Abstract
The utility model relates to a device for processing a thin-wall seamless elbow of a stainless steel U-shaped tube. The device comprises an elbow die and a stainless steel U-shaped tube to be bent, and also comprises a neck bush, wherein the diameter of the neck bush is the same as the diameter of the inner wall of the stainless steel U-shaped tube to be bent; and the neck bush is inserted into a bending point of the stainless steel U-shaped tube to be bent. The device for processing the thin-wall seamless elbow of the stainless steel U-shaped tube has the advantage that: the neck bush can block off the inward extruding force of the tube wall, so that the tube wall does not deform during the elbow shaping process.
Description
Technical field
The utility model relates to a kind of device of processing elbow, relates in particular to a kind of device of processing stainless steel U-shaped pipe thin-wall seamless elbows.
Background technology
The processing technology of Stainless Steel U pipe thin-wall seamless elbows is that the stainless steel pipe is arranged in the elbow module in the prior art, by hydraulic press the stainless steel pipe is advanced until moulding in elbow module.Because it is lower that the thin-wall steel tube tube wall supports the unstability critical force, deformation defects such as flat wrinkle often appear in crooked position.These defectives not only weaken the intensity of steel pipe, reduce its bearing capacity, and cause flow media speed inequality in the pipe, generation eddy current and crooked position to gather dirt etc. easily, and influence the normal use of bend pipe, therefore eliminating the bend pipe defective has become maximum difficult point in the bend pipe process.
Summary of the invention
The utility model technical issues that need to address have provided a kind of device of processing stainless steel U-shaped pipe thin-wall seamless elbows, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: elbow module and Stainless Steel U pipe to be curved; Also comprise: a neck bush; The diameter of described neck bush is identical with described Stainless Steel U inside pipe wall diameter to be curved; Described neck bush is inserted into the curved point of Stainless Steel U pipe to be curved.
Compared with prior art, the beneficial effects of the utility model are: lining then plays the extruding force that stops that tube wall is inside, and tube wall can be out of shape in the bend forming process.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is Figure 1A place partial schematic diagram.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
By Fig. 1, Fig. 2 as seen: the utility model comprises: elbow module (not shown) and Stainless Steel U pipe 1 to be curved; Also comprise: a neck bush 2; The diameter of described neck bush 2 is identical with described Stainless Steel U pipe 1 inner diameter to be curved; Described neck bush 2 is inserted into the curved point 11 of Stainless Steel U pipe 1 to be curved.
Described neck bush 2 inside also are provided with reinforcement.
The utility model is in the elbow module progradation at the stainless steel pipe, be provided with and the equal-sized neck bush of ips at this tube interior, then the stainless steel pipe is arranged in the elbow module, then the stainless steel pipe is advanced until moulding in elbow module by hydraulic press.Because the utility model is being provided with neck bush with stainless-steel pipe in steel pipe in the elbow module progradation, the inner diameter equal and opposite in direction of the size of this neck bush and steel pipe, and this bush inside also is provided with the intensity that is extruded that reinforcement increases lining, like this, steel pipe is in the bend forming process, if tube wall holds under the situation that can't stand the hydraulic press propulsive force, lining then plays the extruding force that stops that tube wall is inside, and tube wall can be out of shape in the bend forming process.
Employing the utility model has reduced the deformation defects such as flat wrinkle of U type pipe bent portion, has improved the quality of product.
