Technical Field

The invention relates to an iron sheet shearing machine, in particular to a variable-speed iron sheet shearing machine.

Technical Field

Plate shears are commonly used to shear plate blanks at straight edges. The shearing can ensure the linearity and parallelism requirements of the sheared surface of the sheared plate, and reduce the plate distortion, so as to obtain a high-quality workpiece. The blanking shearing tool in the metal plate industry is widely applied to various mechanical industries such as mechanical industry, metallurgical industry and the like, and mainly has the main function that the blanking shearing tool is used for cutting and processing metal plates in industrial departments with more metal plates according to size requirements, so that a plate shearing machine becomes the most widely used plate shearing equipment in each industrial department.

The working principle of the plate shearing machine is that after shearing, the requirements of straightness and parallelism of a shearing surface of a sheared plate can be guaranteed, and plate distortion is reduced as much as possible, so that a high-quality workpiece is obtained. The upper blade of the plate shearing machine is fixed on the tool rest, and the lower blade is fixed on the workbench. The workbench is provided with the material supporting ball so that the plate materials can not be scratched when sliding on the workbench. The rear baffle is used for positioning the plate, and the position of the rear baffle is adjusted by a motor. The pressing cylinder is used for pressing the plate materials to prevent the plate materials from moving during shearing. The guardrail is a safety device to prevent industrial accidents. The return stroke is generally dependent on nitrogen, the speed is high, and the impact is small.

The plate shearing machine is a shearing device widely applied in machining, and can shear steel plate materials with various thicknesses. Commonly used plate shears are classified into 3 types, namely, flat shears, rolling shears and vibrating shears. The flat shears are used in large quantities. Most of the plate shearing machines with the shearing thickness smaller than 10mm are in mechanical transmission, and the plate shearing machines with the shearing thickness larger than 10mm are in hydraulic transmission. Single or continuous shearing of metal is typically performed with a foot or button operated.

The plate shearing machines which are widely applied comprise the following parts:

1. plate shearing machine for cold bending forming line: for example, special plate shears and the like are arranged on production lines such as automobile longitudinal beam cold bending lines, carriage side baffle production lines, color steel plate forming lines and the like;

2. steel structure production line plate shearing machine: the shearing machine is mainly used for an automatic production line of angle steel and H-shaped steel to complete a shearing process;

3. plate shearing machine for plate opening and leveling: the high-speed plate shearing machine is used on a plate uncoiling and leveling line and designed to meet the requirement of fast shearing of the production line speed, most of the thick plate line is a hydraulic high-speed plate shearing machine, and most of the thin plate line is provided with a pneumatic plate shearing machine; the flying shear is arranged on the high-speed line, continuous production is realized, and the efficiency is high.

4. A combined punching and shearing machine: the plate can be sheared, and the profile can be sheared, so that the blanking device is mainly used for blanking;

5. plate bending and shearing machine: namely, two processes of shearing and bending can be completed on the same machine.
