Description

Technical Field

[0001] The present invention relates to the technical field of heat exchanger production, specifically a tube winding machine. Background Art

[0002] During the manufacturing process of heat exchangers, the tube winding process is one of the key processes. The purpose is to tightly and evenly wind heat exchange tubes (usually copper tubes, steel tubes or other metal tubes) around the main tube (shell) of the heat exchanger to form an efficient heat exchange structure. At present, the tube winding process is mainly manual winding. That is, workers manually pull the heat exchange tubes from the coil and wind them around the axis of the main tube of the heat exchanger one by one. At the same time, simple tools (such as manual turntables or jigs) are needed to assist in fixing. However, in this way, it is necessary to maintain a uniform pitch and tension. Workers need to walk back and forth, adjust repeatedly, and perform high-intensity manual operations, resulting in extremely low production efficiency. The winding time for a single heat exchanger may be as long as several hours. In addition, during manual operation, workers need to be in close contact with the high-speed rotating main tube of the heat exchanger or the heat exchange tubes with large tension, there are safety hazards such as pinching and scratching. In addition, the metal tubes may suddenly bounce due to stress release during the winding process, causing personal injuries. In addition, due to the large differences in the length and diameter of the main tubes of heat exchangers, traditional fixing devices often cannot flexibly adapt to workpieces of different specifications, further restricting the versatility and efficiency of production.

Further optimized, in order to ensure the stable movement of the pipe feeding trolley 600, a track can be laid, and the pulleys 605 are located on the track, so that the pipe feeding trolley 600 moves linearly on the track;

[0053] When performing the tube winding work through the above-mentioned tube winding machine, one end of the main tube of the heat exchanger can be fixedly connected to the front clamping member 202, and the other end is fixedly connected to the rear clamping member. Then, the heat exchange tube is output from the disk 601, and one end of the heat exchange tube is fixedly connected to the main tube of the heat exchanger by welding. The driving member 202 drives the front clamping member 202 to rotate, so that the main tube of the heat exchanger rotates. At the same time, the tube feeding trolley 600 moves linearly along the axis direction of the main tube of the heat exchanger, so that the heat exchange tube can be wound around the main tube of the heat exchanger to complete the production of the heat exchanger. In addition, by rotating the operation panel 310, the ball screw 306 can be rotated, so that the adjustment table 305 can move linearly on the slide rail base 307, thereby adjusting the distance between the rear clamping member and the front clamping member 202 to meet the use requirements of the main tubes of heat exchangers with different lengths.
