Example Embodiment

[0018] The present invention will be further described in detail below in conjunction with the drawings:

[0019] In the following description, many specific details are explained in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described here, and those skilled in the art can do it without departing from the connotation of the present invention. Similar promotion, therefore, the present invention is not limited by the specific embodiments disclosed below.

[0020] In view of the problem that ring blanks of different shapes cannot be produced at the same time, the main roll replacement cycle is long and the bearing is damaged, the main roll is divided, and the combined main roll is designed and manufactured to reduce the roll change cycle and realize the ring blanks of different shapes in the same CNC rolling Produced on the ring machine.

[0021] Such as figure 1 , 2 As shown, the present inven...

Abstract

The invention discloses a combined main roll of a ring rolling mill, and relates to the technical field of metal rolling mill rolls. The main roll comprises a main roll body with a vertical passing hole formed in the middle, and two or more forming tiles fixed to the periphery of the main roll body through bolts. Because the multiple forming tiles are fixedly connected to the periphery of the main roll body through the bolts, it is only needed to replace the forming tiles with different ones when different ring blanks are manufactured, so that the replacement time of the main roll is shortened, the different shapes of ring blanks are produced at the same time, the working efficiency is improved, and the manufacturing cost of the main roll is lowered.

Description

technical field [0001] The invention relates to the technical field of metal rolling mill rolls, in particular to a combined main roll of a ring rolling machine which is easy to use. Background technique [0002] In the production of large-scale ring parts, the production process adopted is generally to use a CNC ring rolling machine to make a blank ring, and then machine the blank ring into shape. The finished shape of rough ring forgings can be roughly divided into two categories: stepped shape and straight barrel shape, such as image 3 Shown is a blank drawing of a stepped ring type part, Figure 4 The blank diagram of straight barrel rings is shown, and different shapes of rolls are required for forging ring parts of different shapes. The radial and axial CNC ring rolling machine mainly uses the main roll, core roll and tapered roll to form the ring blank, such as Figure 5 , 6 shown. At present, different molds are required for rolling ring blanks of different shap...
