Abstract
The invention discloses an internal support fixture for splicing large flanges, which comprises two arc plates manufactured according to the bore dimensions of the flanges. The two arc plates are connected by two steel pipes, and a rigid fixing support is welded between the two arc plates, so that the roundness of the spliced flanges can be ensured to be within an allowable tolerance range. Notches for welding are arranged on the outer sides of the arc plates and at positions aligned to the spliced positions of the arc plates with the flanges, so that smooth welding is facilitated. Compared with the prior art, the internal support fixture has the advantages that by applying the fixture to flange splicing on site, raw materials used for manufacturing the flanges can be decreased and transport cost can be reduced, the fixture is simple in manufacture, splicing deformation of the large flanges can be controlled simply and effectively, and manufacture and transport of the flanges are facilitated.
Description
Technical field
The present invention relates to a kind of flange splicing and use frock, relate in particular to a kind of large-sized flange splicing and use interior supporting tool.
Background technology
Frock is the technological equipment of production process, and it is the general name of various tool used in the manufacture process.Comprise cutter, anchor clamps, mould, measurer, accessory, small tool, station instrument etc.Some large-scale flanges are because size is bigger, if when making, adopt the direct blanking of monoblock steel plate to form, not only the raw material size to steel plate has requirement; And waste is also very serious aspect the blanking of material, simultaneously because flange size may cause the inconvenience of transportation too greatly, so normal at present the employing is divided into several sections with large-sized flange; Be convenient to transportation, splice to the scene then, in the process of splicing; If adopt traditional joining method; Spliced flange roundness can exceed the margin of tolerance of permission, finally might cause whole flange to be scrapped because of being out of shape greatly, in splicing; How to guarantee that the flange roundness does not exceed the margin of tolerance of permission, becoming one has a difficult problem to be solved.
Summary of the invention
The objective of the invention is to address the above problem; Provide a kind of large-sized flange splicing to use interior supporting tool; It is the splicing distortion of control flange effectively; Make flange splicing back roundness in the margin of tolerance of permission, this frock applies to the on-the-spot splicing of flange, can improve the difficulty of the utilization rate of material, the cost that reduces transportation and solution transportation.
The objective of the invention is to realize through following technical scheme:
Interior supporting tool is used in a kind of large-sized flange splicing; Comprise two arc plates making with the flange internal diameter size; Connect through two steel pipes between said two arc plates; And welding rigidly fixes support between two arc plates, and the jointing positions of the outside of said arc plate and alignment and flange all offers welding and uses gap.
It is that 30mm, width are that the flat board of 150mm is processed that said arc plate adopts thickness.
Said steel pipe is the desirable center of circle of flange with the center that intersects of fixed support.
Said gap is of a size of 80mm * 60mm.
Beneficial effect of the present invention is: by connecting with two steel pipes between two arc plates; And welding rigidly fixes support between two arc plates; Can effectively prevent the welding deformation of flange when splicing, guarantee that spliced flange roundness is in the margin of tolerance that allows; By all offering the welding gap in the outside of arc plate and the jointing positions of alignment and flange; Made things convenient for welding job to carry out smoothly; The contrast prior art; By this frock being applied to the on-the-spot splicing of flange; Can reduce and make the employed raw material of flange and reduce cost of transportation; This frock making is simple, and splicing distortion that can simple and effective control large-sized flange has the making of being convenient to flange and the advantage of transportation.
Description of drawings
With embodiment the present invention is further explained with reference to the accompanying drawings below.
Fig. 1 is the structural representation of a kind of large-sized flange splicing of the present invention with interior supporting tool.
Among the figure:
1, arc plate; 2, fixed support; 3, steel pipe.
The specific embodiment
Among the embodiment as shown in Figure 1; Interior supporting tool is used in a kind of large-sized flange splicing of the present invention, comprises two arc plates 1 making with the flange internal diameter size, and it is 30mm that arc plate 1 adopts thickness; Width is that the flat board of 150mm is processed; Connect with two steel pipes 3 between two arc plates 1, and welding rigidly fixes and supports 2 between two arc plates 1, and the center that intersects of steel pipe 3 and fixed support 2 is the desirable center of circle of flange; In the outside of arc plate 1 and the jointing positions of alignment and flange all offer the gap of 80mm * 60mm, this gap is used for the flange welding.
