Description

Technical Field

[0001] The present invention relates to the technical field of aluminum alloy preparation, and more specifically, to a device for improving the yield of aluminum alloy extrusion materials. Background Art

[0002] Aluminum alloy extrusion is an alloy material with aluminum as the main component. Aluminum rods are melted and extruded to obtain aluminum materials with different cross-sectional shapes. However, the proportion of added alloys is different, and the mechanical properties and application fields of the produced industrial aluminum profiles are also different. The production of aluminum alloy extrusion products can be completed through the device for producing aluminum alloy extrusion products.

[0003] However, the existing devices for producing finished aluminum alloy extrusion products have the following shortcomings: during the extrusion process, the aluminum alloy is shaped by the die, and the die itself is not heated evenly, resulting in the aluminum alloy not being effectively extruded and formed during the process of passing through the die. In addition, the die is fixed inside the device and is difficult to replace, which reduces the diversification effect of the extrusion molding. At the same time, if the length of the aluminum alloy extrusion is long after extrusion molding, it is easy to cause the aluminum alloy extrusion to deform, thereby reducing the quality of the finished product.

DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] Example 1:

[0025] As attached Figure 1 To the attached Figure 5 As shown:

[0026] The present invention discloses a device for improving the yield rate of aluminum alloy extruded materials. The device comprises an operating platform 1, a forming box 2, an extruder 3, and a shaping box 4. The forming box 2 is fixedly mounted on the upper end of the operating platform 1, and the extruder 3 and the shaping box 4 are provided at the left and right ends of the operating platform 1. A power supply box 21 is provided on the top of the forming box 2, and a fixing frame 22 is provided at the middle end of the forming box 2. A power line 211 is connected to the lower end of the power supply box 21, and is electrically connected to a heater 212 at the upper end of the fixing frame 22 via the power line 211. A forming die 25 is further provided inside the fixing frame 22, and a compression port 24 and a lifting frame 23 are provided at the front end of the forming die 25. Balls 231 are embedded in the curved surface of the lifting frame 23 to assist in the stable movement of the alloy aluminum rod.

[0027] The molding die 25 is composed of a molding groove 251, a heating block 252, a heat-conducting ring 253, a heat-conducting block 254 and a positioning hole 255. The molding groove 251 is embedded in the middle of the molding die 25. The heating block 252 is embedded in the molding die 25 and the upper end thereof abuts against the heater 212. The lower end of the heating block 252 is connected to the heat-conducting ring 253, and the upper and lower ends of the heat-conducting ring 253 are both provided with heat-conducting blocks 254. The two heat-conducting blocks 254 are located above and below the molding groove 251. The positioning hole 255 is provided with a heat-conducting ring 253. 55 is embedded in the edge of the forming mold 25, and a knob 221 is also provided on the outside of the forming box 2, and a threaded rod 222 is connected to the inside of the knob 221. The threaded rod 222 passes through the inside of the fixing frame 22 and is threadedly connected. A rotating ball 223 is fixed to the inner end of the threaded rod 222, and the rotating ball 223 is installed in the middle of the outer side of the clamping plate 224 outside the forming mold 25 with a clearance fit. A positioning pin 225 is also provided on the inside of the clamping plate 224, and the positioning pin 225 is inserted into the inner end of the fixing frame 22. It is installed inside the positioning hole 255, and an extrusion push rod 31 is provided in the middle of the extruder 3, and the extrusion push rod 31 and the lifting frame 23 are at the same height of the horizontal axis. The extrusion push rod 31 is pushed laterally by the cylinder built into the extruder 3 to push the alloy aluminum rod placed on the lifting frame 23 toward the forming mold 25. In the present invention, the heated alloy aluminum rod is placed on the lifting frame 23, and the extrusion push rod 31 is driven to move laterally by starting the extruder 3 to push the alloy aluminum rod toward the direction of the forming mold 25. The compression port 24 facilitates the alloy aluminum rod to enter the forming groove 251 of the forming mold 25, and in the process of extrusion molding, the heater 212 is heated by the power box 21. At this time, the upper and lower heating blocks 252 are used to conduct heat to the forming groove 251 through the heat conducting ring 253, so that the heating of the forming groove 251 is more uniform, ensuring that the alloy aluminum rod can be effectively extruded through the inside of the forming groove 251 to form an aluminum alloy extruded material.

[0028] In a preferred technical solution, the forming mold 25 is a cylindrical structure, and the heat-conducting ring 253 is located at the same center inside the forming mold 25. The heat-conducting ring 253 can make the two heat-conducting blocks 254 conduct heat synchronously and evenly, so that the forming groove 251 is heated more evenly, ensuring that the alloy aluminum rod can be effectively extruded through the forming groove 251.

[0029] A preferred technical solution is that there are two of the knob 221, threaded rod 222, rotating ball 223 and clamping plate 224, and the two clamping plates 224 are both arc-shaped structures, clamped at the two ends of the outer side of the forming mold 25, and installed inside the positioning hole 255 through the positioning pin 225 to improve the clamping stability of the clamping plate 224 on the forming mold 25. The rotating ball 223 is driven to rotate by the rotation of the threaded rod 222 to adjust the clamping plate 224, so that the clamping plate 224 can quickly clamp and release the forming mold 25, which is convenient for replacing the forming mold 25 inside the fixed frame 22. By replacing different forming molds 25, the extrusion molding of aluminum alloy extrusions can be diversified.

[0030] Example 2: Based on Example 1, Figure 6 To the attached Figure 7 As shown:

[0031] A support plate 41 is provided just below the shaping box 4, and the support plate 41 is fixed to the upper surface of the left end of the operating table 1. An air outlet 411 is embedded on the surface of the support plate 41, and the edge of the support plate 41 is connected to the cooling box 45 provided inside the shaping box 4 through an air duct 412. A box body 42 is also provided on the top of the shaping box 4, and a cylinder 43 is installed inside the box body 42. An extrusion rod 431 is provided at the output end of the cylinder 43, and a spring pipe sleeve 432 and a buffer pressure rod 433 are connected to the lower end of the extrusion rod 431. The spring makes the extrusion rod 431 and the buffer pressure rod 433 elastically buffered, driving the shaper 44 at the lower end of the buffer pressure rod 433 to elastically extrude the aluminum alloy extruded material at the upper end of the support plate 41. The shaper 44 is composed of a connecting plate 441, a hinged plate 442, a pressing wheel 443, a cooling hole 444 and a connecting hose 445. The connecting plate 441 is fixed to the lower end of the buffer pressure rod 433 in the middle, and hinged plates 442 are provided on both sides of the connecting plate 441. The lower end of the hinged plate 442 is connected to the axis of the pressing wheel 443. The pressing wheel 4 The surface of the pressing wheel 43 is embedded with cooling holes 444, and the interior of the pressing wheel 443 is connected to the cooling box 45 through a connecting hose 445. In the present invention, as the aluminum alloy rod is continuously extruded in the forming groove 251, the aluminum alloy extrusion material moves to the support plate 41. At this time, the cooling air is transmitted to the inside of the support plate 41 through the cooling box 45. At this time, the air outlet 411 discharges the cooling air to act on the lower surface of the extruded aluminum alloy extrusion material, cooling and shaping the aluminum alloy extrusion material, accelerating the shaping effect of the aluminum alloy extrusion material, and avoiding the extrusion after the extrusion. The aluminum alloy extrusion material is deformed due to excessive temperature, and the extrusion rod 431 is driven down by the cylinder 43 at the upper end. Under the elastic buffering of the spring tube sleeve 432 and the buffer pressure rod 433, the pressing wheel 443 elastically extrude the upper surface of the aluminum alloy extrusion material, effectively avoiding the deformation caused by the long length of the aluminum alloy extrusion material, improving the yield of the aluminum alloy extrusion material, and spraying the cooling air generated by the cooling box 45 onto the upper surface of the low aluminum alloy extrusion material through the cooling holes 444 on the surface of the pressing wheel 443, accelerating the shaping effect of the aluminum alloy extrusion material.

[0032] A preferred technical solution is that the upper end surface and both side surfaces of the support plate 41 are provided with air outlets 411, and cooling air is transmitted to the interior of the support plate 41 through the cooling box 45. At this time, the air outlets 411 discharge the cooling air to act on the lower surface of the extruded aluminum alloy extrusion, cooling and shaping the aluminum alloy extrusion, accelerating the shaping effect of the aluminum alloy extrusion, and preventing the aluminum alloy extrusion from being deformed due to excessive temperature after extrusion.

[0033] A preferred technical solution is that the connecting plate 441 and the hinged plate 442 are installed at a vertical angle so that the pressing wheel 443 is parallel to the connecting plate 441. Under the buffering of the buffer pressure rod 433, the pressing wheel 443 flattens the upper end surface of the aluminum alloy extrusion with a longer length, thereby avoiding deformation of the aluminum alloy extrusion, thereby reducing the quality of the finished product of the aluminum alloy extrusion and improving the yield of the aluminum alloy extrusion. In addition, the cooling air generated by the cooling box 45 is sprayed onto the upper surface of the low aluminum alloy extrusion through the cooling holes 444 on the surface of the pressing wheel 443, thereby accelerating the shaping effect of the aluminum alloy extrusion.

[0034] Utilizing the technical solution of the present invention, or those skilled in the art designing similar technical solutions inspired by the technical solution of the present invention to achieve the above technical effects, all fall within the scope of protection of the present invention.
