Problems solved by technology

[0003] The traditional hollow needle processing method is that metal materials are made into finished products after punching, lathe, copper strip stamping and other processes. In the traditional process, metal materials such as copper are used for preliminary processing through punching machines to process metal materials into blank tires, After the position is adjusted, the copper strip is stamped to produce hollow needles after further processing on the lathe, and the speed is relatively slow. Finally, the hollow needles are surface treated to complete the production of hollow needles.

Embodiment 1

[0033] Embodiment 1 A kind of punching method of the cold pier forming of the hollow needle copper bar of rapid positioning forming, comprising:

[0034] 1. Select materials to remove impurities

[0035] Remove impurities after selecting a copper metal block of appropriate size

[0036] (1), manual wiping and scrubbing;

[0037] (2) Soak the copper metal material into the cleaning agent for heating and cleaning, soak the copper metal material into the trichlorethylene metal surface cleaning agent, use the principle of swelling to improve the solubility of organic pollutants such as oil, and completely remove the metal Surface organic pollutants, etc., the non-ionic surfactant contained in the cleaning agent can reduce the surface tension of the solution, and has a strong penetration ability, can penetrate between the metal surface and various pollutants, and hold up the pollutants , so that it is separated from the surface of the metal material to achieve the purpose of remo...

Abstract

The invention relates to the technical field of copper bar cold heading and stamping, in particular to a stamping method used for hollow pin copper bar cold heading and forming and capable of achieving quick positioning and forming. The stamping method comprises the steps of selecting a proper copper metal material, removing impurities on the surface of the copper metal material, placing the material on a stamping press for preliminary machining to form a copper metal strip, putting the copper metal strip on a lathe for machining and segmenting to form copper metal columns, performing surface treatment on the copper metal columns, and putting the copper metal columns into a cold heading mold of a cold heading machine for machining to form hollow pins. According to the stamping method used for hollow pin copper bar cold heading and forming and capable of achieving quick positioning and forming, a copper bar cold heading and forming method is adopted so as to increase the production quantity of the hollow pins per unit time and improve the production efficiency of the hollow pins.

Description

technical field [0001] The invention relates to the technical field of cold pier punching of copper rods, in particular to a punching method for cold pier forming of hollow needle copper rods for rapid positioning and forming. Background technique [0002] The hollow needle is a device used in various electrical appliances such as power plugs, power strips, etc. It plays the role of connecting circuits. It has the characteristics of fire prevention, flame retardancy, and conductivity. The quality of the hollow needle directly determines the service life of the electrical appliance; [0003] The traditional hollow needle processing method is that the metal material is made into a finished product after punching, lathe, copper strip stamping and other processes. In the traditional process, metal materials such as copper are used for preliminary processing through a punching machine to process the metal material into a blank tire. After the position of the hollow needle is adju...
