The introduction of the coil winder

（coil winder)The plastic forming method of applying tensile force to the metal blank to make it pass through the die hole to obtain the product with the same size and shape as the die hole is called drawing. Drawing is one of the main production methods of pipe, bar, profile and wire rod. The tools and equipment for drawing production are simple and easy to maintain. Products of multiple varieties and specifications can be produced on one equipment, and the size of products is accurate and the surface is smooth. Generally, drawing equipment can be divided into tube bar profile drawing machine and drawing machine.

Coil winder is the equipment for drawing metal materials. The diameter of metal material is changed by drawing to meet the required diameter requirements. Bars and tubes with different specifications and diameters can be drawn through various drawing methods such as empty drawing, swimming head drawing and changing the die. The mechanical part is composed of unwinder, pre straightener, combined puller, horizontal straightener, vertical straightener, hydraulic shear, conveyor, special-shaped blanking table, polishing straightener, turnover device, automatic chamfering machine, etc.
