Description

Technical Field

[0001] The present application relates to the technical field of stamping dies, and specifically discloses a continuous die for the left wall of a magazine. Background Art

[0002] A magazine is one of the essential structural components of a firearm. Generally, a magazine consists of a left wall and a right wall, and the left wall and the right wall are fixed by bolts to form a cavity for placing bullets. Both the left wall and the right wall of the magazine are formed by stamping raw material plates.

[0003] Taking the left wall of the magazine as an example, since the left wall of the magazine is not a flat component, during the stamping production process of the left wall of the magazine, it is usually necessary to perform multiple stamping operations on the left wall of the magazine, that is, multiple sets of dies and stamping equipment are required to perform stamping processing on the left wall of the magazine in sequence. This process also involves steps such as loading, unloading, and transferring semi-finished parts 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 quality of the finished product of the left wall of the magazine is affected by each stamping equipment, making it difficult to control the quality of the finished product.

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

[0005] The purpose of the present utility model is to solve the problem that during the production process of the traditional left wall of a magazine, stamping forming needs to be carried out on multiple devices, 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 continuous die for the left wall of a magazine, including:

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

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

[0009] A plurality of forming blocks, which are sequentially arranged along the material flow direction and are driven by the upper die assembly to perform vertical reciprocating movements, so as to respectively perform stamping forming in each stamping step of the left wall of the magazine.

[0010] Further, the forming block includes a positioning forming block for positioning the end of the material, a first forming block for stamping and forming the inner wall of the edge and the bottom of the left wall of the magazine respectively, a second forming block for stamping and forming the two ends of the edge of the left wall of the magazine respectively, a concave surface forming block for stamping and forming the concave surface in the middle of the left wall of the magazine, an extrusion forming block for stamping and forming the peripheral end of the left wall of the magazine, a third forming block for stamping and forming the outer wall of the edge of the left wall of the magazine, and a cutting forming block for cutting the formed left wall of the magazine and the end of the material.

[0011] Further, the upper die assembly includes an upper back plate, an upper die base, an upper padding plate, and an upper clamping plate which are arranged in sequence from top to bottom.

[0012] Further, the lower die assembly includes a stripping back plate, a stripping plate, a lower template, a lower padding plate, and a lower die base which are arranged in sequence from top to bottom and are located below the upper die assembly.

[0013] Further, the supporting assembly includes a lower foot pad and a lower supporting plate which are arranged in sequence from top to bottom and are located below the lower die assembly, and the top of the lower foot pad is connected to the lower die base.

[0014] Further, a plurality of guide rods are also arranged between the upper die assembly and the lower die assembly.

[0015] Further, guide wheels for guiding the material flow are symmetrically arranged in front of the positioning forming block along the material flow direction.

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

[0017] Compared with the prior art, in the present utility model, a plurality of forming blocks are arranged in sequence along the material flow direction. Thus, under the action of a press, each forming block is driven 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 left walls of the magazine. In this way, multiple stamping processes at different stations can be completed simultaneously by a set of dies, reducing the quality risks generated in the production of multiple processes, improving the production efficiency, saving costs, and solving the problems in the production process of the traditional left wall of the magazine, such as the need for stamping and forming on multiple devices, resulting in high equipment costs, long processing cycles, and low production efficiency.

[0024] A continuous die for the left wall of a magazine, as shown in the embodiments Figure 1 as follows: 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 surface 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 back plate 1, an upper die holder 2, an upper backing plate 3 and an upper clamping plate 4 arranged in sequence from top to bottom. The upper die holder 2 is connected to the slider of the press. The upper back plate 1, the upper die holder 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 holder 9 which are arranged in sequence from top to bottom 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 holder 9 are detachably connected to each other by a plurality of bolts. The support assembly includes a lower foot 10 and a lower support plate 11 which are arranged in sequence from top to bottom below the lower die assembly.

[0025] The material 12 for continuous stamping production moves along the table surface of the press under the drive of the feeder. The forming blocks are arranged on the upper clamping plate 4 and move downward under the drive of the slider of the press to stamp and form the material 12 on the table surface of the press. A plurality of forming blocks for each stage of stamping and forming the left wall of the magazine are arranged along the moving direction of the material 12, such as Figure 2As shown in the figure, it includes a positioning and forming block 14 for positioning the end of the material 12, a first forming block 15 for stamping and forming the inner wall of the edge and the bottom of the left wall of the magazine respectively, a second forming block for stamping and forming the two ends of the edge of the left wall of the magazine respectively, a concave surface forming block for stamping and forming the concave surface in the middle of the left wall of the magazine, an extrusion forming block for stamping and forming the peripheral end of the left wall of the magazine, a third forming block for stamping and forming the outer wall of the edge of the left wall of the magazine, and a cutting forming block for cutting the formed left wall of the magazine and the end of the material 12.

[0026] Symmetrically arranged along the flowing direction of the material 12, there is a guide plate 13 in front of the positioning and forming block 14. The guide plate 13 is provided with guide wheels for guiding the flow of the material 12, so as to correct the position of the material 12.

[0027] In this embodiment, the material 12 moves along the table surface of the press driven by the feeder, and successively passes through each forming block for stamping and forming in each step, as Figure 3 shown, the plate-shaped material 12 moves along the table surface of the press driven by the feeder. After being corrected by the guide wheels on both sides, it first passes through the positioning and forming block 14 to stamp its end, and the end of the plate-shaped material 12 forms the shape of a positioning hole, which is convenient for the positioning of subsequent stamping steps. At the same time, the first forming block 15 is also used to stamp and form the inner wall of the edge and the bottom of the left wall of the magazine. The first forming block 15 consists of two parts, and the shape of the first forming block 15 is adapted to the shape of the gap after stamping the end of the material 12 as shown in Figure 3 the figure. Then the material 12 moves to the lower part of the second forming block, and the second forming block stamps and forms the two ends of the edge of the left wall of the magazine. The second forming block consists of two parts, and the shape of the second forming block is adapted to the shape of the gap after stamping the end of the material 12 as shown in Figure 3 the figure. Then the material 12 moves to the concave surface forming block, and the concave surface forming block stamps and forms the concave surface in the middle of the left wall of the magazine. Then the material 12 moves to the extrusion forming block, and the extrusion forming block stamps and forms the peripheral end of the left wall of the magazine. Then the material 12 moves to the third forming block, and the third forming block stamps and forms the outer wall of the edge of the left wall of the magazine to form an individual left wall of the magazine. Then the individual left wall of the magazine passes through the cutting forming block to cut between the end of the individual left wall of the magazine and the raw material plate, and the finished product of the left wall of the magazine can be obtained.

[0028] In this process, the slider of the press drives each forming block to perform a 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 two adjacent left walls of the magazine. Thus, multiple stamping processes at different stations can be completed simultaneously by a set of molds, reducing the quality risks generated in multiple processes, improving production efficiency, and saving costs.

[0029] The above are only the preferred embodiments of the present utility model and do not impose any formal restrictions on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to equivalent embodiments with equivalent changes within the scope of the technical solution of the present utility model by using the technical content disclosed above. However, as long as it does not depart from the content of the technical solution of the present utility model, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
