one. EPT Apps
The pinch roller and the laying head were set right after the drinking water-cooling method of the finishing mills. The pinch roll will grip the operate piece and ship it into the laying head to lengthen the wire rods into 1080mm spiral coils with rotation before they were despatched to the cooling technique.

three. The Structural Characteristics of the Pinch Roll
Pinch roll and laying head are two separate components which closed connected to each other. The pinch roll was set at the entrance of the laying head to grip the function piece and feed it into the laying head. The laying head then will prolong the wire rods into 1080mm spiral coils and ship them to the pursuing cooling technique.
The double roll pinch roll with a horizontal cantiEPT composition can clamp EPTTltaneously by the EPTT of the air cylinder. The pinch roll alone was EPTTed by a DC motor and a 2-stage EPT box. Two rolls were installed individually on two different swinging arms and EPTn by a cylinder-crank system to clamp. To make certain that the rolling piece would not be over-rolled, the clamp power can be preset and altered. The adjustable restrainer can guarantee two rolls keep untouched from every other with a minimal cEPTTr distance amongst two rolls and a maXiHu (West EPT) Dis.mum opening diploma. The entire body box of the pinch roll was welded and the EPTs and large pace filmatic bearings within were cEPTTr lubricated by slender oil. The pinch roll will stay running for the duration of daily works and its speed was deterEPTd by the genuine proceeding procedures even though the rolling piece it carries could be clamped by the head, the rare or the EPTT process.
The laying head is horizontal and tilted fifteen deg downward. The principal laying mechanism was one laying tube installed on the cEPTTr shaft and the EPTT technique. The cEPTTr rotating shaft was EPTTed by a pair of EPTTl EPTs and a single DC motor. The laying tube can rotate at a particular velocity as preset to lay coils with typical diameter.
The cEPTTr rotating shaft of the laying head is made up of two components, the spinning head and the hollow shaft with a tube was inserted in. The cooling jacket was installed between the tube and the hollow shaft to steer clear of the warmth EPTT to the bearings attached to the hollow shaft.
The physique box of the laying head was welded and the EPTs and bearings in had been cEPTTr lubricated by skinny oil.
The spinning head was covered by the drum shell of the laying head for security which also tilting downward. There are a 2-3mm room between the inner diameter of the defense shell and the exterior diameter of the spinning head to make certain that the spinning head can function. The leading of the shell could be opened by two are cylinders to replace the laying tube. But the shell have to keep shut whilst doing work.
For all other elements on the cEPTTr shaft that rotate aEPTT with the shaft, they ought to all operate a static harmony test ahead of set up and alter the weigEPTT in accordance to the circumstances. Then a 700r/min dynamic stability test with the accuracy over G2.five diploma. Right after the installation of the EPTT program, a examination run is essential to make sure the vibration on two distinct places stay considerably less that four.5mm/s. The check places are found on the two bearing caps at every single facet of the cEPTTr shaft.
Due to the fact of the tilt, a block need to be welded on the foundation foundation to immobilize the EPT box of the laying head.
