Abstract

The invention discloses a primary molding tool of omega-shaped elastic strips in automatic production. The primary molding tool comprises an upper template and a lower template; an upper mold base and a material return base are arranged on the upper template; an upper mold roller is arranged on the upper mold base; a material return guide sleeve is arranged in the material return base; a pressure spring is arranged in the material return guide sleeve; a material return block is connected to the material return guide sleeve through an internal hexagonal bolt; a short lower mold and a middle bearing lower mold are arranged on the lower template; and a lower mold roller and a lower mold cushion block are arranged on the short lower mold. Compared with the prior art, the primary molding tool has the following beneficial effects: a material return mechanism is added on the molding tool, so that compressed workpieces are stably fixed on a lower mold, and workpiece stabilization positions are guaranteed. The lower mold cushion block is inlaid with R groove hard alloy, so that the service life is prolonged, and meanwhile, the workpiece cannot have indentations when the radius R of the molded workpiece is guaranteed.

Description

technical field [0001] The invention relates to a preliminary forming tool for automatic production of ω-shaped spring bars. Background technique [0002] The ω-shaped elastic bar was originally operated manually without a material return mechanism. After a sequence of pressing, the workpiece sometimes falls on the lower mold and sometimes is taken up by the upper mold, which cannot meet the needs of automated production. The material return mechanism is added, and the workpiece is stably fixed on the lower mold after pressing, ensuring the stable position of the workpiece. The lower mold pad is inlaid with hard alloy with R groove, which improves the service life, and at the same time ensures that the workpiece will not have indentation when molding workpiece R. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a tool for automatic production of primary forming of ω-shaped spring bars...
