A compound mold for bottom pressing, bottom cutting and typing of stamping outer ring

Abstract

The invention relates to a compound mold for pressing and cutting the bottom and typewriting in punching an outer ring. The compound mold comprises an upper mold and a lower mold, wherein the upper mold comprises a top rod which is arranged in a mold handle; the mold handle is also internally provided with a cushion plate; a bottom-pressing guide sleeve is arranged under the cushion plate and is internally provided with a bottom-cutting concave mold; the bottom-cutting concave mold has the functions of pressing the bottom, typewriting, cutting the bottom and discharging, and is internally provided with a ramming rod; the ramming rod is arranged at the bottom end of the top rod; the lower mold comprises a lower mold seat which is internally provided with a bottom-pressing convex mold; and the bottom-pressing convex mold is provided with a bottom-cutting punching head. The compound mold has the advantages that after the structure is adopted, the strength of the bottom-cutting concave mold is improved, the damage does not easily occur, and the loss of the mold is reduced; simultaneously the bottom-cutting concave mold has the functions of pressing the bottom, typewriting, cutting the bottom and discharging so as to realize the scheme of the procedure combination; due to the procedure combination, the labor productivity is improved, and the production cost is reduced; alloy is embedded in the bottom-cutting guide sleeve, so that the roundness of the outer diameter of a product and the durability of the mold are ensured; and due to the protection of the bottom-pressing guide sleeve, the deformation of the product is controlled and the quality of the product is improved.

Description

technical field [0001] The invention relates to the field of processing and design of stamping bearings, in particular to a composite mold for stamping outer ring bottom pressing, bottom cutting and typing. Background technique [0002] At present, bottom pressing, bottom cutting, and typing are generally divided into 2-3 processes in stamping outer ring processing. There are many processes and low production efficiency, and because there is no outer diameter control for typing, the roundness of the outer diameter of the product is out of tolerance. , affects product quality, is not conducive to the promotion of product quality, and at the same time, due to the thin thickness of the working part of the bottom-cut die, it is easy to be damaged, which restricts production. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a composite mold for stamping the outer ring bottom, bottom cutting, and typing, which ca...
