The Cut to Length Line is specially designed to cut metal sheets of different raw materials and thicknesses from coil cross-section to sheet, straighten the sheets and cut them to a certain length. The basic process includes unwinding, straightening, cross-cutting and stacking, etc. It realizes a fully automatic cut-to-length production process and produces sheet products that serve the customer's dimensional requirements and are put into secondary processing for use, which is widely used in the automotive manufacturing, machine building and metal processing industries.
For different thicknesses and different raw materials of the original material, and then cut to length shearing line production process how to ensure that the progress and speed of the shear?
What is the principle of cut to length machine shearing?
First of all, you need to understand the scope of the process of metal coil before entering the shear machine include:
1. Material feeding: The sheet metal is fed into the shear by means of a feeding device (e.g. rollers, conveyor belts, etc.). The feed device ensures that the sheet is fed smoothly and continuously into the shearing area.
2. Positioning and clamping: In order to ensure shear accuracy, the sheet metal needs to be accurately positioned before shearing. Positioning devices (such as positioning pins, photoelectric sensors, etc.) to determine the position of the plate, clamping devices (such as hydraulic fixtures) to fix the plate to prevent it from moving during the shearing process.
1. Precision leveling: a device specialized in straightening metal plates or strips, mainly used to eliminate bending, ripples and other uneven defects produced during the production and processing of materials, thus improving the flatness and quality of materials. A number of sets of leveling rollers arranged up and down are usually set up inside. These rollers are driven mechanically or hydraulically to repeatedly bend the material between the upper and lower rollers.
Principle of shear host equipment:
The core part of the shearing machine is the shearing blade, which usually includes the upper blade and the lower blade. The material of the blades is usually high-strength alloy steel, after a special heat treatment process to ensure its hardness and wear resistance.
Slider movement: shears are usually driven mechanically or hydraulically to move the upper blade along the vertical or diagonal downward movement, and the fixed lower blade to form a shearing force.
Shear force action: When the upper blade is pressed down, the sheet is subjected to shear force action between the upper and lower blades. When the shear force exceeds the shear strength of the material, the plate breaks along the shear line, completing the shear.
Waste material discharge: after the shear is completed, the sheared sheet and waste material are discharged through the conveyor or waste chute.
Meanwhile, modern shears are usually equipped with computer numerical control (CNC) systems. The control system is programmed to set the shearing parameters (e.g., shearing length, quantity, etc.), with a high degree of automation, which can improve productivity and shearing accuracy.
