Description

Technical Field

[0002] The existing blade polishing wheel has an undevelopable drum-shaped, spherical or other curved surface structure, and has the characteristics of small geometric size and long service life, and is used for polishing complex curved surfaces of blades.

[0003] The abrasive part (abrasive shell) of the tool can only be divided into two halves during manufacturing, and there is an obvious gap after assembly, which is easy to scratch with the small radius intake and exhaust edges. During processing, the abrasive shell of the polishing wheel needs to be decomposed into two halves and installed on the elastic layer through vulcanization. Two longitudinal gaps will appear at the joint of the two halves of the shell, which has an adverse effect on the subsequent processing process.

[0004] In view of this, we propose a welded seamless metal mesh polishing wheel. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 3 As shown, the outer layer of the wheel core 101 is provided with an elastic matrix 102, and the outer layer of the elastic matrix 102 is covered with an abrasive shell 103;

[0022] The abrasive shell 103 includes a metal mesh cloth 10301, and a group coating layer 10302 is arranged on the lower layer of the metal mesh cloth 10301. The resist coating 10302 can be printed and prepared after 201D forming, and can also be printed before the metal mesh cloth 201 is cut. A thin film structure 10303 is arranged on the surface of the metal mesh cloth 10301, and a plurality of abrasive seats 10304 are arranged on the thin film structure 10303. An electroplated nickel layer 10305 is arranged on the abrasive seat 10304, and an abrasive 10306 is arranged on the electroplated nickel layer 10305.

[0023] The wheel core 101 is made of aluminum, steel or non-metallic material. A connecting hole is opened inside the wheel core 101. The connecting hole can be a cylindrical hole, a conical hole or a threaded hole, which is used to install the polishing wheel on the polishing wheel rod. The elastic base 102 is made of rubber, resin or other materials with certain elasticity.

[0024] The surface of the metal mesh cloth 10301 is electroplated to form an abrasive seat 10304, and the abrasive 10306 is fixed on the abrasive seat 10304 using an electroplated nickel layer 10305 by an electroplating method.

[0025] The preparation method of the welded seamless metal mesh polishing wheel comprises the following steps: firstly, cutting the flat metal mesh into a strip structure with a certain width; secondly, fixing the strip metal mesh with a fetal membrane so that the strip metal mesh is overlapped together and welding the overlapped parts with a resistance welding method to form a barrel structure; finally, placing the barrel structure metal mesh in a formed fetal membrane, using a rubber bag to expand it into a shape consistent with the fetal membrane under the action of a press, and then cutting it; then, using a vulcanization method, using an elastic matrix 102 to connect the wheel core 101 and the metal mesh 10301 into a whole, so that they constitute a polishing wheel matrix; finally, After cleaning the surface of the polishing wheel base, the metal mesh 10301 in the hollow structure is exposed to maintain good conductivity, and the electrode 104 is prepared on the metal mesh 10301 by welding or other methods. The electrode 104 is connected to the wheel core 101 so that it can be energized through the wheel core 101 for later electroplating. The abrasive seat 10304 is formed by electroplating in the hollow area of ​​the polishing wheel base. If a particularly precise polishing wheel is required, the abrasive seat 10304 can be further ground by a forming grinder to ensure that the outer surfaces of all abrasive seats 10304 are on the same surface to form a polishing wheel electroplating base.
