[0014] like Figure 1As shown, an automatic purging device for a bevel gear forging die comprises a die set, a purging device, and a moving mechanism; the die set comprises an upper die set and a lower die set which are symmetrically arranged up and down, the lower die set is fixedly connected to the moving mechanism, the upper die set is rotatably connected to the moving mechanism, a purging device is provided on the moving mechanism, and an output end of the purging device is located between the upper die set and the lower die set; when the upper die set moves away from / approaches the lower die set, it drives the moving mechanism to move towards / away from the die set, and drives the purging device to purge different positions of the die set.

[0015] Specifically, the inclined link 1 8 is fixed to the lower mold plate 1, the vertical link 3 9 fixedly connected to the inclined link 1 8, and the horizontal link 10 fixedly connected to the vertical link 3 9, all remain relatively stationary with the lower mold. The upper mold is fixedly set on the upper half of the press and can move in the vertical direction with the upper half of the press. The lower mold is fixedly set on the lower half of the press, and the lower half of the press is fixedly set on the ground. The upper mold is rotatably connected to the inclined link 2 6, and the movable end of the inclined link 2 6 is connected to the movable rod 13, and the movable rod 13 is connected to the movable ends of the vertical link 1 11 and the vertical link 2 12. When the upper mold moves upward, it will drive the connected inclined link 2 6 to rotate clockwise, and the movable end of the inclined link 2 6 will drive the movable rod 13, the movable end of the vertical link 1 11, and the movable end of the vertical link 2 12 to approach the gap between the upper mold and the lower mold, thereby driving the purge device to move from right to left (such as Figure 1 As shown in the direction, the air nozzle 1402 will blow out high-pressure gas to remove the debris between the upper die set and the lower die set; when the upper die set moves downward, it will drive the connected inclined connecting rod 2 6 to rotate counterclockwise, and the active end of the inclined connecting rod 2 6 will drive the active rod 13, the active end of the vertical connecting rod 1 11 and the active end of the vertical connecting rod 2 12 away from the gap between the upper die set and the lower die set, thereby driving the purge device to move from left to right (such as Figure 1 The air nozzle 1402 is moved in the direction shown in the figure until the upper mold assembly and the lower mold assembly are completely closed and the air nozzle 1402 is completely separated from the gap between the upper mold assembly and the lower mold assembly.

[0016] In addition, the lower die set includes a lower die plate 1 and a lower die base 2, and the upper die set includes an upper die base 3 and an upper die plate 4; the lower die plate 1 is fixedly arranged on the top of the lower half of the press, the lower surface of the lower die base 2 is fixedly connected to the upper surface of the lower die plate 1, the upper surface of the upper die base 3 is fixedly connected to the lower surface of the upper die plate 4, and the die plate 4 is fixedly connected to the bottom of the upper half of the press and moves with the upper half of the press moving up and down; a connecting plate 7 is provided on one side of the lower die plate 1, and the connecting plate 7 is fixedly connected to the moving mechanism; the upper die plate 4 is provided with a connecting plate 2 5, and the connecting plate 2 5 is on the same side as the connecting plate 7, that is, Figure 1The connecting plate 1 7 and the connecting plate 2 5 are both on the right side (they can also be on other sides, and it needs to be ensured that the two are on the same vertical line), and the connecting plate 2 5 can be rotatably connected to the movement mechanism.

[0017] In addition, the motion mechanism includes a horizontal connecting rod 10 arranged horizontally, the two ends of the horizontal connecting rod 10 are rotatably connected to the vertical connecting rod 11 and the vertical connecting rod 2 12, the middle of the horizontal connecting rod 10 is fixedly connected to one end of the vertical connecting rod 3 9 arranged vertically, the other end of the vertical connecting rod 3 9 is fixedly connected to one end of the tilting connecting rod 1 8, and the other end of the tilting connecting rod 1 8 is fixedly connected to the lower mold group; the vertical connecting rod 1 11 and the vertical connecting rod 2 12 are rotatably connected to the movable rod 13, the movable rod 13 is rotatably provided with one end of the tilting connecting rod 2 6, and the other end of the tilting connecting rod 2 6 is rotatably connected to the upper mold group. The horizontal connecting rod 10 plays a fixed supporting role, the ends of the vertical connecting rod 11 and the vertical connecting rod 2 12 connected to the horizontal connecting rod 10 are the corresponding fixed ends, and the other ends are the movable ends, and the movable ends of the vertical connecting rod 11 and the vertical connecting rod 2 12 can move in a circle around the corresponding fixed ends under the drive of the movable rod 13.

[0018] Furthermore, the horizontal link 10, the movable link 13, the vertical link 11, the vertical link 2 12, the vertical link 3 9, the inclined link 1 8 and the inclined link 2 6 are provided with a plurality of through holes 18 in the length direction, and the through holes 18 are used to adjust the connection position of each link with other links. In general, it is mainly to adjust the position of the through holes 18 at the connection points of the movable link 13, the vertical link 11 and the vertical link 2 12. The through holes 18 on the vertical link 11 and the vertical link 2 12 are used to adjust the vertical height of the movable link 13 (i.e. the vertical height of the air pipe 1401), and the through holes 18 on the movable link 13 are used to adjust the horizontal position of the air pipe 1401. By adjusting the position of the through holes 18 on the three and limiting by the latch, the position of the air pipe 1401 / air nozzle 1402 can reach an ideal state. The ideal state is: when the upper module and the lower module are closed, the air nozzle 1402 is exactly located as follows: Figure 1 As shown in the figure, on the right side of the lower die base 2 and the upper die base 3, when the upper die set gradually rises, the air nozzle 1402 will gradually move to the left between the lower die base 2 and the upper die base 3. When the upper die set rises to the maximum distance, the air nozzle 1402 can be located at the leftmost position of the lower die base 2 and the upper die base 3. It is worth noting that when the upper die set rises to the maximum distance, the tilting connecting rod 26 has a certain angle with the vertical direction, and its tilting angle is rightward (such as Figure 1The angle shown in the figure) is the angle shown in the figure). At this time, when the upper die set is closed, the tilting connecting rod 2 6 can be smoothly pushed to rotate counterclockwise to push the movable rod 13 to the right so that the air nozzle 1402 can be away from the gap between the upper die set and the lower die set, so that the gap between the two can be completely closed, which is convenient for subsequent work. The perforation 18 can also be replaced with other adjustable distances and fixed adjustment methods. Another embodiment is: two sliding sleeves with fixing devices are sleeved on the movable rod 13, and the movable rod 13 can slide in the sliding sleeves, and the movable rod 13 can be fixed by the fixing device; in addition, the sliding sleeve is provided with a slider that is slidably connected to the slide rails provided on the vertical connecting rod 1 11 and the vertical connecting rod 2 12, and the slider can be fixed on the slide rails by the fixing device.

[0019] In addition, an air pipe 1401 is provided in the length direction of the movable rod 13, and a plurality of air nozzles 1402 are provided at the output end of the air pipe 1401, and the output end of the air pipe 1401 is close to the module. The input end of the air pipe 1401 is connected to an air pump (not shown), and the air pipe 1401 delivers high-pressure gas to the air nozzle 1402. The air pipe 1401 is provided with a plurality of air nozzles 1402, which can purge the debris between the upper module and the lower module at multiple angles. A more preferred setting is that the air nozzles 1402 on the air pipe 1401 are rotatably arranged.

[0020] In addition, a laser distance measuring device 17 is provided on the lower surface of the upper mold plate 4, and the laser distance measuring device 17 is connected to the solenoid valve. The laser distance measuring device 17 can be placed on any one of the upper mold group and the lower mold group, and the optimal setting is a vertical setting. In this example, the output end of the laser distance measuring device 17 directly irradiates the lower mold group, and the distance when the upper mold group and the lower mold group are closed is set as the initial distance, and whether the distance between the upper mold group and the lower mold group changes is detected. When the distance between the upper mold group and the lower mold group is not the initial distance (that is, when the upper mold group starts to slide on the slide rail 1601), the laser distance measuring device 17 sends an open signal to the solenoid valve, and at this time, the high-pressure gas can pass through the air pipe 1401 to the air nozzle 1402. When the upper mold group and the lower mold group are completely closed, the laser distance measuring device 17 sends a closed signal to the solenoid valve, and at this time, the high-pressure gas cannot pass through the air pipe 1401 to the air nozzle 1402.

[0021] Working principle: Gear forging dies will produce waste during the forging process. When the die is opened, the waste needs to be purged. When the die is opened, the upper die set slides upward, driving the tilted link 2 6 to rotate clockwise, and the tilted link 2 6 drives the air pipe 1401 / air nozzle 1402 of the movable rod 13 to move to the left. At the same time, the laser distance measuring device 17 detects the position change and controls the solenoid valve to open the gas passage. The high-pressure gas blows the waste between the upper die set and the lower die set along the air pipe 1401 to the air nozzle 1402; when the upper die set slides downward, driving the tilted link 2 to rotate counterclockwise, the tilted link 2 6 drives the air pipe 1401 / air nozzle 1402 of the movable rod 13 to move to the right. When the upper die set and the lower die set are completely closed, the laser distance measuring device 17 detects that it is the initial distance and controls the solenoid valve to close the gas passage.

[0022] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, modifications, and substitutions made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
