SIECC has been in machine industry field for about 10 years, we produce and sell all kinds of NC/CNC press brake, 3 or 4 roller rolling machine, high quality shearing machine including swing beam and various rank guillotine shears, hydraulic press, lathe machine, milling machine etc. All machines are under CE certification and experienced in the market of European such as United Kingdom, Belgium, Romania, Hungary, Croatia and also all the other countries in the world.
We produce about 50 sets of rolling monthly. In this large production volume, therefore enable us to be a price-effective in manufactory cost level. We consist in financial flexible principle to collaborate with our partner for a better recovery cost after their investment.
We also provide client-oriented after-sale service with engineer available if needed. In any cases, our action is in rapid response, immediately action in both consultation or site guidance.
ü THE MAIN CHARACTER
1. All machine body is welded assembly by high quality steels from CHINA BAO STEEL ENTERPRISE. After welding procedure, the machine body will be milled to ensure the balance and precision.
2. Three roller pyramid location, upper roller make up and down movement
3. Easy for plate feeding and convenient for rolling
4. All roller has gone through hardened treatment with HRC 55
5. Capable for cone and profile bending roll.
6. Around trip wires for human security protection
7. Adopt electronic centralized control, easy in operation
8. Cheap in price and high quality standard long usage-life
The machine is composed by three symmetrical roller, the upper roller is in the central vertical position above two bottom rollers for vertical up and down movement, the bottom rollers get the conversion motion by the screw rod and screw nut worm drive. The up roller is engaged with the bottom gear by the output gear of the reducer. The machine is in a full total structure, The working part, the main transmission part are equipped in one bottom rigid welded base,be convenient for installation and commissioning.
n THE WORKING PARTS
The working part is composed by up roller euipment, bottom roller equipment, up roller press equipment, balance equipment, overturned part, machine body, and bottom base.
1.1 The up roller equipment
The up roller equipment is composed by up roller,Bearing Block,SF-2 composite bearing etc.
1.2 The bottom Roller Equipment
The bottom roller equipment is composed by bottom roller,bottom roller input gear, SF-2 composite bearing etc.
1.3 The up roller press equipment
The up roller press equipment is composed by main motor,reducer,the worm gear structure, screw lifting mechanism etc.
1.4 The balance equipment
The balance equipment is composed by abutment,screw,adjustment nut etc.
1.5 1-7 Overturned part
Overturned part is composed by inverted frame,hand shank etc.
1.6 Machine body and bottom base
The machine is welded body, the based is weld assembly through annealing stress.
n THE MAIN TRANSMISSION PART
The main transmission part is composed by main motor, main reducer, a union joint, output gear etc.
n THE ELECTRICAL CONTROL PARTS
The electrical control part is composed by control cabinet, stroke control device etc.
ü WORKING PRINCIPLE
The is 3 roller pyramid symmetrical style, the upper roller makes up-down movement in the middle of the two bottom rollers through screw worm drive, and the output gear of the reducer connect the gear of the bottom rollers to get the torsion of the rolling process.
Upper roller revolve through O1 make rotary movement. Bottom side rollers revolve through O2 and O3 to make clockwise or anti-clockwise movement. The Upper roller can make also up-down movement.
The main driver are two bottom side rollers, it is drive by the main motor, clutch, reducer and open gear. Upper roller is drive by the friction between the roller and the plate and also make press function.
When working, the screw nun inside the worm gear will make rotary movement to make the guide screw and the bearing set of the upper roller to make up-down movement. The two bottom side rollers can make rotary in two direction and through the pressure of the upper roller ,the plate will be shaped into position.
