Abstract
The utility model discloses an internal support fixture for splicing large flanges. The internal support fixture comprises two arc-shaped plates which are manufactured based on the inside diameters of the flanges; the two arc-shaped plates are connected through two steel tubes; a rigid fixed support is welded between the two arc-shaped plates; and the outer sides, aligned with the spliced parts of the flanges, of the arc-shaped plates are provided with welding notches. The two arc-shaped plates are connected through the two steel tubes, and the rigid fixed support is welded between the two arc-shaped plates, thus the roundness of the spliced flanges is ensured to be within an allowable tolerance range; and the outer sides, aligned with the spliced parts of the flanges, of the arc-shaped plates are provided with the welding notches, thus welding work can be carried out smoothly and conveniently. Compared with the prior art, the fixture disclosed by the utility model is applied to the field splicing of the flanges, thus raw materials used for manufacturing the flanges can be reduced and the transportation cost can be lowered; and the fixture is simple to manufacture, can be used for simply and effectively controlling the splicing deformation of the large flanges, and has the advantage of facilitating the manufacture and transportation of the flanges.
Description
Technical field
The utility model relates to a kind of flange splicing and uses frock, relates in particular to a kind of large-sized flange splicing and uses 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.
The utility model content
The purpose of the utility model 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 purpose of the utility model 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.
The beneficial effect of the utility model is: through with 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; Through in the outside of arc plate and the jointing positions of alignment and flange all offer welding and use gap; Made things convenient for welding job to carry out smoothly, the contrast prior art is through applying to this frock 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 utility model is further explained with reference to the accompanying drawings below.
Fig. 1 is the structural representation of the described a kind of large-sized flange splicing of the utility model 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 the described a kind of large-sized flange splicing of the utility model, 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.
