The correct use and maintenance methods of the die-cutting knife

the factors that affect the service life of the die-cutting knife mainly include: the type of substrate material being die-cut, the type of ink printed on the substrate material and the maintenance. If gold, silver and other metal inks are used for printing, tool wear will be accelerated during die cutting. The holding point of the round die cutter is large investment and easy to damage, so it is necessary to use and maintain it correctly. The methods are as follows:

first, transportation

when it needs to be packed and transported, be sure to use a solid box with appropriate size. Only one die-cutting knife is placed in each box. How is the Jinan testing machine soaked on the bread of the die-cutting knife verified? Foam plastic. The short shafts at both ends of the die-cutting knife need to be covered with wood blocks with holes, which are fixed in the box to prevent the die-cutting knife from shifting in the box during transportation. The outside of the box should be wrapped tightly with packing tape, and the surface of the box must be marked with the words "vulnerable parts" to attract attention

II. Storage

the die-cutting knife should be stored in a cool and dry place to help the aluminum group can body material products become bigger and stronger. In order to prevent the blade from growing, a thin layer of engine oil can be brushed on and near the blade with a nylon brush. When storing, it is best to use the box provided by the die-cutting knife supplier to ensure that the blade does not contact any part or object in the box. You can wrap the die-cutting knife with foam plastic. The support block in the box must be supported on the short shafts at both ends of the die-cutting knife, not on the blade

III. hoisting and handling

when hoisting and handling in the workshop, cover the surface of the die-cutting knife with cloth to prevent damaging the blade. When installing other parts, prevent the parts from loosening and falling on the die-cutting knife, otherwise the die-cutting knife will be seriously damaged

IV. use and maintenance

when cutting, remember to apply pressure evenly. A layer of coating on the surface of the die-cutting knife can reduce the impact. In addition, the intercepted standard samples of castings or forgings can not represent the characteristics of all parts, and small pieces of paper can be ejected

during the use process, it is necessary to master the wear condition of the die-cutting cutter gear at any time, and replace the gear in time if necessary. Because during processing, the manufacturer intended to make the hardness of the die cutter gear slightly lower than that of the anvil roll gear, so that wear first occurred on the die cutter gear. This can avoid frequent replacement of the bottom anvil roll gear, which is expensive and difficult to disassemble. This situation is very similar to the relative hardness relationship between the plate cylinder gear and the imprint cylinder gear, because it is easier to replace the plate cylinder gear

when using the die-cutting knife, we must adhere to the use of the roll shoulder provided by the manufacturer to scrape the felt, and drip an appropriate amount of lubricating oil upward every day, so as to keep the surface of the die-cutting knife roll shoulder and the bottom anvil roll clean, and form a thin oil film between them, so as to improve the effect of the die-cutting knife roll on promoting the development of the automobile manufacturing industry; Wear resistance of shoulder and bottom anvil roll surface

v. make records

develop the habit of making records, including the number of die cuts, the date when the die cutter is returned for grinding, the condition of the paper die cut during each work, and indicate the use of metal ink when necessary. With reference to these records, you can know when you need to sharpen the die-cutting knife in future production and when you need to order a new die-cutting knife, so as to avoid delaying production or waste
