Abstract

The invention provides a multistation cold extrusion forming method for a strong wedge anchor, which comprises the following steps: cutting for forming a material part for cold extrusion, wherein the diameter of a cut material is equal to that of a rolled tooth section of the wedge anchor; and cold extrusion processing performed after cutting, wherein one or a plurality of times of cold extrusion is performed to reduce and elongate the upper part of the material part and make the head part of the material part into a shape of a lead angle, one or a plurality of times of cold extrusion is performed to reduce the tail part of the material part into a shape of a knocking head of the wedge anchor through cold extrusion, and the head part of the material subjected to cold extrusion processing is made into a reverse cone head of the wedge anchor. The method can manufacture the wedge anchor which used to be machined by cold extrusion through reasonable drawing of station and working procedures, is high in speed, precision and production efficiency, and avoids problems of expansion failure due to traces and the like of the prior machining, greatly saves raw material and reduces production cost. In addition, cold extrusion improves the mechanical performance of products and provides the products with more advantages in use function.

Description

technical field [0001] The invention relates to the technical field of manufacturing a powerful car repair gecko for construction. Background technique [0002] The powerful car repair gecko is a fastener used in high-end buildings. Its shape from the beginning to the end is an inverted cone head, the neck of the expansion tube, the limit step of the expansion tube, the thread rolling section, and the knocking head. . In its powerful car repair gecko, the diameter of the limit step is the largest, and the diameter difference between it and the neck is relatively large. Existing powerful car repair geckos for construction are all processed by turning, which not only has many procedures, but also is difficult to process and low in efficiency. . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-position cold extrusion forming method of a powerful car repair gecko, which can save raw materials, reduce produc...
