Abrasion-resistant cutting blade special for motor

Abstract

The invention discloses a special wear-resistant cutting disc for electric motors, which comprises a circular base plate, an annular cutting belt is arranged on the circumference of the base plate, a bearing hole for installing a bearing is arranged at the center of the base plate, the bearing hole is connected with the cutting There are several evenly distributed strip-shaped holes between the belts, wedge-shaped grooves are also arranged on the base plate, and several muffler holes are fixed on the outer end of the bearing hole, and the muffler holes are set on the base plate, and the base plate A wear-resistant layer is also fixedly installed on the outer surface, and the thickness of the wear-resistant layer is 1-3mm. The invention adopts an annular cutting belt, which has a simple structure and can effectively cut hard and brittle objects such as ceramics and vitrified bricks. The effective cooperation of wedge-shaped grooves and strip-shaped holes is helpful for rapid chip removal and The heat dissipation further improves the service life of the cutting disc. At the same time, the sound-absorbing holes are set on the upper surface of the base plate, which can effectively absorb the sound generated during the cutting process.

Description

technical field [0001] The invention belongs to the field of electric motor equipment, and in particular relates to a special wear-resistant cutting sheet for electric motors. Background technique [0002] Cutting discs belong to the grinding wheel, and are made of abrasives and binder resins for ordinary steel, stainless steel and non-metallic materials. Cutting discs are mainly divided into fiber resin cutting discs and diamond cutting discs according to their materials. 1. Resin cutting discs use resin as the binder, glass fiber mesh as the ribs, combined with a variety of materials, and the cutting performance is particularly remarkable for difficult-to-cut materials such as alloy steel and stainless steel. Two cutting methods, dry and wet, make the cutting accuracy more stable. At the same time, the choice of material and hardness of the cutting disc can greatly improve your cutting efficiency and save your production cost. 2. Diamond cutting disc is a cutting tool, w...

Problems solved by technology

[0003] At present, the existing cutting blades are composed of a machine body and a cutting body, and the cutting body is mostly a whole, which cannot be precisely processed for some brittle and hard objects, and it is not easy to remove chips and dissipate heat during processing, which reduces the service life of the cutting blades. increased production costs
