Male die and female die matching error prevention mechanism used for trough-type steel beam punching equipment

Abstract

The invention provides a male die and female die matching error prevention mechanism used for trough-type steel beam punching equipment. A female die sliding positioning base is fixed to a punching forcep body of the numerical control trough-type steel beam punching equipment; an integrated block of multiple specifications of female dies is supported on the female die sliding positioning base in an oriented mode, achieves reciprocating movement through driving of a hand wheel and a gear and rack pair and is provided with the multiple female dies of different specifications; one end of the integrated block of the multiple specifications of female dies is connected with a stay wire and displacement sensor through a connection block and a connection pin; the stay wire and displacement sensor is connected with an electrical control system; output of position analog signals of the different specifications of female dies is achieved through the stay wire and displacement sensor, and the electrical control system transmits monitoring signals to a control console touch screen. Online and real-time monitoring of the positions of the different specifications of female dies is achieved through the stay wire and displacement sensor, the punching productivity is improved, and the phenomenon that as matched displacement of the integrated block of the multiple specifications of female dies is forgotten during hole machining and production, an error is caused is avoided.

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
