Technical Field

[0001] This application relates to the technical field of molds, and specifically discloses a continuous die for punching the right arm of a magazine. Background Art

[0002] A magazine is a feeding device. It is installed in a certain direction of the gun axis. During use, the internal support spring and the cartridge carrier plate work together to push the cartridges in it out one by one to feed the weapon. The magazine is formed by stamping a steel plate, with a smooth surface. It consists of a magazine body, a cartridge carrier plate, a support spring, a magazine bottom plate, and a support spring bottom plate. Among them, the magazine body is composed of a left arm and a right arm to form a semi-surrounding cavity for accommodating the magazine to store the magazine.

[0003] When the existing right arm of the magazine is produced and processed, multiple sets of single-process dies need to be used in sequence to obtain the product. Specifically, a feeding machine is used to sequentially feed the strip of the production raw material of the right arm of the magazine into each process die one by one, and then the slide block of the existing press drives each group of single-process dies installed on the tabletop of the fixed table to stamp the strip to obtain the finished product of the right arm of the magazine. The production efficiency is low and the labor cost is high. Therefore, in view of this, the inventor provides a continuous die for punching the right arm of the magazine to solve the above problems.

As Figure 1 shown, a continuous shaping die 12 for stamping the strip is provided on one side of the upper clamping plate 3 close to the lower template 6. A stripping assembly for separating the finished product obtained by stamping from the continuous shaping die cavity 8 is provided between the bottom of the upper clamping plate 3 and the lower template 6. Among them, the existing feeder is driven by an intermittent drive mechanism to perform the feeding and stamping process of the strip.

[0021] Among them, as Figure 1 shown, the installation frame 5 includes a lower support plate 14 provided below the lower die base 2 and detachably installed and connected to the tabletop of the fixed table, and seven groups of lower foot pads 15 provided between the bottom of the lower die base 2 and the lower support plate 14.

[0022] Among them, as Figure 1 shown, connecting and positioning pins 16 are detachably installed between the two ends of the lower foot pad 15 and the lower die base 2 and the lower support plate 14 respectively.

And so on. After the strip undergoes multiple stamping processes in the continuous shaping die cavity 8, the finished product of the magazine right arm is obtained. Subsequently, the finished product of the magazine right arm is pushed to the right end of the continuous shaping die cavity 8 and is in a suspended state on the blanking port 19 at the right end of the continuous shaping die cavity 8. At this time, the press electrically controls the lifting and pushing rod 18 to perform lifting and lowering movements, and the lifting and pushing rod 18 pushes downward the finished product of the magazine right arm in the blanking port 19 to fall into the blanking port 19 and land below the lower die holder 2, completing the blanking of the magazine right arm, thus completing the production of the magazine right arm. Multiple processes are continuously processed and produced, and the coherence of the processes enables one-step production.

[0027] Compared with the prior art, by setting the continuous shaping die cavity 8, the present utility model facilitates the continuous stamping and processing of the strip. Only one set of continuous dies is required to realize the multi-process production of the magazine right arm, simplifying the production operation and production scale of the magazine right arm, thereby reducing the production cost. At the same time, the feeder is used to push the strip of the production raw material of the magazine right arm between the upper die holder 1 and the lower die holder 2, facilitating the continuous production of the magazine right arm, greatly improving the production efficiency, and solving the problems that multiple sets of single-process dies are required to produce products during the traditional production and processing of the magazine right arm, with low production efficiency and high labor costs.

[0028] Compared with the prior art, by setting the continuous shaping die cavity 8 and using the press to drive the continuous shaping die 12 and using the feeder to push and stamp the strip in the continuous shaping die cavity 8, the strip realizes continuous stamping and shaping processing for each process in the continuous shaping cavity until the strip is stamped by the upper clamping plate 3 and the lower template 6 to be the same as the outer shape structure of the last process in the continuous shaping die cavity 8, making the production process of the magazine right arm more coherent.

[0029] Compared with the prior art, by setting the stripping assembly, the present utility model facilitates the demolding and blanking operation of the magazine right arm product obtained after stamping processing.
