Multifunctional numerically-controlled rear material stopping device

Abstract

The invention discloses a multifunctional numerically-controlled rear material stopping device which comprises an X-axis rear material stopping device body, an R-axis rear material stopping device body and a Y-axis rear material stopping device body. The X-axis rear material stopping device body comprises a supporting base, a linear guide rail pair, an X-axis ball screw and a servo motor arranged on the X-axis ball screw. The R-axis rear material stopping device body comprises a sliding guide rail fixed to the supporting base, an R-axis bearing seat arranged on the sliding guide rail, two R-axis gear shafts arranged on the R-axis bearing seat and located on the same straight line, and a servo motor arranged between the two R-axis gear shafts. The Y-axis rear material stopping device body comprises a crossbeam lifting stand column fixed to the R-axis bearing seat, a rack arranged on the crossbeam lifting stand column, and a speed reduction mechanism arranged in the crossbeam lifting stand column. The multifunctional numerically-controlled material stopping device has the advantages of being high in precision and speed, low in noise, attractive in appearance, convenient to install, easy to operate, high in safety and the like.

Description

technical field [0001] The invention belongs to the field of sheet metal bending, and in particular relates to a numerically controlled multifunctional rear stopper, which is used for precision control of the stopper of a sheet metal bending machine in the forging industry. Background technique [0002] The traditional backgauge is split and installed on both sides of the machine tool, and the motor drives the chain to drive. When installing, the ball wires on both sides and the parallelism of the rod linear guide rail up and down, left and right cannot be guaranteed, so the speed cannot be too fast, and the noise will be too fast. If the chain is used for a long time, it will stretch or break, causing the two sides to be out of sync, and the positioning accuracy and normal use of the stopper cannot be guaranteed. [0003] The traditional back gauge beam cannot be raised and lowered, and the shelf cannot be lowered on the lower mold of the bending machine, so there is a gap ...
