Common Failure and Elimination of Hydraulic Pump in Bending Machine

The hydraulic components of the dispersed bending machine are connected by oil pipes and pipe joints to form a complete hydraulic system. The performance of tubing and the structure of pipe joints are directly related to the working state of a hydraulic system. This article introduces commonly used hydraulic tubing and pipe joints, and the general name of tubing and pipe joints is bending machine hydraulic pump.

I. Oil pipe of bending machine

In the hydraulic system of the bending machine, there are many types of tubing is used, such as steel pipe, copper tube, nylon tube, plastic pipe, rubber tube, etc.,. In the selection of hydraulic system pressure, the position of hydraulic components and the working environment of the hydraulic equipment should be taken into consideration.

1. The steel pipe is divided into two types: seamless steel pipe and welded pipe. The former is usually used in high voltage system, and the latter in low voltage system. The characteristics of the steel pipe are high bearing capacity, low price, high strength and good rigidity, but it is difficult to assemble and bend. At present, steel pipes are the most widely used in all kinds of hydraulic equipment.

2. Copper tubes are divided into two types, brass and copper tubes. The copper pipe has the advantages of convenient assembly and easy to bend, but also has the disadvantages of low strength, poor anti-vibration ability, high material price, easy to make hydraulic oil oxidize and so on. It is generally used in the inner place or the place where the pressure system is 0.5-10MPa's medium and low-pressure system which makes it difficult to assemble in the hydraulic device.

3. Nylon tube is a new type of semi-opaque tube, which has two kinds of pressure bearing capacity, 2.5MPa, and 8MPa. Nylon tube has the advantages of low cost, easy bending as well as the disadvantage of a short life. The low boat systems are often used as a substitute for copper tubes.

Fiber Laser Cutting Machine

Nowadays laser cutting machine is more and more widely used, as it is with high speed, high precision and automation. It can save manpower and improve production efficiency. The laser is shot from laser generator, through optical system, focus to high power and density laser beam. The beam shoots on surface of workpiece and makes it reach melting point or boiling point, at the same time, the high pressure gas which is on the same axis with laser beam blow the melting or pneumatolytic metal away. That is the basic reason of laser cutting. According to the laser generator, there are two types – CO2 type & fiber type. The frequency of the CO2 laser requires higher wattage of lasers to penetrate through metals. CO2 laser systems are best suited to cutting wood, acrylic, plastic, and fabric. Fiber laser cutting machine is much more energy saving. In the situation that reaches same performance, whole fiber cutting can save around 70% energy than CO2 type. The wattage can range from 50

How to Adjust the Clearance of Upper and Lower Blades of Hydraulic Guillotine

To many customers, they can easy to get how to adjust the clearance of upper and lower blades of small model hydraulic guillotine shearing machines . How every, it's do hard for them to adjustment big models like QC11Y-40*2500 mm or QC11Y-40*3200mm. It is an important factor that affects the cutting quality and prolongs the service life of the blade. The correct adjustment of the blade thickness depends on the shear plate thickness. The machine tool converts the blade gap value to the plate material value directly on the gap dial. The clearance between the upper and lower blades of the shear should be the same throughout the entire length. This shear shall be equipped with a supplementary tool holder on the worktable to be used as a micro adjustment of the uniformity of the gap between the upper and lower blades. The minimum clearance before adjustment is 0.05 mm at the factory. The user should not change easily during normal use. After the blade is used for a certain period of

6mm Hydraulic Shearing Machine With Estun E21s

6mm is a common thickness in sheet metal manufacturing. 6mm hydraulic shears is also a popular size in shearing machine. GLDMA can offer 6mm*2500mm, 6mm-3200mm, 6mm*4000mm, 6*5000mm different sizes of worktable, to satisfy variety of plate cutting demands. GLDMA Q12K series swing shearing is standard with Estun E21s system, which can control backgauge and the ordinary motor or frequency converter. Finished parts count and 40 program store functions can support common cutting task much more continuous, so that improve daily producing efficiency and save labor cost. There are also other advanced shearing machine controller to choose, like Estun E200ps, Delem DAC 310s. E200ps can realize servo control on X axis (backgauge), the cutting speed and precision are in a higher level. DAC 310s is with control of blade clearance, and the program storage is improved to 100 steps each. Client can choose the suitable model based on their own requirement and budget. 6mm hydraulic shearing usual
