[0002] Aluminum tubes are widely used in automotive air conditioning systems, refrigeration systems, heat exchangers, building decoration, and industrial fluid transportation due to their lightweight, corrosion resistance, and good thermal conductivity. During the production process, the tube body needs to be extruded to improve the quality of the finished aluminum tube.

[0003] Existing continuous extrusion forming apparatuses for aluminum tubes typically feature rotating clamps for gripping the aluminum tubes. After the clamps hold the tubes, a continuous extrusion mechanism continuously extrudes the tubes to complete the extrusion forming process.

[0015] The continuous extrusion molding apparatus and method for aluminum tubes of the present invention have the following advantages over the prior art: (1) The continuous extrusion forming device for aluminum tube body of this application uses a clamp to insert aluminum tube for initial connection. The clamp is rotatable, so when feeding aluminum tube to be extruded, the clamp can be adjusted to face outwards, which facilitates the insertion connection of aluminum tube. A clamping plate is slidably provided on the inner side of the first insertion. After the aluminum tube is inserted into the first insertion, the clamping plate can be adjusted to move outwards and abut against the inner wall of the aluminum tube. Through friction, the insertion stability between the aluminum tube and the first insertion is improved. A bracket is provided to support the aluminum tube from below to improve the connection stability of the aluminum tube. An end baffle is provided that can be rotated to be located inside the rectangular assembly groove so that the end baffle does not obstruct the flow of the material. The proper insertion of the aluminum tube facilitates its connection. A first spring allows the end baffle to rotate to its reset position after the aluminum tube is fully inserted, preventing it from accidentally falling from the bracket's end during the adjustment of the clamping mechanism. The drive unit is slidably positioned, allowing the drive head to slide and insert the aluminum tube after loading. Through compression, the connection is completed. Furthermore, the rotating drive head and clamping mechanism allow for adjustment of the tube's rotation during compression, facilitating comprehensive compression of the rotating tube. This design makes the aluminum tube easy to assemble and disassemble, enhancing usability.

[0016] (2) The first sliding pressure head and the clamping plate are driven by setting the first sliding pressure head. Since the clamping plate needs to be located inside the first plug to press against the inner wall of the aluminum tube, the pressure rod can complete the adjustment and driving process of the clamping plate from the first retaining ring head. By setting the control rod including the vertical rod and the grip rod, it is easy to control the rotation of the control rod. After the aluminum tube is extruded and removed, the control rod is adjusted to rotate and move to the reset. The clamping plate and the first sliding pressure head can both move to the reset under the action of the second spring, which is convenient for the next feeding and connection process of the aluminum tube and is easy to use.

[0017] (3) By setting a side limiting baffle to block the clamping member from one side, the positioning stability of the clamping member's rotation position is improved through blocking. At the same time, by setting the end of the clamping member to be arc-shaped, the side limiting baffle can not obstruct the rotation of the clamping member. By setting a first limiting cover plate to abut against the driving member from the periphery, the movement stability of the driving member is improved. By setting a second limiting cover plate to abut against the connecting seat from the periphery, the movement stability of the connecting seat is improved, and the use is convenient.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figures 1-10As shown, the continuous extrusion forming apparatus for aluminum tubes of the present invention includes a base 11, a connecting seat 12, a support 13, a clamping member 21, a clamping joint 22, a driving member 31, a driving head 32, a clamping plate 41, a bracket 42, an end baffle 43, a connecting rod 44, a mounting ring 45, a first spring 46, and an extrusion mechanism 5. The connecting seat 12 is slidably mounted on the base 11 and slides towards or away from the base 11. The support 13 is an arc-shaped support mounted on the base 11 to support the aluminum tube 10. The clamping member 21 is rotatably mounted. On one side of the top of the connecting seat 12, the clamp 22 is rotatably mounted on the clamping member 21. The clamp 22 includes a first retaining ring head 221 and a first plug 222. The first plug 222 is used to insert one end of the aluminum tube 10, and the first retaining ring head 221 is used to abut against the end of the aluminum tube 10. The driving member 31 is slidably mounted on the top side of the connecting seat 12 away from the clamping member 21, and slides towards or away from the clamping member 21. The driving head 32 is rotatably mounted on the driving member 31, and the driving head 32 includes a second retaining ring head 321 and a second plug 222. The first connector 322 and the second plug 322 are used to insert one end of the aluminum tube 10, and the second retaining ring head 321 is used to abut against the end of the aluminum tube 10; the clamping plate 41 is slidably disposed inside the first plug 222, and is used to slide to extend out of the clamping plate 41 and abut against the inner wall of the aluminum tube 10; two brackets 42 are disposed on one side of the clamping member 21 and are respectively located on opposite sides of the bracket 13, for supporting the aluminum tube 10, and the brackets 42 are provided with arc-shaped grooves 421 for fitting against the tube body of the aluminum tube 10, and the brackets 42 are far away from the clamping member 21. One end of component 21 is provided with a rectangular assembly groove 422; an end baffle 43 is rotatably disposed inside the rectangular assembly groove 422 and extends out of the rectangular assembly groove 422 to cover the end of the aluminum tube 10 and to rotate to be located inside the rectangular assembly groove 422; an adapter rod 44 is fixedly connected to the end baffle 43 and extends out to a bracket 42, a mounting ring 45, and a first spring 46 is sleeved on the outside of the adapter rod 44 and fixedly connected to the mounting ring 45 and the bracket 42; an extrusion mechanism 5 is disposed on the base 11 and is used to extrude the aluminum tube 10.

[0023] In specific implementation, the first connector 222 is provided with an assembly through hole 223, and the clamping plate 41 passes through the assembly through hole 223.

[0024] In specific implementation, the end baffle 43 is a small-sized baffle, the width of which is less than the thickness of the aluminum tube 10. It is used to ensure that the end baffle 43 does not obstruct the second retaining ring head 321 from contacting the aluminum tube 10. At the same time, by setting the length of the end baffle 43 to be relatively short, the gap between the end baffle 43 and the aluminum tube 10 is small when the end baffle 43 rotates to the reset position. In this way, when the clamping member 21 is rotated for feeding, even if the aluminum tube 10 accidentally slides, it cannot press the end baffle 43 to rotate significantly, thereby preventing the aluminum tube 10 from accidentally falling out of the end of the bracket 42 due to inertial sliding during feeding.

[0025] In specific implementation, the connecting seat 12 is adjusted to slide upward, making the connecting seat 12 higher than its extrusion position, and the clamping member 21 is adjusted to rotate 180 degrees, so that the clamping member 22 faces the outside of the device of this application; the aluminum tube 10 is placed on the bracket 42 by extruding the end baffle 43 and inserted into the first plug 222. At this time, the aluminum tube 10 is disengaged from the end baffle 43, and the end baffle 43 rotates to the reset under the action of the first spring 46; the clamping member 21 is adjusted to rotate 180 degrees to the reset, at which time the aluminum tube 10 is aligned with the extrusion mechanism 5 and the support 13 in the height direction; the driving member 31 is adjusted to slide towards the clamping member 21, and the driving head 32 is inserted into the end of the aluminum tube 10 to complete the pressing connection of the aluminum tube 10; the connecting seat 12 is adjusted to slide downward to the extrusion position, and the driving head 32 is adjusted to rotate, and the extrusion mechanism 5 completes the extrusion of the aluminum tube 10.

[0026] The continuous extrusion forming apparatus for aluminum tubes in this application uses a clamping joint 22 to insert aluminum tubes 10 for initial connection. The clamping joint 21 is rotatable, allowing the clamping joint 22 to rotate outwards when feeding the aluminum tubes 10 to be extruded, facilitating the insertion connection. A clamping plate 41 is slidably mounted on the inner side of the first insertion joint 222. After inserting the aluminum tube 10 into the first insertion joint 222, the clamping plate 41 can be adjusted outwards and abut against the inner wall of the aluminum tube 10, improving the insertion stability through friction. A bracket 42 supports the aluminum tube 10 from below, further enhancing connection stability. An end baffle 43 is rotatable and located inside a rectangular assembly groove 422, ensuring that the end baffle 43 does not obstruct the aluminum tube. The proper insertion of tube 10 facilitates the connection of the aluminum tube 10. With the first spring 46, after the aluminum tube 10 is fully inserted, the end baffle 43 can rotate to its reset position, blocking the aluminum tube 10 from the end. This prevents the aluminum tube 10 from accidentally falling from the end of the bracket 42 while the clamping member 21 is rotating to its reset position. The drive member 31 is slidably positioned, allowing the drive head 32 to slide to insert the aluminum tube 10 after the clamping member 21 has finished feeding the aluminum tube 10. Through compression, the connection of the aluminum tube 10 is completed. Furthermore, by setting both the drive head 32 and the clamping member 22 to rotate, the drive head 32 can be adjusted to rotate the aluminum tube 10 during compression by the compression mechanism 5. This facilitates the compression mechanism 5 to compress the rotating aluminum tube 10 from all directions, making the assembly and disassembly of the aluminum tube 10 easier and more convenient to use.

[0027] In a preferred embodiment, the end of the second connector 322 is a frustoconical end.

[0028] This design facilitates the adjustment of the second connector 322 to slide into the aluminum tube 10.

[0029] In a preferred embodiment, the system further includes a connecting rod 61, a central reinforcing plate 62, and a second telescopic cylinder 63. A perforated hole 121 is provided at the center of the connecting seat 12, through which the connecting rod 61 passes and is fixedly connected to the support 13 and the base 11. The central reinforcing plate 62 is located inside the perforated hole 121 and is fixedly connected to the central two side walls of the connecting seat 12. The second telescopic cylinder 63 is mounted on the base 11, and its telescopic end is fixedly connected to the central reinforcing plate 62.

[0030] This design, by setting a hollow hole 121, facilitates the connection of the connecting rod 61 to the support 13 through the connecting seat 12. By setting a central reinforcing plate 62 at the center of the hollow hole 121, the structural strength of the connecting seat 12 is improved. By setting a second telescopic cylinder 63 connected to the central reinforcing plate 62, the connecting seat 12 is moved, thereby improving the stability of the second telescopic cylinder 63 driving the connecting seat 12 to move.

[0031] In a preferred embodiment, the device further includes a second spring 71, a first sliding pressure head 72, a pressure rod 73, and a second sliding pressure head 74. The clamping plate 41 has a side mounting plate wall 411 on its side wall. The two ends of the second spring 71 are fixedly connected to the side mounting plate wall 411 and the inner cavity wall of the first connector 222, respectively. The end wall of the clamping plate 41 located inside the first connector 222 is an inclined wall. The first sliding pressure head 72 is slidably disposed inside the first connector 222 and is used to slide to abut against the end wall of the clamping plate 41. The end wall of the first sliding pressure head 72 away from the clamping plate 41 is an inclined wall. The pressure rod 73 slides through the first retaining ring head 221, and the second sliding pressure head 74 is disposed at the end of the pressure rod 73 and is used to move to abut against the end of the first sliding pressure head 72 away from the clamping plate 41.

[0032] It also includes a mounting base 81, a pressure connecting plate 82, and a control lever 83. The mounting base 81 is disposed on the first retaining ring head 221, and the pressure connecting plate 82 is slidably disposed on the mounting base 81. The pressure rod 73 is fixedly connected to the mounting base 81. The control lever 83 is threadedly connected to the mounting base 81 and rotatably connected to the pressure connecting plate 82.

[0033] The control lever 83 is an L-shaped lever, and the mounting base 81 is an L-shaped plate. The control lever 83 includes a vertical rod 831 and a grip rod 832. The vertical rod 831 is threadedly connected to the top wall of the mounting base 81 and is rotatably connected to the pressure connecting plate 82.

[0034] In practice, after the aluminum tube 10 is inserted into the clamping connector 22, the control lever 83 is rotated by the gripping lever 832. The vertical rod 831 pushes the pressing connecting plate 82 to slide downward under the action of the thread. The pressing connecting plate 82 drives the pressing rod 73 and the second sliding pressing head 74 to move downward. The second sliding pressing head 74 abuts against the inclined end wall of the first sliding pressing head 72, pushing the first sliding pressing head 72 to move. The first sliding pressing head 72 abuts against the inclined end wall of the clamping plate 41, pushing the clamping plate 41 to move outward and squeezing the inner side of the aluminum tube 10, thus completing the pressing treatment of the inner wall of the aluminum tube 10.

[0035] This application uses a first sliding pressing head 72 to drive the first sliding pressing head 72 and the clamping plate 41. Since the clamping plate 41 needs to be located inside the first plug 222 to press against the inner wall of the aluminum tube 10, the pressing rod 73 can complete the adjustment and driving process of the clamping plate 41 from the first retaining ring head 221. By setting the control rod 83, including the vertical rod 831 and the grip rod 832, it is easy to control the rotation of the control rod 83. After the aluminum tube 10 is pressed and removed, the control rod 83 is adjusted to rotate and move to the reset position. The clamping plate 41 and the first sliding pressing head 72 can both move to the reset position under the action of the second spring 71, which is convenient for the next feeding and connection process of the aluminum tube 10 and is easy to use.

[0036] In a preferred embodiment, the device further includes a side limiting baffle 122 and a first limiting cover 123. A second limiting cover 111 is disposed on the base 11. The second limiting cover 111 is located outside the connecting seat 12 and abuts against the peripheral wall of the connecting seat 12. The end of the clamping member 21 is an arc-shaped end. The side limiting baffle 122 is disposed on the connecting seat 12 and located on one side of the clamping member 21, and is used to abut against one side wall of the clamping member 21. The first limiting cover 123 is disposed on the connecting seat 12 and located outside the driving member 31, and is used to abut against the peripheral wall of the driving member 31.

[0037] By providing a side limiting baffle 122 to block the clamping member 21 from one side, the positioning stability of the clamping member 21's rotational position is improved through this blocking. Simultaneously, by designing the end of the clamping member 21 as an arc-shaped end, the side limiting baffle 122 does not obstruct the rotation of the clamping member 21. A first limiting cover 123 abuts against the driving member 31 from its circumference to improve the moving stability of the driving member 31. A second limiting cover 111 abuts against the connecting seat 12 from its circumference to improve the moving stability of the connecting seat 12 and facilitate its use.

[0038] In a preferred embodiment, the extrusion mechanism 5 includes a sliding seat 51, a first telescopic cylinder 52, and an extrusion plate 53. A side extension plate seat 112 is provided on one side of the base 11, and a slide rail 113 is provided on the side extension plate seat 112. The sliding seat 51 is slidably disposed on the slide rail 113, and the first telescopic cylinder 52 is disposed on the sliding seat 51. The telescopic end of the first telescopic cylinder 52 extends or retracts in a direction closer to or further away from the aluminum tube 10. The extrusion plate 53 is disposed on the telescopic end of the first telescopic cylinder 52 and is used to extrude the aluminum tube 10.

[0039] The inner side of the first limiting cover plate 123 is provided with a third telescopic cylinder 91, and the telescopic end of the third telescopic cylinder 91 is fixedly connected to the driving component 31. The driving component 31 is provided with a motor 92, which is used to drive the driving head 32 to rotate.

[0040] In practice, the sliding joint 51 is adjusted to slide along the slide rail 113, and the extrusion plate 53 is adjusted to move up and down by the first telescopic cylinder 52 to complete the extrusion forming process of the aluminum tube 10. The drive component 31 is driven to move by the third telescopic cylinder 91, and the drive head 32 is driven by the motor 92 to complete the rotation adjustment process of the aluminum tube 10 during the extrusion forming process.

[0041] This invention also proposes a method for continuous extrusion molding of aluminum tube bodies, which is completed using the aforementioned continuous extrusion molding apparatus for aluminum tube bodies, and includes the following steps: Step 1: Adjust the connecting seat 12 to slide upward so that the connecting seat 12 is higher than its extrusion position, and adjust the clamping part 21 to rotate 180 degrees so that the clamping part 22 faces the outside of the device of this application. Step 2: The aluminum tube 10 is placed on the bracket 42 by pressing the end baffle 43 and is inserted into the first connector 222. At this time, the aluminum tube 10 is disengaged from the end baffle 43, and the end baffle 43 rotates to its reset position under the action of the first spring 46. Step 3: Adjust the clamping piece 21 to rotate 180 degrees to reset. At this time, the aluminum tube 10 is aligned with the extrusion mechanism 5 and the support 13 in the height direction. Step 4: Adjust the drive component 31 to slide closer to the clamping component 21, and insert the drive head 32 into the end of the aluminum tube 10 to complete the clamping connection process of the aluminum tube 10. Step 5: Adjust the connecting seat 12 to slide down to the extrusion station, and adjust the drive head 32 to rotate, so as to complete the extrusion process of the aluminum tube 10 through the extrusion mechanism 5.
