Description

Technical Field

[0001] This utility model relates to the field of molybdenum product manufacturing technology, and in particular to a molybdenum billet flipping and handling device. Background Technology

[0002] Molybdenum and its alloys are widely used in metallurgy, electronics, aerospace, and nuclear industries due to their high melting point, high strength, good thermal and electrical conductivity, and corrosion resistance. As a basic raw material for deep processing, molybdenum billets often require flipping (e.g., changing their orientation, inspecting different surfaces, or loading them into different workstations) and handling operations during their production, storage, and subsequent processing.

[0003] Existing mechanized handling equipment (such as overhead cranes, forklifts, and ordinary conveyor lines) can typically only perform horizontal handling or simple lifting, making it difficult to achieve precise flipping movements and seamlessly connect with subsequent handling or workstations. This results in molybdenum billets needing to be transferred and positioned multiple times between different pieces of equipment, increasing production cycle time and the probability of errors.

[0004] Therefore, there is an urgent need to develop a device that is relatively simple in structure, safe and reliable in operation, and can effectively achieve the integrated stable flipping and handling of molybdenum billets. To this end, we designed a molybdenum billet flipping and handling device. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model discloses a molybdenum billet flipping and handling device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A molybdenum billet flipping and conveying device includes:

[0008] The first U-shaped frame has a first flipping frame rotatably connected to the outer sides of both open ends, and the rotation center axes of the two first flipping frames are collinear; a first driving component is installed on the first U-shaped frame to drive the first flipping frame to flip, so that the first flipping frame receives and carries the molybdenum billet to flip.

[0009] The second U-shaped frame has two rotatably connected second flipping frames on the inner sides of its open ends, and the rotation center axes of the two second flipping frames are collinear; a second driving component is installed on the inner side of the second U-shaped frame to drive the second flipping frame to flip, so that the second flipping frame receives the molybdenum billet on the first flipping frame and carries the molybdenum billet to flip.

[0010] The two second flipping frames are located on the outer sides of the two first flipping frames, respectively.

[0011] Furthermore, a long shaft is rotatably connected to the open end of the first U-shaped frame, and the two ends of the long shaft are respectively fixedly connected to the first flipping frame on the same side;

[0012] The long shaft drive is connected to the first drive component, and drives the two first flipping frames to flip synchronously through the long shaft.

[0013] Furthermore, both ends of the opening of the second U-shaped frame are rotatably connected to short shafts, and the inner ends of the short shafts are fixedly connected to the second flipping frame on the same side.

[0014] The bottom of the second U-shaped frame is rotatably connected to a drive shaft, and the two ends of the drive shaft are respectively connected to a short shaft on the same side.

[0015] The drive shaft is connected to the second drive component, and drives the two short shafts to rotate synchronously, thereby causing the two second tilting frames to tilt synchronously.

[0016] Furthermore, the first and / or second tilting frame includes a main beam, which is rotatably connected to the corresponding U-shaped frame; a support beam perpendicular to the tilting direction is provided on one side of the main beam.

[0017] Furthermore, the main beam is provided with a groove along its length, and a slider is slidably installed in the groove; the inner end of the support beam is installed on the slider;

[0018] The main beam is also equipped with an adjusting screw that drives the slider to move along the slide groove.

[0019] Furthermore, the main beam is rotatably connected to a corresponding U-shaped frame at its center; two support beams are installed on the main beam, and the two support beams are arranged symmetrically along the rotational center axis of the main beam.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. Through the coordinated design of the first and second flipping frames, the entire process of receiving, flipping, stable handover, secondary flipping, and preparing for transport of molybdenum billets can be completed continuously on a single device. This completely eliminates the cumbersome steps of multiple transfers and positioning on different equipment in the traditional method, significantly shortening the production cycle and greatly improving production efficiency.

[0022] 2. The first flipping frame is directly driven by a single first drive component through a coaxial long shaft, ensuring that the two first flipping frames flip strictly synchronously; the second flipping frame is driven by a single second drive component through a short shaft-transmission shaft synchronous transmission mechanism, similarly ensuring that the two second flipping frames flip strictly synchronously, thus solving the problem of molybdenum billet displacement, twisting or even overturning caused by asynchrony in multi-point support flipping.

[0023] 3. The spatial layout design of the second flipping frame located within the first flipping frame creates an interference-free physical channel for the transfer of molybdenum billets from the first flipping frame to the second flipping frame, achieving seamless and smooth connection between processes and avoiding the risk of jamming or falling during the handover process;

[0024] 4. The overall device is based on the frame structure of the first U-shaped frame and the second U-shaped frame, combined with the modular flipping frame, which has a clear and compact structure and is easy to manufacture and maintain. Attached Figure Description

[0031] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

It should be understood that if terms such as "end", "side", "end portion", "side part", "lateral", "longitudinal", etc. indicate orientation or positional relationship, they are only corresponding to the length and width of the corresponding component.

[0032] Example 1, in conjunction with Appendix Figure 1-4 A molybdenum billet flipping and handling device is mainly used for stably receiving, precisely flipping, reliably transferring, and secondarily flipping and handling heavy molybdenum billets from a first position to a second position. The device includes:

[0033] The first flipping unit is used to receive the initial flip from the first position, specifically as follows:

[0034] The first U-shaped frame 1, as the basic support frame, has its open end facing vertically.

[0035] There are two first tilting frames 2, and they are identical in structure. Each first tilting frame 2 is rotatably connected to the outside of the open end of the first U-shaped frame 1 via one end of its main beam 7. Specifically, a long shaft 11 is rotatably connected to the open end of the first U-shaped frame 1. The two ends of the long shaft 11 are respectively fixedly connected to the main beam 7 of the first tilting frame 2 on the same side. This structure ensures that the rotation center axes of the two first tilting frames 2 are collinear and operate synchronously.

[0036] The first drive unit 3, preferably a servo motor, is fixedly mounted on the first U-shaped frame 1. Its output end (e.g., via a coupling, gear, or sprocket chain) drives the long shaft 11. When the first drive unit 3 is started, it synchronously drives the two first tilting frames 2 to tilt precisely around their collinear rotation center axis via the long shaft 11.

[0037] The second flipping unit is used to receive and flip the molybdenum billet a second time and transport it to the second position. Specifically:

[0038] The second U-shaped frame 4 has a similar structure to the first U-shaped frame 1, but its spatial position is corresponding, and its open end is also set vertically.

[0039] There are two second tilting frames 5, and they are identical in structure. Each second tilting frame 5 is rotatably connected to the inner side of both ends of the open end of the second U-shaped frame 4 via one end of its main beam 7. Specifically, a short shaft 41 is rotatably connected to each end of the open end of the second U-shaped frame 4. The inner end of each short shaft 41 is fixedly connected to the main beam 7 of the second tilting frame 5 on the same side, pointing towards the inner side of the U-shaped frame.

[0040] The synchronous transmission mechanism has a drive shaft 42 rotatably connected to the bottom of the second U-shaped frame 4. The two ends of the drive shaft 42 are respectively connected to the short shaft 41 on the same side through a chain mechanism or a synchronous belt pulley mechanism.

[0041] The second drive unit 6, preferably a servo motor, is fixedly mounted on the second U-shaped frame 4. Its output end (e.g., via gears or sprockets and chains) drives the transmission shaft 42. When the second drive unit 6 is started, it synchronously drives the two short shafts 41 to rotate in the same direction and at the same speed through the transmission shaft 42 and the synchronous transmission mechanism, thereby causing the two second tilting frames 5 to tilt around their collinear rotation center axis.

[0042] Among them, the two second flipping frames 5 are respectively located on the outer sides of the two first flipping frames 2, facing away from each other. That is, in the attached Figure 3In this configuration, the first flipping frame 2 is located on the inner side near the center, while the second flipping frame 5 is located on its outer side. This arrangement provides a spatial channel for the smooth transfer of the molybdenum billet from the first flipping frame 2 to the second flipping frame 5, avoiding structural interference.

[0043] The flipping frame structure is applicable to both the first and second flipping frames, specifically as follows:

[0044] Main beam 7: This is the main load-bearing structure of the tilting frame, typically a long, rigid beam such as square steel or I-beam. One end of it is connected to the long axis 11 or short axis 41 on the corresponding U-shaped frame.

[0045] Support beam 8 is used to directly support the molybdenum billet. The inner end of support beam 8 (the end closest to the main beam) is fixedly installed on the main beam 7.

[0046] Combined with appendix Figure 5 Workflow:

[0047] See attached document Figure 5 In step a, the first flipping frame 2 is in a vertical position (e.g., -90°); the second flipping frame 5 is in a vertical position (e.g., 90°), waiting to be received;

[0048] See attached document Figure 5 In step b, the first driving component 3 is activated to drive the long shaft 11 to rotate, causing the two first flipping frames 2 to rotate 90° clockwise synchronously and receive the molybdenum billet A; refer to the attached diagram. Figure 5 In step c, the first flipping frame 2 continues to rotate 90° clockwise, so that the molybdenum billet A is lifted and flipped to a vertical state; at this time, the molybdenum billet A on the first flipping frame 2 is exactly in a position that can be supported by the second flipping frame 5, that is, the support beam 8 of the second flipping frame 5 is located below the molybdenum billet A.

[0049] See attached document Figure 5 In step d, the second drive unit 6 is activated to drive the transmission shaft 42 to rotate, which in turn drives the two short shafts 41 to rotate synchronously through the synchronous transmission mechanism. This, in turn, drives the two second flipping frames 5 to rotate 90° clockwise synchronously, so that the molybdenum billet A is flipped to a horizontal position. At this time, the molybdenum billet A on the second flipping frame 5 is in a position that is convenient for subsequent handling or loading into the target station; refer to the appendix. Figure 5 Then, the second flipping frame 5 rotates 270° clockwise back to its initial state, placing the molybdenum billet A in the position for subsequent handling or loading into the target station; the first flipping frame 2 continues to rotate 180° back to its initial state, waiting for the next work cycle.

[0050] Example 2, in conjunction with Appendix Figure 4 A molybdenum billet flipping and handling device is described. However, in Embodiment 1, the support beam 8 of the flipping frame is fixed in position, making it difficult to adapt to flipping and handling operations of molybdenum billets of different widths. This embodiment differs from Embodiment 1 in that:

[0051] The main beam 7 has a groove 71 along its length.

[0052] The slider 72 is slidably mounted in the slide groove 71.

[0053] The adjusting screw 73 is arranged parallel to the slide groove 71, with one end extending to the end of the main beam 7 and equipped with a handwheel or can be driven by a tool. The adjusting screw 73 has a threaded section that is threadedly engaged with the slider 72. That is, rotating the adjusting screw 73 allows the slider 72 to move along the slide groove 71, thereby adjusting the position of the support beam 8 to accommodate molybdenum billets of different widths.

[0054] Example 3, in conjunction with Appendix Figure 1-4 A molybdenum billet flipping and handling device is described. Since in Embodiment 1, both the first flipping frame 2 and the second flipping frame 5 need to be flipped 360° for each operation, this embodiment optimizes upon Embodiment 1.

[0055] The first tilting frame 2 is rotatably connected to the outer sides of both ends of the opening of the first U-shaped frame 1 via the middle of its main beam 7.

[0056] The second tilting frame 5 is rotatably connected to the inner sides of both ends of the opening of the second U-shaped frame 4 via the middle of its main beam 7.

[0057] Two support beams 8 are installed on the main beam 7, and the two support beams 8 are arranged symmetrically along the rotation center axis of the main beam 7.

[0058] Workflow:

[0059] See attached document Figure 5 In step a, the first flipping frame 2 is in a vertical position (e.g., -90°); the second flipping frame 5 is in a vertical position (e.g., 90°), waiting to be received;

[0060] See attached document Figure 5 In step b, the first driving component 3 is activated to drive the long shaft 11 to rotate, causing the two first flipping frames 2 to rotate 90° clockwise synchronously and receive the molybdenum billet A; refer to the attached diagram. Figure 5 In step c, the first flipping frame 2 continues to rotate 90° clockwise, so that the molybdenum billet A is lifted and flipped to a vertical state, waiting for the next working cycle; at this time, the molybdenum billet A on the first flipping frame 2 is exactly in a position that can be supported by the second flipping frame 5, that is, the support beam 8 of the second flipping frame 5 is located below the molybdenum billet A.

[0061] See attached document Figure 5 In step d, the second drive unit 6 is activated to drive the transmission shaft 42 to rotate, which in turn drives the two short shafts 41 to rotate synchronously through the synchronous transmission mechanism. This, in turn, drives the two second flipping frames 5 to rotate 90° clockwise synchronously, so that the molybdenum billet A is flipped to a horizontal position. At this time, the molybdenum billet A on the second flipping frame 5 is in a position that is convenient for subsequent handling or loading into the target station; refer to the appendix. Figure 5Then, the second flipping frame 5 rotates 90° clockwise again, placing the molybdenum billet A in the position for subsequent handling or loading into the target station, waiting for the next work cycle.
