Molding mechanism for spline sleeve cold extrusion die

Abstract

The invention provides a molding mechanism for a spline sleeve cold extrusion die. The molding mechanism comprises slanted sliding blocks. The end, close to a positioning seat, of each slanted slidingblock is provided with a square groove. The end, close to the positioning seat, of each slanted sliding block is provided with a molding plate connected detachably. The molding plates are located onthe corresponding square grooves. The side, far from each slanted sliding block, of each molding plate is provided with two symmetric square molding blocks. The end of each square molding block is provided with a round protrusion. The end, far from the positioning seat, of each slanted sliding block is an inclined bevel. Extended stop dogs are arranged on the upper portion, corresponding to the slanted sliding blocks, of a die socket. The bottom of the die socket is provided with male dies distributed circumferentially. The other end of each male die is provided with an inclined plane. The bottoms of the male dies are located above the inclined bevels of the slanted sliding blocks. The molding mechanism for the spline sleeve cold extrusion die, provided by the invention, can extrude a product to be machined conveniently and rapidly in the pressing process without affecting mounting and dismounting of the product. The replacement efficiency is improved, the structures of all parts are matched closely, and the molding mechanism is suitable for high-efficiency mass production.

Description

technical field [0001] The invention belongs to the field of spline sleeve forming equipment, in particular to a forming mechanism for a spline sleeve cold extrusion die. Background technique [0002] The spline sleeve is a mechanism that is used in pairs to cooperate with the spline shaft. In order to ensure the accuracy of the fit and the stability of use, it is necessary to have high requirements for the processing quality of the spline sleeve, and due to the thin wall of the spline sleeve Requirements, the commonly used processing methods have low precision, and it is easy to cause product deformation during the clamping process, and the cost is high, which is not conducive to production and processing. In view of this situation, the present invention proposes a forming mechanism for a spline sleeve cold extrusion die. Through the design of this forming mechanism, the product to be processed can be extruded conveniently and quickly when pressing down. The mold is automa...
