Abstract
The utility model relates to a multi-station die forging hydraulic pressure machine which comprises an upper crossbeam, an operating platform, guide pillars, a sliding block and a master cylinder. Four corners of the upper crossbeam are connected with four corners of the operating platform through the guide pillars. The sliding block which fits in with the guide pillars in a sliding mode is arranged below the upper crossbeam. The sliding block is driven by the master cylinder which is arranged on the upper crossbeam. The multi-station die forging hydraulic pressure machine is characterized in that a left side of the operating platform and a right side thereof are provided with horizontal piston cylinders which are symmetrically placed. The two horizontal piston cylinders control the multi-station die forging hydraulic pressure machine to synchronously push-off or go back through synchronous control cartridge valve blocks of a hydraulic system. Due to the fact that the left side of the operating platform and the right side thereof are provided with the horizontal piston cylinders, two horizontal piston rods synchronously drive and match the master cylinder to suppress from three faces, and therefore a left direction runner of a valve and a right direction runner thereof and a center hole of the valve body of a valve pool are punched out. The multi-station die forging hydraulic pressure machine is capable of avoiding the defects arising in moulding, guaranteeing dimension error between a left end of the valve body and a right end thereof and dimensional accuracy and improving the quality of products.
Description
Technical field
The utility model relates to a kind of multi-functional position stamp forging hydraulic press, particularly a kind of multi-functional position stamp forging hydraulic press that forges power station valve.
Background technology
Power station valve also claims the power station special valve, mainly is applicable on the pipeline of the various systems of firepower power station, cuts off or connect the pipeline medium.Traditional power station valve adopts casting structure, and its shortcoming is: cast member is prone to trachoma, bubble, and then affects the reliability of product, so its technological requirement is high, and qualification rate is low, requires more very at the power station valve that is applied to nuclear power station.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of multi-functional position stamp forging hydraulic press that can forge power station valve.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of multi-functional position stamp forging hydraulic press, comprise entablature, workbench, guide pillar, slide block and master cylinder, described entablature be connected with workbench four jiaos connect by guide pillar, the entablature below arranges the slide block that is slidingly matched with guide pillar, described slide block is driven by the master cylinder that is installed on the entablature, its innovative point is: the left and right side of described workbench also is equipped with symmetrically arranged horizontal piston cylinder, and described two horizontal piston cylinders are controlled simultaneous ejection by the Synchronization Control Cartridge inserted valve integrated block in the hydraulic system or return.
The utility model has the advantage of: the left and right side at workbench is installed the horizontal piston cylinder, promote synchronously to cooperate master cylinder to suppress from three faces by two horizontal piston bars, stamp out the left and right directions runner of valve body and the valve body mesopore that spool is installed, avoid casting the defective of appearance, and guaranteed scale error and the dimensional accuracy at two ends, the valve body left and right sides, improve the quality of products.
Description of drawings
Fig. 1 is the utility model multi-functional position stamp forging hydraulic press structural representation.
Fig. 2 is the Synchronization Control Cartridge inserted valve integrated block hydraulic schematic diagram of the utility model left and right horizontal piston cylinder.
The specific embodiment
As shown in Figure 1, comprise entablature 1, workbench 2, guide pillar 3, slide block 4 and master cylinder 5, four jiaos of being connected with workbench of entablature 1 connect by guide pillar 3, and entablature 1 below arranges the slide block 4 that is slidingly matched with guide pillar 3, and slide block 4 is driven by the master cylinder 5 that is installed on the entablature 1.
The left and right side of workbench 2 also is equipped with symmetrically arranged horizontal piston cylinder 6,7, two horizontal piston cylinders 6,7 eject synchronously or retreat by the Synchronization Control Cartridge inserted valve integrated block 8 in the hydraulic system, 9 controls.
Fig. 2 shows horizontal piston cylinder Synchronization Control Cartridge inserted valve integrated block hydraulic principle figure, and the specific works principle is:
Left horizontal piston cylinder 6 advanced state: YA11 gets electric, and left side DG50 throttling plug-in unit A opens, and regulates the length of plug-in unit upper screw, and the internal plug openings of sizes is changed, and has namely realized the adjusting of inlet flow rate; YA13 gets electric, and plug-in unit B opens, left side rodless cavity oil-feed, and the rod chamber support force is regulated by overflow valve m.
Left horizontal piston cylinder 6 fallback states: YA11 gets electric, and left side DG50 throttling plug-in unit A opens; YA14 gets electric, and plug-in unit C opens, left side rod chamber oil-feed, and rod chamber is return power and is regulated by overflow valve n; YA15, YA16 gets electric, and plug-in unit D, E open, and regulate the length of DG32 plug-in unit E upper screw, and the internal plug openings of sizes is changed, and have namely realized the drain the oil adjusting of flow of left side rodless cavity.
Right horizontal piston cylinder 7 advanced state: YA12 gets electric, and right side DG50 throttling plug-in unit G opens, and regulates the length of plug-in unit upper screw, and the internal plug openings of sizes is changed, and has namely realized the adjusting of inlet flow rate; YA17 gets electric, and plug-in unit H opens, right side rodless cavity oil-feed, and the rod chamber support force is regulated by overflow valve p.
Right horizontal piston cylinder 7 fallback states: YA12 gets electric, and right side DG50 throttling plug-in unit G opens; YA18 gets electric, and plug-in unit I opens, right side rod chamber oil-feed, and rod chamber is return power and is regulated by overflow valve q; YA19, YA20 gets electric, and plug-in unit J, K open, and regulate the length of DG32 plug-in unit K upper screw, and the internal plug openings of sizes is changed, and have namely realized the drain the oil adjusting of flow of right side rodless cavity.
By the adjusting of each plug-in unit, so that left and right horizontal piston cylinder synchronizing moving guarantees to suppress rear valve body left and right sides consistent size.
