Working Principle of Tungsten Carbide Sleeve

Tungsten carbide sleeve is mainly used for stamping and drawing, it is a part to protect the equipment, and the product will be different according to different requirements. The use of tungsten carbide sleeve can effectively reduce the wear between punch or bearing and equipment, and achieve the guiding effect. In stamping dies, tungsten carbide sleeve has wear resistance, good finish and does not need to be replaced frequently, thus achieving improved utilization of equipment and personnel, and is widely used; in drawing, mainly for some copper and stainless steel parts, due to the high frequency of use, it is easy to heat up, wear the sleeve, make the punch run out, the product size error is large, and the product appearance is bad. It is suggested that customers try to choose tungsten carbide sleeve to avoid the above defects. Deli Carbide can provide high quality tungsten carbide sleeve with mirror surface finish for both inner hole and outer circle, high dimensional accuracy and good perpendicularity, which enjoys high evaluation among customers.

The working principle of tungsten carbide sleeve is as follows:

1. Tungsten carbide bushings use its contact surface to wear the bushings, protect its contact surface, and replace it after it wears to a certain degree. Tungsten carbide bushings utilize wear-resistant materials whose contact surfaces are frictional. The bushings are a common soft material that has a certain amount of avoidance and wear when rubbing, and the bushings utilize materials that reduce wear and tear of the shaft and hole, and it is a sliding bearing. Tungsten carbide bushings can be replaced many times to extend the life of the body.

2. Tungsten carbide sleeve is widely used and flexible. Generally speaking, tungsten carbide sleeve is a kind of part to protect the equipment. The role it plays in practice has a lot to do with its application environment and usage. In valve applications, tungsten carbide sleeve fits with the valve stem in the valve cover to reduce the leakage and sealing of the valve; in bearing applications, the use of tungsten carbide sleeve can reduce the wear between the bearing and the shaft seat and avoid the increase of the clearance between the shaft and the hole.

3. The production and processing strength of tungsten carbide sleeve is high, can withstand long time load, has high chemical stability, no odor to alkali, alcohol, ether, hydrocarbon, acid, oil, detergent, water (sea water), has the characteristics of non-toxic, tasteless, no rust, its widely used in alkali corrosion, environmental health, food, textile, etc., provides excellent conditions for the use of mechanical parts.
