Description
Technical Field
The utility model belongs to the technical field of the punching press of battery box hat, a towards cup mould is related to, concretely relates to box hat towards cup compound die for basicity zinc-manganese cell box hat towards cup.
Background
The alkaline battery steel shell is formed by stretching a thin steel strip through multiple stations, and generally, blanking and primary stretching are completed through a compound die at a first station, namely cup punching for short. In fact, the blanking and stretching actions are completed, and four main actions are opened in an expanding way: blanking, pressing, stretching and stripping. At present, the domestic punch press industry is generally a single-slide block universal punch press, under general conditions, the four actions are realized and continuous punching is realized by installing a compound die on the single-slide block universal punch press, the stability and the reliability are not high, and the current more typical compound die structure is shown in figures 5 and 6.
The existing cup punching compound die mainly comprises two parts, wherein an upper die part 10 is fixed on the bottom surface of a sliding block of a punch press through an upper die fixing plate 1.1, and a lower die part 20 is fixed on a working bedplate of the punch press through a lower die fixing plate 2.3. When the slide block of the punch press descends, the blanking upper knife edge 1.2 firstly contacts the strip and the stripper plate 2.2 and pushes the stripper plate 2.2 to interact with the lower die 2.1 to finish blanking, then the material pressing ring 1.4 contacts the lower die 2.1 to execute material pressing action, the slide block continues to descend, and the drawing punch 1.3 interacts with the lower die 2.1 to finish drawing, as shown in fig. 6. Wherein: when the slide block moves downwards or upwards, the material pressing ring 1.4 performs material pressing action and resetting under the action of the material pressing spring 1.7 through the push rod 1.5 and the top plate 1.6; a return spring (not shown) is also arranged between the stripper plate 2.2 and the lower die fixing plate 2.3.

This towards cup compound die's last mould part 1 fixes in punch press slider bottom surface through upper die fixing plate 1.1, moves along with the slider, and the stroke is equal basically, and the reliability has inherent not enough, specifically has:
a. because the movement stroke of the blanking upper knife edge 1.2 and the stretching punch 1.3 is basically equal, the lower die 2.1 can not be provided with a stripping device of the cup shell, the formed cup shell sleeved on the stretching punch 1.3 can only be stripped by depending on the bayonet at the A part of the lower die 2.1, and the cup shell is required to be formed: the upper opening needs to be properly turned outwards so as to have a hanging space for stripping; in addition, the bayonet at the A position of the lower die 2.1 needs to be properly processed, is properly rounded and is excessively chamfered, so that the edge of the cup shell can scrape threads when the materials are removed, and the materials cannot be removed when the rounding is excessively large. Even if the 2 points are properly processed, the failure rate and the maintenance rate are high.
b. The relative movement distance of the material pressing ring 1.4 is larger, and under the action of the material pressing spring 1.7, the difference between the initial material pressing force and the final material pressing force is larger, so that the rim of the cup shell is pressed and stepped frequently, and the subsequent multi-station further gradual stretching is not facilitated.
Aiming at the defects, the prior structure needs to be further optimally designed, so that the four actions of blanking, pressing, stretching and stripping can be stably and reliably realized on a single-slider universal punching machine, and continuous punching is realized, and the aim of improving the production efficiency is fulfilled.
