Abstract
The utility model relates to a H shaped steel preparation field specifically is an anti -deformation frock of preparation H shaped steel. An anti -deformation frock of preparation H shaped steel, is including the press that is equipped with press base and press aircraft nose, open downwards at the upper surface middle part of press base has the slide, the bilateral symmetry of slide is equipped with a pair of clamp bolt, be fixed with a connecting plate through one of them clamp bolt, another clamp bolt is fixed with child board under the limit deflection, still be equipped with a spacing angle steel between connecting plate and the slide, the vertical section of spacing angle steel is near the one end towards the slide, and the child board all extends to the slide direction and does not nevertheless all cross the slide under the horizontal segment of spacing angle steel and the limit deflection, spacing angle steel horizontal segment and limit under the deflection child plate thickness the same. The utility model discloses an anti -deformation method adopts the frock to realize carrying out anti -deformation to H shaped steel pterygoid lamina, and offset with in advance anti -deformation mutually the welding back, and messenger's weldment reaches the roughness of design.
Description
Technical field
This utility model relates to H profile steel and makes field, a kind of Anti-deformation tooling making H profile steel.
Background technology
In order to save equipment making cost, H profile steel uses wing plate and web assembly welding to make molding, but the H profile steel of welding fabrication has the disadvantage that 1, the H profile steel deflection of welding fabrication is wayward.2, the deflection of H profile steel and material, welding manner, welding current size, speed of welding, rate of cooling many factors are relevant.Current welding method cannot well eliminate the problem on deformation brought in welding process.
Summary of the invention
This utility model is to solve the technical problem of welding deformation in current H profile steel manufacturing process, it is provided that a kind of Anti-deformation tooling making H profile steel.
This utility model adopts the following technical scheme that realization: a kind of Anti-deformation tooling making H profile steel, including being provided with press base and the forcing press of forcing press head；The upper surface middle part of press base has downwards slideway；Slideway be symmetrically arranged on two with a pair hold-down bolt；Being horizontally fixed with a connecting plate by one of them hold-down bolt, another hold-down bolt is horizontally fixed with tire plate under a limit deflection；A spacing angle steel it is additionally provided with between described connecting plate and slideway；The vertical section of spacing angle steel against connecting plate towards one end of slideway, under the horizontal segment of spacing angle steel and limit deflection tire plate respectively by two lateral slideway positions extensions but all do not cross slideway.
This utility model uses prestrain method, uses frock to realize H profile steel wing plate is carried out reversible deformation, offsets with reversible deformation in advance, and make weldment reach the flatness of design after welding.
When this utility model uses, tire plate under model, limit deflection (determining according to different thicknesss of slab, the test of plate width) is installed on forcing press by figure, make H profile steel and wing plate (by pressing plate material 6) is placed in frock appointment position, use forcing press that wing plate is suppressed, thus realize the reversible deformation to wing plate.
This utility model simple in construction, easily realizes；Not only prevent the deformation of H profile steel in manufacturing process, and reduce equipment cost, improve the quality that H profile steel makes, overcome the deficiencies in the prior art.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-press base, 2-slideway, 3-connecting plate, 4-hold-down bolt, the spacing angle steel of 5-, 6-is by pressing plate material, 7-forcing press head, tire plate under 8-limit deflection, 9-model.
Detailed description of the invention
A kind of Anti-deformation tooling making H profile steel, including being provided with press base 1 and the forcing press of forcing press head 7；The upper surface middle part of press base 1 has downwards slideway 2；Slideway 2 be symmetrically arranged on two with a pair hold-down bolt 4；Being horizontally fixed with a connecting plate 3 by one of them hold-down bolt 4, another hold-down bolt 4 is horizontally fixed with tire plate 8 under a limit deflection；A spacing angle steel 5 it is additionally provided with between described connecting plate 3 and slideway 2；The vertical section of spacing angle steel 5 against connecting plate 3 towards one end of slideway 2, under the horizontal segment of spacing angle steel 5 and limit deflection tire plate 8 respectively by two lateral slideway 2 positions extensions but all do not cross slideway 2.
Described slideway 2 longitudinal section is divided into the most rectangular two halves part up and down, and wherein the width of the latter half is more than the width of top half.
The practical distortion amount of H profile steel in welding process is determined according to result of the tests such as the leg height that H profile steel material, welding manner, welding current size, speed of welding, rate of cooling, web and the thickness ratio of wing plate and design require.Key element according to actual H profile steel determines anti-deformation, makes tire plate under model, limit deflection according to anti-deformation.Being installed on forcing press by Fig. 1 by tire plate under model, limit deflection, wing plate (by pressing plate material) is placed in frock and specifies position, wherein the vertical section of spacing angle steel 5 is withstood in one end；Use forcing press that wing plate is suppressed, thus realize the reversible deformation to wing plate, offset with reversible deformation in advance after H profile steel welding, so that the H profile steel making molding reaches the flatness that design requires.
Forcing press uses c-type hydraulic press, maximum opening degree 1500mm, nominal pressure 15MN.
