How to set automatic die\u00a0cutting machine pressure, here are three suggestions from Shandong Lukes Machinery combined with experience.<\/strong><\/h4>\n

 <\/p>\n

1. Theoretical checking method<\/h4>\n

After the die\u00a0cutting pressure of the automatic die\u00a0cutting machine is converted into line pressure, the pressure value is related to the total length of the steel knife and the steel wire, the effective line pressure and the characteristics of the pressure\u00a0bearing material.<\/p>\n

The current general accounting formula is: P=K\u00d7L\u00d7F<\/p>\n

P\u00a0die cutting pressure (N)<\/p>\n

K\u00a0correction coefficient (generally 1.3)<\/p>\n

The total length of the steel knife or steel wire on the L\u00a0die cutting version (mm)<\/p>\n

F\u00a0Useful line pressure of steel knife or steel wire (N\/mm)<\/p>\n

However, in actual production, due to different materials and environments, the physical parameters such as the tightness, thickness, and fiber direction of the materials are different, and the die\u00a0cutting pressure will change. Wear, the effective line pressure of the steel knife and the steel wire changes, and in the calculation, the steel knife and the steel wire are always allowed to operate at the best effective line pressure value, which results in an error in the theoretical calculation value.<\/p>\n

In addition, because the die\u00a0cutting plate is not completely level during the production process of the die\u00a0cutting plate, the difference in the installation height of the steel knife and the steel wire caused by the error in the machining accuracy of the bridge height reduces the practical performance of the formula. Therefore, this formula cannot be used to determine the pressure of all die\u00a0cutting plates.<\/p>\n

However, the formula still has important guiding significance for the processing process of new production tasks, which has the effect of saving printed sheets and maintaining die\u00a0cutting plates. The biggest practical value of this formula lies in the determination of the reasonable scale of initial pressure. Before the new die\u00a0cutting plate is used, the reasonable theoretical pressure value that can be accepted by the initial use of the die\u00a0cutting plate can be calculated according to the parameter values \u200b\u200brequired by the formula, instead of Reasonable practical pressure values \u200b\u200bfor die\u00a0cut plates. From this formula, it can be seen that the measurement of the die\u00a0cutting pressure and the pressure\u00a0bearing material are mainly balanced by the correction coefficient, but using the same correction coefficient every time will cause the difference caused by the change of the pressure\u00a0bearing material.<\/p>\n

2. Trial cutting method<\/h4>\n

In addition to the checking method, the trial cutting method is also a simple way to determine the die cutting pressure, which is actually an experimental process to determine the die cutting pressure of a certain box shape. This approach is of great help in determining the stress of primary processed commodities. The trial cutting method relies on the operator’s experience to estimate the die\u00a0cutting pressure of new processed products. After finding a reference, gradually increase the die\u00a0cutting pressure until 2\/3 of the die\u00a0cutting line of the die\u00a0cutting proof is blocked. This process called initial pressure. After the initial pressure value is determined, the pressure can be increased by 3\u00a05t according to the characteristics of the pressure\u00a0bearing material. After more than 90% of the steel knives and steel wires have completed normal die\u00a0cutting, the pressure can be increased by 0.1\u00a00.3t until the The die\u00a0cut box type can be separated normally, and this process is called precision pressing.<\/p>\n

This method is time\u00a0consuming and labor\u00a0intensive, and has a high demand for the operator. If the initial pressure is too large, it is easy to cause damage to the die\u00a0cutting plate. If the pressure is too small, repeated experiments are required to reach the rated value, and then the production efficiency is reduced. . However, once a reasonable pressure value is obtained, this value has a very important reference value for future reprocessing, and it is probably recorded one by one for the next use. However, as the wear level of the die\u00a0cutting plate is different, the effective line pressure has changed, resulting in the change of the actual die\u00a0cutting pressure value. Generally, the actual die\u00a0cutting pressure marked must be constantly revised to satisfy the future use.<\/p>\n

Nowadays, factories also generally use the trial cutting method to obtain a reasonable pressure value of new products. If the two are used in combination, it will bring certain economic benefits to actual production.<\/p>\n

3. Comprehensive method<\/h4>\n

The verification method can obtain the theoretical pressure value of the initial pressure, and the trial cutting method can obtain the actual pressure value. If the reasonable practical value obtained by the trial cutting method can be used to reverse the correction coefficient in the verification algorithm, then this type of die\u00a0cutting version can be obtained. Correction factor for this type of data. The correction coefficient is a variable value, which is mainly used to compensate for the difference between different materials and the error between the machining accuracy of the die\u00a0cutting plate of the flat die\u00a0cutting machine. Making more precise determinations so that you can know how much pressure to apply initially when new products are die\u00a0cut can be closer to a reasonable practical pressure value.<\/p>\n

The test method is as follows: Assuming that the initial die\u00a0cutting weight is 300g\/m2 of white cardboard, it is known that the total length of the steel knife on the die\u00a0cutting plate is 1600cm, the total length of the steel wire is 1810cm, and the effective wire pressure of the steel knife used is 45N\/ mm, the useful line pressure of the steel wire is 40N\/mm.<\/p>\n
