Embodiment Construction

[0030] FIG. 1 is a perspective view showing an example of a sheet metal product according to an embodiment of the present invention.

[0031] The overall sheet metal product denoted by reference numeral 1 is, for example, a cover assembly equipped at the front of the machine tool.

[0032] The cover unit 1 is composed of a cover sheet 10 formed by molding a metal plate, and corner members 230 , 410 , which will be described later, mainly mounted around the cover sheet 10 .

[0033] The cover sheet 10 is provided with an opening 20 and the like, and a window for observing the machining part of the machine tool from the outside of the cover is attached thereto.

[0034] FIG. 2 is an exploded view of main components constituting the cover assembly 1 .

[0035] Fig. 2 is a view of the cover sheet 10 viewed from the front, but the upper edge 10a, the lower edge 10b, the left edge 10c, and the right edge 10d of the cover sheet 10 are respectively fixed with reinforcing parts to ens...

Abstract

To provide a method of manufacturing a large-size sheet metal product with a three-dimensional shape such as a cover for a machine tool without a welding step, and also to provide its product. A cover unit 1 for a machine tool is manufactured by fixing edge members 110, 120, 130, 210, 220, 230 on the periphery of a cover sheet 10 by a fixing tool such as a bolt or a nut. In the cover sheet 10 or the respective edge members, the flat development based on data of a three-dimensional solid model of the cover unit 1 is nested on the sheet metal material on a laser beam machine, and laser beam machining is carried out. In the laser beam machining, the respective members are marked with information on bending lines, bending angles, or the like necessary for post processes. The members which have been precisely laser beam machined are subjected to necessary bending works, and assembled by the fixing tool, so as to obtain the large-size sheet metal product with the three-dimensional shape without the welding step.

Description

technical field [0001] The present invention relates to a sheet metal product having a three-dimensional shape, such as a machine tool cover, and a manufacturing method thereof. Background technique [0002] Generally, when manufacturing a three-dimensional sheet metal product such as a machine tool cover, the sheet metal parts constituting the cover are planarly developed from the cover design drawing. Use CAM technology to nest (nesting) the planar unfolded component group on a sheet metal of a certain size. And, the nested component group is cut with a laser processing machine. Bending the parts to be bent in the cut processed parts with a bending machine. In this way, a group of parts forming the cover is produced, and the final cover is produced by assembling the parts with each other. [0003] In such a manufacturing process, a component group forming the cover is produced, and the components are assembled together, and the components are generally assembled by a we...
