The utility model relates to a multi-point forming device and a multi-point zoning method for partitioned pressing sheet metal, which belongs to the field of mechanical engineering technology. The purpose of the utility model is to change the current situation that blank holder and trimming process are needed when forming sheet metal with integral die, overcome the shortcomings of easy wrinkling of workpiece or low utilization rate of material when forming sheet metal with multi-point digital die, and provide a multi-point forming device and a multi-point zoning method of partitioning pressing sheet metal with wrinkle-proof function. The upper unit fixing seat of the utility model is divided into the first group of fixing seats, the second group of fixing seats, the third group of fixing seats and the fourth group of fixing seats in turn. A plurality of basic units are installed on the first group of fixing seats, the second group of fixing seats, the third group of fixing seats and the fourth group of fixing seats, and a plurality of oscillating punches are installed at the end of each basic unit. Basic unit. Compared with the integral die forming, the utility model can realize the die-free and blank holder-free forming of the three-dimensional surface of sheet metal, save the design, manufacture and debugging process of the die and the contour process of the cutting workpiece after the sheet metal forming, greatly shorten the production preparation period, save the materials, tools, energy and time for manufacturing the die, and improve the utilization rate of the sheet metal.

分区压制式板材多点成形装置
本技术属于机械工程
技术介绍
目前,板材的三维曲面成形主要采用整体模具或多点式数字化模具来实现。薄板或复杂形状的三维曲面件成形时,一般都需要压边机构来防止起皱;导致模具结构复杂,还降低板材利用率,而且在成形后需要增加切边工序。这样,使用整体模具成形一个工件往往需要一套或多套模具,增加制模费用和调模时间。如果使用多点式数字化模具,虽然能够利用很多高度可调的基本体单元柔性改变成形面的形状,实现一模多用的功能,降低制模费用;但是需要解决被加工件的起皱问题。专利名称为“板材多点成形装置”(中国专利号:ZL02109866.2)的技术专利在上下基本体群的四周设有压边装置,采用多个液压缸对压边圈施加压力,解决了柔性压边问题;但仍然需要成形后的切边工序,而且成形小尺寸工件时需要采用远大于实际所需尺寸的板材来实现压边成形。专利名称为“具有防皱功能的板材多点成形装置”(中国专利号:ZL201110162679.0)的技术专利由调形单元、夹料单元、单元固定板及加载机构组成,其调形单元和夹料单元交错排列,多个高度可调的调形单元通过调形机构改变其包络面形状,取代传统实体模具;多个被动移位的夹料单元通过背压作用夹持板材,取代压边机构;获得了较好的防皱效果,但需要进一步的改进与完善。分区压制式板材多点成形装置由若干个成形区域和很多基本体单元组成,能够通过分区域压制成形方式,抑制成形过程中产生的皱纹,并减小板材成形后的回弹。
