Abstract
The invention discloses a machining process of a stator pressing ring, comprising the following steps: firstly, selecting materials: selecting steel plates the thickness H of which is calculated by the equation H=h+delta according to the requirement of the thickness h of the stator pressing ring, wherein the delta is a first machining allowance; secondly, cutting: cutting the selected steel plates into strips according to the size of the stator pressing ring after expanding and a second machining allowance; thirdly, circularly rolling: circularly rolling the cut strips in the second step into roll materials; and fourthly, welding: welding the roll materials formed by circularly rolling into a pressing ring. According to the requirement of the thickness of the stator pressing ring and the size requirement of the expanded stator pressing ring, the steel plate is used as a machining material of the stator pressing ring, cut into the strips, circularly rolled and welded into a finished product; the material is not wasted in the thickness and radial direction and the utilization rate of the material is greatly improved up to over 90 percent; and meanwhile, the machining process has high production efficiency and the machined pressing ring has stable quality.
Description
Technical field
The present invention relates to the motor stator trim ring and make the field, be particularly useful for the production of the stator pressing ring of high-voltage motor and wind-driven generator.
Background technology
The stator pressing ring of original high-voltage motor and wind-driven generator directly adopt the cutting of integral plate flame to form (as shown in Figure 1), but stock utilization is low, angle material 2 and intermediate materials 1 around having removed, utilance is less than 35%, and the production cost height is not suitable for producing in batches.Also improve, change trim ring into forging 3, adopt Three kinds of hors d'oeuvres structure (as shown in Figure 2) thereafter, though stock utilization than previous height, forges part and belongs to roughing, 3 piece together mutually after, the inside and outside footpath of trim ring is bigger with the allowance of thickness, and production efficiency is not high.
Summary of the invention
Technical problem to be solved by this invention is at above-mentioned the deficiencies in the prior art, and the process for machining and manufacturing of the high motor stator trim ring of a kind of stock utilization is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of processing technology of stator pressing ring may further comprise the steps:
The first step, select materials: according to the thickness h requirement of stator pressing ring, choose the steel plate that thickness is H=h+ δ, wherein δ is first allowance;
Second step, cutting: the size and second allowance according to after the stator pressing ring expansion cut into billot with the above-mentioned steel plate of choosing;
The 3rd step, volume circle: go on foot the billot of cutting by the lopping of furling plate round machine volume circle with above-mentioned second;
The 4th step, welding: with the circle that above-mentioned the 3rd step is rolled into, seam adopts gas to protect and welds.
The 5th step, Vehicle Processing: with the good trim ring of above-mentioned the 4th step welding, Vehicle Processing is to the figure paper size.
The present invention adopts the rapidoprint of steel plate as stator pressing ring, and cuts into billot according to the thickness requirement of stator pressing ring and the dimensional requirement after launching and put allowance well, after be welded into half product behind the volume circle, and after be finish-machined to the finished product trim ring.On whole cover material, all there are not unnecessary angle material and clout, stock utilization improves greatly, and stock utilization reaches more than 90%, simultaneously, adopts such processing technology, production efficiency height, the trim ring steady quality that processes.
Description of drawings
Fig. 1: trim ring directly adopts the cutting of integral plate flame.
Fig. 2: change trim ring into forging, adopt the Three kinds of hors d'oeuvres structure.
Fig. 3: steel plate is cut into billot, directly be rolled into circle.
Embodiment
Below in conjunction with specific embodiment (as be of a size of Φ 740* Φ 635*30, material is that the stator pressing ring of the high-voltage motor of Q235 is given an example), the present invention is elaborated: a kind of processing technology of stator pressing ring may further comprise the steps:
The first step, select materials: according to the specification requirement of stator pressing ring drawing, choosing thickness is that H=h+ δ=35mm, material are the steel plate of Q235, and wherein δ is the thickness allowance 5mm of trim ring;
Second step, steel plate is cut into billot: calculate development size according to stator pressing ring figure paper size, promptly billot length is 2159.85mm; And by the two-sided 6mm allowance of respectively putting of the inside and outside footpath of trim ring size, promptly Qie Ge billot width is (740-635) ÷ 2+6=58.5mm; The above-mentioned steel plate of choosing is cut into the billot of 2159.85*58.5*35;
The 3rd step, billot is rolled into circle: will be above-mentioned second go on foot the billot that cuts into 2159.85*58.5*35, be rolled into the circle of Φ 746* Φ 629*35 by furling plate round machine;
The 4th step, welding: with the circle that above-mentioned the 3rd step billot is rolled into, seam 4 adopts gas to protect and welds.
The 5th step, Vehicle Processing: the good Φ 746* Φ 629*35 trim ring Vehicle Processing of above-mentioned the 4th step welding is become Φ 740* Φ 635*30, meet the drawing dimensional requirement.
