Description

Technical Field

[0001] The invention relates to the technical field of workpiece turning over, and in particular to a turning tool and method for a flat workpiece. Background Art

[0002] Flat steel workpieces, such as flanges and reinforcement rings, are common structural parts or semi-finished products in the production process. They are made by cutting and welding steel plates, such as common large discs, reinforcement rings, heads, manhole doors, etc., and are widely used in machinery manufacturing, building structures, shipbuilding and other fields. These workpieces need to be processed on multiple sides during the production process, including welding, cutting, marking and other processes. Flipping is an important step to ensure that all sides of the workpiece can be processed evenly and accurately.

[0003] When flat steel workpieces are produced (including but not limited to welding, cutting, marking and other processes), they are generally placed on a flat ground or other plane for assembly and assembly. After completing the production and processing of splicing, fixing and welding on one side, they need to be turned over, and then the other side is processed and produced. When turning over, it is usually done by manually using a crowbar to tilt it up, and then manually turning it over or clamping it with a lifting clamp. Manual turning over is limited by human strength and physical strength. If the time is too long, the weight is too heavy, or the steel plate is in too close contact with the plane, it will be impossible to turn it over manually. In this case, the industry generally uses a strong magnetic adsorption, tilting one side, padding with iron blocks and other objects to form a gap, and then replacing the self-locking clamp, clamping it and flipping it over. Because it takes some time to replace the strong magnet and clamp, and the flat steel workpiece that stands up after lifting is more dangerous when it falls.

[0030] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those of ordinary skill in the art to which the present invention belongs. In addition, it should also be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0031] As introduced in the background technology, the turning over of flat steel workpieces mainly relies on manual operation, using a crowbar or lifting clamps. This method has problems such as low efficiency, high labor intensity, and low safety. Especially when dealing with workpieces with large weight or special dimensions, manual turning over is not only time-consuming and labor-intensive, but also poses a safety hazard of tipping over and injuring people. In addition, the close contact between the workpiece and the supporting surface also increases the difficulty of turning over. In order to solve the above technical problems, this embodiment proposes a turning tool for flat workpieces.

[0032] Example 1

[0033] like Figure 1 As shown, the turning tool comprises: a base 1, a rotating shaft 2, a turning rod and a sliding limiter 6, wherein the rotating shaft 2 is rotatably mounted on the base 1; the turning rod comprises a main turning rod 5 and an auxiliary turning rod 4, wherein the end of the main turning rod 5 is fixed to the middle of the rotating shaft 2 and is perpendicular to the rotating shaft 2; the auxiliary turning rod 4 is located on both sides of the main turning rod 5 along the axial direction of the rotating shaft 2, and the auxiliary turning rod 4 comprises two vertical rods, wherein the connection of the two rods is fixed to the rotating shaft 2, wherein one of the rods is parallel to the main turning rod 5 (such as Figure 2 As shown in FIG. 5 , the main turning rod 5 is shorter than the main turning rod 5. Figure 3 As shown, the sliding limiter 6 includes a clamping plate 601 and a clamping rod 602 . The clamping plate 601 can be clamped on the main flip bar 5 . The clamping rod 602 is arranged on the clamping plate 601 and has a set distance with the clamping plate 601 .

[0034] A group of 2 50cm long thick steel bars or steel bars are welded on the rotating shaft 2, and another group is welded in a 90-degree rotation direction to form two auxiliary turning rods 4. In the middle position of any group, a long rod (i.e., the main turning rod 5, which can be a tube type with a long stick inserted inside) is welded in the same direction as the steel bars as a booster rod.

[0035] When in use, the force rod is placed horizontally on the ground, and the flat steel workpiece to be turned over is placed on the steel bar near the rotating shaft 2. The force rod is lifted to drive the workpiece to tilt to a maximum of 90 degrees at the vertical balance point, and the turning can be completed by pedaling. The force rod can be improved into a square tube, which passes through a sliding limiter 6 that can be moved up and down and is fastened with screws to fix the workpiece, prevent the workpiece from deflecting, and facilitate the smooth landing after turning over.

[0036] like Figure 1 As shown, the base 1 is an I-shaped base, and the bottom is fixedly connected. The I-shaped base 1 provides basic structural stability. In other embodiments, the base 1 can be a circular plate or a rectangular plate (such as Figure 4As shown in the figure, the base 1 can be adapted to different types of workpieces and workplaces. Alternatively, the base 1 includes a bottom plate, and a support rod is provided on each of the four corners of the bottom plate. The stability is enhanced by adding a bottom plate and a support rod. These structural designs are all intended to improve the versatility and stability of the tooling and adapt to the needs of different working environments.

[0037] The rotating shaft 2 is mounted on the base 1 through a supporting seat 3. Figure 2 As shown, the support seat 3 includes a sleeve 301 and a bearing 302. The sleeve 301 is fixed on both sides of the base 1, the bearing 302 is installed in the sleeve 301, and the shaft 2 is inserted in the bearing 302. Two short round tubes (sleeves 301) with a certain distance are welded on the base 1, the bearing 302 is placed in the round tube, and the shaft 2 is inserted into a hole of the bearing 302. This design allows the shaft 2 to rotate smoothly and stably when turning the workpiece, thereby reducing friction and difficulty of operation, while improving the durability and reliability of the overall tooling.

[0038] The end of the main turning rod 5 away from the rotating shaft 2 is provided with a handle 7, and the handle 7 is a ring-shaped structure. The user can increase the operating torque by holding and operating the handle 7, so as to turn over the workpiece more easily. A ring-shaped structure with a large opening is used, and the size of the ring-shaped structure can be placed in a lifting hook. When a heavy workpiece is turned over, a crane lifting hook can be hooked into the ring structure to lift it, replacing manpower for lifting and turning. The design of the ring-shaped handle 7 not only increases the convenience of operation, but also can realize mechanical assisted turning by cooperating with lifting equipment, further reducing labor intensity and improving the safety of operation.

[0039] The sliding limiter 6 includes two clamping plates 601, which are connected into one body by a butterfly nut group 604. The middle of the clamping plates 601 has an opening, which is sleeved on the main turning rod 5. The clamping plates 601 at the opening position are provided with a locking nut group 605, and the bolts of the locking nut group 605 abut against the main turning rod 5. The fastening strength of the locking nut group 605 is adjusted according to the size of the disc-shaped workpiece, so that the limiter moves up and down, and is used to fix the flat steel workpiece to prevent slipping and deflection.

[0040] Two support blocks 603 are fixed on both sides of the end surface of the clamping plate 601, and a clamping rod 602 is arranged on each support block 603, and the clamping rod 602 is parallel to the main turning rod 5. The function of the clamping rod 602 is to increase the support and limit the workpiece, ensure that the workpiece remains stable during the turning process, and avoid deviation.

[0041] The process of using the tool is as follows: press and rotate the handle 7 to make the main turning rod 5 close to the ground, hoist the flat steel workpiece and place it on the plane formed by the auxiliary turning rod 4 and the main turning rod 5, and adjust the distance of the sliding limiter 6 on the main turning rod 5 by screwing the locking nut group 605, and fix the position of the flat steel workpiece by using the clamping rod 602. Then, lift or hook the handle 7 by manpower or lifting tools to make the auxiliary turning rod 4 and the main turning rod 5 drive the workpiece to rotate around the rotating shaft 2, and when the flat plate is perpendicular to the ground, loosen the locking nut group 605 of the sliding limiter 6 and move it to the tail of the main turning rod 5, the position limit of the flat workpiece is completed, and the vertical workpiece can be lightly pushed by the foot to complete the turning operation.

[0042] Example 2

[0043] For workpieces of larger size or that cannot be directly dumped and dropped, additional improvements are required. The difference between this embodiment and embodiment 1 is that the auxiliary tipping rod 4 is changed. Specifically:

[0044] A turning tool for a flat workpiece comprises: a base 1, a rotating shaft 2, a main turning rod 5 and a turning plate and a sliding limiter 6, wherein the rotating shaft 2 is rotatably mounted on the base 1; the end of the main turning rod 5 is fixed at the middle of the rotating shaft 2 and is perpendicular to the rotating shaft 2.

[0045] The flap includes a first flap 8 and a second flap 9. Figure 5 As shown, the first flap 8 includes a panel, a collar 801 at the bottom of the panel, and an extension rod 803 at the top of the panel. The extension rod 803 is a nut and a screw, which can extend the support length of the flap. The main flap 5 is located at the bottom side of the first flap 8, and the collar 801 of the first flap 8 is fixedly mounted on the rotating shaft 2. Figure 6 As shown, the second flap 9 also includes a board surface, a collar 801 located at the bottom of the board surface, and an extension rod 803 located at the top of the board surface. The collar 801 of the second flap 9 is rotatably mounted on the rotating shaft 2. The sliding limiter 6 includes a clamping plate 601 and a clamping rod 602. The clamping plate 601 can be clamped on the main flap 5. The clamping rod 602 is arranged on the clamping plate 601 and has a set distance from the clamping plate 601. Hooks 802 are arranged on both sides of the board surface of the first flap 8. A hanging ring 901 is arranged on the board surface of the second flap 9. The hook 802 can be hung on the hanging ring 901.

[0046] The first flap 8 of the turning tool is fixedly mounted on the rotating shaft 2, while the second flap 9 is rotatably mounted. A hook 802 is provided on the plate surface of the first flap 8, and a hanging ring 901 is provided on the second flap 9. When turning over a workpiece, the two flaps can be connected together by the cooperation of the hook 802 and the hanging ring 901, so as to clamp the workpiece more stably and prevent it from sliding or falling during the turning process. In addition, it prevents the workpiece from directly tipping over and falling, thereby improving the safety of the turning operation, which is particularly important when handling larger or heavier workpieces. Of course, it is understandable that in another embodiment, the first flap 8 and the second flap 9 can be swapped.

[0047] The turning method of the turning tool is to make the first turning plate 8 close to the ground, place the workpiece on the first turning plate 8, adjust the sliding stopper 6 to clamp on the workpiece, and when turning, rotate the second turning plate 9 to press the second turning plate 9 on the workpiece, hang the hook 802 on the hanging ring 901, rotate the main turning rod 5, drive the first turning plate 8 and the second turning plate 9 to rotate, and complete the turning. This method simplifies the turning process, is more convenient to operate, and always maintains the stability of the workpiece during the whole turning process, protects the workpiece from damage, and reduces the operation risk.

[0048] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
