Stamping die rubber cushion intelligent stock layout method and system

Abstract

The invention provides a stamping die rubber cushion intelligent stock layout method and system. The method includes the steps of defining the cutter edge contour line, the die stamping direction, gaps between adjacent rubber cushions, and the initial point of the cutter edge contour line, and selecting one from various preset rubber cushion specifications; measuring the length of the cutter edge contour line; calculating the number of required rubber cushions; equally dividing the cutter edge contour line according to the number of the rubber cushions to obtain a plurality of equally-dividing points, wherein the initial point serves as the first equally-dividing point; generating the corresponding rubber cushion at each equally-dividing point, wherein the center of the bottom of each rubber cushion is located at the corresponding equally-dividing point, the rubber cushions are of the previously-selected rubber cushion specification, the direction from the bottom to the top of each rubber cushion is parallel to the die stamping direction. By means of the stamping die rubber cushion intelligent stock layout method and system, the rubber cushions can be rapidly and automatically distributed, the traditional problem of distributing rubber cushions is thoroughly solved, and design efficiency of stamping dies is greatly improved.

Description

technical field [0001] The invention relates to the layout design of rubber pads of stamping dies, in particular to an intelligent layout method and system for rubber pads of stamping dies. Background technique [0002] In the stamping die, a row of rubber pads must be evenly arranged around the trimming knife according to the shape of the edge of the trimming knife. When the material is cut, these rubber pads play a role of cushioning and pressing. The arrangement of rubber pads in the stamping die has the following characteristics: [0003] 1) The rubber pads are small in size and large in number. For example, the total number of rubber pads in the stamping die surrounding the outer panel on one side can reach 400 to 600; [0004] 2) Position constraints are difficult, and the arrangement of rubber pads is required to be strictly conformal to the shape, while the shape of the trimming knife of the stamping die is mostly arc-shaped or irregular, and it is difficult to accu...

Problems solved by technology

[0004] 2) Position constraints are difficult, and the arrangement of the rubber pads is required to follow the shape strictly. However, the shape of the trimming knife of the stamping die is mostly curved or irregular, and it is difficult to accurately control the angle. The position of the rubber pad is required to be evenly arranged according to the shape of the trimming knife Cloth, its positioning is also difficult to control;

[0005] 3) It is difficult to update the shape of the layout. Once the shape of the trimming line changes, or the specification of the rubber pad needs to be replaced, the position and angle of the rubber pad need to be readjusted, and the workload is almost equivalent to rearranging
