Research and analysis of tire pattern forging process

In the general forging industry, the tire die forging parts are mainly produced on the forging hammer, and the quality and volume are generally small. Because the mass of large forgings is larger, the forging process is more difficult to control, so the general large forgings mainly rely on free forging to form, and generally for single or small batch production. When using tire die forging to produce small batch or single piece production, special die needs to be added, the production cost will be higher than that of free forging, and large tonnage equipment needs to be selected during forging, which also brings inconvenience to the production. For large tire die forging parts with complex shapes, the process is difficult to control, so under the guidance of the lack of accurate and mature production process, Companies are reluctant to produce large tire die forgings. However, when the dimensional accuracy of forging parts is high or the allowable machining allowance is small, the tire die forging is a more ideal method.

Large roller forgings have special shape, forming flange shape is rectangular, large section, and the flange and the adjacent step section difference is large, in forging limited by equipment capacity and steel ingot type, increase the difficulty of production, and it is difficult to ensure the appearance size and internal quality requirements during forging. If the traditional free forging process production, forging precision is low, it is necessary to use large ingot forging, not only the forging penetration of the forging is poor, but also the loss of too much material, reduce the utilization rate of materials, and then cause a lot of waste, increase the production cost.

In order to ensure the above requirements, it is necessary to optimize the traditional forging process and use the tire die forging process. Although the mold is added during forging, due to the high precision of the tire die forging, small steel ingot can be used for production, with small processing allowance and high material utilization rate, thus greatly reducing the production cost. Therefore, the tire die forging of the grinding roller is an ideal forging process method. In addition, the total length of the shaft is short, which is also beneficial to the use of tire die forging.
