Description
Technical field
The utility model relates to a kind of punching machine safety brake apparatus, belongs to punching machine safety brake apparatus technical field.
Background technology
At present, the safety problem of operating punch machine, prevent that operator is because the wound that operate miss takes place frequently refers to, the damage to person accident of severed finger and so on, it is the large problem that China insider is concerned about always, for guaranteeing that punch press can reach safety in production and avoid personal injury accident, domestic design multiple punching machine emergency brake device or rigid press stepless emergency stop device, as use electricly or dead electricity magnetic friction plate gear transmission or pincerlike mechanism, the gear-driven structure of brake band, backing pin one side is fixed, the reaction force impact being subject to, may there is loosening phenomenon, and owing to not stopping, backing pin and turn key very easily depart from, be difficult to guarantee promptly and accurately brake hard.Also having a class is to use photoelectric induction type safety guard; the defect of this kind of device be once operating punch machine personnel be occur in punch press flywheel driving crank slide block from top dead centre, move downward; slide block also can move downward under inertia and self-gravity action, damages accident.
Summary of the invention
For solving the deficiencies in the prior art, the utility model provides a kind of safety catch, once can dangerously within any time of operation all can immediately brake, thus assurance operating personnel's personal safety.
To achieve these goals, the technical solution of the utility model is:
A kind of punching machine safety brake apparatus, comprise the gear wheel that arranges on a body, pedal, the lever system being connected with pedal, the operating mechanism being connected with lever system, the manipulation baffle plate on operating mechanism, bent axle, bent axle, be arranged at major key, auxiliary bond between gear wheel and bent axle, it is characterized in that described major key end connects the major key handle of " L " shape, described major key handle arranges movable axis vertically; Described gear wheel inner side arranges Semicircular tooth bar, be stuck on the axis body of bent axle, described movable axis contacts with tooth bar end, this end of tooth bar also connects extension spring, the other end by extension spring is connected with bed body, the other end of described tooth bar extends to bent axle bottom, and described manipulation baffle wedge is in the teeth groove of tooth bar.
As the improvement to technique scheme, described tooth bar end face setting is provided with the bearing bracket stand of rolling bearing, and described bearing bracket stand contacts with the side of gear wheel.
Brake apparatus of the present utility model, master between gear wheel and bent axle is good for and auxiliary bond forms two key formula positive clutches, when not stepping on pedal, handle baffle wedge in the teeth groove of tooth bar, the major key of two key type clutches and auxiliary bond proceed in bent axle completely, clutch is in neutral state, gear wheel is in idling conditions, punch press is not worked, when operator steps on pedal, handle baffle plate departs from from the teeth groove of tooth bar, tooth bar rotates up certain angle under the effect that connects spring, thereby make major key handle drive major key revolution, auxiliary bond also rotates to an angle, thereby completing impulsion does, when needs are braked at any time, operating personnel loosen pedal, handling baffle plate is inserted in the teeth groove of tooth bar, now rack drives major key handle resets, the major key of two key type clutches and auxiliary bond proceed in bent axle completely, clutch is in neutral state, gear wheel is in idling conditions, punch press action stops, thereby realize the safety arrestment of punch press, safety brake apparatus can be realized instant braking within any time of operation, guarantee operating personnel's personal safety.
Accompanying drawing explanation
Fig. 1 is punching machine safety brake apparatus service condition structure diagram of the present utility model.
Fig. 2 is the structure chart of punching machine safety brake apparatus of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model technology is described in further detail.
As depicted in figs. 1 and 2, punching machine safety brake apparatus of the present utility model, comprise on a body 1, pedal 2, the lever system 3 being connected with pedal 2, the operating mechanism 4 being connected with lever system 3, the manipulation baffle plate 5 on operating mechanism 4, bent axle 6, bent axle 6 gear wheel 7 that arranges, be arranged at major key 8, the auxiliary bond 9 of 6, gear wheel 7 and bent axle, it is characterized in that the end of described major key 8 connects the major key handle 10 of " L " shape, described major key handle 10 arranges movable axis 14 vertically; Described gear wheel 7 inner sides arrange Semicircular tooth bar 11, be stuck on the axis body of bent axle 6, described movable axis 14 contacts with tooth bar 11 ends, tooth bar 11 these ends connect extension spring 12, the other end by extension spring 12 is connected with bed body 1, the other end of described tooth bar 11 extends to bent axle 6 bottoms, and described manipulation baffle plate 5 is stuck in the teeth groove of tooth bar 11.Described tooth bar 11 end face intervals arrange a plurality of bearing bracket stands 13 that rolling bearing is installed, and described bearing bracket stand 13 contacts with the side of gear wheel 7.
Master strong 8 and auxiliary bond 9 between gear wheel 7 and bent axle 6 form two key formula positive clutches, when not stepping on pedal 2, handling baffle plate 5 is stuck in the teeth groove of tooth bar 11, the major key 8 of two key type clutches and auxiliary bond 9 proceed in bent axle 6 completely, clutch is in neutral state, gear wheel 7 is in idling conditions, punch press is not worked, when operator steps on pedal 2, handle baffle plate 5 departs from from the teeth groove of tooth bar 11, tooth bar 11 rotates up certain angle under the effect that connects spring 12, thereby make major key handle 10 drive major key 8 revolutions, auxiliary bond 9 also rotates to an angle, thereby completing impulsion does, when needs are braked at any time, operating personnel loosen pedal 2, handling baffle plate 5 is inserted in the teeth groove of tooth bar 11, this hour rack 11 drives major key handle 10 to reset, major key 8 and the auxiliary bond 9 of two key type clutches proceed in bent axle completely, clutch is in neutral state, gear wheel is in idling conditions, punch press action stops, thereby realize the safety arrestment of punch press.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
