Appl. No.:

9/004685

Inventors:

Steve Shaffer - Hudson OH

Assignee:

Iron Bay - Hudson OH

International Classification:

B23K 3700
B23K 100
B23K 114
B23K 522

US Classification:

228 57

Abstract:

Apparatus and method for setting welding run-off tabs in a coil end joiner which includes a support table having a U-channel therein, the U-channel having an opening through a base portion thereof, a left hold down clamp and a right hold down clamp positioned to either side of the U-channel over the support table, a first angled member having an actuator which provides horizontal movement of the first angled member, the first angled member extending upwardly through the opening in the base portion of the U-channel and contacting a corresponding second angled member such that horizontal movement of the first angled member results in vertical movement of the top surface of the second angled member which is parallel to the top surface of the support table. A rear welding run-off tab holder member having a U-channel therein is positioned over the second angled member and includes a rear welding run-off tab clamp which is positioned at a rear end thereof. A forward welding run-off tab holder and copper chill bar member includes a forward welding run-off tab clamp on a forward end thereof.

Abstract:

An apparatus and method for leveling the clamping surface to obtain proper heat sink for narrow strips in a coil end joiner which includes a coil material support table and a retaining plate which is positioned against the upper surface of the coil material to be joined by, for example, one or more air cylinders. A weld clamp leveler is also provided which is adjustable to provide a preselected offset between the coil material support table and the retaining plate in a forward portion of the coil material support table. The weld clamp leveler is preferably used when relatively narrow coil material is being joined to preclude tilting of the retaining plate relative to the coil material support table and the coil material being joined and is preferably adjusted to provide approximately the same offset between the coil end support table and the retaining plate as the thickness of the coil material being joined. On the other hand, when coil material which is sufficiently wide to preclude tilting of the retaining plate is being joined, the weld clamp leveler is disengaged and does not interfere with the coil end arc welding operation.
