Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of part trimming, more particularly to a casting part automatic trimming machine. BACKGROUND

[0002] In modern manufacturing, casting is a widely used metal forming process that involves pouring liquid metal into a mold and allowing it to cool and solidify to form the desired part shape. With the continuous development of the casting industry, in order to deal with the excess material generated during the part casting process, such as flash, burrs and irregular surfaces, an automatic trimming machine is configured to work with the casting end to ensure that the part meets the design requirements and quality standards.

[0003] The automatic trimming machine on the market usually uses mechanical cutting method to work, specifically, the part is placed in a fixed clamp, and the high-precision positioning system ensures the accurate position. Then, the high-speed rotating blade performs full-automatic servo trimming on the part in the clamp, and then the part surface is treated by mechanical scraping, grinding or polishing to remove the remaining burrs. At the same time, in order to further optimize the quality of the part cutting surface, some equipment is also equipped with an intelligent control system, which can automatically adjust the deburring parameters according to the material and shape of the part to ensure the best processing effect.

[0004] However, in actual operation, the automatic trimming machine can meet the existing requirements and quality standards for ordinary block parts, but when casting pipe-shaped parts, due to the particularity of the cutting surface, flash and burrs will be generated on the inner wall edge, outer wall edge and cutting surface during the cutting process. The mechanical scraping mechanism of the existing trimming machine cannot simultaneously optimize the processing of the three end surfaces. The existing processing scheme either controls the scraping end to process multiple times and multiple angles through the intelligent control system, or uses electrolytic reaction to dissolve the impurities on the part cutting surface, which not only wastes time and effort, but also makes the casting production line complicated and difficult to control.

[0070] ​Then, after the second sharp mouth scraper 712 on both sides is attached to the outer surface and the inner circular wall of the pipe, the second multi-stage adjustment module 4 can be controlled to rotate as a whole by the servo drive of the first servo motor 21 to process the section around the arc of the pipe. During the processing, the second sharp mouth scraper 712 can be further pressed by the rotation of the output end of the third servo motor 44, so that the end face of the second sharp mouth scraper 712 is lifted and inflated, the outer top sleeve 7113 is squeezed into the inside of the sealed cavity 7111, and the linkage outer extension rod 7114 on one side stored in the sealed cavity 7111 is extended. Once the linkage outer extension rod 7114 is extended, it will push the first piston sleeve plate 714 in the inflation chamber 710 in the cavity housing 73 towards the inflation conduit 79, which is similar to the inflator in the prior art. After the gas is pumped into the inflation conduit 79 on both sides, the one-way valve cover 713 is pushed outward, and the gas enters the cavity of the storage box 77 through the second ventilation slot 716;

[0071] With the reciprocating rotation of the first gear disc 45 of the third servo motor 44, the second sharp mouth scraper 712 reciprocally pulls the first piston sleeve plate 714 in the inflation chamber 710, continuously pumps the gas into the inside of the storage box 77, increases the gas pressure in the storage box 77, and pushes the second piston sleeve plate 717 in the storage box 77 to extrude the liquid stored inside through the liquid guide conduit 718 into the atomizing nozzle 715 in the inwardly inclined air guide frame 75 on both sides.

[0072] At this time, by opening the servo fan 76 outside the platform partition plate 72, the atomized reagent can be blown to the two sides of the pipe by the wind blown by the servo fan 76. Only the storage of metal multifunctional reagent in the storage box 77 on both sides is needed, so that the atomized reagent can be directly acted on the section with the scraping end. It is suitable for metal parts, especially parts with multiple steps. Since the metal multifunctional reagent contains lubricant, abrasive particles and polishing components, deburring, grinding and polishing can be completed in one operation, further improving the effect of section processing, and the servo fan 76 can also blow air outward through the inwardly inclined air guide frame 75 before the second sharp mouth scraper 712 is reciprocally pressed and the atomized reagent is sprayed.

[0073] Since the scraping force and the spraying of the auxiliary reagent of the whole structure are controlled by the third servo motor 44, the interference problem of the multi-drive mechanism during operation is reduced, and the fault tolerance of the linkage end is improved.
