[0009] Preferably, the wall panel is provided with a slideway corresponding to the lateral clamping cylinder, and the telescopic rod of the lateral clamping cylinder passes through the slideway to connect to the male mold.

[0010] Preferably, there are two driven rolling wheels, which are symmetrically arranged front to back, and each driven rolling wheel corresponds to a driven oil cylinder one by one.

[0012] Preferably, the pressing cylinder, the lateral clamping cylinder and the slave cylinder are controlled by PLC.

[0013] The beneficial effects of the utility model are:

[0014] The lateral clamping cylinder drives the male die to clamp the workpiece to be rolled horizontally.

[0018] See also Figure 1 and Figure 2The utility model relates to a roller mill for rolling and processing crane wheels, comprising a base 1, a wall panel 2, a lifting platform 3, a pressing oil cylinder 4, a lateral clamping oil cylinder 5, a male die 6, an active roller 8, a driven roller 9 and a driven oil cylinder 10. The base 1 is connected to the lifting platform 3 through the wall panel 2, and two wall panels 2 are arranged on the left and right sides of the base 1. The lifting platform 3 is driven to rise and fall by the pressing oil cylinder 4. A lateral clamping oil cylinder 5 is fixedly provided on each wall panel 2. The telescopic rod of the lateral clamping oil cylinder 5 is connected to the male die 6, and the workpiece to be rolled 7 is clamped It is held between two male dies 6 so that the workpiece 7 to be rolled can maintain the horizontal profile section size unchanged during the rolling process. The lifting platform 3 is provided with a motor 11, a reducer 12 and an active rolling wheel 8. The motor 11 drives the reducer 12 to decelerate and then transmits the power to the active rolling wheel 8. The active rolling wheel 8 is correspondingly arranged above the workpiece 7 to be rolled. The base 1 is provided with a driven rolling wheel 9 with a driven cylinder 10 corresponding to the workpiece 7 to be rolled. The driven rolling wheel 9 is rotatably arranged on the telescopic rod of the driven cylinder 10, and the driven cylinder 10 is fixed on the base 1.

[0019] There are two downward pressing oil cylinders 4, and the two downward pressing oil cylinders 4 are respectively fixedly arranged on the wall panels 1 on the corresponding sides.

[0020] The wall panel 1 is provided with a slideway corresponding to the lateral clamping cylinder 5 , and the telescopic rod of the lateral clamping cylinder 5 passes through the slideway to connect the male mold 6 , and the male mold 6 matches the transverse special-shaped section of the workpiece 7 to be rolled.

[0021] The motor 11 and the reducer 12 are fixed on the top surface of the lifting platform 3, and the active roller 8 is rotatably arranged on the bottom surface of the lifting platform 3. The motor 11 is connected to the high-speed input shaft of the reducer 12, and the low-speed output shaft of the reducer 12 is connected to the active roller 8.

[0022] There are two driven rolling wheels 9 , which are symmetrically arranged front and back. The two driven rolling wheels 9 and the driving rolling wheel 8 are distributed in a regular triangle and act together on the annular surface of the workpiece 7 to be rolled.

[0024] The pressing cylinder 4, the lateral clamping cylinder 5 and the driven cylinder 10 are controlled by PLC. When the manipulator clamps the workpiece 7 to be rolled and puts it into the roller mill, the roller mill receives a signal (a photoelectric sensor or other method can be used, or the manipulator gives an upper signal), and the lateral clamping cylinders 5 on both sides are activated to clamp the workpiece 7 to be rolled. After reaching the required pressure, a signal is given to drive the pressing cylinder 4 to lift the main roller. The main roller receives the signal and moves to press the surface of the workpiece, and a linkage signal is given to the driven cylinder 10 corresponding to the driven wheel to perform linkage rolling. When the rolling reaches the required size, a main roller exit signal is given, and the main roller retreats into place with the pressing cylinder 4 and gives a signal to the lateral clamping cylinder 5. The lateral clamping cylinder 5 retreats into place and gives a signal to the next manipulator. The next manipulator takes away the rolled workpiece and gives a signal to the driven cylinder 10 of the driven roller at the same time. The driven roller retreats into place, and the next cycle continues.
