Abstract
The utility model discloses a kind of vulcanizer lifting gears,Including pedestal,Supporting table,Master cylinder,Main oil pipe and main oil pump,Wherein control box is equipped in the side of the pedestal,Hydraulic control one-way valve is equipped in the main oil pipe,Auxiliary oil cylinder is equipped in the both sides of the pedestal,The auxiliary oil cylinder is connected with secondary oil pipe,Auxiliary oil pump is connected in one end of the secondary oil pipe,Solenoid valve is equipped in the secondary oil pipe,Pressure sensor is equipped in the top surface of the supporting table,The pressure sensor is connect with the input terminal of the control box,The output terminal of the control box respectively with the master cylinder,Auxiliary oil cylinder is connected with solenoid valve,Since auxiliary oil cylinder is smaller than master cylinder,So in the case where oil injecting speed is identical,The speed that auxiliary oil cylinder is promoted is faster than master cylinder,Therefore when supporting table is promoted,It is promoted by auxiliary oil cylinder,Master cylinder is just relied on only until really needing pressing mold,So as to accelerate the speed of supporting table promotion,The quality of product is ensured.
Description
Technical field
The utility model is related to a kind of elevating mechanism, especially a kind of vulcanizer lifting gear.
Background technology
At present, it in existing vulcanizer, is set below supporting table there are three master cylinder, mold is located in supporting table
On, since master cylinder itself is bigger, so when being promoted, the speed of master cylinder elongation is just very slow, therefore adhesive tape is in mold
The time of placement is undesirable so as to cause the vulcanization effect of product with regard to elongated.
Utility model content
The technical assignment of the utility model is to be directed to more than the deficiencies in the prior art, and provides a kind of vulcanizer lifting dress
It puts.
Technical solution is used by the utility model solves its technical problem：A kind of vulcanizer lifting gear, including
Pedestal, supporting table, master cylinder, main oil pipe and main oil pump, wherein control box is equipped in the side of the pedestal, in the main oil pipe
It is interior to be equipped with hydraulic control one-way valve, auxiliary oil cylinder is equipped in the both sides of the pedestal, the auxiliary oil cylinder is connected with secondary oil pipe, in the secondary oil
One end of pipe is connected with auxiliary oil pump, is equipped with solenoid valve in the secondary oil pipe, pressure sensing is equipped in the top surface of the supporting table
Device, the pressure sensor are connect with the input terminal of the control box, the output terminal of the control box respectively with the master cylinder,
Auxiliary oil cylinder is connected with solenoid valve.
It is further improved：Supporting block, the top of the auxiliary oil cylinder and the supporting block are equipped in the both sides of the supporting table
Connection.
It is further improved：The solenoid valve is hydraulic control one-way valve.
The advantages of the utility model：Since auxiliary oil cylinder is smaller than master cylinder, so in the case where oil injecting speed is identical, secondary oil
The speed that cylinder is promoted is faster than master cylinder, therefore when supporting table is promoted, is promoted by auxiliary oil cylinder, only waits until really
It needs just to rely on master cylinder during pressing mold, this not only accelerates the speed of supporting table promotion, shortens adhesive tape and in mold stops
The time stayed, and the vulcanization effect of product is also improved, ensure the quality of product.
Description of the drawings
Fig. 1 is the utility model structure diagram.
Fig. 2 is the utility model control framework figure.
1 pedestal, 2 master cylinders, 3 main oil pipes, 4 hydraulic control one-way valves, 5 main oil pumps, 6 auxiliary oil pumps, 7 solenoid valves, 8 supporting tables, 81
Pressure sensor, 82 supporting blocks, 9 auxiliary oil cylinders, 10 secondary oil pipes.
Specific embodiment
The utility model is described below with reference to the accompanying drawings of the specification.
As shown in the figure, a kind of vulcanizer lifting gear, including pedestal 1, supporting table 8, master cylinder 2, main oil pipe 3 and main oil
Pump 5 wherein being equipped with control box in the side of the pedestal 1, is equipped with hydraulic control one-way valve 4, at the bottom in the main oil pipe 3
The both sides of seat 1 are equipped with auxiliary oil cylinder 9, and the auxiliary oil cylinder 9 is connected with secondary oil pipe 10, and pair is connected in one end of the secondary oil pipe 10
Oil pump 6,10 are equipped with solenoid valve 7 in the secondary oil pipe, and solenoid valve 7 is located at the arrival end of secondary oil pipe 10, in the supporting table 8
Top surface is equipped with pressure sensor 81, and the pressure sensor 81 connect with the input terminal of the control box, the control box it is defeated
Outlet is connect respectively with the master cylinder 2, auxiliary oil cylinder 9 and solenoid valve 81.
Supporting block 82 is equipped in the both sides of the supporting table 8, the top of the auxiliary oil cylinder 9 is connect with the supporting block 85；
The solenoid valve 7 is hydraulic control one-way valve.
Its operation principle is：In use, control box is used to control the work of main oil pump 5, auxiliary oil pump 6 and solenoid valve 7 first
Make, supporting table 8 controls solenoid valve 7 to open, the oiling into auxiliary oil cylinder 9 of auxiliary oil pump 6, due to auxiliary oil cylinder 9 first in lifting process
Smaller than master cylinder 2, so the oily promotion demand that can meet auxiliary oil cylinder 9 that injection is a small amount of, this was allowed in the same time
Interior, the speed that auxiliary oil cylinder 9 is promoted is faster than master cylinder 2, and auxiliary oil cylinder 9 drives supporting table 8 to be promoted, supporting table 8 in elongation process
In lifting process, due to being provided that hydraulic control one-way valve 4 in main oil pipe 3, so supporting table 8 is in lifting process, main oil
2 internal pressure of cylinder is less than the pressure at main oil pump 5, such 2 self-priming oiling of master cylinder, and such master cylinder 5 keeps same with supporting table 8
Step is promoted, and when the pressure in supporting table 8 reaches setting value, control solenoid valve 7 is closed, at this time by main oil pump 5 to main oil
Oiling in cylinder 2 is risen to continue to lift up supporting table 8 by the support of master cylinder 2, increases the pressure to supporting table 8, so as to complete
Into vulcanization work.
After vulcanization, main oil pump 5, auxiliary oil pump 6 need to only be closed, solenoid valve 7 is opened, at this time master cylinder 2 and pair
Oil cylinder 9 is begun to decline under the action of the dead weight of supporting table 8.
The above description is only the embodiments of the present invention, and it does not limit the scope of the patent of the present invention, every
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is directly or indirectly used in
Other related technical areas are equally included in the patent within the scope of the utility model.
