Description

[Technical field]

[0001] The present invention relates to an apparatus for processing extruded materials such as aluminum. [Background technology]

[0002] Various types of apparatuses for processing this type of extruded material have been proposed in the past.

[0003] For example, Patent Document 1 discloses a manufacturing apparatus capable of manufacturing an aluminum extrusion material having a corrugated uneven pattern on the outer periphery.

[0004] In this manufacturing device, a shaping roll is provided along the extrusion path of the extrusion material extruded from the extruder. The shaping roll has a corrugated blade on its outer periphery, and during extrusion, the outer periphery blade of the roll bites into the outer periphery of the extrusion material and the roll rotates about the roll axis.

[0005] [Patent Document 1] Japanese Patent Application Publication No. 11-221613 Summary of the Invention [Problem to be solved by the invention]

[0006] However, with this manufacturing device, the outer blade portion of the shaping roll bites into the outer periphery (surface) of the extruded material, and there is no pressure on the inner periphery (back surface) of the extruded material, so not only is it impossible to accurately form the uneven pattern, but the inner periphery (back surface) cannot be made smooth.

[0007] The present invention has been made based on the above circumstances, and its object is to provide an extrusion material processing device that can accurately shape the surface and also form a smooth back surface. [Means for solving the problem]

[0008] In order to solve the above problems, the extruded material processing device of the present invention comprises a smooth roll that receives the back surface of the extruded material extruded from the extruder, a shaping roll that presses against the surface of the extruded material received by the smooth roll to give it a shape, and an adjustment means that supports at least one of the smooth roll and the shaping roll so that it can be displaced toward the other, and adjusts the pressing force of the shaping roll on the extruded material, and is characterized in that the smooth roll and the shaping roll are positioned away from the extruder and immediately after the extrusion of the extruded material. Effect of the Invention

[0009] According to the extrusion material processing device of the present invention, the front surface can be accurately shaped, and the back surface can be formed smoothly. [Brief description of the drawings]

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0012] In FIG. 1, reference numeral 1 denotes an apparatus for processing an extruded material M according to the present invention, and this processing apparatus 1 is provided adjacent to the rear stage of an extruder 2 .

[0013] The extrusion material M is made of, for example, aluminum or an aluminum alloy.

[0014] The extruder 2 has a die 3 and is configured to form an extruded material M by, for example, heating aluminum or an aluminum alloy and extruding it through the die 3.

[0015] The die 3 has an extrusion port 4 which is formed, for example, in a U-shape, so that the extrusion material M is formed into a U-shaped cross section in the width direction having a flat plate-shaped portion 5 and a pair of side plate portions 6 rising from both sides of the flat plate-shaped portion 4.

[0016] As also shown in Figures 2 and 3, this processing device 1 is equipped with a smooth roll 7 that receives the back surface of the extruded material M extruded from the extruder 2, and a shaping roll 8 that presses against the surface of the extruded material M received by this smooth roll 7 to give it a shape.

[0017] The smooth roll 7 and the shaping roll 8 are provided at a distance from the extruder 2 and immediately after the extrusion of the extruded material M, and are adapted to contact the extruded material M and follow the extruded material M so as to sandwich the extruded material M.

[0018] The smooth roll 7 is formed so that its width is narrower than the width of the flat portion 5 of the extruded material M, and is configured to receive the rear surface of the flat portion 5 of the extruded material M from between the side plate portions 6.

[0019] The shaping roll 8 has shaping recesses 9 formed on its peripheral surface, and is adapted to be pressed against the surface of the flat plate portion 5 of the extruded material M to form a pattern consisting of numerous protrusions 10 .

[0020] Furthermore, the processing apparatus 1 is provided with a support frame 11 that supports the smooth roll 7 and the shaping roll 8 .

[0021] That is, as shown in Figures 4 and 5, the support frame 11 is provided with a pair of fixed support parts 12 and a pair of movable support parts 13, and the smoothing roll 7 is supported for free rotation on the fixed support parts 12 via fixed bearings 14, and the shaping roll 8 is supported for free rotation on the movable support parts 13 via movable bearings 15.

[0022] In addition, the movable support portion 13 supports the shaping roll 8 so that the shaping roll 8 can be displaced toward the smoothing roll 7 .

[0023] Furthermore, the support frame 11 is provided with an adjustment screw (adjustment means) 16 for displacing the movable support portion 13, so that the pressure of the shaping roll 8 against the extrusion material M can be adjusted.

[0024] According to the above configuration, as shown in FIGS. 6 and 7, the extrusion material M extruded and molded from the die 3 of the extruder 2 is shaped by the shaping roll 8 provided immediately after the rear stage of the extruder 2.

[0025] At this time, the extruded material M, which is still in a high temperature state, has its back surface received by the smooth roll 7 and its front surface pressed against the shaping roll 8 to be shaped.

[0026] Therefore, the pattern of the convex portions 10 corresponding to the concave portions 9 for shaping is formed accurately and with good quality on the surface of the extruded material M, and the back surface is formed smoothly.

[0027] Furthermore, by shaping the surface of the extruded material M, it is possible to make it less susceptible to wrinkles during post-processing.

[0028] In the above embodiment, the shaping recesses 9 are provided on the surface of the shaping roll 8. However, in the present invention, the shaping protrusions may be provided on the surface of the shaping roll 8 to form recesses in the extruded material M.

[0029] Moreover, although the shaping roll 8 is provided so as to be displaceable, the smooth roll 7 may be provided so as to be displaceable, or both the smooth roll 7 and the shaping roll 8 may be provided so as to be displaceable.

[0030] Furthermore, the smoothing roll 7 and the shaping roll 8 are configured to be in contact with the extrusion material M and to follow the movement of the extrusion material M, but may be configured to be driven by a motor or the like.

[0031] Furthermore, the extruded material M is formed so that its cross section in the width direction is U-shaped, but it may be formed so as to have a flat plate shape without side plate portions 6, for example, as shown in FIG.

[0032] The disclosure regarding the present invention described above can be summarized at least as follows.

[0033] In other words, the extruded material processing device of the present invention comprises a smooth roll that receives the back surface of the extruded material extruded from the extruder, a shaping roll that presses against the surface of the extruded material received by the smooth roll to give it a shape, and an adjustment means that supports at least one of the smooth roll and the shaping roll so that it can be displaced toward the other, and adjusts the pressing force of the shaping roll against the extruded material, and is characterized in that the smooth roll and the shaping roll are positioned away from the extruder and immediately after the extrusion of the extruded material.

[0034] The present invention can include at least the following embodiments, which can be adopted separately or in combination with each other.

[0035] (1) The smooth roll and the shaping roll are configured to be in contact with the extrusion material and to follow the movement of the extrusion material.

[0036] (2) The extrusion material is made of aluminum or an aluminum alloy.

[0037] (3) The shaping roll has a shaping recess on its peripheral surface. [Explanation of symbols]
