[ detailed description ] embodiments
The present invention will be described in further detail with reference to the following embodiments.
As shown in figure 1, the cutting tool for chipless cutting of the plastic pipe comprises a long-strip-shaped tool body 1, wherein the thickness a of the tool body is 4.5-5.5 mm. The front end of the cutter body 1 is provided with a top cutter part 2 and a side cutter part 3 which are used for sharpening, as shown in figure 2, the cutting edge of the top cutter part 2 comprises a top cutter cut-in part 4 and a top cutter expansion part 5, the depth b of the top cutter cut-in part is 2.3-2.7 mm, and the width c of the top cutter cut-in part is 2-2.3 mm. The length d of the cutting part of the top knife is 12-18 mm. The degree of depth e of top sword portion of expanding the supporting portion is 9 ~ 10mm, be 45 contained angles between side sword portion 3 and the top sword portion 2, as shown in fig. 3, the blade of side sword portion 3 includes side sword cutting part 6 and side sword portion of expanding the supporting 7, the degree of depth f of side sword cutting part is 1.8 ~ 2.2mm, the width g of side sword cutting part is 1.8 ~ 2.2 mm. The depth h of the side cutter expanding part is 9.5-10.5 mm. The angles of two side surfaces of the top knife expansion part 5 are smaller than the angles of two side surfaces of the top knife cut-in part 4; the angles of the two side surfaces of the side cutter expanding part 7 are smaller than the angles of the two side surfaces of the side cutter cutting part 6.
The utility model discloses a theory of operation is: the whole cutting process to plastics tubular product, actually be the cutting of extrusion formula, the most advanced body that gets into of the portion of cutting into of the department of meeting of its top sword portion 2 and side sword portion 3 makes the body cut open an incision, this incision is crowded gradually into to top sword expansion portion 5 and side sword expansion portion 7 after that, the limit is cut into and is expanded the support, until the body of plastics tubular product is cut off, whole tub process of cutting is progressive, there can not be the smear metal, and because the both sides face angle of expansion portion is less than the both sides face angle of cutting into the portion, so the cutting plane of tubular product can not exist the turn-ups.
