The specific embodiment
For further understanding summary of the invention of the present invention, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1-Fig. 5, high-accuracy railhead forging hydraulic machine, comprise by entablature 1-1, sill 1-2 with are connected combination frame fuselage 1 that column 1-3 consists of, be packed in that master cylinder 2 on the entablature is connected with the side cylinder, the slide block 8 that is connected with the side cylinder with master cylinder and the upper travelling table 7 that is installed in sill.Upper padding plate 10 and upper slide 11 are equipped with in described slide block 8 bottoms, are shaped with the T-slot that matches with upper clamping cylinder piston rod T shape head on the described upper slide, and it is fastening with upper slide 11 and slide block that upper clamping cylinder 9 passes upper padding plate 10.Lower bolster 12 and lower skateboard 13 are housed on the travelling table 7, and described lower skateboard is shaped with the T-slot that matches with lower clamping cylinder piston rod T shape head, and lower clamping cylinder 14 passes lower bolster 13 lower skateboard and travelling table are clamped.Wherein between two columns of a side mould thrust unit 5 is installed, is positioned at the travelling table middle part and is provided with die arrangement device 6.The patrix of described three station dies 4 is connected with upper slide, and counterdie is connected with lower skateboard.
Described mould thrust unit 5 comprises: mould promotes cylinder 5-1, position detector 5-2, collision block 5-3, left block 5-4 and right block 5-5, described mould promotes cylinder one end and is connected with lower skateboard 13 1 sides, the other end is fixed between two columns, position detector one end is packed in the column inboard, the other end is connected with lower skateboard, collision block is packed on the lower skateboard, and left block and right block are fixed with travelling table respectively.
