Abstract
The invention discloses a hydraulic pad for a hydraulic machine. The hydraulic pad comprises a pad plate, and a lifting ejector rod is connected below the pad plate; and the pad plate is of a three-layer structure, and an EVA protection layer, an aluminum iron composite layer and a steel plate layer are sequentially arranged from top to bottom. The three-layer structure is adopted in the pad plate, and the pad plate is firmer, and is not prone to deformation due to pressure; and in addition, the lifting ejector id further arranged for supporting, the pad is firmer, and the service life is prolonged.
Description
Technical field
The invention belongs to hydraulic press field, relate 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.
Summary of the invention
The object of the present invention is to provide a kind of long service life, not yielding, more firmly hydraulic press hydraulic die cushion.
The present invention 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 present invention 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 invention.
Detailed description of the invention
As shown in Figure 1, the invention provides a kind of hydraulic press hydraulic die cushion, include backing plate 1, below described backing plate 1, be connected with lifting top rod 2; 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 technical scheme of the present invention and inventive concept thereof and replace or change, and all these change or replace the protection domain that all should belong to the claim appended by the present invention.
