Description

Technical Field

[0001] This utility model relates to the field of heat exchanger tube processing technology, and in particular to a heat exchanger tube bending guide calibration fixture. Background Technology

[0002] As a highly efficient heat transfer device, heat exchange tubes have been widely used in many fields such as industrial production and energy utilization due to their unique structure and excellent performance. A bending guide device is a device or structure specifically designed to control the movement or positioning of an object along a preset bending path. Especially in the field of heat exchange tube processing technology, the heat exchange tube bending guide calibration fixture can guide the heat exchange tube to pass through the bending area stably, smoothly and safely, thereby obtaining the ideal bending effect.

[0003] Existing bending guide devices can only bend heat exchange tubes to a single radius. When different bending radii are required, different bending guide devices need to be replaced, which increases the trouble of heat exchange tube processing and affects the efficiency of heat exchange tube bending. Moreover, existing bending guide devices cannot heat the heat exchange tubes during processing. During bending, the heat exchange tubes are often at room temperature, with low plasticity, which makes them prone to wrinkles, breakage, etc., affecting the bending results. Furthermore, they cannot dissipate heat from the wheel assembly, which may cause damage to the wheel assembly due to excessive temperature.

[0004] Therefore, those skilled in the art have provided a heat exchanger tube bending guide calibration fixture to solve the problems mentioned in the background art. Utility Model Content

Through the cooperation of the sliding mechanism and the wheel module, the heat exchanger tube can be processed to multiple degrees of bending, reducing the trouble of changing different devices and improving processing efficiency. The heating and heat dissipation mechanisms enable the heat exchanger tube to have better plasticity during bending, improving the quality of bending processing. The heat dissipation mechanism can prevent the wheel module from malfunctioning due to excessive temperature.

[0010] Furthermore, the outer wall of the shroud is tightly fitted to the inner wall of the ventilation hole; The above technical solution allows air to enter the ventilation holes more effectively.

[0011] Furthermore, a pipe bending mechanism is fixedly connected to one side of the outer wall of the wheel module, and the lower surface of the pipe bending mechanism is fixedly connected to the upper surface of the mounting platform.

A pipe feeding mechanism 6 is fixedly connected to the middle of the upper surface of the machine body 7.

[0021] Working principle: The heat exchange tube 5 is installed inside the tube feeding mechanism 6. The machine is started, and the tube feeding mechanism 6 conveys the heat exchange tube 5 forward. The resistance coil 4 is activated; when the heat exchange tube 5 passes through the resistance coil 4, electromagnetic induction converts electrical energy into heat energy, thus heating the heat exchange tube 5. The bending mechanism 8, in conjunction with the wheel module 1, clamps the heated heat exchange tube 5. Activating the bending mechanism 8 causes the heat exchange tube 5 to bend around the wheel module 1. The heat dissipation mechanism 2 drives the first motor 206, which in turn rotates the fan blades 207, drawing air in through the air inlet 204. The ventilation holes 101 and heat-conducting plate 106 facilitate better heat conduction. The fan shroud 201 allows the air to dissipate heat more effectively through the ventilation holes 101, thus achieving efficient heat dissipation. The wheel module 1 dissipates heat through the ventilation slots 108 and small ventilation holes 107, which cool the area around the heat exchange tube 5. When different bending radii are required, the motor 302 is started to rotate the first threaded rod 303, which then moves the sliding plate 305 along the direction of the first guide block 301 via the first slider 311, thereby adjusting the wheel module 1 in the up and down direction. The motor 302 drives the second threaded rod 309 to rotate, which then moves the mounting base 307 along the direction of the second guide block 310 via the second slider 306, thereby adjusting the wheel module 1 in the left and right direction. This allows the wheel module 1 to be adjusted to better cooperate with the bending mechanism 8, thereby clamping the heat exchange tube 5 and meeting the requirements of different bending processes.
