Method for producing three-section type sliding track

Abstract

A method for producing a three-section slide rail comprises the following steps: stamping an outer rail; rolling a middle rail body which can slide in the outer rail; rolling an inner rail body which can slide in the middle rail; stamping a limiting structure for limiting slide routes of the slide rail on the middle rail body; and stamping a limiting structure for limiting slide routes of the slide rail on the inner rail body. The method for producing the three-section slide rail combines a stamping and rolling processing technique to produce the slide rail with the advantages of simple and practical structure and low production cost.

Description

technical field [0001] The invention relates to a method for manufacturing a slide rail, in particular to a method for manufacturing a three-section slide rail combined with different processing techniques. Background technique [0002] Common three-section slide rails include inner rails, middle rails and outer rails. The inner rails are combined with the server chassis, and the outer rails are fixed on the server cabinets to carry the servers. The inner and middle rails can slide back and forth relative to the outer rails along the axis of the outer rails. , in order to prevent the chassis from being directly pulled out of the outer rail, the inner rail, middle rail and outer rail are all provided with structures that cooperate with each other to limit the extension or retraction stroke of the slide rail, such as protrusions, flaps, openings, etc. [0003] There are currently two manufacturing processes for slide rails, one is the rolling process (also known as rolling), a...

Problems solved by technology

The disadvantage of the rolling process is that it is impossible to produce features such as large bends, protrusions, or local deformations. Therefore, the rolling process can only manufacture the slide rails that require large bends into two separate components, and then use the fixed Parts fix the discrete components together. This kind of slide rail made by rolling process has many parts and complex structure.

The advantage of the stamping process is that it can stamp out complex structures such as large bends and bulges that are formed at one time, but the stamping process is low in benefit and high in cost

At present, ball-type three-section slide rails are usually made by rolling processing technology, and friction-type three-section slide rails are usually made by stamping processing technology, both of which have certain limitations.
