Horizontal dual-mold cold extrusion mechanism and forming production process

Abstract

The invention discloses a horizontal dual-mold cold extrusion mechanism and a forming production process. The horizontal dual-mold cold extrusion mechanism comprises a multi-connecting-rod toggle rodtype mechanical driving mechanism, an automatic feed mechanism and a body, wherein the multi-connecting-rod toggle rod type mechanical driving mechanism comprises a sliding block; the front end of thesliding block is connected with two punching head bases; the front ends of the two punching head bases are connected with two convex molds respectively; the body is provided with two transversely parallel dip mold holes; the two dip mold holes are internally provided with two concave mold cushion blocks respectively; the front ends of the two concave mold cushion blocks are provided with two concave molds respectively; the two concave molds are both internally provided with concave-mold mold cavities; the multi-connecting-rod toggle rod type mechanical driving mechanism is connected with theautomatic feed mechanism through a gear and a lever shaft; the lever shaft is located on an oscillating rod; the oscillating rod is connected with two manipulators respectively. Horizontal dual moldsare subjected to cold extrusion at the same time and outputs products at the same time; the continuous and high-efficiency production is realized; the convex molds and the concave molds are both provided with adjustment and fixation devices; products subjected to cold extrusion forming are uniform and stable in size, thick at bottoms, small in wall thickness tolerance high and precision; the mechanical performance of the products subjected to the cold extrusion forming is improved and the percent of pass is high.

Description

technical field [0001] The invention relates to the field of metal processing, in particular to a horizontal double-mode cold extrusion mechanism and a forming production process. Background technique [0002] At present, for the processing of non-ferrous metal workpieces such as cylinders and cans, hydraulic presses or ordinary punches or ordinary horizontal extruders are used. The production speed is relatively slow, and 16-100 pieces are produced per minute. The production efficiency is low and the production cost is high. High, cylindrical and can-shaped metal products produced by hydraulic presses or ordinary punching machines, the dimensional accuracy of the bottom is unstable. The production industry of non-ferrous metal cylindrical and can-shaped products needs to provide an extrusion forming equipment and production forming process with high production efficiency and high product precision. Contents of the invention [0003] In order to solve the above problems, ...
