Description

Technical Field

[0001] This invention relates to the field of aluminum profile extrusion technology, and in particular to an aluminum profile extrusion press. Background Technology

[0002] Aluminum extrusion presses are the core equipment in the aluminum processing industry for achieving metal plastic forming. Their function is to apply mechanical pressure to extrude aluminum bars or ingots heated to a plastic state through a die of a specific shape, thereby obtaining aluminum profiles with precise cross-sectional shape, size and properties.

[0003] In the extrusion operation, the extrusion plate is slidably mounted on the moving plate via the moving extrusion seat. The moving plate drives the extrusion aluminum rod to move towards the ingot cylinder. At the same time, the extrusion plate is driven by the rack on the moving extrusion seat to adjust the position of the extrusion plate on the moving plate, so that the extrusion rod on the extrusion plate is aligned with the aluminum rod in the ingot cylinder.

[0004] During the extrusion process, the aluminum rod is squeezed while simultaneously exerting a reaction force on the pressure plate, causing the extrusion plate to move slightly backward. The rack on the moving extrusion seat is typically rigidly connected to the extrusion plate, so this slight backward movement of the extrusion plate causes one end of the rack to move backward as well. With repeated use, this can easily cause the rack to deform, shortening its lifespan. Summary of the Invention

[0005] Therefore, it is necessary to provide an aluminum profile extrusion press that can protect the rack on the moving extrusion seat, addressing the aforementioned technical problems.

[0006] This invention provides an aluminum profile extrusion press, comprising:

[0007] The frame has an X-axis track plate;

[0008] The movable plate is slidably mounted on the X-axis track plate;

[0009] The movable compression seat is mounted on the moving plate;

[0010] A billet holder, having an extrusion chamber, is slidably mounted on the X-axis track plate and is used to hold aluminum bars to be extruded;

[0011] An extrusion component having an extrusion rod slidably mounted on the movable extrusion seat for extruding an aluminum rod within the extrusion chamber;

[0012] The movable extrusion seat includes a drive source, a drive rack, and a universal head. One end of the drive rack is connected to the drive source, and the other end is equipped with the universal head.

[0013] The extrusion member has a connecting groove on its side wall adjacent to the drive source. The end of the universal head opposite to the drive rack is movably installed in the connecting groove. A rigid gasket and a flexible gasket are installed in the connecting groove. One side surface of the flexible gasket is in contact with the inner wall of the connecting groove facing the groove opening, and the surface of the flexible gasket facing the groove opening is in contact with the rigid gasket.

[0014] In one embodiment, the universal joint includes a ball joint and an adapter rod, the ball joint being installed in the connecting groove, one end of the adapter rod being connected to the ball joint, and the other end of the adapter rod extending to the outside of the connecting groove;

[0015] The connecting groove is cylindrical in shape, and the inner diameter of the connecting groove matches the outer diameter of the ball head.

[0016] In one embodiment, a pressure plate is installed on the side wall of the extruder. The pressure plate is detachable and is installed outside the opening of the connecting groove. The pressure plate is used to limit the universal head within the connecting groove.

[0017] In one embodiment, the pressure plate has a through hole on the surface corresponding to the connecting groove. The inner diameter of the through hole is larger than the outer diameter of the adapter rod. The through hole has an abutment portion near the corner of the connecting groove. The abutment portion is an arc-shaped inner chamfer that matches the ball head.

[0018] In one embodiment, the end of the adapter rod opposite to the ball head has a screw hole;

[0019] The drive rack has a connecting screw and a locking nut at one end near the ball head. The connecting screw is adapted to the screw hole, and the inner wall of the locking nut has a threaded surface that is consistent with the rotation direction of the screw hole.

[0020] In one embodiment, the extrusion member includes an extrusion plate, and the extrusion rod is mounted on the extrusion plate;

[0021] The extrusion rod includes a drive rod and an extrusion head. The drive rod is detachably mounted on the extrusion plate, and the extrusion head is fixedly mounted on the drive rod.

[0022] In one embodiment, the extrusion head has a sliding cavity, and a connecting rod is provided on the inner wall of one end of the sliding cavity adjacent to the drive rod, on which a cleaning component is slidably mounted;

[0023] The connecting rod has a translation groove and a spiral groove, which are arranged sequentially and connected along the direction from the drive rod to the extrusion head.

[0024] In one embodiment, the cleaning component includes a connecting sleeve and a connecting chuck, the connecting sleeve being slidably fitted onto the connecting rod, the inner wall of the connecting sleeve having a sliding post, and the connecting chuck being detachably installed at the end of the connecting sleeve opposite to the connecting rod;

[0025] In the initial state, the end of the sliding column opposite to the connecting sleeve is slidably installed in the spiral groove.

[0026] In one embodiment, the connecting chuck includes an outer circular plate and an inner sleeve. One end of the inner sleeve is detachably mounted on the end of the connecting sleeve opposite to the connecting rod, and the other end is fixedly connected to the outer circular plate. The axis of the inner sleeve coincides with that of the outer circular plate.

[0027] The outer arc wall of the outer circular plate has multiple sets of scraping claws, which are arranged in a circular array with the center of the outer circular plate as the center. The surface of the extrusion head away from the drive rod is provided with multiple sets of retraction grooves. The shape and number of the retraction grooves are matched with the scraping claws, and the retraction grooves are arranged in a circular array on the extrusion head.

[0028] In one embodiment, the ingot container has multiple sets of heating grooves arranged in a circular array, and multiple sets of straight-inserted heating wires are inserted into the heating grooves.

[0029] A temperature control probe is installed on the side wall of the ingot container, and the temperature control probe is used to detect the ambient temperature inside the ingot container.

[0030] Beneficial effects

[0031] Compared to the previous hard connection method with a T-shaped connection structure at the end of the drive rack, the above-mentioned aluminum profile extrusion press adopts a soft connection method with a universal head at the end of the drive rack. While ensuring that the universal head is closely connected to the extrusion plate, it allows the extrusion plate to swing slightly relative to the drive rack in the height and horizontal directions. This does not affect the accuracy of the drive rack in adjusting the position of the extrusion plate, and effectively extends the service life of the drive rack. Attached Figure Description

[0046] The following is combined with Figures 1-6 The aluminum profile extrusion press of the present invention is described.

[0047] like Figure 1 and Figure 2 As shown, in one embodiment, an aluminum profile extrusion press includes a frame 1, a moving plate 2, a movable extrusion seat 3, a billet cylinder 4, and an extruded part 5.

[0048] The frame 1 has an X-axis track plate 11.

[0049] The movable plate 2 is slidably mounted on the X-direction track plate 11.

[0050] The movable extrusion seat 3 is mounted on the moving plate 2.

[0051] The ingot container 4 has a compression chamber 41 (see Figure 6 It is slidably mounted on the X-axis track plate 11 and is used to hold the aluminum rod to be extruded.

[0052] The extrusion member 5 has an extrusion rod 51, which is slidably mounted on the movable extrusion seat 3 for extruding the aluminum rod in the extrusion chamber 41.

[0053] It should be noted that the movable extrusion seat 3 includes a Y-axis track plate, a movable slider, and a pad. The Y-axis track plate is mounted on the moving plate 2, the movable slider is mounted on the Y-axis track plate, and the pad is detachably mounted between the movable slider and the extrusion member 5. Preferably, the Y-axis track plate is bolted to the moving plate 2, and there are two sets of movable sliders symmetrically arranged on both sides of the X-axis centerline of the Y-axis track plate. Preferably, the pad is a copper plate.

[0054] It should be noted that one end of the extrusion rod 51 is detachably mounted on the extrusion piece 5, and the other end of the extrusion rod 51 extends towards the outside of the extrusion piece 5 in the direction of the ingot cylinder 4. The inner diameter of the extrusion chamber 41 matches the outer diameter of the outer end of the extrusion rod 51.

[0055] The movable extrusion seat 3 includes a drive source 31, a drive rack 32 and a universal head 33. One end of the drive rack 32 is connected to the drive source 31, and the other end is equipped with the universal head 33.

[0056] It should be noted that the drive source 31 includes a servo motor, a reducer, and a drive gear. The input end of the reducer is connected to the rotor of the servo motor, and the rotor at the output end of the reducer is fixedly connected to the drive gear. The drive gear meshes with the drive rack 32 for transmission.

[0057] The extrusion 5 has a connecting groove 52 on its side wall adjacent to the drive source 31 (see...). Figure 3 The universal head 33 is movably installed in the connecting groove 52 at one end away from the drive rack 32. A rigid gasket 52-1 and a flexible gasket 52-2 are installed in the connecting groove 52. One side surface of the flexible gasket 52-2 is in contact with the inner wall of the connecting groove 52 facing the groove opening, and the surface of the flexible gasket 52-2 facing the groove opening of the connecting groove 52 is in contact with the rigid gasket 52-1.

[0058] Preferably, the rigid gasket 52-1 is a steel plate, and the flexible gasket 52-2 is a reinforcing steel plate.

[0059] Specifically, when adjusting the position of the extruder 5 along the Y direction, the servo motor drives the drive gear to rotate through the reducer, the drive gear drives the drive rack 32 to move, and the drive rack 32 drives the extruder 5 to move through the universal head 33. During this process, the extruder 5 will apply a certain frictional force to the pad to drive the pad to move.

[0060] As the number of uses increases, the friction force exerted by the extruder 5 on the pad will cause wear on the pad, which in turn will cause the height of the extruder 5 to shift.

[0061] When the extruder 5 moves along the X direction to extrude the aluminum rod, the reaction force exerted by the aluminum rod on the extruder 5 will cause the extruder 5 to shift backward along the X direction.

[0062] By connecting the drive rack 32 and the pressing member 5 using the universal joint 33, when the pressing member 5 shifts in height or backward, it can swing relative to the universal joint 33 in the height and X directions to prevent one end of the drive rack 32 from being deformed by the displacement caused by the pressing member 5. Furthermore, during the swinging process of the pressing member 5 relative to the universal joint 33, the rigid gasket 52-1 is rigidly connected to the universal joint 33 to maintain a pressing effect on the universal joint 33, while the flexible gasket 52-2 provides floating space for the universal joint 33 to swing within the connecting groove 52.

[0063] like Figure 3 As shown, in one embodiment, the universal joint 33 includes a ball joint 33-1 and an adapter rod 33-2. The ball joint 33-1 is installed in the connecting groove 52, and one end of the adapter rod 33-2 is connected to the ball joint 33-1, while the other end extends to the outside of the connecting groove 52.

[0064] The connecting groove 52 is cylindrical in shape, and the inner diameter of the connecting groove 52 matches the outer diameter of the ball head 33-1.

[0065] In this embodiment, a pressure plate 53 is installed on the side wall of the extrusion member 5. The pressure plate 53 is detachable and is installed on the outside of the groove of the connecting groove 52. The pressure plate 53 is used to limit the universal head 33 in the connecting groove 52, and the pressure plate 53 and the rigid gasket 52-1 together press against the universal head 33.

[0066] In this embodiment, the surface of the pressure plate 53 corresponding to the connecting groove 52 has a through hole 53-1. The inner diameter of the through hole 53-1 is larger than the outer diameter of the adapter rod 33-2, providing displacement space for the adapter rod 33-2 to swing relative to the pressure plate 53. The corner of the through hole 53-1 adjacent to the connecting groove 52 has an abutment portion 53-11, which is an arc-shaped inner chamfer that matches the ball head 33-1.

[0067] Preferably, the extruder 5 has threaded holes along the edge of the connecting groove 52, and the pressure plate 53 is bolted to the side wall of the extruder 5. The pressure plate 53 is disc-shaped.

[0068] Specifically, under the thrust of the flexible gasket 52-2, the rigid gasket 52-1 abuts the ball head 33-1 against the abutting part 53-11 of the pressure plate 53.

[0069] In this embodiment, the end of the adapter rod 33-2 that is away from the ball head 33-1 has a screw hole;

[0070] The drive rack 32 has a connecting screw 32-1 and a locking nut 32-2 at one end near the ball head 33-1. The connecting screw 32-1 is adapted to the screw hole, and the inner wall of the locking nut 32-2 has a threaded surface that is consistent with the direction of rotation of the screw hole.

[0071] Specifically, when installing the ball head 33-1 onto the drive rack 32, first screw the locking nut 32-2 clockwise onto the connecting screw 32-1, then rotate the adapter rod 33-2 clockwise onto the connecting screw 32-1. Next, rotate the locking nut 32-2 counterclockwise to tighten it against the adapter rod 33-2. Since both the locking nut 32-2 and the adapter rod 33-2 need to be rotated counterclockwise to unscrew the connecting screw 32-1, friction exists between them. This increases the resistance to counterclockwise rotation of the adapter rod 33-2, thereby enhancing the thread locking effect between the adapter rod 33-2 and the connecting screw 32-1.

[0072] Because after the extrusion rod 51 completes the extrusion and separates from the aluminum rod, some aluminum shavings will remain on the outer wall of the end that is in contact with the aluminum rod. When the extrusion rod 51 extrudes the aluminum rod again, the residual shavings on the surface of the extrusion rod 51 will affect the surface flatness of the extruded aluminum material.

[0073] In this embodiment, the extrusion member 5 includes an extrusion plate 54 (see...). Figure 2 The extrusion rod 51 is mounted on the extrusion plate 54;

[0074] like Figure 4 and Figure 5 As shown, in one embodiment, the extrusion rod 51 includes a drive rod 51-1 and an extrusion head 51-2. The drive rod 51-1 is detachably mounted on the extrusion plate 54, and the extrusion head 51-2 is fixedly mounted on the drive rod 51-1.

[0075] In this embodiment, the extrusion head 51-2 has a sliding cavity 51-22, and the inner wall of one end of the sliding cavity 51-22 adjacent to the drive rod 51-1 has a connecting rod 51-23, and a cleaning component 55 is slidably installed on the connecting rod 51-23;

[0076] The connecting rod 51-23 has a translation groove 51-24 and a spiral groove 51-26. The translation groove 51-24 and the spiral groove 51-26 are arranged sequentially and connected along the direction from the drive rod 51-1 to the extrusion head 51-2.

[0077] In this embodiment, the cleaning component 55 includes a connecting sleeve 55-1 and a connecting chuck 55-2. The connecting sleeve 55-1 is slidably sleeved on the connecting rod 51-23. The inner wall of the connecting sleeve 55-1 has a sliding post 55-11. The connecting chuck 55-2 is detachably installed at one end of the connecting sleeve 55-1 away from the connecting rod 51-23.

[0078] In the initial state, the end of the sliding column 55-11 facing away from the connecting sleeve 55-1 is slidably installed in the spiral groove 51-26.

[0079] In this embodiment, the connecting chuck 55-2 includes an outer circular plate 55-22 and an inner sleeve 55-24. One end of the inner sleeve 55-24 is detachably installed on the end of the connecting sleeve 55-1 away from the connecting rod 51-23, and the other end is fixedly connected to the outer circular plate 55-22. The axis of the inner sleeve 55-24 coincides with that of the outer circular plate 55-22.

[0080] Preferably, the end of the connecting sleeve 55-1 opposite to the connecting rod 51-23 has a connecting rod with a connecting screw hole, and the inner sleeve 55-24 has a connecting hole. By fitting the inner sleeve 55-24 onto the connecting rod and aligning the connecting hole with the connecting screw hole, a screw is passed through the connecting hole and screwed into the connecting screw hole, thereby fixing the inner sleeve 55-24 together with the circular plate onto the connecting sleeve 55-1. This connection method facilitates the subsequent disassembly and replacement of the connecting chuck 55-2.

[0081] The outer arc wall of the outer circular plate 55-22 has multiple sets of scraper claws 55-21. The scraper claws 55-21 are arranged in a circular array with the center of the outer circular plate 55-22 as the center. The surface of the extrusion head 51-2 away from the drive rod 51-1 is provided with multiple sets of retraction grooves 51-21. The shape and number of the retraction grooves 51-21 match those of the scraper claws 55-21. The retraction grooves 51-21 are arranged in a circular array on the extrusion head 51-2.

[0082] Preferably, the spiral grooves 51-26 are one-third turns of spiral, the scraper claws 55-21 are in three groups, and the retraction grooves 51-21 are in three groups. Alternatively, the spiral grooves 51-26 are one-quarter turns of spiral, the scraper claws 55-21 are in four groups, and the retraction grooves 51-21 are in four groups.

[0083] Preferably, the scraper 55-21 includes a scraper strip and a stop plate. The stop plate is fixedly installed at the end of the scraper strip away from the inner sleeve 55-24, and the stop plate is perpendicular to the scraper strip. By setting the stop plate, the contact area between the extrusion head 51-2 and the aluminum rod is increased when they first come into contact, reducing the initial pressure on the aluminum rod when it is first extruded, and protecting the surface of the aluminum rod.

[0084] Specifically, when the extrusion rod 51 extrudes the aluminum rod in the ingot cylinder 4, the abutment plate first contacts the aluminum rod, and then the drive rod 51-1 continues to move, while the positions of the outer circular plate 55-22, the inner sleeve 55-24, and the connecting sleeve 55-1 remain unchanged, causing the sliding column 55-11 to begin sliding along the spiral groove 51-26. The sliding column 55-11 drives the connecting sleeve 55-1 to move synchronously, and the connecting sleeve 55-1 drives the outer circular plate 55-22 and the scraper 55-21 to move synchronously through the inner sleeve 55-24, causing the scraper 55-21 to adhere to the aluminum rod and rotate the outer circular plate 55-22, cleaning the aluminum shavings adhering to the contact surface between the aluminum rod and the outer circular plate 55-22.

[0085] When the sliding column 55-11 moves from the spiral groove 51-26 into the translation groove 51-24, the scraper 55-21 rotates to the position facing the retraction groove 51-21. As the sliding column 55-11 moves in the translation groove 51-24, the scraper 55-21 moves into the retraction groove 51-21 until the abutment plate is flush with the outer wall of the scraper and the outer wall of the extrusion head 51-2. At this time, the outer wall of the extrusion head 51-2 also abuts against the outer end of the aluminum rod. The extrusion head 51-2, the scraper 55-21 and the outer circular plate 55-22 are pushed together by the drive rod 51-1 to extrude the aluminum rod.

[0086] After the aluminum rod is extruded, the drive rod 51-1 pulls the extrusion head 51-2 to move in the opposite direction, so that the extrusion head 51-2 separates from the aluminum rod. During this process, the slide column 55-11 moves back from the translation groove 51-24 into the spiral groove 51-26. That is, the scraper 55-21 first moves out of the retraction groove 51-21, and then is driven to fit the extrusion head 51-2 and the aluminum rod to rotate in the opposite direction, so as to scrape off the residual debris on the extrusion head 51-2 in time and assist in smoothing and shaping the outer end surface of the aluminum rod.

[0087] Considering that when the aluminum profile extrusion press is used in low-temperature areas, a lot of heat is lost during the process of the aluminum rod being taken out of the heating furnace and transferred into the billet cylinder 4, and the material of the surface of the aluminum rod after cooling may change, affecting the extrusion effect.

[0088] like Figure 6 As shown, in one embodiment, the ingot cylinder 4 has multiple sets of heating grooves 42, which are arranged in a circular array. Multiple sets of straight-inserted heating wires 42-1 are inserted into the heating grooves 42, and the multiple sets of straight-inserted heating wires 42-1 are arranged in a circular array along the edge of the extrusion cavity 41.

[0089] A temperature control probe 43 is installed on the side wall of the ingot container 4. The temperature control probe 43 is used to detect the ambient temperature inside the ingot container 4.

[0090] Preferably, the temperature control probe 43 is a thermocouple or other sensors used for measuring temperature.

[0091] Specifically, the temperature control probe 43 monitors the ambient temperature inside the ingot cylinder 4 in real time and feeds the monitoring data back to the PLC system. The PLC system adjusts the working state of the direct-insertion heating wire 42-1 in real time according to the feedback to ensure that the ambient temperature inside the ingot cylinder 4 is within the specified temperature range, so as to heat and keep the aluminum rod inside the ingot cylinder 4 so that the aluminum profile extrusion press can be used in low-temperature areas.

[0092] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0093] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
