を提供するためになされたものである。 As shown in Fig. 1, the conventional mechanical press is
The frame of the mechanical press, which is the crown 2, column 3, and bed 4, are integrated with a tie rod 5, and a reduction gear is built into the crown 2, and a slide 6 guided by the column 3 is raised and lowered via a crank mechanism. It has a structure. A mold is provided on the bolster 7 and the slide 6 fixed to the bed 4, and a material is supplied to perform the pressing operation. The load during press work is transmitted to the bed via the bolster 7, the slide 6, and the crown 2 via the crank mechanism, and is ultimately received by the tie rod 5. At this time, the bed 4, slide 6, and crown 2 are deformed as shown. Naturally, it is desirable that this amount of deformation be small. Regarding the deformation of the slide 6, the connection points Q and Q between the connecting rod 10 and the slide 6 part are
The closer the points Q and Q are to the loading point by the mold, the more advantageous it is. The closer it is to 5, the more advantageous it is. The present invention was devised in view of this point in order to provide a mechanical press with a structure that minimizes the amount of deformation.

けられている。 In FIG. 2, a reduction gear 11 is attached to the crown 2.
is assembled, and the main gear 12 included in the reduction gear 11 is rotatably held by the crown portion. The connecting rod 10 is fitted into the eccentric portion 12a of the main gear 12. The lower end of the connecting rod 10 is connected to the slide 6 via an adjustment screw 13. The bearing portion P, which is the center of rotation of the main gear 12, is located outside the connection point Q between the connecting rod 10 and the adjustment screw. In other words, point Q is located near the center of the slide 6, and point P is located near the tie rod 5.
本考案は以上のような構成であるので、スライ
