Description
Technical Field
The utility model relates to a weld the dress, specifically a reduce frock of flange welding deformation.
Background
The dual-phase steel flat flange is different from a common stainless steel flange. Because the dual-phase steel flat flange is generally thinner, the dual-phase steel connecting pipe has the same characteristics, and because the function is required, the flatness requirement of the welded flange is not more than 1mm when the flange is welded with the dual-phase steel connecting pipe.
The current welding method has the following problems:
1. if no effective measures are taken, the welding is easy to deform and exceeds the range of the flatness requirement;
2. if no effective measures are taken, and the deformation is too large, the initiating explosive device is needed to be used for shape correction, and after the initiating explosive device is used for shape correction, the heat treatment and the solution treatment of the welded parts need to be added, so that the part cost is increased.
Therefore, it is important to ensure that the welding is not deformed.
SUMMERY OF THE UTILITY MODEL
For solving the defect of above-mentioned prior art, the utility model provides a reduce frock of flange welding deformation, the utility model discloses a circulating water produces deformation when reducing the dull and stereotyped flange of diphase steel and diphase steel takeover welding to the regional cooling of welding, makes it reach the drawing requirement, needs the corruption that the protection frock does not receive water simultaneously.
In order to achieve the technical purpose, the utility model adopts the following technical scheme: a tool for reducing welding deformation of a flange comprises a water tank, wherein a fixing buckle is fixed inside the water tank, the fixing buckle is arranged in a hollow mode, and a through hole is formed in the upper wall of the fixing buckle; a lower clamping plate is arranged inside the fixing buckle, a bolt is connected to the lower clamping plate, and the bolt penetrates through the through hole;
an upper clamping plate is arranged above the fixing buckle and connected with the bolt;
the two ends of the water tank are connected with hoses, and the hoses are provided with circulation.
Furthermore, the water tank is made of carbon steel, and paint is brushed on the inner surface of the water tank.
Furthermore, the fixing buckle, the upper clamping plate and the lower clamping plate are all made of stainless steel.
To sum up, the utility model discloses following technological effect has been gained:
1. the utility model is provided with the circulating pump and the hose, the water inlet and the water outlet of the water tank are connected together, the circulating flow of water can be realized through the circulating pump, and the circulation of cooling water is accelerated to ensure the accelerated reduction of heat during welding;
2. the utility model is provided with the upper clamping plate and the lower clamping plate, the flat flange can be effectively fixed by fixing the bolt and the nut, and the welding part can be conveniently taken out from the tool after the welding is finished;
3. when the cooling device is used, water is added in advance, so that the water inlet and outlet positions at the liquid level and 2/3 of the thickness of the flange are reasonably designed, and then the hose and the water pump are connected with the water inlet and the water outlet of the tool, so that cooling water is recycled, and the cooling effect is improved;
4. the utility model discloses a with paint and stainless steel's fastener, can effectively avoid the corrosive damage that the cooling water caused to the frock.
Drawings
Fig. 1 is a schematic view of a tool provided by an embodiment of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
Example (b):
as shown in fig. 1, a tool for reducing welding deformation of a flange comprises a water tank 1, a fixing buckle 2 is fixed inside the water tank 1, the fixing buckle 2 is arranged in a hollow manner, the upper wall of the fixing buckle 2 is provided with a through hole 21, the through hole 21 corresponds to a bolt hole on a flat flange 7, and the aperture of the through hole 21 is larger than that of the bolt hole, so that the tool is suitable for various flanges with the same outer diameter and different apertures, and has good adaptability; the inside lower plate 10 that is equipped with of fixed 2, the last bolt 5 that is connected with of lower plate 10, bolt 5 pass through the through-hole 21 setting, and fixed 2 tops of detaining are equipped with punch holder 3, and punch holder 3 is connected with bolt 5, and punch holder 3 presss from both sides dull and stereotyped flange 7 in the top of fixed 2 of detaining, utilizes bolt 5 fixed.
The both ends of water tank 1 are connected with hose 9, install circulation 8 on the hose 9, and when circulation pump 8 opened, the cooling water in the water tank 1 began the circulation, the cooling of accelerated temperature.
The water tank 1 is made of carbon steel, and paint is brushed on the inner surface of the water tank 1.
The fixing buckle 2, the upper splint 3 and the lower splint 10 are all made of stainless steel.
The working principle is as follows:
1. the flat flange 7 and the connecting pipe 6 are integrated into a whole at the head part in advance by spot welding;
2. the flat flange 7 is fixed on the fixing buckle 2 through the upper clamping plate 3, the lower clamping plate 10, the bolt 5 and the nut 4, and the through hole 21 of the fixing buckle 2 is large so as to adapt to flanges with the same outer diameter and different apertures;
