Description
Technical field
The utility model belongs to metal working equipment technical field, relates generally to a kind of tube opening set round device.
Background technique
In tubing production process, there is a phenomenon where ellipse be it is common, ovality is unsatisfactory for the tubing of quality requirement, tubing without
Method carries out nozzle butt welding, directly affects the welding performance requirement of tubing.Tubing, which generates oval reason, rolling or drawing process
Control improper the reason of causing.Also there are otherwise reason, the tubing of especially big specification, in annealing process, due to certainly
The reason of weight can also generate tubing ellipse.Ovality is one of the standard that pipe workpiece quality is examined, very it is worth we pay attention to.
Therefore, in order to improve yield rate, it is ensured that the welding performance of pipe material product needs in production through technique and equipment
Improve the ovality quality for improving tubing.
Utility model content
For the ovality quality problems for solving aforementioned tubes, the purpose of this utility model is to propose a kind of tube opening set round
Device.
The utility model is to complete above-mentioned purpose to adopt the following technical scheme that
A kind of tube opening set round device, the set round device have outer toroid；The internal diameter of the outer toroid is greater than pipe
The outer diameter of material；Four nuts being uniformly distributed along the circumference are welded in the outer toroid；Corresponding each nut is provided with bolt；The spiral shell
Bolt passes through corresponding nut, and end is contacted by metal gasket with the tubing；The metal gasket is arc plate.
The utility model proposes a kind of tube opening set round device, by adjusting four bolts, outer active force is in pipe
Material nozzle brings it about deformation, becomes round from ellipse.The device of this tube opening set round is easy to use and operate, structure letter
Single, use is safe, can effectively improve tubing ovality quality.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1, outer toroid, 2, bolt, 3, metal gasket, 4, nut, 5, tubing.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of device of tube opening set round, the set round device are made of three parts, outer toroid
1,2 nut 4 of bolt and metal gasket 3；Outer toroid is provided with four nuts 4, by being welded and fixed, assembles bolt 2, bolt 2 is logical
Threaded adjustment height is crossed, metal gasket 3 is the arc plate with certain radian with 5 same material of tubing, and metal gasket 3 is padded in spiral shell
On the bolt column of bolt 2, major function is that bolt 2 causes mass defect to 5 surface of tubing during set round in order to prevent.
The utility model proposes a kind of tube opening set round device, by adjusting four bolts, outer active force is in pipe
Material nozzle brings it about deformation, becomes round from ellipse.The device of this tube opening set round is easy to use and operate, structure letter
Single, use is safe, can effectively improve tubing ovality quality.
