Problems solved by technology

[0005] (2) The reapplicability is poor, and the resources cannot be fully recycled;
[0006] (3) The cost of substrate treatment after use is high, and many units are unwilling to dispose of the used substrate and burn it, causing air pollution;
[0007] (4) The cost of manufacture and use is relatively high. At present, the market prices of plastic substrates, rigid paper substrates, and glass mesh cloth substrates are: 0.2-0.32 yuan / piece, 0.6-0.7 yuan / piece and 0.5-0.6 yuan / piece , and, due to the high consumption, users cannot afford

Embodiment 1

[0036] As shown in Figures 1, 2, and 3, the abrasive disc for processing metal workpieces is composed of a substrate 1 and an abrasive cloth sheet 2, and the abrasive cloth sheet 2 is adhered to the inner ring of the substrate 1 in a radial manner by an adhesive. On the surface, the base 1 is an integral stamped metal component stamped from a cold-rolled steel sheet. The thickness of the cold-rolled steel sheet of the metal component is 0.2mm. The center of the base 1 is stamped with a pit 4 with a mounting hole 3. Bonding The face is flat.

Embodiment 2

[0038] As shown in Figures 1, 2, and 3, the abrasive disc used for processing metal workpieces is composed of a substrate 1 and an abrasive cloth sheet 2, and the abrasive cloth sheet 2 is adhered to the inner ring surface of the substrate in a radial manner by an adhesive Above, the base 1 is an integral stamped metal component stamped from a cold-rolled steel sheet. The thickness of the cold-rolled steel sheet of the metal component is 1.5 mm. The center of the base is stamped with a pit with a mounting hole, and the bonding surface is processed into a rough surface. flat.

Embodiment 3

[0040] As shown in Figures 1, 4, and 5, the abrasive disc for processing metal workpieces is composed of a substrate 1 and an abrasive cloth sheet 2, and the abrasive cloth sheet 2 is adhered to the inner ring of the substrate 1 in a radial manner by an adhesive. On the surface, the base body is an integral stamped metal component stamped from a hot-rolled steel sheet, the thickness of the metal component sheet is 2.5 mm, and the center of the base body is stamped with a pit 4 with a mounting hole 3. A stamped groove structure for holding the adhesive is arranged. The grooves are small round grooves evenly distributed on the bonding surface, such as millet word grooves, small cross grooves, small Z grooves or small S grooves, and the grooves are arranged in a radial shape. In this embodiment, small round grooves with star cloth are used 5.

Abstract

The present invention relates to one kind of abrasive cloth disc for machining metal workpiece, and the abrasive cloth disc consists of one basal body and one abrasive cloth layer. The abrasive cloth layer is adhered by means of adhesive onto the basal body, and the basal body is one integral punched metal member of 0.2-2.0 mm thick sheet and with one central installation hole. The present invention has environment friendship, high integral strength and low cost.

Description

technical field [0001] The invention relates to a sanding plate used for processing metal workpieces. Background technique [0002] The sand discs used for processing and derusting metal workpieces are also called sand discs, butterfly discs, and small flowers at home and abroad. They are the same tool, but the names are different. It consists of three parts: 1. Matrix; 2. Emery cloth sheet; 3. Adhesive. These three parts also appear on the market in the form of independent products, and the combination of the three is a tool for processing. Due to the simple structure and low technical content of this product, with the increase of social demand, there are more and more manufacturers, all over the United States. According to statistics, the annual domestic production of this product has reached 386 million, and the annual export is nearly 80 million. Although the structure of the product is simple, due to its processing function in high-speed rotation, there is no better ...
