Disadvantages of hydraulic press brakes and their price considerations

The press brake is a widely used bending machine that has long been hydraulic. So do you know what are the disadvantages of hydraulic press brakes and what factors need to be considered in the price? The following world press machine will give you a brief introduction.

Disadvantages of hydraulic press brakes:

1. Interface signal inspection: By checking the interface signal of the machine tool control system with the programmable hydraulic press brake controller, and comparing it with the correct signal in the interface manual, the corresponding shortcomings can also be found out.

2. Instrument measurement: When there is a defect in the hydraulic bending machine system, use the conventional hydraulic bending machine electrical testing equipment, tools, and measure the voltage, power supply, pulse signal, etc. with some defects according to the system circuit diagram and machine tool circuit diagram to identify the defect address. If the input voltage of the power supply exceeds the limit, the power supply monitoring can use a voltmeter to measure the network voltage, or use a voltage tester to monitor in real time to avoid other reasons. Oscilloscopes can be used in the event of faults in the azimuth control loop of the hydraulic bending machine.

3. Use the programmable controller to analyze the PLC intermittent situation: when the programmable controller has a defect, the reason for the interruption is recalled by the method of interrupting the warehouse. Using the hydraulic bending machine programmer can call out the intermittent warehouse and block warehouse under the condition of system interruption, and find out the fault address according to the reason indicated by it.

Price considerations for hydraulic press brakes:

1. For the parts that need to be produced, the point is to buy a machine that can complete the processing task with the shortest workbench and the smallest tonnage.

2. Material grade. Compared to mild steel, stainless steel typically requires around 50% more load, while most grades of soft aluminium require around 50% less. You can always get a tonnage table from the hydraulic press brake manufacturer that shows an estimate of the tonnage required per foot of length for different thicknesses and materials.

3. When free bending is used, the bending radius is 0.156 times the opening distance of the die. During the free bending process, the opening distance of the die should be 8 times the thickness of the metal material. If the bending radius is smaller than the material thickness, a punch with a front-end fillet radius smaller than the material thickness must be used, and the imprint bending method must be resorted to. In this way, 10 times the pressure of free bending is required.

The above is the introduction of the world press machine, I hope it will be helpful for everyone to understand the hydraulic press brake.
