Description

Technical Field

[0001] The utility model relates to the field of pipe processing, in particular to a high-frequency heating device for pipes. Background Art

[0002] At present, in order to improve the strength of steel pipes, heat treatment is generally carried out after the steel pipes are formed. The purpose of heat treatment is to improve the plasticity of steel and reduce deformation resistance. The traditional process includes heating and cooling. When heating, the pipes are generally heated in a heating furnace. After heating, physical cooling is performed. This process requires the handling of pipes, which is discontinuous and prone to safety accidents. Secondly, this operation method is prone to uneven local cooling, which cannot suppress the coarsening of grains and easily generates individual coarse structures, which ultimately leads to problems such as reduced pipe strength and unqualified products. Utility Model Content

[0010] Preferably, the water inlet is connected to the corresponding circulation port through a hose.

[0011] Working principle:

[0012] The formed pipe is placed on the lifter manually, and then the controller controls the lifter to lift the pipe to the specified height. Then the controller controls the high-frequency heater to move until the first cooling tube, the thermal coil and the second cooling tube are sleeved on the pipe. Then the telescopic electric cylinders at both ends are extended so that the connecting sleeves cover the two ends of the pipe. Then the controller sends a command to make the thermal coil heat up rapidly. In the process of moving to the right, the nozzle on the first cooling tube does not work. As the high-frequency heater moves, the pipe is heated, and the nozzle on the second cooling tube behind cools the pipe. After reaching the leftmost end, the pipe is replaced, and then the previous operation is repeated. However, when cooling after the replacement, the nozzle on the first cooling tube starts to work, and the nozzle on the second cooling tube does not work.

During cooling, the spray intensity and moving speed of each nozzle are constant, and the grains will not be coarsened due to cooling. The cooling mechanism is suitable for reciprocating operation and has strong adaptability, which greatly improves the operation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The operating platform 1 is provided with a support frame 2, and the high-frequency heating mechanism 3 is movably installed on the support frame 2. The controller 4 is provided on the upper part of the high-frequency heating mechanism 3, and the monitor 5 is provided at the front end of the controller 4. The high-frequency heating mechanism 3 is also provided with a cooling mechanism 6. The operating platform 1 is also provided with a plurality of lifters 7. Clamping mechanisms 8 are respectively provided at both ends of the support frame 2, and the clamping mechanisms 8 are mainly used to fix the pipes to be processed.

[0024] A drainage groove 9 is provided on the operating platform 2, and the drainage groove 9 is connected to a recovery pipe 10, and the recovery pipe 10 is connected to a liquid collecting tank 11. The liquid collecting tank 11 is installed on one side of the operating platform 1. Two circulation ports 12 are also provided on one side of the liquid collecting tank 11. The drainage groove 9 collects the coolant into the liquid collecting tank for recycling. Example

[0025] The difference from Example 1 is that the high-frequency heating mechanism 3 includes a high-frequency heater 30, a heat-conducting plate 31 and a heat-conducting coil 32, self-propelled wheels are respectively arranged on both sides of the upper part of the high-frequency heater 31, and the self-propelled wheels are movably assembled with the support frame 2, a heat-conducting plate 31 is arranged at the bottom of the high-frequency heater 30, and a heat-conducting coil 32 is installed at the bottom of the heat-conducting plate 31.

[0026] The cooling mechanism 6 is mounted on the high-frequency heater 30, and the cooling mechanism 6 includes a bracket 60, a first electric cylinder 61, a second electric cylinder 62, a first cooling pipe 63, a second cooling pipe 64, a nozzle 65 and a water inlet 66. The bracket 60 is installed on one side of the high-frequency heater 30, and a through hole is opened on the bracket 60. The first electric cylinder 61 and the second electric cylinder 62 are respectively fixed at the two ends of the high-frequency heater 30. The front ends of the first electric cylinder 61 and the second electric cylinder 62 are respectively provided with a first cooling pipe 63 and a second cooling pipe 64. A plurality of nozzles 65 are respectively provided on the first cooling pipe 63 and the second cooling pipe 64, and a water inlet 66 is provided on the first cooling pipe 63 and the second cooling pipe 64.

[0027] The clamping mechanism 8 includes a baffle 80, a telescopic electric cylinder 81 and a connecting sleeve 82. The baffle 80 is fixedly mounted on both ends of the support frame 2, the telescopic electric cylinder 81 is fixedly mounted on the baffle 80, and the connecting sleeve 82 is mounted on the telescopic end of the telescopic electric cylinder 81.
