六、Structure and performance

This hydraulic punch press is a utility model patented punch press developed and produced by our company through years of experience in punch press production and the introduction of advanced foreign technology. It replaces the traditional mechanical punch press, which relies on the inertia of the flywheel to provide rigid stamping through the rotation of the crankshaft, with flexible stamping provided by the hydraulic system, and effectively solves the problem of hydraulic rapid stamping technology, making it a true hydraulic punch press.

Main features: stable and safe, silent and environmentally friendly, widely practical, easy to operate, easy to control, beautiful workpiece, compact structure, energy-saving and emission reduction. The specific introduction is as follows:

1. The hydraulic punch press is stable and vibration free during stamping, safe to operate, and not prone to work-related accidents. The power system is equipped with an overflow protection device, which is not easy to damage the body parts and molds, greatly improving the safety performance of the equipment.

2. Hydraulic punching machines do not have flywheels and cranks, resulting in low noise during operation and environmental friendliness, greatly improving the working environment for employees.

3. The hydraulic system of the punch press has adjustable working pressure and provides flexible punching force for different mold workpieces. The slider adopts advanced six sided guide rails with high precision. The punched workpiece is less prone to cracks, and the processed workpiece is more precise and aesthetically pleasing.

4. Hydraulic punching machines can easily adjust the stroke and starting position of the stamping slider, and adjust the stamping speed for different mold workpieces to achieve fast and efficient stamping production.

5. Hydraulic punching machines equipped with different molds can perform punching, cutting, corner cutting, rolling, stretching functions, and can also be used as bending machines with bending knives. This punching machine is versatile and widely applicable.

6. The control system is equipped with automatic, semi-automatic, and jog modes. The automatic mode can continuously process the strip material, while the semi-automatic mode can batch process the gear positions. The jog gear allows the stamping slider to stay in any position. When installing the mold, it is convenient, fast, accurate, and safe to align the mold up and down. When operating the stamping, the line can be viewed to accurately press the single piece. The whole machine is extremely flexible and easy to use.

7.The hydraulic system of the hydraulic punch adopts flexible electrical control and is equipped with PLC, which is easy to achieve linkage and automatic control with peripheral equipment such as automatic feeding mechanism, facilitating automation and assembly line production.

8. Hydraulic punching machines do not have a huge body and flywheel, and the welded body structure of the whole machine is compact. Punching machines with the same punching pressure occupy less space, consume fewer castings, and do not have the energy consumption and pollution caused by secondary casting, greatly reducing enterprise consumption and social resources, achieving the effect of energy conservation and emission reduction. The mechanical components are stable and reliable, and the equipment operates with fewer malfunctions for a long time.

9. The hydraulic punching machine adopts the C-type throat frame of the standard punching machine, with T-shaped grooves on both the upper and lower workbenches, and mold holes on the bottom of the slider, which can make various traditional punching machine hardware stamping molds universal. Adopting motion buttons and foot pedal control without changing employees' operating habits. The whole board machine has no processing dead corners, making it the preferred punching machine for large-scale sheet metal stamping processing.

10. The main cylinder body is fixed to the upper part of the machine body by the cylinder shoulder and the large locking nut. The lower end of the piston is connected to the slider with a connecting flange and bolts, and the piston serves as a guide. The piston head is equipped with YX type sealing rings in opposite directions, and an O-ring is installed on the piston rod. The cylinder is divided into two oil chambers, and a guide sleeve is installed on the cylinder. The outer circle of the guide sleeve is equipped with an O-ring, which is locked with flanges and bolts to ensure the sealing of the cylinder mouth. A dust ring is installed on the cylinder flange to ensure dust prevention of the piston rod.

七、 Machine tool electrical system

The overview of the electrical control system of this machine is as follows:

Main power supply: 380V, 50Hz, three-phase, control power supply: 24V. The main circuit and motor are both equipped with automatic switches for short-circuit protection and overload protection. The control circuit adopts fuses for short-circuit protection. The main components of the machine are reliably grounded.

八、 Hydraulic system

The hydraulic system consists of energy conversion devices (pumps and cylinders) and energy transmission devices (oil tanks, pipelines). With the control of the electrical system, the slider is driven to complete various action cycles. The hydraulic system adopts high flow plug-in valves, oil tank with oil level display, filter element and other devices. The fuel tank is a welded steel plate structure, and there are screw plugs at the bottom for draining and draining oil.

In order to prevent the slider from losing control and descending, the machine is equipped with a hydraulic support safety circuit. A hydraulic support safety circuit is installed in the lower chamber of the piston type main cylinder to ensure safety.
