Reasons for Failure of Brake Machine Control System

When using the equipment such as a brake machine, when the machine maintains pressure, it will encounter the situation that the slider pressing force is insufficient and the return speed is slow. What causes this situation? According to the hydraulic system diagram and working process analysis, the reasons for the insufficient slider pressing force and the slow return speed during the pressurization of the bending machine may be as follows:

(1) The piston and end cover of the bending machine is not well sealed, and the bending machine causes serious leakage inside and outside the cylinder.

(2) The relief valve 14 is under pressure.

(3) The poppet valve 12 has a serious wear on the surface of the valve plug, causing the valve port to close loosely.

(4) The relief valve 9 is set to a low pressure.

(5) Excessive pressure in the hydraulic pump causes a low pump pressure.

(6) The surface of the spool of the reversing valve 6 is worn, which causes the spool to move in the valve body to be difficult, and the built-in one-way closing of the valve 11 is not strict or the gap of the valve surface of the valve body is too large.

The cause of the failure of the bending machine handling system is briefly introduced here for everyone today. When this happens, it can be based on the content explained in the article for actual operation and use, try to avoid problems in this area, take measures to avoid as soon as possible after the occurrence of problems, in order to better ensure the operation of the equipment.

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
