Embodiment Construction

[0016] 1. Press figure 1 As shown, the product is divided into three blocks A, B, and C on the drawing, and divided into three blocks 1, 1', 2, and 2' at the rounded corners.

[0017] 2. Computer graphics, draw the cardboard diagram according to the ratio of 1:1, and make the cardboard, the thickness of the cardboard is 1mm metal sheet.

[0018] 3. Press figure 1 A, B, and C dimensions on the above are respectively processed into actual products.

[0019] 4. Splice A, B, and C three physical products according to the pallet, and weld the welds 1, 1' and 2, 2'.

[0020] 5. Use a special abrasive tool - the electric grinding head is equipped with a file to rotate to remove the scars of the weld seam, and then use the sandpaper disc on the electric grinding head to polish the weld seam.

[0021] The invention is applicable to the processing of small batch, multi-variety and large-size thin plate parts.

Abstract

A technology for machining the shaped shielding case by plate-type copying method includes computer aided drawing by ratio of 1:1, preparing metallic plate, driving it into several blocks, assembling, welding, polishing welded seams, and cleaning. Its advantages are high productivity and quality and low cost.

Description

technical field [0001] The production of the special-shaped shielding cover involves mechanical processing technology, especially a clamp-type profiling processing method. Background technique [0002] Domestically, for small-batch and large-sized sheet-shaped metal materials such as aluminum plate parts, the traditional processing method is generally: make a mold → metal aluminum plate S = 2mm, put it on the mold and beat it with a wooden hammer → annealing treatment (250 ° C) → put it again Hit the mold twice with a wooden hammer → manually file off the scars of the hammer with a file → trim the mouth → polish → clean → transfer to the next process. This processing method has many processes and the mold manufacturing cost is high. [0003] Another production and processing method is to first design and manufacture a large low-melting point alloy mold → put the mold on a large-scale large-tonnage hydraulic press or hydraulic press, put S = 2mm aluminum plate for pressing a...
