Used for punching and concave dies of channel steel beam punching equipment supporting error prevention mechanism

Abstract

The invention proposes an anti-error mechanism for the convex and concave dies of the grooved steel beam punching equipment. The sliding positioning seat of the die is fixed on the punching pliers of the CNC punching grooved steel beam hole equipment, and the integrated blocks of the multi-standard die are guided and supported on the On the sliding positioning seat of the concave mold, the multi-specification concave mold integrated block realizes reciprocating movement through the hand wheel and the rack and pinion auxiliary drive. The multi-specification concave mold integrated block is installed with a variety of different specifications of the concave mold, and one end of the multi-standard concave mold integrated block The connecting block and the connecting pin are connected with a pull wire displacement sensor, and the pull wire displacement sensor is connected with the electrical control system. Through the pull wire displacement sensor, the output of the analog signal of the die position of different specifications is realized, and the electrical control system transmits the monitoring signal to the touch screen of the operating table. The invention uses a wire displacement sensor to realize on-line real-time monitoring of the positions of dies of different specifications, improves the punching productivity, and avoids the phenomenon of forgetting matching displacement of multi-standard die integrated blocks during hole processing and production, and causing errors.

Description

technical field [0001] The invention relates to an error-preventing mechanism for matching convex and concave dies of channel-shaped steel beam punching equipment. Background technique [0002] At present, in the CNC groove punching steel beam hole equipment, the machine base is supported by a dual-coordinate moving guide rail sub-assembly, the punching pliers are supported on the dual-coordinate moving guide rail sub-assembly, and the lower end of the punching pliers is equipped with multi-specification dies for integration. The punch is fixed on the guide pin / punch exchange mechanism at the upper end of the punch body, and the punch and punch are realized through the guide pin and the guide pin / punch exchange mechanism by using the existing holes in the outer beam of the double-layer steel beam part. The coincidence of the existing hole centers of the stringer. In order to realize the replacement of different punching dies, the production method of replacing the punches f...

Problems solved by technology

In production, since the multi-specification die integrated block is located on the inner surface of the channel steel beam, the position is relatively hidden, and it is very easy for the die integrated block to forget to match the displacement and cause an error, resulting in serious production accidents; when there are many die specifications, Unable to realize on-line monitoring and mold position memory functions, resulting in defects such as low production efficiency
