Product description:
LD-one hundred eighty is 5-roll profile-Chilly Rolling Mill, The mechanical products of rolling mill incEPTTs feed unit, mandrel parts, EPT mandrel chuck, rotating feed mechanism, middle mattress elements, frame, working body, discharge device and major EPT mechanism, which can satisfy the generation needs of stainless metal. superalloy. EPTTium and EPTTium alloEPTTand other black Non-ferrous metal are precision seamless, agent steel grades are as follows:

The 5-roll chilly rolling mill is a broadly used technique in the creation of metallic tubes. The tubes are fed into a groove which is produced up of Mandrel and the move which moves back again and forth periodically. The internal wall is supported by Mandrel, the tube blank can be rolled by the motion of the roller of the fastened pass in the modifying groove, and the perform of reducing diameter and decreasing wall can be recognized. The metallic has good plastic deformation issue unEPTTthe action of three-dimensional compressive pressure in rolling, and the plastic deformation of the metal is dispersed into the EPTT effective rolling procedure by the reciprocating roller, making the very best use of the plasticity of the steel, it is the most powerful cold functioning technique to make full use of the plasticity of the substance, since it can obtain the correct processing fee with much less rolling power and has outstanding micro-deformation and macro-accumulation influence.

Construction and qualities of gear:
one,Feeding system
The feeding unit is composed of a feeding system, a feeding raceway, a EPT wheel EPTT gadget and a pipe jacking. Right after the core rod clamping 3 claws open up, the starting up button, the motor by way of the sprocket EPTT system, driving the pipe jacking cart EPTT, by the pipe jacking set up in entrance of the pipe jacking cart to deliver the billet into the mattress before the cart, beginning the sprocket EPT in the opposite course to eXiHu (West EPT) Dis.t the pipe jacking, clamping the core rod with the core rod and clamping the 3 claws, beginning the mill to carry out the rolling, at the identical time pushing the pipe back again to the back limit, by way of the cylinEPTTpulling the substance pulling mechanism to change the billet pipe to the materials feeding raceway, the pipe jacking EPT slowly and gradually delivers the pipe blank to the entrance limit situation and waits for the next feeding.
2,Primary EPT
It is made up of Z4 DC motor, belt EPT, EPT Disc brake and assistance. The uEPTTty product is used for driving the working body of the chilly pipe rolling mill and making it reciprocating. The technique employs three-phase silicon managed rectifier, Z four collection DC motor to EPT the trigonometric belt, which is transmitted to a pair of driving EPTs in the chassis by way of a large pulley. The driving EPTs are engaged with the crank EPTs, then by means of the crank and connecting rod EPT the function rack for reciprocating movement. In orEPTTto permit the rack to quit at a set situation (the tiny opening of the roller) , a EPT Disc brake is mounted on the support 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 device
The box physique uses the welding piece, the welding piece carries on the anneal processing and the leakage test. An upper go over is offered on the chassis to avert the splash of the method lubricant and minimize the sound. The EPTT transmitted from the driving element is transmitted to the driving shaft via the coupling, by way of the driving helical EPT, driving the huge connecting rod put in on the huge eccentric helical EPT, the other conclude of the massive connecting rod is linked with the rocker rod, as a result producing the rocker mechanism swing again and forth. EPT materials: huge EPT ZG310-570. Pinion forgings for 40Gr. EPTing rod adopt 45 # , normalizing. EPTing Rod Pin, EPT shaft material for 40Cr, conditioning remedy. The eccentric EPT is lubricated by splash and the bearing is lubricated by grease.
The higher end of the rocker is related with the EPTT head by way of an upper 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 go respectively, so that the roller and the slide observe are in relative movement, as the Rolls Roll on the sXiHu (West EPT) Dis.Hu (West EPT) Dis.e of the slide, the go shaped by the 5 rolls may differ periodically from huge to small (constructive stroke) or from modest to big (reverse stroke) . This spherical-the-clock reciprocating motion is the multi-roll cold mill rolling approach. The head slide plate is made of QAL-9-4 copper, the body sleeve and trolley are manufactured of integral cast steel, and the material is ZG310-570 roll content is GCR15.

4,Rotary feed mechanism
The rotary feed is controlled by Servo EPT. When the EPTT head moves to the back again beginning stage, the signals are sent to the PLC by way of the sensor, and the PLC respectively instructs the pipe chuck in the center mattress to rotate and feed, in orEPTTto satisfy the requirements of head rolling pipe. The rotation angle is held continual every time, stepless adjustable the magnitude of feed quantity is realized by PLC management Servo EPT rotation angle, and stepless adjustable. The box physique is welded by steel plate, and the EPTT body is tempered.

5,CEPTTr portion
The center mattress is positioned in between the rotary feeding box and the main 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 swap, and so on. The substance of screw rod: EPT Screw Rod EPT YF45MnV ZQSn6-six-3 copper plate structure is adopted in the chuck and slide plate on the bracket of the internal pipe entire body of the lathe bed In orEPTTto increase the stability, the mattress assistance utilizes 4 coaming to weld into the square box.

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

7,Discharge bench
The discharging technique is composed of roller body, discharging system, oil acquiring plate (made by consumers on their own) and u-formed aggregate frame. The discharging system is each welded physique, and the discharging system is equipped with anti-scratch lining board to stop the pipe content from being scratched and bruised, which plaEPTTthe position of defending the pipe materials.
8,Approach Lubrication Technique
The approach lubricant is manufactured up of rolling oil (reusable) , oil tank, pump-motor device, pipe fittings, etc. . It is used to amazing and lubricate roll move in rolling method, 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 utilised to amazing and lubricate the work 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 metal pipe.
nine,EPT System
In orEPTTto fulfill the technological specifications of the rolling mill, the EPTT CEPTTr of the program is Plc.. The EPTT EPT management method primarily consists of male-EPTT interface, host management technique, rotary feed handle technique, pneumatic manage and auXiHu (West EPT) Dis.liary control method. All minimal-voltage switches, contactors, relays, etc. are picked domestic first-line items.
The guy-EPTT interface employs a ten-inch touch EPT. Some essential parameters of equipment operation are input to PLC by means of male-EPTT interface, and then realized by PLC managing the corresponding motor or solenoid valve. When the equipment is working, the PLC EPTs the fault or alarm details through every controller, sensor and so on, and finally displaEPTTit on the gentleman-EPTT interface. So that the operator can swiftly and properly identify and remedy the difficulty.
