Technical field
The utility model relates to a kind of pre-deformation mold, particularly a kind of pre-reversible deformation mould for welded flange.
Background technology
Along with the fast development of modern industry, need more and more higher to mains supply, and steel tower is the capital equipment of mains supply, in steel tower manufacture process, flange is one of Common parts, when in iron tower of power transmission line component, steel pipe and flange ring are to angle welding, because heating during welding can cause flange angular deformation, therefore just there is gap in the contact surface laminating of Flange joint, and then affect member stress.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of pre-reversible deformation mould for welded flange, and during to avoid welding, stress deformation causes negative effect.
The technical solution adopted in the utility model is as follows: a kind of pre-reversible deformation mould for welded flange, comprise patrix and counterdie, described counterdie is positioned at the below of patrix, it is characterized in that: described patrix comprises upper mounted plate and cope match-plate pattern, described fixed head is connected with cope match-plate pattern by a tube connector, described fixed head is arranged on the top of tube connector, described cope match-plate pattern is positioned at the bottom of tube connector, cope match-plate pattern protrudes downwards and forms turbination structure, described counterdie comprises base plate, lower bolster, described lower bolster is arranged on base plate, lower bolster becomes obconic stitching surface to concave, described cope match-plate pattern and lower bolster are provided with several circumference of flange positioning marks, and several circumference of flange positioning mark position correspondences are arranged.
Further, described fixed head is square structure, and its top has 4 bolts hole.
Further, be evenly provided with many reinforcement gussets between described fixed head and cope match-plate pattern, strengthen gusset and radially distribute around tube connector.
Further, the junction of described base plate and lower bolster is provided with one stroke scale marker by a scale marker holder, and described stroke mark mark abutted with the edge of cope match-plate pattern and lower bolster.
Further, described circumference of flange positioning mark is triangular structure.
The utility model is some to circumference of flange positioning mark by all arranging on cope match-plate pattern and lower bolster, with reference to finding the concentric of flange when flange being inserted die cavity by circumference of flange positioning mark, to prevent the flange eccentric distortion suppressed, thus improve the precision of flange predeformation, when efficiently solving welding, stress deformation causes the problem of negative effect, the utility model structure is simple, and easy to operate, production efficiency is high.
Accompanying drawing explanation
Accompanying drawing 1 is the front view of the pre-reversible deformation mould for welded flange described in the utility model;
Accompanying drawing 2 is structural representations of the pre-reversible deformation mould for welded flange described in the utility model;
Accompanying drawing 3 is the partial enlarged drawings in A portion shown in accompanying drawing 1.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually, below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
As shown in Figure 1 and Figure 2, a kind of pre-reversible deformation mould for welded flange, comprise patrix 1 and counterdie 2, described counterdie 2 is positioned at the below of patrix 1, and patrix 1 matches with counterdie 2 and arranges.
Described patrix 1 comprises upper mounted plate 11 and cope match-plate pattern 13, described fixed head 11 is connected with cope match-plate pattern 13 by a tube connector 12, described fixed head 11 is arranged on the top of tube connector 12, fixed head 11 is square structure, its top has 4 bolts hole 14, for the connection between fixed head 11 and oil hydraulic cylinder; Described cope match-plate pattern 13 is positioned at the bottom of tube connector 12, cope match-plate pattern 13 is circular, cope match-plate pattern 13 protrudes downwards and forms turbination structure, further, many reinforcement gussets 15 are evenly provided with between described fixed head 11 and cope match-plate pattern 13, strengthening gusset 15 radially distributes around tube connector 12, to strengthen the bulk strength of patrix 1.
Described counterdie 2 comprises base plate 21, lower bolster 22, and described lower bolster 22 is arranged on base plate 21, and lower bolster 22 becomes obconic stitching surface to concave, and lower bolster 22 coordinates for suppressing flange forming with cope match-plate pattern 13; Described base plate 21 is provided with one stroke scale marker 24 with the junction of lower bolster 22 by a scale marker holder 23, and stroke mark mark 24 abutted with the edge of cope match-plate pattern 13 and lower bolster 22, for showing the travel position of cope match-plate pattern 13.
As further improvement of the utility model, described cope match-plate pattern 13 and lower bolster 22 are provided with several circumference of flange positioning marks 3, and several circumference of flange positioning mark 3 position correspondences are arranged, as shown in Figure 3, for the circumference of flange positioning mark 3 on cope match-plate pattern 13, described circumference of flange positioning mark 3 is triangular structure, when cope match-plate pattern 13 and lower bolster 22 matched moulds, two circumference of flange positioning marks 3 on cope match-plate pattern 13 and lower bolster 22 form a diamond structure, circumference of flange positioning mark 3 is put to concentric with reference to finding during die cavity for flange to be pressed, to prevent the flange sideslip suppressed, the position of circumference of flange positioning mark 3 is drawn by the flange calculation of different size.
