Composition and characteristics of tools:
1,Feeding device
The feeding gadget is composed of a feeding system, a feeding raceway, a chain wheel transmission gadget and a pipe jacking. Right after the main rod clamping a few claws open, the starting up button, the motor by means of the sprocket transmission gadget, driving the pipe jacking cart CZPT, by the pipe jacking mounted in entrance of the pipe jacking cart to deliver the billet into the mattress just before the cart, starting the sprocket travel in the opposite course to exit the pipe jacking, clamping the main rod with the core rod and clamping the 3 claws, beginning the mill to carry out the rolling, at the very same time pushing the pipe back again to the back again limit, by way of the cylinder pulling the substance pulling system to change the billet pipe to the materials feeding raceway, the pipe jacking truck little by little provides the pipe blank to the entrance limit placement and waits for the next feeding.
two,Core Bar Chuck Assembly
The main bar chuck adopts hydraulic pressure kind. The loosening and clamping of the main rod are attained by the hydraulic cylinder. The axial adjustable stroke of the main bar chuck is ± 35mm to make certain the dimension prerequisite of the concluded pipe.

3,Rotary feed system
The rotary feeding mechanism is controlled by servo motor or DC motor. The size of the rotation angle and the dimensions of the feed by shifting the quantity of motor rotation to obtain 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 via a equipment reduction system respectively.

4,Centre part
The middle mattress is produced up of mattress, tube blank, carriage, bearing seat, screw Rod, straightforward lubricating device and so on. The middle mattress adopts the welding bed, and the welding elements are annealed. The machine physique is equipped with double bearing housing to drive 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, a single stop of which is related with a hexagonal coupling and a rotary feeding box, and the intermittent feeding of the pipe is understood by the screw nut installed in the pipe billet feeding trolley, screw Rod Content: Unique Screw Rod Content YF45MnV. The bracket supports the screw Rod, the main rod and the tube blank. In the process of Tube Rolling, the tube blank is fed into the tube blank intermittently at the back again conclude of the tube blank. When the tube blank is fed into the tube blank, the tube blank into the roof sleeve should be altered to go well with the distinct specifications of the tube blank. In the process of halting and charging, the billet can be moved into the trolley to control the rapid progress and retreat and end at any situation of the center bed. The basic lubrication system for the screw Rod lubricates the screw rod irregularly to boost the service lifestyle of the screw nut.

5,Foundation case
The box entire body uses the welding piece, the welding piece carries on the anneal processing and the leakage check. In buy to aid the cleaning of the box body and avoid the accumulation of grime, a diversion plate is included on the reinforcing rib of the box entire body. The chassis is equipped with a closed upper include, which is practical for automated operation in style and can avoid the splash of approach lubricant and water spray out of the machine and lessen sound. The main and passive tooth are lubricated by oil injection. Gear material: huge equipment ZG310-570. Pinion forgings 40CR. (other supplies and procedures can be utilized in accordance to customer’s specifications) the connecting rod adopts forty five # , normalizing. The driving shaft and connecting Rod Pin are quenched and tempered with 40Cr. Rack substance: forty five, tooth surface quenching treatment method. Equipment Base XIHU (WEST LAKE) DIS. RAIL: the Xihu (West Lake) Dis. rail adopts different or integral framework, the content is HT300 casting. CZPTs are lubricated with grease.

6,Discharge method
The discharging method is composed of v-formed groove and discharging platform. The v-shaped trough and the discharge platform are every a welded body. The discharge length can be designed according to the user’s needs. An oil pan is arranged below the discharge platform to resolve achievable residual liquid in the pipe.

7,Major push mechanism
It consists of Z4 DC motor, belt generate, hydraulic Disc brake and help. The utility model is utilised for driving the operating body of the chilly pipe rolling mill and making it reciprocating. The system makes use of 3-phase silicon controlled rectifier, Z four collection DC motor to travel the trigonometric belt, which is transmitted to a pair of driving gears in the chassis by way of a massive pulley. The driving gears are engaged with the crank gears, then by means of the crank and connecting rod drive the work rack for reciprocating movement. In order to permit the rack to stop at a established placement (the little opening of the roller) , a hydraulic Disc brake is put in on the assistance and linked to the motor shaft. To facilitate belt tightening, the Z4 DC motor, belt travel, and hydraulic Disc brake are mounted on a movable help.

eight,hydraulic machinery
The hydraulic system includes a hydraulic station oil pump, a fuel tank unit, a corresponding electromagnetic management valve and a pipeline. CZPT Technique via force control valve, circulation handle valve, solenoid valve to handle the precision of each hydraulic cylinder to guarantee the normal procedure of the complete rolling technique. The hydraulic cylinder comprises a main Rod Chuck Oil Cylinder (1 medium and minimal force) .

9,Procedure Lubrication System
The cooling pump is mounted on a separate oil tank the oil is delivered to the head by a shunting mechanism to offer procedure lubrication and cooling of the tube blank, as nicely as lubrication of the guideway, head slide and equipment rack in the body.

ten,CZPTal Management Program
The major motor pace manage system and the motor drive system managed by PLC are composed of electrical management cupboard and operation panel. The Handle Center of the method is Plc.. The total electrical control method mostly consists of transmission manage method, rotary feed handle technique, auxiliary manage program and so on.

Observe:Can Be primarily based on customer demands, right after the discussion of the configuration of the cold mill rations.
