How to deal with the cutting machine before and after the failure
Simple fault and maintenance of the cutting machine
1) Ask the equipment operator to perform the equipment. These include: whether the hydraulic system works normally; whether the hydraulic pump of the hydraulic cutting machine is abnormal; the time and result of hydraulic oil detection cleanliness; cleaning and replacement of the filter element; whether the hydraulic element has been adjusted before the failure; whether the sealing element has been replaced; what abnormal phenomena have occurred in the hydraulic system before and after the failure; what faults have occurred in the past, and how the troubleshooting should be understood one by one.
2) Look at the actual condition of the hydraulic system, and observe whether there are problems in the system pressure, speed, oil, leakage and vibration.
3) Listen to the sound of the hydraulic system, such as impact sound; noise and abnormal sound of the pump, and judge whether the hydraulic system works properly.
4) Touch the temperature rise, vibration, crawling and the tightness of the joint to determine whether the working state of the moving parts is normal.
No light on after the hydraulic cutting machine:
fault analysis:
1, transformer insurance burned;
2. The brake switch is not turned on.
Maintenance and treatment method of automatic cutting machine:
1. Replace the fuse;
2. Turn on the power supply and the brake switch.
After startup, the cutter indicator is not on but the energy motor can start:
Fault analysis: indicates the bulb to burn out.
Treatment: Replace the indicator bulb.
Then the indicator can start the motor but does not work properly:
fault analysis:
1, the motor protection switch jump speed;
2, the main control contactor is bad or burned;
3. The motor is burned down.
Maintenance and treatment method of cutting machine:
1. Turn on the switch;
2. Replace the contactor;
3. Change the motor.
Transmission mode, structure and use of the cutting machine
1, according to the transmission form points:
A, mechanical transmission cutting machine: it is A relatively old machine.
B, Hydraulic transmission cutting machine: it is a modern common cutting machine, according to the age can be divided into the first generation of plane guide rail hydraulic cutting machine, the second generation of ordinary four-column hydraulic cutting machine, the third generation of precision four-column hydraulic cutting machine and gantry mobile hydraulic cutting machine., Automatic rolling cutting machine: with the method of sandwich processing the whole leather or textiles.
D. Computer controls the water beam
Cutting machine: is a modern more advanced cutting machine, do not need to use the knife mold, according to the input program for cutting. The cutting source is the high pressure beam generator.
E. Computer-controlled ultrasonic cutting machine: the control form is similar to the water beam cutting machine, and the impulse and cutting source is the ultrasonic generator.
2. According to the structure mode:
A, rocker arm cutting machine: cutting parts can be swinging the rocker arm, suitable for leather, natural materials and artificial leather and other non-metal materials.
B. Longmen moving cutting machine: the cutting parts are the cutting head that can be moved along the side of the beam. The knife mold can be fixed on the cutting head or placed on the processed material. The large and computer-controlled gantry cutting machine is equipped with a rotating knife die frame, which can be selected according to the program typesetting; and an automatic feeding mechanism shall be provided accordingly.
C, flat plate type cutting machine: the difference between it and the gantry type cutting machine is that the beam directly cutting, there is no movable cutting head.
Flat plate cutting machine is divided into: beam fixed or beam can be moved back and back and the platform skateboard can be moved front and back two categories.
D, four-column precision
Cupping machine: double cylinder, four-column automatic balance connecting rod structure.
3. According to the purpose of the processed parts:
A, special cutting machine: suitable for the blister processing of the suction plastic cutting machine.
B, horizontal cutting machine: suitable for processing tire materials.
Performance and characteristics of the hydraulic cutting machine
1. Computer control system, touch screen display, simple operation, fast and accurate.
2. Double cylinder, four-column automatic balance connecting rod structure, to ensure that each cutting position cutting depth is exactly the same.
3. The automatic cutting machine can be combined with a single-sided or double-sided automatic feeding device, improving the production efficiency of the whole machine by two to 3 times.
4. The cutting plate is automatically cut slowly when touching the cutting plate, so that there is no dimensional error between the top and bottom layers of the cutting material.
5. Special setting structure, with the cutting knife and cutting height, so that the stroke adjustment is simple and accurate.
6. The central automatic lubrication system ensures machine accuracy and improves machine durability.
