Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel production equipment, in particular to a device for blowing air in the reverse rolling direction at the rear end of a high-speed wire pinch roll. Background Art
[0002] In a high-speed wire rod production line of a steel mill for producing spiral ribbed bars and round wire products, a pinch roll is usually arranged at the rear end of the high-speed wire rod finishing mill group, and a double-sided guide groove and a diameter gauge are successively arranged at the rear end of the pinch roll. However, in the current conventional equipment layout, due to the short distance between the pinch roll and the diameter gauge, when rolling high-speed wire rod round steel, the cooling water of the pinch roll is easily carried by the high-speed moving rolled piece through the double-sided guide groove to the diameter gauge, thus affecting the accuracy of the diameter gauge detection and even the normal use of the diameter gauge. Therefore, a device is needed to blow the surface of the rolled piece coming out of the pinch roll to remove the attached cooling water on its surface. Content of the Utility Model
[0003] The purpose of the utility model is to provide a device for blowing air in the reverse rolling direction at the rear end of a high-speed wire pinch roll, which can solve the problem that the cooling water of the pinch roll is carried by the high-speed moving rolled piece to the diameter gauge, thus affecting the accuracy of the diameter gauge detection and even the normal use of the diameter gauge.
[0004] To solve the above problems, the technical solution adopted by the utility model is: this device for blowing air in the reverse rolling direction at the rear end of a high-speed wire pinch roll includes a mounting seat provided with a first rolled piece channel. The mounting seat is provided with a jet orifice outside the first rolled piece channel. One end of the mounting seat is provided with a gland. The gland is provided with a rolled piece inlet communicating with the first rolled piece channel. The outer wall of the gland is provided with an annular guiding portion. The outer diameter of the annular guiding portion near one end of the mounting seat is larger than that of the other end. The air outlet direction of the jet orifice faces the annular guiding portion.
[0005] In the above technical solution, a more specific technical solution can also be: the other end of the mounting seat is fixedly connected to the double-sided guide groove, and the double-sided guide groove is provided with a second rolled piece channel communicating with the first rolled piece channel.
[0006] Further, the mounting seat is provided with an air inlet communicating with the jet orifice, and the air inlet is connected to the air source through an air inlet pipe.
[0007] Further, the air inlet pipe is a metal flexible pipe.
[0008] Further, the air source is compressed air.
[0009] Due to adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art:
[0010] The utility model is arranged between a pinch roll and a diameter gauge, where the gland is located on the side close to the pinch roll and the double-sided guide groove is located on the side close to the diameter gauge. When the rolled piece comes out of the pinch roll, the air source is conveyed from the intake pipeline to the air inlet and ejected from the air jet orifice. Under the guidance of the annular guiding part of the gland, the air flow purges the surface of the rolled piece in the reverse rolling direction, removing the cooling water attached to the surface of the rolled piece, preventing the cooling water from being brought to the diameter gauge, enabling the diameter gauge to maintain long-term stable and accurate detection, strengthening the control precision of the product size, and improving the product quality. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 is a schematic structural diagram of the utility model;
[0012] Figure 2 is a schematic position diagram of the utility model during application. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0013] The following further details the utility model in conjunction with the embodiments of the drawings:
[0014] As Figure 1 shown, the air blowing device in the reverse rolling direction at the rear end of the high-speed wire pinch roll includes a mounting seat 1 provided with a first rolled piece channel. The mounting seat 1 is provided with an air jet orifice 2 on the outer side of the first rolled piece channel. One end of the mounting seat 1 is provided with a gland 3. The gland 3 is internally provided with a rolled piece inlet communicating with the first rolled piece channel. The outer wall of the gland 3 is provided with an annular guiding part 3-1. The outer diameter of the annular guiding part 3-1 at the end close to the mounting seat 1 is larger than that at the other end. The air outlet direction of the air jet orifice 2 faces the annular guiding part 3-1.
[0015] The other end of the mounting seat 1 is fixedly connected to a double-sided guide groove 4. The double-sided guide groove 4 is internally provided with a second rolled piece channel communicating with the first rolled piece channel.
[0016] The mounting seat 1 is provided with an air inlet 5 communicating with the air jet orifice 2. The air inlet 5 is connected to the air source through an intake pipeline. The intake pipeline is a metal hose, and the air source is compressed air.
[0017] The number of the air jet orifices 2 can be set according to actual needs. A connecting plate 3-2 is further provided on the outer wall of the gland 3. The connecting plate 3-2 is welded and fixed to the mounting seat 1 to strengthen the connection strength between the gland 3 and the mounting seat 1.
[0018] As Figure 2As shown in the figure, the utility model is arranged between the pinch roll 6 and the diameter gauge 7. Among them, the gland 3 is located on the side close to the pinch roll 6, and the double-sided guide groove 4 is located on the side close to the diameter gauge 7. The rolling direction of the rolled piece is as shown by the arrow. When the rolled piece comes out of the pinch roll 6, the air source is conveyed from the intake pipe to the air inlet 5 and ejected from the air jet 2. Under the guidance of the annular guiding part 3-1 of the gland 3, the air flow blows the surface of the rolled piece in the direction opposite to the rolling direction, removing the cooling water attached to the surface of the rolled piece, preventing the cooling water from being brought to the diameter gauge 7, enabling the diameter gauge 7 to maintain long-term stable and accurate detection, strengthening the control accuracy of the product size, and improving the product quality.
[0019] Based on the original double-sided guide groove, the utility model can remove a part of the double-sided guide groove for installing this air blowing device, which does not affect the layout of other equipment and the normal operation of the rolled piece. While solving the problems existing in the prior art, it effectively controls the cost of equipment transformation.
