In the field of industrial production, ring rolling machines are crucial for the processing of ring forgings. When an enterprise plans to purchase a ring rolling machine, it often needs to provide a series of data to the ring rolling machine equipment supplier. These data are very important because the ring rolling machine is a customized equipment with many product models. The rolling range of each model is fixed. We need to know the values of the user's ring forgings in order to recommend a ring rolling machine suitable for his product model. The ring forging values provided by the user not only affect the selection of the equipment, but also affect the smooth progress of subsequent production.
Next, we will discuss in depth the specific data content of the rings that the company needs to provide, including the key parameters of the inner diameter, outer diameter, height, weight and material characteristics of the ring forgings, and clarify the importance of these data for the reasonable selection of the ring rolling machine model.
1-Inner diameter and outer diameter: These two data directly determine the specifications of the key components of the ring rolling machine. If the roller size of the ring rolling machine does not match the inner and outer diameters of the ring forging, the forging cannot be effectively rolled. For example, when the outer diameter of the ring forging exceeds the maximum adjustable range of the ring rolling machine roller, it cannot be placed in the equipment for processing; and if the inner diameter is too small, the existing core roller cannot be adapted, and the rolling work cannot be carried out. Only based on accurate inner and outer diameter data can a ring rolling machine with suitable roller and core roller sizes be selected to ensure smooth processing.
2- Height: The height of the ring forging has a great influence on the guide device and rolling force adjustment of the ring rolling machine. When rolling ring forgings of different heights, different rolling forces and guide methods are required. If the height is too high, the existing guide device may not be able to stably support the forging, resulting in forging deviation during rolling, affecting product accuracy and even causing scrap; the height data also determines the size of the rolling force. If the rolling force is insufficient, the ring forging cannot achieve the expected dimensional accuracy and internal quality requirements; if the rolling force is too large, it may cause defects such as cracks in the forging.
3- Weight: The weight of ring forgings is related to the power system and production efficiency of the ring rolling machine. For heavier ring forgings, the ring rolling machine needs to have stronger power to drive the rolling process. If the power system is not powerful enough, the equipment will be stuck or even unable to operate during rolling, which will reduce production efficiency and may damage the equipment. Through weight data, the ring rolling machine with matching power can be reasonably selected, and the production plan can be reasonably arranged according to the weight, such as estimating the rolling cycle and planning the equipment maintenance time.
4-Material: Material is the key factor that determines the processing technology of ring forgings. The hardness, toughness, ductility and other characteristics of ring forgings made of different materials vary greatly. Ring forgings made of aluminum alloys have lower hardness than steel, require less rolling force, and can be rolled at a relatively fast speed; while some high-strength alloy steels have high hardness and high deformation resistance, require greater rolling force and slower rolling speed, and may require special rolling processes and mold materials. Only by clarifying the material can we determine the appropriate rolling process parameters, select matching molds, and ensure the quality of forgings.
The above are the parameters and reasons of ring forgings that users need to provide when purchasing ring rolling machines.
