4, Performance and characteristics:

This machine has an independent power mechanism and electrical system, and adopts centralized button control. The process actions are manual and semi-automatic control. The hydraulic system adopts integrated plug-in valves, with a compact structure, sensitive and reliable action. Fast speed, low energy consumption, and low noise. The working pressure and travel range of this series of products can be adjusted according to work needs.

5, Structure Overview:

This machine consists of two main parts: the main engine and the control mechanism, which are connected through oil pipelines and electrical devices to form a whole. The main engine includes the body, main cylinder device, etc. The control mechanism consists of a hydraulic pump station, an electrical box, a mobile control console, etc. The structure and functions of each part are described as follows:

1)machine body

The body of this machine adopts a three beam and four column structure: it is composed of upper crossbeam, slider, workbench, main cylinder, hydraulic pad, column, control system, and electrical system components.

2) Master cylinder

The main cylinder block is fixed to the table, and the lower end of the piston rod is connected with a flange, bolt, and slider. The piston head is divided into two oil chambers with YX type sealing rings in opposite directions. The outer circle of the guide sleeve is equipped with an O-ring, which is locked with the flange and bolt to ensure the sealing of the cylinder port. Install a dust ring on the cylinder flange to ensure dust prevention of the piston rod.

3) Range limiting device

The limit device is installed on the right side of the machine and is mainly used to control the stroke distance of the slider. It consists of pad iron, contactless travel switch, etc.

4) Hydraulic station

The hydraulic pump consists of an oil tank, an axial piston pump, an electric motor, a two-way plug-in valve, a high-pressure self sealing oil filter, and an air filter, installed on the right side of the machine.

The fuel tank is made of Q235 steel plate welded components, and a pressure gauge is installed at the front end for observing the pressure. Install a level gauge in the oil tank to observe the oil level. A high-pressure self sealing oil filter is installed at the suction port of the oil pump to ensure the cleanliness of the pump and hydraulic system. An air filter is installed on the panel of the fuel tank, and the upper cover can be opened for refueling.

5) Axial piston pump

This hydraulic system adopts YCY14-1B axial piston pump. The instructions can be found in the user manual of the axial piston pump, and there is no overview here.

6) Two way cartridge valve

Its structure mainly consists of plug-in parts, control cover plates, pilot control valves, and integrated valve blocks,

a. The plug-in component consists of a valve insert, a seal, a valve body, etc. It can be a cone valve or a spool valve structure. Its main function is to control the direction, pressure, flow rate, etc. of oil flow in the oil circuit.

b. The control cover plate is composed of various micro pilot control components and other hydraulic components embedded in the cover plate. The main function is to fix the plug-in components. The combination of various embedded micro pilot control components and pilot control valves can control the working status of the plug-in valve. The control cover plate is divided into directional control cover plate, pressure control cover plate, and flow control cover plate.

c. The pilot control valve is installed on the control cover plate to control the action of the plug-in electromagnetic directional valve, and its components are electromagnetic directional valves.

d. The integrated valve block is used to install plugins, control covers, and other control valves, and to communicate with the main and control oil circuits.

6, Overview of hydraulic system

The hydraulic system consists of energy conversion devices (oil pumps and cylinders), as well as energy transfer devices (oil tanks, oil pipelines), etc. With the help of electrical system control, drive the slider to complete various action cycles.

7, Electrical control system

1. The machine is equipped with an independent electrical control box, which can move both sides of the equipment freely, and centralized buttons control the operation of the entire machine.

8, Operating System

1) It has two operation modes: inching and semi-automatic, and two process operations: fixed stroke and constant pressure.

2) The slider stroke is adjusted by a contactless switch control device.

3) The main cylinder pressure is adjusted by the pressure regulating valve.

4) The pressure holding time can be freely set
