Description

Technical Field

[0001] This application relates to the field of bearing forging technology, and more specifically, to an ejector braking device on a bearing forging die. Background Technology

[0002] Forging is a processing method that uses forging machinery to apply pressure to metal billets, causing them to undergo plastic deformation to obtain forgings with certain mechanical properties, shapes, and dimensions. It is one of the two major components of forging. Forging can eliminate defects such as casting porosity generated during the smelting process, optimize the microstructure, and because it preserves the complete metal flow lines, the mechanical properties of forgings are generally superior to those of castings made of the same material.

[0003] For example, Chinese Patent Publication No. CN118635433A discloses the following technical solution: a pre-forming forging device for wind turbine bearing forgings, including a forging table, with horizontal plates fixedly installed on both sides of the middle of the forging table. The horizontal plate on the right side is provided with a storage structure and a pushing structure, and the horizontal plate on the left side is provided with a material collection structure. A top material structure is provided in the middle of the forging table, and a transmission structure is provided between the top material structure and the pushing structure. The pushing structure can push the forging to be forged stored in the storage structure to the top material structure, and the top material structure pushes the forging to be forged into the forging limit ring.

[0004] Addressing the problems with existing technologies: When the aforementioned device pushes the forging from the storage structure to the forging position, positional deviations are prone to occur, affecting the precision and quality of forging. Furthermore, the power transmission and reset mechanism of the ejector structure may not be perfect, resulting in insufficient reliability and stability of the ejector action after forging is completed. Summary of the Invention

A top-feeding plate is fixedly connected to the bottom of the movable rod.

[0011] Preferably, a spring B is movably sleeved on the outer wall of the mounting shaft, and the two ends of the spring B are fixedly connected to the worktable and the movable plate, respectively.

[0012] Preferably, one side of the movable plate is trapezoidal and the upper end of that side is inclined, and the roller A is in contact with the upper side of the movable plate.

[0013] Preferably, a storage and transportation assembly is provided on the inner side of the support leg. The storage and transportation assembly includes a guide frame, which is fixedly connected to the side of the fixed mold. A guide bucket is fixedly connected to the other side of the guide frame. A discharge channel is fixedly connected to the bottom of the guide bucket. A storage cart is provided at the bottom of the discharge channel. Multiple storage slots are provided at the upper end of the storage cart. An installation block is fixedly connected to the outer wall of one side of the support leg.

[0015] Preferably, a mounting rod is fixedly connected to the inner side of the support leg, and a speed reduction plate is fixedly connected to the other end of the mounting rod, with the inner side of the speed reduction plate fitting against the storage vehicle.

[0016] The advantages of this application are: (1) This application realizes the automatic feeding function of raw materials during the forging process by setting up a toothed plate, toothed ring, ratchet and connecting rod mechanism driven by a cylinder. When the cylinder drives the pressure plate to press down for forging, the toothed ring and ratchet are driven by the connecting rod A and the toothed plate to drive the conveying plate to accurately feed the raw materials in the storage cylinder into the fixed mold; when the cylinder rises, the pawl slides on the back of the ratchet teeth to prevent the conveying plate from resetting, and at the same time the next raw material in the storage cylinder automatically falls into the conveying plate to prepare for the next feeding. This structure realizes the linkage between feeding and pressing actions, improves production efficiency, ensures the accuracy of feeding position, and realizes unidirectional motion control by using the ratchet mechanism to avoid return interference and enhance the stability and continuity of equipment operation.

[0017] (2) This application adds an ejector assembly. The moving plate is driven to slide along the mounting shaft by the lifting motion of the connecting rod A, and the inclined surface of the movable plate cooperates with the rollers to drive the moving rod and the ejector plate to move up and down. When the pressure plate presses down forging, the ejector plate retracts into the mold to avoid interference; after forging is completed, the cylinder rises and drives the ejector plate to rise, ejecting the finished workpiece out of the mold, realizing automatic demolding. This design uses the existing cylinder power to complete the ejection action without the need for an additional power source. It has a compact structure and high efficiency, which significantly improves the automation level and production efficiency of demolding. At the same time, the spring B ensures that the moving plate is reset, ensuring the reliability and stability of the ejection action.

[0018] (3) This application includes a storage and transportation component. The reciprocating motion of the moving plate drives the rotating shaft B to rotate, which in turn drives the mounting cylinder and the movable rod to rotate, thereby pushing the storage cart to move gradually. When the moving plate resets, the movable rod pushes the fixed rod to move the storage cart one station forward, moving the next empty storage slot below the unloading channel to receive the forged workpiece. When the moving plate moves forward, the movable rod retracts without pushing the storage cart, realizing unidirectional stepping conveying. This structure utilizes existing power to achieve automatic collection and transfer of workpieces, reducing manual intervention and improving production continuity. The speed reduction plate effectively controls the inertia of the storage cart, ensuring positioning accuracy, and the whole process is fully automated from forging and unloading to collection.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Example 1, please refer to Figures 1-8 This embodiment provides an ejector braking device for a bearing forging die, comprising: a worktable 1; a support leg 2, the support leg 2 being fixedly connected to the bottom of the worktable 1; a fixing column 3, the fixing column 3 being fixedly connected to the upper end of the worktable 1; a top plate 4, the top plate 4 being fixedly connected to the top of the fixing column 3; a cylinder 51 being fixedly connected to the top of the top plate 4; a pressure plate 52 being fixedly connected to the output shaft of the cylinder 51; and a fixing die 53 being fixedly connected to the upper end of the worktable 1. A connecting rod A61 is fixedly connected to the outer wall of the output shaft of cylinder 51. The other end of the connecting rod A61 movably passes through the top plate 4 and is fixedly connected to a toothed plate 62. A fixed plate 617 is fixedly connected to the upper end of the top plate 4. A ratchet 63 and a toothed ring 64 are rotatably connected to the front end of the fixed plate 617. A rotating shaft A65 is fixedly connected to the outer wall of the ratchet 63. A connecting rod A66 is fixedly connected to the other end of the rotating shaft A65. A connecting rod B67 is hinged to the other end of the connecting rod A66 via a pin. A pawl 68 is hinged to the inner wall of the toothed ring 64. A connecting rod B69 is hinged to the other end of the connecting rod B67 via a pin. A connecting shaft 610 is fixedly connected to the inner side of the connecting rod B69. A material conveying plate 611 is fixedly connected to the other end of the connecting shaft 610. A material discharge port 612 is opened at the upper end of the top plate 4. A material storage cylinder 613 is fixedly connected to the bottom of the top plate 4. A horizontal plate 615 is fixedly connected to the side of the fixed mold 53.

[0028] A limiting plate 614 is fixedly connected to the upper end of the top plate 4, and the connecting rod B69 slides through the limiting plate 614, thereby realizing the relative sliding function between the connecting rod B69 and the limiting plate 614. This design not only ensures that the connecting rod B69 can move freely, but also effectively limits its range of motion through the limiting plate 614, ensuring that the stability and functionality of the entire structure can be fully utilized.

[0029] The inner side of the conveyor plate 611 has a circular opening, which matches the inner diameter of the fixed mold 53. The bottom of the conveyor plate 611 fits against the upper end of the horizontal plate 615. The size of this circular opening is designed very precisely, and its diameter is exactly the same as the inner diameter of the fixed mold 53, thus ensuring that the two can perfectly match during assembly or use, avoiding any deviation or mismatch. A spring A616 is fixedly connected to the inner wall of the toothed ring 64, and the other end of the spring A616 is fixedly connected to the pawl 68.

[0030] In use, multiple raw materials are first placed into the storage cylinder 613 through the discharge port 612. At this time, the lowest raw material will enter the circular opening of the conveyor plate 611, which will then activate the cylinder 51 to drive the pressure plate 52 to descend. During the downward movement of the pressure plate 52, the output shaft of the cylinder 51 will drive the connecting rod A61 fixed on the outer wall to move downward synchronously. After the connecting rod A61 passes through the top plate 4, it pushes the toothed plate 62 to move downward. The toothed plate 62 meshes with the toothed ring 64, and its downward movement will drive the toothed ring 64 to rotate counterclockwise. At this time, the pawl 68 on the inner wall of the toothed ring 64 is engaged with the ratchet 63 under the action of the spring A616, thereby driving the ratchet 63 to rotate synchronously. When the ratchet 63 rotates, it drives the connecting rod A66 to rotate around the axis of the axis A65 via the rotating shaft A65. The connecting rod A66 pulls one end of the connecting rod B67 to rotate around the rotating shaft A65 via the pin. In turn, the connecting rod B67 drives the connecting rod B69 to slide horizontally back and forth along the limiting plate 614, so that the conveying plate 611 moves from below the storage cylinder 613 to directly above the fixed mold 53, accurately feeding the raw material in the circular opening into the fixed mold 53. This action will be completed when the pressure plate 52 moves to the middle. As the pressure plate 52 continues to descend, the rotating shaft A65, connecting rod A66, and connecting rod B67 will continue to rotate counterclockwise. When the pressure plate 52 finishes pressing, all of the above components will rotate back to their original positions, thereby driving the connecting rod B69 to move in the opposite direction, so that the conveying plate 611 is reset from directly above the fixed mold 53 to below the storage cylinder 613. At this time, the next raw material in the storage cylinder 613 will fall into the circular opening of the conveying plate 611 under the action of gravity, waiting for the next feeding. When cylinder 51 drives pressure plate 52 to rise and reset, connecting rod A61 moves upward, pulling toothed plate 62 upward. Toothed plate 62 meshes with toothed ring 64, driving toothed ring 64 to rotate clockwise. At this time, pawl 68 slides on the back of ratchet 63's teeth and compresses spring A616, preventing ratchet 63 from rotating. This avoids reverse movement of conveyor plate 611, ensuring the entire device remains stable during the rise of pressure plate 52 and does not interfere with the already pressed workpiece. Horizontal plate 615 effectively supports the bottom of conveyor plate 611 during its movement, preventing it from tilting due to the weight of the raw material or its inertia. This ensures the raw material falls accurately into the fixed mold 53, improving the stability and continuity of the entire forging process. Cylinder 51 drives connecting rod A61 and toothed plate 62 to move upward. Toothed plate 62 drives toothed ring 64 to rotate counterclockwise. At this time, pawl 68 compresses spring A616 under the action of the inclined surface of ratchet 63 and disengages from ratchet 63. Ratchet 63 remains stationary to prevent conveyor plate 611 from moving upward and resetting. This ensures that the raw material can fall smoothly into the circular opening of conveyor plate 611 before the next feeding, realizing the continuous automatic feeding cycle.

[0031] Example 2, please refer to Figures 1-8 Based on Embodiment 1, a top-feeding assembly 8 is assembled on the side and bottom of the workbench 1. The top-feeding assembly 8 includes a mounting shaft 81, which is fixedly connected to the outer wall of the workbench 1. A movable plate 82 is slidably connected to the outer wall of the mounting shaft 81. A guide groove 83 is provided on the inner side of the movable plate 82. A lifting rod 84 is fixedly connected to the outer wall of the connecting rod A61. A sliding shaft 85 is fixedly connected to the outer wall of the lifting rod 84. The outer wall of the sliding shaft 85 is slidably connected to the inner wall of the guide groove 83. A movable plate 86 is fixedly connected to the bottom of the movable plate 82. A movable rod 87 slides through the middle of the workbench 1. A roller A88 is provided at the bottom of the movable rod 87. A top-feeding plate 89 is fixedly connected to the bottom of the movable rod 87.

[0032] A spring B810 is movably sleeved on the outer wall of the mounting shaft 81. The two ends of the spring B810 are fixedly connected to the worktable 1 and the moving plate 82, respectively. This design can not only effectively utilize the elasticity of the spring B810, but also ensure the coordinated operation of various components during the working process, further improving the overall work efficiency and accuracy.

[0033] One side of the movable plate 86 is trapezoidal and the upper end of the side is inclined. The roller A88 is attached to the upper side of the movable plate 86. The roller A88 is precisely installed on the upper side of the movable plate 86 and is in close contact with its surface, thereby ensuring smooth and stable contact between the two.

[0034] In use, when the output shaft of cylinder 51 drives the pressure plate 52 to descend for forging, the connecting rod A61 moves down synchronously, and the lifting rod 84 on its outer wall moves down accordingly. The sliding shaft 85 on the lifting rod 84 slides in the guide groove 83 on the inner side of the moving plate 82. Due to the trajectory design of the guide groove 83, the downward movement of the sliding shaft 85 will push the moving plate 82 to move along the mounting shaft 81 towards the worktable 1. At this time, the moving plate 82 compresses the spring B810. The movable plate 86 at the bottom of the moving plate 82 moves synchronously. Because one side of the movable plate 86 is trapezoidal and the upper end is provided with an inclined surface, the roller A88 that is in contact with the upper side of the movable plate 86 gradually moves down under the action of the inclined surface, driving the moving rod 87 and the top plate 89 to move down, so that the top plate 89 retracts into the fixed mold 53 to avoid interference with the forging process. When forging is completed, cylinder 51 drives pressure plate 52 to rise and reset, connecting rod A61 and lifting rod 84 move upward, sliding shaft 85 slides in the opposite direction in guide groove 83, compressed spring B810 releases elastic potential energy, pulls moving plate 82 to reset along mounting shaft 81, moving plate 86 moves away from worktable 1, and moving rod 87 gradually moves upward under the action of inclined plane, pushing the forged workpiece out of fixed mold 53, realizing automatic ejection function. When transporting new raw material workpieces, conveying plate 611 can push the die-cast bearing from above fixed mold 53 into guide frame 71.

[0035] Example 3, please refer to Figures 1-8 Based on Embodiment 1, a storage and transportation component 7 is provided on the inner side of the support leg 2. The storage and transportation component 7 includes a guide frame 71, which is fixedly connected to the side of the fixed mold 53. A guide bucket 72 is fixedly connected to the other side of the guide frame 71. A discharge channel 73 is fixedly connected to the bottom of the guide bucket 72. A storage cart 74 is provided at the bottom of the discharge channel 73. Multiple storage slots are opened at the upper end of the storage cart 74. An installation block 75 is fixedly connected to the outer wall of one side of the support leg 2. A rotating shaft B76 rotatably passes through the middle of the installation block 75. The rotating shaft B76 is close to the storage cart. One end of the 74 is fixedly connected to an installation cylinder 77, and a movable rod 78 is slidably connected inside the installation cylinder 77. A connecting rod C710 is fixedly connected to the outer wall of the movable plate 82, and a movable cylinder 711 is fixedly connected to the other end of the connecting rod C710. The movable cylinder 711 is movably sleeved on the outside of the rotating shaft B76. A spiral groove 712 is opened on the outer wall of the rotating shaft B76. A movable shaft 713 is fixedly connected to the inner wall of the movable cylinder 711. The movable shaft 713 is slidably connected inside the spiral groove 712. Multiple fixed rods 714 are fixedly connected to the side of the storage cart 74 near the rotating shaft B76.

[0036] A spring C79 is fixedly connected to the inner wall of the mounting cylinder 77. The top of the spring C79 is fixedly connected to the bottom of the movable rod 78, and one side of the movable rod 78 is set as an inclined surface. A mounting rod 715 is fixedly connected to the inner side of the support leg 2. A speed reduction plate 716 is fixedly connected to the other end of the mounting rod 715. The inner side of the speed reduction plate 716 is in close contact with the storage vehicle 74. The inner part of the speed reduction plate 716 is tightly attached to the storage vehicle 74. This contact can effectively decelerate the storage vehicle 74, thereby ensuring the stability and safety of the entire structure during operation.

[0037] In use, when the movable plate 82 moves towards the worktable 1, the connecting rod C710 fixed on its outer wall drives the movable cylinder 711 to move synchronously along the rotating shaft B76. The movable shaft 713 on the inner wall of the movable cylinder 711 slides in the spiral groove 712, driving the rotating shaft B76 to rotate. When the rotating shaft B76 rotates, it drives the mounting cylinder 77 to rotate synchronously. The movable rod 78 inside the mounting cylinder 77 rotates with it. When the movable rod 78 rotates towards the middle of the worktable 1, it contacts the fixed rod 714 on one side of the storage cart 74. The inclined surface of the movable rod 78 will abut against the fixed rod 714. Under the action of rotational force, the movable rod 78 compresses the spring C79 and retracts into the mounting cylinder 77. After passing the fixed rod 714, the spring C79 returns to its original position and pushes the movable rod 78 out. At this time, it will not move the storage cart 74 through the cooperation of the movable rod 78 and the fixed rod 714. When the moving plate 82 returns to its original position away from the worktable 1, the connecting rod C710 drives the moving cylinder 711 to move in the opposite direction, and the movable shaft 713 slides in the opposite direction within the spiral groove 712, causing the rotating shaft B76 to drive the mounting cylinder 77 to rotate in the opposite direction. At this time, the movable rod 78 rotates with the mounting cylinder 77 away from the center of the worktable 1, and its inclined surface no longer contacts the fixed rod 714. Instead, the other side of the movable rod 78 abuts against the fixed rod 714. During the rotation, the movable rod 78 cannot retract, thereby pushing the fixed rod 714 to move the storage cart 74 a certain distance away from the worktable 1, so that the next storage slot on the storage cart 74 moves directly below the unloading channel 73 to receive the next forged workpiece. During the movement, the side of the storage cart 74 is in contact with the deceleration plate 716. The deceleration plate 716 buffers and limits the movement of the storage cart 74, preventing the storage cart 74 from deviating from directly below the unloading channel 73 due to excessive inertial movement. Once the storage slots on the storage cart 74 are full of workpieces, the storage cart 74 can be moved out from the inside of the support leg 2 for unified transfer and processing of the workpieces.

[0038] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
