Description
Technical field
The utility model is related to hole flanging mechanism technical field, specifically a kind of hole flanging mechanism.
Background technology
Hole flanging, as by bore edges translate into erect side, it is different from punching, punching be by waste material along closed outline from
A kind of stamping procedure detached on material or process part processing, obtains the hole of needs on material or process part processing, and hole flanging is along endoporus week
Enclose a kind of stamping procedure that material is translated into edge-on flange.In the prior art, generally hole flanging is realized by two procedures, i.e., in advance
Punching and hole flanging.
Punch, the metal parts on hole flanging mechanism tool in machine tool, is called and rushes stick, red needle or punching pin, be peace
Continuous stamping punching press is carried out on hole flanging mechanism tool and thrusts operation, makes machined material that separation or plastic deformation occur, to
Obtain required finished product or semi-finished product.
Punch is also punch-pin, upper mold, formpiston, red needle etc., and punch is divided into as A types punch, T-type punch, special-shaped plunger chip；Punching
Head is mounted in the metal parts on hole flanging mechanism tool, is in direct contact applied to material, so that material is deformed upon, cut material
Material；Mold and punching head generally uses high-speed steel and wolfram steel etc. to be used as material, there is high-speed steel punch and wolfram steel punch etc., and high-speed steel is
Most common material, there are commonly CR12, CR12MOV, asp23, skd11, skd51, skd61 etc., wolfram steel material is generally used
On more demanding punching and shearing die.
In the prior art, the common mode of production is used carries out close-fitting, stationary phase with the ball-type punch to sprout and fixed plate
Hole flanging is carried out to position.Such technique productions have following defect：1, more demanding to the ball head for punching of sprouting, not such as machining on spherical end
When, will cause hole flanging damage and it is unqualified；2 and mold when assembling because punch and fixed plate are to be interference fitted to be easy to cause
Punch tilts (being more easy to occur in production process), keeps product unqualified；3, sprout punch flange when, material and punch extruding have
Certain material falls back, the punch that sprouts product waste material is more, and hole flanging size is unstable；4, the punch damaged is also not easy to replace.5, it takes out
The service life of bud punch is short.
