Its characteristic is to improve the intrinsic quality of the workpiece, which is generally not visible to the naked eye. In order to make the metal workpiece have the required mechanical properties, physical properties and chemical properties, in addition to the reasonable selection of materials and various forming processes, heat treatment processes are often indispensable.

[0043] like Figure 1 and Fig. 9 As shown, the material bin 40, hydraulic rod 42, lifting plate 43, loading rack 44 and push plate 48 are provided. The hydraulic rod 42 can be used to drive the lifting plate 43 to rise and fall, and then a single bar can be transported to the loading rack 44 at a time, and then the push rod 19 is used to push the bar to the conveying roller 8, and then the conveying roller 8 can be used to convey it. The rotary motor 46 and the screw 47 are provided to provide power for the movement of the push plate 48, that is, to push and load the bars and reset the push plate 48 for the next use. The rotating motor 49, the screw 50 and the lifting seat 51 are provided to facilitate the gradual upward transportation of the bars at the bottom of the material bin 40, to ensure normal loading, and to store a large amount of materials at one time. The length of the loading assembly can be made according to the specific length of the bars.

[0045] like Figure 3 and Figure 8 As shown, the conveying plate 52, the inclined groove 53 and the latch 54 can be arranged to adjust the height of the conveying plate 52 according to the diameter of the rod, thereby ensuring the transportation of the rod and avoiding the difference that prevents the rod from passing through the heating bin 1 normally. A high-temperature conveying device can also be arranged in the heating bin 1 according to demand to convey the rod.

[0046] When the present invention is used, the heater 9 is started, and the heater 9 heats the heating chamber 1 through the heating pipe 10. When the temperature in the heating chamber 1 is increased to a specified stable temperature, the heat treatment of the bar can be carried out;

[0047] The lifting plate 43 is started, and the bar is lifted from the silo 40 to the loading rack 44 by the lifting plate 43. Under the action of gravity, the bar rolls to the center of the loading rack 44, and then the rotating motor 46 is started, and the rotating motor 46 drives the bar to move between the two moving racks 7. Then the hydraulic cylinder 18 is started, and the hydraulic cylinder 18 drives the lifting rack 12 to descend to a suitable position through the push rod 19, that is, the conveying roller 8 stops when it contacts the surface of the bar. At this time, the rotating ball 5 driven by the clamping assembly contacts the surface of the bar, completing the center positioning clamping;

[0048] At the same time, the lifting frame 12 drives the turntable 34 to rotate via the lever 37, and the turntable 34 drives the closing plate 31 via the closing pin 36 and the closing slot 35 to gradually cover the through hole 2 until the hole between the closing plates 31 can only pass the rod;

[0049] In the process of closing the multiple closing plates 31, the closing plate 31 at the lower side drives the conveying plate 52 to move to a suitable height and then stops through the action of the latch 54 and the inclined slot 53, so as to ensure that the rods can be transported normally;

[0050] After the rod is clamped and fixed, the driving motor 25 is started, and the driving motor 25 drives the transmission rod 26 to rotate. The transmission rod 26 drives the conveying roller 8 to rotate through the hexagonal prism 27, the bevel gear 28 and the helical gear 29, so that the rod can be conveyed. The rod enters the heating bin 1 and is supported by the conveying plate 52. Then, it is heat treated by the heating tube 10. After the heat treatment, the rod is cooled in the cooling bin. After the cooling in the cooling bin is completed, drawing can be carried out. After the initial drawing, the rod can be placed in the silo 40 and wait for the secondary heat treatment before drawing. This process is repeated until all the drawing work is completed.
