Abstract

The present invention discloses a 10,000-ton winding free forging hydraulic press. The present invention designs a damper, an extrusion spring, and a rolling ball at the bottom of the column, and combines the arc-shaped buffer structure of the rolling groove to prevent the column from directly transmitting excessive impact force to the guide sleeve when the column is offset due to eccentric load, thereby improving the impact resistance and operating stability of the equipment when processing large castings. In addition, the rolling groove adopts an arc-shaped design, which cooperates with the rolling ball at the bottom of the column. When the column is offset, the rolling ball returns to the lowest point of the arc groove under the action of the extrusion spring, ensuring that the column always remains in a vertical state. The friction arc block is driven by an electric push rod to lock the column. When processing small castings with high precision requirements, the precise alignment of the upper and lower forging heads is guaranteed, and the processing accuracy of small workpieces is improved. At the same time, the feedback rod records the offset and impact force, which is convenient for workers to quickly identify problems and perform maintenance in time, avoiding equipment damage or reduced processing accuracy.

Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic presses, and more particularly to a 10,000-ton winding free forging hydraulic press. Background Art

[0002] A hydraulic open-die forging press is widely used for forging large workpieces. It uses a hydraulic system to drive a movable crossbeam and forging ram to apply pressure to the workpiece to complete the forging process. The column and guide sleeve in the press serve as key support components, primarily responsible for maintaining the stability of the movable crossbeam. However, due to the wide variety of workpieces, particularly when processing large castings with complex or irregular shapes, the column and guide sleeve are often subject to significant lateral forces or tilting moments, which can affect normal operation.

[0003] During the forging process, due to the irregular shape or offset of the center of gravity of the casting, it is easy to cause uneven distribution of the forging load, which will cause the column of the equipment to bear excessive lateral force or tilting torque, and then deform. This deformation will have a serious impact on the operating stability and forging accuracy of the equipment, especially when processing large castings. Due to the large volume and heavy mass of the workpiece, its center of gravity offset is more obvious, and the forging load distribution is more uneven, which will increase the offset of the column and transmit the excessive impact force to the guide sleeve. In the design of traditional hydraulic presses, there is a lack of effective buffering and reset structure between the column and the guide sleeve. The offset of the column will directly cause friction and impact on the guide assembly, resulting in serious wear and even damage to the guide sleeve. Although large castings have relatively low requirements for forging accuracy, the deformation and offset of the column will weaken the stability of the equipment, affect the forging effect, and even cause safety hazards.

[0004] When processing small castings, although the forging load is small, due to the high requirements for forging accuracy, any slight deformation or offset of the column will cause the motion trajectory of the movable beam to change, thereby affecting the alignment of the upper and lower forging heads, resulting in a decrease in the processing quality of the workpiece. Under long-term use, the repeated offset and deformation of the column will also reduce the overall operating performance of the equipment, making it difficult to meet the needs of high-precision small part forging. Therefore, traditional hydraulic presses are difficult to meet the stability requirements of large castings and the high-precision requirements of small castings at the same time, which limits the scope of application of the equipment and also reduces the reliability and durability of the equipment in long-term use.

[0005] Therefore, in response to the above technical problems, it is necessary to provide a 10,000-ton winding type free forging hydraulic press. Summary of the Invention

[0009] The limiting components are provided in multiple numbers, and the limiting components include a limiting cylinder, which is fixedly connected to the upper crossbeam, and the inner wall of the limiting cylinder is connected to the column through a universal joint; the feedback component includes a workbench, which is provided on the lower side of the upper crossbeam, a buffer table is installed at the bottom end of the workbench, and a lower forging head matching the upper forging head is installed at the top end of the workbench.

[0010] As a further improvement of the present invention, a damper is fixedly connected to the bottom end of the column, an extrusion spring is arranged outside the damper, and a moving block is fixedly connected to the bottom end of the damper, the two ends of the extrusion spring are respectively fixedly connected to the damper and the moving block, and a rolling ball is rotatably connected inside the moving block.

[0011] As a further improvement of the present invention, the inner wall of the limit assembly is inlaid with multiple evenly distributed limit dampers, one end of the limit damper is fixedly connected to the limit block, and multiple limit blocks are arranged outside the column, and multiple limit blocks are in contact with the outer wall of the column.

[0012] As a further improvement of the present invention, a plurality of evenly distributed rolling grooves are provided on the workbench, and the corresponding shape of the bottom end of the rolling groove is set to be an arc.

[0013] As a further improvement of the present invention, an electric push rod is embedded in the inner wall of the rolling groove, a friction arc block is fixedly connected to the output end of the electric push rod, and a friction pad is installed on the inner wall of the friction arc block.

[0014] As a further improvement of the present invention, a plurality of evenly distributed sealing grooves are provided on the inner wall of the rolling groove, a collision damper is slidably connected in the sealing groove, a collision block is fixedly connected to one end of the collision damper, and the collision block abuts against the outer wall of the column.

[0015] As a further improvement of the present invention, the inner wall of the sealing groove is slidingly connected with a first sealing block and a second sealing block, the inner wall of the sealing groove is fixedly connected with a support block, one end of the support block is fixedly connected with a second spring, and one end of the second spring is fixedly connected to the first sealing block.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] This solution incorporates a damper, extrusion spring, and rolling ball at the base of the column. Combined with the arc-shaped buffer structure of the rolling groove, this allows the rolling ball to slide within the rolling groove to disperse the impact force when the column deflects due to eccentric loads. Simultaneously, the damper and extrusion spring absorb most of the lateral force, preventing the column from transmitting excessive impact directly to the guide sleeve. This structural design effectively protects the column and guide sleeve, reducing wear and fatigue.

[0021] This solution utilizes an arc-shaped design at the bottom of the rolling groove, which cooperates with the rolling ball at the bottom of the column. When the column deflects, the rolling ball slides along the arc groove and returns to its lowest point under the elastic force of the extrusion spring, completing the automatic reset. This design ensures that the column always remains vertical, preventing deviation from affecting the motion trajectory of the movable crossbeam. At the same time, the electric push rod drives the friction arc block to lock the column. When machining small castings with high precision requirements, the automatic reset function ensures the precise alignment of the upper and lower forging heads, avoiding machining errors caused by column deviation, thereby improving the machining accuracy and quality of small workpieces.

[0022] This solution uses a feedback rod to record the amount of column deflection and impact force. The rod is engraved with a scale, allowing workers to intuitively understand the machine's operating status during processing. This data indicates potential equipment problems, allowing workers to quickly implement maintenance measures and avoid equipment damage or reduced processing accuracy caused by long-term deflection.

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] Example:

[0036] See also Figure 1-9A 10,000-ton winding free forging hydraulic press includes: an upper crossbeam 1, a guide rod assembly 2, a limit assembly 3 and a feedback assembly 4. A hydraulic pump 11 is installed on the top of the upper crossbeam 1, a guide tube 12 is installed at one end of the hydraulic pump 11, and a connecting pipe 13 is installed at the bottom end of the hydraulic pump 11. A hydraulic cylinder 14 is embedded in the upper crossbeam 1, and one end of the connecting pipe 13 is connected to the hydraulic cylinder 14. The output end of the hydraulic cylinder 14 is fixedly connected to a movable crossbeam 15, and an upper forging head 19 is installed at the bottom end of the movable crossbeam 15; the guide rod assembly 2 is provided with a plurality of columns 21, and the outer end of the movable crossbeam 15 is connected to the universal joint. A plurality of evenly distributed compression damping rods 16 are installed, and a guide sleeve 17 is slidably connected to the outer periphery of the column 21, and one end of the compression damping rod 16 is connected to the guide sleeve 17 through a universal joint; a plurality of limit assemblies 3 are provided, and the limit assemblies 3 include a limit cylinder 31, which is fixedly connected to the upper beam 1, and the inner wall of the limit cylinder 31 is connected to the column 21 through a universal joint; the feedback assembly 4 includes a workbench 41, which is arranged on the lower side of the upper beam 1, and a buffer platform is installed at the bottom end of the workbench 41, and a lower forging head 18 matching the upper forging head 19 is installed at the top of the workbench 41.

[0037] Among them, the 10,000-ton winding free forging hydraulic press achieves power output through the high degree of coordination between the hydraulic pump 11 and the hydraulic cylinder 14. The hydraulic pump 11 serves as the power source of the system and transports the hydraulic oil to the hydraulic cylinder 14 through the connecting pipe 13. After the hydraulic oil enters the hydraulic cylinder, it pushes the piston to produce linear motion, driving the movable crossbeam 15 and the upper forging head 19 to move downward, thereby applying forging pressure to the workpiece. The pressure and flow of the hydraulic pump are adjusted by the control valve to ensure that the hydraulic cylinder outputs stable forging force and realizes precise control of loading and unloading.

[0038] The equipment utilizes a single-cylinder design, simplifying the complexity of the hydraulic system and avoiding the crossbeam tilt problem caused by asynchrony in multi-cylinder structures. This single-cylinder structure ensures more uniform force distribution on the movable crossbeam 15, resulting in higher forging precision and reduced manufacturing and maintenance costs. Furthermore, the hydraulic system utilizes an ultra-high-pressure boosting mechanism. A booster device further increases the hydraulic pump's output pressure, significantly improving the equipment's pressure output capability and enabling it to meet the ultra-high pressure requirements of 10,000-ton forging operations. Furthermore, the booster device dynamically adjusts pressure, reducing inefficient power consumption and enhancing the equipment's operational efficiency.

[0039] Hydraulic cylinder 14 utilizes a wire-wound barrel structure. By prestressing the barrel with high-strength steel wire wrapped around its outer wall, the cylinder's pressure-bearing capacity is enhanced, allowing it to withstand ultra-high-pressure hydraulic oil without deformation or damage due to excessive internal pressure. Compared to traditional thick-walled barrels, this design not only reduces equipment weight and material costs, but also extends the cylinder's service life.

[0040] The use of boost loading and wire-wound cylinder structure significantly improves the pressure output efficiency and operating stability of the equipment. Through the single-cylinder structure and flexible pressure control, the equipment is suitable for forging complex and large workpieces, and can also meet the processing needs of high-precision and small workpieces.

[0041] By designing a damper, extrusion spring and rolling ball at the bottom of the column, combined with the arc-shaped buffer structure of the rolling groove, the column can be prevented from transmitting excessive impact force directly to the guide sleeve when the eccentric load causes the column to deviate, thereby improving the impact resistance and operating stability of the equipment when processing large castings. In addition, the rolling groove adopts an arc-shaped design, which cooperates with the rolling ball at the bottom of the column. When the column deviates, the rolling ball returns to the lowest point of the arc groove under the action of the extrusion spring, ensuring that the column always remains vertical. The friction arc block is driven by the electric push rod to lock the column. When processing small castings with high precision requirements, the precise alignment of the upper and lower forging heads is guaranteed, and the processing accuracy of small workpieces is improved. At the same time, the feedback rod records the offset and impact force, which makes it easier for workers to quickly identify problems and perform maintenance in time, avoiding equipment damage or reduced processing accuracy.

[0042] The bottom end of the column 21 is fixedly connected to a damper 22, an extrusion spring 23 is provided around the damper 22, and the bottom end of the damper 22 is fixedly connected to a moving block 24. The two ends of the extrusion spring 23 are respectively fixedly connected to the damper 22 and the moving block 24, and a rolling ball 25 is rotatably connected inside the moving block 24.

[0043] The inner wall of the limit assembly 3 is inlaid with multiple evenly distributed limit dampers 32, one end of the limit damper 32 is fixedly connected to the limit block 33, and the multiple limit blocks 33 are arranged outside the column 21, and the multiple limit blocks 33 are in contact with the outer wall of the column 21.

[0044] Among them, the column 21 is connected through the universal joint on the inner wall of the limit cylinder 31, so that the column 21 has a certain ability to rotate and can adapt to lateral forces and tilting moments in different directions during the forging process. When the hydraulic cylinder 14 drives the movable beam 15 to move downward, the upper forging head 19 at the bottom end of the movable beam 15 hits the casting. Due to the irregular shape or center offset of the casting, the guide sleeve 17 may be eccentric and tilted, and then force is applied to the column 21, causing the column 21 to deviate and rotate to a certain extent.

[0045] The damper 22 and the extrusion spring 23 designed at the bottom end of the column 21 work together. At this time, the moving block 24 fixed at the bottom end of the column 21 moves under the action of the lateral force, and drives the rolling ball 25 set inside it to roll in the rolling groove 42 opened in the workbench 41. The existence of the rolling ball 25 effectively reduces the friction between the column 21 and the workbench 41, making it more stable during the offset process. At the same time, when the column 21 deviates, the rolling ball 25 will hit the multiple collision dampers 43 and collision blocks 44 set in the rolling groove 42. Most of the lateral impact force is absorbed by the collision damper 43, protecting the column 21 and related structures from overload damage.

[0046] During the entire forging process, when the upper forging head 19 contacts the casting and causes the column 21 to deflect, the collision damper 43 and the collision block 44 in the rolling groove 42 effectively absorb the impact force generated by the deflection of the column 21, thereby reducing direct damage to the guide sleeve 17 and the column 21, and improving the equipment's ability to resist lateral forces and overall stability.

[0047] This design, through the synergistic effect of the damper 22, the extrusion spring 23, the moving block 24 and the rolling ball 25, combined with the buffering capacity of the collision damper 43 and the collision block 44, can effectively absorb the lateral force caused by the irregular shape or center offset of the workpiece, protect the guide structure and the column 21, and at the same time ensure the movement accuracy and forging effect of the movable beam 15, significantly improving the reliability and service life of the hydraulic press during high-frequency forging.

[0048] The inner wall of the limit assembly 3 is evenly inlaid with multiple limit dampers 32, one end of the limit damper 32 is fixedly connected to the limit block 33, and multiple limit blocks 33 are arranged around the outer periphery of the column 21 and directly abut against the outer wall of the column 21. The main purpose of this design is to effectively limit and buffer the deviation of the column 21 through the cooperation of the limit damper 32 and the limit block 33 when the column 21 is subjected to lateral force or tilting moment, so as to avoid excessive displacement of the column 21 or deviation from its normal working position, thereby protecting the overall stability and operation accuracy of the equipment, and also helping to reset the column 21.

[0049] A plurality of evenly distributed rolling grooves 42 are formed on the workbench 41 , and the corresponding shape of the bottom ends of the rolling grooves 42 is set to be arc-shaped.

[0050] An electric push rod is embedded in the inner wall of the rolling groove 42 , and a friction arc block 45 is fixedly connected to the output end of the electric push rod. A friction pad is installed on the inner wall of the friction arc block 45 .

[0051] The shape of the bottom end of the rolling groove 42 is designed to be an arc structure, the main purpose of which is to provide a self-resetting function during the displacement of the column 21. When the column 21 is subjected to lateral force or tilting torque, the rolling ball 25 at the bottom end of the column will slide in the rolling groove 42 and move along the curved surface of the arc structure. Due to the geometric characteristics of the arc structure, when the lateral force disappears, the rolling ball 25 can return to the lowest point of the arc structure under the joint action of the limit component 3 and the feedback component 4, thereby realizing automatic reset of the column 21.

[0052] The bottom end of the arc structure is designed as a stable balance point for the rolling ball 25, ensuring that when the external force disappears, the rolling ball can quickly return to its position, allowing the column 21 to return to a vertical state, thereby ensuring that the movable crossbeam 15 always maintains an accurate vertical motion trajectory when moving downward. Through this design, the problem of reduced forging accuracy caused by the offset or tilt of the column 21 can be effectively avoided, ensuring that the upper forging head 19 and the lower forging head 18 maintain precise alignment during the forging process, thereby improving the processing quality of the casting.

[0053] Furthermore, the curved structure disperses the pressure exerted by the rolling ball 25 on the inner wall of the rolling groove 42, reducing friction and wear during the sliding process, thereby extending the service life of the equipment. The overall design, through the implementation of a reset function, not only improves the forging accuracy of the equipment but also enhances its reliability and stability.

[0054] When the column 21 does not need to be movable, for example, when casting some small workpieces, it is only necessary to start the electric push rod, which drives the friction arc block 45 to move upward, so that the friction arc block 45 abuts against the rolling ball 25, and the column 21 is fixed by the high friction force between the friction arc block 45 and the rolling ball 25.

[0055] When the column 21 needs to slide in the rolling groove 42 to adapt to the deviation caused by external force during the casting process, the electric push rod is in a retracted state, the friction arc block 45 disengages from the rolling ball 25, and the rolling ball 25 at the bottom end of the column 21 can slide freely in the rolling groove 42, ensuring the normal operation of the equipment's buffering and reset functions.

[0056] When processing small workpieces or requiring higher stability, the electric push rod is started to drive the friction arc block 45 upward, contacting the rolling ball 25 and locking the column 21, thereby ensuring the stability of the column 21 and avoiding affecting the casting accuracy due to unnecessary movement.

[0057] The inner wall of the rolling groove 42 is provided with a plurality of evenly distributed sealing grooves 46 , in which a collision damper 43 is slidably connected. One end of the collision damper 43 is fixedly connected to a collision block 44 , which abuts against the outer wall of the column 21 .

[0058] The inner wall of the sealing groove 46 is slidably connected to a first sealing block 48 and a second sealing block 49 . The inner wall of the sealing groove 46 is fixedly connected to a support block 52 . One end of the support block 52 is fixedly connected to a second spring 50 . One end of the second spring 50 is fixedly connected to the first sealing block 48 .

[0059] The bottom end of the second sealing block 49 is fixedly connected to the first spring 51, and the bottom end of the first spring 51 is fixedly connected to the inner wall of the sealing groove 46. A feedback rod 47 is slidably connected in the sealing groove 46. The outer periphery of the feedback rod 47 is engraved with friction grooves, and the outer surface of the feedback rod 47 is engraved with scales.

[0060] Among them, a plurality of evenly distributed sealing grooves 46 are opened on the inner wall of the rolling groove 42, and a collision damper 43 is slidably connected in the sealing groove 46. One end of the collision damper 43 is fixedly connected to a collision block 44, and the collision block 44 abuts against the outer wall of the column 21. When the column 21 is offset due to the irregular shape of the workpiece or the eccentric load during the forging process, the rolling ball 25 at the bottom end of the column 21 will slide in the rolling groove 42 and collide with the collision damper 43 arranged in the sealing groove 46. The collision damper 43 absorbs the lateral force applied by the offset of the column 21 through the internal damping structure, thereby effectively alleviating the direct impact of external force on the rolling groove 42 and the column 21, reducing the wear or damage of key components of the equipment, and the cooperation of the collision damper 43 and the collision block 44 can achieve buffering and protection of the offset behavior of the column 21, ensuring that the equipment maintains stable operation during high-frequency forging.

[0061] The sealing groove 46 is designed not only to accommodate the collision damper 43, but also includes a set of dynamic sealing and feedback devices to realize the monitoring of the offset force and the automatic resetting of the equipment. The inner wall of the sealing groove 46 is slidingly connected with a first sealing block 48 and a second sealing block 49, which respectively play the role of sealing, buffering and force transmission in the structure. The inner wall of the sealing groove 46 is fixedly connected with a support block 52, one end of the support block 52 is fixedly connected with a second spring 50, and the other end of the second spring 50 is fixedly connected to the first sealing block 48. The second spring 50 provides support and elastic return ability for the first sealing block 48, so that it can maintain the sealing of the sealing groove 46 when subjected to collision force, and at the same time use the deformation of the spring to absorb part of the impact energy, thereby further buffering the impact force from the column 21.

[0062] A first spring 51 is fixedly connected to the bottom end of the second sealing block 49, and the other end of the first spring 51 is fixedly connected to the inner wall of the sealing groove 46. This design allows the second sealing block 49 to move upward when subjected to a force. At the same time, the first spring 51 provides a rebound force after the force is removed, quickly returning the second sealing block 49 to its original position. This dual-seal block design, through the synergistic action of the first and second sealing blocks 48, 49, and the springs, not only ensures the sealing and structural stability of the sealing groove 46 but also provides reliable protection for the normal operation of the feedback system.

[0063] A feedback rod 47 is slidably connected in the sealing groove 46, and the outer surface of the feedback rod 47 is engraved with friction grooves for increasing the friction between the feedback rod 47 and the inner wall of the sealing groove 46, thereby ensuring that the feedback rod can move stably when subjected to impact force, while avoiding loss of accuracy due to excessive sliding. The outer surface of the feedback rod 47 is also engraved with a scale for recording the maximum impact force or offset when the column 21 is offset during the forging process. When the collision damper 43 is subjected to a large impact force, the force will be transmitted to the sealing block and feedback rod 47 in the sealing groove 46 through the collision block 44, and the sealing block will be driven to move by air pressure, thereby pushing the feedback rod 47 upward, and the scale displays the corresponding impact amount or offset. Workers can observe the scale on the outside of the feedback rod 47 to know the maximum offset or impact force of the equipment when it is working, so as to determine whether the equipment needs maintenance or adjustment.

[0064] Through the buffering effect of the collision damper 43 and the collision block 44, the lateral impact force generated by the offset of the column 21 is effectively absorbed, and the structural stability of the rolling groove 42 and the column 21 is protected; through the dynamic sealing design of the first sealing block 48, the second sealing block 49 and the spring assembly, it is ensured that the sealing groove 46 maintains sealing under the action of impact force, and the reset function of the equipment is realized; through the friction pattern and scale design of the feedback rod 47, the movement state of the column 21 during the forging process is monitored in real time, providing accurate feedback data for equipment operation, facilitating workers to carry out maintenance and adjustments in a timely manner, which not only improves the reliability and durability of the equipment, but also significantly improves the forging accuracy and service life of the equipment.

[0065] Working principle:

[0066] Power output is achieved through the cooperation of the hydraulic pump 11 and the hydraulic cylinder 14. The hydraulic pump 11 transports hydraulic oil to the hydraulic cylinder 14 through the conduit 12 and the connecting pipe 13. The hydraulic oil pushes the hydraulic cylinder piston to produce linear motion, driving the movable crossbeam 15 and the upper forging head 19 to move downward, applying forging pressure to the workpiece. The movable crossbeam 15 is supported and guided by the column 21 and the guide sleeve 17 to ensure the stability and accuracy of its movement. During the processing, large castings may cause uneven distribution of forging loads due to irregular shapes or offset center of gravity, generating lateral force or tilting moment, causing the column 21 to deviate. In order to alleviate the impact of the deviation on the guide system, a damper 22, an extrusion spring 23 and a rolling ball 25 are designed at the bottom end of the column 21. The rolling ball 25 can slide in the rolling groove 42 on the workbench 41 to disperse the impact force and reduce friction. At the same time, the collision damper 43 and the collision block 44 absorb the lateral impact force. , protecting the guide sleeve 17 and the column 21 from damage. When the external force disappears, the arc design of the rolling groove 42 combined with the elastic action of the extrusion spring 23 causes the rolling ball 25 to quickly return to the lowest point of the arc groove, completing the automatic reset of the column 21 and ensuring that the movable crossbeam 15 maintains a vertical motion trajectory. In addition, the rolling groove 42 has an embedded feedback rod 47, the surface of which is engraved with friction grooves and scales, which can record the offset and impact force of the column 21. Workers can monitor the equipment status in real time through feedback data, which is convenient for timely maintenance or adjustment, thereby ensuring the stability and reliability of the equipment operation. The hydraulic cylinder 14 adopts a wire-wound cylinder structure to enhance the pressure-bearing capacity. Combined with the hydraulic pump pressure output capacity improved by the booster device, the equipment can meet the high-pressure requirements of 10,000-ton forging and realize stable processing of large and complex workpieces. At the same time, through the synergistic effect of the limit component 3 and the feedback component 4, the high-precision processing requirements of small workpieces are taken into account.
