Description
Technical field
The utility model is on a kind of punch structure of cupping tool.
Background technology
The complicated high-strength plate stamping parts punch structure of geometric shape is by the way of monoblock cast processing, due to high intensity
Than more serious, common material can not meet die life requirement, extraordinary intensity material for die wear during plate stamping and forming
Expect that monoblock cast processing is relatively difficult, at the same the mould after monoblock cast processing can not detachable maintaining, this mode can not expire substantially
Foot uses and installation and maintenance requirement, and die cost is bigger, and cost is wasted than more serious.
Utility model content
The purpose of this utility model is to provide a kind of new punch structure, to realize that mould installion is easy to process, is manufactured into
This is low, and die face intensity is higher, and mould punching jig frequency is high, ensures die life, while mold work efficiency comparison is high.
To realize above-mentioned technical purpose, the utility model provides a kind of punch structure of cupping tool, and it includes：Upper mould
Seat, die shoe, punch-pin and blank holder, wherein：The punch-pin includes：Punch-pin face, body of punch and convex mould base, the punch-pin face are edge
Block structure, the body of punch and the convex mould base are integral casting forming, and the insert structure is fixedly installed in institute through bolt
State on body of punch.
As a further improvement, the convex mould base is fixedly mounted on the die shoe.
As a further improvement, when the upper bolster and the die shoe close, the blank holder compresses plate, described
Punch-pin face and cavity plate face compress the plate shaping.
As a further improvement, the punch-pin also has：The guide plate being longitudinally arranged, mould balance block and striker plate.
As a further improvement, it also includes：Transport connecting rod, clamping cap groove, mould protective plate and hanger.
Punch-pin face in the utility model is insert structure, is easy to process using extraordinary strength die material block insert type, convex
Die body and convex mould base can improve mould using common material casting pattern processing and the solid punch structure that is formed by connecting, this structure
Have service life, and improve production efficiency.

Embodiment
As illustrated in fig. 1 and 2, the utility model provides a kind of punch structure of cupping tool, and it includes：Upper bolster 1, lower mould
Seat 3, punch-pin and blank holder 2, wherein：The punch-pin includes：Punch-pin face 8, body of punch 9 and convex mould base 10, the punch-pin face 8 are edge
Block structure, the body of punch 9 and the convex mould base 10 are integral casting forming, and the insert structure is fixedly installed in through bolt
On the body of punch 9.
Punch-pin face in the utility model is insert structure, is easy to process using extraordinary strength die material block insert type, adds
Work is easy for installation, detachable maintaining is convenient, and body of punch and convex mould base are processed and are formed by connecting whole using common material casting pattern
Body punch structure, this structure can improve die life, and improve production efficiency.
As a further improvement, the convex mould base 10 is fixedly mounted on the die shoe 3.
As a further improvement, during upper bolster 1 and the die shoe 3 closure, the blank holder 2 compresses plate,
The punch-pin face 8 and cavity plate face compress the plate shaping.
As a further improvement, the punch-pin also has：The guide plate 11 being longitudinally arranged, mould balance block 12 and striker plate
13。
As a further improvement, it also includes：Transport connecting rod 4, clamping cap groove 5, mould protective plate 6 and hanger 7.
The high-strength plate inner panel die punch structure of the geometric space complex contour of the cupping tool, the structure die face use
Specific intensity insert structure makes, and punch-pin face part is installed on die shoe after being made using special material insert, convex mould base and convex
Die body is cast out using monoblock cast pattern, and block insert type punch-pin face structure can both be protected using the installation of the structures such as bolt, this structure
The working strength of mould die face is demonstrate,proved, the convenience of fabrication and installation can be ensured again, ensures the working life of mould, improves the work of mould
Make efficiency.
The cupping tool punch-pin overall structure as shown in figure 1, lower mould figure (punch-pin) as shown in Fig. 2 punch structure is
Three parts, respectively punch-pin face insert, body of punch, convex mould base, this punch structure can ensure complicated stamping high-strength plate into
Shape intensity requirement, while ensure the convenient and reliable of Making mold installation, mould is overhauled conveniently, mold work efficiency high, and can
To ensure die life.
The utility model uses block insert type die face structure, body of punch and convex mould base monoblock cast pattern, mould installion processing
More convenient, for manufacturing cost than relatively low, die face intensity is higher, and mould punching jig frequency is high, ensures die life, while mould
It is higher to have operating efficiency.Using monoblock cast and block insert type structure, ensure mould use intensity, and improve mould and use the longevity
Life, mould production efficiency greatly improve.
When mould closes, blank holder suppresses plate, and punch-pin face and cavity plate face pressure are lived plate and shaped, and the structure can ensure
The stamping die face intensity requirement of complex appearance high-strength plate, while the convenience of mould release installation and maintenance can be ensured, carry
High mold work efficiency, ensure the mold work life-span.
It should be appreciated that the utility model scope of the claimed is not limited to non-limiting embodiments, it should be understood that non-limiting reality
Scheme is applied to illustrate as just example.The desired substantive protection domain of the application is more embodied in independent claims
The scope of offer, and its dependent claims.
