[0019] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0020] In the embodiment, Figure 1-5A heat treatment processing equipment for metal products is given, comprising a lower shell 1 arranged in a semicircular shape, an air inlet cavity 2 is provided on the lower shell 1, an air duct 3 is fixedly installed on the lower shell 1, one end of the air duct 3 is communicated with the air inlet cavity 2, and the other end is communicated with the air outlet pipe of the fan 12, an upper shell 4 arranged in a semicircular shape is hinged on the lower shell 1 by a hinge, a locking assembly 5 is provided between the lower shell 1 and the upper shell 4, a reflux cavity 6 communicated with the air inlet cavity 2 is provided on the upper shell 4, an electric heating rod 7 for heating the metal pipe is provided on the lower shell 1 and the upper shell 4, an adjusting assembly 8 is provided on the lower shell 1 and the upper shell 4, which is used to adapt to metal pipes of different diameters, the metal pipe to be heat treated is placed in the lower shell 1, and then the upper shell 4 is hinged by a hinge It is closed with the lower shell 1 to form a complete annular space to accommodate the metal pipe. The locking assembly 5 is then used to firmly lock the lower shell 1 and the upper shell 4 together to ensure the sealing and stability during the heat treatment process. The fan 12 is started to introduce external air into the air inlet chamber 2 through the air duct 3. The gas then circulates through the reflux chamber 6 on the upper shell 4 to ensure that the gas around the metal pipe is evenly distributed, which helps to evenly transfer heat. At the same time, the electric heating rod 7 is activated on the lower shell 1 and the upper shell 4 to generate heat to heat the metal pipe to the required heat treatment temperature. Before the metal is preheated, the adjustment assembly 8 needs to be adjusted according to the size of the metal pipe to ensure that the metal pipe is tightly and evenly surrounded in the heating area. At the same time, the equipment can also be moved along the length of the metal pipe to increase the heating area.

[0021] Reference Figure 1-5 , wherein, the lower shell 1 and the upper shell 4 are both provided with avoidance grooves 9 which are respectively communicated with the air inlet cavity 2 and the reflux cavity 6, and the electric heating rod 7 is located in the avoidance grooves 9;

[0022] With the above-mentioned structural arrangement, when the lower shell 1 and the upper shell 4 are closed, a circular ring is formed, and the electric heating rods 7 are arranged in a circular shape and equidistantly on the inner side of the circular ring to ensure heating uniformity.

[0023] Reference Figure 1-5 The locking assembly 5 includes a protrusion 51. The lower shell 1 and the upper shell 4 are both provided with a protrusion 51 on the side away from the hinge. A plurality of screws 52 are provided on the upper protrusion 51, each of which has one end passing through and extending to the lower protrusion 51. The screws 52 are threadedly connected with locking nuts 53.

[0024] Through the above-mentioned structural setting, when the lower shell 1 and the upper shell 4 are closed, the locking nut 53 is rotated to move it downward along the screw 52 until it is tightly fitted into the surface of the lower protrusion 51. The pressure generated by the locking nut 53 presses the upper and lower protrusions tightly together, thereby achieving a firm locking of the lower shell 1 and the upper shell 4.

[0025] Reference Figure 1-5 , wherein the adjustment assembly 8 includes a connecting rod 81, two connecting rods 81 are hingedly connected to the outer side wall of the upper shell 4, and the other ends of the two connecting rods 81 are rotatably connected to the movable rod 82, and both ends of the movable rod 82 are rotatably connected to rollers 83, and the middle part of one of the connecting rods 81 is rotatably connected to a limit arm 84, and the end of the limit arm 84 away from the connecting rod 81 is rotatably connected to a slider 85, and a slide rail 86 adapted to the slider 85 is provided on the upper shell 4, and a hand screw 87 is threadedly connected to the slider 85, and one end of the hand screw 87 is in conflict with the slide rail 86;

[0026] Through the above-mentioned structural setting, by manually operating the connecting rod 81, the rollers 83 at both ends of the movable rod 82 are driven to contact the outside of the metal pipe, and the number of movable rods 82 is four, which are equidistantly distributed in a ring outside the circular ring formed by the lower shell 1 and the upper shell 4. Therefore, after the eight rollers 83 contact the outside of the metal pipe at the same time, it can not only ensure that the part of the metal pipe to be preheated is completely in the heating area, but also move along the metal pipe to further increase the preheating area.

[0027] Reference Figure 1-5 , wherein, both ends of the lower shell 1 and the upper shell 4 are provided with limit blocks 10;

[0028] Through the above-mentioned structural arrangement, the limit block 10 is used to prevent the metal pipe from accidentally contacting the electric heating rod 7 when it moves to the inside of the lower shell 1 .

[0029] Reference Figure 1-5 , wherein an air outlet 11 communicating with the reflux chamber 6 is opened on the outside of the upper shell 4 .
