Abstract

PURPOSE:To improve manufacturing efficiency without needlessly increasing the thickness of a shape material by disposing a canister, consisting of plural members having opposing surfaces which come into surface contact with the main surface of an aluminum shape material in the extruding direction, just behind an extruder. CONSTITUTION:The opposing surfaces of upper and lower blocks 2a, 2b of a canister 2 are constituted of a surface which comes into contact with the main surface 1b of an aluminum shape material 1 and a surface which has a recessed part or a grooved part 2c for preventing the surface from colliding with a projection 1a. The canister 2 is disposed just behind an extruder, and is straightened while being extruded, by passing it through the blocks of canister 2 in a state of being in surface contact with them.

However, when an aluminum section with a complicated shape is extruded, or when the bearing surface of an extrusion die wears out, the aluminum section becomes bent or bends more frequently. In order to completely prevent and reduce the frequency of such bending, the thickness of the aluminum profile is increased when designing an extrusion die, but this reduces the yield of aluminum profile manufacturing. So I don't like it.

B) Structure of the Invention The present invention provides an aluminum shape straightening device in which a canister consisting of a plurality of members having opposing surfaces that are in contact with the main surface of the aluminum shape and in surface contact in the extrusion direction is arranged immediately after extrusion. O) Embodiments Hereinafter, embodiments of the present invention will be explained with reference to the drawings ft.
2 is an aluminum profile, and 2 is a canister. As is well known in the art, aluminum profiles are provided with projections 1a of various shapes necessary for building parts, as well as grooves, recesses (not shown), and surface portions 2 exhibiting their structured contours. The portion excluding these protrusions 1a and the like is the main surface 1b of the aluminum profile 1. Although the canister 2 according to the present invention may be made of an appropriate number of members for construction purposes, it is shown in the drawing that it consists of two upper and lower 7" o.
Canisters 2 are shown from a and 2b, and the opposing surfaces of these upper and lower blocks 2a and 2b are in contact with the main surface 1b of the aluminum profile 1, and the protrusion 1
It has a recess or groove 2C for escape. Figure 2 shows a state in which the upper and lower parts 2a and 2b of the canister 2 according to the present invention are in contact with each other with the aluminum section 1 interposed therebetween. As can be seen in FIG. 2, the main surface (not shown) of the aluminum profile 1 is formed by the upper and lower blocks 2a, 2b, ! of the canister 2 in the extrusion direction E. =il is in contact. Furthermore, since the canister 2 is placed immediately after the extruder (not shown), the extrusion force causes the aluminum profile 1 being extruded to pass through the canister 2 in surface contact with the blocks of the canister 2. and correction is made during this pass.

FIG. 3 is a drawing showing an example of the arrangement position of the correction canister. In the figure, 10 is the extruder main body, 12 extrusion dies, 13 bolsters, 14 cutting devices, 15 aluminum forms, 16 pullers, 17 stems, 18 containers, 19 dummy blocks, and 22 billets. . The puller 16 is arranged rearward in the extrusion direction E than the canister 2, and the puller 16 is connected to the aluminum profile 15'.
As a result of gripping ft and indexing or pulling it out, the straightening force is applied to the aluminum profile 15 not only by the force of the stem 17 pushing against it, but also by the pulling force.

When the straightened aluminum profile 15 has been pulled out a predetermined distance, the cutting device 14 cuts the profile 15. Subsequently, the cut aluminum profile 15 falls from the puller 16 onto the conveying table 20, and the puller 16 moves forward in the extrusion direction E, and the straightened aluminum profile 15 is again gripped by the sealer 16. be done. The chucking point at which the puller 16 starts gripping the aluminum profile 15 is generally at the rear of the cutting device 14 in the extrusion direction E, but even if it is at the front, it is generally from the die side of the Zelsta 13 to the canister 2. The distance is 1 to 8 m.
