Rows of steel pipe electric permanent magnet lifting spreaders, ultimately choose QHMAG
2021-07-27
The QHEPM-1000 row steel pipe hoisting electrical permanent magnet lifting spreader control system designed and produced by Hunan Qianhao Electromechanical Technology Development Co., Ltd. has recently passed user acceptance and passed nearly half a month’s trial operation. The use effect is good. The user gave It is highly rated.     This set of electric permanent magnet lifting spreader system is used in the 168 project team of a well-known large steel pipe manufacturing enterprise in China. The electric permanent magnet imported from Italy has too little suction force and often hangs the pipe phenomenon, and the controller often burns components, so the user Want to carry out the localization transformation, the customer through the preliminary technical exchanges, on-site inspections, business negotiations, and finally decided to implement the transformation by our company.     The relevant technical parameters of the steel pipe are as follows: Carbon content: 0.15~0.5% Steel pipe temperature: not more than 60℃. Outer diameter of steel pipe: Φ32~Φ180mm, wall thickness: 2.5~25mm Unit weight per meter: 16.6~163.8kg/m Center distance of tube row: up to 880mm   The technical index of the electric permanent magnet hoisting sling body Model: QHEPM-1000 Rated voltage: DC170V Working current: 32A Excitation and demagnetization time: both less than 1 second A working cycle: about 15 to 18 seconds Dimensions: 924 X 312 X 110 (mm) Using magnetic shielding technology to ensure that there is no magnetic force outside the magnetic poles Residual magnetic force after demagnetization

Advantages of choosing electro magnetic chuck for machine tool processing
2021-07-27
Advantages of choosing electro-permanent magnetic chuck for machine tool processing fixtures: Strong magnetic force, high processing precision, safety, strong, energy saving, environmental protection   Among the magnetic chuck, the demand for permanent magnet chuck is currently increasing the fastest. This is because it uses an electromagnet to control the switch of the permanent magnet that produces the attraction force, and does not need to be continuously energized. Because it can open and close the magnetic circuit only by instantaneously energizing the built-in coil, the suction and removal of the workpiece can be operated by a switch. In addition, because the suction force can be maintained even in the event of a power failure or disconnection, the safety of use is ensured, and because there is no magnetic force change or power failure, the workpiece can be accurately fixed. At present, due to the improvement of the magnetic circuit, the attraction is enhanced, so the permanent magnet can be used to fix large workpieces, and the processing of bars or special-shaped workpieces is also very easy. Due to these advantages, its use is expanding day by day.   Electric permanent magnetic chuck application equipment: CNC machining center (CNC), boring and milling machine, special machine tool, etc.   Application fields of electro permanent magnet chuck: Mold processing, auto parts processing, hardware processing, etc.
