It shows the cutting process of the rail sequentially.

First, the holder rail processing apparatus 1 for a wiper according to the present invention, as shown in Figures 1 to 4, the rail portion 110 for binding with the rubber blade on the bottom, the binding with the connecting bracket on the upper surface The upper surface of the holder rail for the wiper formed with a guide 120 for the cutting to a predetermined interval and depth to form a cutting unit 130 on the upper surface of the holder rail 100 for the wiper.

The apparatus 1 is basically a cutting part including a blade drum 22 having a plurality of disc-shaped cutters 22a disposed on the outer circumference of the drum body by being rotated in one direction by receiving rotational force from the electric motor 21. 20; The jig portion 30 composed of the supply jig 31, the cutting jig 32, and the discharge jig 33, in which the guides 31a, 32a, and 33a are horizontally disposed on the upper surface, forms a structure. It is a structure installed on the upper surface of the frame (10).

Here, the cutting part 20 including the electric motor 21 and the blade drum 22 is laterally disposed in the second half of the frame 10, as shown in Figure 2, the blade of the cutting part 20 Both ends of the drum 22 are supported by the rotary bush 23 to maintain a state spaced apart from the upper surface of the frame 10 by a predetermined interval.

And the cutting jig 32 which comprises the jig part 30, the supply jig 31, and the linear guides 31a, 32a, 33a arrange | positioned laterally to the discharge jig 33 are the wiper holders. As the rail part 110 of the rail 100 enters, as shown in FIG. 3, the tip ends 31a-a, 32a-a, and 33a-a are manufactured in a pointed taper shape, and the holder rail 100 for the wiper 100 is formed. Rail portion 110 of the) is configured to be more easily inserted through the tapered end.

In addition, the guide 32a formed in the cutting jig 32 has a vertical reference groove 32b formed therein as shown in FIG. 1, and has a reference bar having a linear protrusion 34a formed in a longitudinal direction on a bottom thereof ( The BAR) 34 is configured to be positioned at the correct position.

Here, the reference bar 34 physically supports the tip of the wiper holder rail 100 that enters along the guide 32a, thereby positioning the wiper holder rail 100 in the guide 32a at a proper position. Perform the function.

On the other hand, the supply jig 31 and the discharge jig 33 is provided on both sides of the cutting jig 32 is made of a fixed type fixed to the first half of the frame 10, the supply jig 31 and the discharge jig The cutting jig 32 provided between the 33 is bound to the piston 41 of the pneumatic cylinder 40 provided in the longitudinal direction in the latter half of the frame 10, and is longitudinally moved by advancing and retracting the piston 41. It is made of a movable type which is conveyed and positioned in the first or second half of the frame.

In this embodiment, the guide block 11 protruding in the longitudinal direction is provided on the upper surface of the frame in which the cutting jig 32 is placed, and the guide rail recessed in the longitudinal direction on the bottom of the cutting jig 32. (32) is formed so that the cutting jig (32) forms a guide structure on the upper surface of the frame (10). Accordingly, by the pneumatic cylinder 40, the piston 41, the retraction action, the cutting jig 32 provided in the guide structure on the upper surface of the frame 10, can be more stably displaced.

That is, when the piston 41 of the pneumatic cylinder 40 is retracted, the cutting jig 32 provided on the upper surface of the frame 10 is transferred to the second half of the frame 10 along the guide block 11, so that cutting When the piston 41 of the pneumatic cylinder 40 moves forward and the pneumatic cylinder 40 moves forward, the cutting jig 32 provided on the upper surface of the frame 10 is a frame ( It is conveyed to the first half of 10) to form a state in which the supply jig 31 and the discharge jig 33 are arranged side by side.
