Problems solved by technology
When the working edge of the needle tooth and the fiber rub against each other to generate force, the fiber slides along the working edge from the tooth tip to the bottom of the needle tooth. During the sliding process, the fiber will wear the working edge of the needle tooth, and the second point on the working edge Therefore, in the actual production process, when the second point of the working side has a gap due to wear, the carding ability of the card clothing to the fiber is greatly weakened, and the fiber carding quality is deteriorated, which greatly affects the The service life of the card clothing increases the production burden of the enterprise

Abstract
The invention relates to metal card clothing with a curved working surface. The metal card clothing comprises a base part and saw teeth, wherein the front surface of each saw tooth is composed of a linear inclined surface, a convex arc-shaped surface and a concave arc-shaped surface; each convex arc-shaped surface is a transition surface of the corresponding linear inclined surface and the corresponding concave arc-shaped surface; the arc of each convex arc-shaped surface is tangent to the arc of the corresponding linear inclined surface and the arc of the corresponding concave arc-shaped surface; and each convex arc-shaped surface is located at the 1 / 3 to 1 / 2 position of the distance between the highest point of the corresponding saw tooth and the base part; nanoscale diamond-like particles are electroplated on the surface of each convex arc-shaped surface through a fixed-point composite coating; and the hardness of each convex arc-shaped surface is greater than or equal to 960 HV. According to the metal card clothing, the needle tooth working surface is composed of three sections, so that the concentration of acting force of fibers on a second point of a working edge is reduced, the hardness and strength of the second point of the working edge are improved, the fibers are more favorably transferred at the second point, and the service life of needle teeth is prolonged.
Description
technical field [0001] The invention belongs to the technical field of spinning equipment, and relates to a card clothing, in particular to a metal card clothing with a curved working surface. Background technique [0002] Metal card clothing has the ability to hold and puncture fibers well and is an important carding element in the spinning process. Metal card clothings are widely used in carding parts such as cylinders, licker-in rollers, doffers, and opening rollers. During the long-term carding process of the metal card clothing, the tip of the tooth punctures the carded fiber, and rubs against the fiber to cause wear, and the most serious wear is the second point of the working edge. During the process of combing the fibers, one side of the needle teeth will penetrate into the fiber along the direction of the needle teeth movement, and produce mutual friction with the fibers. The side (or surface) that interacts with the fibers is called the working edge. (or work sur...
