Description
Technical field
The present invention relates to accumulator manufacturing technology field, a kind of manufacture method for automobile storage battery terminal.
Background technology
The accumulator of automobile start in use for some time, engenders white on the connecting line of its positive and negative terminals
Acidic materials, time serious, pole root there will be scaling loss or corrode thus causes the phenomenon of leakage, industry is commonly referred to as climb acid or
Seepage.During production, it is that the terminal of finished product is placed on battery cap mould, is disposably injected and battery cap by injection machine
It is integrated, in cell assembling processes, after the terminal on battery cap welds with positive and negative terminals lead terminal post, forms accumulator
Both positive and negative polarity；This terminal passes through cold moudling, and this terminal has the terminal body being provided with endoporus, and described terminal body sets in bottom
There are the threaded portion for being tightly connected and the pole part being connected with described threaded portion by location division with described battery cap.This
In use there are the following problems for terminal: the bottom surface of terminal threaded portion is corroded with the faying face of battery container cover, electrolysis
Liquid along etching channels under air pressure inside or liquid fluctuating etc. act on, from internal storage battery threadingly portion and battery container cover it
Between gap outwards leak out, thus corrode pole part and electrical equipment, pollute environment, even affect the traveling peace of vehicle
Entirely.
Summary of the invention
The technical problem to be solved is to provide the manufacture method of a kind of accumulator cold end terminal, existing to solve
Cold end terminal easily occur pole part climb acid problem.
The present invention solves the technical scheme that technical problem used: the manufacture method of this accumulator cold end terminal, stores
Battery cold end terminal includes the terminal body being provided with endoporus, and described terminal body has threaded portion and by location division and described spiral shell
The pole part that stricture of vagina portion links, described threaded portion is provided with one annular groove in bottom surface, and the cross section of described annular groove is isosceles triangle, institute
The drift angle a stating isosceles triangle is 87 degree to 92 degree, and highly h is 1 millimeter to 2 millimeters；The thread of described threaded portion has root of the tooth
Portion and end head, the width b1 of the cross section of described end head is more than the width b2 of the cross section of described tooth root；
Comprise the following steps:
A, by gravity casting melted metal cast and there is described pole part, described threaded portion and be attached at described pole
The terminal body base of the described location division between portion and described threaded portion；
B, employing diel are by fine and close, smooth for the outer surface punching press of the described pole part of described terminal body base；
C, employing hobboing cutter are by the thread roll forming of the described threaded portion of described terminal body base；
D, employing hobboing cutter roll out described annular groove and i.e. complete the making of described accumulator cold end terminal in the bottom surface of described threaded portion.
Owing to have employed technique scheme, the present invention compared with prior art has the advantages that 1, thread
The width b1 of the cross section of end head, more than the width of the cross section of tooth root, can increase the grasping force of thread, make terminal body
Threaded portion terminal and cell jar be stamped good combination；Meanwhile, it is provided with one annular groove in the bottom surface of threaded portion, makes accumulator
Cold end terminal and battery container cover, when injection is merged, are full of filling plastic body in the annular groove of bottom surface, terminal body threaded portion, from
And cut off the passage of acid accumulator penetration, prevent electrolyte from outwards leaking out accumulator from the gap between threaded portion and battery container cover
Outside groove lid, thus protect pole part and the electrical equipment of terminal body, extend the life-span of battery, eliminate pollute environment because of
Element；2, by diel by fine and close, smooth for the outer surface punching press of the pole part of terminal body, accumulator cold end terminal can be improved
Service life.
