のである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for twisting a square pipe or flat steel into a torsion pipe or torsion flat steel, and to a machine for producing the torsion square pipe or torsion flat steel.

と、これは角鋼をねじって作った物ではなく、角鋼をね

ものである。従って重くて、価格が高い。2. Description of the Related Art As shown in FIG. 1 and FIG. 2, a steel bar having a twisted square or flat steel is attached to a vertical bar of a handrail for decoration. Therefore, first of all, regarding twisted square steel, it is not made by twisting square steel, but by melting iron or aluminum into a mold with twisted square steel. Therefore, it is heavy and expensive.

【発明が解決しようとする課題】そこで角鋼の一端を固

ると、弱い箇所からねじ切れてしまう。そこで角パイプ
が均一に、ねじ切れる事なく出来ると、従来の鋳物より
も軽くて、安い物が大量に出来る。Therefore, if one end of the square steel is fixed and the other end is turned and twisted, a weak spot is inevitably formed, so stress is concentrated there, and only the twist is twisted, and it is never uniform. I can't twist. Even more, if the square pipe is twisted, it will be cut from weak spots. Therefore, if the square pipe can be made evenly and without threading, it will be lighter and cheaper than conventional castings.

パイプを、予め挿入しておく。そして角パイプの一端を

麗にねじれる。In this solution, as shown in FIG. 5, a slightly smaller round pipe is inserted in advance into a square pipe. Then, fix one end of the square pipe and twist the other end to twist it uniformly and neatly everywhere.
【0005】[0005]
【作用】これはねじる過程で、角パイプの内径が小さく

になり、綺麗にねじる事が出来るのである。なお角パイ
プがねじられた後は、少し逆に回してねじりを戻すと、
中の丸パイプを抜く事が出来る。In the process of twisting, the inner diameter of the square pipe becomes smaller, and when it hits the inner round pipe, it will no longer be twisted there. Therefore, by twisting the inner surface of the square pipe until it entirely hits the round pipe, the pitch of the twist becomes uniform everywhere and it is possible to twist neatly. In addition, after the square pipe is twisted, turn it slightly backward to untwist,
The inner round pipe can be pulled out.
【0006】次にねじり平鋼について述べると、平鋼の
一端を固定し、他の一端を回してねじると、平鋼がどう

従ってピッチが均一で真直ぐなねじり平鋼が出来るので
ある。 Next, regarding the twisted flat steel, if one end of the flat steel is fixed and the other end is twisted, the flat steel will bend and cannot be twisted uniformly. Therefore, it is the fact that it is baked and corrected. Therefore, as shown in Fig. 6, when the flat steel is put into a round pipe where the flat steel just enters, and the flat steel is twisted, the twist pitch becomes uniform everywhere as well as the square pipe and twists neatly. You can do things. The reason is that when you start twisting the flat bar, the flat bar
Protrudes from the place and begins to deform. Then the inner wall of the round pipe
Hits, and the part stops deforming. Then
Deformation of a portion having a gap proceeds. In this way, the round pipe
The torsion is completed when the deformation spreads over the entire length.
Therefore, a straight torsion flat bar with a uniform pitch can be produced.
is there.

An embodiment of a machine for producing a twisted flat steel will be described with reference to FIGS. First, torsion angle pipes are manufactured.
To describe the manufacturing machine of (1), a torsion (2) is provided at the end of the machine base (1). The torsion portion has a torsion shaft (3) attached to the bearing, and the tip of the torsion shaft is square so that the inside of the square pipe can enter. The torsion shaft is slowly rotated forward or backward by the reduction motor A (4).

A square pipe passes through the guide roller with a slight gap. Endless chains (8) are mounted on both sides of the moving unit, and the moving unit is pulled by driving the chain. The chain is driven by a chain driving unit (9) provided at the other end of the machine base, and the chain driving shaft (11) is rotated by a deceleration motor B (10) to drive the chain.

First, the moving part (5) is brought closer to the torsion shaft ( 3). The square pipe (12) is passed through the guide roller (7) of the moving unit, and the tip is inserted into the square shaft at the tip of the torsion shaft (3).
Then, the aforementioned round pipe (13) is inserted into the square pipe. Then, the torsion shaft is slowly turned in the direction of the arrow to start twisting the square pipe, and then the moving part is gradually moved in the direction of the arrow to complete the torsion square pipe.
At the end of the twist, slightly twist the square pipe back and remove the round pipe inside.
