という欠点がある。Conventionally, a copying machine roll used in a PPO copying machine, etc. is made of a hollow pipe, and includes a roll body having a uniform diameter, a seal body provided at both ends of the seal body, and a rail body extending in the axial direction. and a bearing portion protruding concentrically. As shown in FIG. 6, such a roll for a copying machine usually has a simple pipe-shaped core (1), a bearing (2), an end face, and a part of the shaft of the roll body which are cold forged. Alternatively, members formed integrally by cutting or other means are joined together by welding means such as pressure welding, and the strength of the joint is weak (1\\ There is a drawback.In addition, the roll body / D The concentricity with the bearing part (toward) is not sufficient, and even if the surface is finished concentrically by cutting, the wall thickness is not even, and the rotation is not balanced, causing vibration during high-speed rotation. The disadvantage is that it is easy to cause

点がある。In addition, since the three members are fabricated individually and then joined together, the disadvantage of high production cost is eliminated, but in order to eliminate the disadvantage of increasing the value, Il17v! As shown in Fig. J, an integrated four for copying machines has been proposed, which is formed by swaging a single pipe with shoulders and bearings at both ends. However, because the shape of the shoulder of this machine is gently tapered, the length of the roll metal body is longer than the length of the four-wheel body, making it difficult to convert the entire copying machine into a comb. Furthermore, when applying rubber staining to this product, wasteful rubber material (section (4) in FIG. 7) is required, resulting in high material costs. Furthermore, even if the tapered shoulder formed by the swaging process is machined to form the end face where the bearing is locked and part of the corner, the remaining wall thickness will be too thin. The disadvantage is that it cannot maintain its strength.

結果、本発明を完成するにいたった。Therefore, the inventor has eliminated all the disadvantages in price, has good rotational balance, low manufacturing cost and material cost, and has a relatively short overall length compared to the length of the roll body. As a result of repeated efforts to provide an integrated roll for copying machines, we have completed the present invention.

とにより、加工しつる。As shown in Figures 1 and 1, the integral roll of the present invention includes a roll body (1) made of a pipe made of plastic material, and end surfaces (2) extending radially inward from both ends of the roll body (1).
A bearing part (8) extending in the axial direction from the end face (2), and a bearing part (8) extending from the end face (2) to the roll body (l)
) are integrally drawn. Since the one-piece roll of the present invention is integrally drawn, as shown in FIG. 1b, the roll body (1), end surface (1) The thickness of the bearing portion (Jl) and the bearing portion (Jl) are uniform. Also, since it is drawn and not swedaged,
An end face (8) extends radially inwardly and approximately at right angles to the roll cylinder [(1). Therefore, the overall length of the roll is relatively short, and even if rubber lining is applied, no wasteful rubber material is required, and sufficient strength can be maintained even if a part of the corner where the bearing fits is formed by cutting. Further, the integral roll of the present invention is manufactured using a highly ductile aluminum material, brass, or copper pipe to have a wall thickness of 0.5 to 7 mm. Furthermore, a structure in which the ratio of the outer diameter of the shaken bearing part to the outer diameter of the fist pipe is 5$6 to 1:6 can be suitably adopted. Explain 0 First, as shown in Fig. 3, a cylindrical pipe (4) as a raw material is placed in a first mold (5) having an inner diameter approximately equal to the outer diameter of the pipe (4), with a portion remaining. and insert it. In this case, the upper part (5a) of the first mold is made into a split mold, etc., and after the pipe is inserted into the lower part (5b), the split part is brought into close contact with the outer periphery of the pipe (4). ,
This is preferable because it eliminates the need to use a press or the like that has an unnecessarily long pressurizing stroke. Next, a guide portion (6) having an inner diameter approximately equal to the outer diameter of the pipe, a step portion (7) having an inner diameter smaller than the guide portion (6), and a guide portion (6) and a step portion (γ). Tapered shoulder connecting (
8) and the second mold (9) formed by the pipe (4).
) in the axial direction (direction (4) in Fig. 5) (Fig. 1115). In this case, for example, the first gold II
(5) is fixed to a press bolster (not shown), etc., the second mold (9) is fixed to a press ram (not shown), etc., and by pressing them together, Processed vines.
そのようにして、パイプ（４）の一端ｔ−第２の金製（

成することができ絞り工程を終了する。In that way, one end of the pipe (4) - the second gold (
9) can be formed into a shape corresponding to the shoulder part (8) and step part (7), and the drawing process is completed.

絞り工程と同様の再絞り工程を行なう。Next, as shown in FIG. 4, the pipe (4) that has undergone the drawing process is placed in a mold (b) similar to the first mold (5).
and a mold similar to the second mold (9), in which the step part (
)) and the shoulder 1 having a smaller inner diameter than
A re-drawing process similar to the drawing process is performed using a gold re-drawing mold consisting of (b) and (b) in which a tapered shoulder (g) larger than 16 (8) is bored.
この再絞り工程は、種々の加工条件により、適当回数行

外形まで細くシ、端面体）を軸心に対して直角にする。In this way, the outer diameter of the bearing part (5) is gradually made thinner, and the angle of the end face (2) approaches Gi, which is approximately perpendicular to the precision, and finally a re-drawing die as shown in No. 5vA is formed. A final piece of gold similar to that with the shoulder N- extending in the flat diameter direction of the guide part (using ■) is used, and the outer diameter of the bearing part (n) is thinned to the desired outer shape, and the end face body) is made. Make it perpendicular to the axis.
そのようにして最終絞り工程を終了する。In this way, the final drawing step is completed.
かくして見られたパイプ（４）の外周に旋削や研磨など

This method has the advantage that the process flow can be simplified without going through different types of processes such as cutting and pressure welding, and it is easy to take measures such as automation. As a result, production costs can be significantly reduced. In addition, since plastic working is carried out almost to the final shape, there is less cutting waste, which improves material yield and saves material costs.

A method of manufacturing an integral roll consisting of. 6 The drawing process, the re-drawing process and the final drawing process are
Claim 5 applied to both ends of the pipe simultaneously
The method described in section.
