Description

Technical Field

[0001] This invention relates to the field of metal material forging technology, specifically to a forging apparatus for mining card forgings. Background Technology

[0002] As the core load-bearing component of mining transportation equipment, mining truck forgings are characterized by large loads, harsh working conditions, and high forming precision requirements. Their forging quality directly determines the reliability and service life of the entire mining truck. Currently, mining truck forgings are mostly formed using multi-directional hydraulic forging devices. These devices typically consist of a main hydraulic cylinder, side hydraulic cylinders, an operating platform, and a frame. The forgings are formed by three-dimensional extrusion through the coordinated pressure of multiple cylinders.

[0003] In the prior art, the lateral hydraulic cylinder is easily affected by factors such as the reaction force of the forging, equipment vibration and assembly gap during the telescopic operation, resulting in horizontal and vertical deviations. This causes the cylinder output direction to deviate from the preset trajectory, leading to problems such as forging size deviation, local insufficient filling, and stress concentration, which seriously reduces the forming accuracy and mechanical properties of the forging.

[0004] Existing devices mostly use simple guiding structures or passive limiting methods, which make it difficult to monitor and dynamically correct cylinder deviation in real time. The correction response is lagging and the effect is limited. At the same time, there is a lack of synchronous lubrication and protection for the cylinder and the surface of the forging during the forging process. The contact between the high-temperature billet and the cylinder can easily aggravate component wear. Lubricants such as graphite emulsion are difficult to spray evenly, which further affects the forging stability and product surface quality.

[0005] Furthermore, the existing equipment does not integrate vibration detection and active correction functions, making it difficult to accurately adjust the correction amplitude based on the cylinder vibration signal. This makes it difficult to meet the high-efficiency and high-precision continuous forging requirements of large mining truck forgings, thus restricting the improvement of mining truck forging production efficiency and product qualification rate. Summary of the Invention

[0006] This invention addresses the problems existing in the prior art by proposing a forging device for mining truck forgings. It solves the problems that make it impossible to achieve high-precision continuous forging of large mining truck forgings due to the difficulty in real-time monitoring and dynamic correction of cylinder offset, lack of synchronous lubrication protection during forging, and uneven lubricant spraying.

[0007] This invention is achieved through the following technical solution: A forging apparatus for mining card forgings includes an outer frame, a first hydraulic cylinder mounted on the top of the outer frame, an operating platform mounted on the bottom of the outer frame, and second hydraulic cylinders symmetrically mounted on the left and right sides of the outer frame. Conducting components are symmetrically arranged on the upper and lower sides of each of the second hydraulic cylinders, and a vibration component is connected to the end of each conducting component away from the second hydraulic cylinder. A spraying component is positioned above the second hydraulic cylinders. The conducting components include a conducting box, a second spring installed between the top and bottom inner walls of the conducting box, a connecting block on one outer surface of the second spring, a vibrating rod mounted on one side of the connecting block, and a base mounted on the bottom outer wall of the conducting box, the base being tightly fitted against the outer surface of the second hydraulic cylinder. The spraying component includes a liquid storage tank, and the vibrating rod extends into the liquid storage tank through a hole in one outer wall of the conducting box.

[0008] Furthermore, two vertical partitions are provided inside the frame, dividing the interior of the outer frame into three cavities. A first hydraulic cylinder and a limit cylinder are installed at the top of the middle cavity inside the outer frame. The output end of the limit cylinder is located above the output end of the first hydraulic cylinder. The second hydraulic cylinders are installed on the inner walls of the left and right cavities of the outer frame, and the output ends of the second hydraulic cylinders extend through the corresponding partitions to the middle cavity.

[0009] Furthermore, support rods are installed on the top of both the left and right cavities of the outer frame; the upper vibration component is connected to the bottom of the corresponding support rod, and the lower vibration component is fixed to the bottom of the inner side of the outer frame.

[0010] Furthermore, a first vibration detector is installed on the top of each of the two cavities on the left and right sides of the outer frame, and the first vibration detector is located directly above the corresponding second hydraulic cylinder; a second vibration detector is installed on the inner wall of each of the two cavities on the left and right sides of the outer frame; the second vibration detector is located at a horizontal position on one side of the corresponding second hydraulic cylinder.

[0011] Furthermore, the vibration assembly includes a vibration box, with multiple partitions installed in the middle of the inner wall of the vibration box, and a vibration motor installed on one side of each partition.

[0012] Furthermore, a flywheel is installed at the output end of the vibration motor, and a sliding box is installed on the other side of the partition. Two vibrating plates are installed in the middle of the inner wall of each sliding box. A first spring connects the two vibrating plates to the inner wall of the corresponding sliding box, and the flywheel is tightly attached to one side of the two vibrating plates.

[0013] Furthermore, the conduction box is connected to the corresponding vibration box.

[0014] Furthermore, connecting rods are respectively mounted on the two opposite outer walls of the transmission box via bearings, and rollers are installed between the two sets of connecting rods, with the rollers tightly fitting against the outer surface of the second hydraulic cylinder.

[0015] Furthermore, an oil pump is installed on the inner wall of the bottom of the liquid storage tank, and a spray nozzle is installed on the outer wall of the bottom of the liquid storage tank. A nozzle is installed at the bottom of the spray nozzle and is located directly above the output end of the second hydraulic cylinder.

[0016] Furthermore, a sealing head is provided at the connection between the vibrator and the liquid storage tank, and the sealing head is fitted onto the outer surface of the vibrator.

[0017] The beneficial effects of this invention compared to the prior art are as follows: 1. This invention, by setting a first vibration detector and a second vibration detector at corresponding positions on the outer frame, can collect vibration signals of the second hydraulic cylinder in the vertical and horizontal directions in real time, accurately identifying the offset trend caused by equipment vibration and assembly gaps during the cylinder's extension and retraction, thus solving the deficiency of traditional devices that rely solely on passive guidance and limiting, which cannot monitor in real time. The system quickly drives the vibration component to start based on the vibration signal. The vibration motor drives the flywheel to rotate, periodically squeezing the vibration plate and cooperating with the first spring to drive the sliding box to generate stable vibration. The vibration is synchronously transmitted to the transmission box, the second spring, the base, and the connecting rod roller structure. The outer wall of the second hydraulic cylinder uses dynamic vibration compensation to correct cylinder offset in real time, ensuring that the cylinder output direction is always consistent with the preset trajectory. The roller rolls along the outer wall of the second hydraulic cylinder, which reduces frictional resistance and achieves multi-directional limiting constraints to prevent the offset from expanding. This design forms a closed-loop control from monitoring and driving to execution, which can effectively eliminate problems such as forging size deviation, local insufficient filling, and stress concentration, greatly improve the forming accuracy and mechanical property uniformity of mining truck forgings, ensure the dimensional stability of large mining truck forgings in the continuous forging process, reduce the defect rate, and meet the high-precision forming requirements of heavy-duty mining forgings.

[0018] 2. This invention integrates vibration correction and lubrication protection functions. The vibrating rod of the transmission component, driven by the second spring, extends synchronously into the liquid storage tank of the spraying component. The device's own vibration power continuously stirs the graphite emulsion, preventing lubricant sedimentation and stratification, ensuring uniform concentration and stable flow of the sprayed medium. No additional stirring motor is required, simplifying the structure and reducing energy consumption. The liquid storage tank is connected to the vibrating rod via a rubber sealing head, which can adapt to vibration action and effectively prevent graphite emulsion leakage, improving safety. The oil pump accurately delivers the uniformly stirred graphite emulsion through the spray nozzle and spray head to the output end of the second hydraulic cylinder and the surface of the forging, achieving simultaneous completion of correction and lubrication protection. This avoids wear, scratches, and thermal damage to components caused by direct contact between the high-temperature forging blank and the cylinder, significantly extending the service life of the hydraulic cylinder and forging die. The uniformly covered graphite emulsion reduces the friction coefficient during forging, improves metal flow, reduces surface scratches and wrinkles on the forging, improves the surface finish and appearance quality of the forging, and reduces equipment maintenance frequency and cost, while enhancing the continuous operation capability of the forging production line.

[0019] 3. This invention adopts a modular integrated layout of an outer frame, multiple hydraulic cylinders, vibration components, transmission components, and spraying components. The structure is compact and reasonable, easy to install and maintain, and adaptable to the processing space and load requirements of large forgings for mining trucks. The first hydraulic cylinder works in conjunction with the limit cylinder to achieve precise limiting and stable pressure application in the main forging direction, preventing cylinder overtravel and improving equipment operating safety. The support rod provides stable support for the vibration components, ensuring vibration transmission efficiency and reliable correction action. The entire device can achieve integrated monitoring, correction, and lubrication without a complex electrical control system, with fast response speed and high control precision. It can adapt to efficient continuous forging cycles, effectively solving the problems of lagging correction, single function, and poor adaptability of traditional devices.

[0023] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this invention clearer, the invention will be further described in detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The technical solutions of this invention are described in detail below with reference to the embodiments and accompanying drawings, but the scope of protection is not limited thereto.

[0024] Please see Figures 1 to 9 This embodiment proposes a forging device for mining card forgings, including an outer frame 10. The outer frame 10 has two vertical partitions inside, dividing the interior of the outer frame 10 into three cavities. A first hydraulic cylinder 11 and a limit cylinder 12 are installed on the top of the middle cavity inside the outer frame 10. Support rods 13 and first vibration detectors 14 are installed on the top of the left and right cavities inside the outer frame 10. A second hydraulic cylinder 15 is installed on the inner wall of the left and right cavities inside the outer frame 10. The output end of the second hydraulic cylinder 15 extends through the corresponding partition to the middle cavity.

[0025] An operating platform 16 is installed at the bottom of the middle cavity of the outer frame 10. An opening for inserting the forging blank of the mining card is provided above the operating platform 16 on the outer frame 10. The operating platform 16 is located directly below the first hydraulic cylinder 11. A second vibration detector 17 is installed on the inner wall of the left and right cavities inside the outer frame 10. The second vibration detector 17 is located at a horizontal position on one side of the corresponding second hydraulic cylinder 15. A transmission component 3 is symmetrically arranged on the upper and lower sides of the second hydraulic cylinder 15. A vibration component 2 is connected to the end of the transmission component 3 away from the second hydraulic cylinder 15. The upper vibration component 2 is connected to the bottom of the corresponding support rod 13, and the lower vibration component 2 is fixed to the bottom of the inner side of the outer frame 10.

[0026] Two partitions are each equipped with a spraying assembly 4; the output end of the limit cylinder 12 is located above the output end of the first hydraulic cylinder 11, and the first vibration detector 14 is located directly above the corresponding second hydraulic cylinder 15; the outer frame 10 adopts a rigid frame structure, with the support rod 13 serving as the support carrier for the upper vibration assembly 2, ensuring a stable vibration transmission path; the transmission assembly 3 is sequentially connected to the vibration assembly 2 to achieve directional transmission of vibration power; the spraying assembly 4 and the transmission assembly 3 work together to complete synchronous lubrication. The overall design adopts a modular layout, with clear positioning and tight fit of each component, which can adapt to the multi-directional forging requirements of mining truck forgings.

[0027] like Figures 5 to 7 As shown, the vibration assembly 2 includes a vibration box 20. Multiple partition plates 21 are installed in the middle of the inner wall of the vibration box 20. A vibration motor 22 is installed on one side of each partition plate 21, and a flywheel 23 is installed at the output end of the vibration motor 22. A sliding box 24 is installed on the other side of each partition plate 21. Two vibrating plates 25 are installed in the middle of the inner wall of each sliding box 24. A first spring 26 connects the two vibrating plates 25 to the corresponding inner wall of the sliding box 24. The flywheel 23 is tightly fitted to one side of the two vibrating plates 25. The vibration assembly 2 uses the vibration box 20 as the mounting base and achieves internal vibration through the partition plates 21. The structure is divided and the components are fixed; the vibration motor 22 provides rotational driving force, which drives the flywheel 23 to rotate continuously. The eccentric effect of the flywheel 23 forms a periodic squeezing force on the vibrating plate 25; under the combined action of the flywheel 23 and the first spring 26, the vibrating plate 25 drives the sliding box 24 to complete the composite vibration in the horizontal and vertical directions, so that the vibration energy is stably output to the transmission component 3; this structure can adjust the vibration frequency and direction according to the detection signal to form a compensating vibration opposite to the cylinder offset, providing a stable and controllable power source for offset correction, and ensuring that the correction action is accurate and reliable.

[0028] like Figures 5 to 9 As shown, the transmission assembly 3 includes a transmission box 30, which is connected to the vibration box 20. A second spring 31 is installed between the inner top wall and the inner bottom wall of the transmission box 30. A connecting block 32 is provided on one outer surface of the second spring 31, and a vibrating rod 33 is installed on one side of the connecting block 32. A base 34 is installed on the outer bottom wall of the transmission box 30, and the base 34 is tightly attached to the outer surface of the second hydraulic cylinder 15. The vibrating rod 33 passes through a hole opened in one outer wall of the transmission box 30. Two connecting rods 35 are respectively installed on the two opposite outer walls of the transmission box 30 through bearings. A roller 36 is installed between the two sets of connecting rods 35, and the roller 36 is tightly attached to the outer surface of the second hydraulic cylinder 15. The transmission assembly 3 receives vibration energy from the vibration assembly 2 through the transmission box 30. Under the action of vibration, the second spring 31 drives the connecting block 32 and the vibrating rod 33 to move synchronously, realizing the transmission and conversion of vibration. The base 34 at the bottom of the transmission box 30 is tightly attached to the outer wall of the second hydraulic cylinder 15 to ensure that the vibration acts stably on the outer wall of the second hydraulic cylinder 15.

[0029] like Figure 9 As shown, the spraying assembly 4 includes a liquid storage tank 40, with the end of a vibrating rod 33 extending into the liquid storage tank 40. A sealing head 44 is provided at the connection between the vibrating rod 33 and the liquid storage tank 40. The sealing head 44 is sleeved on the outer surface of the vibrating rod 33 and is made of rubber. An oil pump 41 is installed on the inner wall of the bottom of the liquid storage tank 40, and a spray nozzle 42 is installed on the outer wall of the bottom of the liquid storage tank 40. A nozzle 43 is installed at the bottom of the spray nozzle 42 and is located directly above the output end of the second hydraulic cylinder 15. The spraying assembly 4 uses the liquid storage tank 40 as a storage carrier and has an internal oil pump 41 to provide conveying power. The spray nozzle 42 and the nozzle 43 achieve directional and uniform spraying of graphite emulsion. The sealing head 44 is movably sleeved with the vibrating rod 33, which forms a sealing barrier while ensuring vibration transmission and preventing graphite emulsion leakage. The vibrating rod 33 vibrates synchronously with the transmission component 3, continuously agitating and stirring the graphite emulsion in the storage tank 40 to prevent the medium from settling and separating, and to ensure the stability of the lubricating medium concentration. This structure can immediately perform spraying operations after the correction is completed, so as to realize the simultaneous completion of cylinder protection and forging lubrication.

[0030] The working principle of the technical solution provided by this invention is as follows: First, the forging blank is placed on the operating table 16. The first hydraulic cylinder 11 and the limit cylinder 12 at the top of the outer frame 10 are activated, and the output end of the limit cylinder 12 extends. The output end of the limit cylinder 12 is located above the output end of the first hydraulic cylinder 11. At the same time, the limit cylinder extends. The support rod 13 is installed on the top of the outer frame 10. The support rod 13 provides support for the vibration component 2 above. At this time, the second hydraulic cylinder 15 is activated, and the output end extends. At the same time, the first vibration detector 14 and the second vibration detector 17 are activated. The first vibration detector 14 is located directly above the second hydraulic cylinder 15, and the second vibration detector 17 is located to one side of the second hydraulic cylinder 15. The first vibration detector 14 collects the vertical vibration signal of the second hydraulic cylinder 15, and the second vibration detector 17 collects the horizontal vibration signal of the second hydraulic cylinder 15. The first vibration detector 14 and the second vibration detector 17 output the detection signals and upload them to the system.

[0031] Then, upon system command to activate vibration assembly 2, two sets of vibration motors 22 located on one side of partition plate 21 control their rotation speed according to the same frequency and opposite direction detected by the first vibration detector 14 and the second vibration detector 17. The two sets of vibration motors 22 respectively drive flywheel 23 to rotate, thereby counteracting the lateral and vertical offset generated at the output end of the second hydraulic cylinder 15. The two sets of vibration motors 22 drive flywheel 23 to rotate, and flywheel 23 periodically compresses vibrating plate 25. Vibrating plate 25 drives the first spring 26 to extend and retract, and the first spring 26 drives sliding box 24 to move horizontally and vertically. The vertical movement is transmitted from the vibration box 20 to the transmission component 3. When the second hydraulic cylinder 15 extends and retracts, causing a deviation, the transmission box 30 receives the vibration transmitted by the vibration box 20. Under the action of vibration, the second spring 31 drives the transmission box 30 and the base 34 at the bottom of the transmission box 30 to move horizontally. At the same time, the connecting rod 35 moves with the transmission box 30, and the roller 36 rolls along the outer wall of the second hydraulic cylinder 15. The roller 36 restricts the deviation direction of the second hydraulic cylinder 15 and corrects the cylinder deviation in real time in a dynamic vibration compensation manner to ensure that the cylinder output direction is always consistent with the preset trajectory.

[0032] Finally, after the offset correction is completed, the spraying assembly 4 completes the subsequent work. The oil pump 41 located on the inner wall of the bottom of the storage tank 40 starts. At the same time, the connecting block 32 located on the outer surface of the second spring 31 vibrates with the vibration of the second spring 31, driving the vibrating rod 33 to vibrate inside the storage tank 40 to stir the graphite emulsion. The sealing head 44 is a movable rubber part that can prevent the graphite emulsion inside the storage tank 40 from overflowing. Then, the oil pump 41 delivers the graphite emulsion inside the storage tank 40 to the spray nozzle 42. The graphite emulsion is sprayed out by the nozzle 43 and sprayed onto the output end of the second hydraulic cylinder 15 and the surface of the mining forging. At this time, the process is complete. When the second hydraulic cylinder 15 extends and retracts, causing deviation, the correction and spraying operations are performed. The two sets of vibration motors 22 are de-energized, the flywheel 23 stops rotating, the vibrating plate 25 and the first spring 26 return to their initial state, and the second spring 31 resets. At this time, the output ends of the first hydraulic cylinder 11 and the second hydraulic cylinder 15 simultaneously compress the mining card forging, completing the forging of the mining card forging. The output ends of the first hydraulic cylinder 11 and the second hydraulic cylinder 15 retract, the output end of the limit cylinder 12 retracts, the first vibration detector 14 and the second vibration detector 17 stop working, and the operator removes the mining card forging from the operating table 16.
