Precision progressive die for condenser support

Abstract

The invention relates to a precision progressive die for a condenser support. The precision progressive die for the condenser support comprises an upper die assembly, a lower die assembly, an unloading plate, an unloading plate bolster and a mistaken feeding detecting device, wherein the upper die assembly is successively provided with corresponding convex dies and concave dies in the feeding direction; and the lower die assembly is successively provided with concave dies and convex dies which are matched with the upper die assembly in the feeding direction. By the precision progressive die, the condenser support can be manufactured by continuous punch forming. Compared with a single operation die for production, the precision progressive die for the condenser support can guarantee the quality of the product, and furthermore, the number of required dies can be reduced. The condenser support is reasonable in layout design, and the die is simple in structure and convenient to operate. After being tried for a period of time, the precision progressive die for the condenser support has good use effect, and meets requirements of large-scale, efficient and high-quality production of parts.

Description

Technical field [0001] The invention relates to a mold, in particular to a precision progressive mold for a condenser bracket. Background technique [0002] Condenser bracket (such as Figure 1-Figure 3 As shown), the material is SAPH440, the material thickness t=4mm, the tensile strength of the material is ≥440MPa, and the elongation is ≥30%. It is a common high-strength hot-rolled steel sheet for automobiles. From Figure 1-Figure 2 It can be seen that the condenser bracket needs multiple bending and forming in two directions, and it also has processes such as beading, indentation, punching and punching. If a single-process mold is used for production, not only multiple molds need to be manufactured, but also there are deficiencies in the shape and size of the unfolded material, secondary positioning errors, and unstable bending springback. The quality of the parts cannot be guaranteed, so it is suitable to use fine blanking progressive mold production. Summary of the invention...

Problems solved by technology

If a single-process mold is used for production, it is not only necessary to manufacture multiple molds, but also there are deficiencies in the shape and size errors of the unfolded material, secondary positioning errors, and unstable bending and springback, and the quality of the parts cannot be guaranteed. Therefore, it is suitable to use fine-blanking progressive die production.
