[0021] 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.

[0022] like Figures 1 to 4 As shown, this utility model provides a press, including a top plate 1, a bottom plate 2, and a support column 3 disposed between the top plate 1 and the bottom plate 2. A pressure plate 4 is also provided between the top plate 1 and the bottom plate 2. The top plate 1 is provided with a driving assembly 5 for driving the pressure plate 4 to move between the top plate 1 and the bottom plate 2. The press forms a frame through the top plate, the bottom plate, and the support column. The driving assembly mounted on the top plate drives the pressure plate up and down to realize the operation of the press.

[0023] In this design, the drive assembly 5 includes a drive motor 51 mounted on the top plate 1, a transmission assembly 52, and a first transmission screw 531 and a second transmission screw 532 located between the top plate 1 and the bottom plate 2. The pressure plate 4 is driven by the first transmission screw 531 and the second transmission screw 532, which are spaced apart on both sides of the pressure plate 4. The overall structure is simple, the device is more compact, and this design utilizes a double-screw drive to move the pressure plate, resulting in more even force distribution and smoother operation of the pressure plate during operation, thus avoiding pressure plate failure due to uneven force distribution after long-term use.

[0024] In this embodiment of the present invention, the first transmission screw 531 and the second transmission screw 532 can be located on the outside of the pressure plate 4. Preferably, for the purpose of miniaturization, the first transmission screw 531 and the second transmission screw 532 are located inside the pressure plate 4 and close to both sides of the pressure plate 4. The middle part of the pressure plate 4 is also provided with a mounting part 401 for assembling the pressure head. The first transmission screw 531, the second transmission screw 532 and the mounting part 401 are arranged collinearly.

[0025] Correspondingly, this solution has an installation position on the base plate 2, which is used to install tooling workpieces to facilitate alignment with the pressure head on the pressure plate 4.

[0026] Furthermore, to ensure more stable transmission, the pressure plate 4 in this design is equipped with transmission sleeves 41 on both sides. The transmission sleeves 41 on both sides allow the first transmission screw 531 and the second transmission screw 532 to pass through, respectively. Additionally, the transmission sleeves 41 are detachably connected to the pressure plate 4, allowing for individual replacement of the transmission sleeves 41 after wear from long-term operation. Moreover, when the pressure plate becomes unbalanced, one side of the transmission sleeve 41 can be adjusted, providing greater flexibility compared to the traditional single-screw method.

[0027] Furthermore, in this embodiment of the invention, the support columns 3 include at least four columns, and the four support columns 3 are distributed at four corners. Moreover, the pressure plate 4 in this solution also utilizes the four support columns 3 to make the upward or downward pressing process more stable. The pressure plate 4 is also provided with through holes corresponding to the positions of the support columns 3 and allowing the support columns 3 to pass through. A guide sleeve 42 fitted onto the support column 3 is also provided in the through holes. Furthermore, the four support columns 3 on the pressure plate 4 are also distributed at four corners, similarly located outside the first transmission screw 531 and the second transmission screw 532, serving to assist in force reception and guidance.

[0028] Furthermore, a detection component 8 is provided on one side of the top plate 1 in this solution, and a detection arm 48 is provided on the side of the pressure plate 4 located at the detection component 8. The detection arm 48 extends upward and can approach the detection component 8 as it moves upward with the pressure plate 4. Through this simple structure, the upper limit of the pressure plate 4 can be automatically stopped. The detection component 8 can be a photoelectric sensor. When the upper end of the detection arm 48 extends into the detection position of the detection component 8, it can be determined that the upper limit has been reached, and the drive motor will stop.

[0029] Furthermore, this solution uses a single drive motor to synchronously drive the first transmission screw 531 and the second transmission screw 532, ensuring the synchronization of the transmission and improving smoothness. The drive motor 51 in this solution is also equipped with an adjusting plate 54, which is connected to the top plate 1. The output end of the drive motor 51 extends from the adjusting plate 54. The transmission assembly 52 includes transmission pulleys located on the first transmission screw 531 and the second transmission screw 532. The drive motor 51 is connected to the transmission pulleys of the first transmission screw 531 and the second transmission screw 532 via a synchronous belt 521. Additionally, the drive motor 51 is mounted via the adjusting plate 54, making assembly quicker and easier. The adjusting plate 54 is equipped with an adjusting elongated hole 541. By adjusting the mounting position of the adjusting plate 54 and the top plate 1, the distance between the output end of the drive motor 51 and the transmission assembly 52 can be changed, thereby facilitating the installation and tightening of the synchronous belt 521. Furthermore, the adjusting plate 54 described in this solution is also equipped with a pressure wheel 542, which facilitates further adjustment of the tension of the synchronous belt 521 to achieve synchronous transmission.

[0030] This utility model provides a press, which forms a frame with a top plate, a bottom plate and a support column. The press operates by using a drive assembly installed on the top plate to drive the pressure plate up and down. The overall structure is simple and the device is more compact. Moreover, this solution uses a drive method of double lead screws to move the pressure plate, which makes the pressure plate more evenly stressed and runs more smoothly during operation, avoiding the problem of pressure plate failure due to uneven stress after long-term use.
