摘要： PURPOSE:To better the fitness of a cap by forming an intermediate annular projection by driving a slightly larger diameter punch into the cap inserting hole of the nut main body forming the inner and outer with a cold forging to eliminate the cutting of a cap inserting hole. CONSTITUTION:The hexagonal outer peripheral part of the billet 10 of a nut main body and a cap inserting hole 12 are formed with cold forging. An intermediate annular locking projection 13 is formed by driving the punch 3 which is slightly larger diameter D than the inner diameter d of the inserting hole 12 thereinto. A screw prepared hole 11 is punched thereafter to perform a threading 15. No cutting is performed for forming the locking projection 13 of the inserting hole 12, so the manhour is reduced, and with excellent mass productivity a remarkably cost reduction is realized. Owing to the face of the inserting part 12 being smooth, there is not breakdown of the fitting part 23 of the cap 20 and the fitness thereof becomes better.

摘要： PURPOSE:To obtain an annular member which is capable of ideal fitting at all times even if an error exists in the inside diameter of a cylindrical case, by constituting so that a part of a ring of an annular member provided with a burring on the inside circumferential edge of the annular outside circumferential part lacks discontinuously. CONSTITUTION:A work B obtained by working cylindrically a strip-like work A by means of roll forming, etc. is placed on a base 12. In this case, there is a step difference between a circumference supporting member 14 and the base 12, therefore, as for the work B, its outside circumferential face is supported by the member 14. Subsequently, when a ram 19 is lowered, the lower end face of a reserve bend die 21 is made to press-conact with the member 14, depresses it, an engaging face 24 is engaged with the work B, and a tapered work C is formed. Subsequently, a bend die 25 is made to press- contact with the work C, depresses the base 12 and presses by piching the work together with the base 12. In this case, the work is lowered together with the base 12 and the die 25, therefore, the circumferential edge part in the work interfaces with a bend punch 11, is bent upwards and is subjected to burring F work. Thereafter, when the ram 19 is lifted, the base 12 also is lifted by a spring 13, therefore, a work D is lifted up, is dropped down onto the base 12 from the lifting member such as the die 21, etc., and an annular member R is obtained.

摘要： PROBLEM TO BE SOLVED: To realize a welding robot which does not need re-teaching work for maintaining the welding quality. SOLUTION: By rotating the position of an end-point K[1] through an angle Θ=α-θ, welding line L on a workpiece is physically conformed to an inclined angle α designated by an angle of θ with horizontal plane. When rotating axis vector(ν) generated by the rotating motion of the above angle Θ is expressed in the formula v=(λ, μ, ν), the vector(ν) is given by the formula v= k×Va/|k×Va|(wherein, (k) shows a unit vector of a positive z-axial direction (vertically upright) and Va indicates a vector for a progress direction of welding motion on welding line L). Thus, by changing the angle θ to inclined angle αdesignated, an angle with horizontal plane of the welding line is automatically optimized and most fitted. This automates reset and re-teaching work for a start point or a end point on the welding line in order to maintain welding quality, and an angle between work and torch can simply be set at the most suitable or fittest angle in a short time.

摘要： PROBLEM TO BE SOLVED: To reduce the error in the expansion and contraction of arms when an intallation environmental temperature changes and to ensure the relative positioning accuracy in the co-operating work to improve the machining quality by vertically three-dimensionally arranging a plurality of robots on a vertical surface of a common column base, grasping a tool by one of the robots and grasping a work by the other robot. SOLUTION: A lower six-axial work grasping robot 3 has the degree of freedom for the movement and posture in a three-dimensional space of a work, and an upper welding robot 2 has the degree of freedom for the movement in the three-dimensional space in a state that a posture of a welding torch T is constantly fixed in the vertical direction for welding the work. An arm of the welding robot 2 and an arm of the work grasping robot 3 are mounted on one surface of a common column base 1 in one movable region, so that both arms are expanded and contracted in the same direction and compensate to one another when an installation environmental temperature changes in the co-operating work, whereby the error in the expansion and contraction of arms is reduced, and the relative positioning accuracy in the co-operating work can be ensured.
