させて押し曲げ成形する加工が施されている。Prior Art For example, in a workpiece such as a guide rail L formed into a substantially C-shaped cross section as shown in Fig. 6, an assembly member such as a guide roller R as shown in Fig. 7 is inserted inward from one end. In order to make it easier to handle, the side faces f 1 , f 2 and the back face f 3 on the end side are expanded as shown by two-dot chain lines and then pressed and bent.

つ端部の曲げ加工装置を用いて行なわれている。 Conventionally, this press-bending process involves bending the end portion of the guide rail L with a fixed die 1 provided with a concave receiving groove 1a that supports the side surface f 1 , f 2 to the back surface f 3 as shown in FIGS. 8 and 9. This is done using processing equipment.

The end portion of the guide rail L supported by the receiving groove 1a is press-formed by inserting a horizontal punch 2 having a tip end face aligned with the receiving groove 1c into the groove. In addition, in this bending device, a horizontal punch 2 is slidably supported by guide plates 3 and 4, and a horizontal shaft 5 protruding from the rear thereof is inserted through the plate surface of a stopper plate 6 to be aligned on the axis. The horizontal punch 2 is pulled and deflected by the fitted compression spring 7, and the horizontal punch 2 is moved forward against the compression spring 7 by the downward movement of the cam 9 attached to the cam plate 8, thereby making it horizontal.

も容易に行い得るようになる。Function In this workpiece end bending device, when the workpiece is inserted into the receiving groove of the fixed die from the longitudinal direction and placed, the tip side of each expansion punch is located horizontally inside the end of the workpiece, and the pressing punch As it moves downward, it inserts itself between the expansion punches and moves the expansion punch to the left and right, so that the expansion punch is installed at the tip side on the open end side of the receiving groove on the left and right sides of the workpiece. At the same time, the slanted surface provided on the lower end side of the pressing punch presses against the slanted bottom surface provided on the open end side of the receiving groove on the back of the workpiece, and the end side of the workpiece is pressed against both the side surface and the back surface. Expansion bending can now be done in the same process, and since the expansion punch is rotatably mounted, it can be rotated upward after bending the end of the workpiece, allowing insertion from the longitudinal direction when placing the workpiece. Since the workpiece can be hooked on the tip side, lifted upward from the fixed die, and then pulled out from the expansion punch, the workpiece can be easily removed.

The fixed die 11 has a concave receiving groove 12 that supports the left and right side surfaces of the workpiece from the back side, and this receiving groove 12 is formed by diagonally notching the edge of the open end so that the open end side conforms to the bent shape of the workpiece. The oblique side surfaces 1a, 1b and the bottom surface 1c are correspondingly widened. A pair of left and right expansion punches 13 and 14 are mounted on the plate surface of the base plate 10, with their tips positioned within the recess on the open end side of the receiving groove 12. Each of these expansion punches 1
3 and 14 are inclined surfaces 13 whose respective tip sides are relatively aligned with the oblique side surfaces 1a and 1b provided on the open end side of the receiving groove 12.
leg portions 13b and 14b are provided to protrude downward from approximately the middle of the base plate 10 to hold the distal ends thereof horizontally. In addition, each expansion punch 13,
14 is mounted so that it can pivot up and down by supporting the other end with a support shaft 15, and furthermore, the support shaft 1
Compression springs 18 and 19 are fitted on the axis of the support shaft 15 and disposed between the bracket plates 16 and 17 of the support shaft 15, so that the support shaft 15 is elastically deflected in the direction toward the support shaft 15. Each punch 1
A spacer 20 mounted on the axis of the support shaft 15 is arranged between 3 and 14, and this spacer 20
They are held parallel to each other with a predetermined spacing between them. At a position corresponding to the interval, a pressing punch 22 is attached above to protrude from the lower surface of a punch plate 21 which is moved up and down by a drive cylinder or the like as shown in FIGS. 2 and 3. This pressing punch 22 has a sloped surface 22a on the lower end side that is relatively aligned with the sloped bottom surface 12c provided on the open end side of the receiving groove 12, and the relative edges of the expansion punches 13 and 14 are expanded with a somewhat diagonal notch. Thick plate portion 22b that substantially corresponds to the opposing spacing and thick plate portion 22 that cuts into the gap between expansion punches 13 and 14 and moves them apart to a predetermined position.
It is formed by having c.

るようになる。 In the workpiece end bending device configured as described above, when one end of the workpiece is inserted into the fixed die 11 from the longitudinal direction so as to be aligned with the open edge of the receiving groove 12, an expansion punch is formed inside the one end side. 13,1
4 will now be located. When the pressing punch 22 is moved downward in this placed state, the relatively narrow plate portion 22b on the lower end side of the expanding punch 1
3 and 14 and resisting the compression springs 18 and 19, each expansion punch 13,
14 is moved away from the left and right along the support shaft 15, and the relatively wide plate thickness part 22c becomes the expansion punch 13,
As shown in FIG.
The side surfaces f 1 and f 2 of the workpiece L are expanded and formed by pressing f 1 and f 2 so as to press them against the left and right oblique side surfaces provided on the open end side of the receiving groove 12 . At the same time, the inclined surface 22a of the pressing punch 22 presses the back surface f 3 of the work L and presses against the oblique bottom surface provided on the open end side of the receiving groove 12, so that the back surface f 3 of the work L is also bent downward and expanded. Becomes able to open mold. Therefore, with the downward movement of the pressing punch 22, the bending process can be performed on the end side in one step so as to expand both the left and right side surfaces f 1 , f 2 and the back surface f 3 of the work L. . In addition, after this bending process, the press punch 22
When the expansion punches 13 and 14 are moved upward, the compression springs 18 and 19 return the expansion punches 13 and 14 in the approaching direction, but since their tips are located inside the workpiece L, the support shaft 15 is moved as shown in FIG. If the workpiece L is rotated upward from the center, the workpiece L can be hooked to the tip side and taken out from the receiving groove 12 of the fixed die 11, so that the workpiece L can be moved into the expansion punch 1 in this state.
It can be easily removed by pulling it out from 3 and 14.
