Composition and traits of equipment:
The feeding gadget is composed of a feeding platform, a feeding raceway, a EPT wheel EPTT system and a pipe jacking. Right after the main rod is clamped and the 3 jaws are opened, the frequency conversion motor is activated through the sprocket EPT to EPT the pipe jacking trolley EPTT, and the pipe jacking in JCEP of the pipe jacking trolley sends the billet into the lathe mattress before the trolley, reverse commence sprocket EPTT unit out of the pipe, main rod clamping a few claw clamping main Rod, rolling mill commence, at the exact same time back to the back again limit pipe, by way of the cylinEPTTpull pull pull pull pull pull the billet tube to the feeding roller, the pipe jacking EPT speedily sends the pipe blank to the JCEP restrict and waits for the next feeding. By means of the encoEPTTreading powering the sprocket shaft, the duration of every tube blank is calculated, so that the mattress is despatched into the trolley for the tube blank rapidly rear-end collision.
2,Main Bar Chuck Assembly
The core bar chuck adopts EPT stress type. The loosening and clamping of the core rod are accompEPTTd by the EPT cylinder. The aXiHu (West EPT) Dis.al adjustable stroke of the core bar chuck is plusmn 35mm to make sure the dimension requirement of the finished pipe.
three,Rotary feed system
The rotary feeding system is managed by servo motor or DC motor. The dimensions of the rotation angle and the size of the feed by shifting the number of motor rotation to accomplish stepless adjustment. The rotary feeding mechanism is outfitted with a feeding motor and a rotary motor. The tube blank is intermittently fed and rotated by way of a EPT reduction system respectively.
The center bed is manufactured up of mattress, tube blank, carriage, bearing seat, screw Rod, easy lubricating gadget and so on. The middle mattress adopts the welding mattress, and the welding components are annealed. The EPTT entire body is equipped with double bearing housing to EPT the direct pipe blank into the trolley pull rod bracket, poEPTTd rod and so on. The two driving screws are fixed in the JCEP and again bearing seats, one particular conclude of which is connected with a hexagonal coupling and a rotary feeding box, and the intermittent feeding of the pipe is realized by the screw nut installed in the pipe billet feeding trolley, screw Rod EPT: EPT JCEP Rod EPT YF45MnV. The bracket supports the screw Rod, the core rod and the tube blank. In the method of EPT Rolling, the tube blank is fed into the tube blank intermittently at the again conclude of the tube blank. When the tube blank is fed into the tube blank, the tube blank into the roof sleeve must be changed to suit the various requirements of the tube blank. In the method of stopping and charging, the billet can be moved into the trolley to manage the fast EPT and retreat and cease at any situation of the middle mattress. The straightforward lubrication unit for the screw Rod lubricates the screw rod irregularly to increase the services lifestyle of the screw nut.
The box physique uses the welding piece, the welding piece carries on the anneal processing and the leakage take a look at. In orEPTTto faXiHu (West EPT) Dis.Hu (West EPT) Dis.tate the cleaning of the box physique and avoid the accumulation of dirt, a diversion plate is included on the reinforcing rib of the box entire body. The chassis is equipped with a shut upper protect, which is handy for computerized operation in style and can avoid the splash of process lubricant and h2o spray out of the EPTT and decrease sounds. The primary and passive enamel are lubricated by oil EPT. EPT content: huge EPT ZG310-570. Pinion forgings 40CR. (other components and processes can be employed in accordance to customer’s demands) the connecting rod adopts 45 # , normalizing. The driving shaft and connecting Rod Pin are quenched and tempered with 40Cr. Rack materials: forty five, tooth surface area quenching therapy. EPTT Base XiHu (West EPT) Dis.HU (WEST LAKE) DIS. RAIL: the XiHu (West EPT) Dis.hu (West EPT) Dis. rail adopts independent or integral construction, the materials is EPTT300 casting. EPTTs are lubricated with grease.
The discharging unit is composed of a concluded solution pulling device, an oil scraping device, a discharge raceway, a concluded merchandise substance rack and an oil pan. The JCEP EPTT Technique automatically calculates when the end of a concluded tube is a particular length from the finish of the tube to the limit situation before it is sent into the trolley, signals are sent to the motor of the EPTT of the concluded solution pulling system, and the finished tube is speedily pulled into the discharge raceway, when the EPTT completed tube is pulled out, the cylinEPTTin the discharge raceway turns the concluded tube into the finished content rack. Oil Pan is utilised to EPT the residual oil on the finished product tube to defend the site atmosphere.
7,Principal EPT mechanism
It consists of Z4 DC motor, belt EPT, EPT Disc brake and help. The uEPTTty design is utilised for driving the operating body of the chilly pipe rolling mill and creating it reciprocating. The program employs 3-period silicon controlled rectifier, Z 4 series DC motor to EPT the trigonometric belt, which is transmitted to a pair of driving EPTs in the chassis by means of a large pulley. The driving EPTs are engaged with the crank EPTs, then through the crank and connecting rod EPT the perform rack for reciprocating motion. In orEPTTto permit the rack to end at a set situation (the little opening of the roller) , a EPT Disc brake is mounted on the assistance and related 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 support.
The EPT program comprises a EPT station oil pump, a gasoline tank unit, a corresponding electromagnetic control valve and a pipeline. EPT Program by way of force handle valve, flow management valve, solenoid valve to control the precision of each and every EPT cylinEPTTto guarantee the normal procedure of the EPTT rolling method. The EPT cylinEPTTcomprises a main Rod Chuck Oil CylinEPTT(1 medium and minimal force) .
nine,Process Lubrication Method
The cooling pump is mounted on a separate oil tank the oil is shipped to the head by a EPTTting mechanism to supply approach lubrication and cooling of the tube blank, as properly as lubrication of the XiHu (West EPT) Dis.Hu (West EPT) Dis.way, head slide and EPT rack in the body.
ten,EPT EPTT Technique
The main motor speed control system and the motor EPT program managed by PLC are composed of electrical control cabinet and operation panel. The EPTT CEPTTr of the system is Plc.. The EPTT EPT control program primarily is made up of EPTT control method, rotary feed handle method, auXiHu (West EPT) Dis.liary management system and so on.
