Description

technical field [0001] The invention relates to a control system for the production process of mechanical equipment, in particular to an intelligent control system for the production process of construction machinery shot peening cleaning machines Background technique [0002] The shot blasting machine is a mechanical equipment that uses the high-speed rotating impeller to throw the shot and sand, and hits the surface of the part at high speed to meet the requirements of surface treatment. The shot blasting machine can be divided into several different shot blasting machines according to the different process and quality requirements. , and the working mode and shot blasting time are also different. Generally, the motors and valves to be controlled are: dust removal motor, lifting motor, rotation motor, several shot blasting motors, screw motors, rapping motors and several shot blasting valves. In addition, a shot blasting machine needs to be equipped with a dust collector....

AI Technical Summary

Problems solved by technology

The existing problems are: poor reliability, high failure rate; high energy consumption; poor working environment, serious environmental pollution; relatively poor quality and skills of operators, there are potential safety hazards; low level of equipment control, low level of automation; vulnerable spare parts But pass

[0008] (1) The automation degree of the equipment workshop is not high. In the shot blasting process, many of them are manually operated, and the control of the trolley in the hook is manually operated.

Although the shot blasting machine is intelligently controlled, the degree of intelligence is not high, and intelligent control has not been realized in the identification of workpieces and the conversion of shot heads.

[0009] (2) The dust removal in the shot blasting machine studio has not achieved energy-saving optimization control

In the processing of different types of workpieces, waiting for the installation project to be idle, or the change of the differential pressure between the inlet and outlet of the dust removal gas, the optimal processing change is not realized, and the motor is basically run at one speed, which wastes a lot of energy.

[0010] (3) The process of cleaning the workshop is cumbersome and needs to be cleaned manually, and sometimes workpieces are piled up

The dust removal in the cleaning workshop also failed to achieve energy saving and optimal control, resulting in serious power loss

[0011] (4) The production process has not been networked, and the working status of each unit cannot meet the requirements of unified management after the front call, and the production efficiency is very low; similarly, the warehouse management system (WMS) in the workshop has not been implemented, which not only wastes energy and reduce work efficiency

[0012] (5) The degree of intelligent control of the motor of the shot blasting machine is not high, and most of them have not realized the intelligent speed control, which wastes energy and reduces the service life of the motor. Therefore, it is necessary to strengthen the network management of the frequency converter
