Device for rapidly decreasing temperature in composite steel pipe grinding process

Abstract

The invention discloses a device for rapidly decreasing temperature in a composite steel pipe grinding process. The device comprises a base, a clamping device and a grinding device. The clamping device is arranged at the upper end of one side of the base, the grinding device is installed at the upper end of the other side of the base, one end of a guide pipe is connected with a nozzle through a thread, an infusion pump is connected with a vertical baffle through the guide pipe, the upper end of an inner cavity of a liquid storage tank is provided with a filter net, a filter is connected with the infusion pump through the guide pipe, the side wall on one side of the inner cavity of the liquid storage tank is provided with a water level sensor, and the right end of the grinding device is provided with a controller. According to the device for rapidly decreasing temperature in the composite steel pipe grinding process, the flow-out amount of cooling liquid can be controlled by adding an electromagnetic valve, the temperature of the grinding device can be monitored in real time under the effect of a temperature detector, large iron scraps can be filtered out under the effect of the filter net, and fine iron scraps in cooling liquid can be further filtered out under the assistance of the filter.

Description

technical field [0001] The invention relates to the technical field of composite steel pipe manufacturing, in particular to a temperature rapid cooling device during the grinding process of composite steel pipes. Background technique [0002] At present, in order to make the welding joint of the composite steel pipe better, the iron oxide, dirt and slag at the steel pipe mouth must be removed until the metallic luster is exposed before welding can be performed, otherwise there will be impenetrable welding and welding The problem of low intensity. At present, the nozzles of some steel pipes on the market have been cut and shaped when they leave the factory, but the cutting accuracy cannot meet the technical requirements, so further grinding is required by a grinding machine. During the grinding process, the temperature of the grinding device is often too high. Slow down the rotation speed of the grinding device. Although some grinding machines are equipped with cooling devic...

[0002] At present, in order to make the welding joint of the composite steel pipe better, the iron oxide, dirt and slag at the steel pipe mouth must be removed until the metallic luster is exposed before welding can be performed, otherwise there will be impenetrable welding and welding The problem of low strength

At present, the nozzles of some steel pipes on the market have been cut and shaped when they leave the factory, but the cutting accuracy cannot meet the technical requirements, so further grinding is required by a grinding machine. During the grinding process, the temperature of the grinding device is often too high. Slow down the rotation speed of the grinding device. Although some grinding machines are equipped with cooling devices, they cannot effectively use the cooling liquid, resulting in a certain waste of resources.
