[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4This utility model provides an embodiment: a multi-station adjustable hydraulic press for metal sheet forming, including a machine base 1, a mounting base 2 at the top of the machine base 1, and bases 3 fixed at the two sides and the middle of the top of the mounting base 2, hydraulic cylinders 13 fixedly installed on both sides inside the machine base 1, two sets of slots 15 arranged front and back on the two sides of the top of the machine base 1, two sets of sockets 16 fixed front and back on the two sides of the top of the mounting base 2, and several reserved holes 17 opened inside the sockets 16, several threaded inner holes 14 opened on the left side inside the slots 15, and two sets of positioning bolts 18 arranged front and back on the top of the two sides of the machine base 1.

[0022] The output ends of the two sets of hydraulic cylinders 13 pass through the interior of the top of the machine base 1 and are fixedly connected to the bottom of the mounting base 2. The slot 15 and the socket 16 are symmetrically arranged about the vertical center line of the machine base 1. Several reserved holes 17 are evenly distributed inside the socket 16. Several threaded inner holes 14 are evenly distributed inside the slot 15. The reserved holes 17 and the threaded inner holes 14 are connected. The left side of the positioning bolt 18 passes through the interior of the reserved hole 17 and is rotatably connected in the threaded inner hole 14.

[0023] Specifically, such as Figure 1 As shown, during the use of the hydraulic press, after unscrewing the four sets of positioning bolts 18 on both sides of the machine base 1 from the corresponding threaded inner holes 14 inside the slot 15, the output end of the hydraulic cylinder 2 13 can be extended by controlling the hydraulic cylinder 2 13 to push the mounting base 2 upwards, raising and adjusting the operating height of the top of the hydraulic press. After adjustment, the positioning bolts 18 on both sides of the machine base 1 are inserted into the pre-drilled holes 17 at different positions and rotated to lock them in the threaded inner holes 14 at the corresponding height positions. This locks the position of the mounting base 2 on the top of the machine base 1, preventing the hydraulic cylinder 2 13 from depressurizing and facilitating flexible adjustment of the operating height of the hydraulic press.

[0024] The base 3 has an inner groove 12 at its top, and a movable platform 11 is set inside the inner groove 12. A lower mold 10 is fixedly installed at the bottom of the movable platform 11. A lead screw 23 is movably connected to the bottom of the inner groove 12, and a threaded sleeve 22 is threadedly connected to the outside of the lead screw 23. A servo motor 21 is fixedly installed at the rear end of the base 3. Slide grooves 20 are respectively set on both sides of the bottom of the inner groove 12. Slider blocks 19 are respectively fixed on both sides of the bottom of the movable platform 11. The output shaft of the servo motor 21 is fixedly connected to the rear end of the lead screw 23. The top of the threaded sleeve 22 is fixedly connected to the rear end of the top of the movable platform 11. The slider 19 is slidably connected in the slide groove 20.

[0025] Specifically, such as Figures 1-3As shown, when forming a metal sheet workpiece, the servo motor 21 can be controlled to start the drive screw 23 to rotate. When the screw 23 rotates, the threaded sleeve 22 can drive the movable table 11 to move forward inside the inner groove 12. At the same time, the lower die 10 can be pushed outward from the bottom area of ​​the upper die 6. By loading and unloading the metal sheet outside the stamping area, the safety of the hydraulic press loading operation is improved.

[0026] A fixing cover 8 is fixed to the outer side of the top of the mounting base 2, and a cover plate 26 is provided on both sides of the front end of the fixing cover 8. A fixing frame 24 is fixed to the top and bottom of the front ends of both sides of the fixing cover 8. A fixing foot 25 is fixed to the top and bottom of the left side of the cover plate 26. The fixing foot 25 is hinged to the inside of the fixing frame 24. A fixing sleeve 27 is fixed to the right side of the front end of the left cover plate 26 and the left side of the front end of the right cover plate 26. A pin 28 is inserted into the inside of the two sets of fixing sleeves 27. A handle is fixed to the front end of the cover plate 26.

[0027] Specifically, such as Figure 1 and Figure 4 As shown, by providing a fixed cover 8 and a cover plate 26 on the outer side of the top, auxiliary outer protection against impact can be provided for the outside of the hydraulic press assembly. When using the hydraulic press, the pin 28 is pulled out from inside the fixed sleeve 27 at the front end of the cover plate 26, and then the cover plate 26 is flipped outward to expose the front end area of ​​the hydraulic press.

[0028] The top of the base 3 is provided with a top seat 7, and the bottom of the top seat 7 is provided with a movable seat 5. Guide posts 4 are fixed on both sides of the top of the base 3, and the top of the guide posts 4 penetrates the interior of the movable seat 5 and is fixedly connected to the bottom of the top seat 7. A hydraulic cylinder 9 is installed and fixed on the top of the top seat 7, and the output end of the hydraulic cylinder 9 penetrates the interior of the top seat 7 and is fixedly connected to the top of the movable seat 5. An upper pressure mold 6 is installed and fixed on the bottom of the movable seat 5.

[0029] Working Principle: During the operation of the hydraulic press, when loading and unloading metal sheet workpieces, the servo motor 21 can be controlled to start and drive the lead screw 23 to rotate. Simultaneously, the screw 23 rotates, and the threaded sleeve 22 drives the movable table 11 to move forward inside the inner groove 12. At the same time, the lower die 10 can be pushed outward from the bottom area of ​​the upper die 6. By loading and unloading metal sheets outside the stamping area, the safety of the hydraulic press during loading is improved. After the metal sheet is loaded to the top of the lower die 10, the hydraulic cylinder 9 is controlled to start and drive the movable seat 5 and the upper die 6 to move downward, thus stamping and forming the metal sheet. During operation of the hydraulic press, after unscrewing the four sets of positioning bolts 18 on both sides of the machine base 1 from the corresponding threaded inner holes 14 inside the slots 15, the output end of the hydraulic cylinder 2 13 can be extended to push the mounting base 2 upwards, raising and adjusting the operating height of the top of the hydraulic press. After adjustment, the positioning bolts 18 on both sides of the machine base 1 are inserted into the corresponding pre-drilled holes 17 and rotated to lock them into the threaded inner holes 14 at the corresponding height positions, thus locking the position of the mounting base 2 on the top of the machine base 1 and flexibly adjusting the operating height of the hydraulic press. Furthermore, during operation, the fixed cover 8 and cover plate 26 on the outer side of the top provide auxiliary external protection against impact to the hydraulic press components. The two sets of openable and closable cover plates 26 at the front ensure the normal operation of the hydraulic press.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
