Description

Technical Field

[0001] The invention belongs to the technical field of aluminum profile extrusion, in particular to an aluminum profile extruder. Background Art

[0002] Aluminum profile extrusion is the process of applying pressure to a heated aluminum rod and passing it into a mold to extrude the aluminum rod into a desired shape. Existing aluminum profile extrusion equipment generally includes a conveying structure, a heating structure, and an extrusion structure, wherein the extrusion structure includes an extrusion mold and a push rod for applying pressure to the aluminum rod.

[0003] A patent application with publication number CN118268399A discloses 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 arranged on the top surface of the support table, and a heating device is arranged on the surface of the mounting table. The heating device has a feed port and a discharge port. The equipment shortens the distance for conveying the heated and cut aluminum billet to the extrusion station, reduces the influence on the plasticity of the aluminum billet, and improves the extrusion effect.

[0004] There are still some problems in the actual application of the above scheme. When the aluminum rod is extruded with the above equipment, in order to remove oil and impurities on the surface of the aluminum rod and ensure good contact between the mold and the aluminum rod during the extrusion process, a layer of degreasing agent will be applied to the surface after the aluminum rod is heated. However, due to the excessively high temperature on the surface of the aluminum rod, the application work is very difficult, and the heated aluminum rod will reduce the strength and rigidity of the aluminum rod, so it needs to be sent to extrusion in time. If the application time is too long and the rod is not sent to extrusion in time, the reduction in strength and rigidity of the aluminum rod may be more significant, and the size and shape of the aluminum rod may change, such as increasing length and increasing diameter, which will lead to subsequent processing difficulties.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] Embodiment 1 like Figures 1 to 9As shown, an aluminum profile extruder according to an embodiment of the present invention comprises a base frame 3, a transfer structure 2 is provided at the upper end of the base frame 3, the transfer structure 2 comprises a conveying roller 24, a heating furnace 4 is provided at one end of the transfer structure 2, a pushing structure 5 is provided at one end of the heating furnace 4, the pushing structure 5 comprises a pushing frame 51, a sliding rod 55 is slidably connected inside the pushing frame 51, a temporary storage frame 53 is slidably connected at one end of the pushing frame 51, a coating structure 7 is provided at one end of the pushing frame 51 close to the heating furnace 4, and an extrusion structure 6 is provided at the lower end of the heating furnace 4; the extrusion structure 6 comprises: an extrusion table 61, the extrusion table 61 is provided at the lower end of the heating furnace 4; a conveying trough 62, the conveying trough 62 is opened inside the extrusion table 61; an extrusion die 63, an extrusion die 63 is arranged on the inner wall of the conveying groove 62; the smearing structure 7 includes: an oil storage frame 701, the oil storage frame 701 is arranged on the surface of the pushing frame 51; a transfer tube 704, a plurality of transfer tubes 704 are arranged at the lower end of the oil storage frame 701; a sliding bar 710, the sliding bar 710 is slidably connected to the inside of the transfer tube 704; a sliding groove 712, the sliding groove 712 is opened in the inside of the transfer tube 704; a nozzle 716, the nozzle 716 is arranged at the lower end of the sliding groove 712; a plug 711, the plug 711 is slidably connected to the inner wall of the sliding groove 712, and the plug 711 is connected to the sliding bar 710; an abutment block 705, the abutment block 705 is arranged at one end of the sliding bar 710, and the temporary storage frame 53 contacts the abutment block 705 after moving upward.

[0023] Specifically, an aluminum profile extruder of the scheme is mainly used to extrude an aluminum rod 8 into an aluminum profile. When in use, the aluminum rod 8 is first placed on the surface of the conveying roller 24, and the conveying roller 24 is started to rotate. The conveying roller 24 will drive the aluminum rod 8 to move to the inside of the heating furnace 4, and then the heating furnace 4 is started to heat the aluminum rod 8. Through heating, the crystal structure of aluminum changes, thereby reducing the hardness and strength of the aluminum rod 8 and improving the plasticity, which makes it easier for the aluminum rod 8 to be shaped into a desired shape during the extrusion process. Then, the temporary storage frame 53 is started to move upward, and the temporary storage frame 53 will move upward to be flush with the aluminum rod 8, and then the aluminum rod 8 is transferred to the temporary storage. The temporary frame 53 is moved inside, and the temporary frame 53 is started to move downward again. When the temporary frame 53 drives the aluminum rod 8 to move flush with the sliding rod 55, the sliding rod 55 is started, and the sliding rod 55 will move in the direction of the aluminum rod 8 and push the aluminum rod 8 into the inside of the conveying trough 62. As the sliding rod 55 presses one end of the aluminum rod 8, the desired shape can be formed through the extrusion die 63, thereby completing the extrusion of the aluminum profile, and the extruded aluminum profile will pass through the other end of the extrusion die 63 for collection. However, in order to ensure good contact between the extrusion die 63 and the aluminum rod 8 during the extrusion process and reduce friction and resistance, the aluminum rod 8 will be heated after heating. A degreasing agent is applied to the surface to remove oil stains and impurities on the surface of the aluminum rod 8. For this purpose, a coating structure 7 is provided. When the heated aluminum rod 8 moves to the inside of the temporary storage frame 53, a degreasing agent is poured into the inside of the oil storage frame 701. The degreasing agent is a special degreasing agent for aluminum alloy. Then the temporary storage frame 53 is moved upward for a distance again. At this time, the upper surface of the temporary storage frame 53 will contact the abutment block 705 and drive the abutment block 705 to move upward for a distance. The abutment block 705 will drive the plug 711 to move together through the sliding bar 710, thereby opening the channel between the nozzle 716 and the transfer pipe 704, and due to the sliding bar 710 If the length is too long, when the abutment block 705 drives the sliding bar 710 to move upward, the sealing of the side wall of the transfer tube 704 can always be guaranteed, and then the degreasing agent will flow out from the nozzle 716 and spray onto the surface of the aluminum rod 8. After the spraying is completed, the temporary storage frame 53 is started to move downward again, and the aluminum rod 8 can be extruded. At this time, the abutment block 705 no longer has the abutment of the temporary storage frame 53, and will drive the plug 711 to move downward through the sliding bar 710 to reset. By setting the smearing structure 7, after the aluminum rod 8 is heated, not only can the degreasing agent be applied to the surface of the aluminum rod 8 during the transportation process, but it will not affect the timely extrusion of the aluminum rod 8.

[0024] like Figures 1 to 9As shown, a conveying frame 1 is provided at one end of the transfer structure 2, and a conveying belt 11 is provided 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 sheet 22, which is arranged 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 arranged 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 arranged at one end of the pushing frame 51, and the telescopic cylinder 54 controls the sliding of the sliding rod 55; the smearing structure 7 also includes: an abutment strip 714, which is arranged at the upper end of the temporary storage frame 53.

[0025] Specifically, when the aluminum rod 8 is extruded into an aluminum profile, the aluminum rod 8 is first placed on the surface of the conveyor belt 11, and then the conveyor belt 11 is started. The conveyor belt 11 will drive the aluminum rod 8 to move to the inside of the lifting platform 23 and contact with the conveying roller 24. Then the lifting platform 23 is started to move upward, and the lifting platform 23 will drive the aluminum rod 8 to move flush with the abutment plate 22. Then the sliding block 21 is started, and the sliding block 21 will drive the abutment plate 22 to move together, and the abutment plate 22 will transfer the aluminum rod 8 to the inside of the heating furnace 4.

[0026] like Figures 1 to 8 As shown, a partition plate 703 is provided inside the oil storage frame 701 , and a pressing plate 708 is slidably connected inside the oil storage frame 701 , and the pressing plate 708 is in contact with a side of the partition plate 703 away from the transfer pipe 704 .

[0027] Specifically, by setting the extrusion plate 708, when the degreasing agent inside the oil storage frame 701 needs to be sprayed out from the nozzle 716, the extrusion plate 708 is started and the extrusion plate 708 will move along the surface of the partition plate 703, thereby increasing the pressure inside the oil storage frame 701 and squeezing the degreasing agent into the cavity close to the transfer pipe 704, ultimately allowing the degreasing agent to be sprayed out from the nozzle 716 faster.

[0028] like Figures 1 to 8 As shown, the pushing frame 51 is internally rotatably connected with a rotating gear 706 , the pushing frame 51 is internally slidably connected with a telescopic rack 707 , and the rotating gear 706 is meshed with the telescopic rack 707 , and the telescopic rack 707 is connected to the extrusion plate 708 .

[0029] Specifically, by setting the rotating gear 706, when the degreasing agent inside the oil storage frame 701 needs to be sprayed out from the nozzle 716, the rotating gear 706 is started, 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.

[0030] like Figures 1 to 8 As shown, a connecting rack 702 is provided at the upper end of the lifting frame 52, and the connecting rack 702 is meshed with the rotating gear 706 after moving upward.

[0031] Specifically, by setting the connecting rack 702, when the lifting frame 52 drives the temporary storage frame 53 to move upward, the lifting frame 52 will also drive the connecting rack 702 to move upward and engage with the rotating gear 706, so that the rotating gear 706 rotates, and finally the extrusion plate 708 moves.

[0032] Embodiment 2 like Fig. 9 As shown, compared with Example 1, another implementation of the present invention is: a return spring 713 is provided at the lower end of the sliding bar 710, and the other end of the return spring 713 is connected to the transfer tube 704.

[0033] Specifically, by providing the return spring 713, when the degreasing agent is sprayed and the temporary storage frame 53 moves downward, the return spring 713 will release its elastic force, thereby driving the sliding bar 710 and the plug 711 to return to their original positions.

[0034] like Figures 1 to 3 As shown, a dividing strip 25 is provided at the upper end of the lifting platform 23 .

[0035] Specifically, by providing the dividing strip 25 , when the lifting platform 23 moves upward, the dividing strip 25 will separate the aluminum bars 8 on the surface of the conveyor belt 11 , thereby ensuring that there is only one aluminum bar 8 inside the lifting platform 23 .

[0036] like Figure 4 As shown, an air blowing gun 709 is provided at one end of the extrusion platform 61 close to the pushing frame 51 .

[0037] Specifically, by setting up the air blow gun 709, when the aluminum rod 8 moves to the inside of the extrusion table 61 for extrusion, the air blow gun 709 is started, and the air blow gun 709 will blow away the debris generated by the extrusion, thereby preventing the debris from entering the inside of the extrusion die 63 with the aluminum rod 8 and affecting the extrusion effect.

[0038] like Fig. 9 As shown, a filter screen 715 is provided inside the transfer pipe 704 , and the filter screen 715 is provided at the upper end of the plug 711 .

[0039] Specifically, by providing the filter 715 , the degreasing agent can be filtered, thereby preventing impurities in the degreasing agent from being smeared onto the surface of the aluminum rod 8 .

[0040] like Fig. 9As shown, a pressure strip 717 is provided at the upper end of the plug 711 , and the pressure strip 717 is in contact with the filter screen 715 .

[0041] Specifically, by setting the pressure strip 717, when the plug 711 moves upward, the plug 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 avoid the blockage of the filter screen 715, but also will not affect the transfer of the degreasing agent.

[0042] Working principle: When in use, first place the aluminum rod on the surface of the conveyor belt, then start the conveyor belt, the conveyor belt will drive the aluminum rod to move to the inside of the lifting platform and contact with the conveyor roller, then start the lifting platform to move upward, the lifting platform will drive the aluminum rod to move flush with the abutment plate, then start the sliding block, the sliding block will drive the abutment plate to move together, and the abutment plate will transfer the aluminum rod to the inside of the heating furnace, then start the heating furnace to heat the aluminum rod. Through heating, the crystal structure of aluminum changes, thereby reducing the hardness and strength of the aluminum rod and improving its plasticity, which makes it easier for the aluminum rod to be shaped into the desired shape during the extrusion process, then start the temporary storage frame to move upward, the temporary storage frame will move upward flush with the aluminum rod, then transfer the aluminum rod to the inside of the temporary storage frame, and then the temporary storage frame is placed on the upper surface of the conveyor belt. Move upward for a distance, at this time, the upper surface of the temporary storage frame will contact with the abutment block, and drive the abutment block to move upward for a distance, and the abutment block will drive the plug to move together through the sliding bar, thereby opening the channel between the nozzle and the transfer pipe, and because the length of the sliding bar is too long, when the abutment block drives the sliding bar to move upward, the sealing of the side wall of the transfer pipe can always be guaranteed, and then the degreaser will pass out from the nozzle and spray onto the surface of the aluminum rod. After the spraying is completed, start the temporary storage frame to move downward again. When the temporary storage frame drives the aluminum rod to move flush with the sliding rod, start the sliding rod, the sliding rod will move toward the direction of the aluminum rod and push the aluminum rod to the inside of the conveying trough, as the sliding rod presses one end of the aluminum rod, the desired shape can be formed through the extrusion die, thereby completing the extrusion of the aluminum profile.

[0043] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
