Description

Technical Field

[0001] The invention relates to the technical field of stamping and forming, in particular to a parts stamping and forming machine for producing automobile fan motors. Background Art

[0002] The automobile fan motor is a key component in the automobile cooling system. Its main function is to drive the fan to rotate, so that air flows and helps the engine, radiator and other components to dissipate heat. Most automobile fan motors are DC motors. When current passes through the stator winding of the motor, a magnetic field is generated. The rotor (usually composed of an iron core and a winding, or a permanent magnet) is subjected to the Ampere force under the action of the magnetic field and begins to rotate. Taking the permanent magnet DC motor as an example, its stator is a permanent magnet that produces a fixed magnetic field. After current is passed through the rotor winding, according to the left-hand rule, the rotor will be subjected to a force that makes it rotate. The speed of the motor can usually be controlled by changing the input voltage or current, thereby adjusting the speed of the fan to meet different heat dissipation requirements.

[0003] When stamping automotive fan motor parts, long-term stamping work will cause the mold to heat up and then cause thermal expansion of the mold. High temperature may reduce the hardness of the mold surface, causing the mold to wear more during the stamping process. When the mold is worn, scratches, burrs and other defects will appear on the surface of the stamped parts. Summary of the invention

The top of the guide rod is fixedly connected to a top plate, and the top of the top plate is fixedly connected to a hydraulic cylinder. The side of the guide rod is slidably connected to an upper die seat, and the bottom of the upper die seat is fixedly connected to an upper module, and the top of the upper die seat is fixedly connected to the output end of the hydraulic cylinder; when the conveying device conveys the sheet to the lower die seat and places the sheet on the lower module, the hydraulic cylinder is turned on and the upper die seat is driven by the output end of the hydraulic cylinder to move downward on the guide rod, so that the upper die seat drives the upper module to move the lower die seat and the lower module, thereby performing stamping and forming work on the raw material sheet. After the stamping is completed, the upper die seat drives the upper module to move upward. At this time, the stamped parts need to be smoothly demolded from the mold, and the parts can be ejected from the lower module by the action of an ejection device such as an ejector pin or an ejector; The cooling component comprises a water tank, the bottom of the water tank is fixedly connected to the bottom of the inner cavity of the base, the top of the water tank is fixedly connected to the bottom of the lower die seat, a pressure pump is fixedly connected to the bottom of the inner cavity of the water tank, a water inlet pipe is fixedly connected to the side of the water tank, one end of the water inlet pipe away from the water tank is fixedly connected to the inner side of the cooling groove, one end of the water inlet pipe close to the water tank is fixedly connected to a one-way valve, a side of the water tank away from the water inlet pipe is fixedly connected to a water outlet mechanism, and the other end of the water outlet mechanism is fixedly connected to the inner side of the cooling groove; when performing stamping work, by turning on the pressure pump, the water in the water tank enters the cooling groove through the water outlet mechanism, and by the continuous operation of the pressure pump, the water flow continues to move in the cooling groove until it enters the water tank through the water inlet pipe, and continuous water circulation work is performed. When performing stamping work, the temperature of the surface of the lower die seat can be cooled down by the circulating flow of water, thereby avoiding that when the stamping work is performed for a long time, the high temperature may reduce the hardness of the mold surface, resulting in increased wear of the mold during the stamping process; The top of the water outlet pipe is fixedly connected with the inner side of the cooling tank, the top of the inner side of the water outlet pipe is fixedly connected with a bracket, the bottom of the bracket is fixedly connected with a connecting shaft, and the other end of the connecting shaft is slidably connected with a moving assembly.

If the scale layer becomes thicker, it will cause the effective internal The diameter becomes smaller, so that the speed of water flowing through the water inlet pipe becomes slower. Since the water contains various microorganisms, such as bacteria, algae, etc., when the water flows in the water inlet pipe, these microorganisms will adhere to the inner wall of the water inlet pipe. When the water flows continuously through the water inlet pipe, the water flow continuously impacts the movable frame, so that the water flow drives the movable frame to move on the connecting shaft, and at the same time squeezes the first spring, so that the movable frame drives the scraper to clean the inner wall of the outlet pipe through the movable plate. When the stamping work is completed and the pressure pump stops working, the squeezing work of the water flow on the first spring disappears, and the first spring performs reset stretching movement, so that the first spring drives the movable frame to reset and move on the connecting shaft, so that the movable frame drives the scraper to perform secondary cleaning movement on the outlet pipe through the movable plate, and the scraper and the movable component are continuously in contact and moved, so that the movable component is separated from the outlet pipe, and the impurities that fall from the outlet pipe cleaned by the scraper flow out of the outlet pipe; Preferably, the moving assembly comprises a mesh plate and a sliding groove, the side surface of the mesh plate is slidably connected to the inner side of the water outlet pipe, the sliding groove is evenly opened on the inner wall of the water outlet pipe, the mesh plate is fixedly connected to a connecting rod on the side close to the water outlet pipe, the number of the connecting rods is three, and the three connecting rods are evenly arranged with the circular plate as the center, the side surface of the connecting rod is fixedly connected to the circular plate, the side of the circular plate away from the mesh plate is fixedly connected to the sliding rod, one end of the sliding rod away from the circular plate is slidably connected to the inner side of the connecting shaft, a second spring is sleeved on the sliding rod, one end of the second spring is fixedly connected to the circular plate, and the other end of the second spring is fixedly connected to the connecting shaft, the end of the connecting rod away from the mesh plate is fixedly connected to a sliding frame, the inner side of the sliding frame is slidably connected to the side surface of the connecting shaft, the side surface of the sliding frame is fixedly connected to a slider, and the side surface of the slider is slidably connected to the inner side of the sliding groove; When the stamping work is completed and the pressure pump stops working, the squeezing work of the water flow on the first spring disappears, and the first spring performs a reset stretching movement, so that the first spring drives the moving frame to perform a reset movement work on the connecting shaft, and the scraper and the sliding frame perform continuous contact and squeezing, so that the sliding frame passes through the slider to slide in the sliding groove, and at the same time, the sliding frame drives the circular plate and the mesh plate to separate from the water inlet pipe through the connecting rod, so that the scraper cleans the impurities that fall from the water outlet pipe and can flow into the water outlet pipe. At the same time, when the water flow in the water tank continues to enter the water outlet pipe driven by the pressure pump, the water flow squeezes and impacts the mesh plate. When the mesh plate is subjected to the impact force of the water flow, the mesh plate drives the circular plate through the connecting rod, so that the circular plate drives the sliding rod to slide on the connecting shaft, and at the same time squeezes the second spring in the stretched state, so that the mesh plate filters the impurities in the water flow; Preferably, the collecting component includes a collecting box and a collecting trough, the collecting trough is symmetrically opened on the inner side of the lower die base, the collecting trough is arranged above the lower module, the side of the collecting box is fixedly connected to the inner side of the base, the inner side of the collecting trough is fixedly connected with a feed plate, the bottom of the collecting trough is fixedly connected with a connecting sleeve, the bottom of the connecting sleeve is fixedly connected to the inner side of the collecting box, the inner side of the collecting box is fixedly connected with a suction mechanism, the inner side of the collecting box close to the suction mechanism is fixedly connected with a baffle, and the inner side of the collecting box is evenly provided with a rotating mechanism; after the stamping and forming parts are stripped, the suction mechanism is turned on and the suction force generated by the suction mechanism when the suction mechanism is working is used to suck the lower die base Extraction and cleaning work is carried out in the mold to prevent metal chips from remaining on the working surface of the mold, which will affect the surface quality of the stamped parts. In the subsequent stamping process, metal chips may be pressed into the surface of the new stamped parts, forming scratches, pits and other defects. For parts with high precision requirements such as the rotor shaft of the automobile fan motor, these defects may cause the assembly accuracy of the parts with matching parts such as bearings to decrease, increase friction and wear, and affect the performance of the motor, thereby causing metal impurities to enter the collection tank through the baffle, and then enter the collection box through the connecting sleeve for collection. At the same time, when the external dust enters the collection box together, the rotating mechanism grabs the dust that follows the metal impurities into the collection box; Preferably, the rotating mechanism includes a rotating shaft, and the upper and lower ends of the rotating shaft are rotatably connected to rotating plates, and the side of the rotating plate away from the rotating shaft is rotatably connected to the inner side of the collecting box, and the side of the rotating shaft is fixedly connected to a grabbing rod, and the number of the grabbing rods is six, and the six grabbing rods are cross-arranged in sequence, and the middle part of the side of the grabbing rod is fixedly connected to a grabbing block; when the external dust follows the metal impurities in the lower mold base and enters the collecting box together, when the dust passes through the rotating shaft, the grabbing rods and grabbing blocks are evenly arranged on the side of the rotating shaft, so that the flocculent dust entering the collecting box can be grabbed and entangled, thereby avoiding the metal impurities entering the collecting box and the flocculent dust from being entangled and aggregated in the inner cavity of the collecting box, thereby interfering with the ventilation effect of the connecting sleeve.

[0005] The present invention provides a parts stamping machine for automobile fan motor production, which has the following beneficial effects: 1. A stamping machine for producing parts for automobile fan motors is provided with a cooling component. When performing stamping work, the pressure pump is turned on so that the water in the water tank enters the cooling tank through the water outlet mechanism. The pressure pump continues to work so that the water continues to move in the cooling tank until it enters the water tank through the water inlet pipe, and continuous water circulation is performed. When performing stamping work, the temperature of the surface of the lower die seat can be cooled by the circulation of water, thereby avoiding the high temperature that may reduce the hardness of the die surface during long-term stamping work, resulting in increased wear of the die during the stamping process.

[0006] 2. This kind of automobile fan motor production parts stamping forming machine is provided with a water outlet mechanism. The water in the water tank continuously flows through the water outlet pipe into the cooling tank to avoid that when the water flows continuously through the water outlet pipe into the cooling tank, a large amount of scale will remain on the inner wall of the water outlet pipe. If the scale layer becomes thicker, the effective inner diameter of the water inlet pipe will become smaller, so that the speed of water flowing through the water inlet pipe will slow down. Since the water contains various microorganisms, such as bacteria, algae, etc., when the water flows in the water inlet pipe, these microorganisms will adhere to the inner wall of the water inlet pipe. When the water flows continuously through the water inlet pipe, the water flow continuously impacts the mobile frame, thereby making the water flow The movable frame is driven to move on the connecting shaft, and the first spring is squeezed at the same time, so that the movable frame drives the scraper to clean the inner wall of the water outlet pipe through the movable plate. When the stamping work is completed and the pressure pump stops working, the squeezing work of the water flow on the first spring disappears, and the first spring performs a reset and stretching movement, so that the first spring drives the movable frame to reset and move on the connecting shaft, so that the movable frame drives the scraper to perform a secondary cleaning movement on the water outlet pipe through the movable plate, and the scraper and the movable component are continuously in contact and moved, so that the movable component is separated from the water outlet pipe, and the impurities that have been cleaned off the water outlet pipe by the scraper flow out of the water outlet pipe.

When the stamping work is completed and the pressure pump stops working, the squeezing work of the water flow on the first spring disappears, and the first spring performs a reset stretching movement, so that the first spring drives the moving frame to perform a reset movement on the connecting shaft, and the scraper and the sliding frame are continuously contacted and squeezed, so that the sliding frame passes through the slider and slides in the sliding groove. At the same time, the sliding frame drives the circular plate and the mesh plate to separate from the water inlet pipe through the connecting rod, so that the scraper cleans the impurities that fall from the outlet pipe and can flow into the outlet pipe. At the same time, when the water flow in the water tank continues to enter the outlet pipe driven by the pressure pump, the water flow squeezes and impacts the mesh plate. When the mesh plate is subjected to the impact force of the water flow, the mesh plate drives the circular plate through the connecting rod, so that the circular plate drives the sliding rod to slide on the connecting shaft, and at the same time squeezes the second spring in the stretched state, so that the mesh plate filters the impurities in the water flow.

[0008] 4. This kind of automobile fan motor parts stamping and forming machine is provided with a collecting component. After the stamped and formed parts are stripped, the suction mechanism is turned on and the suction force generated by the suction mechanism is used to extract and clean the lower die seat, thereby avoiding metal chips from remaining on the working surface of the mold, which will affect the surface quality of the stamped parts. In the subsequent stamping process, the metal chips may be pressed into the surface of the new stamped parts, forming scratches, pits and other defects. For parts with high precision requirements such as the rotor shaft of the automobile fan motor, these defects may cause the assembly accuracy with matching parts such as bearings to decrease, increase friction and wear, and affect the performance of the motor, thereby allowing the metal impurities to enter the collection groove through the baffle, and then enter the collection box through the connecting sleeve for collection. At the same time, when the external dust enters the collection box together, the rotating mechanism can capture the dust that enters the collection box following the metal impurities.

After the stamping is completed, the upper die base 15 drives the upper die block 16 to move upward. At this time, the stamped parts need to be smoothly demolded from the mold, and the parts can be ejected from the lower die block 17 by the action of an ejection device such as an ejector pin or an ejector.

A grabbing block 374 is fixedly connected to the middle of the side of the grabbing rod 373; when the external dust follows the metal impurities in the lower mold base 11 and enters the collecting box 31 together, when the dust passes through the rotating shaft 371, the grabbing rods 373 and the grabbing blocks 374 are evenly arranged on the side of the rotating shaft 371, so that the flocculent dust entering the collecting box 31 can be grabbed and entangled, thereby avoiding the metal impurities and flocculent dust entering the collecting box 31 from being entangled and gathered in the inner cavity of the collecting box 31, thereby interfering with the ventilation effect of the connecting sleeve 34.

[0013] Specific workflow: The raw materials used for stamping of automobile fan motor parts are mainly metal plates, such as cold-rolled steel plates, silicon steel sheets, etc. Cold-rolled steel plates have good surface quality and dimensional accuracy, and are suitable for manufacturing parts such as motor housings. After pre-treatment, the raw materials are transported to the working area of ​​the stamping component 1 through a feeding device. When the raw materials are transported to the bottom of the stamping component 1, the stamping component 1 punches the plate into the required shape. At the same time, when the stamping component 1 is stamping, the stamping component 1 can be cooled by the cooling component 4. At the same time, after the stamped plate in the stamping component 1 is taken out, the plate debris in the stamping component 1 can be collected and processed by the collecting component 3; When the conveying device conveys the sheet to the lower die base 11 and places the sheet on the lower die block 17, the hydraulic cylinder 14 is turned on and the upper die base 15 is driven by the output end of the hydraulic cylinder 14 to move downward on the guide rod 12, so that the upper die base 15 drives the upper die block 16 to move toward the lower die base 11 and the lower die block 17, thereby performing stamping and forming work on the raw material sheet. After the stamping is completed, the upper die base 15 drives the upper die block 16 to move upward. At this time, the stamped parts need to be smoothly demolded from the mold, and the parts can be ejected from the lower die block 17 by the action of an ejection device such as an ejector pin or an ejector. When performing stamping, the pressure pump 42 is turned on, so that the water in the water tank 41 enters the cooling groove 18 through the water outlet mechanism 45. The pressure pump 42 continues to work, so that the water continues to move in the cooling groove 18 until it enters the water tank 41 through the water inlet pipe 43, and continuous water circulation is performed. When performing stamping, the surface temperature of the lower die seat 11 can be cooled by the circulation of water, thereby avoiding the high temperature that may reduce the hardness of the die surface during long-term stamping, resulting in increased wear of the die during the stamping process. The water in the water tank 41 continuously flows through the water outlet pipe 451 into the cooling tank 18, so as to avoid a large amount of scale remaining on the inner wall of the water outlet pipe 451 when the water flows continuously through the water outlet pipe 451 into the cooling tank 18. If the scale layer becomes thicker, the effective inner diameter of the water inlet pipe 43 will become smaller, so that the speed of the water flowing through the water inlet pipe 43 will become slower. Since the water contains various microorganisms, such as bacteria, algae, etc., when the water flows in the water inlet pipe 43, these microorganisms will adhere to the inner wall of the water inlet pipe 43. When the water flows continuously through the water inlet pipe 43, the moving frame 455 is continuously impacted by the water flow, so that the water flow drives the moving frame 455 to move on the connecting shaft 453, and at the same time squeezes the first spring 454, thereby The movable frame 455 drives the scraper 458 to clean the inner wall of the water outlet pipe 451 through the movable plate 456. When the stamping work is completed and the pressure pump 42 stops working, the squeezing work of the water flow on the first spring 454 disappears, and the first spring 454 performs a reset stretching movement, so that the first spring 454 drives the movable frame 455 to perform a reset movement on the connecting shaft 453, so that the movable frame 455 drives the scraper 458 to perform a secondary cleaning movement on the water outlet pipe 451 through the movable plate 456, and the scraper 458 and the movable component 459 are continuously in contact and moved, so that the movable component 459 is separated from the water outlet pipe 451, and the impurities that have been cleaned off the water outlet pipe 451 by the scraper 458 flow out of the water outlet pipe 451; When the stamping work is completed and the pressure pump 42 stops working, the squeezing work of the water flow on the first spring 454 disappears, and the first spring 454 performs a reset stretching movement, so that the first spring 454 drives the moving frame 455 to perform a reset movement work on the connecting shaft 453, and the scraper 458 and the sliding frame 4597 are continuously contacted and squeezed, so that the sliding frame 4597 slides in the sliding groove 4592 through the slider 4598, and at the same time, the sliding frame 4597 drives the circular plate 4594 and the mesh plate 4591 to separate from the water inlet pipe 43 through the connecting rod 4593, so that the scraper 458 The impurities dropped from the water outlet pipe 451 can flow into the water outlet pipe 451. Meanwhile, when the water flow in the water tank 41 continuously enters the water outlet pipe 451 driven by the pressure pump 42, the water flow squeezes and impacts the mesh plate 4591. When the mesh plate 4591 is impacted by the water flow, the mesh plate 4591 drives the circular plate 4594 through the connecting rod 4593, so that the circular plate 4594 drives the sliding rod 4595 to slide on the connecting shaft 453, and at the same time squeezes the second spring 4596 in a stretched state, so that the mesh plate 4591 filters the impurities in the water flow. After the stamped parts are stripped, the suction mechanism 35 is turned on and the suction force generated by the suction mechanism 35 is used to extract and clean the lower die seat 11, thereby preventing metal chips from remaining on the working surface of the mold, which will affect the surface quality of the stamped parts. In the subsequent stamping process, the metal chips may be pressed into the surface of the new stamped parts, forming scratches, pits and other defects. For parts with high precision requirements such as the rotor shaft of the automobile fan motor, these defects may cause the assembly accuracy with the matching parts such as bearings to decrease, increase friction and wear, and affect the performance of the motor, so that the metal impurities enter the collection groove 32 through the baffle 36, and then enter the collection box 31 through the connecting sleeve 34 for collection. At the same time, when the external dust enters the collection box 31 together, the rotating mechanism 37 grabs the dust that follows the metal impurities into the collection box 31; When external dust enters the collection box 31 together with the metal impurities in the lower mold base 11, when the dust passes through the rotating shaft 371, the grabbing rods 373 and the grabbing blocks 374 are evenly arranged on the side of the rotating shaft 371, so that the flocculent dust entering the collection box 31 can be grabbed and entangled, thereby avoiding the metal impurities and flocculent dust entering the collection box 31 from being entangled and gathered in the inner cavity of the collection box 31, thereby interfering with the ventilation effect of the connecting sleeve 34.
