material 11 for continuous stamping production moves along the table of the press driven by a feeder. The forming blocks are arranged on the upper clamping plate 4 and move downward driven by the slider of the press to stamp and form the material 11 on the table of the press. A plurality of forming blocks for stamping and forming each stage of the clamp body are arranged along the moving direction of the material 11. For example, Figure 2 As shown in the figure, it includes a positioning forming block 12 for positioning the end of the material 11, an end face forming block 13 for forming the end faces of the clamp body at both ends of the material 11, a middle punching forming block for symmetrically punching the middle of the material 11, a punching and cutting forming block for punching and cutting adjacent materials 11, an end punching forming block for punching the ends of the material 11 after punching, a concave part forming block 15 for forming the concave part of the clamp body of the material 11 after punching, an extrusion forming block 17 for extruding the side of the material 11 after concave part forming to form a bent end face structure of the clamp body, and a cutting and forming block for cutting the formed clamp body from the end of the material 11.

[0029] As Figure 3 and Figure 4 As shown in the figure, the stamping and forming of the clamp body mainly involves the forming of the concave part at the bottom and the forming of the bent end face at the end. A support die 16 adapted to the straight part of the clamp body and a bottom die 14 adapted to the concave part of the clamp body are arranged on the lower template 7. Wedge blocks 18 are symmetrically arranged on the stripping back plate 5. The extrusion forming blocks 17 are two symmetrically arranged, and the side walls of the two extrusion forming blocks 17 are respectively slidably connected to the inclined surfaces of the wedge blocks 18.

[0030] In this embodiment, the material 11 moves along the table of the press driven by a feeder and successively passes through each forming block for stamping and forming in each step. For example, Figure 5 and Figure 6As shown, the plate-shaped material 11 moves along the tabletop of the press driven by the feeder. First, the positioning and forming block 12 punches both ends of it. The shapes of the positioning holes are formed at both ends of the plate-shaped material 11 to facilitate the positioning of subsequent stamping steps. The material 11 with positioning holes moves to the lower part of the middle punching and forming block. The middle punching and forming block punches the middle of the material 11. The material 11 after middle punching moves to the lower part of the end face forming block 13. The shape of the end face forming block 13 is adapted to the shape of the gap after stamping at the end of the material 11 as shown in Figure 5 As shown. The end face forming block 13 punches both ends of the material 11 to form the planar shape at both ends of the clamp body. Then the material 11 moves to the punching and cutting forming block. The punching and cutting forming block punches and cuts two adjacent clamp bodies, so that individual clamp bodies are formed on the material 11 plate. The material 11 after punching and cutting moves to the end punching and forming block to punch both ends of each individual clamp body. After end punching, it enters the lower part of the concave part forming block 15. As shown in Figures 3 to 6 As shown, the concave part forming block 15 cooperates with the bottom die 14 on the lower template 7 to punch the bottom of the individual clamp body into a concave shape. The individual clamp body after concave part forming enters the lower part of the extrusion forming block 17. The extrusion forming block 17 cooperates with the wedge block 18 to bend the end of the clamp body inward, so that the individual clamp body forms a bent end face structure. Then the individual clamp body cuts off between the end of the individual clamp body and the raw material plate through the cutting and forming block, and the completed clamp product can be obtained.

[0031] During this process, the slider of the press drives each forming block to perform a vertical reciprocating motion synchronously. And each time the forming block reciprocates, the feeder drives the raw material plate to move forward once, and the moving distance is the synchronous distance between two adjacent clamp bodies. Thus, multiple stamping processes at different stations can be completed simultaneously by a set of dies, reducing the quality risks generated by multiple processes, improving the production efficiency, and saving costs.

[0032] The above is only a preferred embodiment of the present invention and does not impose any form of limitation on the present invention. Although the present invention has been disclosed as above with the preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to it as equivalent embodiments within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
