Problems solved by technology

[0003] 1. The aluminum ingot blank is heated and formed by the mold. This processing method has many additional equipment for the mold, and the manufacturing cost is high, which cannot adapt to market competition;
[0004] 2. CNC processing of aluminum ingot blanks is difficult to process, low in production capacity, high in unit price, and unable to adapt to market competition
In order to realize the design of the bottom cover of the charging treasure shell, for example, the Chinese patent "CN109092977A" - a punching device for the charging treasure shell, specifically discloses the use of die punching instead of milling processing, which solves the problem of difficult processing due to the CNC machining of aluminum ingot blanks. The production capacity is low, the unit price of the product is high, and it cannot adapt to the market competition. However, this processing method still has the problems of many additional mold equipment, high manufacturing costs, and cannot adapt to the market competition.

specific Embodiment 1

[0027] Such as figure 1 , figure 2 As shown, specific embodiment 1, a method for cold forging and stretching of a charging treasure shell, comprising the following steps:

[0028] S1: aluminum ingot rough blank forming: aluminum ingot rough blank is formed by aluminum extrusion;

[0029] S2: Aluminum ingot blank forming: use a cutting machine to cut the rough aluminum ingot in step S1 into columnar aluminum ingot blanks with a height of 32.5mm, a length of 74.8mm and a width of 21.3mm. The rough ingot is cut into aluminum ingot blank;

[0030] S3: Cleaning: Wash the drum for 20 minutes and rinse with clean water;

[0031] S4: heat treatment: conduct softening annealing heat treatment on the surface of the aluminum ingot blank, that is, dry it in a high-temperature electric furnace at 425°C and keep it warm for 5.5 hours, so that the state of the material is O state, that is, the hardness of the raw material is softened to the range of HV13-20 degrees.

[0032] S5: Stirrin...

Abstract

The charger pal shell is formed through aluminum ingot rough blank forming, aluminum ingot blank forming, cleaning, heat treatment, stirring spraying and punch forming, the plasticity of solid metal is improved through the forming method and the die to reach a relatively high stretching height, and the side wall of the charger pal shell is evenly formed through one-time stretching forming.

Description

technical field [0001] The invention relates to the technical field of intelligent charging devices, in particular to a cold forging stretching method and a mold for a charging treasure shell. Background technique [0002] Charging treasure is also called mobile power supply, travel charger and so on. A portable charger integrating power supply and charging functions, which can charge mobile phones, tablet computers and other digital devices anytime and anywhere. The shell is generally aluminum shell, which has the characteristics of lightness, durability, and good hand feeling. The aluminum casing is generally formed by extruding an aluminum rod in a high temperature state through an extrusion machine through a die. However, aluminum profile extrusion dies can only achieve straight-through product designs. Common shell processing usually includes the following steps: DDG (double-end high-speed grinding), CNC roughing, T treatment, PMH injection molding, CNC finishing, po...
