[0001] This utility model belongs to the field of mechanical parts processing technology, and more specifically, it relates to a heavy-duty rectangular blank flipping clamp for blanking. Background Technology

[0002] Machining large parts is a complex manufacturing process involving multiple technologies and equipment. Large parts generally refer to mechanical parts with significant dimensions. While there are no strict limits to their size, parts exceeding several meters in length, width, or height, or weighing several tons, can generally be considered large parts. Examples include propellers for large ships and rotors for large generator sets. Machining large parts typically employs various technologies, such as cutting, forging, machining, and welding, and utilizes equipment such as large lathes, large milling machines, and large boring machines.

[0003] Positioning the blanks during the machining of large parts is quite difficult. The existing method for positioning cuboid blanks is to use a positioning mold. The size of the mold is consistent with the blank that needs to be positioned, so the blank is held in place by the mold. This positioning method can usually only be adapted to blanks of a single size. In order to adapt to cuboid blanks of more sizes, the existing positioning structure needs to be improved.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a heavy-duty rectangular billet turning and clamping frame for billet opening, in order to achieve a more practical purpose. Summary of the Invention

[0029] As shown in the accompanying Figure 1 to the accompanying Figure 4 As shown:

[0030] The utility model provides a kind of heavy cuboid blank turnover clamping frame for blooming, comprising:

[0031] Two groups of clamping mechanisms, the clamping mechanism can clamp cuboid blank 20 and drive it to rotate;

[0032] The clamping mechanism comprises a bracket 11, a ring body 111 fixedly connected to the bracket 11, four through holes 110 arranged in the circumferential direction of the axial direction of the ring body 111, a guide rod 12 slidingly arranged in the through holes 110, an abutting plate 121 arranged at the inner end of the guide rod 12, and a wear-resistant ball head 122 arranged at the outer end of the guide rod 12.

[0033] The guide rod 12 is connected with a rebounding piece, the bracket 11 is provided with a power unit 15, and the power unit 15 can drive the guide rod 12 to move in the axial direction of the through hole 110.

[0034] The utility model discloses a plurality of clamping mechanisms are set up to the cuboid blank 20 clamping positioning, its guide rod 12 in the through hole 110 sliding, and the guide rod 12 is driven to move inwards by the power unit 15, so that the guide rod 12 inner end abuts the cuboid blank 20, to push it to the appropriate position, thereby realizing the positioning of the cuboid blank 20. The wear-resistant ball head 122 is made of high manganese steel. During processing, the cutting head is located directly above the upper surface of the cuboid blank 20, thereby realizing the processing of the surface.

[0035] The utility model discloses be especially suitable for the part of the length section of cuboid blank 20 being square.

[0036] The power unit 15 comprises a gear ring 151 rotatably connected with the ring body 111, a driving gear 152 engaged with the gear ring 151, and a motor 153 fixedly connected to the ring body 111, a plurality of wedge-shaped blocks 1510 are arranged in the circumferential direction on the inner side of the gear ring 151, and the number of the wedge-shaped blocks 1510 is consistent with and corresponds to the guide rod 12. The wedge-shaped blocks 1510 exert radial pressure on the guide rod 12 during rotation, thereby driving the guide rod 12 to clamp the outer surface of the cuboid blank 20.

[0037] It also comprises a dust cover 16, and the dust cover 16 covers the gear ring 151 and the driving gear 152. The dust cover 16 is arranged to prevent debris generated during the processing of the cuboid blank 20 from flying into the gap between the gear ring 151 and the driving gear 152, thereby preventing the equipment from malfunctioning.

[0040] The lifting device 19 is a hydraulic cylinder. The hydraulic cylinder can adapt to the vertical lifting of heavy parts. Because the hydraulic oil is almost incompressible, under the same cylinder diameter and pressure, the hydraulic cylinder can output much larger force than the air cylinder. The viscosity of the hydraulic oil can effectively reduce vibration and impact during movement, effectively reducing the shaking of the heavy parts.

[0041] The specific use mode and role of the embodiment are as follows:

[0042] In use, the cuboid blank 20 is hoisted to the roller shaft 18 at one end, and the cuboid blank 20 is pushed to move to the other side until the two ends of the cuboid blank 20 are located inside the two groups of clamping mechanisms respectively, then the motor 153 is started to drive the driving gear 152 to rotate, the driving gear 152 drives the gear ring 151 to rotate, so that the wedge-shaped block 1510 in the gear ring 151 rotates, thereby exerting an inward force on the wear-resistant ball head 122 at the inner end of the guide rod 12, and the abutting plate 121 of the guide rod 12 clamps and positions the cuboid blank 20. When it is necessary to turn over the cuboid blank 20, the motor 153 is reversely rotated to make the wedge-shaped block 1510 reversely rotate, so that the guide rod 12 moves under the elastic force of the spring 13, thereby turning over the cuboid blank 20, and the machining of the remaining surface is realized.

[0043] The remaining features are the same as those of the first embodiment, and the difference is that the embodiment further comprises a roller support frame, the roller support frame comprises a wheel frame 17, a plurality of roller shafts 18 rotationally connected with the wheel frame 17, and a plurality of lifting devices 19 arranged at the bottom of the wheel frame 17, and the lifting device 19 can drive the wheel frame 17 to move up and down.

[0044] In order to reduce the driving load of the power unit 15 in the actual positioning process, the lifting device 19 drives the roller frame 17 and the roller shaft 18 to move while the guide rod 12 moves and positions, so as to provide a lifting force for the cuboid blank 20, so that the vertical positioning does not consume too large load, and when the guide rod 12 pushes the cuboid blank 20 to move laterally, only the friction between the cuboid blank 20 and the roller shaft 18 needs to be overcome, so that positioning is realized.

[0045] When the weight of the cuboid blank 20 is relatively light, the lifting device 19 can be a cylinder. The structure of the cylinder is relatively simple, and the cost is lower.
