Flat Die Cutting Machine Working Tips and Methods

Before the die-cutting operation, how to quickly and accurately setting the equipment is very important. The operator has played a key role. Only by mastering the key points and solutions, the work is more organized and more efficient.

Debugging die-cutting machines generally have the following major points:

1. According to your mold, choose the appropriate template (for the flat die-cutting machine, mainly the upper template, there are three thick, medium and thin: the thick plate is mainly the rubber plate mold, the middle plate is the AB mold, The sheet is a wooden board and an engraving board).

2. Raise the die-cutting machine mold base to the height of the used space of the mold (the so-called die-cutting decompression to the highest, pressurization to the lowest point).

3. Clean the upper and lower mold bases of the die-cutting machine to ensure that the work surface is clean to achieve the flatness of the mold.

4. Use a square ruler to stick the mold vertically to the appropriate position on the upper plate of the die-cutting machine (depending on the size of the die and the material to be materialized, generally centered as well), pay attention to the verticality of the die and the upper plate of the die-cutting machine. There are many kinds of adhesive tapes, such as professional adhesive mold tape (transferable glue), and many other double-sided adhesive edge materials.

5. Place one or two layers of die-cutting plate according to the position of the mold. You can choose hard board such as bakelite or PET to make the bottom plate.

6. Place a mold-adjusting material on the bottom plate, and gradually pressurize the die-cutting machine mold base until it is just pressed to the mold-adjusting material (the knife mark is good for visual inspection).

7. Look at the suppression of the mold-adjusting material, and then use a carbon paper pad to perform a single test under the mold-adjusting material, and print the stamping on the bottom plate clearly.

8. If the embossing is too deep, use a blade to scrape the bottom plate until it is parallel to the bottom surface. (Repeat the process of dressing, pressurizing, pressure test, etc., pay attention to the wide flat adjustment when scraping the line, avoid scraping the template in the form of small groove and uneven way) Adjust the mold to scrape the pad more, if To a little small position, according to the actual situation, the single-sided tape is raised, and a position is at most 1-2 layers of tape.

9. After the mold is adjusted, according to the broadband of the material, a positioning card is attached at a certain position outside the indentation of the bottom plate mold to facilitate material feeding.

10. Everything is ready for the material, and the material is loaded into the discharge rack, and the material is pulled according to the positioning of the card material.

11. Fix the approximate position first, pull in the pulling roller, and jog the pull switch to place the material parallel to the upper die.

12. Connect a piece of release paper or other waste material before production to reduce the loss of the main material and enter the normal production process.

Second, different types of molds (or different process requirements) also have different requirements for the machine

Horizontal and vertical knife molds: the molds are required to be completely parallel to the equipment and materials. In particular, the transverse knives need to be connected in a straight line and must be straight. After such a mold is installed, the material is pressed and tested. If the material is not straight, the locking screw on the mold base is loosened, and the upper mold base is adjusted according to the deviation direction of the mold until it is completely parallel.

Inner jacket mold: This type of mold not only has requirements for parallelism, but also has high requirements for equipment travel. Insufficient parallelism can lead to partial deviations in the products produced, and sometimes the technicians who do not understand the reason think that it is a mold problem. The hop distance is not allowed to lead to an accurate segment of the product. Some think that the device is not allowed to travel, but it is not. You have an error of 0.01mm at a time, and the more you go during the production process, the more you go.

The problem of parallelism is debugged according to the method of horizontal and vertical knives. The hopping problem needs to increase or decrease your hopping according to the actual situation. Many people say: "There is nothing wrong with the design of the hop distance input, then you are wrong. There are errors in the mold making, and the equipment is also in error, so it must be adjusted according to the actual situation.

AB plate mold: The mold adjustment method is the same, just pay attention to the position of the bottom plate paste not to be too close to the blade, it is easy to appear in the product to have the impression. The sleeve deviation can adjust the mold base and the hop distance and adjust according to the actual situation.

High and low knife molds: Some products have full and half breaks. When designing, the mold inserts are set to be high and low. Sometimes there is no high or low blade or not enough, you need to adjust the mold to find their own way. Directly scraping the bottom plate or raising it on the bottom plate is not a long-term solution, and it is difficult to control the production quality, and the mold adjustment operation is difficult. The easiest way is to stick the high-knife position on the back of the mold with tape to the back of the knife (only for inserts such as laser cutters). The machine will automatically come out when the machine is punching.

Engraving and scrapping molds: Many people have also said that the suction and waste can not be completely absorbed, and the suction hole can be adjusted to half-break or full-break debugging according to the material and the mold.
