[ Metal wire rolling mill ]

CDOCAST metal wire rolling mill machine is mainly suitable for rolling pure silver wire, K gold wire, pure gold wire, and silver alloy wire, copper wire, copper alloy wire…etc

The metal wire rolling mill is mainly composed of machine body, wire straightening mechanism, rolling mechanism, take-up mechanism, cooling and lubrication system, transmission system and electric control part.

The body is welded with steel plate and section steel, and the pinion box is cast. The transmission part is driven by helical gear and spiral bevel gear. The roll is made of special alloy steel and processed by the heat treatment process, which has the advantages of super wear resistance and impact resistance. The rolling part is cooled and lubricated by spraying. The power adopts frequency conversion stepless speed regulation.

Multiple roll boxes are arranged in parallel on the machine body. Each roll box has two pairs of longitudinal and transverse rolls. The two pairs of rolls are distributed horizontally and vertically respectively. The line diameter after rolling is gradually reduced in proportion. The compression rate is designed according to the material extension characteristics. The compression of each pass is equal. When the wire passes through the roll, the material is pressed by the rotating roll, The reduced wire rod is extruded from the roll, and finally, the wire rod is transported to the receiving tray through the traction device to realize the rolling of the wire rod.

Special instructions for this metal wire rolling mill:

1. When producing silver wire, K-gold wire and other alloy wires, it is necessary to use another winder together with the rolling mill to prevent the wires from being scattered.

2. This metal wire rolling mill is rolled by two driving rollers without the use of molds, and there is no gap between the two rollers. Therefore, the rolled wire material cannot reach the roundness and smoothness of the wire material drawn by the wire drawing machine with a certain ovality. Therefore, the rolling mill cannot complete the final products, and the subsequent wire drawing machine is required to complete the round requirements of the wire material.

Feature

1. Strong adaptability: this automatic rolling mill can roll hard materials, which can not be achieved by a general high-speed rolling mill.

2. Low energy consumption: there is no need to use eye mold for our metal wire rolling mill. Because there is no need to draw the eye mold in the work, the energy generated by the deformation and heating of the wire rod through the mold and the friction and heating of the wire rod through the eye mold is reduced; In the working process, the wire runs in a straight line to reduce the heating caused by the bending deformation of the wire on the tower wheel; In the rolling process, the slip of wire rod is small and the useless work consumed is small.

3. Low noise: during the drawing process of the traditional water tank wire drawing machine, the wire rod and the tower pulley slip, and the noise generated by the wire rod passing through the eye die is large, while our wire rolling mill does not shake during the rolling process, and the slip through the roll is small, so the noise is low.

4. No wire drawing die is needed: the operation is simple and convenient, which saves the die threading time, reduces the labor intensity of personnel, and improves the work efficiency.

5. The quality of the produced wire rod is excellent: it is not easy to break the wire in the subsequent drawing. After the wire rod is rolled, the metal structure will be more dense and convenient for subsequent processing.

Feature

1. Master cylinder: piston cylinder (German technology) is adopted.  working pressure error (0.002kg), with the characteristics of strong and constant speed stability, the hydraulic system ensures the stability of metal flow extrusion and makes the connection firm at the interface.
2. Built-in sub cylinder: It has the function of rapid oil filling, reducing no-load time, quickly reaching the working pressure, and improving efficiency.
3. CDOCAST metal extruder adopts four guide rod structure, which makes the rigidity of the machine better and fully improves the balance of extrusion.
4. The die head of the machine adopts the front mode, and the extrusion die head is set between the front seat of the oil cylinder and the piston rod. Because the machine adopts the continuous extrusion mode, there is no need to make the extrusion discus used by other manufacturers in the extrusion process, so many intermediate processes and actions are simplified.

5.5. The die head of the machine adopts the front, and an opening and closing movable plate is added. The extrusion die head is installed on this plate, and two oil cylinders are provided to support it from both sides to prevent the movable plate from retreating. When it needs to be opened, the movable plate is pulled and slid through the two oil cylinders to facilitate the assembly and disassembly of the extrusion die.
6. The extrusion die head adopts double-layer structure and is made of special high-temperature resistant materials through special heat treatment process. It has the characteristics of high pressure resistance, high temperature resistance and high hardness, so as to prevent the risk of hardness reduction due to the increase of die head temperature. The die head of the machine is heated by electromagnetic induction heating, which is efficient and fast, which can not be realized by using resistance heating ring. However, the use of electromagnetic induction heating can realize various temperatures required by the die head process, and can better meet the requirements of various production processes.

7. The Metal Extrusion Machine has the ability of automatic mold opening and closing and mold out. It is equipped with two mold opening and closing oil cylinders, which are placed on the left and right sides of the machine. After the oil cylinder pushes open the movable plate of the movable die head, it is equipped with a mold-out oil cylinder, which is installed on the front seat. The mold-out oil cylinder pushes the mold base plate. The mold base plate is equipped with two holes, one for extruding the outlet hole and the other for mold out hole, When the die base plate is pushed to the die outlet hole, after the die base movable plate is attached, the extrusion ejector rod can push the die out of the die base, which is easy and convenient, and the die change is convenient and fast.

8. The extrusion die and extrusion rod are forged with high temperature resistant special materials and processed by a special heat treatment process. They have the characteristics of high pressure resistance, high temperature resistance and high wear resistance. Because the machine does not need to use extrusion pad in the extrusion process, it has higher requirements for the performance and accuracy of ejector rod and die, so as to ensure the stability and continuity of extrusion.

9. The front seat and rear seat of the machine are made of steel castings to ensure the strength and rigidity of the machine, and ensure that the coaxiality and perpendicularity of the ejector rod and the die head are still maintained under high pressure during extrusion.
10. The machine adopts advanced hydraulic system and is equipped with two sets of systems, which are divided into high-pressure system and low-pressure system. The main cylinder and fast cylinder adopt high-pressure system, and the mold opening, closing and ejection devices adopt low-pressure system. The high-pressure system is composed of two oil pump motors. The main pump motor is mainly used to squeeze the workpiece, and the other is an auxiliary motor for rapid oil filling and pressure starting. When the rapid oil filling is completed, it will be converted to circulating hydraulic oil for cooling through the cooler to prevent the oil temperature from rising
