The drawing machine is applicable to the drawing of copper bars, copper rod, and other materials via the mold. The well-drawn finished products can achieve the goals of higher accuracy, brighter surface, greater hardness and elasticity, and difficult deformation. Such a hydraulic drawing machine is presently the substitute of chain drawing machines because it can substantially reduce operating employees, ease labor intensity, and improve the operators' safety while having the best performance and high automatic. The length of the machined products can set out of the total length range as required.
Process flow of Hydraulic drawing machine
Copper bar head sharping → unreeling → straighten and conveying → clamping → lubricating → drawing → saw cutting →lateral movement → roll conveying → saw cutting with fixed length → roll conveying to the storage table.
Main Body of Drawing Machine: The main body (bed) of the drawing machine is equipped with guide rails, which is used for reciprocating motion of fixed drawing head in the drawing process and will not deform when it is subjected to tension.
The mainframe of Drawing Machine Copper Rod Rack: This rack for Hydraulic drawing machineis made of profiled steel through welding. On its bottom are mounted the pulleys that can reciprocate crosswise according to the width and speed of copper strips, which can ensure that the copper strips are at the central position when entering the straightener. Its load-bearing capacity is 5000kg.
Mobile Rack Straightening Feeder for drawing machine for copper bar: It is made of steel plate through welding. It is equipped with the longitudinal and transverse rollers to adjust the gap by hand wheel and straighten the blank so as to prevent the bent blank from entering the drawing die.
Copper Bar Straightener Drawing Die Holder of drawing machine for copper bar: This die holder is used for placement of die. The position of the die holder can be required to be adjusted according to the curvature of both sides of the finished product after drawing to guarantee the quality of finished products. The special oil tank and pump can be used to form the oil curtain to guarantee the lubrication of die.
Drawing Die Holder Hydraulic System: The hydraulic system of copper bar drawing machine includes Hydraulic Station and drawing oil cylinder. The Hydraulic Station employs the removable (logical) valve to guarantee the stability of use process. The oil pump consists of main pump and auxiliary pump to make drawing and resetting with different speeds so as to improve production efficiency. The hydraulic cylinder is made of overall seamless steel pipe through machining and the drawing length can be set at random.
Hydraulic Oil Cylinder of Drawing Machine Cutting Mechanism: The cutting mechanism of Hydraulic drawing machine is fixed at the rear of the die holder and uses the saw blade for cutting. It can automatically complete cutting the blank and resetting after the drawing length is set.
Cutting Mechanism Drawing Head for Hydraulic drawing machine: It is fixed at the front of the hydraulic rod. It realizes clamping and loosening according to the pneumatic principle. The fixtures can be changed to draw the flat and cylindrical blanks. Drawing Head Transfer Mechanism for copper bar hydraulic drawing machine: The mechanism is used to convey the after-cut finished products crosswise to the transfer roll table for entry into the next procedure. It can carry out pneumatic clamping, electric motion, and automatic resetting.
Transfer Mechanism Roll Table for Hydraulic drawing machine: It is used for the transport of finished products.
Transfer Roll Table Cutter for Hydraulic drawing machine: It is used for the fixed-scale cutting of finished products. It cuts the finished products with the saw blade by hydraulic locking and collects the copper scrap with the recycling bin.
