Description

Technical Field

[0001] This utility model relates to the field of metal forging technology, and in particular to a hammering processing device for metal forging. Background Technology

[0002] Metal forging is a processing method that uses forging machinery to apply pressure or impact to metal billets, causing them to undergo plastic deformation in a solid state, thereby obtaining metal parts with specific shapes, sizes, and mechanical properties.

[0003] In metal forging, the forging device is a key piece of equipment for achieving the plastic deformation of metal billets. Existing forging devices suffer from inadequate protective structures, leading to the easy splashing of metal chips and high-temperature sparks during forging, posing safety hazards. Furthermore, replacing the forging head is inconvenient; traditional devices often use bolts for fixing, requiring the disassembly of multiple fasteners during replacement, impacting processing efficiency and rendering them impractical. Therefore, a new forging device for metal forging needs to be designed to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a hammering processing device for metal forging.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A forging and hammering processing device for metal forging includes a base. A bearing plate is fixedly installed on the upper surface of the base via a support column. A hydraulic cylinder is fixedly installed on the upper surface of the base via a support frame. An installation plate is fixedly installed on the telescopic end of the hydraulic cylinder. A connecting block is slidably installed on the bottom wall of the installation plate via a connecting sleeve. A hammering head is fixedly installed on the bottom wall of the connecting block. Fixing frames are fixedly installed on both outer walls of the connecting block. Movable openings that cooperate with the fixing frames are opened on both outer walls of the connecting sleeve. Two prismatic rods are slidably installed through the bottom wall of the installation plate via a support plate. A lever is fixedly installed at one end of each of the two prismatic rods. The inner walls of the two levers are connected to the outer wall of the support plate on the same side via a fixing mechanism. A wedge block that cooperates with the fixing frame is fixedly installed at the other end of each of the two prismatic rods. Two connecting frames are fixedly installed on the upper surface of the base. Protective covers are fixedly installed inside each of the two connecting frames via multiple bolts. Electric actuators are fixedly installed on the outer walls of each of the two protective covers via connecting plates. Extension covers are fixedly connected to the telescopic ends of the two electric actuators via a moving mechanism.

[0006] Preferably, the fixing mechanism includes a fixing spring fixedly installed on the outer wall of the prism rod, and the two ends of the fixing spring are elastically connected to the outer wall of the connecting sleeve and the inner wall of the lever, respectively.

[0007] Preferably, the moving mechanism includes a moving block fixedly installed at the telescopic end of the electric actuator, and the end of the moving block is fixedly connected to the outer wall of the extension cover.

[0008] Preferably, guide rods are fixedly installed on the inner walls of both sides of the support frame via guide frames, and guide plates are slidably installed on the outer walls of the two guide rods, with the ends of the two guide plates being fixedly connected to the outer wall of the mounting plate.

[0009] Preferably, a hydraulic station is fixedly installed on the upper surface of the base, and the hydraulic station is connected to the hydraulic cylinder through an oil pipe.

[0010] Preferably, a controller is fixedly installed on the upper surface of the base via a connecting plate, and the controller is electrically connected to two electric actuators and a hydraulic station.

[0011] The beneficial effects of this utility model are: 1. By setting up components such as protective covers, electric actuators, and extension covers, the protection range can be flexibly adjusted according to the different sizes of workpieces to be forged. The electric actuator can drive the extension cover to extend or retract, so that the protective cover and the extension cover form a closed protective space, effectively blocking metal chips and high-temperature sparks generated during the forging process, and greatly improving operational safety.

[0012] 2. By incorporating components such as a fixed frame, a prismatic rod, a fixing spring, and a wedge block, a quick-change function for the hammer head is achieved. During replacement, simply pull the lever to disengage the wedge block from the fixed frame, allowing the connecting block and hammer head to be removed. After installing the new hammer head, release the lever; the fixing spring returns to its original position, causing the wedge block to snap into the fixed frame for secure installation. No bolts or other fasteners need to be removed, making the operation simple and quick, significantly reducing replacement time and improving processing efficiency.

[0013] 3. By setting up components such as guide frames, guide rods, and guide plates, the movement of the mounting plate can be stably guided, ensuring that the mounting plate drives the hammer head to always move in the vertical direction, avoiding lateral deviation, ensuring the accuracy of the forging position, and improving forging precision and product quality.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-5 A forging and hammering processing device for metal forging includes a base 1. A bearing plate 3 is fixedly installed on the upper end face of the base 1 via a support column 2. A hydraulic cylinder 5 is fixedly installed on the upper end face of the base 1 via a support frame 4. An installation plate 6 is fixedly installed on the telescopic end of the hydraulic cylinder 5. A connecting block 8 is slidably installed on the bottom wall of the installation plate 6 via a connecting sleeve 7. A hammering head 9 is fixedly installed on the bottom wall of the connecting block 8. Fixing frames 10 are fixedly installed on both outer walls of the connecting block 8. Movable openings that cooperate with the fixing frames 10 are opened on both outer walls of the connecting sleeve 7. Two rods are slidably installed through the bottom wall of the installation plate 6 via a support plate 11. Two prismatic rods 12 are provided, with a lever 13 fixedly installed at one end of each rod. The inner walls of the two levers 13 are connected to the outer wall of the support plate 11 on the same side via a fixing mechanism. The other ends of the two prismatic rods 12 are fixedly installed with wedge blocks 15 that cooperate with the fixing frame 10. Two connecting frames 19 are fixedly installed on the upper surface of the base 1. Protective covers 20 are fixedly installed inside the two connecting frames 19 via multiple bolts. Electric push rods 22 are fixedly installed on the outer walls of the two protective covers 20 via connecting plates 21. Extension covers 24 are fixedly connected to the telescopic ends of the two electric push rods 22 via a moving mechanism.

[0018] The fixing mechanism includes a fixing spring 14 fixedly installed on the outer wall of the prism rod 12. The two ends of the fixing spring 14 are elastically connected to the outer wall of the connecting sleeve 7 and the inner wall of the lever block 13, respectively.

[0019] Furthermore, the fixed spring 14 is made of stainless steel and has good elastic restoring performance. Its initial state is a compressed state, which can always apply a pulling force towards the connecting sleeve 7 to the dial 13, thereby driving the wedge block 15 on the prism rod 12 to tightly abut against the fixed frame 10, ensuring that the connecting block 8 will not loosen during the hammering process.

[0020] The moving mechanism includes a moving block 23 fixedly installed at the telescopic end of the electric actuator 22, and the end of the moving block 23 is fixedly connected to the outer wall of the extension cover 24.

[0021] Furthermore, the movable block 23 is made of high-strength aluminum alloy, which not only has the advantage of being lightweight, reducing the load on the electric actuator 22 during extension and retraction, but also has good structural strength, capable of withstanding the lateral force generated during the movement of the extension cover 24.

[0022] Guide rods 17 are fixedly installed on both inner walls of the support frame 4 via guide frames 16. Guide plates 18 are slidably installed on the outer walls of the two guide rods 17. The ends of the two guide plates 18 are fixedly connected to the outer wall of the mounting plate 6.

[0023] Furthermore, when the hydraulic cylinder 5 drives the mounting plate 6 to rise and fall, the guide plate 18 will slide synchronously along the guide rod 17, which will guide the rising and falling direction of the mounting plate 6, prevent the mounting plate 6 from tilting due to uneven force, and ensure that the hammer head 9 can act accurately on the workpiece.

[0024] A hydraulic station 25 is fixedly installed on the upper surface of the base 1. The hydraulic station 25 is connected to the hydraulic cylinder 5 through an oil pipe.

[0025] Furthermore, the hydraulic station 25 is equipped with components such as a hydraulic pump, oil tank, relief valve, and directional valve. The hydraulic pump is driven by a motor to pressurize the hydraulic oil in the oil tank and then deliver it to the hydraulic cylinder 5 through the oil pipe, thereby realizing the extension and retraction of the hydraulic cylinder 5. The oil pipe is made of high-pressure rubber hose with a steel wire braided layer on the outside, which can withstand the pressure of high-pressure hydraulic oil and prevent the oil pipe from bursting. Sealing joints are installed at the connection between the oil pipe and the hydraulic cylinder 5 and the hydraulic station 25 to ensure that the hydraulic oil does not leak.

[0026] A controller 27 is fixedly installed on the upper surface of the base 1 via a connecting plate 26. The controller 27 is electrically connected to two electric actuators 22 and a hydraulic station 25.

[0027] Furthermore, the controller 27 adopts a PLC control system, and its surface is equipped with a touch screen and operation buttons. The touch screen can display parameters such as the working pressure of the hydraulic cylinder 5, the extension speed, and the extension length of the electric push rod 22 in real time. The operator can adjust various parameters through the operation buttons to realize the automated control of the device. The controller 27 is connected to the electric push rod 22 and the hydraulic station 25 by a shielded cable to reduce the impact of external electromagnetic interference on signal transmission and ensure that control commands can be accurately transmitted. At the same time, the controller 27 is also equipped with an overload protection module. When the device experiences overload, overvoltage or other abnormal conditions, it can automatically cut off the power supply to protect the safety of the device and the operator.

[0028] When using this utility model, the metal workpiece to be forged is placed on the support plate 3. According to the size of the workpiece, the electric push rod 22 is started by the controller 27. The electric push rod 22 drives the extension cover 24 to extend through the moving block 23 and is adjusted to a suitable protection range. When the metal workpiece is being hammered, the hydraulic station 25 is started by the controller 27. The hydraulic station 25 drives the hydraulic cylinder 5 to extend and retract. The hydraulic cylinder 5 drives the mounting plate 6 to move up and down. The mounting plate 6 drives the hammering head 9 to forge the workpiece on the support plate 3 through the connecting sleeve 7 and the connecting block 8. During the forging process, the guide plate 18 slides along the guide rod 17 to ensure the vertical movement trajectory of the hammering head 9. When it is necessary to replace the hammer head 9 with a different specification, pull the lever 13 to both sides. The lever 13 drives the prism rod 12 to stretch the fixing spring 14, so that the wedge block 15 is disengaged from the fixing frame 10. At this time, the connecting block 8 can be removed from the connecting sleeve 7. After replacing the new hammer head 9, release the lever 13. The fixing spring 14 resets and drives the wedge block 15 to re-enter the fixing frame 10. After the replacement of the hammer head 9 is completed and the forging is finished, close the hydraulic station 25 and the electric push rod 22 through the controller 27. The electric push rod 22 drives the extension cover 24 to reset. The finished workpiece can then be removed.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
