Description

[Detailed Description of the Invention] The present invention is designed to connect mechanical devices such as presses and hammers, liquid storage tanks, etc. and their installation bases or
This invention relates to a vibration isolating mat device that is inserted between heavy walls to buffer transmitted shock and absorb vibration.

Conventionally, such anti-vibration mats have been heat resistant and/or
Alternatively, flat elastic mats made of oil-resistant synthetic resin or rubber have been used, but they have the disadvantage that they do not exhibit sufficient elasticity when the supporting load becomes large, and they also have a relatively short lifespan.

An object of the present invention is to provide a vibration-isolating mat device that exhibits sufficient elasticity even under large supporting loads and has a long lifespan that can effectively absorb vibrations.

According to the present invention, in order to achieve this purpose,
A flat reinforced elastic mat made of heat-resistant and/or oil-resistant synthetic resin or rubber is provided, in which at least two coil springs having an outer diameter substantially equal to the thickness of the mat are arranged along the axis of the mat. The planar reinforced elastic pine is buried in the pine parallel to the surface, and has an outer peripheral protruding edge protruding from both mat surfaces of the planar reinforced elastic pine, and the planar reinforced elastic pine is sandwiched between rigid support plates from both sides in a sandwich-like manner. With this structure, load-bearing force is transmitted uniformly over the entire surface of the flat reinforced elastic pine, and by uniformly elastically deforming each coil spring in the diametrical direction, vibration is uniformly generated. By performing absorption and shock-absorbing functions, it is possible to produce large vibration-absorbing and shock-absorbing functions as a whole, and to significantly extend the service life.

The present invention will be explained below with reference to the drawings.

In the drawings, reference numeral 1 indicates a flat reinforced elastic mat made of heat-resistant and oil-resistant synthetic rubber, and reference numeral 2 indicates a coil spring embedded in the reinforced elastic mat 1 with its axis parallel to the mat surfaces 8 and 4.

The coil spring 2 is preferably made of a corrosion-resistant material such as stainless steel, phosphor bronze, or carbon fiber, and the outer diameter of the coil spring 2 is made substantially equal to the thickness of the elastic mat 1 as shown in FIG. As shown, the outer peripheral surface of the coil spring 2 is exposed on the surface of the reinforced elastic mat 1. Further, the material cross section of the coil spring may be either round or square.

The mat surfaces 8, 4 are provided with outer circumferential protruding edges 5, 6, respectively, and the flat reinforced elastic pine 1 is sandwiched between rigid support plates 7 such as metal plates from both sides in a sandwich-like manner. 1 and the mounting holes 8 and 9 provided through the support plate 7.
0 and the connecting fitting 11 are inserted, and the connecting fitting 11
are joined together by. The length of the spacer 10 is preferably shorter than the thickness of the mat 1 to correspond to the allowable amount of elastic strain.

When the anti-vibration mat device having the above-described structure is installed, for example, between a press machine frame and a fixed base, the weight of the press is uniformly applied to the flat reinforced elastic mat 1 via the upper metal support plate 7. The outer peripheral protrusions 5, 6
The upper and lower metal support plates 7 and the flat reinforced elastic mat 1 support the weight of the press while being in substantially close contact with each other.

As a result, during press operation, the press load, shock, and vibration acting on the upper metal support plate 7 compress the flat reinforced elastic mat 1, thereby elastically deforming the coil spring embedded in the mat in the diametrical direction. , thereby providing load support, vibration absorption and shock damping within the elastic deformation, and preventing vibrations and shocks from being transmitted to the fixed base via the lower metal plate.

According to the present invention, a flat reinforced elastic mat in which a plurality of coil springs having an outer diameter equal to the mat thickness are buried with their axes parallel to the mat surface is sandwiched between rigid support plates from both sides. This makes it easy to insert between the machine, etc. to be supported in vibration isolation and its fixed base, and the load can be evenly transmitted from the machine, etc. to the fixed base, allowing each coil spring to absorb vibration and shock shock. The effect is that the action can be performed evenly, the overall vibration absorption and buffering action can be enhanced, and the life can be extended.
