Abstract

PURPOSE:To provide a string-form weather strip partially-notching device which is designed to notch all containing a bridge through a single device, eliminate a need for skillful arts, and sharply reduce the number of processes. CONSTITUTION:A weather strip partially-notching device is degsigned to perform cookie cut in a state that a part is left uncut so that a part of a string-form weather strip 10 is notched and connected to molding part. The string-form weather strip partially-notching device comprises a main recessed blade 20 by which a weather strip is received by the back thereof for cutting, a work support 30 arranged in front of the lower part of the main recessed blade 20 and vertically moved in a state to place the weather strip 10 thereon, a main protrusion blade 41 which is pressed against the weather strip received by the main recessed blade 20 and placed on the work support 30 and served to notch an upper part in a state that a necessary part is left uncut, an auxiliary protrusion blade 42 integrally mounted on this side of the lower part of the main protrusion blade 41, and an auxiliary recessed blade 25 to cut off a part of a bridge, left uncut by the main protrusion blade 41, by pulling back the auxiliary protrusion blade 42.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a partial cutout of a string-like weatherstrip, in which a part of an extruded string-like weatherstrip is cut out and a cookie is cut to leave a part of a cross section for connection with a molding part. It relates to the device.

[0002]

2. Description of the Related Art A description will be given with reference to FIGS. Conventionally, in order to cut a part of the string-like weather strip 10 and connect it to the molding part, a part thereof (a part of the base part 11 and the lip 12 following it) is left as shown in FIG. Just cut the cookies as follows. That is, first, the weather strip 10 placed on the work support 80 is first placed on the convex blade 90 with the concave blade 70 as the back.
Is pressed (FIG. 2) and the upper portion is cut out to a predetermined length, leaving the required lower section (FIG. 3). Then, a part of the bridge 13 on the lip side is left uncut. The remaining bridge 1
A part of 3 is first cut off from the left and right end portions with the left and right remaining portions by using the burr-picking scissors 91, and then cut along the root thereof in the longitudinal direction from the lip 12 so as to cut it (FIG. 4).

However, the notch is formed by the concave blade 70,
The step of cutting out using the work support 80 and the convex blade 90 and the step of cutting off the remaining bridge 13 with scissors are separated into two steps, and a skillful technique is required to cut out the bridge 13 with good appearance, etc. However, there is a problem that it is still unsatisfactory in terms of man-hours and quality.

[0004]

The problem to be solved is that the above-mentioned weatherstrip notch device does not have a function of cutting out the remaining portion of the bridge and is unsatisfactory in terms of man-hours and quality. .

[0005]

Means for Solving the Problems An explanation will be given with reference to FIGS. 1 and 5 to 8. The present invention cuts out a portion of the extruded string-like weatherstrip 10 and forms a portion of the base portion 11 and subsequent lip 12 to connect with the molding portion.
Is a partial cutout device for cutting a cookie while leaving a part of the main concave blade, and a main concave blade 20 for receiving and cutting the weather strip 10 at its rear surface, provided on the lower front of the main concave blade 20 and mounting the weather strip 10. Of the main convex blade 41 and the main convex blade 41 which is notched at the upper portion to leave a necessary portion by pressing the work support 30 which moves up and down by the main concave blade 20 and pressing it against the weather strip placed on the work support 30. The sub-convex blade 42 integrally provided on the front side of the lower part, the sub-concave blade 25 for cutting off a part of the bridge 13 left uncut by the main convex blade 41 by holding down the front lower surface of the weather strip and pulling back the sub-convex blade 42. Is equipped with.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS To explain an embodiment, a portion of an extruded cord-like weatherstrip 10 is cut out and a part of a base portion 11 and a lip 12 following the portion are formed as shown in FIG. The notch device for cookie cutting, except for a part, is configured as follows. Ie 2
Reference numeral 0 denotes a main concave blade that receives the rear surface of the weather strip 10, and reference numeral 30 denotes a work support that moves the weather strip 10 up and down and is provided in front of a lower portion of the main concave blade 20. Reference numeral 31 is a cylinder for moving the work support 30 up and down, 40 is a convex blade provided in front of the main concave blade 20, and is composed of a main convex blade 41 and a sub-convex blade 42. Press it against the weather strip 10
It is to be received by the main concave blade 20, and the upper portion is notched while leaving a necessary portion. The sub convex blade 42 is integrally provided on the lower front side of the main convex blade 41. Reference numeral 25 denotes a sub-concave blade which presses the lower front surface of the weather strip 10 and pulls back the sub-convex blade 42 to cut off a part of the bridge 13 left uncut by the main convex blade 41. Others 51,5
Reference numeral 2 is a cylinder for driving a pair of convex blades 40, which are head-side butted and connected by bolts, the strokes of which are respectively set to X mm and Y mm, and are controlled separately. Several strokes for the blade 40 can be selected. All the blades were attached to the steel die set.

The operation will be described. First, by combining both cylinders 51 and 52, the convex blade 40 is moved to (X + Y) m.
The weather strip 10 is cut out by the main concave blade 20 after making m strokes (FIG. 6). Next, the convex blade 40 is pulled back by X mm only by the first cylinder 51 (FIG. 7), the work supporting cylinder 31 is operated, and the bridge 13 left uncut by the main concave blade 20 is divided into the sub convex blade 42 and the sub concave blade 25. Sandwich it (Fig. 8). Then, the second cylinder 52 is pulled back by Ymm, and the bridge 13 left uncut is cut (FIG. 9).

[0008]

Since the present invention is constructed as described above,
Although the equipment cost will be slightly increased, not only all the equipment including the bridge can be cut out by one equipment, no skilled technique is required, the man-hours can be greatly reduced, and the appearance can be improved.
