Description
Technical field
The present invention relates to a kind of hydraulic press that is used for the sheet metal smoothing, especially a kind of moving gantry type numerical control slab smoothing hydraulic press.
Background technology
Sheet material, especially slab at car industry, the medium-and-large-sized weldment of shipbuilding industry (slab) needed leveling before combination at present, can reduce the cutting output of machined face like this, saved raw material.Its bottom, gantry roller of the moving gantry type smoothing hydraulic press of existing little tonnage, little table top is the suspended wall structure, the flexible distortion of stress official post roller shaft, cause gantry and table slide gap to increase, thereby former smoothing hydraulic press is equipped with 4 lift cylinders in bottom, gantry, rising during work makes gantry contact fully with table slide, eliminate the vibratory impulse that big gap produces with this, therefore make structure comparatively complicated; The up walking dolly of walking to have master cylinder and drift is by chain drive at gantry in addition, so displacement accuracy is relatively poor, does not often reach smoothing workpiece purpose accurately.
Summary of the invention
The present invention provides the moving gantry type numerical control slab smoothing that a kind of structure is simpler, precision is higher hydraulic press for solving the technical problem that exists in the known technology.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
A kind of moving gantry type numerical control slab smoothing hydraulic press, have the stationary work-table that lower guideway and center have the jack-up cylinder by both sides, across on stationary work-table along gantry that its guide rail moves, be installed in four the band tooth rollers of bottom, gantry rolling on the stationary work-table lower guideway, be installed in bottom, gantry and band tooth roller pinion in mesh and drive motors thereof, be installed in the dolly and the drive unit thereof of laterally walking above gantry, be vertically mounted on the master cylinder that has slide block and drift on the walking dolly and the guide pillar of both sides thereof, and be installed on the dolly when stopping locking cylinder composition with gantry locking, the outside of described gantry bottom inside wall also is fixed with support plate, described band tooth roller is installed between gantry bottom inside wall and support plate, in the axis hole of band tooth roller axle and bearing are installed, its both ends of the surface are equipped with bearing cap, the positioning adapter of bearing is installed on the axle, described pinion and drive motors thereof are installed on the support plate; The drive unit of described walking dolly is that mother lead screw is installed below walking dolly, is horizontally installed with leading screw in the mother lead screw, and the leading screw two ends are equipped with the support that is fixed on above gantry, also is equipped with on the end support to drive the variable-frequency motor that leading screw rotates.
The present invention can also adopt following technical measures:
The both sides of described master cylinder also add two the side cylinders parallel with master cylinder, and the cylinder body of both sides cylinder is hinged on the master cylinder body, and the piston end of both sides cylinder is hinged on the slide block of master cylinder.
The brush of promising workbench lower guideway dedusting also is installed on the support plate of bottom, described gantry band tooth roller.
Advantage and good effect that the present invention has are: because the band tooth roller shaft of mobile gantry is installed on gantry bottom inside wall and the support plate, make band tooth roller shaft improve bearing capacity greatly and eliminated the flexural deformation of being with the tooth roller shaft, thereby can guarantee reasonable clearance between gantry and table slide, four mobile gantry lift cylinders have been saved, simplify the structure, reduced manufacturing cost; Owing on walking dolly, adopt the drive unit of mother lead screw, leading screw and variable-frequency motor, make walking dolly horizontal displacement accuracy that improved when mobile on gantry; Make the slide block operation more steady owing to add the both sides cylinder in the master cylinder both sides, running precision improves greatly; Owing on the support plate of gantry bottom, table slide dedusting brush has been installed, avoided by the oxide skin that comes off on the sheet material of leveling and dirt damage and wear to table slide; The present invention also has compact conformation in addition, and work top is low, and is easy to operate, improves the advantage in service life.
