Description

Technical Field

[0001] This utility model mainly relates to the technical field of metal processing and manufacturing, specifically a rapid rough grinding device for processing the outer wall of metal bars. Background Technology

[0002] In the field of metal processing and manufacturing, grinding the outer wall of metal bars is a common processing step. Traditional methods of grinding the outer wall of metal bars mainly rely on manual hand-held grinding tools or semi-automatic grinding using simple mechanical devices. Manual grinding has many drawbacks. On the one hand, manual grinding is inefficient, requiring operators to repeat the same actions for extended periods, resulting in high labor intensity. Furthermore, the grinding quality is greatly affected by the operator's skill level and fatigue level, making it difficult to guarantee the stability and consistency of grinding quality. On the other hand, manual grinding generates a large amount of metal dust and noise, posing a serious threat to the operator's health. While existing simple mechanical devices improve grinding efficiency to some extent, they still have some problems. For example, these devices usually require manual placement of the metal bar into the grinding position, which is cumbersome and prone to positional deviations, leading to uneven grinding. In addition, some devices have a simple grinding structure that cannot be flexibly adjusted according to the diameter of the metal bar. Different specifications of metal bars require different grinding tools or adjustments to complex mechanical structures, increasing processing costs and time. Meanwhile, these devices lack an effective feeding and unloading mechanism during the grinding process, making it impossible to achieve continuous automatic grinding of metal bars and limiting further improvement in production efficiency.

[0003] According to application number CN201922000325.0, a semi-automatic metal bar grinding device is provided, belonging to the field of machining technology. It includes a base plate, with lifting cylinders mounted on both sides of the upper part of the base plate. A lifting frame is mounted on the upper part of the lifting cylinders, and a top plate is mounted on the upper part of the lifting frame. A motor mounting plate is mounted on the right side of the top plate. A first motor is mounted on the upper part of the motor mounting plate. A first bevel gear is mounted on the left side of the first motor. A second bevel gear meshes with the lower part of the first bevel gear. A bevel gear shaft is mounted on the lower part of the second bevel gear. A grinding disc is mounted on the lower part of the bevel gear shaft. A second motor is mounted in the middle of the upper part of the base plate. A driving gear is mounted on the right side of the second motor. A driven gear meshes with the upper part of the driving gear. A gear shaft is mounted on the right side of the driven gear. A three-jaw chuck is mounted on the right side of the gear shaft. An adapter plate is mounted on the left side of the three-jaw chuck. A mounting seat is mounted in the middle of the gear shaft.

[0004] In summary, a rapid rough grinding device capable of automatic feeding, efficient grinding, and adaptability to metal bars of different specifications is a technical problem that urgently needs to be solved by those in this field. Utility Model Content

[0022] Example

[0023] like Figures 1 to 4 As shown, a rapid rough grinding device for processing the outer wall of metal bars includes a component placement box 10. Grinding rollers 11 are symmetrically arranged on the inner wall of the component placement box 10. A placement side plate 12 is provided at the bottom of one end of the component placement box 10. A drive motor 13 is symmetrically arranged on the top of the placement side plate 12. A lifting cylinder 19 is provided on the top of the placement side plate 12 and on one side of the drive motor 13. Connecting support rods 14 are provided at both ends of the top of the component placement box 10. A feeding box 15 is provided on one side of the connecting support rod 14 and on the top of the component placement box 10. A push block 16 is provided at the actuating end of the lifting cylinder 19. A connecting rod 17 is provided on the side wall of one end of the push block 16. A top block 18 is provided at the other end of the connecting rod 17 and inside the feeding box 15.

[0024] The component placement box 10 has a V-shaped feed port 101 at the top and at the bottom of the feeding box 15.

[0025] One end of the grinding roller shaft 11 is connected to the actuator of the drive motor 13 via a belt 111.

[0026] The bottom inner wall of the feeding box 15 is provided with an arc-shaped bottom plate 151, and the side wall of the feeding box 15 and the two sides of the arc-shaped bottom plate 151 are provided with limiting elongated holes 152. One end of the feeding box 15 is provided with a feeding side box 153.

[0027] The side box 153 near the end of the feeding box 15 has a through hole 154, and the bottom of the side box 153 has a feeding port 155.

[0028] The inner wall of the limiting elongated hole 152 is slidably connected to the outer wall of one end of the connecting rod 17.

[0029] The material feeding box 15 has a material storage cavity 156 located inside and on top of the arc-shaped bottom plate 151.

[0030] It should be noted that, in this embodiment, the device as a whole includes a component placement box 10, and a placement side plate 12 is provided at the bottom of one end of the component placement box 10. The component placement box 10 and the placement side plate 12 are the main load-bearing structures of the entire device. Grinding roller shafts 11 are symmetrically installed on the inner wall of the component placement box 10. The grinding roller shafts 11 are used to grind the outer wall of the metal bar.

[0031] A drive motor 13 is symmetrically mounted on the top of the mounting side plate 12. The drive motor 13 provides power for the rotation of the grinding roller shaft 11. In addition, a lifting cylinder 14 is provided on the top of the mounting side plate 12 and on the side of the drive motor 13. The lifting cylinder 14 is used to provide thrust to push the metal bar in the feeding box 15 and to push the material located on the top of the grinding roller shaft 11.

[0032] The top two ends of the component placement box 10 are provided with connecting support rods 14, which serve to support and connect. A feeding box 15 is provided on one side of the connecting support rod 14 and located on the top of the component placement box 10. The feeding box 15 is used to store metal rods to be polished.

[0033] The lifting cylinder 14 is equipped with a push block 16 at its actuating end. One side wall of the push block 16 is equipped with a connecting rod 17, and the other end of the connecting rod 17, located in the inner cavity of the feeding box 15, is equipped with a top block 18. Through the extension and retraction movement of the lifting cylinder 14, the push block 16, the connecting rod 17 and the top block 18 are driven to move. On the one hand, the top block 18 pushes the metal bar to be ground from the storage cavity 156 in the feeding box 15 to the feeding side box 153; on the other hand, the push block 16 pushes the metal bar located at the top of the grinding roller shaft 11 to the other end.

[0034] A V-shaped feed inlet 101 is provided at the top of the component placement box 10 and at the bottom of the unloading box 15. The design of the V-shaped feed inlet 101 allows the metal bar falling from the unloading box 15 to accurately enter the component placement box 10 and be located between the two grinding roller shafts 11, preparing for subsequent grinding operations.

[0035] One end of the grinding roller shaft 11 is connected to the actuator of the drive motor 13 via a belt 111. When the drive motor 13 starts, the grinding roller shaft 11 is driven to rotate through the belt 111; the two symmetrically arranged grinding roller shafts 11 rotate in opposite directions to quickly rough grind the outer wall of the metal bar material that enters between them.

[0036] The bottom inner wall of the feeding box 15 is provided with an arc-shaped bottom plate 151. The design of the arc-shaped bottom plate 151 allows the metal bar to slide smoothly downward. The side wall of the feeding box 15 and the two sides of the arc-shaped bottom plate 151 are provided with limiting elongated holes 152. The inner wall of the limiting elongated holes 152 is slidably connected to the outer wall of one end of the connecting rod 17. The limiting elongated holes 152 play a limiting and guiding role in the movement of the connecting rod 17, ensuring that the connecting rod 17 can accurately drive the top block 18 to move.

[0037] The feeding box 15 has a feeding side box 153 at one end. The feeding side box 153 has a through hole 154 at the end near the feeding box 15. The through hole 154 facilitates the metal bar to enter the feeding side box 153 from the feeding box 15. The bottom of the feeding side box 153 has a feeding port 155. When the top block 18 pushes the metal bar into the feeding side box 153, the metal bar falls from the feeding port 155 and enters the V-shaped feed port 101.

[0038] The working principle of this utility model is as follows:

[0039] In actual operation, the metal bar to be ground is placed into the storage cavity 156 of the feeding box 15. The feeding box 15 continuously receives the metal bar to be ground through the conveying component. The drive motor 13 is started, and the drive motor 13 drives the grinding roller shaft 11 to rotate through the belt 111. At the same time, the lifting cylinder 14 is started. The actuator of the lifting cylinder 14 pushes the push block 16 to move. The push block 16 drives the connecting rod 17 to slide in the limiting elongated hole 152. The connecting rod 17 then drives the top block 18 to move. The top block 18 pushes the metal bar in the storage cavity 156 to the feeding side box 153. The metal bar falls from the feeding port 155 and enters the component placement box 10 through the V-shaped feeding port 101, located between the two rotating grinding roller shafts 11, to achieve rapid rough grinding of the outer wall of the metal bar. Once a metal bar has been ground, the lifting cylinder 14 resets, and the next metal bar automatically slides down to the front of the top block 18 under gravity, waiting for the next push and grinding. At the same time, the push block 16 pushes the metal bar located at the top of the grinding roller shaft 11 to the other end. This cycle is repeated to achieve continuous and rapid rough grinding of the metal bar.

[0040] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
