て調整し得るよう構成する。A bearing 1 in which a nut 16 having a reverse thread corresponding to the bearing 12b is screwed and the nut 16 is provided on the frame 14 side.
The nut 16 is rotatably supported by a bushing 18 and an A-m wheel 19 is fixed to the outer periphery of one end of the nut 16, and a worm 20 driven by a drive device (not shown) is meshed with the worm wheel 19. , by rotation of the nut 16, the threaded part 1 is screwed into the nuts 1 to 16.
The distance between the molds 21a and 2ib attached to the sliders 7a and 7b can be adjusted by moving the rods 13a and 13b closer and further apart in the left-right direction via the rods 2a and 12b and changing the positions of the shafts 9a and 9b of the yokes 4a and 4b. It is configured so that it can be adjusted according to the width of the rolled material 22.

離反移動する。従って、金型２１ａ。In the opposed type press having such a configuration, when performing width reduction of the rolled material 22, the drive device 1 is driven to rotate the eccentric shaft 2.
is driven to rotate around the rotation axis O. When the eccentric shaft 2 rotates, the connecting rod 3a pivotally connected to the eccentric shaft 2,
Since the rotational axes 01 and 02 of the rotational axes 01 and 02 of the rotational axes 3b are shifted by 180 degrees across the rotational axis O, the rotational axes 3b move in opposite directions in the left and right directions, and this movement is repeated as a reciprocating motion. As the connecting rods 3a and 3b reciprocate in the left and right direction, the yoke 4a
, 4b rotate around the shafts 9a, 9b, so the yoke 4
a, 4b, and the sliders 7a, 7b approach in the left-right direction while being guided by the guide members 6a, 6b.
Move away. Therefore, the mold 21a.

, 4b, a rod 13a connects the shafts 9a and 9b.
, 13b and the nut 16 as a tensile force, and at the same time acts on the connecting rods 3a, 311 as a compressive force. Therefore, no excessive moment is applied to the frame 14. Therefore, the frame 14 can be made smaller. Furthermore, since the connecting rods 3a and 3b are driven by a single drive device 1, the entire device can be downsized.

It is obtained by rotating 0. That is, when the worm 20 rotates, the nut 16 rotates through the rotation of the worm wheel 19 fixed to the outer peripheral end of the nut 1G. Oaks 1 to 1G have shafts 9a and 9 of husbandry yokes 4a and 4b.
Threaded portions 12a and 12b at the tips of rods 13a and 13b pivotally connected to
Since rods a, 12b are reverse threaded, rod 13a
, 13b move in opposite left and right directions. Therefore, the yokes 4a, 4b rotate around the lower end bins 5a, 511 as fulcrums, and the slider 7a.
