Pinch Roll amp Laying EPT for Wire Rod Manufacturing Line
one. EPT Apps
The pinch roller and the laying head had been established following the h2o-cooling program of the finishing mills. The pinch roll will grip the operate piece and send it into the laying head to lengthen the wire rods into 1080mm spiral coils with rotation before they have been sent to the cooling program.

3. The Structural Characteristics of the Pinch Roll
Pinch roll and laying head are two separate areas which shut attached to every single other. The pinch roll was set at the entrance of the laying head to grip the work piece and feed it into the laying head. The laying head then will extend the wire rods into 1080mm spiral coils and send out them to the pursuing cooling program.
The double roll pinch roll with a horizontal cantiEPT structure can clamp EPTTltaneously by the EPTT of the air cylinder. The pinch roll itself was EPTTed by a DC motor and a two-phase EPT box. Two rolls had been set up independently on two diverse swinging arms and EPTn by a cylinder-crank program to clamp. To make positive that the rolling piece would not be above-rolled, the clamp drive can be preset and modified. The adjustable restrainer can guarantee two rolls remain untouched from every other with a minimum cEPTTr distance in between two rolls and a maXiHu (West EPT) Dis.mum opening diploma. The human body box of the pinch roll was welded and the EPTs and large speed filmatic bearings inside of had been cEPTTr lubricated by slim oil. The pinch roll will keep running for the duration of daily performs and its speed was deterEPTd by the true continuing procedures although the rolling piece it carries could be clamped by the head, the exceptional or the EPTT method.
The laying head is horizontal and tilted fifteen deg downward. The major laying system was one particular laying tube mounted on the cEPTTr shaft and the EPTT system. The cEPTTr rotating shaft was EPTTed by a pair of EPTTl EPTs and one particular DC motor. The laying tube can rotate at a specified speed as preset to lay coils with normal diameter.
The cEPTTr rotating shaft of the laying head includes two parts, the spinning head and the hollow shaft with a tube was inserted in. The cooling jacket was installed among the tube and the hollow shaft to steer clear of the heat EPTT to the bearings attached to the hollow shaft.
The human body box of the laying head was welded and the EPTs and bearings inside ended up cEPTTr lubricated by slender oil.
The spinning head was coated by the drum shell of the laying head for security which also tilting downward. There are a two-3mm room between the inner diameter of the safety shell and the external diameter of the spinning head to make confident that the spinning head can work. The best of the shell could be opened by two are cylinders to replace the laying tube. But the shell should continue to be shut whilst working.
For all other parts on the cEPTTr shaft that rotate aEPTT with the shaft, they ought to all operate a static stability take a look at just before set up and change the weigEPTT in accordance to the circumstances. Then a 700r/min dynamic stability check with the accuracy previously mentioned G2.five degree. Following the installation of the EPTT system, a examination run is necessary to make confident the vibration on two various places continue to be considerably less that four.5mm/s. The check spots are located on the two bearing caps at each and every facet of the cEPTTr shaft.
Simply because of the tilt, a block need to be welded on the foundation basis to immobilize the EPT box of the laying head.
