Fine Wire Drawing Machine

Fine wire drawing machine which likes NIEHOFF high speed drawing machine is developed by LINT TOP to meet market demands. It is mainly used for copper fine wire drawing processing and copper wire online annealing. It has the advantages of precision traverse, stepless dual frequency control, lower slip rate, high production efficiency, etc.

Introduction

In order to meet the requirements for drawing copper wires with smaller specifications, our company has carefully developed and designed a high-speed drawing machine, which is suitable for drawing copper wires with smaller specifications.

The copper wire drawing machine has the characteristics of small equipment footprint, high production efficiency, and low operating noise. It not only improves the production efficiency of wire drawing, but also simplifies the production process. It is currently the leading fine wire drawing production line in China.

Equipment Features

2.1 The drawing tower wheel adopts a double-layer arrangement design with novel structure, effectively reducing equipment footprint. 

2.2 All the tower wheels, counting wheels, wire guide wheel and traversing guide wheel are sprayed with ceramic, which effectively increases the service life of the equipment.

Main Components

This equipment is mainly composed of pay-off, drawing machine, annealing machine, tension controller, take-up and electric control system.

4.1 Drawing machine

Drawing machine

The drawing tower wheel adopts a double-layer arrangement design, which is driven by a main motor through 4 belt shafts and the take-up shaft through a flat belt; the round copper wire enters the drawing host through the pay-off frame, and is drawn through the tower wheel and drawing dies. When drawing, the cooling method of wire and mold is spray type. The wire passes through the take-in wheel, the counting guide wheel, the tension rocker guide wheel, the thread guide wheel, and the cable guide wheel, and enters the take-up reel. The whole machine is designed with ergonomic principles, the structure is reasonable and reliable, and the operation is convenient.

4.2 Annealing machine

Annealing machine

The annealing adopts the contact short-circuit annealing principle, and the annealing machine uses a DC controller to track the takeup speed to control, ensuring that the wire is fully annealed when it is started and stopped. The annealing machine consists of a conductive system, an oxidation protection system, a cooling system, a drying system, and an electrical system. The oxidation protection method adopts steam protection; the cooling and lubrication adopts the drawing fluid with a concentration of 0.5% to 1%. Generally, cooling is provided by setting a pool or an external heat exchanger; the drying system uses compressed air and dies to dry. It can ensure that the appearance of the annealed copper wire is bright and free of oxidation, and can also meet the performance requirements of the elongation and resistivity of the annealed copper wire.

4.3 Take-up 

Take-up

The take-up adopts PND 400 high-speed wire take-up machine, which is suitable for the take-up of high-speed wire drawing machine. According to customer requirements, single or double reels can be selected, suitable for PND400 or PND300 reel. The clamping, lifting and braking of the reels are all pneumatic. The traversing system is driven by an independent motor and switched by a screw rod clutch. The braking system of the winding part adopts pneumatic brakes. When a disconnection occurs during operation or an emergency stop is performed, an emergency stop is performed immediately, quickly and promptly. Brake the reel to prevent damage to the wire and ensure safe operation.
