一、概述 板料冲压过程中,在很多情况下同时需要横向的动作,进行横向甚至与滑块运动方向相反的冲压作业。一般包括水平的、与滑块运动方向成任意角度的、自下而上的以及从里向外的各种动作,以满足冲压件横向部位冲压成型及复合冲压工序的需要,例如拉伸件侧壁和底部冲孔、切口、卷边、压波和板料多向弯曲等等,保证冲压零件的相对尺寸精度和形位公差。冷冲模的这种变冲床滑块的垂直运动而成为横向动作的机构,通称为冷冲模的横向动作结构。
First, an overview Sheet metal stamping process, in many cases at the same time the need for horizontal action, horizontal and even the direction of the slider movement opposite stamping operations. Generally includes horizontal, at any angle with the direction of movement of the slider, bottom-up and from the inside out to meet the various needs of stamping stamping parts forming and composite stamping process requirements, such as the tensile member side Wall and bottom punching, incision, curling, buckling and sheet bending multi-direction, etc., to ensure the relative accuracy of the stamping parts and the shape of the tolerance. The cold punch of this variable punch bed vertical movement of the slider into a horizontal movement of the body, commonly known as cold die horizontal movement structure.
