[0002] A servo press is a high-precision device that uses a servo motor as its power source and converts the motor's rotational motion into linear reciprocating motion of a slider through a precision transmission mechanism, achieving press processing.

[0037] By adopting the above solution, after the auxiliary support components 12 are arranged opposite to each other on the left and right sides, the placement plate 6 can be restricted when it moves downward, thereby avoiding the placement plate 6 from shaking when moving.

[0038] refer to Figure 1 and Figure 6 The bottom of the buffer table 4 is fixedly connected with a positioning column 13, and a slot 14 is opened at the position corresponding to the positioning column 13 on the top of the workbench 2, and the positioning column 13 is plugged into the inside of the slot 14, and the inside of the slide groove 3 is slidably connected with a mounting seat 15, and the bottom of the buffer table 4 is fixedly connected with a plug-in column 16 at the position corresponding to the mounting seat 15, and the plug-in column 16 is plugged into the top of the mounting seat 15.

[0040] Working principle of the present invention: When in use, the buffer table 4 is assembled with the slot 14 and the mounting seat 15 on the top of the workbench 2 through the positioning column 13 and the plug-in column 16. The pressure generated by the press 1 during operation can be buffered by the use of the buffer table 4. First, the placement plate 6 moves downward after being pressurized, and then the placement plate 6 drives the extrusion block 805 to move downward. When the extrusion block 805 moves, it squeezes the inclined hole 804 on the surface of the transmission frame 803, and then drives the transmission frame 803 to move. When the transmission frame 803 moves, it drives the inclined block 802 to move, and then the pressure can be reduced by The movement of the inclined block 802 squeezes the buffer cylinder 801, thereby buffering the movement of the placement plate 6. Then, the placement plate 6 will drive the connecting block 1204 to move downward when it moves. The connecting block 1204 can drive the pushing column 1205 to move when it moves. Then, the pushing column 1205 squeezes the inner wall of the transmission hole 1203 on the surface of the swing rod 1202, so that the swing rod 1202 can rotate around the base block 1201 through the rotating shaft, thereby limiting the movement of the placement plate 6 and improving the stability of the placement plate 6 when it moves.

[0041] To sum up: the buffer table for the servo press solves the problem that the buffer table often lacks a structure to fully support the core components of the workpiece, which will cause the four corners of the placement plate to be unevenly stressed when subjected to force, and is prone to tilting, by setting up a press 1, a workbench 2, a slide 3, a buffer table 4, a cavity 5, a placement plate 6, a support assembly 7, a buffer structure 8, an extension plate 9, a second spring 10, a first limiting column 11, an auxiliary support assembly 12, a positioning column 13, a slot 14, a mounting seat 15 and a plug-in column 16.
