Second tool half includes at least one first contact surface, at least one second contact surface, at least one second cutter device, until
A few third cutter device, and be arranged in this second and third cutter device between gap.
Background technique
Become known for cutting the different cutting techniques of workpiece from the prior art.Workpiece is usually metal plate or (metal plate)
Slab usually carries out multiple cutting operation in process of production.Before producing workpiece, to determine which kind of which kind of machine cut with
Segmentation method is most suitable for these cutting operations.These cutting operations include for example shearing or being cut by laser.
The purpose of cutting technique is to produce the cut edge of high-quality as far as possible, it is characterized in that smooth section ratio is big,
Burr is few or does not have burr, flange or fracture, and section extension is as vertical as possible.
Depending on material and tool design, these requirements can be more or less better meet.It is soft in shear history
And tough and tensile material tends to the smooth section that higher proportion is generated in vertical section extends, and is broken few.But this
It is using higher flange and glitch amplitude as cost.
High-intensitive and fragile material is then opposite.In this case, smooth section ratio is relatively small, and be broken ratio compared with
Greatly, this part results in non-perpendicular cut surface and fracture.However there is few flange and seldom burr.If section is thick
It is rough, then this crack at edge sensibility in addition increasing cut edge.
Hardening in edge mainly appears in soft or flexible material.This is big along edge and to its depths
Measure the result of dislocation variation.
About state-variable, seek small cutting gap and low cutting force.But due to the transverse direction in cutting process
Power will lead to gap and become larger, and therefore, especially for open cutting, these are difficult to realize.Although this will lead to smaller really
Cutting force, but will lead to bigger flange, burr and inclined section.
High-intensitive and fragile material cutting is proved to be especially difficult.Since the yield limit of steel is very high,
Process power greatly increases, to considerably increase the load of cutting tool.Here, especially its cutting edge and table adjacent thereto
The load in face (end face and circumferential surface) is larger.As time goes by, cutting edge rust and/or fracture, and end face and circumferential surface
Material become fatigue due to continuous stress alternation, and wear more next in conjunction with having abrasive cutting material
It is more serious.
In order to offset these influences, a large amount of research and measure have been carried out to the cutting process of high strength steel.It therefore, can be with
It is contemplated that changing the cutting angle of blade, change the geometry of cut edge, the precut edge of rear trimming, or use
Accurate cutting.But it can not satisfactorily realize and realize low-level abrasion while the trimming of high quality.
Summary of the invention
Therefore, the purpose of the present invention is to propose a kind of method and apparatus for cutting workpiece, by this method and equipment,
The abrasion of cutter device is especically reduced using it, and at the same time improving or at least without the quality for deteriorating cut edge.
According to the present invention, foregoing purpose is achieved in this way, that is, the first cutter device has on its end face towards workpiece
There are two cutting edges, so that producing dual notch by means of the cutter device during cutting operation.
In order to clamp workpiece, the two sides of workpiece to be cut are fixed on Workpiece Holders and contact surface in this way
Between, it is pulled out from the region for being not required to cutting so that substantiallying prevent workpiece in cutting process.Preferably, step is being clamped
During rapid, the first cutter device is not yet contacted with workpiece.Moreover it is preferred that two Workpiece Holders are synchronously moved to workpiece
Above and as the component of Rigid interconnection work.First cutter device is arranged between two Workpiece Holders, so as to
Carry out dual notch.Here, the clamping force of Workpiece Holders is determined in this way, that is, is almost prevented workpiece never
It is pulled out in the region cut.
In order to generate dual notch, arrangement two is identical preferably on the end face towards workpiece of the first cutter device is cut
Sword is cut, so that the cut quality of two cuttings is essentially identical.In addition, the cutting basil of each cutting edge of the first cutter device is excellent
Selection of land is greater than 90 °, and the cutting basil is most preferably in the range of about 98 °.Within the scope of this invention, dual notch refers to by that
The cutting of this separated two cutting lines composition.
In the case where dual notch, the cross force generated in cutting process acts on opposite to each other, thus at least very
It cancels out each other in big degree, in the first cutter device or act on almost without Lateral Force and be arranged in the first cutting dress
On the cutting edge set.Second cutter device and third cutter device similarly so that there is no that cross force also acts on
On these parts.
Here, second and third cutter device be formed as blade, or be formed to have the second tool being connected thereto
The blade of the contact surface of half portion.If second and contact surface of the third cutter device with adjoining, substantial horizontal
Orientation, wherein in the transitional region to the first and second contact surfaces, adjacent contact surface and the first and second contact tables
In face of standard.
By having reduced or eliminated the cross force acted on cutter device, therefore substantially reduce on tool and tool
Adjacent surface (end face and circumferential surface) on edge loading, it is more preferable so as to cause longer cutter life and workpiece to be cut
Cut quality.
After cutting, the band of workpiece to be cut cut out is fallen into gap, and the band cut out is in the cutting operation phase
Between be located at cutter device two cut edges between.Since cutting waste material preferably has narrow width, only have lost
Very small amount of material.After completing cutting operation, the first tool half is removed from workpiece, so as to cut
Two parts of workpiece are removed.
Preferably, in the method, the second tool half of cutter device does not move.
The material high-intensitive and frangible particularly suitable for cutting according to the method for the present invention, but can be used for cutting soft
And tough and tensile material.
For example, workpiece is made of steel, especially high strength steel.For example, workpiece is the steel workpiece of cold forming or thermoforming.
It has been observed that especially have up to 1900MPa or more tensile strength workpiece can by according to the method for the present invention come
Processing.Preferably, it is particularly possible to the metal sheet with a thickness of 0.1mm to 5mm is processed by according to the method for the present invention.
First tool half and the preferably upper tool half of the first cutter device and upper cutter device.Second tool half,
Second cutting tool and third cutting tool are preferably lower tool half, the first lower cutting device or the second lower cutting device.The
One and second workpiece retainer be preferably the first and second lower depressors.First and second contact surfaces of the second tool half are preferred
It is the first and second support surfaces.If second and/or third cutter device be formed to have the second tool being connected thereto
The blade of the contact surface of half portion, then the first of the second tool half and/or the second contact surface can not be with workpiece to be cut
Contact, but especially second and/or the contact surface of third cutter device be in contact with it.
