Description

Technical Field

[0001] The invention relates to the technical field of bearing production, and in particular to a safe production forging production line for protecting loading and unloading of bearing parts. Background Art

[0002] In the field of mechanical manufacturing, bearings are used more and more widely. Bearings are a component used to determine the relative motion position of the rotating shaft and other parts, and to support or guide. They are components that bear gravity and transmit power. The main parts of a bearing are inner and outer rings, rolling elements and cages. The quality of the inner and outer rings determines the service life to a large extent. The forging of bearing rings is a typical type of processing in mechanical forging. Most bearing rings are made of high-carbon chromium bearing steel (GCr15 and GCr15SiMn and ZGCr15 and ZGCr15SiMn). The hardness of the parts is as follows: rings made of GCr15 and ZGCr15 are HRc61-65; rings made of GCr15SiMn and ZGCr15SiMn are HRc60-64; bearings made of high-carbon steel chromium bearing steel are generally suitable for working temperatures ranging from -40 to 130°C, and oil and grease lubrication are normal.

[0003] In the production process of the existing bearing inner ring, it is necessary to manually place the heated blank in different forging equipment for forging many times, which has a low degree of automation and seriously affects the production efficiency. Summary of the invention

[0006] Preferably, the clamp comprises an electric push rod 1, the top end of the electric push rod 1 is fixedly connected to a slider of an electric slide table 1, and the driving end of the electric push rod 1 is fixedly connected to a connecting cover.

[0007] Preferably, a second electric push rod is symmetrically fixedly connected to the lower side of the connection cover, and a clamping block is fixedly connected to the driving end of the second electric push rod.

[0008] Preferably, an intercepting plate is fixedly connected to the outer wall of the connecting column.

[0009] Preferably, the forged limiting sleeve comprises a semi-ring body 1 and a semi-ring body 2, and both sides of the semi-ring body 1 and the semi-ring body 2 are respectively fixedly connected with spring telescopic rods.

[0010] Preferably, the transfer assembly further comprises a limiting frame, the bottom end of which is fixedly connected to the upper surface of the processing table, and the limiting frame comprises a straight section and an inclined section.

[0011] Preferably, a cooling component is installed on one side of the processing table, and the cooling component includes a cooling water tank and a support frame 2, and the cooling water tank and the support frame 2 are both fixed on the ground. The inner top wall of the support frame 2 is fixedly connected to an electric slide 3, the slider of the electric slide 3 is fixedly connected to an electric push rod 3, and the driving end of the electric push rod 3 is fixedly connected to the cooling table.

[0012] Preferably, two baffles are fixedly connected to the upper surface of the cooling water tank, and a conveyor belt is installed on one side of the cooling water tank.

[0013] Preferably, the cooling table comprises a fixed plate, one end of which is rotatably connected to a perforated plate via a torsion spring shaft, a lower side wall of the fixed plate is fixedly connected to a limiting protrusion, and a limiting groove is provided on the lower surface of the perforated plate.

[0014] Preferably, a material discharge piece is fixedly connected above the frame of the conveyor belt, and the material discharge piece is configured to be T-shaped.

[0015] Working principle: The heated inner ring blank is placed inside the positioning sleeve for positioning, and the positioning sleeve containing the inner ring blank is transported to the bottom of the fixture through the blank conveyor belt, and the blank is transferred to the inside of the forging limit sleeve through the fixture. The forging limit sleeve is driven by the electric slide table 2 to move to the bottom of the three groups of cylinders in sequence for forging, and the inner ring blank is forged gradually into an inner ring with the required size. No manual operation is required, which improves the safety during forging, has a high degree of automation, and effectively increases production efficiency.

[0016] When the blank is transported by the clamp, the clamp is driven by the electric slide to move to the bottom of the positioning sleeve, the electric push rod 1 is controlled to extend so that the connecting cover is closed on the outside of the positioning sleeve, and the electric push rod 2 is operated to extend so that the clamp block is against the blank to clamp and fix it. Then the electric push rod 1 contracts to drive the blank to rise, and the electric slide 1 moves the blank to the top of the forging limit sleeve, and the electric push rod 1 extends again to make the blank drop to the inside of the forging limit sleeve. Finally, the electric push rod 2 is controlled to contract, so that the blank can be moved from the positioning sleeve to the forging limit sleeve, thereby realizing the automatic transportation of the blank.

[0017] After the forging of the blank is completed, the electric slide table 2 drives the forging limit sleeve to move to the inclined section. At this time, the extrusion pressure on the semi-ring body 2 is gradually reduced, and the semi-ring body 1 and the semi-ring body 2 are gradually stretched apart by the elastic force of the spring telescopic rod, so that the inner ring sleeve after forging can fall off from the forging limit sleeve.

[0018] The cooling table is driven by the electric slide table to move to the drop point of the inner ring, so that the inner ring can be supported when it falls to avoid collision when the inner ring falls. Then the electric push rod is extended to drive the cooling table and the inner ring to descend to the inside of the cooling water tank, and the inner ring is cooled by the cooling water inside the cooling water tank, so that the inner ring is quickly cooled.

[0019] After cooling is completed, the electric push rod 3 contracts to drive the cooling table out of the water tank, and then the cooling table is moved to the top of the blanking piece through the electric slide 3. The electric push rod 3 is controlled to extend to make the cooling table descend. When the cooling table descends, the blanking piece presses against the orifice plate, causing the orifice plate to tilt, so that the cooled inner ring slides from the cooling table to the conveyor belt, and is finally transported away by the conveyor belt, realizing the automatic transportation of the inner ring.

[0020] The present invention provides a safe production forging production line for protecting the loading and unloading of bearing parts. It has the following beneficial effects: 1. The present invention drives the forging limit sleeve to move to the bottom of the three groups of cylinders in sequence through the electric slide table 2 for forging, and gradually forges the inner ring sleeve blank into an inner ring sleeve with the required size. No manual operation is required, the safety during forging is improved, the degree of automation is high, and the production efficiency is effectively increased.

[0021] 2. After the forging of the present invention is completed, the electric slide table 2 drives the forging limit sleeve to move to the inclined section. At this time, the extrusion pressure on the semi-ring body 2 is gradually reduced, and the semi-ring body 1 and the semi-ring body 2 are gradually stretched apart by the elastic force of the spring telescopic rod, so that the inner ring sleeve after forging can fall off from the forging limit sleeve.

[0022] 3. The present invention drives the cooling table to move to the drop point of the inner ring through the electric slide table 3, so that the inner ring can be supported when the inner ring falls to avoid collision when the inner ring falls. Then the electric push rod 3 extends to drive the cooling table and the inner ring to descend to the inside of the cooling water tank, and the inner ring is water-cooled by the cooling water inside the cooling water tank, so as to quickly cool the inner ring.

[0023] 4. The present invention moves the cooling table to the top of the blanking piece by means of the electric slide table three, and controls the electric push rod three to extend to make the cooling table descend. When the cooling table descends, the blanking piece presses against the orifice plate, causing the orifice plate to tilt, so that the cooled inner ring sleeve slides from the cooling table to the conveyor belt, and is finally transported away by the conveyor belt, thereby realizing the automatic transportation of the inner ring sleeve.

A processing table 3 is installed on one side of the blank conveyor belt 1, and a support frame 4 is installed on one side of the processing table 3. The inner top wall of the support frame 4 is fixedly connected with a plurality of cylinders 5, and the driving end of the cylinder 5 is fixedly connected with a forging round head 6, and the inner top wall of the support frame 4 is fixedly connected with an electric slide table 1. 7. A transfer assembly 8 is installed on the surface of the processing table 3. The transfer assembly 8 includes an electric slide 81 and a clamp 84. The lower surface of the electric slide 81 is fixedly connected to the upper surface of the processing table 3. The slider of the electric slide 81 is fixedly connected to a connecting column 82. One end of the connecting column 82 is fixedly connected to a forging limit sleeve 83. The clamp 84 is used to move the blank from the positioning sleeve 2 to the forging limit sleeve 83. The sizes of the multiple forged round heads 6 gradually increase according to the conveying direction of the blank, and the diameter of the last forged round head 6 is equal to the inner diameter of the inner ring.

[0028] Specifically, the cylinder 5 drives the forging round head 6 to descend to forge the blank in the forging limit sleeve 83. When in use, the heated inner ring blank is placed inside the positioning sleeve 2 for positioning, and the positioning sleeve 2 containing the inner ring blank is transported to the bottom of the clamp 84 through the blank conveyor belt 1. The blank is transferred to the inside of the forging limit sleeve 83 through the clamp 84, and the forging limit sleeve 83 is driven by the electric slide 2 81 to move to the bottom of the three groups of cylinders 5 in turn for forging. The inner ring blank is forged gradually into an inner ring of the size that meets the requirements. No manual operation is required, which improves the safety during forging, has a high degree of automation, and effectively increases production efficiency.

[0029] Please refer to the attached Figure 4 The clamp 84 includes an electric push rod 841, the top of which is fixedly connected to the slider of the electric slide 7, the driving end of the electric push rod 841 is fixedly connected to a connecting cover 842, the lower side of the connecting cover 842 is symmetrically fixedly connected to an electric push rod 843, and the driving end of the electric push rod 843 is fixedly connected to a clamping block 844.

[0030] Specifically, when the blank is transported by the clamp 84, the clamp 84 is driven by the electric slide 7 to move to the bottom of the positioning sleeve 2, the electric push rod 841 is controlled to extend so that the connecting cover 842 covers the outside of the positioning sleeve 2, and the electric push rod 843 is operated to extend so that the clamp block 844 presses against the blank to clamp and fix it, and then the electric push rod 841 contracts to drive the blank to rise, and the electric slide 7 moves the blank to the top of the forging limit sleeve 83, and the electric push rod 841 extends again to make the blank drop to the inside of the forging limit sleeve 83, and finally the electric push rod 843 is controlled to contract, so that the blank can be moved from the positioning sleeve 2 to the forging limit sleeve 83, thereby realizing the automatic transportation of the blank.

[0031] Please refer to the attached Figure 3 The outer wall of the connecting column 82 is fixedly connected with an intercepting plate 85.

[0032] Specifically, the interception plate 85 is used to intercept the debris generated by the forging of the blank to prevent the debris from splashing onto the surface of the lead screw of the electric slide 2 81 .

[0033] Please refer to the attached Figure 5 The forging limit sleeve 83 includes a semi-ring body 1 831 and a semi-ring body 2 832, and spring telescopic rods 833 are fixedly connected to both sides of the semi-ring body 1 831 and the semi-ring body 2 832 respectively. The transfer assembly 8 also includes a limit frame 86, and the bottom end of the limit frame 86 is fixedly connected to the upper surface of the processing table 3. The limit frame 86 includes a straight section 861 and an inclined section 862.

[0034] Specifically, the straight section 861 cooperates with the connecting column 82 to press against the semi-ring body 1 831 and the semi-ring body 2 832, so that the forging limit sleeve 83 is closed for the forging of the blank. After the forging of the blank is completed, the electric slide 2 81 drives the forging limit sleeve 83 to move to the inclined section 862. At this time, the extrusion pressure on the semi-ring body 2 832 is gradually reduced, and the semi-ring body 1 831 and the semi-ring body 2 832 are gradually stretched open by the elastic force of the spring telescopic rod 833, so that the inner ring after forging can fall off from the forging limit sleeve 83.

[0035] Please refer to the attached Figure 6 -Attached Figure 7 A cooling assembly 9 is installed on one side of the processing table 3. The cooling assembly 9 includes a cooling water tank 91 and a supporting frame 92. The cooling water tank 91 and the supporting frame 92 are both fixed on the ground. The inner top wall of the supporting frame 92 is fixedly connected with an electric slide 3 93. The slider of the electric slide 3 93 is fixedly connected with an electric push rod 3 94. The driving end of the electric push rod 3 94 is fixedly connected with a cooling table 95.

[0036] Specifically, the cooling platform 95 is driven by the electric slide 93 to move to the drop point of the inner ring, so that the inner ring can be supported when the inner ring falls to avoid collision when the inner ring falls. Then the electric push rod 94 is extended to drive the cooling platform 95 and the inner ring to descend to the inside of the cooling water tank 91, and the inner ring is cooled by the cooling water inside the cooling water tank 91, so as to quickly cool the inner ring.

[0037] Please refer to the attached Figure 7 Two baffles 96 are fixedly connected to the upper surface of the cooling water tank 91 , and a conveyor belt 10 is installed on one side of the cooling water tank 91 .

[0038] Specifically, the baffles 96 are arranged on both sides of the falling point of the inner ring, and intercept the inner ring when it falls, so as to prevent the inner ring from falling off the baffles 96.

[0039] Please refer to the attached Figure 8 The cooling table 95 includes a fixed plate 951, one end of which is rotatably connected to a perforated plate 952 via a torsion spring shaft, a lower side wall of the fixed plate 951 is fixedly connected to a limiting protrusion 953, and a lower surface of the perforated plate 952 is provided with a limiting groove.

[0040] Specifically, the orifice plate 952 uses the torsion force of the torsion spring shaft to make the limiting groove press against the limiting protrusion 953, so that the orifice plate 952 maintains a horizontal distribution, and the inner ring falls to the top of the orifice plate 952 when it falls.

[0041] Please refer to the attached Figure 7 A material removal piece 11 is fixedly connected to the upper part of the frame of the conveyor belt 10, and the material removal piece 11 is set to be T-shaped.

[0042] Specifically, after cooling is completed, the electric push rod three 94 contracts to drive the cooling table 95 to move out of the water tank, and then the cooling table 95 is moved to the top of the blanking piece 11 through the electric slide table three 93, and the electric push rod three 94 is controlled to extend to make the cooling table 95 descend. When the cooling table 95 descends, the blanking piece 11 presses against the orifice plate 952, causing the orifice plate 952 to tilt, so that the cooled inner ring slides down from the cooling table 95 to the conveyor belt 10, and is finally transported away by the conveyor belt 10, thereby realizing the automatic transportation of the inner ring.
