The present invention relates to a high-speed press using a link mechanism. In general, in the case of a double link press, the link mechanism is installed on both sides. When the mechanism is installed, it is possible to make two linkages the same and to reduce the effort for aligning the two positions. The large area of the slides and bolsters can be used effectively for large-sized work. It relates to a high-speed press used.

Currently, the press machine among the machine tools is an important machine as a sheet metal processing machine widely used in all industries. General machine tools such as lathes and milling are becoming precise, advanced and NC, but presses are not. However, unlike other machine tools, presses are punching machines, which generate vibration and processing noise when punched. In addition, as the trend of press processing is changed from single mold processing to progressive processing, which is a sequential processing, the noise during processing increases. Therefore, in the press industry, it is important to find ways to significantly reduce noise and vibration while increasing productivity through progressive processing.

In general, mechanical presses are classified into crank presses, crankless presses, knuckle presses, link presses, cam presses, and so on. This press is used for cold forging. It is suitable for coining and extruding work because of long pressing time at bottom dead center, but it cannot be used for drawing work. Cam press is softly contacted when the upper mold comes into contact with the lower mold during product punching. Therefore, the press amount rises and the cam press displays the product forming area according to the cam diagram. Therefore, the cam has to be redesigned every time the product is changed.

The link press is equipped with a link in the drive unit, so that the slide motion can be lowered rapidly from the top dead center to a certain section and then operated slowly in the product forming section, and the product can be rapidly returned to the top dead center after the product molding. Since the upper mold and lower mold are softly touched when forming the product, there is an advantage of low punching noise and long life of the mold and punch.

 In the conventional technology, the distance of the slide point portion is formed inside the slide area to generate vibrations for eccentric loads, and the link connection part is composed of a plurality of links, which is complicated and the power converter is driven by a screw. Can not be long, and had a problem in terms of vulnerability.

In order to solve the problems described above, in the present invention, the drive shafts installed at both sides are driven simultaneously by the main main gear and the link, and the balance weights are installed at both sides of the frame to suppress the vibration of the press even at a high slide speed and The press itself can be operated stably without torsion or deflection, and the product can be molded smoothly, and a high speed press using a link mechanism that can form shallow drawing or precision parts at high speed by a single link mechanism is provided.
