Problems solved by technology

[0003] However, conventional plastic connections have various problems such as structural constraints, expensive special jigs, and a large number of processes. Currently, there are cases where it cannot be used or it needs to be used separately in each place.
Therefore, there is a problem that the production cost increases or the management becomes complicated.

Embodiment Construction

[0017] The present invention has the following features in terms of a method of connecting plate-shaped members. In short, in the present invention, the protrusions caused by plastic deformation protrude from the second plate-shaped member by pressing with the punch so as to fill the through-hole opened in the first plate-shaped member. Simultaneously, the material of the protruding part lost by the mold arranged to cover the surface of the through-hole of the first plate member flows in a direction away from the center of the through-hole, and the outer periphery of the protruding part engages with the inner wall of the through-hole, Only one process is used to connect the plate-like members. At this time, since the through hole is blocked by the filling of the protrusion, and the through hole is sealed by the mold, the protruding part of the protrusion cannot come out of the through hole on the side of the joined mold.

Abstract

The invention relates to a plate-shaped component connecting body, a plate-shaped component connecting method, and an image forming apparatus. In terms of the plate-shaped component connecting body, no boss will be formed on the joint face and connecting can be conducted. The plate-shaped component connecting body is connected to a first plate-shaped component (1) and to a second plate-shaped component (2), which overlap and form a communication hole (3). A component of the second plate-shaped component (2), corresponding to the communication hole (3) is pushed and pressed towards the direction of the communication hole, and thereby the component will be deformed, and a protruding part (7) can be formed. The protruding part (7) is filled in the communication hole (3) of the first plate-shaped component (1).

Description

technical field [0001] The present invention relates to a connected body of plate-shaped members, a method for connecting the plate-shaped members, and an image forming decoration using the connected body of the plate-shaped members. Background technique [0002] In stamped parts, sheet metal joining is an indispensable technology. Common joining methods include welding, screwing, etc. As low-cost joining techniques different from the above joining methods, various plastic joining methods such as flanging riveting and TOX riveting have been developed and known. . In addition, in recent years, steel plates of various materials are used, and the need for a plastic joining process has increased as a means of joining dissimilar materials. [0003] However, the conventional plastic connection has various problems such as structural constraints, the need for expensive dedicated jigs, and a large number of processes. Currently, there are cases where it cannot be used or it needs ...
