The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1-Fig. 5, high accuracy rail head hydraulic forging press, the slide block 8 that comprises the combination frame fuselage 1 that constitutes by entablature 1-1, sill 1-2 and four column 1-3, is packed in master cylinder 2 and side cylinder 3 on the entablature, is connected with the side cylinder with master cylinder and be installed in sill on travelling table 7.Upper padding plate 10 and upper slide 11 are equipped with in described slide block 8 bottoms, are shaped on the T-slot that matches with last clamping cylinder piston rod T shape head on the described upper slide, and it is fastening with upper slide 11 and slide block that last 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 on the T-slot that matches with following clamping cylinder piston rod T shape head, and following 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 moulds 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.
Described die arrangement device 6 comprises: mould positional cylinder 6-1, sense switch 6-2 and support 6-3, and described mould positional cylinder is packed in the middle part of travelling table 7, and mould positional cylinder bottom is fixed with support, and sense switch is housed on support.
Operation principle of the present invention is:
See also Fig. 6 a-Fig. 8 b, mould promotes the stroke of cylinder 5-1 and sets by position detector 5-2, when three station moulds 4 are positioned at the press right end position, can carry out first station compacting of rail head workpiece.Whether at this moment, described mould positional cylinder 6-1 is in the state of ejecting, and detect the mould positional cylinder by sense switch 6-2 and eject and put in place.After finishing, mould promotes cylinder and is moved to the left under the control of position detector, and when promoting lower skateboard and mould and being moved to the left second station, by mould positional cylinder 6-1 location, carries out second station compacting of rail head workpiece.Whether after the compacting of this station was finished, the mould positional cylinder was return, and detect the mould positional cylinder by sense switch and return and put in place.When mould promotes cylinder and continues to promote lower skateboard and mould and be moved to the left the 3rd station that position detector sets, carry out the 3rd station compacting of rail head workpiece.After the compacting of the 3rd station was finished, mould promoted cylinder drive lower skateboard and is reset to the first station position, and at this moment, mould positional cylinder 6-1 is in the state of ejecting.The main effect of collision block 5-3, left block 5-4 and right block 5-5 is to promote to play spacing and protective effect when cylinder is in left and right limit position (i.e. first station and the 3rd station) when mould; excess of stroke phenomenon takes place in malfunctioning or maloperation because of position detector to prevent mould to promote cylinder, and then the damage of having avoided the mould thrust unit to cause because of the excess of stroke.
