Composition and characteristics of products:
one,Feeding unit
The feeding device is composed of a feeding system, a feeding raceway, a chain wheel transmission system and a pipe jacking. After the main rod clamping three claws open, the starting up button, the motor through the sprocket transmission gadget, driving the pipe jacking cart CZPT, by the pipe jacking put in in entrance of the pipe jacking cart to send out the billet into the mattress just before the cart, commencing the sprocket generate in the reverse path to exit the pipe jacking, clamping the main rod with the core rod and clamping the 3 claws, starting up the mill to have out the rolling, at the identical time pushing the pipe again to the back restrict, through the cylinder pulling the content pulling mechanism to change the billet pipe to the content feeding raceway, the pipe jacking truck little by little provides the pipe blank to the front restrict placement and waits for the next feeding.
two,Main Bar Chuck Assembly
The core bar chuck adopts hydraulic strain form. The loosening and clamping of the main rod are completed by the hydraulic cylinder. The axial adjustable stroke of the main bar chuck is ± 35mm to make sure the dimension prerequisite of the concluded pipe.

three,Rotary feed mechanism
The rotary feeding mechanism is controlled by servo motor or DC motor. The measurement of the rotation angle and the dimensions of the feed by modifying the number of motor rotation to attain stepless adjustment. The rotary feeding mechanism is equipped with a feeding motor and a rotary motor. The tube blank is intermittently fed and rotated by way of a gear reduction system respectively.

four,Heart element
The middle bed is made up of mattress, tube blank, carriage, bearing seat, screw Rod, simple lubricating device and so on. The center bed adopts the welding bed, and the welding elements are annealed. The equipment entire body is equipped with double bearing housing to drive the guide pipe blank into the trolley pull rod bracket, polished rod and so on. The two driving screws are mounted in the front and back bearing seats, one particular conclude of which is linked with a hexagonal coupling and a rotary feeding box, and the intermittent feeding of the pipe is realized by the screw nut set up in the pipe billet feeding trolley, screw Rod Content: Particular Screw Rod Materials 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 conclude of the tube blank. When the tube blank is fed into the tube blank, the tube blank into the roof sleeve should be transformed to match the diverse specs of the tube blank. In the process of halting and charging, the billet can be moved into the trolley to control the speedy advance and retreat and quit at any position of the center bed. The straightforward lubrication system for the screw Rod lubricates the screw rod irregularly to boost the support lifestyle of the screw nut.

five,Base situation
The box human body utilizes the welding piece, the welding piece carries on the anneal processing and the leakage examination. In get to facilitate the cleansing of the box physique and avoid the accumulation of grime, a diversion plate is added on the reinforcing rib of the box physique. The chassis is equipped with a shut higher cover, which is handy for automatic operation in design and can avert the splash of method lubricant and drinking water spray out of the machine and reduce noise. The principal and passive teeth are lubricated by oil injection. Equipment substance: huge gear ZG310-570. Pinion forgings 40CR. (other materials and processes can be utilized in accordance to customer’s requirements) the connecting rod adopts forty five # , normalizing. The driving shaft and connecting Rod Pin are quenched and tempered with 40Cr. Rack materials: 45, tooth floor quenching therapy. Equipment Base XIHU (WEST LAKE) DIS. RAIL: the Xihu (West Lake) Dis. rail adopts individual or integral structure, the material is HT300 casting. CZPTs are lubricated with grease.
  

6,Discharge method
The discharging technique is composed of v-formed groove and discharging system. The v-shaped trough and the discharge platform are each and every a welded entire body. The discharge length can be designed in accordance to the user’s requirements. An oil pan is arranged under the discharge system to solve possible residual liquid in the pipe.

7,Primary generate system
It consists of Z4 DC motor, belt generate, hydraulic Disc brake and help. The utility product is utilised for driving the doing work body of the chilly pipe rolling mill and creating it reciprocating. The technique employs 3-section silicon controlled rectifier, Z four sequence DC motor to travel the trigonometric belt, which is transmitted to a pair of driving gears in the chassis via a big pulley. The driving gears are engaged with the crank gears, then via the crank and connecting rod push the function rack for reciprocating motion. In order to enable the rack to end at a set placement (the tiny opening of the roller) , a hydraulic Disc brake is set up on the assist and related to the motor shaft. To facilitate belt tightening, the Z4 DC motor, belt push, and hydraulic Disc brake are mounted on a movable assistance.

8,hydraulic machinery
The hydraulic technique contains a hydraulic station oil pump, a gas tank unit, a corresponding electromagnetic handle valve and a pipeline. CZPT Technique by way of pressure management valve, flow control valve, solenoid valve to manage the accuracy of every hydraulic cylinder to guarantee the regular operation of the complete rolling technique. The hydraulic cylinder comprises a main Rod Chuck Oil Cylinder (1 medium and reduced strain) .

nine,Method Lubrication Program
The cooling pump is mounted on a individual oil tank the oil is delivered to the head by a shunting system to provide process lubrication and cooling of the tube blank, as properly as lubrication of the guideway, head slide and gear rack in the body.

ten,CZPTal Control Technique
The primary motor velocity management system and the motor push program controlled by PLC are composed of electric powered handle cupboard and procedure panel. The Manage Middle of the technique is Plc.. The entire electrical control program primarily is composed of transmission manage program, rotary feed handle program, auxiliary management technique and so on.

Notice:Can Be primarily based on customer wants, following the discussion of the configuration of the cold mill rations.
