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 to Fig. 3, the invention provides a kind of positive top-cross knife structure of diel, comprise a counterdie 1, also comprise the material pressing core 2 of a compacting processing workpiece, wherein, also comprise the side blow cutter block 3 of cut workpiece from the side and the positive stamping knife block 4 of downward cut workpiece.
Further, arrow C direction is side blow cutter block 3 cut direction, arrow D direction is the cut direction of positive stamping knife block 4, one end of described side blow cutter block 3 cut surface is provided with a protuberance 31, described positive stamping knife block 4 is provided with a recess 41 near one end of side blow cutter block 3, it is mutually adaptive that protuberance 31 and recess 41 are set to size shape, described protuberance 31 and recess 41 cooperatively interact make described side blow cutter block 3 and described positive stamping knife block 4 simultaneously cut workpiece time do not touch mutually.
Certainly; protection domain in the present invention is not limited in and arranges protuberance on side blow cutter block 3; positive stamping knife block 4 arranges the mode of recess; as another embodiment of the invention; one end of side blow cutter block 3 cut surface can be provided with a recess; positive stamping knife block 4 is provided with a protuberance (not indicating in figure) near one end of side blow cutter block, and this setup can reach equally avoids positive stamping knife block and side blow cutter block to produce the effect of interfering.
Preferably, described positive stamping knife block 4 and side blow cutter block 3 manufactured materials are the casting spatial chilled steel.For the cutter of shaving die, the workpiece cut mostly is sheet metal component, require that the edge of a knife has enough hardness, cutter block matrix then requires to possess enough toughness, and air cooling steel is the shorterizing material of non-convention, quenching wide ranges, quenching degree is good, and deformation rate is little, and air cooling steel can obtain edge of a knife local high rigidity after Quenching Treatment, and cutter matrix does not lose original toughness, therefore the casting spatial chilled steel is very suitable is applied to positive stamping knife block 4 of the present invention and side blow cutter block 3.
As another embodiment of the invention, described positive stamping knife block 4 and side blow cutter block 3 manufactured materials also can be carbon tool steel, and this material price is cheap, low cost of manufacture.
As another embodiment of the invention, described positive stamping knife block 4 and side blow cutter block 3 manufactured materials are alloy tool steel, alloy tool steel can apply the improvement that multiple Technology for Heating Processing carries out performance, if Cr12 mould steel is after micronization processes, not only hardness, intensity increase, and toughness, impact resistance also can significantly promote, seem particularly important as cutter impact resistance, the alloy tool steel that can carry out multiple Technology for Heating Processing processing be can yet be regarded as a kind of desirable shaving die cutter material.
Further, described side blow cutter block 3 and positive stamping knife block 4 are driven by driving mechanism respectively.
Below for work flow illustrates:
Side blow cutter block 3 is driven by wedge, and wedge has certain angle so produce lateral separation just in time there is certain distance with positive stamping knife block 4, start to add man-hour material pressing core 2 first push down part then upper cutter block down process in advance, because side blow cutter block 3 exists a time difference now not to the distance of processing work by wedge driving with positive stamping knife block, positive stamping knife block 4 continues desired space when positive stamping knife block 4 side toward pressing down has a recess just to avoid side blow cutter block complete processing parts, now complete the positive side of part to processing.Because the position of terminal is left in wedge during the space die sinking of positive stamping knife block 4 with side blow cutter block 3 life period difference and action while of positive stamping knife block 4 during return, side blow cutter block 3 is followed and is left so laterally the certain distance of generation just can allow again positive stamping knife block 4 not produce interference by side blow cutter block 3 smoothly according to wedge angle, and material pressing core 2 leaves part again and completes processing.Consider that positive stamping knife block 4 has a recess can affect the strength problem of cutter block, this scheme is comparatively applicable to the little part of the thinner shearing strength of some thickness ratios of processing.
The present invention is by providing a kind of positive top-cross knife structure of diel, side blow cutter block and positive stamping knife block arrange recess and protuberance, avoid the problem producing when side blow cutter block and positive stamping knife block run simultaneously and interfere, make shaving die can carry out the trimming operation of forward and side direction simultaneously, substantially increase production efficiency, reduce production consuming time.
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.
