A casting surface sticking sand treatment device

Abstract

The invention discloses a device for treating sticky sand on the surface of castings, which comprises a casing and an annular plate; Pad connection; there is a fixed plate inside the casing, the fixed plate is connected to the motor, the motor is connected to the connecting plate, the connecting plate is connected to the telescopic device, and the telescopic device is connected to the high-pressure water spray device; there is a protective shell on the inner wall of the casing. There is a DC power supply inside the protective case; the negative pole is connected to the anode connector, and the anode connector is vertically arranged. One end of the pressure elastic member is against the bottom of the DC power supply, and the other end is against the top of the anode connector. There is a through hole on the protective case, and the anode connector The cylindrical connector of the DC power supply is electrically connected to the cathode connector through the connecting wire; the cylindrical connector of the cathode connector passes through the through hole of the protective shell. The invention improves the efficiency of cleaning the sand sticking area of ​​the casting and reduces the harm to operators.

Description

technical field [0001] The invention relates to the field of casting production, in particular to a device for treating sticky sand on the surface of castings. Background technique [0002] Usually there is a layer of hard-to-remove sand on the surface of stainless steel castings, called sticky sand. Sticky sand is divided into mechanical sticky sand and chemical sticky sand. Mechanical sticky sand is a mechanical mixture of sand particles and metal adhered to part or the entire surface of the casting. Metal luster can be seen when cleaning the sticky sand layer; chemical sticky sand Sand is a low-melting compound formed by the interaction of a layer of metal oxide, sand grains and clay on part or the entire surface of the casting. It has high hardness; it not only affects the appearance, but also reduces the mechanical properties of the casting. [0003] Therefore, those skilled in the art provide a device for treating sticky sand on the surface of castings to solve the pr...
