Abstract

The invention relates to a large sheet metal stretch formed piece correcting device which comprises a base with a linear chute formed in the upper surface, a cycloid gear reducer installed on the base, a transmission shaft, a first bearing supporting device, a first sliding seat rolling device, a second sliding seat rolling device and a second bearing supporting device; and the first bearing supporting device, the first sliding seat rolling device, the second sliding seat rolling device and the second bearing supporting device are sequentially installed on the base along the transmission shaft. For the large sheet metal stretch formed piece correcting device, a springback edge is corrected and sized by transferring pressure with machinery, the number of ejector rods can be changed according to the size of a workpiece by adopting an electric device, a moving distance of a sliding seat frame is set according to a springback amount of the workpiece, a correction frequency is quickly and flexibly controlled with a speed reducer, the workpiece is extruded to perform a proper quantity of deformation through intermittent pushing, the deformation is gradually converted to plastic deformation at a certain pushing frequency, deformation springback is eliminated, a size reference is returned, and the correction effect is achieved.

Description

technical field [0001] The invention relates to the field of sheet metal stretching, in particular to a correction device for large-scale sheet metal stretching formed parts for correcting the shape and size of workpieces after sheet metal forming and stretching. Background technique [0002] In the stretch forming process of sheet metal structural parts, the metal sheet is stretched into various shell shapes in the mold by a hydraulic press. After being stretched by a hydraulic machine, the workpiece product will have a shape rebound phenomenon when it is released from the mold, resulting in shape and size errors of the stretched part. Therefore, after stretching, it is often stretched by methods such as re-pressing, pressure-holding or manual force shaping. Stretch correction work. This calibration work is time-consuming, difficult to control, and difficult to guarantee accuracy. Contents of the invention [0003] In order to solve the deficiencies in correcting the sp...
