Embodiment Construction

[0050] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0051] Space envelope forming under straight line trajectory can be used to form the upper surface features of various workpieces, such as pits and bosses on the upper surface of workpieces. Such as figure 1 As shown, (a) is the workpiece with concave features on the surface, (b) is the workpiece with linear convex features on the surface, and (c) is the workpiece with curved convex features on the surface. In addition, workpieces with complex features on the surface such as racks and mobile phone cases can be quickly enveloped by the space envelope forming method under the linear trajectory.

[0052] In order to have a better and clear understanding of the technical features, purpose and effects of the present inventi...

Abstract

The invention relates to an accurate design method for a space envelope forming envelope die under a linear track. The accurate design method comprises the following steps: S1, establishing a rectangular coordinate system; S2, determining an envelope axis; in the xoy plane, selecting a straight line passing through a point O as an envelope axis, wherein the envelope axis cannot penetrate through the upper surface of the component, and the included angle between the envelope axis and the x axis is theta; S3, enabling the envelope axis determined in the step S2 to serve as a boundary, dividing the upper surface of the component into a left area and a right area, wherein the coordinate of any point on the upper surface of the component is (x, y, z); and S4, selecting any point M (Mx, My, Mz)of the right area, mapping the point M upwards and anticlockwise around the envelope axis, to ensure that the distances from the point M and the mapping point to the envelope axis are equal, so that the mapping point M '(M'x, M'y, M'z) is any point on the right area of an envelope mold. the enveloping mold needed in the linear track enveloping forming process of the workpiece can be obtained, andthe design precision of the enveloping die is improved.

Description

technical field [0001] The invention relates to the technical field of space envelope forming, in particular to an accurate design method of an envelope die for space envelope forming under a straight line trajectory. Background technique [0002] Space envelope forming refers to the plastic forming method in which the complex spatial motion of the envelope mold is enveloped into a complex shape of the component during the relative movement of the envelope mold and the component. The space envelope forming technology belongs to the new technology of continuous local plastic forming. The complex features of the components can be directly formed through the envelope motion of the envelope mold. The forming force is small, the material utilization rate is high, the forming accuracy is good, and a better metal flow line can be obtained. , so that the performance of the component is guaranteed, so as to meet the requirements of high-performance and high-efficiency forming and man...
