Description

Technical Field

[0001] The utility model relates to the technical field of gear shaft forging processing devices, in particular to a gear shaft forging processing device for a speed reducer box. Background Art

[0002] The prior art discloses a gear shaft forging processing device with the publication number of CN218001129U for a speed reducer. When processing the gear shaft forging, the metal residues generated on the metal surface are blocked by the inserting plate and the cover plate during the splashing process, so as not to affect the surrounding workers.

[0003] However, when using this gear shaft forging processing device, since the metal is hot processed, metal scraps will fall off the metal surface during the processing, and the metal scraps have a certain volume and weight and cannot be sucked away by the dust suction component in this gear shaft forging processing device. As a result, the metal scraps accumulate on the surface of the metal processing workbench and come into contact with the metal during the metal processing. And due to the setting of its protection component, it is not convenient for workers to manually clean the metal scraps on the workbench surface, thus affecting the hot processing of the metal. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a gear shaft forging processing device for a speed reducer box, which solves the technical problem that metal scraps accumulate on the workbench and affect the hot processing of the metal, and achieves the purpose of conveniently cleaning the metal scraps on the workbench surface.

[0005] To solve the above technical problems, the utility model provides the following technical solutions:

[0006] A gear shaft forging processing device for a speed reducer box includes a workbench and a protection component installed on the upper end of the workbench. A cleaning mechanism for cleaning the metal scraps on the workbench surface is arranged in the workbench.

[0007] The cleaning mechanism includes an air pump arranged on one side of the workbench. An air pipeline one is arranged at the output end of the air pump. A connecting part is arranged at one end of the workbench and is threadedly connected with the air pipeline one. Two air pipelines two are threadedly connected in the connecting part. One ends of the two air pipelines two are respectively provided with spray heads located on both sides of the workbench.

[0008] Further, a circular cavity is arranged in the connecting part. A spherical ball is rotatably connected in the circular cavity.

A rotating rod penetrating through the connecting part and extending to the outside is arranged at the upper end of the spherical ball. A rotating part for driving the spherical ball to rotate reciprocally in the circular cavity is arranged at one end of the rotating rod.

[0009] Further, the two second air pipelines are on the same horizontal line, and the first air pipeline is perpendicular to the second air pipeline in terms of position.

[0010] Further, the rotating member includes a motor provided on one side of the workbench. An internal gear is provided at the end of the output shaft of the motor. A first gear meshing with the internal gear is provided at one end of the rotating rod. A second gear meshing with the middle part of the internal gear is meshed on the surface of the first gear.

[0011] Further, the tooth grooves on the surface of the second gear and the internal gear are one-fourth of the tooth grooves of the first gear.

[0012] Further, grooves for loading metal scraps are provided on both sides of the workbench, and push plates for pushing the metal scraps to move are provided in the grooves.

[0013] By means of the above technical solution, the present utility model provides a gear shaft forging processing device for a speed reducer, which at least has the following beneficial effects:

[0014] 1. Due to the setting of the cleaning mechanism in the present utility model, the outside air is continuously pressurized by an air pump and then conveyed to the connecting part. The internal gear and the second gear are driven to rotate by the motor, so that the first gear drives the ball to rotate back and forth by 90 degrees in the circular cavity, enabling the air source to enter the two second air pipelines successively. Under the action of the nozzle, the metal scraps on the surface of the workbench are blown and moved away from the metal to be processed, which is beneficial to isolating the cooled metal scraps from the gear shaft forging and preventing damage to the metal surface.

[0015] 2. Due to the setting of the grooves in the present utility model, the metal scraps separated from the surface of the workbench are collected, further preventing the metal scraps from contacting the gear shaft forging. At the same time, the worker pushes the push plate to push the metal scraps in the groove out, so that the metal scraps are transferred out of the internal part of the gear shaft forging processing device, which is beneficial for the worker to clean the metal scraps of the gear shaft forging processing device.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] When the gear shaft forging processing device processes hot metal, first place the metal to be processed on the workbench and start cutting and processing the metal. During the hot processing, the metal residues generated on the metal surface are intercepted by its protection component during the splashing process, thereby preventing it from affecting the surrounding workers. And the particulate dust during the metal processing process will be absorbed by its dust suction component, so as not to affect the respiratory systems of the surrounding workers. The surface of the hot-processed metal will be accompanied by the dropping of metal scraps, which will accumulate on the workbench and are prone to being squeezed against the metal during the metal cutting process, resulting in damage to the processed metal surface, which is not conducive to the processing of gear shaft forgings. Based on this, the following solutions are provided.

[0025] Embodiment 1

[0026] When the gear shaft forging processing device performs cutting hot processing on the gear shaft forging, the metal scraps dropped from its metal surface cannot be removed and will accumulate on the workbench surface, thus affecting the further processing of the gear shaft forging. This embodiment provides a gear shaft forging processing device for a speed reducer, as Figures 1-3As shown in the figure, it includes a workbench 1 and a protective component 2 installed on the upper end of the workbench 1. A cleaning mechanism 3 for cleaning the metal waste on the surface of the workbench 1 is provided inside the workbench 1. When the staff places the metal to be processed on the surface of the workbench 1 and starts the hot processing treatment, the metal residues generated on the metal surface will be blocked by the protective mechanism, and will not affect the surrounding staff. Moreover, the metal waste falling from the metal surface will, under the action of the cleaning mechanism 3, remove the metal waste from the surface of the workbench 1, preventing the metal waste from cooling and hardening, thus avoiding mutual extrusion with the gear shaft forging during the processing and resulting in loss of the metal surface.

[0027] The cleaning mechanism 3 includes an air pump 31 provided on one side of the workbench 1, which can suck the air in the external environment into the air pump 31 and transport it to the first air pipeline 32 after pressurization. The output end of the air pump 31 is provided with the first air pipeline 32. One end of the workbench 1 is provided with a connecting part 33 threadedly connected to the first air pipeline 32, which can adjust the air source transported by the air pump 31 so that the air source enters one of the second air pipelines 34 in sequence. Two second air pipelines 34 are threadedly connected inside the connecting part 33, enabling the platforms on both sides of the workbench 1 to spray gas successively. One end of each of the two second air pipelines 34 is provided with a nozzle 35 located on both sides of the workbench 1, and the sprayed gas acts on the surface of the workbench 1 to blow the metal waste on the surface of the workbench 1 to move. Since when this gear shaft forging processing device is working, a large amount of metal waste is generated on the surface of the gear shaft forging and will accumulate on the surface of the workbench 1. At this time, the air pump 31 continuously sucks the external air into the air pump 31, transports it to the connecting part 33 through the first air pipeline 32 after pressurization, and realizes switching inside the connecting part 33, so that the air source enters the two second air pipelines 34 in sequence and orderly. Under the action of the nozzles 35, the metal waste on the surface of the workbench 1 is removed, isolating the metal waste from the metal to be processed, which is beneficial to the processing and forming of the gear shaft forging.

[0028] Since the high-pressure external gas conveyed by the air pump 31 acts on the surface of the workbench 1 after being ejected from the nozzles 35, when the nozzles 35 on both sides work simultaneously, the metal waste on the surface of the workbench 1 is basically in the middle and is still in contact with the metal. When only one side of the nozzles 35 works, there will be certain dead corners when the metal waste moves on the surface of the workbench 1, resulting in the inability to normally remove the metal waste from the surface of the workbench 1. A circular cavity 331 is provided in the connecting part 33. A spherical ball 332 is rotatably connected in the circular cavity 331. An L-shaped through groove 333 in contact with the first air pipeline 32 and the second air pipeline 34 is provided in the spherical ball 332. A sealing gasket 334 in contact with the second air pipeline 34 is provided in the circular cavity 331. A rotating rod 335 passing through the connecting part 33 and extending to the outside is provided at the upper end of the spherical ball 332. A rotating member 336 for driving the spherical ball 332 to reciprocally rotate in the circular cavity 331 is provided at one end of the rotating rod 335. Since the first air pipeline 32 is perpendicular to the straight line where the two second air pipelines 34 are located at the position where the first air pipeline 32 is connected to the connecting part 33, when the spherical ball 332 reciprocally rotates by 90 degrees in the circular cavity 331, one of the two second air pipelines 34 remains unobstructed from the first air pipeline 32 under the action of the L-shaped through groove, and the other second air pipeline 34 is blocked by the surface of the spherical ball 332 and the sealing gasket 334, so that the air source does not enter the other second air pipeline 34. It is beneficial for the air source to enter one of the second air pipelines 34 successively, so that the nozzles 35 on both sides of the workbench 1 eject airflows successively to remove the metal waste on the surface of the workbench 1.

[0029] Since it is necessary to control the spherical ball 332 to reciprocally rotate 90 degrees within the circular cavity 331 of the connecting part 33, enabling the gas source to orderly enter the two second gas pipeline 34 successively, a rotating member 336 is provided to make the spherical ball 332 reciprocally rotate 90 degrees orderly within the circular cavity 331. The rotating member 336 includes a motor 3361 arranged on one side of the workbench 1. An internal gear 3362 is provided at the end of the output shaft of the motor 3361. A first gear 3363 meshing with the internal gear 3362 is provided at one end of the rotating rod 335. A second gear 3364 fixedly connected to the middle of the internal gear 3362 meshes with the surface of the first gear 3363. Since the output shaft of the motor 3361 continuously rotates the internal gear 3362, the internal gear 3362 and the second gear 3364 rotate coaxially. And since the tooth grooves of the second gear 3364 and the internal gear 3362 are one-fourth of the tooth grooves of the first gear 3363, when the first gear 3363 meshes with the second gear 3364, the second gear 3364 drives the first gear 3363 to rotate one-fourth of a circle. When the first gear 3363 meshes with the internal gear 3362, the internal gear 3362 drives the first gear 3363 to rotate reversely one-fourth of a circle. Thus, the first gear 3363 drives the rotating rod 335 to reciprocally rotate, which is conducive to controlling the spherical ball 332 to drive the L-shaped through groove 333 to rotate within the circular cavity 331, and is conducive to controlling the gas source to enter the two second gas pipeline 34 successively.

[0030] Embodiment 2

[0031] When the airflow ejected by the nozzle 35 blows the metal waste on the surface of the workbench 1 to both sides of the workbench 1, a large amount of metal waste will accumulate on both sides of the workbench 1 and need to be cleaned manually. In the processing of gear shaft forgings, and restricted by this protection component 2, it is not conducive for workers to remove the metal waste on both sides of the workbench 1. On the basis of Embodiment 1, Figure 4 As shown, grooves 36 for loading metal waste are provided on both sides of the workbench 1, and a push plate 37 for pushing the metal waste to move is provided in the grooves 36. After the metal waste on the surface of the workbench 1 is blown by the airflow ejected by the nozzle 35, it enters the grooves 36 on both sides of the workbench 1. Workers only need to push the push plate 37 to move within the grooves 36, thereby clearing the metal waste accumulated in the grooves 36 from this gear shaft forging processing device to the outside, which is conducive for workers to collect and process the metal waste generated during the gear shaft forging processing.
