Description

Technical Field

[0001] This utility model relates to the field of forging heating furnace technology, specifically a heating device for a metal forging furnace with uniform heating rate. Background Technology

[0002] Forging is a processing method that uses forging machinery to apply pressure to a metal billet, causing it to undergo plastic deformation to obtain forgings with certain mechanical properties, shapes, and dimensions. It is one of the two major components of forging. A forging furnace is required during the forging process to heat the workpiece.

[0003] For example, application number CN202321421968.2 discloses a uniformly heated metal forging furnace heating device, including a forging furnace body. Support frames are installed at both ends of the furnace body, and a servo motor a is installed on one side of the top of each support frame. The servo motor a is connected to a gear. The support frame is connected to a lifting platform, and a servo motor b is installed at the top of the lifting platform. The bottom of the servo motor b is connected to a transmission wheel, and each transmission wheel is connected to a transmission belt. A connecting arm is installed at the bottom of each transmission wheel and is connected to a holding tank. Heating devices are installed on both sides inside the forging furnace body. This uniformly heated metal forging furnace heating device, by allowing the workpiece placed in the holding tank to rotate, enables it to receive uniform heating, thereby avoiding uneven heating and cracking of the workpiece, and improving the yield and efficiency of forging.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problem of uneven heating of metal workpieces during heating, where the workpieces are generally statically fixed in the heating furnace and their positions are not easily changed, leading to cracks and damage to the workpieces, affecting subsequent forging operations and reducing overall work efficiency, there are still some issues. During use, when the heated forgings are removed from the heating furnace for replacement with new parts, the high-temperature container needs to be removed using specialized tools. As a result, the furnace opening remains open for an extended period, causing a large amount of high-temperature leakage and cooling. This prolongs the heating time of the new parts, severely reducing production efficiency. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a uniformly heated metal forging furnace heating device with the advantage of auxiliary heat preservation. This solves the problem that when heated forgings are taken out of the heating furnace for replacement with new parts, the high-temperature container needs to be removed with special tools, resulting in the furnace opening being open for a long time, causing a large amount of high temperature leakage and cooling, which in turn prolongs the heating time of the new parts and seriously reduces production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a uniformly heated metal forging furnace heating device, comprising a heating furnace, a rectangular frame, lugs, a screw, a motor, a hanging can cover, and a holding can. The bottom inner side of the rectangular frame is fixedly connected to the top of both sides of the heating furnace. The surface of the lugs is slidably connected to the inner wall of the rectangular frame. The surface of the screw is threadedly connected to the inner wall of the lugs. Both sides of the screw are movably connected to both sides of the inner wall of the rectangular block via shaft pins. The bottom of the motor is fixedly connected to the top of the rectangular frame. The output end of the motor extends through to the top of the inner wall of the rectangular frame. The output end of the motor is fixedly connected to the top of the screw. Both sides of the hanging can cover are fixedly connected to the inner side of the lugs. The holding can is hung to the bottom of the hanging can cover. Both sides of the top of the heating furnace are slidably connected to heat-insulating covers, which are in contact with the inner sides of the heat-insulating covers. Support components are fixedly connected to the inner sides of both sides of the heat-insulating covers. Driving mechanisms are fixedly connected to the bottom of both sides of the heating furnace.

[0007] In a preferred embodiment of this invention, the support assembly includes a slider, the inner side of which is fixedly connected to the inner sides of both sides of the heat insulation cover, and a support rod is sleeved inside the slider, the inner side of which is fixedly connected to the bottom of both sides of the rectangular frame.

[0008] In a preferred embodiment of this utility model, the driving mechanism includes an electric telescopic rod, the inner side of which is fixedly connected to the bottom of both sides of the heating furnace, a short plate is fixedly connected to the output end of the electric telescopic rod, and a rotating rod is movably connected to both sides of the short plate via a pivot pin. The bottom of the inner side of the rotating rod is movably connected to both sides of the heat preservation cover via a pivot pin.

[0009] As a preferred embodiment of this utility model, a fixing plate is fixedly connected to the outer side of the support rod, and a reset assist tension spring is sleeved on the surface of the support rod. The two ends of the reset assist tension spring are fixedly connected to the fixing plate and the inner side of the rectangular frame.

[0010] As a preferred embodiment of this utility model, an L-shaped mounting plate is provided on the right side of the hanging can cover. The back of the L-shaped mounting plate is fixedly connected to the top of the front of the rectangular frame. A trigger switch is fixedly connected to the left side of the bottom of the L-shaped mounting plate. A controller is provided at the bottom of the L-shaped mounting plate. The back of the controller is fixedly connected to the front of the rectangular frame. The trigger switch and the motor are both electrically connected to the controller through wires. The controller is electrically connected to the electric telescopic rod through wires.

[0011] As a preferred embodiment of this invention, a rubber pad is provided at the bottom of the trigger switch, and the bottom of the rubber pad is fixedly connected to the right side of the top of the hanging can lid.

[0012] As a preferred embodiment of this invention, a linear bearing is fixedly connected to the inner wall of the slider, and the inner wall of the linear bearing is slidably connected to the surface of the support rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up heat-insulating covers, allows the holding tank to be pulled out of the furnace by the lifting of the can lid. The drive mechanism is then activated, causing the two heat-insulating covers to close under the limiting and support of the support components, thus shutting down the heating furnace again. This solves the problem that when heated forgings are removed from the heating furnace for replacement with new parts, the high-temperature holding tank needs to be removed with specialized tools, resulting in the furnace opening remaining open for a long time, causing a large amount of high-temperature leakage and cooling. This, in turn, prolongs the heating time of the new parts, severely reducing production efficiency. This invention achieves an auxiliary heat-insulating effect.

[0015] 2. By setting up a support component, when the heat preservation cover moves, the slider fixedly connected to it slides on the support rod. The support rod plays a supporting and limiting role, restricting the slider to move only along its axial direction, ensuring that the heat preservation cover opens and closes accurately and maintaining the sealing state of the heating furnace.

[0016] 3. This utility model, by setting a driving mechanism, allows the user to activate the electric telescopic rod when the heating furnace is opened so that the two insulation covers can be moved symmetrically outward. This causes the output end of the electric telescopic rod to push the short plate to move. When the short plate moves, the rotating rod rotates through the pivot pin. The rotation of the rotating rod then pushes the insulation cover to rotate around the pivot pin, causing the rotating rod to rotate from an inclined state to a horizontal state, thus pushing the insulation cover symmetrically outward. When the electric telescopic rod pulls the short plate down, the insulation cover moves symmetrically inward accordingly, thereby improving the user's ease of operation. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4 As shown, this utility model provides a uniformly heated metal forging furnace heating device, including a heating furnace 1, a rectangular frame 2, lugs 3, a screw 4, a motor 5, a hanging can cover 6, and a holding can 7. The bottom inner side of the rectangular frame 2 is fixedly connected to the top of both sides of the heating furnace 1. The surface of the lugs 3 is slidably connected to the inner wall of the rectangular frame 2. The surface of the screw 4 is threadedly connected to the inner wall of the lugs 3. Both sides of the screw 4 are movably connected to both sides of the inner wall of the rectangular frame 1 through shaft pins. The bottom of the motor 5 is fixedly connected to the top of the rectangular frame 2. The output end of the motor 5 extends through to the top of the inner wall of the rectangular frame 2. The output end of the motor 5 is fixedly connected to the top of the screw 4. Both sides of the hanging can cover 6 are fixedly connected to the inner side of the lugs 3. The holding can 7 is hung to the bottom of the hanging can cover 6. Both sides of the top of the heating furnace 1 are slidably connected to heat preservation covers 8, which are in contact with the inner side of the heat preservation covers 8. Support components 9 are fixedly connected to the inner side of both sides of the heat preservation covers 8. Both sides of the bottom of the heating furnace 1 are fixedly connected to drive mechanisms 10.

[0024] refer to Figure 2 The support component 9 includes a slider 91, the inner side of which is fixedly connected to the inner sides of both sides of the heat preservation cover 8. A support rod 92 is sleeved inside the slider 91, and the inner side of the support rod 92 is fixedly connected to the bottom of both sides of the rectangular frame 2.

[0025] As a technical optimization of this utility model, by setting a support component 9, when the heat insulation cover 8 moves, the slider 91 fixedly connected to it slides on the support rod 92. The support rod 92 plays a supporting and limiting role, restricting the slider 91 to move only along its axial direction, ensuring that the heat insulation cover 8 opens and closes accurately, and maintaining the sealing state of the heating furnace 1.

[0026] refer to Figure 1 and Figure 2 The drive mechanism 10 includes an electric telescopic rod 101. The inner side of the electric telescopic rod 101 is fixedly connected to the bottom of both sides of the heating furnace 1. The output end of the electric telescopic rod 101 is fixedly connected to a short plate 102. Both sides of the short plate 102 are movably connected to a rotating rod 103 through a pivot pin. The bottom of the inner side of the rotating rod 103 is movably connected to both sides of the heat preservation cover 8 through a pivot pin.

[0027] As a technical optimization of this utility model, by setting a drive mechanism 10, when the user needs the two insulation covers 8 to move outward symmetrically and open the heating furnace 1, the electric telescopic rod 101 is activated, so that its output end pushes the short plate 102 to move. When the short plate 102 moves, the rotating rod 103 is rotated through the shaft pin. The rotation of the rotating rod 103 pushes the insulation cover 8 to rotate around the shaft pin, so that the rotating rod 103 rotates from an inclined state to a horizontal state, pushing the insulation cover 8 outward symmetrically. Then, when the electric telescopic rod 101 pulls the short plate 102 down, the insulation cover 8 moves inward symmetrically accordingly, thereby improving the user's ease of operation.

[0028] refer to Figure 2 A fixing plate 11 is fixedly connected to the outside of the support rod 92, and a reset assist spring 12 is sleeved on the surface of the support rod 92. The two ends of the reset assist spring 12 are fixedly connected to the fixing plate 11 and the inside of the rectangular frame 2.

[0029] As a technical optimization of this utility model, by setting a fixing plate 11 and a reset assist spring 12, when the heat insulation cover 8 is closed, the reset assist spring 12 is stretched and stores elastic potential energy. Then, when the heat insulation cover 8 is opened, the spring releases elastic potential energy and applies a pulling force to the heat insulation cover 8 in the opening direction, so that the short plate 102 is pushed upward, causing the rotating plate to rotate and the heat insulation cover 8 to be pushed outward symmetrically, which is more smooth.

[0030] refer to Figure 1 An L-shaped mounting plate 13 is provided on the right side of the hanging can cover 6. The back of the L-shaped mounting plate 13 is fixedly connected to the top of the front of the rectangular frame 2. A trigger switch 14 is fixedly connected to the left side of the bottom of the L-shaped mounting plate 13. A controller 15 is provided at the bottom of the L-shaped mounting plate 13. The back of the controller 15 is fixedly connected to the front of the rectangular frame 2. The trigger switch 14 and the motor 5 are both electrically connected to the controller 15 through wires. The controller 15 is electrically connected to the electric telescopic rod 101 through wires.

[0031] As a technical optimization of this utility model, by setting up an L-shaped mounting plate 13, a contact switch and a controller 15, when the top right side of the hanging can cover 6 contacts the trigger switch 14 during the upward process of the can cover 6 with the ear block 3, the trigger switch 14 receives the signal and controls the motor 5 to stop running, so that the hanging can cover 6 stops rising. Then, the electric telescopic rod 101 receives the start signal, so that the heating furnace 1 can be closed and kept stable.

[0032] refer to Figure 1 A rubber pad 16 is provided at the bottom of the trigger switch 14, and the bottom of the rubber pad 16 is fixedly connected to the right side of the top of the hanging can lid 6.

[0033] As a technical optimization of this utility model, by setting a rubber pad 16, when the can lid 6 rises and contacts the trigger switch 14, the rubber pad 16 first contacts the trigger switch 14, and buffers the impact force through its own elastic deformation, reducing damage to the trigger switch 14 and ensuring that the trigger switch 14 can work normally.

[0034] refer to Figure 3 A linear bearing 17 is fixedly connected to the inner wall of the slider 91, and the inner wall of the linear bearing 17 is slidably connected to the surface of the support rod 92.

[0035] As a technical optimization of this utility model, by setting a linear bearing 17, during the sliding process of the slider 91 along the support rod 92, the inner wall of the linear bearing 17 contacts the surface of the support rod 92, and rolling friction replaces sliding friction, which greatly reduces the friction force, allowing the slider 91 to move more easily on the support rod 92 and ensuring the stable operation of the heat preservation cover 8.

[0036] The working principle and usage process of this utility model are as follows: When the user needs to heat the part to be forged, first hang the container 7 on the can cover 6, then place the workpiece into the container 7. Then, start the motor 5 to drive the screw 4 to rotate, causing the lug 3 to lower the can cover 6 until it closes with the heating furnace 1. Then, start the heating furnace 1 to heat the workpiece in the container 7. After the temperature reaches the required point, start the motor 5 to drive the screw 4 in the reverse direction to rotate, causing the can cover 6 to return to its original position and rise until the container 7 is pulled out of the heating furnace 1. Then, the rubber pad 16 on top of the can cover 6 touches the trigger switch 14. After receiving the signal, the trigger switch 14 controls the motor 5 to stop running. The movement of the can cover 6 is stopped, and then the electric telescopic rod 101 receives a start signal. The output end of the electric telescopic rod 101 pulls the short plate 102 downward. When the short plate 102 moves, it causes the rotating rod 103 to rotate through the shaft pin. The rotation of the rotating rod 103 pushes the heat preservation cover 8 to rotate around the shaft pin, so that the rotating rod 103 changes from an inclined state to a vertical state. Thus, the two heat preservation covers 8 move inward symmetrically through the support and limit provided by the slider 91 and the support rod 92, and finally come into contact, completing the sealing of the furnace opening of the heating furnace 1. Therefore, it prevents the heating furnace 1 from being open for a long time when the furnace opening is changed to hold the can 7, which would cause excessive leakage of high temperature inside and cause it to cool down, thus increasing the heating time of the new workpiece and reducing production efficiency. Thus, it has the advantage of auxiliary heat preservation.

[0037] In summary, this uniformly heated metal forging furnace heating device, by setting up heat-insulating covers 8, allows the drive mechanism 10 to be activated after the holding tank 7 is pulled out of the furnace by the lifting of the hanging tank cover 6. This causes the two heat-insulating covers 8 to close under the limiting and support of the support component 9, thus closing the heating furnace 1 again. This solves the problem that when heated forgings are taken out of the heating furnace for replacement with new parts, the high-temperature holding tank needs to be removed with special tools, resulting in the furnace opening being in a long-term open state, causing a large amount of high-temperature leakage and cooling, which in turn prolongs the heating time of the new parts and seriously reduces production efficiency.
