Description

Technical Field

[0001] This application relates to the technical field of stamping dies, and specifically discloses a reed continuous die. Background Art

[0002] A reed is one of the essential structural components in a firearm. Usually, a reed is formed by stamping a raw material plate.

[0003] Since the reed is not a flat component, during the stamping production process of the reed, the reed usually needs to be stamped and formed multiple times, that is, multiple sets of dies and stamping equipment are required to stamp and process the reed in sequence. 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 quality of the finished reed is affected by each stamping equipment, making it difficult to control the quality of the finished product.

[0004] A progressive die refers to a cold stamping die that uses a strip of stamping raw material and 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 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 reeds. Therefore, in view of this, the inventor provides a reed continuous 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 reed production process, stamping and forming need to be carried out on multiple pieces of equipment, resulting in a relatively high equipment cost, a long processing cycle, and a low production efficiency.

[0006] To achieve the above purpose, the basic solution of the present utility model provides a reed continuous die, 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 number 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, respectively for stamping and forming in each stamping step of the reed.

[0010] Further, the forming block includes a positioning forming block for positioning the end of the material, an end face forming block for forming the reed pieces at both ends of the material, a punching forming block for punching adjacent materials, a punching forming block for punching the two ends of the punched material, a folding forming block for folding the end of the punched material, an extrusion forming block for extruding the middle of the folded material to form a V-shaped reed structure, and a cutting forming block for cutting the formed reed and the end of the material.

[0011] Further, the upper die assembly includes an upper die base, 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, and the upper die base, the upper backing plate, and the upper clamping plate are detachably connected to each other.

[0012] Further, the forming blocks are sequentially arranged on the upper clamping plate 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, 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 below the upper die assembly. The stripping back plate, the stripping plate, the lower template, the lower backing plate, and the lower die base are detachably connected to each other.

[0014] Further, the support assembly includes a lower pad foot and a lower support plate arranged in sequence from top to bottom below the lower die assembly. The top of the lower pad foot is connected to the lower die base.

[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 present 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 of adjacent two reed pieces. Then, 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 production efficiency, saving costs, and solving the problems in the traditional reed production process, such as the need for stamping and forming on multiple devices, resulting in high equipment costs, long processing cycles, and low production efficiency.

[0022] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following will, in conjunction with the drawings and preferred embodiments, detail the specific implementation manners, structures, features, and their effects of the present utility model as follows.

[0023] The reference numerals in the drawings of the specification include: upper die base 1, upper backing plate 2, upper clamping plate 3, stripping back plate 4, stripping plate 5, lower template 6, lower backing plate 7, lower die base 8, lower foot pad 9, lower support plate 10, material 11, positioning forming block 12, end face forming block 13, punching and cutting forming block 14, punching forming block 15, folding angle forming block 16, extrusion forming block 17, cutting forming block 18, and detection probe 19.

[0024] The reed continuous die, as shown in the embodiment Figure 1 is 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 die base 1, an upper backing plate 2, and an upper clamping plate 3 arranged in sequence from top to bottom. The upper die base 1 is connected to the slider of the press, and the upper die base 1, the upper backing plate 2, and the upper clamping plate 3 are detachably connected to each other through a plurality of bolts; the lower die assembly includes a stripping back plate 4, a stripping plate 5, a lower template 6, a lower backing plate 7, and a lower die base 8 arranged in sequence from top to bottom and below the upper die assembly. The stripping back plate 4, the stripping plate 5, the lower template 6, the lower backing plate 7, and the lower die base 8 are detachably connected to each other through a plurality of bolts. The support assembly includes a lower foot pad 9 and a lower support plate 10 arranged in sequence from top to bottom and below the lower die assembly.

[0025] The material 11 for continuous stamping production moves along the tabletop of the press driven by a feeder. The forming blocks are arranged on the upper clamping plate 3 and move downward driven by the slider of the press to stamp and form the material 11 on the tabletop of the press. A plurality of forming blocks for each stage of the reed stamping are arranged along the moving direction of the material 11, such as Figure 2 shown, including a positioning forming block 12 for punching and grooving the end of the material 11 in sequence, an end face forming block 13 for forming reeds at both ends of the material 11, a blanking forming block 14 for blanking adjacent materials 11, a punching forming block 15 for punching both ends of the blanked material 11, a folding forming block 16 for folding the end of the punched material 11, an extrusion forming block 17 for extruding the middle part of the folded material 11 to form a V-shaped reed structure, and a cutting forming block 18 for cutting the formed reed from the end of the material 11.

[0026] A detection probe 19 is arranged at the outermost end in the moving direction of the material 11. The two detection probes 19 respectively scan the end state of the material 11 after the reed is cut to detect whether the reed is produced normally.

[0027] In this embodiment, the material 11 moves along the tabletop of the press driven by a feeder and passes through each forming block in sequence for stamping and forming in each step, such as Figure 3 shown, the plate-shaped material 11 moves along the tabletop of the press driven by a feeder. First, it passes through the positioning forming block 12 to stamp both ends of it, and the two ends of the plate-shaped material 11 form the shape of notches and positioning holes, so as to facilitate the positioning of subsequent stamping steps. The material 11 with notches and positioning holes 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 3 shown. The end face forming block 13 stamps both ends of the material 11 to form the planar shape at both ends of the reed. Then the material 11 moves to the blanking forming block 14, and the blanking forming block 14 blanks two adjacent reeds, so that individual reed bodies are formed on the material 11 plate. The blanked material 11 moves to the punching forming block 15 to punch both ends of each reed body. After punching, it enters the lower part of the folding forming block 16, and the folding forming block 16 folds both ends of the reed body. The folded reed body enters the lower part of the extrusion forming block 17, and the extrusion forming block 17 bends downward along the reed body, so that the reed body forms a V-shaped reed structure. Then the reed body passes through the cutting forming block 18 to cut between the end of the reed body and the raw material plate, and the completed reed product can be obtained.

[0028] In this process, the slider of the press drives each forming block to perform a vertical reciprocating motion synchronously. And for each reciprocating motion of the forming block, the feeder drives the raw material plate forward once, and the moving distance is the synchronous distance between two adjacent reeds. Thus, 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, and saving costs.
