Machining method of clamshell steel-wooden desk steel member

Abstract

The invention relates to a machining method of a clamshell steel-wooden desk steel member. The clamshell steel-wooden desk steel member comprises a front cabinet plate, a rear cabinet plate, a left cabinet plate, a right cabinet plate, an oblique cabinet plate and a bottom cabinet plate, which are respectively made of a steel plate. The machining method is characterized by comprising the following steps of (1) punching the left cabinet plate and the right cabinet plate; (2) punching a connection hole on the left cabinet plate and the right cabinet plate; (3) die pressing the left cabinet plate and the right cabinet plate; (4) flanging the left cabinet plate and the right cabinet plate; (5) cutting the front cabinet plate, the rear cabinet plate and the bottom cabinet plate; (6) punching a connection hole respectively on the front cabinet plate, the rear cabinet plate and the bottom cabinet plate; (7) bending a front cabinet plate sheet, a rear cabinet plate sheet and the a bottom cabinet plate sheet; (8) trimming and polishing; (9) primarily spraying; (10) secondarily spraying; and (11) assembling and modeling.

Description

technical field [0001] The invention relates to a student desk, in particular to a processing method for a steel component of a flip-type steel-wood student desk. Background technique [0002] A bookcase can be set under the desktop of the flip-top student desk. With the bookcase, some books, notebooks and student supplies can be put into the bookcase to solve the problem that too many books are stacked on the table and affect normal learning such as homework. Flip-top student desks are mainly composed of components such as desktop boards, bookcases and table legs. The bookcases include front cabinet boards, rear cabinet boards, left and right side cabinet boards and cabinet bottom boards. The boards are rotatably connected by hinges, etc., the tabletop board is a plank structure, and the bottoms of the cabinet boards on the left and right sides are fixedly connected with the table legs, and the table legs are made of materials such as steel or wood. However, the existing b...

AI Technical Summary

Problems solved by technology

However, the existing bookcases are made of wood or plastic boards or steel plates. Wooden bookcases have disadvantages such as troublesome processing, poor strength, easy damage, and tight resources; plastic bookcases are easy to deform, have many assembly connectors, and are not environmentally friendly. Disadvantages; so at present, most of the bookcases are made of steel plates, but the bookcases with steel plate components have the following shortcomings: First, the front and rear cabinet plates and the bottom plate are cut separately, and then welded to form, the material waste is large, and the processing Trouble, high cost, and not beautiful; second, the surface needs to be pretreated before painting, and the painted surface is easily damaged by collision or friction, and the exposed steel is easy to rust, which affects the service life; Pneumatic support rods need to be installed between the cabinets to make the opening light and avoid automatic downward closing. However, there will be hidden dangers between the pneumatic support rods and the edges of the left and right cabinet boards, and anti-guillotine flares need to be processed. The flaring with technology is processed by step-by-step extrusion, which is labor-intensive, time-consuming, equipment investment is large, and the quality is poor.
