Description

  The present invention relates to a cutting device for cutting a sash.

  A schematic configuration example of a conventional vehicle door will be described with reference to FIG. Here, FIG. 7 is a configuration explanatory view of the main part of the left front door of the sedan type passenger car as viewed from outside the passenger compartment. As shown in FIG. 7, a door frame 2 is provided on the upper part of a door (sash door) 1, and the glass 3 is moved up and down by being guided by a glass run attached thereto. The door 1 is attached to the vehicle body by a hinge so that the left end portion in FIG. 7 can be opened and closed. In addition, a weather strip is attached to the door 1 in order to seal the inside of the vehicle. The door frame 2 is composed of an upper sash (roof portion) 4 and a side sash (pillar portion) 5. Fitted and welded.

  The cross-sectional shapes of the upper sash 4 and the side sash 5 will be described with reference to FIG. Since the upper sash 4 and the side sash 5 have substantially the same cross-sectional shape, the upper sash 4 will be described. As shown in the figure, the upper sash 4 is manufactured by roll-molding a plate material, and the cross section of the upper sash 4 is a design surface 4a exposed to the outside, and the design surface 4a on the back side of the design surface 4a. It consists of a leg portion 4d that intersects in a T-shape and is fixed by welding, and a closed bag portion 4c that is connected to the leg portion 4d. A weather strip holding part 4e and a glass run holding part 4b are formed back to back via the leg part 4d.

  Next, the joint portion J will be described. The upper sash 4 and the side sash 5 manufactured by roll forming and formed into a predetermined shape form a cut surface of the joint portion J by a cutting device. The design surface 4a has different widths between the upper sash 4 and the side sash 5, whereas the leg portion 4d and the closed bag portion 4c have the same shape. Therefore, the cut surface of the sash at the joint portion J is as follows. The front side and the back side are cut at different angles with respect to the longitudinal direction of the sash.

The upper sash 4 and the side sash 5 are abutted and welded after the cut surface of the joint surface J is formed by a cutting device. Usually, TIG welding is used for the front side of the sash, that is, the portions of the design surfaces 4a and 5a, and TIG welding or MIG welding is used for the back side portion (inner side portion) (see, for example, Patent Document 1).
