Shearing involves cutting sheets of metal, bars, or plates using shear force through a die and a tool that’s very similar to the paper punching process. The punch and die could be in various forms, including circular or straight blades that can behave similarly to scissors. Shearing machines comprise blanking machines that are used to make washers, punching equipment used to make small discs, etc. Shearing is typically used to separate metals into sheets or strips. Shearing strips, sheets, or plates is dependent on the type of blade that is used to shear which can be a straight or rotatory. The hydraulic shear is a powerful machine that efficiently cuts through various materials with precision and ease. Rajesh Machines is a reputed provider of shearing machine manufacturers.
To cut and square flat stock to the desired sizes and shapes, straight knife shearing is utilized. Straight shearing of a straight knife is utilized to create square and rectangular shapes. Many straight-sided shapes are also available through straight knives. The shearing machine price depends on various factors such as size, capacity, and advanced features.
The Mechanism Of Shearing Machine
The shear cutting or punching actions result from the close movement between two edges that are close to each other and the material is placed between the edges. Shear stresses are applied near the place of fracture and are divided into three phases:
- Deformation: The deformation occurs on the two sides of the workpiece that is directly adjacent to the cutting edges from the moment the cutting begins close to the material.
- Permeation: Cutting edges penetrate or cut the material resulting in fracture lines.
- Fracture: It can also be described as the point where the lower and upper fracture lines intersect. It is at this point that work is completed, but in the case of punching, the process is carried on until the material is able to move through the slug.
Types of Shearing Machine
There are many types of shearing machines that could be used to satisfy the specific requirements of your job.
