Construction and characteristics of equipment:
1,Feeding gadget
The feeding system is composed of a feeding platform, a feeding raceway, a chain wheel transmission system and a pipe jacking. Following the core rod is clamped and the a few jaws are opened, the frequency conversion motor is activated via the sprocket drive to travel the pipe jacking trolley CZPT, and the pipe jacking in front of the pipe jacking trolley sends the billet into the lathe mattress prior to the trolley, reverse commence sprocket transmission unit out of the pipe, main rod clamping 3 claw clamping core Rod, rolling mill start, at the same time back again to the back limit pipe, via 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 front limit and waits for the following feeding. By way of the encoder looking through powering the sprocket shaft, the size of each tube blank is measured, so that the mattress is sent into the trolley for the tube blank quick rear-end collision.

2,Core Bar Chuck Assembly
The core bar chuck adopts hydraulic force sort. The loosening and clamping of the core rod are completed by the hydraulic cylinder. The axial adjustable stroke of the core bar chuck is ± 35mm to make sure the dimension necessity of the completed pipe.

three,Rotary feed system
The rotary feeding system is controlled by servo motor or DC motor. The dimensions of the rotation angle and the dimensions of the feed by changing the quantity of motor rotation to obtain stepless adjustment. The rotary feeding system is geared up with a feeding motor and a rotary motor. The tube blank is intermittently fed and rotated by means of a equipment reduction mechanism respectively.

four,Centre element
The center mattress is made up of bed, tube blank, carriage, bearing seat, screw Rod, straightforward lubricating system and so on. The middle bed adopts the welding mattress, and the welding components are annealed. The device human body is outfitted with double bearing housing to generate the direct pipe blank into the trolley pull rod bracket, polished rod and so on. The two driving screws are set in the entrance and again bearing seats, a single stop of which is connected with a hexagonal coupling and a rotary feeding box, and the intermittent feeding of the pipe is recognized by the screw nut mounted in the pipe billet feeding trolley, screw Rod Content: Special Screw Rod Content YF45MnV. The bracket supports the screw Rod, the main rod and the tube blank. In the approach of Tube Rolling, the tube blank is fed into the tube blank intermittently at the back again finish of the tube blank. When the tube blank is fed into the tube blank, the tube blank into the roof sleeve should be changed to fit the various technical specs of the tube blank. In the process of halting and charging, the billet can be moved into the trolley to control the fast advance and retreat and stop at any place of the center bed. The straightforward lubrication unit for the screw Rod lubricates the screw rod irregularly to boost the services lifestyle of the screw nut.

five,Foundation circumstance
The box human body uses the welding piece, the welding piece carries on the anneal processing and the leakage take a look at. In buy to facilitate the cleansing of the box entire body and avoid the accumulation of dirt, a diversion plate is included on the reinforcing rib of the box entire body. The chassis is outfitted with a shut upper include, which is handy for automated operation in design and style and can avert the splash of method lubricant and drinking water spray out of the device and reduce sound. The major and passive enamel are lubricated by oil injection. Gear material: huge equipment ZG310-570. Pinion forgings 40CR. (other components and procedures can be utilized in accordance 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 floor quenching remedy. Equipment Foundation XIHU (WEST LAKE) DIS. RAIL: the Xihu (West Lake) Dis. rail adopts different or integral composition, the substance is HT300 casting. CZPTs are lubricated with grease.

six,Discharge system
The discharging system is composed of a concluded product pulling system, an oil scraping system, a discharge raceway, a finished item substance rack and an oil pan. The CZPT Control Technique immediately calculates when the finish of a concluded tube is a specified distance from the finish of the tube to the limit place before it is despatched into the trolley, indicators are despatched to the motor of the reducer of the completed merchandise pulling unit, and the concluded tube is quickly pulled into the discharge raceway, when the total completed tube is pulled out, the cylinder in the discharge raceway turns the finished tube into the completed materials rack. Oil Pan is used to collect the residual oil on the concluded item tube to protect the site surroundings.

seven,Major drive mechanism
It is made up of Z4 DC motor, belt travel, hydraulic Disc brake and help. The utility model is utilized for driving the doing work body of the chilly pipe rolling mill and generating it reciprocating. The method uses three-stage silicon managed rectifier, Z 4 sequence DC motor to generate the trigonometric belt, which is transmitted to a pair of driving gears in the chassis by way of a large pulley. The driving gears are engaged with the crank gears, then by means of the crank and connecting rod travel the work rack for reciprocating movement. In get to allow the rack to cease at a set position (the small opening of the roller) , a hydraulic Disc brake is mounted on the assistance and connected to the motor shaft. To aid belt tightening, the Z4 DC motor, belt push, and hydraulic Disc brake are mounted on a movable help.

8,hydraulic equipment
The hydraulic technique includes a hydraulic station oil pump, a gas tank unit, a corresponding electromagnetic control valve and a pipeline. CZPT Method by way of force control valve, circulation handle valve, solenoid valve to control the precision of each hydraulic cylinder to guarantee the normal procedure of the total rolling system. The hydraulic cylinder comprises a core Rod Chuck Oil Cylinder (1 medium and reduced force) .

9,Process Lubrication Technique
The cooling pump is mounted on a independent oil tank the oil is sent to the head by a shunting mechanism to provide approach 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 System
The major motor velocity handle program and the motor travel technique managed by PLC are composed of electrical control cupboard and procedure panel. The Control Middle of the technique is Plc.. The entire electrical handle system largely is made up of transmission control program, rotary feed management method, auxiliary control system and so on.

Notice:Can Be based on buyer wants, after the discussion of the configuration of the cold mill rations.
