Abstract
The utility model relates to a continuous-stretching alignment device for section bars, which comprises an automatic alignment mold sleeve, a stretching mold and a stretching lathe head. The stretching mold is in interference fit with the automatic alignment mold sleeve which is located on the stretching lathe head, and the length of the automatic alignment mold sleeve can be adjusted according to the thickness of a machine head board of the stretching lathe head. The automatic alignment mold sleeve is provided with a taper capable of achieving an axial centering function in the stretching direction, and the taper ranges from 3 degrees to 6 degrees. A locating surface capable of preventing the stretching mold from rotating circumferentially is milled on the lateral side of the automatic alignment mold sleeve, and the width of the location surface is 20mm. The automatic alignment mold sleeve with the taper can achieve the axial centering function in the stretching direction, the locating surface with the width of 20mm can prevent the stretching mold from rotating circumferentially, so that locating of a front mold and a back mold or a plurality of stretching molds can be achieved, no circumferential rotation or front-back shifting can be generated, and irregular mold hole corresponding accuracy of front molds and back molds is improved.
Description
Technical field
The utility model relates to a kind of section bar and even draw aligning device, especially a kind of continuously elongated section bar of profile shapes product of complex contour that is applicable to even draws aligning device.
Background technology
In the prior art, when coloured and ferrous metal are produced complex-shaped profiled bar, need repeatedly its shaping to be stretched; Generally speaking, all need manual work to align before each the stretching, if shape anomaly is complicated; The difficulty that manual work aligns strengthens, and the time is long, and efficient is low.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of above-mentioned existence, passes through two (or a plurality of) and aligns the die sleeve device automatically and can realize that the continuously elongated section bar of special-shaped material connects and draw aligning device and provide a kind of.
The purpose of the utility model is accomplished through following technical scheme, and it comprises and align die sleeve, drawing-die, the Extension bed head of a bed automatically, described drawing-die and align automatically and be interference fit between die sleeve; This aligns die sleeve automatically and is positioned at the Extension bed head of a bed, and adjusts the length that aligns die sleeve automatically according to the thickness of Extension bed headpiece.
As preferably, the described die sleeve that aligns automatically has the tapering that can realize the effect of draw direction axial alignment, and the scope of this tapering is 3 ~ 6 °; This avris that aligns die sleeve automatically is milled with one can prevent the locating surface that drawing-die rotates in a circumferential direction, and this location face width is 20 ㎜.
As preferably, it is 3 ~ 6 ° tapering that described drawing-die inboard has scope.
The aligning die sleeve automatically and can realize the effect of draw direction axial alignment of the utility model band tapering; The locating surface of wide 20 ㎜ can prevent rotating in a circumferential direction of drawing-die; Realize that former and later two or a plurality of drawing-die locate automatically; Nothing rotates in a circumferential direction and the front and back play, and the corresponding precision of the special-shaped nib of moulds can improve its production efficiency and product precision and quality before and after having strengthened.

Fig. 3 is the garland rod finished product cross sectional shape sketch map of the utility model.
Fig. 4 is a chip-removal hole positional structure sketch map between two drawing-die of the utility model.
Label in the accompanying drawing is respectively: 1, drawing-die, 2, align die sleeve automatically, 2-1, locating surface, 3, chip-removal hole.
The specific embodiment
To combine below accompanying drawing to the utility model be detailed introduction: Fig. 1, shown in 2, the utility model comprises and aligns die sleeve 2, drawing-die 1, the Extension bed head of a bed automatically, described drawing-die 1 and align 2 of die sleeves automatically and be interference fit; This aligns die sleeve 2 automatically and is positioned at the Extension bed head of a bed, and adjusts the length that aligns die sleeve 2 automatically according to the thickness of Extension bed headpiece.
The described die sleeve 2 that aligns automatically has the tapering that can realize the effect of draw direction axial alignment, and the scope of this tapering is 3 ~ 6 °; This avris that aligns die sleeve automatically is milled with one can prevent the locating surface 2-1 that drawing-die rotates in a circumferential direction, and this locating surface 2-1 wide be 20 ㎜; It is 3 ~ 6 ° tapering that described drawing-die 1 inboard has scope.
The utility model will align die sleeve 2 automatically and put into the Extension bed head of a bed, and the length that can align die sleeve 2 with the thickness adjustment according to the concrete Extension bed head of a bed automatically makes it and the head of a bed that stretches is complementary.With this product garland rod is example; The bar that desire stretches is made head earlier; Its length is for align die sleeve length+stretching-machine jaw clamping length automatically; Pass two drawing-die 1 successively: promptly pole is stretched to trimmed size size (see figure 3) through twice (secondary reshaping garland head time shaping cross section maximum gauge) drawing-die shaping again after (a shaping garland head time shaping cross section maximum gauge) drawing-die shaping stretches.Secondary reshaping stretching drawing-die places and aligns die sleeve 2 front ends automatically, and a shaping stretching drawing-die places and aligns die sleeve 2 rear ends automatically, is provided with chip-removal hole 3 (see figure 4)s between two drawing-die 1, can the scurf of taking off of secondary reshaping be discharged from chip-removal hole 3.Secondary reshaping can be accomplished (promptly two even drawing) in the one-off drawing process.
Except that the foregoing description, all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
