How to distinguish between hydraulic cutting machine and mechanical transmission cutting machine?


The main basis for judging the function of the honggang hydraulic cutting machine is: the size of the punching force and the punching speed. The punching force is very big, but the punching speed is very low, or the punching speed is very high, but the machine with very small punching force cannot successfully complete the punching task.

The mechanical cutting machine generally has a high punching speed of about 250 blows per minute; the punching speed is variable and the average punching speed is 200 mm/s. The cutting speed of the hydraulic cutting machine is generally greater than 110 mm/s.

Honggang hydraulic cutting machine is characterized by: When the upper platen through the mold action on the workpiece at a moment, the pressure within the role of the cylinder does not reach the rated pressure, the pressure will increase with the contact (cut into the work) time, until the electromagnetic The reversing valve receives the signal, the reversing valve changes direction, and the punching head starts to reset; at this time, the pressure in the fuel tank may not reach the set rated pressure value due to the limitation of the time of the pressure oil entering the fuel tank; The system pressure has not reached the design value, and the punching has been completed.

The mechanical drive cutting machine and the hydraulic drive cutting machine are different, mainly determined by the different characteristics of the two types of transmission: the mechanical transmission is a rigid transmission, and the hydraulic transmission does have a certain degree of flexibility.
