Problems solved by technology
[0003] In the prior art, the end of the steel pipe is processed into an arc shape mainly by cutting with a more traditional cutting sheet, or by using more advanced wire cutting and laser cutting. The arc structure of the cutting sheet cutting process is irregular and the work efficiency is low , while the operation energy consumption of wire cutting and laser cutting is relatively high, and the purchase and maintenance costs of processing equipment are relatively high

The invention discloses an arc machining process for the tail end of a steel pipe of an automobile seat. The arc-shaped machining process comprises the following steps of 1, steel pipe fixing step, namely, one end of steel pipe raw material needing to be machined is placed in a steel pipe raw material fixing groove of a fixed lower die, a movable upper die is arranged right above the fixed lower die, and the end, needing to be machined, of the steel pipe raw material is fixed through the lower pressure of the movable upper die; and 2, steel pipe punching step, namely, the end, needing to be machined, of the steel pipe raw material is punched in the direction perpendicular to the steel pipe raw material fixing groove through a steel pipe arc-shaped punching cutter, and the fixed lower die is provided with an arc-shaped punching cutter groove for guiding the steel pipe arc-shaped punching cutter; the steel pipe arc-shaped punching cutter is of a circular pipe-shaped structure and has thesame radius as the arc-shaped radius needing to be formed at the tail end of the steel pipe raw material, and a wedge-shaped punching cutting edge is arranged at the end, facing the arc-shaped punching cutter groove, of the steel pipe arc-shaped punching cutter. The machining process has the advantages that energy consumption and equipment purchase and maintenance cost are reduced.
Description
technical field [0001] The invention relates to the technical field of production and processing technology of automobile seats, in particular to a processing technology for arc-shaped ends of steel pipes of automobile seats. Background technique [0002] The car seat is mainly composed of the seat internal support frame, the seat filling material and the seat encapsulation skin, among which most of the support components of the seat internal support frame are processed by steel pipe, because the steel pipe has high strength and relatively It has a stable structure and can reduce the amount of seat filling material, which is conducive to the realization of lightweight car seats. The raw materials of steel pipes for car seats are mainly processed into one by welding. The end of some steel pipes is used to be welded vertically with the middle of another steel pipe. The arc-shaped structure in the middle of the steel pipes can ensure a sufficient length of the welded joint bet...
