Abstract

The invention discloses a device for connecting a main plunger and a pressure head of a vertical hydraulic machine and relates to a vertical hydraulic machine. The device is characterized in that the main plunger and the spherical surface of an upper sphere body are contacted and connected through a bolt; the main plunger and the plane of a lower sphere body are connected through the bolt; the upper sphere body and the lower sphere body have the same sphere center; the pressure head and the plane of a sphere supporting pad are connected through the bolt; the spherical surface of the sphere supporting pad is contacted with the spherical surface of the lower sphere body; a pressure flange and the pressure head are connected through the bolt; and the side curved surface of the pressure flange is contacted with the side curved surface of the upper sphere body. The device solves the problems that in a structure of directly connecting the main plunger and the pressure head through the pressure flange, a copper sleeve of a main cylinder has serious uneven wear of the seal caused by uneven loading of a presser and in a structure of adopting single spherical surface contact and pressure flange connection between the main plunger and the pressure head, the bolt for connecting the pressure flange and the pressure head is easy to break.

Description

technical field

[0001] The present invention relates to vertical hydraulic machines. Background technique

[0002] The connection device between the main plunger and the pressure head of the vertical hydraulic press in the prior art mainly has two structures:

[0003] 1) The main plunger and the pressure head are directly connected through the pressure flange (such as figure 1 As shown), its disadvantage is that when the surface of the workpiece being pressed has a large curvature, the press will be eccentrically loaded, and its eccentrically loaded force will directly act on the main plunger through the connection key between the indenter and the main plunger. As a result, the main plunger bears a large eccentric load, and the copper sleeve and seal of the main cylinder are severely worn. Therefore, the copper sleeve and seal need to be replaced frequently.

[0004] 2) The main plunger and the pressure head adopt a single spherical contact and are connected by a pressure ...
