Abstract
The invention discloses a boring method of a toughened plastic part. The method comprise the step that a toughened plastic part boring drill is used for machining the toughened plastic part, and the toughened plastic part boring drill comprises a cutting portion, a handle portion, two side main cutting blades, edge blades and grooves; and the main cutting blades and the edge blades axially twist, and the end of the cutting portion is provided with two side transverse blades symmetric with the central line; the cutting portion is made of hard alloy, and the twisting angles between the main cutting blades and the central line range from 12 degrees to 16 degrees; and a machining method comprises the following steps of A, preheating, B, pre-drilling and C drilling. The toughened plastic part boring drill machines the toughened plastic part to be machined. The problems that an existing boring drill inconveniently machines the toughened plastic part, and the machining quality is affected are solved.
Description
Technical field
The present invention relates to plastic apparatus manufacturing technology field, especially a kind of bore bit for processing tempering working of plastics.
Background technology
The bore bit of existing boring machine, generally comprise cutting portion and shank, neck is also had between cutting portion and shank, cutting portion comprises the symmetrically arranged both sides main cutting edge with center line, the side of main cutting edge is provided with rib sword on one side, groove is provided with before two main cutting edges, main cutting edge and the equal axial torsion of rib sword, the termination of cutting portion is provided with the symmetrically arranged both sides chisel edge with center line, the windup-degree of standard and the length of cutting portion are certain relation, but, for the toughened plastic part of processing through tempering process, stress due to working of plastics is concentrated excessive, this bore bit is sharp not, find after deliberation, that the angle that main cutting edge and center line reverse is excessive, and the material of unit-type drill head generally uses as various high-speed steel such as HSS, hardness is also inadequate, have impact on crudy, the drill bit of this class standard, is not suitable for processing tempering working of plastics.Thus the method for boring hole designing a kind of applicable processing tempering working of plastics is needed, to meet the demand in market.
Summary of the invention
Problem to be solved by this invention is to provide a kind of toughened plastic part method for boring hole, is not suitable for processing tempering working of plastics, affects the problem of crudy to solve existing method for boring hole.
In order to solve the problem, technical scheme of the present invention is: this toughened plastic part method for boring hole comprises a kind of toughened plastic part bore hole of use and bores a kind of toughened plastic part of processing, described toughened plastic part bore hole bores and comprises cutting portion and shank, neck is also had between described cutting portion and described shank, described cutting portion comprises the symmetrically arranged both sides main cutting edge with center line, the side of described main cutting edge is provided with rib sword on one side, groove is provided with before two described main cutting edges, described main cutting edge and the equal axial torsion of described rib sword, the termination of described cutting portion is provided with and described center line symmetrically arranged both sides chisel edge, the material of described cutting portion is carbide alloy, the windup-degree of described main cutting edge and described center line at 12 ° within the scope of 16 °,
Its processing method comprises the following steps:
A: preheat: band toughened plastic part to be processed is carried out preheating, and heating-up temperature is 115 ° of C ~ 130 ° C, cross-sectional area every 10 square millimeters 50 minutes ~ 60 minutes;
B: preboring: toughened plastic part to be processed is carried out preboring with core drill;
C: enter to bore: bore toughened plastic part machine-shaping to be processed with described toughened plastic part bore hole.
In technique scheme, more specifically scheme can be: the material of described cutting portion is diamond.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, this toughened plastic part method for boring hole has selected a kind of special toughened plastic bore hole to bore, and it adopts 12 ° to the windup-degree of the main cutting edge within the scope of 16 ° with center line, and make drill bit sharper, while is unlikely to angle too small again and makes the easy fracture of sword; Whole cutting portion adopts the Hardmetal materials or diamond that intensity is larger, makes drill bit both meet the requirement of intensity, easily not crisp because of much higher hard again;
2, this method in order to the plastic impact toughness eliminated through tempering process lower, but forming residual stress is higher, crackly phenomenon, preheats and prebored hole before boring, to ensure crudy.
