Below 1 U-typed slot, does not need complicated upper beam and be used to installation oil cylinder.
As shown in Figure 1 and Figure 2, on the fixed lathe bed 1 of lower knife assembly 2, guarantee cut level and with the upper slitter in upper knife assembly 5
In parallel.Binder component 3 is mounted on the upper cutter head of knife assembly 5, is the general indispensable configuration of plate shearing machine, movement and principle are homogeneous
Together, it is not repeating.
As shown in figure 4, guidance set is by being mounted on upper slitter on the outside of the guide-rail plate 14,15,16,17 and lathe bed 1 in U-typed slot
Limited roller group 4 on seat 5 forms.Guide-rail plate 14,16 is preferably copper sheet, is fixed by screws on upper cutter head 5；Guide-rail plate
15,17 be wear-resisting steel plate, and guide-rail plate 15 is fixed by screws on the U-typed slot of lathe bed 1, and guide-rail plate 17 is solid by Push-pull bolt
It is scheduled on the U-typed slot of lathe bed 1, for adjusting the glade plane space of upper cutter head 5.
As shown in figure 4, limited roller group 4 is made of limited roller 13, roller shaft 11, guide-rail plate 10 etc..Limited roller 13
For wear-resistant steel wheel, it is mounted on upper cutter head 5 by roller shaft 11.Sliding sleeve 12 is housed between limited roller 13 and roller shaft 11, with
Conducive to the rotation of idler wheel 13, and utilize nut to 13 axial restraint of idler wheel by spacer.Guide-rail plate 10 is preferably wear-resisting steel plate,
It is fixed by screws on the outer end face of U-typed slot of lathe bed 1, cooperates with limited roller 13 and slide, and be reserved with preferably most
Big 0.5 millimeter of gap.
As described above, the limit of 14,15,16,17 pairs of upper cutter heads 5 of guide-rail plate ensure that upper slitter is parallel with what is cut；Limit
Roller group 4 limits the lateral displacement of upper cutter head, and has reserved gap and adjusted to angle.The external installation of two oil cylinders 8 also obtains
To realize.The present invention is achieved that lathe bed component without complicated upper beam through the above structure, and structure is simply light-weight, and oil cylinder is external
It is easily installed and equipment center of gravity is low.The big slab shearing of width is suitable for using the plate shearing machine of such structure, is also suitable for as shifting
The packaged type cut cells that motion tracking is cut.
The hydraulic system is placed outside outside plate shearing machine, by the General hydraulics such as fuel tank, motor, pump, servo valve group and pipeline member
The movement respectively and the synchronization action that accurately control two oil cylinders may be implemented in part composition, servo valve group.Two oil cylinders 8 act respectively
To adjust the angle of shear, synchronization action is for shearing plate.
The control system is placed outside outside plate shearing machine, logical by programmable PLC controller, manipulation display, manipulation cabinet etc.
Electrical appliance element composition.There are power supply line and signal wire phase between the control system and the motor and servo valve group of hydraulic system
Even.PLC controller is composed of program in advance, inputs parameter on manipulation display, can pass through the servo valve group control of hydraulic system
It makes two oil cylinders and acts respective value respectively, be also achieved that the digital display of shearing inclination, the automatic adjustment of numerical control.
Fig. 5 is that the angle of shear of the present invention adjusts schematic illustration, as shown, F is shearing force in figure, Fv hangs down for shearing force
Straight component, Fh be shearing force horizontal component, L1 be lathe bed on guide rail spacing, gap of the L2 between limited roller and guide rail,
L3 is the changing value of cutting stroke after angle of shear adjustment, and R is limit roller radius, and a is angle of shear adjusted value.
As shown in figure 5, because upper slitter tilts, effect of the upper knife assembly 5 in the horizontal component Fh of shearing force F in shear history
Under, upper slitter upwarps Sutureless between the limited roller of one end and bed ways plate and contacts, other end limited roller and bed ways
There is reserved gap L 2 between plate.The oil cylinder 8 for being placed outside 5 both ends of knife assembly is utilized in advance by the servo valve group of hydraulic system
The gap L 2 stayed adjusts the difference in height that cylinder rod is stretched out, and according to trigonometric function relationship, available upper slitter adjustable shear angle [alpha] is most
Big value are as follows:
If fruit is to reduce angle, cutting stroke reduces L4, numerical formula are as follows:
L4=(L1+L2+2R) * sin α.
It is calculated, L1=2555mm, L2=0.5mm, R=65mm, is substituted into the data of one embodiment of the invention
Formula calculates: maximum angle adjustable α=1.1 °；Maximum adjustable shear stroke L4=51.6mm.
For inclined edge plate shearing machine, the angle of shear of plate thickness 10mm or more is preferably 2~2.2 °, and plate thickness 5mm is below to be cut
Corner cut is preferably 1.2~1.6 °.This adjusting range is practical to meet.
For tracking transverse shearing production line, because the plate movement that remains a constant speed does not stop in shear history, shear time is shorter
Better, for shear time less than 2 seconds, it is also very effective for improving thin plate shear velocity that cutting stroke shortens 51.6mm.
Paper " the inclined edge that first invention people delivers in " Forging equipment and manufacturing technology " the 4th phase in 2009 according to the present invention
The research of plate shearing machine shearing force " in the formula mentioned: shearing force p=0.3 σbh2/ tan α can be calculated same for same plate thickness
Template material increases the variation of the required shearing force after the angle of shear.Such as plate thickness h=10mm, σb=500N/mm2Q235A plate,
Shearing force p=71.6 tons is calculated when angle of shear α=1.2 °；Shearing force p=39 tons is calculated when angle of shear α=2.2 °.It can be seen that adjustment
1 ° of the angle of shear, it can greatly expand the range of work of plate shearing machine in the case where not increasing system pressure.
The above is only the preferred embodiment of this patent, it is noted that for the ordinary skill people of the art
For member, under the premise of not departing from the art of this patent principle, several improvement and replacement can also be made, these are improved and replacement
It should be regarded as the protection scope of this patent.
