A lift-opening-mold-closing transmission structure for cold heading equipment

Abstract

The invention discloses a lifting mold opening and closing conveying structure of cold heading equipment, and relates to the technical field of the cold heading equipment. The structure comprises a stripping device, wherein the top of the stripping device is fixedly connected with a lower mold, the two sides of the top of the lower mold are both fixedly connected with lower mold positioning columns, the middle of the side, far away from the stripping device, of the lower mold is fixedly connected with a mold lifting device, the back surface of the mold lifting device is fixedly connected witha lifting balance device, the outer surfaces of the ends, far away from the lower mold, of the lower mold positioning columns are slidably connected with upper mold positioning sleeves, the sides, faraway from the lower mold positioning columns, of the upper mold positioning sleeves are fixedly connected with an upper mold, and a cold heading positioning block is fixedly connected to the middle of the side, close to the mold lifting device, of the upper mold. The structure can automatically realize lifting and machining surface replacement of a cold heading part mold, a processing part can bereplaced, manual operation is not needed, the personal safety is protected, the processing efficiency is improved, and the time is saved.

Description

technical field [0001] The invention relates to the technical field of cold heading equipment, in particular to a lifting, opening and closing mold transmission structure of cold heading equipment. Background technique [0002] The cold heading machine is a special equipment mainly used for mass production of fasteners such as nuts and bolts. The earliest cold heading machine in the world originated from Germany. The purpose of developing the cold heading machine at that time was mainly to manufacture bullet casings in large quantities during World War II. According to the metal plastic deformation theory, the cold heading process applies a certain pressure to the metal blank at room temperature to cause plastic deformation in the mold cavity and form it according to the specified shape and size. High-quality metal materials with good "plastic deformation" must be selected, such as riveting screw steel, whose chemical composition and mechanical properties have strict standa...

Problems solved by technology

[0004] Aiming at the deficiencies of the existing technology, the present invention provides a lifting mold opening and closing transmission structure for cold heading equipment, which solves the problem that most of the existing cold heading equipment is directly positioned and the position is defined manually, and the lifting is realized. And the replacement of products not only greatly increases the labor intensity, but also wastes a lot of time, reduces the processing efficiency, and is easy to endanger personal safety.
