Abstract
The invention discloses an engineering wheel rim which is formed by machining a steel plate, wherein the steel plate comprises the following main components: C: 0.09-0.11, Si: 0.02-0.03, Mn: 0.50-0.55, P: 0.03-0.05, S: 0.01-0.03, Al: 0.021-0.025, V: 0.002-0.004 and Nb: 0.001-0.002. The yield strength of the steel plate is 300-350N/mm<2>, the tensile strength thereof is 400-420N/mm<2> and the elongation thereof is 31%; and the steel plate is applicable to mass industrial production. The invention further discloses a machining method of the engineering wheel rim, comprising the following steps: a. shearing the steel plate into strip materials; b. rolling the strip materials into a cylindrical shape; c. welding the cylindrical strip materials to form a closed cylinder; and d. directly pressing the strip materials to form the rim. Compared with the prior art, the invention has the beneficial effects of saving machining steps, requiring no high-temperature heating and saving energy and time.
Description
Technical field
The present invention relates to a kind of engineering truck wheel rim and job operation thereof.
Background technology
At present, common engineering truck wheel rim and process steps thereof are; Blanking, volume circle, welding, heating, die mould.There is certain defective in this method: 1, need be heated to about 600 ℃ before the moulding, expending can; 2, heating produces oxide skin, causes producing surface blemish in the die mould process.3, the cooling process wheel rim behind the die mould can produce the fitfull distortion.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides better engineering truck wheel rim of a kind of saving procedure of processing and toughness and job operation thereof.
For achieving the above object, the present invention is realized by following technical solution:
A kind of engineering truck wheel rim, described wheel rim adopts steel plate to process, described steel plate main component content is: C:0.09～0.11, Si:0.02～0.03, Mn:0.50～0.55, P:0.03～0.05, S:0.01～0.03, Al:0.021～0.025, V:0.002～0.004, Nb:0.001～0.002.
The yield strength of described steel plate is: 300～350N/mm
2, tensile strength is: 400～420N/mm
2, percentage elongation: 31%.
A kind of job operation of engineering truck wheel rim, described procedure of processing is:
A, use steel plate shearing as claimed in claim 1 become the rectangular material of 1940mmX240mmX11mm;
B, make its one-tenth cylindric rectangular material volume circle;
C, rectangular material cylindraceous is welded into the osed top cylinder;
D, direct die mould make rectangular material become wheel rim.
Compared with prior art, beneficial effect of the present invention is: save procedure of processing, need not the high temperature heating, saved the energy and time.
The specific embodiment
For the ease of understanding the present invention, the spy is further described in conjunction with the specific embodiment, but present embodiment should not regarded any limitation of the invention as.
A kind of engineering truck wheel rim, described wheel rim adopts steel plate to process, described steel plate main component content is: C:0.09～0.11, Si:0.02～0.03, Mn:0.50～0.55, P:0.03～0.05, S:0.01～0.03, Al:0.021～0.025, V:0.002～0.004, Nb:0.001～0.002.
The yield strength of described steel plate is: 300～350N/mm
2, tensile strength is: 400～420N/mm
2, percentage elongation: 31%.
A kind of job operation of engineering truck wheel rim, described procedure of processing is:
A, use steel plate shearing as claimed in claim 1 become the rectangular material of 1940mmX240mmX11mm;
B, make its one-tenth cylindric rectangular material volume circle;
C, rectangular material cylindraceous is welded into the osed top cylinder;
D, direct die mould make rectangular material become wheel rim.
With 25 cun 2.5 wheel rim is example:
1, uses the thick LG370C steel plate shearing growth billot of 11mm.
2, that workpiece is become is cylindric for volume circle.
3, welding makes workpiece become the osed top cylinder.
4, directly die mould becomes workpiece to meet the wheel rim of GB/T2883.
Advantage of the present invention is:
1, do not need heating process, reduce by 80% energy resource consumption.
2, do not have the impact of oxidation skin, die mould rear surface roughness can promote a grade than the roughness of raw material (steel plate).
3, can control better the shape of moulding, promote the fitness of wheel rim and tire.
