CNC Hydraulic Sheet Metal Press Brake Bending & Shearing Machine

1.  The work principle and usage The working mechanism of GLDMA  mechanical power press machine  is the crank connecting rod working principle. With this rigid mechanism, so the slider movement is forced and the number of slider stroke per minute and the motion trail of slider is fixed.Mechanical press is popularly used for sheet stamping, and it is also suitable for shearing, punching, blanking, bending and slight extension. The machine's body can be tilted so that the finished products and scrap material will slide from the mold. Automatic feeding devices can connect with power press, so it's easy to realize semi-automatic work. 2. Lubrication for mechanical press The press adopts distributed lubrication way: the lubrication points are on the left side of the crankshaft bearing, connecting rod, and the guide bushing quality parts on flywheel. User should add oil on each lubrication point before starting the machine. It is necessary to pay attention ...

1. Using compressed air as the power source, efficient and easy to operate, simple structure and minimal maintenance. 2. Less noise than traditional power press, it can save power consumption and reduce production cost. 3. Adjustable height, speed, stroke, pressure and stamping time according to different products or mould. 4. Equipped with anti-rotation guide bar, guide plate, high precision, can adapt to high-speed precision blanking. 5. Use both hands control or pedal mode to ensure the safety of operators. 6. With microcomputer control system, the mode can be manual, semi-automatic and automatic. 7. The heating mould, temperature control and pressure sensor can be optional. 8. The structure is simple and adopts pneumatic technology, so that an air compressor can be used for the work of multiple pneumatic punching machines, which can be more energy saving than electric punch. The operation of  pneumatic punching machine   is simple, the safety is high, adopt foot swit...

1. Maintenance of  power press machine A, Always keep the center column, the sliding block guide column clean, and the die bottom of the die when the die is kept clean, to ensure that the platform is clean and avoid scratches. B, The new machine after one month running, flywheel  should add butter (including feeder), if did not add some butter after longtime can cause the flywheel internal wear, impact the performance of the machine tool, every time after maintenance also need to add butter (high temperature above 150) C. Replacement of cycle oil of the machine table: the new machine shall be replaced within one month, and every other half of the year shall be replaced every six months to ensure the normal operation and precision of the machine tool (32 # mechanical oil or mobil 1405 #). 2. Operation safety of power press punching machine A. Can't operate A machine at the same time, otherwise it will cause the machine to start suddenly and cause damage to the operator. ...

What is the difference between a high speed punch machine and a power press machine? Mainly in the precision, strength, speed, system stability and construction operations, such as the general punch than the good, and high requirements. But not the high speed punching machine is better than power press machine, the specific purchase also depends on the application, if the stamping speed under 200, the choice of power press machine is still relatively affordable. The following is to explain the main difference between high speed punching machine and  power press machine . 1. Speed Power press machine speed is below 110~200 times High speed punching machine is usually more than 200~1100 times 2. Fuselage material High-speed punching machine fuselage materials using high-grade, high-strength cast iron and stress tempering and natural aging treatment, the structure of the use of the integration of special cast iron alloy, high rigidity and seismic resistance, to ensure that its deforma...

Power press machines or punching machines are the most important metal shaping tools. When it comes to the bulk metal shaping and forming tasks for industrial requirements, power press punching machines are widely preferred. It is actually an advanced and a powerful sheet metal equipment that can cut, press, bend and form sheet metal into different shapes and sizes, used for bulk production from cold working of ductile materials like mild steel with rotating flywheel acting as energy storehouse to operate ram to impact on the workpiece. It is used to operate various functions with bed, plate, bolster and ram. Knock out mechanism is used to eject the furnished work piece from power press. Proper cushioning must be there beneath the bolster, when heavy effect is given to the workpiece. There are different types are available in the market such as c type and pillar type for sheet metal machining work in manufacturing industry.  C type power press machine  is designed in such...
