The application discloses exemplary hydraulic cylinder supercharging device's of keeping silent theory of operation:
in the pressurizing process, the oil cylinder large cavity 76 is externally connected with a supplementary oil pipe, and the jaw oil cylinder 40 is connected with the pressurizing cylinder 70 through the first connecting pipe 50; and hydraulic oil is injected into one end of the stroke cavity 46 and one end of the pressure regulating cavity. Specifically, as shown in the drawing, in normal operation, oil is fed into the large oil cylinder cavity 76 through the supplementary oil pipe, so as to push the pressurizing piston 72 to move towards the pressurizing cavity 74, and the pressurizing piston 72 presses the hydraulic oil in the pressurizing cavity 74 to the right end of the stroke inner cavity 46 of the jaw oil cylinder 40, so as to push the plunger rod 41 to move leftward, thereby realizing that the jaw axial wedge 10 moves leftward in the axial direction. The axial movement of the jaw axial wedge 10 pushes the jaw radial wedge to move upwards in the radial direction through the inclined surface contact, so that the jaw radial wedge and the jaw fixing plate 30 clamp the winding drum together. In the pressure relief process, as shown in the figure, the oil supplementing pipe is externally connected to the small oil cylinder cavity 75, oil is injected into the small oil cylinder cavity 75 through the oil supplementing pipe, so that the pressurizing piston 72 moves rightward, oil in the stroke inner cavity 46 flows back into the pressurizing cavity 74, and therefore hydraulic oil pushes the plunger rod 41 to move rightward, the jaw axial wedge 10 moves rightward, the jaw radial wedge faces downward, and the jaw radial wedge is far away from the jaw fixing plate 30 and further separated from the winding drum. When the pressure is relieved, the oil in the large oil cylinder cavity 76 flows out through the supplementary oil pipe.
As shown in the figure, in the whole pressurizing or depressurizing process, the stroke inner cavity 46 is divided into a left end and a right end by the oil cylinder piston 45, the left end of the stroke inner cavity is communicated with the oil cylinder small cavity through the second connecting pipe, and the right end of the stroke inner cavity is communicated with the pressurizing cavity through the first connecting pipe. In the whole process, two ends of the stroke inner cavity are not communicated, and the pressurizing cavity, the oil cylinder large cavity and the oil cylinder small cavity are also not communicated with each other.
According to the jaw oil cylinder pressurizing device, due to the fact that the sectional areas of the pressurizing cylinder 70 and the oil cylinder large cavity 76 are different, the effect of increasing oil pressure is achieved, the pressure of the jaw oil cylinder 40 is increased to increase the thrust of the plunger rod 41, and the jaw axial wedge 10, the jaw longitudinal wedge 20 and the jaw fixing plate 30 are clamped tightly.
Will the utility model discloses a supercharging device installs on the reel that needs to keep silent, will keep silent the hydro-cylinder 40 and fix on keeping silent axial slide wedge 10. When the clamping device is used, the jaw oil cylinder 40 drives the jaw axial wedge 10 to move axially, and the jaw axial wedge 10 drives the jaw radial wedge to move radially through the inclined plane, so that a corresponding strip material is clamped.
In this application, change prior art's plunger cylinder for standard hydro-cylinder, avoid the oil leak phenomenon to produce, because the restriction in space, standard hydro-cylinder is under the condition of system pressure, because the restricted requirement that can't reach the required clamp force of keeping silent of bore size, so increase the pressurized cylinder to this standard hydro-cylinder to the pressure and the clamp force of keeping silent have been guaranteed.
In the prior art, the jaw oil cylinder 40 cannot be made large due to the limited space of the winding drum. Meanwhile, because the winding drum rotates, the oil pressure which needs to be provided for the jaw oil cylinder 40 through the rotary joint is very low. Therefore, the clamping force provided by the jaw cylinder 40 cannot meet the design requirement, and the pressure increasing cylinder 70 is added outside the winding drum of the jaw cylinder pressure increasing device of the application and solves the problem of insufficient oil pressure through the first connecting pipe 50 and the second connecting pipe 60.
The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application.
