Embodiment 1

[0035] Embodiment 1 is an elastic emery cloth with a convex circular arc, which is produced by the following process:

[0036] 1 Select elastic modified plastic as the raw material of elastic layer 3; diamond or cubic boron nitride and brittle resin are used as abrasive grains 1, and the bottom of the abrasive grains is placed into the base cloth 2;

[0037] 2. Abrasive cloth making: the base cloth with abrasive grains 1 is formed into a ring by rubber-plastic molding method and elastic layer 3

[0038] The emery cloth can also be evenly bonded on the elastic layer 3 by applying glue to form an annular emery cloth.

[0039] Such as figure 2 , image 3 , Figure 4 , Figure 5 As shown, the shape of the convex circular arc annular elastic gauze 4 is the same as the shape of the outer edge of the support base 5, its size is slightly smaller than the size of the outer edge of the support base 5, and a raised ring is arranged at the two ends of the elastic layer 3 31 is respe...

Embodiment 2

[0041] Embodiment 2, is the emery wheel of roller shape, and its processing process is as follows:

[0042] Material selection: silica gel is used as the elastic layer 2, cotton cloth is used as the base cloth 2, and silicon carbide particles are used as the abrasive grain 1;

[0043] 2. Abrasive cloth making: evenly bond the abrasive grains 1 to the base cloth 2, and cut them into emery cloth strips with the same width as required;

[0044] 3. Forming: put the cut emery cloth strip into the mold, inject silica gel to form the elastic layer 3, make the emery cloth strip with abrasive grains 1 and silica gel integrally formed, and form the elastic emery cloth 7 in the shape of a roller;

[0045] 4. Set: Set the roller-shaped elastic emery cloth 7 on the supporting base 8 to form a roller-shaped elastic grinding wheel.

[0046] Such as Figure 6 , 7 As shown in and 8 , a protruding ring 31 is provided at both ends of the elastic layer 3 of the roller-shaped emery cloth 7 , an...

Embodiment 3

[0047] Example 3, such as Figure 9 with 10 shown. It is a drum-shaped elastic emery cloth, and the elastic emery cloth 9 is set on the supporting base 10 . Can be used to grind and polish various surfaces.

Abstract

The invention discloses an elastic abrasive cloth and an elastic grinding wheel. The external layer of the elastic layer is provided with a grinding material layer; grinding grains are arranged intermittently. The elastic grinding wheel comprises a supporting base and elastic abrasive cloth; the elastic abrasive cloth comprises the elastic layer and the grinding grains; the external surface of the elastic layer is provided with a grinding grain layer with the grinding grains arranged intermittently; the supporting base is designed into various shapes according to requirements; the external profile is parallel to the shape of the elastic abrasive cloth; the elastic abrasive cloth is directly sheathed on the external surface of the supporting base to form the elastic grinding wheel. The invention has simple structure, convenient manufacture and low cost, can be made into the elastic abrasive cloth with various shapes, and can grind and polish workpieces with different dimensions and different shapes. The invention can form the elastic grinding wheel when being connected with the supporting base of a sander; furthermore, the invention can be repeatedly applied, with high jointing precision. When the grinding grains are completely consumed, the new abrasive cloth can be used for directly replacing the old abrasive cloth, with simple, convenient and fast operation.

Description

technical field [0001] The invention relates to an abrasive cloth and a grinding wheel, in particular to a grinding machine or a polishing machine which can be used in different structures. The elastic abrasive cloth and the reusable grinding wheel can be replaced. Background technique [0002] Existing emery cloths, including emery cloths made of superhard materials mainly made of diamond and cubic boron nitride, and ordinary abrasive cloths made of silicon carbide and corundum, are inelastic and mainly planar. This greatly limits the application field of abrasive cloth. When encountering the grinding and polishing of linear curved surfaces or grinding at corners, more complicated emery cloths parallel to the curved surfaces and the support matrix behind the emery cloths are required. Therefore, someone designs wheels of various shapes, and emery cloth is bonded on the wheels. These shapes can make the used grinder reach the grinding and polishing of linear curved surface...
