Embodiment Construction
[0017] Embodiments of the invention are:
[0018] The three-roller Y-shaped rolling mill stand of the frame type structure is constructed by connecting the main frame 5 and the sub-frame 6 through bolts. window. The frame is an axisymmetric hexagon, with a hole for setting the roll pressing mechanism on the plane perpendicular to the radial direction of the roll, and a hole for introducing the roll transmission mechanism on the plane perpendicular to the axial direction of the roll. The sub-frame is a plane frame, accurately positioned with the main frame through positioning pins, and connected with the main frame by bolts.

A framework of a Y-shaped rolling mill with three rolls belongs to the technical field of metal bar and pipe rolling and has the advantages of high strength, high rigidity and convenience in regulation and replacement of roll devices. The framework is characterized by having a framed structure and consisting of a main frame and an auxiliary frame, wherein the main frame and the auxiliary frame are connected integrally by bolts to form an axisymmetric hexahedron. Besides, the main frame is a spatial frame, four round holes on a plane perpendicular to the radial direction of rolls, triangular holes on a plane perpendicular to the rolling line, round holes on a plane perpendicular to the axial direction of the rolls and rectangular holes at mounting positions of the rolls are respectively arranged on the main frame along the directions forming the included angle of 120 degrees, and a center hole is arranged at the center of the main frame. The auxiliary frame is a plane frame, and triangular holes on a plane perpendicular to the rolling line and rectangular holes at the mounting positions of the rolls are respectively arranged on the auxiliary frame along the directions forming the included angle of 120 degrees, and a center hole is arranged at the center of the auxiliary frame.
Description
technical field [0001] The invention belongs to the technical field of metal rolling, and in particular relates to equipment used in a production line for rolling metal rods, wires and pipes. Background technique [0002] At present, the three-roll Y-shaped rolling mill frame used in the rolling metal rod, wire and pipe production line mainly has two forms, one is a split structure, which is mainly used for rolling steel, such as figure 1 shown. The characteristic is that the frame is composed of two symmetrical plates or shells, the roll device is set in it, and then the two are connected as a whole by a screw. The disadvantages are: (1) The machine frame is difficult to process. (2) It is difficult to install and adjust the rolls. In many cases, online adjustment cannot be realized. To replace the rolls, the rolling mill must be completely disassembled. The other is a box-type structure, which is mostly used for rolling non-ferrous metal bars, such as figure 2 shown. ...
