The anti-theft door embossing hydraulic machine is usually a three-beam eight-column or frame structure, which is used for pressing explosion-proof door panels, anti-cast aluminum door panels, large-size aluminum doors, iron doors, and stainless steel door panels. The workbench is enlarged to press large-size door panels. . The anti-theft door embossing hydraulic machine has a variety of molds, which has good orientation and density retention, reliable operation, and convenient operation. It is composed of a three-beam, eight-column, six-cylinder structure or frame structure. The core electric uses Schneider, which is safe and reliable, and the wiring of the switchboard is clear. In terms of matching, customers can choose grating protection, heat dissipation device, PLC control system, etc. according to their own needs. Oil tank shot blasting, high-pressure vacuuming, and dough clearing are combined with three new technologies.

Anti-theft door embossing hydraulic press hydraulic system

The hydraulic system of the facade/door panel embossing machine consists of a hydraulic transmission and control system. It is mainly composed of an oil tank, oil pump, cartridge valve, cooling, filter, etc. The electromagnetic reversing valve is controlled by the electrical system to realize various actions of the press.

• Oil tank

The oil tank of the anti-theft door embossing hydraulic machine is a welded piece of steel plate. The surface and interior have undergone strict slag removal and pickling treatment. The edge of the fuel tank is higher than the cover plate to prevent the oil from leaking.

• Cartridge valve

BCV series cartridge valve assembly is adopted, with a simple and compact structure, fast response, small internal leakage, large flow, anti-pollution, convenient maintenance, and long service life.

• Pressure gauge

The facade/door panel embossing machine uses an anti-seismic oil pressure gauge, which has high display accuracy and is not easy to be damaged. The electric contact pressure gauge detects the pressure in the upper chamber of the main cylinder at all times and stops pressing when it reaches the set pressure, realizing the constant pressure return.

• Pressure safety

The cartridge valve itself has a pressure adjustment system, and the pressure exceeds the set value to overflow and return to oil. Keep the system within the set pressure at all times to achieve over pressure protection.

Safety protection measures for anti-theft door embossing hydraulic press equipment

(1) Stationary and emergency stop buttons:

When an abnormality occurs, press the “Static” button, and all the work of the anti-theft door embossing hydraulic press will stop. Press the “Emergency Stop” button, including the motor.

(2)  Two-hand operation button:

The downlink synchronization time limit of both hands is 0.5~1S.

(3)  Slider locking device:

When the main slider of the anti-theft door embossing hydraulic machine is in the upper position, press the lock button to automatically lock the main slider. When the main slider is not in the upper position, press the lock button, and the slider will rise to the upper position first, and then lock automatically. When the main slider is locked, press the release button to automatically unlock.

(4)  Hydraulic double support insurance circuit:

To prevent the slider from descending out of control, a hydraulic support safety valve circuit is set in the lower chamber of the piston main oil cylinder to ensure safety. Set up a hydraulic interlock circuit to ensure that when the support safety valve is not opened, the upper chamber of the master cylinder cannot be pressurized.

(5) Liquid level alarm:

The oil tank of the explosion-proof door facade/door panel embossing machine is equipped with a liquid-level alarm device. The liquid level alarm is divided into two situations: super-normal working liquid level and low liquid level; In the super-normal working liquid level alarm, the yellow light is on, and the fuel tank should be replenished at this time. The oil reaches the normal working level; if the liquid level is too low, it will alarm, the red light will be on, and the press will stop working; at this time, the oil tank must be replenished to the normal working level before the machine can start to work.

(6) Overload protection:

There is a hydraulic safety valve in the hydraulic system of the anti-theft door embossing hydraulic press to ensure that the press will not be overloaded and damaged.

(7) Photoelectric protection device:

The explosion-proof door facade/door panel embossing machine is equipped with photoelectric protection devices at the front and rear to prevent operators from entering the work area when the slider is running.

(8) Wrapped joints:

Winding joints are added between the filling valve and the filling cylinder, and between the oil return of the main cylinder and the oil tank to reduce vibration.
