Technical Field
[0001] This invention relates to the field of forging press technology, and in particular to a 10,000-ton-class free forging hydraulic press. Background Technology
[0002] In the design and manufacturing process of offshore wind turbines, the processing standards for key forgings such as flanges and cylinders are more stringent and precise than those for other types of industrial products. These forgings not only need to possess extremely high strength and corrosion resistance to meet the challenges of the harsh marine environment, but also need to ensure dimensional accuracy and shape complexity to ensure the safe and stable operation of the wind turbine.
[0003] However, most forging presses currently on the market can only handle medium-sized and relatively simple-shaped parts. They often fall short when dealing with the production needs of large, complex, and irregularly shaped parts. These machines have certain limitations in terms of processing capacity, precision control, and adaptability, and cannot meet the demand for high-performance forgings in offshore wind turbines.

[0019] A further improvement of the present invention, a 10,000-ton free forging hydraulic press, is that the two lower beam blocks are provided with second positioning keys, and the two lower beam blocks are connected by interlocking the second positioning keys.
[0020] A further improvement of the present invention, a 10,000-ton free forging hydraulic press, is that the slider has a sliding hole corresponding to the position of the support column, and the support column is slidably disposed in the sliding hole; the top of the slider has a plunger mounting hole, the main cylinder has a plunger rod, and the plunger rod is connected to the plunger mounting hole.

The following embodiments are used to illustrate this invention but should not be used to limit the scope of this invention.
[0038] The following is combined Figure 1 and Figure 2 The present invention describes a 10,000-ton-class free forging hydraulic press, comprising:

[0040] Slider 3, which is slidably disposed on the support column 5 and located between the combined upper crossbeam 1 and the combined lower crossbeam 6;
[0041] Main hydraulic cylinder 2 is mounted on the upper crossbeam and is driven by the slider 3;
[0042] Mold 4, which is detachably connected to the bottom surface of slider 3 via an upper anvil quick-change device;
[0043] A mobile worktable device is installed on the top surface of the combined lower crossbeam 6. The mobile worktable device includes a push cylinder 73, a mobile stage 71 connected to the push cylinder 73, and a pressure mold 7 disposed on the mobile stage 71.
[0044] Preferably, the 10,000-ton free forging hydraulic press in this invention is a 22,000-class free forging hydraulic press.
[0045] Preferably, the combined lower crossbeam 6 is fixed to the foundation by concrete, and the side of the combined lower crossbeam 6 is provided with a hydraulic power system 10 and an electrical system 11 to control the main cylinder 2, the push cylinder 73 and the quick-change cylinder 41.
[0046] In a preferred embodiment of the present invention, a 10,000-ton-class free forging hydraulic press, such as... Figure 4As shown, the combined upper beam 1 includes two upper beam blocks 101 connected together and upper tie rods 102 passing through and connecting the two upper beam blocks 101; three sets of upper tie rods 102 are provided at both ends of the upper beam blocks 101, two sets of upper tie rods 102 are provided at the top of the upper beam blocks 101, two sets of upper tie rods 102 are provided at the bottom of the upper beam blocks 101, and four sets of upper tie rods 102 are passed through the middle of the upper beam blocks 101; each upper beam block 101 is provided with two support columns 5; a cylinder connecting groove 103 is opened in the middle of the upper beam blocks 101, and the cylinder connecting grooves 103 of the two upper beam blocks 101 are connected together, and the main cylinder 2 is connected to the cylinder connecting grooves 103 of the two upper beam blocks 101 respectively.
[0047] Preferably, the upper beam block 101 has four column connection holes corresponding to the position of each column 5. The column connection holes are used to pass through the connecting columns 5 so that the columns 5 can stably support the upper beam block 101.
[0048] Preferably, the top and bottom of the upper beam block 101 are provided with a first ear plate and a first guide cylinder connected to the first ear plate, corresponding to the position of the upper pull rod 102, and the upper pull rod 102 passes through the first ear plate and the first guide cylinder.
[0049] Preferably, of the three sets of upper tie rods 102 at both ends of the upper beam block 101, two sets are located near the top and one set is located near the bottom; two second ear plates and a second guide cylinder connected between the two second ear plates are provided at the end of the upper beam block 101 near the top, and the two sets of upper tie rods 102 at the top are passed through and connected to the second guide cylinder of the second ear plates; a third guide cylinder is provided at the end of the upper beam block 101 near the bottom, and the one set of upper tie rods 102 at the bottom is passed through and connected to the third guide cylinder.
[0050] Preferably, the arrangement of the second and third guide cylinders makes the upper tie rod 102 more stable during installation, reducing connection instability caused by swaying or deviation. Furthermore, the connection structure between the second ear plate and the second guide cylinder enhances the structural strength of the end of the upper beam block 101, improving the overall stability and safety of the equipment.
[0051] Specifically, the upper beam block 101 is equipped with a first positioning key 104. Two upper beam blocks 101 are connected by interlocking via the first positioning key 104. The first positioning key 104 ensures the accuracy and stability of the upper beam blocks 101 during interlocking, effectively avoiding connection problems caused by misalignment. Furthermore, the first positioning key 104 also serves as a guide, enabling the two upper beam blocks 101 to be smoothly and quickly positioned and locked during the interlocking process, improving installation efficiency and accuracy.
[0052] Furthermore, such as Figure 6As shown, the combined lower crossbeam 6 includes two lower beam blocks 61 connected to each other, pull rods 62 passing through and connecting the two lower beam blocks 61, and a base 63 fixedly connected to the two lower beam blocks 61. Two sets of pull rods 62 are provided at both ends of the lower beam blocks 61, and four sets of pull rods 62 are provided at the bottom of the lower beam blocks 61. The base 63 is U-shaped and includes two side beams arranged opposite each other and a guide plate connected to the two side beams. The two side beams are respectively attached to the two lower beam blocks 61, and the guide plate is located on the top surface of the two lower beam blocks 61. Eight sets of pull rods 62 are passed between the two side beams and the two lower beam blocks 61. The movable worktable device is installed on the top surface of the guide plate, and each lower beam block 61 is provided with two support columns 5.
[0053] Preferably, each lower beam block 61 is provided with two support columns 5, which provide additional support and ensure that the lower beam block 61 will not deform or be damaged when subjected to heavy loads for a long time.
[0054] Specifically, the lower beam block 61 has two third ear plates at its end and a third guide cylinder connected between the two third ear plates, and the pull rod 62 passes through the third ear plates and the third guide cylinder.
[0055] Specifically, each of the two lower beam blocks 61 is equipped with a second positioning key 64, which is used to align the two lower beam blocks 61 together. The second positioning key 64 not only enhances the connection stability between the two lower beam blocks 61 but also ensures the accuracy of the alignment, allowing the two lower beam blocks 61 to form a unified structure after assembly, jointly bearing the enormous pressure generated by the hydraulic press during operation. The second positioning key 64 also prevents relative displacement of the two lower beam blocks 61 during long-term use, thereby extending the service life of the combined lower crossbeam 6. During the alignment process, the operator only needs to align and insert the second positioning key 64 of the two lower beam blocks 61 to achieve a quick and stable connection, greatly improving assembly efficiency.
[0056] Specifically, the guide plate has a positioning groove, and the bottom of the moving guide rail has a positioning block. The positioning block engages with the positioning groove to connect the moving guide rail to the guide plate, enhancing the stability of the connection between the moving guide rail and the guide plate. The cooperation between the positioning groove and the positioning block ensures the precise positioning of the moving guide rail on the guide plate, avoiding operational instability caused by offset or shaking. At the same time, this engaging connection method facilitates disassembly and maintenance, reducing the difficulty and cost of later maintenance.
[0057] Preferably, the lower beam block 61 has a lower support hole at the position corresponding to the column 5, and the column 5 is inserted into the lower support hole to realize the connection between the column 5 and the lower beam block 61.
[0058] Furthermore, such as Figure 5As shown, the slider 3 has a sliding hole 31 at the position of the support column 5, and the support column 5 is slidably mounted in the sliding hole 31; the top of the slider 3 has a plunger mounting hole 32, and the main cylinder 2 has a plunger rod, which is connected to the plunger mounting hole 32.
[0059] Specifically, a guide device 8 is provided between the slider 3 and the support column 5. The slider 3 has a guide connection hole at the position corresponding to the guide device 8. The guide device 8 is a hydraulic rod or telescopic rod connected to the guide connection hole and the support column 5.
[0060] Furthermore, the bottom of the slider 3 is provided with an upper pad 12, and the mold 4 is detachably connected to the bottom of the upper pad 12 via an upper anvil quick-change device.
[0061] Specifically, such as Figure 3 As shown, the upper pad 12 has a first insertion hole and a second insertion hole. The first insertion hole extends horizontally, and the second insertion hole extends vertically. The first insertion hole and the second insertion hole are connected. The mold 4 has a third insertion hole at the position corresponding to the second insertion hole.
[0062] The quick-change device for the upper anvil includes a quick-change cylinder 41 installed on the side of the upper pad 12, a drive pin 46 connected to the quick-change cylinder 41, and a pin 47 passing through and connected to the second insertion hole and the third insertion hole. The pin 47 has a connection hole. The quick-change cylinder 41 drives the pin 46 to move so that the pin 46 is inserted into the connection hole, thereby fixing the mold 4 and the upper pad 12.
[0063] Specifically, the quick-change cylinder 41 is mounted on the side of the upper pad 12 via the mounting bracket 42. The quick-change plunger 43 of the quick-change cylinder 41 is connected to the pin 46 via the lock nut 45. A guide copper sleeve 44 is provided in the first insertion hole, and the quick-change plunger 43 and the pin 46 are located inside the guide copper sleeve 44.
[0064] Preferably, multiple sets of upper anvil quick-change devices are arranged at intervals along the periphery of slider 3.
[0065] Preferably, the quick-change anvil device makes mold 4 replacement more convenient and efficient. When mold 4 needs to be replaced, simply drive the pin 46 to move via the quick-change cylinder 41, causing the pin 46 to be pulled out of the connection hole, easily releasing the fixed connection between mold 4 and upper pad 12. Subsequently, the pin 47 can be removed from the combined channel of the first and second insertion holes to facilitate the replacement of the new mold 4. Then, the pin 47 is reinserted into the second and third insertion holes, and the quick-change cylinder 41 is used to re-drive the pin 46 into the connection hole of the pin 47, achieving quick mold 4 replacement. This design not only improves work efficiency but also helps reduce operational difficulty and labor costs.
[0066] Furthermore, the mobile worktable device also includes a mobile guide rail 74 installed on the combined lower crossbeam 6. The mobile table 71 is slidably mounted on the mobile guide rail 74. The mobile table is pushed along the mobile guide rail 74 by the push cylinder 73 to drive the pressing mold 7 to move, so that the pressing mold 7 corresponds to the mold 4, so as to make the material placed on the pressing mold 7 into a finished product. Then, the push cylinder 73 pushes the mobile table 71 to slide along the mobile guide rail 74 to drive the pressing mold 7 to move, thereby driving the finished product to move out of the machine frame.
[0067] Preferably, a movable mounting base 72 is provided on the top surface of the guide plate, and a movable guide rail 74 is mounted on the movable mounting base 72.
[0068] Preferably, a ladder 9 is provided on the side of the machine frame to facilitate staff to observe the production status of the products and carry out maintenance operations.
[0069] This invention's 10,000-ton-class free forging hydraulic press, by setting up a movable worktable device, can meet the needs of changing different pressure dies 7 and moving workpieces in and out, thereby increasing the range of forging applications for workpieces and the transportation efficiency of finished workpieces, and can meet the forging needs of large cylinders and plates; by setting up an upper anvil quick-change device, the efficiency of die 4 replacement is improved; by setting up a combined upper crossbeam 1 and a combined lower crossbeam 6, the load-bearing capacity of the fixed connection and the production efficiency are improved.
