Suspension supporting base multi-station progressive die

Abstract

The invention relates to a suspension supporting base multi-station progressive die which comprises an upper die assembly, a lower die assembly, an unloading plate, an unloading plate base plate and a mis-feeding detection device. The upper die assembly is sequentially provided with a corresponding male die in the feeding direction, the lower die assembly is sequentially provided with a female die embedding sleeve matched with the male die of the upper die assembly, corresponding positions on the unloading plate and on the unloading plate base plate are provided with a through hole capable of penetrating through the male die of the upper die assembly, the unloading plate is disposed on the unloading plate base plate, and the unloading plate base plate is arranged on the upper die assembly through an unloading spring. By means of the progressive die, suspension supporting bases are produced in a continuous drawing progressive die mode. The mechanism is compact in structure, high in guide precision, stable in unloading and precise in pitch fixing, and feeding and discharging are convenient to achieve. A quick replacement structure is adopted to a punching male die, and maintenance and replacement time of the die is effectively shortened. After being tried, the mechanism is good in use effect and can meet requirements for high efficiency and high precision of stamping production.

Description

technical field [0001] The invention relates to a mold, in particular to a multi-station progressive mold for a suspension support seat. Background technique [0002] The material of the suspension support seat is DC54D+AZ, and the material thickness t is 0.6mm. DC54D+AZ is a hot-dip galvanized sheet, which is produced by continuous hot-dip galvanizing process with hot-rolled steel strip or cold-rolled steel strip as the substrate. Its yield strength is 120-220 MPa; It is 260-350 MPa; the elongation after breaking is ≥36%. It has the advantages of good deep drawing performance, corrosion resistance, good surface quality, economical and practical, etc. It is mainly used for deep drawing in the fields of construction, electrical instruments, household appliances, automobiles, etc. processing. [0003] The suspension support seat belongs to auto parts, which is a stepped box-shaped deep-drawing part with an overall size of 162mm×169mm×19mm, which requires high surface quality...

Problems solved by technology

[0004] The production process of the original suspension support seat is to use multiple sets of single-process moulds. Not only does it need to manufacture multiple molds, but the machine tool occupancy rate is high, and there are errors in the shape and size of the unfolded material and secondary positioning errors, resulting in unstable product quality and poor part quality. Can't guarantee

Moreover, the labor intensity of workers is high and the production cost is high, which is not conducive to mass production
