For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0027] like Figure 1-2 As shown, an embodiment of a combined clamp for aluminum alloy raw materials includes a slide rail 1 extending along a first direction, two main clamping arms 2 slidably connected to the slide rail 1, the main clamping arms 2 are fixedly provided with clamping members 3, and the clamping members 3 of the two main clamping arms 2 are arranged opposite to each other along the first direction; the free end 202 of the main clamping arm 2 away from the slide rail 1 is detachably connected to an extension clamping arm 4.

[0028] The first direction is the length extension direction of the slide rail 1 .

[0029] The two main clamping arms 2 can move relative to each other along the first direction, and the distance between the two main clamping arms 2 along the first direction can be adjusted according to the different volumes of the aluminum alloy raw materials to be clamped. Therefore, the coordinated arrangement of the slide rail 1 and the two main clamping arms 2 can adapt to aluminum alloy raw materials of different volumes and expand the clamping range.

[0030] A clamping member 3 is provided. Preferably, the clamping member 3 is provided at one end of the main clamping arm 2 away from the slide rail 1, which is suitable for clamping aluminum alloy raw materials with a smaller volume, so that the clamping member 3 can concentrate the force and achieve stable clamping.

[0031] An extended clamping arm 4 with various structures is provided, which is extended in length and / or width on the basis of the main clamping arm 2, i.e., along the first direction and / or along the length extension direction of the main clamping arm 2, so as to clamp aluminum alloy raw materials with longer length and wider width and expand the clamping range; the extended clamping arm 4 is detachable from the main clamping arm 2 for easy replacement, thereby reducing the loss, maintenance and replacement costs.

[0032] like Figure 1-2 As shown, in another preferred embodiment, the extended clamp arm 4 is sleeved on the main clamp arm 2 , and a limiting structure is provided between the extended clamp arm 4 and the main clamp arm 2 , and the limiting structure is used to fix the extended clamp arm 4 to the main clamp arm 2 .

The obtuse angle design is more suitable for clamping a rolled aluminum alloy raw material.
