Technical Field

[0002] Aluminum alloy profile extruder is a key equipment used to extrude aluminum alloy billets through dies. It is widely used in construction, transportation, electronics, aerospace and other fields. Its working principle is to push the aluminum alloy billet heated to a plastic state into the mold cavity through hydraulic or mechanical drive, so that it can be formed through the mold opening under high pressure, and finally obtain the profile with the desired cross-sectional shape. The extruder is mainly composed of an extrusion barrel, an extrusion rod, a die, a heating system and a control system. Among them, the extrusion barrel and the extrusion rod are made of high-strength heat-resistant alloy materials to withstand the high temperature and high pressure working environment; the die is customized according to the cross-sectional shape of the profile, which directly affects the molding accuracy and surface quality. Modern extruders are usually equipped with advanced temperature control, pressure regulation and automated operating systems to ensure production efficiency and product quality.

[0003] Existing aluminum alloy profile extruders need to clean the remaining material inside the mold after each molding.

By setting the cylinder 73, it can rub against the inside of the forming mechanism 9, so that when the support tube 72 moves horizontally and enters the inside of the forming mechanism 9, the horizontal movement of the support tube 72 is more stable. The inner cavity of the circular tube 74 is slidably connected with a sliding tube 75. One end of the sliding tube 75 located in the inner cavity of the circular tube 74 is fixedly connected with a first spring 76. The end of the first spring 76 is fixedly connected to the inner wall of the support tube 72. The outer surface of the sliding tube 75 is fixedly connected with a rack 77, which is made of rubber material. The number of the racks 77 is several, and the racks 77 are evenly distributed. The racks 77 are pressed and adapted with the annular grooves provided on the inner wall of the circular tube 74. By providing the circular tube 74 and providing several annular grooves therein, the racks 77 can be made to vibrate inside the circular tube 74 when moving laterally inside the circular tube 74, thereby causing the sliding tube 75 to vibrate. By providing the first spring 76, the vibration of the sliding tube 75 can be increased, thereby causing the oxide on the outer surface of the aluminum material to be shaken off, and when the sliding tube 75 moves to the inside of the circular tube 74, the sliding tube 75 can be made to vibrate.

The end of the breathable cylinder 91 is fixedly connected to a feed pipe 93, and a slot 94 is provided on the upper surface of the feed pipe 93. The extrusion head 78 is frictionally matched with the inner wall of the feed pipe 93, and the outer side surface of the breathable cylinder 91 is fixedly connected to a feed box 92. By providing the breathable cylinder 91, when the aluminum material is extruded and deformed to generate high-temperature heat, the heat on the outer surface of the aluminum material can be discharged through the holes on the outer surface of the breathable cylinder 91. By providing the feed pipe 93 and the slot 94, the aluminum material can be guided so that the aluminum material can stably enter the inner cavity of the breathable cylinder 91.

By setting the straight rod 96, the rotating tube 97 can be limited, so that the rotating tube 97 can rotate on the outer surface of the straight rod 96, and then the blocking frame 98 can rotate in the inner cavity of the feed box 92. By setting the blocking frame 98, the aluminum material placed in the inner cavity of the feed box 92 can be blocked, and the aluminum material can be moved when it is needed. When extrusion is performed, the blocking frame 98 no longer blocks the aluminum column, so that the aluminum column can enter the inner cavity of the air-permeable cylinder 91. By setting the first retaining ring 99, the second retaining ring 910 and the retaining rod 911, the blocking frame 98 can be prevented from rotating when the retaining rod 911 is inserted into the inner cavity of the first retaining ring 99 and the second retaining ring 910.

The outer surface of the extrusion column 957 is fixedly connected with a second spring 958, and the end of the second spring 958 is fixedly connected to the inner wall of the limiting frame 955. By setting the limiting frame 955, the tooth plate 956 can be limited, so that the tooth plate 956 can produce a lateral movement effect. By setting the extrusion column 957, when the extrusion sleeve 710 moves laterally with the extrusion head 78, the extrusion sleeve 710 can squeeze the extrusion column 957, thereby causing the tooth plate 956 to produce a lateral movement. By setting the second spring 958,After the tooth plate 956 and the extrusion column 957 move, elastic potential energy can be stored, and then the tooth plate 956 and the extrusion column 957 can be restored to their original positions. The upper surface of the first mold 952 is fixedly connected to a track frame 959, and the first mold 952. A partition frame 9510 is fixedly connected to the inner wall of the track frame 959, a guide block 9513 is fixedly connected to the side of the partition frame 9510 close to the fixed cylinder 951, a fixed column 9511 is fixedly connected to the side of the partition frame 9510 away from the guide block 9513, a spacer block 9512 is fixedly connected to the end of the fixed column 9511, the outer surface of the first mold 952 is movably connected to the second mold 953, the upper surface of the second mold 953 is fixedly connected to a connecting frame 9514, the end of the connecting frame 9514 is fixedly connected to a sliding column 9515, the sliding column 9515 is slidably connected to the inner cavity of the track frame 959, and the two ends of the sliding column 9515 are symmetrically fixedly connected to gears 9516, Meshing with the tooth plate 956, by setting the partition frame 9510 and the guide block 9513, the extruded aluminum column can be divided into four strips, and then under the guidance of the subsequent partition block 9512 and the second mold 953, the four aluminum columns are re-fused into a tube. By setting the sliding column 9515, it can move in the inner cavity of the track frame 959, so that the first mold 952 and the second mold 953 can produce the effect of opening and closing and horizontal movement, so as to facilitate the cleaning of the residual material inside after the aluminum tube is formed. By setting the gear 9516, when the tooth plate 956 moves horizontally, the gear 9516 can be rotated, so that the second mold 953 can be opened and closed with the first mold 952.

[0048] Working principle: When in use, the operator places the aluminum column in the heater for heating. When the temperature of the aluminum column reaches 500 degrees Celsius, the aluminum column is placed in the inner cavity of the feed box 92, and then the positioning rod 911 is pulled so that the blocking frame 98 no longer blocks the aluminum column. Then the stepper motor 65 is connected to the power supply and the switch is turned on, so that the rotating rod 66 drives the screw rod 67 to rotate. During the rotation of the screw rod 67, the sliding ring 69 moves laterally on the outer surface of the screw rod 67, thereby driving the movable frame 611 and the fixed frame 71 to move laterally; when the fixed frame 71 moves laterally, the extrusion head 78 is squeezed with the end of the aluminum column, and under the action of pressure, the sliding tube 75 and the rack 77 move in the inner cavity of the circular tube 74. During the process, the rack 77 contacts the annular groove on the inner wall of the circular tube 74 and generates vibration. The vibration is transmitted to the aluminum column through the extrusion head 78, and the outer surface of the aluminum column is heated. The oxides generated by the heat are shaken off, increasing the strength of the aluminum after forming; as the extrusion head 78 continues to extrude the aluminum column, the aluminum column contacts the partition frame 9510, and the extruded aluminum column can be divided into four strips, and then under the guidance of the subsequent spacer block 9512 and the second mold 953, the four aluminum columns are re-fused into a tube; when all the aluminum columns are extruded, the extrusion sleeve 710 on the outer surface of the extrusion head 78 will contact the extrusion column 957. During the contact process, the extrusion column 957 drives the tooth plate 956 to move laterally. During the process, the sliding column 9515 moves laterally in the inner cavity of the track frame 959, thereby separating the first mold 952 from the second mold 953, and then the tooth plate 956 drives the gear 9516 to rotate, thereby expanding the second mold 953, so that the residual material inside can be easily removed, which is convenient for the next forming work.
