Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1

Referring to fig. 1-3, a hydraulic press with a buffer mechanism comprises a hydraulic press body 1 and a base 4, wherein the base 4 is located below the hydraulic press body 1, a pressure reducing pad 9 is compositely bonded at the lower end of the base 4, and the pressure reducing pad 9 can avoid the lower end of the base 4 from directly contacting with the ground, so that the abrasion to the base 4 is reduced.

A plurality of positioning columns 6 are vertically welded between the outer side of the lower end of the hydraulic machine body 1 and the outer side of the upper end of the base 4, a supporting table 2 is arranged between the outer sides of the positioning columns 6 in a sliding manner, the supporting table 2 is positioned between the base 4 and the hydraulic machine body 1, a disc 5 is fixed in the middle of the lower end of the supporting table 2 through bolts, a plurality of groups of damping mechanisms 3 are uniformly arranged between the lower end surface of the disc 5 and the base 4, and the plurality of groups of damping mechanisms 3 are distributed on the upper end surface of the base; the damping mechanism 3 comprises a square groove 35 arranged on one side of the upper end of the base 4 and a connecting rod 31 hinged on the outer side of the lower end of the disc 5, a sliding block 32 is arranged in the square groove 35 in a sliding mode, the square groove 35 is in clearance fit with the sliding block 32, the upper end of the sliding block 32 is hinged on the lower end of the connecting rod 31 through a hinged seat, a round rod 33 is horizontally fixed in the middle of the inner side of the square groove 35, the sliding block 32 is arranged on the outer side of the round rod 33 in a sliding mode, a return spring 34 is sleeved on the outer side of the round rod 33, the return spring 34 is located on one side far away from the connecting rod 31, after a hydraulic head of the hydraulic machine body 1 is in contact with an object placed in the middle of the upper end of the supporting table 2, downward pressure of the hydraulic head can drive the supporting table 2 to move downwards, in the downward process of the supporting table 2, the sliding block 32 located in the, realize the absorbing effect of buffering, the hydraulic pressure head is to the article punching press back simultaneously, upwards lifting to the pressure of hydraulic pressure head to a supporting bench 2 upper end is removed, and slider 32 moves to the one end that is close to connecting rod 31 this moment under the tensile influence of reset spring 34, thereby highly realizes the lifting with a position of a supporting bench 2.
