(Puerto Rico hydraulic punch cylinder,produced by Hebei Hengyu company）

hydraulic punch cylinder are widely used in Puerto Rico，because of excellent fatigue and impact resistance，excellent fatigue and impact resistance，simple structure and reliable operation.So our company has designed hydraulic punch cylinder for customers from Puerto Rico.

Introduction to hydraulic punch cylinder:

In recent years, the processing process of the hydraulic punch cylinder generally adopts the rolling method, which is a pressure finishing processing, which uses the cold plastic characteristics of the metal at room temperature, and uses the rolling tool to exert a certain pressure on the surface of the workpiece, so that the surface metal of the workpiece produces plastic flow, and fills in the low concave trough of the original residue, and the roughness value of the workpiece surface is reduced. Due to the plastic deformation of the rolled surface metal, the surface tissue is cold hardened and the grain is fine, forming a dense fiber, and forming a residual stress layer, and the hardness and strength are increased, thus improving the wear resistance, corrosion resistance and compatibility of the workpiece surface. Rolling is a plastic machining method without cutting.

The scar on the sliding surface of the hydraulic punch cylinder piston will transfer with use. Before the piston is installed, there are scars on its sliding surface, which are installed intact and untreated, and these scars will in turn scratch the inner surface of the hydraulic punch cylinder wall. Therefore, before installation, these scars must be fully repaired.

If the piston rod and hydraulic punch cylinder are stuck or the hydraulic punch cylinder is blocked, at this time, no matter how to operate, the hydraulic punch cylinder does not move or has little action. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the hydraulic punch cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

When purchasing the hydraulic punch cylinder, try to clarify the following parameters of the hydraulic punch cylinder: A. hydraulic punch cylinder diameter, rod diameter, stroke; B. Working pressure or hydraulic punch cylinder load; C. Working environment temperature; D. Working medium; E. Operating speed; F. Other parameters, such as connection form, mounting size, etc. In this way, the right hydraulic punch cylinder type can be found accurately and quickly.

Answers to some questions about hydraulic punch cylinder:

Is there a way to make the cylinder stop pushing when it hits something hard during the process of pushing?
The simplest solution is to press the stop switch, this switch has a mechanical type, touch the object on the action or send a stop signal, through the operation of the motor control cylinder; There is also an induction switch, that is, when the hydraulic cylinder expands to the range of the induction switch can sense the signal, it sends a signal to let the motor act, resulting in the corresponding action of the cylinder.

When the cylinder is tested, why can't the pressure be maintained with the balance valve?
Because the oil into the oil chamber through the hydraulic lock on the control oil circuit through the other side of the spool, the original valve is designed in this way. It locks the circuit after the oil supply circuit loses pressure, on the contrary, if you keep supplying pressure, it is always in the state of opening the other side of the one-way spool. So this valve can't be used in the test.
