Method and device for removing rust on sheet metal

Abstract

The invention provides a method and a device for removing rust on sheet metal. The device comprises a stander, a sheet clamping mechanism arranged on the stander and used for clamping the sheet, at least one belt grinding mechanism arranged at one side of the sheet clamping mechanism, at least one pressure mechanism arranged in the sheet clamping mechanism, a first transmission mechanism connected with the belt grinding mechanism, a second transmission mechanism of the pressure mechanism, and a control mechanism connected with the first transmission mechanism and the second transmission mechanism, wherein the control mechanism is controlled by the pressure mechanism to force a sand belt of the belt grinding mechanism to movably contact the surface of the sheet to complete the removal of a metal oxide layer on the surface of the sheet. The invention not only can solve the problem that rust cannot be removed thoroughly and manually, but also can lighten the labor intensity of workers, enhance the production efficiency, reduce the replace times of grinding material and lower the production cost.

Description

technical field [0001] The invention relates to metal surface treatment, in particular to a method and device for removing rust on the surface of metal plates. Background technique [0002] The continuous production of strip steel usually includes a splicing process, and in order to meet the strength requirements of the spliced ​​strip at the joint, it is usually necessary to remove the oxide layer on the surface of the steel plate joint (weld) before welding. (rust removal) treatment. [0003] A common derusting method is to manually use a hand-held pulley machine to remove the rust, and grind the oxide layer on the surface of the steel plate to remove the rust. The grinding time is long and the efficiency is low, which does not meet the requirements of automatic production. Requirements, and incomplete grinding will result in insufficient weld strength, resulting in broken belts, which will also cause the suspension of the production line and cause great losses. Moreover...

Problems solved by technology

[0003] A common derusting method is to manually use a hand-held pulley machine to derust, and grind the oxide layer on the surface of the steel plate to remove the rust. The grinding time is long and the efficiency is low, which does not meet the requirements of automatic production. Requirements, and incomplete grinding will result in insufficient weld strength, resulting in belt breakage, which will also cause the suspension of the production line and cause great losses

Moreover, the manual derusting method requires a high labor intensity for the operator, and the rust powder and dust emitted during the derusting process not only easily cause environmental pollution, but also easily endanger the health of the operator; It needs to be replaced frequently during the process, and the replacement process is cumbersome, which also affects the grinding efficiency
