Description

Technical Field

[0001] This utility model relates to the technical field of side frame rocker production line, specifically an automated production line for the acceptance and production of side frame rockers. Background Technology

[0002] The side frames and bolsters are the core components of railway freight car bogies, together forming the "three major bogie components" structure (consisting of two side frames and one bolster), which undertake key functions of force transmission and connection during vehicle operation. Each bogie consists of two side frames, left and right, connected by a bolster to form a triangular load-bearing frame. A circular hole is located in the center of each side frame for mounting the bolster, and both ends are connected to the wheelset via axle box assemblies. The side frames and bolsters are mainly made of cast steel, requiring control of defects such as sand inclusions and adhering sand. For wet sand casting, the sand mold compaction and moisture content need to be optimized.

[0003] After the side frame bolster is cast, it needs to be processed. Currently, the side frame bolster production line is generally set up separately, which reduces its applicability. Furthermore, when a problem is found in the product during inspection, the workpiece is usually taken out separately and then processed separately, which is inefficient. Therefore, there is an urgent need for an improved technology to solve this problem in the existing technology. Utility Model Content

After the cutting is completed, the side frame or bolster is moved to the outside of the cutting area 4 by the rotating jig 29 and held by the first truss manipulator 31 of the first hanging rail 30 and moved forward along the first hanging rail 30.

[0070] Step 4: The cut side frame or bolster is moved to the transverse roller conveyor 57 by the first truss robot 31. The transverse roller conveyor 57 moves the side frame or bolster to the third roller conveyor 32 in the air gouging area 5, and the weld seam of the side frame or bolster is processed in conjunction with the air gouging machine 33.

[0071] Step 5: The side frame or bolster after air gouging is then moved to the first tilting machine 36 at the feed end of the primary shot blasting machine 7 via the fourth roller conveyor 34 of the second transfer buffer area 6. The side frame or bolster is rotated 90° by the first tilting machine 36 and then suspended on the lifting device of the first loop-shaped hanging rail 35. The side frame or bolster follows the lifting device and enters the primary shot blasting machine 7 along the first loop-shaped hanging rail 35, and undergoes the first shot blasting treatment through the primary shot blasting machine 7.

[0072] Step Six: After the first shot blasting is completed, the material is moved to the first elevator 39 via the first tilting machine 36 at the discharge end, and then moved to the second-floor platform buffer area 8 via the first elevator 39. It is then conveyed forward by the fifth roller conveyor 41 on the second-floor platform buffer area 8. Subsequently, the bolster is moved to the bolster grinding area 10 via the fifth truss robot 56 along the fifth hanging rail 55, and the side frame is moved to the side frame grinding area 9 via the fifth truss robot 56 along the fifth hanging rail 55.

[0073] Step 7: After the side frame or bolster is polished, it is moved to the welding repair area 11 by the sixth roller conveyor 42 and the transverse roller conveyor 57 for welding repair. Then it is moved to the third hanging rail 44 by the transverse roller conveyor 57, and the side frame or bolster is moved to the first automated warehouse 12 by the third truss robot 45 to wait.

[0074] Step 8: The side frame or bolster leaving the first automated warehouse 12 is flipped by the second tilting machine 46 on one side, and then cooperates with the lifting device of the second loop-shaped hanging rail 47. The side frame or bolster passes through the tempering furnace 48 and the normalizing cooling chamber 49 in sequence, and is moved to the second automated warehouse 14 by the second tilting machine 46 on the other side to wait.

[0075] Step 9: The side frame or bolster that has been returned to normal is moved to the third tilting machine 51 on one side by the transverse roller conveyor 57. After being tilted by the third tilting machine 51, it cooperates with the lifting device of the third loop rail 50 and enters the secondary shot blasting machine 15 for the second shot blasting. Then, it is moved to the second EMS aerial conveyor line 52 by the third tilting machine 51 on the other side.

[0076] Step 10: Move the side frame or bolster to the primary magnetic particle inspection area 16 via the second EMS overhead conveyor line 52. Perform the first magnetic particle inspection using the magnetic particle detector in the primary magnetic particle inspection area 16. Then move it to the fourth overhead rail 53 via the transverse roller conveyor 57. If it fails, move it to the rotary clamp 29 in the secondary grinding area 17 via the fourth gantry robot 54. Rotate it into the secondary grinding area 17 via the rotary clamp 29 for manual secondary grinding. If it passes, move it to the transverse roller conveyor 57 between the secondary grinding area 17 and the third automated storage and retrieval system 18 via the fourth gantry robot 54. Then move it to the third automated storage and retrieval system 18 via the transverse roller conveyor 57 to wait.

[0077] Step 11: The side frame or bolster is moved to the magnetic particle detector in the secondary magnetic particle testing area 19 via the transverse roller conveyor 57 between the third automated storage and retrieval area 18 and the secondary magnetic particle testing area 19 for a second magnetic particle testing. If it fails, the side frame or bolster is moved back to the fourth hanging rail 53 via the transverse roller conveyor 57 between the secondary grinding area 17 and the third automated storage and retrieval area 18, and then moved to the rotary fixture 29 in the secondary grinding area 17 via the fourth truss robot 54 for a second grinding. If it passes, the side frame or bolster is moved to the repair area 21 along the fifth hanging rail 55 via the fifth truss robot 56.

[0078] Step 12: After reaching the size inspection area 20, a final size inspection is performed. If it passes the inspection, it moves to the storage area 22 via the transverse roller conveyor 57 between the size inspection area 20 and the storage area 22. If it fails the inspection, it moves to the repair area 21 via the transverse roller conveyor 57 between the size inspection area 20 and the repair area 21. After repair, it re-enters the size inspection area via the transverse roller conveyor 57 until it meets the requirements. Then, it moves to the storage area 22 via the transverse roller conveyor 57.

[0079] This production line mainly consists of a pallet loading area 1, a first transfer buffer area 2, a water-cooled sand removal area 3, a cutting area 4, an air gouging area 5, a second transfer buffer area 6, a primary shot blasting machine 7, a second-level platform buffer area 8, a side frame grinding area 9, a bolster grinding area 10, a welding repair area 11, a first automated storage and retrieval system 12, a normalizing area 13, a second automated storage and retrieval system 14, a secondary shot blasting machine 15, a primary magnetic particle inspection area 16, a secondary grinding area 17, a third automated storage and retrieval system 18, a secondary magnetic particle inspection area 19, a dimensional inspection area 20, a repair area 21, and a storage area 22. This enables automated production, greatly improving efficiency and significantly reducing labor costs. Furthermore, the equipment can enter the side frame grinding area 9 or the bolster grinding area 10 separately depending on whether it is a side frame or a bolster, without affecting each other, greatly expanding its applicability. The side frame or bolster is inspected on both sides through the primary magnetic particle inspection zone 16 and the secondary magnetic particle inspection zone 19. If the first magnetic particle inspection fails, it can be ground in the secondary grinding zone 17 via the corresponding transverse roller conveyor 5, the fourth hanging rail 53 and the fourth gantry robot 54. If the second magnetic particle inspection fails, it can be transferred through the third automated warehouse 18 and then ground again in the secondary grinding zone 17 via the corresponding transverse roller conveyor 5, the fourth hanging rail 53 and the fourth gantry robot 54. This ensures product quality and greatly improves efficiency without the need for manual intervention.
