Micro double-acting hydraulic press and forming method

Abstract

The invention discloses a miniature double-acting hydraulic machine and a forming method. The miniature double-acting hydraulic machine comprises an upper beam, a middle beam, a workbench, uprights, upper sleeves, lower sleeves, an upper oil cylinder, a lower oil cylinder, an upper piston rod connecting rod, a lower piston rod connecting rod and a guide sleeve. The upper beam and the workbench are connected through the four uprights. The middle beam is located through the upper sleeves and the lower sleeves, wherein the uprights are sleeved with the upper sleeves and the lower sleeves. The upper oil cylinder is fixed to the upper beam. The lower oil cylinder is fixed to the middle beam. The upper oil cylinder transmits power to a die through the upper piston rod connecting rod connected with the upper oil cylinder and the guide sleeve. The lower oil cylinder transmits power to the die directly through the lower piston rod connecting rod connected with the lower oil cylinder. The die is arranged on the workbench. The miniature double-acting hydraulic machine is tiny in size, stable in pressure, low in cost and capable of being matched with the miniature die to form a miniature part.

Description

technical field [0001] The invention relates to foil punching equipment, in particular to a miniature double-acting hydraulic press for stamping miniature parts. Background technique [0002] With the strengthening of the trend of product miniaturization, micro-forming technology has been paid more and more attention. At present, in products such as instruments, meters, and control components, the stamping of some metal miniature parts is mainly completed on existing ordinary presses. Stamping on ordinary presses has the disadvantages of energy waste and cost increase. At present, the die size is mainly increased by increasing the number of rows in the layout design to reduce energy waste. However, if the production batch is small or the forming rules of micro parts are studied in scientific research experiments, ordinary presses are not suitable. Existing small presses generally use manual or pneumatic stamping, but they are simple in structure, the pressure is not stable...

AI Technical Summary

Problems solved by technology

Stamping on ordinary presses has the disadvantages of energy waste and cost increase. At present, the die size is mainly increased by increasing the number of rows in the layout design to reduce energy waste.

However, if the production batch is small or the forming rules of micro-parts are studied in scientific research experiments, ordinary presses are not suitable.

Existing small presses generally use manual or pneumatic stamping, but they are simple in structure, the pressure is not stable, and they cannot complete the forming of complex miniature parts (such as micro blanking, deep drawing, composite forming, etc.)
