Description

[Detailed Description of the Invention] [Technique of the Invention] This invention relates to a straightening device for continuously fed workpieces such as roll-formed products.

[Prior art]

2. Description of the Related Art Straightening devices are known for correcting deformations such as bending and twisting of a workpiece made by roll-forming a metal strip into a predetermined cross-sectional shape to obtain a molded product having a predetermined shape. Figure 1 is a perspective view of a conventional orthodontic device;
The figure is its front view.

In the figure, 1 is a workpiece, which is continuously fed out from a roll forming machine 2 in the A direction. 3 is a support plate fixed on the base plate 4; 5 is a rotary plate provided on the support plate 3 so as to be rotatable in the B direction, that is, in the circumferential direction, and is adjusted through an arc-shaped guide groove 6 provided on the periphery. A screw 7 is screwed into the support plate 3. A slide guide 8 is provided on the rotary plate 5, and a slide plate 9 is provided to engage with the slide guide 8, and a screw shaft 10 is engaged with a bracket 11 so as to be able to slide in the C direction, that is, in the left and right direction of the work axis. ing.

A U-shaped support frame 12 with an open bottom stands up from both sides of the slide plate 9, and a holder plate 13 is provided so as to move up and down in the D direction using pillars 12a and 12b on both sides of the support frame 12 as guides. , the screw shaft 14 extending upward from this is the support frame 12
is engaged with the beam portion 12c. A die holder 15 is provided approximately in the center of the holder plate 13 so as to be rotatable in the E direction about the workpiece axis, and a worm shaft 17 that engages with a gear 16 provided on the die holder 15 projects from the support 12a. It is provided. Note that the worm shaft 17 engages with the gear 16 inside the holder plate 13, but this portion is shown in solid lines for ease of understanding. A die 18 is provided in the center of the die holder 15, and the workpiece 1 is inserted therethrough.

In the above configuration, the workpiece 1 continuously sent out from the roll forming machine 2 is inserted through the die 18 to correct deformation of the workpiece 1. In this case, when the adjusting screw 7 is loosened and the rotating plate 5 is rotated in the direction B, the angle of the die 18 changes from side to side with respect to the workpiece axis. Further, when the screw shaft 10 is rotated and the slide plate 9 is slid in the C direction, the die 18 moves left and right with respect to the workpiece axis. By combining these, bending, warping, etc. in the left and right direction of the work 1 can be corrected.

Next, when the screw shaft 14 is rotated to move the holder plate 13 in the D direction, the die 18 moves up and down with respect to the workpiece axis, and the vertical bending, warpage, etc. of the workpiece 1 is corrected. Also, worm shaft 1
When the die holder 15 is rotated in the E direction by rotating the die 18, the angle of the die 18 changes with respect to the normal position of the work 1, and the twist of the work 1 is corrected.

However, in the conventional workpiece straightening device as described above, the vertical deformation of the workpiece 1 is corrected only by the vertical movement of the holder plate 13. Although deformation can be easily corrected, large deformations in the vertical direction such as warpage cannot be completely removed even if the holder plate 13 is moved to the upper or lower limit.

[Purpose of invention]

This idea was developed to eliminate the above-mentioned drawbacks. By providing a swingable support plate and tilting the entire device with respect to the workpiece axis, it is possible to easily handle large deformations in the vertical direction of the workpiece. The object of the present invention is to provide a workpiece straightening device that can straighten a workpiece.

[Structure of the idea]

This idea consists of a support plate that is swingably supported on a rotating shaft provided on a base so as to be inclined with respect to the workpiece axis, and that is maintained in an inclined state by a holding member, and a support plate that rotates along the support plate. A rotating plate that is movable, a sliding plate that is slidable in the left and right directions of the workpiece axis relative to the rotating plate, and a holder that is movable up and down along a support frame that rises from the sliding plate. This workpiece straightening device is characterized by comprising a plate, a die holder rotatably provided on the holder plate to be rotatable about the workpiece axis, and a die attached to the die holder and through which the workpiece is inserted.

[Example of idea]

This invention will be explained below with reference to embodiments of the drawings. FIG. 3 is a front view showing an embodiment of this invention, and the same reference numerals as in FIGS. 1 and 2 indicate the same or corresponding parts. Reference numeral 19 denotes a support plate fixed on the base 4, and the support plate 3 is tilted in the F direction, that is, with respect to the workpiece axis, by a pin 21 serving as a rotating shaft supported by brackets 20 rising from both left and right sides of the central part. It is supported so as to be able to swing in the direction shown in FIG. Adjustment screws 22 and 23 as holding members are screwed onto both sides of the support plate 3 in the front and back direction, and the tips thereof are adapted to abut on the support base 19, respectively. The other configurations are the same as those in FIGS. 1 and 2.

In the above configuration, when one of the adjustment screws 22 and 23 is loosened and the other is screwed in, the support plate 3
The die 18 is swung in the F direction using the rotation axis 1 and held in a state inclined with respect to the workpiece axis, thereby causing the die 18 to rotate in a direction intersecting the workpiece axis.
By combining the movement of the support plate 3 with the vertical movement of the holder plate 13, all vertical deformations such as bending and warping of the workpiece 1 can be corrected. Other operations are similar to those in FIGS. 1 and 2.

FIG. 4 is a front view of another embodiment, and FIG. 5 is a partially exploded perspective view thereof. The bracket 20 is provided at one end of the support base 19 and has a pin 2 as a rotating shaft.
1 supports a bracket 24 provided at one end of the support plate 3, so that the support plate 3 can swing in the G direction. An adjustment screw 25 serving as a holding member is screwed to the other end of the support plate 3, and an engagement member 25a at the tip thereof is an engagement member swingably provided at the other end of the support base 19. 26. 27 and 28 are lock nuts.

In the above configuration, the lock nuts 27, 28
When the adjustment screw 25 is loosened and the adjustment screw 25 is rotated, the support plate 3 swings in the G direction using the pin 21 as the rotation axis and is held in a tilted state with respect to the workpiece axis, thereby causing the entire device to swing in the F direction. However, the die 18 rotates in a direction intersecting the workpiece axis.

In the above description, the swing mechanism, support mechanism, etc. of the support plate 3 are not limited to those shown in the drawings. Further, the present invention can be applied to a straightening device for roll-formed products such as deformed materials and other continuously fed workpieces.

[Effect of idea]

According to this invention, since the support plate is swingably provided, vertical deformation of the workpiece can be easily corrected, and the swinging mechanism thereof can also be simplified.
