The pot is made of stainless steel or aluminum, for example, a body 3 of the pot is made of stainless steel and matches with a plate 30 made of aluminum alloy, and a body 4 of the pot is made of aluminum and matches with a plate made 40 of stainless steel, and then the body is friction melted with the plate by using a friction melting machine 5 to form a finished pot 6.
Fig. 5 is a plan view showing the operation of the friction melting machine 5, wherein a fixing seat 51 is used to draw the body 3 or 4 by using a vacuum suction so that the body 3 or 4 is fixed without rotation, and then two grippers 520 of a rotating holder 52 clamp a heating device 30 or 40 as shown in Fig. 6. When the body 3 or 4 is drawn by the vacuum suction, it is secured on the fixing seat 51, and the heating device 30 or 40 is clamped by the two grippers 520 so that a bottom end of the heating device 30 or 40 extends outward at a certain distance, and the rotating holder 52 is rotated and pushed laterally to contact with the body 3 or 4, then the rotating holder 52 keeps rotation to rub with the bottom end of the body 3 or 4, generating a high heat. When using the heating device made of aluminum alloy, an peripheral side of the body 3 is hot-melted because of a high temperature, but the bottom end of the body 3 does not reach a melting point, a surface of the bottom end of the body 3 is soften slightly and has a pore expansion so that a melted heating device 30 penetrates into pores expanding on the surface of the bottom end of the body 3, thereafter a spindle retains the melted heating device 30 to move laterally so to press the bottom end of the body 3 so that the heating device 30 is melt-connected with the body 3, forming an integrally formed pot (as illustrated in Fig. 7) without loose.
When the heating device 40 is made of a stainless steel plate, it cooperates with the body 4 made of aluminum, so a high temperature generates from a rotary friction of the body 4 and the heating device 40, and the bottom end of the body 4 is hot-melted because of the high temperature, but the heating device 40 does not reach a melting point, a surface of the bottom end of the body 4 is soften slightly and has a pore expansion, and a spindle retains the heating device 40 to move laterally, the bottom end of the body 4 penetrates into pores expanding on the heating device 40 so that the heating device 40 is melt-connected with the body 4.
By using such a friction and melt-connection, the body 3 or 4 and the heating device 30 or 40 are not degreased in a wash oil process, and the heating device 30 or 40 casts the electric pipe in the channel of the heating device, the finished product is obtained by polishing after a friction melting. The electric pipe of the heating device 30 or 40 is forged, and the body 3 or 4 is friction melted and polished, the electric pipe is retained.
