Problems solved by technology

The disadvantage is: due to the heavy weight of the heavy-duty workbench (for example, the workbench of a 10,000-ton free forging hydraulic press has a self-weight of 100 tons), to form a continuous oil film on the lower surface of the workbench, the dry oil lubrication station needs to provide a high pressure of 40MPa
Dry friction will cause the table to wear quickly in the thickness direction, and at the same time generate a large amount of iron filings, the press will not continue to work
If the pressure of the dry oil lubrication station continues to increase, the cost will increase geometrically

Embodiment Construction

[0015] The present invention is further described below in conjunction with embodiment and accompanying drawing.

[0016] The embodiment is a heavy-duty floating workbench of a 10,000-ton free forging hydraulic press, which includes a workbench body 2, a lower beam 9, a slide plate 10 and floating rollers. The slide plate is placed on the lower beam 9, and there is no gap between the workbench body 2 and the slide plate. Seam fit, the floating idler includes pin 1, spring 4, wheel 5, bearing 6, shaft 7 and retaining ring 8, the lower part of pin 1 is a channel steel wheel seat, and the center position of the upper plane of the channel steel wheel seat There is a cylindrical pin, and a shaft hole is opened on the two vertical plates of the channel steel wheel seat. The shaft 7 is installed on the two vertical plates of the channel steel wheel seat through the retaining ring 8, and the wheel is installed in the groove of the shaft through the bearing 6. Between the two vertical ...

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 [0001] The invention belongs to the technical field of heavy forging hydraulic presses, in particular to a floating workbench of heavy forging hydraulic presses. Background technique [0002] The workbench of the heavy forging hydraulic press of the prior art and the slide plate below are seamlessly fitted, and the lubrication between the movement pairs depends on the oil film on the lower surface of the workbench. The disadvantage is: due to the heavy weight of the heavy-duty workbench (for example: the workbench of a 10,000-ton free forging hydraulic press has a self-weight of 100 tons), to form a continuous oil film on the lower surface of the workbench, the dry oil lubrication station needs to provide a high pressure of 40MPa. The service life of lubricating elements that work under high pressure for a long time is extremely short. Once the lubricating elements are damaged, dry friction will form between the table and the slide plate. Dry friction will c...
