DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0019]
The extruded shape member 10 for the guide rail of the moving partition is formed by forming left and right support portions 11a and 11a on the bottom side of a rectangular tube-shaped main body portion 11 and vertically extending a leg 12 on each support portion 11a (FIG. 1). ).
[0020]
Supporting portions 11a and 11a are connected to the thick base of the main body portion 11 via a reinforcing portion 11b. The support portions 11 a and 11 a are formed on both outer sides of the leg portions 12 and 12, and the reinforcement portion 11 b is formed between the leg portions 12 and 12. In addition, the reinforcing portion 11b is formed with a thin portion 11c between each support portion 11a via upper and lower grooves 11d and 11d having a right triangle shape.
[0021]
The leg portions 12, 12 are respectively suspended from the distal end side of the support portion 11a, and an outward flange 12a is formed at the distal end. The ends of the leg portions 12 and 12 are connected via a reinforcing portion 12b, and the reinforcing portion 12b is continuous with the leg portions 12 and 12 via thin-walled portions 12c and 12c. In addition, each thin part 12c is formed through the grooves 12d and 12d of the upper and lower cross-sectional right triangle shape similarly to the thin part 11c.
[0022]
Such an extruded profile 10 can be bent at once by a vendor apparatus BD including a copying mold BD1, a bending mold BD2, a holding mold BD3, and a mandrel BD4 (FIGS. 2 and 3).
[0023]
The copying mold BD1 is provided with flanges BD1a and BD1a on the upper and lower sides of a cylindrical mold body BD1b. The outer periphery of the mold body BD1b is formed in a predetermined uneven shape in accordance with the side surface shape of the extruded profile 10. The bending mold BD2 and the holding mold BD3 each have a front surface formed in a predetermined concavo-convex shape in accordance with the side surface shape of the extruded shape member 10. The bending die BD2 is mounted on the upper turning arm BDb via the presser block BDa so as to be movable back and forth in the radial direction of the copying die BD1. The upper turning arm BDb, together with the lower turning arm BDb and the connecting frame BDc, can turn around the axis of the copying die BD1.
[0024]
The holding die BD3 is mounted on a turning arm BDd that can turn around the axis of the copying die BD1 via a pressing block (not shown) so as to be movable back and forth in the radial direction of the copying die BD1. The mandrel BD4 is mounted on a moving frame (not shown) via a drive rod BD4a. The moving frame that supports the mandrel BD4 is movable around the axis of the copying mold BD1, and is equipped with a stopper BD5. The mandrel BD4 can be driven back and forth via the drive rod BD4a.
[0025]
Vendor device BD has bending mold BD2 and holding mold BD3 adjacent to each other (FIG. 4), and sets one end portion of extruded profile 10 between copying mold BD1, bending mold BD2 and holding mold BD3. The mandrel BD4 is accommodated between the bending mold BD2 and the copying mold BD1 in the apparatus 10, and the stopper BD5 is set at the open end of the extruded profile 10. Next, the bending die BD2 and the holding die BD3 are advanced toward the copying die BD1 to clamp the extruded shape member 10, and the bending die BD2 is turned around the copying die BD1 (in the direction of the arrow K1 in the figure), and the mandrel. While rotating the drive rod BD4a and stopper BD5 of BD4 (in the direction of arrow K2 in the figure), pull out the mandrel BD4 to the stopper BD5 side through the drive rod BD4a (in the direction of arrow K3 in the figure) to push out the extruded profile. 10 can be bent at once around the copying mold BD1 (two-dot chain line in the figure).
[0026]
However, the mandrel BD4 at this time is moved relative to the extruded profile 10 in accordance with the movement of the bending die BD2, and is always positioned between the bending die BD2 and the copying die BD1. The extruded shape member 10 is sufficiently reinforced through the reinforcing portions 11b and 12b, and can be kept in a regular cross-sectional shape without being inadvertently crushed.
[0027]
The extruded shape member 10 bent by the vendor device BD removes the reinforcing portions 12b and 11b along the thin portions 12c, 12c, 11c, and 11c by, for example, a cutter FC of a vertical milling device (FIG. 5). At this time, the cutter FC may cut the reinforcing portions 12b and 11b individually, or may cut the reinforcing portions 12b and 11b all at once.
[0028]
When the reinforcing portions 12b and 11b are removed and the support portions 11a and 11a and the leg portions 12 and 12 are opened, the extruded shape member 10 is completed as a curved guide rail R (FIG. 6). The guide rail R accommodates a runner RR that suspends a partition panel (not shown), supports the runner RR via the left and right support portions 11a, 11a, and can guide the runner RR for travel.
[0029]
In the above description, the extruded shape member 10 after bending can be improved in strength by performing appropriate quenching before or after the removal of the reinforcing portions 11b and 12b, and the cutting performance by the cutter FC can be improved. . Further, the guide rail R may be subjected to a surface treatment such as alumite treatment.
[0030]
[Other embodiments]
The curved guide rail R shown in FIG. 6 can be used as a guide rail piece RA and combined with another linear guide rail piece RB to form a branching guide rail R (FIG. 7).
[0031]
The curved guide rail piece RA is cut along the cutting line Ca1 from the end portion to the intermediate portion (FIGS. 8A and 8B), and the linear guide rail piece RB is cut from the end portion to the intermediate portion. And cut along the cutting line Cb1. Note that the cutting line Cb1 has the same shape as the cutting line Ca1, and therefore the guide rail pieces RA and RB are cut so as to be complementary to each other.
[0032]
The guide rail pieces RA and RB can form a branching guide rail R by abutting the cut surfaces formed by the cutting lines Ca1 and Cb1 (FIG. 3C) and welding and joining together. . Since the branch guide rail R has only a welded portion where the guide rail pieces RA and RB are joined, welding distortion is small and a highly accurate product can be produced.
[0033]
The curved and linear guide rail pieces RA and RB may be cut along the linear cutting lines Ca1 and Cb1 and joined together (FIG. 9A). Moreover, the guide rail R for branching may join the guide rail pieces RA and RB to form two branch portions (FIG. 5B). Furthermore, the guide rail R for branching may be combined with curved guide rail pieces RA and RB ((C) in the figure).
[0034]
