Abstract
The processing method of tapered aperture stainless steel, workpiece is installed on the drilling machine, select the drill bit graded drilling of different-diameter for use according to the aperture, outside diameter from big to small, an end big to taper hole bores first order hole, dwindles step by step, when surpassing drill bit length as if hole depth length again, the tune of will working is inwardly bored the afterbody hole from little taper hole one end, until drilling through; Then by the processing of line cutting carrying out tapering; With plug taper hole is ground again.The present invention adopts conventional equipment, graded drilling, shunting machine-shaping.
Description
The present invention relates to the processing method of tapering small-bore, be specially adapted to stainless steel material.
In the small-bore that is processed with tapering, when especially adopting stainless steel material, No. 2 nozzles as in the oil spout steel-making require throw far away; Cloud point is thin, just designs growth 36.5mm, osculum (ejiction opening) aperture 1.2mm, and tapering 1: 100, it not only structurally has specific (special) requirements, and wants intensity height, anti-wear performance good on material, and therefore, desirable material is a stainless steel.If be difficult to realization with common processing method, existing employing laser is processed, the processing charges height according to above-mentioned condition.
The purpose of this invention is to provide a kind of employing conventional equipment, technology is simple, is processed with the method for the aperture stainless steel material of tapering.
The processing method of tapered aperture stainless steel of the present invention is after workpiece is carried out outer wall and two ends processing, then boring, endoporus grinds, and its boring is the drill bit graded drilling that adopts different-diameter, and outside diameter from big to small, an end big to taper hole bores first order hole, until drilling through; Then carry out tapering line cutting processing by wire cutting machine tool; With plug taper hole is ground again.
The processing method of tapered aperture stainless steel of the present invention, its graded drilling are that carry out at two ends, earlier big taper hole one end are begun to hole step by step from big to small, with the workpiece tune, bore minimum one-level hole, until drilling through again; It then is tapering line cutting processing; Plug grinds taper hole.
The processing method of tapered aperture stainless steel of the present invention, by distinct device shunting processing, particularly graded drilling has solved the tapering small-bore, and is the problem of materials processing difficulty such as stainless steel.Graded drilling is to select corresponding drill bit according to the taper hole size, and is more favourable to subordinate's boring by big drill bit subdrilling, but the good every grade of institute's drilling depth of GPRS, speed should not be too fast during brill, and punching is good on drilling machine.Be that classification is holed in addition, when especially hole depth surpasses drill bit length, need tune boring, therefore, to the required precision height of clamping apparatus, want accurately the location.Use the technology of the present invention and have low equipment investment, processing charges is low, and promotional value is big.
Fig. 1 is an embodiment of the invention processing work schematic diagram.
Below in conjunction with the embodiment in the accompanying drawing the technology of the present invention is elaborated.
The processing method of tapered aperture stainless steel of the present invention, shown in the accompanying drawing 1 for No. 2 nozzles in the oil spout steel-making, be stainless steel material, the long L of nozzle is 36.5mm, outlet aperture φ
1Be 1.2+0.012mm, tapering α is 1: 100.At first carry out the processing of outer wall and two ends, then workpiece is installed on the drilling machine, from φ
2End bores first order boring and hole, the second level, then with the workpiece tune, from φ
1End inwardly bores third level hole, and until drilling through, concentricity is wanted accurately; To drill through workpiece again and be installed on the wire cutting machine tool, and carry out tapering line cutting processing, the peace dimensional requirement is slightly put surplus; The back is ground moulding by prefabricated standard plug to taper hole again.
Claims (2)
1, the processing method of tapered aperture stainless steel is that then boring and endoporus ground, and it is characterized in that after workpiece was carried out outer wall and two ends processing:
A, boring are the drill bit graded drillings that adopts different-diameter, outside diameter from big to small, an end subdrilling first order hole big to taper hole dwindles, step by step until drilling through;
B, then tapering line cutting processing;
C, with plug taper hole is ground again.
2, the processing method of tapered aperture stainless steel as claimed in claim 1 is characterized in that:
A, graded drilling are that carry out at two ends, to the boring step by step from big to small of big taper hole one end, with the workpiece tune, bore minimum one-level hole, until drilling through again earlier;
B, tapering line cutting processing;
C, plug grind taper hole.
