Copper Bar Hydraulic Continuous Drawing Line     

---

Copper bar hydraulic continuous drawing line is used for the continuous drawing process of coiled copper bars, and at the same time to achieve automatic straightening, automatic lubrication, automatic cleaning, automatic cutting-to-length, automatic discharging and automatic pancake coiling. It's applied to draw continuously and process copper bars and parts of profiled bars, and achieves unlimited length continuous drawing production for products, which is different from general single-cylinder semi-continuous drawing machine and mechanical continuous drawing machine.

This whole production line cans finish the above mentioned procedures automatically and just be operated by 2-3 workers to finish the coiled copper bars with length of thousands meters form extrusion press on one set of drawing machine under the situation of no transferring in plant. No matter how heavy the coiled copper bar is (weight up to 3 ton, or even indefinite length), it just produces a small section of waste copper from the head and the end.

Comparing with traditional drawing method, this new drawing method can improve the drawing yield rate of 6%～10%; the production efficiency shall improve from 11～13persons/hour/ton to 2.5～3.5 persons/hour/ton; The occupied production workshop area shall increase to 1/3 of traditional method; the quality of product (including damage and scratch on surface, side bending of product, color and luster coherence on product surface) shall improve obviously.
                           
The drawing line has obtained National Patent. Hydraulic continuous drawing technology is one kind of continuous and automatic copper processing technology, which achieving the continuous and automatic production for whole process of copper bars production on the foundation of dynamic integration of continuous up-casting technology and continuous extrusion technology. This kind of technology shall improve production efficiency, yield rate, product quality, work environment and product management; increase energy consumption and production occupied area; achieve the good enterprise economy benefit and society benefit. The equipment has stable movement and reliable performance, definitely achieving modern full-automatic operation, saving the cost and labor, and improving the productivity greatly.

      ■ FUCTION AND FEATURES

• Continuous drawing without pause with high efficiency

• It’s particularly suitable to pull the tenuous products with high resistance of deformation and moderate drawing speed

• unlimited for product length；no need drawing in section after cutting for tenuous products; decreasing end making ,  improving yield rate obviously

• Reducing the workers and labor cost; improving labor productivity

• Reliable equipment running and less workload for maintenance;

• Accurate mold centering and convenient and reliable mould adjustment prevent and avoid bending of products;

• On-line cut-to-length and on-line rewinding can be achieved; high degree of automation; arbitrary figure settings for length of cutting and rewinding;

• Equipped with various sensors that can record and display data such as tensile strength, stretching speed, stretching length and so on.

• Process parameter settings and input is convenient and flexible with friendly man-machine interface;

• The short process for production line and compact structure obviously reduce the occupied area and project investment cost.
