Problems solved by technology

The existing production of battery connection copper sheet is to directly stamp the copper sheet, and then carry out surface treatment and heat treatment. Because the copper sheet is brittle, it is easy to be stamped and deviated during the stamping and forming process, resulting in defective products, which not only wastes copper material , also delaying the normal production working hours

Embodiment 1

[0019] A production process for connecting copper sheets for automobile batteries, comprising the following steps:

[0020] (1) Pretreatment: soak the copper sheet in 80°C lime water for 5 hours, and then use 60°C methanol solution containing 30% ether to soak for 2 hours;

[0021] (2) drying treatment: send the pretreated copper sheet into the drying chamber for drying;

[0022] (3) Stamping forming: the copper sheet is punched by a punching machine;

[0023] (4) Surface treatment: polish the stamped copper sheet with sandpaper, and then put it into a salt water pool for 2 hours in a salt bath, and maintain the temperature of the salt water at 60-80°C;

[0024] (5) Heat treatment: Send the copper sheet to the heating furnace for heating treatment, and the furnace temperature is maintained at 400-500 °C;

[0025] (6) Cooling: the heat-treated copper sheet is forced to be cooled by a fan;

[0026] (7) Inspection: The quality inspector inspects that the appearance and size of...

Abstract

The invention discloses a production process for a connecting copper sheet of an automobile battery. The production process comprises the following steps of pretreatment, drying treatment, punch forming, surface treatment, heat treatment, cooling, checking, and packaging. According to the production process, the copper sheet is soaked by utilizing lime water and a methanol solution containing 30% of ethyl ether before being punched, so that the treatment effect is good, the hardness of the copper sheet is enhanced, and the copper sheet is easy to punch and machine; and the copper sheet is quenched before being punched, so that the machinability of the copper sheet can be further improved.

Description

technical field [0001] The invention relates to the technical field of production of battery connection copper sheets, in particular to a production process of automobile battery connection copper sheets. Background technique [0002] Copper is widely used as a conductive medium because of its good electrical conductivity. Car batteries use copper sheets as the conductive connection material for the positive and negative electrodes. The existing production of battery connection copper sheet is to directly stamp the copper sheet, and then carry out surface treatment and heat treatment. Because the copper sheet is brittle, it is easy to be stamped and deviated during the stamping and forming process, resulting in defective products, which not only wastes copper material , Also delay the normal production hours. Contents of the invention [0003] The purpose of the present invention is to provide a production process for connecting copper sheets for automobile batteries. Be...
