[0002] Heat exchange tubes are a type of heat-conducting component and are mainly installed in heat exchangers. For example, heat exchange tubes are installed in air conditioners, refrigerators and other equipment. For example, the heat exchange copper tubes used can quickly transfer heat due to the high thermal conductivity of copper and are widely used in various industrial and civil fields.

[0003] When in use, the heat exchange tube is installed inside the heat exchanger. According to the different needs of different heat exchangers, heat exchange tubes of different shapes need to be installed. The shape of the heat exchange tube needs to be shaped and processed. For example, a bending machine is required to bend the material tube. When in use, a bending component that can move in a circular motion applies a thrust to the material tube, causing the tube to bend and deform in the required area, making it convenient to install the heat exchange tube inside a limited space. However, different heat exchangers may require heat exchange tubes of different thicknesses and diameters. Different bending components need to be replaced for different heat exchange tubes for bending and shaping. The need to replace the bending components is more troublesome to use. For this reason, we provide a pre-forming device for heat exchange tube processing to solve the above problems. Utility Model Content

[0004] In order to solve the above problems, the present invention provides a pre-forming device for processing heat exchange tubes to solve the above problems. The specific technical solution is as follows:

[0005] A pre-forming device for processing heat exchange tubes includes an operating table, a driving component is installed on the outside of the operating table, a fixed plate is installed above the driving component, a control component is installed on the outside of the driving component, a fixed frame is installed on the outside of the control component, a limiting groove is provided inside the fixed frame, the inner wall of the limiting groove is slidably connected to multiple groups of fixed blocks, one side of the multiple groups of fixed blocks is respectively fixedly installed with an upper pressure plate and a lower pressure plate, a fixing groove is provided inside the lower pressure plate, a double-headed screw is rotatably connected inside the limiting groove, and the outer surface of the double-headed screw is threadedly connected to multiple groups of moving blocks.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The pre-forming device for processing heat exchange tubes cooperates between the upper pressing plate, the lower pressing plate and the double-headed screw. When working, the double-headed screw can control the sliding of the moving block inside the limit groove, and the distance between the upper pressing plate and the lower pressing plate can be controlled. When the spacing between the upper pressing plate and the lower pressing plate changes, the angle depth between the two can be adjusted. The corresponding parameters can be adjusted when bending and shaping heat exchange copper tubes of different sizes. It is very convenient to use and there is no need to disassemble the entire bending component. The corresponding bending component parameters can be adjusted for heat exchange copper tubes with different bending requirements, thereby realizing the adjustment of the bending component parameters and facilitating use.

When the insert rod enters the interior of the connecting block, the connecting block can be fixed, and the upper pressure plate or the lower pressure plate can be fixed to the outside of the moving block. When the limit rod does not contact the interior of the fixing hole, the limit rod moves under the pressure of the inner wall of the limit groove and drives the insert rod to move. At this time, the insert rod automatically moves toward the interior of the connecting block. When the limit rod moves to the position of the fixing hole, the spring can push the limit rod into the interior of the fixing hole. At this time, the connecting block is out of contact with the insert rod, and the upper and lower pressure plates can be quickly replaced, which is convenient for maintenance.

The outer side of the copper tube at the position of the fixed disk 3 can be pressed and fixed by the fixing component 14, so that the bending component can be conveniently bent and formed.

[0022] A control component 4 is installed on the outside of the driving component 2, and a fixed frame 5 is installed on the outside of the control component 4. The control component 4 includes components such as an electric push rod and a slide rail. When in use, it can control the movement of the fixed frame 5 and can control the fixed frame 5 to move to the position of the fixed disk 3 to clamp the outside of the copper tube.

[0023] A limiting groove 6 is provided inside the fixing frame 5, and the inner wall of the limiting groove 6 is slidably connected to multiple groups of fixing blocks 7. An upper pressure plate 8 and a lower pressure plate 9 are fixedly installed on one side of the multiple groups of fixing blocks 7. The outer sides of the upper pressure plate 8 and the lower pressure plate 9 can be limited by the multiple groups of fixing blocks 7. The lateral contact between the fixing blocks 7 and the limiting groove 6 can also increase the stability of the upper pressure plate 8 and the lower pressure plate 9 when resisting deflection. The upper pressure plate 8 and the lower pressure plate 9 are both wedge-shaped mechanisms, which are arranged diagonally. The position of the top angle of the two can be adjusted. By adjusting the depth of the angle between the two, the copper tubes of different diameters can be adapted for bending and shaping.

[0024] A fixing groove 10 is provided inside the lower pressing plate 9, and the outer surface of the upper pressing plate 8 is slidably connected to the inside of the fixing groove 10. When the upper pressing plate 8 moves downward, it can enter the inside of the fixing groove 10. At this time, the angle depth adjustment between the upper pressing plate 8 and the lower pressing plate 9 is more convenient, which is convenient for bending copper tubes of different diameters.

[0025] The internal rotation of the limit groove 6 is connected with a double-headed screw 11, and the upper surface of the fixed frame 5 is fixedly installed with a control motor 15. One end of the control motor 15 is fixedly installed with one end of the double-headed screw 11. The double-headed screw 11 can be controlled to rotate by controlling the motor 15. The outer surface of the double-headed screw 11 is threadedly connected to multiple groups of moving blocks 12. The outer surface of the moving block 12 is slidingly connected to the inner wall of the limit groove 6. One side of the moving block 12 is slidingly connected to one side of the fixed block 7. The multiple groups of moving blocks 12 move in the opposite direction under the control of the double-headed screw 11.

[0026] A connecting block 16 is fixedly installed on one side of the fixed block 7. The outer surface of the connecting block 16 is slidably connected to the inside of the moving block 12. A mounting groove is provided inside the moving block 12. After the connecting block 16 is placed into the mounting groove, the connecting block 16 can be limited. The inside of the moving block 12 is slidably connected with an insertion rod 17. The outer surface of the insertion rod 17 is slidably connected to the inside of the connecting block 16. After the insertion rod 17 enters the inside of the connecting block 16, the position of the connecting block 16 can be limited, which can further fix the upper pressure plate 8 and the lower pressure plate 9. When the control insertion rod 17 is out of contact with the connecting block 16, the connecting block 16 can be removed. At this time, the upper pressure plate 8 and the lower pressure plate 9 can be quickly replaced.

[0027] The outside of the insertion rod 17 is covered with a spring 18, one end of the spring 18 is fixedly installed on the inner wall of the moving block 12, and one end of the spring 18 is fixedly installed with a limiting rod 19, one end of the limiting rod 19 is fixedly installed on one end of the insertion rod 17, the outer surface of the limiting rod 19 is slidingly connected to the inside of the moving block 12, and the outer surface of the limiting rod 19 is slidingly connected to the inner wall of the limiting groove 6. The spring 18 can control the limiting rod 19 to move to the outside of the moving block 12. When the outside of the limiting rod 19 is not squeezed, the insertion rod 17 can follow the limiting rod 19 to move to the outside of the moving block 12. At this time, the connecting block 16 can be removed. One end of the limiting rod 19 is a wedge-shaped structure, which can move toward the inside of the connecting block 16 when squeezed from above or below.

[0028] A fixing hole 20 is provided inside the fixing frame 5, and the fixing holes 20 are provided in two groups and are arranged symmetrically. The outer surface of the insertion rod 17 is slidably connected to the inside of the fixing hole 20. The moving position of the limit rod 19 can be controlled through the fixing hole 20. When the limit rod 19 enters the position of the fixing hole 20, the insertion rod 17 is disengaged from the connecting block 16. At this time, the upper pressure plate 8 and the lower pressure plate 9 can be quickly replaced. When the moving block 12 slides inside the limiting groove 6, the inclined surface of one end of the limiting rod 19 will be squeezed. At this time, the limiting rod 19 will enter the interior of the moving block 12 and drive the insertion rod 17 to move, which can automatically fix the connecting block 16, and is very convenient to use and replace.
