The invention relates to a rolling device for a spiral heat exchange pipe core in a heat exchanger, and solves the technical problems of low accuracy, inconvenience in use and low production efficiency of an existing rolling device for a spiral heat exchange pipe. The rolling device for the spiral heat exchange pipe core in the heat exchanger comprises a machine body, a roller, a main shaft speedreduction servo motor, a feeding servo motor, a screw rod, a nut seat, a compression roller frame base, a compression roller frame, an air cylinder, a compression roller, two guide rails, a touch control screen and a main controller. Two ends of the roller are connected with the machine body through bearing seats; the main shaft speed reduction servo motor is connected with one end of the roller through a transmission mechanism; two ends of the screw rod are connected with the machine body through bearing seats; an output shaft of the feeding servo motor is connected with the screw rod througha transmission mechanism; the nut seat is connected with the screw rod; the compression roller frame base is fixedly connected with the nut seat; the compression roller frame is connected with the compression roller frame base; the compression roller is connected with the compression roller frame; the air cylinder is connected between the compression roller frame base and the compression roller frame; and the two guide rails are connected onto the machine body side by side. The rolling device for the spiral heat exchange pipe core in the heat exchanger provided by the invention is widely applied to rolling the spiral heat exchange pipe.
Description
technical field [0001] The invention relates to the technical field of helically wound tube heat exchangers, in particular to a rolling device for a helical heat exchange tube core in a heat exchanger. Background technique [0002] The spiral thread tube heat exchanger consists of two parts: core and shell. The core is mainly composed of spiral heat exchange tubes. The shell is composed of cylinder and head. The upper and lower heads have two openings. Referring to the Chinese utility model patent with the authorized announcement number CN204866968U, the spiral heat exchange tube is processed by a tube winding machine. The existing tube winding machine has technical defects that cannot accurately control the shape of the helix. In addition, there is a problem with the spiral stainless steel The calculation of the number of layers and rolling diameter of the tube is cumbersome, inconvenient to use and low in production efficiency. Contents of the invention [0003] The pre...
