Description

Technical Field

[0001] The utility model relates to the field of hot rolling devices, in particular to an anti-interference cooling device for the roller path guide groove of a hot shear instrument. Background Art

[0002] The hot shear instrument is an important device for the production of bars in a rolling mill. During the continuous rolling process of the hot shear instrument, the temperature of the roller path guide groove at the irradiation position of the hot shear instrument will rise due to long-term baking by red-hot steel. On the one hand, due to the influence of high temperature, the roller path guide groove has a risk of cracking. On the other hand, because the hot shear instrument has high sensitivity, it will be interfered by the external on-site high-temperature conditions, resulting in the out-of-control of the interference signal of the hot shear instrument, the unevenness of the rolling multiple lengths, the decrease of the multiple rate, and the disorder of the rolling multiple lengths. Therefore, there is an urgent need for a cooling device for the roller path guide groove of the hot shear instrument with strong adaptability and convenient production. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide an anti-interference cooling device for the roller path guide groove of a hot shear instrument, which can effectively cool the roller path guide groove at the irradiation position of the hot shear instrument continuously and efficiently.

[0004] To solve the above technical problem, the technical solution adopted by the utility model is: an anti-interference cooling device for the roller path guide groove of a hot shear instrument, including a plurality of groups of cooling box fixing plates arranged relatively left and right on the side of the roller path close to the hot shear instrument. Each cooling box fixing plate includes a base arranged on the side surface of the roller path. At the upper edge of the base, a hinge shaft is provided, and a baffle plate adapted to the width of the base and with a length exceeding the length of the base is hinged through the hinge shaft. A rotating stopper for limiting the baffle plate is arranged on the base. A horizontal bearing plate is arranged at the bottom outside the roller path. Above the horizontal bearing plate, a cooling water tank is arranged between each group of cooling box fixing plates. The first cooling water tank on the side of the roller path close to the hot shear instrument is connected to the cooling water pipe of a DC motor for water inlet. A cooling water transfer pipeline is connected between the cooling water tanks, and a water outlet pipe is arranged at the bottom of the last cooling water tank.

[0005] A further improvement of the technical solution of the utility model lies in that: a groove for bearing the baffle plate is arranged in the middle of the base of the cooling box fixing plate. The width of the baffle plate is smaller than the width of the groove. A rotating through hole through which the rotating stopper can pass is arranged through the baffle plate. The rotating stopper is connected to the groove of the base through a screw.

[0006] A further improvement of the technical solution of the utility model lies in that: a fixing through hole is arranged at the end of the baffle plate extending out of the groove, and a threaded hole opposite to the position of the fixing through hole is arranged on the cooling water tank.

[0007] A further improvement of the technical solution of the present utility model lies in that: a return water tank is fixedly arranged on the side of the roller path far from the hot shear instrument, and a water outlet pipe arranged on the last cooling water tank on the side of the roller path close to the hot shear instrument passes under the roller path and is connected into the return water tank, and a drain pipe for discharging water is arranged on the return water tank.

[0008] A further improvement of the technical solution of the present utility model lies in that: the cooling water transmission pipe is a rubber hose, and the drain pipe is a galvanized iron pipe.

[0009] A further improvement of the technical solution of the present utility model lies in that: a switch valve is arranged on the cooling water pipe of the DC motor, and a switch valve is arranged on the return water tank.

[0010] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model is as follows: by arranging a bearing plate and a fixing plate on the outer side of the roller path guide groove, a plurality of cooling water tanks can be detachably arranged on the side of the roller path close to the hot shear instrument, which is more flexible and free. By arranging structures such as a base and a baffle, it is not only firmly fixed, but also convenient for disassembly operation. By circulating water in the cooling water tank, the roller path can be effectively cooled by using the cooling water. By connecting the cooling water tank to the cooling water pipe of the DC motor and using the cooling water of the DC motor as the water source, not only the temperature of the water is low enough and no additional cooling water source needs to be set, but also the pressure of the cooling water of the DC motor is sufficient, and no additional pressure pump needs to be set for leading to a plurality of cooling water tanks. By arranging a return box on the other side of the roller path, the flow time of the cooling water in the cooling device can be effectively extended, and the utilization degree of the cooling water can be improved.

[0016] The present invention is further described in detail below in conjunction with the embodiments:

[0017] Embodiment 1

[0018] like Figure 1 , Figure 2 The figure shows a schematic diagram of the structure of a heat shearing instrument roller guide groove anti-interference cooling device, where a plurality of groups of cooling box fixing plates 3 arranged opposite to each other are arranged on the outer side of the roller 1 close to the heat shearing instrument, and a horizontal support plate 2 is arranged on the bottom side. A cooling water tank 4 is arranged between each group of cooling box fixing plates 3 on the horizontal support plate 2. In this embodiment, the number of cooling water tanks 4 is 2, and the number of cooling box fixing plates 3 is 4.

[0019] Each cooling box fixing plate 3 has a structure as follows Figure 3 As shown, it includes a base 33 welded and fixed on the side of the roller, a groove for carrying a baffle 32 is provided in the middle of the base 33, a hinge shaft 31 is provided at the upper edge of the base 33, and a baffle 32 whose width matches the groove width of the base 33 and whose length exceeds the width is hingedly provided through the hinge shaft 31. The baffle 32 can be completely fitted in the groove, and the tail end of the baffle 32 that exceeds the groove leaks out to block the cooling water tank 4. A long strip-shaped rotating through hole 35 is provided on the baffle plate 32 at a position above the groove, and a rotating stopper 34 is provided on the groove of the base 33 through a screw connection. The rotating stopper 34 is also in the shape of a long strip and is smaller than the rotating through hole 35. When the rotating direction of the rotating stopper 34 is a vertical bar, when the baffle plate 32 is adjusted to return to the groove, the rotating stopper 34 can smoothly pass through the rotating through hole 35. At this time, the rotating stopper 34 can be rotated to a horizontal bar, and the rotating stopper 34 is perpendicular to the direction of the rotating through hole 35, and is smoothly stuck to limit the baffle plate 32, so as to complete the fixation of the cooling water tank 4. A fixing through hole 36 is provided on the tail end of the baffle 32 extending out of the groove, and a threaded hole corresponding to the position of the fixing through hole 36 is provided on the cooling water tank 4. When the position of the cooling water tank 4 is set, the baffle 32 returns to the groove, and after the tail end of the extended baffle 32 fixes the cooling water tank 4, bolts are used to pass through the fixing through hole 36 and screwed into the threaded hole of the cooling water tank 4 at the same time, so as to realize the positioning and re-fixation of the cooling water tank 4, and the fixation is more stable and reliable.

[0020] The two cooling water tanks 4 are connected and communicated through a cooling water transfer pipeline 9. The first cooling water tank is connected to the cooling water pipe 5 of the DC motor. A switching valve is provided on the cooling water pipe 5. By opening the valve, the cooling water of the DC motor can be put into the cooling water tank 4, and then all the cooling water tanks 4 can be filled. The cooling water pipe of the DC motor is not only a ready-made water source, but also has a low enough water temperature and sufficient pressure, and all the cooling water tanks 4 can be filled without a booster pump. An outlet pipe 6 is provided at the upper bottom of the last cooling water tank. The cooling water enters from the first cooling water tank and exits from the last cooling water tank, thereby realizing continuous cooling of the roller table.

[0021] A return water tank 7 with a built-in switching valve is fixedly provided on one side of the roller table 1 away from the hot shear. The outlet pipe 6 passes under the roller table and is connected to the return water tank 7, so that the cooling water can flow into the return water tank 7 for long-term retention, thereby prolonging the flow time of the cooling water in the cooling device and improving the utilization degree. A drain pipe 8 for final water discharge is connected to the return water tank 7. The cooling water transfer pipeline 9 is a rubber hose, and the drain pipe 8 is a galvanized iron pipe, so as to better pass under the roller table and will not deform and shake due to the flow of water. This new type can reduce the temperature of the roller table groove by continuously introducing cooling water, so that the temperature drop of the roller table groove does not reach the temperature that affects the hot shear signal, enabling the hot shear to operate normally, meeting the requirements of the production process, ensuring the rolling multiple length, and improving the sizing rate.

[0022] The embodiments described above are only used to describe the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
