Structure and attributes of products:
one,Feeding gadget
The feeding device is composed of a feeding system, a feeding raceway, a chain wheel transmission gadget and a pipe jacking. After the main rod is clamped and the three jaws are opened, the frequency conversion motor is activated through the sprocket travel to travel the pipe jacking trolley CZPT, and the pipe jacking in entrance of the pipe jacking trolley sends the billet into the lathe mattress before the trolley, reverse commence sprocket transmission gadget out of the pipe, core rod clamping a few claw clamping core Rod, rolling mill commence, at the exact same time back again to the again limit pipe, through the cylinder pull pull pull pull pull pull the billet tube to the feeding roller, the pipe jacking truck speedily sends the pipe blank to the entrance restrict and waits for the subsequent feeding. By means of the encoder looking through powering the sprocket shaft, the size of each and every tube blank is calculated, so that the mattress is despatched into the trolley for the tube blank rapidly rear-stop collision.

two,Main Bar Chuck Assembly
The main bar chuck adopts hydraulic stress sort. The loosening and clamping of the main rod are accomplished by the hydraulic cylinder. The axial adjustable stroke of the main bar chuck is ± 35mm to guarantee the dimension necessity of the completed pipe.

three,Rotary feed mechanism
The rotary feeding mechanism is managed by servo motor or DC motor. The measurement of the rotation angle and the measurement of the feed by shifting the quantity of motor rotation to accomplish stepless adjustment. The rotary feeding mechanism is geared up with a feeding motor and a rotary motor. The tube blank is intermittently fed and rotated through a gear reduction mechanism respectively.

four,Middle part
The center mattress is created up of mattress, tube blank, carriage, bearing seat, screw Rod, basic lubricating gadget and so on. The middle bed adopts the welding bed, and the welding elements are annealed. The device entire body is outfitted with double bearing housing to generate the guide pipe blank into the trolley pull rod bracket, polished rod and so on. The two driving screws are fixed in the front and back again bearing seats, one stop of which is linked with a hexagonal coupling and a rotary feeding box, and the intermittent feeding of the pipe is recognized by the screw nut installed in the pipe billet feeding trolley, screw Rod Material: Special Screw Rod Materials YF45MnV. The bracket supports the screw Rod, the core rod and the tube blank. In the process of Tube Rolling, the tube blank is fed into the tube blank intermittently at the back end of the tube blank. When the tube blank is fed into the tube blank, the tube blank into the roof sleeve have to be transformed to match the distinct technical specs of the tube blank. In the process of halting and charging, the billet can be moved into the trolley to control the quick progress and retreat and stop at any situation of the middle mattress. The straightforward lubrication unit for the screw Rod lubricates the screw rod irregularly to increase the provider lifestyle of the screw nut.

five,Foundation circumstance
The box human body utilizes the welding piece, the welding piece carries on the anneal processing and the leakage take a look at. In get to facilitate the cleansing of the box physique and avert the accumulation of filth, a diversion plate is additional on the reinforcing rib of the box entire body. The chassis is outfitted with a shut higher include, which is hassle-free for computerized procedure in design and can avoid the splash of approach lubricant and h2o spray out of the equipment and lessen sound. The main and passive teeth are lubricated by oil injection. Gear materials: big equipment ZG310-570. Pinion forgings 40CR. (other supplies and procedures can be utilized according to customer’s specifications) the connecting rod adopts 45 # , normalizing. The driving shaft and connecting Rod Pin are quenched and tempered with 40Cr. Rack substance: 45, tooth area quenching remedy. Equipment Foundation XIHU (WEST LAKE) DIS. RAIL: the Xihu (West Lake) Dis. rail adopts separate or integral framework, the material is HT300 casting. CZPTs are lubricated with grease.

six,Discharge system
The discharging device is composed of a completed item pulling device, an oil scraping gadget, a discharge raceway, a finished item material rack and an oil pan. The CZPT Manage System immediately calculates when the conclude of a finished tube is a certain distance from the finish of the tube to the limit position ahead of it is sent into the trolley, alerts are despatched to the motor of the reducer of the concluded merchandise pulling system, and the completed tube is swiftly pulled into the discharge raceway, when the whole completed tube is pulled out, the cylinder in the discharge raceway turns the completed tube into the finished substance rack. Oil Pan is utilized to accumulate the residual oil on the completed merchandise tube to safeguard the web site atmosphere.

7,Primary generate system
It is made up of Z4 DC motor, belt drive, hydraulic Disc brake and assist. The utility design is utilised for driving the working body of the chilly pipe rolling mill and making it reciprocating. The technique utilizes 3-phase silicon controlled rectifier, Z four collection DC motor to generate the trigonometric belt, which is transmitted to a pair of driving gears in the chassis by means of a big pulley. The driving gears are engaged with the crank gears, then by means of the crank and connecting rod travel the function rack for reciprocating motion. In buy to empower the rack to stop at a established place (the modest opening of the roller) , a hydraulic Disc brake is installed on the help and connected to the motor shaft. To facilitate belt tightening, the Z4 DC motor, belt push, and hydraulic Disc brake are mounted on a movable support.

eight,hydraulic equipment
The hydraulic technique comprises a hydraulic station oil pump, a fuel tank unit, a corresponding electromagnetic manage valve and a pipeline. CZPT Method through stress control valve, flow handle valve, solenoid valve to management the precision of each hydraulic cylinder to make certain the normal procedure of the entire rolling system. The hydraulic cylinder includes a main Rod Chuck Oil Cylinder (one medium and reduced stress) .

9,Process Lubrication Technique
The cooling pump is mounted on a different oil tank the oil is sent to the head by a shunting mechanism to offer procedure lubrication and cooling of the tube blank, as effectively as lubrication of the guideway, head slide and equipment rack in the body.

10,CZPTal Handle System
The main motor velocity manage program and the motor drive program controlled by PLC are composed of electrical manage cabinet and operation panel. The Manage Centre of the program is Plc.. The entire electrical manage technique primarily is made up of transmission control method, rotary feed handle method, auxiliary handle method and so on.

Be aware:Can Be based mostly on consumer needs, right after the discussion of the configuration of the chilly mill rations.
