Problems solved by technology

Due to the many uncertain factors of manual visual control, the quality of the formed rings is different, forcing the hot-rolled ring process to adopt the countermeasures of large tolerance and large allowance, resulting in the disadvantages of low precision of forgings and large consumption of raw materials

Abstract

The invention provides a numerical control vertical hot ring rolling mill and a control method. The numerical control vertical hot ring rolling mill comprises a rack, a roller mechanism, a measuring roll mechanism, a guide roll mechanism, a core roll mechanism, a feed mechanism and a control device. A ball screw is driven by a servo motor to drive a rolling wheel to move. The measuring roll mechanism is a follow-up measuring roll mechanism provided with a displacement sensor. The position can be adjusted through a lead screw to adapt to measuring of ring pieces of different dimensions and specifications in the rolling process. Parameters are input into a PLC, and numerical control of the vertical hot ring rolling process is achieved. By means of the numerical control vertical hot ring rolling mill and the control method, manpower can be saved, materials can be saved, the part forming accuracy can be improved, and the subsequent machine machining amount and the rejection rate can be reduced.

Description

technical field [0001] The invention belongs to the technical field of vertical hot-rolling ring machines, and in particular relates to a numerically controlled vertical hot-rolling ring machine and a control method. Background technique [0002] The vertical hot rolling ring machine is a common equipment for rolling and forming small and medium-sized rings below Φ1000mm, which belongs to radial rolling. my country is a big country in the manufacture and use of ring parts. There are thousands of hot-rolled ring machines. However, the degree of mechanization and automation of hot-rolled ring production is relatively low. Compared with the international advanced level, the overall level of online measurement and process control of hot-rolled rings is significantly different from the international advanced level. . In the traditional vertical hot ring rolling machine, the cylinder or oil cylinder drives the rolling wheel to move linearly through the piston rod and slider to rea...
