What are the classification of hydraulic plate shears?

sheet metal shearing machine according to the shape of the scissors is divided into straight knife shear cutting machine and disc knife shearing machine.Straight knife cnc shearing machinemachine is divided into gantry plate shearing machine and throat plate shearing machine according to structure.Disc knife plate shearing machine according to the structure is divided into disc shearing machine, rolling shearing machine, multi disc plate shearing machine and rotary trimming plate shearing machine.

According to the movement trajectory of the tool rest, the plate shearing machine is divided into the following kinds:

(1) the tool rest moves along the vertical line, because there is no forward inclination, so the cross section of the upper blade must be processed into a diamond, so there are only two edges (four blade rectangular blades are also available, but the cutting quality is poor), and the cutting fracture of the tool rest is not a right Angle to the plate surface.

(2) the tool carrier moves along the forward inclination line (the included Angle with the vertical line is 1°30'~2°), and the cross section of the upper blade can be processed into a rectangle, with four blade edges, and the cutting fracture is basically at a right Angle to the plate surface.

(3) The tool rest swings along the arc line, and the section of the cutting blade should be processed into a diamond, so there are only two blade edges. Because the upper blade tilts slightly forward in the cutting process, the cutting quality is similar to the movement of the tool rest along the tilting line.

(4) the tool rest swings along the circular arc line, and the rake Angle can reach 300, so the welding groove can be cut out

According to the transmission mode classification plate shearing machine according to the transmission mode is divided into: mechanical transmission plate shearing machine and hydraulic transmission shear trigger

Hydraulic shears are driven by two hydraulic cylinders, so the synchronization of the two hydraulic cylinders needs to take some technical measures.Using single cylinder connecting rod structure, which is to transfer the work force of the hydraulic cylinder to the front and rear triangle of main stress components, as a result of the hydraulic cylinder force between the axis of the action line and it has a eccentric torque e, so it is under eccentric load is mainly tensile load, therefore its main mechanical structure design of cross section for the i-section, synchronization issues resolved naturally.
