Problems solved by technology

Cold heading is a continuous automatic processing method with a production efficiency of 3,000 pieces per hour. Stamping is a manual single-shot processing method with a production efficiency of about 400 pieces per hour, making stamping processing the bottleneck of the entire process chain.
The processing efficiency of the entire product is greatly reduced, and its production cost is greatly increased. In order to improve the processing efficiency of the product and have great competitiveness in the same industry, it is necessary to shorten the processing procedure, improve production efficiency, and reduce production costs.

Abstract

The invention provides a cold heading opening and closing die of an automobile double-flange special-shaped work piece. The die comprises a punch part and a die making part, and is characterized in that the punch part comprises a punch casing, a punch spring, a punch ejector sleeve, a punch head and a spring sleeve; the die making part comprises a die casing, an opening and closing die flap, an opening and closing die casing, an opening and closing die opening pin, an opening and closing die opening spring, a synchronous retaining pin, an opening and closing die ejector pin, an opening and closing die casing die flap cushion block, a die making ejector sleeve, a die making plunger, a die making plunger rear spring and a three-wire set. The die is reasonable in design, greatly improves the operating efficiency, reduces the production cost, ensures that two flanges are formed by impacting at one step, has continuous and automatic production capacity, and solves technical bottlenecks in the prior art.

Description

technical field [0001] The invention relates to the technical field of production of special-shaped double-flange parts of automobiles, in particular to a cold heading opening and closing mold for special-shaped double-flange parts of automobiles. Background technique [0002] At present, the processing of double-flange special-shaped parts of automobiles usually adopts the form of cold heading processing one end flange and stamping processing the other end flange. The forming of the product requires two processing procedures. Cold heading is a continuous automatic processing method with a production efficiency of 3,000 pieces per hour. Stamping is a manual single punch processing method with a production efficiency of about 400 pieces per hour, making stamping processing the bottleneck of the entire process chain. The processing efficiency of the entire product is greatly reduced, and its production cost is greatly increased. In order to improve the processing efficiency of...
