In order to achieve the above object, the present invention provides a speed control cylinder unit capable of instantaneously reversing the guide structure installed at the exit side of the high-speed rolling rolls 500 and 600 by the impact of the material, and guides and guides the material passage during normal operation. Shock absorbing type for rolling roll protection including shock absorbing spring installation broken type screw part for absorbing shock when bending and tube part acting backward when material bundle grows Provide a cylinder guide device.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

In FIG. 3 and FIG. 5, the cylinder part has the end cover (7) (9) processed by the circular iron plate at the both ends of the cylindrical pipe-shaped cylinder body (1) in a clogged form, and has the screw (8) and the bolt (10). It is assembled closely by). The central portion of the end cover (7) and (9) of the round iron plate is perforated so that the tube (15) can be installed therethrough. The contact portion between the tube (15) and the end cover (7) (9) is a seal (11). This prevents leakage and prevents contact wear.

The upper part of the cylinder body 1 is machined with an air route 3 in the thickness direction of the cylinder body 1 so that the pneumatic pressure in the cylinder body 1 can be moved at a high speed during the reverse operation of the piston 2. The adjusting screw 4 is installed to be able to adjust the flow rate of air.

In addition, when the proper speed maintenance adjustment is not performed during the pneumatic movement of the air route (3) or when a faster piston reverse is required, the adjustment screw (6) of the purge pipe (5) is installed. At the bottom of the end covers 7 and 9 there is a bolt holder 21 for fixing with the base.

The tube part is formed inside the cylinder in the form of a thin cylindrical pipe penetrating through the central hole of the cylinder end cover (7) (9), and the four-sided inlet tube (20) is processed at the tip of the tube (15). The rear end portion is provided with a screw portion 13, and the adjustment nut 12 for adjusting the tube position is coupled thereto. At the far end of the tube 15, the outlet tube 14 for the material outlet is installed without a threaded portion.

In addition, an impact-absorbing spring-loaded cut-off screw portion is located between the four-sided tube 20 and the cylinder end cover 9 on the tip end side of the tube portion.

The screw-type screw part 18 is machined on the outer diameter of the tube 15 to make the tube 15 thin. The fixing ring 17 is installed at the front end of the tube and the movable ring is located at the rear end. (16) is provided, and the shock absorbing spring (19) is provided in the threaded portion (18) between the fixing ring (17) and the movable ring (16). The base 22 is assembled to the rolling mill 200 as a bolt 23.

In operation, as shown in FIG. 1, when the material 100 passes through the rolling rolls 500 and 600, a space is not secured when a bundle is generated in the space between the exit guide 700 and the exit guide 700. And due to the loosening rate of the release clip 1000, the cover 800, the roll is broken and the guide is broken, this phenomenon is caused by the increase in the bundle of material because the space is not secured between the roll and the guide.

The present invention is to solve this phenomenon, as shown in Figures 3, 4, 5, the rolled material 100 passes through the inlet guide 300 and the rolling rolls 500, 600 of the rolling mill 200 When a bunch is generated between the outlet guide and the entrance tube 20 by the material bundle (100-1) as shown in Figure 4 (b) is forced back.

At this time, the piston 15 in the cylinder body 1 reverses, and the tube 15 is reversed while moving the pneumatic pressure in the cylinder through the air route 3. In this case, the end cover 9 and the moving ring 16 are engaged by the reversal of the tube 15. When the force is applied, the spring 19 is compressed and the space between the rolls 500, 600 and the guide is reduced. Since it is secured at a high speed, the rolls 500 and 600 are not broken even when the bundle of materials 100-1 are lumped in a predetermined amount. At this time, the tube 15 is maintained at the maximum backward through the cylinder.

4 (c) is a structure for the case where the bulk of the material bundle 100-1 is maximized when the material shearing machine installed at the front of the finishing rolling process does not work, and the threaded part is processed on the outer diameter of the tube 15. Due to the influence of (18), the thinned tube part is bent or broken by the impact force of the bundle of materials 100-1, thereby showing a state of preventing the cutting and deformation of the rolls 500 and 600 and the cylinder guide. give.

The adjusting nut 12 and the threaded portion 13 installed on the rear end of the tube 15 serve to adjust the installation distance between the rolling rolls 500 and 600 and the entrance tube 20. The screw is adjustable so that the gap can be adjusted at any time during installation or use. Since the gap between the entrance tube 20 and the rolling rolls 500 and 600 plays an important role such as the tip dentability of the rolled material and the friction prevention of the passing material, the standard distance adjustment is essential. In addition, it is configured to adjust to respond to changes in the characteristics, thickness, rolling temperature and the like of the material.

The piston (2) operates between the inlet and outlet holes of the pneumatic movement air route (3) before and after the inner piston (2) of the cylinder body (1), and the purge pipe (5) and adjusting screw (6) It is a device for the case where the air moving speed of the root 3 is slow, and when the backward speed of the piston 2 is required faster, the adjustment screw 6 is opened to speed up the purge speed.

Accordingly, the present invention is due to the configuration, action as described above, during the material rolling between the rolling mill for finishing rolling (500) (600) and the outlet guide during the material defect (defect) and trouble occurs in the occurrence of a material bundle (100) -1) In the event of jamming, it is possible to improve productivity by solving problems such as roll breakage due to bundle and roll contact, friction, and guide shock, production failure due to guide deformation, increased roll usage cost, shortened guide life, and safety accidents. It has the effect of prolonging service life of roll and guide and preventing accidents.
