Description
Technical field
The utility model relates to the machined field, is indirect extrusion machine recipient of using and the sync control device that pushes plug.
Background technology
The metal billet of heat must guarantee recipient and push being synchronized with the movement of plug, otherwise may cause in reverse extrusion process: (1) thermometal forms unwarranted charge from the faying face outflow of recipient and plug, makes extrusion process be difficult to proceed; (2) thermometal and recipient inwall produce frictional heating, cause the overheated and recipient inner wall abrasion destruction of extruded product.The recipient of at present external indirect extrusion machine and the Synchronization Control of pushing plug, the electric-hydraulic proportions that adopt are followed control synchronously, the installation position displacement sensor detects the displacement in the unit interval respectively on recipient and extruding plug, and its movement velocity of passing ratio valve regulation, to realize following synchronously, this mode is controlled complexity, cost height, and in actual production process, be subjected to influence that environment temperature and system pressure change greatly, relative accuracy is relatively poor, relative motion can't be eliminated, and frictional heating is difficult to avoid.
Summary of the invention
The purpose of this utility model is: provide a kind of and can make indirect extrusion machine recipient of using and the sync control device that pushes plug, the influence that this synchronous control system is not changed by environment and system pressure can guarantee that recipient and extruding plug do not have relative motion fully.
The technical solution of the utility model is: recipient that indirect extrusion machine is used and the sync control device that pushes plug, it is characterized in that: it comprises recipient, plug, the two-stage counterbalance valve, recipient and plug are on same axis, the opposite face of plug and recipient has the circular protrusions step surface, have in the recipient and the corresponding circular concavity step surface of plug circular protrusions step surface, the other end of plug circular protrusions step surface is connected with driving mechanism is coaxial, recipient is communicated with the oil circuit of two-stage counterbalance valve by the big chamber and the loculus of movable cylinder, the drive mechanism plug moves to the recipient direction, after making plug circular protrusions step surface and the circular concavity step surface of recipient face combining, the two-stage counterbalance valve applies an opposite force by movable cylinder to recipient, opposite force makes the same moved further of plug and recipient less than the driving force of described drive mechanism plug.
Described movable cylinder is connected with two-stage counterbalance valve, feed liquor valve and tapping valve, and feed liquor valve control fluid enters movable cylinder, and tapping valve control fluid is discharged movable cylinder; Feed liquor valve and tapping valve respectively have two groups, and one group communicates with the oil-feed and the oil extraction oil circuit in the big chamber of movable cylinder, and another group communicates with loculus oil-feed and oil extraction oil circuit.
Described plug and recipient are during with moved further, and automatic repairing is carried out by Fill valve in the big chamber of the movable cylinder that is connected with recipient, have prevented that it from inhaling sky and causing seal break-off and can't advance.
Characteristics of the present utility model are: the influence that the synchronous control system of recipient that this indirect extrusion machine is used and extruding plug is not changed by environment and system pressure, can guarantee that recipient and extruding plug do not have relative motion fully, have higher precision, and cost is low, simple and convenient.
Description of drawings
Below in conjunction with embodiment the utility model is described further.
Fig. 1 is indirect extrusion machine recipient of using and the sync control device structural representation that pushes plug.
Among the figure: 1, two-stage counterbalance valve; 2, Fill valve; 3, recipient; 4, plug; 5, feed liquor valve; 6, tapping valve; 7, movable cylinder.
The specific embodiment
As shown in Figure 1, recipient that indirect extrusion machine is used and the sync control device that pushes plug, which comprises at least recipient 3 and movable cylinder 7, plug 4, two-stage counterbalance valve 1, recipient 3 and plug 4 are on same axis, plug 4 has the step cutting pattern face with the opposite face of recipient 3, have in the recipient 3 and the corresponding circular concavity step surface of plug 4 circular protrusions step surfaces, the other end of plug 4 circular protrusions step surfaces is connected with driving mechanism is coaxial, recipient 3 communicates with the oil circuit of two-stage counterbalance valve 1 by movable cylinder 7 oil pockets that the rear end connects, drive mechanism plug 4 moves to recipient 3 directions, after making plug 4 circular protrusions step surfaces and recipient 3 circular concavity step surface faces combining, two-stage counterbalance valve 1 control movable cylinder 7 applies an opposite force to recipient 3, and opposite force is less than the driving force of described drive mechanism plug 4.
Recipient 3 is by two or four movable cylinders 7 drivings, steady to guarantee recipient 3 end faces and plug 4, what connect two or four movable cylinders 7 comprises two-stage counterbalance valve 1, feed liquor valve 5 and tapping valve 6, and feed liquor valve 5 control fluid enter recipient 3, and tapping valve 6 control fluid are discharged recipients 3.Feed liquor valve 5 and tapping valve 6 respectively have two groups, and one group communicates with (the opening the chamber) oil-feed of big chamber and the oil extraction oil circuit of movable cylinder 7, and another group communicates with loculus (lock chambers) oil-feed and oil extraction oil circuit.
During work, plug 4 advances and pushes hot billet, and its front end face step and recipient 3 front end faces are fitted, advance thereby promote recipient 3, and plug 4 active movements, recipient 3 is driven.Adjust the two-stage counterbalance valve 1 on the recipient lock chambers oil circuit, reach rational sealing force, prevent to be extruded metal and flow out, also avoided recipient 3 motions faster simultaneously than plug 4 from faying face to guarantee plug 4 and recipient 3 end faces.
Steadily reliable in order to guarantee the opposite force that recipient 3 produces, when plug 4 promoted recipients 3 and moves, recipient was opened the chamber and is carried out automatic repairing by Fill valve 2, had prevented that it from inhaling sky and causing seal break-off and can't advance.Thereby realized the complete Synchronization Control of no relative motion.
When recipient 3 independently movings by the feed liquor valve 5 on its movable cylinder oil circuit and tapping valve 6 realize, oil extraction, two-stage counterbalance valve 1 and Fill valve 2 are inoperative, rapidity and accuracy when not influencing recipient and moving alone.
