Abstract
The utility model relates to a large railhead refined forging press which comprises a combo-box type machine body consisting of an upper cross beam, a lower separator and four columns, a main cylinder and a side cylinder which are both arranged on the upper cross beam, and a movable work platform arranged on the lower cross beam. The large railhead refined forging press is characterized in that the main cylinder adopts a sliding block structure with the cylinder and the main cylinder and a steel plate are connected in a welding mode to form the sliding block structure. A plunger is fixed on the upper cross beam and one end of the side cylinder is connected with the sliding block. A workpiece ejection mechanism is fixedly arranged in the upper beam. The large railhead refined forging press has the advantages that the large railhead refined forging press has simplified press structure, strong bias load resisting ability and convenient operation. The two side cylinders adopt two piston hydro-cylinders and therefore the upper cross beam and the sliding block can bear force evenly, have small deformation and good accuracy maintenance, and besides, the sliding block is more stable in operation and suitable for processing of various shapes of parts. Moreover, through the utilization of the workpiece ejection mechanism, the large railhead refined forging press enables the material taking to be convenient, enhances work efficiency and reduces labor intensity of operation staff.
Description
Technical field
The utility model belongs to the forging press technical field, particularly relates to a kind of large-scale rail head finish forge press.
Background technology
At present, being used for track rail head compression molding device mainly is to adopt three beam four-column hydraulic presses.Along with developing rapidly of high-speed railway, more and more to specification, the shape need of track switch, and become increasingly complex.The equipment nominal pressure is big, reliable in structure, easy to operately seem very outstanding.Three traditional beam four-column hydraulic press master cylinder arrangement are that cylinder body is fixed on the entablature, and plunger is fixed on plane on the slide block, drive slide block by plunger and move up and down.Not only make machine construction complicated, take up room greatly, and anti-bias load ability and steering capability are poor; The discontinuity of entablature and slide block, the easy generation are out of shape; Can't reach high-precision processing, therefore waste raw material, cause processing cost high; Also assembling brings great difficulty to machine simultaneously, so the conventional hydraulic machine can't satisfy the hot compression molding technological requirement of large-tonnage, AT rail heel end.
Summary of the invention
The utility model provides a kind of simple and compact for structure, large-scale rail head finish forge press that can guarantee machining accuracy for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Large-scale rail head finish forge press; Comprise the combination frame fuselage that constitutes by entablature, sill and four columns, be packed in master cylinder and side cylinder on the entablature, be installed in the travelling table on the sill; It is characterized in that: said master cylinder adopts band cylinder slide block structure, and said band cylinder slide block structure is to be welded into a whole by Master cylinder body and steel plate, and plunger is fixed on the entablature; Said side cylinder one end is connected with slide block, is fixed with ejecting mechanism under the workpiece in the said sill.
The utility model can also adopt following technical scheme:
Ejecting mechanism comprises the workpiece liftout tank and the workpiece knock-pin that is connected with its top that is installed in the sill under the said workpiece.
Advantage and the good effect that the utlity model has are: this hydraulic press is applicable to the hot compression molding technology of various AT rail heel ends; The hydraulic press master cylinder adopts band cylinder slide block structure; Not only can simplify press structure, the anti-bias load ability is strong, handled easily, both sides cylinder adopt two ram cylinders; This structure can make that entablature and slide block are stressed evenly, distortion is little, is heated, precision stability is good behind the pressurized; More steady during the slide block operation, can adapt to the processing of different shape part.In addition, realize conveniently getting material, enhancing productivity, reduce labor intensity of operating personnel through the workpiece ejecting mechanism in the sill.

The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1; Large-scale rail head finish forge press; Comprise the combination frame fuselage 1 that constitutes by entablature 1-1, sill 1-2 and four column 1-3, pull bar 1-4 and locknut 1-5, on entablature, be fixed with master cylinder 2-1 and side cylinder 3, be installed in installation and moving workbench 5 on the sill.Said master cylinder adopts band cylinder slide block 2 structures, and said band cylinder slide block structure is to be welded into a whole by Master cylinder body and steel plate, and plunger is fixed on the entablature, and said side cylinder 3 one ends are connected with slide block 2-2.On sill 1-2, be provided with travelling table 5, and clamp through Tischarretierungsvorrichtung 7.Be fixed with ejecting mechanism 6 under the workpiece among the said sill 1-2, ejecting mechanism comprises the workpiece liftout tank 6-1 and the workpiece knock-pin 6-2 that is connected with its top that is installed in the sill under the said workpiece.In the forging process, drive the workpiece push rod by the workpiece liftout tank workpiece is ejected.When equipment need overhaul; Slide block 2-2 drives backhaul to topmost by side cylinder 3; Said hydraulic locking apparatus 4 is packed on the pillar, is generally diagonal, and slide block drives backhaul to topmost by side cylinder 3 when equipment need overhaul; And pass through hydraulic locking apparatus 4 with its pinning, prevent in maintenance process, to cause danger.
