Benefits of technology
The invention provides a way to make stronger and cheaper connections between two parts, by using a special tool to form a curved shape on the surface of one part and attach it to another part using rivets. This method simplifies the manufacturing process and reduces manufacturing costs.
Problems solved by technology
However, the aforesaid steps of forming the embossed structure and pressing the embossed structure back will form an indentation on the surface of the sheet metal member, such that the appearance of the product will be affected.
Furthermore, if the sheet metal member needs to be reinforced by more processes, the mold design gets more complicated, such that the mold cost will increase.
Still further, the more the working stations are, the higher the manpower and machine cost is.
Consequently, the sheet metal member must be discarded, such that the material is wasted.

Abstract
A curve forming and riveting method includes steps of providing a sheet metal member, a riveting member and a forming mold, wherein the forming mold has a curve forming portion; attaching the sheet metal member to the curve forming portion; assembling the riveting member to the sheet metal member; and riveting the riveting member and the sheet metal member together by the curve forming portion and forming a curve contour on the sheet metal member corresponding to the curve forming portion.
Description
BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The invention relates to a curve forming and riveting method and, more particularly, to a curve forming and riveting method capable of increasing strength and decreasing manufacturing cost.2. Description of the Prior Art[0002]So far a casing of various electronic devices is made of a sheet metal member. In general, since the sheet metal member is thin, the prior art forms an embossed structure on the sheet metal member first and then presses the embossed structure back, so as to increase strength of the sheet metal member. Furthermore, for different appearance designs, the prior art uses a curve forming mold to form a curve contour on the sheet metal member after reinforcing the sheet metal member. Then, the prior art measures the curve contour to determine whether the curve contour conforms to a standard value. If the curve contour does not conform to the standard value, the prior art uses a new sheet metal member to repeat ...
