Description

Technical Field

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

[0002] In the field of mechanical manufacturing, bearings are increasingly widely used. A bearing is a component used to determine the relative movement position of a rotating shaft and other parts, and plays a role of supporting or guiding. It is a component that bears gravity and transmits power. The main parts of a bearing are composed of inner and outer rings, rolling elements and a cage. The quality of the inner and outer rings largely determines the service life. The forging of bearing rings is a relatively typical type of processing in mechanical forging. The vast majority of bearing rings are made of high-carbon chromium bearing steel (GCr15 and GCr15SiMn, and ZGCr15 and ZGCr15SiMn). The hardness of its parts is as follows: the rings made of GCr15 and ZGCr15 materials are HRc61 - 65; the rings made of GCr15SiMn and ZGCr15SiMn materials are HRc60 - 64; the bearings made of high-carbon chromium bearing steel are generally applicable to a working temperature range of -40 to 130 °C, and the oil and grease lubrication is normal.

[0003] During the production of existing inner bearing rings, it is necessary for workers to place the heated billets in different forging equipment multiple times, with low automation, seriously affecting production efficiency. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a safe production forging production line for protecting the loading and unloading of bearing parts, which solves the problem of low automation caused by workers placing the heated billets in different forging equipment.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: A safe production forging production line for protecting the loading and unloading of bearing parts includes a billet conveyor belt. A number of positioning chucks are provided on the surface of the billet conveyor belt. The positioning chuck is composed of two arc-shaped parts. The positioning chuck is used to place the billets. One side of the billet conveyor belt is provided with a processing table. One side of the processing table is provided with a support frame I. A number of cylinders are fixedly connected to the inner top wall of the support frame I. The driving end of the cylinder is fixedly connected with a forging round head. An electric slide table I is fixedly connected to the inner top wall of the support frame I. A transfer assembly is installed on the surface of the processing table. The transfer assembly includes an electric slide table II and a fixture. The lower surface of the electric slide table II is fixedly connected to the upper surface of the processing table. The slider of the electric slide table II is fixedly connected with a connecting column. One end of the connecting column is fixedly connected with a forging limit sleeve. The fixture is used to move the billets from the positioning chuck to the forging limit sleeve.

[0006] Preferably, the fixture includes an electric push rod I, the top end of the electric push rod I is fixedly connected to the slider of the electric slide I, and the driving end of the electric push rod I is fixedly connected with a connecting cover.

[0007] Preferably, electric push rods II are symmetrically and fixedly connected to the lower side of the connecting cover, and clamping blocks are fixedly connected to the driving ends of the electric push rods II.

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

[0009] Preferably, the forging limiting sleeve includes a semi-ring body I and a semi-ring body II, and spring telescopic rods are respectively fixedly connected to both sides of the semi-ring body I and the semi-ring body II.

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

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

[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 includes a fixing plate, one end of the fixing plate is rotationally connected to a perforated plate through a torsion spring rotating shaft, a limiting protrusion is fixedly connected to the lower side wall of the fixing plate, and a limiting groove is formed on the lower surface of the perforated plate.

[0014] Preferably, a blanking part is fixedly connected above the frame of the conveyor belt, and the blanking part is T-shaped.

[0015] Working principle: Place the heated inner ring blank inside the positioning collar for positioning, and convey the positioning collar containing the inner ring blank to the lower part of the fixture through the blank conveyor belt. Transfer the blank to the inside of the forging limiting sleeve through the fixture, and drive the forging limiting sleeve to move successively below the three groups of cylinders through the electric slide II for forging, gradually forging the inner ring blank into an inner ring with a conforming size, without manual operation, improving the safety during forging, with a high degree of automation and effectively increasing the production efficiency.

[0016] When transferring the blank by the fixture, the electric sliding table 1 drives the fixture to move below the positioning bushing. Control the electric push rod 1 to extend so that the connecting cover covers the outside of the positioning bushing. Run the electric push rod 2 to extend so that the clamping block abuts against the blank to achieve clamping and fixing. Then, the electric push rod 1 contracts to drive the blank to rise. Then, the electric sliding table 1 moves the blank above the forging limit sleeve, and the electric push rod 1 extends again so that the blank drops into the forging limit sleeve. Finally, control the electric push rod 2 to contract, and the blank can be moved from the positioning bushing to the forging limit sleeve to realize the automatic transfer of the blank.

[0017] After the blank forging is completed, the electric sliding table 2 drives the forging limit sleeve to move to the inclined section. At this time, the extrusion force received by the semi-ring body 2 gradually decreases, and the semi-ring body 1 and the semi-ring body 2 gradually expand through the elastic force of the spring telescopic rod, so that the forged inner ring sleeve can fall off from the forging limit sleeve.

[0018] The electric sliding table 3 drives the cooling table to move to the dropping point of the inner ring sleeve, so that the cooling table can carry the inner ring sleeve when the inner ring sleeve drops, avoiding bumps when the inner ring sleeve falls. Then, the electric push rod 3 extends, driving the cooling table and the inner ring sleeve to drop into the cooling water tank. The cooling water in the cooling water tank is used to cool the inner ring sleeve by water cooling, so as to quickly cool down the inner ring sleeve.

[0019] After cooling is completed, the electric push rod 3 contracts to drive the cooling table to move out of the water tank. Then, the electric sliding table 3 moves the cooling table above the blanking part. When controlling the electric push rod 3 to extend to make the cooling table drop, when the cooling table drops, the blanking part abuts against the orifice plate, making the orifice plate tilt, so that the cooled inner ring sleeve slides down from the cooling table to the conveyor belt and is finally conveyed away by the conveyor belt to realize the automatic transportation of the inner ring sleeve.

[0020] The present invention provides a safe production forging production line for the loading and unloading protection of bearing parts. It has the following beneficial effects:

[0021] 1. The present invention drives the forging limit sleeve to move below the three groups of cylinders in turn for forging by the electric sliding table 2, gradually forging the inner ring sleeve blank into an inner ring sleeve with a conforming size, without manual operation, improving the safety during forging, with a high degree of automation and effectively increasing the production efficiency.

[0022] 2. After the forging of the present invention is completed, the electric sliding table 2 drives the forging limit sleeve to move to the inclined section. At this time, the extrusion force received by the semi-ring body 2 gradually decreases, and the semi-ring body 1 and the semi-ring body 2 gradually expand through the elastic force of the spring telescopic rod, so that the forged inner ring sleeve can fall off from the forging limit sleeve.

[0023] 3. The present invention drives the cooling table to move to the dropping point of the inner ring by means of the electric slide table III, so that the inner ring can be carried when it drops, avoiding bumps when the inner ring falls. Subsequently, the electric push rod III extends, driving the cooling table and the inner ring to descend into the cooling water tank, and cooling the inner ring by the cooling water inside the cooling water tank, thereby quickly cooling the inner ring.

[0024] 4. The present invention moves the cooling table above the blanking part by means of the electric slide table III. When controlling the electric push rod III to extend to lower the cooling table, when the cooling table descends, the blanking part abuts against the orifice plate, causing the orifice plate to tilt, so that the cooled inner ring slides down from the cooling table to the conveyor belt and is finally conveyed away by the conveyor belt, realizing the automatic transportation of the inner ring.

Detailed implementation mode

[0034] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0035] Please refer to the attached Figure 1 - attached Figure 3 As shown in the figure, the present invention provides a safe production forging production line for the loading and unloading protection of bearing parts, including a blank conveyor belt 1. A plurality of positioning sleeves 2 are provided on the surface of the blank conveyor belt 1. The positioning sleeve 2 is composed of two arc-shaped parts. The positioning sleeve 2 is used to place the blank. A processing table 3 is installed on one side of the blank conveyor belt 1. A first support frame 4 is installed on one side of the processing table 3. A plurality of cylinders 5 are fixedly connected to the inner top wall of the first support frame 4. The driving end of the cylinder 5 is fixedly connected to a forging round head 6. A first electric sliding table 7 is fixedly connected to the inner top wall of the first support frame 4. A transfer assembly 8 is installed on the surface of the processing table 3. The transfer assembly 8 includes a second electric sliding table 81 and a fixture 84. The lower surface of the second electric sliding table 81 is fixedly connected to the upper surface of the processing table 3. The slider of the second electric sliding table 81 is fixedly connected to a connecting column 82. One end of the connecting column 82 is fixedly connected to a forging limiting sleeve 83. The fixture 84 is used to move the blank from the positioning sleeve 2 to the forging limiting sleeve 83. The sizes of the plurality of forging round heads 6 gradually increase according to the conveying direction of the blank, and the diameter of the last forging round head 6 is equal to the inner diameter of the inner ring sleeve.

[0036] 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 to form an inner ring of 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.

[0037] Please see 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.

[0038] 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 clamping 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.

[0039] Please see the attached Figure 3 The outer wall of the connecting column 82 is fixedly connected with an intercepting plate 85.

[0040] 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.

[0041] Please see the attached Figure 5 The forging limit sleeve 83 includes a semi-ring body 1 831 and a semi-ring body 2 832, and the two sides of the semi-ring body 1 831 and the semi-ring body 2 832 are respectively fixedly connected with a spring telescopic rod 833. 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.

[0042] Specifically, the straight section 861 and the connecting column 82 cooperate to tightly press against the first half-ring body 831 and the second half-ring body 832, so that the forging limit sleeve 83 is closed for forging the blank. After the blank forging is completed, the electric slide table 81 drives the forging limit sleeve 83 to move to the inclined section 862. At this time, the extrusion force received by the second half-ring body 832 gradually decreases, and the first half-ring body 831 and the second half-ring body 832 gradually expand through 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.

[0043] Please refer to the appendix Figure 6 - appendix Figure 7 On one side of the processing table 3, a cooling assembly 9 is installed. The cooling assembly 9 includes a cooling water tank 91 and a second support frame 92. Both the cooling water tank 91 and the second support frame 92 are fixed on the ground. A third electric slide table 93 is fixedly connected to the inner top wall of the second support frame 92. A third electric push rod 94 is fixedly connected to the slider of the third electric slide table 93. The driving end of the third electric push rod 94 is fixedly connected to a cooling table 95.

[0044] Specifically, the third electric slide table 93 drives the cooling table 95 to move to the dropping point of the inner ring, so that the inner ring can be carried when it drops, avoiding bumps when the inner ring falls. Subsequently, the third electric push rod 94 extends, driving the cooling table 95 and the inner ring to descend into the interior of the cooling water tank 91, and cooling the inner ring by the cooling water inside the cooling water tank 91, so as to quickly cool down the inner ring.

[0045] Please refer to the appendix Figure 7 On the upper surface of the cooling water tank 91, two baffles 96 are fixedly connected, and a conveyor belt 10 is installed on one side of the cooling water tank 91.

[0046] Specifically, the baffles 96 are arranged on both sides of the dropping point of the inner ring to intercept the inner ring when it drops, avoiding the inner ring falling off from the baffles 96.

[0047] Please refer to the appendix Figure 8 The cooling table 95 includes a fixing plate 951. One end of the fixing plate 951 is rotatably connected to a hole plate 952 through a torsion spring rotating shaft. A limiting protrusion 953 is fixedly connected to the lower side wall of the fixing plate 951. A limiting groove is formed on the lower surface of the hole plate 952.

[0048] Specifically, due to the torsion of the torsion spring rotating shaft, the limiting groove of the hole plate 952 abuts against the limiting protrusion 953, so that the hole plate 952 maintains a horizontal distribution, and the inner ring drops above the hole plate 952 when it drops.

[0049] Please refer to the appendix Figure 7 Above the frame of the conveyor belt 10, a blanking part 11 is fixedly connected, and the blanking part 11 is T-shaped.

[0050] 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. Subsequently, the electric sliding table three 93 moves the cooling table 95 above the blanking part 11. When controlling the electric push rod three 94 to extend to lower the cooling table 95, when the cooling table 95 descends, the blanking part 11 abuts against the orifice plate 952, causing the orifice plate 952 to tilt. As a result, the cooled inner ring slides down from the cooling table 95 onto the conveyor belt 10 and is finally conveyed away by the conveyor belt 10, realizing the automatic transportation of the inner ring.

[0051] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
