Automatic cutting machine cutting material has a trimming reason
1, the pad hardness is not enough
With the improvement of work efficiency, the cutting times of the pad becomes more, and the replacement speed of the pad becomes faster. Some customers use low-hardness pads to save costs. The pad does not have enough strength to offset the large cutting force, so that the material can not be simply cut, and then produce rough edges. It is recommended to use higher hardness pads such as nylon, electric wood.

2. Too many cuts at the same position
Due to the high feeding accuracy of the automatic cutting machine, the knife mold is often cut in the same position, so that the cutting amount of the pad in the same position is too large. If the cut material is soft, the material will be squeezed into the cut seam along with the knife mold, resulting in trimming or cutting. It is recommended to replace the pad plate or add the pad micro-moving device in time.
3. The machine pressure is unstable
The frequency of the automatic cutting machine is very high, which is easy to cause the oil temperature to rise. The viscosity of the hydraulic oil will become lower as the temperature rises, and the hydraulic oil becomes thin. Thin hydraulic oil can cause insufficient pressure, resulting in sometimes smooth material cutting edges and sometimes material cutting edges. It is recommended to add more hydraulic oil or increase oil temperature reduction devices such as air cooler or water cooler.
4, the knife mold is blunt or the selection error
The frequency of automatic cutting machine is very high, and the use frequency of knife mold is more than that of ordinary four-column cutting machine, which accelerates the aging of knife die. After the knife mold becomes blunt, the cutting material is forcibly broken rather than cut off, resulting in hairy margins. If there are rough edges at the beginning, we need to consider the selection of the knife mold. Simply speaking, the sharper the knife mold, the better the cutting effect, and the less the chance of edge generation. A laser knife mode is recommended.
Several key points of replacing hydraulic oil by fully automatic cutting machine
As a commonly used industrial cutting equipment, the operator should understand the equipment before taking up the post, master its operation methods, understand its internal structure and the working principle of the equipment, as well as some more common problems in the process of operation, as well as the processing methods. Before using the equipment, we should also carry out a full inspection of the equipment, especially its main components, if there is any problem, we should take measures to solve it, not to let the cutting machine work with disease. The staff must pay attention to this inspection work, to avoid the relatively large mistakes in the process of work, which will seriously affect the whole work.
Automatic cutting machine
The hydraulic oil used in the system for a long time will affect the performance and use efficiency of the oil pressure cutting machine, so we should know exactly when the hydraulic oil needs to be replaced? This mainly depends on the extent that the oil is contaminated. The following are the three methods to determine the oil changing period provided by the fully automatic cutting machine manufacturer:
(1) Visual oil change method.
It is based on the experience of maintenance personnel, according to the visual inspection of some oil routine state changes- -such as oil black, smelly, become milky white, etc., to decide whether to change the oil.
(2) Regular oil change method.
Replace according to the environmental conditions and working conditions of the site and the oil changing cycle of the oil product used. This method is very suitable for the enterprises with more hydraulic equipment.
(3) Sampling and laboratory testing method.
Sample and test the oil in the oil pressure cutting machine regularly, determine the necessary items (such as viscosity, acid value, moisture, particle size and content, and corrosion, etc.) and indicators, and compare the actual measured value of the oil quality with the prescribed oil deterioration standard, to determine whether the oil should be changed. Sampling time: the hydraulic system of general construction machinery shall be conducted one week before the oil change cycle. The key equipment and test results shall be filled in the equipment technical files.
What is the reason for the high oil temperature of the four-column cutting machine
The high oil temperature of the four-column cutting machine does not affect the use of the machine. The oil temperature is related to the displacement. The large displacement machine speed is fast, and the oil temperature heating up is also fast.
There are two main aspects to solve the problem of high oil temperature of the four-column cutting machine:
First, the machine is installed with cooling system, cooling system can be divided into air cooling and water cooling, generally Southeast Asian countries, such as India, Vietnam, Thailand and other countries perennial high weather temperature, in order to extend the service life of the machine, the machine will be required to install cooling system.
Second, the production of four-column cutting machine when the internal structure of the machine adjustment to buffer the displacement of hydraulic oil, this structural adjustment has two benefits, 1, the oil temperature will be lower than the ordinary machine, 2, the accuracy of the machine will be higher than the ordinary machine.
Machine the cooling system and the internal structure of the machine, the cost of the machine will increase.
The above suggestions are for reference, the machine encountered problems, the first time to find the manufacturer, the general machine sign will have the manufacturer’s contact information, the manufacturer will give you reasonable advice.
