Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment equipment, in particular to a heating device for forgings. Background Art

[0002] The heating devices for forgings mainly include electric heating furnaces and flame heating furnaces. During the forging process, the heating of metal billets is a crucial link. The correct heating method can not only improve the plasticity of metals, reduce the deformation resistance, but also significantly enhance the surface quality and dimensional accuracy of forgings, while reducing energy consumption and increasing productivity.

[0003] The heating of forgings is achieved by the heat generated by resistance or induced current. In an electric heating furnace, the metal billet is placed in a conductive environment. When current passes through, due to the effect of resistance, heat is generated inside the metal, thus achieving heating. In existing forging heating devices, special heating devices are usually customized according to the diameter of the billet, so that the diameter of a single billet is adapted in the heating device, resulting in that the device can only heat one side of a single billet, which is not conducive to improving work efficiency. If the heating device is to be used to heat multiple billets with smaller diameters, the billets will contact the inner part of the heating device, which may cause the problem of uneven heating of the billets. Therefore, the utility model proposes a heating device for forgings. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and provide a heating device for forgings.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A heating device for forgings, comprising a heating furnace, a support assembly, and a fixing assembly. The support assembly is arranged on the heating furnace, the fixing assembly is arranged on one side of the heating furnace close to the support assembly, and a transmission assembly is arranged on one side of the heating furnace close to the support assembly;

[0006] The support assembly includes a placement rack and a first rotating shaft. The first rotating shaft is arranged on both sides of the heating furnace. Driving wheels are fixedly connected to both ends of the first rotating shaft close to the heating furnace. A driven wheel is arranged on one side of the heating furnace close to the driving wheel. A transmission belt is connected between the driving wheel and the driven wheel in a transmission manner. A support rod is fixedly connected to the driven wheel. The placement rack is fixedly connected to one side of the support rod far from the driven wheel. A first motor is fixedly connected to the top of the heating furnace. The first rotating shaft close to the first motor is fixedly connected to the output end of the first motor.

[0007] As a preferred embodiment, the transmission assembly includes a second rotating shaft and a support block. The support block is fixedly connected to one side of the driving wheel on the heating furnace. The second rotating shaft is rotatably connected to the support block. One end of the second rotating shaft close to the driving wheel is fixedly connected with a driven gear. One end of the driving wheel close to the driven gear is fixedly connected with a crown gear. The driven gear meshes with the crown gear.

[0008] The technical effect of adopting the above further solution is that: there are first rotating shafts arranged on both sides of the heating furnace, but the output end of the first motor is only connected to one of the first rotating shafts. Therefore, a transmission structure needs to be installed between the two first rotating shafts. When the driving wheel rotates, the crown gear rotates together with the driving wheel. Furthermore, the crown gear on one side drives the crown gear on the other side to rotate through the driven gear and the second rotating shaft, and then the driving wheels on both sides rotate together.

[0009] As a preferred embodiment, the fixing assembly includes a top plate and a clamp. The top plate is arranged on one side of the heating furnace close to the placing rack. Fixed blocks are fixedly connected to both sides of the top plate. A second motor is fixedly connected to the fixed block. The output end of the second motor is fixedly connected with a bidirectional lead screw. The clamp is threadedly connected to one end of the bidirectional lead screw close to the fixed block.

[0010] The technical effect of adopting the above further solution is that: start the second motor, and the second motor drives the clamp to move through the bidirectional lead screw. Since the clamps are arranged at both ends of the bidirectional lead screw, and there are two threads with opposite directions on the bidirectional lead screw, the clamps move towards the middle direction of the top plate at the same time, so that the clamps can clamp the blank on the placing rack to prevent it from slipping.

[0011] As a preferred embodiment, a unidirectional lead screw is rotatably connected to one side of the top plate close to the heating furnace. The unidirectional lead screw is threadedly connected to the heating furnace and the driven wheel.

[0012] The technical effect of adopting the above further solution is that: when the thread of the unidirectional lead screw is on the driven wheel, when the driven wheel drives the unidirectional lead screw to move downward along the thread, the unidirectional lead screw barrel pushes the top plate to place the clamp on the top of the placing rack.

[0013] As a preferred embodiment, a telescopic rod is fixedly connected between the top plate and the heating furnace. The length of the telescopic rod is greater than the length of the unidirectional lead screw.

[0014] The technical effect of adopting the above further solution is that: fix the telescopic rod on the top plate to limit the top plate, avoiding the top plate rotating with the unidirectional lead screw, and thus maintaining the stability of the clamp.

[0015] As a preferred embodiment, a slider is fixedly connected to one side of the fixture close to the top plate. A chute is formed on one side of the top plate close to the slider. The fixture is slidably connected to the top plate through the slider and the chute. A bottom plate is slidably connected to one side of the fixture close to the placement rack.

[0016] The technical effect of adopting the above further solution is as follows: A slider is installed on the fixture, enabling the fixture to move along the chute, thereby enhancing the stability of the fixture during movement. A bottom plate that can follow the contraction of the fixture is installed on the fixture. When the fixture moves on the surface of the placement rack, the bottom plate will be placed on the top of the blank, thus preventing the blank from being squeezed into a piled-up state when the fixture contracts.

[0017] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0018] 1. By providing a support assembly, starting the first motor, the first motor drives the driving wheel, the transmission belt, and the driven wheel to rotate through the first rotating shaft, causing the placement rack to rotate to the horizontal direction along with the driven wheel. Thus, the blank inside the heating furnace is supported at the center of the heating furnace by the placement rack, preventing the blank from contacting the inner wall of the heating furnace during heating. While solving the problem of uneven heating of the blank, it also enables the heating device to heat multiple blanks simultaneously, improving the heating efficiency of the device.

[0019] 2. By providing a fixing assembly, starting the second motor, the second motor drives the fixture to move through the bidirectional lead screw. Since the fixture is arranged at both ends of the bidirectional lead screw and two threads with opposite directions are provided on the bidirectional lead screw, the fixture simultaneously moves towards the middle direction of the top plate, enabling the fixture to clamp the blank on the placement rack and prevent it from slipping, improving the stability of the heating device during operation.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] As Figures 1-4 shown, this embodiment provides a technical solution: A heating device for forgings, including a heating furnace 1, a support component 2, and a fixing component 3. The support component 2 is arranged on the heating furnace 1, the fixing component 3 is arranged on one side of the heating furnace 1 close to the support component 2, and a transmission component 4 is arranged on one side of the heating furnace 1 close to the support component 2;

[0032] As Figures 1-2As shown in the figure, the support assembly 2 includes a placement rack 21 and a first rotating shaft 23. The first rotating shaft 23 is arranged on both sides of the heating furnace 1. Driving wheels 24 are fixedly connected to both ends of the first rotating shaft 23 close to the heating furnace 1. A driven wheel 26 is arranged on one side of the heating furnace 1 close to the driving wheels 24. A transmission belt 25 is connected between the driving wheels 24 and the driven wheel 26. A support rod 27 is fixedly connected to the driven wheel 26. The placement rack 21 is fixedly connected to the side of the support rod 27 away from the driven wheel 26. A first motor 22 is fixedly connected to the top of the heating furnace 1. The first rotating shaft 23 close to the first motor 22 is fixedly connected to the output end of the first motor 22. By placing a plurality of billets with smaller diameters inside the heating furnace 1 and starting the first motor 22, the first motor 22 drives the driving wheels 24 to rotate through the first rotating shaft 23, so that the driving wheels 24 drive the driven wheel 26 to rotate through the transmission belt 25, and the placement rack 21 rotates along with the support rod 27 through the support rod 27, so that the placement rack 21 rotates to the horizontal, and then the placement rack 21 supports the billets inside the heating furnace 1 at the center inside the heating furnace 1, avoiding the contact between the billets during heating and the inner wall of the heating furnace 1. While solving the problem of uneven heating of the billets, it can also enable the heating device to heat a plurality of billets at the same time, improving the heating efficiency of the device.

[0033] Furthermore, as Figure 2 shown in the figure, the transmission assembly 4 includes a second rotating shaft 41 and a support block 43. The support block 43 is fixedly connected to one side of the driving wheel 24 on the heating furnace 1. The second rotating shaft 41 is rotatably connected to the support block 43. A driven gear 42 is fixedly connected to one end of the second rotating shaft 41 close to the driving wheel 24. A crown gear 44 is fixedly connected to one end of the driving wheel 24 close to the driven gear 42. The driven gear 42 meshes with the crown gear 44. Since the first rotating shafts 23 are arranged on both sides of the heating furnace 1, but the output end of the first motor 22 is only connected to one of the first rotating shafts 23, therefore, a transmission structure needs to be installed between the two first rotating shafts 23. When the driving wheel 24 rotates, the crown gear 44 rotates together with the driving wheel 24. Then, the crown gear 44 on one side drives the crown gear 44 on the other side to rotate through the driven gear 42 and the second rotating shaft 41, and then the driving wheels 24 on both sides rotate together.

[0034] In the above solution, there is also a problem that the billets slide off from both sides of the placement rack 21. As Figure 3As shown in the figure, the fixing component 3 includes a top plate 31 and a fixture 32. The top plate 31 is arranged on one side of the heating furnace 1 close to the placing rack 21. Fixed blocks 6 are fixedly connected to both sides of the top plate 31. A second motor 35 is fixedly connected to the fixed block 6. The output end of the second motor 35 is fixedly connected to a bidirectional lead screw 34. The fixture 32 is threadedly connected to one end of the bidirectional lead screw 34 close to the fixed block 6. By starting the second motor 35, the second motor 35 drives the fixture 32 to move through the bidirectional lead screw 34. Since the fixture 32 is arranged at both ends of the bidirectional lead screw 34 and two threads with opposite directions are arranged on the bidirectional lead screw 34, the fixture 32 moves towards the middle direction of the top plate 31 at the same time, so that the fixture 32 can clamp the blank on the placing rack 21 to prevent it from slipping.

[0035] One side of the top plate 31 close to the heating furnace 1 is rotatably connected with a unidirectional lead screw 33. The unidirectional lead screw 33 is threadedly connected to the heating furnace 1 and the driven wheel 26. By threading the unidirectional lead screw 33 on the driven wheel 26, when the driven wheel 26 drives the unidirectional lead screw 33 to move downward along the thread, the unidirectional lead screw 33 then pushes the top plate 31 to place the fixture 32 on the top of the placing rack 21.

[0036] In the above solution, there is also a problem that the top plate 31 rotates together with the unidirectional lead screw 33. A telescopic rod 5 is fixedly connected between the top plate 31 and the heating furnace 1. The length of the telescopic rod 5 is greater than the length of the unidirectional lead screw 33. By fixing the telescopic rod 5 to the top plate 31, the telescopic rod 5 limits the top plate 31 to prevent the top plate 31 from rotating together with the unidirectional lead screw 33, thereby maintaining the stability of the fixture 32.

[0037] A slider 37 is fixedly connected to one side of the fixture 32 close to the top plate 31, as Figure 4 shown. A chute 38 is opened on one side of the top plate 31 close to the slider 37. The fixture 32 is slidably connected to the top plate 31 through the slider 37 and the chute 38. A bottom plate 36 is slidably connected to one side of the fixture 32 close to the placing rack 21. By installing the slider 37 on the fixture 32, the fixture 32 can move along the chute 38, thereby improving the stability of the fixture 32 during movement. The bottom plate 36 that can follow the contraction of the fixture 32 is installed on the fixture 32. When the fixture 32 moves on the surface of the placing rack 21, the bottom plate 36 will be placed on the top of the blank, thereby preventing the blank from being squeezed into a piled-up state when the fixture 32 contracts.

[0038] Working principle: As Figures 1-4 shown:

[0039] During use: First, start motor 1 22. Motor 1 22 drives the rotation of the driving wheel 24 through the rotating shaft 1 23, causing the driving wheel 24 to drive the rotation of the driven wheel 26 through the transmission belt 25. The driven wheel 26 drives the rotation of the placement rack 21 through the support rod 27, making the placement rack 21 horizontally placed on both sides of the heating furnace 1. When the placement rack 21 rotates, the unidirectional lead screw 33 rotates together with the driven wheel 26, thereby causing the unidirectional lead screw 33 to push the top plate 31 to move to the top of the placement rack 21, placing the fixture 32 on the surface of the placement rack 21. Then, place the blank on the placement rack 21. Since the bottom plate 36 is slidably connected to the fixture 32 and the bottom plate 36 covers the top of the blank, start motor 2 35. Motor 2 35 drives the fixture 32 to move along the thread on the bidirectional lead screw 34 through the bidirectional lead screw 34, causing the fixture 32 to contract towards the blank, thereby fixing the blank and preventing the blank from falling off the placement rack 21.

[0040] Finally, start the heating furnace 1. The heating furnace 1 is achieved by the heat generated by resistance or induced current. In the heating furnace 1, the metal blank is placed in a conductive environment. When current passes through, due to the effect of resistance, heat is generated inside the metal, thus achieving heating.

[0041] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
