Description

Detailed Description of the Invention Technical Field The present invention involves partially cutting and removing the flange portion of a sash that has been bent and formed into a predetermined cross-sectional shape, and removing only the necessary portion of a retainer portion that is formed upright on the plane of the main body. This invention relates to a vehicle sash processing device that presses and folds a sash into a flat shape.

BACKGROUND ART Normally, as shown in Fig. 1A, a sash for a vehicle is formed by bending the body part a to the flange part b into a roughly J-shaped cross section, and forming a retainer part c upright on the plane of the main body part. is used.
When installing this sash on the door panel,
In order to insert and fix the sash into the door panel at the end of the sash, the flange b that contacts the door panel components is partially removed as shown in Figure 1B, and the sash is fixed to the glass frame on the axis with screws. Remove the flange part _c1 of the retainer part c, which is curved into a C-shape, and twist it to the sash body.
Figure 1B shows the retainer part _c2 where Ld is installed.
Cutting down and shaping as shown in C is done.

This machining process is carried out by loading and unloading the sash into separate jigs for each machining process, which requires an extremely large number of man-hours and is _time -consuming. Variation tends to occur in the dimensional relationship with the cutting and removal part of b.
There is also a risk of damaging the surface of the sash when it is taken in and out of each jig.

DISCLOSURE OF THE INVENTION An object of the present invention is to provide a processing device for a vehicle sash that is configured to process both the cutting of the flange portion and the cutting down of the retainer portion in one step in order to eliminate the above-mentioned drawbacks. .

That is, in the vehicle sash processing apparatus according to the present invention, there is provided a receiving die on which the sash is placed with the retainer portion facing upward on the die plate side, a holding die that supports the sash with clamping pressure, and a holding die that supports the sash with the retainer portion facing upward. A hook-type punch is arranged to cut off the sash, and a first cam that drives the presser die forward on the punch plate side and a second cam that drives the hook-type punch backward. A knockout bar is attached to press down the cut down retainer part, and each is configured to act on the sash with one downward movement of the punch plate.

BEST MODE FOR CARRYING OUT THE INVENTION The structure of this vehicle sash processing apparatus will be described based on the second illustrated embodiment. The structure includes a punch plate 1 that can be moved up and down, and a die plate that is fixedly arranged below the punch plate 1. 2. The punch plate 1 includes a first cam 3, a second cam 4, a push-cut punch 5 for partially cutting the flange portion b (see FIG. 1) of the sash, and a cut-down portion of the retainer portion c (see FIG. 1). A knock-out bar 6 for pushing down is attached. Also. The die plate 2 includes a receiving die 8 supported by a die holder 7, a presser die 9 that supports the portion of the retainer portion c that will not be cut down, and a hook type that passes the presser die 9 and retreats to cut off only the necessary portion of the retainer portion c. Dice 10 is attached.

The first cam 3 contacts and presses the rear end side of the presser die 9, and its vertical movement causes the cam holder 11
It is now being guided by The second cam 4 abuts against and presses a slope formed downwardly toward the cutting edge of the hook-type die 10.
It is designed to slide backwards. The push-cut punch 5 has a cutting edge plane formed in a substantially L-shape in accordance with the shape of cutting the flange portion b of the sash A placed on the receiving die 8, and also facilitates cutting of the flange portion b. The blade is formed so that the cutting edge is slanted with the corner as the tip. The knock-out bar 6 is used to further flatten the retainer part c cut down with the hook-type die 10, and preferably has an uneven tip surface so as not to contact and press the retainer part that is left in an upright state. The receiving die 8 is formed so that its mounting surface corresponds to the cross-sectional shape of the sash along with the die holder 7, and the sash A can be fitted and placed on the mounting surface. The presser die 9 has a die body shaped like a hawk in order to support only the remaining part of the retainer part c in the upright state, and the hook-type punch 10 passes the retainer part c with the punch 10 and retreats to partially punch the retainer part c. Punch 1 to cut down
It is shaped like a hawk, which is different from 0.

In addition, on the punch plate 1 side, the protrusion dimensions from the punch plate 1 are changed so that the first cam 3, the second cam 4, the push-off punch 5, and the knock-out bar 6 perform their respective functions in this order. is installed. In addition, on the die plate 2 side, the presser die 9 and the hook type punch 10 that slide on the plate are both mounted on a slide base 12.
Moreover, the presser die 9 is moved backward when the pressure of the first cam 3 is released, and the hook-type punch 1
0 is configured to be freely tensionable and biasable by a spring so as to move forward when the pressure of the second cam is released.

The operation of the vehicle sash processing apparatus constructed in this manner will be explained based on FIGS. After that, the punch plate 1 is pressed down using a press device (not shown) or the like. When the punch plate 1 moves downward, the first cam 3 first contacts and presses the presser die 9, causing it to slide forward toward the sash A side. In this forward sliding, the retainer portion left in the upright state of the sash A is supported by the tip of the presser die 9 formed in a hawk shape. Presser die 9
When the retainer is supported, the second cam 4 comes into contact with the hook-type punch 10 and moves backward, and the inverted L-shaped shearing blade of the punch tip 10 moves past the presser die 9. , the part of the retainer part c that is not supported by the presser die 9 is cut down and moved. At the end of the shearing, the push-cut punch 5 comes to partially cut the flange part b of the sash A placed on the receiving die 8, and the knock-out bar 6 also cuts the die holder 7.
By pressing the cut-down retainer part with the hook-type punch 10 in contact with the flat surface of the retainer part, the retainer part can be folded flat.

When this one-step operation is completed, the punch plate 1 is lifted by releasing the pressure, and the presser die 9 and the hook type punch 10 are moved to the first and second cams 3 and 4.
When the contact pressure of the punch plate 1 is released, the punch plate 1 returns to its original position due to the tension bias of the spring, and waits until the next downward movement of the punch plate 1.

Industrial Applicability As described above, according to the vehicle sash processing apparatus according to the present invention, both the cutting and removal of the flange portion and the cutting down of the retainer portion can be performed in a single process operation, resulting in extremely high work efficiency. In addition to eliminating damage to the surface since the sash can be taken in and out in one go, the dimensional relationship between the cut point of the flange part and the cut down part of the retainer part can be made constant, making it easier to attach to the door panel. be able to.
