Sliding rail high-strength middleware structure and machining process thereof

Abstract

The invention relates to a sliding rail high-strength middleware structure and a machining process thereof. The sliding rail high-strength middleware structure comprises a middleware body, the two ends of the middleware body are bent and extend to form symmetrical side bodies, and grooves are formed in the side bodies; the middle of the middleware body is a protruding part, and the two ends of themiddleware body extend to form straight parts through inclined parts. The side body comprises a bent part I, a bent part II and a bent part III, and a hollow space is defined by the side body and thestraight part of the middleware body. After the section of the middleware is formed in a rolling mode, the groove in the middleware is formed through two steps of forward punching and lateral punching so as to meet the requirement for machining precision, and a sliding rail formed after the middle piece is matched with a large piece and a small piece can slide smoothly. The middleware is high instrength, and the deformation of the side body due to stress of the hollow structure is greatly reduced in the mode that the groove in the middleware is machined and formed in two steps, so that the machining precision of the middleware is improved, and smoothness of the sliding rail is guaranteed.

Description

technical field [0001] The invention relates to the technical field of slide rails, in particular to a high-strength middle part structure of slide rails and a processing technology thereof. Background technique [0002] A slide rail is a widely used device, usually used to connect two items that can move relative to each other. [0003] Most of the servers installed in the cabinet are equipped with slide rail devices, so that the server can be guided into the cabinet along the slide rails during installation and maintenance, thus putting forward load-bearing requirements for the slide rails. Under the premise of having a certain load-bearing performance, the slide rail needs to be able to slide smoothly under load-bearing conditions. [0004] In the prior art, the slide rail is composed of a large piece, a middle piece and a small piece. The middle piece connects the large piece outside and the small piece inside. Its structure and processing accuracy are very important fo...

Problems solved by technology

The existing middleware is a single-layer "C"-shaped structure. When the server is heavy, the slide rails are obviously limited in sliding
