Abstract

PURPOSE:To size a metallic blade into a normal shape easily, speedily, and automatically by rotating the metallic blade in a deformed shape between sizing rolls set at specific positions. CONSTITUTION:The metallic blade 1 which is formed by pressing a steel plate and in the deformed shape is rotated by the rotation of a main shaft 2. When the vane part 5 of the metallic blade deforms, the sizing rolls 6 and 6' for pressing the vane part 5 are fitted to the front and rear parts of the vane part 5. As the metallic blade 1 is rotated, the vane part 5 contacts the sizing rolls to receive a bending load from the sizing rolls and then deforms to be sized into the normal shape. In this case, the sizing rolls are not fixed, but put closer to the vane part by continuously varying the pressing-in extent according to the reformed state of the vane, sizing the shape without excessiveness.

、形状検査と修正が必要上なる。[Technical background and problems] Metal blades used in blowers and the like are integrally formed from a single steel plate by press forming. In this process, the metal blade, which is a molded product, is not formed into the shape of the press mold due to uneven plate thickness and variations in material properties in the blade part, resulting in deviations in the blade shape and quality. There is a lot of variation in the results. For this reason, all products require shape inspection and correction.

In FIG. 1, a metal blade (1) is centered and restrained between a main shaft (2) and a six pusher (3). At this time, the wide press (3) applies a load in the direction of the main axis (2) and the metal blade (1
) is fixed and rotates following the main shaft (2). This metal blade (1) also rotates. In addition, the wing part of the metal feather (1) (
5) A correction roller (
6) is provided. 1F, the roller (6) has a function of being movable parallel to the rotation axis of the main shaft (2), that is, the rotation axis of the metal blade (1). In addition, in this embodiment, the straightening roller (6γ is provided with a button on the back side of the metal blade (1), and the blade portion (5) is placed on the front and back sides of the straightening roller (6γ) having the same structure as the E roller (6) described above. It is possible to perform shape straightening E from both sides.

変形を受は適ＩＥ形状に矯正される。If the shape of the blade part (5) of the metal blade (1) tends to shift, as shown in Figure 2,
The tip of the metal blade (1) is fixed at a predetermined position so that the blade portion (5) has an appropriate shape, and the main shaft (2) is driven to rotate the metal blade (1) in the direction of the arrow. At this time, one end (5)' of the blade part (5) (!: the distance from the tip of the roller is as shown in Fig. 2 (a)
Assume that h is as shown in . As the metal blade (1) rotates, the blade part (5) moves in the direction of the arrow, as shown in Fig. 2(b).
), it comes into contact with the straightening roller (6). When the wing part (5) further moves and passes through the straightening iE a-ra (6), the wing part (5) receives the bending load from the straightening iE o-ra (6) and is deformed (Fig. 2K). Shown here 7. Wing part (5)
The distance between the one end (5)' and the correction roller (6)7 is eliminated. As described above, by rotating the metal blade (1), the blade portion (5) is sequentially corrected from bending deformation by the correction roller (6) into an appropriate IE shape.

The respective wing parts (5) are (a), (b), (
C), (d) Scratch, the tip and wing portion (5) of the straightening roller (6) fixed in a predetermined position as shown in FIG.
) is ba, hb, h, respectively.
c, hd. Therefore, rotate the metal blade (1),
FIG. 3 shows the relationship between the load on the correction roller (6) and the bending deformation when a bending load is applied to each chord part by the correction roller (6). h'a, h'b, h'c,
h'd, each wing part (5) is a straightening roller (6)
This is the distance from one end (5Y) of each wing portion (5) on the tip of the straightening roller (6) after the shape has been corrected by receiving a bending load from the straightening roller (6). (It is shown on the horizontal axis of the graph.) Note that the vertical axis indicates the roller load applied to the correction roller (6).
As shown in the figure, the deviations in the shape of the wing portion (5) before correction were ha, hb, he, hd, but by performing the correction as shown in Fig. 2, it became h'a, h'b
, h'c, h'd, 5, it can be seen that deviations and variations in the shape of the blade portion (5) become smaller.

In this case, straightening IF is performed. After the edge wing part (5) passes the correction roller, i'a, h'b, h'c, h' due to springback
d occurs and the appropriate shape cannot be obtained. Therefore, taking this springback into consideration, if the position at which the correction roller (6) is fixed is made larger than the amount of deformation that should be corrected in the wing portion (5),
This allows the deformed state of the wing section (5) after springback to be in the correct position.

Since the metal blade (1) will dig in when performing GYI, it is necessary to rotate the metal blade (1) in the opposite direction if straightening is performed from the back side.
