螺钉旋具的失效,主要是因强韧性不足而产生理性变形或脆性断裂。为提高产品质量,我们对螺钉旋具进行了感应加热淬火工艺试验,并已投入生产。现将我厂的试验及生产应用情况介绍如下。 1.工艺试验试验材料为45钢,试样厚度为5mm。感应加热采用GP60-CR13-1型高频装置。用螺旋型及平面型两种连续加热感应器。但用螺旋状感应器时,螺钉旋具刀头的
Screw screw failure, mainly due to lack of strength and flexibility and produce a rational deformation or brittle fracture. In order to improve the product quality, we have carried on the induction heating quenching craft experiment to the screw screwdriver, and has put into production. Now my factory test and production applications are described below. 1. Process test The test material is 45 steel, the sample thickness is 5mm. Induction heating using GP60-CR13-1 high-frequency devices. With spiral and planar two kinds of continuous heating sensor. However, with a spiral sensor, the screw screwdriver bit
