Detailed Description
The following detailed description of the present invention is provided in connection with the accompanying drawings and the embodiments, and is not intended to limit the scope of the invention.
As shown in fig. 1 and 2, the device for quickly mounting and dismounting the hammer rod of the embodiment includes a support 1, an induction coil 2 and a medium frequency power supply 3, wherein the induction coil 2 is disposed above the support 1, the induction coil 2 is electrically connected with the medium frequency power supply 3, a blanking hole 4 is disposed in the middle of the upper surface of the support 1, the induction coil 2 is provided with a casing 5 which completely covers the induction coil 2, a cylindrical heating culvert 6 which is through from top to bottom is disposed in the middle of the casing 5, the heating culvert 6 is coaxial with the induction coil 2, and the blanking hole 4 is coaxial with the heating culvert 6. The housing 5 may or may not be fixed to the support 1, and the induction coil 2 is a vertical coil, which may be a set of spirally wound circular coils, and when it is coupled to the 500KW medium frequency power supply 3, it may heat the piston to 650 ℃ in 30 minutes.
The utility model utilizes the heating principle of the medium-frequency induction coil, namely when the medium-frequency alternating current is introduced into the induction coil, an alternating magnetic field can be generated, and further induced current with the same frequency is generated in a workpiece in the middle of the induction coil, and the induced current is non-uniform in distribution of the workpiece, strong in surface, weak in the inner part and close to 0 in the center part; in this way, when the piston with the broken shank is placed in the heating channel 6, the piston is heated, while the broken shank is not.
The shell 5 and the induction coil 2 are isolated by insulation, and the shell 5 isolates the induction coil 2 to prevent radiation, electric shock and other injuries; the gap between the hole wall of the heating culvert 6 and the induction coil 2 is 2-3mm, and the diameter of the heating culvert 6 is larger than the outer diameter of the piston so as to be convenient for placing the piston.
The blanking hole 4 is circular, the diameter of the blanking hole 4 is smaller than that of the heating culvert 6, and the diameter of the blanking hole 4 is larger than that of the hammer rod. When the piston is put into the heating culvert 6, the upper surface of the support 1 can play a supporting role, and the broken hammer rod which is taken down can fall from the blanking hole 4.
The hole wall of the heating culvert 6 is made of a high-temperature-resistant non-magnetic material, so that induction current can be prevented from being generated on the hole wall of the heating culvert 6, and meanwhile, the hole wall of the heating culvert 6 is prevented from being melted and deformed at high temperature.
When the device is used, a piston with a broken hammer rod is flatly placed in the heating culvert 6, a power supply is connected, the piston is heated by the induction coil 2 to be expanded, even if the aperture of an inner hole of the piston is increased and the broken hammer rod is not heated, the broken hammer rod can be easily taken out after the broken hammer rod is knocked after about 12 minutes; and (3) continuing heating the piston, detecting the temperature of the piston by using an infrared thermometer, after about 30 minutes, putting a new hammer rod into the inner hole of the piston when the temperature of the piston reaches 650 ℃, turning off a power supply, and after the piston is cooled, installing the hammer rod.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
