Abstract
The utility model relates to an energy-saving device for a band sawing machine. The energy-saving device comprises an oil cylinder, an oil pump, an oil pump motor, a filter screen, an overflow valve, a three-position four-way electromagnetic valve and a clamping oil cylinder which compose a hydraulic clamping loop, and a hydraulic control non-return valve is arranged in an oil supply pipe between the three-position four-way electromagnetic valve and the clamping oil cylinder. The energy-saving device is characterized in that a pressure relay is arranged in an oil supply pipe between the hydraulic control non-return valve and the clamping oil cylinder, and is connected with the oil pump motor; and the oil pump motor is controlled by the pressure relay. The energy-saving device enables the oil pump to stop running automatically for saving energy after a workpiece is clamped tightly.
Description
Technical field
The utility model relates to a kind of band saw machine, particularly a kind of band sawing machine energy saver.
Background technology
Band saw machine is the visual plant of workpiece section sawing processing, and during its work, workpiece drives adjustable clamp by clamping cylinder usually and clamps.After workpiece clamps, do not become flexible in order to guarantee workpiece, in whole sawing process, the oil pump in the existing band sawing machine is working without cessation all the time, makes clamping cylinder keep certain oil pressure, to guarantee adjustable clamp enough clamping forces is arranged.But working because workpiece clamps its oil pump of back always, like this, not only influencing the physical life of oil pump and other Hydraulic Elements, and need expend a large amount of electric energy.
Summary of the invention
The utility model provides a kind of band sawing machine energy saver, make clamping cylinder drive the active clamp clamping of workpieces after, oil pump is can autostop energy-conservation.For this reason, the utility model is by the following technical solutions:
A kind of band sawing machine energy saver, comprise oil cylinder, oil pump, Oil pump electrical machinery, screen pack, overflow valve, three position four-way electromagnetic valve and clamping cylinder in the clamping hydraulic loop, be provided with hydraulic control one-way valve in the fuel feeding road between three position four-way electromagnetic valve and the clamping cylinder, it is characterized in that: be provided with pressure switch in the fuel feeding road between described hydraulic control one-way valve and the clamping cylinder, pressure switch connects and the control Oil pump electrical machinery.
The beneficial effects of the utility model are: by set up pressure switch and hydraulic control one-way valve in the clamping hydraulic loop, after workpiece clamps, can make the oil pump autostop energy-conservation.
Description of drawings
Fig. 1 is the utility model hydraulic principle structural representation.
The specific embodiment
Accompanying drawing marking explanation: 1-clamping cylinder, 2-pressure switch, 3-hydraulic control one-way valve, 4-three position four-way electromagnetic valve, 5-overflow valve, 6-screen pack, 7-oil pump, 8-Oil pump electrical machinery, 9-oil cylinder.
As shown in Figure 1, a kind of band sawing machine energy saver, comprise oil cylinder 9, oil pump 7, Oil pump electrical machinery 8, screen pack 6, overflow valve 5, three position four-way electromagnetic valve 4 and clamping cylinder 1 in the clamping hydraulic loop, be provided with hydraulic control one-way valve 3 in the fuel feeding road between three position four-way electromagnetic valve 4 and the clamping cylinder 1, be provided with pressure switch 2 in the fuel feeding road between described hydraulic control one-way valve 3 and the clamping cylinder 1, pressure switch 2 connects and control Oil pump electrical machinery 8.
Described hydraulic control one-way valve 3 can be stacking type hydraulic control check valve.
During the utility model work, behind the active clamp clamping of workpieces on the 1 rotating band sawing machine of the clamping cylinder in the clamping hydraulic loop, by pressure switch 2 effects, Oil pump electrical machinery 8 outages, oil pump 7 is shut down.
After oil pump 7 was shut down, the hydraulic control one-way valve 3 in its clamping hydraulic loop was closed immediately, make in this clamping hydraulic loop to keep certain pressure, thus the clamping of assurance workpiece.Pressure maximum duration in the utility model clamping hydraulic loop can reach 3 hours.
When the pressure in the above-mentioned clamping hydraulic loop reduced to the minimum of a value that pressure switch 2 sets, pressure switch 2 was by the work of starting shooting again of circuit control oil pump, the pressure that reduces in the compensation hydraulic circuit.
After the pressure in the hydraulic circuit reached the setting value that needs, pressure switch 2 was controlled Oil pump electrical machinery 8 outages again, and oil pump 7 is shut down.
The utility model is compared with the clamping hydraulic loop on the existing band sawing machine, has only set up pressure switch 2 in the fuel feeding road between hydraulic control one-way valve 3 and clamping cylinder 1, and is simple in structure.And existing band sawing machine is after the sawing machine start, and its oil pump is just in running order always, and electric energy is wasteful, and Hydraulic Elements easily break down.And the utility model shuts down oil pump after can reaching the workpiece clamping, can significantly reduce the oil pump working time, saves energy.Simultaneously, Hydraulic Elements are in the low temperature for a long time work, prolong the physical life of Hydraulic Elements.
What should be understood that is: the foregoing description is just to explanation of the present utility model, and any innovation and creation that do not exceed in the utility model connotation scope all fall within the protection domain of the present utility model.
