Description

Technical Field

[0001] The utility model relates to a pipe rolling machine, in particular to a high-speed precision section forming machine feeding bed for rolling high-precision pipes. Background Art

[0002] During the rolling process of the tube, the tube rolling mill needs to realize the rotation and feeding functions of the tube through the cooperation of the feeding bed and the feeding trolley. The feeding bed is installed at the head and tail ends of the tube rolling mill and connected to the feeding trolley, so that on the one hand, the feeding bed drives the feeding trolley to move the tube horizontally, and on the other hand, the rotating light bar on the feeding bed drives the tube to rotate after rotating, so as to realize the rotation and feeding functions of the tube rolling mill for the tube. In view of this functional requirement, the rotating light bar of the existing feeding bed is generally connected by a flat key or spline structure, that is, the feeding trolley is connected by a long keyway structure, so that when the feeding trolley moves to any horizontal position, its transmission function can be realized. However, the defect of this connection structure is that, on the one hand, after the length of the keyway structure is increased, the precision requirements and processing costs of the rotating light bar will be greatly increased, and on the other hand, the feeding trolley will also apply shear force to the transmission key on the rotating light bar during the translation and rotation process, thereby causing the transmission key to be damaged by force and affecting its service life.

[0003] In addition, in order to achieve the synchronous movement of the screw rods on the two sides of the feeding trolley, the existing tube rolling mill needs to connect the screw rods on both sides to form an integrated rod structure. For this screw rod structure, the existing installation method of the screw rod is to connect the screw rod through bearings at the front and rear ends of the feeding bed, so that the end of the screw rod passes through the bearing and then connects to the transmission rod through a coupling; but the bearing connection method will cause the screw rod to be rigidly limited after connection, so that once the screw rods on the two feeding trolleys have positioning errors at the bearing connection position, it is difficult to install the transmission rod, which increases the positioning accuracy requirements for the screw rod.

[0004] Therefore, the feeding bed of the existing pipe rolling mill has the problems of difficult processing and assembly and poor working stability. Utility Model Content
