Movable steel cutting jig frame

The utility model discloses an adjustable steel cutting jig frame which comprises a cuboid frame. The cuboid frame comprises a long-side frame and a short-side frame; a plurality of angle steel assemblies are arranged on the sides of the front and rear long-side frames; the angle steel assembly comprises two adjacent angle steels; and a gap is reserved between the two pieces of angle steel to form a slot for mounting a tire piece. The distance between every two adjacent inserting grooves is set to range from 110 mm to 120 mm. The tire piece can be used on the two sides and replaced independently, cost is greatly reduced, safe and stable operation of part cutting is guaranteed, and convenience and rapidness are achieved; and by setting the distance between the inserting grooves, the jig frame supporting device can be suitable for cutting parts with irregular gravity centers. 本实用新型公开一种活络式钢材切割胎架，包括长方体式框架；所述长方体式框架包括长边框架以及短边框架；前后两个长边框架侧设置有多个角钢组件；所述角钢组件包括相邻的两个角钢；所述两个角钢之间留有间隙，形成安装胎片的插槽。相邻两个插槽间距设置为110mm-120mm。本实用新型可实
