Description

Technical Field

[0001] The invention relates to the field of forging equipment for forging metal bars, in particular to an automatic turntable type forging gas furnace. Background Art

[0002] Forging is a processing method that uses a forging machine to apply pressure to a metal blank to cause it to undergo plastic deformation in order to obtain a forging with certain mechanical properties, shape, and size. Forging can eliminate defects such as loose cast metal produced during the smelting process and optimize the microstructure. At the same time, because the complete metal flow lines are preserved, the mechanical properties of forgings are generally better than those of castings of the same material. Therefore, in related machinery, important parts with high loads and severe working conditions are mostly forged, except for simpler shapes that can be made of rolled plates, profiles, or welded parts. Existing forging furnaces usually have two conveying methods, the first is chain type, and the second is track type. Both chain type and track type conveying methods perform heat treatment during the conveying process. Both devices have the following disadvantages: 1. Large area; 2. When heat treating the last batch of bars, transportation needs to be stopped, and workers have to manually take out the bars after the heat treatment, which is very troublesome; 3. The top and bottom of the bar are heated unevenly, affecting the forging quality. Summary of the invention

The conveying frame 51 is connected to the main driving device 4 through a swing structure 57; The swing structure 57 includes a positioning shaft 571, a swing push frame 572, a swing push block 573, a limiting slide rail 574, a push slider 575, a positioning push wheel 576, a swing push wheel 577 and a swing limiting plate 578; The positioning shaft 571 is installed on the support frame a; The bottom of the conveying frame 51 is rotatably mounted on the positioning shaft 571; The swing push frame 572 is connected to the main driving rod 41; The swing push block 573 is installed at the end of the swing push frame 572; The limiting slide rail 574 is installed on the support frame a, and the slide groove of the limiting slide rail 574 is arranged in a horizontal direction; The pushing slider 575 is slidably installed in the limiting slide rail 574; The positioning push wheel 576 is rotatably mounted on the active end of the push slider 575; The swing push block 573 is connected to the positioning push wheel 576; The swing push wheel 577 is rotatably mounted on the driven end of the push slider 575; The swing limit plate 578 is installed on the conveying frame 51; The swing push wheel 577 moves on the same horizontal line with the supporting point of the swing limit plate 578, and the swing limit plate 578 moves with the movement of the swing push wheel 577, so that the conveying frame 51 can swing up and down in the vertical direction, and the inclination angle of the conveying frame 51 relative to the positioning shaft 571 can be adjusted, so that the pushing mechanism 6 can dock with or detach from the forged metal bar lifting groove 56; The swing push wheel 577 is connected to the swing limit plate 578. When the swing push wheel 577 moves forward and backward, under the gravity of the feeding mechanism 5 itself, the swing limit plate 578 moves forward and backward with respect to the supporting point of the swing push wheel 577, so that the feeding mechanism 5 swings up and down relative to the positioning shaft 571 to attach the feeding mechanism 5.

When the first driving block 82 rotates counterclockwise, the material transfer push rod 84 is driven to disengage from the gear teeth of the driving gear 85, and the driving gear 85 is stationary at this time; The material transfer push rod 84 is mounted on the support frame a through a reset block, and the reset block allows the material transfer push rod 84 to always remain in a straight line when sliding; When the main driving rod 41 retracts, the common push rod 81 is reset, driving the second driving block 83 to reset, the second driving block 83 cancels the thrust on the first driving block 82, the bottom end of the first driving block 82 is reset, the material transfer push rod 84 loses the pulling force applied by the first driving block 82, the first driving block 82 pushes the material transfer push rod 84 to move rightward and disengage from the driving gear 85, the material transfer push rod 84 is reset, and the material transfer push rod 84 loses the pulling force on the driving gear 85, and at the same time the positioning mechanism 7 positions the driving shaft 86, so that the driving shaft, the driving gear, and the material transfer tray are fixed; During the extension of the rear half of the total driving rod 41, the positioning pin 74 is first driven to disengage from the positioning gear 73, and then the second driving block 83 pushes the bottom end of the first driving block 82 to move in the same direction, so that the second driving block 83 pushes the first driving block 82 to move in the same direction, and finally the first driving block 82 drives the material transfer push rod 84 to move in the same direction, and the material transfer push rod 84 drives the driving gear 85 to rotate a set angle; Furthermore, the material transfer push rod 84 includes a connecting rod 841 and a push head 842, wherein the connecting rod 841 is connected to the first driving block 82, and the push head 842 is integrally formed at the end of the connecting rod 841; The push head 842 is an inverted push head, which can hook the gear teeth of the driving gear 85 to rotate; Furthermore, the rotating material tray 87 includes a support body 871 and a partition plate 872. The support body 871 is circular. A plurality of partition plates 872 are provided. The plurality of partition plates 872 are welded to the outer peripheral side of the support body 871 at even intervals. A plurality of forging chambers 873 are formed between the plurality of partition plates 872 and the receiving material tray 88. The plurality of forging chambers 873 are arranged in a circumference. The forging chamber 873 is docked with the pushing mechanism 6 or the receiving tray 88. The pushing mechanism 6 pushes the forged metal bar into the forging chamber. When the forging chamber is aligned with the discharge port, the bar automatically falls from the discharge port to the discharge mechanism 9 under its own gravity. A relatively small gap is left between the partition 872 and the receiving tray 88 at the bottom. When the partition 872 rotates, it pushes the forged metal bar b in the forging chamber 873 to roll forward, so that the side of the forged metal bar b can be heated in all directions and heated more evenly. During operation, the forged metal bar b is sent to the forging chamber 873. When the pushing mechanism 6 pushes the forged metal bar b, the positioning mechanism 7 positions the driving gear 85, and then positions the driving shaft 86, and then positions the rotating disc 87 to ensure that the rotating disc 87 does not move. After the pushing is completed, the positioning mechanism 7 is separated from the rotating mechanism 8, and the push rod 84 on the rotating mechanism 8 drives the driving gear 85 to rotate forward by one gear tooth, and the rotating disc 87 rotates forward by the angle of a forging chamber 873, and then repeats the above action. After a forging chamber 873 rotates one circle, the forging chamber 873 docks with the discharge port 881 on the receiving disc 88, and the heat-treated forged metal bar b falls into the discharge channel 91 through the discharge port 881 and is transported out. After one forging chamber rotates one circle (from the process of the pusher mechanism pushing the bar into the forging chamber to the discharge of the bar from the discharge port), the heat treatment of the forged metal bar is completed; Since the rotating material plate 87 is set to be circular, the floor space of the equipment is effectively reduced, and the forged metal bar b is continuously heat-treated during the rotating transportation process, the heating time is fixed, the heat treatment effect is better, and the quality of each forged metal bar b after heat treatment is effectively guaranteed; Furthermore, the receiving plate 88 is provided with a material discharge port 881, the forging chamber 873 is connected to the material discharge port 881, and the material discharge port 881 is connected to the material discharge channel 91; The length and width of the discharge port 881 of the forging chamber are both greater than or equal to the length and width of the forging chamber 873, so as to ensure that the forged metal bar material can be discharged smoothly; During operation, the receiving plate 88 remains stationary, and the rotating plate 87 moves forward the width of a forging chamber 873 at a time. When the forging chamber 873 moves to the discharge port 881, the bottom of the forged metal bar b is supported by the receiving plate 88. When the forging chamber 873 moves to be aligned with the discharge port 881, the forged metal bar b automatically falls into the discharge channel 91 under its own gravity, completing the discharge after forging.

[0023] In a specific embodiment of the present invention, see Figure 1-Figure 10 The pushing mechanism 6 includes a pushing frame 61, a pushing rod 62 and a pushing channel 63; The pusher frame 61 is connected to the main driving rod 41; The push rod 62 is installed on the push frame 61; The pushing channel 62 is horizontally installed in the furnace body 2 and penetrates the furnace body 2. The feeding end of the pushing channel 62 is connected to the pushing rod 61, and the discharging end of the pushing channel 62 is connected to the forging chamber on the rotating disk 87. The straight line where the lowest end of the inner bottom of the pushing channel 63 is located and the straight line where the lowest end of the pushing rod 62 is located are located on the same horizontal line; The pushing mechanism 6 is responsible for pushing the forged metal bar b on the loading mechanism 5 into the transfer mechanism 8. When the total driving rod 41 retracts, it drives the pushing frame 61 to move in the same direction (the direction is the pushing direction), and then drives the pushing rod 62 to move toward the pushing channel 63. In the process of the pushing rod 62 moving toward the pushing channel 63, the pushing rod 62 pushes the forged metal bar in the forged metal bar accommodating groove into the pushing channel 63, and finally pushes the forged metal bar b into the forging chamber 873. At this time, the transfer plate 87 does not move (that is, the positioning mechanism positions the positioning gear, and the driving gear and the driving shaft are not moving); When the main driving rod is extended, it drives the pushing frame 61 to reset, and at the same time drives the pushing rod 62 to reset, ensuring that the pushing rod 62 will not affect the feeding of the feeding mechanism 5.

[0024] In a specific embodiment of the present invention, see Figure 1-Figure 10 , the positioning mechanism 7 includes the common push rod 81, the second driving block 83, the push rod 71, the driving lever 72, the positioning gear 73, the positioning pin 74 and the positioning plate 75; The push rod 71 is installed below the second driving block 83; The support frame a is provided with a lever support block (this structure is not important and is not marked in the figure), and the driving lever 72 is rotatably mounted on the lever support block; The active end of the driving lever 72 is clamped on the push rod 71; The positioning plate 75 is installed on the support frame a; The positioning plate 75 is provided with a limiting hole, and the positioning pin 74 is slidably installed in the limiting hole; The active end of the positioning pin 74 is connected to the driven end of the driving lever 72; a small spring is installed at the active end of the positioning pin 74 to limit the connection position between the positioning pin 74 and the driving lever 72 to ensure the stability of the movement of the positioning pin 74; a limiting hole is provided at the driven end of the driving lever 72, the diameter of the limiting hole is smaller than the diameter of the stopper provided at the end of the positioning pin 74 to prevent the positioning pin 74 from being separated from the driving lever 72, and the diameter of the limiting hole is larger than the diameter of the active end of the positioning pin 74 to ensure that the movement of the driving lever 72 and the positioning pin 74 is not restricted; The positioning pin 74 is provided with a return spring 76, which is mounted on the positioning plate 75; when the return spring 76 is compressed, the positioning pin 74 is disengaged from the positioning gear 73; when the return spring 76 is automatically extended, the positioning pin 74 is inserted into the positioning gear 73 to position the positioning gear 73, and then the driving gear 85, the driving shaft 86 and the rotating material tray 87 are positioned; The positioning gear 73 is mounted on the driving shaft 86. The positioning gear 73 is located below the driving gear 85. The positioning gear 73 rotates synchronously with the driving shaft 86 and the driving gear 85 or is stationary synchronously. The positioning pin 74 is inserted into or out of the tooth gap of the positioning gear 73, and the positioning gear 73 is positioned when inserted, and the positioning is cancelled when disengaged; When the front half of the total driving rod 41 is extended, the common push rod 81 is driven to move in the same direction. At this time, the bottom end of the second driving block 83 moves in the opposite direction, driving the push rod 71 to swing in the opposite direction, thereby driving the driving lever 72 to swing, so that the driving lever 72 pulls the positioning pin 74 away from the gear gap of the positioning gear 73 to cancel the positioning. When the total driving rod 41 retracts, it drives the common push rod 81 to move in the same direction. At this time, the second driving block 83 cancels the driving force applied to the driving lever 72. The driving lever 72 is reset under the action of the rebound force of the reset spring 76 of the positioning pin 74, so that the positioning pin 74 loses the pulling force, so that the positioning pin 74 extends forward under the action of the reset spring 76 and is inserted into the gear tooth gap of the positioning gear 73.

[0025] In a specific embodiment of the present invention, see Figure 1-Figure 10 The total driving device 4 is a telescopic cylinder, and the total driving rod 41 is the pneumatic rod of the telescopic cylinder.

[0026] In a specific embodiment of the present invention, see Figure 1-Figure 10 , The flame spraying device 3 comprises four flame spraying nozzles 31, which are evenly installed on the top wall of the furnace body and extend into the furnace body; The circumference of the circle where the center of the flame nozzle 31 is located is located directly above the circumference where the top center point of the partition is located; The flame nozzle 31 sprays flame toward the forging chamber 873; The height of the flame nozzle from the forging chamber can be adjusted according to actual conditions.

[0027] In a specific embodiment of the present invention, see Figure 1-Figure 10 ,See Figure 2 The discharging mechanism 9 includes a discharging channel 91 and a chain-type discharging portion 92, and the discharging channel 91 is obliquely arranged on the supporting frame a; one end of the discharging channel 91 is connected to the transfer mechanism 8, and the chain-type discharging portion 92 is connected to the other end of the discharging channel 91.

[0028] Working process: The push rod feeding part 12 of the feeding mechanism 1 pushes the forged metal bar b on the belt feeding part 11 to the loading mechanism 5, one bar at a time, and accurately delivers the forged metal bar b to the forged metal bar lifting groove 56 of the loading mechanism 5; when the first forged metal bar in the forged metal bar lifting groove 56 is transported to align with the pushing groove 63 of the pushing mechanism 6, the main driving device 4 starts to work, the main driving rod contracts, and pushes the forged metal bar into the pushing groove 63 until it is sent into the forging chamber 873 ; During the contraction of the total driving rod 41, the common push rod 81 is driven to move in the same direction, thereby driving the transfer push rod 84 to disengage from the driving gear, and at the same time, the positioning pin 74 is disengaged from the tension, and under the action of its own reset spring, it is inserted into the gear gap of the positioning gear to position the positioning gear, ensuring that the transfer plate 87 does not rotate when the pushing mechanism 6 pushes the material; when the forged metal bar b is transported to the top of the discharge port 881, the forged metal bar b automatically falls into the discharge channel 91 and is transported out through the chain-type discharge part 92; When a forged metal bar b is pushed onto the transfer tray 87, the main drive device 4 drives the main drive rod 41 to extend outward. At this time, the common push rod 81 moves in the same direction, driving the upper part of the second drive block 83 to move in the same direction, and then the second drive block 83 uses the top force to drive the lower part of the first drive block 82 to move in the same direction. The first drive block 82 pulls the transfer push rod 84 in the same direction. At this time, the undercut push head 842 on the transfer push rod 84 is stuck in the gear tooth gap of the driving gear 85, and continues to pull the driving gear 85 forward one grid; at the same time, the transfer tray rotates forward one grid; at the same time, the second drive block 83 drives the driving lever 72 to rotate, and when the driving lever 72 rotates, it pulls the positioning pin 74 to move, so that the positioning pin 74 disengages from the gear tooth gap of the positioning gear 73, thereby canceling the positioning of the positioning gear 73.

[0029] Advantages: The swing structure 57, the pushing mechanism 6, the transferring mechanism 8 and the positioning mechanism 7 in the feeding mechanism of the present application are all driven by the same total driving device and are linked by connecting rods, levers and other mechanisms, so that all actions are implemented in an orderly manner, ensuring that all actions are completed at the controlled time point, effectively eliminating the action deviation caused by the time error caused by not using the same driving device, greatly improving the working accuracy, ensuring that the equipment can work without error for a long time, and ensuring the normal and orderly progress of the forging work; the entire process of pushing, unloading and heat treatment is cyclical, and some actions are performed simultaneously, which effectively saves the entire heat treatment time and greatly improves the processing efficiency; and because the transferring mechanism works in a cyclical manner, it can discharge the last heat-treated forged metal bar out of the furnace body, and the entire process does not require manual operation by workers, which effectively reduces labor and protects the safety of workers while improving efficiency.
