Workpiece on flitch, it is to avoid in punch process, workpiece deviates commitment positions.
Described multiple upper mould is divided into two groups, and upper mould odd number from left to right is first group, upper mould idol from left to right
Several be second group, first group and second group of active length differs a thickness of workpiece, in actual punch process, first group
Carry out operation in two batches with second group, be first group of upper punch hole first, second group of upper punch hole afterwards, applicant passes through reality
, so that total stamping press halves, in prolongation, the service life of mould, reaches economical and energy saving for operation and theoretical reckoning, so operation
Purpose.
The cutting edge of described upper mould carries out grinding with the gradient of thickness of workpiece 1/10th and becomes to the diclinic caving in
Face, applicant passes through actual job and theoretical reckoning, and such structure not only can reduce punching power, can obtain bright and clean simultaneously
Hole so that stripping force is reduced to almost zero.
Preferably, described guide pillar includes guide pillar body, and guide pillar body is provided with dimpled grain, and dimpled grain is inlaid with solid lubrication
Material, the thickness of solid lubricant is more than 0.5mm, and compared with prior art, this structure possesses self-lubricating function, in mould fortune
Row initial stage, and refueling when not having lubricating oil not in time, can voluntarily provide lubrication, reduce between guide pillar and guide pin bushing due to
Dry friction and the abrasion that produces, improve the service life of whole set of die, meet the use requirement of long-life, high-precision mold.
Preferably, about described lower mold fixed plate, two ends are provided with locating piece, and locating piece assists multiple rubber pressing rollers
Workpiece is positioned, be further ensured that workpiece in process in set position so that the workpiece produced meets opens
Begin to need.
Preferably, the material of described upper mould is Crl2, and the material of described lower mould is T10 steel, described guide pillar
Material with guide pin bushing is GCr15 steel so that this mould has higher hardness, uniform tissue, good wearability, high
The performances such as contact fatigue.
It is an advantage of the invention that：
