Description

Technical Field

[0001] The present invention relates to the technical field of casting processing equipment, and particularly to a precision casting hydraulic processing and shaping equipment and a shaping method thereof. Background Technique

[0002] During the production process of castings, due to factors such as material inhomogeneity, cooling rate differences, and mold design, defects such as warping and deformation often occur. These defects may not have a great impact on the use of ordinary castings, but in the processing of precision castings, proper shaping treatment must be carried out to ensure the dimensional accuracy and surface quality of the castings. Therefore, a precision casting hydraulic processing and shaping equipment is required.

[0003] The precision casting hydraulic processing and shaping equipment is a special equipment for shaping precision castings. The traditional casting shaping method mainly relies on manual trimming. This method not only has low work efficiency, but also has a large labor intensity, and it is difficult to guarantee the shaping accuracy. At the same time, most traditional hydraulic shaping equipment does not have a special buffer mechanism and cannot effectively absorb and release energy during the extrusion process, resulting in the castings being easily affected by excessive impact force during the shaping process, which affects the shaping quality and surface quality. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a precision casting hydraulic processing and shaping equipment and a shaping method thereof, which solve the problem that the effect of absorbing and releasing energy during the extrusion process of the traditional hydraulic shaping equipment is not ideal enough, resulting in the castings being easily affected by excessive impact force during the shaping process, which affects the shaping quality and surface quality.

[0007] Preferably, the tooth end of the rack is meshed with a gear, a screw rod is fixedly connected to the inside of the gear, one end of the screw rod is rotatably connected to the inside of the support frame, and the other end of the screw rod is rotatably connected to a support frame.

[0008] Preferably, the outer wall of the support frame is fixedly connected to the outer wall of the support frame, the screw rod is threadedly connected with a connecting frame, the outer wall of the connecting frame is slidably connected to the inside of the support frame, and a brush roller is rotatably connected to the inside of the connecting frame.

[0009] Preferably, a fixing frame is fixedly connected to the outer wall of the support frame, and a U-shaped frame is fixedly connected to the lower surface of the fixing frame.

[0010] Preferably, a motor is fixedly connected to the inside of the U-shaped frame, an output end of the motor is fixedly connected to a connecting shaft, and the outer wall of the connecting shaft is rotatably connected to the inside of the fixing frame.

[0011] Preferably, a connecting frame is fixedly connected to the outer wall of the connecting shaft, a fixing shaft is fixedly connected to the inside of the connecting frame, and a connecting rod is rotatably connected to the outer wall of the fixing shaft.

[0012] Preferably, a clamping arm is rotatably connected to the outer wall of the connecting rod, and a placing plate is slidably connected to the outer wall of the connecting rod.

[0013] Preferably, the lower surface of the placing plate is fixedly connected to the outer wall of the fixing frame, a sliding groove is formed in the inside of the placing plate, and the outer wall of the clamping arm is slidably connected to the inner wall of the sliding groove.

[0014] Preferably, a shaping method for a precision casting hydraulic processing and shaping device is used for a precision casting hydraulic processing and shaping device according to any one of claims 1-9, and the method includes the following steps: S1. Place the casting to be shaped on the placing plate, and then start the motor to drive the clamping arm to clamp and limit the casting; S2. Then start the hydraulic cylinder to push the limiting plate to slide on the slide rail, and then drive the brush roller to clean the surface of the casting through the rack, gear and screw rod; S3. The limiting plate drives the pressing plate to perform extrusion and shaping treatment on the casting through the telescopic rod; S4. Take out the shaped casting and check the quality of the shaped casting.

[0015] Working principle: When the device needs to be used, first place the casting to be shaped on the placement plate, then start the motor. The motor drives the connecting shaft to rotate in the fixed frame, and the connecting shaft drives the connecting frame to rotate. The connecting frame drives the connecting rod to rotate through the fixed shaft, and the connecting rod drives the clamping arm to slide in the chute, thereby clamping and limiting the casting to be shaped, achieving the effect of clamping and limiting castings of different sizes, reducing manual operation errors, ensuring the accurate position of the casting during the shaping process, and improving the shaping accuracy.

[0016] Then start the hydraulic cylinder. The hydraulic cylinder pushes the limiting plate to slide on the slide rail. At this time, the limiting plate drives the rack to slide in the limiting frame, the rack drives the gear to rotate, the gear drives the screw rod to rotate between the support frame and the support frame, and then the screw rod drives the connecting frame to slide in the support frame. Driven by the connecting frame, the brush roller can clean the surface of the casting, achieving the effect of rotating and cleaning the surface of the casting, effectively removing dust, impurities, burrs, etc. on the surface of the casting, making the surface of the casting cleaner and smoother, and providing better conditions for subsequent processing or use.

[0017] At this time, with the continuous sliding of the limiting plate, the limiting plate drives the pressing plate to slide on the slide rail through the telescopic rod. When the pressing plate contacts the casting, the connecting frame has driven the brush roller to slide away from the surface of the casting. At this time, under the blocking of the casting and the continuous sliding of the limiting plate, the telescopic rod will be squeezed and the first spring will be compressed. At the same time, the limiting column will slide in the limiting plate, and the second spring will be squeezed under the blocking of the limiting plate. After the limiting plate rises, the connecting frame will drive the brush roller to clean the shaped casting again, achieving the effect of buffer extrusion shaping of the casting, avoiding excessive impact force on the casting, reducing damage such as scratches and indentations on the surface of the casting, and improving the surface quality of the casting.

[0018] The present invention provides a hydraulic processing and shaping device for precision castings and its shaping method. It has the following beneficial effects: 1. In the present invention, the hydraulic cylinder is used to push the limiting plate to slide on the slide rail, and then the telescopic rod drives the pressing plate to slide on the slide rail. When the pressing plate contacts the casting, under the blocking of the casting and the continuous sliding of the limiting plate, the telescopic rod will be squeezed and the first spring will be compressed. At the same time, the limiting column will slide in the limiting plate, and then the second spring will be squeezed under the blocking of the limiting plate, achieving the effect of buffer extrusion shaping of the casting and improving the surface quality of the casting.

[0019] 2. In the present invention, the hydraulic cylinder is used to push the limiting plate to slide on the sliding rail. Then, the limiting plate will drive the rack to slide in the limiting frame and drive the gear to rotate at the same time. Then, the gear drives the screw rod to rotate, and further drives the connecting frame to slide in the supporting frame. Driven by the connecting frame, the brush roller can clean the surface of the casting, achieving the effect of rotating and cleaning the surface of the casting, making the surface of the casting cleaner and smoother, and providing better conditions for subsequent processing or use.

[0020] 3. In the present invention, the motor drives the connecting frame to rotate through the connecting shaft. Then, the connecting frame drives the connecting rod to rotate through the fixed shaft. Further, the connecting rod drives the clamping arm to slide in the chute, so as to clamp and limit the casting to be shaped, achieving the effect of clamping and limiting castings of different sizes and ensuring the accurate position of the casting during the shaping process.

[0023] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the specification. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to the attached Figure 1 - Attachment Figure 4 , an embodiment of the present invention provides a precision casting hydraulic processing and shaping device, including a support frame 1. A connecting block 2 is fixedly connected to the outer wall of the support frame 1. A hydraulic cylinder 3 is fixedly connected to the inside of the connecting block 2. The output end of the hydraulic cylinder 3 is fixedly connected to a limiting plate 4. A telescopic rod 5 is fixedly connected to the lower surface of the limiting plate 4. A first spring 6 is fixedly connected to the outer wall of the telescopic rod 5. The bottom end of the telescopic rod 5 is fixedly connected to a pressing plate 7. A rack 11 is fixedly connected to the outer wall of the limiting plate 4. A limiting frame 12 is slidably connected to the outer wall of the rack 11. The outer wall of the limiting frame 12 is fixedly connected to the outer wall of the pressing plate 7. The upper surface of the pressing plate 7 is fixedly connected to the outer wall of the first spring 6. Slide rails 8 are slidably connected to the inside of both the limiting plate 4 and the pressing plate 7. The outer wall of the slide rails 8 is fixedly connected to the outer wall of the support frame 1. A limiting component is arranged on the upper surface of the pressing plate 7.

[0025] Specifically, the connecting block 2 plays a role in supporting and fixing the hydraulic cylinder 3. The hydraulic cylinder 3 is used to push the limiting plate 4 to slide on the slide rail 8. At this time, the limiting plate 4 drives the rack 11 to slide in the limiting frame 12. The limiting plate 4 drives the pressing plate 7 to slide on the slide rail 8 through the telescopic rod 5. The slide rail 8 plays a role in supporting the limiting plate 4 and the pressing plate 7, thereby providing a stable movement track for the limiting plate 4 and the pressing plate 7, and further increasing the stability of the limiting plate 4 and the pressing plate 7 during the sliding process. When the pressing plate 7 contacts the casting, under the blocking action of the casting and the continuous sliding of the limiting plate 4, the telescopic rod 5 is squeezed and the first spring 6 is compressed. The main function of the first spring 6 is buffering and energy storage. When the telescopic rod 5 is compressed, the first spring 6 absorbs part of the energy and stores it, thereby reducing the impact force received by the casting. The telescopic action of the telescopic rod 5 can also absorb part of the pressure, playing an auxiliary buffering role to prevent the casting from being subjected to excessive impact force. At this time, the limiting column 9 will slide in the limiting plate 4. Under the blocking action of the limiting plate 4, the second spring 10 is squeezed at the same time, thereby achieving the effect of buffering and squeezing the shaping of the casting, so as to avoid the casting from being subjected to excessive impact force, thereby reducing damage such as scratches and indentations on the surface of the casting and improving the surface quality of the casting.

[0026] Please refer to the attached Figure 3 and attachment Figure 4 , the limiting component includes a limiting column 9. The bottom end of the limiting column 9 is fixedly connected to the upper surface of the pressing plate 7.

The outer wall of the second spring 10 is fixedly connected to the lower surface of the limiting plate 4.

[0027] Specifically, the limiting plate 4 supports and limits the limiting column 9, and the limiting column 9 supports and limits the pressing plate 7, thereby ensuring the stability of the movement trajectory of the pressing plate 7. At the same time, when the second spring 10 is compressed, it also plays a certain buffering role on the casting.

[0028] Please refer to the appendix Figure 5 and the appendix Figure 6 , the tooth end of the rack 11 is meshed and connected with the gear 13, the inside of the gear 13 is fixedly connected with a screw rod 14, one end of the screw rod 14 is rotatably connected inside the support frame 1, and the other end of the screw rod 14 is rotatably connected with a support frame 15.

[0029] Specifically, the rack 11 drives the gear 13 to rotate, and the gear 13 drives the screw rod 14 to rotate between the support frame 1 and the support frame 15. The support frame 1 and the support frame 15 together support and limit the screw rod 14, thereby increasing the stability of the rotation of the screw rod 14.

[0030] Please refer to the appendix Figure 6 , the outer wall of the support frame 15 is fixedly connected to the outer wall of the support frame 1.

[0031] Specifically, the support frame 1 supports and fixes the support frame 15. The screw rod 14 drives the connecting frame 16 to slide in the support frame 15. The support frame 15 supports and limits the connecting frame 16 and provides a trajectory for the movement of the connecting frame 16, increasing the stability of the movement of the connecting frame 16. Driven by the connecting frame 16, the brush roller 17 thus plays a role in cleaning the surface of the casting.

[0032] Please refer to the appendix Figure 1 and the appendix Figure 7 , the outer wall of the support frame 1 is fixedly connected with a fixed frame 18, and the lower surface of the fixed frame 18 is fixedly connected with a U-shaped frame 19.

[0033] Specifically, the support frame 1 supports the fixed frame 18, and the fixed frame 18 supports and fixes the U-shaped frame 19.

[0034] Please refer to the appendix Figure 7 , the inside of the U-shaped frame 19 is fixedly connected with a motor 20, the output end of the motor 20 is fixedly connected with a connecting shaft 21, and the outer wall of the connecting shaft 21 is rotatably connected inside the fixed frame 18.

[0035] Specifically, the U-shaped frame 19 serves to support and fix the motor 20. The motor 20 drives the connecting shaft 21 to rotate in the fixed frame 18, and the fixed frame 18 also plays a certain role in limiting the connecting shaft 21.
