METHOD FOR WELDING FINISHED PRODUCT OF PRESS FRAME

PURPOSE:To economize large-sized machine tool installations and to enable removal of the trouble in transportation and repair in an installation place by working individually the respective parts of the frame of a press machine and welding the parts to a finished product in the installation place. CONSTITUTION:Holes having precise accuracy are preliminarily worked to base plates 4 so as to meet the outside diameter of bearing members 2 of the finished product after welding of a crown 1 which is a part of the frame of a press. On the other hand, the members 2 are preliminarily finished to the finished product size. The members 2, 2 are inserted into the plates 4, 4 and fitting plates 5 are fitted respectively to the members 2, 2. Discs 6 are pressed thereto and long screw bars 7 are passed through the discs and after the long screw bars 7, 7 are screwed into a cylindrical member 9, the respective parts are fixed by means of nuts 8, 10. The distance between the members 2 and 2 is precisely adjusted to the prescribed value. While the members 2, 2 are held by restraining members 3, the plates 4, 4 and the outside diameter parts of the members 2, 2 are welded.
