Hydraulic Shearing Machine Failure

Hydraulic Shearing Machine Failure：

1. Can the crescent curve be avoided when the plate shear is used to cut the plate?
For the shearing of sheet metal, if the shearing machine is used, there will be crescent bending. Moreover, from the current point of view, it is inevitable. The greater the thickness of sheet metal or the smaller the width of strip, the more serious the problem. However, some measures can be taken to minimize, such as selecting the upper and lower circular blades, or supporting the sheared sheet after separation.
2. On the shearing machine, when one foot is stepped down, if the knife doesn’t come up and makes a strange noise, what’s the reason?
As for the specific cause of the failure of the plate shears, Wuxi Shenchong Machine Tool Co., Ltd., the manufacturer, thinks that the main reason is that the upper and lower edges of the plate shears are jammed by materials, resulting in blockage and other problems. At this time, if it is not solved in time, the motor in the plate shearer will be blocked, and then it will be damaged or damaged. Therefore, we should pay attention to it and deal with it in time without delay.
3. In hydraulic plate shears, if the nominal pressure is 12500kn, what does it mean? In addition, how to judge the quality of hydraulic pendulum shear?

If the standard of the nominal pressure of the hydraulic shear is 12500kn, it means that the pressure of the shear is 125t. And the hydraulic pendulum shears this kind of shears, its good or bad judgment, mainly depends on whether the equipment operation is normal, as well as in the purchase, to see the manufacturer and price of these two aspects, so as to make a judgment.

1. If the nitrogen cylinder is used in the shearing machine, what is the pressure?
Anhui YONGYA in the use of plate shears, the use of nitrogen cylinders, its operation, is to find the nitrogen cylinder on the interface, and then connect with a high-pressure pipe, after that, is to open the valve on the bottle, until the pressure is 6 to 7 MPa. At this time, close the valve and stop using the nitrogen cylinder. So, the pressure is 6 to 7 MPa.
2. Is there any difference between shearing carbon steel and stainless steel with plate shears?
Shear, its shear of carbon steel and stainless steel, is different, although these two are metal materials, but in strength, is stainless steel to larger. Therefore, reflected in the shears, for its same equipment, is the specification of carbon steel, can be larger.
3. Can the clearance between the upper and lower knives of the hydraulic swing shear be adjusted by the mechanism?
The clearance between the upper and lower knives of the hydraulic swing shear can be adjusted through the mechanism. Specifically, it is to adjust the operating mechanism to adjust the clearance size. However, to be specific, we have to look at the process requirements and material types, because if the quantity is different, then there are different gap ratios.
