The four-roller plate bending machine has the function of correcting and clamping the plate, and the plate will not slide or deviate. It has the functions of overload prevention and hydraulic protection. The plate is fast, efficient and easy to operate.
Plate bending machine manufacturers take you to know the outstanding advantages of four roller plate bending machine:
It can pre-bend the plate end of the metal plate, and the remaining straight edge is small, and it does not need to use additional equipment such as a press to pre-bend, which has good process adaptability and high work efficiency.
Compared with the symmetrical three-roll bending machine, it can directly pre-bend the end of the plate without other equipment, and the remaining straight edge is small. This not only improves the quality of the workpiece, but also has simple process and convenient operation. The plate bending machine manufacturer tells you that the four-roller plate shearing machine adopts hydraulic transmission, which is lower than mechanical transmission, with low noise, high work efficiency, low energy consumption, compact structure, and convenient maintenance and use. It is suitable for heavy-duty workpiece rolling and occasions with high automation level and technical level.
The bending machine manufacturer takes you to know the equipment structure of the four-roller bending machine:
The four-roller bending machine is generally composed of an upper roller device, a lower roller device, a side roller device, a frame part, a tipping device, a balancing device, etc. The frame body part is the carrier of other parts, which is mainly composed of high and low frame and connecting frame on both sides. The frame body adopts Q235A steel plate welding structure, and the steel plate is subjected to shot peening pretreatment before welding, and annealing treatment after welding to eliminate internal stress, and the weld quality is strictly required. High and short frame using finite element analysis method, the computer-aided optimization design, the use of the overall welding structure of the frame has good strength and rigidity, precision retention to meet the strength and stiffness requirements of the plate rolling machine.
The position of the upper roller is fixed, both ends of which are equipped with bearing bodies, one end is installed in the high frame, and the other end is connected with the overturning bearing body (inverted head) hinged on the low frame. The overturning side of the upper roller is equipped with an overturning device, and the tail of the upper roller is equipped with a balancing mechanism. After dumping on the side of the dumping device, the balance upper roller is in a horizontal position, which is convenient for taking materials.
The lower roller bearing seat slide guide rail is processed on the high and low frames. The lower roller is lifted and lowered by two oil cylinders to push the lower roller up and down to clamp the plate. Both sides of the high and low frame are processed with side roller bearing seat slideway guide rails, and the side roller lifting oil cylinder provides power to raise or lower the side roller as the pressure for pre-bending or rolling of the plate.
The overturning device is equipped with an overturning oil cylinder, which can be overturned and erected. The overturning of the overturning device is convenient for the products to be taken out along the axial direction of the roller. The main drive of the equipment is hydraulic drive, which is directly coupled with the working roller drive by the hydraulic transmission device (including planetary reducer, brake, hydraulic motor, balance valve, overload valve, etc.) as the power of the plate bending machine.
JSP sliding bearings (metal ZCuZn24Al6Fe4Mn3-based embedded solid self-lubricating bearings) are used at the bearing seat and the sliding guide rail of the frame. The sliding bearing does not need to be oiled during the lifetime use of the equipment, so as to avoid equipment wear in the unlubricated state.
The four-roller plate bending machine has the function of correcting and clamping the plate, and the plate will not slide or deviate. It has the functions of overload prevention and hydraulic protection. The plate is fast, efficient and easy to operate.
