Product description:
LD-one hundred twenty is 3-roll profile-Chilly Rolling Mill, The mechanical gear of rolling mill incEPTTs feed device, mandrel elements, EPT mandrel chuck, rotating feed mechanism, middle mattress areas, body, doing work body, discharge unit and major EPT mechanism, which can meet the creation needs of stainless steel. superalloy. EPTTium and EPTTium alloEPTTand other black Non-ferrous steel are precision seamless, consultant metal grades are as follows:

The 3-roll chilly rolling mill is a extensively utilized strategy in the production of metallic tubes. The tubes are fed into a groove which is created up of Mandrel and the move which moves back and forth periodically. The interior wall is supported by Mandrel, the tube blank can be rolled by the movement of the roller of the mounted go in the modifying groove, and the perform of minimizing diameter and lowering wall can be realized. The steel has very good plastic deformation problem unEPTTthe motion of 3-dimensional compressive anxiety in rolling, and the plastic deformation of the steel is dispersed into the EPTT powerful rolling approach by the reciprocating roller, creating the very best use of the plasticity of the metal, it is the most successful chilly operating method to make full use of the plasticity of the substance, because it can accomplish the accurate processing charge with considerably less rolling pressure and has exceptional micro-deformation and macro-accumulation impact.

Structure and characteristics of gear:
one,Feeding unit
The feeding device is composed of a feeding platform, a feeding raceway, a EPT wheel EPTT device and a pipe jacking. Soon after the main rod clamping a few claws open up, the commencing button, the motor via the sprocket EPTT system, driving the pipe jacking cart EPTT, by the pipe jacking installed in entrance of the pipe jacking cart to send the billet into the bed just before the cart, beginning the sprocket EPT in the opposite course to eXiHu (West EPT) Dis.t the pipe jacking, clamping the main rod with the core rod and clamping the 3 claws, starting the mill to carry out the rolling, at the very same time pushing the pipe back again to the back restrict, by way of the cylinEPTTpulling the substance pulling system to shift the billet pipe to the substance feeding raceway, the pipe jacking EPT gradually delivers the pipe blank to the entrance limit place and waits for the subsequent feeding.
two,Major EPT
It is made up of Z4 DC motor, belt EPT, EPT Disc brake and assistance. The uEPTTty design is utilized for driving the operating frame of the chilly pipe rolling mill and creating it reciprocating. The program makes use of three-period silicon controlled rectifier, Z four sequence DC motor to EPT the trigonometric belt, which is transmitted to a pair of driving EPTs in the chassis through a big pulley. The driving EPTs are engaged with the crank EPTs, then through the crank and connecting rod EPT the work rack for reciprocating movement. In orEPTTto permit the rack to quit at a set situation (the little opening of the roller) , a EPT Disc brake is put in on the help 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 assistance.

three,EPTstock unit
The box physique employs the welding piece, the welding piece carries on the anneal processing and the leakage check. An higher protect is supplied on the chassis to avert the splash of the procedure lubricant and lessen the sounds. The EPTT transmitted from the driving part is transmitted to the driving shaft via the coupling, through the driving helical EPT, driving the large connecting rod set up on the large eccentric helical EPT, the other conclude of the big connecting rod is linked with the rocker rod, therefore making the rocker mechanism swing again and forth. EPT substance: massive EPT ZG310-570. Pinion forgings for 40Gr. EPTing rod adopt 45 # , normalizing. EPTing Rod Pin, EPT shaft material for 40Cr, conditioning treatment. The eccentric EPT is lubricated by splash and the bearing is lubricated by grease.
The higher stop of the rocker is linked with the EPTT head through an upper connecting rod and the middle connecting Rod is linked with the roller cage. When the rocker is shaken, the sleeve of the EPTT head and the roller cage are EPTn to transfer 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 pass fashioned by the three rollers may differ periodically from huge to small (optimistic stroke) or from small to large (reverse stroke) . This round-the-clock reciprocating motion is the multi-roll cold mill rolling process. The head slide plate is produced of QAL-nine-four copper, the body sleeve and trolley are made of integral forged metal, and the material is ZG310-570 roll content is GCR15.

four,Rotary feed mechanism
The rotary feed is managed by Servo EPT. When the EPTT head moves to the back beginning position, the indicators are sent to the PLC by means of the sensor, and the PLC respectively instructs the pipe chuck in the center mattress to rotate and feed, in orEPTTto fulfill the demands of head rolling pipe. The rotation angle is retained consistent every single time, stepless adjustable the magnitude of feed amount is recognized by PLC control Servo EPT rotation angle, and stepless adjustable. The box human body is welded by steel plate, and the EPTT physique is tempered.

five,CEPTTr component
The center mattress is found amongst the rotary feeding box and the major box. The mattress is geared up with a pipe blank chuck, two sets of interior and outer brackets, bearing housing, screw Rod, poEPTTd Rod, proXiHu (West EPT) Dis.mity switch, etc. The materials of screw rod: EPT Screw Rod EPT YF45MnV ZQSn6-six-3 copper plate construction is adopted in the chuck and slide plate on the bracket of the inner pipe physique of the lathe mattress In orEPTTto boost the stability, the mattress assistance uses 4 coaming to weld into the square box.

six,Core Bar and chuck device
The core rod and the chuck unit are composed of a plug, a core rod and a joint. The plug material is H13, and the Mandrel and rod materials is forty five # cold-drawn thick-walled tube. The plug and the mandrel are linked by screw thread and adhesive rotating and EPTing. The main bar chuck utilizes the EPT chuck kind, the core bar loosens, the clamping is managed by the electromagnetic valve to comprehensive

seven,Discharge bench
The discharging technique is composed of roller body, discharging platform, oil receiving plate (made by buyers by themselves) and u-formed aggregate body. The discharging platform is every welded physique, and the discharging platform is equipped with anti-scratch lining board to avoid the pipe materials from getting scratched and bruised, which plaEPTTthe part of protecting the pipe content.
eight,Procedure Lubrication Method
The procedure lubricant is created up of rolling oil (reusable) , oil tank, pump-motor device, pipe fittings, and many others. . It is used to amazing and lubricate roll pass in rolling process, and also utilized to lubricate the XiHu (West EPT) Dis.Hu (West EPT) Dis. rail and the slide plate in the frameThe procedure lubrication station is utilised to awesome and lubricate the function cone, roller, slide plate of the mill, screw rod of the mattress, XiHu (West EPT) Dis.Hu (West EPT) Dis. rail and roller bearing in the rolling deformation zone of the steel pipe.
nine,EPT Method
In orEPTTto meet the technological demands of the rolling mill, the EPTT CEPTTr of the method is Plc.. The EPTT EPT control technique primarily consists of gentleman-EPTT interface, host control technique, rotary feed control program, pneumatic management and auXiHu (West EPT) Dis.liary manage program. All low-voltage switches, contactors, relays, and so on. are picked domestic very first-line items.
The male-EPTT interface makes use of a ten-inch contact EPT. Some essential parameters of gear operation are enter to PLC by means of man-EPTT interface, and then understood by PLC controlling the corresponding motor or solenoid valve. When the tools is managing, the PLC EPTs the fault or alarm information by way of every single controller, sensor and so on, and lastly displaEPTTit on the gentleman-EPTT interface. So that the operator can swiftly and precisely discover and resolve the difficulty.
