Abstract
The utility model discloses an elasticity is hydraulic die cushion for hydraulic press, including the backing plate, the backing plate below is connected with the support column, the backing plate be the four -layer structure, by last EVA protection film, ferro -aluminum composite bed, spring layer and the steel deck of being in proper order under to. The utility model discloses a backing plate has adopted the four -layer structure for the backing plate is more firm not only, and be difficult for receiving pressure and warp, but also utensil elasticity, it is bigger to bear pressure, in addition, still being equipped with the support column and supporting, more firm has prolonged life.
Description
Technical field
The utility model belongs to hydraulic press field, relates to a kind of elastic hydraulic machine 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 be to provide a kind of long service life, not yielding, more firmly there is flexible 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 elastic hydraulic machine hydraulic die cushion, includes backing plate, be connected with support column below described backing plate; Described backing plate is four-layer structure, is followed successively by EVA diaphragm, ferro-aluminum composite bed, spring layer and steel plate layer from top to bottom.
Further improvement, described support column can arrange multiple, for supporting backing plate, bears certain pressure.
Further improvement, the thickness of described EVA diaphragm is 1-3mm, protection backing plate, not easily abrasion deformation.
Further improvement, the thickness of described ferro-aluminum composite bed is the half of steel plate layer.
Further improvement, described spring layer is made up of multiple spring.
The utility model adopts above technical scheme compared with prior art, has following technique effect:
Described backing plate have employed four-layer structure, makes backing plate not only more firm, not easily receives pressure and be out of shape, but also tool elasticity, bear pressure larger; In addition, be also provided with support column and support, 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 elastic hydraulic machine hydraulic die cushion, includes backing plate 1, is connected with support column 6 below described backing plate 1; Described backing plate 1 is four-layer structure, is followed successively by EVA diaphragm 2, ferro-aluminum composite bed 3, spring layer 4 and steel plate layer 5 from top to bottom.
Wherein, the thickness of described EVA diaphragm is 1-3mm, and backing plate is not easily worn; The thickness of described ferro-aluminum composite bed is 3-5cm, and the thickness of steel plate is 6-10mm, and spring layer is made up of multiple spring, makes backing plate have elasticity, bears pressure larger.
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.
