CNC Hydraulic Sheet Metal Press Brake Bending & Shearing Machine

For sheet metal fabricators, this sheet metal weight calculation formula will help you to make the right decision in production. As one of the largest  sheet metal fabrication machinery  manufacturers from China, Gldma make insistent effort in the development and production of high quality sheet metal processing tools, as well as the constant knowledge updates for engineering. sheet metal bending, cutting, shearing As below, there are listed 14 general steel materials: Steel Plate, Steel Tube, Round Steel, Square Steel, Flat Steel, Hexagonal Steel, Rebar, Flat Steel Tube, Rectangular Steel Tube, Equal-leg angle Steel, Unequal-leg Angle Steel, Brass Tube, Copper Tube, Aluminum Embossed Sheet. General Steel Formulas:  1. Steel Plate Formula: 7.85×length (m)×width (m)×thickness (mm) Formula: 7.85×length (m)×width (m)×thickness (mm) E. g: 6m (length)×1.51m (width)×9.75mm (thickness) Calculation: 7.85×6×1.51×9.75=693.43kg 2. Steel tube Formula:...

For the perfect manufacturing sheet metal fabrication machinery, GLDMA have  4 sets of large-sized floor-type milling& boring machine , one is 20 m length, one is 16 m length, the other two is 12 m length; 4 sets of over 3 axis  CNC machining  center; 1 set of ultra-large type annealing furnace which is the only one in a local place.

The common malfunction of electric- hydraulic press brake  and solutions 1. Slide can't move down quickly  The poppet valve is not connected and the spool is stuck  The spool of the directional valve which controls filling valve is stuck, can't be reset  The orifice of the filling valve is blocked  The proportional valve is abnormal  The mechanical part is too tight 2. There is large synchronization error between two cylinders when slider quick moves down  There is large friction difference between the two guide rails  There is large friction difference between the two cylinders  The connection between one cylinder and slider is skew, radial force  Check whether the damping in the filling valve control port which is on synchronous block is blocked  Check whether the filling valve is stuck  Check whether the cylinder, slider is too tight  The proportional valve is abnormal 3.The system does not build ...

Electro-hydraulic Servo Press Brake , most clients will feel confused of this name. What is that? Actually it's a kind of totally CNC press brake machine. This bending machine consists of machine rack frame, slider, work table, cylinders, hydraulic proportional servo system, position detection system, CNC system and electrical control system and other components. It's a kind of high precision, high efficiency sheet metal processing equipment. The slider up and down movement is driven by the left and right two cylinders. Relying on the mold respectively on slider and work table, the sheet metal can be bent into different angles or cross-sectional shape. During the movement of the slider, two grating scales mounted on each side of the machine detect the position of the slider at both ends in real time.  On the one hand, comparing the two values, according to controlling the proportion of servo to correct bias timely, in order to maintain the slider parallel. On the other hand...

The adjustment of blade gap of  hydraulic shearing machine  is an important factor to influence the shear quality and prolong the life of the blade. When the gap is adjusted, the lock screw will be released and then turn the handle to the required calibration value to lock the screw again. The ball valve shall be used to measure the evenness of the blade gap between the upper and lower blades. The specific method is a single trip, when the upper and lower racks to the lower dead point, that is, quickly turn the ball valve to close the oil road, so that the upper tool rest stops at the bottom dead point. Then, the micro open and closed ball valve is continued, and the upper tool holder is increased on the whole trip, and the clearance of the blade gap can be measured at this time. 1. Clean the oil stains on the surface of each machine, and notice that the cutting line on the cut-off valve should be in the open position. 2. The lubricating grease is injected into the oil t...

When doing sheet metal processing, the main process is bending, the main machinery is hydraulic press brake. Bending seems simple, but there are many means and tricks in it. The following is to introduce the various bending techniques of sheet metal bending. Tool Graphics software CAD Method and Steps: 1. The general bending 1:(R=0, θ=90°) L=A+B+K 1.
