Description

Technical Field

[0001] The present invention relates to the technical field of transmission chain component forging, and more particularly to a pre-forging device for transmission chain forging production. Background Art

[0002] In the field of drive chain forging production, drive chain components are key components, and their quality and performance play a decisive role in the stability and reliability of the entire transmission system. Currently, cold forging is widely used in the production process of drive chain components. The cold forging process can produce plastic deformation of metal materials at room temperature, thereby giving the drive chain components the desired shape and certain mechanical properties, such as improving the strength and hardness of the components, so that they can better withstand the loads during operation.

[0003] However, in existing technology, operators often manually clean and polish the surfaces of cold-forged transmission chain components using brushes, sandpaper, and other tools to remove iron filings. This method is inefficient, and the cleaning effect is significantly affected by the operator's proficiency and responsibility, making it difficult to ensure that every component is thoroughly and evenly cleaned. Furthermore, manual cleaning is labor-intensive, making it difficult to meet production schedules in large-scale production.

[0004] On the one hand, iron filings pressed into the surface of components can damage the surface finish and flatness of the components, resulting in defects such as scratches and pits on the surface. This not only affects the appearance quality of the transmission chain components, but more importantly, it can reduce the precision of the fit between the components and other parts, increase the difficulty and errors in the assembly process, and thus affect the transmission efficiency and stability of the entire transmission system. For example, in a high-speed transmission system, surface defects may cause increased friction between the transmission chain components and adjacent components, generating additional heat and vibration, accelerating component wear, and shortening the service life of the equipment. On the other hand, if iron filings are pressed into the interior of the components, they will form microscopic defects or stress concentration areas. When the transmission chain components are subjected to working loads, these defective areas are prone to become the initiation source of cracks. With the repeated action of the load, the cracks will gradually expand, eventually leading to serious failure forms such as component fracture, posing a great threat to the safe operation of the equipment.

DETAILED DESCRIPTION

[0024] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0026] See also Figure 1-12 , the present invention provides the following technical solutions: Example 1, see Figure 1-Figure 4 A transmission chain pre-forging device for forging production includes a housing 1, an electromagnet 2 disposed on top of the housing 1 for placing a transmission chain component to be processed, and a forging device 3 disposed beside the housing 1 for forging the cleaned transmission chain component. The transmission chain pre-forging device also includes a pre-cleaning flipping mechanism 4 for cleaning the transmission chain component. The specific structure of the pre-cleaning flipping mechanism 4 is as follows; See Figure 1-Figure 7 The pre-cleaning flipping mechanism 4 is arranged at the top of the casing 1, and the pre-cleaning flipping mechanism 4 includes a displacement part 41, a flipping part 42, a first cleaning part 43 and a second cleaning part 44; the displacement part 41 is slidably arranged at the top of the casing 1; the flipping part 42 is rotatably arranged in the middle of the displacement part 41, and the top of the displacement part 41 is provided with an avoidance groove for the flipping part 42 to flip; the first cleaning part 43 has a plurality of parts and is respectively arranged at the bottom of the flipping part 42, and the plurality of first cleaning parts 43 are spaced apart; the second cleaning part 44 has a plurality of parts and is respectively slidably arranged at the top of the flipping part 42, and the plurality of second cleaning parts 44 are spaced apart.

[0027] Specifically, a rotary motor for controlling the flipping of the flipping portion 42 is provided on both sides of the displacement portion 41. The rotary motor is preferably a servo motor. When the rotary motor is started, the flipping portion 42 can be controlled to be in a flipping state. A pair of abutment portions for controlling the flipping portion 42 to remain horizontal after flipping is provided on both sides of the displacement portion 41. A telescopic cylinder is also provided on both sides of the displacement portion 41 for driving the abutment portions to move toward the top and bottom of the flipping portion 42, respectively. When the flipping portion 42 flips and the first cleaning portion 43 is located above the electromagnet 2, the telescopic cylinder is started and drives the abutment portions to abut against the top and bottom of the flipping portion 42, respectively, so that the flipping portion 42 can remain horizontal with the displacement portion 41 after flipping, ensuring that the first cleaning portion 43 and the second cleaning portion 44 can stably contact the surface of the transmission chain component. The material of the first cleaning portion 43 is preferably a nylon brush. The nylon brush can effectively contact and clean the transmission chain component to be cleaned placed on the electromagnet 2, and can reduce contact damage to the surface of the transmission chain component to be cleaned. After the transmission chain components are cleaned by the first cleaning part 43, the cleaned transmission chain components are then clamped and transported to the position of the forging device 3 by the clamping and transporting method of the robot arm for forging processing. After the first cleaning part 43 cleans the transmission chain components to be cleaned, the displacement part 41 rises, and then the flip part 42 flips, until the second cleaning part 44 flips to the position of the first cleaning part 43, and then the displacement part 41 descends. A displacement sensor for controlling the descending distance of the displacement part 41 is provided inside the casing 1, and the movement stops when the distance between the second cleaning part 44 and the electromagnet 2 is ≤2mm. Then the electromagnet 2 is closed, and the material of the second cleaning part 44 is preferably the electromagnet 2. When the second cleaning part 44 is close to the position of the electromagnet 2, the second cleaning part 44 can adsorb the iron filings attached to the electromagnet 2, so that after the first cleaning part 43 is cleaned, the iron filings attached to the electromagnet 2 can be effectively cleaned by the second cleaning part 44.

[0028] See Figure 3-Figure 5 The pre-cleaning flipping mechanism 4 also includes a first sliding portion 45, a first connecting portion 46, a guide portion 47 and a return spring 48; the first sliding portion 45 has multiple and is respectively slidably arranged at the bottom of the flipping portion 42, and the multiple first sliding portions 45 are all located at the bottom of the first cleaning portion 43; the first connecting portion 46 has multiple and is respectively arranged on both sides of the first sliding portion 45, and the multiple first connecting portions 46 are used to fixedly connect the multiple first sliding portions 45; the guide portion 47 has multiple and is respectively arranged at the bottom of the flipping portion 42, and the multiple guide portions 47 are clearance-matched with the first sliding portion 45; the return spring 48 is arranged on the outside of the guide portion 47, one end of the return spring 48 is fixedly connected to the flipping portion 42, and the other end of the return spring 48 is fixedly connected to the first sliding portion 45.

[0029] Specifically, the first sliding portion 45 can slide stably along the guide portion 47 when moving, and when the first sliding portion 45 slides, it can drive multiple first sliding portions 45 to move synchronously and the first cleaning portion 43 to move synchronously through the first connecting portion 46, until one of the first sliding portions 45 contacts the return spring 48, the return spring 48 is in a compressed state, and can push the first sliding portion 45 in contact with the return spring 48 back to the initial position.

[0030] See Figure 4-Figure 6 The pre-cleaning flipping mechanism 4 also includes a mounting portion 49, a contact portion 491 and a limiting portion 492; the mounting portion 49 is arranged at the top of the first sliding portion 45, and the mounting portion 49 is located next to the first cleaning portion 43; the contact portion 491 is arranged next to the first cleaning portion 43 and is located below the mounting portion 49; the limiting portion 492 is arranged at the top of the flipping portion 42, and both sides of the contact portion 491 are provided with abutment grooves that contact the contact portion 491, and when the contact portion 491 slides, it can be in abutment with the limiting portion 492.

[0031] Specifically, when the first sliding part 45 is lifted and reset by the return spring 48, the first sliding part 45 can drive the contact part 491 to move synchronously until the contact part 491 contacts the limiting part 492 set on the flipping part 42. At this time, the first sliding part 45 stops moving. Through the setting of the return spring 48 and the limiting part 492, multiple first sliding parts 45 can slide back and forth between the limiting part 492 and the return spring 48.

[0032] See Figure 4-Figure 7 The pre-cleaning flipping mechanism 4 also includes a first rotation driver 493 and a rotating portion 494; the first rotation driver 493 is arranged at the top of the flipping portion 42, and the first rotation driver 493 is located next to the mounting portion 49; the rotating portion 494 is arranged at the output end of the first rotation driver 493, and the rotating portion 494 can rotate along its own axis and contact the contact portion 491, driving the contact portion 491 to be in a sliding state.

[0033] Specifically, in order to drive multiple first cleaning parts 43 to remove limited iron filings from the surface of the transmission chain component to be cleaned on the electromagnet 2, the first rotary driver 493 is started and drives the rotating part 494 to rotate. When the rotating part 494 rotates, it can contact the contact part 491. When in contact, it can drive the contact part 491 and the first sliding part 45 to move, and notify the first connecting part 46 to drive the multiple first sliding parts 45 to move, ensuring the synchronization of the movement of the multiple first sliding parts 45. When the rotating part 494 does not contact the contact part 491, the return spring 48 pushes the first sliding part 45 and the contact part 491 to move until the contact part 491 contacts the limiting part 492 and stops moving, realizing the reciprocating sliding of the first cleaning part 43, which can effectively clean the iron filings on the surface of the transmission chain component.

[0034] In the second embodiment, after the first cleaning part 43 is cleaned, a lot of iron filings and impurities will adhere to the interior of the first cleaning part 43 , which will affect the cleaning effect of the first cleaning part 43 on the transmission chain components after the cold forging process.

[0035] To this end, an air pump 495 and an air blowing pipe 496 are provided on the top of the turning portion 42. Figure 4 The pre-cleaning flipping mechanism 4 also includes an air pump 495 and an air blowing pipe 496; there are multiple air pumps 495 and they are respectively arranged at the bottom of the flipping part 42, and the multiple air pumps 495 are all located beside the first cleaning part 43; there are multiple air blowing pipes 496 and they are respectively arranged at the output end of the air pump 495, and the multiple air blowing pipes 496 are all located beside the first cleaning part 43.

[0036] Specifically, when the first cleaning part 43 moves back and forth for cleaning, the air pump 495 is started during this process and the air is discharged through the blowing pipe 496, so that when the first cleaning part 43 cleans the transmission chain components on the electromagnet 2, multiple blowing pipes 496 facing the first cleaning part 43 can blow some of the iron filings generated during the cleaning process out of the outside of the first cleaning part 43, ensuring the cleanliness of the first cleaning part 43 and increasing the service life of the first cleaning part 43, thereby improving the use effect of the first cleaning part 43.

[0037] See Figure 1 The pre-cleaning flipping mechanism 4 also includes a moving part 497 and a receiving part 498; the moving part 497 has multiple parts and is slidably arranged on the top of the flipping part 42, and the multiple moving parts 497 are all located below the second cleaning part 44 and fixedly connected to the second cleaning part 44; the receiving part 498 has multiple parts and is respectively arranged on the side of the moving part 497, and the multiple receiving parts 498 are used to connect the multiple moving parts 497 at intervals.

[0038] Specifically, when the moving portion 497 moves, the plurality of second cleaning portions 44 can be driven to move synchronously via the plurality of receiving portions 498 .

[0039] See Figure 8 The pre-cleaning flipping mechanism 4 also includes a rotating part 499, a setting part 4901 and a hinged rod 4902; the rotating part 499 is rotatably set at the top of the flipping part 42, and the rotating part 499 is located next to the first rotation driver 493; the setting part 4901 is installed next to the second cleaning part 44 and is located on one side of the rotating part 499; the hinged rod 4902 is set at the top of the rotating part 499, one end of the hinged rod 4902 is rotatably connected to the rotating part 499, and the other end of the hinged rod 4902 is rotatably connected to the setting part 4901.

[0040] Specifically, after the transmission chain component is cleaned by the first cleaning part 43 and the iron filings attached to the electromagnet 2 need to be cleaned, the displacement part 41 first drives the flipping part 42 to rise, and then the flipping part 42 flips and positions the second cleaning part 44 above the electromagnet 2. In this state, the distance between the second cleaning part 44 and the electromagnet 2 is sufficient so that the iron filings on the electromagnet 2 can be adsorbed by the second cleaning part 44. When the rotating part 499 rotates, it can drive the setting part 4901 to move by rotating the hinged rod 4902 connected thereto, and when the setting part 4901 moves, it can drive one of the moving parts 497 to move, and then the moving part 497 drives multiple moving parts 497 to move through the receiving part 498, thereby realizing the reciprocating movement of multiple second cleaning parts 44.

[0041] See Figure 7 The pre-cleaning flipping mechanism 4 also includes a first gear 4903 and a second gear 4904; the first gear 4903 is arranged at the output end of the first rotation driver 493, and the first gear 4903 is located below the rotating part 494; the second gear 4904 is arranged outside the rotating part 499 and meshes with the first gear 4903.

[0042] Specifically, when the first rotation driver 493 is started, it can drive the first gear 4903 to rotate, and when the first gear 4903 rotates, it can rotate the engaged second gear 4904, and when the second gear 4904 rotates, it can drive the rotating part 499 to rotate, thereby achieving a reciprocating sliding effect on the second cleaning part 44.

[0043] Embodiment 3 is to clean the iron filings attached to the second cleaning portion 44 without affecting the subsequent cleaning of the electromagnet 2 by the second cleaning portion 44 .

[0044] See Figure 3The collecting mechanism 5 includes a centrifuge 51, a collecting box 52, a dust suction pipe 53 and a connecting cover 54; the centrifuge 51 is arranged at the top of the casing 1; the collecting box 52 is arranged at the top of the casing 1 and is located next to the centrifuge 51, and the collecting box 52 is connected to the centrifuge 51 through a pipe; the dust suction pipe 53 is arranged at the top of the casing 1, and the dust suction pipe 53 is connected to the collecting box 52; the connecting cover 54 is arranged at the bottom of the dust suction pipe 53, and the connecting cover 54 is located above the flip part 42.

[0045] Specifically, after the second cleaning section 44 absorbs the iron filings attached to the electromagnet 2, the displacement section 41 rises and the flip section 42 flips until the second cleaning section 44 is located below the connecting cover 54. The centrifuge 51 is then started and the iron filings adsorbed on the second cleaning section 44 are collected through the connecting cover 54 and the dust suction pipe 53. During this process, the second cleaning section 44 is closed, allowing the iron filings to be sucked into the interior of the collection box 52 by the suction force of the connecting cover 54 and the dust suction pipe 53. The connection between the collection box 52 and the dust suction pipe 53 can be configured to prevent the iron filings from being sucked into the filter screen inside the centrifuge 51, thereby achieving effective cleaning of the second cleaning section 44 and ensuring the stable use of the second cleaning section 44 in subsequent work.

[0046] See Figure 11 and Figure 12 A first linear drive 6 and a limiting portion 7 are also provided on the top of the casing 1; the first linear drive 6 is provided at the top of the casing 1 and has a pair; there are multiple limiting portions 7 and they are respectively provided at the bottom of the casing 1, and the multiple limiting portions 7 are all clearance-matched with the displacement portion 41.

[0047] Specifically, a ball screw is provided at the output end of the first linear actuator 6. This ball screw is threadedly connected to the displacement unit 41 and is used to drive the displacement unit 41 upward or downward. When the displacement unit 41 needs to be driven upward or downward, the first linear actuator 6 is activated and drives the ball screw to rotate. In this state, the displacement unit 41 can move upward or downward under the control of the limiting unit 7.

[0048] Obviously, the embodiments described above are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.
