one. EPTT Applications
The pinch roller and the laying head had been established soon after the h2o-cooling method of the finishing mills. The pinch roll will grip the function piece and send it into the laying head to lengthen the wire rods into 1080mm spiral coils with rotation prior to they have been sent to the cooling system.

3. The Structural Functions of the Pinch Roll
Pinch roll and laying head are two individual parts which closed connected to every single other. The pinch roll was established at the entrance of the laying head to grip the function piece and feed it into the laying head. The laying head then will lengthen the wire rods into 1080mm spiral coils and send them to the adhering to cooling program.
The double roll pinch roll with a horizontal cantiEPTT construction can clamp EPTTltaneously by the EPTT of the air cylinder. The pinch roll alone was EPTTed by a DC motor and a two-phase EPTT box. Two rolls were installed separately on two different swinging arms and EPTTn by a cylinder-crank system to clamp. To make confident that the rolling piece would not be over-rolled, the clamp drive can be preset and modified. The adjustable restrainer can assure two rolls keep untouched from every other with a bare minimum cEPTTr length amongst two rolls and a maXiHu (West Lake) Dis.mum opening degree. The physique box of the pinch roll was welded and the EPTTs and substantial pace filmatic bearings inside of have been cEPTTr lubricated by slim oil. The pinch roll will stay working throughout daily works and its speed was deterEPTTd by the actual continuing processes although the rolling piece it carries could be clamped by the head, the unusual or the EPTT procedure.
The laying head is horizontal and tilted 15 deg downward. The primary laying system was one particular laying tube set up on the cEPTTr shaft and the EPTT system. The cEPTTr rotating shaft was EPTTed by a pair of EPTTl EPTTs and one DC motor. The laying tube can rotate at a specified pace as preset to lay coils with standard diameter.
The cEPTTr rotating shaft of the laying head is made up of two parts, the spinning head and the hollow shaft with a tube was inserted in. The cooling jacket was put in among the tube and the hollow shaft to steer clear of the warmth EPTT to the bearings hooked up to the hollow shaft.
The human body box of the laying head was welded and the EPTTs and bearings inside of have been cEPTTr lubricated by skinny oil.
The spinning head was lined by the drum shell of the laying head for security which also tilting downward. There are a two-3mm room amongst the interior diameter of the safety shell and the exterior diameter of the spinning head to make positive that the spinning head can work. The top of the shell could be opened by two are cylinders to substitute the laying tube. But the shell need to continue to be closed while functioning.
For all other components on the cEPTTr shaft that rotate aEPTT with the shaft, they must all operate a static equilibrium test just before installation and change the weigEPTT according to the conditions. Then a 700r/min dynamic balance take a look at with the precision above G2.five degree. After the set up of the EPTT technique, a examination operate is required to make positive the vibration on two distinct places remain much less that four.5mm/s. The take a look at places are found on the two bearing caps at every aspect of the cEPTTr shaft.
Due to the fact of the tilt, a block ought to be welded on the base foundation to immobilize the EPTT box of the laying head.
