A device for grinding and removing scale on the surface of a plate

Abstract

The invention discloses a polishing and removing device for surface oxidation scales of plates. The device comprises a polishing table, and slideways are horizontally and symmetrically arranged on the side walls of the left and right ends of the polishing table; the plates can be tightly fixed to the polishing table through the cooperative arrangement of a clamping device; the position, relative to the two sides of the polishing table, of the clamping device can be adjusted through the cooperative arrangement of the slideways and clamping siding blocks; a homocentric-square-shaped frame can move on the polishing table through the cooperative arrangement of a driving motor, a threaded shaft and a fixing shaft; the movement stability of the homocentric-square-shaped frame can be improved through the cooperative arrangement of the slideways and polishing siding blocks; an air cylinder is arranged to control a polishing plate to get close to or away form the surfaces of the plates; clamping blocks and clamping grooves can get close to the plates to fix the plates or get away from the plates to unload the plates through the cooperative arrangement of fixing blocks and threaded rods. According to the polishing and removing device for the surface oxidation scales of the plates, a controller controls the device to run, the labor intensity is reduced, and the polishing efficiency is improved; meanwhile, the structure is simple, and the equipment investment and the cost are low.

Description

technical field [0001] The invention relates to the technical field of oxide scale removal, in particular to a device for grinding and removing oxide scale on the surface of a plate. Background technique [0002] In the rolling production line of the plate, the plate will be oxidized when it encounters water, and a layer of oxide scale will be formed on the surface, and the oxide scale invades the surface of the plate as a product, forming oxide scale defect residues. Scale defects significantly damage the surface properties of the plate, and therefore have a significant impact on product quality. At present, the oxide skin on the surface of the plate is generally removed by grinding with a hand-held grinder or by shot blasting equipment. Grinding and removing with a hand-held grinder is labor-intensive and low in labor efficiency. The use of shot blasting equipment to remove the investment is large and the cost is high. There is also the use of chemical pickling to remov...

AI Technical Summary

Problems solved by technology

Grinding and removing with hand-held grinder is labor-intensive and low-efficiency

The use of shot peening equipment to eliminate large investment and high cost

There are also chemical pickling methods to remove the scale on the surface of the board, but the environmental pollution is large, and it is difficult to ensure the surface quality of the board
