Abstract
The utility model discloses a high-precision blanking die structure of a steel battery shell and is applied to the field of production technology of thin-walled steel battery shell. The die structure comprises an upper die frame plate and a punch workbench plate, wherein a blanking upper die plate and a stretching upper die fixing plate are mounted below the upper die frame plate; a blanking upper die is mounted on the blanking upper die plate; a plurality of parallel spaced stretching puncher pins are arranged on the stretching upper die fixing plate; a blanking lower die plate and stretching female dies, which correspond to blanking upper die plate and the stretching puncher pins, are arranged on the punch workbench plate; a blanking lower die is mounted on the blanking lower die plate; a guide mechanism formed by a die frame guide sleeve and a die frame guide post is arranged between the upper die frame plate and the punch workbench plate; and an independent positioning and guiding component is arranged between the blanking upper die plate and the blanking lower die plate. The die structure not only can improve the fitting accuracy of the upper die and the lower die, but also can prolong the service life of the die, is convenient to assemble and disassemble, shortens maintenance time and improves production efficiency.
Description
Technical field
The utility model relates to a kind of thin wall battery shell production mould, especially relates to a kind of battery steel shell high accuracy blanking die structure.
Background technology
At present, the thin wall battery box hat generally all adopts the progressive die punching.see also shown in Figure 1, Fig. 1 is the schematic diagram of traditional battery steel shell blanking die structure, it comprises patrix frame plate 10 and the corresponding work bench of punch press plate 11 that is arranged at patrix frame plate 10 belows, the below of described patrix frame plate 10 is equipped with blanking upper die plate 12 and stretching upper mould fixed plate 13, on described blanking upper die plate 12, blanking upper die is installed, be disposed with the draw punch 14 that a plurality of parallel interval are arranged on described stretching upper mould fixed plate 13, corresponding blanking upper die plate 12 on described work bench of punch press plate 11, draw punch 14 is provided with blanking lower bolster 15 and stretching die 16, the blanking counterdie is installed on described blanking lower bolster 15, the guiding mechanism that is comprised of mould bases guide pin bushing 17 and mould bases guide pillar 18 is installed between described patrix frame plate 10 and work bench of punch press plate 11.The characteristics of this mould structure are that whole 7～10 road patrixes: comprise that blanking upper die and draw punch 14 all are integrated on a patrix frame plate, the part of the lower die is that single track independently is fastened on working plate.A whole set of mould often only adopts cover (two a pairs) mould bases guide pin bushing 17 and mould bases guide pillar 18 to guarantee the position degree of upper and lower mould, namely between whole patrix frame plate 10 and following work bench of punch press plate 11, shares a cover guide pillar guide pin bushing.The mould of this structure reaches result of use theoretically, is also feasible, and popular in the industry for many years.
But also there is certain defective.Because this mould structure is as stretched portion, all draw punchs 14 all are arranged on a monoblock stretching upper mould fixed plate 13, draw punch 14 no doubt can not produce displacement each other, yet blanking die is to be fastened on separately on patrix frame plate 10, be in operation, do not produce displacement with patrix frame plate 10 unavoidably.Whole patrix frame plate 10 and stretching upper mould fixed plate 13 relies on the guide pillar guide pin bushings, guaranteed and the coordinating of counterdie, and but differing guarantees the position degree (moreover the blanking counterdie is also independently to be fastened on working plate) of blanking die up and down surely.Like this, deviation is large sometimes, and the tipping phenomenon will appear in blanking die.In addition, blanking die is with respect to stretching die, and the number of times of maintenance is much more (because wanting frequent reconditioning cutting edge), and because location not guarantees, each dismounting is adjustment upper and lower mould position repeatedly all, so relatively more bothersome trouble.
The utility model content
The purpose of this utility model is to provide a kind of battery steel shell high accuracy blanking die structure, it has the advantages that the upper and lower mould quality of fit is high, dismounting is convenient and die life is long, to solve the problem that in prior art, battery steel shell high accuracy blanking die structure exists.
The purpose of this utility model is to be achieved through the following technical solutions:
a kind of battery steel shell high accuracy blanking die structure, it comprises patrix frame plate and the corresponding work bench of punch press plate that is arranged at patrix frame plate below, the below of described patrix frame plate is equipped with blanking upper die plate and stretching upper mould fixed plate, on described blanking upper die plate, blanking upper die is installed, be provided with the draw punch that a plurality of parallel interval are arranged on described stretching upper mould fixed plate, corresponding blanking upper die plate on described work bench of punch press plate, draw punch is provided with blanking lower bolster and stretching die, the blanking counterdie is installed on described blanking lower bolster, the guiding mechanism that is comprised of mould bases guide pin bushing and mould bases guide pillar is installed between described patrix frame plate and work bench of punch press plate, wherein, on described blanking, be provided with independently positioning and guiding assembly between lower bolster.
Especially, described positioning and guiding assembly comprises the blanking die guide pin bushing that is installed on the blanking upper die plate and the blanking die guide pillar that is installed on the blanking lower bolster.
Especially, described blanking die guide pin bushing and blanking die guide pillar are set to two pairs.
Especially, be both direction arrangement in length and breadth between described blanking die guide pillars and bushes and mould bases guide pillars and bushes.
The beneficial effects of the utility model are that described battery steel shell high accuracy blanking die structure has compared with prior art added cover (two a pairs) guide pillar guide pin bushing again on the bolster of blanking die, made it independently navigation system.In addition, blanking die guide pillar guide pin bushing becomes both direction arrangement in length and breadth now with mould bases guide pillar guide pin bushing, has more improved the quality of fit of upper and lower mould.Like this, not only avoid mould tipping phenomenon, extended die life; And when the dismounting mould, as long as installation in position, repeatedly adjustment upper and lower mould position, simplified the installation formality, shortened maintenance time, improved production efficiency.
