Technical point of Hydraulic Die Cutting Machine
Hydraulic Die Cutting Machine technology and application of Pang Chunhua With the development of society and people's living standards, consumers in the purchase of goods, in addition to the inherent quality of goods, the packaging of goods also put forward higher requirements, which Which includes the design of the packaging of goods, but also the quality of packaging and postpress processing requirements. Die-cutting indentation is an important production process after finishing, suitable for all kinds of printed surface finishing processing, die-cutting quality directly affects the image of the entire product market, so only to master the traditional die-cutting indentation technology and The new die-cutting technology research and development, in order to effectively enhance the competitiveness of printing enterprises. Die-cutting indentation technology is based on the model indentation and die-pressing two kinds of processing technology, collectively, the principle is in the mold within the mold, by applying the pressure of the size of the printing carrier paper force parts of the compression deformation or Is broken apart.
Die cutting indentation equipment (referred to as Hydraulic Die Cutting Machine) is the main machine die-cutting platform and die-cutting institutions. The sheet is processed between the two is in the pressure under the effect of finishing the finishing of finishing technology. Die-cutting indentation plate has different types and corresponding cutting mechanism, so that Hydraulic Die Cutting Machine is divided into flat pressure flat, round pressure flat and round pressure round three basic types. And flat pressure flat die-cutting machine and because of the version of the plate and the direction of the different positions of different, can be divided into vertical and horizontal two. Flattened Hydraulic Die Cutting Machine This type of Hydraulic Die Cutting Machine plate and die-cutting mechanism are flat shape, when the platform and the platen of the plane in the vertical position for the vertical flat level Hydraulic Die Cutting Machine. Hydraulic Die Cutting Machine at work, the pressure plate by the pressure to the plate and the plate pressure. Press the plate movement trajectory can be divided into two categories: one is the pressure plate around the fixed hinge swing, so at the beginning of the moment of molding, platen surface and the template between a certain tilt angle, so that the cutting cut earlier cut into the lower part of the cardboard , Which is likely to cause the lower part of the die-cutting plate pressure and the upper part of the phenomenon is not completely cut through. In addition, the force of the die-cutting pressure also causes the lateral displacement of the cardboard.
Another pressure plate movement mechanism Hydraulic Die Cutting Machine in the work, the pressure plate in the connecting rod, driven by the cylindrical roller as the fulcrum, in the base of the flat rail swing, until the work surface of the pressure plate from the tilt to the mold Version of the parallel position, and then to the parallel way to the die-cutting die. Vertical flat pressure flat press has the advantages of simple structure, easy maintenance, easy to master its operation and replacement of die-cutting indentation plate, etc., but the labor intensity is bigger, the production efficiency is low, the number of times per minute is 20 times to 30 times, Commonly used in small batch production.
Horizontal flattened flattened Hydraulic Die Cutting Machine version of the platform and platen surface were horizontal position, the following pressure plate by the mechanism to press up to the plate and die-cutting indentation. As the horizontal Hydraulic Die Cutting Machine press the smaller stroke, with manual into or out of the cardboard is more difficult, it is usually with automatic paper feeding system, the overall structure and sheet-fed offset press is similar to the machine from the cardboard Automatic input system, die-cutting part, cardboard output part and electrical control, mechanical transmission and other components, and some also with automatic cleaning device. Horizontal flattening Hydraulic Die Cutting Machine work safe and reliable, its automation and production efficiency are relatively high, is flat pressure Hydraulic Die Cutting Machine in the advanced models.
