Description
Technical Field
[0001] The utility model relates to the technical field of steel discharging machines, in particular to a heating steel discharging machine for a rolling mill with a protection mechanism. Background Art
[0002] After being heat-treated by a heating furnace in a rolling mill, the rolled steel will be output and transferred away by a steel discharging machine, and the rolled steel will be moved to the next process for processing. However, there are still deficiencies in the use of the heating steel discharging machine in the related technology. There is no structure for protecting the rotating rollers in the steel discharging machine. After the rolled steel comes out of the heating furnace, it has a relatively high temperature. If the rotating rollers convey the rolled steel at a relatively high temperature for a long time, it is easy to cause damage to the rotating rollers. Moreover, there is no protective cover, and there is a situation where people may accidentally touch the just-out rolled steel and get scalded. Therefore, we propose a heating steel discharging machine for a rolling mill with a protection mechanism to solve the above problems. Content of the Utility Model
[0003] The purpose of the utility model is to solve the above-mentioned drawbacks, and a heating steel discharging machine for a rolling mill with a protection mechanism is proposed.
[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0005] A heating steel discharging machine for a rolling mill with a protection mechanism includes a protective cover of the heating steel discharging machine for a rolling mill. An out-steel mechanism is arranged on the protective cover, an air-cooling mechanism is arranged on the protective cover, a water tank and a sealing cover are fixedly connected to the front side of the protective cover, and a spray cooling mechanism is arranged between the protective cover, the water tank and the sealing cover. The spray cooling mechanism includes a spray cooling component and a reciprocating swing component.
[0006] Specifically, the out-steel mechanism includes two lower rotating rollers rotatably connected to the inner walls of the front and rear sides of the protective cover, and a hydraulic cylinder fixedly connected to the top of the protective cover. An installation frame is fixedly connected to the output shaft of the hydraulic cylinder, a driving motor is fixedly connected to the front side of the installation frame, and an upper rotating roller is fixedly connected to the output shaft of the driving motor.
[0007] Specifically, conveying grooves are formed on the outer sides of the upper rotating roller and the lower rotating roller.
[0008] Specifically, the air-cooling mechanism includes a blower fixedly connected to the top of the protective cover. The air outlet end of the blower is fixedly communicated with an air outlet pipe, and a plurality of air blowing heads are fixedly communicated with the bottom of the air outlet pipe.
[0009] Specifically, the air outlet pipe is fixedly connected to the inner wall of the top of the protective cover.
[0010] Specifically, the spray cooling assembly includes a booster pump fixedly connected to the top of the sealing cover, and a plurality of hollow tubes rotatably connected to the inner walls of the front and rear sides of the protective cover. The front ends of the plurality of hollow tubes are all communicated with the sealing cover. The top of the booster pump is communicated with the bottom of the water tank, and a plurality of spray heads are fixedly communicated with the plurality of hollow tubes.
[0011] Specifically, the reciprocating swing assembly includes a support plate fixedly connected to the rear side of the protective cover, and an external gear ring fixedly sleeved on the outer side of the hollow tube. One side of the support plate is fixedly connected with a cylinder, and a moving plate is fixedly connected to the output shaft of the cylinder. Two racks are fixedly connected to one side of the moving plate, and the two racks are respectively engaged with the corresponding external gear rings.
[0012] Specifically, four connecting plates are fixedly connected to the rear side of the protective cover. The same guide rod is fixedly connected between two connecting plates located on the same horizontal plane. A slider is slidably sleeved on the outer side of the guide rod, and the two sliders are respectively fixedly connected to the corresponding racks.
[0013] In the present utility model, for a steel heating and discharging machine with a protection mechanism in a rolling mill, the device is moved to the position of the discharge port of the heating furnace, and the discharge port is close to the side of the spray head. When the rolled steel after heat treatment extends out of the discharge port of the heating furnace and moves into the protective cover, through the setting of the protective cover, it can play a protective role and avoid the situation of accidental contact with the rolled steel and causing scalding. By starting the blower, booster pump and forward and reverse start cylinder, through the blower, the blowing air can be blown into the air outlet pipe and finally blown out from a plurality of blowing heads, so as to air-cool the rolled steel. At the same time, through the booster pump, the water pressure in the water tank can be pumped into the sealing cover, then into a plurality of hollow tubes, and finally water mist is sprayed out from a plurality of spray heads to spray and cool the rolled steel up and down, making the cooling more uniform and comprehensive, with better cooling effect and higher efficiency.
[0014] In the present utility model, for a steel heating and discharging machine with a protection mechanism in a rolling mill, through the forward and reverse start cylinder, it will drive the left and right reciprocating movement of the moving plate and the two racks. The two racks drive the forward and reverse rotation of a plurality of external gear rings and hollow tubes, and the plurality of hollow tubes drive the left and right reciprocating swing of a plurality of spray heads, so as to swing and spray-cool the rolled steel, further improving the cooling effect and efficiency, avoiding damage to the upper and lower rotating rollers caused by too high temperature of the rolled steel, greatly increasing the service life of the upper and lower rotating rollers. When the left end of the rolled steel moves to the top of the two lower rotating rollers, it can play the role of supporting the rolled steel. When the rolled steel is completely removed from the heating furnace, start the hydraulic cylinder, and the hydraulic cylinder drives the mounting frame and the upper rotating roller to move down, so that the rolled steel abuts between the upper and lower rotating rollers. Then start the driving motor, and the driving motor drives the rotation of the upper rotating roller. With the assistance of the two lower rotating rollers, the rolled steel can be conveyed to the next process to the left.
[0015] The structure of the utility model is reasonably designed. Through the setting of the protective cover, it can play a protective role to avoid accidental contact with the rolled steel and cause scalding. Under the dual cooling of air cooling and spray cooling, the rolled steel can be quickly cooled down to avoid damage to the upper and lower rotating rollers due to excessive temperature of the rolled steel, making the protection effect on the upper and lower rotating rollers better and greatly improving the service life of the upper and lower rotating rollers.
