Abstract

The utility model discloses a hydraulic die cushion for hydraulic press, including the backing plate, the backing plate below is connected with elevator push rod, the backing plate be three layer construction, by last EVA protective layer, ferro -aluminum composite bed and the steel deck of being in proper order under to. The utility model discloses the backing plate has adopted three layer construction for more firm of backing plate is difficult for receiving pressure and warp, in addition, still is equipped with elevator push rod to support, and more firm has prolonged life.

Description

A kind of hydraulic press hydraulic die cushion
Technical field
The utility model belongs to hydraulic press field, relates to a kind of hydraulic press hydraulic die cushion.
Background technology
In prior art, backing plate is placed on support, and be hollow design in the middle of support, backing plate centre position does not just have supporter, when machine runs, lifter plate presses down, constantly apply pressure to backing plate, the centre of such backing plate is just very easily out of shape, thus causes the service life of backing plate very short, need often to change, lose time and resource.
Utility model content
The purpose of this utility model is to provide a kind of long service life, not yielding, more firmly hydraulic press hydraulic die cushion.
The utility model is for solving the problems of the technologies described above by the following technical solutions: a kind of hydraulic press hydraulic die cushion, includes backing plate, is connected with lifting top rod below described backing plate; Described backing plate is three-decker, is followed successively by EVA protective layer, ferro-aluminum composite bed and steel plate layer from top to bottom.
Further improvement, described lifting top rod can arrange multiple, for supporting backing plate, bears certain pressure.
Further improvement, the thickness of described EVA protective layer is 3-5mm, protection backing plate, not easily abrasion deformation.
Further improvement, the thickness of described ferro-aluminum composite bed is the half of steel plate layer.
The utility model adopts above technical scheme compared with prior art, has following technique effect:
Described backing plate have employed three-decker, makes backing plate more firm, not easily receives pressure and be out of shape, and in addition, is also provided with lifting top rod and supports, more firmly, extend service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, the utility model provides a kind of hydraulic press hydraulic die cushion, includes backing plate 1, is connected with lifting top rod 2 below described backing plate 1; Described backing plate is three-decker, is followed successively by EVA protective layer 3, ferro-aluminum composite bed 4 and steel plate layer 5 from top to bottom.
Wherein, the thickness of described EVA protective layer is 3-5mm; The thickness of described ferro-aluminum composite bed is 3-5cm, and the thickness of steel plate is 6-10mm.
For those of ordinary skills, can be equal to according to the technical solution of the utility model and utility model design thereof and replace or change, and all these change or replace the protection domain that all should belong to the claim appended by the utility model.
