Cone bending machine

In order to make the groove first and then roll the cone tube, we use the upper roller of a machine that rolls both the cylinder and the cone plate as the active roller for 70 €? The 500 three roll plate rolling machine is designed with the following cone rolling device to roll the wind turbine cone tower. Based on the taper of the wind turbine tower, a cone sleeve consisting of three sections is designed for the upper roller. The cone sleeve is connected to the upper roller by a key, with an average thickness of 35mm. It is quenched and tempered and dynamically matched with the upper roller. The surfaces of the two lower rollers are quenched. A small clamping roller driven by an oil cylinder can also be installed in the space between the two lower rollers to clamp the workpiece and the upper roller, preventing them from sliding against each other. The actual rolling result showed that the workpiece with a thickness of 26mm and Q345 achieved good results without the need for clamping rollers due to the small taper of the workpiece. If the upper roller is also quenched, the disassembly and installation of the cone sleeve will be better. This is a combination of cone roller method and clamping roller method. Due to the cylindrical roller used for the lower roller and the roller sleeve used for the upper roller, the structure is simple and the cost is also low.
There are several types of gear shifting methods:
(1) Install a stop wheel on the upper roller on the overturning side: The stop wheel is installed in the transition section between the upper roller body and the bearing on the overturning side of the upper roller through axial and radial bearings. A part of the stop wheel is inserted into the overturning frame to restrict the stop wheel from rotating with the upper roller. The blocking wheel is generally in contact with the small head plate edge of the workpiece, mainly relying on the frictional force between the blocking wheel and the workpiece plate edge to achieve the rotational motion of the fan-shaped steel plate around a vertical line passing through a certain point on its own busbar. This method is suitable for workpieces with small plate thickness, large taper, and small head diameter.
(2) Install a stop wheel on the lower roller on the overturned side: The stop wheel is located on the two lower roller bearing seats on the overturned side, and is directly fixed to the upper part of the lower roller bearing seats. The working principle is the same as the first method, and it is suitable for workpieces with larger taper angles and smaller head diameters, with thicker plates than the first method.
(3) Install a stop wheel on the overturned side frame: The stop wheel is bolted onto the overturned side frame of the four roll plate rolling machine, with the upper plane of the stop wheel slightly higher than the lower busbar of the upper roll.
(4) Install stop wheels on the tipping frame: Install stop wheels on both sides of the upper roller on the tipping frame, and set short sliding keys between the tipping frame and the frame.
The above types of blocking wheels are installed on the flipping side because the flipping frame has a small external size and the flipping side frame is low, so the workpiece generally does not interfere with it. The blocking wheel is tightly attached to the work roll surface and can roll workpieces with larger taper and smaller head diameter.
(5) Install a stop wheel on the bed: The stop wheel frame is mounted on the bed with a pin shaft, and the stop wheel is installed on both sides of the roller. The stop wheel frame can rotate around the pin shaft, and the stop wheel can be raised and lowered inside the stop wheel frame.
(6) Install stop wheels on the transmission side frame: On the transmission side frame, there are large installation planes on both sides of the upper roller, which have selectable internal threads, trapezoidal grooves, or pin shafts, keys, etc. for fastening the stop wheel device, so that the relative position and direction of the stop wheel device to the working roller can be changed as needed. 3 methods to improve cone rolling ability
