拖板冲压Tag内容描述:
1、牵引车拖板支架改造及加固,汇报人:黄翠聪,项目开展前现状:,目前三部牵引车挡板支架都出现不同程度严重损坏,主要原因是拖板常年停靠在外,风吹雨淋,拖板支架生锈、断裂、油漆脱落,叉车工在盘酒时,车辆运载酒垛。

5、Characteristics and Sheet Metal Forming1 The article overview Stamping is a kind of plastic forming process in which a part is produced by means of the plastic forming the material under the action of a die. Stamping is usually carried out under cold state, so it is also called stamping. Heat stamping is used only when the blank thickness is greater than 8100mm. The blank material for stamping is usually in the form of sheet or strip, and therefore it is also called sheet metal forming. Some n。
6、冲压成形与板材冲压 1 概述通过模具使板材产生塑性变形而获得成品零件的一次成形工艺方法叫做冲压。由于冲压通常在冷态下进行,因此也称为冷冲压。只有当板材厚度超过 8100mm 时,才采用热冲压。冲压加工的原材料一般为板材或带材,故也称板材冲压。某些非金属板材(如胶木板、云母片、石棉、皮革等)亦可采用冲压成形工艺进行加工。冲压广泛应用于金属制品各行业中,尤其在汽车、仪表、军工、家用电器等工业中占有极其重要的地位。冲压成形需研究工艺设备和模具三类基本问题。板材冲压具有下列特点: (1)高的材料利用率。(2)可加工薄。
