Problems solved by technology

Due to impacts under the pallet, the vibration table always changes its tilted position, so the mechanical load of the exciter actuator acting as a linear guide is high
Especially when there are two linear guides, the mechanical load is increased due to the tendency of the guides to jam
[0013] The compacting device described in the EP 0870585 communique cannot be used as a mold for imitation due to the following reasons: the system spring realized in a hydraulic manner only acts as a spring when it vibrates downward; and for the hydraulic exciter Using the same fluid medium as the hydraulic spring will cause a large energy loss when acting as a spring

Embodiment Construction

[0035] figure 1 Among them, reference numeral 100 denotes the frame of the compacting device standing on the base 102, through which the forces transmitted from the compressing device 104 and from the vibrator device 106 are mutually supported. In this case, the frame is firmly connected to the base by a connection indicated by line 190 . When the mass of the frame is small, the exciting force transmitted to the base is quite large. The lower end of the molded body 110 enclosed in the molding cavity of the molding box 108 is placed on the pallet 112 . The pallet rests on a bar 114 which is secured to the frame 100 (hatched for clarity) with a gap 116 . The impact rod 118 of the vibrating table 120 can pass through this gap and impact the underside of the pallet after overcoming the air gap 122 during the vibrating motion of the vibrating table. The molding box 108 placed on the pallet is firmly pressed against the upper surface of the pallet 112 by the spring 124 supported...

Abstract

Apparatus and method for carrying out compaction operations on molded bodies, the compaction being achieved by impact of a vibrating table on the underside of the pallet. The vibrating table, together with a spring system forms a mass-spring system, which acts as a vibrator capable of oscillation that is excited by an excitation device to produce forced vibrations. The spring system, together with the system mass, is designed to develop at least one individual frequency within the range of the compaction frequency, whereby it is also possible to adjust the individual frequency gradually or continuously. This, together with the fact that the excitation frequency can be adjusted, allows the vibrator to be operated partially or completely in resonance mode over the whole frequency range of the compaction.

Description

technical field [0001] The present invention relates to a compacting device, operating in vibration, for molding and compacting molding material in a molding cavity in a molding box to form a molded body; it also relates to a method of using the compacting device. The molded body has upper and lower ends to which compaction forces can be applied. Where this method is used, the molding material is initially placed in the molding cavity as a bulk of loose, cohesive granular components prior to the compaction work. During the compaction work, the loose granular material is molded into a dense molded body by the action of the compaction force above and below. When compaction devices are used in machines for the manufacture of concrete products such as paving blocks, the loose, cohesive mass of granular material may consist of wet concrete mortar. In the case of compaction devices with vibrators for the manufacture of final concrete products, three known common forms of compactio...
