As shown in fig. 5, fig. 5 is an effect schematic diagram of an arrangement position of the punching-wire spring knock pins, where a is a punching wire, b is the punching-wire spring knock pins, and a 'is an outer offset profile, and as can be seen in fig. 5, two punching-wire spring knock pins b are disposed on the outer offset profile a' of the punching wire a, and a path distance of the two punching-wire spring knock pins b on the outer offset profile a 'is half a circumference of the outer offset profile a'.
Specifically, in step S104, according to the position of the trim line, in combination with a preset trim line spring knock pin position calculation formula, an arrangement position of a trim line spring knock pin (a spring knock pin provided near the trim line) is generated, including:
inwards biasing the trimming line on a plane projection line of a two-dimensional plane perpendicular to the stamping direction to obtain an inner bias curve of the trimming line;
And according to the position of the trimming line on the automobile panel, combining a preset trimming line spring top pin position calculation formula, and generating the arrangement position of the trimming line spring top pin on the internal bias curve.

In order to solve the problem, the trimming line is divided into a plurality of discrete points before projection, a fitting algorithm is utilized to fit the discrete points into a two-dimensional curve, and then the two-dimensional curve is projected to a two-dimensional plane perpendicular to the stamping direction, so that a smooth plane projection line is obtained. The fitting process of the two-dimensional curve is the prior art, and the specific process can be realized by means of mathematical software and the like, and the detailed description thereof is omitted herein.
Specifically, in step S104, according to the position of the trim line on the automobile panel, in combination with a preset trim line spring top pin position calculation formula, an arrangement position of the trim line spring top pin is generated on the inner bias curve, including:

If yes, calculating to obtain the arrangement position of the trimming line spring top pin on the internal bias curve according to a preset trimming line spring top pin position calculation formula;
if not, the offset distance is adjusted to obtain an inner offset curve after the offset distance is adjusted until the position relation between the offset point of the inner offset curve after the offset distance is adjusted and the original point of the trimming line meets the preset relative position condition, and then the arrangement position of the trimming line spring ejector pins on the inner offset curve is calculated according to the preset trimming line spring ejector pin position calculation formula.
In step S104, the position of each trimming line on the automobile panel is obtained, the upper contour line, the lower contour line, the left contour line or the right contour line of the trimming line on the two-dimensional plane perpendicular to the stamping direction of the automobile panel is determined, and whether the point on the inner offset curve (the point is the offset point, and the arrangement position of the trimming line spring ejector pin needs to be set on the offset point) meets the preset relative position condition is determined according to the contour line (the upper contour line, the lower contour line, the left contour line or the right contour line) on which the trimming line is located. The preset relative position conditions are that the arrangement positions of the two spring ejector pins arranged near each trimming line are to be located on one side, close to the center of the automobile covering part, of the corresponding trimming line, so that the blanking type die of the automobile covering part is prevented from carrying out material carrying, structures such as scrap cutter inserts are avoided, and the stability of the blanking type die structure and the rationality of the spring ejector pin positions are guaranteed. When the contour line of the trimming line is an upper contour line (or a lower contour line), selecting any one original point from plane projection lines of the trimming line, acquiring an abscissa and an ordinate of the original point, selecting a bias point which is the same with the abscissa of any one point in an inner bias curve, acquiring the ordinate of the bias point, and if the ordinate of the bias point is smaller (or larger, when the contour line of the trimming line is the lower contour line and smaller, when the contour line of the trimming line is the upper contour line) than the ordinate of the original point, determining one side of the bias point on the inner bias curve, which is close to the center of the automobile panel, so as to determine that the position relationship between the original point of the trimming line and the bias point of the inner bias curve accords with a preset relative position condition; similarly, when the contour line of the trimming line is a left contour line (or a right contour line), the original point and the offset point with the same ordinate are obtained, if the abscissa of the offset point is larger (or smaller, when the contour line of the trimming line is a left contour line and larger, when the contour line of the trimming line is a right contour line and smaller), the abscissa of the original point is larger, one side of the offset point on the inner offset curve, which is close to the center of the automobile panel, is determined, so that the position relationship between the original point of the trimming line and the offset point of the inner offset curve is determined to accord with a preset relative position condition.
When the position relation between the original point of the trimming line and the offset point of the inner offset curve accords with a preset relative position condition, calculating the arrangement position of the trimming line spring top pin on the inner offset curve according to a trimming line spring top pin position calculation formula. When the arrangement position of the trimming line spring top pin is designed, a trimming line spring top pin position calculation formula is set to ensure that the arrangement position of the trimming line spring top pin meets the preset relative position condition. The trimming line spring top pin position calculation formula comprises a trimming line spring top pin position calculation formula in the abscissa direction and a trimming line spring top pin position calculation formula in the ordinate direction.
When the contour line of the trimming line is an upper contour line (or a lower contour line), calculating by adopting a trimming line spring top pin position calculation formula in the abscissa direction, wherein the trimming line spring top pin position calculation formula in the abscissa direction specifically comprises:

The value of n is generally set to 8, and can be adjusted according to actual needs.
Selecting the abscissa from the internal bias curve asAnd/>As the arrangement position of the trimming line spring ejector pin.
In summary, when the contour line of the trimming line is the upper contour line (or the lower contour line), the arrangement position of the trimming line spring pin is substantially a position on the inner offset curve, where the distance between the trimming line and the two ends of the inner offset curve in the abscissa direction is 1/n of the total length of the inner offset curve in the abscissa direction.
Similarly, when the contour line of the trimming line is a left contour line (or a right contour line), calculating by adopting a trimming line spring top pin position calculation formula in the ordinate direction, wherein the trimming line spring top pin position calculation formula in the ordinate direction specifically comprises:
；
；
wherein, Is the ordinate of the arrangement position of the spring pin of the first trimming line,/>Maximum value of ordinate in each position point of trimming line,/>Is the minimum value of the ordinate in each position point of the trimming line,/>And m is a preset positive integer greater than 1, which is the ordinate of the arrangement position of the second trimming line spring pin. The value of m is generally set to 8, and can be adjusted according to actual needs.
Selecting the ordinate from the inner bias curve asAnd/>As the arrangement position of the trimming line spring ejector pin.
In summary, when the contour line of the trimming line is the left contour line (or the right contour line), the arrangement position of the trimming line spring pin is substantially a position on the inner bias curve, in which the distance between the trimming line and the two ends of the inner bias curve in the ordinate direction is 1/m of the total length of the inner bias curve in the ordinate direction.
