Description

Technical Field

[0001] The present invention relates to the technical field of axle bridge forging, and specifically provides an automatic flipping method and device for axle bridge forging. Background Technique

[0002] Forging is a processing method that uses forging machinery to apply pressure to metal blanks, causing them to undergo plastic deformation to obtain forgings with certain mechanical properties, certain shapes, and dimensions. The axle bridge is the part on the chassis of an automobile that is connected to the wheel hub. Because its shape is similar to that of an arch bridge, it is called an axle bridge. During the processing of the axle bridge, an integral forging method is usually used to ensure the integrity and hardness of the axle bridge itself.

[0003] In the existing axle bridge forging method, the size of the heating structure is fixed. When it is necessary to process axle bridges of other specifications, the corresponding heating structure needs to be replaced, which is rather cumbersome and affects the adaptability of the equipment.

[0004] Therefore, it is necessary to design an automatic flipping method and device for axle bridge forging to address the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic flipping method and device for axle bridge forging to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the present invention provides the following technical solution: An automatic flipping method for axle bridge forging, including the following steps:

[0007] S1: Loading and heating. Clamp the axle bridge body with a robotic gripper, then move the axle bridge body to the center of the auxiliary ring. Then release one side of the robotic gripper, and drive the auxiliary ring to sleeve on the axle bridge body through the first electric slide rail and the second electric slide rail. Then let the released robotic gripper clamp the axle bridge body again. When the axle bridge body is inserted into the auxiliary ring, the elastic telescopic structure formed by the fitting wheel through the straight rod and the spring with the auxiliary ring will make the fitting wheel fit with the four sides of the axle bridge body. Thus, the size of the heating electric ring is adjusted through the fitting wheel, so that the size of the heating electric ring can match the size of the axle bridge body, enabling the equipment to adapt to axle bridge bodies of different sizes. When the size matching component adjusts the size, the upper fixed wheel and the lower fixed wheel will play a guiding role for the heating electric ring, facilitating the heating electric ring to extend out of or retract into the storage box, thus cooperating with the size adjustment of the size matching component. At the same time, due to the magnetic relationship between the permanent magnet block and the magnet sheet, the multi-joint telescopic rod can be in the extended state, so that the pushing wheel continuously pushes the heating electric ring, keeping the heating electric ring taut and also preventing the heating electric ring from winding inside the storage box. When the size matching component completes the size adaptation, power is supplied to the heating electric ring, and then relying on the electromagnetic effect, the axle bridge body is heated. The heating electric ring is driven by the first electric slide rail and the second electric slide rail to heat the entire axle bridge body;

[0008] S2: Mold feeding and conveying. Then, in the same way as putting in the axle bridge body, take out the axle bridge body from the auxiliary ring with a robotic gripper, and then put the heated axle bridge body into the first mold cavity. Drive the first mold cavity to move directly above the lifting and protecting block through the third electric slide rail, aligning it vertically with the forging hammer;

[0009] S3: Hammering and cleaning. Then drive the forging hammer to hammer and forge the axle bridge body inside the first mold cavity through the hydraulic drive cylinder. At the same time, move the cleaning component above the axle bridge body by relying on the fourth electric slide rail, the fifth electric slide rail and the multi-joint cylinder. Then turn on the first motor to drive the rotating shaft to rotate. Relying on the friction between the rolling shaft and the connecting plate, the first motor with a rotating structure formed by the mounting shaft and the connecting plate rotates 90°, making the rotating cleaning brush fall on the axle bridge body. Then drive the cleaning brush to move and clean on the surface of the axle bridge body through the second moving component;

[0010] S4: Flip and hammer. After one side of the axle bridge body is hammered and forged, drive the clamping drive assembly to move directly above the first die cavity through the sixth electric slide rail and the pushing cylinder, align the first die cavity with the second die cavity, then loosen the clamping of the clamping drive assembly, so as to place the second die cavity on the first die cavity. Then lower the clamping assembly through the sixth electric slide rail, then turn on the second motor, drive the threaded rod to rotate through the rotating disk and the friction disk, and rely on the threaded connection with the moving plate to make the clamping plate clamp the second die cavity and the first die cavity. Then, after the sixth electric slide rail rises a certain height, turn on the third motor to drive the clamping plate to rotate, flip the positions of the second die cavity and the first die cavity, so that the axle bridge body falls into the second die cavity, place the second die cavity back to the original position of the first die cavity, then clamp and move away the first die cavity through the clamping drive assembly and the clamping assembly. Then, the staff adjusts or replaces the forging hammer correspondingly, and drives the forging hammer to forge the other side of the axle bridge body through the hydraulic drive cylinder. This device can adjust the telescopic length of the extrusion push rod through the threaded sleeve before working, so as to control the thrust of the extrusion push rod on the friction disk, and further control the frictional force between the friction hook and the extrusion push rod and the friction disk, so that the clamping force of the clamping assembly during work can be controlled, thus ensuring the clamping stability;

[0011] S5: Unloading. After the axle bridge body is forged, convey the forged axle bridge body to the front end of the front housing through the third electric slide rail, and then take out and unload the axle bridge body through the mechanical claw.

[0022] 1. When the axle bridge body is inserted into the auxiliary ring in the present invention, the elastic telescopic structure formed by the fitting wheel through the straight rod and the spring with the auxiliary ring will make the fitting wheel fit with the four sides of the axle bridge body. Thus, by adjusting the size of the heating electric ring through the fitting wheel, the size of the heating electric ring can be adapted to the size of the axle bridge body, enabling the device to adapt to axle bridge bodies of different sizes and enabling the device to adapt to the processing and forging of axle bridge bodies of various sizes.

[0024] 3. In the present invention, the first motor drives the rotating shaft to rotate. Relying on the friction between the rolling shaft and the connecting disc, the first motor, which forms a rotating structure through the mounting shaft and the connecting disc, rotates 90°.

At the same time, the cleaning component can also clean the inside of the first die cavity and the second die cavity, preventing sundries from entering the inside of the second die cavity and the first die cavity, which may affect the forging effect of the device.

[0025] 4. Before the operation of the present invention, the telescopic movement of the extrusion push rod is adjusted through a threaded sleeve, so as to control the thrust of the extrusion push rod on the friction disc, and further control the frictional force between the friction hook and the extrusion push rod and the friction disc.

[0033] As Figures 1 to 6 shown, the present invention provides a technical solution: an automatic flipping axle bridge forging method, including the following steps:

[0034] S1: Loading and heating. Clamp the axle bridge body 5 with the mechanical claw 6, then move the axle bridge body 5 to the center of the auxiliary ring 401. Then loosen the mechanical claw 6 on one side, drive the auxiliary ring 401 to sleeve on the axle bridge body 5 by the first electric slide rail 201 and the second electric slide rail 202. Then let the loosened mechanical claw 6 clamp the axle bridge body 5 again. When the axle bridge body 5 is inserted into the auxiliary ring 401, the elastic telescopic structure formed by the fitting wheel 404 through the straight rod 403 and the spring 402 with the auxiliary ring 401 will make the fitting wheel 404 fit with the four sides of the axle bridge body 5. Thus, by adjusting the size of the heating electric ring 405 through the fitting wheel 404, the size of the heating electric ring 405 can be adapted to the size of the axle bridge body 5, so that the device can be adapted to axle bridge bodies 5 of different sizes. When the size matching component 4 adjusts the size, the upper fixed wheel 303 and the lower fixed wheel 304 will play a guiding role for the heating electric ring 405, facilitating the heating electric ring 405 to extend out of or be received into the receiving box 301, so as to cooperate with the size adjustment of the size matching component 4. At the same time, through the magnetic relationship between the permanent magnet block 308 and the magnet sheet 305, the multi-joint telescopic rod 306 can be in the extended state, so that the pushing wheel 307 continuously pushes the heating electric ring 405, making the heating electric ring 405 keep tight, and at the same time preventing the heating electric ring 405 from winding inside the receiving box 301. When the size matching of the size matching component 4 is completed, energize the heating electric ring 405 through the power supply 302, and then rely on the electromagnetic effect to heat the axle bridge body 5. Drive the heating electric ring 405 to heat the whole axle bridge body 5 by the first electric slide rail 201 and the second electric slide rail 202;

[0035] S2: Mold feeding and conveying. Then, in the same way as putting the axle bridge body 5, take out the axle bridge body 5 from the auxiliary ring 401 with the mechanical claw 6, and then put the heated axle bridge body 5 into the first mold cavity 9. Drive the first mold cavity 9 to move to directly above the lifting and protecting block 10 by the third electric slide rail 8, and align it with the forging hammer 1102 up and down;

[0036] S3: Hammering and cleaning. Then drive the forging hammer 1102 to hammer and forge the axle bridge body 5 inside the first mold cavity 9 by the hydraulic driving cylinder 1101. At the same time, move the cleaning component 13 to directly above the axle bridge body 5 by relying on the fourth electric slide rail 1201, the fifth electric slide rail 1202 and the multi-joint cylinder 1203. Then turn on the first motor 1302 to drive the rotating shaft 1304 to rotate. Rely on the friction force between the rolling shaft 1305 and the connecting plate 1301 to make the first motor 1302, which forms a rotating structure through the mounting shaft 1303 and the connecting plate 1301, rotate 90°, so that the rotating cleaning brush 1306 falls on the axle bridge body 5. Then drive the cleaning brush 1306 to move and clean on the surface of the axle bridge body 5 by the second moving component 12;

[0037] S4: Flip and hammer. After one side of the axle bridge body 5 is hammer-forged, the clamping drive assembly 15 is driven by the sixth electric slide rail 1401 and the pushing cylinder 1402 to move above the first die cavity 9, aligning the first die cavity 9 with the second die cavity 17. Then, the clamping drive assembly 15 releases the clamping, placing the second die cavity 17 on the first die cavity 9. Next, the clamping assembly 16 is lowered by the sixth electric slide rail 1401. Then, the second motor 1503 is turned on, and the threaded rod 1510 is driven to rotate by the rotating disk 1504 and the friction disk 1508. Relying on the threaded connection with the moving plate 1601, the clamping plate 1603 clamps the second die cavity 17 and the first die cavity 9. After the sixth electric slide rail 1401 rises a certain height, the third motor 1602 is turned on to drive the clamping plate 1603 to rotate, flipping the positions of the second die cavity 17 and the first die cavity 9, causing the axle bridge body 5 to fall into the second die cavity 17. The second die cavity 17 is placed back in the original position of the first die cavity 9. Then, the first die cavity 9 is clamped and moved away by the clamping drive assembly 15 and the clamping assembly 16. Then, the staff adjusts or replaces the forging hammer 1102 accordingly, and the forging hammer 1102 is driven by the hydraulic drive cylinder 1101 to forge the other side of the axle bridge body 5. Before working, the device can adjust the telescoping of the extrusion push rod 1505 through the threaded sleeve 1506, thereby controlling the thrust of the extrusion push rod 1505 on the friction disk 1508, and further controlling the frictional force between the friction hook 1507 and the extrusion push rod 1505 and the friction disk 1508. In this way, the clamping force of the clamping assembly 16 during operation can be controlled, ensuring clamping stability;

[0038] S5: Unloading. After the axle bridge body 5 is forged, the forged axle bridge body 5 is conveyed to the front end of the front housing 1 by the third electric slide rail 8, and then the axle bridge body 5 is taken out for unloading by the mechanical claw 6.

The size matching component 4 includes an auxiliary ring 401, a spring 402, a straight rod 403, a fitting wheel 404, and a heating electric ring 405. A spring 402 is installed inside the auxiliary ring 401, a straight rod 403 passes through the spring 402, and a fitting wheel 404 is connected to one side of the straight rod 403 close to the horizontal center line of the auxiliary ring 401. A heating electric ring 405 passes through the fitting wheel 404. Mechanical claws 6 are arranged on the left and right sides of the axle bridge body 5;

[0040] When the shaft bridge body 5 is inserted into the auxiliary ring 401, the elastic telescopic structure formed by the fitting wheel 404, the straight rod 403 and the spring 402 between the fitting wheel 404 and the auxiliary ring 401 will make the fitting wheel 404 fit with the four sides of the shaft bridge body 5. Thus, by adjusting the size of the heating electric ring 405 through the fitting wheel 404, the size of the heating electric ring 405 can be adapted to the size of the shaft bridge body 5, so that the device can be adapted to shaft bridge bodies 5 of different sizes, and the device can be adapted to the processing and forging of shaft bridge bodies 5 of various sizes.

[0043] When the size matching component 4 adjusts the size, the upper fixed wheel 303 and the lower fixed wheel 304 will play a guiding role for the heating electric ring 405, facilitating the extension or retraction of the heating electric ring 405 from the receiving box 301, so as to cooperate with the size adjustment of the size matching component 4. At the same time, through the magnetic relationship between the permanent magnet block 308 and the magnet sheet 305, the multi-section telescopic rod 306 can be in an extended state, so that the pushing wheel 307 continuously pushes the heating electric ring 405, enabling the heating electric ring 405 to remain taut and also preventing the heating electric ring 405 from winding inside the receiving box 301.

[0050] Before work, the telescopic movement of the extrusion push rod 1505 is adjusted through the threaded sleeve 1506, so as to control the thrust of the extrusion push rod 1505 on the friction disk 1508, and further control the frictional force between the friction hook 1507 and the extrusion push rod 1505 and the friction disk 1508. In this way, the clamping force of the clamping component 16 during work can be controlled, so as to ensure the clamping stability, and thus ensure the normal operation of the flipping work of the equipment.

[0051] As Figure 6 As shown, the clamping component 16 includes a moving plate 1601, a third motor 1602, and a clamping plate 1603. The third motor 1602 is installed at the lower end of the moving plate 1601, and the rotating end of the third motor 1602 is connected to the clamping plate 1603.

[0052] Working principle: First, the shaft bridge body 5 is clamped by the mechanical claw 6, then the shaft bridge body 5 is moved to the center of the auxiliary ring 401, and then one side of the mechanical claw 6 is released. The auxiliary ring 401 is driven by the first electric slide rail 201 and the second electric slide rail 202 to be sleeved on the shaft bridge body 5. Then, the released mechanical claw 6 clamps the shaft bridge body 5 again. When the shaft bridge body 5 is inserted into the auxiliary ring 401, the elastic telescopic structure formed by the fitting wheel 404 through the straight rod 403 and the spring 402 with the auxiliary ring 401 will make the fitting wheel 404 fit with the four sides of the shaft bridge body 5. Thus, by adjusting the size of the heating electric ring 405 through the fitting wheel 404, the size of the heating electric ring 405 can be adapted to the size of the shaft bridge body 5, so that the device can be adapted to shaft bridge bodies 5 of different sizes. When the size matching component 4 adjusts the size, the upper fixed wheel 303 and the lower fixed wheel 304 will play a guiding role for the heating electric ring 405, facilitating the heating electric ring 405 to extend out of or be received into the receiving box 301, so as to cooperate with the size adjustment of the size matching component 4. At the same time, due to the magnetic relationship between the permanent magnet block 308 and the magnet sheet 305, the multi-section telescopic rod 306 can be in an extended state, so that the pushing wheel 307 continuously pushes the heating electric ring 405, enabling the heating electric ring 405 to remain tight and preventing the heating electric ring 405 from winding inside the receiving box 301. When the size matching of the size matching component 4 is completed, the heating electric ring 405 is powered on by the power supply 302, and then, relying on the electromagnetic effect, the shaft bridge body 5 is heated. The heating electric ring 405 is driven by the first electric slide rail 201 and the second electric slide rail 202 to heat the entire shaft bridge body 5. Then, in the same way as the placement of the shaft bridge body 5, the shaft bridge body 5 is taken out of the auxiliary ring 401 by the mechanical claw 6, and then the heated shaft bridge body 5 is placed into the first mold groove 9. The first mold groove 9 is driven by the third electric slide rail 8 to move directly above the lifting and protecting block 10, and is aligned vertically with the forging hammer 1102. Then, the forging hammer 1102 is driven by the hydraulic drive cylinder 1101 to hammer and forge the shaft bridge body 5 inside the first mold groove 9. At the same time, the cleaning component 13 is moved above the shaft bridge body 5 by relying on the fourth electric slide rail 1201, the fifth electric slide rail 1202 and the multi-section cylinder 1203. Then, the first motor 1302 is turned on to drive the rotating shaft 1304 to rotate. Relying on the friction between the rolling shaft 1305 and the connecting plate 1301, the first motor 1302, which forms a rotating structure through the mounting shaft 1303 and the connecting plate 1301, rotates 90°, so that the rotating cleaning brush 1306 falls on the shaft bridge body 5. Then, the cleaning brush 1306 is driven by the second moving component 12 to move and clean on the surface of the shaft bridge body 5. When one side of the shaft bridge body 5 is hammered and forged, the clamping and driving component 15 is driven by the sixth electric slide rail 1401 and the pushing cylinder 1402 to move directly above the first mold groove 9, aligning the first mold groove 9 with the second mold groove 17. Then, the clamping and driving component 15 releases the clamping.Thus, the second die cavity 17 is placed on the first die cavity 9. Then, the clamping assembly 16 is lowered by the sixth electric slide rail 1401. Next, the second motor 1503 is turned on, and the threaded rod 1510 is rotated by the rotating disk 1504 and the friction disk 1508. By relying on the threaded connection with the moving plate 1601, the clamping plate 1603 clamps the second die cavity 17 and the first die cavity 9. Then, after the sixth electric slide rail 1401 rises to a certain height, the third motor 1602 is turned on to drive the clamping plate 1603 to rotate, flipping the positions of the second die cavity 17 and the first die cavity 9, so that the axle bridge body 5 falls into the second die cavity 17. The second die cavity 17 is placed back at the original position of the first die cavity 9. Then, the first die cavity 9 is clamped and moved away by the clamping drive assembly 15 and the clamping assembly 16. Then, the staff adjusts or replaces the forging hammer 1102 accordingly, and the forging hammer 1102 is driven by the hydraulic drive cylinder 1101 to forge the other side of the axle bridge body 5. This device can adjust the telescoping of the extrusion push rod 1505 through the threaded sleeve 1506 before work, thereby controlling the thrust of the extrusion push rod 1505 on the friction disk 1508, and further controlling the frictional force between the friction hook 1507 and the extrusion push rod 1505 and the friction disk 1508. In this way, the clamping force of the clamping assembly 16 during work can be controlled, thus ensuring clamping stability. When the forging of the axle bridge body 5 is completed, the forged axle bridge body 5 is conveyed to the front end of the front housing 1 by the third electric slide rail 8, and then the axle bridge body 5 is taken out and unloaded by the mechanical claw 6.,
