Detailed description of the invention
For making object of the present invention, technical scheme and advantage clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.
Consult Fig. 1, Fig. 1 is that the drift of the diel of prior art arranges structural representation, and drift 6 carries out punching to workpiece from left to right, drives the drive block of drift 6 and workpiece to be processed easily to produce interference; In addition, the drift of this class formation directly carries out punching to workpiece, adds the reaction force that the power that puts on workpiece man-hour causes and puts on drift 6, easily cause the play of drift and advance instability, reducing machining accuracy.
Consult Fig. 2, the invention provides a kind of reverse punch structure for inclined plane shape, wherein, comprise a base 1, also comprise a slide block 2, one end of described slide block 2 bottom is provided with the first drive block 3, described base 1 top is provided with the second drive block 4, described first drive block 3 and the second drive block 4 are slidably connected, and also comprise the drift 6 that a pair workpiece to be processed carries out punching, described drift 6 is arranged at one end of described slide block 2 bottom.Compared to Figure 1, drift of the present invention is set to turn left lower stamped workpieces from upper right, drives the slide block 2 of drift 6 can not produce interference with workpiece.
Further, one end of described slide block 2 is provided with elastic portion 5, and described elastic portion 5 is resetted to slide block 2 by himself elastic force after drift 6 pairs of workpiece punchings.
Preferably, described elastic portion 5 is spring, can select nitrogen spring, and nitrogen spring take high pressure nitrogen as working media, and volume is little to be easily installed in slide block 2, elastic force is large, stable working, and precision is high, and spring curve is mild, is highly suitable for diel field.
Further, consult Fig. 3, described first drive block 3 is matrix guide plate, described second drive block 4 is convex guide plate, the first drive block 3 being set to matrix and the second drive block 4 being set to convex are slidably connected, during punching, slide block 2 oliquely downward slides along this secondary glide direction that is slidably connected, and drives drift 6 oliquely downward to carry out puncture motion, and the first drive block 3 and the second drive block 4 play a part guiding drift 6 direction of motion; Moreover, when drift carries out punching to workpiece, drift can be subject to the active force of workpiece to it, this active force can be passed to whole pressing equipment, easily cause the play of drift and advance instability, the sliding fulcrum when pair that is slidably connected of guide plate composition is oliquely downward slided as slide block 2, to slide block 2 support supporting roles, make drift 6 punch process more steady, reduce play.
Preferably, the first drive block 3 is recessed V-type guide plate, and the second drive block 4 is convex V-type guide plate.As another embodiment of the invention, described first drive block 3 can be set to convex V-type guide plate, and described second drive block 4 is set to recessed V-type guide plate.V-type guide plate uniform force, between the slide unit of sliding pair, relative sliding is smooth.Certainly, in the present invention, the first drive block and the second drive block are not limited in the form being set to V-type guide plate, consult Fig. 5, and as another embodiment of the present invention, the first drive block 3 can be set to concave-curve guide plate, and the second drive block 4 is convex guide plate.Consult Fig. 6, the first drive block 3 can be set to convex arc type guide plate, and the second drive block 4 is arcs of recesses guide plate.The secondary friction that is slidably connected of arc-shaped guide plate composition is little, can improve sliding speed to a certain extent, accelerate punching efficiency.Consult Fig. 7, as another embodiment of the present invention, the first drive block 3 can arrange recessed square guide plate, and the second drive block 4 is convex square guide plate.Consult Fig. 8, the first drive block 3 can arrange convex square guide plate, and the second drive block 4 is recessed square guide plate.
Further, described slide block 2 top bolt connects a die holder (not indicating in figure), and driving mechanism promotes die holder downwards to be with movable slider 2 to move downward.
The angle that wedge drive block of the present invention is arranged is parallel with wanting the punch direction of punching, be arranged on the other end on punching inclined-plane, add man-hour material pressing core first part to be pushed down, slide block 2 continues to walk downward and touches drive block and produce side force and promote slide block and produce oblique movement, compression return spring, simultaneously also because the angle of drive block drives thus the hole processed on inclined-plane.Now mould runs to bottom pressure machine return and is greater than slide block 2 own wt and frictional force without the power that downforce return spring produces thus makes it back do sliding action.Interference when this structure can avoid the horizontal feeding of the clamping of manipulator, part in multistation automatic punching die, cost is low, precision is high, easy installation, easy-maintaining.
A kind of punching technology, comprises the following steps:
A. workpiece is positioned on base 1, by the alignment pin being installed on base 1, workpiece is accurately located;
B. driving mechanism is started, driving mechanism promotes the die holder be connected with slide block, second drive block 4 relative sliding on the first drive block 3 on slide block 2 and base 1 top, slide block 2 oliquely downward slides along the secondary glide direction that is slidably connected of the first drive block 3 and the second drive block 4 composition, and slide block 2 drives drift 6 pairs of workpiece to carry out punching;
C., after punching, slide block 2 resets under the elastic force effect of elastic portion 5.
The present invention is by providing a kind of reverse punch structure for inclined plane shape, shape and structure feature for product workpiece arranges the problem that drift and slide block are interfered to solve product and mould, and it is more steady during by arranging two drive blocks that are slidably connected and making drift punching, avoid producing play, improve machining accuracy and crudy.
Should be understood that, application of the present invention is not limited to above-mentioned citing, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to claims of the present invention.
