Description

Technical Field

[0001] This utility model belongs to the field of tubular aluminum alloy profile processing, specifically a tubular aluminum alloy profile extrusion molding equipment. Background Technology

[0002] Aluminum tubes are a type of non-ferrous metal tube, referring to hollow metal tubular materials made from pure aluminum or aluminum alloys through extrusion, with one or more closed through holes. They have uniform wall thickness and cross-section, and are delivered in straight lines or coils. They are widely used in the automotive, shipbuilding, aerospace, aviation, electrical appliance, agriculture, electromechanical, and home furnishing industries. Aluminum tubes are mainly classified as follows: by shape (square, round, patterned, and special-shaped tubes, including Globe & Wheel aluminum tubes); by extrusion method (seamless and ordinary extruded tubes); by precision (ordinary and precision aluminum tubes, with precision aluminum tubes generally requiring further processing after extrusion, such as cold drawing and rolling); and by thickness (ordinary and thin-walled aluminum tubes).

[0003] In existing technologies, when aluminum ingots are pressed into aluminum tubes using molds, the formed aluminum tubes fit tightly with the molds, making it difficult to unload the aluminum tubes. Forceful disassembly can easily damage the aluminum tubes. Furthermore, the limiting effect on the aluminum ingots is not good when pressing them in the mold cavity, and the aluminum ingots are prone to shifting during the pressing process, resulting in uneven thickness of the formed aluminum tubes.

[0004] Therefore, this utility model provides a tubular aluminum alloy profile extrusion molding equipment. Utility Model Content

[0005] To overcome the shortcomings of existing technology, when using molds to press aluminum ingots into aluminum tubes, the formed aluminum tubes fit tightly with the molds, making it difficult to unload the aluminum tubes. Forceful disassembly can easily damage the aluminum tubes. Furthermore, when pressing the aluminum ingots in the mold cavity, the limiting effect on the aluminum ingots is not good, and the aluminum ingots are prone to displacement during the pressing process, resulting in uneven thickness of the formed aluminum tubes. This utility model proposes a tubular aluminum alloy profile extrusion forming equipment.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The tubular aluminum alloy profile extrusion forming equipment of this utility model includes a base, a bracket fixedly connected to the top of the base, a top plate fixedly connected to the top of the bracket, a hydraulic cylinder fixedly connected to the bottom of the top plate, an extrusion plate fixedly connected to the output end of the hydraulic cylinder, the extrusion plate being slidably connected to the bracket, an upper mold fixedly connected to the bottom of the extrusion plate, a lower mold fixedly connected to the top of the base, a mold cavity being opened on the top of the lower mold, and a material ejection assembly being provided on the top of the base.

[0007] Preferably, a limiting groove is formed at the bottom of the inner wall of the mold cavity, and an annular protrusion is fixedly connected to the bottom of the upper mold.

[0008] Preferably, the unloading assembly includes a support frame, which is fixedly installed on the top of the base. A limiting plate is fixedly connected to the top of the support frame, and a slot is provided inside the limiting plate, through which the upper mold passes.

[0009] Preferably, the limiting plate has a cavity inside, a liquid inlet valve is provided on the top of the limiting plate and the liquid inlet valve communicates with the cavity, and a feeding assembly is provided inside the limiting plate.

[0010] Preferably, the feeding assembly includes a plurality of sliding plates, each of which is disposed inside a limiting plate and slidably connected to the limiting plate. Each sliding plate has a receiving cavity inside, a feeding port at its top, and a second feeding port at its bottom. Both the feeding port and the second feeding port communicate with the receiving cavity. A first feeding port is located inside the limiting plate at the top of the cavity, above the feeding port. A spring is fixedly connected to one side of each sliding plate, with one end of the spring fixedly connected to the limiting plate. A wedge is fixedly connected to the other side of the sliding plate, with the top of the wedge forming an inclined surface.

[0011] Preferably, a third discharge port is provided inside the limiting plate and below the slide plate, and a guide groove is provided inside the limiting plate and below the third discharge port. The guide groove is inclined and one end of the guide groove extends into the interior of the slot.

[0012] The beneficial effects of this utility model are as follows: 1. The extrusion molding equipment for tubular aluminum alloy profiles described in this utility model, when the hydraulic cylinder controls the upper die to move downward to extrude aluminum ingots, the upper die passes through the slot. After the upper die finishes pressing the aluminum ingot, the formed aluminum tube is sleeved on the outside of the upper die. As the hydraulic cylinder controls the upper die to move upward, the formed aluminum tube is ejected from the outside of the upper die by the obstruction of the limiting plate. Through the setting of the limiting groove, when the aluminum ingot is pressed and deformed in the die cavity, the bottom of the aluminum ingot extends into the limiting groove, thereby making the stability of the aluminum ingot in the die cavity better and avoiding displacement during extrusion. When the upper die presses the aluminum ingot, the annular protrusion is inserted into the top of the aluminum ingot, thereby fixing the top of the aluminum ingot.

[0013] 2. In the tubular aluminum alloy profile extrusion forming equipment described in this utility model, when the upper die moves downward, the upper die pushes the inclined block to move under the extrusion of the upper die, which in turn drives the slide plate to move. This causes the second discharge port to move above the third discharge port. The lubricant in the receiving cavity enters the third discharge port along the second discharge port and is discharged into the slot along the guide groove. The lubricant discharged into the slot can be applied to the surface of the upper die to lubricate the upper die, reduce the friction between the upper die and the aluminum ingot, facilitate the upward extension of the aluminum ingot, and facilitate the downward ejection of the formed aluminum tube.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1 to 6As shown, this utility model provides a technical solution: an extrusion forming equipment for tubular aluminum alloy profiles, including a base 1, a support 2 fixedly connected to the top of the base 1, a top plate 3 fixedly connected to the top of the support 2, a hydraulic cylinder 4 fixedly connected to the bottom of the top plate 3, an extrusion plate 5 fixedly connected to the output end of the hydraulic cylinder 4, the extrusion plate 5 being slidably connected to the support 2, an upper mold 6 fixedly connected to the bottom of the extrusion plate 5, a lower mold 7 fixedly connected to the top of the base 1, a mold cavity 8 opened at the top of the lower mold 7, and a material ejection assembly provided at the top of the base 1.

[0018] The above technical solution involves placing an aluminum ingot in the mold cavity 8, activating the hydraulic cylinder 4 to move the extrusion plate 5 downwards, causing the upper mold 6 to move downwards and insert into the mold cavity 8. Through the extrusion of the upper mold 6, the aluminum ingot in the mold cavity 8 is deformed and extends upwards along the shape of the upper mold 6 to form an aluminum tube. After the aluminum tube is pressed and formed, the hydraulic cylinder 4 controls the extrusion plate 5 to move upwards, causing the upper mold 6 to move upwards. The ejection assembly then causes the formed aluminum tube to detach from the outside of the upper mold 6.

[0019] Specifically, a limiting groove 9 is provided at the bottom of the inner wall of the mold cavity 8, and an annular protrusion 10 is fixedly connected to the bottom of the upper mold 6.

[0020] Through the above technical solution, by setting the limiting groove 9, when the aluminum ingot is pressed and deformed in the mold cavity 8, the bottom of the aluminum ingot extends into the limiting groove 9, thereby making the stability of the aluminum ingot in the mold cavity 8 better and avoiding displacement due to extrusion. When the upper mold 6 presses the aluminum ingot, the annular protrusion 10 is inserted into the top of the aluminum ingot, thereby fixing the top of the aluminum ingot.

[0021] Specifically, the unloading assembly includes a support frame 11, which is fixedly installed on the top of the base 1. A limiting plate 12 is fixedly connected to the top of the support frame 11. A slot 13 is provided inside the limiting plate 12, and the upper mold 6 passes through the slot 13.

[0022] With the above technical solution, when the hydraulic cylinder 4 controls the upper mold 6 to move downward to squeeze the aluminum ingot, the upper mold 6 passes through the slot 13. After the upper mold 6 finishes pressing the aluminum ingot, the formed aluminum tube is sleeved on the outside of the upper mold 6. As the hydraulic cylinder 4 controls the upper mold 6 to move upward, the formed aluminum tube is ejected from the outside of the upper mold 6 by the obstruction of the limiting plate 12.

[0023] Specifically, the limiting plate 12 has a cavity 14 inside, and a liquid inlet valve 15 is provided at the top of the limiting plate 12, which communicates with the cavity 14. A feeding assembly is provided inside the limiting plate 12; the feeding assembly includes several sliding plates 16, all of which are disposed inside the limiting plate 12 and slidably connected to it. A receiving cavity 20 is provided inside each sliding plate 16, a feeding port 21 is provided at the top of each sliding plate 16, and a second feeding port 22 is provided at the bottom of each sliding plate 16. Both the feeding port 21 and the second feeding port 22 communicate with the receiving cavity 20. A first discharge port 19 is provided at the top of the cavity 14, which is located above the feed port 21. A spring 17 is fixedly connected to one side of the slide plate 16, and one end of the spring 17 is fixedly connected to the limiting plate 12. An inclined block 18 is fixedly connected to the other side of the slide plate 16, and the top of the inclined block 18 is set as an inclined surface. A third discharge port 23 is provided inside the limiting plate 12 and below the slide plate 16. A guide groove 24 is provided inside the limiting plate 12 and below the third discharge port 23. The guide groove 24 is opened at an angle, and one end of the guide groove 24 extends into the interior of the slot 13.

[0024] Through the above technical solution, lubricant is introduced into the cavity 14 via the inlet valve 15. The lubricant enters the receiving cavity 20 along the first discharge port 19 and the inlet port 21. When the upper mold 6 moves downward, its bottom presses against the inclined surface of the top of the inclined block 18. Under the pressure of the upper mold 6, the inclined block 18 is pushed to move, which in turn moves the slide plate 16 and compresses the spring 17. At the same time as the slide plate 16 moves, the second discharge port 22 moves accordingly, causing the second discharge port 22 to move above the third discharge port 23. The lubricant in the receiving cavity 20 flows along the second discharge port 19 and the inlet port 21. The material enters the third discharge port 23 through the inlet 22 and is discharged into the slot 13 along the guide groove 24. The lubricant discharged into the slot 13 can be applied to the surface of the upper mold 6 to lubricate the upper mold 6, reduce the friction between the upper mold 6 and the aluminum ingot, facilitate the upward extension of the aluminum ingot, and facilitate the downward ejection of the formed aluminum tube. After the upper mold 6 is retracted upward, the slide plate 16 is reset under the action of the spring 17. At this time, the feed port 21 moves again to the lower part of the first discharge port 19, so that the receiving cavity 20 can be reloaded, which facilitates lubrication when extruding the next aluminum ingot.

[0025] In use, the aluminum ingot is placed in the mold cavity 8, and the hydraulic cylinder 4 is activated, driving the extrusion plate 5 downwards. This causes the upper mold 6 to move downwards and insert into the mold cavity 8. Through the extrusion of the upper mold 6, the aluminum ingot in the mold cavity 8 is deformed and extends upwards along the shape of the upper mold 6, forming an aluminum tube. Through the set limiting groove 9, when the aluminum ingot is pressed and deformed in the mold cavity 8, the bottom of the aluminum ingot extends into the limiting groove 9, thereby improving the stability of the aluminum ingot in the mold cavity 8 and preventing displacement during extrusion. When pressing six pairs of aluminum ingots, the annular protrusion 10 is inserted into the top of the aluminum ingot, thereby fixing the top of the aluminum ingot. Lubricant is injected into the cavity 14 through the liquid inlet valve 15. The lubricant enters the receiving cavity 20 along the first discharge port 19 and the feed port 21. When the upper mold 6 moves downward, its bottom abuts against the inclined surface of the top of the inclined block 18. Under the pressure of the upper mold 6, the inclined block 18 is pushed to move, which drives the slide plate 16 to move and compresses the spring 17. At the same time as the slide plate 16 moves, the second discharge port 22 moves accordingly. The second discharge port 22 is moved above the third discharge port 23. The lubricant in the receiving chamber 20 flows along the second discharge port 22 into the third discharge port 23, and then along the guide groove 24 into the slot 13. The lubricant in the slot 13 can be applied to the surface of the upper mold 6, lubricating it and reducing the friction between the upper mold 6 and the aluminum ingot. This facilitates the upward extension of the aluminum ingot and the downward ejection of the formed aluminum tube. When the hydraulic cylinder 4 controls the upper mold 6 to move downward to extrude the aluminum ingot, the upper mold... 6 passes through the slot 13. After the upper mold 6 finishes pressing the aluminum ingot, the formed aluminum tube is sleeved on the outside of the upper mold 6. As the hydraulic cylinder 4 controls the upper mold 6 to move upward, the formed aluminum tube is pushed out of the upper mold 6 by the blocking of the limit plate 12. After the upper mold 6 is pulled back upward, the slide plate 16 is reset under the action of the spring 17. At this time, the feed port 21 moves again to the bottom of the first discharge port 19, so that the receiving cavity 20 can be reloaded, which is convenient for lubrication when pressing the next aluminum ingot.
