Abstract

The present invention relates to an integrated extrusion device capable of both direct extrusion and indirect extrusion. When direct extrusion is performed, direct extrusion is performed by coupling the stem and extrusion mold to the moving part and moving guide. In addition, when performing indirect extrusion, indirect extrusion can be performed by combining the blocking part and stem mold with the moving part and moving guide, so both direct and indirect extrusion are possible using one device, depending on the site situation. There is an effect in that direct extrusion or indirect extrusion can be selectively performed.

Description

Integrated extrusion apparatus capable of direct and indirect extrusion {Integrated Extrusion Apparatus with Direct and Indirect Extrusion}

The present invention relates to an integrated extrusion device capable of direct extrusion and indirect extrusion. More specifically, direct extrusion enables both direct extrusion and indirect extrusion, and allows direct extrusion or indirect extrusion to be selectively performed depending on the site situation. and an integrated extrusion device capable of indirect extrusion.

In general, an extrusion device is a device that forcibly extrudes the raw material introduced into the device after preheating it toward the outlet of the tip having a desired cross-sectional shape, passing through the mold with the extrusion force to obtain an extrudate with a desired cross-sectional shape. It has the advantages of high production speed, relatively simple post-processing, and low cost. This extrusion device is mainly performed under temperature conditions where the material has low deformation resistance, that is, hot, and is mainly used for the production of rods or profiles, but is also used for the production of long products with irregular cross sections for soft materials. , it is possible to manufacture cross-sections of complex shapes depending on the type of alloy and mold shape.

Figure 1 (a) is a diagram schematically showing a conventional direct extrusion device. Referring to Figure 1 (a), the conventional direct extrusion device is located on one side of the container 10, the container 10, into which the billet (B), which is an extrusion raw material, is charged, and the billet (B) is placed in the container ( 10) It includes a stem 20 that is pushed inside and extruded, and a die 30 that is coupled to the other side of the container 10 and determines the extrusion shape of the billet (B). Die 30 is supported on die support 32. And after the billet (B) is charged into the container (10), the ram (22) connected to the stem (20) applies pressure to the stem (20), or a separate hydraulic means (not shown) applies pressure to the ram (22). When pressure is applied, the stem 20 moves forward and applies pressure to the billet B, so that the billet B passes through the die 30 and the molded product is extruded.

In this direct extrusion device, the moving direction of the ram 22 and the moving direction of the billet (B) are the same, and the billet (B) is effectively extruded due to frictional heat caused by friction on the outer circumference. However, after extrusion is completed, about 25% of the billet (B) remains as chips, making it uneconomical.

Figure 1(b) is a diagram schematically showing a conventional indirect extrusion device. Referring to (b) of FIG. 1, the conventional indirect extrusion device includes a container 50 into which the billet (B), which is an extrusion raw material, is charged, and an empty space is formed along the center longitudinal direction, located on one side of the container 50. a ram 60, a die 70 formed at the end of the ram 60 to determine the extrusion shape of the billet B, and a fixing plate that closes the other side of the container 50 and secures the container 50. Includes (80). And after the billet (B) is charged into the container (50), when the ram (60) applies pressure to the billet (B), the billet (B) passes through the die (70) and the molded product is extruded.

This indirect extrusion device is a case where the moving direction of the ram 60 and the moving direction of the billet (B) are opposite, and has the advantage of less material loss and lower power requirements compared to the direct extrusion device, but it is inconvenient to operate and has poor surface quality. There is a downside to not being good.

Accordingly, sites are often equipped with both direct and indirect extrusion devices, and overall consider the pros and cons of direct extrusion and the pros and cons of indirect extrusion, and choose whether to proceed with direct extrusion or indirect extrusion. However, providing both a direct extrusion device and an indirect extrusion device has the problem of being expensive and making the narrow indoor space even more cramped.

Next, referring to FIG. 12, when the hydraulic member 210 applies hydraulic pressure to the housing 200 and the ram 300 moves forward, the ram 300 moves forward and the moving part 310 connected to the ram 300 ) and the blocking unit 720 detachably coupled to the moving unit 310 moves forward along the ram 300. Then, the blocking unit 720 presses the container 400 forward, so that the mold protrusion 824 of the stem mold 820 is inserted into the container 400 through the front of the container 400. That is, the mold protrusion 824 is inserted into the container 400 by the forward pressure applied by the ram 300 to the container 400, thereby applying pressure so that the billet B charged into the container 400 is indirectly extruded. . Then, the billet (B) passes through the stem mold 820 and the molded product is extruded.

Next, referring to FIG. 13, when the extrusion of the molded product is completed, the moving cylinder 320 moves the moving part 310 backward, so that the blocking part 720 and the ram 300 move the moving part 310. Move it backwards accordingly. Afterwards, the cutting portion 650 of the cutting member 600 located on the upper side between the container 400 and the blocking portion 720 moves downward, and the remaining billet (B) located at the rear of the container 400 is moved downward. Cut the butt.

In this way, the present invention is to detachably couple the blocking part 720 to the moving part 310, and detachably couple the stem mold 820 to the front support part 120, and then charge the container 400. The billet (B) is indirectly extruded. In addition, in the present invention, when direct extrusion is performed, the stem 710 and the extrusion mold 810 are coupled to the moving part 310 and the moving guide 510 to perform direct extrusion, and when indirect extrusion is performed, the blocking part ( Since indirect extrusion can be performed by combining the 720) and the stem mold 820 with the moving part 310 and the moving guide 510, both direct and indirect extrusion are possible using one device, and field conditions There is an effect of being able to selectively proceed with direct extrusion or indirect extrusion.

Although the present invention has been described in detail in the above embodiments, it is obvious that the present invention is not limited thereto, and it is clear to those skilled in the art that various changes and modifications are possible within the technical scope of the present invention, and such changes and modifications are attached. If it falls within the scope of the claims, the technical idea should also be considered as belonging to the present invention.
