Problems solved by technology

At present, although the chemical deburring technology can effectively improve the deburring effect of the sewn parts, the effect is not obvious in terms of improving the surface brightness of the sewn parts and the mechanical strength of the parts; in addition, the chemical deburring technology used Most of the chemical deburring fluids contain nitric acid, and nitrogen oxide gas is produced during the production process, which seriously pollutes the environment and damages the health of operators.

Embodiment 1

[0019] The specific processing method is as follows:

[0020] a) Pretreatment of sewing parts, the specific treatment process is: first prepare an alkaline cleaning solution, which is prepared from the following ingredients by weight percentage: sodium phosphate 8%, sodium dihydrogen phosphate 2%, sodium silicate 5%, 1% sodium alkylbenzene sulfonate, 84% water; then put the sewing parts into the alkaline cleaning solution, stir the cleaning solution slightly at a stirring speed of 10 times / min for 3 minutes, and fully remove the grease on the surface of the sewing parts ; Then take out the sewing parts from the alkaline cleaning solution, wash the cleaning solution on the sewing parts with clean water; finally dry the sewing parts with a dryer at a temperature of 40 °C.

[0021] b) To prepare deburring solution, weigh 40% hydrogen peroxide, 36% citric acid, 20% malonic acid, 3% sulfuric acid, and 1% combined additives by weight percentage, and put them into a ceramic container...

Abstract

The invention provides a deburring method for joint accessories. The joint accessories are made of high-carbon steel materials. The deburring method includes the following steps of (a) pre-treatment of the joint accessories, (b) preparation of deburring liquid, (c) chemical deburring treatment and (d) post-treatment of the joint accessories. The deburring method is easy and convenient to operate, environmentally friendly and efficient, obviously lowers the surface roughness of the accessories, improves the surface brightness of the accessories, and greatly improves the mechanical strength of the accessories.

Description

technical field [0001] The invention relates to a deburring method, in particular to a deburring method for sewn parts, and belongs to the technical field of mechanical processing. Background technique [0002] Burrs are the most common by-products in mechanical processing. During the processing of sewing parts, burrs are inevitably accompanied by the generation of burrs. Removing burrs can not only improve the processing accuracy and assembly accuracy of parts, but also change the use of parts. Performance and improve the service life of parts, improve the appearance quality and the impact of parts on the safety of workers during use, and even help to improve the reliability and stability of the entire mechanism during use, reduce manufacturing costs, and bring huge benefits to the factory economic benefits. [0003] The current technologies for deburring sewing parts include: mechanical polishing deburring, thermal energy deburring, ultrasonic deburring, electrochemical d...
