Description

Reinforced chassis structure

Technical Field

Background

Currently, in industry practice, there are two most common non-detachable reinforced chassis structural forms, the first: the welding type and the structure type are most common, and other 5 cover plates except the upper cover plate are welded into a whole, so that the design target of undetachable is achieved. The device has the advantages of strong universality and high structural strength; second kind: paint covering. The structure is similar to a traditional spliced reinforced chassis, other 5 cover plates except the upper cover plate are connected into a whole in a threaded manner, and exposed screw holes are smoothed and covered in the subsequent surface painting process, so that the appearance of undetachable is visually realized;

disadvantages of welded construction:

and the problem of material deformation caused by welding. In order to overcome the defect of deformation after welding, the material processing allowance is reserved before welding, a welding clamp is used in the welding process, and the appearance of the welded secondary processing reaches the required product size. These steps, above, bring about an increase in process steps and costs.

Drawbacks of paint covered constructions:

(1) Not physically and conceptually undetachable, the screws can be exposed after the paint layer is detached, and the undetachable design is broken;

(2) The cover plate material is different from the screw material, and the thermal expansion coefficient is also different, so that under the damp and hot working condition, the paint at the screw has a certain probability of bulge and cracking, and the aesthetic degree of the product is influenced.
