[0002] With the continuous development of society, people's living standards have improved rapidly. At the same time, industry is also constantly improving. When processing and manufacturing parts, an open fixed-table press is needed to apply strong pressure to the metal blank to cause plastic deformation and fracture of the metal to process it into parts. The existing devices of this type are not convenient for fixing and limiting the workpiece to be processed, and are prone to deviation or displacement during stamping, affecting the processing accuracy and quality of the workpiece. Because the stamping process causes the stamped parts to deform and expand outward, the area will expand. If the fixed structure cannot change its fixed position under fixation, it is very easy to generate a strong impact force on the fixed structure under stamping, causing the fixed structure to be damaged by the impact force.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0019] Reference Figure 1-4 , a high-safety open fixed-table press, comprising a frame 1, a hydraulic cylinder 2, a stamping seat 3, a stamping table 5 and a limit fixing assembly, the frame 1 is a square frame, the frame 1 is equipped with a downwardly arranged hydraulic cylinder 2 at the top of the frame, the stamping seat 3 is installed at the end of the telescopic shaft of the hydraulic cylinder 2, a limit plate 31 extending outward is arranged around the stamping seat 3, and the four corners of the limit plate 31 are movably penetrated by a limit rod 4, a stamping table 5 is arranged at the bottom of the frame 1, the bottom end of the limit rod 4 is fixed on the stamping table 5, and the top end is fixed by a mounting rod arranged on the side wall inside the frame 1, and two groups of limit fixing assemblies 6 are symmetrically arranged on the upper surface of the stamping table 5, each group of the limit fixing assemblies 6 includes a long strip mounting block 7 and a plurality of adjustment fixings arranged at equal intervals on the long strip mounting block 7, and the adjustment fixings on the two long strip mounting blocks 7 are symmetrically distributed.

[0020] During stamping, first place the stamping part on the stamping table 5, start the synchronous movement of the adjusting fixing part through the operation panel of the press, squeeze and fix the two sides of the stamping part, so that the stamping part is in the middle position of the stamping table 5, and start stamping. During the stamping process, the limit plate 31 is limited by four limit columns and can only slide up and down, so as to ensure that the stamping seat 3 does not deviate from the up and down movement. Ensure the stability of stamping. Since each adjusting fixing part has an elastic fixing function, that is, when fixed, when subjected to an outward support force, the side of the fixed stamping part that the adjusting fixing part will deform accordingly will not be damaged due to deformation during stamping.

[0021] After the stamping is completed, the stamping seat 3 is moved upward, and the fixing of the adjusting fixture is loosened, the stamped part is taken away, and the next stamped part is waited for stamping.

[0022] The punching seat 3 has a hemispherical protrusion 30 above the limiting plate and a square columnar punching column below the limiting plate 31 .

[0023] The hemispherical protrusion 30 is used to install the telescopic shaft of the hydraulic cylinder 2. The telescopic shaft is inserted into the center of the hemispherical protrusion 30 to ensure that the hemispherical protrusion 30 is evenly stressed and spreads to the surroundings, ensuring that the downward pressure of the entire stamping seat 3 is uniform. The square columnar stamping column can be stamped using a stamping part.

[0024] The adjusting fixing part includes a square sleeve 64, an extrusion spring 65, an extrusion rod 66, a push rod 63, a screw 62 and a motor 61. The square sleeve 64 is plugged with an extrusion spring 65, the front end of the square sleeve 64 is inserted with an extrusion rod 66 and the front end of the extrusion rod 66 is provided with an extrusion plate 661, the rear end of the square sleeve 64 is inserted with a push rod 63, the two ends of the extrusion spring 65 are respectively fixedly connected to the ends of the extrusion rod 66 and the push rod 63, one end of the screw 62 is spirally inserted from the other end of the push rod 63, and the other end of the screw 62 is connected to the rotating shaft of the motor 61.

[0025] The motor 61 drives the screw rod 62 to rotate, and the screw rod 62 pushes the push rod 63 to move, thereby squeezing the extrusion spring 65. The extrusion spring 65 then pushes the extrusion rod 66 outward, causing the extrusion rod 66 to extend, so that the extrusion plate 661 squeezes the side of the stamping part to fix the two sides of the stamping part, and the extrusion spring 65 has a buffering effect. When the stamping part is deformed, it will be supported outward, causing the extrusion spring 65 to further deform, but it will not damage the adjusting fixing part, and can continue to fix the side of the stamping part.

[0026] The maximum distance between the extrusion plates 661 on the two groups of the position limiting and fixing components 6 is greater than the width of the punching seat 3, so as to ensure that the punching parts with the same width as the punching seat can be fixed.

[0027] The number of adjusting fixing parts in the position limiting fixing assembly 6 is not less than 4. More than 4 extrusion plates can be used to extrusion fix the side of the stamping part, and the side is not on one side, and more than four extrusion plates 661 can better adapt to the side fixation.

[0028] The width of the adjustment fixing parts in each group of the position limiting fixing assembly 6 is greater than the front-to-back width of the punching seat 3. The side of the punching part can be fixed so that the front-to-back width of the punching part is the same as the front-to-back width of the punching seat.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
