Description

Technical Field

[0001] The present 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 disk hub parts. Generally, their relative sizes are relatively large. In manufacturing processes, casting and forging are mainly used. For those with relatively large sizes, casting methods are generally designed, and the materials are generally cast iron, rarely cast steel; for those with relatively small sizes, forging can be designed, and the materials are steel.

[0003] In the field of mechanical manufacturing, as a key transmission component, pulleys are widely used in various mechanical equipment. With the acceleration of the industrial automation process, higher requirements are put forward for the production efficiency and quality of pulleys. However, there are still many deficiencies in the existing forming devices for intelligent processing of pulleys. The existing devices have insufficient automation, and the connection between each process is not smooth enough, resulting in low production efficiency. At the same time, the coordinated cooperation between the various mechanisms of the equipment is not perfect enough, and there are problems of operation interference, reducing the overall production efficiency.

[0004] After retrieval, as disclosed in a Chinese patent document, a forming die for a pulley with weight-reducing holes [Application No.: 202221569829.X; Publication No.: CN218050203U]. This forming die for a pulley with weight-reducing holes includes a lower die. A pulley forming seat is movably installed inside the lower die. A positioning column is fixedly welded inside the pulley forming seat. A die core is sleeved on the surface of the positioning column. A chute is opened inside the lower die. A pulley forming outer die is slidably connected inside the chute. The front end of the pulley forming outer die extends into the pulley forming seat. The surfaces on both sides of the front end of the pulley forming outer die are in contact with the inner wall of the pulley forming seat. The surface of the end of the pulley forming outer die is in contact with the inner wall of the chute.

[0005] Although the forming die for a pulley with weight-reducing holes disclosed in this patent facilitates the extraction of the pulley forming outer die from the pulley forming seat after the pulley is cast and formed by opening a chute in the lower die and arranging the pulley forming outer die in the chute and cooperating with a pull ring, which is beneficial to the demolding of the formed pulley, however, the forming die for a pulley with weight-reducing holes has low automation. It requires manual pulling of the pull ring to extract the pulley forming outer die from the pulley forming seat, and a die pressing device driven by hydraulic pressure or pneumatic pressure can only be placed in a specific scenario.

[0006] Therefore, we propose a forming device for intelligent processing of pulleys, which can perform a series of continuous forming processes such as pouring, mold closing, cooling and forming, and mold opening to take the finished product for the pulley efficiently and automatically through the mutual cooperation of various mechanisms. Summary of the Invention

[0007] The object of the present invention is to address the above problems existing in the prior art and propose a forming device for intelligent processing of pulley. The technical problem to be solved by this invention is: how to achieve a series of continuous forming processes such as efficient and automated pouring, mold closing, cooling and forming, mold opening and finished product taking of the pulley.

[0008] The object of the present invention can be achieved by the following technical solutions:

[0009] A forming device for intelligent processing of pulley, comprising a melting furnace, a plurality of upper molds, and a indexing mechanism, a moving guide rail mechanism and a conveyor arranged in sequence from front to back. A wind distributor is provided in the middle of the indexing mechanism. The upper space of the indexing mechanism is divided into a finished product taking area, a pouring area, a mold closing area and a plurality of cooling areas. The finished product taking area, the pouring area, the mold closing area and the plurality of cooling areas are arranged circumferentially and evenly. Four-jaw chucks are provided on the finished product taking area, the pouring area, the mold closing area and the plurality of cooling areas. Lower molds are provided on the four-jaw chucks. An upper mold manipulator and a finished product manipulator are driven on the moving guide rail mechanism. The upper mold manipulator is located directly above the finished product taking area and the mold closing area. The finished product manipulator is located directly above the conveyor and the finished product taking area. The pouring area is located directly in front of the melting furnace. The melting furnace is located directly behind the moving guide rail mechanism. A chuck power mechanism and a cooling mechanism are provided on the conveyor. Upper molds are placed above the lower molds in the cooling areas. The finished product taking area is located directly in front of the chuck power mechanism. The wind distributor and the lower molds are connected by pipes. A first cold air channel is provided inside the lower mold. A second cold air channel is provided inside the upper mold. After the upper mold and the lower mold are closed, the first cold air channel and the second cold air channel are connected. Both the wind distributor and the cooling mechanism are connected to a cold air blower through pipes.

[0010] The working principle of the present invention is: Inject the molten material in the melting furnace into the cavity of the lower mold in the pouring area. After the pouring is completed, at this time, the operations at each station are completed. The indexing mechanism rotates intermittently, and rotates the lower mold filled with material to the next station. After reaching the mold closing area, the upper mold manipulator moves the upper mold to above 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 taking area. At this time, the indexing mechanism rotates again, and rotates the closed mold to the cooling area. The cold air blower delivers cold air to the wind distributor. The wind distributor delivers the cold air to the first cold air channel inside the lower mold, then enters the second cold air channel inside the upper mold, and finally discharges, cooling the molten material in the mold and accelerating the forming of the pulley;

[0011] When the cooling process ends, the indexing mechanism rotates the cooled mold to the finished product picking area. The upper mold manipulator moves downward to grasp the upper mold. After grasping, the upper mold manipulator moves upward and to the mold closing area. At this time, the finished product manipulator moves to the finished product picking area. The chuck power mechanism controls the four-jaw chuck to open, driving the lower mold to open. The finished product manipulator moves downward, takes out the formed pulley from the mold, and places it on the conveyor. The chuck power mechanism then controls the four-jaw chuck to clamp, causing the four-jaw chuck to drive the lower mold to close again. At this time, the pouring of the lower mold in the pouring area is completed. The indexing mechanism rotates again, rotating the closed lower mold to the pouring area, repeating the above process. At the same time, the cold air blower conveys cold air to the cooling mechanism, and the cooling mechanism performs secondary cooling on the pulley on the conveyor to ensure that it reaches the temperature and performance required by the process.

[0012] The indexing mechanism includes a base. A cam divider is provided at the upper end of the base. The upper end of the output shaft of the cam divider is provided with an indexing tray. The space at the upper end of the indexing tray is divided into a finished product picking area, a pouring area, a mold closing area, and several cooling areas. The finished product picking area, the pouring area, the mold closing area, and several cooling areas are arranged circumferentially and evenly. The four-jaw chuck is fixed above the indexing tray. Several circumferentially and evenly distributed universal wheel rods are fixed at the lower end of the indexing tray. The positions and numbers of the universal wheel rods correspond to those of the four-jaw chuck. Universal wheels are provided at the lower ends of the universal wheel rods.

[0013] With the above structure, the output shaft of the cam divider drives the upper indexing tray to rotate intermittently. The indexing tray drives the upper four-jaw chuck and the lower mold to pass through the finished product picking area, the pouring area, the mold closing area, and several cooling areas in sequence. The universal wheel rods and the universal wheels play a supporting role and flexibly move to the appropriate positions following the indexing tray.

[0014] The air distributor includes an air distributor body. The air distributor body is arranged at the center of the indexing tray. A main pipe connected to it is provided below the air distributor body. The main pipe penetrates the cam divider. A rotating joint is provided below the main pipe. The rotating joint is connected to the air outlet of the cold air blower through a pipeline. Several circumferentially and evenly distributed branch pipes connected to it are provided at the upper end of the main pipe.

[0015] With the above structure, the cold air blown out by the cold air blower enters the main pipe through the rotating joint, reaches the air distributor body. The cold air entering the air distributor body is evenly distributed in all directions, reaches each branch pipe, and the cold air is conveyed to the lower mold through pipeline connection.

[0016] The lower mold includes a bottom mold and four side molds evenly distributed in a circle. The bottom mold is fixed to the upper end of a four-jaw chuck, and the side molds are arranged at the upper ends of the jaws at corresponding positions of the four-jaw chuck. Among them, positioning columns are fixed to the upper ends of three side molds, and cold air sub-channels are provided inside the four side molds. After the four side molds are closed, the four cold air sub-channels are connected to form a first cold air channel. A side mold air outlet joint communicating with the cold air sub-channel inside is provided above another side mold. A side mold air inlet joint communicating with the cold air sub-channel inside is provided on the side of a side mold adjacent to the side mold with the side mold air outlet joint. The branch air pipe is connected to the corresponding side mold air inlet joint through a flexible pipe.

[0017] With the above structure, the positioning columns are used to accurately position the upper mold. The jaws of the four-jaw chuck drive the side molds to move, controlling the closing or opening of the side molds. The side molds, bottom mold and upper mold are closed to form a closed cavity. Cold air enters the side molds through the side mold air inlet joints via the branch air pipe, flows in the first cold air channel, cools the pulley during the molding process, and the cold air reaches the upper mold from the side mold air outlet joint. By controlling the inflow and discharge of cold air, the molding temperature is adjusted.

[0018] The upper mold includes an upper mold body. The upper mold body is located above the lower mold. A second cold air channel is provided inside the upper mold body. An upper mold air inlet hole matching the side mold air outlet joint is provided below the upper mold body. Three positioning holes matching the positioning columns are fixed below the upper mold body. The side mold air outlet joint is inserted into the corresponding upper mold air inlet hole. The upper mold air inlet hole is connected to the second cold air channel. A counterweight is fixed above the upper mold body. An upper mold air outlet joint communicating with the second cold air channel inside is provided on the side of the upper mold body.

[0019] With the above structure, the positioning holes cooperate with the positioning columns to achieve precise positioning. Cold air enters the upper mold air inlet hole from the side mold air outlet joint, flows in the second cold air channel, cools the pulley during the molding process, and finally the hot air is discharged from the upper mold air outlet joint for other uses, cooling the pulley in the mold in the closed mold state. The counterweight above the upper mold body increases the weight of the upper mold, ensuring the stability and tightness of the closed mold.

[0020] The moving guide rail mechanism includes a moving guide rail frame. The moving guide rail frame is in an inverted U shape. Two guide rods and a lead screw are fixed on the moving guide rail frame. The two guide rods are located on both sides of the lead screw.

[0021] With the above structure, the moving guide rail frame provides support, and the upper mold manipulator and the finished product manipulator move on the lead screw and the two guide rods.

[0022] The upper mold manipulator includes a second moving block. The second moving block is slidably arranged on two guide rods. A second screw motor is fixed below the second moving block. A second screw joint seat is arranged on the second moving block. The driving shaft of the second screw motor is in transmission connection with the second screw joint seat, and the screw rod is in transmission connection with the second screw joint seat. A second lifting hydraulic cylinder is arranged in front of the second moving block. A second mechanical claw is arranged on the telescopic end of the second lifting hydraulic cylinder.

[0023] With the above structure, the driving shaft of the second screw motor drives the second screw joint seat to rotate. The second screw joint seat is in transmission connection with the screw rod, so that the second moving block moves on the screw rod. When it moves to the specified position, the second lifting hydraulic cylinder works, and its telescopic end drives the second mechanical claw to move up and down. The second mechanical claw opens or closes to complete the grasping or releasing action of the upper mold, so as to complete the picking and placing operation of the upper mold.

[0024] The finished product manipulator includes a first moving block. The first moving block is slidably arranged on two guide rods. A first screw motor is fixed below the first moving block. A first screw joint seat is arranged on the first moving block. The driving shaft of the first screw motor is in transmission connection with the first screw joint seat, and the screw rod is in transmission connection with the first screw joint seat. A first lifting hydraulic cylinder is arranged in front of the first moving block. A first mechanical claw is arranged on the telescopic end of the first lifting hydraulic cylinder, and a heat insulation pad is arranged on the first mechanical claw.

[0025] With the above structure, the driving shaft of the first screw motor drives the first screw joint seat to rotate. The first screw joint seat is in transmission connection with the screw rod, so that the first moving block slides horizontally on the screw rod. When it moves to the specified position, the first lifting hydraulic cylinder works, and its telescopic end drives the first mechanical claw to move up and down. The first mechanical claw opens or closes to complete the grasping or releasing action of the finished product, and the material taking and placing operations are completed.

[0026] The chuck power mechanism includes a power frame. The power frame is fixed on the frame of the conveyor. A moving electric push rod is fixed on the power frame. A moving seat is slidably arranged on the power frame. The moving seat is fixedly connected with the telescopic end of the moving electric push rod. Two groups of symmetrically arranged limit sensors are fixed on the power frame. The two groups of limit sensors are located on both sides of the moving seat. A rotating motor is fixed on the moving seat. A power connecting rod is fixed on the output shaft of the rotating motor. The power connecting rod is opposite to the adjusting gear rod of the four-jaw chuck at the corresponding position.

[0027] With the above structure, the telescopic end of the moving electric push rod drives the moving seat to move on the power frame, thereby driving the rotating motor and the power connecting rod to move. The two groups of limit sensors are used to limit the moving range of the moving seat. The power connecting rod is inserted into the adjusting gear rod of the four-jaw chuck at the corresponding position. The rotating motor drives the power connecting rod to rotate, thereby driving the chuck to clamp or open, for side mold clamping or mold opening.

[0028] The cooling mechanism includes a cooling box, which is arranged above the conveyor. Wind shielding curtains are provided at both openings on the two sides of the cooling box. A cooling box air inlet joint is provided on the side of the cooling box, and the cooling box air inlet joint is connected to the air outlet of the cooling fan through a pipeline.

[0029] With the above structure, the cold air generated by the cooling fan enters the cooling box from the cooling box air inlet joint through the pipeline. When the finished pulley on the conveyor is conveyed into the interior of the cooling box, the cold air in the cooling box cools it. The wind shielding curtains can reduce the leakage of cold air and ensure a good cooling environment inside the cooling box.

[0030] Compared with the prior art, the forming device for intelligent processing of pulleys has the following advantages:

[0031] Through the cooperation of the lower die, the four-jaw chuck and the chuck power mechanism, the closing of the lower die is controlled to facilitate pouring, or the opening of the lower die is controlled to take out the finished pulley.

[0032] Through the cooperation of the lower die and the upper die, when they are closed, they are accurately positioned and matched to form a complete forming cavity. At the same time, after closing, the cold air channels inside the two are connected to cool and lower the temperature of the pulley during forming.

[0033] Through the indexing mechanism, the four-jaw chuck and the lower die are driven to rotate to each station, so as to promote a series of production links such as pouring, closing, cooling and forming, and opening the die to take out the finished product. At the same time, the indexing mechanism is cooperated with the air distributor to ensure stable connection when the indexing mechanism rotates and avoid cold air leakage.

[0034] Through the cooperation of the cooling fan, the air distributor, the lower die and the upper die, the cooling and forming of the molten material in the die are realized.

[0035] Through the cooperation of the cooling fan, the cooling mechanism and the conveyor, the cooling of the pulley finished product on the conveyor is realized, which is convenient for subsequent handling.

[0036] Through the cooperation of the upper die manipulator and the finished product manipulator with the moving guide rail mechanism respectively, the moving guide rail mechanism drives the upper die manipulator to grasp the upper die for closing and transfer operations, and the moving guide rail mechanism drives the finished product manipulator to take out the formed pulley and place it on the subsequent conveyor.

[0046] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0047] As Figures 1-8As shown in the figure, the forming device for intelligent processing of this pulley includes a melting furnace, several upper molds 11, and a indexing mechanism 4, a moving guide rail mechanism 5, and a conveyor 9 arranged in sequence from front to back. A wind distributor 3 is provided in the middle of the indexing mechanism 4. The space at the upper end of the indexing mechanism 4 is divided into a finished product picking area, a pouring area, a mold closing area, and several cooling areas. The finished product picking area, the pouring area, the mold closing area, and several cooling areas are arranged in a circumferential uniform distribution. Four-jaw chucks 2 are provided on the finished product picking area, the pouring area, the mold closing area, and several cooling areas. Lower molds 1 are provided on the four-jaw chucks 2. An upper mold manipulator 6 and a finished product manipulator 8 are driven on the moving guide rail mechanism 5. The upper mold manipulator 6 is located directly above the finished product picking area and the mold closing area. The finished product manipulator 8 is located directly above the conveyor 9 and the finished product picking area. The pouring area is located directly in front of the melting furnace. The melting furnace is located directly behind the moving guide rail mechanism 5. A chuck power mechanism 7 and a cooling mechanism 10 are provided on the conveyor 9. Upper molds 11 are placed above the lower molds 1 in the cooling areas. The finished product picking area is located directly in front of the chuck power mechanism 7. The wind distributor 3 and the lower mold 1 are connected by pipelines. A first cold air channel is provided inside the lower mold 1. A second cold air channel is provided inside the upper mold 11. After the upper mold 11 and the lower mold 1 are closed, the first cold air channel and the second cold air channel are connected. Both the wind distributor 3 and the cooling mechanism 10 are connected to a cold air blower through pipelines.

[0048] In this embodiment, the molten material in the melting furnace is injected into the cavity of the lower mold 1 in the pouring area. After pouring is completed, at this time, the operations on each work station are all completed. The indexing mechanism 4 rotates intermittently, and the lower mold 1 filled with material is rotated to the next work station. After reaching the mold closing area, the upper mold manipulator 6 moves the upper mold 11 to the upper part of the lower mold 1 in the mold closing area for mold closing. After mold closing is completed, the upper mold manipulator 6 returns to the finished product picking area. At this time, the indexing mechanism 4 rotates again, and the closed mold is rotated to the cooling area. The cold air blower delivers cold air to the wind distributor 3. The wind distributor 3 delivers the cold air to the first cold air channel inside the lower mold 1, then enters the second cold air channel inside the upper mold 11, and finally discharges, cooling the molten material in the mold and accelerating the forming of the pulley.

[0049] When the cooling process ends, the indexing mechanism 4 rotates the cooled mold to the finished product picking area. The upper mold manipulator 6 moves downward to grasp the upper mold 11. After grasping, the upper mold manipulator 6 moves upward and moves to the mold closing area. At this time, the finished product manipulator 8 moves to the finished product picking area. The chuck power mechanism 7 controls the four-jaw chuck 2 to open, driving the lower mold 1 to open the mold. The finished product manipulator 8 moves downward, takes out the formed pulley from the mold, and places it on the conveyor 9. The chuck power mechanism 7 then controls the four-jaw chuck 2 to clamp, so that the four-jaw chuck 2 drives the lower mold 1 to close the mold again. At this time, the pouring of the lower mold 1 in the pouring area is completed. The indexing mechanism 4 rotates again, rotating the closed lower mold 1 to the pouring area, repeating the above process. At the same time, the cold air blower conveys cold air to the cooling mechanism 10, and the cooling mechanism 10 performs secondary cooling on the pulley on the conveyor 9 to ensure that it reaches the temperature and performance required by the process.

[0050] The indexing mechanism 4 includes a base. At the upper end of the base, there is a cam divider 20. At the upper end of the output shaft of the cam divider 20, there is an indexing tray 19. The space at the upper end of the indexing tray 19 is divided into a finished product picking area, a pouring area, a mold closing area, and several cooling areas. The finished product picking area, the pouring area, the mold closing area, and several cooling areas are arranged in a circumferential and equally spaced manner. The four-jaw chuck 2 is fixed above the indexing tray 19. At the lower end of the indexing tray 19, there are several circumferentially and equally spaced universal wheel rods 21. The positions and quantities of the universal wheel rods 21 correspond to those of the four-jaw chuck 2. At the lower ends of the universal wheel rods 21, there are universal wheels 18.

[0051] In this embodiment, the output shaft of the cam divider 20 drives the upper indexing tray 19 to rotate intermittently. The indexing tray 19 drives the upper four-jaw chuck 2 and the lower mold 1 to sequentially pass through the finished product picking area, the pouring area, the mold closing area, and several cooling areas. The universal wheel rods 21 and the universal wheels 18 play a supporting role and flexibly move to the appropriate positions following the indexing tray 19.

[0052] The air distributor 3 includes an air distributor body 23. The air distributor body 23 is arranged at the center of the indexing tray 19. Below the air distributor body 23, there is a main pipe 25 connected to it. The main pipe 25 passes through the cam divider 20. Below the main pipe 25, there is a rotary joint 26. The rotary joint 26 is connected to the air outlet of the cold air blower through a pipe. At the upper end of the main pipe 25, there are branch air pipes 24 connected to several circumferentially and equally spaced ones.

[0053] In this embodiment, the cold air blown out by the cold air blower enters the main pipe 25 through the rotary joint 26, reaches the air distributor body 23, and the cold air entering the air distributor body 23 is evenly distributed in all directions, reaches each branch air pipe 24, and the cold air is conveyed to the lower mold 1 through pipe connection.

[0054] The lower die 1 includes a bottom die 13 and four side dies 12 evenly distributed in a circle. The bottom die 13 is fixed to the upper end of the four-jaw chuck 2, and the side dies 12 are arranged at the upper ends of the corresponding jaws 22 of the four-jaw chuck 2. Positioning columns 15 are fixed to the upper ends of three of the side dies 12. Cold air sub-channels are provided inside the four side dies 12. After the four side dies 12 are closed, the four cold air sub-channels are connected to form a first cold air channel. Above another side die 12, there is a side die air outlet joint 14 connected to the cold air sub-channel inside it. On the side of a side die 12 adjacent to the side die 12 provided with the side die air outlet joint 14, there is a side die air inlet joint 16 connected to the cold air sub-channel inside it. The branch air duct 24 is connected to the corresponding side die air inlet joint 16 through a flexible pipe.

[0055] In this embodiment, the positioning columns 15 are used for accurately positioning the upper die 11. The jaws 22 of the four-jaw chuck 2 drive the side dies 12 to move, controlling the closing or opening of the side dies 12. The side dies 12, the bottom die 13 and the upper die 11 are closed to form a closed cavity. Cold air enters the side dies 12 through the side die air inlet joint 16 via the branch air duct 24, flows in the first cold air channel, cools the pulley during the forming process, and the cold air reaches the upper die 11 from the side die air outlet joint 14. By controlling the inflow and outflow of cold air, the forming temperature is adjusted.

[0056] The upper die 11 includes an upper die main body 27. The upper die main body 27 is located above the lower die 1. A second cold air channel is provided inside the upper die main body 27. Below the upper die main body 27, there is an upper die air inlet hole 29 matching the side die air outlet joint 14. Three positioning holes 28 matching the positioning columns 15 are fixed below the upper die main body 27. The side die air outlet joint 14 is inserted into the corresponding upper die air inlet hole 29 inside. The upper die air inlet hole 29 is connected to the second cold air channel. A counterweight 31 is fixed above the upper die main body 27. There is an upper die air outlet joint 30 connected to the second cold air channel inside it on the side of the upper die main body 27.

[0057] In this embodiment, the positioning holes 28 cooperate with the positioning columns 15 to achieve precise positioning. Cold air enters the upper die air inlet hole 29 from the side die air outlet joint 14, flows in the second cold air channel, cools the pulley during the forming process, and finally the hot air is discharged from the upper die air outlet joint 30 for other uses. The pulley in the die is cooled in the closed die state. The counterweight 31 above the upper die main body 27 increases the weight of the upper die 11, ensuring the stability and tightness of the closed die.

[0058] The moving guide rail mechanism 5 includes a moving guide rail frame 32. The moving guide rail frame 32 is in an inverted U shape. Two guide rods 33 and a lead screw 34 are fixed on the moving guide rail frame 32. The two guide rods 33 are located on both sides of the lead screw 34.

[0059] In this embodiment, the moving guide rail frame 32 provides support, and the upper die manipulator 6 and the finished product manipulator 8 move on the lead screw 34 and the two guide rods 33.

[0060] The upper die manipulator 6 includes a second moving block 40. The second moving block 40 is slidably arranged on the two guide rods 33. A second lead screw motor 41 is fixed below the second moving block 40. A second screw joint seat 51 is arranged on the second moving block 40. A transmission connection is provided between the driving shaft of the second lead screw motor 41 and the second screw joint seat 51. A transmission connection is provided between the lead screw 34 and the second screw joint seat 51. A second lifting hydraulic cylinder 36 is arranged in front of the second moving block 40. A second mechanical claw is arranged on the telescopic end of the second lifting hydraulic cylinder 36.

[0061] In this embodiment, the driving shaft of the second lead screw motor 41 drives the second screw joint seat 51 to rotate. The second screw joint seat 51 is in transmission connection with the lead screw 34, so that the second moving block 40 moves on the lead screw 34. After moving to the specified position, the second lifting hydraulic cylinder 36 works, and its telescopic end drives the second mechanical claw to move up and down. The second mechanical claw opens or closes to complete the grasping or releasing action of the upper die 11, thereby completing the picking and placing operation of the upper die 11.

[0063] In this embodiment, the driving shaft of the first lead screw motor 38 drives the first screw joint seat 50 to rotate. The first screw joint seat 50 is in transmission connection with the lead screw 34, so that the first moving block 39 slides horizontally on the lead screw 34. After moving to the specified position, the first lifting hydraulic cylinder 35 works, and its telescopic end drives the first mechanical claw 37 to move up and down. The first mechanical claw 37 opens or closes to complete the grasping or releasing action of the finished product, and the feeding and discharging operations are completed.

[0064] The chuck power mechanism 7 includes a power machine frame 44. The power machine frame 44 is fixed on the machine frame of the conveyor 9. A moving electric push rod 42 is fixed on the power machine frame 44. A moving seat 46 is slidably arranged on the power machine frame 44. The moving seat 46 is fixedly connected to the telescopic end of the moving electric push rod 42. Two groups of symmetrically arranged limit sensors 43 are fixed on the power machine frame 44. The two groups of limit sensors 43 are located on both sides of the moving seat 46. A rotating motor is fixed on the moving seat 46. A power connecting rod 45 is fixed on the output shaft of the rotating motor. The power connecting rod 45 faces the adjusting gear rod 17 of the four-jaw chuck 2 at the corresponding position.

[0065] In this embodiment, the telescopic end of the mobile electric push rod 42 drives the mobile seat 46 to move on the power frame 44, thereby driving the rotation motor and the power connecting rod 45 to move. Two groups of limit sensors 43 are used to limit the moving range of the mobile seat 46. The power connecting rod 45 is inserted into the adjusting gear rod 17 of the four-jaw chuck 2 at the corresponding position. The rotation motor drives the power connecting rod 45 to rotate, thereby driving the jaws 22 to clamp or open, for the side mold 12 to be closed or opened.

[0066] The cooling mechanism 10 includes a cooling box 48. The cooling box 48 is arranged above the conveyor 9. Wind shielding curtains 49 are arranged at both openings on both sides of the cooling box 48. A cooling box air inlet joint 47 is arranged on the side of the cooling box 48. The cooling box air inlet joint 47 is connected to the air outlet of the cold air blower through a pipeline.

[0067] In this embodiment, the cold air generated by the cold air blower enters the cooling box 48 through the pipeline from the cooling box air inlet joint 47. When the finished belt pulley on the conveyor 9 is conveyed into the cooling box 48, the cold air in the cooling box 48 cools it. The wind shielding curtain 49 can reduce the leakage of cold air and ensure a good cooling environment in the cooling box 48.

[0068] The working principle of the present invention: Inject the molten material in the melting furnace into the cavity of the lower mold 1 located in the pouring area. After pouring is completed, at this time, the operations at each station are all completed. The output shaft of the cam divider 20 drives the upper indexing tray 19 to rotate intermittently, rotates the lower mold 1 with the injection completed 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 following the indexing tray 19;

[0069] After reaching the mold closing area, the moving guide rail frame 32 provides support. The driving shaft of the screw motor two 41 drives the screw joint two 51 to rotate. The screw joint two 51 is in transmission connection with the screw rod 34, so that the moving block two 40 moves on the screw rod 34, moves the upper mold 11 to above the lower mold 1 in the mold closing area. The telescopic end of the lifting hydraulic cylinder two 36 drives the mechanical jaw two to move downward. The mechanical jaw two 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 picking area;

[0070] The output shaft of the cam divider 20 drives the indexing tray 19 at the upper end to rotate intermittently again, rotating the mold after mold closing to the cooling area. The cold air blown by the cold air blower enters the main pipe 25 through the rotating joint 26, reaches the air distributor body 23, and the cold air entering the air distributor body 23 is evenly distributed in 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 first cold air passage, and then enters the upper mold air inlet hole 29 through the side mold air outlet joint 14, flows in the second cold air passage, cools the pulley during the molding process, and finally the hot air is discharged from the upper mold air outlet joint 30 for other uses, cools the molten material in the mold, accelerates the pulley molding. The counterweight 31 above the upper mold body 27 increases the weight of the upper mold 11, ensuring the stability and tightness of mold closing;

[0071] When the cooling process ends, the output shaft of the cam divider 20 drives the indexing tray 19 at the upper end to rotate the cooled mold to the finished product picking area. The moving guide rail frame 32 provides support. The lifting hydraulic cylinder II 36 works, and its telescopic end drives the mechanical gripper II to move downward. The mechanical gripper II opens to complete the grasping action of the upper mold 11, thus completing the grasping operation of the upper mold 11. After grasping, the lifting hydraulic cylinder II 36 works, and its telescopic end drives the mechanical gripper II to move upward. The driving shaft of the screw motor II 41 drives the screw joint II 51 to rotate. The screw joint II 51 is in transmission connection with the screw rod 34, so that the moving block II 40 moves on the screw rod 34 and moves to the mold closing area. At this time, the driving shaft of the screw motor I 38 drives the screw joint I 50 to rotate. The screw joint I 50 is in transmission connection with the screw rod 34, so that the moving block I 39 slides horizontally on the screw rod 34. The finished product manipulator 8 moves to the finished product picking area. The telescopic end of the moving electric push rod 42 drives the moving seat 46 to move on the power frame 44, thus driving the rotating motor and the power connecting rod 45 to move. Two groups 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-jaw chuck 2 at the corresponding position. The rotating motor drives the power connecting rod 45 to rotate clockwise, thus driving the jaws 22 to open for the side mold 12 to open the mold. The lifting hydraulic cylinder I 35 works, and its telescopic end drives the mechanical gripper I 37 to move downward. The mechanical gripper I 37 opens to complete the grasping action of the finished product, takes out the molded pulley from the mold, and places it on the conveyor 9. The telescopic end of the moving electric push rod 42 drives the moving seat 46 to move on the power frame 44, thus driving the rotating motor and the power connecting rod 45 to move. Two groups 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-jaw chuck 2 at the corresponding position. The rotating motor drives the power connecting rod 45 to rotate counterclockwise, thus driving the jaws 22 to clamp, so that the jaws 22 drive the side mold 12 to close the mold again;

[0072] At this time, the pouring of the lower mold 1 in the pouring area is completed. The output shaft of the cam divider 20 drives the indexing tray 19 at the upper end to rotate again, rotating the closed lower mold 1 to the pouring area and repeating the above process. At the same time, the cold air generated by the cold air blower enters the cooling box 48 through the air inlet joint 47 of the cooling box via a pipeline. When the finished pulley on the conveyor 9 is conveyed into the interior of the cooling box 48, the cold air in the cooling box 48 cools it down a second time. The windproof curtain 49 can reduce the leakage of cold air, ensuring a good cooling environment in the cooling box 48 and ensuring that it reaches the temperature and performance requirements of the process.

[0073] In summary, through the cooperation of the lower mold 1, the four-jaw chuck 2 and the chuck power mechanism 7, the closing of the lower mold 1 is controlled, facilitating pouring, or the opening of the lower mold 1 is controlled to take out the finished pulley.

[0074] Through the cooperation of the lower mold 1 and the upper mold 11, when closing the mold, the two are accurately positioned and matched to form a complete molding cavity. At the same time, after closing the mold, the cold air channels inside the two are connected to cool down the pulley during molding.

[0075] Through the indexing mechanism 4, the four-jaw chuck 2 and the lower mold 1 are driven to rotate to each station, thus promoting a series of production links such as pouring, closing the mold, cooling and forming, and opening the mold to take the finished product. At the same time, the indexing mechanism 4 cooperates with the air distributor 3 to ensure stable connection when the indexing mechanism 4 rotates and avoid cold air leakage.

[0076] Through the cooperation of the cold air blower, the air distributor 3, the lower mold 1 and the upper mold 11, the cooling and forming of the molten material in the mold are realized.

[0077] Through the cooperation of the cold air blower, the cooling mechanism 10 and the conveyor 9, the cooling of the pulley finished products on the conveyor 9 is realized, facilitating subsequent handling.

[0078] Through the cooperation of the upper mold manipulator 6 and the finished product manipulator 8 with the moving guide rail mechanism 5 respectively, the moving guide rail mechanism 5 drives the upper mold manipulator 6 to grasp the upper mold 11 for mold closing and transfer operations, and the moving guide rail mechanism 5 drives the finished product manipulator 8 to take out the formed pulley and place it on the subsequent conveyor 9.

Those skilled in the technical field to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
