High-strength welding clamp surface treatment method

Abstract

The invention discloses a high-strength welding clamp surface treatment method. The high-strength welding clamp surface treatment method comprises the following operation steps that firstly, a hydrochloric acid solution is evenly scattered to the surface of a welding clamp, 10 minutes later, the surface is washed through clean water, and pre-shot blasting liquid is used for being evenly sprayed tothe surface of the welding clamp, wherein the pre-shot blasting liquid is composed of, by weight, 9-13 parts of sodium phosphate, 5-7 parts of ammonium hydroxide, 2-4 parts of benzyl trimethyl ammonium iodide, 1-3 parts of sodium hexafluorophosphate, 4-6 parts of sodium polysulfide and 190-200 parts of water; and secondly, a peening machine is used for spraying ceramic pills to the surface of thewelding clamp, wherein the average diameter of the ceramic pills is 500 microns, the spraying angle is 90 degrees, and the distance between a nozzle and a sample is 180 mm. By means of the high-strength welding clamp surface treatment method, by treating the surface of the welding clamp, the strength of the welding clamp can be effectively improved, the abrasion resisting performance of the welding clamp is greatly improved, and the service life of the welding clamp is effectively prolonged.

Description

technical field [0001] The invention belongs to the field of welding fixture processing and specifically designs a surface treatment method for high-strength welding fixtures. Background technique [0002] In the welding production process, in order to improve product quality and production efficiency, some tools and devices are often used to complete assembly and welding work. We collectively refer to the tools and devices used to clamp and determine the position of the workpiece as welding fixtures. It consists of supports, positioners and clamps. At present, the ordinary welding fixtures on the market have a short service life. Generally, after working for about one year, some uneven shapes will appear on the surface, resulting in inaccurate positioners, and inaccurate and stable shapes and sizes of welding products. Therefore, there is an urgent need for a processing method for improving the wear resistance of the surface of the welding fixture. Contents of the inven...
