Description

TECHNICAL FIELD

[0001] The utility model relates to the field of oblique multi-section shears, especially relates to an oblique multi-section shear with adjustable inclination angle. BACKGROUND

[0002] In many industrial fields such as metal processing and building material manufacturing, oblique multi-section shears play a crucial role. Oblique multi-section shears are a kind of professional equipment used for segmenting and shearing long strip materials. They are different from traditional straight shearing equipment and adopt an inclined shearing structure. This unique design makes the shearing force distribution on the material more uniform during shearing, effectively reducing the deformation of the material during shearing and improving the shearing quality.

[0003] However, the existing oblique multi-section shears have some problems that need to be solved in practical application. On the one hand, their inclination angles are mostly fixed, making it difficult to meet the diversified needs of different materials and processing techniques for shearing angles. Different materials have differences in material properties, hardness, toughness, etc., and require different inclination angles for optimal shearing effect. For example, high-hardness alloy steel may require a larger inclination angle to reduce shearing force and prevent tool wear, while soft non-ferrous metals can achieve ideal shearing quality with a smaller inclination angle. On the other hand, when facing some special-shaped or sized materials, the fixed-angle oblique multi-section shears cannot be adjusted flexibly, resulting in greater processing limitations and reducing the versatility and production efficiency of the equipment. For example, when processing long strip materials with special curvature, the shearing angle cannot be adjusted to adapt to the shape of the material, making it difficult to ensure shearing accuracy and even causing material waste. These problems seriously restrict the further application and development of oblique multi-section shears in industrial production, and an oblique multi-section shear with adjustable inclination angle is needed to solve the above problems.
