    Abstract: A butt welding system and a butt welding method of steel plate by which the quality of a product can be ensured. Butting portions of blank members (1,2) to be joined together are butted and a predetermined butting load is applied to the butting portion, wherein the blank members (1,2) are moved relatively in the direction of the welding line thus matching the butting portions. Protrusions and recesses formed on each butting portion of each blank member (1,2) are flattened, whereby linear precision at each butting portion of each blank member (1,2) is enhanced as compared with a case where the butting portions are not matched. Since the gap is reduced extremely at the butting portion, welding is facilitated at the butting portion. Good welding beads are thereby obtained at the butting portion and the quality of a product is ensured.

  • Patent number: 7857295
    Abstract: A clamping mechanism includes a fixing table forming a bracket, a first clamping apparatus, and a second clamping apparatus. The first clamping apparatus includes a sliding member slidably installed on an upper portion of the bracket, and a movable member coupled to the sliding member. The sliding member forms a protrusion, and a first clamping device is installed on the movable member for cooperating with the protrusion of the sliding member to sandwich an upper portion of a workpiece therebetween. The second clamping apparatus includes a sliding block slidably installed on a lower portion of the bracket, and a positioning post slidably installed on the fixing table. The sliding block forms a protrusion, and a second clamping device is installed on the positioning post for cooperating with the protrusion of the sliding block to sandwich a lower portion of the workpiece therebetween.

  • Publication number: 20100320669
    Abstract: A device for welding plastic tubes includes a laterally movable tube holder having tube holding areas and a laterally fixed tube holder having tube holding areas. Each tube holder includes clamping structure for clamping each tube placed in the respective tube holder areas and for creating a fluid free area. A spring mechanism urges the laterally movable tube holder toward the laterally fixed tube holder to maintain the clamp faces flush against each other. A clamp locking mechanism is provided to supplement the action of the spring mechanism by maintaining the clamp faces flush against each other during the loading of the tubes.
