Abstract
The invention relates to a hydraulic safety device of pendulum shears, which comprises a cylinder. A spherical pad is arranged at one end of the cylinder, a crankshaft hole is arranged at the other end of the cylinder, a piston cavity is arranged inside the cylinder, a piston is arranged in the piston cavity, and both the cylinder and the piston are provided with sealing rings. The hydraulic safety device has the advantages that the hydraulic safety device is accurate in rated safety load and is flexible in reaction, can unload automatically to guarantee safety of the pendulum shears once load is higher than the rated load, and can restore functions automatically once the load is lower than the rated load, so that production stop is avoided and production efficiency is guaranteed.
Description
Technical field
The present invention relates to a kind of fluid pressure warning device, especially relate to a kind of pendulum and cut fluid pressure warning device.
Background technology
Pendulum is cut and become as the cutting to length instrument in the machinery production instrument is very much universal, and therefore, it is very much important that its security also becomes.General pendulum shears security device is to be employed in the mode that adds safety pin on the shaft coupling, makes safety pin cut off load range and becomes big; But this mode makes pendulum cut when cutting off, to become and is not very accurate, and can cause that to be less than rated load just disconnected, causes the stopping production of production equipment; And it is also not disconnected that sometimes pendulum was cut rated load, do not have safety effect; Therefore, this safety device is not only cut safety to pendulum and is played certain influence, but also can influence production efficiency.
Summary of the invention
Technical problem to be solved by this invention provide a kind of rated load accurately, be quick on the draw and can cut fluid pressure warning device by self-discharging pendulum.
In order to solve the problems of the technologies described above, the present invention realizes through following technical scheme.
This pendulum is cut fluid pressure warning device, comprises cylinder body, and said cylinder body one end is provided with ball ring, and the other end is provided with crankshaft hole, and cylinder interior is provided with plunger shaft, is provided with piston in the said plunger shaft.
In order to prevent to produce leakage phenomenon in the cylinder body, said cylinder body and piston are provided with sealing ring.
Compared with prior art, usefulness of the present invention is: this pendulum cut fluid pressure warning device safety rated load accurately, be quick on the draw,, just can unload the assurance device security automatically as long as load is higher than rated load; As long as load is lower than just ability auto restore facility of rated load, need not to stop production, guarantee production efficiency.
Description of drawings:
Below in conjunction with accompanying drawing the present invention is further specified.
Fig. 1 is a structural representation of the present invention;
Among the figure: 1, cylinder body; 2, sealing ring; 3, ball ring; 4, plunger shaft; 5, piston;
6, crankshaft hole.
The specific embodiment:
Describe the present invention below in conjunction with the accompanying drawing and the specific embodiment:
A kind of pendulum shown in Figure 1 is cut fluid pressure warning device, comprises cylinder body 1, and an end of said cylinder body 1 is provided with ball ring 3, and said ball ring 3 can reduce radial load to the adverse effect that seals and hydraulic cylinder brings, and improves the service life of fluid pressure warning device; The other end of said cylinder body 1 is provided with crankshaft hole 6, can cooperate with the bent axle on the pendulum shearing machine through crankshaft hole 6; The inside of said cylinder body 1 is provided with plunger shaft 4, is provided with piston 5 in the plunger shaft 4, through the piston motion of piston 5 in plunger shaft 4, can cut pendulum and carry out hydraulic control; In order to guarantee the safety and the load of the motion of cylinder body 1 inner carrier.
It is emphasized that: above only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction; Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
