Description

Technical Field

[0001] The utility model relates to the technical field of rough rolling production, in particular to a transition guide groove between rough rolling machine frames. Background Art

[0002] The rough rolling mill is an important part of the rolling mill in the steel wire workshop. The distance between the rough rolling mill frames is relatively long. When the red steel passes through the rolling mill, a transition device needs to be set between the two rolling mills to facilitate the red steel to enter the next rolling mill smoothly and participate in the rolling smoothly.

[0003] A bell-mouth transition is usually used between the original two rough rolling mills. However, when the red steel passes through the bell-mouth, the iron oxide on the red steel will fall inside, causing iron oxide accumulation. At the same time, the bottom of the red steel will be scratched during transportation, causing scars and pits on the surface of the finished wire. There is also a gap between the bell-mouth and the outlet of the previous mill. When the head of the red steel bends, the bell-mouth will be overturned, causing a steel stacking failure. Utility Model Content

[0004] The purpose of the utility model is to propose a transition guide groove between rough rolling mill frames, which solves the problem of easy accumulation of iron oxide in the bell mouth between the existing rough rolling mill units, and at the same time reduces scarring and pitting on the surface of the finished wire rod caused by abrasions on the bottom of the red steel, thereby greatly improving production efficiency and production quality.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A transition guide groove between roughing mill stands, used for conveying steel between two roughing mill stands, comprises:

[0007] A guide groove, wherein the bottom of the guide rail is provided with an opening for allowing the iron oxide on the steel to fall off;

[0008] A supporting wheel is rotatably disposed in the opening and is used to transport the steel;

[0009] The bell mouth is connected to any end of the guide groove to guide the steel.

[0010] Preferably, it further comprises: a mounting frame connected to the bottom of the guide groove and located at the opening, and the supporting wheel is rotatably connected to both sides of the mounting frame via a rotating shaft.

[0011] Preferably, the distance between the highest point of the supporting wheel and the bottom of the guide groove is 1-3 cm.

[0012] Preferably, the length of the opening is greater than the diameter of the supporting wheel.

[0013] Preferably, the bell mouth comprises:

[0014] A bottom plate connected to the bottom of one end of the guide groove, and the bottom plate is tilted downward at a certain angle in a direction away from the bottom plate;

[0015] The two side plates are respectively connected to the two sides of the guide groove, and along the direction away from the bottom plate, the two side plates are extended outward at a certain angle.

[0016] Preferably, the installation frame is through-connected from top to bottom.

[0017] Beneficial effects of the utility model:

[0018] 1. The utility model provides a supporting wheel on the guide groove, and the supporting wheel matches the opening, so that during the transportation of the red steel, the iron oxide on the red steel can fall downward through the opening, preventing the iron oxide from accumulating inside the guide groove. At the same time, the rotation of the supporting wheel prevents the bottom of the red steel from contacting the bottom of the guide groove, reducing scarring and pitting on the surface of the finished wire due to scratches on the bottom of the red steel, thereby greatly improving the production efficiency and production quality.

[0019] 2. The utility model provides a bell mouth on the guide groove, and the side plates on the bell mouth are expanded outward at a certain angle and the bottom plate is tilted downward at a certain angle, so as to guide the red steel, prevent the bell mouth from being overturned when the red steel head is bent, causing steel stacking failure, and improve production efficiency.

[0024] The following is a further description of the method of use of the present invention in conjunction with the accompanying drawings and specific implementation methods.

[0025] like Figure 1 and Figure 2 As shown, a transition guide groove between roughing mill stands is used for conveying steel between two roughing mill stands, comprising:

[0026] The guide groove has an opening at the bottom of the guide rail to allow the iron oxide on the steel to fall off and prevent the fallen iron oxide from accumulating in the guide groove.

[0027] A supporting wheel is rotatably disposed in the opening and is used to transport the steel;

[0028] The bell mouth is connected to any end of the guide groove to guide the steel. When the head of the steel is bent, the bell mouth can guide the steel during the movement to ensure that the steel can smoothly enter the guide groove after contacting the bell mouth, thereby preventing the occurrence of steel piling.

[0029] It also includes: a mounting frame connected to the bottom of the guide groove and located at the opening, and the supporting wheel is rotatably connected to both sides of the mounting frame through a rotating shaft.

[0030] The distance between the highest point of the support wheel and the bottom of the guide groove is 1-3 cm, so that the friction between the steel and the bottom of the guide groove can be reduced as much as possible during the movement of the steel, thereby preventing the bottom of the steel from being scratched and causing scarring and pitting on the surface of the finished wire product.

[0031] The length of the opening is greater than the diameter of the supporting wheel, so as to ensure that when the steel moves on the guide groove through the supporting wheel, the iron oxide on the steel can fall downward through the opening, thereby preventing the iron oxide from being accumulated.

[0032] The bell mouth comprises:

[0033] A bottom plate connected to the bottom of one end of the guide groove, and the bottom plate is tilted downward at a certain angle in a direction away from the bottom plate;

[0034] The two side plates are respectively connected to the two sides of the guide groove, and along the direction away from the bottom plate, the two side plates are extended outward at a certain angle.

[0035] The installation frame is penetrated from top to bottom and is used for the falling of iron oxide.

[0036] Working process: When the red steel comes out of the rough rolling mill, the head of the red steel will enter the bell mouth and be guided by the bell mouth. As the red steel moves, it will contact with the supporting wheel in the guide groove and move on the supporting wheel. The supporting wheel will lift the red steel and transport it from the guide groove to the next rough rolling mill. At the same time, when the red steel moves, the iron oxide on the red steel will fall off and fall from the opening to prevent the accumulation of iron oxide.

[0037] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
