Abstract

PURPOSE:To compress a highly bulky object and to reduce volume by disposing dies having guiding parts extending in parallel from both projecting ends in curved parts by facing each other and attaching and detaching these. CONSTITUTION:Molding dies 1, 11 are opened to the right and left, and a highly bulky object is charged into the space for accepting the work between these. The die 11 is forced in the direction of an arrow by a cylinder 13 connected to the die 11. The object having higher bulkiness is forced to the inner sides of the dies 1, 11 by the gradients of fork parts 21, 23. Further, when the die 11 is forced in, the object having higher bulkiness is deformed approximately to the intended shape by the guide of the parts 21, 23 and the curved parts 3, 7 of the dies 1, 11. The die 11 is forced in further until the parts 21, 23 fit to each other and the dies 1, 11 form the intended shape perfectly, whereby the object having higher bulkiness is compression molded.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for compressing bulky objects to reduce their volume.

Generally, when inserting a bulky item into a small space (space), it is necessary to disassemble it to fit the dimensions of the small space.
Although methods such as molding using a compression device are adopted, disassembly work for this requires a large amount of labor, or a special separate device is required, which wastes time, money, and installation space.

For example, when compressing and reducing the volume of frame filters used in nuclear power plants, etc., a mold as shown in Figure 1 is used to shape the large frame filter 03 into a shape that can be stored in a drum can or the like with a smaller diameter than the filter. Shape. In this case as well, a method is adopted in which the width of the frame filter 03 is narrowed by using preforming molds 02a and 02b so as to fit inside the molds 01a and Olb for forming the filter into a circular shape. (If this is not done, the dimensions of the molds 01a and Olb will become considerably large, and special molds will be required for each large and small filter 03.)However, space is required for the preforming molds 02a and 02b and their driving device. Therefore, the installation space for this compression device becomes large. Also, preforming mold 02a or 02
When b is not used, mold 01a.

A part of the frame of the frame filter 03 gets caught in the meeting portion of the oib, making it impossible to obtain a satisfactory compressed shape.

The present invention has been made in view of the above-mentioned circumstances, and is capable of compressing a frame filter consisting of a frame assembled in a rectangular shape and a transparent member stretched in the frame by preventing the frame from being caught. The purpose of the present invention is to provide a compact compression and volume reduction device that can be used in various ways.

The present invention will be explained below based on the illustrated embodiments. Second
2 is a perspective view showing the entire embodiment of the present invention, and FIG. 4 is a perspective view showing the entire embodiment of the present invention.
2 is a plan view showing the main parts of the same embodiment, but in FIG. It consists of guide parts 5 that protrude in parallel from the protruding ends of both ends of the guide part 3.

The guide part 5 has a Y plate shape, and inside thereof.

A sliding guide groove, which will be described later, is cut.

The mold 1 has a main body 8 in which a curved part 7 having a similar shape opposite to the curved part 3 is formed inside the tip of the guide part 5 of the mold 1.
1 is fitted, and a reciprocating drive device, ie, a hydraulic cylinder 13, is connected to the back of the main body 8.

The hydraulic pump, control valve, tank, hydraulic piping, etc. connected to the hydraulic cylinder 13 are not shown because they are well known to those skilled in the art.

FIG. 3 is an enlarged perspective view showing details of the guide section 5. FIG.

In FIG. 3, a guide groove 15 cut parallel to the inner surface of the guide portion 5 is aligned and connected to a guide hole 16 formed through the main body 4. As shown in FIG. As shown in FIG. 2, the guide portions of the mold 11, that is, the guide rods 18, are slidably fitted into the guide grooves 15 that have been cut in five grooves, and the tips thereof are connected to the guide holes 16.
They protrude from the outer end of the mold 1 through the support member 1, and are further connected to each other by a beam member 19.

Furthermore, in the mold 1, a fork portion 21 which is inclined in the horizontal plane is formed between the bay part 3 and the guide part 5, and also in the mold 11.

A similar fork portion 23 is formed between the bay portion 7 and the guide rod 18.

In this embodiment with the configuration described above, #'! '; The process of compressing a frame filter ioo having a square frame 101 will be described with reference to FIGS.

(a) Open the molding molds 1 and 11 to the left and right, and insert the frame filter 100 into the compressed object receiving space between them.

(b) The molding die 11 is pushed in the direction of the arrow by the hydraulic cylinder 13 connected to the molding die 11. This results in
The slope of the fork portions 21,23 forces the frame filter 100 into the inside of the mold 1°11.

(c) When the molding die 11 is further pushed in, the 7-occupancy part 21
．． 23 and the curved part 3.7 of the molding die 1.11, the frame filter 100 is deformed.

Approach the desired shape. At this time, since the frame 101 of the frame filter 100 is pushed in by the fork portions 21 and 23, it is not sandwiched between the left and right molds 111.

(d) Push the molding die 11 further, and press the fork part 21.
．． 23 fit into each other, the mold 1.degree. 11 completely forms the desired shape, and the large frame filter 100 is compression molded into a small volume.

As described above, the fork portions 21 and 23 located on the outside of the bayous portions 3 and 7 of the molds 1 and 11 facing each other push the framework 1° 1 of the framed filter 100 inward, so that the mold 1
.

In the above embodiment, an example in which the square frame filter 100 is compressed has been described, but the fork portion 2
Of course, if the horizontal inclination angle of 1.23 is adjusted, the scales can be compressed and reduced in volume of other shaped objects.
