Description

Automatic heating device for disassembling assembly parts {AN APPARATUS FOR HEATING THE PARTS FOR DISASSEMBLING ASSEMBLED PARTS}

The present invention relates to an automatic heating device for disassembling the assembly for heating before disassembling the custom assembled assembly by forcing the shaft and the wheel body is interlocked, in particular, heating of the assembly parts to the heating device without the manual operation of the operator The present invention relates to an automatic heating device for disassembling an assembly, which allows a more stable heating while rotating a heating part of an assembly in a seated state so that the disassembly of the assembly can be performed quickly.

In general, support trolleys and bogie wheels used in industrial sites, especially steel mills, support heavy loads such as drums and bogies. The components are assembled in a custom manner by interposing the components in a state, and the disassembly of such an assembly is illustrated in FIG. 1.

By the way, the assembly parts 100 such as the support trolley or the wheels assembled in a custom manner without key assembly are separated from the body part and the shaft part when the wear or cracking of the parts occurs. For the disassembly of the (100) first, because it is assembled in a press fit method, it is necessary to first perform the disassembly work of the assembly by heating.

That is, as schematically shown in FIG. 1, the cylinder 120 installed on the simple trolley 110 is supported by the shaft portion 102 of the assembly 100 and the fixing jig (installed on the trolley 110). The bent tip portion 106a of the 106 is fixed to the body of the assembly 100, ie the wheel portion 104, and then the worker uses the heating torch 130, the wheel 104 of the assembly 100 When the heat was applied to both sides of the part to reach the proper temperature, the cylinder 120 was advanced to disassemble the wheel 104 and the shaft portion 102 of the assembly 100.

However, at the time of disassembling such a conventional assembly part, at least two or more workers heat the assembly part 100 as a heating torch 130, so that even if the direction of the torch flame is slightly wrong, the other worker may be burned. There has been a problem that safety accidents occur frequently such as workers.

Moreover, since the worker performs the heating operation manually, the heating state of the assembly 100 is not constant, but rather, it causes heat deformation of the shaft portion 102 which can be used again, and the working time is also significantly delayed. There were various problems such as poor workability of the worker.

The present invention has been made to solve the above-mentioned conventional problems, the object of the assembly, while heating the assembly of the heating parts of the assembly parts while the heating operation of the assembly parts seated on the heating device without the manual operation of the operator to assemble more stable heating An object of the present invention is to provide an automatic heating device for disassembling an assembly, which improves workability by quickly disassembling the component.

In addition, the other object of the present invention, there is no need for the torch work of the worker when heating the parts before the disassembly work of the assembly parts, there is no fear of safety accidents, such as burns due to the misoperation during heating, more stable use It is to provide an automatic heating device for disassembling an assembly.
