Abstract
The invention discloses a kind of Toyota parking brake support fine punching method, comprise the steps: that (1) uses PVD coating technique to form one layer of TiCN film at punch head surface；(2) using small-gap suture stamping-out allowance, reduction is collapsed angle and tear-strap size as far as possible, reduces the size reduction of collapse angle and tear-strap；(3) use secondary and three essences to cut, use small-gap suture and little cutting output.The invention have the advantage that owing to minimum blade clearance makes blanking pressure be multiplied, frictional force between product and drift is significantly increased, it is easily generated high temperature and Integrated Chip, the life-span making drift drastically declines, use the drift of routine, life-span at most only has hundreds of time, makes the parking brake support brightness being obtained by the present invention high, and drift reaches more than 200,000 times service life simultaneously.
Description
Technical field
The invention belongs to metal material punch press process technical field, particularly to parking brake support fine punching side of a kind of Toyota
Method.
Background technology
Stamping-out is utilize punch die to make portion of material or process part processing separate with another part material, work (sequence) part or waste material one
Plant stamping procedure.Stamping-out is that shearing, blanking, punching, punching lack, jet-bedding, cutting, chisel are cut, trimming, cut tongue, cut, trimming etc. separates
The general name of operation.
Required form and the part of size or the process for stamping of blank is isolated from plate.Stamping-out is the sword utilizing punch die
Mouth makes plate produce detrusion along certain contour line and separate.The ratio maximum that stamping-out is shared in punching production.In punching
During sanction, in addition to the metal near shearing wheel profile, plate itself does not produce plastic deformation, so by flat board punch press process
Part remain a flat shape.
Fine punching is also known as small-gap suture stamping-out, compared with common stamping, is characterized in taking small round corner cutting edge and the least
Rush mill gap.Fig. 1 is Toyota's parking brake support, because needing riveted with parking brake bound fraction, it is desirable to the profile tolerance of riveted part isAnd section is the euphotic belt of more than 80%.Thinking routinely, need to use essence cutting process:
1, need to use Special punch, purchase special equipment, cost is high, and utilization rate is low；
2, the profile of tooth edge pressing mould structure that fine is special is used: structure is complicated, and operation is many, and cost is high, and waste of material compares
Many；
3, due to minimum blade clearance, blanking pressure being multiplied, the frictional force between product and drift significantly increases
Adding, be easily generated high temperature and Integrated Chip so that the life-span of drift drastically declines, use the drift of routine, the life-span at most only has hundreds of time,
The new method improving the drift life-span must be used.
Summary of the invention
The present invention seeks to overcome background technology not enough, the technical scheme that the present invention provides is:
A kind of Toyota parking brake support fine punching method, comprises the steps:
(1) PVD coating technique is used to form one layer of TiCN film at punch head surface；
(2) stamping-out for the first time；
(3) essence is cut for the second time；
(4) essence is cut for the third time.
Further, it is 2-4 μm that step (1) forms the thickness of TiCN film, and drift surface hardness reaches 3000-3500HV, rubs
Wipe coefficient 0.5.
Further, step (2) stamping-out for the first time stays cutting output 0.7mm, blade clearance to be reduced to 0.05mm.
Further, step (3) essence for the second time cuts cutting output 0.5mm, blade clearance 0.02mm.
Further, step (4) essence for the third time cuts cutting output 0.2mm, blade clearance 0.02mm.
Holding pad binder uses large-scale nitrogen spring binder, it is ensured that pressure-plate-force, makes place of incision material be in three-dimensional and cuts
Shearing stress state, reduces stamping-out deformation.
Owing to minimum blade clearance makes blanking pressure be multiplied, the frictional force between product and drift is significantly increased,
Being easily generated high temperature and Integrated Chip so that the life-span of drift drastically declines, use the drift of routine, the life-span at most only has hundreds of time, must
The new method improving the drift life-span must be used
Compare through experiment and feel free to try, punch head surface is used PVD coating technique, forming one layer at punch head surface
TiCN film so that drift surface hardness reaches 3000-3500HV, coefficient of friction is 0.5, and uses Special punching force feed aborning
It is lubricated.Through reality application measuring and calculating, the drift life-span reaches more than 200,000 times, the non-plated film life-span that compares improve 10 times with
On, fully meet requirement of both production and cost.
PVD is the abbreviation of English Physical Vapor Deposition, and the Chinese meaning is physical vapour deposition (PVD), refers to
Under vacuum, make, by the method for physics, the film preparing technology that material is deposited on workpiece to be plated.
The invention have the advantage that owing to minimum blade clearance makes blanking pressure be multiplied, between product and drift
Frictional force is significantly increased, and is easily generated high temperature and Integrated Chip so that the life-span of drift drastically declines, and uses the drift of routine, and the life-span is
Much the most hundreds of time, making the parking brake support brightness being obtained by the present invention high, drift reaches 200,000 times service life simultaneously
Above；Due to strong pressure and minimum blade clearance, suitable cutting output, make the deformation of product place of incision minimum, section light
Bright band is more than 90%.

Detailed description of the invention
Embodiment 1
A kind of Toyota parking brake support fine punching method, comprises the steps:
(1) PVD coating technique is used to form one layer of TiCN film at punch head surface；The thickness forming TiCN film is 2-4 μm, punching
Head surface hardness reaches 3000-3500HV, coefficient of friction 0.5.And use Special punching force feed to be lubricated aborning.Through reality
Application is calculated, and the drift life-span reaches more than 200,000 times, and the non-plated film life-span that compares improves more than 10 times,
(2) stamping-out for the first time；Stamping-out stays cutting output 0.7mm, blade clearance to be reduced to 0.05mm for the first time.
(3) essence is cut for the second time；Essence cuts cutting output 0.5mm, blade clearance 0.02mm for the second time.
(4) essence is cut for the third time；Essence cuts cutting output 0.2mm, blade clearance 0.02mm for the third time.
Due to strong pressure and minimum blade clearance, suitable cutting output, make the deformation of product place of incision minimum, section
Euphotic belt is more than 90%.Holding pad binder uses large-scale nitrogen spring binder, it is ensured that pressure-plate-force, makes place of incision material be in
Three-dimensional shear state, reduces stamping-out deformation.
According to above-mentioned technique, design corresponding mould trial-production, it is fully achieved design requirement, has produced up to a million after putting into production
Secondary.This mould production efficiency is high, simple and reliable for structure, and mold repair is convenient, and low cost has very Gao Jing in like product mould
Strive power.
The foregoing is only presently preferred embodiments of the present invention, it is impossible to be considered for limiting the present invention, all the present invention's
Any amendment, equivalent and the improvement etc. made in spirit and principle, should be included in the present invention patent covering scope it
In.
