通风座冲压工艺分析及拉深模设计
摘要
冲压是通过模具对板材施加压力或拉力,使板材塑性成型,有时对板材施加剪切力而使板材分离,从而获得一定尺寸、形状和性能的一种零件加工方法。由于冲压加工经常在材料冷状态下进行，因此也称冷冲压。冲压加工的原材料一般为板材或带材，故也称板材冲压。冲压加工需要研究冲压工艺与模具两个方面的问题。冲压工艺可以分为分离工序和成形工序。而分离工序又有落料、冲孔、切断、切边、剖切等工序；成型工序又包括卷圆、扭曲、拉深、变薄拉深、翻孔、翻边、拉弯、胀形、起伏、扩口、缩口、旋压、校形等。
本次课题为通风座冲压工艺分析及拉深模设计，冲压加工的材料利用率较高，一般可达70%~85%，冲压加工的能耗低，由于冲压生产具有节材、节能和高生产率等特点，所以冲压件呈批量生产时，其成本比较低，经济效益较高。

Abstract
Stamping is a kind of part processing method, which can make the sheet plastic forming by applying pressure or pull through the mold to make the sheet plastic, and sometimes separate the plate by applying shear force to the plate, so as to obtain a certain size, shape and performance. Because stamping is often carried out under the condition of cold material, it is also called cold stamping. The raw materials for stamping are usually sheet or strip, so it is also known as sheet stamping. Stamping process needs to study two aspects of stamping process and die. Stamping process can be divided into separation process and forming process. The separation process includes blanking, punching, cutting, cutting, cutting and cutting. The forming process includes roll circle, twist, drawing, thinning, turning, flanging, bending, expansion, undulation, expansion, contraction, spinning, alignment, etc.
This subject is the stamping process analysis and drawing die design for the ventilation seat. The material utilization ratio of stamping is high, it can reach 70%~85%, the energy consumption of stamping is low. Because the stamping production has the characteristics of material saving, energy saving and high productivity, the cost is low and the economic benefit is high when the stamping parts are produced in batch production.
Key words stamping process; ventilating seat; stamping process; drawing die
