Die supporting block mistake proofing device for press machine and press machine

Abstract

The invention discloses a die supporting block mistake proofing device for a press machine and the press machine. The die supporting block mistake proofing device comprises storage supports which are provided with storage parts used for storing supporting blocks. Position sensors are used for detecting whether the supporting blocks are stored in the storage parts or not and outputting electric signals. Normally-open electronic switches are connected to a power circuit of the press machine in series, and the normally-open electronic switches receive the electric signals output by the position sensors. According to the die supporting block mistake proofing device, when the position sensors detect that the supporting blocks are stored in the storage parts of the storage supports, control signals are sent to the normally-open electronic switches so as to turn off the switches, the normally-open electronic switches are located on the power circuit of the press machine and can work normally only being communicated with the press machine, and therefore the circumstance that the press machine mistakenly collides with the supporting blocks is avoided, and potential safety hazards of the supporting blocks are eliminated.

Description

technical field [0001] The invention relates to mechanical processing equipment, in particular to a mold support block error prevention device for a press and a press. Background technique [0002] Presses are widely used in processes such as cutting, punching, blanking, bending, riveting and forming. Generally, presses include a fixed lower part and an upper part that can reciprocate up and down. During the manufacturing, transportation and During the maintenance process, in order to protect the profile of the press, usually a number of support blocks are placed between the upper and lower parts of the press production mold. [0003] When the press is working, it is necessary to remove the support block in the mold to prevent it from blocking the up and down reciprocating movement of the upper part of the mold. During on-site construction, if the operator forgets to remove the support block, it will cause a violent collision between the upper mold of the press and the supp...
