Abstract

The invention provides a control system for the pressure joint process of a detonating cord, and aims at solving the situation that in the current manufacturing link pressure joint process of initiating explosive devices, labor intensity is large, and efficiency is low. According to the scheme, the control system comprises the following steps that S1, the information of the detonating cord is scanned through a scanner, and a result is stored to a computer; S2, a metal sleeve of the detonating cord is manually mounted and is fed onto a machine claw of a four-freedom-degree feeding robot; S3, anoperation platform is started by a worker, the four-freedom-degree feeding robot tightens the machine claw, and the metal sleeve end of the detonating cord is fed into a pressure joint opening downwards through operations of ascending, rotating, leftward movement and descending successively; and S4, after ascending, a pressure joint execution mechanism executes pressure joint operation, after operation is completed, the pressure joint execution mechanism returns to the initial position, the machine claw is loosened, and the detonating cord is taken out manually. The pressure joint process ismainly divided into a detonating cord feeding and locating process and a pressure joint process, and the production efficiency and operation safety are greatly improved.

Description

[0001] The invention belongs to the field of aerospace pyrotechnics production, and relates to a detonating cord crimping process control system. Background technique

[0002] In the field of aerospace pyrotechnics production, detonating cord production has always been an indispensable and important production link. Reasonably improving the production process of detonating cord can effectively improve the product performance of detonating cord, reduce production cost and improve product reliability. There is still a long way to go before the current production process is fully automated. There are a series of problems such as low work efficiency, high production cost, and insufficient processing accuracy, which make it difficult to carry out the post-processing of some detonating cords and make the final product unusable. Contents of the invention

[0003] In view of this, the object of the present invention is to provide a detonating cord crimping process control system, im...
