How to solve the heating problem of hydraulic system of CNC plate shears

CNC plate shears also need to do a good job of inspection before work, sometimes we may be in use when the lack of oil, this is we did not follow the instructions, regularly for it needs to get lubrication parts of oil.

Then, check the place where the bolt is installed to see if the bolt connection is tight. If the blade is connected with the slider, the blade is connected with the lower worktable, and the connection between the lower worktable and the machine body of the CNC shearing machine is loose. Check whether the blade clearance is adjusted to the most suitable position. Blade can be said to be the soul of the shearer, whether it can cut, whether it can cut well is closely related to it.

In order to get the best start-up parameters, it is necessary to repeat the test in the commissioning stage of the soft starter of the hydraulic shearing machine, which will greatly increase the start-up times, which inevitably leads to the overheating of the soft starter

1. The cooling fan of the electric control cabinet of the soft starter of the hydraulic shearing machine should be running all the time, so that the power thyristor in the soft starter can dissipate heat smoothly and reduce the junction temperature.

2. There should be a 10-15 minute interval between each start of the shearing machine, so as to cool down the power thyristor in the soft starter, so as to avoid the soft starter alarming due to overheating.

3 in the hydraulic system with hydraulic oil as the force transmission medium, the flow velocity of each part is not the same in the process of hydraulic oil flow, which makes the internal friction in the oil cylinder, and then leads to the steady rise of the hydraulic system and the "heating" fault.

"Heating" is an inherent feature of hydraulic system, which can not be eradicated. As long as the temperature is kept under a certain threshold, it will not affect the service life, so it is mainly controlled. The use of high-quality hydraulic oil, hydraulic pipeline layout as far as possible straight line, pipeline accessories, valves can maintain a big brand.
