The characteristics of each part in the structural device of the wire drawing machine

The direct twistless wire drawing machine and the twistless roving wire drawing machine are respectively composed of a winding head, a wire laying device, a wire laying off device, a barrel changing device, an oil mist lubrication device, a pneumatic device, a spray device, and a head brake device. The joint between the spindle of the machine head and the machine head body adopts a conical meshing positioning to maintain the rotation accuracy of the machine head.
The head structure is a centrifugal expansion block type, consisting of the head body, expansion block, expansion block key, pressure spring, head front cover, and head back cover. The entire machine head is made of aluminum alloy and stainless steel materials. When the machine head rotates at high speed, the expanding block supports the winding drum under the action of centrifugal force, and the fibers are wrapped around the surface of the winding drum. When the winding is completed and the machine head stops rotating, the centrifugal force disappears and the expanding block falls freely to unload the cylinder.
The motion of the spiral steel wire cable shaft of the wire drawing machine is divided into rotational motion and reciprocating motion: the rotational motion is achieved by the cable motor through synchronous belt transmission, and the reciprocating motion is achieved by the servo motor through synchronous belt, rolling screw component, and linear bearing transmission. The reciprocating stroke is between 50-200mm, and changing the position of the two limit sensors can adjust the reciprocating stroke.
The function of the derailment device of the untwisted roving drawing machine is twofold: firstly, to move the derailleur towards the machine head at the beginning of winding; secondly, to gradually move the derailleur to the right during the winding process with the extension of time and the increase of the thickness of the silk cake, so that the distance between the wire and the surface layer of the silk cake remains constant, and the tension between the inner and outer layers of the silk cake is consistent.
The drum-changing device of the wire drawing machine is jointly driven by a drum-changing motor and a cylinder to rotate to the appropriate winding position. The motor drives the rotating frame rotor through the reduction gear and chain until the position detection sensor of the machine head detects the stop; Then the positioning cylinder of the rotating frame is activated, causing the rotor of the rotating frame to rotate to the designated position and firmly clamp the stop block to ensure the normal progress of the wire drawing operation.
The pneumatic device of the direct untwisted drawing machine and untwisted roving drawing machine consists of an air pressure switch, an air pressure regulating valve, an electromagnetic valve, an actuator cylinder, and pneumatic fittings. Electromagnetic energy consumption braking is non-contact and frictionless braking. High braking torque and reliable operation. It inputs the DC power after voltage reduction and rectification into the stator winding of the motor, thereby generating electromagnetic torque opposite to the rotation direction to achieve electromagnetic energy consumption braking.
The spray device in the wire drawing machine includes the wire-laying spray and the head-changing spray. The wire-laying spray is to atomize the deionized water into droplets with a diameter of 5-10 μ m, and then spray along the approximate tangent direction of the nozzle. The function of the spray device is to clean the flat wire and prevent the conjunctiva of the wetting agent at the flat wire. The head-changing spray is used to prevent the wool from falling on the winding drum when changing the drum.
