Hydraulic guillotine shearing machine suppliers have a strong economic strength foundation, excellent production environment conditions, advanced production process equipment, mature production and manufacturing system, rich production and manufacturing experience, first-class research and development level, and implement strict operating specifications and product inspections. Standard, to ensure the high quality of products and services.
Hydraulic Guillotine Shearing Machine Suppliers Have Strict Requirements
The cutting tools of hydraulic guillotine shearing machine suppliers have changed the transmission mode of traditional shearing machine machines. Each machine absorbs international and foreign traditional skills and adopts the electromagnetic disc shape effect. The trade-off is that the control of the footswitch is instantaneously engaged, the cutting position and the slanted cutting position so that the bending deformation of the additional piece is raised to the minimum limit.
The blade gap adjustment of hydraulic guillotine shearing machine suppliers adopts manual, quick adjustment installation, which can be extremely troublesome to obtain the desired blade gap. A machining and shearing facility that makes non-metallic non-metallic sheets realistic.
Shearing Machine Relief Valve
If the shearing machine of hydraulic guillotine shearing machine suppliers overflows and the machine tool cannot work normally, it is necessary to clean the overflow valve or the valve below. So how to clean the overflow valve? When the machine tool steps on the footswitch, the valve light is already on, but the tool holder does not go down, and the cutting action is not completed, which means that the problem is the oil circuit; then, we need to clean the valve.
Hydraulic Guillotine Shearing Machine Suppliers Tell You The Cleaning Steps
The steps to clean this valve are first to find a 4mm wrench because these are 5mm socket head cap screws. First, remove the upper layer, remove the four screws, and then pay attention to the O-ring. If it sticks to the bottom, it needs to be installed. Make sure that the sealing ring is completely installed on it.
Then remove the second layer or four screws. Remove them in turn. After taking them off, you will see a spring. This O-ring also needs attention. If it sticks to the bottom, it must be installed. Otherwise, install it. There will be oil leaks here.
Put the removed two layers aside first; there is a valve core in the hole produced by hydraulic guillotine shearing machine suppliers. Under what circumstances does the valve core need to be removed? When the machine tool does not work properly and cannot generate pressure. Why is there no pressure? The valve core is stuck by foreign objects or metal scraps inside. At this time, take out the valve core and observe it. First, check whether there is any problem around the valve core, and then check whether there is metal scrap or foreign matter stuck in the hole so that the valve core cannot work back and forth normally.
In general, hydraulic guillotine shearing machine suppliers will reach in with their hands and gently look for foreign objects. If there are foreign objects, the hands will feel obvious. Then find a magnetic screwdriver, put it in, and look for it. It will be adsorbed on the screwdriver and taken out if it is metal scrap. After confirming that there is no problem in this hole, ensure that the valve core is no problem.
Hydraulic guillotine shearing machine suppliers will move the spool back and forth when it is installed to see if the spool can work properly. After the valve core is installed, install the spring. Some springs have a small gland on them. If there is a small gland, it should be installed on the upper end of the spring.
Since the two ends of this spring are the same in shearing machines produced by hydraulic guillotine shearing machine suppliers, no installation is required. When installing the second layer of the valve, pay attention to ensuring that the O-ring is complete and tighten the valve diagonally after the valve body is established. When installing the first layer of the valve, please pay attention to whether there is any problem with the O-ring and tighten it diagonally.
When the machine tools produced by hydraulic guillotine shearing machine suppliers cannot make normal working pressure, it is necessary to clean the overflow valve. When the pressure is abnormal, or there is no pressure, although the valve light is on, no force is generated; the valve needs to be cleaned.
Hydraulic Guillotine Shearing Machine Pressure Adjustment
The side of the shearing machine produced by hydraulic guillotine shearing machine suppliers is a gear-shaped valve used to adjust the pressure. If it is clockwise, it will increase the pressure, and if it is counterclockwise, it will decrease the pressure. The pressure will be displayed on this pressure gauge. However, the total pressure value cannot be seen in the empty test machine under normal circumstances.
You must find a thick plate that exceeds the unit of the machine tool. For example, the Hydraulic guillotine shearing machine is 6*2500. You need a 10mm or 12mm container to put it inside and add pressure, and then the pressure gauge will increase to the maximum pressure when it cannot be cut, and the pressure will generally be adjusted to twenty. Hydraulic guillotine shearing machine suppliers have loosened this valve during maintenance, so an adjustment is needed, clockwise is to increase, and counterclockwise is to decrease, knowing that this is enough.
Hydraulic Guillotine Shearing Machine Sequence Valve
What is the function of the sequence valve? When adjusting the shearing angle of the gate shearing machine, the valve will increase the initial pressure of the machine tool, and this initial pressure is used to adjust the shearing angle. The specific pressure will be displayed on the pressure gauge. Generally, the valve pressure will be adjusted to 8Mpa.
If the angle cannot be adjusted or the angling pressure is small, the valve needs to be changed. If the valve has been twisted clockwise to the end, the initial pressure on the pressure gauge here still does not increase, or the increased pressure is not enough to reach 8Mpa, the valve needs to be cleaned.
How Do Hydraulic Guillotine Shearing Machine Suppliers Clean Valves?
First, the manufacturer of hydraulic guillotine shearing machine suppliers will remove these four screws. After extracting, you will see a spring, pay attention to checking the O-ring, and press it back to its original position.
Take out the small pressure ring together with the spring; there is a valve core, and pull it out by hand. After pulling it out, observe whether there are metal scraps or foreign objects on the surface of the valve core, which must be kept clean and tidy.
If the valve core is normal, put it aside, and then put the hand of the hydraulic guillotine shearing machine suppliers staff into this hole to observe, and look for any foreign matter stuck in the hole. Or find a magnetic screwdriver and put it into the hole to see if it can suck out foreign objects such as metal scraps.
After confirming no problem or foreign matter, reinstall the valve core. When the поставщики гидравлических гильотинных ножниц staff put the valve core back by hand, check whether the valve core can work normally; then put the spring and small pressure ring back, and the small pressure ring is in On; then the O-ring, to ensure that the O-ring is normally inside; tighten diagonally, the valve is installed. The valve needs to be cleaned when the initial pressure is too small when adjusting the shear angle.
