Description
Technical field
The present invention relates to punchings, more particularly to the process for improving plate punching precision coincidence rate.
Background technique
The machinery industries plate such as automobile, lathe is more and more, and the requirement to die quality can be higher and higher, die punching
Bedding-in, debug time directly influence the delivery cycle of mold.The coincidence rate of precision exists after preliminary market investigation discovery punching
35% or so, coincidence rate is lower, needs pincers worker to debug lapping-in, considerably increases debug time, directly affect the delivery of mold
Period.
Summary of the invention
The object of the present invention is to provide a kind of process for improving plate punching precision coincidence rate, which is improved
Punching precision, improves punching coincidence rate.
To achieve the goals above, the present invention provides a kind of process for improving plate punching precision coincidence rate, institutes
Stating process includes: that 1) plate to punching is fixed on punching machine；2) formed punch alignment procedures 1 are used) described on plate
To punching position and punching straight down；Wherein, the formed punch used in step 2) is along its long axis and short-axis direction
It is respectively arranged with long axis compensation and short axle compensation.
Preferably, the long axis compensation is 90% δ tg α -110% δ tg α；Wherein, δ is the thickness of plate, and α is formed punch position
In the punching drift angle on long axis direction relative to plate.
Preferably, the short axle compensation is 90% δ tg α ' -110% δ tg α '；Wherein, δ is the thickness of plate, and α ' is formed punch
Relative to the punching drift angle of plate on short-axis direction.
Preferably, 90 ° of 0≤α <.
Preferably, 90 ° of 0≤α ' <.
According to the above technical scheme, heretofore described process includes: that the plate to punching 1) is fixed on punching machine
On；2) formed punch alignment procedures 1 are used) described on plate to punching position and punching straight down；Wherein, in step 2)
The formed punch used is respectively arranged with long axis compensation and short axle compensation along its long axis and short-axis direction.By this process
The target for improving punching precision is reached, for the coincidence rate of precision 95% or so, coincidence rate is higher after punching, does not need pincers worker tune
Try lapping-in.
Other features and advantages of the present invention will the following detailed description will be given in the detailed implementation section.
Detailed description of the invention
The drawings are intended to provide a further understanding of the invention, and constitutes part of specification, with following tool
Body embodiment is used to explain the present invention together, but is not construed as limiting the invention.In the accompanying drawings:
Fig. 1 is a kind of schematic diagram of formed punch embodiment of punching on plate in the present invention.
Description of symbols
1 formed punch, 2 plate
Specific embodiment
Below in conjunction with attached drawing, detailed description of the preferred embodiments.It should be understood that this place is retouched
The specific embodiment stated is merely to illustrate and explain the present invention, and is not intended to restrict the invention.
In the present invention, in the absence of explanation to the contrary, it is included in the term " up and down, inside and outside front and back " etc.
The noun of locality only represents orientation of the term under normal service condition, or be those skilled in the art understand that be commonly called as, without answering
It is considered as the limitation to the term.
A kind of schematic diagram of formed punch 1 shown in Figure 1 embodiment of punching on plate 2, the process include:
1) plate 2 to punching is fixed on punching machine；2) 1 alignment procedures 1 of formed punch are used) described on plate 2 to punching position
And punching straight down；Wherein, the formed punch 1 used in step 2) is respectively arranged with length along its long axis and short-axis direction
Axis compensation and short axle compensation.
By above-mentioned process, the process includes: that 1) plate to punching is fixed on punching machine；2) make
With formed punch alignment procedures 1) described on plate to punching position and punching straight down；Wherein, used in the step 2)
The formed punch is respectively arranged with long axis compensation and short axle compensation along its long axis and short-axis direction.Reached by this process
The target of punching precision is improved, for the coincidence rate of precision 95% or so, coincidence rate is higher after punching, does not need pincers worker debugging and grinds
It closes.The cross section of formed punch 1 is generally elliptical, and rare occasion is circle, the compensation direction point of long axis compensation and short axle compensation
The not long axis direction along ellipse and short-axis direction right-angled intersection.
In this embodiment, size is more accurately compensated on long axis direction in order to further obtain formed punch 1, preferably
Ground, the long axis compensation is 90% δ tg α -110% δ tg α；Wherein, δ is the thickness of plate 2, and α is that formed punch 1 is located at long axis direction
On punching drift angle relative to plate 2.
In this embodiment, size is more accurately compensated on short-axis direction in order to further obtain formed punch 1, preferably
Ground, the short axle compensation is 90% δ tg α ' -110% δ tg α '；Wherein, δ is the thickness of plate 2, and α ' is that formed punch 1 is located at short axle side
Upwards relative to the punching drift angle of plate 2.
In this embodiment, size is more accurately compensated on long axis direction in order to further obtain formed punch 1, preferably
Ground, 90 ° of 0≤α <.
In this embodiment, size is more accurately compensated on short-axis direction in order to further obtain formed punch 1, preferably
Ground, 90 ° of 0≤α ' <.Under normal conditions, it is contemplated that easy for construction, the value of α ' is 0.
Such as: α=13 °, '=0 ° α, δ=0.8mm, tolerance 0-0.2, former 1 diameter of formed punch are 10.1mm.Practical punching
Diameter is 10.2, and punching is unsatisfactory for requiring, and need to be compensated.It is 10* that final compensated 1 diameter of formed punch is arranged after being computed
10.1 ellipse.The aperture finally rushed out after overcompensation is 10.1, meets aperture requirement, rushes compared to existing punching technology
Hole coincidence rate is high.
It is described the prefered embodiments of the present invention in detail above in conjunction with attached drawing, still, the present invention is not limited to above-mentioned realities
The detail in mode is applied, within the scope of the technical concept of the present invention, a variety of letters can be carried out to technical solution of the present invention
