Upper sliding block suppressing force display mechanism of powder make-up machine

Abstract

The invention relates to an upper sliding block suppressing force display mechanism of a powder make-up machine. The upper sliding block suppressing force display mechanism of the powder make-up machine is characterized by being arranged between an upper sliding block air cylinder plate and an upper connecting plate, comprising a hydraulic die cushion oil cylinder piston which is arranged on the lower portion of the upper sliding block air cylinder plate and a hydraulic die cushion oil chamber which is formed between the upper sliding block air cylinder plate and the hydraulic die cushion oil cylinder piston, and an upper air cylinder piston which is arranged on the lower portion of the hydraulic die cushion oil cylinder piston and connected with the upper connecting plate; and an upper air cylinder crash pad which is connected with the lower portion of the upper air cylinder piston is arranged on the lower portion of the upper air cylinder piston. The upper sliding block suppressing force display mechanism of the powder make-up machine adds a hydraulic die cushion pressure display mechanism which does not exist before, or is arranged on the lower position of a ball bowl piston, what is reflected is multiple aspect synthetic suppressing forces, after improvement, a placing position of the suppressing force display mechanism can authentically reflect the variable condition of die cavity suppressing force, namely real-time suppressing force is displayed, and so that timely adjustment by operating staff is convenient. In the meantime, the upper sliding block suppressing force display mechanism of the powder make-up machine can prevent a snap gauge from turning in a smothering mode and is convenient to turn reversely.

Description

technical field [0001] The invention relates to a sliding block pressing force display mechanism on a powder molding machine, which belongs to the technical field of powder metallurgy. Background technique [0002] The upper slider pressing mechanism is an important part of powder metallurgy, and its quality directly affects the quality of molded products. The existing upper slider pressing mechanism has the following defects: it cannot reflect the downward pressing force of the upper die, and cannot know The change of the pressing force in the mold cavity cannot timely adjust the size of the pressing force according to the actual situation of the product, which affects the molding quality of the product; and when the upper die is stuck in the female die, due to the existence of the upper pressing force, it is difficult to It is difficult to reverse the car to make the upper die punch out of the female die, and the forced out is easy to damage the mechanism and cause losses....
