Description

A kind of diel die shank

Technical field

The utility model relates to mould applications, particularly relates to a kind of diel die shank.

Background technology

Sheet Metal Forming Technology is a kind of cutting highly efficient in productivity, few or the advanced processing method without cutting, all has a lot of advantages in economy and technical elements.It is easy and simple to handle, is convenient to realize mechanization and automation, is suitable for the production of part more in enormous quantities, and its goods generally do not need to make further machining, and dimensional accuracy and interchangeability are also all relatively good.So it occupies very consequence in the industry such as aviation, automobile, tractor, electrical equipment and electrical, precision instrumentation.In the middle of punching production, diel is the concrete executing means of Sheet Metal Forming Technology; In fact, the design level of punching die structure and the accuracy of manufacture are the keys ensureing stamped part quality.Die shank is mounted in the part of the uppermost handle of cope match-plate pattern, type has a variety of, because diel will install on forcing press, the slide block of forcing press has a hole, this hole is exactly the place that die shank inserts, slide block has retaining mechanism, and when Design of Dies, die shank will will conform to the shank hole of forcing press.The effect of die shank makes cope match-plate pattern on forcing press, have a position more accurately, also needs guide pillar guide pin bushing during required precision height, and the slide block of forcing press is when rising, and also needs the power that die shank moves upward to transmit cope match-plate pattern.When but die shank of the prior art is arranged on cope match-plate pattern, easy appearance loosens, and because die shank is Bonding pressure machine and cope match-plate pattern, this reduces the hauling ability of die shank, although and at present have the method solving problems in the middle of technology, effect is not remarkable.

Summary of the invention

In order to solve the deficiencies in the prior art, the utility model provides a kind of diel die shank, and this die shank structure is simple, easy to use, not easily occurs loosening phenomenon.

It is that a kind of diel die shank, comprises cope match-plate pattern, die shank, block, fastener, major axis screw that the utility model solves the technical scheme that its technical problem adopts, and cushion, fastening nut that major axis screw matches; The upper end of cope match-plate pattern is fixed with two blocks, and block divides the die shank installing hole two ends being located at cope match-plate pattern; Die shank is provided with the cylindrical bore matched with major axis screw with the central part of block contact position; Block is provided with the through hole with cylindrical bore opposite position on die shank, and through-hole wall is provided with the screw thread matched with major axis screw; Block is provided with fastener, and for fixing major axis screw further, when preventing mold work, the activity of major axis screw causes die shank to loosen.

During use, first die shank is placed on the die shank installing hole of cope match-plate pattern, by the through hole relativity in cylindrical bore and block, forms a passage that major axis screw can be allowed to pass through; By major axis screw from one end of block, enter block through hole successively, the cylindrical bore on die shank and another block through hole, cushion on the end cover of screw, and screw fastening nut; After major axis screw installs, the fastener on block is screwed, to strengthen the fastening effect of major axis screw further.

The beneficial effects of the utility model are, a kind of diel die shank, and major axis screw runs through two blocks and die shank, and jointly coordinates with cushion and fastening nut, and cope match-plate pattern is firmly not easily loosened under the drive of forcing press; The setting of fastener on block, make major axis screw also not easily movable under the drive of forcing press, further enhance the fastening effect of die shank, improve the service behaviour of forcing press and diel, its structure is simple, easy to use.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further described.

Fig. 1 is the schematic diagram of diel die shank.

1. cope match-plate patterns, 2. die shank in figure, 3. die shank installing hole, 4. block, 5. major axis screw, 6. cushion, 7. fastening nut, 8. fastener.

Detailed description of the invention

With reference to accompanying drawing, a kind of diel die shank, comprises cope match-plate pattern 1, die shank 2, block 4, fastener 8, major axis screw 5, and cushion 6, fastening nut 7 that major axis screw matches; The upper end of cope match-plate pattern 1 is fixed with two blocks 4, and block 4 points is located at die shank installing hole 3 two ends of cope match-plate pattern 1; Die shank 2 is provided with the central part of block 4 contact position the cylindrical bore matched with major axis screw 5; Block 4 is provided with the through hole with cylindrical bore opposite position on die shank 2, and through-hole wall is provided with the screw thread matched with major axis screw 5; Block 4 is provided with fastener 8, and for fixing major axis screw 5 further, when preventing mold work, major axis screw 5 activity causes die shank to loosen.
