Description
Technical Field
[0001] This invention relates to the field of molding equipment technology, specifically to a device for forming and processing spiral parts inside heat exchange tubes. Background Technology
[0002] Heat exchange tubes are one of the components of a heat exchanger. They are placed inside the shell and used for the exchange of heat between two media. They have high thermal conductivity and good isothermal properties. Some heat exchange tubes have a spiral component inside, which acts as a flow obstruction. The spiral component is processed by a spiral forming machine.
[0003] However, existing spiral forming and processing equipment has some problems in use. In use, existing spiral forming and processing equipment usually only performs forming processing on spiral blanks. However, spirals need to be adapted to heat exchange tubes for use. If the spiral is formed directly, it may result in a mismatch between the formed spiral and the inner wall of the heat exchange tube or gaps between them, which will affect the subsequent use of the heat exchange tube. At the same time, it is not convenient to clamp and limit the heat exchange tubes of different sizes, nor is it convenient to clamp, limit and process spiral blanks of different sizes, thus reducing the applicability of the equipment.

[0017] Working principle: When the device starts working, the heat exchange tube is first placed at the center of the three limiting rings 22. The heat exchange tube drives the second clamping plate 26 to move, the second clamping plate 26 drives the movable rod 24 to move, the movable rod 24 drives the fixed plate 23 to move, the second clamping plate 26 drives the second spring 25 to compress, and the second clamping plate 26 clamps and limits the heat exchange tube through the second spring 25. The second motor 30 is started, the second motor 30 drives the double-threaded rod 31 to rotate, the double-threaded rod 31 drives the movable block 29 to move, the movable block 29 drives the support column 28 to move, and the support column 28 drives the adjacent limiting rings 22 to move. The limiting rings 22 on the left and right sides can accommodate different lengths of heat exchange tubes. After the heat exchange tube is clamped and limited, the spiral blank is passed through the heat exchange tube. The right side of the spiral blank moves into the N-type plate 17. By rotating the first threaded rod 15, the N-type plate 17 can be moved up and down. The first clamping plate 18 inside the N-type plate 17 clamps the right side of the spiral blank with the cooperation of the crossbar 19, the first spring 20 and the push plate 21. Then, the nut 35 is rotated, moving the nut 35 to the surface of the second threaded rod 34 and away from the moving plate 40. The adjusting plate 33 can then move up and down. When the two third clamping plates 39 inside the adjusting plate 33 move to the left side of the spiral blank, the nut 35 is rotated again, bringing the nut 35 close to the moving plate 40 and tightening it, thereby adjusting the plate. 33 is limited, and cylinder 37 is activated. Cylinder 37 clamps the left side of the spiral blank through fixing plate 38 and third clamping plate 39. Then, the first motor 8 is activated, which drives transmission rod 9 to rotate. Transmission rod 9 drives three-jaw chuck 10 to rotate. Three-jaw chuck 10 drives fixing rod 13 to rotate through fixing tube 11 and bolt 12. Fixing rod 13 drives fixing block 14, first threaded rod 15 and N-type plate 17 to rotate. N-type plate 17, with the cooperation of first clamping plate 18, drives spiral blank to rotate, thereby enabling spiral part forming. If it is necessary to shorten the length of spiral part, adjusting plate 42 is moved upward. Adjusting plate 42 drives second insert rod 44 upward. The second insert rod 44 is moved, causing the fourth spring 43 to stretch and move the second insert rod 44 out of the base plate 1. Then, the moving plate 40 is adjusted to the right. The moving plate 40 causes the moving block 45 to move, and the moving plate 40 causes the adjusting plate 33 to move to the right. The adjusting plate 33 causes the spiral component to move to the right through the third clamping plate 39. If it is necessary to extend the length of the spiral component, the first insert rod 7 is moved and removed from the base plate 1. The movable plate 2 is then moved to the right. The movable plate 2 causes the limiting plate 5 and the slider 6 to move to the right. The movable plate 2 causes the vertical plate 3 to move to the right. The vertical plate 3 causes the three-jaw chuck 10 to move to the right. The three-jaw chuck 10 causes the spiral component to move to the right through the first clamping plate 18.
