Use of hydraulic shearing machine

The reason for the collapse of the CNC shearing machine is a situation we often encounter in our work. Why does the shearing machine appear to collapse?

Why does the CNC shearing machine appear to collapse? What should be paid attention to during the use of hydraulic shears?
High-speed shears are used in many machining processes. In the process of use, due to the unreasonable operation of many friends, the phenomenon of tool chipping often occurs. Generally, it is easy to cause the collapse of the mouth, which may be caused by some of the following reasons.

First of all, it may be that the cut sheet is too hard. We need to pay attention to this in the operation process. We can’t cut all materials with a knife, otherwise it will easily lead to chipping. If you encounter a very hard material, we must change to a more suitable blade. Maintenance is very important, otherwise the best blade will not last long after it reaches your hand.

Secondly, when cutting the plate, we also need to carefully adjust the gap of the knife edge, otherwise it will easily lead to chipping.

Again, when cutting round steel, it is most likely to cause cracks. If it is this material, we need to be extra careful.

Anhui Yongya thinks that the quality problem of the blade itself may in the end. We must not choose a blade of poor quality for cheap. After all, this is a very important part of the shearing machine.

Matters needing attention in the use of hydraulic shears:
1. Start the shearing machine for a few cycles of idling to ensure that under normal conditions, test cuts of different thicknesses, from thin to thick. Ensure that the user is familiar with the performance of the shears.

2. Different blade gaps must be adjusted for different plate thicknesses during trial cutting. If the corresponding blade gap is not adjusted, the durability of the blade will be affected.

3 The shearing machine turns on the pressure gauge switch during the cutting process and observes the pressure value of the oil circuit. The pressure should be less than 20MPa when cutting a 12mm board. This remote pressure regulating valve No9, the pressure is set to 20-22MPa when leaving the factory, the user must abide by this regulation, and shall not increase the pressure for cutting the material surface beyond the specified material and cause damage to the machine.

4. Sound balance during operation. If there is noise in the shearing machine, stop and check.

5 When the shearing machine is operating, the temperature of the fuel tank rises <60 degrees. When it exceeds, it will shut down and rest.
