Abstract
The invention is a technics pressing wheel covets with sheet material instead of hot rolling steel. Its features lay on that: first process the sheets into strip material and tempering at 580 to 620 deg. C; and then with oid press over 500 T, obtain the product through rolling, covering, head cutting, close dot welding, welding, pre-compressing, expanding, welding gap abrading, compressing, punching the air valve hole and assembling shaping. Pressing wheel covets with this technics will save hot rolling steel while the sheet material price is 40 percent lower than it of hot rolling steel, and so to lower the cost by 5 to 11 percent. Its production efficiency is the same as section steel production line with products of reliable quality, moreover it is of low investment without any large facilities and just a set of wheel covet moulds and an oil press is needed.
Description
Technical field:
The invention belongs to agricultural machinery car tyre rim manufacturing process, especially wheel rim pressing technique using sheet material instead of hot-rolled steel section.
Background technology:
At present, the wheel rim of most of agricultural machinery car steel rings is round as a ball the making of shaped steel that form with steel mill's hot rolling, but the producer of rolling this kind section bar is few, the situation that supply falls short of demand occurs, therefore cost an arm and a leg, and gage distortion, productivity ratio is low.
Summary of the invention:
Technical problem to be solved by this invention provides and a kind ofly reduces cost, economical with materials, agricultural machinery car tyre rim manufacturing process that product quality is high.
Technical scheme of the present invention is: following billot-and at 580 ℃ of-620 ℃ of following flame enrichments-with the above hydraulic press die mould of 500T-volume circle-cover circle-crop-to holding together spot welding-welding-precommpression-expansion-mill weld seam-compression-valve hole.
Technology compacting tyre rim of the present invention can be saved hot-rolled steel section, because of the sheet material price is lower than 40% of shaped steel valency, the 5-11% so the wheel rim of the present invention's compacting can reduce cost, its production efficiency is identical with shaped steel wheel rim production line, reliable product quality, in addition, this technology investment is few, need not increase any main equipment, only need to increase a cover wheel rim press-moulding die and hydraulic press and get final product.
The specific embodiment:
Embodiment 1
Compacting 15-5.50F type car tyre rim
At first, press billot under the size of 15-5.50F type wheel rim, tempering under 585+2 ℃ temperature, then use the hydraulic press die mould of 500T, identical with the technology of producing wheel rim with shaped steel then, roll up circle, cover circle, crop, after holding together spot welding, welding, precommpression, expansion, mill weld seam, compression, valve hole and assembling shaping, obtain finished product.
Embodiment 2
Compacting 5.00S type car tyre rim
At first, press billot under the size of 5.00S type wheel rim, tempering under 615+2 ℃ temperature, then use the hydraulic press die mould of 600T, identical with the technology of producing wheel rim with shaped steel then, roll up circle, cover circle, crop, after holding together spot welding, welding, precommpression, expansion, mill weld seam, compression, valve hole and assembling shaping, obtain finished product.
Claims (1)
1, a kind of wheel rim pressing technique using sheet material instead of hot-rolled steel section, it is characterized in that: at first, sheet material is processed into billot, 580 ℃ of-620 ℃ of following tempering, then with the above hydraulic press die mould of 500T, through rolling up circle, cover circle, crop, after holding together spot welding, welding, precommpression, expansion, mill weld seam, compression, valve hole and assembling shaping, obtaining finished product.
