The invention belongs to the technical field of mechanical equipment, and particularly relates to an anti-rebound bending mould for boards for winch production. The anti-rebound bending mould comprises an upper mould, a lower mould, an arc-surface pressure head arranged on the bottom of the upper mould, and a U-shaped mould cavity arranged in the lower mould, wherein a board is suitable for horizontally getting across the surface of the U-shaped mould cavity; and the arc-surface pressure head is suitable for pressing the board to enter the U-shaped mould cavity to perform bending action. In abending process, the board is blocked between the arc-surface pressure head and the inner side of the U-shaped mould cavity to reduce bending rebound, so that bending precision and rebound resistanceof the board are improved.
Description
technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to an anti-rebound bending mold for a plate used in winch production. Background technique [0002] Existing winches are generally formed by welding plates of various shapes. The raw sheet material is bent and formed into various shapes for use in different parts of the winch. The existing plate bending process generally uses the side of the round steel to bend the two ends of the plate with the bending tool to make the plate bend and shape, resulting in the rebound of the plate after bending and forming, which has a large dimensional error with the design requirements , it is difficult to be used for the welded assembly of the winch. Contents of the invention [0003] The object of the present invention is to provide an anti-rebound bending die for a plate used in winch production to reduce bending and rebound. [0004] In order to solve the above-ment...
