Abstract
The invention provides a processing method for a cutting edge of a blanking die. The cutting edge of the blanking die comprises an outline of the cutting edge of the blanking die, wherein the outline of the cutting edge of the blanking die generates a line segment which is composed of a straight line segment and a circular-arc line segment by virtue of a decomposition spline, so that the outline is generated, and cutting edge seams of a terrace die and a die are guaranteed to be uniform. The processing method comprises the following steps: firstly, simplifying an outline process spline of the cutting edge of the blanking die to generate the straight line segment and the circular-arc line segment in segments, and controlling error between the generated straight line segment and the circular-arc line segment and the process spline to be within +/-0.0254mm; secondly, merging broken straight lines which possibly exist after simplifying, carrying out line segment increase fillet processing with a large included angle, and carrying out circular-arc straight linear processing with a very great radius and very short arc length; and thirdly, not merging the line segment which is composed of the straight line segment and the circular-arc line segment, selecting the line segment, generating the outline, and carrying out post-processing to generate processing data for processing the cutting edge of the blanking die. The cutting edge processed by the processing method has a die assembly rate of 100%.
Description
Technical field
The present invention relates to a kind of new method of blanking die cutting edge in machining, especially for the processing method of blanking die cutting edge.
Background technology
The speed goes that new model updates is fast, under the high-quality prerequisite of guarantee, requires that the manufacturing cycle of mould is also shorter and shorter.
Blanking die realizes contoured a kind of carrier as slab, its structure simple, intuitive, in machining and after assemble, ought to direct matched moulds, and manufacturing cycle also should comparatively other types mould shortening.In actual production manufacture process, the working position of blanking die, particularly cutting edge position, due to the quality of processing line, machining accuracy and bench skill level, often need bedding-in cutting edge, debug many wheels and just can reach matched moulds requirement.This not only affects quality and the outward appearance of cutting edge, also extends the manufacturing cycle of blanking die.This and the development trend of industry are that pole does not conform to.
The Mould Enterprise of current domestic advanced person, to the processing comprising blanking die trimming die cutting edge, also just rest on now the floor projection of 3 dimension curves and the stage of 2D programming, but to can direct matched moulds after the control in profile gap and processing, in earlier stage but too much do not studying.
As shown in Figure 1, 2, it is the profile generated with line transect 1, Tool-path Generation 2 is carried out owing to automatically line transect being divided into countless little straightways, cause 2 side tool rail points 3 inconsistent, the punch processed and cutting edge of die gap also inconsistent, can not be used for direct matched moulds, and after processing, cutting edge there is obvious cutter rail flex point.In Fig. 2, the lines of line transect 1 left and right sides and circle represent the cutter rail 2 and cutter rail point 3 that punch-die D6 cutter generates respectively.Contrasted by cutter rail 2, left and right sides cutter rail point 3 is different, not to process and puts in place simultaneously, also having the processed of maximum 0.083mm and amount by analyzing cutter rail 2 herein apart from the known maximum 0.084mm of having herein.The cutter rail point 3 of line transect 1 automatically generates, and has uncontrollable character.
Summary of the invention
The present invention, in order to can be consistent with die profile gap by the punch processed, prevents the cutter rail flex point of cutting edge, can directly debug by matched moulds, the special processing method proposing blanking die cutting edge.
Technical scheme of the present invention is for this reason, the processing method of blanking die cutting edge, comprise blanking die cutting edge contour, it is characterized in that: described blanking die cutting edge contour is by being decomposed into line transect, generate the line segment be made up of straightway and circular arc line segment, and generate profile thus, to ensure the punch that processes and cutting edge of die gap uniformity;
The steps include:
First, simplify blanking die cutting edge contour technique line transect, generate straightway or the circular arc line segment of segmentation, the straightway simultaneously herein generated and circular arc line segment and technique lines control errors are within ± 0.0254mm;
The second, the line segment merging, have mitre to the broken straight line that may exist after simplifying increases the very large but circular arc linearization(-sation) process that arc length is very short of fillet process, radius;
The line segment nonjoinder of the straightway three, after process and circular arc line segment composition, all chooses and carries out post processing after generating profile and generate process data in order to process blanking die cutting edge.
beneficial effect
New cutter rail, newly cutter rail point that the line segment of cathetus section of the present invention and circular arc line segment composition generates can control, and the line segment be made up of straightway and circular arc line segment, the new cutter rail point that both sides generate is always corresponding and consistent.
The cutting edge that the present invention processes, visually very smooth bright, there is no obvious cutter rail flex point; Can directly matched moulds debugging.
The blanking die cutting edge processed, no matter be detect or actual matched moulds result, cutting edge radius is evenly reasonable, does not black or burr phenomena.
Detect the blanking sample stamped out, error all controls in error range.
Compare the matched moulds rate that the blanking cutting edge processed with line transect has about 60%, the cutting edge matched moulds rate processed with this type line segment can reach 100%.

Detailed description of the invention
The present invention as shown in Figure 3,4.
The processing method of blanking die cutting edge, comprise blanking die cutting edge contour, described blanking die cutting edge contour, by decomposing line transect, generates the line segment be made up of straightway 4 and circular arc line segment 5, and generate profile thus, to ensure the punch that processes and cutting edge of die gap uniformity;
The steps include:
First, simplify blanking die cutting edge contour technique line transect, generate straightway 4 or the circular arc line segment 5 of segmentation, the straightway 4 simultaneously herein generated and circular arc line segment 5 and technique lines control errors are within ± 0.0254mm;
The second, the line segment merging, have mitre to the broken straightway 4 that may exist after simplifying increases the very large but circular arc line segment 5 linearization(-sation) process that arc length is very short of fillet process, radius;
Three, the line segment nonjoinder that the straightway 4 after process and circular arc line segment 5 form, all chooses and carries out post processing after generating profile and generate process data in order to process blanking die cutting edge.
The lines of figure cathetus section 4 and circular arc line segment 5 left and right sides and circle represent the new cutter rail 6 of punch-die D6 cutter generation and new cutter rail point 7 respectively, can be analyzed by new cutter rail point 7, in the point of intersection of two line segments, all create and produce cutter rail point, and analyze the spacing of each self-corresponding cutter rail, error is all after position very much, and the new cutter rail 6 that known line transect generates after being reduced to straightway 4 and circular arc line segment 5 is feasible.
