Description

[0002] The electric screw press can be used for hot forging, precision forging and finishing; it can be applied to the pressure welding process of stainless steel clad bottom pots, and can also be applied to the precision forging of titanium alloy blades and other blades.

[0003] For example, an efficient and stable electric screw precision press with the authorization announcement number of "CN220073145U" drives the reducer to rotate through the motor in the efficient mechanism, the reducer drives the lead screw to rotate, the lead screw drives the lead screw nut to slide in the bottom box, and the two lead screw nuts drive the connecting block to move. The objects are precision pressed in sequence through multiple workbenches. When the object on one workbench is precision pressed, the other workbench is loaded and unloaded, reducing the downtime of the electric screw precision press body and improving the working efficiency of the electric screw precision press. However, the above does not have a safety height adjustment structure. Due to the unevenness of the external top surface, when the precision press works, the machine will shake, and the stress point will shift when the workpiece is precision pressed, which is likely to cause the workpiece to break, and the risk is relatively high. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem that due to the unevenness of the external top surface, when the precision press works, the machine will shake, and the stress point will shift when the workpiece is precision pressed, which is likely to cause the workpiece to break, and the risk is relatively high, and to propose an electric screw precision press with high safety.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] Design an electric screw precision press with high safety, including a top plate, multiple columns, and a frame. The lower surface of the top plate is fixedly connected to the upper surfaces of the multiple columns. A safety height adjustment structure is provided on the lower surfaces of the multiple columns. A safety electric screw precision pressing structure is provided in the groove processed on the surface of the top plate. The surface of the frame is threadedly connected to the external cement floor through two bolts. A third motor is fixedly connected to the surface of the frame through a bracket. The output shaft of the third motor is fixedly connected to a second threaded rod through a reducer. Both ends of the second threaded rod are rotatably connected to the inner wall of the frame through bearings.

[0007] Preferably, a plurality of the safety height adjustment structures include a first box body. The two ends of a worm are rotatably connected to the inner wall of the first box body through bearings. A handle is fixedly connected to the left end of the worm. The worm is meshed with a worm gear. The protruding part of the surface of the worm gear is rotatably connected to the inside of the first box body through a bearing. A first threaded rod is fixedly connected to the surface of the worm gear. The end of the first threaded rod is rotatably connected to the inner wall of the first box body through a bearing. The first threaded rod is threadedly connected to a threaded seat. The surface of the threaded seat is slidably connected to the slideways machined on both sides of the inner wall of the first box body. Two vertical rods are fixedly connected to the surface of the threaded seat. The two vertical rods penetrate through the first box body and are slidably connected to the first box body. The surfaces of the two vertical rods are fixedly connected to the surface of a cross plate.

[0008] Preferably, the lower surfaces of a plurality of the cross plates are in contact with the external ground, and anti-slip patterns are machined on the lower surfaces of the plurality of the cross plates.

[0009] Preferably, the upper surfaces of a plurality of the first box bodies are respectively fixedly connected to the lower surfaces of the columns, and the second threaded rod is threadedly connected to the two first squares.

[0010] Preferably, the safety electric screw precision pressing structure includes a hydraulic cylinder. The bottom of the hydraulic cylinder is fixedly connected to the inner wall of a groove machined on the surface of a top plate. A second square block is fixedly connected to the telescopic end of the hydraulic cylinder. Two straight rods are fixedly connected to both sides of the second square block. Rollers are installed at the ends of the two straight rods. Two vertical plates are fixedly connected to the lower surface of the top plate.

[0011] Preferably, the two first squares are slidably connected to the slideways machined on the inner wall of the frame through the protruding parts on their surfaces, and grooves are machined on the upper surfaces of the two first squares.

[0012] A highly safe electric screw precision press proposed by the present utility model has the beneficial effects that: through the cooperation of a safety height adjustment structure and a safety electric screw precision pressing structure, the handle drives the worm to rotate through a bearing in the first box body. The rotation of the worm drives the worm wheel to rotate through a bearing in the first box body. The rotation of the worm wheel drives the first threaded rod to rotate through a bearing in the first box body. The rotation of the first threaded rod drives the threaded seat to slide downward in the slideway machined on the inner wall of the first box body. The downward sliding of the threaded seat drives the two vertical rods to slide downward in the first box body. The downward sliding of the two vertical rods drives the cross plate to move downward. The hydraulic cylinder starts to drive the second square block to move downward. When the second square block moves, it will drive the cross bars on both sides to slide downward respectively in the chutes machined on the surfaces of the vertical plates through the rollers installed at the ends. Such movement can limit the moving position of the second square block and avoid deviation. Thus, the hydraulic cylinder also drives the second square block to perform precision pressing work on the workpiece. The safety height adjustment structure can jack up the defective position on the ground to avoid the deviation of the force application point of the workpiece caused by the shaking of the machine during the precision pressing work, which is likely to cause the workpiece to break, thereby improving the safety.

[0029] Working principle:

[0030] Safety screw precision pressing adjustment work:

[0031] When it is necessary to use the screw precision press to precision press the workpiece, turn the bolts on both sides of the frame 4 downward to connect with the external cement floor. Then, gently shake the top plate 3 to see if it shakes to judge whether the ground is flat. If it is found that the top plate 3 slides, turn the handle 103 at the defective position of the ground. The handle 103 drives the worm 102 to rotate in the first box body 101 through a bearing. The rotation of the worm 102 drives the worm gear 104 to rotate in the first box body 101 through a bearing. The rotation of the worm gear 104 drives the first threaded rod 105 to rotate in the first box body 101 through a bearing. The rotation of the first threaded rod 105 drives the threaded seat 106 to slide downward in the slideway machined on the inner wall of the first box body 101. The downward sliding of the threaded seat 106 drives the two vertical rods 107 to slide downward in the first box body 101. The downward sliding of the two vertical rods 107 drives the cross plate 108 to move downward. Such movement can adjust the defective position by jacking up to avoid shaking during precision pressing.

[0032] Safety screw precision pressing work:

[0033] After the top plate is fixed, the workpiece is placed in the grooves machined on the surfaces of the two first squares 5. Then, the external power supply of the third motor 6 is connected, and the third motor 6 starts to drive the second threaded rod 7 to rotate in the frame 4 through the bearing. The rotation of the second threaded rod 7 drives the two first squares 5 to move downward below the first squares 5. When the grooves machined on the surfaces of the front first squares 5 correspond to the first squares 5, the third motor 6 stops rotating. Subsequently, the external power supply of the hydraulic cylinder 2 is connected, and the hydraulic cylinder 2 starts to drive the second square 202 to move downward. When the second square 202 moves, it will drive the cross bars 203 on both sides to slide downward in the chutes machined on the surfaces of the vertical plates 204 respectively through the rollers installed at the ends. Such movement can limit the moving position of the second square 202 to avoid deviation. Thus, the hydraulic cylinder 201 also drives the second square 202 to perform fine pressing work on the workpiece. After the fine pressing is completed, the hydraulic cylinder 201 is controlled to drive the second square 202 to reset. Subsequently, the third motor 6 is controlled again to drive the second threaded rod 7 to rotate, so that the rear first square 5 corresponds to the second square 202, and then the subsequent fine pressing work is carried out in the same movement mode as above.
