What are the main structural devices of high-speed wire drawing machine?
High-speed wire drawing machine can be used to draw various metal wires. As a commonly used wire drawing equipment, its main electrical transmission parts include a drafting motor, take-up motor, and wire arrangement motor.
Other auxiliary parts of the high-speed wire drawing machine equipment include a swing bar (tension frame), a positioning wheel, a dividing wheel, a reciprocating wire arrangement rod, etc.
The drafting motor of the high-speed wire drawing machine drives the drawing wheel to operate. The four-stage drawing wheel is linked through the belt to realize metal stretching, and the take-up motor realizes winding.
Structurally speaking, the high-speed wire drawing machine is mainly composed of a winding head, a wire arrangement device, a wire arrangement off-line device, a barrel changing device, an oil mist lubrication device, a pneumatic device, a spray device, and a machine head braking device.
Among them, the winding head structure is composed of the joint part of the main shaft of the machine head and the machine head body using conical meshing and positioning 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 machine head body, the expansion block, the expansion block key, the pressure spring, the machine head front cover, and the machine head back cover.
During the operation of the high-speed wire drawing machine, the machine head will rotate at high speed. Due to the influence of centrifugal force, the expansion block will support the winding drum and the fiber will be 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 swelling block falls freely and the barrel can be unloaded. to
The cable arrangement device is also one of the necessary devices for the normal operation of the wire drawing machine equipment.
Normally, the motion of the spiral steel wire arranging shaft is divided into rotational motion and reciprocating motion: the rotational motion is realized by the arranging 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 reciprocating stroke is between 50 and 200mm. The reciprocating stroke can be adjusted by changing the positions of the two limit sensors. to
At the same time, the cable arrangement separation device mainly plays two major functions:
One is that during the operation of the high-speed wire drawing machine equipment, the wire arranging device can be moved toward the direction of the machine head when the winding starts.
Second, as time prolongs and the thickness of the filament cake increases during the winding process, the cable arranger gradually moves to the right (also called lateral movement).
Keep the distance between the wiring wire and the surface layer of the wire cake constant, so that the tension of the inner and outer layers of the wire cake is consistent.
