[0037] In order to make the technical means, creative features, achieved purposes, and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0038] To improve the convenience of processing and transferring metal workpieces, as Figures 1-3 shown, a lifting device for metal processing according to the present utility model includes:

[0039] A lifting part for lifting the workpiece;

[0040] The hook 5 is arranged on the lifting part;

[0041] The clamping part 8 is arranged on the hook 5.

[0042] During use, a component composed of the lifting part, the hook 5, and the clamping part 8 is used to provide a short-range lifting device for the transfer in metal processing, enabling the flexible transfer of metal workpieces in a processing workshop or site, and effectively reducing the physical exertion of workers during handling, thus improving the convenience of metal processing.

[0043] To improve the flexibility of lifting metal workpieces, for example, as Figure 1 shown, the present utility model further includes that the lifting part includes:

[0047] Hydraulic cylinder 4, connected to the support column 2 and the support arm 3.

[0048] The hook 5 is connected to the bottom of the support arm 3.

[0049] During use, the worker extends and retracts the support arm 3 through the output end of the hydraulic cylinder 4, so that the end of the support arm 3 can reach the required height for use.

[0050] To clamp the metal workpiece, for example, as Figure 2 , 3 shown, the present utility model further includes that the clamping part 8 includes:

[0051] Connecting arm 801;

[0054] Support block 804, connected to the L-shaped support arm 803;

[0055] Pressing wheel 805, arranged on the connecting arm 801.

[0056] During use, place the L-shaped support arm 803 at the bottom of the metal workpiece, and place the pressing wheel 805 at the top of the metal workpiece. As the support arm 3 is lifted, the hook 5 on the support arm 3 drives the clamping part 8 to rise. At this time, the L-shaped support arm 803, the connecting arm 801 and the lifting ring 802 of the clamping part 8 are all subjected to downward pressure, so that the support block 804 on the L-shaped support arm 803 approaches the pressing wheel 805 to realize clamping of the workpiece.

[0057] For example, as Figure 1 shown, the present utility model further includes that the tail end of the support arm 3 is rotatably connected to the support column 2 through a rotating shaft, the sleeve of the hydraulic cylinder 4 is connected to the support column 2 through a rotating shaft, and the output end of the hydraulic cylinder 4 is rotatably connected to the support arm 3 through a rotating shaft.

The pressure wheel 805 and the support block 804 are both made of metal titanium material.

[0061] When the present invention is in use, the worker extends and retracts the support arm 3 through the output end of the oil cylinder 4, so that the end of the support arm 3 can reach the required height for use. The L-shaped support arm 803 is placed at the bottom of the metal workpiece, and the pressure wheel 805 is placed on the top of the metal workpiece. As the support arm 3 is lifted, the hook 5 on the support arm 3 drives the clamping part 8 to rise. At this time, the L-shaped support arm 803, the connecting arm 801 and the lifting ring 802 of the clamping part 8 all receive downward pressure, so that the support block 804 on the L-shaped support arm 803 approaches the pressure wheel 805 to realize clamping of the workpiece. After the workpiece is clamped, the support arm 3 is pushed upward by the oil cylinder 4 to lift the workpiece, and the overall device is pushed through the grip 6, and it moves to the metal processing area based on the casters 7. Subsequently, the workpiece is placed on the processing table or the bracket, and the lifting and transfer of the metal workpiece can be completed.
