[0022]The cable entry of the present invention will be described in detail below with reference to the drawings, such asFigure 1-3As shown, a heat-treating device for elastic titanium-nickel alloy temple wire-shaped blanks. The heat-treating device includes a heat-resistant glass tube 11, a high-frequency coil 12, and a protective gas introduction device 13, and the heat-resistant glass tube 11 is vertical. The high-frequency coil 12 is wound on the outer peripheral surface of the heat-resistant glass tube 11, and the protective gas introduction device is arranged straight and is provided with a through hole 112 along the axial direction. The through hole 112 includes a feed port 113 and a discharge port 114. 13 communicates with the through hole 112.

[0023]The protective gas introduction device 13 is arranged on the side of the discharge port 114 of the heat-resistant glass tube 11 and is sleeved on the outer periphery of the heat-resistant glass tube 11, and includes an interface 14 that is butt-connected with the gas source pipe of the protective gas. It communicates with an air hole provided on the wall of the heat-resistant glass tube 11.

[0024]A further arrangement of the present invention: the protective gas introduction device 13 is sleeved on the outer circumference of the heat-resistant glass tube 11, and a heat-resistant layer 17 is provided between the protective gas introduction device 13 and the outer wall of the heat-resistant glass tube 11.

[0025]The inlet 113 of the heat-resistant glass tube 11 is provided with a protective gas choke device 16, and the protective gas choke device 16 prevents the protective gas from flowing out of the inlet 113.

[0026]The discharge port 114 of the heat-resistant glass tube 11 is provided with a protective gas blocking device 16, and the protective gas blocking device 16 prevents the protective gas from flowing out of the discharge port 114.

[0027]Both the inlet 113 and the outlet 114 are provided with a protective gas choke device 16, and the protective gas choke device 16 blocks the inlet 113 and the outlet 114.

[0028]The protective gas blocking device 16 is sleeved on the outer circumference of the heat-resistant glass tube 11, and a heat-resistant layer 17 is provided between the protective gas blocking device 16 and the outer wall of the heat-resistant glass tube 11.

[0029]The protective gas flow blocking device 16 includes a blocking surface that blocks the nozzle of the heat-resistant glass tube 11, and the blocking surface is composed of at least 3 movably expandable fan-shaped pieces 19.

[0030]The fan-shaped piece 19 is made of elastic carbon fiber.

[0031]In the heat treatment device for the elastic titanium-nickel alloy eyeglass leg wire blanks of the present invention described above, the heat-resistant glass tube 11 is erected, and the treated wire blanks enter from the inlet 113, according to the preset heating temperature and After the heating time is heated, the free-falling body comes out from the discharge port 114, the linear blank is heated therein and does not touch the wall of the heat-resistant glass tube 11 during heat preservation, which improves the contact surface between the linear blank and the heating and heat preservation cavity And produce the bad situation of uneven heating.

[0032]The protective gas flow blocking device 16 is provided at the feed port 113 and the discharge port 114 of the heat-resistant glass tube 11, so that the protective gas can be held in the heat-resistant glass tube 11 excellently, so that the elastic titanium-nickel alloy temple line The heat treatment effect of the profile billet is better. In the blocking surface provided by the gas flow blocking device, the fan-shaped sheet 19 uses its own elastic fiber material characteristics to open and recover. When the processed linear blank material contacts the fan-shaped sheet 19, it is squeezed by it. The fan-shaped piece 19 is opened for the linear blank material to enter or exit, and then the fan-shaped piece 19 recovers by itself to block the outflow of gas.

[0033]The high-frequency coil 12 is wound around the heat-resistant glass tube 11 to heat it so that the ambient temperature in the through hole 112 as the path for the linear blank material to pass through meets the heat treatment requirements.
