The invention discloses a fast device for a medium-large hydraulic metal filing briquetting machine. The fast device comprises a cylinder barrel (3), a guide bushing (2), a cylinder tail (7), a built-in piston rod (4), a built-in piston (5) and a main piston rod (1) which is capable of moving in the cylinder barrel (3), wherein at least one penetrating purge oil supplementing port A communicatingwith the interior of the cylinder barrel (3) is formed in the cylinder tail (7), a built-in oil cylinder oil port B capable of penetrating the cylinder tail (7) and the built-in piston rod (4) and communicating with a cavity in the main piston rod (1) is additionally formed in the cylinder tail (7), a rod cavity retreat oil port D is formed in the side surface of the front end of the cylinder barrel (3), and a rodless cavity pressurizing oil port C communicating with the interior of the cylinder barrel (3) is further formed in the cylinder tail (7). The interior of the main piston rod is designed into a small oil cylinder cavity, the built-in piston rod is mounted in the small oil cylinder cavity of the main piston rod, therefore, coaxial precision is guaranteed, and equipment durability is improved greatly.
Description
technical field [0001] The invention belongs to the field of medium and large hydraulic metal chip briquetting machines, in particular to a quick device for medium and large hydraulic metal chip briquetting machines. Background technique [0002] The hydraulic metal shavings briquetting machine is widely used in the field of scrap metal recycling. It is suitable for pressing scrap steel (cast iron) scraps, scrap aluminum scraps, scrap copper scraps, and other granular and loose materials into small volumes and high densities for easy transportation. Or stored cakes, but also a very efficient furnace concentrate. [0003] At present, the fast device of this equipment in China basically adopts a structure in which an external small oil cylinder is connected in series with the main piston to achieve the purpose of fast work. The disadvantages of this structure are large axial size, low coaxial precision, low durability, high material and manufacturing costs, and poor economy, ...
