Needling roll

Needle roller is a mechanical processing tool used for embossing and concave processing of metal workpieces, which is commonly used in the metal manufacturing process of automobile, ship, aviation and other industries. The following will introduce the structure, working principle, application scope and market prospect of needling roller in detail.

The needling roller is composed of bearing, shaft, needling head, short rod and other parts. Among them, the bearing is the part of the moving bearing that provides the whole mechanical device, and the bearing force is uniform and the bearing capacity is strong; As the core part of connecting other parts, the shaft has the role of bearing the weight of the workpiece and transferring the force; The needle head is the part actually used for acupuncture, generally made of high-strength alloy material, with high hardness and wear resistance; The short rod is connected to the shaft through the bearing and plays the role of fixing the needle head.

The working principle of the needle roller is to realize the movement of the needle head by rotating the shaft. The needle head moves on the metal workpiece at a higher speed and produces scratches through the high-frequency hammering effect, thus achieving the purpose of the needle. In this process, the force applied by the acupuncture head should be uniform to ensure the uniformity and consistency of the acupuncture effect, and attention should also be paid to controlling the depth of the acupuncture head to avoid irreparable damage to the workpiece.
