Product description: 02 The H type fin tube automatic welding machine developed by our company includes a base and two sets of brackets installed on the base. It also includes two sets of automatic fin discharging silos, two sets of feeding cylinders, two sets of unloading channels, two sets of horizontal push cylinders, and two sets of electrode clamping mechanisms. 02.1. The new fin tube welding process is adopted, and the contact of the fin welding part adopts multiple zigzag shapes, so that the welding is firm, the welding formation is uniform and smooth, the surface is smooth, no slag inclusion pore welding tumor, and the welding transmittance reaches 97%. 02. The welding part adopts multiple zigzag methods, which is equivalent to reducing the local stiffness of the fin tube, thereby reducing the amount of compression plastic deformation generated during the welding process, reducing the longitudinal residual tensile stress near the weld, and greatly reducing the residual compressive stress borne by the fins far from the weld part, so the amount of wave deformation of the fin is significantly reduced. 023, the welding permeability is 97%, the weld surface is uniform and smooth without welding tumors, and the expansion of the heating surface can increase the heat transfer coefficient. On the other hand, the extended heating surface unit has a self-cleaning function, which can slow down the deposition, blockage and wear of smoke and dust on the heated surface, especially slowing down the wear can ensure the reasonable service life of the heated surface. Product features: 02 The punched and sheared fins are placed into the fin automatic discharging bin by manual code, and the feeding cylinder realizes automatic discharging. At the same time, the steel pipe is conveyed to the welding position, and the horizontal push cylinder pushes the electrode clamping mechanism to realize automatic welding. The electrode clamping mechanism is a key part of the welding machine. The electrodes on both sides are equipped with material receiving and pneumatic positioning mechanisms. The fins automatically enter the welding position, clamp the welding, and realize the welding of the fins on both sides and the steel pipe. The welding is complete, the clamp is loosened, the fin tube is manually removed, and the steel pipe moves forward. The parallel automatic welding of steel pipes and fins can meet the quality and efficiency requirements of fin tube welding well. 02 The fin tube is a reinforced heat exchange element arranged at the tail of the system flue to recover exhaust waste heat from power plant boilers, industrial boilers, industrial kilns, ship power units, etc., to effectively improve the fuel utilization rate. 02 In terms of structural design, the double H type finned tube adopts a separate structure for the easy ash formation part of the tube, which overcomes the shortcomings of easy ash accumulation, dust blocking, and gas resistance of the spiral sheet tube, and is an improved product of the spiral fin tube. In addition, the ribs of the fin tube form a cantilever beam structure. Under the action of pulsed airflow, the ribs vibrate, which is more favorable for ash removal. 02 Double H-type fin tubes, on the one hand, the extended heating surface can increase the heat transfer coefficient, and on the other hand, the extended heating surface unit has a self-cleaning function, which can slow down the deposition, blockage and wear of smoke and dust on the heating surface, especially the wear reduction can ensure the reasonable service life of the heating surface, and is the basis for the safe and economical operation of the waste heat boiler. Product advantages: 02 At present, the main production method of fin tubes is argon arc welding or electric welding. The fins are welded to the outside of the center steel pipe by simultaneous or multiple welding methods. Steel pipes and fins will experience thermal stress deformation during welding. This deformation cannot be overcome during argon arc welding or electric welding. The quality cannot be guaranteed, the yield is low, and the manual welding form causes the fin tube production to be slow and does not meet the requirements of mass production. In order to solve the above problems, our company specially designed and produced an automatic H type fin tube welding machine for double H type fin tube welding. The utility model has the advantages of simple structure, convenient operation, accurate control, high production efficiency, simultaneous welding of two fins, small wave deformation of the fins, stable welding quality, high yield, good market prospect, and higher profit.
