Problems solved by technology

[0002] At present, most of the rims of agricultural locomotive steel rims are made of hot-rolled section steel in steel mills, but there are few manufacturers who roll this type of section, and the supply exceeds demand, so the price is expensive, and the thickness is uneven and the productivity is low.

Embodiment 1

[0007] Pressed 15-5.50F car steel rim

[0008] Firstly, cut the strips according to the size of 15-5.50F rims, temper them at a temperature of 585+2°C, then press them with a 500T hydraulic press, and then roll them up and cover them in the same way as the rims produced with section steel. , cutting head, butt welding, welding, pre-compression, expansion, welding seam grinding, compression, punching the door hole and assembly shaping to get the finished product.

Embodiment 2

[0010] Pressed 5.00S type car steel rim

[0011] Firstly, the strips are cut according to the size of the 5.00S type rim, tempered at a temperature of 615+2°C, and then pressed with a 600T hydraulic press, and then rolled, rounded, and cut in the same process as the rim produced with section steel. The finished product is obtained after head, butt welding, welding, pre-compression, expansion, grinding of weld seam, compression, flushing of the door hole and assembly and shaping.

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: [0001] The invention belongs to the manufacturing process of steel rings and rims of agricultural locomotives, in particular to the process of pressing the rims with plates instead of hot-rolled section steel. Background technique: [0002] At present, most of the rims of agricultural locomotive steel rims are made of hot-rolled section steel in steel mills, but there are few manufacturers who roll this type of section, and the supply exceeds demand, so the price is expensive, and the thickness is uneven and the productivity is low. . Invention content: [0003] The technical problem to be solved by the present invention is to provide a manufacturing process of steel rims of agricultural locomotives which can reduce costs, save materials and have high product quality. [0004] The technical scheme of the present invention is: the next strip material—adding fire at 580°C-620°C—pressing with a hydraulic press above 500T—rolling round—covering round—cutting ...
