A fully automatic forming system for cold extrusion of rod parts

Abstract

The invention provides a fully-automatic molding system for cold extrusion of rod parts, relates to the technical field of cold extrusion machining of rod parts and aims to solve the problem that machining efficiency of rod parts in the prior art is low. The fully-automatic molding system for cold extrusion of the rod parts comprises a press machine and further comprises a feeding mechanism and areceiving mechanism. Both the feeding mechanism and the receiving mechanism comprise fixture assemblies which can stretch between a base and a pressure head. Each fixture assembly comprises a clampingplate. Clamping rings are arranged on each clamping plate. Clamping holes communicating into the interior of the each clamping ring are formed respectively in the circumferential walls on two opposite sides of each clamping ring. Clamping bars are connected to the clamping holes in a threaded and penetrating manner. A feeding frame is arranged on one side of the pressure machine. A fixture assembly is connected to the feeding frame along the vertical direction in a slippage manner, while jacking rods which can be connected into openings at the bottom ends of compression molds in an inserted manner are arranged in the base along the vertical direction in a slippage manner. According to the fully-automatic molding system for cold extrusion of the rod parts, through linkage cooperation of the fixture assembly of the feeding mechanism, the jacking rods arranged at the bottoms of the compression molds in a slippage manner and the fixture assembly of the receiving mechanism, automated machining of the rod parts is achieved, and machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of cold press processing of rod parts, in particular to a fully automatic forming system for cold extrusion of rod parts. Background technique [0002] The cold extrusion process is a processing method in which the metal blank is placed in the cold extrusion die cavity, and at room temperature, the punch fixed on the press is applied to the blank to cause plastic deformation of the metal blank to produce parts; In the prior art, when the rod parts are processed into gear shafts on the gear hobbing machine, not only the production efficiency is low, but also the precision of the produced parts is poor. Therefore, the cold extrusion method is used instead of the gear hobbing machine for processing. [0003] At present, the Chinese invention patent with the publication number CN102825088A discloses a gear shaft cold extrusion die and its extrusion process. The cold extrusion die includes a gear die, and a lower...

Problems solved by technology

[0004] When using the previous gear shaft cold extrusion die and extrusion process, the staff needs to manually place the rod parts into the gear mold. After the extrusion is completed, manually drive the processed gear shaft and store it in the In the receiving box, the continuous production of rod parts can be realized. However, this processing method is greatly affected by the proficiency of the staff, and the average production efficiency is low.
