Description

一种冲压厚钢板及槽钢的冲模
技术领域:
本实用新型属于钢结构零件的冲压模具技术领域,尤其是一种冲压厚 钢板及槽钢的冲模。 背景技术:
传统的冲压工艺方法,不能满足厚度较大的钢板类和抗弯强度较高的 槽钢类零件的弯曲成形需要,变形难于控制,出现应当变形的部位不符合 设计要求,不允许变形的部位产生明显的变形,成形精度难以满足设计要 求,零件产生明显的凹坑、局部尺寸不符合设计要求,外观质量差,直接 影响整机产品的市场认可。另外施工中工人劳动强度大,产品成本居高不 下。
实用新型内容:
为了解决上述问题本实用新型提供一种冲压厚钢板及槽钢的冲模,可 满足产品弯曲成形的要求。
本实用新型的技术方案是:所述的一种冲压厚钢板及槽钢的冲模,包 括上模、下模,上模紧固在上模座上,所述的下模为二个摆块型下模,下 模通过转轴分别装在下模座上,下模座安装在底座上,在底座的中心轴内 设有通孔,在其中心轴端面固定有挡圈,丝杆的下端装有螺母,丝杆的上 端穿过底座的通孔连接在复位块底部,复位块处于下模座和下模之间的空 腔内,在复位块底部装有弹簧座,弹簧套装在丝杆上。所述的弹簧上端与弹簧座相接触,弹簧下端与挡圈相接触。 本实用新型的特点:在下模的设计中引入摆块成形机构、下部施加弹 性背压技术,使零件从平直状态至成形结束始终和摆块成形机构紧密接触, 处于受控状态,获得良好的外观质量。经过数次行程调节,可确定一个合 理的行程值,以满足产品成形的要求。该冲模既适用于不同设计角度的零 件弯曲成形需要,也适用于不同材质的类似产品。
本实用新型可以保证高抗弯强度零件成形角精度达到士10〃 ,变形区
外侧保证原材料原始平面度,并可使不平直正部分矫正至O.lmm。对于采 用槽钢作为成形主体的零件,受力处的槽钢腿部高度减小量小于0.5mm、 槽钢两腿部最大宽度变化量小于lmm、槽钢腰部无明显突起。本实用新型 使用方便,价格便宜,成本低。 附图说明:
图1是本实用新型的结构示意图。 具体实施方式:
如图1中所示,本实用新型的上模3通过螺栓、垫圈2紧固在上模座1 上,二个摆块型下模4通过转轴5分别装在下模座6上,下模座6安装在 底座13上,在底座13的中心轴内设有通孔,在其中心轴端面固定有挡圈 10,丝杆11的下端装有螺母12,丝杆11的上端穿过底座13的通孔连接在 复位块7底部,复位块7处于下模座6和下模4之间的空腔内可以上下活 动,在复位块7底部装有弹簧座8,弹簧9套装在丝杆11上,弹簧9上端 与弹簧座8相接触,弹簧9下端与挡圈10相接触,在上模3与下模4之间 装有工件14。本实用新型在使用时,先将工件14装在上模3与下模4之间,由冲压
机对冲模进行冲压,此时二个摆块型下模4绕转轴5下压,使复位块7压 縮弹簧9,直到工件14从平直状态至成形结束后,冲压机停止工作并将冲 头上抬,复位块7在弹簧9的弹性力作用下顶着二个摆块型下模4恢复原 位,再对下一个工件14进行冲压加工。
