Abstract
The invention relates to a hydraulic cylinder plunger installation structure for a powder hydraulic press, comprising a cylinder body, a plunger and a guide sleeve. The hydraulic cylinder plunger installation structure is characterized in that a center blind hole is arranged at the outer connecting end of the plunger; a spherical column is arranged in the center blind hole; an unbalance loading gap is reserved between the spherical column and the center blind hole; a spherical pad is arranged between the spherical column and the center blind hole; a spherical pad is arranged between the other end of the spherical column and the outer connecting piece; two annular lug bosses are arranged on the spherical column; and two split flanges are symmetrically arranged between the two annular lug bosses, wherein one flange is connected with the plunger, and the other flange is clamped on the annular lug boss positioned outside and connected with the outer connecting piece. When the hydraulic press bears unbalance load, the spherical column realizes the unbalance load compensation along the spherical trace in a certain angle range and the wear of the plunger and other relevant components is reduced to the minimum when large unbalance force is applied, thereby prolonging the service life of the components and improving the work efficiency of the equipment.
Description
Technical field
The invention belongs to hydraulic press manufacturing technology field, particularly relate to a kind of cylinder plunger mounting structure that is used on the powder hydraulic press.
Background technology
Continuous progress along with China's science and technology, the demand of heavy-duty machinery is also increasing, and the application of large-tonnage hydraulic press is also more and more, especially free-forging hydraulic, tonnage rose to tons up to ten thousand by former several kilotons, and former piston structure can not satisfy the instructions for use of large-tonnage hydraulic press.Traditional cylinder plunger mounting structure is: plunger of just simple installation in cylinder body, and the output of plunger connects outer connector, and this kind structure is applicable to that the hydraulic press of little tonnage uses; When the hydraulic press tonnage was big, the offset loading force that this kind structure plunger is born was bigger, the long-time use, and not only plunger is damaged, but also can accelerate the wearing and tearing between other associated members, even the generation of accidents such as connecting bolt fractures can occur.
Summary of the invention
The present invention for solve the technical problem that exists in the known technology provide a kind of simple in structure, easy to install, the anti-bias load ability is strong, improves the cylinder plunger mounting structure on the powder hydraulic press of being used for of service life of equipment.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
A kind of cylinder plunger mounting structure that is used on the powder hydraulic press, comprise cylinder body, be installed in interior plunger of cylinder body and the guide pin bushing between plunger and the cylinder body, it is characterized in that: the outer link of described plunger is provided with central blind hole, the sphere post is installed in the central blind hole, leaves the unbalance loading gap between sphere post and the central blind hole; Be provided with ball ring between sphere post and the central blind hole; Be provided with ball ring between the other end of described sphere post and the outer connector; Described sphere post is provided with two annular boss, is arranged with two opposite opened flanges between two annular boss, and one of them flange is stuck in and is positioned on the inboard annular boss, and links to each other with plunger by securing member, keeps sphere post and ball ring to fit simultaneously; Another flange is installed on the annular boss that is positioned at the outside, and is connected with outer connector by securing member, keeps sphere post and ball ring to fit simultaneously.
The present invention can also adopt following technical measures:
Described sphere post and between the ball ring at sphere post two ends, be provided with oil leab.
All adopt the conical surface or sphere to cooperate between two annular boss on the described sphere post and the flange.
Advantage and good effect that the present invention has are: because the present invention adopts technique scheme, i.e. mounting spherical post in the central blind hole of plunger, the two ends of sphere post all cooperate ball ring, in the hydraulic press pressing process, when hydraulic press bears unbalance loading, the sphere post will be realized the unbalance loading compensation along the sphere track of ball ring in certain angular range, guarantee that the wearing and tearing of plunger and other associated members drop to minimum when being subjected to big offset loading force, thereby improve the service life and the equipment operating efficiency of parts.Flange in the said structure all adopts the opposite opened structure in addition, and this structure is convenient to install, is dismantled and maintenance.To have the anti-bias load ability strong in the present invention in sum; Simple in structure; Be convenient to install, dismantle and maintenance; Improve the advantages such as service life of parts.The present invention is specially adapted on the higher large-tonnage hydraulic forging press of anti-bias load Capability Requirement.
