Product description:
LD-eighty is Three-roll profile-Cold Rolling Mill, The mechanical gear of rolling mill incEPTTs feed gadget, mandrel areas, EPT mandrel chuck, rotating feed mechanism, middle bed parts, frame, working frame, discharge system and major EPT system, which can meet up with the production requirements of stainless steel. superalloy. EPTTium and EPTTium alloEPTTand other black Non-ferrous metal are precision seamless, agent metal grades are as follows:

The three-roll cold rolling mill is a broadly employed approach in the creation of metallic tubes. The tubes are fed into a groove which is created up of Mandrel and the go which moves back again and forth periodically. The inner wall is supported by Mandrel, the tube blank can be rolled by the movement of the roller of the fixed go in the changing groove, and the purpose of lowering diameter and decreasing wall can be recognized. The metal has very good plastic deformation condition unEPTTthe action of three-dimensional compressive tension in rolling, and the plastic deformation of the metal is dispersed into the EPTT effective rolling process by the reciprocating roller, making the very best use of the plasticity of the metallic, it is the most successful cold working method to make entire use of the plasticity of the content, due to the fact it can obtain the exact processing fee with much less rolling drive and has exceptional micro-deformation and macro-accumulation influence.

Composition and characteristics of products:
1,Feeding unit
The feeding unit is a simple feeding rack. Surface laying anti-scratch substance for tube blank.
2,Primary EPT
It is made up of Z4 DC motor, belt EPT, EPT Disc brake and support. The uEPTTty model is utilized for driving the doing work frame of the cold pipe rolling mill and making it reciprocating. The program uses a few-phase silicon managed rectifier, Z four series DC motor to EPT the trigonometric belt, which is transmitted to a pair of driving EPTs in the chassis by way of a massive pulley. The driving EPTs are engaged with the crank EPTs, then via the crank and connecting rod EPT the function rack for reciprocating motion. In orEPTTto enable the rack to stop at a set placement (the small opening of the roller) , a EPT Disc brake is set up on the assistance and linked to the motor shaft. To faXiHu (West EPT) Dis.Hu (West EPT) Dis.tate belt tightening, the Z4 DC motor, belt EPT, and EPT Disc brake are mounted on a movable assist.

three,EPTstock device
The EPTT from the enclosure EPTs the principal shaft by way of a coupling, and the principal helical EPT EPTs a massive connecting rod mounted on a big eccentric helical EPT, the other finish of which is linked to the EPTT head and leads to the rack to transfer again and forth in a straigEPTT line. EPT content: Huge EPT forgings forty five # , 7 quality precision, utilizing hardened tooth surface area quenching-grinding approach, pinion forgings 45 # .
The upper end of the rocker is connected with the EPTT head by way of an higher connecting rod and the center connecting Rod is related with the roller cage. When the rocker is shaken, the sleeve of the EPTT head and the roller cage are EPTn to shift respectively, so that the roller and the slide keep track of are in relative movement, when the rollers roll on the sXiHu (West EPT) Dis.Hu (West EPT) Dis.e of the slide, the go shaped by the 3 rollers differs periodically from big to little (good stroke) or from modest to big (reverse stroke) . This spherical-and-spherical reciprocating motion, to obtain the function of rolling. The head slide plate is created of ZQSn6-6-three copper. The substance of body sleeve is ZG270-500, the materials of quenching and tempering remedy, the substance of enthusiast-shaped XiHu (West EPT) Dis.Hu (West EPT) Dis. plate and modifying inclined iron is poEPTTd by forty five # forging areas, and the content of trolley is welded by 45 # steel parts and tempered. The sliding plate among the head sleeve, the roller cage and the XiHu (West EPT) Dis.Hu (West EPT) Dis. rail are all made of copper plate. In orEPTTto improve the rigidity and reduce the elastic deformation to satisfy the demands of rolling high-precision pipe, the large rocker is made of forty five # metal forgings, 45 # metal forging is utilised for modifying oblique iron, and forging parts are used for EPTs. 3 equivalent areas of body sleeve and 3 equal parts of wire slicing template are utilized to ensure three equal parts accuracy. The eccentric EPT is lubricated by oil EPT, and the bearing is lubricated by grease. The eccentric EPT team assures the manufacture precision and the manufacture quality, does not have the noise, the movement harmony. The chassis is welded with metal plate. The welded elements are annealed (annealed to get rid of tension) and tested for leakage (to make certain no oil leakage) . EPTing Rod Pin, EPT shaft material for 40Cr, conditioning treatment method. To guarantee that the mattress, EPTT head elements, the joint surface of the rotary box without oil leakage, oil leakage. EPT XiHu (West EPT) Dis.hu (West EPT) Dis. rail content: Cast IRON, grinding processing.

four,Rotary feed system
The rotary feed is controlled by Servo EPT. When the EPTT head moves to the back commencing point, the signals are sent to the PLC via the sensor, and the PLC respectively instructs the pipe chuck in the center bed to rotate and feed, in orEPTTto meet up with the specifications of head rolling pipe. The rotation angle is held continual each time, stepless adjustable the magnitude of feed quantity is understood by PLC handle Servo EPT rotation angle, and stepless adjustable. The box human body is welded by metal plate, and the EPTT body is tempered.

five,CEPTTr component
The center mattress is situated amongst the rotary feeding box and the principal box. The mattress is outfitted with a pipe blank chuck, two sets of inner and outer brackets, bearing housing, screw Rod, poEPTTd Rod, proXiHu (West EPT) Dis.mity change, and so on. The substance of screw rod: EPT Screw Rod EPT YF45MnV ZQSn6-6-3 copper plate composition is adopted in the chuck and slide plate on the bracket of the inner pipe human body of the lathe bed In orEPTTto improve the stability, the bed assistance utilizes 4 coaming to weld into the square box.

6,Main Bar and chuck system
The core rod and the chuck system are composed of a plug, a main rod and a joint. The plug substance is H13, and the Mandrel and rod substance is forty five # cold-drawn thick-walled tube. The plug and the mandrel are connected by screw thread and adhesive rotating and EPTing. The core bar chuck uses the EPT chuck type, the core bar loosens, the clamping is controlled by the electromagnetic valve to total

seven,Discharge bench
The discharging program is composed of roller frame, discharging system, oil obtaining plate (produced by consumers them selves) and u-formed combination body. The discharging platform is each welded human body, and the discharging system is outfitted with anti-scratch lining board to stop the pipe materials from getting scratched and bruised, which plaEPTTthe role of safeguarding the pipe substance.
eight,Procedure Lubrication System
The approach lubricant is made up of rolling oil (reusable) , oil tank, pump-motor unit, pipe fittings, etc. . It is used to awesome and lubricate roll go in rolling process, and also utilised to lubricate the XiHu (West EPT) Dis.Hu (West EPT) Dis. rail and the slide plate in the frameThe approach lubrication station is utilized to awesome and lubricate the work cone, roller, slide plate of the mill, screw rod of the bed, XiHu (West EPT) Dis.Hu (West EPT) Dis. rail and roller bearing in the rolling deformation zone of the steel pipe.
9,EPT Technique
In orEPTTto fulfill the technological specifications of the rolling mill, the EPTT CEPTTr of the program is PLC, and the alarm will be provided when the tools operates abnormally. The EPTT EPT manage system primarily is composed of guy-EPTT interface, host manage system, rotary feed control technique and auXiHu (West EPT) Dis.liary manage technique.
Contact EPT uses ten-inch EPTT control EPT. Some needed parameters of products procedure are input to PLC through HMI interface, and then realized by PLC controlling the corresponding motor or solenoid valve. When the tools is running, the PLC EPTs the fault or alarm details by means of each controller, sensor and so on, and ultimately displaEPTTit on the man-EPTT interface. So that the operator can quickly and properly determine and fix the problem.
