Description

Technical Field

[0001] This invention belongs to the field of rail pressure plate production technology, specifically, it relates to a rail pressure plate pressing device. Background Technology

[0002] Rail clamping plates are accessories used to clamp and fix rails to I-beams, concrete beams, or the ground. They are also known as crane clamping plates, overhead crane clamping plates, track clamping plates, crane rail clamping plates, etc. The clamping plate material is generally made of Q235, cast steel, etc., through hot forging process, and is usually fastened with hexagonal bolts or pre-embedded bolts.

[0003] During the production process, the raw materials are first cut into billets of fixed size according to the dimensions. Then, the oxide scale, rust, oil mist and other impurities on the surface of the billets are cleaned. After cleaning, they are sent to a heating furnace and heated to the hot forging temperature (generally 1100 degrees Celsius to 1250 degrees Celsius for cast steel). Then, they are sent to the pre-forging station to perform preliminary shaping of the billets. Then, they are transferred to the final forging die for high-pressure forming to make the complete shape of the rail pressure plate. Then, the flash of the workpiece is removed. After the workpiece cools down, it can be heat treated and surface strengthened. Then, bolt holes are machined by drilling. After quality inspection, it can be packaged and stored.

[0004] However, in actual production using existing technologies, the process of transporting heated billets to the pre-forging and final forging stations is often hampered by the fact that these stations are typically independently arranged. This means that the transfer of billets between stations requires manual labor or simple robotic arms. This operation is not only labor-intensive but also poses a safety hazard of high-temperature burns. Furthermore, this transfer method takes a considerable amount of time. During the transfer process, relying solely on the residual heat of the billet itself to maintain the temperature can easily lead to localized rapid cooling and sudden temperature drops, resulting in poor plasticity and insufficient fluidity of the billet metal. This can cause defects such as incomplete filling of irregularly shaped parts and cracking of the workpiece during forging, ultimately affecting the product forming quality. Summary of the Invention

[0005] The purpose of this invention is to provide a rail pressing plate pressing device, which solves the technical problem in related technologies where the billet relies solely on its own residual heat to maintain the temperature during the transfer process, which can easily lead to localized rapid cooling and a sudden drop in temperature during long-term transfer, resulting in poor metal plasticity and insufficient fluidity of the billet, thus affecting the product forming quality.

[0029] like Figures 1 to 5 As shown, a rail pressing device according to an embodiment of the present invention is illustrated, including a base frame 1, a first bearing frame 2 and a second bearing frame 3 fixedly installed on the side of the base frame 1, and a support frame 4, a forging assembly and a heat-insulating feeding assembly. The support frame 4 is fixedly installed on the base frame 1, and a feeding turntable 5 is rotatably installed inside the support frame 4. Forging assemblies are installed on both the first bearing frame 2 and the second bearing frame 3 for forging heated billets. The forging assembly includes a primary forging frame 6, a precision forging frame 7 and a forging pressing part. The primary forging frame 6 is fixedly installed on the first bearing frame 2, and the precision forging frame 7 is fixedly installed on the second bearing frame 3. Forging pressing parts are installed on both the primary forging frame 6 and the precision forging frame 7 for forging billets moved into the forging position of the primary forging frame 6 or the forging position of the precision forging frame 7.

[0030] When processing rail pressure plates, the raw materials are first cut into blanks of fixed dimensions. Then, the blanks are cleaned and sent to a heating furnace to be heated to the hot forging temperature. Finally, the blanks are... Figure 1As shown by arrow A, the billet is fed into the corresponding insulated feeding assembly. At this point, the feeding turntable 5 is driven to rotate, conveying the billet to the initial forging stand 6. It is then fed into the forging section within the initial forging stand 6 for pressing, achieving preliminary shaping. The preliminarily shaped billet is then placed back into the insulated feeding assembly. The feeding turntable 5 is driven to rotate again, moving the preliminarily shaped billet to the precision forging stand 7. It is then pushed into the forging section within the precision forging stand 7 for high-pressure forming, completing the shape of the rail plate. Finally, the finished product is placed back into the insulated feeding assembly, and the feeding turntable 5 is driven to rotate again until the finished product is conveyed to the... Figure 1 The finished product can be conveyed out at the feeding position indicated by the arrow in direction B.

[0031] Furthermore, the flash of the workpiece is removed, and after the workpiece cools down, it can be subjected to heat treatment and surface strengthening treatment. Then, bolt holes are machined by drilling, thus completing the entire processing of the rail pressure plate.

[0032] It should be noted that the heat-insulating feeding assembly needs to be preheated to a specified temperature before operation, so as to keep the temperature of the preheated billet warm and avoid the generation of a large amount of oxide scale due to the billet temperature dropping too quickly, which would affect the forging process.

[0033] The forging section described above includes a sliding frame 8, a first driving component 9, an upper die 10, and a lower die 11. Sliding frames 8 are slidably mounted on both the primary forging frame 6 and the precision forging frame 7. First driving components 9 are fixedly mounted on both the primary forging frame 6 and the precision forging frame 7. The output end of the first driving component 9 is fixedly connected to the sliding frame 8. An upper die 10 is mounted on each sliding frame 8, and a lower die 11 is provided at the lower part of each upper die 10. The two lower dies 11 are respectively mounted on the primary forging frame 6 and the precision forging frame 7. The section also includes a base plate 12 and a second driving component 13. The base plate 12 is slidably mounted inside each lower die 11. The second driving component 13 is fixedly mounted at the bottom of both the primary forging frame 6 and the precision forging frame 7. The output end of the second driving component 13 is fixedly connected to the base plate 12. After the upper die 10 and the lower die 11 are closed, a pressing cavity is formed between the upper die 10 and the base plate 12. Preferably, the first driving component 9 and the second driving component 13 are in the form of hydraulic cylinders.

[0034] The upper die 10 and lower die 11 on the primary forging frame 6 are primary forging dies, and the upper die 10 and lower die 11 on the precision forging frame 7 are precision forging dies. When the billet needs to be transported to the position of the primary forging frame 6 and then sent into the upper die 10 and lower die 11 inside the primary forging frame 6 for pressing, the second drive component 13 is first activated to push the base plate 12 upward until the base plate 12 and the bottom surface of the billet are on the same plane. Then the billet is sent onto the corresponding base plate 12. After adjusting the position of the billet, the second drive component 13 can be retracted. At this time, the base plate 12 is located on the inner bottom wall of the lower die 11. Then the first drive component 9 on the primary forging frame 6 is activated to push the upper die 10 on the sliding frame 8 to move until the corresponding upper die 10 and lower die 11 are closed. Then the billet can be pressed by pressure to perform the primary forging operation.

[0035] After the initial forging is completed, the first drive component 9 is retracted to remove the upper die 10. Then, the second drive component 13 is activated to move the base plate 12, moving the initially forged billet out of the lower die 11 and feeding it back into the feeding turntable 5. As the feeding turntable 5 rotates, it is fed to the position of the precision forging frame 7, and then pressed between the upper die 10 and the lower die 11 inside the precision forging frame 7. The above operation steps are repeated for the upper die 10 and the lower die 11 in the precision forging frame 7. The pressure of the mold closing between the upper die 10 and the lower die 11 shapes the billet, thus obtaining the finished product. The finished product is then fed back into the feeding turntable 5 and transported to the... Figure 1 The finished product can be conveyed out at the feeding position indicated by the arrow in direction B.

[0036] The feeding turntable 5 is equipped with a heat-insulating feeding assembly, which is used to keep the heated billet warm and sequentially feed it to the primary forging station and the precision forging station, and finally transport the pressed finished product out. The heat-insulating feeding assembly includes a sliding cavity 14, a third drive component 16, a sixth drive component 27, and a heating section. Several sliding cavities 14 are circumferentially and equally angled on the feeding turntable 5. A material rack 15 is slidably installed inside each sliding cavity 14 along the diameter of the feeding turntable 5. Each material rack 15 is provided with a heat-insulating layer 17. Several third drive components 16 are fixedly installed circumferentially inside the feeding turntable 5. Each component 16 corresponds to one of several material racks 15. The output end of the third drive component 16 is fixedly connected to the material rack 15. Each material rack 15 is equipped with a sixth drive component 27. The output end of the sixth drive component 27 is located inside the material rack 15 and slides in cooperation with the material rack 15. The third drive component 16 and the sixth drive component 27 are preferably electric cylinders and need to be heat-insulated to ensure that the high temperature of preheating will not affect the third drive component 16 and the sixth drive component 27. Each sliding cavity 14 is equipped with a heating element to adjust and maintain the temperature of the internal area of ​​the material rack 15.

[0037] When conveying the billet, first turn on the heating section, then transfer the preheated billet from... Figure 1 The material is fed into the corresponding material rack 15 by the arrow A shown. It is kept warm by the insulation layer 17. At this time, the feeding turntable 5 is driven to rotate, and the corresponding material rack 15 is moved to the loading position. After the bottom plate 12 is moved to the same plane as the bottom surface of the billet, the third drive component 16 is activated to push the material rack 15 to move in the sliding cavity 14 until the front end of the material rack 15 contacts the bottom plate 12. Then the sixth drive component 27 is activated. The output end of the sixth drive component 27 abuts against the billet and pushes it onto the bottom plate 12. Then the third drive component 16 and the sixth drive component 27 are retracted to allow it to enter the forging process.

[0038] It should be added that the output end of the sixth drive component 27 that contacts the billet is provided with a heat insulation structure such as a heat insulation pad, which is used to reduce the temperature of the billet being transferred to the output end of the sixth drive component 27 due to contact, thereby keeping the billet at a suitable forging temperature for a long time.

[0039] The heating section, as described above, includes a heat-conducting plate 18 and a heater 19. A heat-conducting plate 18 is fixedly installed at the bottom of each material rack 15, and a heater 19 is provided at the bottom of each heat-conducting plate 18. The heating end of the heater 19 slides against the heat-conducting plate 18. The heater 19 is fixedly installed inside the sliding cavity 14. The section also includes a fourth driving component 20, a fifth driving component 21, and an adjusting frame 22. Two fourth driving components 20 are symmetrically arranged on the primary forging frame 6. The fourth driving components 20 located on both sides of the primary forging frame 6 are both installed on the first bearing frame 2. Two fourth drive components 20 are symmetrically arranged on the precision forging frame 7. The fourth drive components 20 located on both sides of the precision forging frame 7 are installed on the second bearing frame 3. The second bearing frame 3 and the first bearing frame 2 are both equipped with fifth drive components 21. The fifth drive components 21 are located on the side of the corresponding sliding frame 8 away from the feeding turntable 5. The fourth drive components 20 and the fifth drive components 21 are preferably electric cylinders. The output end of each fourth drive component 20 and the output end of each fifth drive component 21 are fixedly installed with an adjustment frame 22.

[0040] It should be added that the heater 19 adopts a resistance heating device, which can heat the heat conduction plate 18 to about 500 degrees Celsius during operation, so that the inside of the material rack 15 is in a high-temperature environment. This is used to avoid local cooling and sudden temperature drop when conveying high-temperature billets, and to ensure that the overall temperature of the billet is maintained in a stable hot forging plastic range during the process of conveying the billet to the primary forging station and the fine forging station, so as to ensure the metal fluidity and forging quality.

[0041] Before conveying the billet, the heater 19 is turned on to heat the heat-conducting plate 18, thereby maintaining a high temperature inside the material rack 15. This prevents the billet from cooling down too quickly during conveying, which could lead to insufficient fluidity during forging and improves the stability of the pressing process.

[0042] With the fourth drive component 20 in place, after the blank is transferred to the base plate 12, the fourth drive component 20 can be activated, and the position of the blank on the base plate 12 can be adjusted by the adjustment frame 22, so that the blank can be placed into the lower mold 11.

[0043] When it is necessary to put the formed blank back into the corresponding material rack 15, the material rack 15 is first moved to the receiving position, and then the fifth drive component 21 is turned on. The formed blank can then be sent back into the corresponding material rack 15 through the setting of the adjustment frame 22.

[0044] The support frame 4 has a mounting frame 23 and a drive motor 26 fixedly installed at its bottom. The mounting frame 23 has a drive gear 24 and a driven gear 25 rotatably installed inside it. The drive gear 24 meshes with the driven gear 25. The driven gear 25 is coaxially and fixedly connected to the feeding turntable 5. The drive motor 26 is fixedly installed at the bottom of the mounting frame 23. The output end of the drive motor 26 is fixedly connected to the drive gear 24.

[0045] When it is necessary to drive the feeding turntable 5 to rotate, the drive motor 26 is turned on. The drive motor 26 drives the drive gear 24 to rotate, which in turn drives the driven gear 25 to rotate, thereby driving the feeding turntable 5 to rotate.

[0046] The working principle or usage process of this invention is as follows: First, the raw materials are cut into blanks of a fixed size. Then, the blanks are cleaned and sent into the heating furnace to be heated to the hot forging temperature. Then, the heater 19 is turned on to heat the heat conduction plate 18, so that the inside of the material rack 15 is kept at a high temperature. This avoids the blanks from cooling down too quickly during the conveying process, which would cause insufficient fluidity during forging and improves the stability of the pressing process.

[0047] The blank is from Figure 1 As shown by arrow A, the material is fed into the corresponding placement rack 15. At this time, the drive motor 26 is turned on, which drives the drive gear 24 to rotate, which in turn drives the driven gear 25 to rotate, thereby driving the feeding turntable 5 to rotate until the billet is conveyed to the position of the primary forging frame 6. Then, the second drive component 13 is activated to push the base plate 12 upward until the base plate 12 and the bottom surface of the billet are on the same plane. Then, the third drive component 16 is activated to push the placement rack 15 into the sliding cavity 14. Move the material rack 15 until its front end contacts the base plate 12. Then, activate the sixth drive component 27. The output end of the sixth drive component 27 presses against the blank and pushes it onto the base plate 12. Then, retract the third drive component 16 and the sixth drive component 27. After the blank is transferred to the base plate 12, activate the fourth drive component 20. Adjust the position of the blank on the base plate 12 using the adjustment frame 22 to facilitate placing the blank into the lower mold 11.

[0048] After adjusting the position of the billet, the second drive component 13 can be retracted. At this time, the base plate 12 is located on the inner bottom wall of the lower mold 11. Then, the first drive component 9 on the initial forging frame 6 is opened, thereby pushing the upper mold 10 on the sliding frame 8 to move until the corresponding upper mold 10 and lower mold 11 are closed. Then, the billet can be pressed by pressure to perform the initial forging operation and make it initially formed. Then, the second drive component 13 is opened to push the billet out of the lower mold 11 and move the material rack 15 to the receiving position. Then, the fifth drive component 21 is opened, and the formed billet can be sent back to the corresponding material rack 15 through the setting of the adjustment frame 22.

[0049] At this point, the feeding turntable 5 is driven to rotate again, moving the pre-formed billet to the position of the precision forging frame 7. It is then fed into the upper die 10 and lower die 11 within the precision forging frame 7 for pressing. The above operation steps are repeated on the upper die 10 and lower die 11 within the precision forging frame 7. The pressure of the closing molds between the upper die 10 and lower die 11 shapes the billet, thus obtaining the finished product. The finished product is then returned to the feeding turntable 5 and transported to... Figure 1 The finished product can be conveyed out at the blanking position indicated by arrow B, thus completing the forging process of the rail pressure plate.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
