[0032] Furthermore, the front end of the connecting rod 24 is fixedly connected to a transmission wheel 21 near the rear of the fixed plate 2 for driving the chain 28 for transmission. The left side of the transmission wheel 21 is connected to a driven wheel 23 through the chain 28 for driving the chain 28 to drive the transmission. The pushing assembly includes a push plate 25 that pushes the metallurgical part to the right for oil immersion and then pushes it out along the arc surface. The bottom of the inner wall of the oil immersion tank 1 is rotatably connected to a roller 210, and the bottom of the inner wall of the oil immersion tank 1 is rotatably connected to a rotating rod 29 near the upper left of the roller 210. A group of rotating rods 29 is arranged above the two groups of rollers 210, so that the metallurgical part can be stably supported by the rolling of multiple groups of rollers 210 and multiple groups of rotating rods 29, while reducing the friction of the metallurgical part movement and improving the transmission effect.

[0033] Reference Figure 1 、 Figure 2 and Figure 3A pump body 5 is provided on the rear surface of the oil immersion tank 1, and a filter box is provided on the left side of the pump body 5, through which the oil can be transferred into the filter box for filtration. A connecting pipe 32 connecting the collecting frame 33 and the pump body 5 is fixedly connected to the right side of the pump body 5. A recovery component is provided on the right side of the oil immersion tank 1, and the recovery component includes a collecting frame 33 that can collect the oil dropped from the conveyor belt 3. The upper part of the inner wall of the collecting frame 33 is close to the right side of the oil immersion tank 1 with a conveyor belt 3 that continues to transport the metallurgical parts after being immersed in oil backward.

[0034] Reference Figure 2 、 Figure 3 and Figure 4 The top end of the push plate 25 is slidably connected to a buffer plate 27 that can prevent the metallurgical parts from being squeezed and stuck, and the bottom end of the buffer plate 27 is fixedly connected to a positioning plate 211 that supports the buffer plate 27.

[0035] Reference Figure 1 、 Figure 2 and Figure 3 There are multiple groups of fixed plates 2 and connecting rods 24, and the multiple groups of fixed plates 2 and connecting rods 24 are symmetrically arranged with the center line of the oil immersion tank 1 as the axis of symmetry, which can effectively provide support. The left and right sides of the inner wall of the oil immersion tank 1 are set to arcuate surfaces, which can facilitate the metallurgical parts to slide down and move out. The driven wheel 23 is fixedly connected to the outer wall of another group of connecting rods 24, and two groups of chains 28 are set. The two groups of chains 28 drive multiple groups of push plates 25 to move. The right top of the right side of the oil immersion tank 1 near the right side of the arcuate surface is set to an inclined surface. Setting it as an inclined surface can facilitate the metallurgical parts to slide down along the inclined surface to be transmitted to the conveyor belt 3.

[0036] Furthermore, the push plate 25 is fixedly connected between the two groups of chains 28 and multiple groups of push plates 25 are provided. The multiple groups of push plates 25 can effectively push the metallurgical parts to be immersed in oil. There are multiple groups of rotating rods 29 and rollers 210, and the multiple groups of rotating rods 29 and rollers 210 are arranged in an array with each other. The arrangement can effectively support the metallurgical parts while reducing the friction of the metallurgical parts, thereby improving the transmission effect. The outer wall of the conveyor belt 3 is provided with a through hole 31 and multiple groups are provided. The other end of the connecting pipe 32 passes through and is fixedly connected to the rear surface of the collecting frame 33. The oil on the metallurgical parts can be dropped downward along the through hole 31 into the collecting frame 33 through the through hole 31, thereby effectively collecting the oil on the metallurgical parts.

[0037] Reference Figure 1 、 Figure 3 and Figure 4The bottom end of the positioning plate 211 is fixedly connected to a spring 26, and the other end of the spring 26 is fixedly connected to the bottom end of the inner wall of the push plate 25. The positioning plate 211 is slidably connected to the inner wall of the push plate 25. When the metallurgical part squeezes the buffer plate 27, it drives the positioning plate 211 to move and squeeze the spring 26, preventing the metallurgical part from being directly stuck, thereby improving flexibility.

[0038] Working principle: When in use, first connect the external power supply and switch to the electrical equipment in the device, and convey the metallurgical parts through the conveyor belt 4. After being conveyed to the left top of the oil immersion tank 1, it falls downward along the arc surface of the oil immersion tank 1 to the top of the roller 210 and the rotating rod 29 in the oil immersion tank 1. The metallurgical parts can be immersed in oil by storing oil in the oil immersion tank 1. At this time, the motor 22 is started to drive the connecting rod 24 and the transmission wheel 21 to rotate, and the transmission wheel 21 drives the chain 28 and the motor 22 to transmit, and the chain 28 drives the push plate 25 to move. The metallurgical parts are pushed to the right by moving the push plate 25 at the bottom, and the metallurgical parts move along the top of the roller 210 and the rotating rod 29. The multiple sets of rollers 210 and the rotating rod 29 can reduce the friction with the metallurgical parts, thereby improving the transmission efficiency. When it is pushed to the right side of the oil immersion tank 1, the right inner wall of the oil immersion tank 1 is set as an arc surface, and it can continue to push upward along the arc surface. After being pushed to the top of the right side, it moves to the right and slides downward along the inclined surface on the right side to the conveyor belt 3, and the metallurgical parts that have fallen and been immersed in oil are transmitted through the conveyor belt 3.

[0039] Furthermore, by opening a plurality of through holes 31 on the outer wall of the conveyor belt 3, the oil dripping from the metallurgical parts can continue to drip downwards into the collecting frame 33 for collection, so that the oil on the metallurgical parts can be pre-treated. At the same time, the oil is collected and transferred to the pump body 5 through the connecting pipe 32, and then further transferred to the filter box for filtration, which facilitates collection, recovery and recycling, thereby preventing the waste of oil on the metallurgical parts and further improving the automation effect and production efficiency. At this time, the metallurgical parts can be immersed in oil and transferred, which can be fully automated and does not require manual operation, thereby improving production efficiency.
