Abstract
A puller resetting device on a shifting bearing block of a twin roller caster comprises a support seat fixed on a bottom plate of a casting roller set of the twin roller caster by a bolt. Three shaftsleeve installation holes are arranged on a support plate of the support seat and are respectively provided with a shaft sleeve with an internal thread. The shaft sleeves are fixed on the support plate of the support seat by nuts. Each shaft sleeve is connected with an elastic puller device by a thread. The elastic puller device comprises a casing with one end closed and the other end opened. Thecasing is provided with a disk spring and a mandril inside. An external thread is processed on the excircle of the mandril and is connected with the internal thread of the shaft sleeve. A plane bearing is arranged on a round table at one end of the mandril and is fixed on the round table by a plane gland nut which is put against the disk spring in the casing.
Description
Technical field
The present invention relates to a kind of twin-roll cast-rolling mill, particularly a kind of resetting means that holds out against that is arranged on twin-roll cast-rolling mill moving shaft holder back.
Background technology
Existing casting roller of twin roller caster unit as shown in Figure 1, it comprises a base plate 4, end both sides at base plate 4 are respectively equipped with a bearing block 2, and bearing block 2 is fixed on the base plate 4 by screw, are provided with a casting roller 1 in the dead eye of two fixing bearing blocks 2.Be respectively equipped with a moving shaft holder 6 in the other end both sides of base plate 4, moving shaft holder 6 is provided with four bar shaped spacing holes 3, be provided with the position-limitting pin 7 of a threaded head in each bar shaped spacing hole 3, by stop screw 7 moving shaft holder 6 is fixed on the base plate 4, moving shaft holder 6 can move back and forth along position-limitting pin 7, be provided with a casting roller 5 in the dead eye of two moving shaft holders 6, like this, casting roller 5 also can be along with moving shaft holder 6 moves back and forth.The roll-force of twin-roll cast-rolling mill is to provide by the resetting means that holds out against that is installed in moving shaft holder 6 back, and the existing resetting means that holds out against generally all is to adopt hydraulic pressure to hold out against resetting means or the pneumatic resetting means that holds out against
Twin-roll cast-rolling mill is in the process of rolling strip steel plate, molten steel contacts the generation crystallization with casting roller surface in bath, the crystallization thickness of molten steel on casting roller surface is subjected to the influence of various factors such as rotary speed of liquid steel level height in the bath, casting roller, and crystallization thickness is all different.When the crystallization thickness of molten steel on casting roller surface is increased by the influence of various factors crystallization thickness such as rotary speed of liquid steel level height in the bath, casting roller moving shaft holder is passed backward, behind the rotary speed recovery normal crystallization thickness of adjusting liquid steel level height, casting roller in the bath, moving shaft holder need be passed forward rapidly, return to original position, guarantee the thickness requirement of rolling strip steel plate.But the existing hydraulic pressure that is installed in the moving shaft holder back holds out against resetting means or the pneumatic resetting means that holds out against, and can not make a response rapidly, and moving shaft holder is passed forward rapidly, returns to original position.At this moment, the rolling strip steel plate that comes out will thickening.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency of prior art and a kind of puller resetting device on shifting bearing block of twin-roll cast-rolling mill is provided.
Technical scheme of the present invention is: a kind of puller resetting device on shifting bearing block of twin-roll cast-rolling mill, it comprises one by being bolted to the supporting seat on the casting roller of twin roller caster unit base plate, on the gripper shoe of supporting seat, be provided with three axle sleeve installing holes, in three axle sleeve installing holes, be respectively equipped with a tapped axle sleeve, axle sleeve is fixed on by nut on the gripper shoe of supporting seat, on each axle sleeve by the elasticity holding device that is threaded.The elasticity holding device comprises that one one end seals the sleeve pipe of an end opening, be provided with a disk spring and a push rod in the sleeve pipe, the cylindrical of push rod is processed with external screw thread, the external screw thread of push rod is connected with the internal thread of axle sleeve, on the round platform of push rod one end, be provided with a plane bearing, plane bearing is fixed on the round platform of push rod by a plane clamp nut, and the plane clamp nut withstands on the interior disk spring of sleeve pipe.
The present invention compared with prior art has following characteristics:
1, when the crystallization thickness of molten steel on casting roller surface is increased by the influence of various factors crystallization thickness such as rotary speed of liquid steel level height in the bath, casting roller moving shaft holder is passed backward, behind the rotary speed recovery normal crystallization thickness of adjusting liquid steel level height, casting roller in the bath, the resetting means that holds out against provided by the invention can be made a response rapidly, moving shaft holder is passed forward rapidly, return to original position, guarantee the thickness requirement of rolling strip steel plate;
2, can adjust the size of roll-force as required, easy to adjust.
Below in conjunction with the drawings and specific embodiments detailed structure of the present invention is further described.
