Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a compressor support device, and particularly to a compressor support device suitable for preventing noise generation.

[Conventional technology]

A conventional compressor support device is disclosed in Japanese Utility Model Application No. 53-150510.
As described in the above publication, the outer peripheral portion was simply bent into an L-shape.

Below, the conventional compressor support device described above is shown in FIGS. 4 and 5.
This will be explained in detail with reference to FIG. FIG. 4 is a perspective view of the compressor. In FIG. 4, the support plate 2 is attached to the compressor main body 1 by welding. FIG. 5 is an enlarged sectional view taken along the line FF of the support plate 2 in FIG. FIG. 6 is an explanatory diagram showing the process of drawing the support plate 2 from the state of the raw material 4. In general, the support plate 2 requires strength, so a thick plate is used, and A raised portion 2a is provided on the outer periphery of the support plate 2 for reinforcement. 2b is a burr formed on the end piece of the rising portion 2a. In FIG. 6, the material 2' of the support plate 2 is pressed into the female mold 4 by the male mold 3 and molded.The material 2' pushed into the female mold 4 is shown by a dashed line. Thus, the shape of the support plate 2 is obtained.

The burr 2b is generated when the material 2' is pushed into the female mold 5 by the male die 4, and the outer peripheral portion of the material 3 is squeezed toward one end of the material 2'.

[Problem that the invention seeks to solve]

In the above-mentioned prior art, the outer surface of the material 2' is squeezed by the female die 5 because the rising part of the material 2' is short. As a result, the material on the upright portion moves, and sharp burrs 2a are generated on the outer peripheral portion of the support plate 2 after molding, as shown in FIG. Vibration from the compressor main body 1 is transmitted to the spring 2a via the support plate 2, and there is a possibility that noise may be generated from the spring 2a due to the vibration of the spring 2a.

The purpose of the present invention is to prevent the occurrence of paris,
An object of the present invention is to provide a support device for a compressor that prevents the generation of noise from Paris.

[Means for solving problems]

The above object is achieved by providing a recess on the outer surface near the end of the L-shaped bent portion.

[Effect]

The four parts provided at the L-shaped end part, when bending the L-shape,
It functions to absorb the movement of the meat that occurs when the outer side is squeezed.

Therefore, since the material of the support plate does not protrude from the end, there is no occurrence of burr from the end surface as in the conventional case, and noise generation due to burr can be prevented.

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1, 2, and 3. 1 is a perspective view of the compressor, FIG. 2 is an enlarged cross-sectional view taken along line A-A in FIG. 1, and FIG. 3 is an enlarged cross-sectional view of section B in FIG. 2.

In FIG. 1, reference numeral 2 denotes a support plate of the present invention, which is welded to the compressor main body 1.

This support plate 2 has a second
As shown in the figure, a recess 2c of the present invention is provided. This recess 2c is designed to be provided before drawing.

Therefore, as shown in FIG. 6, when the support plate 2 is drawn, the outer surface 2d is squeezed, but since the recess 2c is provided as shown in FIG.
It is absorbed in this recess 2c as shown by the dashed line. Therefore, unlike in the past, sharp cracks do not occur at the edges, so
There is no need for additional post-processing to remove burrs.

In addition, this type of support plate is manufactured using a progressive mold using coil material, so creating the recess before drawing requires only an additional step in the mold. Must not be.

Moreover, since the present invention does not generate any cracks on the support plate,
The vibrations of the compressor are transmitted from the support plate to the paris, and the vibrations of the paris do not generate noise from the paris.

〔Effect of the invention〕

According to the present invention, the concave portion provided on the outer periphery can prevent the generation of burrs due to the drawing process, so it is possible to prevent the generation of noise due to burrs, and also to eliminate the burr removal process, thereby reducing processing costs. I can do it. Note that the same effect can be obtained by providing an inclined surface instead of the recess.
