The profile head is in a high-temperature softening state just after leaving the die, and is prone to bending and twisting due to its own weight or uneven force. Manual assistance is required to pull the profile head to move it in the correct direction to avoid deflection.

DETAILED DESCRIPTION
[0022] Next, combine Figures 1-6 A specific embodiment of the present invention is described in detail.
[0023] refer to Figures 1-6 An extrusion device for forging aluminum alloys includes a frame 1, on which a hot forging zone, a forming zone and a receiving zone for the aluminum alloy are provided. The hot forging zone includes an extruder 11 installed on the frame 1, the forming zone includes a forming machine 10 installed on the frame 1, and the receiving zone includes a conveyor 12 connected to the frame 1. The conveyor 12 is provided with a receiving assembly for forging aluminum alloys. After the aluminum alloy is hot forged at high temperature by the extruder 11, it is molded by the forming machine 10 and then received by the conveyor 12.
[0024] refer to Figure 5The conveyor 12 is provided with a receiving component that is easy to receive, including a sliding block 13 that slides on the conveyor 12. The sliding blocks 13 are symmetrically distributed on both sides of the conveyor 12. The two sliding blocks 13 are fixed with a straight rod 131 through the support ears 14. The straight rod 131 is connected with a blocking plate 16. A torsion spring 15 is compressed between the blocking plate 16 and the support ear 14. The torsion spring 15 assists the blocking plate 16 to complete the flipping action.
[0025] In particular, the sliding block 13 and the blocking plate 16 are both made of lightweight and high-temperature resistant materials. The aluminum alloy molded in the molding machine 10 contacts and pushes the blocking plate 16, causing the blocking plate 16 and the sliding block 13 to move, thereby achieving the effect of directional extension of the aluminum alloy on the conveyor 12.
[0026] The forged aluminum alloy is extruded from the forming machine 10, contacts and pushes the baffle plate 16, and the baffle plate 16 moves, and the sliding block 13 moves in a controlled manner until it stops at the tail end of the conveyor 12. The purpose is to achieve the effect of directional extension of the forged aluminum alloy on the conveyor 12 through the extrusion force of the forged aluminum alloy on the baffle plate 16, avoid the burning hazards of manual assisted traction, and at the same time avoid the problem of irregular extension of the forged aluminum alloy after extrusion due to internal stress deformation due to different cooling rates of various parts.
[0027] refer to Figure 3 A collection frame (not shown in the figure) is provided at the tail end of the conveyor 12, the purpose of which is to collect the forged aluminum alloy and transfer it to the next process. In order to facilitate the forged aluminum alloy to fall directly into the collection frame from the tail end of the conveyor 12, the blocking plate 16 should be avoided (that is, the blocking plate 16 is flipped and flattened), so the following settings are made: an extrusion member 113 is fixedly connected to the conveyor 12, and a roller 115 is rotatably connected to the extrusion member 113. A blocking member 119 is slidably connected to the sliding block 13, and the blocking member 119 is squeezed and matched with the end of the blocking plate 16, that is: in the initial state, the blocking plate 16 maintains a static upright state under the extrusion action of the blocking member 119.
[0028] refer to Figure 5 The blocking member 119 is fixed with a wedge block 118, which can be squeezed and matched with the extrusion member 113. The purpose is to realize the up and down sliding movement of the blocking member 119 by the extrusion of the wedge block 118 and the extrusion member 113, and the downward movement of the blocking member 119 to cancel the extrusion with the blocking plate 16, thereby realizing the avoidance effect of the blocking plate 16 being flipped and flattened. A pressure spring 114 is compressed between the blocking member 119 and the sliding block 13.
[0029] Initially, the blocking plate 16 and the blocking member 119 are squeezed, the torsion spring 15 accumulates force, the blocking plate 16 stands upright and stationary, the forged aluminum alloy is extruded from the forming machine 10, contacts and pushes the blocking plate 16, the blocking plate 16 moves, the blocking member 119, the wedge block 118, and the sliding block 13 are controlled to move to the tail end of the conveyor 12, the wedge block 118 contacts and squeezes the extrusion member 113 and the roller 115, the wedge block 118 moves downward, the blocking member 119 is controlled to move downward, the pressure spring 114 is deformed, and the blocking member 119 moves downward and gradually disengages from the extrusion of the blocking plate 16. Under the action of the torsion spring 15, the blocking plate 16 flips and flattens, thereby achieving the avoidance effect of the blocking plate 16, so that the continuously produced forged aluminum alloy can smoothly fall from the tail end of the conveyor 12 into the collection frame.
[0030] During the above process, since the wedge block 118 and the extrusion piece 113 maintain an extrusion state, the blocking piece 119 and the blocking plate 16 cancel the extrusion. Under the action of the torsion spring 15, the blocking plate 16 maintains a flipped and flattened state at the tail end of the conveyor 12. To facilitate the continuous use of the device, after the forged aluminum alloy is collected, the blocking plate 16 should be reset to its initial state. Therefore, the device uses a pull rope assembly to cooperate to complete the reset action of the blocking plate 16.
[0031] refer to Figure 3 The pull rope assembly includes a reel 117 installed on the conveyor 12. It is worth noting that the reel 117 is installed on the side away from the extruder 11, that is, the tail end of the conveyor 12. The purpose is to prevent the braking resistor, relay and other electronic components inside the reel 117 from being affected by the high temperature inside the extruder 11, and to ensure the normal operation of the electronic components inside the reel 117.
[0032] refer to Figure 2 The reel 117 is connected to the first sliding member 116 through a pull rope, and the sliding block 13 is fixed with a second sliding member 1161. The second sliding member 1161 and the first sliding member 116 are both slidably connected to the conveyor 12. The second sliding member 1161 and the first sliding member 116 are connected by a steel rope 17, and the steel rope 17 is fixed in length, that is: this pull rope assembly realizes the reset of the blocking plate 16 through the relative movement of the first sliding member 116 and the second sliding member 1161. The specific steps are as follows: Initially, the second sliding member 1161 and the first sliding member 116 are respectively distributed at the head end and the tail end of the conveyor 12 (that is: the side of the conveyor 12 close to the extruder 11 and the side away from the extruder 11).
[0033] The conveyor 12 is provided with multiple fixing parts 18, and roller pulleys are installed on the fixing parts 18. The steel rope 17 passes through the roller pulleys on the fixing parts 18 to connect the second sliding part 1161 and the first sliding part 116, aiming to avoid the steel rope 17 from directly contacting the conveyor 12. The friction loss of the steel rope 17 is reduced through the roller pulleys, and at the same time it is beneficial to the pulling action of the steel rope 17.
[0034] The forged aluminum alloy pushes the blocking plate 16 to move, and the sliding block 13 and the second sliding member 1161 are controlled to move in the same direction. Based on the existence of the steel rope 17, the first sliding member 116 and the second sliding member 1161 move toward each other, that is, the first sliding member 116 and the second sliding member 1161 move to the tail end and the head end of the conveyor 12 respectively, and the pull rope in the reel 117 extends with the movement of the first sliding member 116. Subsequently, the wedge block 118 is squeezed with the extrusion member 113, and the blocking plate 16 is moved on the conveyor. The tail end of the machine 12 is maintained in a flipped state. After all the continuously produced forged aluminum alloys fall into the collection frame, the winder 117 is started to move the first sliding member 116 toward the tail end of the conveyor 12 by pulling the rope. Under the action of the steel rope 17, the second sliding member 1161 moves toward the head end of the conveyor 12, that is, the second sliding member 1161 and the first sliding member 116 are redistributed at the head and tail ends of the conveyor 12, and the sliding block 13 and the blocking plate 16 are controlled to move, that is, close to one side of the extruder 11.
[0035] After the second sliding member 1161 is reset, the wedge block 118 is disengaged from the extrusion member 113, and the blocking member 119 and the wedge block 118 move up and reset under the action of the pressure spring 114. At this time, the end of the blocking plate 16 has passed the blocking member 119, and under the action of the torsion spring 15, the blocking plate 16 still maintains the flipped and flattened state. In order to facilitate the continuous use of the blocking plate 16, the blocking plate 16 should be restored to the upright state. The following technical solution is specifically adopted: a fixed rod 112 is fixedly connected to one side of the blocking plate 16, and a first gear 110 is connected to the sliding block 13. The first gear 110 is keyed to a rotating rod 111. The rotating rod 111 is squeezed and matched with the fixed rod 112, aiming to squeeze the fixed rod 112 through the rotation action of the rotating rod 111, thereby realizing the reset action of the blocking plate 16 to flip and stand upright.
[0036] In order to realize the rotation of the rotating rod 111 , a first rack 19 is provided on the side of the conveyor 12 close to the extruder 11 . The rotation of the rotating rod 111 depends on the cooperation between the first rack 19 and the first gear 110 .
[0037] In the above, as the sliding block 13 moves toward the tail end of the conveyor 12, the first gear 110 moves and meshes with the first rack 19, the first gear 110 rotates, and the rotating rod 111 rotates downward to flatten, that is, the rotating rod 111 rotates downward to cancel the squeezing of the fixed rod 112, the purpose is: not to affect the flipping and flattening action of the blocking plate 16, as the winder 117 is started, the sliding block 13 moves toward the direction of the extruder 11, the first gear 110 moves synchronously, and the rotating rod 111 remains flattened until the first gear 110 approaches and meshes with the first rack 19, the first gear 110 rotates in the opposite direction, driving the rotating rod 111 to rotate in the opposite direction and reset, and the rotating rod 111 contacts and squeezes the fixed rod 112 after reversing, thereby driving the fixed rod 112 to flip and reset in the opposite direction, thereby the blocking plate 16 flips and resets in the opposite direction.
[0038] The stopper 119 is then released, and the stopper 119 and the wedge block 118 are reset upwards, that is, the stopper 119 is re-limited at the front end of the stopper 16, thereby completing the complete reset action of the stopper 16, and the stopper 16 is maintained in an upright state under the limiting action of the stopper 119, which is convenient for subsequent recycling.
[0039] When the aluminum alloy contacts and pushes the blocking plate 16, the aluminum alloy (temperature of about 450-550°C) just extruded from the extruder 11 is still in a semi-solid state. The aluminum alloy contacts and pushes the blocking plate 16, which easily causes the head to sag or twist. Therefore, the device uses a clamping assembly to clamp the aluminum alloy head to provide an axial pulling force, while keeping the aluminum alloy centered and moving in a straight line.
[0040] refer to Figure 5The clamping assembly includes a telescopic rod 23 connected to the blocking plate 16, the telescopic end of the telescopic rod 23 is fixedly connected to an extrusion plate 2, and a force storage spring 22 wound on the telescopic rod 23 is compressed between the extrusion plate 2 and the blocking plate 16, and a screw 25 is connected to the blocking plate 16 through a protrusion. The two ends of the screw 25 are threadedly connected to one end of the center plate 26 at the threaded ends, that is, one end of the two center plates 26 passes through the extrusion plate 2 and the blocking plate 16 and is threaded on the screw 25, and the middle section of the screw 25 is fixedly connected to the second gear 24 at the unthreaded rod. The second rack 21 is fixed on the extrusion plate 2, and the second rack 21 passes through the blocking plate 16 and meshes with the second gear 24, aiming to make the two center plates 26 approach each other through the meshing of the second rack 21 and the second gear 24, thereby achieving the effect of clamping the aluminum alloy.
[0041] The aluminum alloy extruded from the extruder 11 first contacts the extrusion plate 2, extruding and pushing the extrusion plate 2 to move backward, the telescopic end of the telescopic rod 23 contracts, the force storage spring 22 deforms, and as the extrusion plate 2 moves backward, the second rack 21 is controlled to move backward and engage the second gear 24, the second gear 24 rotates, the screw 25 is controlled to rotate, and the two center plates 26 are controlled to move toward each other, that is, the two center plates 26 approach each other, thereby achieving the effect of the two center plates 26 clamping the head of the aluminum alloy, and at the same time limiting the aluminum alloy, that is, the aluminum alloy is centered on the extrusion plate 2, so that the extrusion force of the aluminum alloy on the extrusion plate 2 is concentrated, and as the aluminum alloy is continuously extruded, the extrusion force of the aluminum alloy on the extrusion plate 2 increases, the telescopic end of the telescopic rod 23 is in a fully contracted state, and the extrusion force of the aluminum alloy on the extrusion plate 2 will be transmitted to the blocking plate 16, thereby pushing the blocking plate 16 and the extrusion plate 2 to move synchronously.
[0042] When the blocking plate 16 and the extrusion plate 2 move synchronously, it is difficult to ensure that the moving speed of the blocking plate 16 and the extrusion plate 2 is the same, so that the moving speed of the blocking plate 16 may be greater than that of the extrusion plate 2, which in turn causes the second gear 24 to engage with the second rack 21 to cause the second gear 24 to reverse, thereby controlling the screw 25 to reverse and controlling the two center plates 26 to move in opposite directions, thereby canceling the clamping action on the aluminum alloy.
[0043] refer to Figure 4In order to achieve the clamping action of the two centering plates 26 on the aluminum alloy, this device is implemented through a limit assembly. The limit assembly includes a positioning buckle 3 fixed to the sliding block 13, and a pin 31 is slidably connected to the positioning buckle 3. An inclined wedge 32 is fixed to the pin 31, and the inclined wedge 32 is provided with an inclined surface. A tension spring 33 is compressed between the inclined wedge 32 and the positioning buckle 3. A sink groove is opened on the conveyor 12, and the inclined wedge 32 cooperates with the sink groove to achieve the positioning effect of the pin 31. As the aluminum alloy squeezes the extrusion plate 2, the extrusion plate 2 moves backward and then the end of the extrusion plate 2 squeezes the pin 31. The pin 31 is forced to move downward, the wedge 32 moves downward, and the tension spring 33 is deformed. When the end of the extrusion plate 2 moves backward and passes the pin 31, the extrusion plate 2 and the pin 31 are released from extrusion. Under the action of the tension spring 33, the wedge 32 and the pin 31 move upward and reset. At this time, the extrusion plate 2 is positioned due to the blocking effect of the pin 31, so that the two center plates 26 maintain a clamping state on the aluminum alloy. In particular: during the above-mentioned backward movement of the extrusion plate 2, the blocking plate 16 does not move. The specific reasons are as follows.
[0044] Only when the telescopic end of the telescopic rod 23 is in a fully retracted state, the extrusion force of the aluminum alloy on the extruded plate 2 can be transmitted to the blocking plate 16, causing the blocking plate 16 to move backward. Due to the presence of the support ear 14 and the rotating rod 111, the sliding block 13 moves backward. However, the inclined wedge 32 cooperates with the sink groove to stabilize the latch 31 on the positioning buckle 3, that is, the latch 31, the inclined wedge 32 and the sink groove together constitute a blocking structure, which plays a role in preventing the sliding block 13 from moving backward. Therefore, during the process of the aluminum alloy causing the extruded plate 2 to move backward, the blocking plate 16 remains stationary for a certain period of time. When the telescopic end of the telescopic rod 23 is in a fully retracted state, it means that the end of the extruded plate 2 has passed the latch 31. Under the limit of the latch 31, the two center plates 26 maintain a clamping state on the aluminum alloy. As the extrusion force of the aluminum alloy on the extruded plate 2 gradually increases, the blocking plate 16 and the sliding block 13 are forced through the positioning buckle 3. The wedge 32 is then moved upwards by the cooperation of the inclined surface and the recess on the wedge 32, and the wedge 32 is moved upwards, the wedge 32 is moved upwards under control, the tension spring 33 is deformed, and then the wedge 32 and the recess are disengaged and slide along with the sliding block 13 on the conveyor 12. That is, at this time, the wedge 32 and the recess limit the extrusion plate 2, and the extrusion plate 2 remains stationary relative to the blocking plate 16, thereby achieving the two centering plates 26 to maintain a clamping state on the aluminum alloy. At this time, the forged aluminum alloy exerts equal force on the extrusion plate 2 and the blocking plate 16. Therefore, the aluminum alloy moves the extrusion plate 2 and the blocking plate 16 synchronously toward the tail end of the conveyor 12. Under the action of the two centering plates 26, the aluminum alloy is centered and directionally extended on the conveyor 12 through mechanical linkage, further solving the safety hazards existing in the manual assistance process, while improving the practicality and efficiency of the device.

Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
