Reference Picture and Product Description:
1, The up-roller device
The up-roller device consists of the main cylinder, roller bearing, roller, double row self-aligning bearings and other components. Two master cylinder to provide the required roll sheet the pressure, the master cylinder working pressure 19.5 MPa. Double row self-aligning bearing low-speed, heavy-duty self-aligning roller bearings.
The rollers are made of steel 42CrMo, quenching after roughing HB260 ~ 300, according to JB / ZG4289-86 roll steel standard, stiffness in line with (1/700 ~ 1/1000) L (L- refers rack centerline on both sides distance between). Surface coated, to ensure that the workpiece no scratches.
2, The low-roller and horizontal movement device
The low -roller consists of the low- roller, low- roller, bearing, the low- roller, input gear, the low- roller, bearing and other components.
The same material as the low roller 42CrMo, after roughing quenching HB240 ~ 280 according to JB / ZG4289-86 roll steel standard, stiffness in line with (1/700 ~ 1/1000) LL- refers to the distance between the center line on both sides of the rack. Surface coated, to ensure that the workpiece no scratches.
Selection of the low- roller bearing SF-2 self-lubricating composite material.
The level of mobile device provided by the horizontal movement motor power, through the worm box (worm uses ZQAl9-4), worm, screw nut mechanism driven by the horizontal movement of the roller assembly to achieve asymmetric rolled sheet.
Lower roller main drive is powered through the main transmission output gear, the next roll input gear, open drive torque to low- roller.
3, Supporting roller device
Supporting roller device consists of supporting roller worm mechanism, wedge mechanism and other components.
Roller made of 45 steel, quenched and tempered hardness HB190 ~ 220, surface coated, lower than the surface hardness of the roller surface hardness lower roller rollers.
A total of two groups of idlers four, according to the roll sheet specifications of the load size, be adjusted up and down.
4, The main gear
The main drive can be reversible, to provide roll torque roll sheet.
Main drive by the main motor, electro-hydraulic putt brake, spur gear reducer, output gear components.
5, Tipping device
Tipping device consists of ram tipping cylinders and other components.
Tipping cylinder piston rod chrome plated, produced by professional manufacturers (standard HSG).
Upset upset means to facilitate product removal roller axial direction.
6, Fixed, tipping side frame, chassis
Fixed, overturned side frame, welded steel chassis, stress relief annealing after welding, shot blasting.
Fixed, tipping side frame built to accommodate two master cylinders.
Chassis with frame structure, high torsional section modulus, less bolt, installation and easy commissioning.
