Description

Technical Field

[0001] This application relates to the field of hot forging auxiliary equipment technology, and in particular to a high-temperature bar stock self-rotating non-damaging transfer device. Background Technology

[0002] Forging processes performed above the metal recrystallization temperature are called hot forging. Hot forging processes have high requirements for the efficiency of high-temperature bar stock transfer and the quality of finished products. In existing technologies, bars heated in an induction furnace are usually manually transferred using manipulator clamps. When clamping bars in a high-temperature softened state, the operator needs to manually adjust their orientation to accommodate the subsequent upsetting process.

[0003] However, this manual transfer method has significant drawbacks. Manually flipping high-temperature bars is inefficient and poses safety hazards such as burns. Moreover, the relevant clamping equipment needs to be equipped with a complex flipping structure to use the clamping arms to flip the high-temperature bars from a horizontal position to a vertical position. For example, CN220560438U discloses a clamping and flipping mechanism and device for bar processing.

[0004] Therefore, it is necessary to study and improve the existing structure to provide a new high-temperature bar stock transfer device, in order to achieve a more practical purpose. Summary of the Invention

[0005] In view of the shortcomings or deficiencies mentioned in the background technology, this application provides a high-temperature bar stock self-rotating non-destructive transfer device. The bar stock can be rotated non-destructively under the action of gravity, realizing the automatic rotation and transfer of high-temperature bar stock, effectively avoiding the risks of manual operation, and improving the yield and safety of the forging process.

[0006] This application provides a high-temperature bar stock self-rotating non-damaging transfer device, comprising:

[0007] A clamping mechanism includes two clamping arms that can move closer to or further away from each other, and clamping blocks are rotatably connected to opposite sides of the two clamping arms. The clamping blocks have a first working position for clamping a workpiece and a second working position for releasing the workpiece.

[0008] The clamping block is configured such that, after clamping the workpiece, it rotates from the first working position to the second working position by relying on the workpiece's own weight; and after releasing the workpiece, it rotates from the second working position back to the first working position by relying on the clamping block's own weight.

[0009] In some embodiments, the two clamping arms are arranged horizontally, the clamping block is parallel to the clamping arms when it is in the first working position, and forms a preset angle with the clamping arms when it is in the second working position.

[0010] In some embodiments, the clamping block is rotatably connected to the clamping arm via a pivot, the axis of which is located directly above the center of gravity of the clamping block.

[0011] In some embodiments, the clamping arm or the clamping block is provided with a first limiting block for limiting the clamping block to a first working position.

[0012] In some embodiments, the clamping arm or the clamping block is provided with a second limiting block for limiting the clamping block to a second working position.

[0013] In some embodiments, the clamping arm and the clamping block are connected by a rotating shaft, and a torsion spring is sleeved on the rotating shaft, with its two ends respectively connected to the clamping arm and the clamping block. The torsion spring is used to keep the clamping block in a first working position.

[0014] In some embodiments, the workpiece is a bar stock, and the clamping block is provided with an arc-shaped clamping surface that matches the shape of the bar stock.

[0015] In some embodiments, the mass distribution of the clamping block in the vertical direction is uneven, with the lower half being heavier than the upper half; in the horizontal direction, the mass distribution of the clamping block on the left and right sides is symmetrical.

[0016] In some embodiments, a thrust bearing is installed between the clamping arm and the clamping block, and a high-temperature resistant coating is provided on the clamping surface of the clamping block.

[0017] In some embodiments, one end of the clamping block is threaded with a counterweight screw, and the length of the counterweight screw extending out of the clamping block is adjusted to keep the clamping block balanced in the first working position.

[0018] The beneficial effects of the technical solution provided in this application include:

[0019] This application provides a high-temperature bar stock self-rotating non-damaging transfer device. Due to the clamping mechanism, it includes two clamping arms that can move closer or further apart from each other. The opposite sides of the two clamping arms are respectively rotatably connected to clamping blocks. The clamping blocks have a first working position for clamping the workpiece and a second working position for releasing the workpiece. The clamping blocks are configured such that: after clamping the workpiece, they rotate from the first working position to the second working position by relying on the weight of the workpiece; after releasing the workpiece, they rotate from the second working position back to the first working position by relying on the weight of the clamping blocks.

[0020] Therefore, the clamping and release of the bar stock can be achieved through two openable clamping arms. The clamping arms are rotatably connected to clamping blocks. Under the action of gravity, the clamping blocks can automatically rotate and switch between the first working position and the second working position. Before clamping, the clamping blocks are parallel to the clamping arms. After clamping the bar stock, under the action of the bar stock's gravity, the clamping blocks flip upward relative to the clamping arms, so that the bar stock can be flipped without damage. This realizes the automatic flipping and transfer of high-temperature bar stock, effectively avoiding the risks of manual operation and improving the yield and safety of the forging process.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] In view of the shortcomings or deficiencies mentioned in the background technology, this application provides a high-temperature bar stock self-rotating non-destructive transfer device. The bar stock can be rotated non-destructively under the action of gravity, realizing the automatic rotation and transfer of high-temperature bar stock, effectively avoiding the risks of manual operation, and improving the yield and safety of the forging process.

[0033] See Figures 1 to 7 As shown in the figure, this application provides a high-temperature bar stock self-rotating non-damaging transfer device, including:

[0034] The clamping mechanism includes two clamping arms 1 that can move closer to or further away from each other. The opposite sides of the two clamping arms 1 are respectively rotatably connected to clamping blocks 2. The clamping blocks 2 have a first working position for clamping the workpiece and a second working position for releasing the workpiece.

[0035] The clamping block 2 is configured such that after clamping the workpiece, it rotates from the first working position to the second working position by relying on the weight of the workpiece; after releasing the workpiece, it rotates from the second working position back to the first working position by relying on the weight of the clamping block 2.

[0036] The high-temperature bar stock self-rotating non-damaging transfer device of this application embodiment can clamp and release the bar stock 7 by setting two openable clamping arms 1. The clamping arms 1 are rotatably connected to the clamping blocks 2. Under the action of gravity, the clamping blocks 2 can automatically rotate and switch between the first working position and the second working position. Before clamping, the clamping blocks 2 are parallel to the clamping arms 1, which facilitates horizontal clamping of the bar stock 7. After clamping the bar stock 7, under the action of gravity of the bar stock 7, the clamping blocks 2 rotate upward relative to the clamping arms 1, so that the bar stock 7 completes non-damaging rotation, thereby realizing the automatic rotation and transfer of high-temperature bar stock, effectively avoiding the risks of manual operation, and improving the yield and safety of the forging process.

[0037] For example, the clamping block 2 is rotatably connected to the clamping arm 1 via the rotating shaft 3. By reasonably setting the rotation center of the clamping block 2, the mass of the upper part of the clamping block 2 at the rotation center is less than the mass of the lower part. At the same time, the mass of the left and right parts at the rotation center is the same and symmetrically arranged. Thus, the clamping block 2 can achieve self-weight balance in the first working position, so that the clamping block 2 is parallel to the clamping arm 1, which is convenient for horizontal clamping of the bar stock 7. When the front end of the clamping block 2 clamps the bar stock 7, the balance state of the clamping block 2 is broken. Under the action of the gravity of the bar stock 7, the end of the clamping block 2 away from the bar stock 7 flips upward relative to the clamping arm 1, so that the bar stock 7 automatically flips from the horizontal state to the vertical state. Thus, the bar stock 7 can be directly released for subsequent processing without flipping the clamping arm 1, which can realize the automatic flipping and transfer of high temperature bar stock.

[0038] In other embodiments, the mass of the left side of the clamping block 2 at the rotation center can be greater than the mass of the right side, and a stop block is welded to the top surface of the left side of the clamping block 2. Since the mass of the left side of the clamping block 2 is greater than the mass of the right side, when the left side flips to the first working position under the action of gravity, the stop block abuts against the top of the clamping arm 1 to keep the clamping block 2 in the first working position. Then, the right side of the clamping block 2 is used to clamp the bar stock 7. After clamping the bar stock 7, the balance state of the clamping block 2 is broken. Under the action of gravity of the bar stock 7, the bar stock 7 drives the clamping block 2 to flip downward relative to the clamping arm 1, so that the bar stock 7 automatically flips from the horizontal state to the vertical state, realizing the automatic flipping and transfer of the high-temperature bar stock.

[0039] In some alternative embodiments: see Figures 1 to 7 As shown in the figure, this application provides a high-temperature bar stock self-rotating non-damaging transfer device. The two clamping arms 1 of the high-temperature bar stock self-rotating non-damaging transfer device are arranged horizontally. When the clamping block 2 is in the first working position, it is parallel to the clamping arm 1. When the clamping block 2 is in the second working position, it forms a preset angle with the clamping arm 1.

[0040] In this embodiment, the clamping arm 1 is set horizontally and the clamping block 2 is parallel to the clamping arm 1, so that the external driving device can drive the clamping arm 1 and the clamping block 2 to clamp the bar 7 facing the direction. After the clamping block 2 clamps the bar 7, under the action of the weight of the bar 7, the clamping block 2 flips forward to the vertical position and forms a preset angle with the clamping arm 1, so that the bar 7 automatically flips from the horizontal state to the vertical state.

[0041] For example, the preset included angle is set to 90 degrees or close to 90 degrees. For instance, the preset included angle can be 85 degrees. By welding a stop block to the clamping arm 1, the angle at which the clamping block 2 can be flipped forward is limited to 85 degrees, which does not affect the release of the bar stock 7. At the same time, after the bar stock 7 is released, it is convenient for the clamping block 2 to flip backward and reset.

[0042] It should be noted that the clamping block 2 switches between parallel and vertical states under the action of gravity, making the mechanical path of the clamping and flipping actions more in line with the transfer requirements of high-temperature bar stock, while achieving stability after flipping to the preset clamping angle.

[0043] In some alternative embodiments: see Figures 1 to 3 As shown in the figure, this application embodiment provides a high-temperature bar stock self-rotating non-damaging transfer device. The clamping block 2 of the high-temperature bar stock self-rotating non-damaging transfer device is rotatably connected to the clamping arm 1 through the rotating shaft 3. The axis of the rotating shaft 3 is located directly above the center of gravity of the clamping block 2.

[0044] In this embodiment, by placing the rotating shaft 3 directly above the center of gravity of the clamping block 2, the clamping block 2 automatically switches angles using the principle of gravitational torque, ensuring smooth clamping and releasing actions. Specifically, when the clamping block 2 is not clamping the bar stock 7, it can achieve self-balancing under its own weight, causing its center of gravity to return to directly below the rotating shaft 3, thus keeping the clamping block 2 in the first working position, parallel to the horizontally positioned clamping arm 1.

[0045] For example, in this embodiment, the clamping block 2 is a rectangular block with uniform mass. The large rectangular surface away from the clamping arm 1 serves as the clamping surface and is provided with an arc surface that matches the bar stock 7. The rotating shaft 3 is rotatably connected to the clamping block 2. The axis of the rotating shaft 3 is located directly above the intersection of the diagonals of the large rectangular surface of the rectangular block, so that the mass of the clamping block 2 at the upper part of the axis is less than the mass at the lower part. At the same time, the mass of the left and right parts of the axis is the same and the shape is symmetrically arranged. Thus, the clamping block 2 can be balanced by its own weight in the first working position, so that the clamping block 2 is parallel to the clamping arm 1, which is convenient for horizontally clamping the bar stock 7.

[0046] When the front end of the clamping block 2 clamps the bar stock 7, the balance of the clamping block 2 is broken. Under the gravity of the bar stock 7, the end of the clamping block 2 away from the bar stock 7 flips upward relative to the clamping arm 1, so that the bar stock 7 automatically flips from the horizontal state to the vertical state. Thus, the bar stock 7 can be directly released for subsequent processing without flipping the clamping arm 1, and the automatic flipping and transfer of high-temperature bar stock can be realized.

[0047] In some alternative embodiments: see Figures 1 to 7 As shown in the figure, this application provides a high-temperature bar stock self-rotating non-damaging transfer device. The clamping arm 1 or clamping block 2 of the high-temperature bar stock self-rotating non-damaging transfer device is provided with a first limiting block 4 for limiting the clamping block 2 to a first working position.

[0048] In this embodiment, the clamping block 2 is restricted to the first working position by the first limiting block 4, which makes it convenient for the clamping block 2 to clamp the bar material 7 and can prevent clamping failure caused by accidental disturbance during the clamping process.

[0049] For details, see Figure 4As shown, the clamping arm 1 is horizontally arranged, the clamping block 2 is parallel to the clamping arm 1, the clamping block 2 is in the first working position, and the bottom surface of the clamping arm 1 is fixedly connected to the first limiting block 4 extending to the bottom surface of the clamping block 2. The first limiting block 4 can prevent the other end of the clamping block 2 from flipping upward, so that the clamping block 2 can stably clamp the bar 7 in the first working position.

[0050] In another embodiment, see Figure 5 As shown, the clamping arm 1 is horizontally positioned, and the clamping block 2 is parallel to the clamping arm 1. The clamping block 2 is in the first working position. A first limiting block 4 extending to the top surface of the clamping arm 1 is fixedly connected to the top surface of the clamping block 2. The first limiting block 4 can prevent the other end of the clamping block 2 from flipping upwards, making it easier for the clamping block 2 to stably clamp the bar stock 7 in the first working position. In some other embodiments, the first limiting block 4 can be fixedly connected to the bottom surface of the clamping arm 1 and the top surface of the clamping block 2 respectively, improving the stability of the clamping block 2 in the first working position.

[0051] In some alternative embodiments: see Figures 1 to 7 As shown in the embodiment of this application, a high-temperature bar stock self-rotating non-damaging transfer device is provided. The clamping arm 1 or clamping block 2 of the high-temperature bar stock self-rotating non-damaging transfer device is provided with a second limiting block 5 for limiting the clamping block 2 to a second working position.

[0052] In this embodiment, the clamping block 2 is restricted to the position where the bar stock 7 is released by the second limiting block 5, which makes it easy for the clamping block 2 to quickly flip and stay in the second working position. This can prevent the bar stock 7 from swinging repeatedly in the second working position and improve the efficiency and reliability of the self-flipping transfer of the bar stock 7.

[0053] For details, see Figure 5 As shown, the clamping arm 1 is horizontally positioned, and the clamping block 2 is perpendicular to the clamping arm 1. The clamping block 2 is in the second working position. A second limiting block 5 extending to the right side of the clamping block 2 is fixedly connected to the top surface of the clamping arm 1. The second limiting block 5 can prevent the upper end of the clamping block 2 from continuing to flip downward due to inertia, so that the clamping block 2 can be stabilized in the second working position to release the bar stock 7, while not affecting the clamping block 2 to flip and reset to the first working position.

[0054] In another embodiment, see Figure 5 As shown, the clamping arm 1 is horizontally positioned, and the clamping block 2 is perpendicular to the clamping arm 1. The clamping block 2 is in the second working position. A second limiting block 5 extending to the top surface of the clamping arm 1 is fixedly connected to the right side of the clamping block 2. The second limiting block 5 can prevent the upper end of the clamping block 2 from continuing to flip downward due to inertia, so that the clamping block 2 can be stabilized in the second working position to release the bar stock 7, while not affecting the clamping block 2 to flip back to the first working position. In this embodiment, after the clamping block 2 flips to the horizontal position, the second limiting block 5 can also abut against the top surface of the clamping arm 1 again to limit the clamping block 2 to the first working position.

[0055] In some alternative embodiments: see Figures 1 to 7 As shown, this application embodiment provides a high-temperature bar stock self-rotating non-damaging transfer device. The clamping arm 1 and the clamping block 2 of the high-temperature bar stock self-rotating non-damaging transfer device are connected by a rotating shaft 3. A torsion spring is sleeved on the rotating shaft 3, with its two ends respectively connected to the clamping arm 1 and the clamping block 2. The torsion spring is used to keep the clamping block 2 in a first working position.

[0056] In this embodiment, a torsion spring provides a reset torque, ensuring that the clamping block 2 remains stably in the first position before clamping the bar stock 7. This reduces the shaking of the clamping block 2 caused by clamping operations or equipment vibrations, and improves the reliability and stability of the bar stock clamping operation.

[0057] For example, the clamping block 2 has a mounting hole, one end of the rotating shaft 3 is fixedly connected to the clamping arm 1, and the other end extends into the mounting hole. The torsion spring is fitted on the rotating shaft 3 and located in the mounting hole. One end of the torsion spring is fixedly connected to the clamping block 2, and the other end is fixedly connected to the clamping arm 1. A bearing is installed between the rotating shaft 3 and the clamping block 2 to realize the rotation of the clamping block 2 relative to the rotating shaft 3. The elastic force of the torsion spring can make the clamping block 2 balanced in the first working position.

[0058] After the clamping block 2 clamps the bar stock 7, the bar stock 7 can overcome the torsion spring force under the action of gravity, causing the clamping block 2 to flip to the second working position. It should be noted that the torsion spring in this embodiment is made of high temperature resistant material, and the torsion spring is not shown in the figure.

[0059] In some alternative embodiments: see Figures 1 to 7 As shown in the figure, this application provides a high-temperature bar stock self-rotating non-damaging transfer device. The workpiece of the high-temperature bar stock self-rotating non-damaging transfer device is a bar stock 7, and the clamping block 2 is provided with an arc-shaped clamping surface that matches the shape of the bar stock 7.

[0060] This embodiment of the application utilizes an arc-shaped clamping surface that conforms to the cylindrical contour of the bar stock 7, dispersing the clamping pressure and significantly reducing the probability of surface indentations. Specifically, in this embodiment, the clamping block 2 is a rectangular block with uniform mass. The large rectangular surface on the side away from the clamping arm 1 serves as the clamping surface and is provided with an arc surface that matches the bar stock 7. The rotating shaft 3 is rotatably connected to the clamping block 2, and the axis of the rotating shaft 3 is located directly above the center of gravity of the rectangular block, allowing the rectangular block to be balanced in a horizontal position by its own weight.

[0061] In some alternative embodiments: see Figures 1 to 7 As shown in the embodiment of this application, a high-temperature bar stock self-rotating non-damaging transfer device is provided. The clamping block 2 of the high-temperature bar stock self-rotating non-damaging transfer device has an uneven mass distribution in the vertical direction, with the lower half of the mass being heavier than the upper half; in the horizontal direction, the mass distribution of the left and right sides of the clamping block 2 is symmetrically arranged.

[0062] This embodiment optimizes the gravity-driven characteristics of the clamping block 2 through mass distribution design, enabling the clamping block 2 to maintain natural balance in both clamping and releasing states, thereby improving the reliability of the device. For example, the clamping block 2 in this embodiment is rectangular in shape and has an uneven mass distribution; specifically, the upper part is lighter than the lower part, while the left and right parts have the same mass and shape. Therefore, when the center of the clamping block 2 is rotatably connected to the clamping arm 1, it can maintain a horizontal position through its own weight; after clamping the bar 7, it can automatically flip to a vertical position along with the bar 7.

[0063] In some alternative embodiments: see Figures 1 to 7 As shown in the figure, this application provides a high-temperature bar stock self-rotating non-damaging transfer device. A thrust bearing is installed between the clamping arm 1 and the clamping block 2 of the high-temperature bar stock self-rotating non-damaging transfer device, and a high-temperature resistant coating is provided on the clamping surface of the clamping block 2.

[0064] In this embodiment, by setting a thrust bearing, the clamping arm 1 and the clamping block 2 can be spaced apart, preventing frictional wear between the clamping arm 1 and the clamping block 2 and extending the service life of the device; the high-temperature resistant coating can effectively prevent workpiece damage caused by high-temperature oxidation or adhesion of the clamping surface.

[0065] For example, the clamping block 2 and the clamping arm 1 are rotatably connected by the rotating shaft 3. An installation groove can be opened on the side of the clamping block 2 opposite to the clamping arm 1. A pressure bearing coaxially arranged with the rotating shaft 3 is installed in the installation groove. The clamping block 2 and the clamping arm 1 axially abut against the pressure bearing, so that a certain gap is maintained between the clamping block 2 and the clamping arm 1. When clamping the bar 7, the axial extrusion force is transmitted to the pressure bearing, which can avoid friction between the clamping block 2 and the clamping arm 1.

[0066] In some alternative embodiments: see Figures 1 to 7 As shown in the embodiment of this application, a high-temperature bar stock self-rotating non-damaging transfer device is provided. One end of the clamping block 2 of the high-temperature bar stock self-rotating non-damaging transfer device is threadedly connected to a counterweight screw 6. By adjusting the length of the counterweight screw 6 extending out of the clamping block 2, the clamping block 2 is kept balanced in the first working position.

[0067] This embodiment of the application utilizes the adjustable design of the counterweight screw 6 to match the gravitational torque at the clamping end of the clamping block 2, thereby achieving balance adjustment of the clamping block 2 in a horizontal position. Specifically, when the end of the clamping block 2 furthest from the counterweight screw 6 wears down due to long-term clamping of the bar stock 7, causing the clamping block 2 to lose balance in the first position, the other end of the counterweight screw 6 can be rotated to adjust its extension length, balancing the gravitational torque on that side with the other side, thus stabilizing the clamping block 2 in a horizontal position.
