Process for removing burrs on surface of thin-wall part

Abstract

The invention discloses a process for removing burrs on the surface of a thin-wall part. The process is characterized by including the following steps that the part is connected with the positive pole of a direct current power supply to form an anode, a forming tool is connected with the negative pole of the direct current power supply to form a cathode, and the gap of 0.05-1.2 mm is kept between the anode and the cathode, so that a circulating neutral inorganic salt solution flows; when the anode and the cathode are immersed into the neutral inorganic salt solution and direct currents are led into the solution, the burrs protrude from the surface of the thin-wall part for 0.02-2 mm, and the burrs are dissolved until all the burrs are dissolved and the edges of the part gradually become circular beads. According to the process for removing the burrs on the surface of the thin-wall part, the process is simple, and through strict process parameter control, the burr removing speed is high, part base body damage can be reduced, and pollution can be reduced.

Description

Technical field [0001] The invention belongs to the field of surface treatment, in particular to a process for removing burrs on the surface of thin-walled parts. Background technique [0002] The burrs produced in the manufacturing process of thin-walled parts have adverse effects on the accuracy, use, reprocessing positioning, operation safety and appearance quality of the parts. At the same time, because deburring takes a lot of time and expense, it has become one of the biggest obstacles to cost reduction. The prior art process method for removing burrs on thin-walled parts adopts grinding wheel to polish and remove, and manually controls the polished surface, which has the disadvantages of low efficiency, serious damage to the part matrix, environmental pollution and the like. This method of removing burrs has certain disadvantages, which reduces the bright band of the effective contact surface of the stamping section, affects the contact area of ​​the part and other parts,...

Problems solved by technology

At the same time, because deburring takes a lot of time and money, it has also become one of the biggest obstacles to reducing costs.

The prior art method for removing burrs from thin-walled parts uses grinding wheels to remove the burrs, and manually controls the polished surface, which has the disadvantages of low efficiency, serious damage to the part matrix, and environmental pollution.

This method of deburring has certain shortcomings, which reduces the bright band of the effective contact surface of the stamping section, affects the contact area between the part and other parts, and affects the wear resistance of the part.
