Description

Technical Field

[0001] This utility model relates to the field of forging technology, specifically to a forging transfer mechanism. 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 and pressing (forging and stamping). Forging can eliminate defects such as casting porosity generated during the smelting process and optimize the microstructure. At the same time, 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. Important parts in related machinery that are subject to high loads and harsh working conditions are mostly made of forgings, except for simpler shapes that can be made of rolled plates, profiles, or welded parts. The use of forging transfer trolleys is indispensable in the transfer and transportation of forgings.

[0003] A search revealed a forging transfer device with application number 202222909888.3. This device has a motor fixedly connected to the lower side of a support frame. The motor's output shaft passes through the middle of the support frame, and the end of the motor's output shaft is fixedly connected to the lower end of a lead screw. The lead screw is threadedly connected to the lower part of a rectangular frame, and a sleeve is fixedly connected to the upper side of the rectangular frame. Symmetrical circular guide rods are fixedly connected to the lower sides of the sleeves. Two circular guide rods are respectively placed inside corresponding circular sleeves, and the lower ends of the two circular sleeves are fixedly connected to the upper side of the support frame. This facilitates the transfer of forgings. However, during clamping, the high temperature emitted by the forgings can cause burns to workers. Furthermore, the forgings are directly exposed during transfer, causing their temperature to drop too quickly, which is detrimental to subsequent forging. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a forging transfer mechanism to solve the technical problems in the background art mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a forging transfer mechanism, comprising a frame, a rack mounted on one side of the top of the frame via a mounting plate, a placement frame connected to the top of the frame via a lifting mechanism, and rotating shafts connected to both sides of the placement frame, a gear connected to one end of each rotating shaft, a heat insulation cover connected to the outside of the rotating shaft, a hydraulic cylinder mounted in the middle of the top of the frame via a heat insulation box, and the output end of the hydraulic cylinder penetrating the heat insulation box and connected to the lifting mechanism, a rotating frame connected to the top of the frame via a support frame, a pull rod connected inside the rotating frame via two limit wheels, and a high-temperature resistant mechanical gripper mounted on one end of each pull rod.

[0006] Further, a handle is connected to one side of the support frame, and universal wheels are installed at the bottom of the frame. The number of the universal wheels is four, and the four universal wheels are distributed in a rectangular array.

[0007] By adopting the above technical solution, the staff can push the handle, and under the drive of the universal wheels, transfer the frame to the designated position, so as to facilitate the transportation of forgings. The rectangular array distribution of the universal wheels can make the frame move more smoothly.

[0008] Further, the rack is engaged with the gear.

[0009] By adopting the above technical solution, the staff starts the hydraulic cylinder through the control panel. The output end of the hydraulic cylinder pushes the lifting mechanism, causing the lifting mechanism to drive the placement rack to move upward. During the upward movement of the placement rack, the gear contacts and meshes with the rack, causing the gear to drive the rotating shaft to rotate, thereby driving the heat insulation cover to flip 180 degrees, opening the heat insulation cover to expose the tabletop of the placement rack, facilitating the staff to place the forgings on the tabletop of the placement rack. When the staff has placed the forgings, the output end of the hydraulic cylinder pulls the lifting mechanism, causing the lifting mechanism to drive the placement rack to move downward to return to the original position. At this time, the gear and the rack contact and mesh again, causing the rotating shaft to reverse and driving the heat insulation cover to flip to cover the tabletop of the placement rack and the forgings, avoiding the heat emitted from scalding the staff, and at the same time delaying the cooling rate of the forgings, achieving a certain heat preservation effect.

[0010] Further, both the gear and the rack are made of heat-resistant steel.

[0011] By adopting the above technical solution, heat-resistant steel has good heat resistance. The gear and the rack made of heat-resistant steel can reduce the influence of the high temperature emitted by the forgings, and high-temperature resistant grease (such as Soco SVKV633) is coated on the outside of the gear and the rack to delay the wear of the gear and the rack and improve the service life.

[0012] Further, the heat insulation cover is rotationally connected to the placement rack through a rotating shaft.

[0013] By adopting the above technical solution, the heat insulation cover is made of stainless steel and has an aluminum foil reflective layer inside. The placement rack adopts a design of double-layer steel plates sandwiching ceramic fiber, which can significantly improve the heat preservation effect during the transportation of forgings and delay the temperature drop rate.

[0014] Further, the longitudinal section of the pull rod is in the shape of a "middle", and the inside of the pull rod is hollow.

[0015] By adopting the above technical solution, the worker pushes the pull rod to move the high-temperature resistant mechanical gripper to a suitable position, operates the control panel, and causes the hydraulic mechanism on the high-temperature resistant mechanical gripper to control the gripper to hold the high-temperature forging and place it on the placement rack. The "U"-shaped design, in conjunction with the limit wheel, limits the pull rod, allowing the pull rod to move the high-temperature resistant mechanical gripper back and forth to adjust its position. The pull rod extends the distance between the forging and the worker, preventing the high temperature of the forging from affecting the worker. At the same time, the limit wheel reduces the frictional resistance when the pull rod moves back and forth. The hollow design provides installation space for the hydraulic mechanism on the high-temperature resistant mechanical gripper and reduces the impact of temperature on the hydraulic mechanism. It also reduces the weight of the pull rod, making it lighter and easier to slide.

[0016] Furthermore, the limiting wheel is rotatably connected to the rotating frame.

[0017] By adopting the above technical solution, the operator can lift or press down the pull rod. With the cooperation of the limit wheel and the rotating rod, the pull rod can drive the high-temperature resistant mechanical gripper to rotate along the Z-axis to adjust the position of the high-temperature resistant mechanical gripper. By adjusting the rotation angle of the high-temperature resistant mechanical gripper, the gripping range of the high-temperature resistant mechanical gripper can be increased.

[0018] Furthermore, the rotating frame is Y-shaped and is rotatably connected to the support frame.

[0019] By adopting the above technical solution, while the high-temperature resistant mechanical gripper rotates along the Z-axis, the rotating frame and the support frame work together to allow the pull rod to drive the high-temperature resistant mechanical gripper to rotate along the Y-axis to adjust the position of the high-temperature resistant mechanical gripper, thereby improving the practicality of the device.

[0020] Furthermore, a control panel is provided on one side of the top of the pull rod, and the hydraulic cylinder and the high-temperature mechanical gripper are both electrically connected to the control panel.

[0021] By adopting the above technical solution, the high-temperature resistant mechanical gripper is the ALH63 / ALH80 two-finger long-stroke heavy-duty gripper from AINTE Technology. The operator starts and operates the high-temperature resistant mechanical gripper and hydraulic cylinder through the control panel to respectively realize the clamping of forgings and control the lifting and lowering of the placement rack, thereby avoiding the heat generated by the high-temperature forgings from burning the operator.

[0022] Furthermore, protective boxes are installed on both sides of the mounting plate, and the rotating shaft is slidably connected to the protective boxes.

[0023] By adopting the above technical solution, both the gear and rack are located inside the protective box, and a sliding groove for the shaft to move is opened on one side of the protective box. The protective box shields the gear and rack, preventing the oxide scale formed by oxidation on the outer surface of the forging from falling into the gear and rack tooth grooves during the transfer of the forging, which would affect the meshing of the gear and rack. At the same time, it catches the lubricating oil, preventing the slipping lubricating oil from falling directly to the ground and reducing consumption.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model is equipped with a lifting mechanism, gears, racks, a placement frame, and a heat insulation cover. Driven by the output end of the hydraulic cylinder, the lifting mechanism moves the placement frame up or down. During the up and down movement of the placement frame, the gears mesh with the racks, causing the gears to drive the rotating shaft to rotate forward or backward, thereby opening or closing the heat insulation cover. During the transfer process, the heat insulation cover covers the forgings to prevent the emitted heat from burning the workers, while also slowing down the cooling rate of the forgings and achieving a certain heat preservation effect.

[0026] 2. This utility model is equipped with a support frame, a pull rod, and a rotating frame. By moving the pull rod, the operator can adjust its length and angle with the help of the limit wheel, the rotating frame, and the support frame, thereby adjusting the position of the high-temperature resistant mechanical gripper. This makes it convenient for the operator to use the high-temperature resistant mechanical gripper to clamp the workpiece, avoiding the need for the operator to use pliers, thus improving work efficiency. In addition, the pull rod is long enough to prevent the operator from being affected by the high temperature. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of this utility model will be described below based on its overall structure.

[0035] Example 1: A forging transfer mechanism, such as Figures 1-5 As shown, the system includes a frame 1. A rack 10 is mounted on one side of the top of the frame 1 via a mounting plate 9. A placement frame 4 is connected to the top of the frame 1 via a lifting mechanism 3, and rotating shafts 7 are connected to both sides of the placement frame 4. A gear 8 is connected to one end of each rotating shaft 7, and a heat insulation cover 11 is connected to the outside of the rotating shaft 7. A hydraulic cylinder 6 is mounted in the middle of the top of the frame 1 via a heat insulation box 5, and the output end of the hydraulic cylinder 6 passes through the heat insulation box 5 and is connected to the lifting mechanism 3. A rotating frame 13 is connected to the top of the frame 1 via a support frame 12. The internal structure is connected to a pull rod 14 via two limit wheels 15. A high-temperature resistant mechanical gripper 16 is installed at one end of the pull rod 14. A handle 17 is connected to one side of the support frame 12. Four casters 2 are installed at the bottom of the frame 1, and the four casters are arranged in a rectangular array. When the operator pushes the handle 17, the frame 1 is moved to the designated position by the casters 2, which facilitates the transfer of forgings. The rectangular array of casters 2 makes the frame 1 move more stably.

[0036] See Figures 1-5 In the above embodiment, rack 10 meshes with gear 8. The operator starts hydraulic cylinder 6 through control panel 18. The output end of hydraulic cylinder 6 pushes lifting mechanism 3, causing lifting mechanism 3 to move placement rack 4 upward. During the upward movement of placement rack 4, gear 8 contacts and meshes with rack 10, causing gear 8 to drive rotating shaft 7 to rotate, thereby causing heat insulation cover 11 to rotate 180 degrees, opening heat insulation cover 11 to expose the table surface of placement rack 4, making it convenient for the operator to place forgings on the table surface of placement rack 4. After the operator places the forgings, the output end of hydraulic cylinder 6 pulls lifting mechanism 3, causing lifting mechanism 3 to move placement rack 4 downward back to its original position. At this time, gear 8 contacts and meshes with rack 10 again, causing rotating shaft 7 to reverse and causing heat insulation cover 11 to rotate to cover the table surface of placement rack 4 and forgings, preventing the emitted heat from burning the operator, and at the same time slowing down the cooling rate of forgings, thus achieving a certain heat preservation effect.

[0037] See Figures 1-5, in the above embodiment, both the gear 8 and the rack 10 are made of heat-resistant steel, which has good heat resistance. The gear 8 and the rack 10 made of heat-resistant steel can reduce the influence of the high temperature emitted by the forging, and a high-temperature resistant grease (such as Soco SVKV633) is coated on the outside of the gear 8 and the rack 10 to delay the wear of the gear 8 and the rack 10 and improve the service life.

[0038] Refer to Figures 1-5 , in the above embodiment, the heat insulation cover 11 is rotatably connected to the placement rack 4 through the rotating shaft 7. The heat insulation cover 11 is made of stainless steel and has an aluminum foil reflective layer inside. The placement rack 4 adopts a design of double-layer steel plates sandwiching ceramic fiber, which can significantly improve the heat preservation effect during the transfer of the forging and delay the temperature drop rate.

[0039] Refer to Figures 1-5 , in the above embodiment, the longitudinal section of the pull rod 14 is in the shape of a "middle" character, and the inside of the pull rod 14 is hollow. The staff pushes the pull rod 14 to move the high-temperature resistant mechanical gripper 16 to a suitable position, and operates the empty control panel 18, so that the hydraulic mechanism on the high-temperature resistant mechanical gripper 16 controls the high-temperature resistant mechanical gripper 16 to clamp the high-temperature forging and place it on the placement rack 4. Through the "convex" character setting and cooperation with the limiting wheel 15, the pull rod 14 is limited, so that the pull rod 14 can带动 the high-temperature resistant mechanical gripper 16 to move back and forth to adjust the position of the high-temperature resistant mechanical gripper 16. By extending the distance between the forging and the staff through the pull rod 14, the high temperature of the forging is avoided from affecting the staff. At the same time, the limiting wheel 15 can reduce the frictional resistance when the pull rod 14 moves back and forth. The hollow setting can provide an installation space for the hydraulic mechanism on the high-temperature resistant mechanical gripper 16 and reduce the influence of temperature on the hydraulic mechanism. At the same time, the weight of the pull rod 14 is reduced to achieve light weight, making it more labor-saving when the pull rod 14 slides.

[0040] Refer to Figures 1-5 , in the above embodiment, the limiting wheel 15 is rotatably connected to the rotating frame 13. When the staff lifts or presses the pull rod 14, under the cooperation of the limiting wheel 15 and the rotating rod, the pull rod 14带动 the high-temperature resistant mechanical gripper 16 to rotate along the Z axis to adjust the position of the high-temperature resistant mechanical gripper 16. By adjusting the rotation angle of the high-temperature resistant mechanical gripper 16, the clamping range of the high-temperature resistant mechanical gripper 16 is increased.

[0041] Refer to Figures 1-5 , in the above embodiment, the rotating frame 13 is in the shape of a "Y" character, and the rotating frame 13 is rotatably connected to the support frame 12. While the high-temperature resistant mechanical gripper 16 rotates along the Z axis, through the cooperation of the rotating frame 13 and the support frame 12, the pull rod 14 can also带动 the high-temperature resistant mechanical gripper 16 to rotate along the Y axis to adjust the position of the high-temperature resistant mechanical gripper 16, thereby improving the practicality of the device.

[0042] Refer to Figures 1-5In the above embodiment, a control panel 18 is provided on one side of the top of the pull rod 14, and the hydraulic cylinder 6 and the high-temperature mechanical gripper 16 are electrically connected to the control panel 18. The high-temperature mechanical gripper 16 is the ALH63 / ALH80 two-finger long-stroke heavy-duty gripper from AINTE Technology. The operator starts and operates the high-temperature mechanical gripper 16 and the hydraulic cylinder 6 through the control panel to respectively realize the clamping of the forging and control the lifting and lowering of the placement rack 4, thereby avoiding the heat generated by the high-temperature forging to burn the operator.

[0043] Example 2: To prevent oxidized residue from falling into the tooth grooves of rack 10 or gear 8, Example 2 is an improvement on Example 1. (See attached document.) Figure 5 Protective boxes 19 are installed on both sides of the mounting plate 9, and the rotating shaft 7 is slidably connected to the protective box 19. The gear 8 and the rack 10 are both located inside the protective box 19, and a sliding groove for the rotating shaft 7 to move is opened on one side of the protective box 19. The protective box 19 shields the gear 8 and the rack 10 to prevent the oxide scale formed by oxidation on the outer surface of the forging from falling into the tooth grooves of the gear 8 and the rack 10 during the transfer of the forging, which would affect the meshing of the gear 8 and the rack 10. At the same time, it catches the lubricating oil and prevents the slipping lubricating oil from falling directly to the ground to reduce consumption.

[0044] The implementation principle of this utility model is as follows: The operator pushes handle 17, which, driven by casters 2, pushes the frame 1 to the designated position. The control panel 18 activates hydraulic cylinder 6, whose output pushes lifting mechanism 3, causing the placement rack 4 to move upwards to a certain height. During this upward movement, gear 8 meshes with rack 10, driving shaft 7 to rotate. Shaft 7 then rotates heat insulation cover 11, exposing the surface of the placement rack 4. The operator adjusts the high-temperature resistant mechanical gripper 16 by moving lever 14. Once the forging is in the appropriate position, the high-temperature mechanical gripper 16 is activated. The high-temperature mechanical gripper 16 clamps the forging and transfers it to the platform of the placement rack 4. Then, the hydraulic cylinder 6 is activated. The output end of the hydraulic cylinder 6 pulls the lifting mechanism 3, causing the placement rack 4 to move down and return to its original position. During the downward movement of the placement rack 4, the gear 8 meshes with the rack 10, causing the rotating shaft 7 to reverse. This causes the heat insulation cover 11 to flip and cover the forging, keeping the forging warm and slowing down the cooling rate of the forging. Finally, the handle 17 is pushed to transfer the forging to the forging table.
