Device for automatically controlling tube weight of centrifugal casting machine

Abstract

The invention relates to a device for automatically controlling the tube weight of a centrifugal casting machine. The automatic device comprises an industrial touch screen, an electric cabinet, a weighing controller, a weighing sensor, an absolute value increment type rotary encoder and a turning ladle hydraulic pressure regulating valve, wherein the industrial contact screen is arranged on an operation desk; the industrial contact screen is connected with a PLC (programmable logic controller) in the electric cabinet by virtue of an industrial Ethernet, so that the functions of setting the target tube weight, setting turning ladle experience data, displaying the actual tube weight and correcting regulation parameters are achieved; the PLC is arranged inside the electric cabinet and is used for receiving the target weight data, the adjusting correction parameter and the turning ladle experience setting data coming from inputting; the analog quantity output port of the PLC controls the casting turning ladle hydraulic pressure regulating valve; the weighing controller and the weighing sensor are arranged on the centrifugal casting machine and are used for detecting the tube weight after finishing casting; the absolute value increment type rotary encoder is arranged below a casting fan-shaped ladle and used for detecting the turning angle of the fan-shaped ladle; and the turning ladle hydraulic pressure regulating valve is arranged at the hydraulic pressure valve stand of the centrifugal casting machine, connected with the turning ladle hydraulic pressure mechanism of the fan-shaped ladle and used for controlling the turning of the fan-shaped ladle. By utilizing the automatic device for controlling the tube weight of the centrifugal casting machine, the automatic adjustment of the casting pipe weight can be achieved according to a process demand.

Description

technical field [0001] The invention relates to an automatic control device for the tube weight of a centrifugal casting machine, which realizes the real-time adjustment of the tube weight of the centrifugal casting casting tube. Background technique [0002] During the centrifuge casting process, the tube weight control of the cast tube is one of the important indicators of the control level of the centrifuge. The gap between the actual tube weight and the target value is directly related to the quality and production cost of the cast tube. The actual tube weight is greater than The target tube weight will lead to high production costs, and the actual tube weight is less than the target tube weight. Products may be unqualified. Therefore, in centrifugal casting, tube weight control is an important technology. At present, in centrifugal casting, the control of the tube weight is realized by the on-site operator manually adjusting the ladle turning speed according to actual e...
