Description
Technical field
The utility model relates to a kind of pneumatic cutter.
Background technology
Pneumatic cutter is the one of lathe, safety, dependable performance, easy to operate, is applicable to the requirement of different scales different user, and with low cost, easy to use, energy-conservation, pollution-free.
Owing to adopting compressed air as working media, seal operation system is relied on to carry out power conversion, transmitting force and control signal to the pressure that gas extrusion produces, and easily containing impurity, steam, greasy dirt etc. in air, not only affect shear effect, and reduce the service life of equipment.
Utility model content
For the problems referred to above, the utility model provides a kind of pneumatic cutter, improves the cleannes of seal operation system, ensures shear effect, improves the service life of equipment.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of pneumatic cutter, comprise air compressor, air accumulator, servomotor driven change valve, described servomotor driven change valve is connected with an entrance of reversal valve, two outlets of described reversal valve are connected with bottom with the top of cylinder respectively, piston movable up and down is provided with in described cylinder, described top land is connected with lower cutter, corresponding upper cutter is fixed with directly over described lower cutter, lower cutter, formed for shearing the station waiting to shear object between upper cutter and servomotor driven change valve, it is characterized in that, water-cooling apparatus and oil expeller is disposed with between described air compressor and air accumulator, the filter of air is disposed with between described air accumulator and reversal valve, pressure-reducing valve and oil sprayer, described oil sprayer is connected with another entrance of reversal valve.
The compressed air that air compressor produces, first cool through water-cooling apparatus, then after the preliminary purification process of oil expeller stored in air accumulator, removal of impurities is carried out again through filter, finally reach cylinder, cylinder promotes piston and moves up or down, makes to form sheared edge between lower cutter and upper cutter.Through filtration repeatedly, removal of impurities, go out wet goods operation, improve the cleannes of seal operation system, ensure shear effect, improve the service life of equipment.
The beneficial effects of the utility model are: the cleannes improving seal operation system, ensure shear effect, improve the service life of equipment.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of pneumatic cutter of the utility model;
The mark implication of accompanying drawing is as follows:
1: air compressor; 2: water-cooling apparatus; 3: oil expeller; 4: air accumulator; 5: filter; 6: pressure-reducing valve; 7: oil sprayer; 8: servomotor driven change valve; 9: reversal valve; 10: cylinder; 11: wait to shear object; 12: cooling water; 13: lower cutter; 14: upper cutter.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, technical solutions of the utility model are described in further detail, to make those skilled in the art better can understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.
As shown in Figure 1, a kind of pneumatic cutter, comprises air compressor 1, air accumulator 4, servomotor driven change valve 8, and servomotor driven change valve 8, also known as stroke valve, is mainly used to the stroke controlling mechanical moving element, also can be used as safety valve.Be two servomotor driven change valves 8 in Fig. 1, the right side of servomotor driven change valve 8 is provided with back-moving spring, and left end is provided with push rod, and described servomotor driven change valve 8 is connected with an entrance of reversal valve 9, the entrance namely bottom reversal valve 9.
Be disposed with water-cooling apparatus 2 and oil expeller 3 between described air compressor 1 and air accumulator 4, water-cooling apparatus 2 can be cooler, can be cooled by cooling water 12.Be disposed with the filter 5 of air, pressure-reducing valve 6 and oil sprayer 7 between described air accumulator 4 and reversal valve 9, described oil sprayer 7 is connected with another entrance of reversal valve 9, i.e. the entrance at reversal valve 9 top.
Two outlets of described reversal valve 9 are connected with bottom with the top of cylinder 10 respectively, and be provided with piston movable up and down in described cylinder 10, cylinder 10 is divided into upper and lower two cavity volumes by piston.Described top land is connected with lower cutter 13, corresponding upper cutter 14 is fixed with directly over described lower cutter 13, lower cutter 13, formed between upper cutter 14 and servomotor driven change valve 8 and wait to shear the station of object 11 for shearing, when upper and lower two cavity volume air pressure are different, piston can be promoted and do upper and lower shearing motion.
The compressed air that air compressor 1 produces, first cool through water-cooling apparatus 2, then after the preliminary purification process of oil expeller 3 stored in air accumulator 4, removal of impurities is carried out again through filter 5, finally reach cylinder 10, cylinder 10 promotes piston and moves up or down, makes to form sheared edge between lower cutter 13 and upper cutter 14.Through filtration repeatedly, removal of impurities, go out wet goods operation, improve the cleannes of seal operation system, ensure shear effect, improve the service life of equipment.
Concrete shear history is as follows:
Compressed air arrives cylinder 10, and now spool is shifted onto the tip position in Fig. 1 by the A cavity pressure of reversal valve 9, and the upper cavity volume pressurising of cylinder 10, piston is in bottom cylinder 10, and the sheared edge of cutter is opened.When feed mechanism will wait shear object 11 make a gift to someone cutter and reach the position of setting time, the push rod pressurized of servomotor driven change valve 8, push rod moves right, the A chamber of reversal valve 9 communicates with air by servomotor driven change valve 8, the lower cavity volume of cylinder 10 communicates with compressed air, and piston driving lower cutter 13 fast upward motion also will wait that shearing object 11 cuts.After shearing object 11 is cut, namely depart from servomotor driven change valve 8, servomotor driven change valve 8 resets, and all parts gets back to again position in Fig. 1, and a circulation terminates.
Wherein, air accumulator 4 is provided with safety valve, Pressure gauge, pressure-reducing valve 6 is provided with Pressure gauge.
Preferred feed mechanism is connected with computer, convenient accurately control and monitoring.
These are only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in the technical field that other are relevant, be all in like manner included in scope of patent protection of the present utility model.
