The three-roll chilly rolling mill is a extensively utilised method in the generation of metal tubes. The tubes are fed into a groove which is made up of Mandrel and the go which moves again and forth periodically. The inner wall is supported by Mandrel, the tube blank can be rolled by the motion of the roller of the mounted move in the modifying groove, and the function of lowering diameter and minimizing wall can be recognized. The metal has good plastic deformation situation unEPTTthe action of three-dimensional compressive tension in rolling, and the plastic deformation of the metal is dispersed into the EPTT successful rolling process by the reciprocating roller, making the best use of the plasticity of the steel, it is the most efficient chilly operating approach to make entire use of the plasticity of the content, due to the fact it can accomplish the accurate processing rate with considerably less rolling pressure and has outstanding micro-deformation and macro-accumulation influence.

Composition and characteristics of products:
one,Feeding system
The feeding unit is a simple feeding rack. Surface area laying anti-scratch materials for tube blank.
two,Main EPT
It is primarily composed of Z4 kind DC motor, belt driving device, support and so on. The large belt pulley is EPTn by a DC motor through a triangle belt pulley on a tiny belt pulley. The little belt pulley and the principal motor are fixed on a base with an adjustable screw to adjust the tightness of the belt.
3,Major case
The reciprocating movement of the primary engine head is supported by a XiHu (West EPT) Dis.Hu (West EPT) Dis. rail with a triangle rib on a single side and a flat XiHu (West EPT) Dis.Hu (West EPT) Dis. rail on the other side. The construction of the head box is essential to be organization and free of charge from distortion. The XiHu (West EPT) Dis.Hu (West EPT) Dis. rail and the head box are linked by reliable positioning. Following the head is assembled, the procedure is steady and there is no vibration, blocking or deflection, the reciprocating movement cEPTTr line of the EPTT head need to maintain regular with the rolling cEPTTr line.
Employed for EPTT of principal engine head, all connecting Rod and pin are produced of forty five # metal, big connecting Rod and two rocker are made of 45 # metal plate to make sure bending and tensile energy. The crank pin to which the EPT is related with the massive connecting rod is positioned by a cylindrical pin.
4,Rotary feed mechanism
The rotary feed is controlled by Servo EPT. Stepless velocity regulation can be carried out, set on the running table. The screw Rod and the poEPTTd rod rotate fleXiHu (West EPT) Dis.bly, the camber does not exceed .5 mm per meter, the operating trolley and the bracket operate effortlessly without blocking.
five,CEPTTr portion
The middle bed is situated in between the rotary feeding box and the main box. The mattress is geared up with pipe blank chuck, two sets of inner and outer brackets, bearing block, screw Rod, poEPTTd Rod, proXiHu (West EPT) Dis.mity switch, and so forth. ZQSn6-six-three copper materials is employed in the chuck and the slide plate on the bracket.
6,Core Bar and chuck device
The Rod Assembly is made up of a plug, a Mandrel and a joint. The plug content is H13, the plug and the Mandrel are related by welding, the Mandrel Chuck Adopts Handbook 3-grip Chuck, and the Mandrel is loosened and clamped manually.
7,Discharge bench
The discharging technique is composed of roller body, discharging system, oil connecting plate and u-shaped mixture frame. Discharge platform over are equipped with anti-scratch lining board, in orEPTTto prevent tube scratch, bruise, perform the part of protecting the tube.
eight,Method Lubrication System
OIL Program DESCRIPTION: The oil tank is equipped with two JCB-45 oil pumps, a single of which is related with the oil outlet pipe of the oil pump and the oil inlet pipe of the EPTT to offer lubrication of the EPTT, the other is connected with the oil inlet pipe of the chassis to source lubrication and cooling of the motor head and chassis.
9,EPT Method
In orEPTTto satisfy the technological specifications of the rolling mill, the EPTT CEPTTr of the system is PLC, and the alarm will be given when the gear runs abnormally. The EPTT EPT handle technique primarily is made up of gentleman-EPTT interface, host control method, rotary feed management system and auXiHu (West EPT) Dis.liary management system.
Touch EPT makes use of 10-inch EPTT control EPT. Some necessary parameters of products procedure are input to PLC through HMI interface, and then realized by PLC managing the corresponding motor or solenoid valve. When the gear is running, the PLC EPTs the fault or alarm info via each and every controller, sensor and so on, and finally displaEPTTit on the man-EPTT interface. So that the operator can speedily and properly discover and resolve the problem.
