摘要： PURPOSE:To realize titled oxidation prevention without reducing the work efficiency, by providing external and internal oxidation preventing devices which are adjacent to a weld zone between external and internal electrode rolls and blow out an inert gas along a weld zone advancing path of a weld can barrel of its downstream. CONSTITUTION:An inert gas blown out of a lower opening part 14C2 of an external oxidation preventing device 7 covers the outside face of a weld point 9 and its adjacent weld zone 3a, and the inert gas blown out of a small hole covers the outside face of the weld zone 3a existing in a downstream a little from the weld point 9 and cuts off air completely. Also, leakage of the inert gas is prevented by a seal member 17 provided between a side wall part 15 being adjacent to the tip part of a leading path 14 for leading the inert gas and the circumferential edge part of an external electrode roll 1. An internal oxidation preventing device 8 is firmly fixed with a bolt 39 to an end part 6a of a mandrel 6 of a downstream of an internal electrode roll 2, and has the same structure and operation effect as the device 7.

摘要： PURPOSE:To remove coating film only from the surface of lapped edge and to minimize the area of exposed iron in resistance welding of lapped edge of a blank of tin free steel by bending the edge along the boundary line and removing the chromium coating film. CONSTITUTION:The edge 17 of a blank 16 of tin free steel is bent in two steps to form a step 18. It is then so formed that the upper face 17a1 of the right side edge 17a in the figure which is to become a lapped part is positioned nearly parallel to the upper face 16a and slightly higher than the face, and the lower face 17a2 of the left side edge 17a in the figure is positioned nearly parallel to the lower face 16b and slightly higher than the face. The chrominum coating film 5 on the faces 17a1, 17a2 is removed by a rotary removing tool 9 having nearly horizontal axial line while carrying the blank 16 in the direction of the arrow, and an exposed part 10 of iron is formed. In this case, even if shaking of rotation occurs in the tool 9, proceeding of the part 10 to the part 18 or inside thereof crossing the boundary 21 between parts 17a, 18 does not take place.

摘要： PURPOSE:To gather cylindrical cans, conveyed in a multirow crowded condition, at a high speed and supply them to a work device without generating a jam. CONSTITUTION:Cylindrical cans, fed by a plurality of rows, are received to an inlet turret 12a in each row, transfer-collected to a single gathering turret 10 through an intermediate turret 11a and supplied to a work device from the gathering turret. In this way, the cylindrical can, even when it has an edge part, can be supplied remarkably at a high speed as compared with in the past by eliminating interference with each other.

摘要： PURPOSE:To form a mush-seam weld zone having stable quality resulted from the lessened fluctuation in the pressing force near a slight gap part provided between the lap parts of the side faces of a can body which is fed while having slight gap by using a fluid pressure and spring to a pressing device which welds said lap parts under pressure with a pair of opposed electrode rolls. CONSTITUTION:When a lap part 6a of the 1st forming body for a can body is subjected to mush-seam welding by electrode rolls 1, 2 and a weld zone 6b is formed, the pressing force exerted, via a spindle 12, on the outside roll 2 is only the pressing force excerted by the air in an air chamber 15. The roll 2 descends quickly right after the welding of the 1st forming body for the can body and at the moment, when the gap part 7 between said body and the 2nd forming body for the can body that follows the 1st body arrived at between the electrodes 1, 2. A piston 10 is unable to follow up the fast descending and the deviation force by a pressing spring 13 acts on the outside roll.

摘要： PURPOSE:To prevent the formation of oxide films and prevent the can drum material metal based on the stripping of oxide films from exposing by welding the part to be welded while sticking liquid thereon to shut it off from air at the time of welding the side seam part of three-piece pipes. CONSTITUTION:The overlap part beta1 of a metal plate beta curved to a cylindrical shape is passed at a high speed in the direction of the arrow T in upper, lower electrode rollers (a), (b), while forming the weld point WP and the side seam part alpha1 of the can barrel alpha is electric resistance welded. At this time, the water L added with a surfactant is sprayed to the inside and outside of the overlap part beta1 during passing the weld point WP and just before or after the same, whereby it is stuck on said part. The air in the overlap part is expelled and lap seam welding is performed in the state that said part is held shut off from air. After the passage through the electrode rollers (a), (b) in succession, the side seam part alpha1 formed is cooled by the water remained and stuck on the inside and outside surfaces of said part, whereby the oxidation of the metal plate is prevented. Hence, the exposure of the metal material surface owing to the peeling of the oxide films of the coating thereon is prevented.

摘要： PROBLEM TO BE SOLVED: To provide a reversing and conveying apparatus capable of reversing and delivering/receiving an article exactly and stably even between turrets of which the diameters and peripheral speeds are different from each other. SOLUTION: A gripper shaft 27 is mounted on an oscillating frame oscillatably fitted on a transfer turret 4 so as to rotate and displace in the axial direction. The gripper shaft is made to perform combined movement of oscillating movement of a horizontal surface, rotational movement around the gripper shaft, and straight movement in gripper shaft direction together with the rotation of the transfer turret, thus performing simultaneous reversion and pitch transformation of the articles between the turrets of which the peripheral speeds are different.

摘要： PROBLEM TO BE SOLVED: To obtain a gripper unit for space conservation by a size reduction with simple structure, simple assembling and regulation, excellent durability and stability. SOLUTION: The gripper unit comprises a pair of forks having gripping parts 2 and openably secured to a fixed pin 6 with respect to a fixed frame 5. In this case, magnets 15 to 15 are fixed to opposite side ends of the forks to the gripping parts. Magnets 16 to 16 are disposed oppositely to magnets of the frame. These magnets are disposed so that magnetic forces are operated in a direction for always closing the pair of forks and closing force and gripping force of the forks are obtained only by the magnetic forces. Groove-like recesses are formed along a circumferential direction on circular arc-like gripping surfaces. Flanges bent concentrically with the gripping surfaces of the gripping parts are formed at the sides of the parts of the forks, and hence the hollow member can be more rigidly gripped.
