Abstract
The utility model discloses a non-ferrous metal pipeline shape correction tool. The non-ferrous metal pipeline shape correction tool is characterized by comprising an upper support plate (5) and a lower support plate (1) with symmetrical structures, wherein both the upper support plate (5) and the lower support plate (1) are provided with an arc surface which is matched with the arc of the inner wall of a corrected non-ferrous metal pipeline; a screw hole (4) is formed in each of the opposite surfaces of the upper support plate (5) and the lower support plate (1); one end of a double-end stud (3) is screwed into the screw hole (4) of the upper support plate (5); the other end of the double-end stud (3) is screwed into the screw hole (4) of the lower support plate (1); nuts (2) which have opposite screwing directions and support the corresponding upper support plate (5) and lower support plate (1) are respectively screwed with the two ends of the double-end stud (3). The non-ferrous metal pipeline shape correction tool is simple in structure and convenient to manufacture and use.
Description
Technical field
The utility model relates to a kind of pipeline processing technology, especially a kind of frock of the pipeline of welding fabrication being carried out to school circle, specifically a kind of non-ferrous metal pipe school type frock.
Background technology
At present, at the conventional straightening method of the pipeline to after welding fabrication, be to knock with mallet, the defect that this method exists has: can form mallet trace, pipeline mid portion at pipe surface can not school type, weld seam part because mallet class school type unbalance stress occurs that crackle, pipeline ovality global error scope are large, human resources consume excessive etc.Therefore, designing a kind of new school type frock is to improve the key of pipeline school type precision and efficiency.
Summary of the invention
The purpose of this utility model is for existing mallet, to hit formula school shape easily to cause the not high and inefficient problem of pipe deforming, precision, design a kind of can not only enhancing productivity, and can improve school type precision, prevent cracking, non-ferrous metal pipe school type frock that especially can butt welded seam place school type.
The technical solution of the utility model is:
A kind of non-ferrous metal pipe school type frock, it is characterized in that it comprises upper backup pad 5 and the lower supporting plate 1 of symmetrical configuration, described upper backup pad 5 and lower supporting plate 1 be equipped with one with the arc surface being matched by school non-ferrous metal pipe inwall circular arc, in upper backup pad 5 one side relative with lower supporting plate 1, be equipped with screw 4, one end of studs 3 screws in the screw 6 on upper backup pad 5, the other end screws on the screw 4 on lower supporting plate 1, at the two ends of described studs 3, be installed with respectively a rotation direction contrary, work the nut 2 that supports corresponding upper backup pad 5 and lower supporting plate 1.
The nut 2 that install studs 3 upper ends is left-handed nut, and the nut 2 that install lower end is right-handed nut.
Described upper backup pad 5 is provided with a groove 6 matching with non-ferrous metal pipe weld seam.
The beneficial effects of the utility model:
The utlity model has controllability good, easy and simple to handle, the advantage that pipeline is stressed evenly, can improve the efficiency of pipeline school type, it has avoided the defect of traditional mallet class school type, can not produce school type vestige, can carry out that school type, weld seam partly there will not be because unbalance stress cracks, pipeline ovality global error scope is less to pipeline mid portion, human resources consume too small etc.
The utility model is simple in structure, manufacture, easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the left view of Fig. 2.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As Figure 1-3.
A kind of non-ferrous metal pipe school type frock, it comprises upper backup pad 5 and the lower supporting plate 1 of symmetrical configuration, described upper backup pad 5 and lower supporting plate 1 be equipped with one with the arc surface being matched by school non-ferrous metal pipe inwall circular arc, in upper backup pad 5 one side relative with lower supporting plate 1, be equipped with two rows of screw 4(, as shown in Figure 1,3.), one end of studs 3 screws in the screw 6 on upper backup pad 5, the other end screws on the screw 4 on lower supporting plate 1, at the two ends of described studs 3, be installed with respectively a rotation direction contrary, work the nut 2 that supports corresponding upper backup pad 5 and lower supporting plate 1, the nut 2 that wherein install upper end is left-handed nut, the nut 2 that install lower end is right-handed nut, as shown in Figure 1, in Fig. 1, broken circle represents to treat the non-ferrous metal pipe of school type, the groove 6 on upper backup pad 5 tops arranges in order to adapt to the needs of weld seam, groove 6 is axial arranged along non-ferrous metal pipe, as Fig. 2.
Using method of the present utility model is that frock of the present utility model is packed in pipeline, by rotating upper lower nut 2, upper and lower support plate is strutted, thereby make pipeline inner circle consistent with the radian of upper and lower support plate, after a direction stretching, can unclamp frock and turn over certain angle and support again swollen school type.In order to guarantee ovality, the radian of upper and lower support plate should match with internal diameter of the pipeline.Therefore, before manufacture, should process corresponding upper and lower support plate according to the diameter of pipeline.
The utility model does not relate to partly all prior aries that maybe can adopt same as the prior art to be realized.
Claims (3)
1. a non-ferrous metal pipe school type frock, it is characterized in that it comprises upper backup pad (5) and the lower supporting plate (1) of symmetrical configuration, described upper backup pad (5) and lower supporting plate (1) be equipped with one with the arc surface being matched by school non-ferrous metal pipe inwall circular arc, in upper backup pad (5) one side relative with lower supporting plate (1), be equipped with screw (4), one end of studs (3) screws in the screw (6) on upper backup pad (5), the other end screws on the screw (4) on lower supporting plate (1), at the two ends of described studs (3), be installed with respectively a rotation direction contrary, work the nut (2) that supports corresponding upper backup pad (5) and lower supporting plate (1).
