Description

双曲面折弯机构
技术领域
本实用新型涉及一种金属板材折弯设备，特别的涉及金属板折弯机配合使用的模具装备。
背景技术
金属板折弯操作是机械加工中的常见工序，由工人操作折弯机来完成。折弯机品种多样，有液压折弯机和数控折弯机，按运动方式可分为上动式、下动式。折弯机包括支架、工作台和夹紧板，工作台置于支架上，工作台由底座和压板构成，底座通过铰链与夹紧板相连，底座由座壳、线圈和盖板组成，线圈置于座壳的凹陷内，凹陷顶部覆有盖板。使用时由导线对线圈通电，通电后对压板产生引力，从而实现对压板和底座之间薄板的夹持。
折弯机可以通过更换折弯机模具对不同形状的工件进行折弯加工。通常的折弯模具的刀具一股为直刀，折弯线为直线，对于具有圆弧曲面类钣金件的折弯需要无法满足。
实用新型内容
本实用新型的目的在于提供一种结构简单，可以实现双曲面类钣金件的圆弧边缘折弯功能的双曲面折弯机构。
实现本实用新型目的的技术方案是：
一种双曲面折弯机构，具有下折弯模固定板和上折弯模固定板，上述下折弯模固定板上固定连接承力块，承力块上卡接下折弯模，上折弯模固定板固定连接上模连接块，上模连接块下方固定连接上折弯模，且上、下折弯模的配合面为圆弧面。
上述下折弯模包括具有圆弧表面的底模和垂直于底模的侧面靠板。
本实用新型的好处在于上、下折弯模具有圆弧形的配合面，能够在一次折弯中完成双曲面类钣金件的圆弧边缘折弯功能，提高了生产效率。
附图说明
图1为本实用新型的立体结构示意图。
图2为本新型的侧面示意图。
具体实施方式
见图1和图2，本新型双曲面折弯机构具有下折弯模固定板1和上折弯模固定板2，上、下折弯模固定板在使用时分别固定到折弯机上。下折弯模固定板上具有承力块11，承力块上具有切槽，切槽用来卡接下折弯模3，下折弯模包括具有圆弧表面的底模31和靠板32，靠板位于底模侧面并且于底模垂直，底模和靠板组合成下模折弯刀。
上折弯模固定板2下方设有上模连接块21，上模连接块下方固定连接上折弯模4，上折弯模与下折弯模配合，且具有圆弧形贴合面。工作时将双曲面类钣金件放入上、下折弯模之间，再由折弯机施加压力，即可实现双曲面型钣金产品的圆弧边缘的折弯功能。

Claims (2)
