Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is described in detail.
As shown in Figure 1, 2, a kind of punch mechanism fast, it comprises driving cylinder 1, pedestal 2, bar linkage structure, motion drift 5, the fixing drift 6 coordinating with motion drift 5, the cylinder body 11 of driving cylinder 1 is fixed on pedestal 2, the piston rod 12 of driving cylinder 1 is hinged with bar linkage structure, motion drift 5 is fixedly connected with bar linkage structure, and fixing drift 6 is fixedly connected with pedestal 2.
Bar linkage structure can adopt a bar or many connecting rods, preferred, and bar linkage structure comprises connecting rod 3 and carry out bar 4, the two ends of connecting rod 3 respectively with piston rod 12, to carry out bar 4 hinged, carries out bar 4 hinged with pedestal 2, motion drift 5 is fixedly connected with execution bar 4.Piston rod 12 rectilinear motion drivening rods 3, carry out bar 4, motion drift 5 and move, realize coordinating of motion drift 5 and fixing drift 6.Adopt bar linkage structure rationally to arrange the blanking pressure of movable ram.
Driving cylinder 1 can be hydraulic cylinder, cylinder, and driving cylinder 1 is started working, and piston rod 12 motion drivening rods 3 and execution bar 4 move, and cylinder power output are converted to the blanking pressure at stamping-out head place.Between motion drift 5 and fixing drift 6, have fit clearance, workpiece is between motion drift 5 and fixing drift 6, and motion drift 5 moves and then realizes workpiece punching to fixing drift 6.Conventional diameter cylinder power output is less than theoretical blanking pressure, so need to pass through the amplification of connecting rod 3 structure realizable forces.
Pedestal 2 can be a part, also can there be multiple assembling parts to form, preferably, pedestal 2 comprises the first bearing 21 and the second bearing 22 that connect as one, the cylinder body 11 of driving cylinder 1 is fixedly connected with the first bearing 21, carry out bar 4 and be fixedly connected with the second bearing 22, fixing drift 6 is fixedly connected with the first bearing 21.The first bearing 21 can be connected to realize by welding, riveted joint, bolt with the second bearing 22 to be fixed, and adopts said structure to be convenient to processing, assembling.
Preferably, punch mechanism also comprises the waste material box 7 for receiving stampings fast, and waste material box 7 is fixedly connected with the first bearing 21.
Arranging of connecting rod 3 angles has a direct impact the size of blanking pressure, preferred, and punch mechanism is in the time of original state fast, and connecting rod 3 is 60～80 degree with the angle of carrying out bar 4.Fig. 3 be quick punch mechanism in the time of original state, the stressed schematic diagram of each structure, in Fig. 3, c is the pin joint of piston rod and connecting rod, b is connecting rod and carry out the pin joint of bar, a is the pin joint of carrying out bar and pedestal.As shown in Figure 3, the calculating of actual blanking pressure: cylinder power output is F, component the F '=F/cos α on connecting rod 3, component the F1=F ' × cos β on drive rod, according to equalising torque F1 × L1=F2 × L2.Therefore draw: blanking pressure F2=F × (cos β × L1)/(cos α × L2).Conventionally choose L1=L2, therefore, as long as β is less than α, just can realize the amplification of power output, connecting rod 3 and the angle of execution bar 4 are 60～80 while spending, can ensure that F2 is greater than F, have realized the amplification of active force.Can consider the level that self frock is manufactured, suitable change.But for the selection of angle, must consider the realizability of tooling device because when angle beta more hour, the multiple that blanking pressure amplifies also rises rapidly, also stricter to the required precision of tooling device, need to consider the impact that foozle is brought carefully.
Carry out bar 4 for having connecting rod 3 structures of two revolute pairs, its version can have various deformation.Preferably, carry out bar 4 L-shaped, connecting rod 3 is positioned at the turning point of carrying out bar 4 with the pin joint of carrying out bar 4, and pedestal 2 lays respectively at the two ends of carrying out bar 4 with pin joint, the motion drift 5 of carrying out bar 4 with the stiff end of carrying out bar 4.The execution bar 4 that adopts said structure, is fixedly hinged and is a little positioned at turning point, is conducive to effective transmission of power.
A kind of welding production line, the quick punch mechanism that it comprises.When this quick punch mechanism is used on welding production line, can realize full-automatic online punching.In the time using this mechanism to carry out punching,, can synchronously carry out without impact other operations such as the spot welding on this station.Whole operation process can complete about 10 seconds, realization that can the stability and high efficiency online punching that is welded.This mechanism has not only reduced product development cost, has shortened the construction cycle, and its precision also can obtain stable lifting, and technologist also can be more flexible in the time carrying out technological design.
Although the utility model is described in conjunction with above embodiment, but the utility model is not limited to above-described embodiment, and be only subject to the restriction of claims, those of ordinary skill in the art can easily modify to it and change, but do not leave essence design of the present utility model and scope.
