Problems solved by technology

[0005] When using the stretch forming process to process the slat slide rail sleeve, the requirements for the processing material and the stretching process are relatively high. The common stretching process Only emphasizing the process, not the material, or only emphasizing the material without talking about the drawing processing process. Since different materials use different processes, avoiding the material itself to talk about the process will reduce the strength and life of the parts after stretching. The slat slide sleeves that come out are not very effective in use, and the processing efficiency is not high

Abstract

The invention discloses a deep stretch forming production process of a slat slide rail sleeve, and relates to the technical field of stretch forming. The deep stretch forming production process comprises the following steps that S1, raw materials are proportioned, specifically, the following components are proportioned in percentage by mass: 5.6-6.3% of Mg, 0.4-1.0% of Mn, 0.09-0.13% of Cr, 0.15-0.2% of Ti and the balance of Al; S2, metal smelting is conducted, specifically, alloy powder is molten into an aluminum alloy cast ingot; S3, quenching is conducted, specifically, the aluminum alloy cast ingot is quenched; S4, hot rolling is conducted, specifically, the aluminum alloy cast ingot is hot-rolled into an aluminum alloy plate; S5, rolling is conducted, specifically, the aluminum alloy plate is rolled; and S6, stretching is conducted, specifically, an aluminum alloy cylinder is further stamped and stretched. The aluminum alloy cast ingot is firstly hot-rolled into the aluminum alloy plate through hot rolling, then rolling is conducted, stamping and stretching are conducted after rolling, the wall thickness of the aluminum alloy plate is gradually reduced, and the finished aluminum alloy cylinder obtained through machining is good in forming, few in surface defect and high in machining efficiency.

Description

technical field [0001] The invention relates to the technical field of stretch forming, in particular to a production process of deep stretch forming of a slat slide rail sleeve. Background technique [0002] Stretch forming is a technology that improves the unloading structure of the forming die. Its advantages can automatically unload the parts under the action of the spring, improve the unloading efficiency, and do not damage the parts. The mold structure is simple, reducing manufacturing costs and shortening the manufacturing process. cycle, easy to use and maintain. [0003] Under the action of load, the sheet metal is constrained by the shape of the cavity, and its boundary changes continuously. During the entire deformation process, some boundary parts of the material may gradually come into contact with the mold and become constrained boundaries, and at the same time, some material surfaces that are already constrained may lose contact with the mold surface and beco...
