Problems solved by technology

[0003]The existing stamping technology requires the blank to meet the circular shape, and then it is processed by turning after stamping. The production process is complicated and the efficiency is low; at the same time, the unloading needs to be done manually, and the personnel cannot be guaranteed. Safety

Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the embodiments disclosed in the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0042] Such as figure 1 and figure 2 , in this embodiment, the solid rocket motor nozzle cap blanking die, including: an upper die 1 and a lower die 2. Wherein, the upper mold is installed on the slider of the stamping machine tool to realize the forming of the inner surface of the plug; the lower mold is installed on the working table of the stamping machine tool to realize the forming and unloading of the outer surface of the plug.

[0043] In this example, if image 3 , the upper mold 1 may specifically include: upper mold base 3, backing plate 4, guide bushing 5, punch fixing plate 6, upper cutting plate 7, fixing bolt 8, positioning pin 9, spring 10, punch top shaft 11. Upper discharge block 12 and punch 13. The specific conn...

Abstract

The invention discloses a solid rocket engine jet pipe blanking cap blanking die. The blanking die comprises an upper die and a lower die; the upper die is installed on a sliding block of a punching machine tool and used for achieving forming of the inner surface of a blanking cap. and the lower die is installed on a working table of the punching machine tool and used for achieving forming of the outer surface of the blanking cap and discharging. By means of the solid rocket engine jet pipe blanking cap blanking die, the machining efficiency of the solid rocket engine jet pipe blanking cap is improved, and the consistency of products is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of stamping dies, and in particular relates to a solid rocket motor nozzle plugging blanking die. Background technique [0002] The engine nozzle plug is one of the key components of the solid rocket motor. When the solid rocket motor is stored and ready for flight, it plays the role of sealing and moisture-proof; at the moment of engine ignition, it can quickly build up the pressure of the combustion chamber, thereby shortening the ignition delay time and making the engine ignite normally. Metal material plugs are usually made of pure aluminum or pure copper, which has strong plasticity, so the use of stamping dies to process the plugs can achieve the effect of fast forming and high dimensional accuracy. [0003] The existing stamping technology requires the blank to meet the circular shape, and then lathe processing after stamping, the production process is complicated and the efficiency is low; at the sa...
