Description

Technical Field

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

[0002] A magazine is one of the essential structural components in a firearm. Generally, a magazine is composed 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] After the magazine is stamped and formed, a notch punching process is also required for the magazine housing to form the structure shape of the bullet holding mouth. The traditional notch punching die used for processing the magazine housing has a phenomenon that the two sides of the notch are inconsistent after stamping production, resulting in the appearance of the product after notch punching not meeting the usage requirements, the quality of the processed product not meeting the standard, causing waste of raw materials, and increasing the production and processing costs. Therefore, in view of this, the inventor provides a magazine notch punching die to solve the above problems. Utility Model Content

[0004] The purpose of the present utility model is to solve the problem that when punching a notch in a traditional magazine, it is easy to have a phenomenon that the two sides of the notch are inconsistent, resulting in the quality of the processed product not meeting the standard, causing waste of raw materials and increasing the production and processing costs.

[0005] To achieve the above object, the basic solution of the present utility model provides a magazine notch punching die, including:

[0006] An upper die assembly and a lower die assembly, respectively arranged on the slider and the table of a press;

[0007] A punch, arranged on the upper die assembly and driven by the upper die assembly to move vertically in a reciprocating manner;

[0008] A cutting edge, arranged on the lower die assembly;

[0009] The dimension of the punch from the width position of the bullet holding mouth is the lower limit dimension of the width of the bullet holding mouth of the magazine.

[0010] Further, the upper die assembly includes an upper die base, an upper backing plate, and an upper clamping plate; the lower die assembly includes a lower template, a lower clamping plate, a lower backing plate, and a lower die base.

[0011] Further, the punch is connected to the upper clamping plate, and the cutting edge is connected to the lower template.

[0012] Further, the upper die assembly further includes an upper pressure plate for driving the punch to move vertically, and a punch seat for installing the punch is arranged on the upper pressure plate.

[0013] Further, a cavity for vertically sliding the punch and the punch holder is provided on the lower template and the lower clamping plate.

[0014] Further, it further includes a plurality of pilot pins connected to the upper die assembly, and the bottom of the pilot pin extends out of the upper die assembly and is connected to the positioning hole on the side wall of the magazine.

[0015] Further, the pilot pin passes through the upper clamping plate and is connected to the upper backing plate.

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

[0017] Compared with the prior art, in this utility model, the magazine is positioned by inserting the pilot pin into the positioning hole on the side wall of the magazine. The upper pressure plate drives the punch holder and the punch to move downward as a whole. A notch is punched on the surface of the magazine through the gap between the punch and the cutting edge. The dimension of the distance between the punch and the width position of the cartridge holding port is the lower limit dimension of the width of the cartridge holding port of the magazine, which can effectively solve the problem of inconsistent two sides of the magazine notch, improve the product quality, thereby reducing the waste of raw materials and the production cost.

[0021] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features, and their effects according to the present utility model as follows.

[0022] The reference numerals in the accompanying drawings of the specification include: upper die base 1, upper backing plate 2, upper clamping plate 3, lower template 4, lower clamping plate 5, lower backing plate 6, lower die base 7, upper pressure plate 8, punch 9, punch holder 10, pilot pin 11, cutting edge 12.

[0023] A magazine notch punching die, the embodiment is as Figure 1As shown in the figure, it includes an upper die assembly, a lower die assembly, a punch 9 and a cutting edge 12. The upper die assembly and the lower die assembly are respectively arranged on the slider and the table of a 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. The upper die base 1, the upper backing plate 2, and the upper clamping plate 3 are detachably connected to each other by a plurality of bolts. The lower die assembly includes a lower template 4, a lower clamping plate 5, a lower backing plate 6, and a lower die base 7 which are arranged in sequence from top to bottom below the upper die assembly. The lower template 4, the lower clamping plate 5, the lower backing plate 6, and the lower die base 7 are detachably connected to each other by a plurality of bolts.

[0024] An upper pressure plate 8 is arranged on the upper clamping plate 3. A punch seat 10 is arranged on the upper pressure plate 8. A punch 9 is arranged on the punch seat 10. The cutting edge 12 is arranged on the lower template 4 of the lower die assembly. And the dimension of the position of the punch 9 from the width of the cartridge holding mouth is the lower limit dimension of the width of the cartridge holding mouth of the magazine. A cavity for the vertical sliding of the punch 9 and the punch seat 10 is arranged on the lower template 4 and the lower clamping plate 5. A plurality of pilot pins 11 are arranged on the connection of the upper backing plate 2. The pilot pins 11 pass through the upper backing plate 2 and the upper clamping plate 3 and are connected to the positioning holes on the side wall of the magazine.

[0025] During the implementation of this embodiment, the magazine that needs to have a notch punched is placed on the lower template 4 and is adapted to the die positioning surface on the lower template 4. During the downward movement of the upper die base 1, the bottom of the pilot pin 11 extends into the originally opened positioning hole on the side wall of the magazine to position the magazine. Then the upper pressure plate 8 drives the punch seat 10 and the punch 9 to move downward as a whole. A notch is punched on the surface of the magazine through the gap between the punch 9 and the cutting edge 12. And the dimension of the position of the punch 9 from the width of the cartridge holding mouth is the lower limit dimension of the width of the cartridge holding mouth of the magazine, which can effectively solve the problem of inconsistent sides of the magazine notch, improve the product quality, thereby reducing the waste of raw materials and the production cost.
