Description

Technical Field

[0001] The utility model relates to the field of metal plate processing and production, in particular to a seamless special-shaped material for a cab of a skid loader. Background Art

[0002] In the prior art, the frame of the cab is welded from conventional round pipes or square pipes of various specifications.

[0003] The above-mentioned prior art has the following defects: the material utilization coefficient of existing conventional pipes is low, and the mechanical properties such as bending resistance and torsion resistance can only be increased by increasing the cross-sectional size. The increase in cross-sectional size will also increase the size of the cab frame and occupy more space. Utility Model Content

[0004] In view of the above-mentioned defects, the utility model provides a seamless special-shaped material for a skid loader cab, thereby solving the problem in the prior art that mechanical properties such as bending resistance and torsion resistance can only be increased by increasing the cross-sectional size, and the frame is large and occupies a lot of space.

[0005] The utility model is implemented using the following technical scheme: a seamless special-shaped material for a skid loader cab, comprising a main body, the main body comprising a first connecting portion, the first connecting portion is bent 90° clockwise and extended to form a second connecting portion, the second connecting portion is bent 90° counterclockwise and extended to form a third connecting portion, the third connecting portion is bent twice clockwise and extended to form a fourth connecting portion, the fourth connecting portion is bent 90° clockwise and extended to form a fifth connecting portion, the fifth connecting portion is bent 90° counterclockwise and extended to form a sixth connecting portion, the sixth connecting portion is bent twice clockwise and extended to connect to the first connecting portion; the first connecting portion is parallel to the fourth connecting portion.

[0006] Furthermore, the thickness of the body is 4.5 mm.

[0007] Furthermore, a third arc and a fourth arc are sequentially connected between the third connecting portion and the fourth connecting portion, the central angle of the third arc is 94° and the radius is 9 mm, and the central angle of the fourth arc is 86° and the radius is 25 mm.

[0008] Furthermore, a seventh arc and an eighth arc are sequentially connected between the sixth connecting portion and the first connecting portion, the central angle of the seventh arc is 105°, and the radius is 9 mm; the central angle of the eighth arc is 75°, and the radius is 25 mm.

[0009] Furthermore, the first connection part and the second connection part are connected by a first arc with a radius of 9 mm, the second connection part and the third connection part are connected by a second arc with a radius of 4.5 mm, the fourth connection part and the fifth connection part are connected by a fifth arc with a radius of 9 mm, and the fifth connection part and the sixth connection part are connected by a sixth arc with a radius of 4.5 mm.

[0010] Furthermore, the straight-line distance from the first connecting portion to the fourth connecting portion is 41 mm.

[0011] Furthermore, the straight-line distance from the second connecting portion to the fifth connecting portion is 24 mm.

[0012] The utility model provides a seamless special-shaped material for a skid loader cab that is different from the prior art in that the utility model changes conventional steel pipes with square or circular cross-sections into steel pipes with special-shaped cross-sections, so that the steel pipes can better fit the cab, thereby increasing the utilization rate of the cab space. Compared with conventional steel pipes, special-shaped pipes generally have larger moment of inertia and section modulus, greater bending and torsion resistance, which can greatly reduce the weight of the structure and save steel. In addition, the special-shaped steel pipe of the utility model is formed in one step by a cold-bending forming machine, thereby increasing its production efficiency.

[0020] like Figure 1 As shown, the utility model provides a seamless profile for a skid loader cab, including a body, the thickness of which is 4.5 mm; the body is composed of a first connecting portion 1, a second connecting portion 2, a third connecting portion 3, a fourth arc 10, a fourth connecting portion 4, a fifth connecting portion 5, a sixth connecting portion 6, and an eighth arc 14 connected end to end. Specifically, the first connecting portion 1 is bent 90° clockwise and extended to form the second connecting portion 2, the second connecting portion 2 is bent 90° counterclockwise and extended to form the third connecting portion 3, the third connecting portion 3 is bent twice clockwise and extended to form the fourth connecting portion 4, the fourth connecting portion 4 is bent 90° clockwise and extended to form the fifth connecting portion 5, the fifth connecting portion 5 is bent 90° counterclockwise and extended to form the sixth connecting portion 6, the sixth connecting portion 6 is bent twice clockwise and extended to connect to the first connecting portion 1; the first connecting portion 1 is parallel to the fourth connecting portion 4.

[0021] As a further illustration of this example, the special-shaped tube of the utility model is formed by cold bending in one step by a cold bending forming machine, thereby increasing the compressive strength of the special-shaped tube.

[0022] As a further illustration of this example, the third arc 9 and the fourth arc 10 are sequentially connected between the third connection portion 3 and the fourth connection portion 4, the central angle of the third arc 9 is 94° and the radius is 9mm, and the central angle of the fourth arc 10 is 86° and the radius is 25mm. The seventh arc 13 and the eighth arc 14 are sequentially connected between the sixth connection portion 6 and the first connection portion 1, the central angle of the seventh arc 13 is 105° and the radius is 9mm; the central angle of the eighth arc 14 is 75° and the radius is 25mm.

[0025] To sum up, the difference between the seamless special-shaped material for the cab of a skid loader provided by the utility model and the prior art is that the utility model changes the conventional steel pipe with a square cross-section or a circular cross-section into a steel pipe with a special-shaped cross-section, so that the steel pipe can better fit the cab, thereby increasing the utilization rate of the cab space. Compared with conventional steel pipes, the special-shaped steel pipes of the utility model generally have a larger moment of inertia and section modulus, and have greater bending and torsion resistance, which can greatly reduce the weight of the structure and save steel. It uses a cold bending forming machine for one-time forming, which increases its production efficiency.
