The invention relates to a lower oil cylinder adjusting device of a multi-step multi-layer dry powder product full-automatic forming hydraulic machine. A lower oil cylinder is a double-output oil cylinder and comprises a powder sinking device, the powder sinking device comprises a powder sinking cylinder body, the powder sinking cylinder comprises a cylinder body, a piston head and a pressing cap,the cylinder body is arranged at the tail end of a lower output piston rod of the lower oil cylinder in a sleeving mode, the piston head is arranged in the cylinder body and sleeves the lower outputpiston rod of the lower oil cylinder, the piston head is correspondingly in sliding sealing contact with the cylinder body and the lower output piston rod of the lower oil cylinder, the pressing cap is arranged at the upper end of the cylinder body, the pressing cap is located above the piston head to form an upper limit of the piston head, a lower limit block and a lower adjusting seat are further arranged at the lower output piston rod of the lower oil cylinder in a sleeving mode, the lower limit lock and the lower adjusting seat are in sliding fit with the lower output piston rod of the lower oil cylinder, the lower limit block is supported on the lower adjusting seat, the lower adjusting seat is supported on the piston head, and the lower limit block forms an ejection limit of the lower oil cylinder. By means of powder sinking, splashing of thin-layer powder on the periphery of a female die opening caused when the upper die punch moves downwards is effectively prevented.
Description
technical field [0001] The invention relates to the technical field of forming dry powder products, in particular to a lower oil cylinder adjusting device of a multi-step multi-layer dry powder product fully automatic forming hydraulic machine. Background technique [0002] The fully automatic forming hydraulic press in the prior art, general structure is that the hydraulic press of three beams and four columns is equipped with multi-step formwork. And when the upper die punches down, the thin layer of powder around the female die mouth is splashed, which affects the uniform density of the product. [0003] Another example is the patent: CN201410444379.5 proposes a five-beam and four-column fully automatic multi-step powder product forming hydraulic press; also fails to solve the above problems. Contents of the invention [0004] The present invention proposes a multi-step and multi-layer dry powder product automatic molding hydraulic machine lower oil cylinder adjustment...
