Description

Technical Field

[0001] This invention relates to the field of diesel engine processing, and more particularly to a processing apparatus for triangular tube plates of marine diesel engines and its method of use. Background Technology

[0002] After the triangular tube plates for marine diesel engines are formed by blanking or cold bending, their bevels need to be processed to meet the requirements for bevel angle and surface roughness, thereby enabling single-sided welding and double-sided forming. Screw holes also need to be machined on them for part installation. Triangular tube plates are typically formed by blanking and flattening, or by blanking, flattening, and cold bending. There are many types of bevels for triangular tube plates, with bevel angles generally ranging from 20° to 70°, showing considerable variation. The surface of the triangular tube plates is relatively narrow, with a width generally between 250-480mm, a length between 3000-5000mm, and a thickness between 18-32mm. The inherent characteristics of triangular tube plates mean that they experience significant vibration during processing. A common approach is to create specialized tooling, with each type of triangular tube plate having a tooling of a specific angle to meet the clamping and bevel angle requirements during processing.

[0003] The angle dimensions of triangular tube plates for marine diesel engines vary across different models. Current practices involve creating custom fixtures for each model, resulting in numerous fixtures, wasted labor, raw materials, and energy, thus increasing manufacturing costs and extending production cycles. Alternatively, boring machines or milling machines with attachment heads can be used to process the triangular tube plates. Even with boring machines, at least two clamping operations are required to complete the beveling of three different angle dimensions on two sides of the same triangular tube plate. The equipment unit price is higher than that of ordinary boring and milling machines, increasing manufacturing costs. Furthermore, the variety of triangular tube plate types creates significant clamping challenges, requiring the use of fixtures with the corresponding angles for each model during clamping and adjustment. Frequent fixture changes and clamping adjustments not only lead to low work efficiency but also increase the risk of inconsistent workpiece quality, further wasting resources.

[0004] Therefore, it is necessary to provide a new marine diesel engine triangular tube plate processing device and its usage method to solve the above-mentioned technical problems. Summary of the Invention
