Working principle of press brake Fix the top punch and bottom die on the upper and lower worktable,utilize the relative motion of the worktable driven by hydraulic transmission as well as the shape of punch and die,to achieve the bending formation for sheet metal materials.Press brake composition

The concept of punching designates a slitting process in which a sheet is severed in one stroke. Shapes such as round holes are created in the part, and external contours are cut with single strokes.A punching machine works like a hole punch for paper. The punch presses the paper against the suppor

Computer numerically controlled (CNC) punching is a sheet metal manufacturing process that is carried out by CNC punch presses. These machines can be either a single head and tool rail (Trumpf) design or multi-tool turret design. The CNC punching machine is basically programmed to move a sheet of me

Clean the hydraulic oil The hydraulic system has the high requirement for the cleanliness of hydraulic oil. The clean of the oil tank is very important. When replacing the hydraulic oil, you must discharge the cover of the oil tank. Usethe towel to clean the bottom of the tank(do not use cotton ya

This is one complete operation manual for the swing beam shearing machine, which is also very popular hydraulic shearing machine. You can check out the Hydraulic guillotine shears operation manual in another post.

It is very common for press brake operators to have their own personal “rule of thumb” when choosing the V opening for a certain job application. Although these rules may have developed over time from their personal experience, they do not take into account how commercial sheet metals actually beh

According to relative position of the upper and lower molds in the bending process, the press brakes processing can be divided into two ways:Air bending and press to the bottom bending.

Design of the Hydraulic System Figure 7 shows the design of the hydraulic circuit system of the metal folding machine.

•Roll-bending –bending plates with a set of rolls•Beading –bending the periphery of sheet metal into a cavity of a die to improve appearance and eliminate exposed edges•Flanging –bending edges of sheet metal to 90 degrees•Dimpling –punching a hole, followed immediately by flanging the edges•Hemming
