Description

Improved tooth structure at tail end of movable rack of small rod cooling bed

Technical Field

The utility model relates to the technical field of metallurgical machinery, in particular to a small rod cold bed movable rack terminal improved tooth structure.

Background

A step rack type cooling bed for hot rolling phi 14-phi 50 deformed steel and high-quality small rods is an important device on a small rod production line, and comprises main devices such as a cooling bed input roller way, a cooling bed transmission device, a rack beam assembly, an alignment roller way, a cooling bed output roller way and the like. The finished rolled piece moves on the bed surface and drives the moving rack to realize the rising and forward movement of the finished rolled piece through the eccentric wheel. After the deformed steel bars and the small bars are rolled and formed by a finishing mill group, the deformed steel bars and the small bars are sheared by a double-length flying shear and then enter a cooling bed input roller way, a finished product rolled piece is thrown onto a straight throwing plate through the lifting of a braking plate, then a movable rack starts stepping action, the finished product rolled piece moves towards the tail end of the cooling bed (the side of the cooling bed output roller way) step by step, and the finished product rolled piece is straightened and cooled on the cooling bed. The finished rolled piece is subjected to single rolling and splitting rolling according to production specifications. When the rolled piece moves to the tail end of the cooling bed, the moving rack supports the rolled piece, and the rolled piece is transversely placed on a distribution chain of the cooling bed output device, the distribution chain needs to move for a certain distance to take the rolled piece away from the rack, and a placement space is also left for the next group of rolled pieces.

The production line of small bars in China at first has low yield, only single rolling and small-specification splitting rolling are carried out, and the pitch of the cold bed rack is generally 80 mm. At present, with the high-speed development of the society, the demand is continuously increased, the requirement on the production line yield is higher and higher, so the varieties of slitting rolling are more and more, the pitch 80mm cannot meet the production requirement, so the pitch is increased to be 110mm, the requirement on slitting rolling is met, but the efficiency of a cooling bed is greatly improved after the pitch of a rack is increased, but when a movable rack at the tail end of the cooling bed unloads, the tooth profile has a bending phenomenon on a finished product rolled piece, and the product quality is influenced.

In order to solve the technical problem, the utility model provides a following technical scheme: a tooth structure is improved at the tail end of a movable rack of a small rod cooling bed, and comprises a chain, a fixed rack, a movable rack, a chain wheel, an output shaft and a mounting flange, wherein the chain wheel drives the chain, a first inclined plane is arranged at the tail end of the movable rack, and a second inclined plane is arranged at the tail end of the fixed rack; the first inclined plane is provided with a lowest point, the lowest point extends downwards to form a vertical section, and the lowest point is always positioned below the chain.

Furthermore, the inside of sprocket cup joints fixed connection with the one end of output shaft.

Furthermore, the center of one side of the chain wheel is fixedly connected with one side of the mounting flange through a bolt.

Further, the chain wheel is connected with the chain in a meshed mode.

Further, the angle of the first inclined plane is 30-35 degrees.

Further, the angle of the second inclined plane is 30-35 degrees.

Compared with the prior art, the utility model discloses the beneficial effect who reaches is: the utility model discloses an improve the support effect on tooth structure through the first inclined plane of moving the rack, hold up the rolled piece and put when the fixed rack is terminal, the rolled piece is along the second inclined plane to gliding to the chain on, when moving the rack and hold up a set of rolled piece down, first inclined plane will go up a set of rolled piece and hold up once more and promote to the cooling bed output side, first inclined plane is moved all the time in the rolled piece below, avoids appearing the phenomenon that the rolled piece was bent to the moving rack to product quality has been improved.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: the utility model provides a stub cold bed moves rack end and improves tooth structure, includes chain 1, fixed rack 4, moves rack 5, sprocket 6, output shaft 7 and mounting flange 8, and the inside of sprocket 6 cup joints fixed connection with the one end of output shaft 7, is favorable to utilizing the rotation of output shaft 7 to transfer the rotation of sprocket 6. The center of one side of the chain wheel 6 is fixedly connected with one side of the mounting flange 8 through a bolt, and the chain wheel 6 is meshed with the chain 1, so that feeding is facilitated. The two sides of the chain wheel 6 are respectively provided with a fixed rack 4 and a movable rack 5.

The tail end of the movable rack 5 is provided with a first inclined plane 2 which can support a rolling piece. And a second inclined plane 3 is arranged at the tail end of the fixed rack 4 and is used for bearing a rolled piece. The first inclined plane 2 has a lowest point 21, and the lowest point 21 extends downwards to form a vertical section 22, wherein the lowest point 21 is always located below the chain 1. The angle of the first inclined plane 2 and the second inclined plane 3 is 30-35 degrees, and the rolled piece can move towards the inclined planes within the angle range in a labor-saving manner.

As shown in fig. 2, the moving rack 5 is schematically shown at the highest position X and the lowest position Y. When the moving rack 5 is located at the highest position X of the motion track, the lowest point and the vertical section of the first inclined plane 2 are located at the bottom end of the chain 1, when the moving rack 5 supports a rolled piece and places the rolled piece at the tail end of the fixed rack 4, the rolled piece slides downwards along the second inclined plane 3 to the chain 1, when the moving rack 5 supports a next group of rolled pieces, the first inclined plane 2 supports the previous group of rolled pieces again and pushes the previous group of rolled pieces to the output side of the cooling bed, the first inclined plane 2 always acts below the rolled piece, the phenomenon that the moving rack 5 bends the rolled piece is avoided, and therefore product quality is improved.
