The invention relates to an improvement of a device for adjusting the degree of attachment of a pair of left and right guide rollers that guide a pressed steel, and more specifically, a degree of attachment adjustment mechanism that advances and retreats in a direction perpendicular to a pass line in order to adjust the degree of attachment. The invention relates to a roller holder drawing mechanism that presses rear end portions of roller holders on both sides that support the guide roller to a pair of threaded spindles on both sides of the roller holder.

退させる作業には、甚だしい障害となる。 In the conventional entrance side guide device (roller guide), as a means for pressing the rear end of the roller holder into contact with the outer end of the threaded spindle of the conjugation degree adjustment mechanism, a guide roller 3' is installed at the tip as shown in FIG. 8 of the attached drawings.
A tension spring S' is stretched between the rear end extensions 23', 23' of roller holders 2'a, 2'b on both sides, which are provided with roller holders 2'a, 3'b, and pivotally connected by fulcrum pins 10', 10'. It was common practice to press the ends of the push bolts 6', 6' against the outer ends of the threaded spindles 5', 5'. This tension spring S' is located at the rear of the roller guide main body, crossing the upper surfaces of the rear brackets 16', 16' on both sides, so it often gets in the way of various operations, and especially prevents the guide rollers from collapsing. This poses a serious obstacle to the operation of operating the ratchet handle 45' to rotate the female threaded cylinder and move the threaded spindles 5', 5' forward and backward for adjustment.

の圧接力を確実に維持する。 On the other hand, correspondingly, the roller holder 2 (a, b
A push bolt 6 (common to both a and b) is screwed onto the upwardly protruding portion 24 provided at the rear end of the push bolt 6 (common to both a and b) with its tip 60, which forms the force point P between it and the tip 50 of the screw spindle, facing the screw spindle. ing. The push bolt 6 shown in FIG. 6 has a hollow portion 61 at the central rear end portion of its shaft body, the rear end of which opens toward the outer surface of the roller holder, and the front end of which is closed with an end wall 66.
A through hole 62 having a relatively large diameter is provided in the end wall 66 along the axis. And hollow part 6
1, loosely pass the tip of the mooring member (long bolt) 63 to be inserted into the through hole 62, and screw the threaded portion of the tip into the long bolt screw hole 55 of the threaded spindle. A coil spring S housed in the hollow portion 61 is compressed between the portion 64 and the end wall 66. Due to this compression (deformation), the tips 50, 60 of the threaded spindle and push bolt are pressed against each other. The inner diameter of the hollow portion 61 is sufficiently large, and the inner diameter of the through hole 62 is large enough to form a force point P with the threaded spindle 5 and not hinder the support of the spring 65. In adjusting the coupling degree, the threaded spindle 5 moves back and forth on the axis of the female threaded cylinder in the direction perpendicular to the pass line, but the fulcrum pin 10
The push bolt 6 on the roller holder, which rotates around a and 10b, is displaced along an arc like an arrow passing through the force point P. As a result, when the screw spindle 5 advances or retreats with the position where the axes of the screw spindle 5 and the push bolt 6 coincide (FIG. 6) as the neutral position, the rear end of the roller holder moves to the seventh position.
The push bolt 6 is moved as shown in the figure by moving in a V-shape or an inverted V-shape as indicated by 24a and 24b in Figures 24a and 24b. However, since the hollow portion 61 and the through hole 62 of the push bolt have sufficient size as described above, they do not interfere with the long bolt 63.
The spring 65 also reliably maintains the pressure contact between the tip of the push bolt and the outer end of the threaded spindle with only a slight distortion in shape.

させることにより強弱調節できる。 In FIG. 9a, the screw spindle 5 has a thin through hole 56 in its axial center, and one end is attached to a stop plate 63.
The tip of the thin rod anchoring member 63a anchored to the rear end of the screw spindle in step 1 is inserted into the hollow portion 61 provided at the rear end of the shaft of the push bolt 6.
A coil spring S housed in the hollow portion 61 is compressed between the end wall 66 and the receiving plate 67 which is locked with a nut 671 at the other end. The compression (deformation) of the spring S presses the tips 50, 60 of the threaded spindle 5 and push bolt 6 against each other as before. This pressing force can be adjusted in strength by moving the nut 671 through the thread groove 632.

As in the previous example, the coil spring S housed in the hollow portion 61 of the push bolt shaft is expanded. The push bolt side end of the coil spring S is locked to the rear end of the push bolt 6 via a locking nut 651 and a locking plate 65 that are screwed into the threaded portion S1 at the tip thereof. Needless to say, the extension of the spring S causes stress that causes the ends of the screw spindle 5 and the push bolt 6 to press against each other. 610 is a recessed portion for preventing the locking plate 65 etc. from protruding from the rear end of the push bolt.
