Abstract
The utility model discloses a device for straightening a metal thin-wall expand tube, which comprises a spring sleeve (1), a mandril (2), a tip (3), a roller (4) and a cutter bar (5). When in use, the roller (4) and the cutter bar (5) are assembled to form a roller which can roll and is arranged on a tool rest of a lathe; the minor-diameter part of the spring sleeve (1) is clamped on a lathe chuck (6); the minor-diameter of a step of the mandril (2) is inserted into an inner hole at one end of the metal thin-wall expand tube; the major-diameter of the step of the mandril (2) is arranged into the inner hole of the spring sleeve (1); the major-diameter of the step of the tip (3) is clamped on a lathe tailstock (7); and the major-diameter of the step is inserted into an inner hole at the other end of the metal thin-wall expand tube, so that the metal thin-wall expand tube is fixed on the lathe. By starting the lathe, moving the tool rest of the lathe and uniformly applying force to straighten the bent metal thin-wall expand tube through the roller (4), the utility model solves the technical problem that the metal thin-wall expand tube is bent and deformed. The utility model has the characteristics of simple structure, easy disassembly, convenient operation, safety, reliability and the like.
Description
Technical field
The utility model relates to the device and method of a kind of metal expand tube alignment on lathe, is applicable to the axial bending distortion alignment of multiple metal material thin-walled expand tube, is particularly suitable for the alignment of carbon element steel alloy thin-walled expand tube.
Technical background
Metal pipe material has been widely used in a plurality of industrial departments such as space flight, navigation, weapons, automobile, agricultural machinery, and its linearity is had relatively high expectations, and the alignment technology is technological difficulties.Because after the axial compression of light-wall pipe blank motive was expanded, pipe was axially understood flexural deformation, aligning method in the past is directly to knock the tube bending change to open the place, perhaps adopts axle to run through the alignment of pipe endoporus, and preceding a kind of method is knocked and can be made the pipe radial deformation because tube wall is thin; A kind of method pipe in back still can produce bending after axle is taken out.Therefore need the simple and direct method of a kind of convenience, to axial bending distortion the carrying out alignment of metal material thin-walled expand tube.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, be easy to dismantle, easy to operate and safe and reliable on lathe the device of alignment metal thin-wall expand tube.
The device of alignment metal thin-wall expand tube comprises on the lathe described in the utility model:
Spring housing (1)---a kind of step-like cylinder body that has open slot, the step path partly is clipped on the lathe dog, and the step large-diameter portion divides the end face of end face and lathe dog to fit.
Axle (2)---profile is step-like cylinder, and the step path inserts metal thin-wall expand tube endoporus.
Top (3)---external form is step-like cylinder, and the step path inserts metal thin-wall expand tube endoporus, and the big footpath of step is clipped on the lathe tailstock.
Running roller (4)---the pole that tool steel is made is loaded on the forked type bar of knife bar (5).
Knife bar (5)---external form is a forked type, is loaded on the lathe saddle, is used to install running roller.
During use, running roller (4) is assembled into a rotatable running roller with knife bar (5) and is installed on the knife rest of lathe, the path of spring housing (1) partly is clipped on the lathe chuck (6), the step path of axle (2) is inserted the endoporus of metal thin-wall expand tube one end, packed in the big footpath of step of axle (2) again in spring housing (1) endoporus, the big footpath of step of top (3) is clipped on the lathe tailstock (7), the step path inserts the endoporus of the metal thin-wall expand tube other end, so just the metal thin-wall expand tube has been fixed on the lathe, start lathe, moving of knife rest by lathe, utilize running roller (4) equably the application of force with the metal thin-wall expand tube alignment of bending.
Utilize the device of alignment metal thin-wall expand tube described in the utility model, making the flexural deformation of metal expand tube carry out alignment on lathe becomes possibility, easy to use, makes the metal thin-wall expand tube reach higher linearity requirement.
The utlity model has simple in structure, economical and practical, be easy to dismantle, easy to operate and safe and reliable characteristics, be applicable to the alignment of multiple metal thin-wall expand tube.
