In the program-controlled paper cutting machine, the blade is one of its important components. Its sharpness and service life can determine the production efficiency of the paper-cutting machine to a large extent. Then the use of the program-controlled paper cutting machine is determined. What are the main factors such as service life?
        First of all, as far as the material of the blade is concerned, the blade and the blade body are welded at high temperature. The blade is made of high hardness chromium tungsten manganese steel, and the blade body is made of low carbon steel. In terms of the durability of its cutters, it is directly proportional to the hardness of the steel used in the blade. When its quality is high, its hardness can reach HR55 ~ 60 after quenching treatment.
        Secondly, in terms of the shape and angle of its sharpening blade, in single-sided paper cutters, we generally use a single sharpening blade with an angle between 19 ° and 23 °, but at the same time, the sharpening edge of this shape It will cause the beveled surface of the cutter to withstand the pressure of the part of the paper stack that is cut away during the cutting process. Under the friction of the paper edge, the beveled surface of the blade will wear quickly. Compared with single-sided blades, double-sided blades have more obvious advantages. Their sharpening edges can effectively reduce the load on their machines and improve their accuracy. Therefore, on the premise that the cutting edge material is allowed and the cutting force is not considered, the angle of the sharpening edge should be made as small as possible.
        Of course, in terms of the quality of the sharpening knife, of course, the higher the quality, the longer the service life of the cutter and the better the cutting quality.
        In fact, the life of a computer cutting machine is also related to its cutting material, such as the blunt speed of its blade and its abrasion resistance, when the paper is cut, the texture of the paper is soft and hard, the ash content, etc. All are related. Generally speaking, when the paper is cut, the harder the texture and the larger the ash content, the faster the blade becomes blunt.

         Some users have found that sometimes there is no phenomenon when the secondary pressure of the paper presser appears during the cutting of the hydraulic paper cutter, which is very easy to cause the cutting material to be scrapped due to the size deviation, causing great waste. So what is the reason for this problem? How to solve it?
         There are two main reasons for this problem. The first reason is that the pressure relay of the hydraulic system is improperly adjusted, and it has been activated when the foot is tested; the second reason is that a relay in the electrical box The K5 contact is caused by a bad contact. The K5 relay controls a solenoid valve coil, and this solenoid valve controls the high-pressure hydraulic oil to enter the oil cylinder of the press, thereby causing the press to operate. By replacing K5 and adjusting the pressure relay to the secondary pressure of the paper presser, it will act. That is, when the foot pressure is tested, the pressure relay will not be activated. After the adjustment is completed, the top wire will be locked and then try again You will find that the fault still disappears.

         The paper cutter is a device for processing paper cutting. It has more advantages than other paper cutters. So what advantages does it have? The following will be specifically explained by Xiaobian.
         First, the hydraulic paper cutter cuts text of different materials, and the processing speed is also relatively fast. And it can ensure that the cut object has a certain degree of accuracy after being cut. When cutting larger-density cut objects, the difference between it and ordinary paper cutters is particularly obvious, and customers who require higher cutting accuracy You can choose it. The dual-hydraulic computer paper cutter is a device controlled by a microcomputer program. The pressure of the paper can be set by the computer, and it can automatically complete the actions of pushing, pressing and cutting. The specially designed knife lock can also effectively prevent the phenomenon of sliding knife.
         The above are the advantages of hydraulic paper cutters. I hope Xiaobian's answer can be helpful to Xiaojia.

         Hydraulic paper cutter is a kind of paper cutter. It operates by hydraulic oil to control the operation of the cutter. It is suitable for cutting dense paper with higher cutting accuracy than mechanical type. In the cutting process, the blade is a very important part. The life and sharpness of the blade affect the working efficiency of the paper cutter, so it is necessary to pay attention to the maintenance and maintenance of the blade daily.
        In order to maintain the sharpness of the blade, the thickness of the cut paper should not be too thick, preferably not more than 40mm, and the pressure of the hydraulic paper cutter should be different for different paper materials. In order to have high cutting accuracy, it is necessary to regularly check whether the blade is blunt, and sharpen the sharp blade in time. Operators should always prepare to replace the blade to prevent the blade from being damaged during the cutting process and delaying time. It is necessary to consider the temperature and humidity of the environment. The appropriate temperature and humidity are conducive to the operation and cutting stability of the hydraulic paper cutter.

         As its name implies, it is a paper cutter with a hydraulic device inside, which can cut very thick documents. It is mainly composed of the host, the workbench, the paper pushing mechanism and the cutting. The hydraulic paper cutter can accurately ensure the consistency of the length and width after cutting, and has controllability.
         What is the difference between a hydraulic paper cutter and an electric paper cutter? Hydraulic paper cutting machine has hydraulic oil inside, which is operated by hydraulic device. When cutting soft paper, it sometimes cuts imperfectly and is not suitable for cutting small batches of documents. The hydraulic paper cutting machine can cut leather, rice paper, kraft paper and other Material text, very fast, suitable for use in libraries and publishers.
         The electric paper cutter is purely mechanically controlled, which is convenient for cutting small batches of text.
When using a hydraulic paper cutter, pay attention to the ground wire. Always oil the bottom of the push bar. Periodically check the gap between the screw and nut to prevent it from hitting the paper pusher. Also check the encoder and hydraulic oil regularly. Please follow the instructions. Requirements for hydraulic oil.
