Description

Technical Field

[0001] This invention relates to the field of aluminum alloy processing technology, and in particular to a forming machine for aluminum alloy processing. Background Technology

[0002] Seamless aluminum alloy tube extrusion is a technology that directly produces finished tubes through extrusion. The principle is that aluminum billets are subjected to strong pressure in the mold cavity or extrusion cylinder, and are formed into tubes with the required cross-sectional shape, size and mechanical properties through the die hole of the extrusion mold.

[0003] Currently, aluminum alloy extrusion molding mostly adopts a single-mold, single-extrusion design mode. A single extrusion cycle can only complete the continuous forming of a single aluminum alloy tube. Due to limitations in equipment structure and mold configuration, it is impossible to achieve simultaneous extrusion of multiple tubes. Furthermore, the use of a fixed inner and outer mold structure, where the mold cavity size rigidly corresponds to the product specifications, makes it quite troublesome when adjusting the outer diameter and wall thickness of the tube. Summary of the Invention

[0004] To address the problems in the background art, the present invention provides a forming machine for aluminum alloy processing, which can simultaneously extrude two sets of aluminum alloy blocks into tubes, and supports the output aluminum alloy tubes through an inner support bracket and a lower support bracket. It also allows for the replacement of the inner and outer forming molds to change the inner and outer diameters of the extruded aluminum alloy tubes.

[0016] The lower cylinder is fixed on the processing table and has a semi-circular elongated hole inside, which is opposite to the front opening of the T-shaped frame. The upper cylinder also has a semi-circular elongated hole inside and is fixed to the lower cylinder with bolts. The top front end of the upper cylinder is also equipped with a front support frame, and three sets of cooling fans are embedded in the front support frame.

[0017] Furthermore, each of the four sets of inner support brackets is a semi-cylindrical structure with a circle in the middle. The inner diameter of the four sets of inner support brackets is the same as the inner diameter of the through hole in the middle of the outer mold. The rear ends of the two sets of inner support brackets are respectively provided with internal thread rings, which are screwed into the inner ring hole on the front end of the outer mold and connected to the thread on the inner side wall of the inner ring hole.

Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts.

[0055] Example 1: Please refer to Figures 1 to 12 :

[0056] This invention proposes a forming machine for aluminum alloy processing, comprising: a processing table 1, a T-shaped frame 2, a first electric cylinder 3, a forming inner mold 4, a second electric cylinder 6, an extrusion clamp 7, a forming outer mold 8, an inner support support 9, a lower support support 10, and an extrusion push rod 11.

[0060] Two sets of extrusion cylinders 7 are provided and are respectively set on the front opening side of the T-shaped frame 2, and the forming outer molds 8 are respectively placed on the front end of the inner side of the extrusion cylinders 7;

[0061] The inner support bracket 9 is provided in four sets. The rear ends of the two sets of inner support brackets 9 are connected to the outer mold 8 and placed on the rear end side of the lower support bracket 10. The two sets of inner support brackets 9 are placed on the front end side of the lower support bracket 10. The rear end of the lower support bracket 10 is connected to an arc-shaped connecting plate 1001 by bolts and inserted into the outer ring hole 801 on the front end side of the outer mold 8.

[0062] The lower support 10 is provided with extrusion push rods 11 on both sides, and the middle of the extrusion push rod 11 is connected to a threaded rod 1101. A threaded cylinder 1102 is threadedly engaged on the threaded rod 1101. The threaded cylinder 1102 is rotated and clamped on the processing table 1 to clamp the top of the support cylinder 102.

[0063] In embodiments of the present invention, such as Figure 8 As shown, the front end of the forming inner mold 4 is a conical structure and the rear end is a cylindrical structure. The forming inner mold 4 is threadedly connected to the threaded hole at the front end of the telescopic rod of the first electric cylinder 3 through the threaded post at the rear end. The forming inner mold 4 is replaced according to the required inner and outer diameters of the aluminum alloy tube in order to change the inner diameter of the aluminum alloy extruded tube.

[0064] In embodiments of the present invention, such as Figures 6 to 8As shown, a rear stop block 5 is installed on the front end side of the first electric cylinder 3. The rear end face of the rear stop block 5 is provided with four sets of inserts 501 and an upper limit plate 502. The rear stop block 5 is fitted onto the telescopic rod of the first electric cylinder 3 through the middle round hole, and is inserted into the insertion hole 301 on the front end face of the first electric cylinder 3 through the four sets of inserts 501. The rear stop block 5 limits the forward movement of the first electric cylinder 3, and restricts the rear end of the aluminum alloy block when the aluminum alloy block is extruded into a tube, so that the aluminum alloy block is only extruded into a tube through the gap between the outer forming mold 8 and the inner forming mold 4 by passing through the front end.

[0065] In embodiments of the present invention, such as Figure 7 As shown, the extrusion chuck 7 includes a lower cylinder 701 and an upper cylinder 702. The lower cylinder 701 is fixed on the processing table 1 and has a semi-circular elongated hole inside, which is opposite to the front opening of the T-shaped frame 2. The upper cylinder 702 also has a semi-circular elongated hole inside and is fixed to the lower cylinder 701 by bolts. A front support frame 7021 is also installed at the top front end of the upper cylinder 702, and three sets of heat dissipation fans 7022 are embedded in the front support frame 7021. This facilitates the disassembly of the extrusion chuck 7 and the replacement of the forming outer mold 8 to change the outer diameter of the aluminum alloy extruded tube. At the same time, the heat dissipation fans 7022 can also dissipate heat during the extrusion of the aluminum alloy tube.

[0066] In embodiments of the present invention, such as Figures 9 to 12 As shown, the four sets of inner support brackets 9 are semi-cylindrical structures with a circle in the middle. The inner diameter of the four sets of inner support brackets 9 is the same as the inner diameter of the through hole in the middle of the outer mold 8. The rear ends of the two sets of inner support brackets 9 are respectively provided with internal thread rings 901, which are screwed into the inner ring hole 802 on the front end of the outer mold 8 and connected to the thread on the inner wall of the inner ring hole 802. The inner support brackets 9 are respectively provided with outer connecting plates 902 on both sides of the middle circle. The outer connecting plates 902 are slidably inserted with pins 903. The lower end of the pins 903 is fitted with a spring 9032 and connected to a limit plate 9031. The rear ends of the lower support bracket 10 and the arc-shaped connecting plate 1001 are respectively provided with arc-shaped inserts. The outer diameter of the arc-shaped inserts is the same as that of the lower support bracket. 10. The outer diameter of the arc-shaped connecting plate 1001 is the same, and the inner diameter is smaller than that of the lower support bracket 10 and the arc-shaped connecting plate 1001. The arc-shaped insert plate is inserted into the outer ring hole 801 of the forming outer mold 8. The inner side of the lower support bracket 10 is also provided with two sets of arc-shaped slots 1002, and arc-shaped blocks 1003 are inserted into the arc-shaped slots 1002. When the inner support bracket 9 is placed inside the lower support bracket 10, the lower end of the pin 903 is inserted into the arc-shaped block 1003. The bottom front end of the lower support bracket 10 is also equipped with a support wheel 1004, which can make the inner support bracket 9, the lower support bracket 10 and the forming outer mold 8 integrated. Driven by the drive motor 12, and pushed by the extrusion push rod 11, the inner support bracket 7 can be extruded and moved inside or outwards simultaneously.

[0067] In embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the two ends of the extrusion push rod 11 are respectively inserted into the rear support cylinder 101 and the L-shaped guide cylinder 7011 at the front end of the lower cylinder 701 on the processing table 1, and the front stop block 1005 at the front end of the lower support support 10. The rear end of the extrusion push rod 11 is in contact with the lower support support 10 and the outer end of the arc-shaped connecting plate 1001, which can guide and support the extrusion push rod 11. The extrusion push rod 11 is also provided with an outer push plate 1103, and the front end of the outer push plate 1103 is in contact with the rear end of the front stop block 1005. By causing the drive motor 12 to rotate in the opposite direction, the threaded cylinder 1102 is driven to rotate in the opposite direction, causing the extrusion push rod 11 to move outward. The outer push plate 1103 pushes the front stop block 1005, and under the action of the arc-shaped clamping block 1003 and the pin 903, the inner support support 9 is driven to move outward simultaneously. At the same time, under the action of the inner threaded ring 901, the outer mold 8 is driven to move synchronously to extrude the next set of aluminum alloy tubes.

[0068] In embodiments of the present invention, such as Figure 2 As shown, the threaded cylinder 1102 is connected to the lower linkage shaft 1021 installed at the lower end of the clamping support cylinder 102 via chain drive, and the lower linkage shafts 1021 on both sides of the lower support bracket 10 are also connected via chain drive. One set of lower linkage shafts 1021 is also connected to the motor shaft of the drive motor 12 on the processing table 1 via chain drive. The drive motor 12 drives the threaded cylinder 1102 to rotate, and drives the threaded cylinder 1102 on the other side to rotate via the lower linkage shaft 1021. Through the cooperation between the threaded cylinder 1102 and the threaded rod 1101, the extrusion push rod 11 moves toward the inside of the extrusion clamping cylinder 7. When the drive motor 12 rotates in the opposite direction, it drives the threaded cylinder 1102 to rotate in the opposite direction, causing the extrusion push rod 11 to move outward.

[0069] The specific usage and function of this embodiment: In this invention,

[0070] First, according to the required inner and outer diameters of the aluminum alloy tube, the inner forming mold 4 is replaced, the extrusion clamp 7 is disassembled, and the outer forming mold 8 is replaced. By making the inner and outer diameters of the extruded aluminum alloy tube consistent with the outer diameter of the rear end of the inner forming mold 4 and the through hole in the middle of the outer forming mold 8, the inner and outer diameters of the aluminum alloy tube meet the required requirements.

[0071] After the heated aluminum alloy block is placed on the feeding inclined support 202, the aluminum alloy block can automatically roll down to the bottom of the T-shaped frame 2 by utilizing the inclined structure of the feeding inclined support 202. The second electric cylinder 6 drives the two sets of first electric cylinders 3 and the forming inner mold 4 to push the aluminum alloy block into the extrusion chuck 7, and the upper limit plate 502 on the rear stop block 5 clamps the position of the first electric cylinder 3.

[0072] Then, the first electric cylinder 3 pushes the inner forming mold 4 through the aluminum alloy block to the middle through hole of the outer forming mold 8. The drive motor 12 drives the threaded cylinder 1102 to rotate, and the lower linkage shaft 1021 drives the threaded cylinder 1102 on the other side to rotate. Through the cooperation of the threaded cylinder 1102 and the threaded rod 1101, the extrusion push rod 11 moves towards the inside of the extrusion chuck 7, which in turn drives the lower support support 10 and the outer forming mold 8 to move towards the inside of the extrusion chuck 7, extruding the aluminum alloy block into an aluminum alloy tube. The inner support support 9 and the lower support support 10 support the output aluminum alloy tube. The cooling fan 7022 at the front end of the top side of the upper cylinder 702 dissipates heat from the extruded aluminum alloy tube.

[0073] By causing the drive motor 12 to rotate in the opposite direction, the threaded cylinder 1102 rotates in the opposite direction, causing the extrusion push rod 11 to move outward. The outer push plate 1103 pushes the front stop block 1005, and under the action of the arc-shaped clamping block 1003 and the pin 903, the inner support bracket 9 moves outward synchronously. At the same time, under the action of the inner threaded ring 901, the outer forming mold 8 moves synchronously to extrude the next set of aluminum alloy tubes.
