Abstract
A heavy-duty floating worktable comprises a worktable body, a lower beam, a slide plate and a floating roller. The floating roller consists of a pin, a spring, a wheel, bearings and a shaft. A channel-steel wheel holder is arranged on the lower portion of the pin, a cylindrical pin is arranged at the center of the upper plane of the channel-steel wheel holder, the shaft is mounted on the channel-steel wheel holder, and the wheel is mounted on the shaft. Circular stepped holes are uniformly formed on the left and the right of each of the front and the back of the lower surface of the worktable body, the floating roller is mounted in the stepped holes of the lower surface of the worktable body, the spring is sleeved on the cylindrical pin between the upper plane of the channel-steel wheel holder of the pin and the bottom surface of the first stepped hole, and the wheel is tangent with the surface of the lower beam. The heavy-duty floating worktable has the advantages of compact structure and maintenance convenience. The floating roller balances 80% of dead weight of the worktable and reduces pressure for grease to flow into an oil groove on the slide plate, and thus service lives of lubricating elements are prolonged and service and maintenance cost are reduced. The residual weight of the worktable is enough to guarantee seamless fit of the worktable body and the slide plate.
Description
Technical field
The invention belongs to heavy hydraulic forging press technical field, relate in particular to the floating type workbench of heavy hydraulic forging press.
Background technology
The workbench of the heavy hydraulic forging press of prior art and the slide plate below it are seamless applying, the lubricated oil film by workbench lower surface between kinematic pair.Its deficiency is: for example, due to heavy bench own wt very large (: the workbench deadweight of 10000 tons of open die forging hydraulic presses is 100 tons), form continuous oil film at workbench lower surface, dry oil lubrication station need provide the high pressure of 40MPa.The life-span of long-time lubricating element of under high pressure working is all extremely of short duration, once lubricating element corrupted will form the situation of dry friction between workbench and slide plate.Dry friction meeting causes workbench Fast Wearing on thickness direction, produces a large amount of iron filings simultaneously, and press cannot work on.The dry oil lubrication station pressure that raises as continued, cost will become how much radixes to rise.
Summary of the invention
The workbench object of heavy hydraulic forging press is to provide a kind of floating type workbench of heavy hydraulic forging press, overcomes the deficiencies in the prior art.
Technical scheme of the present invention is: the floating type workbench of a kind of heavy type, comprise workbench body, sill and slide plate, slide plate is placed on crossbeam, below workbench body and seamless applying between slide plate, it is characterized in that the floating type workbench of described heavy type also comprises floating idler roller, described floating idler roller comprises latch, spring, wheel, bearing and axle, described latch bottom is a channel steel type Wheel housings, the center position of the upper plane of channel steel type Wheel housings is provided with a straight pin, on two risers of channel steel type Wheel housings, have axis hole, axle is arranged on two risers of channel steel type Wheel housings, wheel is arranged on by bearing between two risers of channel steel type Wheel housings of axle, spring housing is contained on the straight pin of upper plane of channel steel type Wheel housings of latch, the place, the left and right sides on every limit of the front and rear side below described workbench body, position in slide plate outside evenly has to individual round shoulder hole, the internal diameter in shoulder hole the first hole, rank is identical with the external diameter of plane on the channel steel type Wheel housings of latch, shoulder hole second-order hole is positioned at the center of the first bottom surface, hole, rank, the internal diameter in second-order hole is identical with the external diameter of the straight pin of latch, floating idler roller is arranged in the shoulder hole below workbench body, the straight pin of floating idler roller latch is placed in shoulder hole second-order hole, matched in clearance between the internal diameter in the external diameter of straight pin and second-order hole, the channel steel type Wheel housings of latch is placed in shoulder hole the first hole, rank, matched in clearance between the external diameter of plane and the internal diameter in shoulder hole the first hole, rank on channel steel type Wheel housings, spring is placed on the channel steel type Wheel housings of latch between plane and the first bottom surface, hole, rank, wheel and sill surface are tangent.
The floating type workbench of a kind of heavy type of the present invention, is characterized in that being capable of carrying a load of of described spring is less than 90% this body weight of workbench, 80% this body weight of workbench being more than or equal to.
Operation principle of the present invention is:, spring is the effect lower compression from gravity at workbench body, and spring-compressed produces power upwards, and this dynamic balance is fallen the gravity of workbench body 80%, and all the other gravity of 20% are born by the slide plate below workbench body.Make the face pressure above slide plate lower 80%, thereby reduced drier oil, enter the required pressure of slide plate finishing bathtray.The invention has the beneficial effects as follows:
1, floating idler roller is installed on workbench inside, and compact conformation is easy to maintenance.
2, a floating idler roller balance deadweight of workbench 80%, the remaining weight of workbench enough guarantees that workbench and slide plate below continue to keep good seamless applying, meet the needs of Forging Technology.
3, device is applicable to heavy hammered work platform, and the larger effect of workbench deadweight is more obvious.
4, device makes the face pressure above slide plate lower 80%, drier oil enters the required pressure of slide plate finishing bathtray to be reduced significantly, oil film below workbench body is able to continuously, avoided the dry friction between workbench body and slide plate, the wearing and tearing of workbench body and slide plate have been reduced greatly, the service life of having improved workpiece.Lower the pressure of lubricating system simultaneously, improved the service life of lubricating element, reduced the operation and maintenance cost of press.
