ずるという欠点があつた。 Conventionally, in the clamp/unclamp drive device of a transfer press, the inner width of the feed bar has been changed depending on the width of the product to be pressed. To do this, a drive unit housing a drive mechanism that provides clamping and unclamping movements to the feedbar is slid in the longitudinal direction of the machine, but because the inclination of the vertical rod connected to the rack provided in the drive unit changes, the rack moves vertically. There was a drawback that the timing of the clamp/unclamp movement (and lift/down movement) and the slide movement was inconsistent.

The inner width of the receiving members 24, 24 is expanded. At this time, the distance between the lever 3 and the drive unit 7 is l 1 to l 2
Changes to If l1 is left as is, the rack 10 will be pulled up slightly, causing a shift in the positional relationship between the rack 10 and the pinion 11. Since the structure of the drive unit 7 and the clamp unit 8 is such that the positional relationship is fixed as described above, any deviation in the positional relationship between the rack 10 and the pinion 11 remains as it is in the receiving members 24, 2.
This appears as an inner width error and timing error of 4.
