Description

Limiting device for web plate die assembly tool

Technical Field

The utility model relates to the technical field of limiting devices, in particular to a limiting device for a web plate die assembly tool.

Background

The web finger type beam or the plate beam is connected with the upper flange and the lower flange or the side wall of the vertical plate or the box girder below the T-shaped beam flange, and one side of the section bar, which is welded with the flat steel, the angle steel, the flat steel bulb and the plate, is taken as the web. The main function of the web is to resist shear forces and also to bear part of the bending moment. The method is widely applied to the aspects of the current steel structure manufacture, bridge engineering, ship manufacture, engineering machinery, equipment manufacture and the like.

The web is often manufactured by adopting a die casting mode, wherein a metal die with an upper die and a lower die structure is widely used, alloy liquid is cast into the die through a preset casting hole after the upper die and the lower die are closed, and the upper die and the lower die are separated after full cooling and shaping, so that a metal product is obtained. In general, the lower die is fixed, and the upper die can be lifted freely; the upper die and the lower die are easy to damage due to the fact that the upper die and the lower die are large in collision force when being closed due to the fact that the weight of part of the metal die is heavy, the service life of the die is shortened, and the upper die is required to pass through a section of displacement in the downward movement process, the movement precision of the upper die can be influenced during the period, and when the upper die moves onto the lower die, the phenomenon that the upper die and the lower die are out of fit due to dislocation easily occurs.

The patent document with the application number of 201620706590.4 discloses a limiting device for closing and closing an upper die and a lower die of a metal die, wherein the device increases the descending resistance of the upper die before closing by the arrangement of a limiting sleeve and a limiting spring block, slows down the descending speed of the upper die, controls the accurate closing and closing of the upper die and the lower die by the arrangement of an upper fixed limiting block and a lower fixed limiting block, and prevents the upper die from damaging the die due to larger collision force generated between the rapid closing and closing of the upper die and the lower die under the action of gravity, thereby protecting the die structure and the accurate size of the die; however, the device still adopts the mode that the upper die moves vertically downwards to close with the lower die, and the problem that the upper die and the lower die are not closed due to the dislocation phenomenon of the upper die and the lower die still cannot be avoided.
