Description

Technical Field

[0001] The utility model relates to the technical field of continuous casting billet processing, in particular to a continuous casting billet cutting device and continuous casting billet cutting equipment. Background Art

[0002] Cutting continuous casting billets is one of the necessary means in the processing of continuous casting billets. The principle is to heat the continuous casting billets to the combustion temperature through the combustion of natural gas and oxygen, and then use high-pressure oxygen to make the billets burn on the oxygen wind line and blow away the combustion products (ferroferric oxide) by the high-pressure oxygen wind line to form a slit. In the actual production process, the cutting of continuous casting billets can be achieved by a manual hand-held cutting gun. For example, when it is necessary to take a low-magnification sample, the operating cost of starting the automatic equipment to cut the continuous casting billet is high and the operation is inconvenient. At this time, it is more convenient to use a manual hand-held cutting gun for cutting. However, when the manual hand-held cutting gun is used to cut the continuous casting billet, the reaction force of the high-pressure oxygen causes the hand-held cutting gun to swing greatly, and the wind line of the cutting continuous casting billet will swing, resulting in uneven slits and uneven cross-sections when the continuous casting billet is cut.

[0003] Therefore, it is urgent to propose a continuous casting billet cutting device and a continuous casting billet cutting equipment to solve the above technical problems. Utility Model Content

[0031] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar components or components having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0032] In the description of the present invention, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection, a mechanical connection or an electrical connection, a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] In the description of the present utility model, unless otherwise clearly stipulated and limited, a first feature being “above” or “below” a second feature may include the first feature and the second feature being directly in contact, or may include the first feature and the second feature not being in direct contact but being in contact through another feature between them.

[0035] like Figure 1 to Figure 4 As shown, the continuous casting billet cutting device provided in the embodiment of the present application includes a gas source device and a continuous casting billet cutting device, the continuous casting billet cutting device includes a support stand 1, a swing arm 2 and a cutting air gun 3, and the output end of the gas source device is connected to the cutting air gun to deliver high-pressure gas used for cutting the continuous casting billet to the cutting air gun. Exemplarily, the gas source device can be an oxygen cylinder, and the oxygen cylinder delivers high-pressure oxygen to the cutting air gun. Of course, other gases such as acetylene can also be used when cutting the continuous casting billet, which is not specifically limited here.

[0036] The bottom of the support stand 1 is arranged on the bearing surface of the continuous casting billet, and the support stand 1 has a receiving space 11 for the continuous casting billet to extend into, and specifically, the bearing surface can be the ground or a work surface. One end of the swing arm 2 is rotatably connected to the top of the support stand 1, and the other end of the swing arm 2 extends from the top of the support stand 1 to a side close to the continuous casting billet; the cutting air gun 3 is fixedly connected to one end of the swing arm 2 close to the continuous casting billet, and the cutting air gun 3 is configured to swing synchronously with the swing arm 2 and cut the continuous casting billet.

[0037] In the specific implementation, first place the support stand 1 on the bearing surface bearing the continuous casting billet, and make the continuous casting billet partly located inside the accommodating space 11, so that the support stand 1 can maintain a relatively stable state on the bearing surface, and fix the cutting air gun 3 to the swing arm 2 to complete the preparation work. When starting to cut the continuous casting billet, pull the swing arm 2 to one side of the continuous casting billet, and the cutting air gun 3 also moves to one side of the continuous casting billet with the swing arm 2, and then push the swing arm 2 forward at a uniform speed until the cutting air gun 3 moves to the other side of the continuous casting billet. Because when the swing arm 2 swings, it takes the rotating connection part between the swing arm 2 and the top of the support stand 1 as the origin, and swings with the length of the swing arm 2 itself as the radius, which is similar to the principle of a pendulum. Therefore, the moving trajectory of the cutting air gun 3 on the swing arm 2 is an arc line. Furthermore, the cutting line finally formed by the cutting air gun 3 on the continuous casting billet will be a straight line.

[0038] The continuous casting billet cutting device and the continuous casting billet cutting equipment provided in the embodiment of the present application are provided with a rocker arm 2, and the swing of the rocker arm 2 can drive the cutting air gun 3 to swing synchronously, so that the cutting line formed by the cutting air gun 3 on the continuous casting billet is always a straight line, which is beneficial to improve the flatness of the cutting seam, improve the cutting speed and cutting effect; and the rocker arm 2 is rotatably connected to the supporting frame 1, and the supporting frame 1 can be relatively fixed on the bearing surface. In this way, there is no need to manually hold the cutting air gun 3 to cut the continuous casting billet, which can reduce the labor intensity while ensuring the cutting effect.

[0039] Specifically, the support frame 1 includes a plurality of vertical poles 12 arranged at intervals, the tops of the plurality of vertical poles 12 are sequentially connected by a plurality of connecting cross bars 13, and the plurality of vertical poles 12 enclose a receiving space 11. With such an arrangement, the support frame 1 has a simple structure, is not only convenient and quick to manufacture, but also convenient to move, thereby improving the convenience in application.

[0040] Preferably, if Figure 1 As shown, the number of the vertical poles 12 and the connecting cross bars 13 are both set to four, and the supporting frame 1 is a rectangular parallelepiped frame, for example, a rectangular parallelepiped frame with a length of 70 cm, a width of 50 cm, and a height of 110 cm.

[0041] Furthermore, a reinforcing rod 14 is fixedly connected between two adjacent upright poles 12. The reinforcing rod 14 is provided to increase the overall strength of the supporting frame 1, thereby improving the stability of the supporting frame 1.

[0042] like Figure 1 and Figure 2 As shown, in some embodiments, the swing rod 2 includes a first rod 21 and a second rod 22, the first rod 21 and the second rod 22 are in a T-shape, the first rod 21 is rotatably connected to the top of the support frame 1, and the first rod 21 swings around its own axis, one end of the second rod 22 is fixedly connected to the first rod 21, and the other end of the second rod 22 extends from the first rod 21 to one side of the continuous casting billet. That is: the cutting air gun 3 is fixed to one end of the second rod 22 close to the continuous casting billet.

[0043] One end of the second rod 22 may be welded to the first rod 21 .

[0044] By setting the rocker arm 2 as a T-shaped rocker arm, compared with a single-rod rocker arm, the lateral supporting capacity can be enhanced, that is, the supporting capacity along the extension direction of the first rod 21 can be enhanced, preventing the rocker arm 2 from moving along the extension direction of the first rod 21, which is beneficial to improving the stability of the rocker arm 2 during operation.

[0045] Preferably, if Figure 1 As shown, the two ends of the first rod 21 are respectively rotatably connected to two opposite connecting cross bars 13. Such an arrangement can make the force on the first rod 21 more balanced during the rotation process.

[0046] Furthermore, a bearing 4 is fixedly disposed on each of the two opposite connecting cross bars 13, and both ends of the first rod 21 are rotatably connected to the corresponding bearings 4. Specifically, the two bearings 4 can be welded to the two opposite connecting cross bars 13. The bearings 4 are disposed to reduce the rotational friction when the first rod 21 rotates, so that the rotation is more stable and smooth.

[0047] Specifically, a driving motor connected to the first rod 21 may be provided, and the rotation angle of the first rod 21 may be accurately controlled by the driving motor, thereby controlling the overall swing angle of the swing rod 2 .

[0048] Preferably, the two bearings 4 are symmetrically arranged, so that the first rod 21 rotatably connected between the two bearings 4 is basically parallel to the other two connecting cross bars 13. In this way, it can effectively ensure that the second rod 22 will not produce friction and collision with the vertical rod 12 during the swinging process of the swing rod 2.

[0049] like Figure 1 to Figure 4 As shown, in some embodiments, a bracket 5 is fixedly provided at one end of the swing arm 2 close to the continuous casting billet, and the bracket 5 is used to carry the cutting air gun 3. Specifically, the cutting air gun 3 is fixedly connected to the bracket 5, and illustratively, the cutting air gun 3 can be fixed to the bracket 5 by bolt connection, clamping connection, bonding, etc., which can be determined according to actual conditions.

[0050] With such an arrangement, the bracket 5 can stably carry the cutting air gun 3, and can prevent the cutting air gun 3 from moving or shaking during operation, which is beneficial to improving the stability of the cutting air gun 3 and further ensuring the flatness of the cut seam on the continuous casting billet.

[0051] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
