Description

[0001] ENERGY SAVING CONTAINER FOR EXTRUDING [0002]

The present invention relates to an extrusion container, and more particularly, to an extrusion container capable of saving energy.

Extrusion is a processing method in which a billet as an extruded material is placed in an extruded container and is pressed by a ram to be taken out through a die and is generally used for manufacturing a rod or a tube having a uniform cross section.

Typically, the extrusion container has a liner in direct contact with the billet and a mantle surrounding the liner from the outside. In the extrusion process, the extruded container serves to keep the preheated billet at a temperature suitable for molding. To this end, the extrusion container is provided with heating means for heating the mantle. Conventionally, as a heating means for heating the mantle, a plurality of heat cartridges inserted into the mantle are mainly used. However, since the heat cartridge is low in energy efficiency and has a low temperature rising speed, it is difficult to quickly respond to the extrusion of a high melting point material such as Ti material, and improvement is required.

FIGS. 3A and 3B show a first example in which a heating zone is set in the extrusion container shown in FIG. 1. FIG.
Figs. 4A, 4B and 4C show a second example in which the heating zone is set in the extrusion kettle shown in Fig.

Hereinafter, the configuration and operation of an embodiment of the present invention will be described in detail with reference to the drawings.

1 and 2 show an extrusion container according to an embodiment of the present invention as a perspective view and a longitudinal sectional view. A reference axis A extending in a straight line is introduced for convenience of explanation. Referring to FIGS. 1 and 2, the extrusion container 100 includes a liner 110, a mantle 120, a plurality of halogen lamps 130, and a filler 140.

The liner 110 is generally cylindrical in shape and is provided with a billet accommodating space 111 extending along the reference axis A therein. A billet as an extrusion material is accommodated in a billet accommodating space 111 and a billet accommodated in the billet accommodating space 111 is pressed by a ram to pass through a die (not shown) coupled to the extrusion container 100 . Since the material of the liner 110 is generally used, a detailed description thereof will be omitted.

The mantle 120 is generally cylindrical in shape and surrounds the liner 110 in the circumferential direction from the outside. The inner circumferential surface of the mantle 120 directly contacts the outer circumferential surface of the liner 110. [ A plurality of lamp insertion holes 121 are formed in the mantle 120 to receive the halogen lamps 130 therein. The plurality of lamp insertion holes 121 are formed by extending from the first end 122 of the mantle 120 in parallel with the reference axis A and forming a plurality of first lamp insertion holes And a plurality of second lamp insertion holes 121b which are formed extending from the second end 123 of the mantle 120 in parallel with the reference axis A and are arranged at regular intervals along the circumferential direction . The end of the first lamp insertion hole 121a and the end of the second lamp insertion hole 121b are spaced apart from each other by a predetermined distance. In the present embodiment, the first lamp insertion hole 121a and the second lamp insertion hole 121b are described as having 16, respectively. However, the present invention is not limited thereto and may be appropriately changed according to the size of the mantle 120 have. Since the material of the mantle 120 is generally used, a detailed description thereof will be omitted. In the present embodiment, a plurality of lamp insertion holes 121 are arranged at regular intervals along the circumferential direction, but the present invention is not limited thereto. That is, the plurality of lamp insertion holes 121 may be disposed at an appropriate interval instead of an equal interval, which is also within the scope of the present invention.

The halogen lamps 130 are inserted into lamp insertion holes 121 formed in the mantle 120, one by one, and extend in a straight line. Each of the plurality of halogen lamps 130 is disposed in parallel with the reference axis A in a state of being spaced apart from the liner 110 by a certain distance in the radial direction. The heat generated by the halogen lamp 130 heats the mantle 120 and the heat of the heated mantle 120 is applied to the liner 110 To the billet. Some of the plurality of halogen lamps 130 (sixteen in this embodiment) are inserted into the first lamp insertion holes 121a at equal intervals along the circumferential direction on the first end 122 side of the mantle 120 (Sixteen in the present embodiment) are inserted into the second lamp insertion holes 121b and arranged at regular intervals along the circumferential direction on the second end 123 side of the mantle 120. [ The sixteen halogen lamps located on the first end 122 side of the mantle 120 among the plurality of halogen lamps 130 are referred to as the front lamps 131 and the second end 123 of the mantle 120 The other 18 halogen lamps located on the side of the rear lamp 132 are referred to as a rear lamp 132. [ Since the halogen lamp 130 has lower power consumption than a cartridge heater used as a heat source in a conventional extrusion container, the energy saving effect becomes remarkable. Further, when the halogen lamp 130 is used, a high heating rate can be obtained, so that it is possible to cope with changes in extrusion conditions quickly and precisely, thereby improving productivity. Since the halogen lamp 130 can be heated at a high temperature of 800 to 1000 DEG C, the responsiveness to Ti and the high melting point extruded material is improved. In the present embodiment, the halogen lamps 130 are arranged at equal intervals along the circumferential direction. However, the halogen lamps 130 may be arranged at appropriate intervals instead of equally spaced according to the arrangement of the lamp insertion holes 121, . ≪ / RTI >

The filler 140 is filled in the space between the halogen lamp 130 and the lamp insertion hole 121 to prevent the halogen lamp 130 from being damaged by an external impact, Thereby preventing direct conduction to the inner peripheral surface. In the present embodiment, it is described that the heat-resistant cotton is used as the filler 140. [

Although not shown, the extrusion container 100 further includes a control unit for controlling the operation of the plurality of halogen lamps 130. [ A control unit (not shown) controls the plurality of halogen lamps 130 by dividing them into groups. That is, the mantle 120 can be divided into two or more along the circumferential direction or up to two heating zones along the longitudinal direction (reference axial direction). The halogen lamps 130 located in the respective heating zones form a group, and the outputs of the halogen lamps 130 in the same group are controlled together by a control unit (not shown). 3A to 4C show various examples in which a heating zone is formed. 3A to 4C , the one-dot chain line is a virtual dividing line for dividing the heating zone.

Referring to FIGS. 3A and 3B, two heating zones 150a and 150b are formed in the extrusion container along the circumferential direction. The heating zone along the longitudinal direction is not divided. Although not shown is, also be further divided into two along the longitudinal direction will be a total of four heating zones formed.

4A, 4B and 4C, the extrusion container is divided into four regions along the circumferential direction and at the same time, divided into two regions in the longitudinal direction so that a total of eight heating zones 160a, 160b, 160c, 160d, 161a, 161b, 161c, and 161d are formed. Although the present embodiment has been described by way of example in which two or four are divided along the circumferential direction, it may be divided into three or five or more. The four heating zones 160a, 160b, 160c and 160d located at the front and the four heating zones 161a, 161b, 161c and 161d located at the rear are located in the same phase, And can be positioned to have different phases. In addition, the number of the heating zones located at the front and the number of heating zones located at the rear may be different from each other, which also belong to the present invention.

Since the zone temperature control can be performed independently as described above, the extrusion quality and the productivity can be improved by eliminating the temperature deviation in the radial direction or the longitudinal direction or inducing an appropriate temperature deviation. In addition, the thermal fatigue of the mantle can be minimized and the life of the extruded container can be increased.

Although the present invention has been described with reference to the above embodiments, the present invention is not limited thereto. It will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims.
