Abstract

PURPOSE:To make strong the frame construction over the entire part by dividing the crown and bed in the divided frames of a large sized press to central part and part corresponding to column and fastening the crown, columns and bed by means of tie rod. CONSTITUTION:A crown 1 is divided to a central part 2 and parts 3 corresponding to column overhanging to the front and rear in both right and left end parts, in a frame of a large sized press constituted of the crown 1, columns 6 and a bed 7. The bed 7 is also divided similarly to a central part 8 and part 9 corresponding to column overhanging to the front and rear in both right and left end parts. Upward stepped part 10 and downward stepped part 11 are respectively provided to the central parts 2, 8, and the central part is engaged with the parts 3, 9 by said stepped parts; at the same time, tie rod 5 penetrated through the part 3, the columns 6 and the part 9 and are securely fastened from above and below. The frame is easily dividable and is provided with the strong construction when assembled.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a split frame for a large press.

“In the past, large presses, especially large transfer presses, were disassembled into the crown, bed, and column when being transported by land, and the width of the crown and bed still exceeded the size limit for road transportation. Therefore, various division methods have been devised. For example, as shown in Fig. 1, the crown (1) of the press is divided into a central part (2) and a column-equivalent part (3) extending from the central part (3). Divide the pedal (4) in the same way, and divide the central part (2) and the column equivalent part (
3), a cock (4) is inserted and positioned, and the crown, column, and bed are assembled by tightening them with tie rods (5). However, the cook (4
) to position the center part (2), and position the column equivalent part (3
) and the bolts alone do not provide a strong structure, and the tie opening, y)" (51) has the disadvantage that the effect of the tightening force cannot be fully demonstrated. The purpose of the present invention is to eliminate this disadvantage, The divided central part of the crown and bed and the column-equivalent part are provided with stepped parts that engage with each other, so that when the tie rods are tightened, the central part is clamped between the column and the column-equivalent part, and is firmly tightened and positioned. The object of the present invention is to provide a split frame for a large press, which can make the entire frame structure rigid.

Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 2(a), (b), and (C), the frame of the press consists of a crown (1), a column (6), and a bed (7). The crown (1) has a central part (2),
The central portion (2) is divided into column-equivalent portions (3) extending forward and backward at both left and right ends. Central part (2)
is provided with an upwardly facing stepped portion 00), and a column-equivalent portion (3
) are provided with downward step portions 00) that engage with each other. There is a crown (1) at a position continuous with the column equivalent part (3).
) is erected on the top surface of the bed (7). The front-to-back width of the central portion (2) of the crown (1) is larger than the inner width of the column (6) in the front-to-back direction;
The central part (2) is supported by the column (6) at both front and rear ends, and is pressed down from above by the stepped part 00) of the column equivalent part (3), and the upper surface of the column (6) and the column equivalent part (3) It is held between. The bet 1 force also has a similar structure to the crown (1), and is divided into a central portion (8) and a column-equivalent portion (9) that overhangs forward and backward from both left and right ends of the central portion (8). The central portion (8) is provided with a downwardly facing stepped portion aυ, and the column-equivalent portion (9) is provided with a soil-facing stepped portion αυ, which engage with each other. The front and back width of the bed (the central part (8) of the force is slightly larger than the front and rear inner width of the column (6), so the central part of the bed (7) is the stepped part of the column equivalent part (9). It is held between aυ and the lower surface of the column (6).The center part (2) of the crown (1) and the column equivalent part (3)
is fixed with bolts, and the bed (center part of the sword (8) and column equivalent part (9) are fixed in the same way.

Column equivalent part (3) of crown (1), column (6),
The tie rod (corresponding to the 7th column (9))
5) The frame of the press is assembled by penetrating it and tightening it firmly from above and below.

Next, we will discuss the effect. The center part (2) of the crown (1)
) can be tightened with the tie rod (5) by setting the distance from the step QO) of the column (3) to the column (6) equal to or slightly larger than the distance from the step 00) of the column equivalent part (3) to the column (6). At this time, the center part (2) of the crown (1) is sandwiched between the step part 00) of the column equivalent part (3) and the top surface of the column (6), so a strong frame structure is obtained, and the tie rod (5 ) can take full advantage of the preload effect created by tightening. The bed (same as for the sword), the center part (8) is sandwiched between the stepped part 01 of the column equivalent part (9) and the lower surface of the column (6), so the strong frame structure is changed, and the entire frame of the press is The structure is strong and the structure is strong.
51(7) Preload effect can be utilized.

As is clear from the above description, according to the present invention, compared to conventional split frames, the entire frame structure when assembled can be made stronger, and the preload effect of the tie rods can be fully utilized. The split frame is convenient for land transportation, and the practical effects and advantages are extremely large.
