Outward rotation type oxygen-free copper pipe outer groove rolling mill

Abstract

The invention provides an outward rotation type oxygen-free copper pipe outer groove rolling mill and relates to the technical field of oxygen-free copper pipe outer groove rolling mills. The outward rotation type oxygen-free copper pipe outer groove rolling mill comprises two base plates and fixing devices, wherein two supporting frames are evenly and fixedly connected to the upper surfaces of the two base plates through bolts, driving blocks are slidably connected to the inner walls of the supporting frames respectively, bearings are fixedly connected to the surfaces of the driving blocks respectively, rolling shafts are movably connected to the inner walls of the two bearings respectively, the fixing devices are arranged on the surfaces of the bearings respectively, each fixing device comprises a round pipe, one end of each round pipe is welded to an inner ring of the corresponding bearing, a U-shaped plate is fixedly connected to the arc surface of each round pipe, an insertion rod is slidably connected to the surface of each U-shaped plate, and one end of each insertion rod sequentially penetrates through the corresponding round pipe and the corresponding rolling shaft in a sliding mode. By using the outward rotation type oxygen-free copper pipe outer groove rolling mill disclosed by the invention, the problems that a rolling shaft of a traditional rolling mill is inconvenient to replace, when grooves of different sizes need to be pressed on the surface of an oxygen-free copper pipe, a complex rolling shaft connecting mode is inconvenient to replace, and the processing efficiency of the rolling mill on the oxygen-free copper pipe is weakened are solved.

Description

technical field [0001] The invention relates to the technical field of an oxygen-free copper tube external groove rolling mill, in particular to an externally rotating oxygen-free copper tube external groove rolling mill. Background technique [0002] Rolling mill is the equipment that realizes the metal rolling process. It generally refers to the equipment that completes the whole process of rolling material production. The ordinary rolling mill is mainly composed of rollers, racks, roll distance adjustment devices, roll temperature adjustment devices, transmission devices, lubrication systems, control systems and It is composed of roller removal device and so on. [0003] When using a rolling mill to process oxygen-free copper tubes, it is inconvenient to replace the rollers of the traditional rolling mill. When it is necessary to press grooves of different sizes on the surface of the oxygen-free copper tubes, the complicated roller connection method is inconvenient to rep...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the inconvenient replacement of the rollers of the traditional rolling mill in the prior art. When grooves of different sizes need to be pressed on the surface of the oxygen-free copper pipe, the complicated roller connection method is inconvenient to replace. Reduced the shortcomings of the processing efficiency of the rolling mill for oxygen-free copper tubes, and proposed an externally rotating oxygen-free copper tube external groove rolling mill
