Hot sizing device and hot sizing method for thin-wall stamping part

Abstract

The invention discloses a hot sizing device and hot sizing method for a thin-wall stamping part, and aims at solving the problems of warping and deformation of the thin-wall stamping part which is subjected to hot sizing to improve the production efficiency and reduce the production cost. The adopted technical scheme is as follows: the hot sizing device comprises a bottom plate (1) and positioning pins (5), wherein the positioning pins (5) are fixedly arranged at two ends of the bottom plate (1); the bottom plate (1) is provided with a plurality of loading boxes (2), a plurality of thin-wall stamping parts (3) can be placed in the loading boxes (2) in a stacked way, cavities inside the loading boxes (2) are matched with the thin-wall stamping parts (3) in size structure, and the stacked height of the plurality of thin-wall stamping parts (3) is aligned to the upper planes of the loading boxes (2); and the upper ends of the loading boxes (2) are provided with press plates (4), and the press plates (4) are sleeved on the positioning pins (5) so as to press the thin-wall stamping parts (3) in holes of the loading boxes (2).

Description

technical field [0001] The invention belongs to the technical field of thermal correction, and in particular relates to a thermal correction device and a thermal correction method for thin-wall stamping parts. Background technique [0002] At present, the heat correction of thin-walled stamping parts is superimposed by multiple thin-wall stamping parts, and the thin-wall stamping parts are placed on the bottom plate by manual operation. solid purpose. Because there is a huge stamping stress in the thin-walled stamping parts after stamping, it is necessary to eliminate the stamping stress, that is, heat correction treatment, and during the heat correction process, the internal stress release of the thin-wall stamping parts is irregular, coupled with the existing The tooling cannot compress the thin-walled stamping parts, so after thermal adjustment, the thin-walled stamping parts will be warped and deformed, which must be reworked, and the parts will be scrapped directly in ...
