本発明は、中空軸（中空部が軸の長さ方向で遮
断されているものやロール類を含む）の加工方法
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for processing hollow shafts (including shafts in which the hollow portion is interrupted in the length direction of the shaft and rolls).
例えば、カレンダ、エンボスシング、プリンタ
等の分野では、合成樹脂、ゴム等を中空軸を用い
て圧延し、厚さ、模様、色付け等を均一にする作
業を行つている。 For example, in the fields of calendars, embossing, printers, etc., synthetic resins, rubber, etc. are rolled using hollow shafts to make the thickness, pattern, coloring, etc. uniform.
ところで、中空軸の使用温度が常温時と異なる
場合、熱膨張又は収縮の偏差、即歪により中空軸

範囲となるので、歩留りが低下する。更にこのよ
うな厚み精度の他、模様、色柄等の均一性精度も
損われてしまう。 By the way, if the operating temperature of the hollow shaft is different from normal temperature, the hollow shaft will bend in the axial direction during elastic deformation due to deviations in thermal expansion or contraction, and instant strain, and this bending will occur when the hollow shaft is rotated. It appears as "shake". If rolling work is performed with "runout" occurring,
As shown in FIG. 1, unevenness occurs on the surface of material (a), and the range shown by b is actually usable as a product, resulting in a decrease in yield. Furthermore, in addition to such thickness accuracy, uniformity accuracy of patterns, color patterns, etc. is also impaired.
そこで従来、前記の歪を防止する方法として、
中空軸の材質を全く均一に作るとか、使用温度状

準を超えたものを廃却していた。 Therefore, as a conventional method for preventing the above distortion,
Methods have been considered, such as making the material of the hollow shaft completely uniform or processing it at the operating temperature, but for example, the operating temperature is high (for PVC calendars, it is approximately
180 to 200℃), it has not been put to practical use due to problems such as how to heat the hollow shaft, temperature maintenance, uniformity (temperature unevenness), ease of handling, safety, and degree of heat influence on processing machines. Generally, they are used as they are after being processed at room temperature, or a certain accuracy standard is set and those that exceed that standard are discarded.

つた。 For this reason, conventionally, the distortion of the hollow shaft during use is removed in advance by giving the same strain to the hollow shaft at room temperature as under the conditions of use, and then grinding the surface of the hollow shaft under that condition, thereby improving the product thickness accuracy. This was a method for processing hollow shafts that was intended to save raw materials and improve yields.

ことによりロールを曲げている。 This type of machining method has conventionally been described, for example, in Japanese Patent Application Laid-Open No. 55-90714, in which bolts are inserted into the circumferential holes of a drilled roll, and both ends of the roll are The roll is bent by tightening the bolt with a nut at the surface and applying compressive force to the roll.

より長いボルトしか用いることはできなかつた。 However, in the above-mentioned processing method, an external force is applied parallel to the roll axis, and the bending moment arm is equal to the distance between the roll axis and the bolt axis. cannot be made larger than the roll radius, it is not easy to apply a bending moment to the roll, and only bolts longer than the roll length can be used.

加工には適用できなかつた。 Furthermore, since compressive force is applied to the roll by tightening nuts from both end faces of the roll, the bending curve can only be symmetrical at all times, and there is also the risk of damaging both end faces of the roll, causing water leakage, etc. Further, it cannot be applied to processing of bored rolls (rolls having a hole at one location in the center of the shaft diameter) other than drilled rolls.

である。 In view of these circumstances, the present invention makes it possible to easily apply a bending moment from inside the hollow shaft without damaging the end face of the hollow shaft of drilled rolls, bored rolls, etc., to create a desired bending curve, and to improve product thickness accuracy. The purpose of the present invention is to provide a method for processing a hollow shaft that can improve the manufacturing efficiency, save raw materials, and improve yield.

ことを特徴とするものである。 The present invention involves inserting into the hollow shaft a rod having a smaller diameter than the hole diameter of the hollow shaft, and a fulcrum ring fitted on the outer periphery of the rod so as to be slidable in the length direction of the rod. supports the rod in place,
Next, an external force is applied from the outer periphery of the rod in a direction perpendicular to the rod axis at a position a required distance away from the fulcrum ring of the rod toward the end of the hollow shaft, and the reaction force is applied to the end of the hollow shaft. By applying a bending force in the opposite direction between the rod and the end of the hollow shaft, the hollow shaft is deformed so as to generate a strain similar to that under use, and in the deformed state of the hollow shaft, It is characterized in that the surface of the hollow shaft is ground to remove distortion under usage conditions, and then the rod and fulcrum ring are removed.

除去した後、ロツド及び支点環が取除かれる。 Therefore, when machining a hollow shaft, if a fulcrum is created inside the hole of the hollow shaft using a fulcrum ring and an external force is applied to the rod inserted into the hollow shaft in a direction perpendicular to the rod axis, the reaction will be A force acts on the end of the hollow shaft, causing the hollow shaft to bend in the opposite direction to the bending of the rod.
A strain similar to that under the use condition is generated in the hollow shaft, and in this state, the surface of the hollow shaft is ground to remove the strain under the use condition, and then the rod and the fulcrum ring are removed.

After the measurement is completed, as shown in Fig. 2C, the hollow shaft 1 is returned to room temperature and the bending mechanism 2 is assembled, and then the bending mechanism 2 is used to adjust the usage condition to the hollow shaft 1 as shown in Fig. 2. It is bent in the same manner as below, and in that state it is ground to a state without distortion as shown in Fig. 2E.

台である。 The details of the bending mechanism 2 will be explained with reference to FIGS. 3A and 4. The bending mechanism 2 includes a hollow shaft 1
Rod 3 with a smaller diameter than the hole diameter of the hollow shaft 1 to be inserted inside
, a pair of fulcrum rings 4 that are fitted between the rod 3 and the inner wall of the hollow shaft 1 and support the rod 3;
A pair of support tubes 5 are fitted at both ends of the rod 3, and the rods 3 are screwed into the respective support tubes 5, and the rods 3 are spaced from each fulcrum ring 4 of the rod 3 toward the end of the hollow shaft by a required distance in the length direction. Each push bolt 6 is used to press the end of the rod 3 by applying an external force from the outer periphery of the rod 3 in a direction perpendicular to the axial center line of the rod 3 at a position where the rod 3 is bent. In the figure, 7 is a processing pedestal.

確に作り出すことができる。 When the bending mechanism 2 is assembled to the hollow shaft 1, when the push bolts 6, 6 are tightened, forces F 1 and F 2 are applied to the rod 3, respectively, and F 1 ×l is applied with the fulcrum rings 4, 4 as the origin. 1 , a bending moment of F 2 × l 2 occurs. As a result, a displacement of deflection δ B is observed at a position an arbitrary distance x away from the origin. On the other hand, by tightening the push bolts 6, 6, the hollow shaft 1 has R 1 and
Force R 2 is applied, F 1 ×l 1 = with fulcrum ring 4 as the origin
A bending moment of R 1 ×l 3 , F 2 ×l 2 =R 2 ×l 4 is generated. By using this bending moment, it is possible to artificially and accurately create a displacement of deflection δ S at a position an arbitrary distance x away from the origin.

れば、逆に歪量＝δSとして、R1，F1，R2，F2，
l1，l2，l3，l4の数値を決めることができる。 Further, the bending curves of the hollow shaft 1 and the rod 3 can be easily determined by a certain calculation method if the respective shapes are known. In other words, if we measure the amount of strain under the usage conditions, we will get R 1 , F 1 , R 2 , F 2 ,
The numerical values of l 1 , l 2 , l 3 , and l 4 can be determined.
従つてこの方法により、常温時にあらかじめ歪

状況下での歪を除去することができる。 Therefore, by this method, after bending the hollow shaft 1 corresponding to the amount of strain δ S in advance at room temperature,
By grinding the surface of the hollow shaft 1, distortion under usage conditions can be removed.

等、自由な曲線が簡単且つ正確に設定できる。 Of course, even if the distortion of the hollow shaft 1 is not symmetrical, there are ways to change the balance between F 1 and F 2 , ways to change l 1 and l 2 depending on the set position of the fulcrum ring 4, and l 3 and l 4 in Fig. 3B. Various curves can be drawn, such as by changing the number of fulcrum rings 4, by increasing the number of rods 3, and by appropriately combining the above ~.
By changing the direction of the push bolts 6, 6 on the left and right sides or increasing the number of push bolts 6, 6, the hollow shaft 1 has a two-dimensional strain (X-Y (in-plane) or three-dimensional distortion with respect to the axis as shown in Figure 6 (X-Y-Z plane)
etc., free curves can be set easily and accurately.

Experimental results for mm drilled rolls are shown.
In other words, the operating temperature of this drilled roll is 180℃, and the maximum strain at that time is approximately at the center of the roll body.
It was 10μ. In order to remove this distortion, we calculated F 1 , F 2 , l 1 to l 4 using the method described above, and found that F 1 = F 2 =
It was found that it would be sufficient to set the weight to about 2.600Kg, l 1 = l 2 = 500 mm, and l 3 = l 4 = 360 mm. Therefore, the diameter of rod 3 is
Insert a 120mm roll, grind under the above conditions at room temperature with the roll bent, and then grind again.
When heated to 180°C and measured the amount of strain, the maximum value was 2μ.

On the other hand, the one shown in FIG. , the rods 3 inserted into the hollows at both ends of the hollow shaft 1' are attached to the fulcrum rings 4, 4'.
The 3 ends of each rod are tightened by push bolts 6 screwed onto the ends of the hollow ring 1'.
