Abstract
The invention discloses a connecting piece shaping punching die. The connecting piece shaping punching die comprises a die handle, an upper die plate installed at the bottom of the die handle, a fixing plate arranged below the upper die plate, guide columns with one ends arranged at the bottom of the fixing plate, a stripper plate arranged at the other ends of the guide columns, a rubber arranged between the fixing plate and the stripper plate, a female die arranged below the stripper plate, a lower die plate arranged below the female die, and punching male dies which are arranged on the inner sides of the guide columns and penetrate the stripper plate and the rubber. The connecting piece shaping punching die further comprises positioning columns arranged outside the guide columns and installed with the fixing plate in a matched manner. Positioning protrusions are integrally manufactured on the part, on the top of the outer side of a die hole, of the female die. According to the connecting piece shaping punching die, the periphery of a connecting piece is limited through the positioning protrusions in the punching process, and the connecting piece cannot be subjected to impact pressure so that the connecting piece cannot be deformed; and in addition, the service life of the rubber can be prolonged while it is guaranteed that positioning is accurate.
Description
Technical field
The present invention relates to a kind of perforating die, be specifically related to a kind of brace shaping perforating die, belong to technical field of mold.
Background technology
In prior art, brace perforating die complex structure, service life is short, operating difficulties in use procedure, can not accurately locate, and because this increasing labour intensity, reducing production efficiency, greatly have impact on product quality; China's application number 201210383621.3, disclose a kind of flange perforating die, comprise die shank, cope match-plate pattern, fixed head, guide pillar, piercing punch, lower bolster, die and stripper, die shank is arranged on cope match-plate pattern, fixed head is arranged on below cope match-plate pattern, and guide pillar is arranged between fixed head and stripper, and die is arranged on lower bolster, stripper is arranged on die, and piercing punch is arranged between fixed head and lower bolster.Flange perforating die of the present invention, Standard is simple, accurately, and long service life, in use easy to operate, accurate positioning, therefore reduces labour intensity, improves production efficiency; But in its punch process, easily cause that brace is out of shape, rubber easily follows the string, need secondary punching and the problem such as punching place is jagged.
Summary of the invention
(1) technical problem that will solve
For solving the problem, the present invention proposes a kind of brace shaping perforating die, brace punching quality is good, and it can not be caused to be out of shape.
(2) technical scheme
Brace shaping perforating die of the present invention, comprises die shank, and be installed on the cope match-plate pattern bottom die shank, and be arranged at the fixed head below cope match-plate pattern, and one end is arranged at the guide pillar bottom fixed head; And be arranged at the stripper of the guide pillar other end, and be arranged at the rubber between fixed head and stripper; And the die be arranged at below stripper, and be arranged at the lower bolster below die; And be arranged at inside guide pillar, and through the piercing punch of stripper and rubber; Also comprise and be arranged at guide pillar periphery, and coordinate the locating dowel of installing with fixed head, described die has been made into integration positioning convex in nib outside top.
Further, in described positioning convex, avris is set to the inner arc of fitting with brace.
Further, brace thickness is greater than to stripper end face distance bottom described locating dowel.
Further, described die and piercing punch are just to installation.
Further, described rubber is made up of polyurethane material.
Further, bottom described stripper, piercing punch periphery is provided with pressing block.
(3) beneficial effect
Compared with prior art, brace shaping perforating die of the present invention, drive stripper descending by cope match-plate pattern, when its come downwards to locating dowel reach stripper time, forcing press increase punching force, the now quick punching of piercing punch, and punch process is carried out spacing by positioning convex to brace periphery, make its pressure that is not hit cause distortion, it is while guarantee accurate positioning in addition, also can extend rubber service life.
Brace punching quality is good, and it can not be caused to be out of shape.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention.
Fig. 2 is plan structure schematic diagram of the present invention.
Detailed description of the invention
Brace shaping perforating die as depicted in figs. 1 and 2, comprises die shank 1, and is installed on the cope match-plate pattern 2 bottom die shank, and is arranged at the fixed head 3 below cope match-plate pattern, and one end is arranged at the guide pillar 5 bottom fixed head; And be arranged at the stripper 9 of the guide pillar other end, and be arranged at the rubber 4 between fixed head and stripper; And the die 8 be arranged at below stripper, and be arranged at the lower bolster 7 below die; And be arranged at inside guide pillar, and through the piercing punch 6 of stripper and rubber; Also comprise and be arranged at guide pillar periphery, and coordinate the locating dowel 11 of installing with fixed head, described die has been made into integration positioning convex 10 in nib outside top.
Further, in described positioning convex 10, avris is set to the inner arc of fitting with brace.
Further, brace thickness is greater than to stripper 9 end face distance bottom described locating dowel 11.
Wherein, described die 8 and piercing punch 6 are just to installation.Described rubber 4 is made up of polyurethane material.Bottom described stripper 9, piercing punch periphery is provided with pressing block 10.
Brace shaping perforating die of the present invention, drive stripper descending by cope match-plate pattern, when its come downwards to locating dowel reach stripper time, forcing press increases punching force, the now quick punching of piercing punch, and punch process is carried out spacing by positioning convex to brace periphery, makes its pressure that is not hit cause distortion, it is while guarantee accurate positioning in addition, also can extend rubber service life.
Embodiment recited above is only be described the preferred embodiment of the present invention, not limits the spirit and scope of the present invention.Under the prerequisite not departing from design concept of the present invention; the various modification that this area ordinary person makes technical scheme of the present invention and improvement; all should drop into protection scope of the present invention, the technology contents of request protection of the present invention, all records in detail in the claims.
