Structure and traits of products:
one,Feeding system
The feeding system is composed of a feeding system, a feeding raceway, a chain wheel transmission unit and a pipe jacking. Following the main rod is clamped and the three jaws are opened, the frequency conversion motor is activated by way of the sprocket travel to drive the pipe jacking trolley CZPT, and the pipe jacking in entrance of the pipe jacking trolley sends the billet into the lathe bed just before the trolley, reverse start sprocket transmission gadget out of the pipe, core rod clamping a few claw clamping main Rod, rolling mill start, at the very same time again to the again restrict pipe, through the cylinder pull pull pull pull pull pull the billet tube to the feeding roller, the pipe jacking truck rapidly sends the pipe blank to the entrance limit and waits for the up coming feeding. By way of the encoder looking through guiding the sprocket shaft, the size of every tube blank is calculated, so that the bed is despatched into the trolley for the tube blank quickly rear-end collision.
two,Main Bar Chuck Assembly
The core bar chuck adopts hydraulic strain kind. The loosening and clamping of the main rod are achieved by the hydraulic cylinder. The axial adjustable stroke of the main bar chuck is ± 35mm to make certain the dimension need of the completed pipe.

3,Rotary feed mechanism
The rotary feeding system is managed by servo motor or DC motor. The dimension of the rotation angle and the dimension of the feed by changing the amount 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 gear reduction mechanism respectively.

4,Centre element
The middle mattress is created up of mattress, tube blank, carriage, bearing seat, screw Rod, straightforward lubricating system and so on. The middle mattress adopts the welding bed, and the welding areas are annealed. The equipment body is outfitted with double bearing housing to travel the direct pipe blank into the trolley pull rod bracket, polished rod and so on. The two driving screws are fastened in the entrance and back again bearing seats, one particular conclude of which is related 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 Substance YF45MnV. The bracket supports the screw Rod, the main rod and the tube blank. In the method 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 must be transformed to fit the distinct specifications of the tube blank. In the approach of stopping and charging, the billet can be moved into the trolley to handle the rapid progress and retreat and quit at any place of the middle mattress. The simple lubrication gadget for the screw Rod lubricates the screw rod irregularly to increase the service life of the screw nut.

5,Foundation scenario
The box human body uses the welding piece, the welding piece carries on the anneal processing and the leakage examination. In order to facilitate the cleaning of the box entire body and prevent the accumulation of grime, a diversion plate is included on the reinforcing rib of the box body. The chassis is equipped with a shut higher include, which is hassle-free for automatic procedure in design and style and can avoid the splash of method lubricant and drinking water spray out of the device and lessen sounds. The major and passive tooth are lubricated by oil injection. Equipment substance: large gear ZG310-570. Pinion forgings 40CR. (other supplies and procedures can be utilised according to customer’s needs) the connecting rod adopts forty five # , normalizing. The driving shaft and connecting Rod Pin are quenched and tempered with 40Cr. Rack materials: forty five, tooth surface area quenching treatment. Equipment Base XIHU (WEST LAKE) DIS. RAIL: the Xihu (West Lake) Dis. rail adopts independent or integral composition, the content is HT300 casting. CZPTs are lubricated with grease.
  

six,Discharge system
The discharging gadget is composed of a completed product pulling gadget, an oil scraping device, a discharge raceway, a finished solution substance rack and an oil pan. The CZPT Handle Method instantly calculates when the conclude of a completed tube is a certain distance from the end of the tube to the restrict placement before it is sent into the trolley, signals are sent to the motor of the reducer of the concluded merchandise pulling system, and the concluded tube is speedily pulled into the discharge raceway, when the entire concluded tube is pulled out, the cylinder in the discharge raceway turns the concluded tube into the completed material rack. Oil Pan is employed to acquire the residual oil on the finished product tube to protect the site setting.

seven,Major push mechanism
It is composed of Z4 DC motor, belt push, hydraulic Disc brake and assist. The utility model is utilized for driving the functioning frame of the cold pipe rolling mill and creating it reciprocating. The technique utilizes three-period silicon managed rectifier, Z four sequence DC motor to push 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 through the crank and connecting rod travel the work rack for reciprocating motion. In order to permit the rack to stop at a set place (the tiny opening of the roller) , a hydraulic Disc brake is set up on the assistance and related to the motor shaft. To aid belt tightening, the Z4 DC motor, belt travel, and hydraulic Disc brake are mounted on a movable assistance.

eight,hydraulic machinery
The hydraulic method includes a hydraulic station oil pump, a fuel tank gadget, a corresponding electromagnetic manage valve and a pipeline. CZPT Program by means of force management valve, flow control valve, solenoid valve to control the accuracy of each and every hydraulic cylinder to ensure the normal procedure of the total rolling method. The hydraulic cylinder contains a core Rod Chuck Oil Cylinder (one medium and minimal strain) .

9,Method Lubrication Program
The cooling pump is mounted on a individual oil tank the oil is sent to the head by a shunting mechanism to give procedure lubrication and cooling of the tube blank, as well as lubrication of the guideway, head slide and equipment rack in the body.

10,CZPTal Control Program
The primary motor speed control method and the motor travel system controlled by PLC are composed of electric powered control cabinet and operation panel. The Handle Center of the method is Plc.. The whole electrical manage method primarily is made up of transmission handle method, rotary feed control program, auxiliary handle program and so on.

Note:Can Be primarily based on consumer needs, following the discussion of the configuration of the cold mill rations.
