According to the mechanical structure and the number of coils of the plate rolling machine, it is divided into three-roller rolling machine and four-roller plate rolling machine. According to the driving mode of the roller, there are mechanical rolling machine and hydraulic rolling machine. The machine structure is relatively simple. Among the three rollers, there are a pair of side rollers and a top roller, in which the upper roller can move up and down. The structure of the four-roller coiling machine is relatively complex. There are a pair of side rollers and an upper roller and a lower roller. The cost of the coiler is high, but the performance is good, and the quality of the finished product is better. The driving confluence coiling machine mainly includes the pouring device, the transmission portion, the upper roller, the lower roller, and the frame. Its structure is that the opinions of the plurality of transmission portions mesh with the large gears at the ends of the upper rollers, and the transmission portions are two groups. , And with the upper roll horizontally symmetrically arranged, the transmission part can also be three groups, and the above roller is arranged symmetrically with a center of 120°, the transmission part can also be four groups, and the above roller is arranged symmetrically with the center of the circle at 90°.
The working principle of all kinds of plate rolling machines is the same. By adjusting the relative positions of the upper roller and the side roller, the sheet material gradually bends and deforms between the rollers. The positive and negative rotation of the spindle causes the sheet material to move back and forth between the rollers until the sheet material. Plastic deformation occurs. With the constant adjustment of the relative position of the roller, the spindle constantly reciprocates forward and reverse movement, and the plastic deformation of the sheet material gradually increases until it is processed into a circular or round-shaped finished product that meets the requirements.
