Automatic cutting system for casting riser

Abstract

The invention discloses an automatic cutting system for a casting riser. The automatic cutting system comprises a cutting machine and a first motor, a second motor, a third motor, a remote control unit and an automatic control device which are connected with the cutting machine; the automatic control device comprises a receiving unit, a signal conversion unit and an automatic control module which are sequentially connected, and the automatic control module comprises a first contactor, a second contactor, a third contactor, a fourth contactor, a fifth contactor and a sixth contactor. According to the automatic cutting system for the casting riser, the function of automatically adjusting a cutting arm is achieved by arranging the remote control unit and the automatic control device, remote operation control is achieved by operating the remote control unit and adjusting the position relation between the cutting machine and the casting riser, then the purposes of reducing the labor intensity of site operation personnel and increasing the cutting rate and the coincidence rate of equipment cutting are achieved, and meanwhile personnel health and safety are guaranteed.

Description

technical field [0001] The invention relates to the technical field of cutting risers of castings, in particular to an automatic cutting system for risers of castings. Background technique [0002] In the traditional casting process, the cutting equipment used in the riser cutting process of castings is mainly Messer manual torch and oxygen blowing pipe, but the cutting length of the manual torch is limited, and it is impossible to cut large risers with a size above 600mm. The riser is mainly melted and cut with an oxygen blowing tube. However, the surface quality of the castings cut by the oxygen blowing pipe is relatively rough, resulting in a large amount of subsequent processing, and a large amount of smoke and dust is generated, resulting in a very harsh on-site environment and affecting the health of on-site employees. On the other hand, the casting needs to be preheated before cutting the riser, and the preheating temperature is as high as 600°C. When cutting with a ...

Problems solved by technology

[0005] In this method, due to the large size of the casting and the complicated mechanism, when an operator closely observes the position of the cutting machine gun body, the casting, and the riser, the heat radiation temperature of the casting, the riser, and the cutting machine is high, and the operator operates at close range. There are risks such as flame splashing, and because the on-site operators wear labor protection, communication is inconvenient, which seriously restricts cutting efficiency
