Technical Field

[0001] This application relates to the technical field of evaporator manufacturing, and in particular to a novel end-flaring device for evaporator finned tubes. Background Technology

[0002] Evaporation is a physical process in which a liquid transforms into a gas. Generally speaking, an evaporator is an object that transforms a liquid substance into a gas.

[0003] Evaporator fins are made up of several fins connected by finned tubes. The ends of the finned tubes need to be flared in order to connect with the external tube body. In the existing technology, this is generally done by a flaring machine. Flaring machines need to be customized according to different tube diameters, which results in high purchase costs.

[0004] Therefore, in order to save costs, our company has developed a flaring device that can process pipes of different diameters. Utility Model Content

The rotating head is coaxially arranged with the pneumatic three-jaw chuck.

[0007] The rotating head includes an integrally formed connecting section, a balancing body, and a flared section. The flared section is a square block with rounded corners on both sides of the end away from the balancing body, and chamfers are provided at the edges of the square block.

[0008] The jaws of the pneumatic three-jaw chuck have arc-shaped ends, and a protective layer is provided inside the arc-shaped surfaces.

[0009] The base is provided with a groove corresponding to the position of the cylinder, and guide grooves are symmetrically provided on the top of the groove. The stop block is matched and disposed in the guide groove.

[0017] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0018] This application discloses a novel end-flaring device for evaporator finned tubes, referring to... Figure 1-3The system includes a base 1, a finned tube clamping and positioning mechanism 2, and a flaring mechanism 3. Both the finned tube clamping and positioning mechanism 2 and the flaring mechanism 3 are mounted on the base 1. The finned tube clamping and positioning mechanism 2 includes a pneumatic three-jaw chuck 21, a regulating valve 22, a cylinder 23, and a stop block 24. Both the pneumatic three-jaw chuck 21 and the regulating valve 22 are fixed on the base 1. The regulating valve 22 is connected to the pneumatic three-jaw chuck 21. The cylinder 23 is vertically mounted inside the base 1. The stop block 24 is vertically movably mounted on the base 1. The output end of the cylinder 23 is fixed to the stop block 24. The flaring mechanism 3 includes a servo linear guide slide 31, a mounting bracket 32, a motor 33, a coupling 34, and a rotating head 35. The servo linear guide slide 31 is fixed on the base 1, the mounting bracket 32 ​​is horizontally fixed on the slide of the servo linear guide slide 31, the motor 33 is fixed on the mounting bracket 32, and the rotating head 35 is connected to the output shaft of the motor 33 through the coupling 34. The rotating head 35 is coaxially arranged with the pneumatic three-jaw chuck 21. The rotating head 35 includes an integrally formed connecting section 351, a balancing body 352, and a flared portion 353. The flared portion 353 is a square block, and the ends away from the balancing body 352 have rounded corners on both sides. The edges of the square block are chamfered.

[0019] The jaws of the pneumatic three-jaw chuck 21 have arc-shaped ends, and a protective layer is provided inside the arc-shaped surface.

[0020] Reference Figure 1 The base 1 has a groove 11 corresponding to the position of the cylinder 23. The top of the groove 11 has a guide groove 12 symmetrically arranged. The stop block 24 is matched and arranged in the guide groove 12. The base 1 has a slide rail 13 symmetrically fixed on it. The mounting bracket 32 ​​is slidably connected to the slide rail 13.

[0021] Reference Figure 1 To ensure the smooth rotation of the rotating head 35, a bearing seat 4 is also fixed on the mounting bracket 32. The coupling 34 is rotatably connected in the bearing seat 4, and the rotating head 35 is detachably fixed on the coupling 34.

[0022] The implementation principle of the novel end-flaring device for evaporator finned tubes in this application is as follows: In use, the operator only needs to insert the finned tube into the pneumatic three-jaw chuck 21, with the end of the finned tube abutting against the stop block 24. Then, the pneumatic three-jaw chuck 21 works to center and clamp the finned tube, and the cylinder 23 drives the stop block 24 to move downward, leaving working space for the flaring mechanism 3. The servo linear guide slide 31 drives the motor 33 to move to one side of the finned tube. The rounded corner of the flaring part 353 on the rotating head 35 is first inserted into the finned tube. Then, the motor 33 drives the rotating head 35 to rotate at high speed, and the servo linear guide slide 31 continuously pushes the rotating head 35 into the finned tube, thereby completing the flaring work of the finned tube. The flaring effect is good and the efficiency is high. The pneumatic three-jaw chuck 21 is connected to the regulating valve 22, which can adjust the clamping size of the pneumatic three-jaw chuck 21 to adapt to the use of finned tubes of different diameters.

[0023] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
