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.
