Spare part replacement method: When the failure of the hydraulic shears is analyzed and it is found that the circuit board may be faulty, the spare part board can be used for replacement, and the faulty circuit board can be quickly determined.
Secondly, there are many buttons on the shearing machine, which is also an important issue for inspection and maintenance. As the person in charge of the job is using the shearing machine, the buttons inside are often used during the production of finished products. We know that no matter what is used and used for a long time, it will be aging and fragile, so the button is also an object that is often checked. Assuming that the button is exposed and easy to swing, it should be replaced in time. Of course, assuming that the shearing machine is often maintained during the application process, the CNC shearing machine is very difficult to use.
Lubricant method: Lubricant Lubricant amount: Small (16 hours / time) Lubricant type: Calcium-based lubricating grease (butter) The left and right return cylinders are filled with pure nitrogen at a certain pressure, which is cut by a hydraulic shear After the completion of the device, the hydraulic shearing machine will return. Frequent movement back motion requires frequent lubrication.
Lubrication method: Lubricant amount: Medium (8 hours / time) Lubricant type: Calcium-based lubricating grease (butter), which is driven by the back-gauge motor to the screw cap to complete the adjustment of the back-gauge. The back and forth adjustment of the back gauge of the hydraulic shears makes the lubricant very demanding.
Finally, check the pressure of the nitrogen atmosphere of the accumulator of the shearing machine. The pressure of the normal nitrogen atmosphere is 4-5 MPa. Before the machine tool starts work, you should carefully check whether the work station is placed properly, and the area of the workbench or model area. Is there anything abnormal? Only after clearly acknowledging that there are no abnormal materials, can the work machine be started.
Why do nitrogen cylinders in hydraulic shears prevent air leakage? In the view of Wuxi Shenchong, a manufacturer of hydraulic shears, the specific reason for this problem is: assuming that the nitrogen cylinder leaks, then the tightly sealed closure in the nitrogen cylinder is damaged. Suppose that in such a long period of time, the piston rod will be worn, and then the nitrogen cylinder is discarded, which cannot be used normally and affects the normal operation of the shearing machine. It is necessary to prevent air leakage.
In summary, the metal cutting speed has a large impact on the shearing effect, but suppose that you want to increase the speed of the shearing machine, and have high requirements for the shearing machine. Well, otherwise the shearing machine is easy to fall apart. Only a few companies such as Wuxi Shenchong have experience in manufacturing this high-speed shearing machine in China.
There is also a mechanical shearing machine called precision shearing machine, which is more suitable for manufacturers with high cutting accuracy
Always pay attention to abnormalities or malfunctions of the locking mechanism, separator, brake, and pedal switch. When cutting sheep's hair, we should concentrate our energy. Assuming that the equipment shows an abnormal phenomenon, you should immediately stop cutting, cut off the power, and notify the person in charge of maintenance to perform maintenance.
The high-speed cross-cut flying shears are used to quickly cut the rolling parts moving in the transverse direction. It started at the end of the nineteenth century. Through one hundred years of development, the types of flying shears used in the production process have been taught. Until now, the more widely used flying shear shapes are: disc flying shears, roller flying shears, crankshaft curved part connecting rod type flying shears, crankshaft curved parts unfair, formal flying shears, pendulum flying shears, crankshaft curved parts connected It can be seen from the material situation of the flying shears and the development requirements of wire rod production that the flying shears have the following two aspects:
Meet the scope of application: a wide range of uses. It is especially suitable for aviation, ships, vehicles, metal smelting, machinery and electronics, household appliances, ventilation ducts, printed iron products, steel structure construction, engineering decoration industry, and the entire metal and non-metal sheet processing industry.
NC Shearing Machine This kind of shearing machine, if you want to adjust the blade gap, then, from a professional point of view, it should be determined and carried out according to the thickness of the material to be cut. Assume that the thickness of the material is 1-3mm. Then, the cutting edge gap adjustment number is 1-2mm. The thickness of the material is 4-10mm, then the cutting edge gap adjustment number is 3-5mm.
Wuxi Shenchong reminds that there are also several important details that need to be paid attention to in the process of calculating the number of controlled shearing machines. First of all, you should check the power supply lines of the shearing machine and the power supply before each start-up to see if the circuit After using for a long time and aging, check whether the line is cut off by rats and other animals. Once it is not well connected due to wiring problems, etc., it is easy to burn out the shears during use.
