Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for rivet-connection or punching-out, particularly, precisely performing the rivet-connecting or the punching-out process. SOLUTION: In the method for the rivet-connection of the punching-out by using the rivet-connection or the punching-out apparatus, with which a pick-up device 4 and a male type die guided with the pick-up device, are provided and both can be shifted to a female type die or a working material, and the female type die is connected with this apparatus through a reaction structural body 9, a relative shifting between the pick-up device 4 and the reaction structural body 9 is measured with a first sensor 1 and a relative shifting between the reaction structural body and the male type die, is measured with a second sensor 2, and the depth of the rivet-connection or the punching-out, is adjusted with two measured values. A related device can quickly and accurately detect the working material, or can perform the precise punching-out or the rivet- connection at a constant prescribed depth, regardless of the change of the quality of a material or the other parameter causing the deformation of the reaction structural body 9 during punching-out process.

Abstract: PROBLEM TO BE SOLVED: To provide a separation device for connecting with a rotary magazine. SOLUTION: This separation device conveys a rivet 3 through a conveyor duct 6 formed by three boundary faces. The first boundary face is a substrate 5, the second boundary face is a right side guide member 1, and the third boundary face is a left side guide member 2. At least one of the guide members is designed and arranged so as to be excited and vibrate to avoid blocking of the rivet 3 in the conveyor duct 6.

Abstract: PROBLEM TO BE SOLVED: To provide a method to a remove a pierced rivet mounted to a tubular and axis symmetrical object to be worked and an apparatus therefor. SOLUTION: A punched piece left in a pierced rivet when mounting the pierced rivet is removed by a tool, further, a mandrel with thread is screwed into the pieced rivet while forming a substantially continuous another screw thread. Successively the mandrel is pulled against a pressing force of a receiving base placed on the tool, the pieced rivet is pulled out from the work by the mandrel with the thread.

Abstract: PROBLEM TO BE SOLVED: To provide a method for mounting a fastener with a screw on a work piece having a connecting part formed of plural connecting members. SOLUTION: This method comprises the steps of heating the connecting part in a region to be fastened; forming a hole at least on one of connecting members by pressing a fastener with a screw in the connecting part; and making the fastener with the screw screw-engaged with a work piece by forming a screw thread on the connecting part by rotating the fastener with the screw in the hole. A tool to carry out this method is also provided.

Abstract: PROBLEM TO BE SOLVED: To simplify installing work by performing installation of a spiral coil insert and removal of a core by one work. SOLUTION: This power installing tool includes a tubular body having a bore 16 extending in the axial direction, a mandrel 20 coaxially arranged in the bore 16 of this tubular body, a punch coaxially arranged in the bore 16 of the mandrel 20, a motor 32 for rotating the mandrel 20 and an air cylinder 30 for imparting axial directional force to the punch. The mandrel can move to a position for engaging with a spiral coil insert and a position for installing the spiral coil insert in the selected depth in a female screw cut hole existing in a workpiece from a position retracted from the spiral coil insert. The punch slides in the axial direction in the bore 16 of the mandrel 20 for removing a core from the spiral coil insert as soon as the spiral coil insert is installed in the female screw cut hole.

Abstract: PROBLEM TO BE SOLVED: To provide a device for tightening two-parts fastener which is easy in assembly, small in the number of parts, and relatively lightweight. SOLUTION: In order to tighten a two-parts fastener where a first part 7 must be pulled and a second part 6 must be held for tightening, a blind rivet in particular, the device comprises a housing 1, a feed device 9 on the housing 1 to feed the fastener 8 into the housing 1 through an orifice 12 in the housing 1, and a receiving surface 3 having a gripper 5 at an open end of a pulling parts 4 in a cooperation with a pulling piston 13 which can hold the second part 6 in the tightening process, pull the first part 7 in the tightening process, and is movable in the longitudinal direction along the axis of the housing 1 by a working unit in a first chamber 14.

Abstract: PROBLEM TO BE SOLVED: To further develop an existing stud welding equipment to simplify a structural assembly of a stud welding equipment. SOLUTION: A stud welding equipment is composed of an adjustment member 3 movable back and forth in the axial direction, a stud holder 2 connected with the adjustment member 3 so that the motion of the adjustment holder 3 is transmitted to the holder 2, a hollow body located and movable in the axial direction in a gap 13 between a magnetizable core 8 connected with the adjustment member 3 and a magnetizable casing 10, a driving unit 4 having a coil 15 which is rigidly mounted on the hollow body and connectable with a power supply, a compression spring 19 which actuates the adjustment member 3 and pushes the adjustment member 3 to an end position decided by a buffer 23. The core 8 has a recessed part 45 extending from the front end on the side of the adjustment member 3 as long as at least a part of the length in the axial direction of the core 8. At least a part of the compression spring 19 is inserted into the recessed part 45 and the recessed part 45 is coaxial with the adjustment member 3.

Abstract: PROBLEM TO BE SOLVED: To produce reliable electrical continuity by using a swaged nut/stud structure for electrical connection or grounding without needing the step to arrange an additional cap and the initial assembly step of rotating. SOLUTION: A stud type electrical connection structure 21 has a stud 51 having a patterned outer face (thread face) and a nut 53 mounted to the stud by swaging/pressing in the radial direction. Mounting of the nut 53 to the stud 51 produces electrical conductivity path between a mounted conductivity member 55 and a panel 33.

Abstract: PROBLEM TO BE SOLVED: To make a quick change, cleaning and maintenance possible by arrang ing a recessed part to a holding block slidably accommodated in a housing, setting the recessed part to a rivet receiving position when the block is at a first position and sliding the block so that the recessed part is connected to a pressurized gas source and a supply tube when the block is at a second position. SOLUTION: A holding block 28 slidably accommodated in a relief housing 170 is slided to a first position and receives a rivet R sent in a rivet accommodation groove 172 from a truck 24. The holding block 28 is slided to a second position, the rivet accommodation groove 172 is aligned to a position of a rivet supply tube mounted to a run away stop guide tube 206. The rivet R is sent into a rivet supply tube by a pressurized air. When conducting a change of a different rivet R or cleaning, maintenance, the work is done by loosing a butterfly nut 202 and removing an upper plate 190.

Abstract: PROBLEM TO BE SOLVED: To speed up a charging capacity by arranging a piston in a housing, mounting a supply arm to an end part of a piston rod, engaging a cam sleeve arranged in the housing and a cam arranged to the piston and rotating the piston rod in following reciprocation of the piston. SOLUTION: A rod 72 is connected to a piston reciprocating in a main body tube 70 to support a supply arm 74. A cam groove 92 arranged to the main body tube 70 is engaged to a cam follow member 88. When driving the piston 76 in an arrow mark B direction, the rod 72 is rotated, the supply arm 74 is rotated to a position on the same straight line with a tension adopter and a nose part of the jaw case. A rivet R transferred by a rivet transfer tube 39 is blown to the nose part by a pneumatic pressure and is held by vacuum.
