我厂133车间水压穿孔机底坐底平面,由于长期磨损倾斜已达2～4毫米。这是一台立式水压穿孔机,底坐重量约50吨,底平面在地平面以下1.2米左右的坑内,左右是机架,前后是基础壁和深坑,因此底坐磨损倾斜后要在现场加工修复极为困难。长期以来由于底坐倾斜穿孔机柱塞与底平面不垂直,造成穿孔歪斜,轧出的钢管壁厚不均,产品质量差,工具消耗量也很 I workshop 133 hydraulic pressure piercing machine at the end of the plane, due to long-term wear and tear has reached 2 to 4 mm. This is a vertical hydraulic punching machine, sitting at the end of weighing about 50 tons, the bottom plane in the ground about 1.2 meters below the pit, left and right is the rack, front and rear are the foundation wall and pit, so the base sit wear tilt In the field of processing and repair extremely difficult. For a long time due to sit at the end of the tilt perforation machine plunger and the bottom plane is not vertical, resulting in perforation skew, rolled steel pipe wall thickness, product quality is poor, the tool consumption is also very
