Drawer slide rail and its manufacturing method

Abstract

Disclosed a slide rail of drawer and its manufacturing method comprises a standing plate, at least two drawplates and a cover of drawplate inside the standing plate and sliding along the standing plate. Wherein, a protruding ear for fixing is mounted on one drawplate, and mounting holes are arranged on said protruding ear while a concave meeting this protruding ear is arranged on another drawplate; each one drawplate at least has two groups of protruding ears and concaves which are mounted on the two ends of drawplate; the middle parts of two drawplates have a group of relative protruding ears and concaves; two drawplates are pressed and molded by the method of cover-cutting which comprises following steps: cutting the blank; incising the bland according to demanded shape and size on the raw material; pressing and bending to be molded as a conjoined unit with left and right drawplates; punching the mounting holes on the mounting surface of the blank according to the demand; separating the left and right drawplates according to the shapes of protruding ear and concave. Said inventive slide rail of drawer and its manufacturing method can save material and reduce the cost.

Description

technical field [0001] The invention relates to a drawer slide rail and a manufacturing method thereof. Background technique [0002] Traditional drawer slide rails usually include a pair of slide rails respectively arranged on both sides of the bottom of the drawer. Such as figure 1 As shown, the slide rail is composed of a vertical plate and a pull plate 1, wherein the vertical plate is installed on the inside of the table; the mounting surface of the pull plate 1 is provided with a mounting hole 2, which is socketed in the vertical plate and can slide along the vertical plate. The mounting surface of the pull plate 1 is tightly connected with the outer surface of the drawer, and the pull plate 1 slides back and forth along the inner wall of the vertical plate to achieve the purpose of opening and closing the drawer. [0003] In the traditional method of processing drawer slide rails, usually the pull plates 1 are processed in pairs. Cut out blanks with corresponding sh...

AI Technical Summary

Problems solved by technology

Since the installation surface and the drawer surface are tightly connected when the slide rail is installed, the force on the installation surface is not large during the back and forth sliding process of the slide rail. The traditional processing method of the slide rail obviously wastes the material on the non-fixed part of the installation surface.

Therefore, in the drawer slide rails produced in the prior art, the pull plate 1 has the defect that the width of the non-fixed part is relatively large. More materials are needed, and the production cost is higher

Therefore, the traditional drawer slides are no longer suitable for the existing manufacturing cost requirements
