Abstract
The utility model relates to a stamping lap joint flange assembly comprising a flange plate and a pressing plate, wherein the middle part of the flange plate is provided with a first circular hole; four circular holes are evenly distributed around the flange plate; the edge of the first circular hole is provided with a step groove; the middle part of the pressing plate is provided with a middle hole; the inner edge of the middle hole is provided with a bulge layer; and the pressing plate and the flange plate are buckled with each other through the butt joint of the bulge layer and the step groove. The utility model has the advantages that the traditional lap joint flange can form the lap joint flange assembly together with a stamping flanging connected with a pipe fitting and various shapes of pressing plates. The lap joint flange assembly can be disassembled and is very flexible to use.
Description
Technical field
The utility model relates to a kind of lap joint flange combination of punching press.
Background technique
Flange has integral (type) flange, lap joint flange and screwed flange by structural type.Common integral (type) flange has welded flange and welding neckflange.The rigidity of welded flange is relatively poor, is applicable to the occasion of pressure p≤4MPa; Welding neckflange claims hubbed flange again, and rigidity is bigger, is applicable to the occasion that pressure and temp is higher.The pattern of flange facing has three kinds: the plane sealing surface is applicable to the occasion that pressure is not high, medium is nontoxic; Male-female seal contact face is applicable to the occasion that pressure is high slightly; Tongue and groove seal contact face is applicable to inflammable, explosive, poisonous medium and the higher occasion of pressure, and the thickness of the flange plate of different pressures is different with connecting bolt diameter and quantity.Existing flange generally forges, the cost height, and be that welding is fit, use is inconvenient, versatility is not strong yet.
The model utility content
The purpose of this utility model provides a kind of lap joint flange combination of punching press, solve existing flange and be forge and cost is high and be that welding is fit, use problems such as inconvenient, that versatility is not strong yet.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of lap joint flange combination of punching press, comprise flange plate and pressing plate, the middle part of described flange plate is provided with first circular hole, be evenly distributed with four circular holes around the flange plate, the edge of first circular hole is provided with step groove, the middle part of described pressing plate is provided with mesopore, and the interior edge of mesopore is provided with convexity layer, fastens by docking mutually of convexity layer and step groove between pressing plate and the flange plate.
The beneficial effects of the utility model are: present this lap joint flange is formed lap joint flange combination by the pressing plate of punching press flange that can be connected with pipe fitting and different shape, can separately disintegrate, and it is strong to use flexibility.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the flange plate plan view of the lap joint flange combination of the described punching press of the utility model embodiment;
Fig. 2 is the flange plate reverse view of the lap joint flange combination of the described punching press of the utility model embodiment;
Fig. 3 is the pressing plate plan view of the lap joint flange combination of the described punching press of the utility model embodiment;
Fig. 4 is the pressing plate reverse view of the lap joint flange combination of the described punching press of the utility model embodiment.
Among the figure:
1, flange plate; 2, pressing plate; 3, first circular hole; 4, circular hole; 5, step groove; 6, mesopore; 7, convexity layer.
Embodiment
Shown in Fig. 1-4, the lap joint flange combination of the described a kind of punching press of the utility model embodiment, comprise flange plate 1 and pressing plate 2, the middle part of described flange plate 1 is provided with first circular hole 3, be evenly distributed with four circular holes 4 around the flange plate 1, the edge of first circular hole 3 is provided with step groove 5, the middle part of described pressing plate 2 is provided with mesopore 6, the interior edge of mesopore 6 is provided with convexity layer 7, the diameter that the middle part that the middle part of flange plate 1 is provided with first circular hole 3 and pressing plate 2 is provided with mesopore 6 is identical, fastens by convexity layer 7 and docking mutually of step groove 5 between pressing plate 2 and the flange plate 1.
During use, because the flange plate and the pressing plate of this flange can separate, very easy to use, in use, pressing plate can be replaced with different shape, improved the versatility and the flexibility of a flange greatly, the lap joint flange combination of this punching press adopts the punching press flange that is connected with pipe fitting to make it improve sealability greatly.
Claims (1)
