The direct untwisted wire drawing machine and the roving roving wire drawing machine are respectively composed of a winding head, a wire arranging device, a wire arranging off-line device, a can changing device, an oil mist lubrication device, a pneumatic device, a spray device, and a head braking device.
The joint part of the main shaft of the machine head and the body of the machine head adopt the meshing positioning of the cone surface to maintain the rotation accuracy of the machine head.
The structure of the machine head is a centrifugal expansion block type, which is composed of the main body of the machine head, the expansion block, the expansion key, the pressure spring, the front cover of the machine head, and the rear cover of the machine head. The material of the whole machine head is made of aluminum alloy and stainless steel.
When the machine head rotates at high speed, under the action of centrifugal force, the expansion block supports the winding drum, and the fiber is wound on the surface of the winding drum.
When the winding ends and the machine head stops rotating, the centrifugal force disappears and the swelling block falls freely to unload the barrel.
The movement of the wire drawing machine spiral wire shaft is divided into rotary motion and reciprocating motion: the rotary motion is realized by the wire motor through the synchronous belt transmission, and the reciprocating motion is realized by the servo motor through the synchronous belt, rolling screw assembly and linear bearing transmission.
The stroke of reciprocating movement is between 50mm and 200mm, and the stroke of reciprocating movement can be adjusted by changing the positions of the two limit sensors.
The function of the off-line device of the roving wire drawing machine is to make the wire guide move towards the machine head at the beginning of winding, and the second is to make the winding process increase with the extension of time and the increase of the thickness of the silk cake.
The wire arranging device gradually moves to the right, so that the distance between the wire arranging steel wire and the surface layer of the wire cake remains unchanged, so as to ensure that the tension of the inner and outer layers of the wire cake is consistent.
The can-changing device of the wire drawing machine is jointly driven by the can-changing motor and the cylinder so that it can be turned to a proper coiling position. The motor drives the turret rotor through the reduction gear and the chain until the head position detection sensor detects the stopper; then the turret positioning cylinder moves to make the turret rotor turn to the specified position and firmly clamp the stopper.
In order to ensure the normal progress of the drawing operation.
The pneumatic device of the direct twistless wire drawing machine and twistless roving drawing machine is composed of an air pressure switch, air pressure regulating valve, solenoid valve, executive cylinder, and pneumatic pipe fittings.
Electromagnetic energy consumption braking is non-contact and friction-free braking. Large braking torque and reliable operation.
It inputs the DC power after radial step-down rectification to the stator winding of the motor, so as to generate electromagnetic torque opposite to the direction of rotation, so as to realize electromagnetic energy consumption braking.
The spraying device in the steel wire drawing machine includes a line spray and a head-changing spray. The line spray atomizes deionized water into droplets with a diameter of 5-10 μm, and then sprays them along the nozzle in a direction approximately tangential.
The function of the spray device is to clean the cable wires and prevent the wetting agent from forming a film on the wires. The head change spray is to prevent the wool from falling on the wound silk tube when the tube is changed.
