The pneumatic steel bar shearing machine mainly comprises a pneumatic shearing mechanism, a shearing cutter, a fixed cutter and a return spring, wherein the pneumatic shearing mechanism mainly comprises an air inlet channel, a slide air valve, an air inlet pipe, a main air channel, a piston valve and a piston hammer which are sequentially connected with one another; one side of the shearing cutter is movably connected with the fixed cutter through a rotating shaft while the other side of the shearing cutter is connected with the piston hammer of the pneumatic shearing mechanism by a pin; and the fixed cutter is connected with a returning frame through the return spring, and the returning frame is fixed on the surface of the pneumatic shearing mechanism. According to the pneumatic steel bar shearing mechanism, the shearing cutter is controlled by the pneumatic mechanism to shear steel bars, and the vibration amplitude of the pneumatic mechanism is controlled by virtue of the coordination of an energy storing and vibration absorbing spring and a control spring; the pneumatic steel bar shearing machine can implement continuous shearing, the shearing frequency and the shearing force of the machine can be automatically adjusted by adjusting the axial displacement of the pneumatic shearing mechanism, and an operator can control the magnitude of the shearing force freely so as to realize automatic frequency adjustment; and the pneumatic steel bar shearing machine has the advantages of high precision and low cost.
Description
Technical field
The present invention relates to the Machining Technology field, be specifically related to a kind of pneumatic cutter of reinforcing bar.
Background technology
The equipment that is used at present shear reinforcement roughly is divided into two kinds: a kind of is the gear mesh cut; Another kind is hydraulic shearing type.The gear mesh cut is on two mutual meshed gears, install respectively by a shear-blade, when gear turns to the corresponding position of two blades, reinforcing bar is cut off, because two shear the elimination that gears are cut off the motional inertia behind the reinforcing bar, is the wheel disc and the ring control of stopping that is mounted on the gear shaft other end, after cutting off reinforcing bar at every turn, the position that shear-blade stops is not constant, will cause like this shearing blanking always to have certain error, causes the waste of part reinforcing bar; The hydraulic shearing type cutting mechanism is to be linked to each other with shear-blade by hydraulic mechanism, this cutting mechanism is when shear reinforcement, the Displacement Ratio of reinforcing bar on shear-blade is larger, shear poor accuracy, and this cutting mechanism need to use hydraulic oil, just needs cost 2000-4000 is first to add a hydraulic oil, and use cost is high.
Summary of the invention
The purpose of this invention is to provide the pneumatic cutter of a kind of reinforcing bar, the problem that shear precision is poor, use cost is high that exists to solve prior art.
The technical solution adopted for the present invention to solve the technical problems is:
The pneumatic cutter of reinforcing bar, mainly by Pneumatic shearing mechanism, shear knife, dead knife and back-moving spring form, Pneumatic shearing mechanism is mainly by air intake duct, the slip air valve, air inlet pipe, main airway, piston valve and piston hammer are connected in sequence, it is stifled between air intake duct and the air inlet pipe upper end screw to be set, air inlet pipe lower end arranged outside spring base, be provided with control spring between spring base and the slip air valve, it is stifled that screw is set between air inlet pipe lower end and the main airway, piston valve is arranged on the outside, main airway lower end, the piston valve lower end is provided with piston hammer, and the energy storage damping spring is set between piston valve and the piston hammer; Shear knife one side is flexibly connected by rotating shaft and dead knife, and the opposite side of shear knife is connected with the piston hammer of Pneumatic shearing mechanism by pin, and dead knife is connected with the reset frame that is fixed on the Pneumatic shearing mechanism surface by back-moving spring.
The present invention's beneficial effect compared with prior art is:
1, precision is high, cost is low.Adopt pneumatic mechanism control shear-blade that reinforcing bar is sheared, pneumatic mechanism is controlled amplitude by the mutual coordination of energy storage damping spring and control spring; Can realize continuous shearing, shearing frequency and shearing dynamics are regulated automatically by the axial displacement of regulating Pneumatic shearing mechanism, and the size that the operator can control arbitrarily shearing force realizes automatic frequency adjustment.
2, can solve the displacement problem of reinforcing bar on shear-blade.Shear knife one side is connected and fixed cutter, and opposite side connects pneumatic mechanism, and reinforcing bar is difficult for rolling from blade when shearing.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present invention.
1 Pneumatic shearing mechanism, 2 shear knives, 3 dead knives, 4 back-moving springs, 5 reset frames, 6 pins, 7 rotating shafts, 11 air intake ducts, 12 slip air valves, 13 air inlet pipe, 14 control springs, 15 spring bases, 16 main airways, 17 piston valves, 18 energy storage damping springs, 19 piston hammers, 20 screws block up among the figure.
The specific embodiment
As shown in the figure: the pneumatic cutter of a kind of reinforcing bar, mainly by Pneumatic shearing mechanism 1, shear knife 2, dead knife 3 and back-moving spring 4 form, Pneumatic shearing mechanism 1 is mainly by air intake duct 11, slip air valve 12, air inlet pipe 13, main airway 16, piston valve 17 and piston hammer 19 are connected in sequence, screw stifled 20 is set between air intake duct 11 and air inlet pipe 13 upper ends, air inlet pipe 13 lower end arranged outside spring bases 15, be provided with control spring 14 between spring base 15 and the slip air valve 12, screw stifled 20 is set between air inlet pipe 13 lower ends and the main airway 16, piston valve 17 is arranged on the outside, main airway 16 lower ends, piston valve 17 lower ends are provided with piston hammer 19, between piston valve 17 and the piston hammer 19 energy storage damping spring 18 are set; Shear knife 2 one sides are flexibly connected by rotating shaft 7 and dead knife 3, and the opposite side of shear knife 2 is connected with the piston hammer 19 of Pneumatic shearing mechanism 1 by pin 6, and dead knife 3 is connected with the reset frame 5 that is fixed on Pneumatic shearing mechanism 1 surface by back-moving spring 4.
During work, air intake duct 11 and compressed gas source are connected, press from the top down Pneumatic shearing mechanism 1, by overcoming the elastic force of control spring 14, slip air valve 12 just can ascendingly be opened, gases at high pressure enter air inlet pipe 13, then gas is opened the screw stifled 20 between air inlet pipe 13 lower ends and the main airway 16, thereby gas enters main airway 16, the rapidly motion under the effect of gas of piston valve 17 this moment, thereby piston hammer 19 moves downward rapidly under the acting in conjunction of Compressed Gas and energy storage damping spring 18, drives the reinforcing bar that 2 pairs of shear knives are placed on the fixing island and shears, after cutting off reinforcing bar, under the effect of back-moving spring 4, Pneumatic shearing mechanism 1 is return upwards, and piston valve 17 is resetted.
