Problems solved by technology

[0002] When using a conventional nesting knife, when the tool bores through the surface of the part, the residual material in the middle of the machining is extremely easy to stay inside the nesting knife, and it is usually necessary to artificially pull out the residual material from the nesting knife, or even due to internal residual material. Interference in machining results in the scrapping of both the part and the nesting knife

Abstract

The invention discloses an automatic pushing mechanism of a trepanning cutter. The automatic pushing mechanism comprises a cutter body and a cutter handle, a plurality of trepanning blades are arranged on the side edge of the end, away from the cutter handle, of the cutter body, the trepanning blades are fixedly connected with the cutter body through cutter blocks, a plurality of chamfering blades are arranged in the middle of the side edge of the cutter body, a through groove is formed in one end of the interior of the cutter body, a sliding sleeve is arranged in the through groove, a sliding shaft is arranged in the middle of one end of the sliding sleeve, a spring is arranged on the sliding shaft in a sleeving mode, a lining is arranged at one end of the interior of the through groove, and a pushing block is arranged at the end, away from the lining, of the sliding shaft. The automatic pushing mechanism has the beneficial effects that when the trepanning cutter is about to bore a part, the automatic pushing mechanism can accurately push machined middle residues out of the trepanning cutter, adverse effects of the residues on follow-up machining and the trepanning cutter are avoided, the auxiliary operation time can be effectively shortened, the loss of the cutter is reduced, the production efficiency is improved and the production cost is reduced for customers.

Description

technical field [0001] The invention relates to the technical field of nesting knives, in particular to an automatic pushing mechanism for nesting knives. Background technique [0002] When using a conventional nesting knife, when the tool bores through the surface of the part, the residual material in the middle of the machining is extremely easy to stay inside the nesting knife, and it is usually necessary to artificially pull out the residual material from the nesting knife, or even due to internal residual material. Process disturbances lead to the scrapping of both the part and nesting knives. [0003] Aiming at the problems in the related technologies, no effective solution has been proposed yet. Contents of the invention [0004] Aiming at the problems in the related art, the present invention proposes an automatic material pushing mechanism of the nesting knife to overcome the above-mentioned technical problems existing in the related art.
