The torsion bar is of a hollow pipe structure, flat faces and through holes are machined in the two ends of the torsion bar, the machining device comprises an upper pressing block and a base, the torsion bar is placed in the middle of the base through a support, the torsion bar is positioned through a right side inner positioning mechanism and a left side inner positioning mechanism, and meanwhile a mandrel serves as an inner die. Outer positioning mechanisms which are symmetrical left and right are placed on the base, and an inner positioning straight rod, an outer positioning straight rod and a plane stamping die are installed on the upper pressing block. During working, the torsion bar is placed on the support, the upper pressing block moves downwards to enable the inner positioning mechanism to move towards the middle until the torsion bar is positioned, then the outer positioning mechanism fixes the outer circumference of the torsion bar, and then the plane stamping die conducts stamping forming on the torsion bar. According to the device, double positioning of the inner die and the outer die is achieved while the torsion bar is positioned, meanwhile, the excess material expansion section is machined on the positioning shaft, the stamping allowance can move in the axial direction, and the machining quality of products and reliable application of the device are guaranteed.

    一种汽车伸缩电动踏板扭力杆及加工装置,扭力杆为空心管结构,两端加工扁平面及通孔,加工装置包括上压块及底座,底座中间通过支架放置扭力杆,通过右侧内定位机构和左侧内定位机构对扭力杆进行定位,同时芯轴作为内模,在底座处放置左右对称的外定位机构,在上压块处分别安装内定位直杆、外定位直杆、平面冲压模。工作时,将扭力杆放置到支架上,上压块下行,向将内定位机构往中间方向运动,直到对扭力杆定位,然后外定位机构将扭力杆的外圆周固定后平面冲压模对扭力杆冲压成型。该装置通过对扭力杆定位的同时,实现内外模的双定位,同时在定位轴处加工余料膨胀段,使得冲压余量可以实现轴向移动,保证产品的加工质量及装置的可靠运用。
