Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, clearly, develop simultaneously embodiment to this utility model further description referring to accompanying drawing.
Consult Fig. 1 to Fig. 3, this utility model provides the positive top-cross knife structure of a kind of diel, including a counterdie 1, also includes the material pressing core 2 of a compacting processing workpiece, wherein, the side blow cutter block 3 cutting workpiece from the side and the positive stamping knife block 4 cutting downwards workpiece are also included.
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 facet 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, protuberance 31 and recess 41 are set to size shape and are mutually adapted, and described protuberance 31 and recess 41 cooperate and make described side blow cutter block 3 and described positive stamping knife block 4 not touch mutually when cutting workpiece simultaneously.
Certainly; protection domain in this utility model is not limited in arranging protuberance on side blow cutter block 3; positive stamping knife block 4 arranges the mode of recess; as another embodiment of the present utility model; one end of side blow cutter block 3 facet 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 equally possible the reaching of this setup avoids positive stamping knife block and side blow cutter block to produce the effect interfered.
Preferably, described positive stamping knife block 4 and side blow cutter block 3 manufacture material is the casting spatial chilled steel.Cutter for shaving die, the workpiece cut mostly is sheet metal component, requiring that the edge of a knife has enough hardness, cutter block matrix then requires 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 particularly suitable for and is applied to positive stamping knife block 4 of the present utility model and side blow cutter block 3.
As another embodiment of the present utility model, it can also be carbon tool steel that described positive stamping knife block 4 and side blow cutter block 3 manufacture material, and this material price is cheap, low cost of manufacture.
As another embodiment of the present utility model, it is alloy tool steel that described positive stamping knife block 4 and side blow cutter block 3 manufacture material, alloy tool steel can be applied multiple Technology for Heating Processing and carry out the improvement of performance, if Cr12 mould steel is after micronization processes, not only hardness, intensity increase, and toughness, impact resistance also can be substantially improved, it is particularly important as cutter impact resistance, it is possible to carry out the alloy tool steel of multiple Technology for Heating Processing processing and can yet be regarded as a kind of desirably shaving die cutter material.
Further, described side blow cutter block 3 and positive stamping knife block 4 are driven by driving mechanism respectively.
Hereinafter illustrate for work flow:
Side blow cutter block 3 is driven by wedge, and wedge has certain angle so producing lateral separation just there is certain distance with positive stamping knife block 4, start to add man-hour material pressing core 2 first to push down part then upper cutter block and down process in advance, owing to side blow cutter block 3 is driven with positive stamping knife block one time difference of existence now not to the distance of processing work by wedge, positive stamping knife block 4 continues down pressure and positive stamping knife block 4 side to be had a recess just to avoid side blow cutter block to process desired space during part completely, now complete the positive side of part to processing.During return due to when there is the space die sinking of time difference in positive stamping knife block 4 and side blow cutter block 3 wedge and the action simultaneously of positive stamping knife block 4 leave the position of terminal, side blow cutter block 3 is with leaving according to wedge angle so the certain distance of horizontal generation just can allow again positive stamping knife block 4 pass through side blow cutter block 3 does not produce interference, and material pressing core 2 completes processing further out part.Considering the strength problem that positive stamping knife block 4 has a recess can affect cutter block, this scheme is comparatively suitable for the part that the processing relatively thin shearing strength of some thickness ratios is little.
This utility model is by providing the positive top-cross knife structure of a kind of diel, side blow cutter block and positive stamping knife block arrange recess and protuberance, the problem avoiding side blow cutter block and produce to interfere when positive stamping knife block runs simultaneously, make shaving die can carry out forward and lateral trimming operation simultaneously, substantially increase production efficiency, reduce production consuming time.
Should be understood that; application of the present utility model is not limited to above-mentioned citing; for those of ordinary skills, it is possible to improved according to the above description or convert, all these improve and convert the protection domain that all should belong to this utility model claims.
