Description
Technical field
The present invention relates to metallurgical technology field, in particular to a kind of connecting structure and hydraulic press.
Background technique
Hydraulic press works using water as hydraulic medium, on the steel rolling line of many smelters all using hydraulic press into
The rolling of row bar.
Currently, as shown in Figure 1, the working cylinder plunger 02 of hydraulic press in the prior art and the moved cross beam 06 of lower part are mostly
Flexural pivot connection, and connection is fixed by pressing sleeve 04 and differential 05.As shown in Fig. 2, the pressure that F1 generation table plunger 02 is downward, right side
Arrow represent the movement tendency of plunger 02, hydraulic press during the depression process, plunger 02 drives moved cross beam 06 to move downward,
In driving anvil block 07 to forging 08 carry out punching press, when hydraulic press after a period of work, between working cylinder cylinder body 01 and plunger 02
Continuous abrasion, causes fit clearance between the two excessive, therefore plunger 02 can generate shaking offset, thereby result in hydraulic press
06 connecting portion unbalance stress of two sides plunger 02 and moved cross beam in turn results in the connecting structure position stress of pressing sleeve and differential not
, fatigue failure is generated since stress is excessively concentrated, is damaged so as to cause pressing sleeve and differential.
Therefore, a kind of fatigue performance height how is provided, non-damageable connecting structure is that those skilled in the art need
The technical issues of solution.
Summary of the invention
In view of this, the purpose of the present invention is to provide a kind of fatigue performance height, non-damageable connecting structure.
Another object of the present invention, which also resides in, provides a kind of hydraulic press using above-mentioned connecting structure.
To achieve the above object, the invention provides the following technical scheme:
A kind of connecting structure, the differential including pressing sleeve and with pressing sleeve cooperation, the circumferential direction along the inner wall of the pressing sleeve are opened
Equipped with groove, the first groove face of the slot bottom of the groove and the groove is formed by angle and is set as arc angle, and described
The infall of the first end face of the side wall of differential and the differential is set as the curved end cooperated with the arc angle.
Preferably, the angle of the arc angle is between 30-45 degree, and the radian of the curved end is 30-45 degree
Between.
Preferably, the material of the pressing sleeve and the differential is carbon steel.
Preferably, the end face of the pressing sleeve is circumferentially arranged multiple through-holes passed through for bolt.
A kind of hydraulic press, including connecting structure, the connecting structure are connecting structure described in above-mentioned any one.
As can be seen from the above technical solutions, connecting structure disclosed by the invention, the pressure including pressing sleeve and with pressing sleeve cooperation
Orchid, opens up fluted along the circumferential direction of the inner wall of pressing sleeve, and the slot bottom of groove and the first groove face of groove are formed by angle and are set as
Arc angle, and the infall of the first end face of the side wall and differential of differential is set as the curved end cooperated with arc angle.
Self-regeneration is played in the offset of working cylinder cylinder body position caused by strenuous vibration when can be worked hydraulic press as arcuate structure
Effect, thus plunger can be reduced to the pressure of pressing sleeve and differential by adjusting the fit clearance between working cylinder cylinder body and plunger
Power plays apparent buffer function to the shaking offset of plunger, can further make the uniform force of pressing sleeve and differential, resistance to
Fatigue behaviour enhancing, works long hours and not easily leads to the damage of pressing sleeve and differential.
