Structure and traits of gear:
1,Feeding device
The feeding device is composed of a feeding system, a feeding raceway, a chain wheel transmission system and a pipe jacking. Following the main rod clamping a few claws open, the starting button, the motor by means of the sprocket transmission system, driving the pipe jacking cart CZPT, by the pipe jacking mounted in front of the pipe jacking cart to send the billet into the mattress prior to the cart, commencing the sprocket generate in the opposite direction to exit the pipe jacking, clamping the core rod with the main rod and clamping the a few claws, commencing the mill to carry out the rolling, at the identical time pushing the pipe back again to the back restrict, via the cylinder pulling the material pulling system to change the billet pipe to the material feeding raceway, the pipe jacking truck slowly and gradually provides the pipe blank to the front restrict position and waits for the subsequent feeding.
two,Core Bar Chuck Assembly
The main bar chuck adopts hydraulic force type. The loosening and clamping of the core rod are achieved by the hydraulic cylinder. The axial adjustable stroke of the main bar chuck is ± 35mm to make certain the dimension prerequisite of the finished pipe.

3,Rotary feed mechanism
The rotary feeding mechanism is controlled by servo motor or DC motor. The measurement of the rotation angle and the dimension of the feed by shifting the amount of motor rotation to achieve 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 system respectively.

four,Centre component
The center bed is produced up of bed, tube blank, carriage, bearing seat, screw Rod, easy lubricating unit and so on. The center bed adopts the welding bed, and the welding parts are annealed. The equipment human body is outfitted with double bearing housing to travel the guide pipe blank into the trolley pull rod bracket, polished rod and so on. The two driving screws are fastened in the entrance and again bearing seats, one end 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 Substance: Special Screw Rod Material YF45MnV. The bracket supports the screw Rod, the main rod and the tube blank. In the procedure of Tube Rolling, the tube blank is fed into the tube blank intermittently at the again stop 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 go well with the distinct specs of the tube blank. In the process of halting and charging, the billet can be moved into the trolley to control the quick advance and retreat and end at any situation of the middle bed. The easy lubrication device for the screw Rod lubricates the screw rod irregularly to improve the service daily life of the screw nut.

5,Base scenario
The box body uses the welding piece, the welding piece carries on the anneal processing and the leakage examination. In purchase to aid the cleaning of the box human body and avert the accumulation of grime, a diversion plate is added on the reinforcing rib of the box human body. The chassis is outfitted with a shut upper cover, which is practical for automatic operation in design and style and can prevent the splash of approach lubricant and water spray out of the machine and decrease sound. The major and passive enamel are lubricated by oil injection. Equipment materials: huge equipment ZG310-570. Pinion forgings 40CR. (other resources and procedures can be used according to customer’s requirements) 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 treatment method. Device Base XIHU (WEST LAKE) DIS. RAIL: the Xihu (West Lake) Dis. rail adopts different or integral construction, the substance is HT300 casting. CZPTs are lubricated with grease.

6,Discharge program
The discharging system is composed of v-shaped groove and discharging platform. The v-formed trough and the discharge system are each and every a welded body. The discharge length can be developed in accordance to the user’s needs. An oil pan is arranged beneath the discharge system to resolve possible residual liquid in the pipe.

7,Major generate system
Adopt energy-consuming braking manner. It is mostly composed of Z4 type DC motor, belt driving system, assistance and so on. The massive belt pulley is driven by a DC motor via a slim v-joint belt on a little belt pulley. The little belt pulley and the main motor are fastened on a foundation with an adjustable screw to modify the tightness of the belt. Massive Belt pulley by means of static stability check, to guarantee the smooth procedure.

eight,hydraulic equipment
The hydraulic technique comprises a hydraulic station oil pump, a gasoline tank unit, a corresponding electromagnetic control valve and a pipeline. CZPT Program by means of strain management valve, stream management valve, solenoid valve to control the precision of every single hydraulic cylinder to make sure the regular operation of the whole rolling method. The hydraulic cylinder includes a main Rod Chuck Oil Cylinder (one medium and lower pressure) .

nine,Procedure Lubrication System
The cooling pump is mounted on a individual oil tank the oil is sent to the head by a shunting mechanism to provide 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 Handle System
The primary motor pace control system and the motor generate technique managed by PLC are composed of electric powered handle cupboard and operation panel. The Handle Center of the technique is Plc.. The entire electrical management system mostly is made up of transmission manage technique, rotary feed manage program, auxiliary manage system and so on.

Be aware:Can Be primarily based on buyer needs, following the discussion of the configuration of the chilly mill rations.
