Embodiment Construction
[0010] The specific implementation manner of the present invention will be further described below in conjunction with the accompanying drawings.
[0011] like figure 1 , 2 As shown, the tip elimination device of the seamless pipe mechanical press-in continuous rolling mill includes a set of press-in screw nut screw pairs, and a set of driving press-in screw pairs corresponding to the set of press-in screw nut screw pairs. The motor reducer 8 and the worm gear reducer 9 of the screw mandrel 6, and the displacement sensor 7 arranged at the end of each pressing screw mandrel 6, are characterized in that they are outside the pressing screw mandrel 6 of each mechanical pressing type continuous rolling mill. There are rotating disks 1 connected to the 5 places of the archway, and earrings 2 are arranged on each rotating disk 1. A connecting rod 3 is connected between the earrings 2, and the earrings 2 of the rotating disk 1 at the end are connected to each other. The side is prov...

The invention belongs to the technical field of continuous mills, and particularly relates to a sharpening device for a mechanical press-in type continuous mill of a seamless tube. The sharpening device comprises a group of press-in lead screw and nut screw pairs, a group of motor reducers and worm reducers for driving press-in lead screws, and displacement sensors arranged at the end parts of the press-in lead screws, and is characterized in that a rotating disk is connected with the external discharge part of each press-in lead screw of the mechanical press-in type continuous mill, wherein an earing is arranged on each rotating disk; a connecting pull rod is connected among the earings; a sharpening hydraulic cylinder is arranged on one side of the earing of the rotating disk at the end part; the output end of the sharpening hydraulic cylinder is connected with the earing of the rotating disk at the end part; the motor reducers and the worm reducers for driving the press- in lead screws are fixedly connected with the corresponding rotating disks. The sharpening device disclosed by the invention can solve the problem of the big deviation of wall thicknesses of the head part and the tail part of a rolled steel pipe, so as to improve the continuous rolling quality of the seamless tube, increase the product yield and greatly lower the cost.
Description
technical field [0001] The invention belongs to the technical field of continuous rolling mill equipment, and in particular relates to a sharpening device for a seamless pipe mechanical pressing continuous rolling mill. Background technique [0002] The sharpening function of the seamless steel pipe continuous rolling mill is a technology to control the wall thickness of the steel pipe head and tail when rolling the seamless pipe. The sharpening function plays an extremely important role in improving the rolling quality of steel pipes, increasing the yield and reducing costs. At present, there are two types of pressing methods for continuous rolling mills of seamless steel pipes in the world: mechanical screw pressing type and hydraulic servo pressing type. At present, only the hydraulic servo pressing continuous rolling mill has realized the sharpening function, but the control technology of the hydraulic servo pressing continuous rolling mill's sharpening function is comp...
