Abstract

The utility model discloses a three sword wolfram steel shaping swoves, including tool bit and handle of a knife, its characterized in that: be equipped with the sword neck between tool bit and the handle of a knife, be equipped with three cutting base on the tool bit, it is three cutting base is last all to include knife face behind rake face, major first flank and the second, major first flank and the crossing side cutting edge that forms of rake face, the cutting base top is equipped with knife face behind the end tooth, the crossing end sword that forms of knife face and rake face behind the end tooth, be equipped with the chip groove that extends to the sword neck between three cutting base's the side cutting edge. The beneficial effects of the utility model are that: the tool bit has the sword neck to do benefit to the drainage with the design of cutter body coupling part to prevent to hit the sword, every tooth of tool bit all has a back knife face, reduces the cutting surface's of cutter and work piece friction, does benefit to the chip removal, and cutter side cutting edge is spline curve, and the processing part once takes shape, changes the cutter when having avoided processing non -standard part many times, improves production efficiency, and it is the potential safety hazard that produces to have reduced the change cutter.

Description

A kind of three sword tungsten steel forming knifes
Technical field
Utility model is related to the cutting tool field of industrial processes, more particularly to a kind of three swords tungsten steel forming knife.
Background technology
In machining, cutter is the indispensable critical piece of machine tooling, and the quality of cutter quality has influence on itself Service life, also have influence on the quality and production efficiency of machining.When being processed to the nonstandard part of processing, need Many process tools are changed, production efficiency is reduced, processing effect does not reach requirement yet, cutting speed is slow, chip removal has some setbacks etc. asks Topic, while exchanging knives process also add potential safety hazard.
The content of the invention
Goal of the invention of the present utility model is:There is provided a kind of fast with cutting speed and be beneficial to chip removal, improve processing smart Degree, without the need for repeatedly changing three sword tungsten steel forming knifes of different cutters.
The technical solution adopted in the utility model is such:A kind of three sword tungsten steel forming knifes, including cutter head and handle of a knife, its It is characterised by:Knife neck is provided between the cutter head and handle of a knife, and the cutter head is provided with three cutting seats, on three cutting seats Include knife face after rake face, major first flank and second, the major first flank is crossed to form side cutting edge, institute with rake face Stating and knife face after end tooth is provided with the top of cutting seat, after the end tooth, knife face and rake face are crossed to form end sword, three cuttings seat Side cutting edge between be provided with the chip area for extending to knife neck.
The side cutting edge is SPL.
First relief angle of end sword of the end sword is 6 °, and end angle of cutting edge is 7 °, and first relief angle of side cutting edge is 12 °, the Two relief angles are 28 °.
Chamfering is provided between the knife neck and handle of a knife, and the angle of the chamfering is 30 °.
The three swords tungsten steel forming knife generally wolfram steel material.
In sum, as a result of above-mentioned technical proposal, the beneficial effects of the utility model are:Cutter head is connected with cutter hub Part is designed with knife neck beneficial to excretion, and prevents from hitting knife, cutter head each tooth have one after knife face, reduce cutter with workpiece The friction of cutting surface, beneficial to chip removal, and to avoid the nonstandard part of processing be repeatedly to change cutter, improve production efficiency, drop Low cutter of changing is the potential safety hazard for producing.

Labelling in figure:1 is handle of a knife, and 2 is cutter head, and 3 is knife neck, and 4 are cutting seat, and 5 is rake face, and 6 is major first flank, 7 For knife face after second, 8 is knife face after end tooth, and 9 is side cutting edge, and 10 is chip area, and 11 are end sword, and 12 is chamfering.
Specific embodiment
Below in conjunction with the accompanying drawings, this utility model is described in detail.
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement Example, is further elaborated to this utility model.It should be appreciated that specific embodiment described herein is only to explain This utility model, is not used to limit this utility model.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of three swords tungsten steel forming knife, including cutter head 2 and handle of a knife 1, cutter head 2 and handle of a knife Knife neck 3 is provided between 1, and cutter head 2 is provided with three cutting seats 4, includes rake face 5, major first flank 6 on three cutting seats 4 With second after knife face 7, major first flank 6 is crossed to form side cutting edge 9 with rake face 5, is provided with knife face after end tooth at the top of cutting seat 4 8, after end tooth, knife face 8 and rake face 5 are crossed to form end sword 11, be provided with and extend to knife neck between the side cutting edge 9 of three cutting seats 4 3 chip area 10, side cutting edge 9 are SPL, and cutting edge the first relief angle in side is 12 °, and the second relief angle is 28 °, knife neck 3 and knife Chamfering 12 is provided between handle 1, and the angle of chamfering 12 is 30 °, three sword tungsten steel forming knifes generally wolfram steel material.
During work, the afterbody of mechanical grip cutter hub, forming cutter are rotated around central shaft, 2 cutting workpiece of rotary cutter, workpiece Shape is formed at forming cutter and reverses cambered surface, and the chip of cutting leaves cutter hub along chip area.
Preferred embodiment of the present utility model is the foregoing is only, it is not to limit this utility model, all at this Any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in this utility model Protection domain within.
