Description

TECHNICAL FIELD

[0001] The utility model belongs to the semi -solid forming technical field especially relates to an automatic semi -solid forming machine for aluminum flat tube processing. BACKGROUND

[0002] The automatic semi -solid forming machine controls the semi -solid characteristics of aluminum alloy material through highly precise technical means, and ingeniously combines mold design and advanced forming process, realizes the full -automatic process of aluminum flat tube production. Its operation mechanism covers multiple precision links from material preparation to semi -solid processing, forming, shaping and repeated operation.

[0003] In the semi -solid forming technology system of aluminum flat tube, the pouring link plays an important role. At present, this link mainly depends on two modes of mechanical arm and manual operation, but both have their own limitations and shortcomings.

[0004] Under the manual operation mode, the worker needs to use the crucible equipped with the lengthened handle to carefully scoop a certain amount of aluminum water from the heating pool (i.e. semi -solid aluminum water pool), and then accurately pour it into the mold through the pouring gate. However, this process not only makes it difficult to accurately control the amount of aluminum water taken out, but also hides the security risk that cannot be ignored, and puts forward very high requirements for the operation skills and safety consciousness of the workers.

[0005] In contrast, mechanical arm operation significantly improves the automation level and safety of production. However, in actual application, the introduction of mechanical arm also brings a series of new challenges. In order to ensure the smooth operation of the mechanical arm, enough space for the case and arm is needed, which undoubtedly increases the complexity of equipment layout. More troublesome is that in some special environments, due to the limitation of the activity range of the mechanical arm, the stirring shaft cannot be directly installed in the heating pool. This means that the mechanical arm needs to go through an additional stirring step to ensure the uniformity of the aluminum water after taking it out, which undoubtedly increases the complexity and time cost of the production process.

[0006] Therefore, it is necessary to invent an automatic semi -solid forming machine for aluminum flat tube processing. UTILITY MODEL CONTENTS

[0026] As shown in the accompanying Figure 1 to the accompanying Figure 4 drawings:

[0027] The utility model provides a kind of automatic semi-solid forming machine for aluminum flat tube processing, including pouring workbench 1, support frame 2, positioning column 3, forming die 4, extrusion cylinder 5, automatic pouring device 6, support platform 7, heater 8, stirring drive component 9 and stirrer 10, support frame 2 is fixedly installed below pouring workbench 1, two mirror image symmetries the forming die 4 of sliding installation is positioned in column 3 above pouring workbench 1, each the forming die 4 is fixed with the extrusion cylinder 5 output end fixedly installed outside pouring workbench 1;Automatic pouring device 6 is located above two the forming die 4, and fixedly installed on support platform 7, the semi-solid slurry cylinder 67 outside of automatic pouring device 6 is equipped with heater 8, the upper end of stirrer 10 in semi-solid slurry cylinder 67 is fixed with the output end of stirring drive component 9, heater 8 and stirring drive component 9 are fixedly installed on the bracket 68 of automatic pouring device 6.

[0028] Further, automatic pouring device 6 includes work platform 61, sealing sliding frame 62, pouring pipe mouth 63 and pouring cylinder 64, work platform 61 is stably installed on support platform 7, as the operation basis of entire automatic pouring device 6. On the upper surface of work platform 61, sealing sliding frame 62 is designed, for guiding the sliding of pouring crucible 65, while also play certain anti-outflow function. Pouring cylinder 64 is fixedly installed on the outer surface of sealing sliding frame 62, provides power for the movement of pouring crucible 65. In addition, pouring pipe mouth 63 is also carefully arranged on work platform 61, and its position is just located above the pouring gate formed after the combination of two forming dies 4, to ensure that aluminum water can be accurately injected into the mold.

[0029] Further, in addition to the above components, automatic pouring device 6 also includes pouring crucible 65, blocking plate 66, semi-solid slurry cylinder 67 and bracket 68 and other key components. The bottom of pouring crucible 65 is slidably installed in sealing sliding frame 62, and can be moved to the specified position as needed. The upper side of pouring crucible 65 is fixed with blocking plate 66, which is located below semi-solid slurry cylinder 67, and plays a role in controlling the outflow of aluminum water. Semi-solid slurry cylinder 67 is fixedly installed inside bracket 68, for storing semi-solid aluminum water to be poured.

[0030] Further, flow-through openings 69 are provided in the bottom of pouring crucible 65, blocking plate 66 and semi-solid slurry cylinder 67. When the flow-through openings 69 of pouring crucible 65 and blocking plate 66 are on the same vertical line, the semi-solid aluminum water inside semi-solid slurry cylinder 67 can smoothly enter pouring crucible 65 through the flow-through opening 69 of blocking plate 66. When the flow-through openings 69 of the three are not on the same vertical line, blocking plate 66 effectively blocks the flow-through opening 69 at the bottom of semi-solid slurry cylinder 67, preventing aluminum water from accidentally flowing out.

[0031] Further, the pouring crucible 65 is designed very ingeniously, and the inside of the pouring crucible 65 can always store a constant amount of semi-solid aluminum water, and the amount is exactly the same as the amount required for the aluminum flat tube forming. This design not only simplifies the pouring process, but also ensures that the amount of aluminum water poured each time is accurate, thereby improving the quality and consistency of the product.

[0032] Further, the pouring crucible 65 can make linear reciprocating motion in the sealed sliding frame 62, and this feature enables the pouring crucible 65 to move to different positions as needed. When the flow-through opening 69 at the bottom of the pouring crucible 65 is in the same vertical line as the pouring pipe opening 63 of the working platform 61, the semi-solid aluminum water in the pouring crucible 65 can smoothly enter the sprue of the forming mold 4 through the pouring pipe opening 63. This process is completely controlled by machinery and does not require human intervention, greatly improving production efficiency and safety.

[0033] The working principle is as follows: first, the automatic semi-solid forming machine for aluminum flat tube processing provided by the utility model starts to work, and the whole system is in standby state. The pouring workbench 1 is stably supported by the support frame 2 to support the whole forming area, and the two mirror-symmetrical forming molds 4 are slidably installed above the pouring workbench 1 through the positioning column 3 and are connected with the output end of the externally fixed and installed extrusion cylinder 5, so that the aluminum flat tube can be extrusion formed in the subsequent forming process. The pouring workbench 1 and the forming mold 4 are provided with a cooling system, which is used for subsequent cooling and shaping.

[0034] Then, the automatic pouring device 6 begins to play its key role. The automatic pouring device 6 is fixedly installed on the support platform 7, and the semi-solid slurry cylinder 67 in the automatic pouring device 6 stores the semi-solid aluminum water to be poured. In order to maintain the appropriate temperature and uniformity of the aluminum water, the semi-solid slurry cylinder 67 is externally provided with a heater 8, and the stirrer 10 in the semi-solid slurry cylinder 67 continuously rotates under the driving of the stirring driving part 9, so that the aluminum water will not stratify or solidify due to long-term standing.

[0035] Then, when the system receives a pouring instruction, the pouring cylinder 64 starts to work and drives the pouring crucible 65 to make linear reciprocating motion in the sealed sliding frame 62. During the movement, the flow-through opening 69 of the blocking plate 66 fixedly installed on the pouring crucible 65 will gradually align with the flow-through opening 69 at the bottom of the semi-solid slurry cylinder 67, and the pouring cylinder 64 stops working. At this time, the semi-solid aluminum water in the semi-solid slurry cylinder 67 will flow into the pouring crucible 65 through the flow-through opening 69 of the blocking plate 66 under the action of gravity. Since the pouring crucible 65 is designed to always store a constant amount of semi-solid aluminum water, the amount of aluminum water poured each time is accurate, and the amount is exactly the same as the amount required for the aluminum flat tube forming.

[0036] Subsequently, the pouring cylinder 64 is restarted, and the pouring crucible 65 moves in the opposite direction, and when the pouring crucible 65 moves to the top of the pouring pipe 63 of the working platform 61, the flow port 69 at the bottom of the pouring crucible 65 is aligned with the pouring pipe 63. At this time, the semi-solid aluminum liquid in the pouring crucible 65 will flow into the sprue of the forming mold 4 through the pouring pipe 63 under the action of gravity. This process is completely controlled by machinery and does not require manual intervention, which improves production efficiency and ensures the accuracy and safety of the pouring process.

[0037] Finally, when the aluminum liquid is completely injected into the two combined forming molds 4 (pre-combined by the extrusion cylinder 5), the extrusion cylinder 5 works again to continuously push the forming mold 4 to extrude the aluminum liquid, and the cooling system is started. After a period of cooling and solidification, the aluminum flat tube is successfully formed. At this time, the forming mold 4 can be opened, and the formed aluminum flat tube can be taken out and processed. The coordinated work of the automatic pouring device 6 and other key components ensures the efficient, accurate and safe production of the aluminum flat tube.

[0038] The technical scheme disclosed in the utility model, or the technical scheme designed by the person skilled in the art under the inspiration of the technical scheme of the utility model, and the similar technical scheme achieving the above technical effects all fall within the protection scope of the utility model.
