Abstract

PURPOSE:To eliminate the need for devices that move rolls back and forth on the outside part by fitting a pair of roll bearing cages which support a pair of rolls freely rotatably to a yoke, making one of said cages freely slidable with respect to the yoke, and projecting the plungers in the cylinder chambers inscribed on the inside circumferences of said yoke to the outside circumference of the roll bearing cage. CONSTITUTION:A pair of upper and lower roll bearing cages 4, 12 which support rolls 5, 14 freely rotatably are fitted to a yoke 3, and the cage 12 is made freely slidable with respect to the yoke 3. Annular cylinder chambers 25, 26 are formed on the inside circumferential surface of the yoke 3 with which the outside circumferential surface of the cage 12 contacts slidingly. Annular plungers 11 which partition the cylinder chambers to two are projected on the outside circumference of the cage 12 in sliding contact with the inside circumferential surfaces of the chambers 25, 26. Further oil passages for moving the roll 14 supported by the cage 12 upward by feeding and discharging of pressure oil to and from the chambers 25, 26 are provided.

Description

[Detailed Description of the Invention] This invention provides a variable caliper four that allows the caliper to be set arbitrarily and can be made smaller! II 0 compression material O A dog poon O that becomes a large width (the edge of the slab OA is raised)
Tateya press machine Kll to reduce and prevent twisting! The commonly used cariparol is 11NIWJK T151ca-ko 14*
It was effective only for rolling #0 with a constant reparing width W and a constant plate thickness. Therefore, the rolling #0 to be processed [II where the rhino changes]
I had to replace K-Iru 01. Therefore, a caliper μm in which the caliper width W can be arbitrarily varied was devised. 4184HE has been shown to be %A, so Hiro, I decided to arbitrarily determine one of the Caliper rolls, which are divided into the upper roll and the lower roll, as the exclusive excitation for the Rinj5 Qu. - See, but here is the O$ moving machine - Since the roll itself is provided as a screw mechanism, it is extremely difficult to change the 0 caliper width online [1
It is mm. In addition, in the case shown in JilKil 52-18 Jikkin, the roll zero movement device is fixed to the housing of the outer part of the roll. *At the time of IIJ, the push beam received a moment due to the vertical force acting on each Q-le 07 lunge that makes up the caliper, which caused problems such as the reliability of the device being affected (or the device becoming unstable). The confrontation of 0 and 19 rolls that result in this requires the effort of having to remove the push beam from the housing.Therefore, the author @sha, as mentioned above, took a deep breath and approached and departed relatively. The upper p-ru and the lower roll change the kariba.
As a device for driving at least one of the WJ variable rolls, a roll bearing cage is used as a 1-run resistance. ! The purpose of this machine is to increase the volume of the equipment by layering and increasing the volume of the equipment.The present invention, which combines these purposes, has a pair of upper and lower rolls that are interlocked and relative to each other. ! I In variable caliber rolls that move toward and away from each other, a pair of upper and lower roll bearing cages that rotatably support these rolls are fitted into a yoke, and at least one of the roll bearing cages is moved relative to the yoke in a direction parallel to the axis of the roll. The outer circumferential direction of one of the roll bearing cages slides in sliding contact to form a cylinder chamber having a shape of four circumferences, and the inner circumferential direction of this cylinder chamber is in sliding contact with the outer circumferential direction of the cylinder chamber. An annular plunger that divides the cylinder into two is centrally installed on the outer periphery of one of the roll bearing cages, and j! An oil passage is provided in order to excite the roll supported by one of the roll bearing cages by supplying and discharging O-pressure oil to the cylinder chamber which is partitioned into two parts. It is characterized by a 7-ring cage with 111 features.

The present invention will be detailed below based on an embodiment shown in ll-.

First, the pressure from the I& section passes through the oil passage 27 and reaches the lower cylinder 1.
When 12sK is supplied, the upper roll 14 rises together with the upper roll bearing cage 12, widening the inside of the variable valve CO formed by the upper roll 14 and the lower roll 5. Conversely, from the oil passage 28 to the upper cylinder When wL2・IIc oil is supplied, the upper roll 14 lowers and narrows in the inside of C/(C).In addition, it is fixed to the yoke 3 via the bracket 29, and the movement amount of the upper roll bearing cage 12 is fixed. The upper end of the upper roll 14 is connected to the upper roll bearing cage/12 and the detector 30 for detecting the
It is integrally fitted into a spindle coupling 31 connected to the drive prosthesis.

On the other hand, a pair of upper and lower adjustment screws 32 are connected to the roller 3 to reciprocate the roll in the width direction of the rolled material 1 in accordance with the amount of reduction in the width of the rolled material 1. Therefore, pressurized oil is discharged into each of the cylinder chambers 25 and 26, which are composed of the 7 cylinder cylinder 1G, the upper roll, the bearing cage 12, and the seal cage 23, and the upper roll l')
to raise and lower. Its vertical position is detected by the detector 30, and by controlling the amount of oil, the amount of movement of the upper roll 14 is adjusted to obtain an arbitrary caliber width according to the thickness of the rolled material 1O1. Although the cylinder IOK is provided at 27°28, it is also possible to provide an upper roll bearing cage 124'C.

Next, another embodiment of the present invention is shown in the 31st embodiment with the caliper width slightly narrowed. ! #IL is illustrated by FIG. 5, which shows a cross-sectional view similar to il, and FIG. I will only explain the parts that are different from the example, and omit the explanation of the same parts. In the above-mentioned nine embodiments, the stile,
The amount of Ifl of the upper roll 110 was arbitrarily controlled in analog mode by the detector 30, but in this embodiment, the ti, sR levels can be digitally adjusted. As shown in Figure 4, three locking rod holes 33 are bored in the locking key 13 along its length. This cell has 9 locking keys, 13 keys, and a mutual K180j [2 partitions are provided. The yoke 3Krj has a communication hole 34 facing each of the lock rods 2c33 of these 19 stop keys 13.A reciprocating lock rod 35 that can penetrate through the communication hole 34 into the lock rod hole 33 is provided. , the upper roll bearing m1ll is connected to the hydraulic cylinder 36 attached to the communication hole 34 of the yoke 3. Therefore, the desired one of the three O-lock holes 3 is aligned with the communication hole 34. Self-lock #35 [If you insert it, the upper roll 14 will be positioned and fixed.The more 33 you provide for this lock rod, the more you can adjust the width in many steps. In this example, the younger sister, -9 stop key 1
Of course, it is also possible to provide the lock rod 33 directly on the upper roll bearing cage 12. In that case, the communication hole 34 that guides the opening ylr rod 35 should be inserted between the upper roll bearing cage 12 and the communication hole 34. It is preferable to provide two from both sides of the 1C yoke 3 so that they face each other.

Further, in each of the embodiments, the upper roll 14 is movable, but the lower roll 5 may be movable upwards, or the other roll may be movable. History 1C cylinder 10 used iii
