Description

Technical Field

[0001] The utility model relates to the field of metal plate processing and production, in particular to a special-shaped pipe 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 special-shaped pipe 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 special-shaped pipe for a skid loader cab, comprising a main body, the main body comprising a first connecting portion, the first connecting portion is bent three times clockwise and extended to form a second connecting portion, the second connecting portion is bent 86° counterclockwise and extended to form a third connecting portion, the third connecting portion is bent three times clockwise and extended to form a fourth connecting portion, and the fourth connecting portion is connected to the first connecting portion.

[0006] Furthermore, a weld is provided at the connection between the fourth connection portion and the first connection portion.

[0007] Furthermore, a third arc, a first arc, and a fourth arc are sequentially provided between the first connecting portion and the second connecting portion, the central angle of the third arc is 35°, and the radius is 8 mm; the central angle of the first arc is 46°, and the radius is 52 mm; the central angle of the fourth arc is 96°, and the radius is 8 mm.

[0008] Furthermore, a sixth arc, a second arc, and a seventh arc are provided in sequence between the third connecting portion and the fourth connecting portion; the central angle of the sixth arc is 115°, and the radius is 8 mm; the central angle of the second arc is 64°, and the radius is 65 mm; the central angle of the seventh arc is 90°, and the radius is 8 mm.

[0009] Furthermore, the second connecting portion and the third connecting portion are connected via a fifth arc with a radius of 8 mm.

[0010] Furthermore, the length of the first connecting portion is 33 mm, the length of the second connecting portion is 3 mm, and the length of the third connecting portion is 6 mm.

[0011] The utility model provides a special-shaped pipe for a skid loader cab that is different from the prior art in that the utility model changes a 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, special-shaped pipes 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. 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.

[0018] At the same time, in the description of the present invention, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] like Figure 1 As shown, the utility model provides a special-shaped pipe for a skid loader cab, including a body, the thickness of which is 4 mm. The body includes a first connecting portion 1, the first connecting portion 1 is bent three times clockwise and extended to form a second connecting portion 3, the second connecting portion 3 is bent 86° counterclockwise and extended to form a third connecting portion 4, the third connecting portion 4 is bent three times clockwise and extended to form a fourth connecting portion 11, and the first connecting portion 11 is connected to the first connecting portion 1.

[0020] As a further illustration of this example, the special-shaped tube of the utility model is cold-formed by a cold-former, and a weld 12 is provided at the connection between the fourth connecting portion 11 and the first connecting portion, thereby increasing the compressive strength of the special-shaped tube.

[0021] As a further illustration of this example, a third arc 6, a first arc 2, and a fourth arc 7 are sequentially arranged between the first connection portion 1 and the second connection portion 3. The central angle of the third arc 6 is 35° and the radius is 8mm; the central angle of the first arc 2 is 46° and the radius is 52mm; the central angle of the fourth arc 7 is 96° and the radius is 8mm. A sixth arc 9, a second arc 5, and a seventh arc 10 are sequentially arranged between the third connection portion 4 and the fourth connection portion 11; the central angle of the sixth arc 9 is 115° and the radius is 8mm; the central angle of the second arc 5 is 64° and the radius is 65mm; the central angle of the seventh arc 10 is 90° and the radius is 8mm.

[0022] The second connection part 3 and the third connection part 4 are connected by a fifth arc 8 with a radius of 8 mm. By using an arc instead of an angle connection, the mechanical strength of the special-shaped tube of the utility model is further increased.

[0023] As a further illustration of this example, the length of the first connection portion 1 is 33 mm, the length of the second connection portion 3 is 3 mm, and the length of the third connection portion 4 is 6 mm.
