Abstract
Description
Technical Field
[0001] This utility model relates to the field of cold forging technology of transmission chains, and more specifically, it relates to an auxiliary device for forging transmission chains. Background Technology
[0002] In the manufacturing of aluminum alloy drivetrains, cold forging and stamping processes are receiving increasing attention and are being widely applied. Aluminum alloys, with their low density, high specific strength, and good corrosion resistance, are an ideal choice for manufacturing drivetrains. Cold forging and stamping, as an advanced metal plastic processing technology, can apply enormous pressure to aluminum alloy blanks at room temperature, causing plastic deformation and thus obtaining components with the required shape and precise dimensions.
[0003] However, in the processing steps following the cold forging and stamping of aluminum alloy drivetrain components, the die removal operation becomes a critical step restricting production efficiency and product quality. The die removal operation refers to the smooth and efficient separation of the formed aluminum alloy drivetrain component from the mold. This process, seemingly simple, actually has a vital impact on production efficiency and product quality.
[0004] Currently, in existing equipment on the market, the demolding of cold-forged transmission chain components mainly relies on manual operation or the use of some simple auxiliary tools. Manual demolding requires workers to handle and retrieve the cold-forged transmission chain, increasing their labor intensity. At the same time, manual operation is inefficient and cannot meet the needs of large-scale production. Furthermore, due to the variability of manual operation, the demolding process may damage the transmission chain components, such as scratching the surface or affecting the dimensional accuracy, thereby reducing the product qualification rate and impacting the company's economic benefits and market competitiveness. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a transmission connection forging for bulldozer tracks.
[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a housing, a lower die disposed on the top of the housing for placing the cold-forged stamping transmission chain component, and an upper die slidably disposed on the top of the housing and located above the lower die. The transmission chain forging auxiliary device further includes a de-molding mechanism and a flipping and adsorption mechanism. The de-molding mechanism is disposed on the top of the housing and includes a sliding contact part, a driving part, and a rotating part. The sliding contact part is slidably disposed on the top of the lower die, and a guide groove for limiting the sliding of the sliding contact part is provided on the top of the lower die. The driving part is slidably disposed on the top of the housing and is located beside the lower die. The rotating part is rotatably disposed beside the sliding contact part, with one end rotatably connected to the sliding contact part and the other end rotatably connected to the driving part. When the driving part is in a moving state, the rotating part can drive the sliding contact part to a rising sliding state. The flipping and adsorption mechanism is disposed on the top of the housing and is used to clamp and transfer the cold-forged stamping transmission chain component.
[0007] By adopting the above technical solution, when the transmission chain component needs to be unmolded after cold forging and stamping, the drive unit can first move inside the lower die. During this process, the drive unit can drive the sliding abutment part to rise through the rotating part connected to it, until the sliding abutment part pushes out the stamped transmission chain component from the lower die, thus completing the automatic unmolding action of the cold-forged transmission chain component. This effectively solves the problem of the transmission chain component being difficult to remove after cooling and forming, while avoiding the tedious manual handling of the cold-forged transmission chain component.
[0008] The present invention is further configured such that: the film removal mechanism also includes a first telescopic cylinder; the first telescopic cylinder is disposed on the top of the machine housing and located beside the lower mold, and the output end of the first telescopic cylinder is connected to the drive unit, and when the first telescopic cylinder is started, it can drive the drive unit to slide horizontally away from the first telescopic cylinder.
[0009] The present invention is further configured as follows: the flipping adsorption mechanism includes a guide part, a swing part, a limiting part, and a rotating part; the guide part has a pair and is respectively disposed on the top of the housing, and both guide parts are located on the side of the lower mold, and a guide groove is provided on the side of each pair of guide parts; the swing part is rotatably disposed on the side of the guide part, and a guide rail is provided on the side of the swing part; the limiting part has a pair and is respectively disposed on the side of the guide part, and a straight guide groove is provided above the limiting part; the rotating part is rotatably disposed on the side of the guide part, and the rotating part is located inside the guide groove and the guide rail respectively and is in a rotating state.
[0010] The present invention is further configured such that: the flipping adsorption mechanism also includes a displacement part; the displacement part is slidably disposed on the top of the limiting part and slidably cooperates with the linear guide groove, and a linear groove is opened in the middle of the displacement part, and the rotating part is located inside the guide groove, the guide rail and the linear groove respectively and is in a rotating state.
[0011] The present invention is further configured such that: the flipping adsorption mechanism includes a moving part, a guide rod, and a first rotary driver; the moving part is rotatably disposed on the side of the rotating part via a bearing; the guide rod is disposed on the top of the displacement part, and the moving part and the guide rod are clearance-fitted; the first rotary driver has a pair and is disposed on the side of the guide rod respectively, and the output end of the first rotary driver is connected to the swing part.

[0013] The present invention is further configured such that: a conveyor belt is provided on the top of the housing, located below the connecting part after flipping.
[0014] By adopting the above technical solution, after adsorption, the first rotary driver drives the swing part to rotate away from the lower die until the vacuum chuck adsorbs and transfers the cold-forged and stamped transmission chain component to the top of the conveyor belt. Then the conveyor belt starts to complete the transportation of the cold-forged and stamped transmission chain component.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0028] 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 one of ordinary skill in the art to which this application pertains.
[0029] Please see Figure 1-4 The present invention provides the following technical solution:
[0030] Embodiment 1 includes a housing 1, a lower die 2 disposed on the top of the housing 1 for placing the cold forging stamping transmission chain components, and an upper die 3 slidably disposed on the top of the housing 1 and located above the lower die 2. The transmission chain forging auxiliary device further includes a demolding mechanism 4 and a flipping adsorption mechanism 5. The demolding mechanism 4 is disposed on the top of the housing 1 and includes a sliding contact part 41, a driving part 42, and a rotating part 43. The sliding contact part 41 is slidably disposed on the top of the lower die 2, and the top of the lower die 2 has a guide groove for limiting the sliding of the sliding contact part 41. The driving part 43 is located on the top of the housing 1. Part 42 is slidably disposed on the top of housing 1, and drive part 42 is located beside lower die 2; rotating part 43 is rotatably disposed beside sliding contact part 41, one end of rotating part 43 is rotatably connected to sliding contact part 41, and the other end of rotating part 43 is rotatably connected to drive part 42. When drive part 42 is in a moving state, rotating part 43 can drive sliding contact part 41 to a rising sliding state; flipping adsorption mechanism 5 is disposed on the top of housing 1. Flipping adsorption mechanism 5 is used to clamp and transfer the cold forging transmission chain component after cold forging and stamping. The top of housing 1 is provided with a hydraulic cylinder for driving upper die 3 and lower die 2 to perform stamping action. When the hydraulic cylinder is started, it can drive upper die 3 to move towards lower die 2 and stamp the cold forging transmission chain component placed in lower die 2.
[0031] Firstly, when the cold-forged transmission chain is placed on top of the lower die 2, to reduce the friction between the cold-forged transmission chain and the lower die 2 after stamping, and to solve the adhesion problem between the cold-forged transmission chain and the lower die 2, a water-based polymer release agent can be pre-applied to the contact surface between the lower die 2 and the component. This reduces the increased friction between the cold-forged transmission chain and the lower die 2 when the upper die 3 is stamped. The drive unit 42 can drive the sliding abutment part 41 to rise through the rotating part 43 connected to it, until the sliding abutment part 41 ejects the stamped transmission chain component from the lower die 2, thus completing the automatic unloading action of the cold-forged transmission chain component. This effectively solves the problem of manually handling the cold-forged transmission chain component after stamping, and avoids the tedious operation of manually handling the cold-forged transmission chain component.
[0032] See Figure 3 and Figure 4 The film removal mechanism 4 also includes a first telescopic cylinder 44; the first telescopic cylinder 44 is disposed on the top of the housing 1 and located beside the lower mold 2, and the output end of the first telescopic cylinder 44 is connected to the drive unit 42. When the first telescopic cylinder 44 is started, it can drive the drive unit 42 to a horizontal sliding state away from the first telescopic cylinder 44.
[0033] After the upper mold 3 and the lower mold 2 are opened, the first telescopic cylinder 44 is activated and drives the drive part 42 to slide close to the sliding contact part 41. During this process, the drive part 42 can drive the rotating part 43 to flip. Since the other end of the rotating part 43 is rotatably connected to the sliding contact part 41, the rotating part 43 can drive the sliding contact part 41 to rise when it flips, thereby automatically ejecting the transmission chain component after cold forging and stamping.
[0034] See Figures 5-7 The flipping adsorption mechanism 5 includes a guide part 51, a swing part 52, a limiting part 53, and a rotating part 54. The guide part 51 is a pair and is respectively disposed on the top of the housing 1. Both guide parts 51 are located on the side of the lower mold 2, and a guide groove is provided on the side of each pair of guide parts 51. The swing part 52 is rotatably disposed on the side of the guide part 51, and a guide rail is provided on the side of the swing part 52. The limiting part 53 is a pair and is respectively disposed on the side of the guide part 51, and a straight guide groove is provided above the limiting part 53. The rotating part 54 is rotatably disposed on the side of the guide part 51, and the rotating part 54 is located inside the guide groove and the guide rail and is in a rotating state.
[0035] First, the swing part 52 rotates, and then the swing part 52 rotates. During this process, the rotating part 54 can rotate within the guide rail opened on the swing part 52 and rotate within the guide groove opened on the guide part 51. Then, when the swing part 52 is in a rotating state, the rotating part 54 can be driven to rotate and slide through the guide groove and guide rail with the groove opening restricted.
[0036] See Figures 5-7 The flipping adsorption mechanism 5 also includes a displacement part 55; the displacement part 55 is slidably disposed on the top of the limiting part 53 and slidably cooperates with the straight guide groove, and a straight groove is opened in the middle of the displacement part 55, and the rotating part 54 is located inside the guide groove, the guide rail and the straight groove and is in a rotating state.
[0037] When the swinging part 52 rotates and drives the rotating part 54 to rotate, the rotating part 54 engages with the guide groove, the guide rail and the straight groove respectively. This allows the rotating part 54 to rotate along the inside of the straight groove on the displacement part 55. During this process, the displacement part 55 is driven to move up and down along the straight guide groove on the limiting part 53. This converts the rotation state of the swinging part 52 relative to the rotating part 54 into the vertical movement state of the displacement part 55.
[0038] See Figures 5-7The flipping adsorption mechanism 5 also includes a moving part 56, a guide rod 57, and a first rotary driver 58; the moving part 56 is rotatably disposed on the side of the rotating part 54 via a bearing; the guide rod 57 is disposed on the top of the displacement part 55, and the moving part 56 and the guide rod 57 are in clearance fit; the first rotary driver 58 has a pair and is disposed on the side of the guide rod 57 respectively, and the output end of the first rotary driver 58 is connected to the swing part 52.
[0039] When the displacement part 55 is in a vertical moving state, the rotating part 54 can drive the moving part 56 to move synchronously during this process. Since the moving part 56 and the guide rod 57 provided at the top of the displacement part 55 are in clearance fit, the synchronous rotation of the rotating part 54 will drive the moving part 56 to a stable horizontal moving state without affecting the rotational motion of the rotating part 54. When the first rotary driver 58 is started, it can drive the swing part 52 to rotate.
[0040] See Figures 5-8 The flipping adsorption mechanism 5 also includes a connecting part 59, an air pump 591, and a vacuum suction cup 592; the connecting part 59 is located on the side of the moving part 56 and on the side of the lower mold 2; the air pump 591 is located on top of the connecting part 59; there are multiple vacuum suction cups 592, which are respectively located below the connecting part 59, and the multiple vacuum suction cups 592 are all connected to the air pump 591 through pipes.
[0041] When the swinging part 52 rotates and drives the moving part 56 to move, the connecting part 59 and the vacuum suction cup 592 move synchronously until the vacuum suction cup 592 is positioned above the cold-forged and stamped transmission chain component. Then, the air pump 591 starts and uses the vacuum suction cup 592 to adsorb the cold-forged and stamped transmission chain component, thus completing the adsorption and fixation of the cold-forged and stamped transmission chain component. Considering that the temperature of the aluminum alloy transmission chain after cold forging and stamping is close to 80°C, to ensure the long-term stable operation of the vacuum suction cup 592, it is preferably made of silicone material with a temperature resistance of 200°C. The silicone material vacuum suction cup 592 retains more than 95% of its elasticity at 80°C, making it suitable for long-term and continuous normal operation.
[0042] See Figures 5-8 The top of the housing 1 is provided with a conveyor belt 6 located below the flip-up connection part 59.
[0043] After adsorption, the first rotary driver 58 drives the swing part 52 to rotate away from the lower die 2 until the vacuum chuck 592 adsorbs and transfers the cold-forged and stamped transmission chain component to the top of the conveyor belt 6. Then the conveyor belt 6 starts to complete the conveying of the cold-forged and stamped transmission chain component.
[0044] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
