。FIG. 1 is a plan view showing a side member of an automobile frame as a longitudinal product, and FIG. 2 is a front view thereof,
FIG. 3 is a diagram illustrating normally occurring welding distortion and the form of reverse warpage given to cancel the welding distortion. Figure 3 is the first
It is a sectional view taken along the line ■-■ in the figure, and is a diagram showing a state in which two channels constituting the side member are combined. FIG. 4 is a front view of a welding jig which is an embodiment of the present invention, and FIG. 5 is a sectional view taken along the line v-v in FIG. 4. Further, FIG. 6 is a simplified diagram conceptually showing another embodiment of the present invention.

Claims

[Scope of utility model registration request]

(1) A jig for forming a single long product by welding a plurality of long materials along the longitudinal direction, the jig comprising three or more fixing pieces arranged along the longitudinal direction of the long materials. Three or more clamp units including a clamping tool and a movable clamping tool provided opposite each of the fixed clamping tools and working together with each of the fixed clamping tools to sandwich the elongated material from both sides, A welding jig that clamps a long material at three or more locations separated in the longitudinal direction and holds the long material in a reversely warped state to cancel welding distortion, the welding jig supporting at least one of the fixed clamping tools. a movable base that is rotatable in a plane parallel to a moving direction of a movable clamp corresponding to a fixed clamp supported by the base, and the movable base is fixed at a plurality of rotational positions. A welding jig for a long product, characterized in that a fixing device is provided to change the amount of reverse warpage by rotating the movable base.

(2) One of the three or more fixing clamps in the center
two groups of fixed clamps arranged on both sides of the fixed clamp supported on the fixed base, each supported by one movable base;
The welding jig according to claim 1, wherein the movable base is rotatably supported at an end near the fixed base.

(3) At least some of the fixed clamps include:
A separate clamping unit is provided to clamp the long material in a direction substantially perpendicular to the direction in which the long material is held in cooperation with the movable clamping tool, and the separate clamp unit is provided with a channel having a U-shaped cross section. Another channel material having a width narrower than the channel material is fitted into the inside of the material in a state facing each other, and the material is tightened in the width direction to operate with a force sufficient to eliminate the gap in the width direction between the two channel materials. A welding jig according to claim 1 or 2 of the utility model registration claim.
