Description

Technical Field

[0001] This utility model relates to a universal rolling mill roll surface steel adhesion cleaning device, belonging to the technical field of steel rail production equipment in the metallurgical industry. Background Technology

[0002] During the production of steel rails, iron oxide scale easily adheres to the surface of the rolls. The iron oxide scale adhering to the roll surface is pressed into the rolled piece, affecting product quality. Utility Model Content

[0003] The purpose of this invention is to provide a universal rolling mill roll surface steel adhesion cleaning device, which can clean the iron oxide scale adhering to the roll surface online, prevent it from being pressed into the rolled workpiece, ensure product quality, and solve the problems existing in the background technology.

[0004] The technical solution of this utility model is:

[0005] A universal rolling mill roll surface steel adhesion cleaning device includes a base, scraper arms, scraper brackets, scrapers, base bolts, and scraper bracket bolts. The base is installed and fixed on the guide box of the universal rolling mill guide. There are two scraper arms. One end of the two scraper arms is installed on the base through the base bolts, and the other end of the two scraper arms is connected to the scraper bracket through the scraper bracket bolts. The scraper bracket is provided with two scrapers that match the roll pass shape.

[0006] The two scrapers on the scraper support that match the roll die are U-shaped.

[0007] The two scrapers on the scraper bracket that match the roll die are fixed to the scraper bracket by scraper bolts.

[0008] The scraper bracket is provided with a limiting post, and the scraper arm is provided with a limiting claw that cooperates with the limiting post.

[0009] A spring frame is provided in the middle of the scraper arm, and a spring is provided between the spring frame and the scraper bolt.

[0010] The beneficial effects of this invention are: it can clean the iron oxide scale adhering to the surface of the rolls online, preventing it from being pressed into the rolled product and ensuring product quality. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and examples.

[0019] See attached document Figure 1-6 A universal rolling mill roll surface steel adhesion cleaning device includes a base 1, scraper arms 2, scraper brackets 3, scrapers 4, base bolts 5, and scraper frame bolts 6. The base 1 is installed and fixed on the guide box of the universal rolling mill guide. There are two scraper arms 2. One end of the two scraper arms 2 is installed on the base 1 through the base bolts 5, and the other end of the two scraper arms 2 is connected to the scraper bracket 3 through the scraper frame bolts 6. The scraper bracket 3 is provided with two scrapers 4 that match the roll pass shape.

[0020] In this embodiment, refer to the appendix Figure 1-6 The cleaning device includes a base 1, scraper arms 2, scraper brackets 3, scraper 4, base bolts 5, scraper frame bolts 6, scraper bolts 7, limiting claws 11, spring frames 12, and limiting posts 15. The two bases 1 are respectively installed and fixed on the guide boxes of the universal rolling mill guides. The two scraper arms 2 are connected to the two bases 1 by the base bolts 5. The scraper brackets 3 are connected to the two scraper arms 2 by the scraper frame bolts 6. The two scraper 4 are fixed to the scraper brackets 3 by the scraper bolts 7. The ends of the scraper frame bolts 6 are spring-tensioned in the middle of the scraper arms 2, and the scraper 4 is pressed against the roll by the torsion spring.

[0021] The gap between the two bases 1 is 20-50mm wider than the width of the scraper arm 2, and their centers are on the center line of the roll. The base bolts 5 and the bolt holes are clearance fit, with a clearance of 0.5-3mm. The base bolts 5 are secured with two self-locking nuts to ensure that the bracket can move with the position of the roll.

[0022] The connecting bolt holes of the scraper bracket 3 and the scraper arm 2 are round bolt holes 13 on one side and elliptical bolt holes 10 on the other side. The length of the elliptical bolt hole 10 is 5-15mm longer than that of the round bolt hole 13. A tension spring is used to pull the bolt on the elliptical hole side to achieve the contact between the two scrapers 4 and the roller on opposite sides.

[0023] The scraper arm 2 is curved with an angle of about 150-170°. The end of the scraper arm 2 is designed with a limiting claw 11 that cooperates with the limiting post 15 on the scraper bracket 3 to prevent the scraper bracket 3 from flipping. A tension spring is installed at a certain distance on the side of the elliptical hole.

[0024] The scraper 4 is designed according to the roll pass shape, and its width is increased by 0.5-1mm compared to the roll pass shape. Under the action of lateral tension, the two scrapers 4 contact the roll diagonally.
