The high-speed forging machine for bearing rings is installed by installing a screw on the output shaft of the forward and reverse motors, installing the forward and reverse motors at the bottom of the slide plates, the slide plates are installed on the support rods, the limit plates are installed in the middle of the support legs, the screws are threadedly sleeved with the limit plates, and the forward and reverse motors are used to drive the screws to rotate and move downward at the same time, so that the fixing device on the screws is clamped inside the mold for fixing, and the bottom end of the screws penetrates into the inside of the base, thereby improving the stability of the fixing of the high-speed forging machine for bearing rings.

[0004] During the process of upsetting the bearing rings, the above-mentioned upsetting machine cannot automatically load and unload the bearing rings. The lack of automatic loading and unloading functions means that the bearing rings need to be manually placed into the mold for upsetting, thereby reducing the production efficiency of the entire upsetting machine. Summary of the invention

[0005] The purpose of the present invention is to provide an integrated intelligent bearing ring blank multi-station forging system and a control method thereof, so as to solve the technical problem that the bearing ring cannot be automatically loaded and unloaded during the existing bearing ring forging process proposed in the above background technology, resulting in low production efficiency.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] An integrated intelligent multi-station forging system for bearing ring blanks comprises an operating table, a heating mechanism and a forging mechanism are fixedly installed on the upper surface of the operating table, a feeding conveyor belt and a discharging conveyor belt are drivingly installed on both sides of the heating mechanism and the forging mechanism, a connecting plate is fixedly installed at one end of the operating table, a first electric push rod is fixedly installed on the upper surface of the connecting plate, a C-shaped push plate is fixedly installed on one end of the piston rod of the first electric push rod, so that the first electric push rod can push the bearing ring blank conveyed from the upper surface of the feeding conveyor belt into between the heating mechanisms through the C-shaped push plate.

[0008] After the bearing ring blank is heated by the heating mechanism, it can be pushed to the bottom of the forging mechanism again by the C-shaped push plate at one end of the piston rod of the first electric push rod, so that the forging mechanism can be inserted into the inner ring wall of the bearing ring blank, thereby enabling the forging mechanism to drive the bearing ring blank to rotate, so that the outer surface of the bearing ring blank is pressed and shaped by the forging mechanism under the pressure.

[0009] As a further solution of the present invention, a proximity sensor is fixedly installed at the central part of one end of the C-shaped push plate, so that the first electric push rod can detect through the proximity sensor that the bearing ring blank is transported to the front by the feeding conveyor belt and can automatically push it to between the heating mechanisms. After the heating mechanism is heated for a specific time, it can retract and start the first electric push rod again to send the bearing ring blank to the bottom of the forging mechanism. After the bearing ring blank is forged, the first electric push rod will be started again to push the bearing ring blank to the discharge conveyor belt to be transported away.

[0010] The three pushing strokes of the first electric push rod are all controlled by a controller, and a signal receiving end of the controller is connected to a signal transmitting end of the proximity sensor.

The electromagnetic induction heating ring can be pushed and pulled out of the operating table by the second electric push rod to surround the bearing ring blank.

[0012] As a further scheme of the present invention, the upsetting mechanism includes two groups of guide plates, which are fixedly mounted on the upper surface of the operating table, and third electric push rods are fixedly mounted on the upper surfaces of the two groups of guide plates. A mounting plate is fixedly mounted between the piston rods of the two groups of third electric push rods, and both sides of the mounting plate are made to slide in the two groups of guide plates. A motor is fixedly mounted on the upper surface of the mounting plate, and the output shaft of the motor passes through the lower surface of the mounting plate and a plug-in column is fixedly mounted on the end thereof. The plug-in column can be driven by the third electric push rod to be inserted into the inner ring wall of the bearing ring blank to drive it to rotate.

[0013] As a further solution of the present invention, hydraulic rods are fixedly installed on both sides of the two groups of guide plates. The piston rods of the hydraulic rods penetrate into the guide plates and roller wheels are fixedly installed on the ends, so that the roller wheels can be pushed and pressed against the outer surface of the bearing ring blank by the hydraulic rods and driven to rotate with the bearing ring blank, so that the bearing ring blank can be pressurized and rolled to shape.

[0014] The second electric push rod, the third electric push rod, the motor and the hydraulic rod are also controlled by the controller so that they can be started in sequence. The models of the controller and the proximity sensor are IFM IS1503 and S7-1200 PLC respectively.

[0016] As a further solution of the present invention, two groups of second air pipes are installed on the upper surface of the sealing cover, and the other ends of the two groups of second air pipes pass through the mounting plate and are connected to the suction port and exhaust port of the vacuum pump, and the vacuum pump is fixedly installed at one end of the upper surface of the mounting plate.

[0017] As a further solution of the present invention, when the plug-in column is driven to rotate by the motor, the sealing cover can be kept in place in the ventilation ring groove, so that the plug-in column can maintain the second air pipe and the piston groove in communication during the rotation process.

[0018] As a further solution of the present invention, the piston groove can be supplied with air by a vacuum pump to push the piston column in the piston groove out and press it against the inner ring wall of the bearing ring blank. At the same time, the air in the piston groove can also be extracted by the vacuum pump so that the piston column in the piston groove can be pulled into the piston groove.

[0019] The present invention also provides a control method for an integrated intelligent bearing ring blank multi-station forging system, comprising the following steps:

[0020] S1. When processing the bearing ring blank, the feeding conveyor belt can convey the bearing ring blank to be flush with the C-shaped push plate at one end of the first electric push rod, so that the proximity sensor in the C-shaped push plate can detect it and send a signal to the controller, and the controller can control the first electric push rod to push the first stroke, so that the first electric push rod can push the bearing ring blank between the two sets of heat insulation frames through the C-shaped push plate;

[0021] S2, after the first stroke of the first electric push rod is completed, the controller can control the second electric push rod to lift the L-shaped plate at one end of the piston rod, and the L-shaped plate can drive the electromagnetic induction heating ring sleeve fixed at one end to heat the outer surface of the bearing ring blank;

[0022] S3, and the lifting time of the second electric push rod is the heating time of the electromagnetic induction heating ring on the bearing ring blank. After the end, the controller can start the first electric push rod again to drive the C-shaped push plate to push the heated bearing ring blank to between the two sets of guide plates, which is the second stroke push of the second electric push rod. After the second pushing stroke of the second electric push rod is completed, the controller can control the third electric push rod to push the mounting plate fixedly installed between the piston rods to slide vertically in the guide plate, so that the mounting plate can drive the plug-in column to insert into the inner ring wall of the bearing ring blank. Until the pushing stroke of the third electric push rod reaches the set value, the controller can start the vacuum pump and the motor, and the vacuum pump can pass through the second air pipe and The first air pipe injects air into the piston groove of the insertion column, so that the piston column slidably installed in the piston groove can be pushed out by the injected air, so that the piston column can drive the top clamping plate fixed at one end to press on the inner ring wall of the bearing ring blank, so that the motor can drive the bearing ring blank clamped on the outer surface of the insertion column to rotate, and after the vacuum pump and the motor are started, the controller can control the two groups of hydraulic rods to push the roller pressing wheel at one end of the piston rod to press on the outer surface of the bearing ring blank, so that pressure can be applied to the bearing ring blank to form a convex disc at the upper and lower ends of the outer surface, so that the part pressed by the roller pressing wheel is recessed inward, thereby realizing the operation of forging and shaping the bearing ring blank;

[0023] S4. After the operation time of upsetting and shaping is over, the controller can control the first electric push rod to perform the third stroke push again, so that the first electric push rod pushes the roller-shaped bearing ring blank to the discharge conveyor belt through the C-shaped push plate at one end of the piston rod to be transported away for cooling or storage. Each pushing stroke of the first electric push rod will increase in sequence to push the bearing ring blank into different processing positions, and the controller will control it in sequence according to the above order, thus completing the processing operation of the bearing ring blank.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] When processing the bearing ring blank, the feeding conveyor belt can transport the bearing ring blank to be flush with the C-shaped push plate at one end of the first electric push rod, so that the proximity sensor in the C-shaped push plate detects the bearing ring blank, and the proximity sensor sends a signal to the controller, and the controller can control the first electric push rod to perform the first stroke push, so that the first electric push rod can push the bearing ring blank to between the heating mechanisms through the C-shaped push plate. After the first stroke push of the first electric push rod is completed, the controller can control the heating mechanism to lift and surround the outer surface of the bearing ring blank to be heated. After the heating time of the bearing ring blank by the heating mechanism is over, the controller can start the first electric push rod again to drive the C-shaped push plate to push the heated bearing ring blank to the forging mechanism, which is the second stroke push of the second electric push rod. After the second pushing stroke of the second electric push rod is over, the controller can control the forging mechanism to insert into the inner ring wall of the bearing ring blank and drive it to rotate, and while driving the bearing ring blank to rotate, the forging end in the forging mechanism is pressed against the outer surface of the bearing ring blank, so that the bearing ring blank can be pressurized for roller shaping. After the shaping operation time is over, the controller can control the first electric push rod to push the third stroke again, so that the first electric push rod pushes the roller-shaped bearing ring blank to the discharge conveyor belt through the U-shaped push plate at one end of the piston rod to be transported away for cooling or storage. Each pushing stroke of the first electric push rod will increase in sequence to push the bearing ring blank into different processing positions, and the controller will control it in sequence according to the above sequence, thus completing the processing operation of the bearing ring blank. The entire processing process is controlled by the controller in a coordinated manner, realizing automated operation, and the feeding conveyor belt automatically pushes The blank is transported to the specified position, and the proximity sensor detects and sends a signal to the controller. The controller controls the pushing of the first electric push rod and the action of each processing mechanism in sequence. This automated process reduces manual intervention, greatly improves processing efficiency, and enables the entire processing process to be carried out in sequence. Each process is closely connected, from feeding, heating, upsetting to discharge, and each step is completed under the orderly control of the controller. This continuity helps to reduce quality problems that may arise due to improper process connection, such as uneven temperature changes, processing stress concentration, etc., thereby ensuring the stability of the processing quality of the bearing ring blank.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0039] See also Figure 1-Figure 8 As shown, the embodiment of the present invention provides the following technical solutions:

[0040] like Figure 1-Figure 2 As shown, an integrated intelligent bearing ring blank multi-station forging system includes an operating table 1, a heating mechanism 2 and a forging mechanism 3 are fixedly installed on the upper surface of the operating table 1, a feeding conveyor belt 101 and a discharging conveyor belt 102 are driven and installed on both sides of the heating mechanism 2 and the forging mechanism 3, a connecting plate 103 is fixedly installed at one end of the operating table 1, a first electric push rod 104 is fixedly installed on the upper surface of the connecting plate 103, and a C-shaped push plate 105 is fixedly installed on one end of the piston rod of the first electric push rod 104, so that the first electric push rod 104 can push the bearing ring blank conveyed from the upper surface of the feeding conveyor belt 101 into between the heating mechanisms 2 through the C-shaped push plate 105.

[0041] After the bearing ring blank is heated by the heating mechanism 2, it can be pushed to the bottom of the forging mechanism 3 again by the C-shaped push plate 105 at one end of the piston rod of the first electric push rod 104, so that the forging mechanism 3 can be inserted into the inner ring wall of the bearing ring blank, thereby enabling the forging mechanism 3 to drive the bearing ring blank to rotate, so that the outer surface of the bearing ring blank is pressed and shaped by the forging mechanism 3 under the pressure.

[0042] A proximity sensor is fixedly installed at the center of one end of the U-shaped push plate 105, so that the first electric push rod 104 can detect through the proximity sensor that the bearing ring blank is transported to the front by the feeding conveyor belt 101 and can automatically push it to the heating mechanism 2. After the heating mechanism 2 is heated for a specific time, it can retract and start the first electric push rod 104 again to send the bearing ring blank to the bottom of the forging mechanism 3. After the bearing ring blank is forged, the first electric push rod 104 will be started again to push the bearing ring blank to the discharge conveyor belt 102 for transportation.

[0043] The three pushing strokes of the first electric push rod 104 are all controlled by a controller, and a signal receiving end of the controller is connected to a signal transmitting end of the proximity sensor.

[0044] When processing the bearing ring blank, the feeding conveyor belt 101 can transport the bearing ring blank to be flush with the C-shaped push plate 105 at one end of the first electric push rod 104, so that the proximity sensor in the C-shaped push plate 105 can detect it and send a signal to the controller, and the controller can control the first electric push rod 104 to push the first stroke, so that the first electric push rod 104 can push the bearing ring blank to between the heating mechanisms 2 through the C-shaped push plate 105. After the first stroke push of the first electric push rod 104 is completed, the controller can control the heating mechanism 2 to lift and surround the outer surface of the bearing ring blank. The surface is heated, and after the heating time of the bearing ring blank by the heating mechanism 2 is over, the controller can start the first electric push rod 104 again to drive the C-shaped push plate 105 to push the heated bearing ring blank to the forging mechanism 3, which is the second stroke push of the second electric push rod 201. After the second pushing stroke of the second electric push rod 201 is over, the controller can control the forging mechanism 3 to insert into the inner ring wall of the bearing ring blank and drive it to rotate, and while driving the bearing ring blank to rotate, the forging end in the forging mechanism 3 is pressed against the outer surface of the bearing ring blank, so that the bearing ring blank can be pressed. The roller forming is performed. After the roller forming operation time is over, the controller can control the first electric push rod 104 to perform the third stroke push again, so that the first electric push rod 104 pushes the roller-formed bearing ring blank to the discharge conveyor belt 102 through the U-shaped push plate 105 at one end of the piston rod to be transported for cooling or storage. Each push stroke of the first electric push rod 104 will increase in sequence to push the bearing ring blank into different processing positions, and the controller controls it in sequence according to the above sequence, that is, the processing operation of the bearing ring blank is completed, so that the entire processing process is collaboratively controlled by the controller, and automatic operation is realized. The feeding conveyor belt 101 automatically transports the blank to the specified position, and the proximity sensor detects and sends a signal to the controller. The controller controls the pushing of the first electric push rod 104 and the action of each processing mechanism in sequence. This automated process reduces manual intervention, greatly improves processing efficiency, and enables the entire processing process to be carried out in sequence. Each process is closely connected, from feeding, heating, forging to discharge, and each step is completed under the orderly control of the controller. This continuity helps to reduce quality problems that may arise due to improper process connection, such as uneven temperature changes, processing stress concentration, etc., thereby ensuring the stability of the processing quality of the bearing ring blank.

[0045] like Figure 3As shown, the heating mechanism 2 includes two groups of insulation frames 204, in which the second electric push rods 201 are fixedly installed, one end of the piston rod of the second electric push rod 201 is fixedly installed with an L-shaped plate 202, and one end of the L-shaped plate 202 is fixedly installed with an electromagnetic induction heating ring 203. The electromagnetic induction heating ring 203 can be pushed by the second electric push rod 201 to be pulled out from the operating table 1 to surround the bearing ring blank.

[0046] After the first electric push rod 104 pushes the bearing ring blank to between the two sets of heat insulation frames 204 through the U-shaped push plate 105, the controller can control the second electric push rod 201 to lift the L-shaped plate 202 at one end of the piston rod, and the L-shaped plate 202 can drive the electromagnetic induction heating ring 203 fixedly installed at one end to be lifted from the operating table 1, so that the electromagnetic induction heating ring 203 is surrounded by the outer surface of the bearing ring blank for heating treatment, and after the heating is completed, the electromagnetic induction heating ring 203 can be driven by the second electric push rod 201 to lift the L-shaped plate 202 at one end of the piston rod. The push rod 201 is pulled down and stored back into the operating table 1, so that the first electric push rod 104 can push it to the upset forging processing station, and the heating process is uniformly controlled by the controller. The controller can accurately control the movement of the second electric push rod 201, thereby determining the lifting and lowering of the electromagnetic induction heating ring 203, as well as the start and end of heating. In this way, effective control of parameters such as heating time and heating temperature can be achieved, which helps to unify the heated quality of each group of bearing ring blanks and enable the bearing ring blanks to reach an ideal heating state.

[0047] like Figure 4-Figure 8 As shown, the upsetting mechanism 3 includes two groups of guide plates 301, and the two groups of guide plates 301 are fixedly installed on the upper surface of the operating table 1. The upper surfaces of the two groups of guide plates 301 are fixedly installed with third electric push rods 304. A mounting plate 305 is fixedly installed between the piston rods of the two groups of third electric push rods 304, and the two sides of the mounting plate 305 are made to slide in the two groups of guide plates 301. A motor 306 is fixedly installed on the upper surface of the mounting plate 305. The output shaft of the motor 306 passes through the lower surface of the mounting plate 305 and a plug-in column 307 is fixedly installed on the end thereof. The plug-in column 307 can be driven by the third electric push rod 304 to be inserted into the inner ring wall of the bearing ring blank and drive it to rotate.

[0048] Hydraulic rods 302 are fixedly installed on both sides of the two sets of guide plates 301. The piston rods of the hydraulic rods 302 penetrate into the guide plates 301 and a rolling wheel 303 is fixedly installed on the end, so that the rolling wheel 303 can be pushed and pressed against the outer surface of the bearing ring blank by the hydraulic rods 302 and rotated with the bearing ring blank, so that the bearing ring blank can be pressed and shaped by pressure.

[0049] The second electric push rod 201, the third electric push rod 304, the motor 306 and the hydraulic rod 302 are also controlled by the controller so that they can be started in sequence. The models of the controller and the proximity sensor are IFM IS1503 and S7-1200PLC respectively.

[0050] A ventilation ring groove 312 is provided on the upper surface of the plug-in column 307, and a sealing cover 310 is sealed and rotated in the ventilation ring groove 312. A first air pipe 311 is connected and installed in the ventilation ring groove 312, and the other end of the first air pipe 311 is connected to the piston groove 313. The piston groove 313 is provided on the outer surface of the plug-in column 307, and a piston column 309 is slidably installed in the plug-in column 307, and a top clamp is fixedly installed at one end of the piston column 309.

[0051] Two sets of second air pipes 314 are installed on the upper surface of the sealing cover 310 . The other ends of the two sets of second air pipes 314 pass through the mounting plate 305 and are connected to the suction port and exhaust port of the vacuum pump 308 . The vacuum pump 308 is fixedly installed on one end of the upper surface of the mounting plate 305 .

[0052] When the plug-in column 307 is driven to rotate by the motor 306 , the sealing cover 310 can be kept in position unchanged in the ventilation ring groove 312 , so that the plug-in column 307 can maintain the second air pipe 314 and the piston groove 313 in the process of rotation.

[0053] The piston groove 313 can be supplied with air by the vacuum pump 308 to push the piston column 309 in the piston groove 313 out and press it against the inner ring wall of the bearing ring blank. At the same time, the vacuum pump 308 can also extract the air in the piston groove 313 so that the piston column 309 in the piston groove 313 can be pulled into the piston groove 313.

[0054] After the heating time of the bearing ring blank is over, the controller can start the first electric push rod 104 again to drive the U-shaped push plate 105 to push the heated bearing ring blank to between the two sets of guide plates 301, which is the second push stroke of the second electric push rod 201. After the second push stroke of the second electric push rod 201 is completed, the controller can control the third electric push rod 304 to push the mounting plate 305 fixedly installed between the piston rods to slide vertically in the guide plate 301, so that the mounting plate 305 can drive the plug-in column 307 to insert the bearing sleeve The inner ring wall of the bearing ring blank is pressed into the inner ring wall of the bearing ring blank until the pushing stroke of the third electric push rod 304 reaches the set value, and the controller can start the vacuum pump 308 and the motor 306, and the vacuum pump 308 can inject air into the piston groove 313 of the plug-in column 307 through the second air pipe 314 and the first air pipe 311, so that the piston column 309 slidably installed in the piston groove 313 can be pushed out by the injected air, and then the piston column 309 can drive the top clamping plate fixed at one end to press on the inner ring wall of the bearing ring blank, so that the motor 306 can drive the The bearing ring blank on the outer surface of the insertion column 307 of the top clamp rotates, and after the vacuum pump 308 and the motor 306 are started, the controller can control the two sets of hydraulic rods 302 to push the roller 303 at one end of the piston rod to press on the outer surface of the bearing ring blank, so that pressure can be applied to the bearing ring blank to form a convex disc at the upper and lower ends of the outer surface, and the part pressed by the roller 303 is recessed inward, thereby realizing the operation of forging and shaping the bearing ring blank, and the entire forging and shaping operation is an automated process. The controller starts the actions of each component in sequence according to the set conditions, without frequent manual intervention. This automated operation can reduce the time required for manual operation, increase processing speed, and significantly improve production efficiency during batch production of bearing rings. The fixing effect of the insert column 307 and the top clamping plate allows the bearing ring blank to be evenly stressed during rotation. During subsequent processing, the even stress helps to ensure machining uniformity and avoid machining quality problems caused by excessive or insufficient local stress, such as uneven surface and irregular shape.

[0055] The embodiment of the present invention further provides an integrated intelligent bearing ring blank multi-station upsetting system and a control method thereof, comprising the following steps:

[0056] S1. When processing the bearing ring blank, the feeding conveyor belt 101 can transport the bearing ring blank to be flush with the C-shaped push plate 105 at one end of the first electric push rod 104, so that the proximity sensor in the C-shaped push plate 105 can detect it and send a signal to the controller, and the controller can control the first electric push rod 104 to push the first stroke, so that the first electric push rod 104 can push the bearing ring blank to between the two sets of insulation frames 204 through the C-shaped push plate 105.

[0057] S2. After the first stroke push of the first electric push rod 104 is completed, the controller can control the second electric push rod 201 to lift the L-shaped plate 202 at one end of the piston rod, and the L-shaped plate 202 can drive the electromagnetic induction heating ring 203 fixedly installed at one end to surround the outer surface of the bearing ring blank for heating treatment.
