摘要： PROBLEM TO BE SOLVED: To provide a tool recognizing device capable of checking correction of the kind of tools by checking elements of relatively small number, and shortening the measurement time for checking. SOLUTION: The tool recognizing device comprises a measuring part determining system 4, a measuring machine 1, a measurement control mean 5 and a determining means 7. The measuring means 7 determines correct tools (1), (2), etc., if the result of measurement of each measurement element shows that all the measurement elements are present. The measuring part determining system 4 disassembles the shapes of the tools (1), (2), etc., included in a tool group 11 into shape elements A, B, etc., forming partial shapes. The measurement elements out of the shape elements A, B, etc., are determined for the parts to be measured for each tool. The characteristic shape elements A, B, etc., of the tools (1), (2), etc., are preferential measurement elements. The degree of priority is higher for those having small overlapping number of the shape elements A, B, etc.

摘要： PROBLEM TO BE SOLVED: To provide an inexpensive press machine which is used for blanking, swaging and die forging and is designed to permit the use of a fine guide shaft by diminishing a rotational moment generated in a slide plate so supporting a movable die of the press machine. SOLUTION: Drive shafts 61a and 61b of drive sources 60a and 60b of the press machine form a planar polygon peaking at thrust points (engaging parts) 62a and 62b at which the drive shafts thrust the slide plate 40 at these thrust points. Displacement measuring means 50a and 50b are disposed near these engaging parts, and while the displacement of the engaging parts is measured in mid-way of molding, the drive sources are controlled by control means and the press machine is operated while the planar polygon is maintained horizontally.

摘要： PROBLEM TO BE SOLVED: To provide a punching die manufacturing method and a punching die capable of easily prolonging the service life at a low cost. SOLUTION: Only a die blade part 35 is manufactured by using high grade steel which is hard and has long service life, and since the die blade part 35 is easily integrated with a die body part 31 made of inexpensive general steel with adhesive 39, the service life can be prolonged while suppressing the increase of the total cost. In addition, since the die blade part 35 is integrated with the die body part 31, and machined with the die body part 31 as a reference, the machining accuracy can be ensured. When the die blade part 35 is integrally joined with the die body part 31 with the adhesive 39, the die blade part and the die body part are connected to each other after the mutual positioning by a positioning part 33, and can be positioned easily and correctly.

摘要： PROBLEM TO BE SOLVED: To provide a turret punch press having a chip removing means for removing chips generated in the case of pressing a work and adhered to an upper die. SOLUTION: In this turret punch press for positioning an upper die 9 provided on an upper turret 3 and a lower die 10 provided on a lower turret 4 to a work station 8 by synchronously rotating the upper turret 3 and the lower turret 4, and pressing the work 6 between the upper and lower dies, the chip removing means 13 for removing chips adhered to the upper die 9 is provided in the vicinity of the upper and lower turrets 3 and 4. Even when needle-like chips generated in the additional punching, etc., of the work 6 are stuck to the upper die 9, the chips are automatically removed by the chip removing means 13 when the upper and lower turrets 3 and 4 are rotated, a product is prevented from being damaged by chips, or chips are prevented from biting the work 6 and generation of dents in the product can be prevented. The quality of the product can be improved thereby.
