Description

Technical Field

[0001] The invention belongs to the technical field of mechanical manufacturing, and relates to a pulley processing device, in particular to a forming device for intelligent processing of pulleys. Background Art

[0002] Pulleys belong to the hub type parts and are generally relatively large in size. The manufacturing process is generally based on casting and forging. Generally, larger sizes are designed by casting, and the material is generally cast iron, and cast steel is rarely used; generally smaller sizes can be designed by forging, and the material is steel.

[0003] In the field of mechanical manufacturing, pulleys, as a key transmission component, are widely used in various types of mechanical equipment. With the acceleration of the process of industrial automation, higher requirements are placed on the production efficiency and quality of pulleys. However, the existing intelligent processing forming devices for pulleys still have many shortcomings. The existing devices are not sufficiently automated, the connection between the various processes is not smooth enough, and the production efficiency is low. At the same time, the coordination between the various mechanisms of the equipment is not perfect, and there is a problem of operational interference, which reduces the overall production efficiency.

[0004] After searching, it is found that a pulley forming mold with a weight-reducing hole is disclosed in a Chinese patent document [Application No.: 202221569829.X; Publication No.: CN218050203U]. This pulley forming mold with a weight-reducing hole includes a lower mold, a pulley forming seat is movably installed inside the lower mold, a positioning column is fixed inside the pulley forming seat by welding, a mold core is sleeved on the surface of the positioning column, a slide groove is opened inside the lower mold, a pulley forming outer mold is slidably connected inside the slide groove, the front end of the pulley forming outer mold extends to the inside of the pulley forming seat, the front side surfaces of the pulley forming outer mold are in contact with the inner wall of the pulley forming seat, and the end surface of the pulley forming outer mold is in contact with the inner wall of the slide groove.

[0005] Although a pulley forming mold with a weight-reducing hole disclosed in the patent opens a slide groove in the lower mold, and sets a pulley forming outer mold in the slide groove, and cooperates with a pull ring to facilitate the pulley forming outer mold to be pulled out from the pulley forming seat after the pulley is cast, which is beneficial to the demolding of the pulley after molding. However, the pulley forming mold with a weight-reducing hole has a low degree of automation, and requires manual pulling of the pull ring to pull the pulley forming outer mold out of the pulley forming seat, and requires a hydraulically driven or pneumatically driven die pressing device, and can only be used in specific scenarios.

[0006] Therefore, we propose a forming device for intelligent processing of pulleys. Through the cooperation of various mechanisms, the pulley can efficiently and automatically carry out a series of forming processes such as casting, mold closing, cooling molding, mold opening and taking finished products. Summary of the invention

[0007] The purpose of the present invention is to address the above-mentioned problems in the existing technology and to propose a molding device for intelligent processing of pulleys.

[0009] The working principle of the present invention is as follows: the molten material in the furnace is injected into the lower mold cavity located in the casting area. After the casting is completed, the operations on each station are completed. The transfer mechanism rotates intermittently to rotate the lower mold after the injection to the next station. After reaching the mold closing area, the upper mold manipulator moves the upper mold to the upper part of the lower mold in the mold closing area for mold closing. After the mold closing is completed, the upper mold manipulator returns to the finished product material taking area. At this time, the transfer mechanism rotates again to rotate the mold after mold closing to the cooling area. The cold air blower conveys cold air to the air distributor. The air distributor conveys the cold air to the cold air channel 1 inside the lower mold, and then enters the cold air channel 2 inside the upper mold, and finally discharges it to cool the molten material in the mold and accelerate the forming of the pulley. When the cooling process is over, the transfer mechanism rotates the cooled mold to the finished product picking area, and the upper mold manipulator moves downward to grab the upper mold. After grabbing, the upper mold manipulator moves upward and moves to the mold closing area. At this time, the finished product manipulator moves to the finished product picking area, and the chuck power mechanism controls the four-jaw chuck to open, driving the lower mold to open the mold. The finished product manipulator moves downward, takes out the formed pulley from the mold, and places it on the conveyor.

At this time, the casting of the lower mold in the casting area is completed, and the transfer mechanism rotates again to rotate the closed lower mold to the casting area, and repeat the above process. At the same time, the cold air fan delivers cold air to the cooling mechanism, and the cooling mechanism cools the pulley on the conveyor for a second time to ensure that it meets the temperature and performance required by the process.

A cooling box air inlet connector 47 is provided on the side of the cooling box 48. The cooling box air inlet connector 47 is connected to the air outlet of the air cooler through a pipeline.

[0058] In this embodiment, the cold air generated by the air cooler enters the cooling box 48 from the cooling box air inlet joint 47 through a pipe. When the finished product pulley on the conveyor 9 is transported to the inside of the cooling box 48, the cold air in the cooling box 48 cools it down. The wind shield curtain 49 can reduce the leakage of cold air and ensure a better cooling environment in the cooling box 48.

[0059] The working principle of the present invention is as follows: the molten material in the furnace is injected into the cavity of the lower mold 1 located in the pouring area. After the pouring is completed, the operations at each station are completed. The output shaft of the cam divider 20 drives the upper transfer tray 19 to rotate intermittently, and the lower mold 1 after the injection is completed is rotated to the next station. The universal wheel rod 21 and the universal wheel 18 play a supporting role and flexibly move to a suitable position with the transfer tray 19. After reaching the mold closing area, the movable guide rail frame 32 provides support, the driving shaft of the screw motor 2 41 drives the screw seat 2 51 to rotate, and the screw seat 2 51 is connected to the screw 34, so that the movable block 2 40 moves on the screw 34, and the upper mold 11 is moved to the upper part of the lower mold 1 in the mold closing area. The telescopic end of the lifting hydraulic cylinder 2 36 drives the mechanical clamp 2 to move downward, and the mechanical clamp 2 opens to complete the loosening action of the upper mold 11, thereby completing the mold closing operation of the upper mold 11 and the lower mold 1. The positioning hole 28 cooperates with the positioning column 15 to achieve precise positioning. After the mold closing is completed, the upper mold manipulator 6 returns to the finished product material taking area; The output shaft of the cam divider 20 drives the indexing tray 19 at the upper end to rotate intermittently again, and rotates the mold after mold closing to the cooling zone. The cold air blown by the cold air machine enters the main pipe 25 through the rotating joint 26 and reaches the air distributor body 23. The cold air entering the air distributor body 23 is evenly distributed to all directions and reaches each air distribution pipe 24. The cold air passes through the air distribution pipe 24 and enters the side mold 12 through the side mold air inlet joint 16, flows in the cold air channel 1, and then enters the upper mold air inlet hole 29 from the side mold air outlet joint 14, flows in the cold air channel 2, and cools the pulley in the molding process. Finally, the hot air is discharged from the upper mold air outlet joint 30 for other purposes, which cools the molten material in the mold and accelerates the molding of the pulley. The counterweight block 31 above the upper mold body 27 increases the weight of the upper mold 11 to ensure the stability and tightness of the mold closing. When the cooling process is finished, the output shaft of the cam divider 20 drives the upper indexing tray 19 to rotate the cooled mold to the finished product picking area, and the mobile guide frame 32 To provide support, the lifting hydraulic cylinder 2 36 works, and its telescopic end drives the mechanical clamp 2 to move downward. The mechanical clamp 2 opens to complete the grabbing action of the upper mold 11, thereby completing the grabbing operation of the upper mold 11. After grabbing, the lifting hydraulic cylinder 2 36 works, and its telescopic end drives the mechanical clamp 2 to move upward. The active shaft of the screw motor 2 41 drives the screw seat 2 51 to rotate, and the screw seat 2 51 is connected to the screw rod 34 in transmission, so that the moving block 2 40 moves on the screw rod 34 and moves to the mold clamping area. At this time, the active shaft of the screw motor 1 38 drives the screw seat 1 50 to rotate, and the screw seat 1 50 is connected to the screw rod 34 in transmission, so that the moving block 1 39 slides horizontally on the screw rod 34, and the finished product manipulator 8 moves to the finished product picking area. The telescopic end of the mobile electric push rod 42 drives the moving seat 46 to move on the power frame 44, thereby driving the rotating motor and the power connecting rod 45 to move, and the two sets of limit sensors 43 are used To limit the moving range of the moving seat 46, the power connecting rod 45 is inserted into the adjusting gear rod 17 of the four-claw chuck 2 at the corresponding position, and the rotating motor drives the power connecting rod 45 to rotate clockwise, thereby driving the claws 22 to open, which is used to open the side mold 12. The lifting hydraulic cylinder 35 works, and its telescopic end drives the mechanical clamping claw 37 to move downward. The mechanical clamping claw 37 opens to complete the grabbing action of the finished product, and the molded pulley is taken out of the mold and placed on the conveyor 9. The telescopic end of the mobile electric push rod 42 drives the moving seat 46 to move on the power frame 44, thereby driving the rotating motor and the power connecting rod 45 to move. Two sets of limit sensors 43 are used to limit the moving range of the moving seat 46. The power connecting rod 45 is inserted into the adjusting gear rod 17 of the four-claw chuck 2 at the corresponding position, and the rotating motor drives the power connecting rod 45 to rotate counterclockwise, thereby driving the claws 22 to clamp, so that the claws 22 drive the side mold 12 to close the mold again; At this time, the casting of the lower mold 1 in the casting area is completed, and the output shaft of the cam divider 20 drives the upper indexing tray 19 to rotate again, and the lower mold 1 after mold closing is rotated to the casting area, and the above process is repeated. At the same time, the cold air generated by the cold air fan enters the cooling box 48 from the cooling box air inlet joint 47 through the pipeline. When the finished product pulley on the conveyor 9 is transported to the inside of the cooling box 48, the cold air in the cooling box 48 is cooled for the second time. The wind shield curtain 49 can reduce the leakage of cold air, ensure that there is a better cooling environment in the cooling box 48, and ensure that it meets the temperature and performance required by the process.

[0060] In summary, the lower mold 1, the four-jaw chuck 2 and the chuck power mechanism 7 cooperate to control the lower mold 1 to close the mold for easy casting, or control the lower mold 1 to open the mold to take out the finished pulley; Through the cooperation of the lower mold 1 and the upper mold 11, the two are precisely positioned and cooperated to form a complete molding cavity when the molds are closed. At the same time, after the molds are closed, the cold air channels inside the two are connected to cool the pulley during molding; The four-claw chuck 2 and the lower mold 1 are driven to rotate to various workstations through the indexing mechanism 4, so as to promote a series of production links such as pouring, mold closing, cooling and molding, and mold opening to take finished products. At the same time, the indexing mechanism 4 cooperates with the air distributor 3 to ensure stable connection when the indexing mechanism 4 rotates to avoid cold air leakage; The cooling fan, the air distributor 3, the lower mold 1 and the upper mold 11 cooperate to realize the cooling and molding of the molten material in the mold; The cooling fan, the cooling mechanism 10 and the conveyor 9 cooperate to cool the finished product on the belt wheel of the conveyor 9, so as to facilitate the subsequent handling; The upper mold manipulator 6 and the finished product manipulator 8 cooperate with the movable guide rail mechanism 5 respectively. The movable guide rail mechanism 5 drives the upper mold manipulator 6 to grab the upper mold 11 to perform mold closing and transfer operations. The movable guide rail mechanism 5 drives the finished product manipulator 8 to take out the molding pulley and place it on the subsequent conveyor 9.
