[0006] The present application provides a metal processing press machine adopting the following technical solution:

[0007] A metal processing press, comprising:

[0008] A placing table, wherein a pressure plate is connected to the placing table;

[0009] A fixed plate, the fixed plate is located above the placement table, and a plurality of supporting columns are connected between the fixed plate and the placement table, and the pressure plate is located in a cavity surrounded by the plurality of supporting columns;

[0010] A lower pressing plate, the lower pressing plate is located between the fixing plate and the pressure plate, and a metal processing space is formed between the lower pressing plate and the pressure plate;

[0014] By adopting the above technical scheme, the operator places the metal to be processed on the pressure plate. At this time, the metal to be processed is located in the metal processing space. The driving unit works to make the lower pressure plate move toward one side of the pressure plate. While the lower pressure plate descends, force is applied to the protective cover through the linkage cable. After the fixed plate is reversed, the lower pressure plate is pressed down while the protective cover rises, so that the protective cover can form a shielding space when the metal is pressurized. The designed metal processing press machine is convenient for installing and supporting the pressure plate through the placement table, and convenient for cooperating with the supporting columns to form a height range for metal pressure processing through the fixed plate. The metal pressure processing is convenient to complete through the lower pressure plate and the driving unit.

[0020] An adjusting nut is threadedly connected to the reduced diameter section, and a top wall of the adjusting nut abuts against the connecting section.

[0021] By adopting the above technical solution, the designed support frame can fix the reduced diameter section through the fixed section, the reduced diameter section can cooperate with the connecting section to realize the sliding of the connecting section, the connecting section can be raised and lowered by adjusting the nut, and the initial position of the protective cover can be adjusted by adjusting the position of the positioning wheel.

[0022] In a specific possible implementation manner, the axial directions of the plurality of support columns are consistent, the support columns are arranged through the lower pressing plate, and the lower pressing plate is slidably connected to the support columns.

[0023] By adopting the above technical solution, a lower pressing plate designed to be slidably connected to the supporting column can ensure the consistency of the movement direction of the lower pressing plate and improve the force stability of the edge area of ​​the lower pressing plate.

[0024] In a specific possible implementation scheme, the driving unit includes a hydraulic press, which is connected to the fixed plate, a piston rod of the hydraulic press passes through the fixed plate and is connected to the lower pressure plate, and the piston rod of the hydraulic press is staggered with the fixed plate.

[0025] By adopting the above technical solution, the designed driving unit can drive the lower pressure plate to rise and fall through the hydraulic press.

[0026] In a specific possible implementation manner, the protective cover is made of a transparent material.

[0027] By adopting the above technical solution, the protective cover made of transparent material can realize the protective function and facilitate the operator to observe the pressure processing state of the metal.

[0028] In a specific possible implementation manner, a plurality of abutment wheels are rotatably connected to the inner side wall of the protective cover, and the abutment wheels are rollingly connected to the placement table.

[0029] By adopting the above technical solution, the sliding friction between the inner wall of the protective cover and the outer peripheral side of the placement table can be replaced, thereby reducing the possibility that the transparent material protective cover is scratched during the lifting process, resulting in a decrease in transparency.

[0030] In a specific possible implementation manner, at least one return spring is connected to one end of the protective cover away from the linkage cable, and the return spring is connected to the placement platform to move the protective cover toward a side away from the fixed plate.

[0031] By adopting the above technical solution and designing the return spring, the integrity of the lifting and lowering movement of the protective cover can be improved.

[0032] In summary, the present application includes at least one of the following beneficial technical effects:
