The hydraulic die cushion device of frame type hydraulic press
Technical field
The utility model relates to a kind of hydraulic press, is specifically related to a kind of biliquid pressure pad device of frame type hydraulic press.
Background technology
In the market during hydraulic press compacting covering goods, generally be to realize by loading and unloading two kinds of moulds at the product of twice moulding, its processing step is many, efficient is low, precision is difficult to control.
The utility model content
The utility model provides a kind of hydraulic die cushion device of convenient and practical frame type hydraulic press.
The utility model provides a kind of hydraulic die cushion device of frame type hydraulic press, comprise entablature, slide block, on take blame for others, go up hydraulic die cushion, go up additional stations, travelling table, hydraulic die cushion, take blame for others, workbench, master cylinder, column etc., its innovative point is: be equipped with the hydraulic die cushion device in described slide block, the workbench.
Hydraulic die cushion device in the described slide block, by hydraulic die cushion, on take blame for others and push rod, the piston rod of taking blame for others constitute; Built-in being fixed in the slide block of taking blame for others on described, hydraulic die cushion and on the piston rod of taking blame for others be connected and fixed, push rod is housed on the hydraulic die cushion, described hydraulic die cushion is parallel to the working face of slide block.
Hydraulic die cushion device in the described workbench by hydraulic die cushion, take blame for others, piston rod, push rod constitute, described built-in being fixed in the workbench of taking blame for others, the piston rod of taking blame for others is fixedlyed connected with hydraulic die cushion, and push rod is housed on the hydraulic die cushion; Described hydraulic die cushion is parallel to the last plane of workbench.
Taking blame for others and can be one in the described hydraulic die cushion device also can be several, the equalization of taking blame for others, symmetrical distribution in slide block, the workbench.
The advantage of above structure is: this structure adopts upper and lower hydraulic die cushion, in the different time periods product is suppressed pull and stretch with upper and lower hydraulic die cushion by slide block, make product formation staged that a mould only need be installed and get final product moulding, convenient and practical, the high efficiency of adaptation suitability for industrialized production.
Description of drawings
Figure is the utility model structural representation.
The specific embodiment
As shown in the figure, be provided with in the slider of hydraulic press 1 and take blame for others 2, hydraulic die cushion 3 with on take blame for others 2 piston rod fixedly connected.Upper ejector pin 4 is housed on hydraulic die cushion 3, and push rod 4 is positioned at the aperture of additional stations 5.
As shown in the figure, be provided with in the hydraulic press workbench 8 and take blame for others 9, hydraulic die cushion 10 is fixedlyed connected with 9 the piston rod of taking blame for others.Push rod 6 is housed on hydraulic die cushion 10, and push rod 6 is positioned at the aperture of travelling table 7.
In specific design, take blame for others 2, taking blame for others 9 can be one, also can be several, the equalization of taking blame for others, symmetrical distribution in slide block, the workbench.Push rod 4,6 is provided with several, and is impartial, be symmetrically distributed on the hydraulic die cushion 3,10.
When the stepped covering goods of compacting, taking blame for others before this 9 ejects, and hydraulic die cushion 10 rises, and push rod 6 ejects, and slide block 1 presses down, and finishes a compression moulding; Taking blame for others subsequently 2 ejects, and hydraulic die cushion 3 is descending, takes blame for others 4 to eject, and finishes secondary compression moulding.
