A cone machine

Abstract

The invention discloses a tapered pipe machine. The tapered pipe machine comprises an engine base, a main shaft and an idler wheel, wherein the main shaft comprises a mould part and a power part; a mould cavity is formed in the radial direction of the mould part, and is internally provided with a mould plate; the main shaft is sleeved with the idler wheel; the mould plate comprises an impacting plate and a striking plate; the impacting plate is mounted in the mould cavity and can slide along the radial direction of the main shaft; the mould part is provided with a mould hole; the power part is provided with a positioning hole; the mould hole and the positioning hole are separated by a separation plate; a plurality of adjusting holes are formed in the axial direction of the main shaft; the striking plate is provided with a positioning part and is arranged inside the mould hole along the adjusting holes and the positioning part penetrates through the separation plate to enter the positioning hole; the positioning hole is internally provided with a positioning mechanism; the positioning mechanism can drive the striking plate to move along the axial direction of the main shaft; an oil inlet is formed in one side of the engine base and an oil outlet is formed in the other side of the engine base; lubricating oil can flow in a space between the main shaft and the idler wheel. The tapered pipe machine has the advantages of convenience for adjustment, simple structure and low noises.

Description

technical field [0001] The invention belongs to the technical field of metal extrusion, and relates to a tapered pipe machine. Background technique [0002] The tapered pipe machine is a machine tool for forging and elongating the pipe fittings into a cylindrical or conical shape through cold forging. With the cooperation of reasonable molds, it can process tapered workpieces with relatively ideal strength and smoothness. [0003] Chinese patent CN102699083A discloses a steel pipe taper machine, which includes a machine base, a housing on the machine base, and a main shaft driven by a motor. A mold and a hammer are installed in the mold cavity of the main shaft. There is a roller group, the hammer head includes a plurality of hammer head blocks, and the mold is composed of at least three mold blocks. The joint part of each mold block is triangular, and a part of the conical surface groove is set on the top side of the joint part. There is a gap between the two side walls of...

AI Technical Summary

Problems solved by technology

[0004] The mold block and its hammer head block in the above-mentioned tapered tube machine slide in the mold cavity of the main shaft along the radial direction of the main shaft, which is inconvenient to adjust in the axial direction; Inconvenient; there is no noise reduction measure, and the machine is noisy, so it is necessary to improve
