The invention provides a novel multifunctional punching and shearing machine material pressing device. The novel multifunctional punching and shearing machine material pressing device comprises a rack, a fixing bolt, double thread lead screws, box iron, compression sliding blocks, a support, a bolt, angular contact bearings and a bearing block; the support is fixed to the rack through the fixing bolt, a dovetail groove is designed in the support, the compression sliding blocks are designed to be swallow-tail form sliding blocks, thread holes are machined in the two compression sliding blocks, and rotation directions of threads of threaded holes of the two compression sliding blocks are opposite; and the compression sliding blocks are arranged in the dovetail groove of the support, the double thread lead screws are connected with the two compression sliding blocks and are installed on the support through the angular contact bearings, and the box iron is arranged in a punching and shearing machine cutter groove. Rotation directions of threads at the two ends of the double thread lead screws are opposite, when the box iron is machined through the punching and shearing machine in a punching and shearing manner, the double thread lead screws are rotated, the two compression sliding blocks conduct centering clamping on the box iron from the two sides, and therefore the box iron cannot move, the shearing accuracy is high, and operation is convenient and rapid. The novel multifunctional punching and shearing machine material pressing device is simple in structure, easy to popularize and good in economic benefit.
Description
technical field [0001] The invention relates to a pressing device of a punching and shearing machine for punching, punching and shearing a plate, in particular to a novel multifunctional pressing device of a punching and shearing machine, which belongs to the field of mechanical processing equipment. Background technique [0002] The multifunctional punching and shearing machine is a sheet metal and profile processing equipment that integrates multiple functions. It can process plates, square steel, round steel, angle steel, channel steel, and I-beam by cutting, punching, and die cutting. Widely used in modern machinery manufacturing industries such as metallurgy, bridges, communications, and electric power. In order to prevent the workpiece from moving or turning over during the shearing process, it is necessary to design a pressing device at the material inlet of the punching and shearing machine. Compress the workpiece to improve the cutting accuracy, prolong the service ...
