Description
Technical Field
[0001] This invention belongs to the field of automatic feeding technology for forging furnaces, specifically relating to an automatic feeding and centering device for a forging heating machine used for complex structural parts. Background Technology
[0002] A forging heating machine is a device used to heat metal to a specific temperature, softening it to facilitate forging and shaping.
[0003] In existing technologies, to preheat metal materials before forging, a feeding structure is needed to transport the metal parts into the forging furnace for heating. The feeding mechanism is mostly a mechanical clamping arm, which can hold the workpiece to be heated and then transport it into the furnace for heating. However, when the mechanical clamping arm is feeding the workpiece, it will be close to the furnace. The high temperature in the furnace will cause the workpiece to age faster and easily cause rapid damage to the gas or oil circuit, affecting the stability of the equipment. In existing technologies, when irregularly shaped workpieces are fed through the mechanical clamping arm, the workpiece is prone to be biased to one side of the furnace, resulting in uneven heating of the workpiece, which can easily affect the forging quality of the workpiece. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a forging furnace equipment with workpiece centering and automatic feeding.
[0005] The technical solution adopted to solve the above technical problems is: an automatic feeding and centering device for a forging heating machine for complex structural parts, including a forging furnace body for heating the workpiece, two symmetrically arranged fixed support platforms are provided at the feed inlet position of the forging furnace body, and a feeding support structure for support and guidance is provided between the two fixed support platforms.
[0006] Through the above technical solution, the two symmetrically arranged fixed support platforms provide a stable installation foundation for the entire feeding and centering structure. The feeding support structure extends from between the two fixed support platforms to the feed inlet of the forging furnace body, which can bear the workpiece to be heated and push the workpiece smoothly into the furnace along the support guide direction. There is no need for mechanical clamping arms to extend into the furnace to complete the feeding. Structurally, this avoids the problem of the feeding structure being aged and damaged by the high temperature of the furnace for a long time, and improves the stability of equipment operation.
[0007] A workpiece bearing structure for conveying workpieces is slidably connected above the feeding support structure. Two symmetrically arranged automatic centering blocks are fixedly connected on the upper surface of the two fixed support platforms on both sides of the feeding support structure and the workpiece bearing structure.
[0008] Through the above technical solution, the workpiece bearing structure is used to support the complex structural parts to be heated. When the workpiece bearing structure drives the workpiece to move towards the feed port of the forging furnace, the two sides of the workpiece will contact the inner inclined surfaces of the two automatic centering blocks. The inclined surfaces will apply a pushing force towards the center to the workpiece in the offset position, and finally push the workpiece to the center position of the feeding path to achieve automatic centering. This avoids the problem of uneven heating caused by the workpiece shifting to one side of the furnace, and ensures the forging quality of the workpiece.
[0009] Furthermore, the inner sides of the two automatic centering blocks are inclined, and a number of evenly distributed fixed support legs are fixedly connected to the lower surface of the two fixed support platforms. A reset platform is fixedly connected between the two fixed support platforms on the side away from the forging furnace body.
[0010] Through the above technical solution, the inner side of the automatically aligning block is tilted so that the workpiece can be gradually pushed to the center position as the workpiece carrier structure moves, thus completing the automatic alignment action. The evenly distributed fixed support legs provide stable support for the two fixed support platforms, ensuring the stability of the overall structure of the device. The reset platform is located at the beginning of the feeding path, which makes it convenient for the workpiece carrier structure to return to this position after feeding, waiting for the transfer robot arm to place the next batch of workpieces to be heated, thus realizing continuous feeding operation.
[0011] Furthermore, a transfer robotic arm for clamping and transferring workpieces is provided on any side of the reset platform at a position away from the forging furnace body.
[0012] With the above technical solution, the transfer robotic arm only needs to complete the material picking and unloading operations at the reset platform position, without having to extend into the furnace chamber of the forging furnace. This avoids the robotic arm being baked at high temperatures for a long time, thus accelerating its aging and improving the service life of the equipment.
[0013] Furthermore, the workpiece bearing structure includes a bearing platform body. The upper surface of the bearing platform body is provided with a plurality of evenly distributed through heating holes on the side near the forging furnace body. Two symmetrically arranged positioning block bodies are fixedly connected to the upper surface of the bearing platform body on the side away from the forging furnace body from the plurality of through heating holes. The inner sides of the two positioning block bodies are inclined.
[0014] Through the above technical solution, the through heating hole allows the heat in the furnace to pass through the main body of the support platform, making the workpiece placed on the main body of the support platform more evenly heated, and avoiding insufficient heating of the bottom of the workpiece due to being blocked by the main body of the support platform. The two symmetrically arranged and inwardly inclined positioning blocks can first perform preliminary centering and positioning of the workpiece placed on the main body of the support platform. With the subsequent secondary centering adjustment of the automatic centering block, the centering accuracy of complex structural parts is improved, and the workpiece is prevented from slipping when the main body of the support platform tilts.
[0015] Furthermore, the upper surface of the support platform body is fixedly connected with several evenly distributed support protrusions located between the through heating holes, and the support platform body is made of high alumina brick material.
[0016] Through the above technical solution, the supporting protrusion can lift the workpiece as a whole away from the upper surface of the support platform, so that the heat in the furnace can flow between the bottom of the workpiece and the surface of the support platform, further improving the uniformity of the workpiece heating. The high alumina brick has excellent high temperature resistance and structural strength, and can work stably in the high temperature environment at the furnace mouth for a long time without deformation or damage, reducing the replacement and maintenance cost of the workpiece support structure.
[0017] Furthermore, a connecting slide is fixedly connected to the lower surface of the bearing platform body at the middle position on the side away from the forging furnace body, a linkage slider is slidably connected through the lower surface of the connecting slide, and a rotating connecting block is rotatably connected to the center position of the lower surface of the linkage slider.
[0018] With the above technical solution, when the feeding support structure is inclined, the linkage slider can slide adaptively in the connecting slide cylinder. With the rotation compensation of the rotating connecting block, the angle and displacement deviation generated during the movement of the main body of the bearing platform are offset, ensuring the smooth movement of the main body of the bearing platform, avoiding jamming and damage to the pushing structure, and further improving the stability of the device operation.
[0019] Furthermore, an electric linear slide rail is fixedly connected between the two fixed support platforms and at the lower position, and the slider of the electric linear slide rail is rotatably connected to the rotating connecting block.
[0020] Through the above technical solution, the electric linear guide rail can drive the rotating connecting block to make uniform linear motion through the slider, thereby driving the workpiece bearing structure to complete the feeding and resetting actions along the feeding support structure. The transmission process is smooth and controllable, and can accurately control the conveying position of the workpiece, ensuring the accuracy and reliability of the feeding action.
[0021] Furthermore, the feeding support structure includes a support platform body fixedly connected between two fixed support platforms. A through sliding groove is provided through the middle of the upper surface of the support platform body, and two symmetrically arranged roller mounting grooves are provided through the upper surface of the support platform body on both sides of the through sliding groove.
[0022] Through the above technical solution, the through sliding groove provides moving space for the rotating connecting block, connecting slide cylinder and linkage slider, so that the power of the lower electric linear slide rail can be smoothly transmitted to the upper workpiece bearing structure. The two symmetrically arranged roller mounting grooves provide a stable installation position for the supporting conveying rollers, ensuring that the supporting conveying rollers are installed in an accurate position and that the rolling process is smooth.
[0023] Furthermore, several evenly distributed support conveying rollers are rotatably connected to the two roller mounting slots, and the workpiece bearing structure is rolled at the support conveying roller positions. The main body of the support platform is tilted and raised from the reset platform position to the furnace mouth position of the forging furnace body. The part of the main body of the support platform extending to the forging furnace body is kept horizontal with the ground. The roller mounting slot and the through sliding slot extend to the horizontal position.
[0024] Through the above technical solution, the evenly distributed support conveying rollers can convert the sliding friction between the workpiece bearing structure and the support platform body into rolling friction, effectively reducing the resistance encountered when pushing the workpiece bearing structure to move, reducing the load on the electric linear slide rail, improving the smoothness of the device operation, and extending the service life of the equipment. The inclined and raised support platform body transitions from the reset platform to the furnace mouth, which allows the workpiece that is stuck between the two automatic centering blocks to be lifted and moved when the workpiece is large and not directly placed on the surface of the workpiece bearing structure.
[0025] The beneficial effects of the present invention are as follows: (1) The present invention supports the workpiece through the workpiece bearing structure, and the workpiece bearing structure is moved along the feeding support structure by the electric linear slide rail, so as to transport the workpiece to the furnace chamber of the forging furnace body. The transfer robot arm only needs to complete the loading and unloading at the reset platform position far away from the furnace chamber, without having to extend into the furnace chamber. This avoids the feeding structure being baked by the high temperature of the furnace chamber for a long time, which accelerates aging and damage, and improves the stability and service life of the equipment. (2) The present invention uses two inner inclined automatic centering blocks to automatically push the offset workpiece to the feeding center position during the process of the workpiece moving into the furnace chamber. It works in conjunction with the inner inclined positioning block body on the workpiece bearing structure to complete the initial centering, which can realize the automatic centering and positioning of complex structural parts, avoid the workpiece shifting to one side of the furnace chamber and causing uneven heating, and ensure the quality of subsequent forging processing of the workpiece. (3) The present invention provides uniformly distributed through heating holes on the main body of the workpiece bearing structure. The workpiece is lifted off the surface of the main body of the bearing platform by the support protrusion, so that the heat in the furnace can flow from the bottom of the workpiece, ensuring that the workpiece is heated evenly. At the same time, the main body of the bearing platform is made of high temperature resistant high alumina brick, which can work stably in a high temperature environment for a long time, reducing the maintenance and replacement cost of the device.

Detailed Implementation
[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0035] like Figure 1-7 As shown in the figure, an automatic feeding and centering device for a forging heating machine for complex structural parts in this embodiment includes a forging furnace body 1 for heating the workpiece. Two symmetrically arranged fixed support platforms 2 are provided at the feed inlet of the forging furnace body 1. A feeding support structure 9 for support and guidance is provided between the two fixed support platforms 2. The two symmetrically arranged fixed support platforms 2 provide a stable installation foundation for the entire feeding and centering structure. The feeding support structure 9 extends from between the two fixed support platforms 2 to the feed inlet of the forging furnace body 1, and can bear the workpiece to be heated and push the workpiece smoothly into the furnace along the support and guidance direction. There is no need for mechanical clamps to extend into the furnace to complete the feeding. Structurally, this avoids the problem of the feeding structure being aged and damaged by long-term baking at high temperature in the furnace, and improves the stability of equipment operation.
[0036] The feeding support structure 9 includes a support platform body 90 fixedly connected between two fixed support platforms 2. A through sliding groove 93 is provided through the middle of the upper surface of the support platform body 90. Two symmetrically arranged roller mounting grooves 92 are provided through the upper surface of the support platform body 90 on both sides of the through sliding groove 93. The through sliding groove 93 provides moving space for the rotating connecting block 66, the connecting slide cylinder 64 and the linkage slider 65, so that the power of the lower electric linear slide rail 7 can be smoothly transmitted to the upper workpiece bearing structure 6. The two symmetrically arranged roller mounting grooves 92 provide a stable installation position for the support conveying rollers 91, ensuring that the installation position of the support conveying rollers 91 is accurate and the rolling process is smooth.
[0037] Two roller mounting slots 92 are rotatably connected to several evenly distributed support conveying rollers 91, and the workpiece bearing structure 6 is rolled at the support conveying rollers 91. The support platform body 90 is tilted and raised from the reset platform 8 to the furnace mouth of the forging furnace body 1. The part of the support platform body 90 extending to the forging furnace body 1 remains horizontal with the ground. The roller mounting slots 92 and the through sliding grooves 93 extend to the horizontal position. The evenly distributed support conveying rollers 91 can convert the sliding friction between the workpiece bearing structure 6 and the support platform body 90 into rolling friction, effectively reducing the friction of pushing the workpiece bearing structure 6. The resistance encountered during movement reduces the load on the electric linear guide rail 7, improves the smoothness of the device's operation, and extends the service life of the equipment. The inclined and raised support platform body 90 transitions from the reset platform 8 to the furnace opening, which allows the workpiece, which is large and not directly placed on the surface of the workpiece bearing structure 6, to be lifted and moved between the two automatic centering blocks 4. The roller mounting groove 92 and the through sliding groove 93 extend to the horizontal position, so that the part of the support platform body 60 with the through heating hole 62 can enter the forging furnace body 1, while the part without the through heating hole 62 does not enter the forging furnace body 1.
[0038] Above the feeding support structure 9, a workpiece bearing structure 6 for conveying workpieces is rolled and connected. On the upper surfaces of the two fixed support platforms 2, two symmetrically arranged automatic centering blocks 4 are fixedly connected on both sides of the feeding support structure 9 and the workpiece bearing structure 6. The workpiece bearing structure 6 is used to support the complex structural parts to be heated. When the workpiece bearing structure 6 moves the workpiece toward the feed port of the forging furnace body 1, the two sides of the workpiece will contact the inner inclined surfaces of the two automatic centering blocks 4. The inclined surfaces will apply a pushing force toward the center to the workpiece in the offset position, and finally push the workpiece to the center position of the feeding path to achieve automatic centering. This avoids the problem of uneven heating caused by the workpiece shifting to one side of the furnace and ensures the forging quality of the workpiece.
[0039] The workpiece bearing structure 6 includes a bearing platform body 60. Several evenly distributed through heating holes 62 are opened on the upper surface of the bearing platform body 60 near the forging furnace body 1. Two symmetrically arranged positioning block bodies 63 are fixedly connected to the upper surface of the bearing platform body 60 on the side away from the forging furnace body 1 where the through heating holes 62 are located. The inner sides of the two positioning block bodies 63 are inclined. The through heating holes 62 allow heat from the furnace to pass through the bearing platform body 60, making the workpiece placed on the bearing platform body 60 more evenly heated and preventing insufficient heating of the bottom of the workpiece due to being blocked by the bearing platform body 60. The two symmetrically arranged and inwardly inclined positioning block bodies 63 can initially center and position the workpiece placed on the bearing platform body 60. With the subsequent secondary centering adjustment by the automatic centering block 4, the centering accuracy of complex structural parts is improved, and the workpiece is prevented from slipping when the bearing platform body 60 tilts.
[0040] Several evenly distributed support protrusions 61 are fixedly connected to the upper surface of the support platform body 60 between the through heating holes 62. The support platform body 60 is made of high alumina brick material. The support protrusions 61 can lift the workpiece as a whole away from the upper surface of the support platform body 60, so that the heat in the furnace can flow between the bottom of the workpiece and the surface of the support platform body 60, further improving the uniformity of the workpiece heating. High alumina brick has excellent high temperature resistance and structural strength, and can work stably in the high temperature environment at the furnace mouth for a long time without deformation or damage, reducing the replacement and maintenance cost of the workpiece support structure 6.
[0041] A connecting slide cylinder 64 is fixedly connected to the lower surface of the main body 60 of the bearing platform at the middle position on the side away from the main body 1 of the forging furnace. A linkage slider 65 is slidably connected through the lower surface of the connecting slide cylinder 64. A rotating connecting block 66 is rotatably connected to the center position of the lower surface of the linkage slider 65. When the feeding support structure 9 is tilted as a whole, the linkage slider 65 can slide adaptively within the connecting slide cylinder 64. With the rotation compensation of the rotating connecting block 66, the angular and displacement deviations generated during the movement of the main body 60 of the bearing platform are offset, ensuring the smooth movement of the main body 60 of the bearing platform, avoiding jamming and damage to the pushing structure, and further improving the stability of the device operation.
[0042] An electric linear slide rail 7 is fixedly connected between two fixed support platforms 2 and at the bottom position. The slider of the electric linear slide rail 7 is rotatably connected to the rotating connecting block 66. The electric linear slide rail 7 can drive the rotating connecting block 66 to make uniform linear motion through the slider, thereby driving the workpiece bearing structure 6 to complete the feeding and resetting action along the feeding support structure 9. The transmission process is smooth and controllable, and can accurately control the conveying position of the workpiece, ensuring the accuracy and reliability of the feeding action.
[0043] The inner sides of the two automatic centering blocks 4 are inclined. Several evenly distributed fixed support legs 3 are fixedly connected to the lower surface of the two fixed support platforms 2. A reset platform 8 is fixedly connected between the two fixed support platforms 2 on the side away from the forging furnace body 1. The inclined inner side of the automatic centering blocks 4 can gradually push the workpiece to the center position when the workpiece moves with the workpiece bearing structure 6, thus completing the automatic centering action. The evenly distributed fixed support legs 3 provide stable support for the two fixed support platforms 2, ensuring the stability of the overall structure of the device. The reset platform 8 is located at the beginning of the feeding path, which makes it convenient for the workpiece bearing structure 6 to return to this position after feeding, waiting for the transfer robot arm 5 to place the next batch of workpieces to be heated, thus realizing continuous feeding operation.
[0044] A transfer robotic arm 5 for clamping and transferring workpieces is provided on any side of the reset platform 8 and at a position away from the forging furnace body 1. The transfer robotic arm 5 only needs to complete the material picking and unloading operation at the reset platform 8 position, without needing to extend into the furnace chamber of the forging furnace. This avoids the robotic arm being baked at high temperature for a long time, which accelerates aging and improves the service life of the equipment.
[0045] The working principle of this embodiment is as follows: The transfer robotic arm 5 places the workpiece to be heated on the support platform body 60 of the workpiece support structure 6, which has returned to the reset platform position 8. Then, the electric linear slide rail 7 is activated, and the slider drives the rotating connecting block 66 to move. The rotating connecting block 66 drives the linkage slider 65, the connecting slide cylinder 64, and the support platform body 60 to move along the support conveying roller 91 towards the forging furnace body 1. During the process, the support conveying roller 91 converts sliding friction into rolling friction, reducing the moving resistance. When the two sides of the workpiece contact the inclined inner sides of the two automatic centering blocks, the automatic centering blocks push the offset workpiece towards the feeding center to complete the secondary centering. Finally, the workpiece moves together with the support platform body 60 to the designated position in the furnace chamber of the forging furnace body 1 and begins heating. During the heating process, the heat in the furnace chamber flows through the through heating hole 62, and the support protrusion 61 lifts the workpiece away. The surface of the main body 60 of the support platform ensures uniform heating of the workpiece. After heating, the electric linear slide rail 7 drives the workpiece support structure 6 back to the reset platform 8 position, and the transfer robotic arm 5 removes the heated workpiece, thus completing one loading, centering, and heating operation, and waiting for the next loading. During this process, the positioning block body 63 can effectively prevent the workpiece from slipping when the main body 60 of the support platform tilts. The positioning block body 63 effectively limits the workpiece, and when a large workpiece is stuck between the automatic centering blocks 4, the workpiece can be placed slightly towards the position of the forging furnace body 1. The slope of the support platform body 90 can lift the main body 60 of the support platform, allowing the workpiece to be lifted. When the workpiece is placed between the two automatic centering blocks 4, its lowest position should be lower than the surface height of the inner bottom wall of the forging furnace body 1 to prevent the workpiece from being unable to be lifted by the main body 60 of the support platform.
[0046] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
