Abstract
The utility model relates to the machine class, in particular to an upper tool carrier driving gear of plate shears, mainly consisting of a torsion axis, an oil cylinder and a driving arm; wherein, the torsion axis is fixedly supported on the wallboard of the machine, and the driving arm is symmetrically fixed to both sides of the torsion axis; one end of the driving arm is movably connected with one end of the oil cylinder, and the other end of the driving arm is movably connected with the upper slide rest which is movably connected with the other end of the oil cylinder. The utility model has the advantages of simple structure, strong shearing, high driving efficiency of the oil cylinder hydraulic pressure and rapid shearing speed.
Description
Technical field
The utility model relates to the lathe class, is a kind of plate shearing machine upper tool post transmission mechanism concretely.
Background technology
Upper tool post of the prior art, be generally the steel plate weldment, has favorable rigidity, as shown in Figure 1, it is that fulcrum is on a left side with eccentric bushing (1), make reciprocally swinging under the driving of right oil cylinder (2) and accumulator kicker cylinder (3) and finish shearing, the left side of this structure, right oil cylinder is separately fixed on the frame wallboard, the shortcoming of this structure is that the reaction force of shearing force all bears on frame, vibration is big, need the backhaul cylinder finish drawback movement, need accomplish fluently lower margin and lathe is securely fixed on the ground processes, shear rate is slow, impulsive force is big, directly influence processing quality, again since upper tool post by cylinder support, when cylinder take place to leak, upper tool post can fall automatically, poor safety performance.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, a kind of plate shearing machine upper tool post transmission mechanism is provided, in this mechanism upper tool post is made that by a pair of oil cylinder and transmission arm, torsion shaft whole upper tool post can be under the effect of double reaction plus, move downward, realize shearing by the cutter that is installed on the knife rest.
The utility model purpose realizes being finished by following technical scheme:
A kind of plate shearing machine upper tool post transmission mechanism, this mechanism mainly is made of torsion shaft, oil cylinder, transmission arm, wherein torsion shaft is fixedly supported upon on the left and right wallboard of frame, the transmission arm symmetry is fixed on the two ends of torsion shaft, one end of transmission arm and an end of oil cylinder flexibly connect, the other end and upper tool post flexibly connect, and the other end of oil cylinder and upper tool post flexibly connect.
Described flexible connection can be that hinge connects, or the bearing pin connection, perhaps adopts oscillating bearing to connect.Torsion shaft is fixedly supported upon on the frame wallboard, the two ends that refer to torsion shaft are fixed with the supporting spindle nose respectively, the supporting spindle nose is bearing on the wallboard by bearing, the transmission arm symmetry is fixed on the two ends of torsion shaft, and the fixing fixed form of the fixing and transmission arm of aforesaid supporting spindle nose all can adopt bolted mode or adopt welding manner or adopt key to connect.
The utility model has the advantages that simple in structure, shearing force is big, the efficient height of oil cylinder hydraulic transmission, shear rate are fast, that complete machine operates steadily, vibrates is little, need not to beat lower margin.
Summary of drawings
Accompanying drawing 1 is the utility model prior art structural representation;
Accompanying drawing 2 is the utility model structural representation;
Accompanying drawing 3 is the utility model side structure schematic diagram;
Concrete technical scheme
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technical staff's of the same trade understanding:
As Figure 1-3, label 1-13 represents respectively: eccentric bushing (1), oil cylinder (2), accumulator kicker cylinder (3), torsion shaft (4), wallboard (5), oil cylinder (6), cutter (7), upper tool post (8), hinge (9), hinge (10), supporting spindle nose (11), transmission arm (12), hinge (13).
The product of present embodiment mainly is made of torsion shaft (4), oil cylinder (6), transmission arm (12), wherein the two ends of torsion shaft (4) are fixed with supporting spindle nose (11) respectively, supporting spindle nose (11) is bearing on the wallboard (5) by bearing, two transmission arms (12) symmetry is fixed on the two ends of torsion shaft (4), above-mentioned fixed form all can adopt bolt to connect or adopt welding, also can adopt key to connect, adopt welding effect relatively good usually.Oil cylinder (6) one ends and upper tool post (8) flexibly connect by hinge (9), and the other end flexibly connects by the A end of hinge (10) with transmission arm (12), and the B end and the upper tool post (8) of transmission arm (12) flexibly connect by hinge (13).
When lathe was not worked, upper tool post (8) was bearing on the wallboard (5) by supporting spindle nose (11) by torsion shaft (4) and can fall voluntarily.When the piston rod of oil cylinder (6) moves downward, make upper tool post (8) be subjected to downward active force by hinge (9), and the A end of the opposite force promotion transmission arm (12) of oil cylinder (6) upper end is up, the B end of transmission arm (12) then promotes upper tool post (8) and moves downward, promptly make upper tool post (8) be subjected to a downward active force again, this shows, the structure of present embodiment can be so that the overwhelming majority of the pressure that oil cylinder (6) produces be used for shearing, it is very little that lathe is subjected to the influence of reverse impact power, thereby lathe work the time can not vibrate, and security performance is very high.
Though below design and embodiment according to the utility model purpose are described in detail with reference to accompanying drawing, but those of ordinary skills can recognize, under the precondition that does not break away from the claim limited range, still can make various improvement and conversion to the utility model, change of the change of for example change of transmission arm shape, upper tool post version, oil cylinder and upper tool post connected mode or the like.
Claims (5)
