Description

Technical Field

[0001] This utility model relates to a device for preventing tooth skipping on a small-sized round steel cooling bed, belonging to the field of steel rolling production technology. Background Technology

[0002] During the production of small-diameter round steel (φ16.8~φ25), each multiple length slides down the lifting skirt plate at a speed of up to 13m / s. Moreover, due to its light weight, when the rolled material touches the guide plate, it is very easy to bounce back and fall into the straightening grid in many places. In addition, due to the fast production and rolling rhythm and the automatic steel receiving on the cooling bed, once the teeth are misaligned, they cannot be effectively handled, resulting in a large number of quality problems in the rolled material. This leads to a low yield of small-diameter round steel due to the problem of skipped teeth. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a small-size round steel cooling bed anti-tooth jumping device that is easy to operate, prevents tooth jumping, avoids small round steel from sliding into the guide plate and rebounding into the straightening grid, and improves the yield of small-size round steel.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: a small-specification round steel cooling bed anti-skid tooth device, including a base, the base being fixed to the input roller protective plate, a rotating body being hinged to the side of the base, an anti-skid tooth plate being provided on the top of the rotating body, one end of the anti-skid tooth plate being fixedly connected to the rotating body, and the other end being a free end. In the initial state, the free end of the anti-skid tooth plate is located on the outside of the cooling bed; by rotating the rotating body, the free end of the anti-skid tooth plate is placed on the guide plate, and the anti-skid tooth plate acts as a blocking device for the rolled material being pushed into the straightening grid by the stepping.

[0005] The base is L-shaped, and the base plate is fixed to the top of the input roller protection plate by bolts. The side plate of the base has a pin hole and a limit thread hole.

[0006] The anti-jump toothed plate is Z-shaped and is made of thin plate.

[0007] The rotating body has a rotating hole, and the pin passes through the rotating hole and the pin hole, so that the rotating body can rotate around the pin. The bottom of the rotating body has an arc groove. When the anti-skid plate is placed on the guide plate, the arc groove corresponds to the limiting threaded hole, and the limiting bolt passes through the arc groove and is screwed into the limiting threaded hole.

[0008] Compared with existing technologies, the advantages of this utility model are as follows: A device for preventing tooth skipping on a cooling bed for small-diameter round steel bars involves a rotating body that flips the anti-tooth-skipping plate so that its free end rests on the guide plate in an online state. The rotating body is locked to the base by limiting bolts, ensuring stable and non-rebounding sliding into the guide plate at different lengths and speeds. This application is easy to operate, prevents tooth skipping, avoids small round steel bars from rebounding and falling into the straightening grid after sliding into the guide plate, and improves the yield of small-diameter round steel bars.

Detailed Implementation

[0010] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0011] like Figure 3 , 4As shown, this embodiment of a small-sized round steel cooling bed anti-skid tooth device includes an L-shaped base 2.1. The base plate of the base 2.1 is fixed to the top of the input roller guard plate 1 by bolts. The side plate of the base 2.1 has a pin hole and a limiting thread hole. The side plate of the base has a rotating body with a rotating hole on its side. The pin 2.3 passes through the rotating hole and the pin hole, so that the rotating body 2.2 is hinged to the base 2.1 and can rotate around the pin 2.3. The top of the rotating body 2.2 is provided with an anti-skid tooth plate 2.5. One end of the anti-skid tooth plate 2.5 is fixed to the top of the rotating body by bolts, and the other end is a free end. In the initial state, the free end of the anti-skid tooth plate is located outside the cooling bed, and the anti-skid tooth plate is in the offline state. When the rotating body is rotated around the pin, the anti-skid tooth plate rotates synchronously. At this time, the anti-skid tooth plate is located at the bottom of the rotating body, and the free end of the anti-skid tooth plate rests on the guide plate, and the anti-skid tooth plate is in the online state. An arc-shaped groove is formed on the bottom surface of the rotating body. After the rotating body rotates to its position, the arc-shaped groove corresponds to the limiting threaded hole. The limiting bolt 2.4 passes through the arc-shaped groove and is screwed into the limiting threaded hole, so that the rotating body is locked on the base. The anti-skid plate 2.5 rests on the guide plate 3 while retaining sufficient toughness. It can both meet the requirement of the moving rack 5 to step-by-step lift the rolled material 6 into the straightening grid 4 and ensure that the rolled material slides smoothly into the guide plate, preventing the rolled material 6 from rebounding and falling into the straightening grid 4.

[0012] The anti-skid plate is a rectangular thin plate that is bent into an approximate "Z" shape.

[0013] like Figure 1 As shown, when producing small circles, the rotating body is rotated so that the free end of the anti-skid tooth plate rests on the guide plate, and then the rotating body is locked to the base by the limit bolt.

[0014] like Figure 2 As shown, when producing large circles, remove the limit bolts and rotate the rotating body in the opposite direction to flip the free end of the anti-skid tooth plate to the offline position.

[0015] Based on the actual tooth skipping situation on site, anti-tooth skipping devices 2 are installed in multiple locations on the input roller protective plate in advance. When producing small round steel with a diameter of φ16.8~φ25, the rotating body is flipped so that the anti-tooth skipping plate flips onto the line. The rotating body is locked to the base by the limit bolts to ensure that it slides into the guide plate at high speed and stably without rebounding at different multiples of length.

[0016] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
