Description

Technical Field

[0001] This invention relates to the technical field of aluminum tube forming, and more particularly to an aluminum tube extrusion system. Background Technology

[0002] An aluminum tube extrusion system is an aluminum tube forming equipment that extrudes high-temperature aluminum ingots to form aluminum tubes within a cylindrical outer mold and outputs the formed aluminum tubes.

[0003] The shape and thickness of the aluminum tube are determined by the exit end die and the inlet end die on both sides of the cylindrical outer die. In the existing aluminum tube extrusion system, the exit end die is mostly connected to one side of the cylindrical outer die in a detachable manner. Therefore, when forming aluminum tubes of different shapes, or when the exit end die is damaged, it is necessary to replace the exit end die. This process is mostly done manually. The temperature of the used exit end die is often high, which not only makes it inconvenient to replace the exit end die, but also reduces the aluminum tube forming efficiency. Summary of the Invention

[0004] Technical problems to be solved

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides an aluminum tube extrusion system, which solves the technical problem that in the prior art, when forming aluminum tubes of different shapes or when the exit end die is damaged, it is necessary to replace the exit end die. This process is mostly done manually, and the temperature of the used exit end die is often high, which not only makes it inconvenient to replace the exit end die, but also reduces the forming efficiency of aluminum tubes.

[0006] Technical solution

[0007] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0008] In a first aspect, the present invention provides an aluminum tube extrusion system, comprising a cylindrical outer die, a first disc body, and a plurality of outlet end dies. The cylindrical outer die is slidable along its own axis, and has a first opening and a second opening at both axial ends. The first disc body is located on one side of the cylindrical outer die. The outlet end dies are all hollow and symmetrically distributed on the first disc body along the axis of the first disc body. One or more outlet end dies form a group of one or more different models. Each outlet end die has a first mating part, and the first mating part can extend into the cylindrical outer die from the second opening. The first disc body is rotatable so that the position of each outlet end die can match the position of the cylindrical outer die, and so that when the cylindrical outer die slides toward the first disc body, the first mating part can be inserted into the cylindrical outer die from the first opening.

[0009] In this technical solution, multiple outlet end dies are set on the first disc body. The first mating part of the outlet end die can cooperate with the cylindrical outer die to realize aluminum tube forming. When the first disc body rotates, different outlet end dies can be aligned with the cylindrical outer die. One or more outlet end dies form a group, and each group of outlet end dies is set with the same model of outlet end die. When an outlet end die of a certain model is damaged, other intact outlet end dies in the same group can be put into use. When it is necessary to form an aluminum tube of a different shape, one outlet end die of the corresponding group can be put into use. In this way, the outlet end die can be quickly replaced, improving the aluminum tube forming efficiency.

[0010] When the position of an outlet end mold corresponds to the position of the cylindrical outer mold, as the cylindrical outer mold slides toward the first disc, the first mating part can always gradually extend from the first opening into the cylindrical outer mold, making the first mating part the outlet side end mold of the aluminum tube.

[0011] In one technical solution of the present invention, the outlet end mold further includes an extension seat, the two ends of which are respectively connected to the first disc body and the first mating part, so as to form a clearance space between the first mating part and the first disc body to satisfy the sliding of the cylindrical outer mold.

[0012] In this technical solution, by setting an extension seat to form a clearance space, it can be ensured that the cylindrical outer mold has sufficient stroke to slide towards the first disc, thereby ensuring that the aluminum tube can be fully extruded and formed.

[0013] In one technical solution of the present invention, the aluminum tube extrusion system further includes an inlet module and an extrusion device, wherein the axis of the inlet module coincides with the axis of the cylindrical outer mold and the inlet module is capable of axial sliding.

[0014] The inlet module includes an inlet end mold and an outlet rod;

[0015] The inlet end mold includes a limiting part and a second mating part that are connected to each other. The second mating part can be inserted into the cylindrical outer mold through the second opening. The second mating part can abut against the cylindrical outer mold. The limiting part can abut against the end face of the second opening. In order to limit the extension length of the second mating part into the cylindrical outer mold, a force is applied to the cylindrical outer mold along the axis of the cylindrical outer mold and in the direction of the outlet end mold.

[0016] The inlet end mold is sleeved on and supported on the outlet rod, and is axially slidably connected to the outlet rod;

[0017] The extrusion device can independently apply a force to the outlet rod and the inlet die in the direction of the outlet die along the axis of the cylindrical outer die.

[0018] In this technical solution, the aluminum tube extrusion system also includes an inlet module and an extrusion device. The inlet module can close the second opening of the cylindrical outer mold. The extrusion device extrudes the inlet module, which in turn extrudes the aluminum ingot and the cylindrical outer mold. With the help of the outlet end mold, the aluminum tube can be formed.

[0019] The inlet module includes an inlet end die and an outlet rod. The outlet rod can form a central through hole in the aluminum tube under the extrusion of the extrusion device. The inlet end die can extrude the aluminum ingot and push the aluminum ingot with the central through hole formed towards the outlet end die, thus completing the forming of the aluminum tube.

[0020] The inlet end mold is fitted and supported on the outlet rod, eliminating the need for additional components to support the inlet end mold and simplifying the structure of the inlet module.

[0021] In one technical solution of the present invention, the aluminum tube extrusion system further includes a second disc, a plurality of inlet modules are symmetrically distributed on the second disc along the central axis of the second disc, an outlet rod passes through and is slidably connected to the second disc, and an inlet end die is disposed on the side of the second disc close to the cylindrical outer die;

[0022] The second disc is rotatable so that each inlet module can engage with the cylindrical outer mold; the second disc is also slidable along the axis of the cylindrical outer mold.

[0023] In this technical solution, multiple inlet modules are arranged in a centrally symmetrical manner on the second disc. When the second disc rotates, the corresponding inlet modules can be aligned with the cylindrical outer mold, thereby improving the flexibility of the inlet modules.

[0024] One or more inlet modules are grouped together, and each group of inlet modules is set to the same model. When an inlet module of a certain model is damaged, other intact inlet modules in the same group can be put into use. When it is necessary to form an aluminum tube of a different shape, one inlet module of the corresponding group can be put into use. In this way, the inlet modules can be quickly replaced, and the aluminum tube forming efficiency can be improved.

[0025] The second disc is designed to be slidable so that the inlet module can move closer to or further away from the cylindrical outer mold without the aid of an extrusion device. When aluminum ingots are fed into the cylindrical outer mold, the sliding of the second disc can ensure that there is enough space between the inlet module and the cylindrical outer mold to allow the aluminum ingots to enter the cylindrical outer mold.

[0026] In one technical solution of the present invention, the aluminum tube extrusion system further includes a first rotary drive, a second rotary drive, and a telescopic drive. The torque output end of the first rotary drive is connected to the first disc body; the main body of the second rotary drive is connected to the power output end of the telescopic drive, and the second disc body is connected to the power output end of the second rotary drive.

[0027] In this technical solution, both the first rotation drive and the second rotation drive can be configured as drive components including servo motors. By controlling the rotation angle of the servo motors, the first or second disc can be rotated by the required angle, so that the required outlet end mold and inlet module correspond to the cylindrical outer mold.

[0028] The second disc can also be axially slid by a telescopic drive component, which can be configured as a hydraulic telescopic rod. This allows the second disc to move away from or closer to the second opening of the cylindrical outer mold, thus making room for the second opening and facilitating the entry of aluminum ingots into the inner cavity of the cylindrical outer mold. Alternatively, the second opening can be closed by the inlet end mold on the second disc.

[0029] In one technical solution of the present invention, the extrusion device includes a first extrusion rod and a second extrusion rod. The second disc has a through hole symmetrically arranged along the axis of the outlet rod. The first extrusion rod can pass through the through hole to extrude the inlet end mold. The end of the outlet rod away from the cylindrical outer mold has a mating groove. The second extrusion rod can match the mating groove and extrude the bottom of the mating groove.

[0030] In this technical solution, the extrusion device is normally separated from the inlet end mold and the second disc, so the extrusion device will not interfere with the rotation of the second disc.

[0031] After the inlet module aligns with the cylindrical outer mold, the first extrusion rod can always pass through the through hole and act on the inlet end mold, allowing the inlet end mold to slide towards the cylindrical outer mold and extrude the aluminum ingot; the second extrusion rod applies extrusion force to the outlet rod through the mating groove of the extrusion outlet rod, and this extrusion force can form the central hole of the aluminum ingot.

[0032] In one technical solution of the present invention, the second extrusion rod and the mating groove, as well as the inlet end mold and the outlet rod, are magnetically attracted to each other, and the magnetic attraction force between the second extrusion rod and the mating groove is less than the magnetic attraction force between the inlet end mold and the outlet rod.

[0033] In this technical solution, after the aluminum tube is formed, the outlet rod and the inlet end die need to be withdrawn from their state of engagement with the cylindrical outer die. Since the second extrusion rod and the mating groove, as well as the inlet end die and the outlet rod, are magnetically attracted to each other, the outlet rod can be withdrawn synchronously during the withdrawal of the second extrusion rod, provided that the first extrusion rod has withdrawn. When the outlet rod withdraws to the state where the inlet end die abuts against the second disc, the magnetic attraction between the second extrusion rod and the mating groove is less than the magnetic attraction between the inlet end die and the outlet rod. Therefore, the outlet rod and the second extrusion rod will separate from each other, and the inlet end die will remain on the outlet rod. This further improves the ease of use of the aluminum tube extrusion system.

[0034] In one embodiment of the present invention, the extension seat has an outlet hole that matches the position of the first mating part.

[0035] In this technical solution, the formed aluminum tube can be output from the tube hole, which facilitates the aluminum tube cutting work.

[0036] In one technical solution of the present invention, the aluminum tube extrusion system further includes a connecting plate, and the cylindrical outer die is slidably connected to the connecting plate; the aluminum tube extrusion system further includes a first reset component, which is capable of maintaining the application of a sliding force to the cylindrical outer die in the direction away from the exit end die.

[0037] In this technical solution, the connecting plate is used to support the cylindrical outer mold. After the cylindrical outer mold slides towards the outlet end mold, the first reset member provides a reset force for the cylindrical outer mold to ensure that the cylindrical outer mold and the outlet end mold remain detached when the aluminum tube forming operation is not performed, thereby ensuring the reliability of the aluminum tube extrusion system.

[0038] In one technical solution of the present invention, the first reset component includes a first magnetic absorbing element and a second magnetic absorbing element respectively disposed on the cylindrical outer mold and the connecting plate, and the first magnetic absorbing element and the second magnetic absorbing element are located on the side of the connecting plate close to the second disk body, and the first magnetic absorbing element and the second magnetic absorbing element are magnetically repulsive.

[0039] In this technical solution, the first reset component is configured as a magnetic reset. Since the cylindrical outer mold is close to the exit mold, if it is reset by adsorption force, the first and second magnetic components need to be set on the side of the second plate near the exit mold. Since there is a certain distance between the first and second magnetic components, it may be difficult to achieve reliable reset and reset by repulsion. Since the end of the cylindrical outer mold away from the exit mold will always slide to a position very close to the second plate after the aluminum tube is formed, setting the first and second magnetic components on the side of the connecting plate close to the second plate and resetting by magnetic force can ensure that a large reset force can be formed between the first and second magnetic components, thereby improving the reset reliability of the cylindrical outer mold.

[0040] Beneficial effects

[0041] The beneficial effects of this invention are as follows: multiple outlet end molds are all set on the first disc body, and the first mating part of the outlet end mold can cooperate with the cylindrical outer mold to realize aluminum tube forming. When the first disc body rotates, different outlet end molds can be aligned with the cylindrical outer mold. One or more outlet end molds are grouped together, and each group of outlet end molds is set with the same model of outlet end mold. When an outlet end mold of a certain model is damaged, other intact outlet end molds in the same group can be put into use. When it is necessary to form another aluminum tube of a different shape, one outlet end mold of the corresponding group can be put into use. In this way, the outlet end mold can be quickly replaced, and the aluminum tube forming efficiency can be improved. Attached Figure Description

[0057] To better explain and facilitate understanding of this invention, the following description is provided in conjunction with the appendix. Figure 1-7 The present invention will be described in detail through specific embodiments. In this document, directional terms such as "upper" and "lower" are used interchangeably with other directional terms. Figure 1 The orientation is used as a reference.

[0058] Example 1:

[0059] Reference Figures 1-7 This invention provides an aluminum tube extrusion system, including a cylindrical outer die 1, a first disc 2, and multiple outlet end dies 3. The cylindrical outer die 1 is slidable along its own axis, and has a first opening 100 and a second opening 200 at both axial ends. The first disc 2 is located on one side of the cylindrical outer die 1. The outlet end dies 3 are all hollow and symmetrically distributed on the first disc 2 along its central axis. One or more outlet end dies 3 form a group of one or more different models, and each outlet end die 3 includes a first mating part 31. The first disc 2 is rotatable so that the position of each outlet end die 3 can match the position of the cylindrical outer die 1, that is, the axis of each outlet end die 3 can coincide with the axis of the cylindrical outer die 1. Thus, when the cylindrical outer die 1 slides towards the first disc 2, the first mating part 31 can be inserted into the cylindrical outer die 1 through the first opening 100.

[0060] In this embodiment, multiple outlet end molds 3 are all disposed on the first disc body 2, and the first mating part 31 of the outlet end mold 3 can mate with the cylindrical outer mold 1 to realize aluminum tube forming.

[0061] When the first disc 2 rotates, different exit end dies 3 can be aligned with the cylindrical outer die 1. One or more exit end dies 3 form a group, and each group of exit end dies 3 is set with the same model. When an exit end die 3 of a certain model is damaged, other intact exit end dies 3 in the same group can be used. When it is necessary to form an aluminum tube of a different shape, one of the exit end dies 3 in the corresponding group can be used. In this way, the exit end dies 3 can be quickly replaced, improving the aluminum tube forming efficiency.

[0062] When the position of an outlet end mold 3 corresponds to the position of the cylindrical outer mold 1, as the cylindrical outer mold 1 slides toward the first disc body 2, the first mating part 31 can always be gradually inserted into the cylindrical outer mold 1 from the first opening 100, so that the first mating part 31 becomes the outlet side end mold of the aluminum tube.

[0063] Specifically, the cylindrical outer mold 1 can be set as a metal cylinder, and the cylindrical outer mold 1 needs to be separated from the outlet end mold 3 when the first disc 2 rotates.

[0064] The first disc 2 can be set as a metal disc. The through hole in the middle part of the first mating part 31 of the outlet end mold 3 is a forming hole. The shape and size of the forming hole determine the shape and size of the final formed aluminum tube. Forming holes of different sizes and shapes can form aluminum tubes of different shapes and outer diameters.

[0065] In this embodiment, the outlet mold 3 further includes an extension seat 32, the two ends of which are respectively connected to the first disc body 2 and the first mating part 31, and are welded together to form a clearance space between the first mating part 31 and the first disc body 2 to allow the cylindrical outer mold 1 to slide. The extension seat 32 is also a hollow structure and is coaxially arranged with the first mating part 31.

[0066] In this embodiment, by setting the extension seat 32 to form a clearance space, it can be ensured that the cylindrical outer mold 1 has sufficient stroke to slide in the direction of the first disc 2, thereby ensuring that the aluminum tube can be fully extruded and formed.

[0067] Specifically, the extension seat 32 can be connected to the first disc body 2 and the first mating part 31 by welding. The projection contour of the extension seat 32 towards the first mating part 31 along the axis of the outlet mold 3 should fall within the projection contour of the first mating part 31 in the same direction, or coincide with the projection contour of the first mating part 31 in the same direction, so as to ensure that the extension seat 32 can also be inserted into the inner cavity of the cylindrical outer mold 1.

[0068] In this embodiment, the extension seat 32 has a tube outlet 400 that matches the position of the first mating part 31. The formed aluminum tube can be output from the tube outlet 400, which facilitates the aluminum tube cutting process.

[0069] In this embodiment, the aluminum tube extrusion system further includes an inlet module 4 and an extrusion device 5. The axis of the inlet module 4 coincides with the axis of the cylindrical outer mold 1, and the inlet module 4 can slide axially.

[0070] Inlet module 4 includes inlet end mold 41 and outlet rod 42;

[0071] The inlet end mold 41 includes a limiting part 411 and a second mating part 412 connected to each other. The second mating part 412 can be inserted into the cylindrical outer mold 1 through the second opening 200. The second mating part 412 can abut against the cylindrical outer mold 1. The limiting part 411 can abut against the end face of the second opening 200. In order to limit the extension length of the second mating part 412 into the cylindrical outer mold 1, while applying a force to the cylindrical outer mold 1 in the direction of the axis of the cylindrical outer mold 1 pointing towards the outlet end mold 3.

[0072] The inlet end mold 41 is sleeved on and supported on the outlet rod 42, and is axially slidably connected to the outlet rod 42;

[0073] The extrusion device 5 can independently apply a force to the outlet rod 42 and the inlet end die 41 in the direction from the axis of the cylindrical outer die 1 to the outlet end die 3.

[0074] In this embodiment, the inlet module 4 can close the second opening 200 of the cylindrical outer mold 1, the extrusion device 5 extrudes the inlet module 4, the inlet module 4 extrudes the aluminum ingot and the cylindrical outer mold 1, and with the help of the outlet end mold 3, the aluminum tube can be formed.

[0075] The inlet module 4 includes an inlet end mold 41 and an outlet rod 42. The outlet rod 42 can form a central through hole in the aluminum tube under the extrusion of the extrusion device 5. The inlet end mold 41 can extrude the aluminum ingot and extrude the aluminum ingot with the central through hole to the outlet end mold 3, thus completing the forming of the aluminum tube.

[0076] The inlet end mold 41 is fitted and supported on the outlet rod 42, and no additional components are needed to support the inlet end mold 41, which simplifies the structure of the inlet module 4.

[0077] Specifically, the limiting part 411 can be configured as a limiting flange, and the second mating part 412 is in clearance fit with the inner cavity of the cylindrical outer mold 1.

[0078] In this embodiment, the aluminum tube extrusion system further includes a second disc 6, on which multiple inlet modules 4 are symmetrically distributed along the central axis of the second disc 6. An outlet rod 42 passes through and is slidably connected to the second disc 6. If a through hole is provided on the second disc 6 at a position corresponding to the inlet module 4, the outlet rod 42 passes through and is slidably connected within the through hole. The inlet end mold 41 is located on the side of the second disc 6 near the cylindrical outer mold 1. The second disc 6 is rotatable so that each inlet module 4 can engage with the cylindrical outer mold 1; the second disc 6 is also slidable along the axial direction of the cylindrical outer mold 1.

[0079] In this embodiment, multiple inlet modules 4 are arranged in a centrally symmetrical manner on the second disk 6. When the second disk 6 rotates, the corresponding inlet module 4 can be aligned with the cylindrical outer mold 1, thereby improving the flexibility of the inlet module 4 in use.

[0080] One or more inlet modules 4 are grouped together. Each group of inlet modules 4 is set to the same model of inlet module 4. When an inlet module 4 of a certain model is damaged, other intact inlet modules 4 in the same group can be put into use. When it is necessary to form an aluminum tube of a different shape, one inlet module 4 of the corresponding group can be put into use. In this way, the inlet module 4 can be quickly replaced, improving the aluminum tube forming efficiency.

[0081] The second disc 6 is made to be slidable so that the inlet module 4 can approach or move away from the cylindrical outer mold 1 without the aid of the extrusion device 5. When aluminum ingots are input into the cylindrical outer mold 1, by controlling the sliding of the second disc 6, sufficient space can be ensured between the inlet module 4 and the cylindrical outer mold 1 to allow the aluminum ingots to enter the cylindrical outer mold 1.

[0082] Specifically, the second disc 6 can be configured as a metal disc, and the end of the outlet rod 42 near the aluminum ingot is the extrusion end, which extrudes the aluminum ingot to form a central hole.

[0083] In this embodiment, the aluminum tube extrusion system further includes a first rotary drive, a second rotary drive, and a telescopic drive. The torque output end of the first rotary drive is connected to the first disc 2. The main body of the second rotary drive is connected to the power output end of the telescopic drive, and the second disc 6 is connected to the power output end of the second rotary drive to meet the requirement that the second disc 6 can both rotate and slide axially.

[0084] In this embodiment, both the first rotation drive and the second rotation drive can be configured as drive components including servo motors. By controlling the rotation angle of the servo motor, the first disk 2 or the second disk 6 can be rotated by the required angle, so that the required outlet end mold 3 and inlet module 4 correspond to the cylindrical outer mold 1.

[0085] The second disc 6 can also be axially slid by a telescopic drive component. The telescopic drive component can be configured as a hydraulic telescopic rod, so that the second disc 6 can be moved away from or closer to the second opening 200 of the cylindrical outer mold 1, so as to make room for the position of the second opening 200, thereby facilitating the entry of aluminum ingots into the inner cavity of the cylindrical outer mold 1, or the second opening 200 can be closed by the inlet end mold 41 on the second disc 6.

[0086] In this embodiment, the extrusion device 5 includes a first extrusion rod 51 and a second extrusion rod 52. The second disc 6 has a through hole 500 symmetrically arranged along the axis of the outlet rod 42. The first extrusion rod 51 can pass through the through hole 500 to extrude the inlet end mold 41. The end of the outlet rod 42 away from the cylindrical outer mold 1 has a mating groove 300. The second extrusion rod 52 can match the mating groove 300 and extrude the bottom of the groove 300.

[0087] Specifically, in order to ensure the stability of the inlet end mold 41 when the first extrusion rod 51 extrudes the inlet end mold 41, multiple through holes 500 can be provided, and the multiple through holes 500 are symmetrically arranged along the axis of the outlet rod 42, such as two first extrusion rods 51.

[0088] In this embodiment, the extrusion device 5 is normally separated from the inlet end mold 41 and the second disc 6. Therefore, the extrusion device 5 will not interfere with the rotation of the second disc 6.

[0089] After the inlet module 4 aligns with the cylindrical outer mold 1, the first extrusion rod 51 can always pass through the through hole 500 and act on the inlet end mold 41, allowing the inlet end mold 41 to slide towards the cylindrical outer mold 1 and extrude the aluminum ingot. The second extrusion rod 52 applies extrusion force to the outlet rod 42 through the mating groove 300 of the extrusion outlet rod 42, which can form the central hole of the aluminum ingot.

[0090] Specifically, the first extrusion rod 51 and the second extrusion rod 52 can both be configured as the actuating end of the telescopic member, which can be configured as a hydraulic telescopic rod.

[0091] The specific operation during aluminum tube extrusion is as follows:

[0092] S1: The telescopic drive component drives the main body of the second rotary drive component to slide, thereby causing the second disc 6 to slide away from the cylindrical outer mold 1, freeing up assembly space for the aluminum ingot, and then placing the aluminum ingot into the inner cavity of the cylindrical outer mold 1, corresponding to... Figure 1 The first state shown;

[0093] S2: The first and second rotational drive components control the rotation of the corresponding first disc 2 and / or second disc 6, thereby ensuring that the models of the outlet module 3 and the inlet module 4 meet the requirements. Figure 1 The first state shown;

[0094] S3: The telescopic drive component drives the second disc 6 to slide towards the cylindrical outer mold 1 until the stroke of the extrusion device 5 and the inlet module 4 towards the cylindrical outer mold 1 meets the stroke requirements for extruding the aluminum ingot. The extrusion device 5 extrudes the inlet end mold 41 and the outlet rod 42 until one end of the aluminum ingot abuts against the outlet end mold 3, and the other end abuts against the inlet end mold 41 and the outlet rod 42, while the aluminum ingot remains within the inner cavity of the cylindrical outer mold 1. Figure 2 The second state shown and Figure 3 The third state shown, Figure 2 Only the 42-hole rod is used to extrude aluminum ingots. Figure 3 The central outlet rod 42 and the inlet end die 41 jointly extrude aluminum ingots;

[0095] S4: The second extrusion rod 52 in the extrusion device 5 continuously extrudes the hole rod 42 until the aluminum ingot is extruded with a blind hole of a predetermined length, corresponding to... Figure 4 The fourth state shown;

[0096] S5: The inlet die 41 is continuously extruded by the first extrusion rod 51 in the extrusion device 5, corresponding to... Figure 5 The fifth state is shown, in which the aluminum tube is extruded.

[0097] S6: Perform demolding.

[0098] Example 2:

[0099] Reference Figure 3 In addition to possessing all the technical solutions of the above embodiments, the embodiments of the present invention further possess the following technical solutions:

[0100] The second extrusion rod 52 and the mating groove 300, as well as the inlet end mold 41 and the outlet rod 42, are magnetically attracted to each other, and the magnetic attraction between the second extrusion rod 52 and the mating groove 300 is less than the magnetic attraction between the inlet end mold 41 and the outlet rod 42.

[0101] In this embodiment, after the aluminum tube is formed, the outlet rod 42 and the inlet end mold 41 need to be withdrawn from their state of engagement with the cylindrical outer mold 1. Since the second extrusion rod 52 and the mating groove 300, as well as the inlet end mold 41 and the outlet rod 42, are magnetically attracted to each other, the outlet rod 42 can be withdrawn synchronously during the withdrawal of the second extrusion rod 52 from the second disc 6, provided that the first extrusion rod 51 has withdrawn from the second disc 6. When the outlet rod 42 withdraws to the state where the inlet end mold 41 abuts against the second disc 6, the magnetic attraction between the second extrusion rod 52 and the mating groove 300 is less than the magnetic attraction between the inlet end mold 41 and the outlet rod 42. Therefore, the outlet rod 42 and the second extrusion rod 52 will disengage from each other, while the inlet end mold 41 will remain on the outlet rod 42. This further improves the ease of use of the aluminum tube extrusion system.

[0102] Specifically, on the side wall opposite to the second extrusion rod 52 and the mating groove 300, for example, a set of elongated permanent magnets can be embedded in the outer wall of the second extrusion rod 52 and extend along the axial direction of the second extrusion rod 52, and another set of elongated permanent magnets can be embedded in the inner wall of the mating groove 300 and extend along the axial direction of the outlet rod 42, and the two sets of permanent magnets can attract each other.

[0103] Permanent magnets that attract each other are provided on the opposite sidewalls of the inlet end mold 41 and the outlet rod 42. For example, a set of elongated permanent magnets is embedded in the inner wall of the through hole of the inlet end mold 41 through the outlet rod 42 and extends along the axial direction of the outlet rod 42, and another set of elongated permanent magnets is embedded in the outer wall of the outlet rod 42 and extends along the axial direction of the outlet rod 42. The two sets of permanent magnets attract each other.

[0104] Example 3:

[0105] Reference Figure 3 In addition to possessing all the technical solutions of any of the above embodiments, the embodiments of the present invention further possess the following technical solutions:

[0106] The aluminum tube extrusion system also includes a connecting plate 7, on which the cylindrical outer die 1 is slidably connected; the aluminum tube extrusion system also includes a first reset assembly, which is capable of maintaining the application of a sliding force to the cylindrical outer die 1 in the direction away from the exit end die 3.

[0107] In this embodiment, the connecting plate 7 is used to support the cylindrical outer mold 1. After the cylindrical outer mold 1 slides towards the outlet mold 3, the first reset member provides a reset force for the cylindrical outer mold 1 to ensure that the cylindrical outer mold 1 and the outlet mold 3 remain detached when the aluminum tube forming operation is not performed, thereby ensuring the reliability of the aluminum tube extrusion system.

[0108] In this embodiment, the first reset component includes a first magnetic chuck and a second magnetic chuck respectively disposed on the cylindrical outer mold 1 and the connecting plate 7, and the first magnetic chuck and the second magnetic chuck are located on the side of the connecting plate 7 close to the second disk 6, and the first magnetic chuck and the second magnetic chuck are magnetically repulsive.

[0109] Since the cylindrical outer mold 1 will always slide to a position very close to the second disc 6 after the aluminum tube is formed near the exit mold 3, the first magnetic suction component and the second magnetic suction component are set to be located on the side of the connecting plate 7 near the second disc 6. By using magnetic force reset, it can be ensured that a large reset force can be formed between the first magnetic suction component and the second magnetic suction component, thereby improving the reset reliability of the cylindrical outer mold 1.

[0110] Specifically, such as Figure 1 As shown in the orientation, the first magnetic attractor can be placed on the flange at the right end of the outlet mold, and the second magnetic attractor can be placed on the right side wall of the connecting plate 7, so that the magnetic poles of the first magnetic attractor and the second magnetic attractor repel each other.

[0111] It can be understood that, except for conflicting parts, the above embodiments 1-3 can be freely combined to form other embodiments of the present invention.

[0112] In the description of this invention, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0113] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0114] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first and second features are in direct contact, or that they are in indirect contact through an intermediate medium. Furthermore, "above," "over," or "on top" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," or "beneath" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0115] The term "comprising" or any other similar term is intended to cover non-exclusive inclusion, such that a process, article, or apparatus / device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to those processes, articles, or apparatus / devices.

[0116] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
