Description

[0002] In order to improve the heat exchange efficiency, a fin strip is usually wound around the outer wall of a steel tube to obtain a fin tube, thereby increasing the heat dissipation area of ​​the base tube, thereby achieving the purpose of improving the heat exchange efficiency of the base tube.

[0003] According to different processing techniques, fin tubes can be divided into cold-wound fin tubes, high-frequency welded fin tubes, hot-rolled fin tubes, expanded fin tubes, etc. Among them, cold-wound fin tubes are made by winding steel strips on the outside of the base tube, which has higher heat transfer performance and lower cost.

[0004] At present, there are circular cold-wound fin tubes and elliptical cold-wound fin tubes on the market. Compared with circular cold-wound fin tubes, elliptical cold-wound fin tubes have the characteristics of small windward resistance, large heat contact surface and small leeward vortex area. Therefore, the heat transfer coefficient of elliptical cold-wound fin tubes is 3 to 7 times higher than that of circular fin tubes, and they are becoming more and more popular among users.

[0046] By selecting a matching guide tube 14 according to the elliptical steel tubes with different cross-sectional sizes, one device can be suitable for elliptical steel tubes with different cross-sectional sizes, saving costs and floor space. Specifically, the elliptical steel tube is inserted into the interior of the set guide tube 14, and the elliptical steel tube is limited in a single direction. Under the action of the clamping wheel 12, the elliptical steel tube drives the guide tube 14 and the turntable 13 to rotate on the turntable fixing seat 31.

[0049] The motor 24 rotates and then the T-type reducer 25 cooperates to make the lead screw 1 26 and the lead screw 2 28 rotate synchronously. The rotation of the lead screw 1 26 drives the slider 3 27 to slide the fixed plate 1 30 on the table 2 under the limiting action of the strip hole 1; the rotation of the lead screw 2 28 drives the slider 4 29 to move the fixed plate 2 16 on the table 2 under the limiting action of the strip hole 2, thereby realizing the synchronous sliding of the fixed plate 1 30 and the fixed plate 2 16.

[0050] The screw-driven elliptical steel tube winding fin tube forming device provided by the utility model has the following working principles: when in use, the elliptical steel tube is passed through the guide tube 14, one end of the fin belt is pulled through the guide wheel 23, and passes through the groove 1 of the guide plate 10 and the groove 2 on the pressure wheel 12 from top to bottom in turn, and is initially guided and wound and fixed on the outer wall of the end of the elliptical steel tube through the pressure wheel 12.

The telescopic member 8 pushes the extrusion wheel shaft fixing seat 11 on the support seat 7 and the pressure wheel 12 to The fin band and the elliptical steel tube are pressed tightly, and at the same time, the pressing wheel 12 on the extrusion wheel shaft fixing seat 11 rolls the fin band and wraps the fin band around the outer wall of the elliptical steel tube. At the same time, the feeding speed and rotation speed of the elliptical steel tube are controlled by the external feeding auxiliary device to complete the forming process of the elliptical steel tube winding the fin tube. It should be noted that when it is necessary to process elliptical steel tubes with different cross-sectional sizes, it is only necessary to stop the machine and replace the corresponding guide tube 14, and adjust the processing parameters on the external electronic control auxiliary device, and repeat the above steps, thereby realizing "one machine with multiple modes", saving the cost of purchasing the device and the area occupied by the device, and at the same time, it can realize rapid mold change to improve production efficiency.
