Description

Technical Field

[0001] The present application relates to the technical field of refrigeration copper pipes, and particularly to a processing device for refrigeration copper pipes. Background Art

[0002] There are some metal copper pipes inside refrigeration equipment. Such metal copper pipes are an important part of the refrigeration pipeline. Before this, in order to facilitate the layout and installation of the copper pipes, it is also necessary to process the copper pipes, such as bending, welding, flaring and other processing procedures.

[0003] Among them, the flaring process is to form an expanded trumpet-shaped mouth at the end of the copper pipe, so that it can better fit the joint component during connection, ensuring the sealing performance at the connection. Good sealing performance can effectively prevent refrigerant leakage and maintain the pressure stability of the system. In addition, flaring the copper pipe also has the advantages of simplifying the installation process, reducing stress concentration and adapting to different specifications of fittings.

[0004] At present, in related copper pipe flaring equipment, generally workers place the copper pipe to be processed at the processing position, the flaring equipment fixes the copper pipe independently, and uses the method of rotating the expanding head to perform flaring processing. After the processing is completed, the worker removes the copper pipe and replaces it. However, in the above process, due to the small hardness and good ductility of the copper pipe, there is a certain frictional force between the expanding head and the copper pipe along its rotation direction during the feeding process of the expanding head. This frictional force easily causes the flared part to be skewed (twisted), and even torn, which increases the defective rate during the copper pipe processing, and there is a lot of manual participation and the operation steps are relatively cumbersome.

Detailed Description of the Embodiment

[0024] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application and should not be construed as limiting the present application.

[0025] The refrigeration copper tube processing device of the embodiment of the present application will be described below with reference to the accompanying drawings.

[0026] As Figures 1 - 4 shown, the refrigeration copper tube processing device of the embodiment of the present application may include: a frame 1, a transmission mechanism 2, multiple groups of fixture mechanisms 3, and a flaring mechanism 4.

[0027] Among them, both ends and the upper part of the frame 1 are arranged in an open structure.

[0028] It is understandable that both ends and the upper part of the frame 1 are arranged in an open structure, which is convenient for relevant technical personnel (such as workers) to perform steps such as feeding, flaring processing, and automatic discharging of copper tubes.

[0029] The transmission mechanism 2 is arranged on the frame 1, and the transmission mechanism 2 is used to drive the fixture mechanism 3 and the copper tube to be processed to move.

[0030] Multiple groups of fixture mechanisms 3 are respectively installed on the transmission mechanism 2. The fixture mechanism 3 includes two connecting seats 31, a fixing component 33, and two rotating components 32.

[0031] Among them, the two connecting seats 31 are respectively connected to the transmission mechanism 2, the two rotating components 32 are respectively installed on the corresponding connecting seats 31, and the rotating component 32 is used to connect the fixing component 33 to provide a turning force to the fixing component 33.

[0032] The fixing component 33 is arranged between the two rotating components 32, and the fixing component 33 is used to limit the copper tube to be processed at the end and inside thereof to fix the copper tube to be processed.

[0033] It is understandable that the fixing component 33 extends into the inside of the copper tube, which can increase the strength of the copper tube and avoid deformation of the copper tube during the processing.

[0034] In addition, the fixing component 33 is arranged vertically upward, which is convenient for relevant technical personnel to sleeved the copper tube outside it, thus facilitating the feeding of the copper tube.

[0035] The flaring mechanism 4 includes two groups of brackets 41, a driving component 42, and a flaring component 43.

[0036] Among them, the two groups of brackets 41 are symmetrically installed on the frame 1. The bracket 41 is used to support the driving component 42 and the flaring component 43. The driving component 42 is arranged on the two groups of brackets 41. The driving component 42 is used to drive the flaring component 43 to rotate at a preset angle. The flaring component 43 includes a fixed seat 431, a cylinder 432, and a flaring member 433. The flaring component 43 is used to perform flaring processing on the copper tube to be processed.

[0037] Among them, the fixed seat 431 is connected to the driving component 42, the cylinder 432 is installed on the fixed seat 431, the flaring member 433 is connected to the telescopic end of the cylinder 432. The cylinder 432 is used to pull the flaring member 433 away from the processed copper tube. The flaring member 433 is used to perform flaring processing on the copper tube and apply a force to the fixing component 33.

[0038] It should be noted that the connection between the cylinder 432 and the flaring member 433 described in this embodiment is a detachable connection method. When the flaring size of the copper tube changes, on the one hand, the relative position between the flaring member 433 and the copper tube can be changed, and on the other hand, the flaring member 433 can be replaced, thereby expanding the applicable range of this equipment.

[0039] In the embodiment of the present application, the external mains power supplies power to the transmission mechanism 2 and the flaring mechanism 4 in this equipment, thereby ensuring the normal operation of this equipment.

[0040] It should be noted that a control device (not shown in the figure) is also provided on the frame 1. The transmission mechanism 2 and the flaring mechanism 4 are respectively connected to the control device. Workers can input equipment operation data into it through the control panel on the control device to ensure that the operation data of the transmission mechanism 2 is adapted to the operation data of the flaring mechanism 4. The above specific operation data can be obtained according to the actual situation and will not be specifically limited here.

[0041] Specifically, in order to facilitate the installation of the copper tubes required in the refrigeration equipment, workers use this equipment to flare a batch of copper tubes.

[0042] First, the workers place the batch of copper tubes on the material rack and run this device. The transmission mechanism 2 drives the fixture mechanism 3 to move. The copper tube to be processed is picked up by a robotic arm or manually, and one end of the copper tube is sleeved outside the fixing member 33. The copper tube to be processed moves with the transmission mechanism 2. When the copper tube to be processed moves to a preset position (the preset position can be obtained through actual measurement, and this working condition can be obtained through a position sensor, and the position sensor is connected to the control device), the flaring mechanism 4 starts to operate, and the flaring assembly 43 starts to rotate.

[0043] After the flaring member 433 abuts against the pipe orifice of the copper tube to be processed, the flaring member 433 continues to rotate, and the copper tube to be processed starts to flip, and the flaring member 433 gradually enters the interior of the copper tube to be processed.

[0044] The end of the flaring member 433 first abuts against the fixing member 33, and the flaring member 433 exerts a force on the fixing member 33, and the fixing member 33 clamps and fixes it inside the copper tube to be processed, thereby simplifying the operation steps.

[0045] The flaring member 433 continues to enter the interior of the copper tube to be processed, the length of the flaring member 433 is compressed and reduced, and the flaring member 433 interacts with the pipe orifice of the copper tube. When the flaring member 433 and the copper tube are in a vertical state, the flaring process of the copper tube is completed, and the flaring assembly 43 and the copper tube interact linearly with each other, avoiding the situation of skewness (twisting) at the flared part of the copper tube and improving the yield rate during the copper tube processing.

[0046] Meanwhile, the cylinder 432 pulls the flaring member 433 upward. During the process of the length of the flaring member 433 resetting, the flaring member 433 can still exert a part of the force on the fixing member 33, so that the copper tube is clamped by the fixing member 33, ensuring that when the flaring member 433 disengages from the copper tube nozzle, the copper tube will not move with the flaring member 433, and the copper tube and the flaring member 433 can be quickly separated.

[0047] As the transmission mechanism 2 drives the copper tube to move, the flaring member 433 completely disengages from the nozzle of the copper tube. The driving assembly 42 drives the flaring assembly 43 to reset, and the fixing member 33 releases the clamping of the copper tube. When the transmission mechanism 2 drives the copper tube to turn, under the action of gravity, the copper tube automatically disengages from the fixing member 33 and enters the interior of the external collection device, reducing the manual participation. The next copper tube continues to repeat the above steps for flaring processing.

[0048] As a possible situation, in order to reduce the force between the flaring member 433 and the copper tube, a heating device (not shown in the figure) can be installed above the frame 1. The specific structure of the heating device has been disclosed in the prior art, so it will not be described in detail here. The heating device can increase the temperature of the copper tube nozzle, making the nozzle part easy to deform.

[0049] As another possible situation, in order to further reduce the force between the flaring member 433 and the copper tube, an oil spraying device (not shown in the figure) can be installed on the flaring mechanism 4. The specific structure of the oil spraying device has been disclosed in the prior art, so it will not be described in detail here. The oil spraying device can spray lubricating oil on the outside of the flaring member 433, thereby reducing the force between the flaring member 433 and the copper tube.

[0050] In an embodiment of the present application, as Figure 4 shown, the flaring member 433 includes a cylinder body 4331, a cone 4332, a spring 4333, a top plate 4334 and a pressure rod 4335.

[0051] Among them, the closed end of the cylinder body 4331 is connected to the telescopic end of the cylinder 432, one end of the cone 4332 is connected to the open end of the cylinder body 4331, and the cone 4332 is used to contact the nozzle of the copper tube to achieve the purpose of flaring.

[0052] The spring 4333 and the top plate 4334 are respectively arranged inside the cylinder body 4331. One end of the spring 4333 is connected to the inner wall of the cylinder body 4331, the other end of the spring 4333 is connected to the top plate 4334, one end of the pressure rod 4335 is connected to the top plate 4334, the other end of the pressure rod 4335 penetrates the cone 4332, and the pressure rod 4335 is slidably connected to the cone 4332.

[0053] Specifically, before the flaring process of the copper tube, the pressing rod 4335 first enters the interior of the copper tube to be processed. One end of the pressing rod 4335 abuts against the fixing component 33, and the fixing component 33 clamps the copper tube. Then, the cone 4332 enters the interior of the copper tube to be processed. At the same time, the pressing rod 4335 pushes the top plate 4334, and the spring 4333 is compressed. The cone 4332 performs the flaring process on the mouth of the copper tube.

[0054] When the flaring assembly 43 is vertically oriented towards the ground, the flaring process of the copper tube is completed. The air cylinder 432 pulls the cylinder body 4331 and the cone 4332 upward, and the spring 4333 resets. When the cone 4332 disengages from the mouth of the tube, there is still some acting force between the pressing rod 4335 and the fixing component 33. That is to say, when the cone 4332 disengages from the mouth of the tube, the copper tube is clamped by the fixing component 33, thus preventing the copper tube from moving with the flaring member 433.

[0055] After that, the pressing rod 4335 separates from the fixing component 33, and the copper tube stays on the fixing component 33 until the unloading is automatically completed.

[0056] As a possible situation, the diameter of the pressing rod 4335 is slightly smaller than the diameter of the copper tube to be processed. Before the cone 4332 enters the copper tube, the pressing rod 4335 enters the copper tube in advance, which can form a support inside the copper tube, thereby enhancing the strength of the copper tube and preventing the copper tube from deforming during the processing.

[0057] In an embodiment of the present application, as Figure 2 shown, the rotating component 32 includes a rod body 321, a torsion spring 322, and a base 323.

[0058] Among them, one end of the rod body 321 is rotatably connected to the connecting seat 31, the other end of the rod body 321 is connected to the base 323, one end of the torsion spring 322 is connected to the connecting seat 31, the torsion spring 322 is sleeved outside the rod body 321, and the other end of the torsion spring 322 is connected to the rod body 321.

[0059] Specifically, when the flaring assembly 43 toggles the copper tube and the copper tube drives the fixing component 33 to flip, the elastic potential energy of the torsion spring 322 increases. After the flaring assembly 43 separates from the copper tube, the torsion spring 322 can drive the fixing component 33 and the copper tube to reset, thus ensuring that the fixing component 33 is vertically upward during loading, and further facilitating the loading of the copper tube.

[0060] In an embodiment of the present application, as Figure 1 and Figure 2 shown, the fixing component 33 includes a telescopic rod 331, two plate bodies 332, and a plurality of second hinge rods 333.

[0061] Among them, the telescopic rod 331 is vertically installed on the base 323. Two plate bodies 332 are symmetrically arranged on both sides of the telescopic rod 331. A plurality of second hinge rods 333 are respectively arranged between the telescopic rod 331 and the plate bodies 332.

[0062] It should be noted that the telescopic rod 331 described in this embodiment includes a sleeve, a sleeve rod and a spring. The telescopic rod 331 can reset itself. Its specific connection structure has been disclosed in the prior art, so it will not be elaborated in detail here.

[0063] In addition, the two plate bodies 332 are of a square structure. When the plate bodies 332 contact the inner wall of the copper pipe, it is a line contact. The direct contact area between the two is small, the acting force is large, and the clamping effect is good.

[0064] Specifically, one end of the pressure rod 4335 abuts against the upper end of the telescopic rod 331, and the telescopic rod 331 deforms to drive the second hinge rod 333 to rotate. The two plate bodies 332 move away from each other, so as to clamp the copper pipe. After the fixing member 33 resets, under the action of the spring, the plate bodies 332 fit against the outer wall of the telescopic rod 331, so as to facilitate sleeving the copper pipe outside the fixing member 33.

[0065] In an embodiment of the present application, the bracket 41 includes a support plate 411, a bottom plate 412, two sliders 414, a plurality of first hinge rods 415 and an adjusting screw rod 416.

[0066] Among them, the support plate 411 is arranged above the frame 1. The bottom plate 412 is connected to the support plate 411. A guide groove 413 is opened on the bottom plate 412. The two sliders 414 are respectively slidably connected to the guide groove 413. A plurality of first hinge rods 415 are respectively arranged between the support plate 411 and the corresponding sliders 414. The adjusting screw rod 416 is arranged on the bottom plate 412. The adjusting screw rod 416 is threadedly connected to the two sliders 414.

[0067] Specifically, when the specification of the copper pipe changes (for example: the length changes or the inner diameter changes) or the size of the flaring needs to be changed, at this time, the relevant technical personnel can rotate the adjusting screw rod 416, the relative positions of the two sliders 414 change, and the first hinge rod 415 can change the distance between the bottom plate 412 and the support plate 411, and finally the position of the flaring assembly 43 changes.

[0068] During the rotation of the flaring assembly 43, the relative position between the flaring member 433 and the pipe orifice of the copper pipe changes, thereby expanding the applicable range of the equipment.

[0069] In an embodiment of the present application, as Figure 3 shown, the driving assembly 42 includes an electric push rod 421, a rack 422, a gear 423 and a support rod 424.

[0070] Among them, the electric push rod 421 is arranged on the support plate 411, the rack 422 is connected to the telescopic end of the electric push rod 421, the gear 423 is meshed and connected with the rack 422, the support rod 424 is rotatably connected to the two support plates 411, one end of the support rod 424 penetrates through one support plate 411, and one end of the support rod 424 is connected to the gear 423.

[0071] In an embodiment of the present application, as Figure 3 shown, a limiting groove 426 is opened on one support plate 411, a guide rod 425 is arranged on the rack 422, and the guide rod 425 is slidably arranged inside the limiting groove 426.

[0072] Specifically, during the operation of the driving assembly 42, the electric push rod 421 pulls the rack 422 to move, and the rack 422 drives the guide rod 425 to move inside the limiting groove 426, thereby ensuring the stability of the movement of the rack 422.

[0073] The rack 422 is meshed and connected with the gear 423, and the gear 423 drives the support rod 424 to rotate, thereby driving the flaring assembly 43 to rotate for flaring the copper pipe.

[0074] It should be noted that, referring to Figure 3 , the flaring assembly 43 is arranged horizontally with the ground. At this time, it is the initial position of the flaring assembly 43. The driving assembly 42 can drive the flaring assembly 43 to rotate by 90° - 135°. On the premise of ensuring that the flaring assembly 43 can smoothly disengage from the copper pipe, the specific rotation angle can be determined according to the actual situation.

[0075] In an embodiment of the present application, as Figure 1 shown, the transmission mechanism 2 includes a plurality of sprockets 21, a plurality of connecting rods 22, two chain tracks 23 and a driving device 24.

[0076] Among them, the plurality of sprockets 21 are rotatably connected to the inner wall of the frame 1, the plurality of connecting rods 22 are respectively arranged between the corresponding two sprockets 21, the two chain tracks 23 are respectively wound around the outside of the corresponding sprockets 21, the chain track 23 is connected to the connecting seat 31, the driving device 24 is arranged outside the frame 1, one end of a connecting rod 22 penetrates through the inner wall of the frame 1, and one end of a connecting rod 22 is connected to the output shaft of the driving device 24.

[0077] It should be noted that during the process of the transmission mechanism 2 driving the fixture mechanism 3 to move, the fixture mechanism 3 will not interfere with the connecting rod 22, thereby ensuring the normal operation of the equipment.

[0078] As a possible situation, in order to avoid the loosening of the crawler 23 after long-term use, a tensioning mechanism (not shown in the figure) can be installed between the transmission mechanism 2 and the frame 1. The specific structure of the tensioning mechanism has been disclosed in the prior art, so it will not be elaborated in detail here.

[0079] In summary, for the refrigeration copper tube processing equipment of the embodiment of the present application, the driving component drives the flaring component to rotate, the transmission mechanism drives the copper tube to be processed to move, the flaring component approaches the pipe orifice of the copper tube, and then inserts into the interior of the copper tube. The flaring component and the copper tube interact linearly with each other, avoiding the skew (twist) of the flared part of the copper tube, improving the yield rate during the copper tube processing. In the copper tube flaring processing procedure, the flaring component can also press the fixing part to clamp the copper tube, simplifying the operation steps. As the transmission mechanism drives the movement of the copper tube, under the action of gravity, the processed copper tube can achieve automatic unloading, reducing the participation of labor.
