In-Depth-How Hydraulic Press Brakes Work-KRRASS


The Hydraulic Press Brake includes a bracket, a workbench and a clamping plate. The workbench is placed on the bracket. The workbench is composed of a base and a pressure plate. The base is connected to the clamping plate through a hinge. The base is composed of a seat shell, a coil and a cover plate. The coil It is placed in the depression of the seat shell, and the top of the depression is covered with a cover plate. When in use, the wire is energized to the coil, and after energization, an attractive force is generated on the pressure plate, so as to realize the clamping of the thin plate between the pressure plate and the base. Due to the use of electromagnetic force clamping, the pressure plate can be made into a variety of workpiece requirements, and it can also process workpieces with side walls.

Hydraulic press brakes are the safest and more controllable than a mechanical brake. They generally allow for multiple speed settings. Hydraulic also allows for more precision bends, providing greater control when inching down and getting set for a job.

Hydraulic Press Brake Instructions

  1. First, turn on the power, turn on the key switch on the control panel, and then press the oil pump to start, so that you can hear the sound of the oil pump turning. (The machine does not work at this time)
  2. Stroke adjustment, the use of the bending machine must pay attention to the adjustment of the stroke, and it must be tested before bending. When the upper die of the bending machine goes down to the bottom, there must be a gap of plate thickness. Otherwise it will cause damage to the mold and machine. The stroke adjustment also has electric quick adjustment and manual fine adjustment.
  3. For the selection of the bending notch, generally a notch with a width 8 times the thickness of the plate should be selected. If you bend a 4mm sheet, you need to choose a notch of about 32.
  4. There are generally electric quick adjustments and manual fine adjustments for the adjustment of the back gauge, and the method is the same as that of the shearing machine.
  5. Step on the foot switch to start bending. Unlike the shearing machine, the bending machine can be released at any time, and the bending machine will stop when the foot is released, and continue to go down after stepping on it.

How Does a Hydraulic Press Brake Work?

A hydraulic press brake uses the power of a hydraulic motor to apply force onto the metal, compressing it into the die forming the shape. It is the shape of the die that determines the shape acquired with the metal bending process.

The Bending Device of a Hydraulic Press Brake

The bending device of a hydraulic press brake is a stamping process where the sheet metal is stamped into the mold or dies for casting the metal to the required shape. Sheet metal is fed into the device, which gets aligned onto the die. Then as force is applied, the metal is cast as per the shape of the die.

The Die of a Hydraulic Press Brake

The die is a crucial part of a hydraulic brake because the shape and strength of the die shape the metal. It is possible to cast almost any shape using the latest devices that come with standard and upgraded options for easy and customized shaping. For accuracy in the shaping process, hydraulic press brakes are also designed to be vibration-free.

Why Use a Hydraulic Press Brake?

Hydraulic press brakes can carry out an automated bending process, and the choice of many manufacturers looking for cost-effective bending processes. The precision of the bending is also exact. Moreover, as hydraulic press brakes are available in user-friendly formats, the operator’s ease of use allows for fast metal bending operations.
