Description

Technical Field

[0001] The invention relates to the technical field of dies, in particular to a bearing ring forging die. Background Art

[0002] The bearing ring is an annular part of a radial rolling bearing with one or more raceways. It is a tool that makes the blank into a product with a specific shape and size under the action of external force. It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy pressing, pressure casting, and compression or injection molding of engineering plastics, rubber, ceramics and other products. The mold has a specific contour or inner cavity shape. The use of a contour shape with a cutting edge can make the blank separate (punch out) according to the shape of the contour line. The use of the inner cavity shape can make the blank obtain a corresponding three-dimensional shape. The mold generally includes a movable mold and a fixed mold (or a punch and a die), which can be separated or combined. When separated, the product is taken out, and when closed, the blank is injected into the mold cavity for forming. The mold is a precision tool with a complex shape. It bears the expansion force of the blank. It has high requirements for structural strength, rigidity, surface hardness, surface roughness and processing accuracy. The development level of mold production is one of the important indicators of the level of mechanical manufacturing.

[0003] Although traditional bearing ring molds can achieve automated production, they still have the following shortcomings:

[0004] 1. When forging traditional bearing ring dies, a robot is required to complete the transfer of stamped castings, which has a complex structure and high cost.

[0005] 2. When the traditional bearing ring mold is forging, the stamping casting will drop iron chips on the die. There is a lack of automatic cleaning mechanism to clean the iron chips on the die. If it is not cleaned for a long time, it will affect the quality of the stamping parts and increase the defective rate.

[0006] Therefore, a bearing ring forging die is proposed. Summary of the invention

[0007] The object of the present invention is to provide a bearing ring forging die, which can automatically load and unload materials and clean the die base by arranging the upper die base to move up and down, so as to solve the problems raised in the above background technology.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] A bearing ring forging die comprises an upper die seat and a lower die seat, an annular top plate is fixedly installed on the upper side of the lower die seat, a plurality of guide rods that penetrate the upper die seat are evenly installed between the annular top plate and the lower die seat, three hydraulic cylinders are evenly fixedly installed on the top of the annular top plate, and the output ends of the three hydraulic cylinders are commonly fixedly connected to the top wall of the upper die seat, a die-casting punch, a notch head and a punching head are evenly installed on the bottom wall of the upper die seat, and the die-casting punch, the notch head and the punching head are respectively located at the lower sides of the three hydraulic cylinders, a die-casting die, a notch die and a punching die are evenly installed on the top of the lower die seat, and the die-casting die, the notch die and the punching die are respectively located at the lower sides of the die-casting punch, the notch head and the punching head, a guide rail is fixedly installed on the top of the lower die seat, and the die-casting die, the notch die and the punching die are connected by the guide rail, a plurality of guide balls are evenly rotatably installed on the top wall of the guide rail, and the die-casting die A feeding assembly for pushing the workpiece into the die-casting die is installed on one side of the lower die seat, a rotating shaft is rotatably installed inside the lower die seat, a fan is fixedly installed on the outer wall at the bottom end of the rotating shaft, and a driving mechanism for driving the fan to rotate is installed on the lower die seat, and three driving rods for pushing the workpiece to move in the guide rail are evenly installed on the outer wall at the top end of the rotating shaft, and a limit assembly for controlling the driving rod to rotate a fixed angle is installed on the rotating shaft, and a positioning assembly for positioning the workpiece to the die-casting die, the slotting die and the punching die is installed on the lower die seat, and a cleaning assembly for cleaning the die-casting die, the slotting die and the punching die is installed inside the annular top plate. When the workpiece completes the punching process, the driving rod moves the workpiece out of the guide rail to complete the forming process. The ball bearings on the guide rail can facilitate the driving rod to move the workpiece on the guide rail. When the workpiece completes punching, the driving rod rotates to move the processed workpiece out of the guide rail for transportation. The upper die seat is used for up and down movement die casting to realize feeding, discharging and cleaning, which improves the integrity of the mold. It is designed as a ring-shaped continuous stamping structure, which occupies a small volume and works quickly and stably.

[0010] First, put the die-casting into the feed assembly, and then turn on the machine for stamping. When the upper die seat moves downward, the feed assembly is pushed to feed the workpiece to the die-casting die. The drive assembly starts to store energy by intake, and then stamping is performed to squeeze the workpiece. After the stamping is completed, the upper die seat moves upward along the guide rod. At the same time, the drive assembly starts to compress and discharge the gas to blow the fan. When the limit assembly is powered on and off, the fan rotates to drive the rotating shaft. The three drive rods installed on the rotating shaft drive the workpiece to move. The drive rod is controlled by the limit assembly to move the workpiece to the next process. After the rotation is completed, the workpiece is fixed under the corresponding punch through the positioning assembly for the next stamping. A cleaning assembly is installed on the top plate. When the upper die seat is stamped downward, the cleaning assembly will clean up all the debris retained by the stamping in the die.

[0011] Preferably, the feeding assembly includes an upper barrel installed on the top wall of the lower die base close to the die-casting die side, a plurality of workpieces are placed inside the upper barrel, a rolling wheel is fixedly installed on the upper die base, a triangular slider that cooperates with the rolling wheel is elastically installed inside the lower die base, and a pushing rod for pushing the workpiece for stamping is fixedly installed on the side of the triangular slider close to the die-casting die.

[0012] There are multiple workpieces to be die-casted stacked inside the loading barrel. The bottom of the loading barrel is supported by four pillars. When the upper die seat moves downward, the rolling wheel moves downward along the top wall of the triangular slider and pushes the triangular slider to push one side of the loading barrel. The pushing rod installed on the triangular slider punches the workpiece between the die-casting die and the die-casting punch, thereby completing the automatic loading process. The up and down movement of the upper die seat is used as the power source, and there is no need to set up an additional motor to drive the loading assembly.

[0013] Preferably, the driving mechanism includes an air bag installed between the annular top plate and the upper mold base, the bottom end of the air bag is fixedly connected to a first air pipe, a first air inlet pipe is installed on the outer wall of the first air pipe, a first one-way air inlet valve is installed on the first air inlet pipe, a first one-way air outlet valve is installed at the end of the first air pipe, a bellows is installed inside the lower mold base, and the fan is located inside the bellows, the first air pipe is connected to one side of the bellows, and the other side of the bellows is connected to the outer side of the lower mold base.

[0014] The downward movement of the upper die seat drives the airbag to move downward, and the first one-way air inlet valve takes in air, while the first one-way air outlet valve cannot take in air inward, thereby taking in air to the airbag. When the upper die seat moves upward, the airbag is squeezed to exhaust the air, and the extruded gas is passed to the inside of the bellows through the first air pipe, driving the fan to rotate, thereby converting the up and down movement of the upper die seat into the fan rotational motion, realizing the driving effect, and can drive the stamped workpiece to the next process.

[0015] Preferably, the limit assembly includes three first slots arranged on the outer wall of the bottom end of the rotating shaft, the positions of the three first slots correspond one-to-one to the positions of the three driving rods, three first electromagnets are installed on the bottom wall of the lower mold base, each of the first electromagnets is elastically installed with an iron block, and each of the iron blocks is fixedly installed with a block corresponding to the three first slots at one end away from the first electromagnet, a power-on rod is fixedly installed on the bottom wall of the annular top plate, a first joint is installed on the power-on rod, a conductive metal block is fixedly installed on the first joint, and an interface that cooperates with the first joint is installed on the outer side wall of the upper mold base, and the interface is electrically connected to each first electromagnet.

[0016] When the upper die seat moves downward, the interface on the upper die seat moves downward and contacts with the first joint on the energized rod. The circuit connects the first electromagnet to attract the iron block and the card block to leave the first slot. Since there is wind blowing the fan all the time, the fan changes and drives the rotating shaft to rotate. A conductive metal block is arranged on the first joint to extend the contact time between the first joint and the interface to ensure that the rotating shaft can rotate a certain angle. When the first joint is not in contact with the interface, the first electromagnet is powered off and loses its magnetic force. The spring restores and pushes the iron block and the card block into the first slot. The fan and the rotating shaft both stop moving. The three first slots correspond to the positions of the three driving rods, so that the rotating shaft rotates a fixed angle each time to complete the drive, thereby achieving that the rotating shaft only starts to move when the lower die seat moves downward and moves a fixed angle each time, thereby ensuring the stability of the workpiece transfer.

[0017] Preferably, the positioning assembly includes a fixed block elastically connected to the lower die base, and the fixed block is used to position the workpiece to be die-cast, a second slot is opened inside the lower die base, a second electromagnet is installed inside the second slot, a limiting block is elastically connected to the second electromagnet, a limiting groove that cooperates with the limiting block is opened on the outer wall at one end of the fixed block, a second connector electrically connected to the second electromagnet is installed on the power-on rod, and a top rod that cooperates with the fixed block is installed on the bottom wall of the upper die base.

[0018] When the fixed block protrudes from the top wall of the lower die seat, it is limiting the relative position of the workpiece, and stamping is performed at this time. At the same time, the corresponding push rod of the fixed block moves downward to squeeze the fixed block downward. When the fixed block moves to the bottom, the limit block is spring-loaded into the limit groove by the spring to complete the positioning of the fixed block. When the upper die seat moves downward, the interface on the upper die seat moves downward and contacts the second joint on the energized rod. At this time, the second electromagnet is energized to attract the iron limit block away from the limit groove, and the spring under the fixed block recovers to pop out the fixed block to position the workpiece, thereby ensuring that when the workpiece reaches the stamping position, the positioning assembly starts to position the workpiece again, ensuring the continuity of the work, avoiding stamping dislocation due to the deviation of the workpiece from the stamping, which makes the workpiece scrapped, and reduces the defective rate of the workpiece.

[0019] Preferably, the cleaning assembly includes a cylinder body evenly fixedly installed inside the annular top plate, a piston movably installed inside the cylinder body, a piston rod installed on the bottom wall of the piston, and the bottom end of the piston rod is fixedly connected to the top wall of the upper mold base, a one-way air inlet is opened on the bottom wall of the cylinder body, a hose is installed on the bottom wall of the cylinder body, and the other end of the hose is installed on the outer side of the bottom wall of the upper mold base.

[0020] When the upper die seat moves upward, it will push the piston rod upward, and the piston moves upward, so that the cylinder body can take in air through the one-way air inlet, and a one-way air outlet valve is set on the hose so that it can only exhaust air but not take in air. When the upper die seat moves downward, the piston moves downward with the piston rod, and the gas inside the cylinder body is discharged through the hose. The outlet of the hose is set to a narrow mouth, so that it has a strong cleaning ability to clean the iron filings remaining from stamping on each die, so there is no need to set up an additional air gun to clean the die, reducing the iron filings on each die, preventing the iron filings from affecting the smoothness of the workpiece surface during the stamping process, and improving the quality of the bearing ring.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The driving mechanism drives the driving rod to move the processed workpiece to the next station through the guide rail. There is no need to set up a manipulator to complete the transfer of the stamped castings. The structure is relatively simple, and the function is realized by the up and down movement of the upper die seat, and the cost is low.

[0023] 2. It has a strong cleaning ability to clean the iron chips left by stamping on each die. The cleaning work is achieved by moving the upper die base up and down, so there is no need for an additional machine to clean the die, which reduces the iron chips on each die and prevents the iron chips from affecting the smoothness of the workpiece surface during the stamping process, thereby improving the quality of the bearing ring.

[0024] 3. Position the workpiece to be processed to ensure that when the workpiece reaches the stamping position, the positioning component starts to position the workpiece, ensuring the continuity of the work, avoiding stamping dislocation caused by the workpiece deviating from the stamping, making the workpiece scrapped, and reducing the defective rate of the workpiece.

The lower die base 2 is installed with a mechanism for positioning the workpiece to the die casting die 9, the notching die 10 and the punching die 11 A cleaning assembly for cleaning the die-casting die 9, the notching die 10 and the punching die 11 is installed inside the annular top plate 3. After the workpiece completes the punching process, the driving rod 18 moves the workpiece out of the guide rail 15 to complete the forming process. The ball 28 on the guide rail 15 can facilitate the driving rod 18 to move the workpiece on the guide rail 15. The upper die seat 1 is used to move up and down to realize the feeding, discharging and cleaning work, which improves the integrity of the mold. It is designed as an annular continuous stamping structure, occupies a small volume, and works quickly and stably.

[0038] First, put the die-casting into the feed assembly, and then turn on the machine for stamping. When the upper die seat 1 moves downward, it pushes the feed assembly to feed the workpiece to the die-casting die 9, and the drive assembly starts to store energy by air intake, and then stamping is performed to squeeze the workpiece. After the stamping is completed, the upper die seat 1 moves upward along the guide rod 4. At the same time, the drive assembly starts to compress and discharge the gas to blow the fan 17. When the limit assembly is powered on and off, the fan 17 rotates to drive the rotating shaft 16 to rotate. The three drive rods 18 installed on the rotating shaft 16 drive the workpiece to move. The drive rod 18 is controlled by the limit assembly to move the workpiece to the next process. After the rotation is completed, the workpiece is fixed under the corresponding punch through the positioning assembly for the next stamping. A cleaning assembly is installed on the top plate. When the upper die seat 1 is stamped downward, the cleaning assembly will clean the debris retained by the stamping in the die.

[0039] As an embodiment of the present invention, refer to Figure 1 , Figure 3 The feeding assembly includes an upper barrel 46 installed on the top wall of the lower die base 2 close to the die-casting die 9, and multiple workpieces are placed inside the upper barrel 46. A rolling wheel 12 is fixedly installed on the upper die base 1, and a triangular slider 13 that cooperates with the rolling wheel 12 is elastically installed inside the lower die base 2. A pushing rod 14 for pushing the workpiece for stamping is fixedly installed on the side of the triangular slider 13 close to the die-casting die 9.

[0040] Multiple workpieces to be die-cast are stacked inside the loading barrel 46, and the bottom of the loading barrel 46 is supported by four pillars. When the upper die base 1 moves downward, the rolling wheel 12 moves downward along the top wall of the triangular slider 13 and pushes the triangular slider 13 to push one side of the loading barrel 46. The pushing rod 14 installed on the triangular slider 13 punches the workpiece between the die-casting die 9 and the die-casting punch 6, thereby completing the automatic loading process. The upper die base 1 is moved up and down as a power source, and there is no need to set up an additional motor to drive the loading assembly.

[0041] As an embodiment of the present invention, refer to Figure 1 , Figure 2 The driving mechanism includes an air bag 19 installed between the annular top plate 3 and the upper mold base 1, the bottom end of the air bag 19 is fixedly connected to the first air pipe 20, the outer wall of the first air pipe 20 is installed with a first air inlet pipe 21, the first air inlet pipe 21 is installed with a first one-way air inlet valve 22, the end of the first air pipe 20 is installed with a first one-way air outlet valve 23, a bellows 24 is installed inside the lower mold base 2, and the fan 17 is located inside the bellows 24, the first air pipe 20 is connected to one side of the bellows 24, and the other side of the bellows 24 is connected to the outer side of the lower mold base 2.

[0042] The downward movement of the upper die base 1 drives the airbag 19 to move downward, the first one-way air inlet valve 22 allows air to enter, and the first one-way air outlet valve 23 cannot allow air to enter, so that the airbag 19 allows air to enter. When the upper die base 1 moves upward, the airbag 19 is squeezed to exhaust the air, and the extruded gas is passed to the inside of the bellows 24 through the first air pipe 20, driving the fan 17 to rotate, thereby converting the up and down movement of the upper die base 1 into the rotational movement of the fan 17, realizing the driving effect, and driving the stamped workpiece to the next process.

[0043] As an embodiment of the present invention, refer to Figure 1 , Figure 2 , Figure 5 , Figure 6The limiting assembly includes three first slots 25 arranged on the outer wall of the bottom end of the rotating shaft 16, and the positions of the three first slots 25 correspond one by one to the positions of the three driving rods 18. Three first electromagnets 26 are installed on the bottom wall of the lower mold base 2, and an iron block 27 is elastically installed on each first electromagnet 26. A block 29 corresponding to the three first slots 25 is fixedly installed at one end of each iron block 27 away from the first electromagnet 26. An energizing rod 30 is fixedly installed on the bottom wall of the annular top plate 3, and a first joint 31 is installed on the energizing rod 30. A conductive metal block 45 is fixedly installed on the first joint 31. An interface 32 that cooperates with the first joint 31 is installed on the outer wall of the upper mold base 1, and the interface 32 is electrically connected to each first electromagnet 26.

[0044] When the upper die base 1 moves downward, the interface 32 on the upper die base 1 moves downward and contacts the first connector 31 on the power rod 30. The circuit connects the first electromagnet 26 to attract the iron block 27 and the block 29 to leave the first slot 25. Since there is wind blowing the fan 17 at this time, the fan 17 changes and drives the rotating shaft 16 to rotate. The conductive metal block 45 is arranged on the first connector 31 to extend the contact time between the first connector 31 and the interface 32 to ensure that the rotating shaft 16 can rotate a certain angle. When the first connector 31 is not in contact with the interface 32, the first electromagnet 26 is powered off and loses its magnetic force. The spring restores and pushes the iron block 27 and the block 29 into the first slot 25. The fan 17 and the rotating shaft 16 stop moving. The three first slots 25 correspond to the positions of the three driving rods 18, so that the rotating shaft 16 rotates a fixed angle each time to complete the drive, thereby realizing that the rotating shaft 16 only starts to move when the lower die base 2 moves downward and moves a fixed angle each time, thereby ensuring the stability of the workpiece transfer.

[0045] As an embodiment of the present invention, refer to Figure 1 , Figure 2 , Figure 4 The positioning assembly includes a fixed block 33 elastically connected to the lower die base 2, and the fixed block 33 is used to position the workpiece to be die-cast. A second slot 35 is provided inside the lower die base 2, and a second electromagnet 36 is installed inside the second slot 35. A limiting block 37 is elastically connected to the second electromagnet 36. A limiting groove 34 that cooperates with the limiting block 37 is provided on the outer wall at one end of the fixed block 33. A second connector 44 electrically connected to the second electromagnet 36 is installed on the power rod 30, and a top rod 47 that cooperates with the fixed block 33 is installed on the bottom wall of the upper die base 1.

[0046] When the fixed block 33 protrudes from the top wall of the lower die base 2, it is limiting the relative position of the workpiece, and stamping is performed at this time. At the same time, the push rod 47 corresponding to the fixed block 33 moves downward to squeeze the fixed block 33 downward. When the fixed block 33 moves to the bottom, the limit block 37 is spring-loaded into the limit groove 34 by the spring to complete the positioning of the fixed block 33. When the upper die base 1 moves downward, the interface 32 on the upper die base 1 moves downward and contacts the second joint 44 on the power rod 30. At this time, the second electromagnet 36 is energized to attract the iron limit block 37 away from the limit groove 34. The spring under the fixed block 33 recovers to pop out the fixed block 33 to position the workpiece to be processed, thereby ensuring that when the workpiece reaches the stamping position, the positioning assembly starts to position the workpiece again, ensuring the continuity of the work, avoiding stamping dislocation due to the deviation of the workpiece from the stamping, making the workpiece scrapped, and reducing the defective rate of the workpiece.

[0047] As an embodiment of the present invention, refer to Figure 1 , Figure 2 , Figure 7 The cleaning assembly includes a cylinder body 38 evenly fixedly installed inside the annular top plate 3, a piston 39 movably installed inside the cylinder body 38, a piston rod 40 is installed on the bottom wall of the piston 39, and the bottom end of the piston rod 40 is fixedly connected to the top wall of the upper mold base 1, a one-way air inlet 41 is opened on the bottom wall of the cylinder body 38, a hose 42 is installed on the bottom wall of the cylinder body 38, and the other end of the hose 42 is installed on the outer side of the bottom wall of the upper mold base 1.

[0048] When the upper die base 1 moves upward, it will push the piston rod 40 to move upward, and the piston 39 will move upward, so that the cylinder body 38 will take in air through the one-way air inlet 41, and a one-way air outlet valve is set on the hose 42 so that it can only exhaust air but not take in air. When the upper die base 1 moves downward, the piston 39 moves downward together with the piston rod 40, and the gas inside the cylinder body 38 is discharged through the hose 42. The outlet of the hose 42 is set to a narrow mouth, so that it has a strong cleaning ability to clean the iron filings remaining from stamping on each die, so there is no need to set up an additional air blowing device to clean the die, which reduces the iron filings on each die, prevents the iron filings from affecting the smoothness of the workpiece surface during the stamping process, and improves the quality of the bearing ring.

[0049] Working principle: First, a plurality of workpieces to be die-cast are stacked inside the loading barrel 46, and the bottom of the loading barrel 46 is supported by four pillars. When the upper die base 1 moves downward, the rolling wheel 12 moves downward along the top wall of the triangular slider 13 and pushes the triangular slider 13 to push one side of the loading barrel 46. The pushing rod 14 installed on the triangular slider 13 punches the workpiece between the die-casting die 9 and the die-casting punch 6, thereby completing the automatic loading process. The upper die base 1 is used as a power source for moving up and down, and there is no need to set up an additional motor to drive the loading assembly. Then, the machine is turned on for punching. When the upper die base 1 moves downward, it pushes the feeding assembly to supply the workpiece to the die-casting die 9. The airbag 19 is driven downward by the downward movement of the upper die base 1. The first unidirectional air intake The valve 22 allows air to enter, and the first one-way air outlet valve 23 cannot allow air to enter inward, so that the airbag 19 allows air to enter. When the upper die base 1 moves upward, the airbag 19 will be squeezed to exhaust the air, and the extruded gas will be passed to the inside of the bellows 24 through the first air pipe 20, driving the fan 17 to rotate, thereby converting the up and down movement of the upper die base 1 into the rotational movement of the fan 17, and then stamping is performed to squeeze the workpiece. After the stamping is completed, the upper die base 1 moves upward along the guide rod 4. When the upper die base 1 moves downward, the interface 32 on the upper die base 1 moves downward and contacts the first connector 31 on the power rod 30. The circuit connects the first electromagnet 26 to attract the iron block 27 and the card block 29 to leave the first card slot 25. Since there is wind blowing the fan 17 at this time, the fan 17 changes and drives the rotating shaft 16 Rotation, a conductive metal block 45 is arranged on the first joint 31 to extend the contact time between the first joint 31 and the interface 32 to ensure that the rotating shaft 16 can rotate a certain angle. When the first joint 31 is not in contact with the interface 32, the first electromagnet 26 is powered off and loses its magnetic force, the spring restores and pushes the iron block 27, the card block 29 enters the first card slot 25, the fan 17 and the rotating shaft 16 both stop moving, the three first card slots 25 correspond to the positions of the three driving rods 18, so that the rotating shaft 16 rotates a fixed angle each time to complete the drive, when the limit assembly is powered on and closed, the fan 17 rotates to drive the rotating shaft 16 to rotate, and the three driving rods 18 installed on the rotating shaft 16 drive the workpiece to move, and the driving rod 18 is controlled by the limit assembly to move the workpiece. When it comes to the next process, after the rotation is completed, the workpiece is fixed under the corresponding punch through the positioning assembly for the next stamping. When the upper die base 1 moves upward, the piston rod 40 is pushed upward, and the piston 39 moves upward, so that the cylinder body 38 takes in air through the one-way air inlet 41, and a one-way air outlet valve is set on the hose 42 so that it can only exhaust air but not take in air. When the upper die base 1 moves downward, the piston 39 moves downward with the piston rod 40, and the gas inside the cylinder body 38 is discharged through the hose 42. The outlet of the hose 42 is set to a narrow mouth, so that it has a strong cleaning ability to clean the iron filings remaining from the stamping on each die, so there is no need to set up an additional air blowing device to clean the die, reducing the iron filings on each die.It prevents iron chips from affecting the smoothness of the workpiece surface during the stamping process, and improves the quality of the bearing ring. When the upper die seat 1 is stamping downward, the cleaning component will clean the chips left in the die.
