DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1

[0022] During the normalizing process of the gear forging, the gear forging needs to be placed in the heating furnace 304 for rapid heating and then subjected to heat preservation treatment. At present, when people use the heating furnace 304 for normalizing of the forging, they need to manually place the gear forging into the heating furnace 304, and then take it out for cooling after the normalizing is completed, which cannot achieve continuous operation. In order to solve this defect in the prior art, Figure 1-Figure 4As shown, this embodiment proposes a gear forging for a reduction gear box, which can automatically carry out horizontal conveying and normalizing processing on the forging body, realizing continuous operation, which can not only improve efficiency but also improve safety of use. A forging conveying mechanism 2 for feeding is provided on the mounting seat 1 of the device, and a forging body 5 is placed on the forging conveying mechanism 2. A normalizing treatment mechanism 3 for heating the forging is provided on the back of the forging conveying mechanism 2, and an automatic feeding mechanism 4 is arranged above the forging conveying mechanism 2. After the worker puts the forging body 5 into the automatic feeding mechanism 4, the automatic feeding mechanism 4 will put the forging body 5 into the forging conveying mechanism 2 in sequence, and then the normalizing treatment mechanism 3 will normalize the forging body 5.

[0023] In order to reduce the labor intensity of workers and improve the processing efficiency of normalizing, specifically, a left mounting frame 201 and a right mounting frame 202 are symmetrically installed on the upper end of the mounting seat 1, and a driving motor for driving a conveying shaft 203 is fixedly installed on the right mounting frame 202. When the forging is normalized, the conveying shaft 203 can rotate intermittently under the action of the driving motor, thereby conveying the forging body 5 to the bottom of the heating furnace 304 in turn. The left mounting frame 201 and the right mounting frame 202 are respectively installed with conveying shafts 203, and a conveyor belt 204 is arranged between the two conveying shafts 203. A plurality of avoidance slots 205 are opened at equal intervals on the conveyor belt 204. When the conveyor belt 204 moves under the action of the conveying shaft 203, the forging body 5 will be horizontally conveyed.

[0024] In order to prevent workers from being burned during manual material discharge and to improve the efficiency of normalizing, specifically, a rectangular vertical plate 301 is fixedly installed on the upper end of the mounting seat 1, and a mounting platform 302 is fixedly installed on the front of the rectangular vertical plate 301. An ejector assembly 303 for lifting the forging body 5 is provided on the mounting platform 302. The ejector assembly 303 includes a pneumatic push rod fixedly installed on the mounting platform 302. The infrared sensor 305 is electrically connected to the pneumatic push rod through a wire. A circular gasket is fixedly installed on the upper end of the pneumatic push rod. The size of the circular gasket matches the avoidance groove 205. When the pneumatic push rod extends upward, the circular gasket will extend upward from the inside of the avoidance groove 205. A temperature-adjustable heating furnace 304 is arranged above the ejection assembly 303. Infrared sensors 305 for positioning are arranged around the outer side of the ejection assembly 303. When the infrared sensor 305 detects that the ejection assembly 303 is coaxial with the avoidance groove 205, the ejection assembly 303 will automatically extend upward, thereby ejecting the forging body 5 into the interior of the heating furnace 304.

[0025] If the staff manually puts the gear forgings 5 ​​onto the conveyor belt 204 one by one and makes them located above the avoidance slot 205, not only the feeding accuracy cannot be guaranteed, but also the workload will be greatly increased. For this, mounting rods 401 are symmetrically arranged on the front and rear sides of the conveyor belt 204, and a rectangular box 402 is fixedly mounted on the mounting rods 401. A circular channel 403 is vertically opened at the upper end of the rectangular box 402, and a vertical conveying member 404 for vertically conveying the forging body 5 is arranged inside the side wall of the circular channel 403. A limiting protrusion 405 for clamping the forging body 5 is arranged on the vertical conveying member 404. After the worker puts the forging body 5 into the circular channel 403, the limiting protrusion 405 will limit the forging body 5. Next, the vertical conveying member 404 will put the forging body 5 onto the conveyor belt 204 one by one.

[0026] In this embodiment, during the normalizing process of the forging, the worker will first place the forging body 5 into the circular channel 403. Figure 4 As shown, after the forging body 5 is placed in, the limiting protrusions 405 on both sides will support the forging body 5. Next, the limiting protrusions 405 will move downward a certain distance under the action of the vertical conveyor 404. Then, the worker will place another forging body 5 into the circular channel 403, and repeat this process until the circular channel 403 is filled with forging bodies 5.

[0027] Next, each time the vertical conveyor 404 rotates, a forging body 5 will fall onto the conveyor belt 204. After falling, the forging body 5 will intermittently move to the right along with the conveyor belt 204. When the forging body 5 moves to the bottom of the heating furnace 304, the ejector assembly 303 will automatically extend upward under the control of the infrared sensor 305, thereby pushing the forging body 5 into the interior of the heating furnace 304 for normalizing processing.

[0028] After the normalizing process is completed, the ejector assembly 303 will shrink downward, so that the normalized forging body 5 returns to the conveyor belt 204. Then, the conveyor belt 204 will continue to move to the right, thereby transporting another forging body 5 to the bottom of the heating furnace 304. At the same time, the normalized forging body 5 will be naturally cooled on the conveyor belt 204.

[0029] This embodiment provides a forging conveying mechanism 2 and a normalizing treatment mechanism 3, and utilizes the mutual cooperation between the ejection assembly 303 and the avoidance groove 205 to automatically horizontally convey and normalize the forging body 5, thereby realizing continuous operation without the need for manual material placement by the staff, which can effectively improve the efficiency of the normalizing process and avoid burns to the staff; in addition, this embodiment provides an automatic feeding mechanism 4, and utilizes the mutual cooperation between the vertical conveying member 404 and the limiting protrusion 405 to automatically place the forging body 5 on the conveyor belt 204 in sequence, thereby ensuring that the forging body 5 is just located above the avoidance groove 205, which can effectively improve the processing efficiency and improve the accuracy of the forging placement position.

The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
