CNC Hydraulic Sheet Metal Press Brake Bending & Shearing Machine

Bending machine is able to do conventional plate bending processing, based on that, it can also complete much special processing, such as reaming processing after bending, groove treatment before bending, cutting holes or cutting lines alongside the bending line, using repair processing to make it to the design dimension at the edge of the hole after bending. When  press brake bending machine  doing reaming processing after bending, only one or a few pixels hole to the distance of the bending lines is less than the minimum spacing. When the need for product appearance is strict, in order to avoid material stripping when bending, you can treat the pixel with shrinkage, but there are many procedures to do and the efficiency is low. In actual design, because of the need for structural design, the processing factory usually adopts the groove treatment before bending because the actual distance is smaller than the above-mentioned distance. Since the numerical control bending machi...

When the aluminum plate bends, it can break easily, or when it is bent, it will burst through anodizing, and many of the sheet metal processing enterprises are confused, so how can we not break? First of all, we need to know the main reasons for the fracture of the aluminum plate and the following points: 1.Hardness of aluminum plate The aluminum plate is too hard and easy to break. This requires the selection of good aluminum, mainly aluminum plate number, and status. General 1 series, 3 series, 5 series are commonly used;  The hardness of 6 series and 7 series is too high, so it is easy to bend after annealing treatment to O state. And the quality of the aluminum. 2. Thickness of aluminum plate Too thick aluminum plate is not good to bend, use thinner aluminum plate as far as possible. 3. The size of bend R Angle The larger the Angle, the higher the success rate is, so the larger the Angle of R is. 4. Aluminum plate grain direction The bending d...

It's well-known that hydraulic press brake machine can only use bending mould for plate length bending processing, stamping die can only be used in  power press punching machine  as single mode, but if we can combine plate length bending and stamping die single molding effectively; For some products that are processed on line (such as profiles), it means that the production efficiency is several times higher. Substantial improvement in product quality; The sharp decrease in labor intensity. It has an inestimable effect on reducing the production cost. For the products of online processing, most of them are mainly punch holes. If we can make the bending machine similar to the punching machine, it will be better.  That is to make the press brake bending machine mold unloading workbench as workbench suitable for fixed stamping die, and as long as change the mould of the waste discharge to the back side (bottom row material for machine tool under the front board, is diffic...

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...

1. The noise of the oil pump is too loud (heating too fast) and the oil pump is damaged 1). The oil pump is absorbed by the oil pump suction pipe or the oil tank is too low; 2). The oil temperature is too low, the oil viscosity is too big, which causes the oil absorption resistance; 3). The oil filter is blocked and the oil is dirty; 4). Pump damage (pump installation injury) by any beat; 5). The installation of the coupling, such as axial tight, the motor shaft and the axis of the pump will not be on the line; 6). The duration of the test after the pump installation is reversed or not refueling; 7). The high pressure filter is blocked or the flow is not up to standard; 8). Oil pump suction (there is oil, but there is air at the oil pump suction mouth); 9). If it is a plunger pump, it may be that the height of the return oil outlet line is too low; 10). If it's HOEBIGER oil pump, then it might be gas; 11). The oil temperature is too high, results in the decrease of viscosity (60...
