Description

Technical Field

[0001] This invention belongs to the field of aluminum profile extrusion technology, specifically an aluminum profile extrusion press. Background Technology

[0002] Aluminum profile extrusion is a process in which pressure is applied to a heated aluminum rod and fed into a die to extrude the rod into the desired shape. Existing aluminum profile extrusion equipment generally includes a conveying structure, a heating structure, and an extrusion structure. The extrusion structure includes an extrusion die and a push rod for applying pressure to the aluminum rod.

[0003] A patent application with publication number CN118268399A discloses an aluminum profile extrusion equipment, including a support table, a heating device, a cutting device, a lifting device, and an extrusion device. The mounting table is located on the top surface of the support table, and the surface of the mounting table is equipped with a heating device, which has a feed inlet and a discharge outlet. This equipment shortens the distance of conveying the heated and cut aluminum billet to the extrusion station, reduces the impact on the plasticity of the aluminum billet, and improves the extrusion effect.

[0004] The above-mentioned solution still has some problems in practical application. When extruding aluminum rods with the above-mentioned equipment, in order to remove oil and impurities from the surface of the aluminum rod and ensure good contact between the die and the aluminum rod during the extrusion process, a degreasing agent is applied to the surface of the aluminum rod after heating. However, due to the excessive temperature of the aluminum rod surface, the application work is very difficult. Moreover, the heated aluminum rod will reduce its strength and rigidity and needs to be sent to the extrusion in time. If the application time is too long and it is not sent to the extrusion in time, the reduction in the strength and rigidity of the aluminum rod may be more significant, and the size and shape of the aluminum rod may change, such as the length increasing and the diameter increasing, which will lead to difficulties in subsequent processing.

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] Example 1

[0033] like Figures 1 to 9As shown, an aluminum profile extrusion press according to an embodiment of the present invention includes a base frame 3, a transfer structure 2 at the upper end of the base frame 3, the transfer structure 2 including a conveying roller 24, a heating furnace 4 at one end of the transfer structure 2, a pushing structure 5 at one end of the heating furnace 4, a pushing structure 5 including a pushing frame 51, a sliding rod 55 slidably connected inside the pushing frame 51, a temporary storage frame 53 slidably connected at one end of the pushing frame 51, a coating structure 7 at the end of the pushing frame 51 near the heating furnace 4, and an extrusion structure 6 at the lower end of the heating furnace 4; the extrusion structure 6 includes: an extrusion table 61 located at the lower end of the heating furnace 4; a conveying trough 62 located inside the extrusion table 61; and an extrusion die 63. 63 is located on the inner wall of the conveying trough 62; the coating structure 7 includes: an oil storage frame 701, which is located on the surface of the pushing frame 51; a transfer tube 704, with several transfer tubes 704 located at the lower end of the oil storage frame 701; a sliding strip 710, which is slidably connected to the inside of the transfer tube 704; a sliding groove 712, which is opened inside the transfer tube 704; a nozzle 716, which is located at the lower end of the sliding groove 712; a plug 711, which is slidably connected to the inner wall of the sliding groove 712 and is connected to the sliding strip 710; and an abutment block 705, which is located at one end of the sliding strip 710 and contacts the abutment block 705 after the temporary storage frame 53 moves upward.

[0034] Specifically, this aluminum profile extrusion press is mainly used to extrude aluminum rods 8 into aluminum profiles. In operation, the aluminum rod 8 is first placed on the surface of the conveyor roller 24. The conveyor roller 24 is then started to rotate, moving the aluminum rod 8 into the heating furnace 4. The heating furnace 4 then heats the aluminum rod 8. Heating changes the crystal structure of the aluminum, thereby reducing the hardness and strength of the aluminum rod 8 and increasing its plasticity. This makes it easier to shape the aluminum rod 8 into the desired form during extrusion. Subsequently, the temporary storage frame 53 is moved upwards until it is flush with the aluminum rod 8, after which the aluminum rod 8 is transferred to the temporary storage area. Inside frame 53, the temporary storage frame 53 is activated again and moves downward. When the temporary storage frame 53 moves the aluminum rod 8 to be level with the sliding rod 55, the sliding rod 55 is activated. The sliding rod 55 moves towards the aluminum rod 8 and pushes it into the conveying trough 62. As the sliding rod 55 presses one end of the aluminum rod 8, it can be formed into the desired shape through the extrusion die 63, thus completing the extrusion of the aluminum profile. The extruded aluminum profile will pass through the other end of the extrusion die 63 for collection. However, to ensure good contact between the extrusion die 63 and the aluminum rod 8 during the extrusion process and to reduce friction and resistance, the aluminum rod 8 will be heated... A degreasing agent is applied to the surface of the aluminum rod 8 to remove oil and impurities. A coating structure 7 is provided for this purpose. When the heated aluminum rod 8 moves into the interior of the temporary storage frame 53, a degreasing agent specifically for aluminum alloys is injected into the oil storage frame 701. The temporary storage frame 53 is then moved upwards a short distance. At this point, the upper surface of the temporary storage frame 53 will contact the abutment block 705, causing the abutment block 705 to move upwards a short distance. The abutment block 705 will then move the plug 711 along with the sliding bar 710, thereby opening the channel between the nozzle 716 and the transfer tube 704. Furthermore, due to the sliding bar 710... If the length is too long, the sealing of the side wall of the transfer tube 704 can be maintained when the abutment block 705 drives the sliding bar 710 to move upward. Then the degreasing agent will be discharged from the nozzle 716 and sprayed onto the surface of the aluminum rod 8. After the spraying is completed, the temporary storage frame 53 is moved downward again to extrude the aluminum rod 8. At this time, the abutment block 705 will not be abutted by the temporary storage frame 53 and will move downward through the sliding bar 710 to reset. By setting the coating structure 7, after the aluminum rod 8 is heated, the degreasing agent can be applied to the surface of the aluminum rod 8 during the transfer process without affecting the timely extrusion of the aluminum rod 8.

[0035] like Figures 1 to 9As shown, the transfer structure 2 has a conveying frame 1 at one end, and a conveyor belt 11 on the surface of the conveying frame 1; the transfer structure 2 also includes: a sliding block 21, which is slidably connected to the upper end of the base frame 3; an abutment piece 22, which is located at one end of the sliding block 21; a lifting platform 23, which is slidably connected to the upper end of the base frame 3, and a conveying roller 24 is located inside the lifting platform 23; the pushing structure 5 also includes: a lifting frame 52, which is slidably connected to one end of the pushing frame 51, and the lifting frame 52 is connected to the temporary storage frame 53; a telescopic cylinder 54, which is located at one end of the pushing frame 51, and the telescopic cylinder 54 controls the sliding rod 55 to slide; the coating structure 7 also includes: an abutment strip 714, which is located at the upper end of the temporary storage frame 53.

[0036] Specifically, when extruding aluminum rod 8 into aluminum profile, aluminum rod 8 is first placed on the surface of conveyor belt 11, then conveyor belt 11 is started, and conveyor belt 11 will move aluminum rod 8 into the interior of lifting platform 23 and into contact with conveyor roller 24. Then lifting platform 23 is started to move upward, and lifting platform 23 will move aluminum rod 8 to be flush with abutting plate 22. Then sliding block 21 is started, sliding block 21 will move abutting plate 22 together, and abutting plate 22 will transfer aluminum rod 8 into the interior of heating furnace 4.

[0037] like Figures 1 to 8 As shown, the oil storage frame 701 has a dividing plate 703 inside, and a pressing plate 708 is slidably connected inside the oil storage frame 701, and the pressing plate 708 is in contact with the side of the dividing plate 703 away from the transfer tube 704.

[0038] Specifically, by setting up the extrusion plate 708, when it is necessary to spray the degreasing agent inside the oil storage frame 701 from the nozzle 716, the extrusion plate 708 is activated. The extrusion plate 708 will move along the surface of the dividing plate 703, thereby increasing the pressure inside the oil storage frame 701 and squeezing the degreasing agent into the cavity near the transfer pipe 704, so that the degreasing agent can be sprayed out from the nozzle 716 more quickly.

[0039] like Figures 1 to 8 As shown, a rotating gear 706 is rotatably connected inside the push frame 51, and a telescopic rack 707 is slidably connected inside the push frame 51. The rotating gear 706 meshes with the telescopic rack 707, and the telescopic rack 707 is connected to the extrusion plate 708.

[0040] Specifically, by setting a rotating gear 706, when it is necessary to spray the degreasing agent inside the oil storage frame 701 from the nozzle 716, the rotating gear 706 is activated, and the rotating gear 706 will drive the telescopic rack 707 to move. Since the telescopic rack 707 is connected to the extrusion plate 708, the extrusion plate 708 will also be driven to move together at this time.

[0041] like Figures 1 to 8 As shown, the upper end of the lifting frame 52 is provided with a connecting rack 702, and the connecting rack 702 meshes with the rotating gear 706 after moving upward.

[0042] Specifically, by setting the connecting rack 702, during the process of the lifting frame 52 driving the temporary frame 53 to move upward, the lifting frame 52 will also drive the connecting rack 702 to move upward and mesh with the rotating gear 706, causing the rotating gear 706 to rotate, and finally causing the extrusion plate 708 to move.

[0043] Example 2

[0044] like Figure 9 As shown in the first embodiment, another embodiment of the present invention is as follows: the lower end of the sliding bar 710 is provided with a reset spring 713, and the other end of the reset spring 713 is connected to the transfer tube 704.

[0045] Specifically, by setting a reset spring 713, when the degreasing agent spraying is completed and the temporary storage frame 53 moves downward, the reset spring 713 will release its elastic force, thereby driving the sliding bar 710 and the plug 711 to reset.

[0046] like Figures 1 to 3 As shown, the upper end of the lifting platform 23 is provided with a dividing strip 25.

[0047] Specifically, by setting the dividing strip 25, when the lifting platform 23 moves upward, the dividing strip 25 will separate the aluminum rods 8 on the surface of the conveyor belt 11, thereby ensuring that there is only one aluminum rod 8 inside the lifting platform 23.

[0048] like Figure 4 As shown, an air gun 709 is provided at one end of the extrusion table 61 near the push frame 51.

[0049] Specifically, by setting up an air gun 709, when the aluminum rod 8 moves into the extrusion table 61 for extrusion, the air gun 709 is activated, and the air gun 709 will blow away the debris generated during extrusion, thereby preventing these debris from entering the extrusion mold 63 along with the aluminum rod 8 and affecting the extrusion effect.

[0050] like Figure 9 As shown, the transfer tube 704 is equipped with a filter screen 715 inside, and the filter screen 715 is located at the upper end of the plug 711.

[0051] Specifically, by setting up filter 715, the degreasing agent can be filtered, thereby preventing impurities inside the degreasing agent from being coated onto the surface of the aluminum rod 8.

[0052] like Figure 9As shown, the upper end of the plug 711 is provided with a pressure strip 717, and the pressure strip 717 is in contact with the filter screen 715.

[0053] Specifically, by setting the pressure strip 717, as the stopper 711 moves upward, the stopper 711 will drive the pressure strip 717 to move together, so that the pressure strip 717 passes through the holes on the surface of the filter screen 715. Since the diameter of the pressure strip 717 is smaller than the diameter of the holes on the surface of the filter screen 715, it can not only prevent the filter screen 715 from being blocked, but also will not affect the transfer of the degreasing agent.

[0054] Working Principle: In operation, the aluminum rod is first placed on the surface of the conveyor belt. The conveyor belt is then started, moving the aluminum rod to the inside of the lifting platform where it contacts the conveyor rollers. The lifting platform then moves upwards, moving the aluminum rod until it is flush with the contact plate. Next, the sliding block is activated, moving the contact plate along with the rod, which then transfers the aluminum rod into the heating furnace. The heating furnace then heats the aluminum rod. Heating changes the crystal structure of the aluminum, reducing its hardness and strength while increasing its plasticity. This makes the aluminum rod easier to shape into the desired form during extrusion. The temporary storage frame then moves upwards until it is flush with the aluminum rod, transferring it into the frame. Finally, the temporary storage frame... The temporary storage frame moves upward a certain distance, at which point the upper surface of the temporary storage frame will contact the abutment block, causing the abutment block to move upward a certain distance. The abutment block will then move the plug along with the sliding bar, thereby opening the channel between the nozzle and the transfer tube. Due to the excessive length of the sliding bar, the side wall of the transfer tube can be kept sealed while the abutment block moves the sliding bar upward. Subsequently, the degreasing agent will be discharged from the nozzle and sprayed onto the surface of the aluminum rod. After spraying is completed, the temporary storage frame is moved downward again. When the temporary storage frame moves the aluminum rod to be level with the sliding rod, the sliding rod is activated. The sliding rod will move towards the aluminum rod and push the aluminum rod into the inside of the conveying trough. As the sliding rod presses one end of the aluminum rod, it can be formed into the required shape by the extrusion die, thereby completing the extrusion of the aluminum profile.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
