Referring to fig. 1, fig. 1 is a schematic diagram of an intelligent design method of a trimming insert mounting base plate according to some embodiments of the present application, for generating a mounting base plate 92 of a trimming insert 90 of a trimming and punching die, comprising the steps of:
A1. Acquiring a cutting edge body model composed of a plurality of pre-generated cutting edge bodies 91; the bottom surfaces of the cutting edge bodies 91 are coplanar (i.e., the bottom surfaces of the cutting edge bodies 91 are on the same plane);
A2. Taking the bottom surface of the cutting edge bodies 91 as a reference surface, and identifying the conformal edge line in the contour line of each cutting edge body 91 on the reference surface; the conformal edge is the closest offset line to the projection of the trimming line segment 93 of the edge body 91 on the reference plane;
A3. according to the positions of the cutting edge bodies 91, the ends of the conformal edges of the cutting edge bodies 91 are adjusted so that the ends of the conformal edges adjacent to other conformal edges extend outwards;
A4. Generating an envelope edge line of the cutting edge body model in the reference plane; the envelope edge line and each edge body 91 are provided with a space;
A5. Generating a mounting base plate base surface of each cutting edge body 91 according to the envelope edge line and the shape following edge line of each cutting edge body 91;
A6. stretching the base surfaces of the mounting base plates to form mounting base plates 92 of the cutting edge bodies 91, and fusing the mounting base plates with the cutting edge bodies 91 to obtain the corresponding trimming insert 90.
According to the method, on the basis of the pre-generated cutting edge body model, the mounting base plate 92 of the trimming insert 90 can be generated through simple operation, automatic generation of the mounting base plate 92 of the trimming insert 90 is realized, the mounting base plates 92 do not need to be designed manually one by one, and the design efficiency is greatly improved.
The edge body 91 in the edge body model is a three-dimensional body generated by operations such as biasing, sweeping, stretching and the like based on the corresponding trimming line segment 93, and the specific generation process is not limited herein because the specific generation process does not belong to the key technology of the present application.
For example, fig. 4 shows a perspective view of an exemplary cutting edge body 91, wherein the C-plane is the bottom surface of the cutting edge body 91, and wherein the trimming line segment 93 is a three-dimensional curve. In general, a reference coordinate system XYZ is established in a previously generated edge body model, in which the edge body 91 in the edge body model is distributed around the origin of the reference coordinate system XYZ, the bottom surface of the edge body 91 is parallel to the XY plane of the reference coordinate system XYZ (i.e., perpendicular to the Z axis), so that the reference plane is parallel to the XY plane of the reference coordinate system XYZ, and the point on the bottom surface of the edge body 91 is generally the point with the largest Z coordinate or the smallest Z coordinate among the surface points of the edge body 91 (the point on the bottom surface is the point with the largest Z coordinate if the edge body 91 is generated to stretch in the positive Z direction, and the point on the bottom surface is the point with the smallest Z coordinate if the edge body 91 is generated to stretch in the negative Z direction), and therefore, in step A2, the bottom surface of the edge body 91 can be identified by:
The center points of all the planar surfaces of the edge body 91 are extracted, and the planar surface with the largest Z coordinate or the smallest Z coordinate of the center point is taken as the bottom surface of the edge body 91.
The contour line of the cutting edge 91 on the reference plane (i.e., the contour line of the bottom surface) includes two curved edges and two straight edges, one straight edge is connected between the first ends of the two curved edges, and the other straight edge is connected between the second ends of the two curved edges. Wherein, both curves are bias lines of projection of the trimming line segment 93 of the cutting edge body 91 on the reference plane. For example, in fig. 5, the contour line of the edge body 91 on the reference plane includes a curve L1, a curve L2, a straight line L3, and a straight line L4, wherein the curve L1 is a curve closest to the projection of the trimming line segment 93 on the reference plane, and thus, the curve L1 is a conformal edge line of the edge body 91.
Note that, fig. 5 shows a perspective view of the edge body 91 without the scrap cutter portion, and actually the edge body model further includes the edge body 91 with the scrap cutter portion, for example, the edge body D in fig. 7 is the edge body 91 with the scrap cutter portion, where the D portion is the scrap cutter portion of the edge body 91, and for this edge body 91, a line segment located at the scrap cutter portion along the contour is referred to as a scrap cutter line (for example, a line segment e extending longer upward in fig. 7 is a scrap cutter line).
Wherein, the step of identifying the conformal edge line in the contour line of each edge body 91 on the reference plane in the step A2 includes:
A201. extracting two curved edges in the contour line of the cutting edge body 91 on the reference surface, and marking the two curved edges as alternative curved edges;
A202. respectively calculating the distances between the midpoints of two alternative curved edges of the cutting edge body 91 and the midpoint of the trimming line segment 93 of the cutting edge body 91, and recording the distances as midpoint distances;
A203. And taking the alternative curved edge corresponding to the smaller value of the two midpoint distances as a conformal edge.
The conformal edge line can be simply and accurately identified in the above manner according to the structural characteristics of the edge body 91.
Specifically, step A3 includes:
A301. Classifying the end points of the conformal edges of the cutting edge bodies 91 according to the positions of the cutting edge bodies 91;
A302. According to the end point classification result, the end parts of the conformal side lines are adjusted to enable the end parts of the conformal side lines adjacent to other conformal side lines to extend outwards (as the edge bodies 91 in the edge body model are distributed around the origin of the reference coordinate system XYZ, on the reference plane, the bottom surfaces of the edge bodies 91 are distributed around the Z axis of the reference coordinate system XYZ, and outwards means towards the direction far away from the Z axis).
By extending the ends of each conformal rim outward adjacent to the other conformal rims, interference between subsequently created individual mounting plates 92 is advantageously avoided (see below for a specific analysis process).
Wherein, the end points of the conformal side line comprise three types: class 1 endpoints, class 2 endpoints, and class 3 endpoints; the class 1 end points are end points without adjacent cutting edge bodies 91 in the adjacent areas; the class 2 end points are the end points of the non-scrap cutter portions of the adjacent cutting edge bodies 91; the class 3 end points are the end points of the scrap knife portion having adjacent edge bodies 91 in the adjacent region. The adjacent area of one end point refers to a circular area with a preset length (which may be set according to practical needs, preferably, the preset length is not less than the thickness of the cutting edge body 91, so as to more effectively avoid interference between the adjacent mounting base plates 92, and the thickness of each cutting edge body 91 is generally the same, but not limited thereto) as a radius. For example, the classification results of the end points of the conformal edges of the partial edge bodies 91 are shown in fig. 6, and it can be seen that the other edge bodies 91 other than the edge body 91 to which they belong are not present near the class 1 end point (in the adjacent region), the other edge bodies 91 other than the edge body 91 to which they belong are present near the class 91,2 end point and are adjacent to the non-scrap blade portion of the other edge bodies 91, and the other edge bodies 91 other than the edge body 91 to which they belong are present near the class 3 end point and are adjacent to the scrap blade portion of the other edge bodies 91.
Further, step a302 includes:
extending outwards a first preset distance along the thickness direction of the belonged cutting edge body 91 at the class 2 end point of the conformal edge;
extending outwardly a first predetermined distance in a direction parallel to the scrap knife line of the adjacent edge body 91 at the class 3 end points of the conformal edge line; the scrap cutter line is a line segment located at the scrap cutter portion along the contour edge.
The end having the class 1 end point is not subjected to adjustment processing.
The first preset distance may be set according to practical needs, for example, equal to the thickness of the cutting edge 91, but is not limited thereto.
For example, fig. 7 shows the end adjustment result of the conformal edge line (the thickened black line in the drawing) of a part of the edge body 91, and in combination with fig. 6, the left end point of the conformal edge line of the leftmost edge body 91 is a class 1 end point, without adjustment treatment, the right end point is a class 2 end point, so as to extend outwards by a first preset distance along the thickness direction of the edge body 91 to which the edge body belongs; the left end point of the conformal edge line of the second edge body 91 from the left is a class 2 end point, so as to extend outwards by a first preset distance along the thickness direction of the associated edge body 91, and the right end point is a class 3 end point, so as to extend outwards by a first preset distance along the direction parallel to the scrap knife line of the adjacent edge body 91; the left end point of the conformal edge line of the third edge body 91 from the left is a 1-class end point, the adjustment is not performed, and the right end point is a 3-class end point, so that the first preset distance extends outwards along the direction parallel to the waste cutter line of the adjacent edge body 91; and so on.
In some embodiments, step A4 comprises:
A401. Generating a minimum rectangular frame envelope frame which surrounds all conformal side lines (the conformal side lines after the end part is adjusted) on the reference surface;
A402. And stretching the envelope frame of the minimum rectangular frame in the length direction and the width direction respectively to obtain envelope edges.
The method of generating the minimum rectangular frame envelope frame is the prior art, and is not described in detail herein.
The stretching lengths of the minimum rectangular frame envelope in the longitudinal direction and the width direction may be the same or different. The specific stretching length can be set according to actual needs.
The position of the enveloping edge corresponds to the position of the outermost edge of the mounting base plate 92, and the enveloping edge is obtained in the above manner, so that the outermost edge of the finally obtained mounting base plate 92 is ensured to be outside the outermost point of the cutting edge body 91, and the whole cutting edge body 91 is supported by the mounting base plate 92, thereby providing enough supporting force for the cutting edge body 91 and avoiding the deformation of the cutting edge body 91 in the working process.
For example, in fig. 8, the rectangular frame f is a minimum rectangular frame envelope frame, the rectangular frame g is an envelope edge, and in fig. 8, the minimum rectangular frame envelope frame has a longer stretch length in the longitudinal direction than in the width direction.
In some embodiments, step A5 comprises:
A501. if a conformal side line (the conformal side line after the adjustment end part) has a first end point, connecting a point on the envelope side line closest to the first end point with the first end point (connected by a straight line) to obtain a connecting side line of the conformal side line; the first endpoint is a class 1 endpoint;
A502. if a conformal side line (the conformal side line after the adjustment end part) has a second end point, connecting a point on the envelope side line closest to the second end point with the second end point (connected by a straight line) to obtain a connecting side line of the conformal side line; the second endpoint is an endpoint extending from the class 2 endpoint;
A503. If a conformal edge (which refers to a conformal edge after the end is adjusted) has a third end point, connecting a projection point of the third end point projected outwards on the envelope edge along a direction parallel to the scrap cutter line of the adjacent cutting edge body 91 and the third end point (which is connected by a straight line) to obtain a connecting edge of the conformal edge; the third endpoint is an endpoint extending from the class 3 endpoint;
A504. the mounting base plate base surface of the cutting edge body 91 to which the conformal side line belongs is surrounded by the conformal side line, the two corresponding connecting side lines and the line segment on the enveloping side line between the two corresponding connecting side lines.
For example, fig. 9 shows the result of generating the base surface of the mounting base, for the second edge 91 from the upper left in the drawing, the left end point of the conformal edge after the end is adjusted is the second end point, so that the corresponding connecting edge is the perpendicular line from the second end point to the upper edge of the enveloping edge, and the right end point is the third end point, so that the corresponding connecting edge is the line from the projection point of the third end point projected outwards on the upper edge of the enveloping edge along the direction parallel to the waste knife line of the adjacent edge 91 to the third end point; for the third edge 91 from the upper left in the figure, the left end point of the shape-following edge after the end is adjusted is the first end point, so that the corresponding connecting edge is the perpendicular line from the first end point to the upper edge of the envelope, and the right end point is the third end point, so that the corresponding connecting edge is the line from the projection point of the third end point projected outwards on the upper edge of the envelope to the third end point along the direction parallel to the scrap cutter line of the adjacent edge 91; and so on. It can be seen from the figure that if the end of the conformal edge is not adjusted, and the end point of the conformal edge is directly connected with the nearest point on the envelope edge to form a connecting edge, it is easy for the connecting edge to pass through the adjacent edge bodies 91 (for example, the right end of the first edge body 91 from the upper left directly upwards draws a vertical line to pass through the second edge body 91 from the upper left, and the right end of the second edge body 91 from the upper left directly upwards draws a vertical line to pass through the third edge body 91 from the upper left), thereby causing interference between the adjacent trimming inserts 90; the end part of the conformal side line is adjusted, so that the situation can be effectively avoided.
In practice, after step A504, the mounting substrate base surfaces may also be displayed so that the user manually adjusts the edge lines of each mounting substrate base surface. I.e. after automatically generating the mounting base surface, allows manual adjustment of the contour of each mounting base surface. For example, the left side line of the two floor bases in the upper left corner and the lower left corner in fig. 9, and the right side line of the two floor bases in the upper right corner and the lower right corner are both manually adjusted side lines.
Specifically, step A6 includes:
A601. Stretching each mounting base surface in a direction perpendicular to the reference surface to generate a corresponding mounting base 92;
A602. The respective mounting base plates 92 and the corresponding edge bodies 91 are boolean-sum-operated to obtain the corresponding trimming inserts 90.
In a601, the mounting base surface may be stretched in a direction opposite to the edge body 91, or may be stretched in a direction opposite to the edge body 91, where the stretching height is a preset height, and the preset height may be set according to actual needs.
From the above, the intelligent design method of the trimming insert mounting base plate obtains a cutting edge body model composed of a plurality of pre-generated cutting edge bodies 91; the bottom surfaces of the cutting edge bodies 91 are coplanar; taking the bottom surface of the cutting edge bodies 91 as a reference surface, and identifying the conformal edge line in the contour line of each cutting edge body 91 on the reference surface; the conformal edge is the closest offset line to the projection of the trimming line segment 93 of the edge body 91 on the reference plane; according to the positions of the cutting edge bodies 91, the ends of the conformal edges of the cutting edge bodies 91 are adjusted so that the ends of the conformal edges adjacent to other conformal edges extend outwards; generating an envelope edge line of the cutting edge body model in the reference plane; the envelope edge line and each edge body 91 are provided with a space; generating a mounting base plate base surface of each cutting edge body 91 according to the envelope edge line and the shape following edge line of each cutting edge body 91; stretching the base surface of each mounting base plate to generate a mounting base plate 92 of each cutting edge body 91, and fusing the mounting base plate 92 with each cutting edge body 91 to obtain a corresponding trimming insert 90; therefore, the automatic generation of the mounting bottom plate of the trimming insert can be realized, and the design efficiency is improved.
