Framework and attributes of products:
The feeding gadget is composed of a feeding platform, a feeding raceway, a chain wheel transmission system and a pipe jacking. Soon after the core rod clamping 3 claws open, the starting button, the motor through the sprocket transmission device, driving the pipe jacking cart CZPT, by the pipe jacking set up in front of the pipe jacking cart to ship the billet into the mattress ahead of the cart, starting up the sprocket drive in the opposite route to exit the pipe jacking, clamping the main rod with the main rod and clamping the three claws, starting the mill to carry out the rolling, at the same time pushing the pipe again to the back limit, by way of the cylinder pulling the material pulling system to shift the billet pipe to the substance feeding raceway, the pipe jacking truck slowly delivers the pipe blank to the front restrict place and waits for the up coming feeding.
two,Main Bar Chuck Assembly
The main bar chuck adopts hydraulic pressure form. The loosening and clamping of the main rod are completed by the hydraulic cylinder. The axial adjustable stroke of the core bar chuck is ± 35mm to guarantee the dimension need of the concluded pipe.
three,Rotary feed mechanism
The rotary feeding mechanism is controlled by servo motor or DC motor. The dimension of the rotation angle and the dimension of the feed by modifying the amount of motor rotation to attain 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.
The middle mattress is manufactured up of bed, tube blank, carriage, bearing seat, screw Rod, basic lubricating device and so on. The middle bed adopts the welding bed, and the welding elements are annealed. The device body is outfitted with double bearing housing to generate 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 back bearing seats, one finish 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 Substance: Specific Screw Rod Substance YF45MnV. The bracket supports the screw Rod, the core rod and the tube blank. In the approach of Tube Rolling, the tube blank is fed into the tube blank intermittently at the back finish of the tube blank. When the tube blank is fed into the tube blank, the tube blank into the roof sleeve must be modified to suit the diverse specifications of the tube blank. In the procedure of stopping and charging, the billet can be moved into the trolley to handle the quick progress and retreat and quit at any place of the center bed. The easy lubrication unit for the screw Rod lubricates the screw rod irregularly to enhance the support life of the screw nut.
The box body uses the welding piece, the welding piece carries on the anneal processing and the leakage check. In buy to facilitate the cleaning of the box human body and prevent the accumulation of grime, a diversion plate is included on the reinforcing rib of the box body. The chassis is outfitted with a closed upper cover, which is hassle-free for computerized operation in style and can prevent the splash of approach lubricant and h2o spray out of the machine and lessen noise. The primary and passive tooth are lubricated by oil injection. Gear content: huge equipment ZG310-570. Pinion forgings 40CR. (other supplies and processes can be employed in accordance to customer’s requirements) the connecting rod adopts 45 # , normalizing. The driving shaft and connecting Rod Pin are quenched and tempered with 40Cr. Rack content: 45, tooth area quenching treatment method. Equipment Base XIHU (WEST LAKE) DIS. RAIL: the Xihu (West Lake) Dis. rail adopts different or integral construction, the material is HT300 casting. CZPTs are lubricated with grease.
The discharging technique is composed of v-formed groove and discharging platform. The v-formed trough and the discharge platform are each a welded body. The discharge duration can be made in accordance to the user’s specifications. An oil pan is arranged underneath the discharge system to remedy feasible residual liquid in the pipe.
seven,Principal push mechanism
It consists of Z4 DC motor, belt drive, hydraulic Disc brake and assist. The utility product is utilised for driving the doing work body of the chilly pipe rolling mill and creating it reciprocating. The system utilizes 3-stage silicon managed rectifier, Z four collection DC motor to generate the trigonometric belt, which is transmitted to a pair of driving gears in the chassis through a large pulley. The driving gears are engaged with the crank gears, then through the crank and connecting rod travel the perform rack for reciprocating motion. In get to permit the rack to stop at a set position (the modest opening of the roller) , a hydraulic Disc brake is installed on the support and linked to the motor shaft. To aid belt tightening, the Z4 DC motor, belt generate, and hydraulic Disc brake are mounted on a movable support.
The hydraulic program contains a hydraulic station oil pump, a gas tank device, a corresponding electromagnetic control valve and a pipeline. CZPT System by way of strain handle valve, stream handle valve, solenoid valve to handle the precision of every hydraulic cylinder to make certain the regular operation of the total rolling technique. The hydraulic cylinder comprises a core Rod Chuck Oil Cylinder (one medium and low pressure) .
nine,Process Lubrication Method
The cooling pump is mounted on a separate oil tank the oil is shipped to the head by a shunting mechanism to provide process lubrication and cooling of the tube blank, as effectively as lubrication of the guideway, head slide and gear rack in the body.
10,CZPTal Manage Technique
The primary motor pace control method and the motor drive program controlled by PLC are composed of electrical manage cupboard and procedure panel. The Control Centre of the technique is Plc.. The complete electrical handle method mostly is composed of transmission handle program, rotary feed control method, auxiliary handle program and so on.
Observe:Can Be based on customer wants, following the dialogue of the configuration of the chilly mill rations.
