We are always confused by a question that why hydraulic shearing machines are divided into swing beam shear and guillotine shear.why we say [url=http://www.visionbaler.com/hydraulic-guillotine-shear/]hydraulic guillotine shear[/url] is upgraded version of hydraulic swing beam shear.compared with the hydraulic swing beam shear,what are the advantages of hydraulic guillotine shear ?

                        

Firstly we lists the key differences between QC12 series swing beam shear and QC11 series hydraulic guillotine shear:

                    

Blade carrier cutting movement

Hydraulic Swing Beam Shears: – Unipivot support,lever principle;Do arc-shaped curvilinear motion around the rear fulcrum.

Hydraulic Guillotine Shears: – Three-point support rolling guide(Lower eccentric shaft, front support shaft,upper eccentric shaft; Do linear vertical motion.

                    

Blade style:

Hydraulic Swing Beam Shears: – Top blade in prismatic shape,can only use two bevel angle cutting edge;Lower blade in rectangular shape,four cutting edge can be used.

Hydraulic Guillotine Shears: – Both upper and lower blade are in rectangular shape;–All four cutting edge can be used.

                    

Cutting angle adjustment:

Hydraulic Swing Beam Shears: – Fixed cutting angle and blade carrier angle;Can only cut in specific angle whatever the thickness of the plate.

                    

Hydraulic Guillotine Shears: – Adjustable cutting angle, different cutting angles are applied for cutting plate with different thickness.Adopt smaller cutting angle can effectively reduce the distortion of sheet metal, and increase cutting speed;Can also increase the shear angle to increase the shear force.

                    

Lubrication point

Hydraulic Swing Beam Shears: – Bevel gears are heavily worn and require frequent lubrication to increase service life.

Hydraulic Guillotine Shears: – Most use self-lubricating spherical plain bearings, basically don’t need to manually lubricate.

                    

Backstop structure (optional)

Hydraulic Swing Beam Shears: – 500W AC motor + universal connection twisted shaft;Easy to cause gaps, no spring buffer, no retract function.

Hydraulic Guillotine Shears: – Inverter + speed motor + encoder + electronic digital display;Stepless speed regulation, low noise, spring retraction and buffer function.

The hydraulic shears are more accurate than the hydraulic swing beam shears



Shear Accuracy

Take 16*3200 hydraulic swing beam plate shears and hydraulic brake plate shears,Both of the blade clearance of the swing beam shear and guillotine shear is 0.04 mm.However, the clearance of the bearing connection between the swing arm and the pendulum body of the swing beam shearing machine cannot be completely eliminated.The accuracy errors between gaps and blade edge clearance are generally above 0.1 mm.Therefore, the accuracy of the swing beam shearing machine is theoretically twice worse than the guillotine shearing machine.The rear guide rail of the guillotine shearing machine is pressed by the bearing withthe compression spring pad on the back, so that there is no gaps between the front and rear guide rails.

                    

The accuracy of the gap between the clearance and the blade edge gap is kept below 0.04 mm, so that the shear material can be made smoother and no burrs.
