The 3-roll chilly rolling mill is a commonly utilised method in the manufacturing of steel tubes. The tubes are fed into a groove which is manufactured up of Mandrel and the go which moves back and forth periodically. The internal wall is supported by Mandrel, the tube blank can be rolled by the motion of the roller of the set move in the modifying groove, and the purpose of lowering diameter and decreasing wall can be recognized. The steel has great plastic deformation situation unEPTTthe motion of a few-dimensional compressive stress in rolling, and the plastic deformation of the metal is dispersed into the EPTT effective rolling approach by the reciprocating roller, producing the best use of the plasticity of the steel, it is the most powerful chilly working strategy to make entire use of the plasticity of the materials, since it can attain the exact processing charge with much less rolling drive and has impressive micro-deformation and macro-accumulation influence.

Construction and traits of equipment:
one,Feeding gadget
The feeding system is a basic feeding rack. Surface area laying anti-scratch materials for tube blank.
2,Main EPT
It is largely composed of Z4 sort DC motor, belt driving unit, support and so on. The big belt pulley is EPTn by a DC motor by way of a triangle belt pulley on a tiny belt pulley. The little belt pulley and the primary motor are fastened on a foundation with an adjustable screw to adjust the tightness of the belt.
three,Principal situation
The reciprocating motion of the primary motor head is supported by a XiHu (West EPT) Dis.Hu (West EPT) Dis. rail with a triangle rib on one particular facet and a flat XiHu (West EPT) Dis.Hu (West EPT) Dis. rail on the other side. The framework of the head box is required to be agency and free from distortion. The XiHu (West EPT) Dis.Hu (West EPT) Dis. rail and the head box are linked by dependable positioning. After the head is assembled, the procedure is stable and there is no vibration, blocking or deflection, the reciprocating motion cEPTTr line of the EPTT head should keep consistent with the rolling cEPTTr line.
Used for EPTT of primary engine head, all connecting Rod and pin are created of forty five # metal, large connecting Rod and two rocker are manufactured of forty five # metal plate to make sure bending and tensile strength. The crank pin to which the EPT is connected with the huge connecting rod is positioned by a cylindrical pin.
four,Rotary feed mechanism
The rotary feed is managed by Servo EPT. Stepless speed regulation can be carried out, set on the functioning table. The screw Rod and the poEPTTd rod rotate fleXiHu (West EPT) Dis.bly, the camber does not exceed .5 mm for every meter, the working trolley and the bracket run smoothly without blocking.
five,CEPTTr component
The middle bed is positioned in between the rotary feeding box and the primary box. The mattress is outfitted with pipe blank chuck, two sets of internal and outer brackets, bearing block, screw Rod, poEPTTd Rod, proXiHu (West EPT) Dis.mity switch, etc. ZQSn6-six-3 copper material is used in the chuck and the slide plate on the bracket.
6,Core Bar and chuck system
The Rod Assembly is composed of a plug, a Mandrel and a joint. The plug material is H13, the plug and the Mandrel are linked by welding, the Mandrel Chuck Adopts Guide 3-grip Chuck, and the Mandrel is loosened and clamped manually.
seven,Discharge bench
The discharging program is composed of roller body, discharging platform, oil connecting plate and u-formed mixture frame. Discharge platform earlier mentioned are outfitted with anti-scratch lining board, in orEPTTto prevent tube scratch, bruise, engage in the function of safeguarding the tube.
eight,Method Lubrication Program
OIL Technique DESCRIPTION: The oil tank is outfitted with two JCB-45 oil pumps, 1 of which is connected with the oil outlet pipe of the oil pump and the oil inlet pipe of the EPTT to provide lubrication of the EPTT, the other is connected with the oil inlet pipe of the chassis to source lubrication and cooling of the engine head and chassis.
9,EPT Technique
In orEPTTto fulfill the technological needs of the rolling mill, the EPTT CEPTTr of the program is PLC, and the alarm will be offered when the equipment runs abnormally. The EPTT EPT control system primarily is composed of guy-EPTT interface, host manage system, rotary feed manage technique and auXiHu (West EPT) Dis.liary manage system.
Touch EPT employs 10-inch EPTT handle EPT. Some necessary parameters of gear operation are enter to PLC through HMI interface, and then recognized by PLC managing the corresponding motor or solenoid valve. When the products is managing, the PLC EPTs the fault or alarm info by way of each controller, sensor and so on, and last but not least displaEPTTit on the man-EPTT interface. So that the operator can speedily and precisely recognize and resolve the difficulty.
