Description of the Invention (1) [Technical Field] ~ The present invention relates to an annular roll exchange method and device for an easy-to-operate strip steel rolling mill. And the ring roll exchange device is formed by the main body of the steel roll mill with the roll replacement mechanism and the roller suspension device. [Technical Background] The last section of the continuous rolling mill line of hot-rolled wire rods, bars, and other strips is equipped with most sizing machines. The sizing machine uses a strip rolling mill in which most of the roll fittings are arranged at equal angular intervals around the center of the rolling path and are supported by the shell. The so-called roll fitting is a composite of the ring contacting the material being rolled and the roller shaft fitted in the ring hole of the ring roller to support the ring roller. In Japanese Unexamined Patent Publication No. 1 1 — 1 0 4 7 0 6 A strip steel rolling mill with a structure that allows easy replacement of ring rolls is shown. This is a roll mill equipped with a large number of roll units and eccentric cylinder-type pitch adjustment devices in the roll units. The roll unit has the same meaning as the roll fitting described above. The above-mentioned case is formed of a coupling type case that can be combined and disengaged freely, and is composed of a first case and a second case. A split bearing portion is formed on a joint surface of the first casing and the second casing. The shaft portion of each roll unit is supported by the first and second housings in the bearing eccentric cylinder which joins the two split bearing portions.

This steel rolling mill can pull the shaft from the endless roller by pushing and pulling on the end of the shaft. Therefore, the ring roller that has been free is replaced with a new ring roller, and then the roller shaft is inserted into the ring roller to tighten the connection. In addition, the roll fitting has a mechanism for tightly coupling and releasing the tight-fitting of the annular roller and the roller shaft by oil pressure, forming a pushing surface with the annular roller installation part on the inner diameter side of the annular roller and the roller shaft, and having It is more suitable to pass the hydraulic piping in the roller shaft from one end of the roller shaft, and to have an oil injection port and a suspension fixture seat at one end of the roller shaft. Because oil pressure is applied from the end of the roller shaft through the roller shaft, the two pushing surfaces can be caused to be closely contacted or separated to perform tight-fit connection or release of the tight-fitting of the roller shaft and the annular roller. In addition, the annular roller installation part of the roller shaft is tightly connected or separated by the pushing surface. Therefore, due to the wedge effect of the pushing surface, the tight fitting connection is stronger and can be smoothly separated.

Description of the invention (7 ) [The best form of implementation of the invention] ~ (Please read the precautions on the back before filling in this page) By using four steel rolls arranged at equal angular intervals around the center of the rolling track and supported by the shell (Hereinafter referred to as a four-roll rolling aluminum steel machine.) The present invention will be described in more detail using an application example. Fig. 1 is a cross-sectional view showing a main part of a structure of a four-roll rolling mill according to the present invention. Figure 1 shows the 1/4 part around the center 16 of the rolling path. Turn the first image around 90 °, 180 °, and 270 ° around the center of the rolling path 16 to obtain the overall image. The roll fitting is formed by installing a ring-shaped roller 2 on the ring-shaped roller mounting portion 1A at the bottom end of the roller shaft 1. The outer peripheral surface of the ring roller 2 is regarded as a work roller surface. Moreover, a push-out surface is formed on the outer peripheral surface of the annular roller installation portion 1A of the engaging portion of the roller shaft 1 and the annular roller 2 and the inner diameter side of the annular roller 2, and the two push-out surfaces are in a state of tight fit and connection. In this example, the outer peripheral surface of the annular roller mounting portion 1A is a male push-pull surface that is uphill at the top of the surface roller shaft 1. The inner diameter side of the annular roller 2 is fitted with a pushing sleeve 3 having an inner diameter side which can be slidably connected to the female pushing surface of the aforementioned male pushing surface. The tight-fit connection and release of the tight-fitting of the roller shaft 1 and the ring-shaped roller 2 are carried out tightly or separately by, for example, applying oil pressure to the male-female pushing surface. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. The ring-shaped roller installation part 1 A on the bottom end side of the roller shaft 1 is provided with bearings 4 A and 4 B, and one bearing on the top side is also provided with a bearing 5. The bottom side bearings 4 A and 4 B are supported by the housing 8 through the lower eccentric cylinder 6 A, while the top side bearings 5 are supported by the housing 8 through the upper eccentric cylinder 6 B and the thrust adjusting screw 7. In addition, the end of the front-end-side roller shaft is exposed outside the casing 8. The lower eccentric cylinder 6 A supports the bearings 4 A and 4 B, while the upper eccentric cylinder 6 B supports the bearings 5 so as to be slidable in the direction of the roller axis. And the paper size on the lower side applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) -10- 480194 A7 _______ B7 V. Description of the invention (8) (Please read the precautions on the back before filling this page) Eccentricity The cylinder 6 A and the upper eccentric cylinder 6 B are further supported by the casing 8 so as to be rotatable around the shaft. If the lower eccentric cylinder 6 A is rotated around the self-shaft circumference, the center of the roller shaft 1 can be rotated around the center of the lower eccentric cylinder 6 A. The same is true for the upper eccentric cylinder. If so, the eccentric cylinder 6 can cause the roller shaft 1 to move in a direction orthogonal to the shaft, and is used to adjust the distance between the center of the endless roller 2 and the center 16 of the rolling path, that is, the roller distance. The lower eccentric cylinder 6 A and the upper eccentric cylinder 6 B are connected at variable intervals. And the bearing 5 is screwed to the upper eccentric cylinder 6 B by the locking screw 9. In this structure, the outer diameters of the bearings 4 A and 4 B are set to be less than the inner diameter of the pushing sleeve 3 so that the pushing surfaces of the roller shaft 1 and the annular roller 2 are separated from each other. And the screwing of the locking screw 9 is released and the roller shaft 1 is moved in the direction of the roller shaft. As a result, the roller shaft 1 can be pulled out from the endless roller 2. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. The thrust adjustment screw 7 is supported by the upper eccentric cylinder 6 B around the shaft inside the inner peripheral surface. The thrust adjusting screw 7 is screwed and screwed to the screw seat 10 of the housing 8 on the outer peripheral side. And the thrust adjusting screw 7 卡 is locked on the screw seat 10 by the clamping bolt 11. Therefore, by loosening the clamping bolts 11 and turning the thrust adjusting screw 7, the position of the roll fitting in the direction of the roll axis can be adjusted. Fig. 2 is a cross-sectional view showing the hydraulic pressure applying means for the pushing surface. The oil supply path 12 is from the oil filling port 1 2 A which is opened on the end surface of the roller shaft, and then passes through the inside of the roller shaft to the oil outlet port 12 2B. The end of the roller shaft with the oil filling port 1 2A exposed is exposed to the outside of the housing, and a circumferential groove 22 is provided in the exposed roller shaft portion. The circumferential groove 22 is a suspension fixture receiving portion for suspending the roller shaft. The oil outlets 1 2 B are open at the pushing surface of the ring roller installation section 1 A. -11-This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) 480194 A7 B7 Ministry of Economy Printed by the Intellectual Property Bureau's Consumer Cooperatives V. Invention Description (9) In the initial state, the two push faces are in close contact, when high pressure oil is injected from the oil injection port 1 2 A, that is, due to the oil pressure of the oil outlet 1 2 B The inner diameter of the push sleeve 3 is enlarged within the elastic deformation. Moreover, the repulsive force between the two pushing surfaces is promoted by the reaction of the enlarged inner diameter, so that the two pushing surfaces are easy to separate. Then, the oil pressure is reduced. When the inner diameter of the push-pull sleeve 3 returns to normal, the two push-pull surfaces are separated. As a result, when the roller shaft 1 is pulled out from the casing, it can be pulled out from the endless roller 2. In addition, when the initial state is that the two pushing surfaces are separated, the roller shaft 1 is pushed into the casing and the high pressure oil is pushed by the thrust force that can overcome the repulsive force of the two pushing surfaces, so that the roller shaft 1 can enter the relatively oil The smaller diameter side of the push sleeve 3 with the enlarged inner diameter. When the oil pressure is lowered until the inner diameter of the pushing sleeve 3 returns to normal, a firm state of the two pushing faces can be obtained. If so, the steel strip rolling mill of the present invention can perform tight-fit connection and release of the tight-fitting of the endless roll and the roller shaft in the casing. This means that only the ring roller can be replaced without disassembling the housing. Next, the ring roll exchange method of the above-mentioned four-roll rolling mill will be described. This method is performed by the following steps, and the situation is shown in Fig. 3 (a) to l. Preparation of the casing (1) The casing is placed on the replacement table by a crane.

Description of the invention 〇3) 〇 (Please read the precautions on the back before filling this page) High pressure oil is injected from the high pressure oil filling port 1 2 7 of the oil supply path 1 1 7. The maximum injection pressure of high-pressure oil is about 2000 k g f / c m2 (196 MPa), and it is better to set the deformation of the pushing surface to the pressure in the elastic domain. When high pressure oil is injected, the rod body 1 1 6 is pressed into the roller shaft 10 1. After the close cooperation between the endless roller 10 and the roller shaft 1 0 1 is released, the rod body 1 1 6 is to lift the roller shaft 1 0 1. In order to press and lift in this way, it is better to set the driving pressure of the rod 116 of the hydraulic actuator 118 to a pressure of 700 kgf / cm2 (69 MPa) at the maximum which can smoothly move the roller shaft. The method of holding the nozzle at the protruding end of the rod body 1 16 may be performed by screwing or the like. However, as shown in this example, a spring seat such as a spring or a fluid pressure actuator can be used to hold it. It is more effective because the impact of high-pressure oil injection can be mitigated more effectively. Printed by the Employees' Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. If it is difficult to directly push the end of the roller shaft with the protruding end of the rod, it is sufficient to use a pushing jig for transmitting force. The press-fit ring 1 19 in Fig. 4 (b) is an example. At this time, it is more appropriate to provide a pressing jig holder for engaging the pressing jig at the protruding end of the rod body 1 16. For the press-in ring 1 1 9, the ring-embedding hole 1 2 1 is equivalent to pressing the clamp seat. The roller suspension device related to the present invention must have a suspension jig that can be engaged with a suspension jig holder provided at the end of the roller. In Fig. 4 (a), a circumferential groove 1 2 2 is shown by the suspension fixture base, and a grooved jaw plate 1 2 3 is shown by the engaged fixture. By means of the suspension jig, the roller shaft 1 〇 1 which is released from the tight fit connection with the endless roller 10 2 can be driven by oil pressure 1 8-16 -16- This paper size applies to China National Standard (CNS) A4 specifications ( 210 X 297 mm) 480194 A7 B7 V.
