[0016] The present utility model will be further described below in conjunction with specific embodiments, and the advantages and features of the present utility model will become clearer as the description progresses. However, these embodiments are merely exemplary and do not constitute any limitation to the scope of the present utility model. Those skilled in the art should understand that modifications or substitutions can be made to the details and forms of the technical solutions of the present utility model without departing from the spirit and scope of the present utility model, and these modifications and substitutions all fall within the protection scope of the present utility model.

[0017] Refer to Figures 1 to 4, the utility model relates to an automatic production line for hot die forging. Along the running direction of the production line, it includes an automatic feeding mechanism 4, a horizontal cylinder pusher 2 of the heating furnace, a vertical cylinder pusher 1 of the heating furnace, an intermediate frequency heating furnace 3, a conveying slideway 5, a horizontal cylinder pusher 8 of the roll forging machine, a vertical cylinder pusher 6 of the roll forging machine, a roll forging machine 9, a first robot 14, a friction press 15, a second robot 18, a vertical cylinder pusher 19, a punching press 20 and a horizontal cylinder pusher 21 for pushing the edge. The automatic feeding mechanism 4 is used to send the blank to the horizontal cylinder pusher 2 of the heating furnace; the horizontal cylinder pusher 2 of the heating furnace is used to send the blank to the vertical cylinder pusher 1 of the heating furnace, and the vertical cylinder pusher 1 of the heating furnace is used to send the blank into the intermediate frequency heating furnace 3 for heating and then push it out to the conveying slideway 5. The conveying slideway 5 is used to send the blank to the horizontal cylinder pusher 8 of the roll forging machine, the horizontal cylinder pusher 8 of the roll forging machine is used to send the blank to the vertical cylinder pusher 6 of the roll forging machine, and the vertical cylinder pusher 6 of the roll forging machine is used to send the blank into the roll forging machine 9. The roll forging machine 9 is used to roll the blank into two roll forging semi-finished products 11 with a preset shape and output them to the material receiving bucket 12 through the output component 13. Among them, after the two roll forging semi-finished products 11 roll down freely, their positions are variable and not fixed, and the positions are inaccurate, so the robot cannot capture them. To enable the robot to smoothly catch the roll forging semi-finished products after rolling, the two roll forging semi-finished products need to be placed in the material receiving bucket 12 respectively, and the roll forging semi-finished products have the same direction and are placed vertically at a fixed position. It is very difficult to achieve the roll forging semi-finished products after rolling, so an output component 13 is added during the sliding process of the roll forging semi-finished products after rolling by the roll forging machine; the first robot 14 is used to grab the roll forging semi-finished products and transport them to the hot die forging press 15, and the hot die forging press 15 is used for the forming of the roll forging semi-finished products to form a formed product; the second robot 18 is used to grab the formed product and move it to the punching press 20, and the punching press 20 is used to cut the edge of the formed product; the vertical cylinder pusher 19 is used to push the formed product with the cut edge into the product container, and the horizontal cylinder pusher 21 is used to push the edge into the edge container.

[0018] Based on the above structure setting of the utility model, the following are realized:

[0019] High degree of automation: Through equipment such as the automatic feeding mechanism, various cylinder pushers, conveying slideways, robots, etc., a fully automated production process from feeding to finished product output is realized.

[0020] High production efficiency: The automatic production line reduces manual operation, reduces production time and cost, and improves production efficiency.

[0021] Stable product quality: Automatic control reduces human errors, ensures the consistency of product size and shape, and improves product quality.

[0022] Operation safety: The direct manual operation is reduced, and the safety risk during the operation process is lowered.

[0023] The output component 13 is arranged at the discharge port of the rotary forging machine 9. The output component includes a blanking plate 25, a partition plate 27, side guard plates 26 and guide plates 28. Side guard plates 26 are respectively arranged on both sides of the blanking plate 25. A partition plate 27 is installed in the middle of the blanking plate 25 between the two side guard plates 26. An output space 10 for one rotary forging semi-finished product is formed between the partition plate 27 and one of the side guard plates 26, and another output space 10 for the rotary forging semi-finished product is formed between the partition plate and the other side guard plate; Several inclined guide plates 28 are arranged along the length direction of each side guard plate 26 on the inner side of the side guard plate 26, and a spacing is formed between adjacent two guide plates 28. The rotary forging semi-finished product 11 falls along the output space 10 and slides into the material receiving bucket 12 in the order of the small end downwards under the action of the guide plates 28. The large end is upwards, which is convenient for the robot to grasp and the placing direction of the blank for the next process is with the large end upwards.

[0024] One end of each guide plate 28 is connected to the side guard plate 26, and the other end forms an arc-shaped guiding end, which is inclined downwards. The arc-shaped guiding end can smoothly guide the material or workpiece to move along a predetermined path, reducing the friction and resistance during the movement process; The arc-shaped design helps the material or workpiece to pass through smoothly, reducing the risk of jamming or blocking, especially in an automated production line.

[0025] Several top plates 29 are installed at the upper part between the two side guard plates 26. Adjacent two top plates 29 are parallel to each other and form a spacing.

[0026] The working principle of the utility model is:

[0027] The automatic feeding mechanism 4 sends the blank to the lateral cylinder pusher 2 of the heating furnace. The lateral cylinder pusher 2 of the heating furnace sends the blank to the longitudinal cylinder pusher 1 of the heating furnace. The longitudinal cylinder pusher 1 of the heating furnace sends the blank to the intermediate frequency heating furnace 3 for heating. At the same time, the previous blank is pushed out. The blank is sent to the lateral cylinder pusher 8 of the rotary forging machine through the transfer slideway 5. The lateral cylinder pusher 8 of the rotary forging machine sends the blank to the longitudinal cylinder pusher 6 of the rotary forging machine. The longitudinal cylinder pusher 6 of the rotary forging machine sends the blank into the rotary forging machine 9. After rotary forging, two rotary forging semi-finished products 11 are formed. The rotary forging machine rolls the blank into two rotary forging semi-finished products with a certain shape. After the two rotary forging semi-finished products roll down freely, they slide into the material receiving bucket 12 in the order of the small end down under the action of the output component 13. The large end is up, which is convenient for the robot to grasp and the placement direction of the blank for the next process is with the large end up. According to the program, the first robot Ⅰ 14 grabs a rotary forging semi-finished product 11 and sends it into the forging lower die 17 of the hot die forging press 15 (before putting it in, the first robot 14 sprays graphite agent on the upper and lower dies). The forging upper die 16 moves down to cooperate with the forging lower die 17 to complete the product forming. After the forging upper and lower dies open and close, the second robot 18 grabs the formed product and moves it into the trimming lower die 23 of the punching press 20. The trimming upper die 22 moves down to cooperate with the trimming lower die 23 to complete the trimming process. When the trimming upper and lower dies open and close, the product longitudinal cylinder pusher 19 pushes the formed product into the product container, and the lateral cylinder pusher for trimming edge 21 pushes the trimming edge into the trimming edge container. Thus, the hot die forging automatic production line completes one cycle.

[0028] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
