Quick die changing and uniform cooling structure of aluminum profile extrusion die

Abstract

This invention discloses a rapid die-changing and uniform cooling structure for aluminum profile extrusion dies. The structure includes a drive platform with a coordinate drive mechanism and a die platform with a rotating turntable driven by a motor. A sleeve at the end of the drive platform can be coaxially fitted with a roller on the slider under the drive of the coordinate mechanism. The roller extends radially, and its free end always extends beyond the outer edge of the turntable, thereby directly driving the slider and the die on it to reciprocate between the storage position and the use position along the radial direction of the turntable, significantly improving die-changing efficiency and automation. To solve the problem of uneven cooling, the turntable is equipped with layered heat dissipation fins with clearance notches. When the die retracts to the storage position, the heat dissipation fins form a semi-enclosed coverage. This invention achieves flexible and rapid die switching through automatic mechanical connection and achieves uniform heat dissipation from all angles through the combined action of die rotation and heat dissipation fins.

Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment for aluminum profile extrusion processing, and more specifically to a rapid die-changing and uniform cooling structure for aluminum profile extrusion dies. Background Technology

[0002] In the aluminum profile extrusion process, the diverse cross-sectional shapes of the products necessitate frequent die changes. Traditional die-changing methods rely heavily on manual alignment and mechanical bolt fixing, which is time-consuming and impacts the continuous operation efficiency of the production line. Furthermore, the high temperature of the die after extrusion means that allowing it to cool naturally can lead to thermal stress concentration due to uneven heat dissipation rates across different parts of the die. This can cause die deformation, affecting its lifespan and the forming accuracy of subsequent products. Therefore, achieving rapid die switching and uniform heat dissipation is a problem that needs to be solved in this field. Summary of the Invention

[0003] This invention provides a rapid die-changing and uniform cooling structure for aluminum profile extrusion dies to solve the problems of low die-changing efficiency and uneven die cooling in the prior art.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a rapid die-changing and uniform cooling structure for aluminum profile extrusion dies, comprising: A drive platform is provided with a coordinate drive mechanism for moving in a two-dimensional plane in the X and Y directions. The moving end of the coordinate drive mechanism is connected to a drive block, and the drive block is provided with a sleeve. A mold platform has a turntable rotatably mounted on it, which is driven to rotate by a motor; multiple sliders are arranged in a circumferential array on the turntable, which can slide back and forth radially along the turntable, and each slider is provided with a mold base for supporting the mold; Each slider is fixedly provided with an insertion rod, which extends radially outward along the turntable, and the free end of the insertion rod away from the slider always extends beyond the outer edge of the turntable and is set at the same height as the sleeve. The sleeve can be coaxially fitted with any of the insertion rods under the drive of the coordinate driving mechanism; after the sleeve is fitted with the target insertion rod, the coordinate driving mechanism drives the sleeve to move along the radial direction of the turntable, so as to directly drive the corresponding slider and its mold to move radially out of the turntable to the use position; The turntable is also equipped with a cooling structure for cooling the mold when it is retracted to the storage position.

[0005] Furthermore, the coordinate driving mechanism includes two sets of parallel Y-axis driving mechanisms and an X-axis driving mechanism straddling the Y-axis driving mechanisms; the X-axis driving mechanism reciprocates along the Y-axis direction under the drive of the two sets of Y-axis driving mechanisms, and the driving block is mounted on the X-axis driving mechanism and reciprocates along the X-axis direction under its drive.

[0006] Furthermore, the upper surface of the mold platform is provided with an annular track, and the lower surface of the turntable is arranged in a circular array with multiple ball bearing mechanisms. Each ball bearing mechanism is embedded in the annular track and supports the turntable to rotate along the annular track.

[0007] Furthermore, the cooling structure includes heat dissipation fins, which are arranged in several layers and spaced apart along the axial direction.

[0008] Furthermore, the heat dissipation fins are provided with clearance notches at positions corresponding to the slider, the mold base, and the mold movement trajectory, and the heat dissipation fins cover the outside of the mold in a semi-enclosed shape when the slider retracts to the storage position.

[0009] Furthermore, multiple electrically controlled rollers are provided on the contact surface between the mold base and the mold. The electrically controlled rollers are used to drive the mold placed on the mold base to rotate around its own axis, so as to cooperate with the heat dissipation fins for uniform cooling.

[0010] Furthermore, the rapid mold change and uniform cooling structure also includes a fan controlled by the control system, the fan being positioned toward the heat dissipation fins.

[0011] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention achieves automatic mechanical capture and radial displacement of the mold through the cooperation of the coordinate drive mechanism, sleeve and inserting rod, avoiding the tedious process of manual mold disassembly and assembly, and shortening the downtime of the production line for mold replacement.

[0012] 2. This invention provides support and limits the turntable by setting a ring track and ball bearing mechanism at the bottom of the turntable. The rolling action of the balls within the track provides support and limits the turntable, thus improving the stability of the turntable when carrying heavy molds.

[0013] 3. By using layered heat dissipation fins and creating clearance notches on the fins, this invention maximizes the enclosure of the mold in the storage position without interfering with the movement of the slider and the mold, thereby increasing the contact area between the mold and the heat dissipation structure.

[0014] 4. This invention uses electrically controlled rollers to drive the mold in the storage position to rotate, so that all parts of the mold surface can have uniform heat exchange with the surrounding air and heat dissipation fins. This avoids the mold from deforming due to thermal stress caused by excessive local cooling, thereby protecting the mold's precision and extending its service life. Attached Figure Description

[0020] 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.

[0021] This invention discloses a rapid die-changing and uniform cooling structure for an aluminum profile extrusion die, mainly composed of two parts: a drive platform 100 and a die platform 200. For example... Figure 1 As shown, the drive platform 100 is located on one side of the mold platform 200, providing the mechanical power and spatial adjustment required for mold changing. A two-dimensional coordinate motion system consisting of two sets of Y-axis drive mechanisms 1 and one set of X-axis drive mechanisms 2 is mounted on the drive platform 100. The two sets of Y-axis drive mechanisms 1 are arranged parallel to each other, and the X-axis drive mechanism 2 straddles the two sets of Y-axis drive mechanisms 1, and is synchronously driven by the two sets of Y-axis drive mechanisms 1 to reciprocate along the Y-axis direction. A drive block 3 is mounted on the X-axis drive mechanism 2, and the drive block 3 can reciprocate along the X-axis direction under the drive of the X-axis drive mechanism 2. A sleeve 4 is horizontally fixed on the side of the drive block 3 facing the mold platform 200. Through the combined action of the Y-axis drive mechanism 1 and the X-axis drive mechanism 2, the sleeve 4 can be adjusted to any position in the X and Y axes of the horizontal plane, thereby achieving precise docking with the components on the mold platform 200.

[0022] like Figure 2 As shown, the mold platform 200 includes a support frame with a circular track 6 on its upper surface. A motor 5 is installed inside the support frame, which drives a turntable 7 located above the mold platform 200 to rotate. To ensure the stability of the turntable 7 when carrying a heavy-duty mold, as... Figure 3-4As shown, multiple ball bearing mechanisms 12 are arranged in a circular array on the lower surface of the turntable 7. The ball bearings of these ball bearing mechanisms 12 are embedded in the circular track 6. When the motor 5 drives the turntable 7 to rotate, each ball bearing mechanism 12 rolls along the circular track 6. This cooperation between the track and the balls serves two purposes: firstly, it limits the centripetal movement of the turntable 7, preventing the rotation center from shifting; secondly, it uses rolling friction instead of sliding friction, improving the load-bearing capacity and rotational stability of the turntable 7.

[0023] like Figure 3-4 As shown, four sliders 8 are arranged in a 90° circular array on the turntable 7. Of course, the number of sliders 8 is not limited to four; users can set the number according to their actual needs. Each slider 8 is mounted on a preset radial guide rail on the turntable 7, allowing it to slide back and forth in directions away from or towards the center point of the turntable 7. A horizontally extending insert rod 9 is fixed to the outer end of each slider 8. The length of the insert rod 9 is designed to ensure that its free end always extends beyond the edge of the turntable 7. The insert rod 9 is at the same height as the sleeve 4 on the drive platform 100. A mold holder 10 is fixedly mounted on the upper surface of the slider 8 for placing the mold 300 to be used. When a mold needs to be changed, the motor 5 drives the turntable 7 to rotate 90° or a multiple thereof, causing the slider 8 holding the target mold 300 to rotate to the side closer to the drive platform 100. At this time, the coordinate drive mechanism controls the sleeve 4 to move to a position coaxial with the insert rod 9 corresponding to the slider 8. Subsequently, the Y-axis drive mechanism 1 drives the sleeve 4 to approach and fit onto the insert rod 9. After the sleeve is installed, the coordinate drive mechanism continues to drive the sleeve 4 to pull it outward radially along the turntable 7, thereby moving the slider 8 and the die holder 10 outside the range of the turntable 7, so that the die 300 enters the working position of the extruder and is put into use (e.g. Figure 5 (As shown in the image). When it is necessary to switch back to the stored state, simply reverse the operation to retract slider 8 (as shown in the image). Figure 1 (The state shown).

[0024] In order to ensure uniform heat dissipation for mold 300 in its stored state, such as Figure 1 As shown, the central area of ​​the turntable 7 has several layers of heat dissipation fins 400. The heat dissipation fins 400 are arranged in layers at intervals along the axial direction, and each layer of heat dissipation fins 400 has a notch to avoid the movement paths of the sliders 8, the mold base 10, and the mold 300. When the sliders 8 are in the retracted state, the mold 300 is semi-enclosed by the layers of heat dissipation fins 400. Figure 3As shown, multiple electrically controlled rollers 11 are installed on the inner arc-shaped contact surface of the mold base 10. During heat dissipation, the electrically controlled rollers 11 are activated and drive the mold 300 to slowly rotate around its own axis. Through the continuous rotation of the mold 300, all parts of its surface can exchange heat with the heat dissipation fins 400 and the surrounding air in turn. With the help of an external fan, uniform cooling of the mold 300 as a whole is achieved, effectively avoiding thermal stress deformation of the mold caused by excessive local heat dissipation and extending the service life of the mold.

[0025] In summary, this invention precisely adjusts the spatial position of the sleeve 4 through a two-dimensional coordinate drive mechanism on the drive platform 100. Combined with the fixed-angle rotation positioning of the turntable 7, this achieves automatic docking and radial pulling between the sleeve 4 and the insert roller 9 on the slider 8, enabling rapid translational switching of the mold 300 between the storage and working positions, thus improving the level of automation. Simultaneously, the layered surrounding structure of the heat dissipation fins 400, in conjunction with the electrically controlled roller 11 driving the mold 300's rotation, ensures comprehensive heat exchange during the cooling process, guaranteeing uniform cooling, preventing mold thermal deformation, improving production accuracy, and extending equipment lifespan.

[0026] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
