Description

Technical Field

[0001] The utility model relates to the technical field of press buffer tables, in particular to a buffer table for a servo press. Background Art

[0002] A servo press is a press controlled by a servo system. A press is a piece of industrial equipment typically used for processes such as machining, forming, stamping, and bending. A servo press incorporates a servo system to provide more precise, flexible, and efficient motion control. A servo press uses a servo motor or servo hydraulic system, which enables the machine to monitor and adjust motion parameters in real time, providing more precise position and force control. The buffer table is a crucial component of a servo press and plays a key role in the press's stamping process. The buffer table primarily assists the downward movement of the press by providing additional oil or pneumatic pressure to reduce the impact force between the upper and lower dies, protecting the die and improving the stability of the press.

[0003] After searching, the Chinese patent document with the announcement number: CN219903506U discloses a buffer table for a servo press, which specifically relates to the field of buffer tables, including a press body, a buffer table is slidably connected to the inside of the press body, a limiting cylinder is fixedly installed on the bottom of the buffer table, the limiting cylinder is slidably connected to the inside of the press body, a sliding rod is slidably connected to the inside of the limiting cylinder, a first limiting plate is fixedly installed on the outside of the slide rod, a tension spring is provided on the top of the first limiting plate, the tension spring is fixedly installed on the bottom of the buffer table, a second limiting plate is fixedly installed on the inner wall of the limiting cylinder, and the sliding rod is slidably connected to the inside of the second limiting plate. The utility model sets a slide bar and an elliptical column. The continuous descent of the pressure head will cause the slide bar to descend, and the elliptical column will descend synchronously with the slide bar.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figure 1 、 Figure 3 and Figure 4, the utility model provides an embodiment: a buffer table for a servo press, including a processing table 1, the upper part of the processing table 1 is fixedly connected to the mounting plate 2, the middle part of the mounting plate 2 is fixedly connected to a hydraulic cylinder 3, the output end of the hydraulic cylinder 3 is fixedly connected to a fixed block 4, a connecting column 11 is installed inside the fixed block 4, the bottom of the connecting column 11 is fixedly connected to a pressure head 12, the inside of the fixed block 4 is fixedly connected to mounting blocks 5, both sides of the inside of the fixed block 4 are fixedly connected, a connecting rod 7 is slidably connected inside the two mounting blocks 5, a handle 8 is fixedly connected to the top of the connecting rod 7, a rebound assembly is provided at the bottom of the connecting rod 7, a latch 9 is fixedly connected to the outside right side of the rebound assembly, the rebound assembly includes a slider 6, the slider 6 is fixedly connected to the bottom of the connecting rod 7, the slider 6 is slidably connected to the inside of the mounting block 5, a spring 26 is provided on the outside left side of the slider 6, a socket 10 is provided inside the connecting column 11, and the latch 9 is plugged into the socket 10.

[0025] By setting up the processing table 1, it is convenient to install the mounting plate 2. By starting the hydraulic cylinder 3, the fixed block 4 is moved, and the fixed block 4 is moved with the internally installed connecting column 11. The connecting column 11 carries the bottom fixed pressure head 12 to pressurize the workpiece. Then, when the pressure head 12 needs to be replaced, the slider 6 fixed at the bottom of the connecting rod 7 is moved by moving the handle 8, and the external fixed pin 9 is moved at the same time. When the slider 6 moves with the pin 9, the spring 26 set on the external left side is squeezed, so that the spring 26 is deformed under the force. Then the pin 9 is disengaged from the inside of the socket 10, and the pressure head 12 can be removed for replacement, which makes it easy to replace the pressure head 12 of the servo press, so that the servo press can adapt to workpieces of different sizes, shapes or materials, thereby improving the practicality of the servo press. The connection stability is improved by plugging the pin 9 into the socket 10.

[0026] Reference Figure 2 A damper 13 is fixedly connected to the middle part of the processing table 1, and a placement table 14 is fixedly connected to the output end of the damper 13. Fixed rods 15 are fixedly connected to both sides of the inside of the processing table 1, and moving blocks 16 are slidably connected to both sides of the outside of the two fixed rods 15. Connecting blocks 17 are fixedly connected to both sides of the upper part of the two moving blocks 16. Buffer rods 18 are rotatably connected to the inside of the two connecting blocks 17. Connecting blocks 19 are fixedly connected to the four sides of the lower part of the placement table 14. The other ends of multiple buffer rods 18 are rotatably connected to the inside of multiple connecting blocks 19. Springs 20 are sleeved on both sides of the outside of the two fixed rods 15.

[0027] By setting up a placement table 14, it is convenient to place the workpiece. When the placement table 14 is subjected to force, the buffer rod 18 rotating inside the connecting block 19 moves downward. At the same time, the buffer rod 18 moves to both sides outside the fixed rod 15 with the moving block 16 fixed at the bottom of the connecting block 17. When the moving block 16 moves, the spring 20 sleeved on the outside of the fixed rod 15 is squeezed, and the force generated is absorbed by the spring 20. Then, the damper 13 buffers the force generated when the workpiece is pressurized, thereby buffering the force generated when the workpiece is pressurized, reducing the impact on the workpiece and the pressure head 12, and improving the stability of the press.

[0028] Reference Figure 1 A controller 21 is installed on the right side of the upper part of the processing table 1, and a cabinet door 25 is provided on the front side of the outside of the processing table 1. A handle is fixedly connected to the front side of the outside of the cabinet door 25.

[0029] The controller 21 is provided to facilitate the control of the opening and closing of the hydraulic cylinder 3 , and the cabinet door 25 is provided to increase the storage function inside the processing table 1 .

[0030] Reference Figure 1 , both sides of the upper part of the placement table 14 are fixedly connected with fixed plates 22, the insides of the two fixed plates 22 are fixedly connected with electric push rods 23, and the output ends of the two electric push rods 23 are fixedly connected with positioning plates 24.

[0031] The fixing plate 22 is provided to facilitate the installation of the electric push rod 23. The positioning plate 24 fixedly connected to the output end is moved under the drive of the electric push rod 23. The workpiece is processed by the relative movement of the two positioning plates 24, which improves the stability of the workpiece during processing.

[0032] Working principle: When the ram 12 of the servo press needs to be replaced, the handle 8 is toggled, and the handle 8 moves with the connecting rod 7, and the connecting rod 7 moves with the slider 6 fixedly connected at the bottom, and the slider 6 moves with the pin 9 fixedly connected on the right side of the outside, and the movement of the slider 6 squeezes the spring 26 set on the left side of the outside, so that the spring 26 is deformed under the force, and then when the pin 9 is disengaged from the inside of the socket 10, the ram 12 can be removed for replacement, which makes it easy to replace the ram 12 of the servo press, so that the servo press can adapt to workpieces of different sizes, shapes or materials, and improves the practicality of the servo press. Then, the workpiece is placed on the surface of the placement table 14, and the ram 12 is started to pressurize the workpiece, and then the workpiece is pressed downward. At the same time, it moves the placement table 14 downward, and when the placement table 14 moves downward, it moves the connecting block 19 fixedly connected around the lower part downward, and the connecting block 19 moves downward, and moves the buffer rod 18 connected internally and rotates to move, and the buffer rod 18 moves and moves the connecting block 17 connected to the other end and rotates to move, and the connecting block 17 moves and moves the moving block 16 fixed at the lower part. When the two fixed rods 15 move outside, the moving block 16 moves to squeeze the spring 20 sleeved on the outside of the two fixed rods 15, and the force generated is absorbed by the spring 20, and then the damper 13 is used to buffer the force generated when the workpiece is pressurized, thereby buffering the force generated when the workpiece is pressurized, reducing the impact on the workpiece and the pressure head 12, and improving the stability of the press.
