Problems solved by technology

At the same time of development, some unavoidable problems are also encountered: for example, the mold of stamping parts cannot be maintained in time during frequent mass production, so the state of stamping parts is unstable, and welding is not guaranteed at the same time
Gas shielded welding requires operators with special skills, requires filler materials, and produces a large amount of welding fume

Abstract

An automobile seat cushion rear pipe cold forming technology belongs to the technical field of cold processing of metal parts in automobile manufacturing industries. The cold forming technology comprises the step 1, starting forming mould equipment to enable the forming mould equipment to be in a work state, the step 2, placing a product into a first mould cavity of a forming mould, and starting the mould to axially extrude the product to form an axial symmetrical groove, the step 3, placing the product in a first process into a second mould cavity of the mould, and starting the mould to axially extrude the product, the step 4, placing the product in a second process and a product in the process into a third mould cavity of the mould, starting the forming mould to integrally extrude the two products to enable the two products to be in interference fit and finishing the last process, and the step 5, closing the forming mould equipment after process finishes to enable the equipment to be in a general maintenance state. The automobile seat cushion rear pipe cold forming technology guarantees high stability and efficiency of products, removes special-skill workers, avoids filling materials, is free of welding dust, enables equipment to be easy to maintain and enables a worker to be capable of distinguishing formed products through appearance detection.

Description

technical field [0001] The invention belongs to the technical field of cold processing of metal parts in the automobile manufacturing industry, and in particular relates to a cold-bending stamping forming process for the metal skeleton of an automobile seat cushion. Background technique [0002] In 2012, the production and sales of passenger cars in my country reached more than 15 million. It is expected that the sales of passenger cars in my country will exceed 20 million in 2013. Facing such a rapidly developing market, the output of the car industry is also advancing by leaps and bounds. At the same time of development, some unavoidable problems are also encountered: for example, the mold of stamping parts cannot be maintained in time during frequent mass production, so the state of stamping parts is unstable, and welding is not guaranteed at the same time. However, for cars, which are frequently used and are closely related to everyone's life and life safety, it is neces...
