Description

Technical Field

[0001] This invention relates to the field of mold manufacturing technology, specifically to a rotary forging mold processing device and processing method. Background Art

[0002] Rotary forging is a machining method that uses a die to rotate and forge metal workpieces. It combines the advantages of rotation and plastic deformation, effectively improving the mechanical properties of metals. Rotary forging dies are commonly used to process high-strength, complex-shaped metal parts, such as critical components in the aerospace, automotive, and energy industries. The design of rotary forging dies typically requires precise consideration of the characteristics of the metal being processed, process requirements, and the die's lifespan. The die material needs to possess sufficient wear resistance, thermal stability, and deformation resistance to withstand high-temperature and high-pressure working environments.

[0003] The existing rotary forging die processing equipment and processing method include the following process: manufacturing a rotary forging die blank, and then using a diamond grinding wheel to finish the rotary forging die blank; during the finish machining of the rotary forging die blank, the diamond grinding wheel is mounted on a CNC milling machine, and then a CNC program is set on the CNC milling machine. The CNC milling machine controls the running trajectory of the diamond grinding wheel to process the rotary forging die blank according to the set data program.

[0004] The aforementioned application document describes the use of a rapidly rotating grinding wheel to polish the forging die. However, during the polishing process, the debris generated during polishing is rapidly ejected from the device, which may affect the operator's use of the device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a rotary forging die processing device and method, solving the problems mentioned in the background section. To achieve the above objectives, this invention is implemented through the following technical solution: a rotary forging die processing device, comprising: The base has a top plate connected to its top via an electric telescopic rod, and the top plate is fitted with a movable seat. An electric grinding wheel is mounted at the bottom of the movable base, a movable clamp is mounted on the top of the base, and a grinding fluid delivery hose is mounted on the top of the base. The bottom of the movable base is equipped with a partition plate, and the top of the electric grinding wheel is driven by a rotating rod. A protective plate is rotatably connected to the side of the partition plate. A transmission component for transmission is installed between the rotating rod and the protective plate. The side of the clamping seat is equipped with an auxiliary clamping assembly for clamping the mold, and the side of the partition plate is equipped with an auxiliary assembly for injecting grinding fluid. This design reduces the possibility of debris rapidly splashing out of the device during polishing with the electric grinding wheel rotating rapidly, making the device easier to use.

[0006] Preferably, the transmission component includes a hydraulic chamber one mounted on the outside of the rotating rod. The inner wall of the hydraulic chamber one is connected to a sliding block by a spring one. The side of the hydraulic chamber one is slidably connected to an arc-shaped plate by a piston. The top of the partition is equipped with a hydraulic chamber two. One end of the hydraulic chamber two is slidably connected to a force-bearing rod one by a piston. The other end of the hydraulic chamber two is slidably connected to an arc-shaped rod one by a piston. The side of the force-bearing rod one is equipped with a spring two.

[0007] Preferably, the force-bearing rod is located on the side of the arc-shaped plate and is in contact with the arc-shaped plate.

[0008] Preferably, the arc-shaped rod is located on the side of the protective plate and is fixed to the protective plate.

[0009] Preferably, the auxiliary clamping assembly includes a hydraulic chamber three mounted on the side of the partition plate, a force-bearing rod two slidably connected to the side of the hydraulic chamber three via a piston, a spring three mounted on the side of the force-bearing rod two, a hydraulic hose mounted on the side of the hydraulic chamber three, a hydraulic chamber four mounted on the side of the clamping seat, an arc-shaped rod two slidably connected to the side of the hydraulic chamber four via a piston, and a clamping plate rotatably connected to the side of the clamping seat. By setting up the auxiliary clamping assembly, the rotary forging die can be auxiliaryly clamped, improving the stability of the device during use.

[0010] Preferably, the second force-bearing rod is located on the side of the arc-shaped plate and is in contact with the arc-shaped plate.

[0011] Preferably, the clamp is located on the side of the second arc-shaped rod and is fixed to the second arc-shaped rod.

[0012] Preferably, the auxiliary component includes a rigid tube mounted on the side of the partition and penetrating the partition. A sprocket is mounted on the outer side of the rotating rod, and a chain is mounted on the outer side of the sprocket. A through-drive rod is rotatably connected inside the rigid tube. A second sprocket is fixedly connected to the top of the drive rod, and a block is fixedly connected to the bottom of the drive rod. By setting up the auxiliary component, grinding fluid can be intermittently injected into the electric grinding wheel through the rigid tube, improving the processing effect of the device while reducing grinding fluid waste and making the device easier to use.

[0013] Preferably, the end of the chain furthest from the first sprocket is fitted to the outer side of the second sprocket.

[0014] A processing method for a rotary forging die processing device includes the following steps: Step 1: Place the rotary forging die on the base, between the two clamps, and activate the clamps driven by the servo motor to perform the initial clamping operation on the rotary forging die. Step 2: Activate the top plate and movable seat equipped with the electric telescopic rod, and move the electric grinding wheel to the desired position; Step 3: Use the electric grinding wheel driven by the servo motor to process the rotary forging die.

[0015] This invention provides a rotary forging die processing device and method. It has the following beneficial effects: (1) The rotary forging die processing device and processing method, when processing the rotary forging die, the electric grinding wheel rotates rapidly, driving the rotating rod to rotate rapidly. With the help of the partition plate, hydraulic chamber one, spring one, sliding block, arc plate, hydraulic chamber two, force rod one, arc rod one, spring two and protective plate, the gap between the electric grinding wheel and the rotary forging die can be sealed. This reduces the possibility of debris flying out of the device rapidly during the polishing process when the electric grinding wheel rotates rapidly, making the device easier to use.

[0016] (2) The rotary forging die processing device and processing method, when the arc plate extends synchronously during rotation, it can squeeze the second force rod, so that the second force rod moves to the side. In conjunction with the third hydraulic chamber, the third spring, the hydraulic hose, the fourth hydraulic chamber and the second arc rod, the clamping plate rotates at a certain angle, which can assist in clamping the rotary forging die and improve the stability of the device during use.

[0017] (3) When the rotary forging die processing device and processing method are being processed, grinding fluid is injected through the grinding fluid delivery hose. When the rotating rod is in the rotating state, it drives the first sprocket to rotate. In conjunction with the chain, the second sprocket rotates. The second sprocket drives the transmission rod to rotate, which in turn drives the block to rotate. In this way, the grinding fluid can be intermittently injected into the electric grinding wheel through the hard pipe, which improves the processing effect of the device and reduces the waste of grinding fluid, making the device easier to use.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Example 1, please refer to Figures 1-4 A rotary forging die processing device and processing method, comprising: The base 100 has a top plate 200 connected to its top via an electric telescopic rod, and the top plate 200 is fitted with a movable seat 300. An electric grinding wheel 400 is mounted at the bottom of a movable base 300. A movable clamping seat 500 is mounted on the top of a base 100, and a grinding fluid delivery hose 900 is mounted on the top of the base 100. The rotary forging die is placed on the base 100 and positioned between the two clamping seats 500. The clamping seats 500, driven by a servo motor, are activated, and the two clamping seats 500 move towards each other to perform an initial clamping operation on the rotary forging die. The top plate 200, equipped with an electric telescopic rod, and the movable base 300 are activated to move the electric grinding wheel 400 to the desired position. The electric grinding wheel 400, driven by a servo motor, is then activated to process the rotary forging die. A partition 601 is mounted on the bottom of the movable base 300. A rotating rod 602 is driven to the top of the electric grinding wheel 400. A protective plate 611 is rotatably connected to the side of the partition 601. A transmission component for transmission is mounted between the rotating rod 602 and the protective plate 611. The transmission component includes a hydraulic chamber 603 mounted on the outside of the rotating rod 602. During machining, the electric grinding wheel 400 rotates rapidly, driving the rotating rod 602 mounted on the electric grinding wheel 400 to rotate rapidly, which in turn drives the hydraulic chamber 603 mounted on its outside to rotate rapidly.

[0022] The inner wall of the hydraulic chamber 603 is connected to a sliding block 605 via a spring 604, and the side of the hydraulic chamber 603 is slidably connected to an arc-shaped plate 606 via a piston. When the hydraulic chamber 603 rotates rapidly, the sliding block 605 inside the hydraulic chamber 603 stretches the spring 604 under the action of centrifugal force, moving along the inner wall of the hydraulic chamber 603, thereby squeezing the oil originally stored in the hydraulic chamber 603, and the oil then flows to the side of the arc-shaped plate 606.

[0023] The top of the partition 601 is equipped with a hydraulic chamber 2 607. One end of the hydraulic chamber 2 607 is slidably connected to a force-bearing rod 1 608 via a piston. The force-bearing rod 1 608 is located on the side of the arc-shaped plate 606 and is in contact with the arc-shaped plate 606. The other end of the hydraulic chamber 2 607 is slidably connected to an arc-shaped rod 1 609 via a piston. The arc-shaped rod 1 609 is located on the side of the protective plate 611 and is fixed to the protective plate 611. A spring 2 610 is installed on the side of the force-bearing rod 1 608. When oil flows towards the side of the arc-shaped plate 606, the arc-shaped plate 606 extends synchronously during rotation, thereby squeezing the force-bearing rod 608. This causes the force-bearing rod 608 to move into the hydraulic chamber 607, squeezing the oil originally stored in the hydraulic chamber 607. The oil, squeezed by the force-bearing rod 608, flows towards the end near the arc-shaped rod 609, causing the arc-shaped rod 609 to extend out of the hydraulic chamber 607. This causes the arc-shaped rod 609 to rotate the protective plate 611 fixedly connected to it. The protective plate 611 rotates to the side position of the partition 601, which, together with the partition 601, seals the gap between the electric grinding wheel 400 and the rotary forging die. This reduces the possibility of debris flying out of the device rapidly during the polishing process when the electric grinding wheel 400 rotates quickly, making the device easier to use.

[0024] After processing is completed, the electric grinding wheel 400 stops rotating, which means the hydraulic chamber 603 stops rotating. The sliding block 605 loses its centrifugal force and can then reset under the action of spring 604. Similarly, the arc plate 606 resets. At this point, the force rod 608 loses the constraint of the arc plate 606 and resets under the action of spring 610, thus causing the arc rod 609 to drive the protective plate 611 to reset. This facilitates the next use of the device.

[0025] In use, the rotary forging die is placed on the base 100, positioned between two clamps 500. The clamps 500, driven by a servo motor, are activated, and the two clamps 500 move towards each other to initially clamp the rotary forging die. The top plate 200 and the movable seat 300, equipped with an electric telescopic rod, are then activated to move the electric grinding wheel 400 to the desired position. The electric grinding wheel 400, driven by a servo motor, then processes the rotary forging die. At this time, the electric grinding wheel 400 rotates rapidly, causing the rotating rod 602 mounted on it to rotate rapidly. This causes the rotating rod 602 to drive the hydraulic chamber 603 mounted on its outer side to rotate rapidly. The sliding block 605 inside the hydraulic chamber 603, under centrifugal force, stretches the spring 604 and moves along the inner wall of the hydraulic chamber 603, thereby squeezing the oil originally stored in the hydraulic chamber 603. The oil then flows towards the arc plate 606, causing the arc plate 606 to extend synchronously during rotation, thus squeezing the oil. The force rod 608 moves into the hydraulic chamber 607, compressing the oil stored there. The oil, compressed by the force rod 608, flows towards the end near the arc-shaped rod 609, causing it to extend out of the hydraulic chamber 607. This causes the arc-shaped rod 609 to rotate the fixedly connected protective plate 611, moving it to the side of the partition 601. The partition 601 then engages with the electric sander... The gap between wheel 400 and the rotary forging die is sealed; after processing is completed, the electric grinding wheel 400 stops rotating, that is, the hydraulic chamber 603 stops rotating, the sliding block 605 loses the centrifugal force, and can be reset under the action of spring 604. Similarly, the arc plate 606 is reset. At this time, the force rod 608 can be freed from the restriction of the arc plate 606 and reset under the action of spring 610, so that the arc rod 609 drives the protective plate 611 to complete the reset.

[0026] Example 2, please refer to Figures 1-6 Based on Embodiment 1, the side of the clamping seat 500 is equipped with an auxiliary clamping assembly 700 for clamping the mold. The auxiliary clamping assembly 700 includes a hydraulic chamber 3 701 mounted on the side of the partition 601. A force-bearing rod 2 702 is slidably connected to the side of the hydraulic chamber 3 701 via a piston. The force-bearing rod 2 702 is located on the side of the arc plate 606 and is in contact with the arc plate 606. A spring 3 703 is mounted on the side of the force-bearing rod 2 702, and a hydraulic hose 704 is mounted on the side of the hydraulic chamber 3 701. When the arc plate 606 rotates, it extends synchronously, which can squeeze the force-bearing rod 2 702, causing the force-bearing rod 2 702 to move to the side. At this time, the force-bearing rod 2 702 slides into the hydraulic chamber 3 701, which is slidably connected to it via a piston, squeezing the oil originally stored in the hydraulic chamber 3 701, so that some of the oil flows into the hydraulic hose 704 connected to the hydraulic chamber 3 701.

[0027] The side of the clamp 500 is equipped with a hydraulic chamber 4 705. The side of the hydraulic chamber 4 705 is slidably connected to an arc rod 2 706 via a piston. The side of the clamp 500 is rotatably connected to a clamping plate 707. The clamping plate 707 is located on the side of the arc rod 2 706 and is fixed to the arc rod 2 706. When oil flows into the hydraulic hose 704, some of the oil inside the hydraulic hose 704 is squeezed and flows into the hydraulic chamber 705, which is connected to the hydraulic hose 704. This causes the oil originally stored in the hydraulic chamber 705 to be squeezed and flow. The oil then flows towards the end near the arc-shaped rod 706, which moves the arc-shaped rod 706, which is slidably connected to the hydraulic chamber 705 via a piston. The arc-shaped rod 706 extends out of the hydraulic chamber 705, thereby causing the clamping plate 707, which is fixedly connected to the arc-shaped rod 706, to rotate. The clamping plate 707 rotates at a certain angle, which can assist in clamping the rotary forging die and improve the stability of the device during use.

[0028] After processing is completed, the electric grinding wheel 400 stops rotating, which means the hydraulic chamber 603 stops rotating. The sliding block 605 loses its centrifugal force and can then reset under the action of spring 604. Similarly, the arc-shaped plate 606 resets. At this point, the force-bearing rod 702 loses the force of the arc-shaped plate 606 and can reset under the action of spring 703. Likewise, the arc-shaped rod 706 drives the clamping plate 707 to reset, facilitating the next use of the assembly.

[0029] In use, based on Embodiment 1, when the arc-shaped plate 606 extends synchronously during rotation, it can squeeze the second force-bearing rod 702, causing the second force-bearing rod 702 to move laterally. At this time, the second force-bearing rod 702 slides into the third hydraulic chamber 701, which is slidably connected to it via a piston, squeezing the oil originally stored in the third hydraulic chamber 701. This causes some of the oil to flow into the hydraulic hose 704, which is connected to the third hydraulic chamber 701. The oil in the hydraulic hose 704 is then squeezed and flows into the fourth hydraulic chamber 705, which is connected to the hydraulic hose 704. This causes the oil originally stored in the fourth hydraulic chamber 705 to be squeezed and flow, and the oil then flows towards the end closer to the second arc-shaped rod 706, driving the oil in the fourth hydraulic chamber 705 to move towards the end connected to the second hydraulic rod 706. The arc-shaped rod 706, which is connected to the piston by sliding, moves between the two parts. The arc-shaped rod 706 extends out from the hydraulic chamber 705, thereby driving the clamping plate 707, which is fixedly connected to the arc-shaped rod 706, to rotate. The clamping plate 707 rotates at a certain angle, which can assist in clamping the rotary forging die. After the processing is completed, the electric grinding wheel 400 stops rotating, that is, the hydraulic chamber 603 stops rotating. The sliding block 605 loses the centrifugal force and can be reset under the action of the spring 604. Similarly, the arc-shaped plate 606 is reset. At this time, the force rod 702 loses the action of the arc-shaped plate 606 and can be reset under the action of the spring 703. Similarly, the arc-shaped rod 706 drives the clamping plate 707 to complete the reset.

[0030] Example 3, please refer to Figures 1-8 Based on Embodiments 1 and 2, an auxiliary component 800 for injecting grinding fluid is mounted on the side of the partition 601. The auxiliary component 800 includes a rigid pipe 801 mounted on the side of the partition 601 and penetrating the partition 601, and a sprocket 802 mounted on the outer side of the rotating rod 602. During processing, grinding fluid is injected through the grinding fluid delivery hose 900, and when the rotating rod 602 is in a rotating state, it drives the sprocket 802 mounted on the outer side of the rotating rod 602 to rotate.

[0031] A chain 803 is mounted on the outside of sprocket 1 802. A through transmission rod 804 is rotatably connected inside the rigid tube 801. A sprocket 2 805 is fixedly connected to the top of the transmission rod 804. The end of the chain 803 away from sprocket 1 802 is mounted on the outside of sprocket 2 805. A block 806 is fixedly connected to the bottom of the transmission rod 804. When sprocket 1 802 rotates, it engages with chain 803 mounted on the outside of sprocket 1 802, causing sprocket 2 805, which is connected to sprocket 1 802 via chain 803, to rotate. Sprocket 2 805 drives transmission rod 804, which is fixedly connected to it, to rotate. Transmission rod 804 then drives block 806, which is fixedly connected to it, to rotate. Block 806 is located inside rigid pipe 801, and rigid pipe 801 is connected to grinding fluid delivery hose 900. In this way, grinding fluid can be intermittently injected into electric grinding wheel 400 through rigid pipe 801, improving the processing effect of the device, reducing grinding fluid waste, and making the device easier to use.

[0032] In use, based on Embodiment 1 and Embodiment 2, during processing, grinding fluid is injected through the grinding fluid delivery hose 900. When the rotating rod 602 is rotating, it drives the sprocket 802 mounted on the outside of the rotating rod 602 to rotate. In conjunction with the chain 803 mounted on the outside of the sprocket 802, the sprocket 805, which is connected to the sprocket 802 via the chain 803, rotates. The sprocket 805 drives the transmission rod 804, which is fixedly connected to it, to rotate. The transmission rod 804 drives the block 806, which is fixedly connected to it, to rotate. The block 806 is located inside the rigid pipe 801, and the rigid pipe 801 is connected to the grinding fluid delivery hose 900. In this way, the grinding fluid can be intermittently injected into the electric grinding wheel 400 through the rigid pipe 801.
