A process for removing residual burrs in fine-blanking parts of small teeth

Abstract

The invention discloses a process of removing residual burrs in a toothlet fine blanking part tooth. The process particularly comprises the following steps: placing a plurality of toothlet fine blanking parts, on the surfaces of which burrs are removed in advance, in a part accommodating cavity of a vibrating finisher; adjusting the vibrating finisher to be at a certain vibration frequency; and under the working condition of not adding an abrasive into the part accommodating cavity, keeping the vibrating finisher working for a predetermined time. Compared with a process of removing residual burrs in a toothlet fine blanking part tooth by means of shot blasting in the prior art, the process provided by the invention utilizes meshing collision between part teeth to remove the residual burrsin the part teeth, is higher in efficiency and lower in cost, can not only cause no damage to the appearance quality of the parts but also improve the surface finish degree of the parts, and leads tono environmental pollution in the process.

Description

technical field [0001] The invention relates to the technical field of removing burrs in teeth of small fine-blanking parts, in particular to a process for removing residual burrs in teeth of fine-blanking parts of small teeth. Background technique [0002] Small tooth fine blanking parts will inevitably produce thorns, that is, burrs, on the edge of the part during fine blanking, especially the burr height in the tooth area is relatively large. Burrs will directly affect product quality, so parts are usually deburred by deburring machines or manual grinding. [0003] Due to the special structure of tooth parts, when removing the burrs on the side surface of fine blanking parts, some burrs will remain inside the tooth grooves, which seriously affects the product performance. Therefore, after removing the burrs on the side surface of fine blanking parts, it is also necessary to remove the burrs remaining inside the alveoli. At present, the main method for removing burrs insi...

AI Technical Summary

Problems solved by technology

[0004] Although the shot peening process can remove some burrs, it has relatively large defects, which are as follows: due to the extremely fast speed of the shot peening, it is easy to cause damage to the surface of the part and the inside of the tooth, affecting the appearance quality of the part and product performance. The dust generated during pilling can make the environmental dust concentration reach 200-300mg / m 2 , operators working in such an environment are extremely vulnerable to pneumoconiosis

[0005] In addition, for small fine-blanking parts, the alveolar size is small, and the smallest particle of shot peening is often larger than the alveolar spacing, that is, it is difficult for shot peening particles to enter between the alveoli, which is not conducive to the removal of burrs between the alveoli
