Plate positioning device with limiting block

Abstract

The invention relates to a plate positioning device with a limiting block. The plate positioning device comprises an installation plate, a positioning plate, a detection device, the limiting block, asensor, a rotating shaft, a detection piece, a connection piece and a positioning supporting plate. When a plate is fed into a die cavity, the middle portion of the plate makes contact with the highest point of a male die, the free end of the plate is suspended, a gap exists between the free end of the plate and the positioning plate, the free end of the plate shakes up and down due to the effectof gravity and touches the limiting block, and the limiting block bears force and rotates around the rotating shaft; and after the plate enters the detection area of the sensor, the limiting block resets duet to the effect of gravity to limit vertical shaking of the plate, the free end of the plate is limited in the detection area by the limiting block and is made to touch the detection device togenerate movement, the detection piece is driven by the movement to get close to the sensor, and the sensor transmits a continuous signal to a stamping device to conduct forming on the plate after detecting the continuous signal. By means of the plate positioning device with the limiting block, continuity of the detection signal can be ensured, die production stoppage can be reduced, stability ofstamping die automated production can be achieved, and the stamping automated production efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of stamping die manufacturing, and in particular relates to a plate positioning device with a limiting block. Background technique [0002] With the rapid development of China's automobile industry, the degree of automation of stamping die production has also been rapidly developed. It is further required to add some intelligent devices in the design and manufacture of automobile dies to adapt to the current rapid development of automatic production of stamping dies. [0003] During the die stamping production process, the plate shakes up and down to cause unstable positioning, which will directly affect the continuity of automated production, and will affect the quality of stamping parts and even cause waste products. [0004] When the stamping die is produced, when the plate is fed into the mold cavity, the middle part of the plate is in contact with the highest point of the punch, the free end of the plat...

AI Technical Summary

Problems solved by technology

The free end of the plate shakes up and down, causing the detection signal to be intermittent, and the automatic press cannot receive continuous detection signals, which cannot realize automatic in-line production, and the efficiency of automatic production is low
