Abstract
The utility model relates to a buffer cylinder of a blanking hydraulic press, which comprises a cylinder body, a piston rod arranged in the cylinder body, and an oil inlet and an oil outlet, which are respectively connected with a rod cavity and a non-rod cavity of the cylinder body. The innovative points of the buffer cylinder lie in that a regulating rod is arranged at the center of the piston rod and connected with internal screw threads and external screw threads of the piston rod in a matched manner; and a plurality of return springs are connected between the end part of the piston rod in the non-rod cavity of the cylinder body and the cylinder body. The buffer cylinder has the advantages that the regulating rod is arranged at the center of the piston rod and connected with internal screw threads and external screw threads of the piston rod in a matched manner, so that when the length of the buffer cylinder needs to be regulated, the buffer cylinder can extend out or retract through rotating the regulating rod, thereby changing the length of the buffer cylinder; and the return springs can be used for automatic return in a non-oil-filled state in the non-rod cavity.
Description
Technical field
The utility model relates to a kind of stamping-out hydraulic press cushion dashpot, particularly a kind of adjustable in length stamping-out hydraulic press cushion dashpot.
Background technique
Buffering hydraulic cylinder is the oil hydraulic cylinder with pooling feature, in mechanical field extensive uses such as excavator or stamping-out hydraulic presses.Traditional stamping-out hydraulic press cushion dashpot comprises cylinder body, is located at the piston rod in the cylinder body, and the oil inlet and outlet that is connected with rodless cavity with the cylinder body rod chamber respectively, and when the slide block of stamping-out hydraulic press following time slowly, rodless cavity is oil-filled, realizes the buffering of corresponding tonnage.The shortcoming of this structure is: the cushion dashpot height is fixed, and the stamping-out hydraulic press of different size need customize the cushion dashpot of respective length, and the fabricating cost height does not have versatility.
The model utility content
The technical problems to be solved in the utility model provides a kind of adjustable in length stamping-out hydraulic press cushion dashpot.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of stamping-out hydraulic press cushion dashpot, comprise cylinder body, be located at the piston rod in the cylinder body, and the oil inlet and outlet that is connected with rodless cavity with the cylinder body rod chamber respectively, its innovative point is: described piston rod center is provided with an adjustable lever, and this adjustable lever and piston rod internal and external threads are connected; Be connected with several return springs between piston rod end in the described cylinder body rodless cavity and the cylinder body.
Advantage of the present utility model is: the piston rod center is provided with an adjustable lever, this adjustable lever and piston rod internal and external threads are connected, needing to regulate length is, can be by the rotation adjustable lever, it is stretched out or withdraw, thereby realize the change of length, return spring can be used for non-oil-filled state self-return at rodless cavity.
Description of drawings
Accompanying drawing is the utility model stamping-out hydraulic press cushion dashpot structural representation.
Embodiment
As shown in drawings, comprise cylinder body 1, piston rod 2, adjustable lever 3, return spring 4.
Be provided with piston rod 2 in the above-mentioned cylinder body 1, this piston rod 2 is divided into rod chamber and rodless cavity with cylinder body 1 inner chamber, and two chambeies connect oil inlet and outlet respectively.Be connected with several return springs 4 between piston rod 2 ends in cylinder body 1 rodless cavity and the cylinder body 1.The center of piston rod 2 is emptied, and establishes internal thread, is with externally threaded adjustable lever 3 to fix with piston rod 2 screw-thread fit, by unscrewing or screw adjustable lever 3, can change the length of whole cushion dashpot, is convenient to adapt to the stamping-out hydraulic press of different size.
Claims (1)
1. stamping-out hydraulic press cushion dashpot, comprise cylinder body, be located at the piston rod in the cylinder body, and the oil inlet and outlet that is connected with rodless cavity with the cylinder body rod chamber respectively, it is characterized in that: described piston rod center is provided with an adjustable lever, and this adjustable lever and piston rod internal and external threads are connected; Be connected with several return springs between piston rod end in the described cylinder body rodless cavity and the cylinder body.
