Abstract
The invention discloses a single-fin heat exchange tube sidewise bending calibrating device applied to the field of industrial boilers. The single-fin heat exchange tube sidewise bending calibrating device comprises a pedestal, wherein two fixed calibrating dies which are linearly distributed at an interval are fixedly arranged on the pedestal; blocking grooves passing through the whole fixed calibrating die are respectively formed at the same side surface of each fixed calibrating die; and the cross sections of the blocking grooves are in match with the cross sections of the single-fin heat exchange tubes in shape; a telescopic cylinder is fixedly arranged on the pedestal at one side of the blocking groove at the fixed calibrating die; movable calibrating dies are arranged on a piston rod of the telescopic cylinder; and the part between two fixed calibrating dies on the single-fin heat exchange tube can be knocked through the movable calibrating dies when the piston rod of the telescopic cylinder extends out. The single-fin heat exchange tube sidewise bending calibrating device has the advantages of simplicity in operation, and capability of quickly calibrating the flatness of heat exchange tubes under a sidewise bending condition.
Description
Technical field
The present invention relates to the fin heat exchanger tube, be specifically related to be used to proofread and correct the side sway means for correcting of single fin heat exchanger tube.
Background technology
In Industrial Boiler, heat exchanger tube is main heating part, and the quality of its heat exchange property directly influences the production efficiency of boiler; At present; In order to improve the heat exchange effect of heat exchanger tube, it vertically is welded with a fin in the heat exchange pipe external surface upper edge mostly, but in the welding process of fin; Can make heat exchanger tube produce phenomenons such as local side sway, distortion because of factor such as workman's misoperation, cause the glacing flatness of heat exchanger tube not meet the boiler component manufacturer's standard; This have the heat exchanger tube of local side sway phenomenon because the deviation of glacing flatness can not be carried out the meticulous assembling that cooperates with the miscellaneous part of boiler, need carry out could assembling with miscellaneous part after glacing flatness is proofreaied and correct to it.At present all be to adopt artificial baking method of correcting that the heat exchanger tube with side sway phenomenon is proofreaied and correct: promptly the operator exchanges the position that has the side sway phenomenon on the heat pipe earlier and toasts; To be heated to uniform temperature; Use aid such as jack that roof pressure is carried out at the side sway position and proofread and correct, but this method length consuming time, complicated operation, workload are big.
Summary of the invention
The purpose of this invention is to provide a kind of simple to operate, and can be fast prop up the means for correcting that the fin heat exchanger tube carries out the glacing flatness correction to list with side sway phenomenon.
For realizing above-mentioned purpose; The present invention has adopted following technical scheme: described list props up fin heat exchanger tube side sway means for correcting; Wherein: comprising: base; On base, be set with two fixed correction moulds linearly spaced apart, the same side of each fixed correction mould offers the draw-in groove that connects whole fixed correction mould respectively, and the shape of cross section of the shape of cross section of draw-in groove and single fin heat exchanger tube matches; On the base of the draw-in groove that is positioned at the fixed correction mould one side, be set with a telescopic cylinder; The piston rod of telescopic cylinder is provided with movable straightening die, and movable straightening die is knocked the position between two fixed correction moulds on single the fin heat exchanger tube.
Further; Aforesaid list props up fin heat exchanger tube side sway means for correcting; Wherein:, be respectively arranged with a guider that can single fin heat exchanger tube be imported smoothly draw-in groove in the fixed correction mould the forward and backward side of fixed correction mould along the traffic direction of single fin heat exchanger tube.
Further, aforesaid list props up fin heat exchanger tube side sway means for correcting, and wherein: the structure of said guider is: the guide roller of expansion bearing between two gripper shoes.
Through the enforcement of technique scheme, that the present invention has is simple to operate, and can carry out the advantage that linearity is proofreaied and correct to the heat exchange pipeline with side sway phenomenon at short notice.
Description of drawings
Fig. 1 props up the structural representation of fin heat exchanger tube side sway means for correcting for list of the present invention.
Fig. 2 is the A-A cross-sectional view of the fixed correction mould shown in Fig. 1.
The B-B cross-sectional view that Fig. 3 props up the fin heat exchanger tube for the list shown in Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is described further.
Like Fig. 1, Fig. 2, shown in Figure 3; Described list props up fin heat exchanger tube side sway means for correcting; Comprise: base 1; On base 1, be set with two fixed correction moulds linearly spaced apart 2,21, the same side of said fixed correction mould 2,21 offers the draw-in groove 3 that connects whole fixed correction mould respectively, and the shape of cross section of said draw-in groove 3 matches with the shape of cross section that list with single fin 5 props up fin heat exchanger tube 4; The shape of cross section that is draw-in groove 3 is the single circle that matches with heat exchanger tube 4, and semicircular bottom also is provided with the groove 31 that the list that holds on the heat exchanger tube 4 props up fin 5.At the base 1 of draw-in groove 3 one sides that are positioned at fixed correction mould 2,21 be set with a telescopic cylinder 6; The piston rod of said telescopic cylinder 6 is provided with movable straightening die 7, and the piston rod of said telescopic cylinder 6 stretches out and 7 pairs of lists of movable straightening die propped up on the fin heat exchanger tube 4 at fixed correction mould 2, position between 21 knock; In the present embodiment; Traffic direction along single fin heat exchanger tube 4; Front end at fixed correction mould 2 is provided with the guider in the draw-in groove 3 that can make single fin heat exchanger tube 4 smooth importing fixed correction moulds 2,21, and the structure of said guider is: the guide roller 9 of expansion bearing between two gripper shoes 8; Be provided with the guiders that can make 4 smooth draw-in groove 3 derivation from fixed correction mould 2,21 of single fin heat exchanger tube in the rear end of fixed correction mould 21; The structure of said guider is: the guide roller 91 of expansion bearing between two gripper shoes 81; Setting through guide roller 9,91; The workman can import fixed correction mould 2,21 with single fin heat exchanger tube 4 more smoothly or from fixed correction mould 2,21, derive, and has improved work efficiency of workers.
Operation principle of the present invention is following: when the timing that carries out that need prop up fin heat exchanger tube 4 to the list that the side sway phenomenon takes place; End with this single fin heat exchanger tube 4 is placed on the guide roller 9 earlier; Manual work pushes to single fin heat exchanger tube 4 in the fixed correction mould 2,21 then, and it is moved forward along the draw-in groove 3 in the fixed correction mould 2,21; Then again the position that has the side sway phenomenon on single the fin heat exchanger tube 4 is placed between fixed correction mould 2 and the fixed correction mould 21; Start telescopic cylinder 6 then; Movable straightening die 7 will knock at the side sway position to single fin heat exchanger tube 4 under the drive of telescopic cylinder 6, eliminate until the side sway phenomenon at side sway position.Through aforesaid operations, that the present invention has is simple to operate, can carry out the advantage that glacing flatness is proofreaied and correct to the heat exchanger tube with side sway phenomenon fast.
