Problems solved by technology
Although this method can reduce the tolerance, due to the large area of the side wall, more welding wire is required for repair welding, and it takes a long time to process (the processing area is the effective working surface of the side wall die), which increases Cost of production
Therefore, this adjustment method has a large workload, long mold debugging cycle and high cost.

Embodiment Construction
[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0021] Please refer to FIG. 5 , which is a flow chart of the method for adjusting the press-bending mold of the first embodiment. The press-bending molding die comprises a concave die and a punch, and the punch has convex rounded corners. The adjustment method comprises the following steps: (1) measuring the over-tolerance value produced by the molding of the mold; (2) according to the measured over-tolerance value Calculate the convex fillet of the punch as the radius of curvature required to correct the over-tolerance value; (3) adjust the convex fillet of the punch to reach the required radius o...

The invention discloses a method for adjusting a bending and molding mould. The mould comprises a concave mould and a convex mould; the convex mould is provided with a convex round angle; the bending and molding mould forms a pi-shaped beam or a U-shaped beam, and the adjusting method comprises: measuring super-difference value produced by mould molding, the difference being a difference of an actual value and a design value of a flange surface of the pi-shaped beam or a difference of an actual value and a design value of a sidewall edge height of the U-shaped beam, according to the measured super-difference value, calculating curvature radius needed for correcting the super-difference value by the convex round angle of the convex mould, and adjusting the convex round angle of the convex mould so as to reach the needed curvature radius. Through the adjustment of the convex round angle of the convex mould, the method for adjusting the bending and molding mould adjusts the super-difference of boundary dimensions / flange faces of various bending parts, thereby substantially reducing the workload of adjustment and reducing materials, adjustment time and cost.
Description
technical field [0001] The present invention relates to the technical field of mold forming, and in particular relates to a method for adjusting a bending forming mold for adjusting the tolerance generated during bending of the mold. Background technique [0002] At present, mold forming technology has matured day by day, and various mechanical parts can be manufactured through mold forming technology. For example, automobile beam parts are usually formed by molds, and there are two common types of automobile beam parts: beams without flange faces and beams with flange faces. A beam without a flange surface is a "U"-shaped beam 11 as shown in FIG. 1, and a beam with a flange surface is a "J"-shaped beam 12 as shown in FIG. The forming process scheme of the "U" beam 11 is: blanking, punching, and bending. The process plan of the "Ji" girder is (see Figure 3): Blanking and punching, primary bending, and secondary bending. The "U" shape is pressed into the "Ji" shape. When ...
