[0023] In the exemplary embodiments, as shown in Figure 1 , 2 The embodiment provides a large-capacity anodic oxidation metal workpiece baking oven, which comprises a baking oven body 1, the bottom of the baking oven body 1 is fixedly connected with a supporting box 2, a plurality of air inlets 3 communicating inside and outside are formed in the supporting box 2, and a filter screen can be arranged in the air inlets 3; a baking cavity 4 and a heating cavity 5 arranged in an up-down mode are arranged in the baking oven body 1, the heating cavity 5 comprises a plurality of heating cavities arranged side by side, adjacent heating cavities 5 are separated by a first partition plate 6, and a plurality of electric heating pipes 7 are arranged in each heating cavity 5; a plurality of air guide fans 8 are further arranged on the top of the baking oven body 1 and are arranged in an up-down mode opposite to each heating cavity 5 and are communicated with the baking cavity 4; a communication frame 9 is arranged between the supporting box 2 and each heating cavity 5, and a plurality of first communication holes 10 are arranged between each heating cavity 5 and the baking cavity 4.

[0024] In the above embodiment, the baking cavity 4 provided in the baking oven body 1 is the space where baking is performed, a plurality of heating cavities 5 are provided below, and a plurality of air guides 8 are provided above the heating cavities 5. When the air guides 8 are operated, negative pressure is generated in each heating cavity 5 through the baking cavity 4, so that external air enters each heating cavity 5, is heated by the electric heating pipe 7, and then forms hot air that enters the baking cavity 4. In this way, hot air can be efficiently and uniformly introduced into each part of the larger baking cavity 4. Therefore, the baking oven body 1 in the present scheme can be provided with a larger capacity, i.e., the baking cavity 4 can be provided to be larger, such as a rectangle as a whole. The metal workpiece 11 is hung on the hanger 12 and then sent into the baking cavity 4, so that a large number of metal workpieces 11 can be baked at the same time. Therefore, the problem of low overall efficiency caused by the small capacity of the baking oven and the need for batch baking in the prior art is solved.

[0025] As shown in Figure 1 , 2 , in order to facilitate the entry and exit of the hanger 12 and the metal workpiece 11, a closing door 25 is further provided on one side of the baking oven body 1. The hanger 12 can enter and exit the baking cavity 4 through this place. The capacity is larger, so that multiple hangers 12 can be put in at the same time to bake more metal workpieces 11. Further, in order to facilitate the positioning of the hanger 12, a locking member 13 is further provided between the bottom of each hanger 12 and the inner bottom of the baking cavity 4. More specifically, the locking member 13 includes a first horizontal plate 14 and a first vertical plate 15 which are combined into an L-shaped structure.

The first connecting rod 16 can be a screw rod. In this way, the positioning of the locking member 13 and the baking cavity 4 can be achieved, and the hanger 12 is indirectly positioned in the baking cavity 4. In particular, in order to prevent the locking member 13 from blocking the hanger 12, the hanger 12 can be sent into the baking cavity 4 first, and then the locking member 13 is installed.

[0026] As shown in Figure 1 , 3As shown, the hanger 12 in the scheme can be lifted into the baking cavity 4, in order to facilitate the movement of the hanger 12, the baking oven body 1 is also fixedly connected with a supporting block 17 located below the opening and closing door 25, the supporting block 17 is overlapped with an inclined plate 18 and the lower end of the inclined plate 18 extends obliquely downward, the inclined plate 18 arranged in this way plays the role of a bridge, facilitating the movement of the hanger 12; more specifically, the higher end of the inclined plate 18 is fixedly connected with a second horizontal plate 19 and a second vertical plate 20 which enclose a "7" shape, the second horizontal plate 19 can abut against the top surface of the supporting block 17, the second vertical plate 20 is detachably connected with the side surface of the supporting block 17 through a second connecting rod 21, the second connecting rod 21 can also be a screw rod, the second horizontal plate 19 covers the supporting block 17, and the second vertical plate 20 is fixed through the second connecting rod 21, so that the inclined plate 18 can be fixed, and at the same time, this also makes the higher end of the inclined plate 18 more stable, ensuring the safety of the movement of the hanger 12.

[0027] As shown in the drawings, Figures 1-4 As shown, the baking cavity 4 is also fixedly connected with a baffle 22 on the top, the baffle 22 is uniformly provided with a plurality of second communication holes 23, the baffle 22 is arranged above the opening and closing door 25, when the induced draft fan 8 is running, the hot air in the baking cavity 4 needs to pass through the second communication holes 23 to enter the induced draft fan 8 again, avoiding the hot air being sucked into the induced draft fan 8 in a stream, more specifically, the second communication holes 23 can be arranged in a ring shape and can surround the hanger 12 below, and the first communication hole 10 can be located directly below the hanger 12, so that the hot air in the baking cavity 4 can cover the metal workpieces 11 on the hanger 12 more evenly, and therefore the efficiency can be further improved; more specifically, the baking cavity 4 and each heating cavity 5 are respectively provided with a second partition plate 24, the first communication hole 10 is arranged on the second partition plate 24, and the orthographic projection of each hanger 12 can fully cover each second partition plate 24, so that the second communication holes 23 are located directly below each hanger 12, and the upwardly introduced hot air can better contact the metal workpieces 11 on the hanger 12.
