Description

Technical Field

[0001] The utility model relates to the technical field of rolling equipment, and particularly relates to a novel water-cooled guide groove device before a flying shear. Background Art

[0002] In the production process of ribbed steel or wire rods, there are situations where the head and tail of the steel material crack due to rolling, the head and tail steel structures are uneven, and the head and tail dimensions deviate greatly. Usually, a certain distance of the head and tail is sheared by a flying shear. The flying shear cutting usually triggers the flying shear to execute the head and tail cutting commands by logical judgments such as the speed of the steel material and thermal detection.

[0003] In the actual production process, the high temperature of the steel material causes the temperature of the guide groove before shearing to be too high, and the radiant heat is serious, which easily makes the thermal detection abnormal. If spray water is added to cool the guide groove, it will cause a large amount of fog at the thermal detection point and the spray water will block the detection. All of the above problems can cause abnormal thermal detection signals. If the head and tail are not sheared, it is easy to cause problems such as steel jamming and steel flying, which pose great safety hazards, increase the maintenance cost and production cost, and lead to low production efficiency. Therefore, the above problems need to be solved urgently. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a novel water-cooled guide groove device before a flying shear, which avoids the problems of large fog and shielding caused by spraying, can reduce the temperature of the guide groove before shearing, facilitates the thermal detection of steel materials and the head and tail shearing work, and improves production safety.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions:

[0006] A novel water-cooled guide groove device before a flying shear includes a guide groove body, a flying shear, and a thermal detection device. The guide groove body guides the steel material into the flying shear. The thermal detection device is located on one side or the upper side of the guide groove body. After detecting that the steel material enters the guide groove body, it starts the flying shear according to the material speed and shears the head and / or tail of the steel material. One side or both sides of the head end of the guide groove body are provided with a guide groove cooling water tank, and the guide groove cooling water tank is provided with a cooling water inlet pipe and a cooling water outlet pipe to control the inflow and outflow of cooling water.

[0007] By adopting the above technical solution, a cooling water tank is added to the side of the guide groove body, which can reduce the heat of the guide groove body at the thermal detection point and effectively avoid the abnormal situation of the thermal detection signal caused by the overheating of the guide groove. The cooling water tank can control the cooling water circulation through the cooling water inlet pipe and the cooling water outlet pipe. While improving the cooling effect, it ensures that the amount of water inside the guide groove cooling water tank is sufficient and does not overflow into the guide groove body groove, effectively avoiding the influence of water vapor on the signal.

[0008] Furthermore, the central position of the guide groove cooling water tank is arranged close to the detection position of the thermal detection device.

[0009] By adopting the above technical solution, it is further convenient to reduce the heat of the guide groove body at the heat detection position, and avoid abnormal conditions caused by overheating of the guide groove for the heat detection signal.

[0010] Furthermore, a cooling water inlet regulating valve is connected in the cooling water inlet pipe.

[0011] By adopting the above technical solution, the inlet speed of the cooling water is controlled to ensure that there is sufficient water volume inside the guide groove cooling water tank.

[0012] Furthermore, a cooling water outlet regulating valve is connected in the cooling water outlet pipe.

[0013] By adopting the above technical solution, the drainage speed of the cooling water is controlled to ensure that the water volume inside the guide groove cooling water tank does not overflow, and avoid water vapor affecting the signal.

[0014] Furthermore, a guide groove cover plate is provided above the guide groove body.

[0015] By adopting the above technical solution, the guide groove cover plate is covered above the guide groove body, and the limiting steel material warps upward.

[0016] Furthermore, the guide groove cover plate is movably connected above the guide groove body.

[0017] By adopting the above technical solution, it is convenient to open the upper side of the guide groove body, realize the maintenance and detection work inside the guide groove, and facilitate cleaning and other work.

[0018] Furthermore, a plurality of cover plate anti - detachment devices are provided on the guide groove body to prevent the guide groove cover plate from falling off the guide groove body.

[0019] By adopting the above technical solution, it is prevented that the guide groove cover plate is detached from the guide groove body.

[0020] Furthermore, there are at least four cover plate anti - detachment devices, including a top pressure plate. A pressing block is connected to the guide groove cover plate. One end of the top pressure plate close to the flying shear is connected downward to the guide groove body, and the other end abuts against the upper side of the pressing block.

[0021] By adopting the above technical solution, the top pressure plate presses the guide groove cover plate above the guide groove body through the pressing block. In the steel - passing direction, the pressing block is brought to the connection position of the top pressure plate and the guide groove body, making its moving and opening direction opposite to the steel - passing direction. While preventing the guide groove cover plate from detaching, it is convenient for the active opening of the guide groove cover plate.

[0022] Furthermore, the lower side of the top pressure plate is set as an inclined plane, and the inclined direction is upwardly inclined away from the flying shear side, and the top surface of the pressing block is set as a corresponding inclined plane.

[0023] By adopting the above technical solution, it is convenient for the pressing block to enter from the outside of the top pressure plate, so that the pressing block and the top pressure plate are better in upper and lower abutment.

[0024] Furthermore, the guide groove cooling water tank is composed of welded steel plates.
