Vibration molding machineof film type hydraulic vibration exciter

Abstract

The invention provides a vibration molding machineof a film type hydraulic vibration exciter. The vibration molding machineof the film type hydraulic vibration exciter comprises a rack, a lifting device, and an upper balance weight, an upper mold, a lower mold, a tabletop, a film type hydraulic vibration exciter and a lower balance weight which are sequentially arranged from top to bottom, wherein the lifting device is mounted atthe upper part of the rack; the film type hydraulic vibration exciter comprises a film made of a soft material, a rigid flat plate I and a rigid flat plate II which are parallel to each other; the film is arranged between the rigid flat plate I and the rigid flat plate II; the film independently forms a sealed space for containing liquid or the film, the rigid flat plate I and the rigid flat plate II jointly form the sealed space for containing the liquid; the sealed space is communicated with a hydraulic source capable of outputting liquid flow with a periodically-changed direction by virtue of a channel. The vibration molding machineof the film type hydraulic vibration exciter is simple to manufacture, convenient to maintain, stepless in frequency modulation and amplitude modulation without halt, irrelevant in frequency modulation and amplitude modulation, low in cost, strong in vibration, free of abrasion, free of leakage, free of heat dissipation, uniform in distribution of vibration force and low in energy consumption; the interference on the outside vibration force is almost equal to 0.

Description

technical field [0001] The invention relates to a thin-film hydraulic vibration exciter vibration forming machine, which belongs to the field of vibration machinery. Background technique [0002] Existing vibration molding machines work with centrifugal vibrator, and its shortcoming is: when vibrating force is big, and frequency is high, one or two vibrator can't be competent. In this way, multiple exciters have to be used in parallel, because all the vibration forces must act on the bearings, so the lubrication, heat dissipation, sealing, and transmission between the shafts of the bearings become very complicated, which brings great difficulties to manufacturing, installation, and maintenance. There are many problems, and the reliability is also reduced. [0003] In addition, a shutdown is necessary to adjust the amplitude of the machine. Furthermore, the vibration force of the mechanical exciter is concentrated and cannot be evenly distributed, which makes the struct...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a vibration molding machine with a film hydraulic exciter, which can be continuously modulated with frequency and amplitude without stopping, low in cost, large in vibration force, no wear, no leakage, no need for heat dissipation, uniform distribution of vibration force, and low energy consumption. The vibration force interference to the outside world is almost equal to 0, which solves the above-mentioned problems existing in the existing vibration molding machine
