This is an introduction to a case study of the fabrication of a canning processing frame made by Mitsuya.
This product is a frame for equipment used in machine tools and industrial machinery. It is welded by combining three types of square pipes and thick plates. Typically, such frame structures consist of an upper square pipe frame that serves as the base for the thick plate on top and a lower square pipe frame on the bottom, which are similar in design. After combining the four square pipes, additional square pipes are inserted between them to form the frame shape. However, this results in the side surfaces of the upper and lower frames having the ends of the square pipes exposed, necessitating the use of end plates to cover these ends, which increases welding labor and consequently raises costs. Therefore, at Mitsuya, we first assemble the square pipe frame for the side sections and insert intermediate square pipes to shape the frame. This allows the exposed ends of the square pipes on the top and bottom to be filled with thick plates, enabling production without increasing the number of components. Since large tapping operations were required on the thick plate surface extending to the square pipes, we ensure high-precision tapping by requesting a cooperating company with a five-sided machining machine to handle the tapping, including for the side and bottom surfaces.
Inquire About This Product
basic information
The weld bead connecting the thick plate and the square pipe was confirmed with the customer to not require grinding, which enhances the welding strength and reduces labor hours by not grinding. This photo was taken after painting, so it does not show it, but we delivered the frame to the customer after assembling four heavy-duty casters and four level adjusters on the underside of the frame.
