Lower die for machining drawer slide rail

Abstract

The invention relates to a lower die for machining a drawer slide rail. The lower die for machining the drawer slide rail comprises a first lower die body, a second lower die body, a third lower die body, a forth lower die body, a fifth lower die body, a sixth lower die body, a seventh lower die body, an eighth lower die body, a ninth lower die body and a tenth lower die body, wherein T-shaped grooves, first hole grooves, second hole grooves, guide wheel grooves and trapezoidal grooves are formed in the two edges of the first lower die body, a first bending groove, a second bending groove andfloating blocks are arranged on the second lower die body, drop-shaped groove extension parts are arranged on the third lower die body, annular grooves are formed in the rear end of the forth lower die body, the fifth lower die body is used for bending baffles with triangular teeth in trapezoidal holes, the sixth lower die body is used for forming a first floating plate with a 45-degree folded edge and a first blocking strip with an inclined surface, the seventh lower die body is used for forming a second floating plate with a 90-degree folded edge and a second blocking strip with a vertical surface, a third stop block used for turning over is arranged on the left side of the eighth lower die body, the front end of the third stop block gradually bulges upwards, and the outer side of the bulge forms an arc-shaped section. According to the lower die for machining the drawer slide rail, a punching machine is used for punching, and a steel strip is directly formed into a slide rail, so that time and electricity of the machining are saved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a lower mold for processing drawer slide rails, belonging to the technical field of sliding mechanisms. Background technique [0002] The traditional drawer slide rail usually includes a pair of slide rails respectively arranged on both sides of the bottom of the drawer. And sleeved in the vertical board, can slide along the vertical board. The mounting surface of the pull plate is tightly connected with the outer surface of the drawer, and the pull plate slides back and forth along the inner wall of the vertical plate to achieve the purpose of opening and closing the drawer. In the traditional processing method of drawer slide rails, the pull plates are usually processed in pairs. Cut out blanks with corresponding shapes and sizes on the raw materials, then put the blanks on the punching machine, punch out mounting holes on the mounting surface of the blanks according to the predetermined position, and then press and bend th...
