Technical field

The present invention relates to seamless underwear machine triangle field, refer more particularly to a kind of processing method of seamless underwear machine triangle.

Background technology

All there is process complexity in the processing method of current seamless underwear machine triangle, and the problem that machining accuracy is not high.

Summary of the invention

The object of the invention is to overcome above-mentioned weak point of the prior art and the processing method that the seamless underwear machine triangle that a kind of production technology is simple, machining accuracy is high is provided.

The present invention realizes in the following way:

A processing method for seamless underwear machine triangle, is characterized in that: comprise the following steps:

A, linear cutter: sheet material is pressed the cutting of figure paper size and form triangle body 1;

B, lathe process: triangle body 1 is adopted fixture clamping, the centre bore 2 boring the boss 7 on triangle body 1 and the screw hole 3 of attacking on triangle body 1, the exterior circular column 4 on the triangle of turning simultaneously body 1;

C, peripheral milling are processed: carry out clamping with centre bore 2 and screw hole 3 for benchmark, adopt peripheral milling that the exterior circular column 4 of triangle body 1 is machined to figure paper size, the surface roughness of exterior circular column 4 is Ra1.6, and exterior circular column 4 is 0.1 with the concentricity of screw hole 3;

D, flat stone mill: adopt sanding machine to grind off boss 7, the upper plane of triangle needle tray body 6 of must not damaging; Flat stone mill is adopted to wear into triangle datum level 5 in the bottom surface of triangle body 1, then with triangle datum level 5 for benchmark, triangle needle tray body 6 is milled to figure paper size, and triangle needle tray body 6 surface roughness is Ra0.8, and the upper plane of triangle needle tray body 6 and the depth of parallelism of triangle datum level 5 are 0.02;

E, CNC process: adopt the triangle needle tray 61 on CNC processing triangle needle tray body 6, the width tolerance of triangle needle tray 61 is in 0.02-0.03mm;

F, vacuum hardening: the triangle after processing is carried out vacuum hardening, and quenching hardness controls at 63 ± 1 °;

G, grinding and cleaning: the triangle after vacuum hardening is placed in lapping machine, adds oil-removing cleaning agent, grinding 4h, carries out surface removal oxide and oily waste treatment; Then clean with clear water, then be placed in half precision polisher, add brightener, take out after grinding 2h, clean with clear water.

The invention has the advantages that: processing technology is simple, and machining accuracy is high.
