Pressing principle and mechanism of powder pressing machine special for 5G ceramic filter forming

Abstract

The invention relates to a pressing principle and mechanism of a powder pressing machine special for 5G ceramic filter forming. A pressing structure comprises an eccentric cam, a first connecting rod, a lever, a pull rod, an upper crank, a second connecting rod and an upper punching seat, wherein the eccentric cam is arranged at the bottom of the pressing mechanism, connected with an external motor and a speed reducer and driven by the external motor and the speed reducer to rotate anticlockwise, the upper part of the eccentric cam is connected with the first connecting rod, and the upper part of the first connecting rod is connected with the lever; and one end of the lever is connected with the lower end of the pull rod, the upper end of the pull rod is connected with the upper crank, the second connecting rod is arranged below the upper crank and connected with the upper crank, and the upper punching seat is arranged below the second connecting rod and connected with the second connecting rod. Through the design of a whole machine pressing forming toggle rod mechanism, the eccentric cam special for 5G and a demolding cam, the functions of large pressing interval and long pressure maintaining time required for forming a 5G ceramic filter are achieved.

Description

technical field [0001] The invention relates to a powder forming machine, in particular to a pressing principle and mechanism of a powder pressing machine specially used for forming 5G ceramic filters. Background technique [0002] At present, most of the existing powder compaction molding machines have complex structures, high energy consumption, low energy utilization rate, high work cost, short pressurization process time, and insufficient pressure holding time to meet the high density of each step after forming. Uniformity requirements, after pressing and forming 5G ceramic filter products, the elastic aftereffect is large, the dimensional accuracy is poor, and the pass rate is low. Contents of the invention [0003] The purpose of the present invention is to provide a pressing principle and mechanism of a powder press specially used for forming 5G ceramic filters, so as to solve the problems in the prior art. [0004] The technical solution of the present invention i...
