Abstract
The present invention relates to the field of cutting tools, and in particular relates to a plastic material processing cutter used for performing one-step molding to the PC plastic material. The cutting tool comprises a cutter bar made from a high-speed steel material, and the end of the cutter bar is welded with a cutter head made from a hard alloy material. A cutter edge is arranged on the outer side surface of the cutter head, a strengthened layer is coated on the surface of the cutter edge, and the cutter edge comprises a first cutter edge, a second cutter edge and a third cuter edge, wherein the first cutter edge is a conical surface which is connected with the cutter bar and has a radius reduced gradually, the second cutter edge is an arc-shaped surface with a radius being 0.25mm, and the third cutter edge is an arc-shaped surface with a radius being 0.35mm. After tempered in a tempering furnace, the cutter is cooled in quartz sands. The beneficial effects of the cutter are that: by using the cutter, a workpiece with three hierarchies of different shapes can be processed; and the processing efficiency is high and the surface smoothness is good.
Description
Technical field
The present invention relates to the cutter field, particularly a kind of the PC plastic material is carried out one-time formed processing plastic material cutter.
Background technology
The PC plastic material is being added man-hour, usually the machined surface that requires for difformity needs to adopt different cutters to process, and need to repeatedly process the processing that just can finish workpiece like this, operating efficiency is very low, large, the stratum of some change of shape more workpiece that distributes particularly, adding man-hour need to be with different tool sharpenings repeatedly, and the centre may also need tool changing, efficient is very low, and finished surface is discontinuous, and fineness is relatively poor, can't satisfy the requirement of machining accuracy.
Summary of the invention
During the workpiece that the object of the invention is to distribute more for processing stratum in the prior art described in the background technology, efficient is low, workpiece machining surface is discontinuous, the problem that fineness is relatively poor provides a kind of a kind of processing plastic material cutter that can disposablely process the coherent workpiece with three stratum of any surface finish.
The technical scheme that can realize goal of the invention of the present invention is as follows:
A kind of processing plastic material cutter, it comprises the knife bar of high speed steel material, the knife bar end is welded with the cutter head of Hardmetal materials, described cutter head lateral surface is provided with blade, blade surface is coated with strengthening layer, described blade comprises the first blade, the second blade and the 3rd blade, the first blade is the diminishing taper surface of radius that is connected with knife bar, the second blade is that radius is the arcwall face of 0.25mm, the 3rd blade is that radius is the arcwall face of 0.35mm, this cutter allows as cooling off in the quartz sand carry out tempering in tempering furnace after.
Described strengthening layer is tungsten alloy.
Beneficial effect of the present invention is for can process the workpiece with three difform stratum, and working (machining) efficiency is high, and processed surface smoothness is good.
Description of drawings
Fig. 1 is schematic diagram of the present invention;
Fig. 2 is the A section enlarged diagram of Fig. 1;
Among the figure, 1 is knife bar, and 2 is cutter head, and 3 is the first blade, and 4 is the second blade, and 5 is the 3rd blade.
The specific embodiment
As depicted in figs. 1 and 2, a kind of processing plastic material cutter, it comprises the knife bar 1 of high speed steel material, knife bar 1 end is welded with the cutter head 2 of Hardmetal materials, described cutter head 2 lateral surfaces are provided with blade, blade surface is coated with strengthening layer, described blade comprises the first blade 3, the second blade 4 and the 3rd blade 5, the first blade 3 is the diminishing taper surface of radius that is connected with knife bar 1, the second blade 4 is the arcwall face of 0.25mm for radius, and the 3rd blade 5 is the arcwall face of 0.35mm for radius; Described strengthening layer is tungsten alloy, and this cutter allows as cooling off in the quartz sand carry out tempering in tempering furnace after.
Claims (2)
1. processing plastic material cutter, it is characterized in that: it comprises the knife bar of high speed steel material, the knife bar end is welded with the cutter head of Hardmetal materials, described cutter head lateral surface is provided with blade, blade surface is coated with strengthening layer, described blade comprises the first blade, the second blade and the 3rd blade, the first blade is the diminishing taper surface of radius that is connected with knife bar, the second blade is that radius is the arcwall face of 0.25mm, the 3rd blade is that radius is the arcwall face of 0.35mm, this cutter allows as cooling off in the quartz sand carry out tempering in tempering furnace after.
