Abstract
The utility model discloses a clamp for preventing a flange from welding deformation, which comprises a connecting plate. A sleeve with an adjusting bolt arranged therein is connected to the upper end of the connecting plate; and a first adjusting screw nut is nested at the part of the adjusting bolt which is positioned at the upper part of the sleeve, and a second adjusting screw nut and a lock nut are nested at the part of the adjusting bolt which is positioned at the lower part of the sleeve. The clamp provided by the utility model has the advantages of small size, light weight, convenient and flexible clamping, and can be used singly or in combined manner according to specific structures. The planeness of the flange is adjusted by utilizing a bolt, so that the integral deformation of the entire flange and a wallboard caused by the input of welding heat is effectively prevented. The clamp is proved to be an effective method for controlling the deformation of the flange and ensuring the planeness by long time application, and the clamp has simple operation and can effectively reduce the manufacture cost of a product.
Description
Technical field
The utility model discloses a kind of anchor clamps that are used for the welding of large-diameter cylinder body flange, particularly a kind of anchor clamps that prevent the flange welding deformation.
Background technology
Along with the continuous development of global clean energy resource, the manufacturing factory of wind-power electricity generation pylon is increasing, and the product quality of pylon has been proposed more and more higher requirement.The master operation that pylon is made is welded exactly, and especially the welding job of flange and each shell ring is particularly important, and he directly has influence on the service life of whole pylon.Therefore, the flange welding is an important link, and extremely is difficult to control.The wind-power electricity generation flange is to adopt external suction flange substantially, costs an arm and a leg, so will there be fairly perfect manufacture craft to guarantee his enforcement.Common in the past way is that the method for attacking with fire and correcting is adopted in flange welding back, and its shortcoming is: 1, thermal stress is concentrated in the flange after the welding, and is bad as adopting the fire attack temperature to grasp, and can increase the weight of whole flange distortion amount, causes the result that can't save; 2, the metallographic structure of the whole material internal of the fire attack meeting of rectification influence changes for a long time, thereby influences the entire product quality; 3, promptly finish the making of product after welding is finished, expend time in and labour cost.
Summary of the invention
Goal of the invention: technical problem to be solved in the utility model is at the deficiencies in the prior art, and a kind of anchor clamps that prevent the flange welding deformation are provided.
Technical scheme: the utility model discloses a kind of anchor clamps that prevent the flange welding deformation, comprise connecting plate, upper end at connecting plate is connected with sleeve pipe, in sleeve pipe, be provided with the adjustment screw rod, the part that the adjustment screw rod is positioned at the sleeve pipe top is nested with first adjusting nut, and the part that the adjustment screw rod is positioned at the sleeve pipe below is nested with second adjusting nut and locking nut.
In the utility model, preferably, described connecting plate middle part is provided with inside depression, and the thickness of connecting plate bottom is less than the thickness on top.
Beneficial effect: it is little, in light weight that the anchor clamps that prevent the flange welding deformation described in the utility model have a volume, convenient mounting and clamping, flexible characteristic; According to concrete structure, can use use also capable of being combined separately.This anchor clamps use the way of regulating bolt to adjust the flatness of flange, and the input that can effectively prevent welding heat causes the bulk deformation of whole flange and wallboard.The utility model facts have proved it is the effective ways that a kind of control flange distortion guarantees flatness through long-term the use, and it is simple to operate, can effectively reduce the manufacturing cost of product.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is done further to specify, above-mentioned and/or otherwise advantage of the present utility model will become apparent.
Be illustrated as structural representation of the present utility model.
The specific embodiment:
As shown in the figure, the utility model discloses a kind of anchor clamps that prevent the flange welding deformation, comprise connecting plate 1, be connected with sleeve pipe 6 in the upper end of connecting plate, in sleeve pipe 6, be provided with and adjust screw rod 3, the part that adjustment screw rod 3 is positioned at sleeve pipe 6 tops is nested with first adjusting nut 5, and the part that adjustment screw rod 3 is positioned at sleeve pipe 6 belows is nested with second adjusting nut 4 and locking nut 2.Described connecting plate 1 middle part is provided with inside depression 7, and the thickness of connecting plate 1 bottom is less than the thickness on top.
In use: 1, should be earlier according to the size of whole screw rod 3 of the real auxiliary tone in the aperture of top flange 8 and sleeve pipe 6, after determining again with sleeve pipe 6 and connecting plate 1 firm welding; 2, the measurement flange need be adjusted after flange and shell ring were organized in advance position and measurement need adjustment amount, and connecting plate is fixed in this position; 3, according to the data that record, analyze using method, higher as flange in certain some position, then shorten " adjusting section " length, this point of flange is depressed into tightens all bolts behind the setting and get final product; 4, on the low side as certain some position, method is opposite with the last step; 5, all measure whether satisfy the flatness requirement after need adjusting an adjustment once more, if do not have, then need to finely tune once more, till qualified; 6, adjust a little and finish welding, stress release work after qualified, take off all anchor clamps.
These anchor clamps are looked the diameter of flange in use, the thickness of flange determines the quantity of employing.During use anchor clamps installation and needs are adjusted point.By regulating the flatness of bolt control flange, reach standard-required.
The utility model provides a kind of thinking and method that prevents the anchor clamps of flange welding deformation; the method and the approach of this technical scheme of specific implementation are a lot; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.The all available prior art of each component part not clear and definite in the present embodiment is realized.
