Description

Technical Field

[0001] This invention relates to the field of casting production equipment technology, specifically to a surface grinding device for steel production. Background Technology

[0002] Traditionally, castings are polished manually to remove burrs and particles from the surface. However, this method is not only labor-intensive, but also cannot polish the casting surface evenly. Improper operation can even damage the casting. A casting surface polishing device with application number 2016112122460 includes a frame with a polishing box installed on the frame. Compared with existing technologies, this device polishes the casting surface more evenly.

[0003] Although this device has the advantages mentioned above, it still has the following drawbacks in practical use:

[0004] 1) The device polishes the surface of the casting with abrasive sand and agitates the abrasive sand by rotating the rod. However, the movement of the abrasive sand is uneven, resulting in uneven polishing effect.

[0005] 2) This device uses abrasive to polish castings, but after polishing, no separation measures are set for the abrasive chips, which makes it difficult to separate the abrasive chips and easily affects the polishing effect. At the same time, the movement of the abrasive is driven by magnetism, which makes the abrasive easily magnetized, thus affecting the polishing effect.

[0006] Therefore, it is necessary to address the aforementioned problems. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a surface grinding device for steel production. It solves the problems of existing grinding devices that grind castings with abrasive sand. On the one hand, the abrasive sand is prone to magnetization, which leads to uneven movement of the abrasive sand by the rotating rod, thus reducing the grinding effect. On the other hand, the lack of a grinding chip separation measure makes the separation of grinding chips difficult and easily affects the grinding work.

[0016] Beneficial effects

[0017] This invention provides a surface grinding device for steel production. Compared with the prior art, it has the following advantages:

[0018] (1) By setting up a grinding mechanism, the surface of the casting can be ground around the ring by rotating in a ring. At the same time, the grinding block is driven to move by an electric push rod. On the one hand, it can grind castings of different shapes and improve grinding efficiency and uniformity. On the other hand, the grinding block can still grind the casting as it wears down.

[0019] (2) By setting up a shielding component, the distance between the arc plates can be adjusted by using the push-pull rod and the rotating frame to shield the outside of the grinding area, thereby avoiding the splashing of grinding chips and allowing the grinding chips to be uniformly recycled.

[0020] (3) By setting up a filter unit, the grinding chips can be continuously filtered using filter plates, filter cylinders and blowers, which facilitates continuous grinding of castings. At the same time, the filter cylinder is rotated by adjusting the motor, which causes the filter plates to move the grinding chips, thus facilitating the discharge of grinding chips and filtering through two adjacent filter plates, ensuring the continuous operation of grinding work.

[0021] (4) By setting up a moving component, a linear motor is used to move linearly along the slide rail, thereby driving the circular sleeve and grinding block to follow the movement through the support bar, so that the grinding block can perform three-dimensional grinding on the surface of the casting, thereby improving the grinding efficiency and effect.

[0022] (5) By setting up a clamping unit, the horizontal plate is pushed to move by the telescopic rod. The distance between the horizontal plates on both sides and the vertical plate can be adjusted by rotating. Thus, the casting can be clamped and fixed by the change of the spacing, so that the grinding process of the casting can be carried out stably. Attached Figure Description

[0035] The enclosure assembly 3 includes a rubber ring 31, which is made of a material that is pressure-resistant, wear-resistant, corrosion-resistant, and high-temperature resistant. One side of the outer surface of the rubber ring 31 is fixedly connected to the outer surface of the circular sleeve 1. A film 32 is fixedly connected to the outer surface of the rubber ring 31. The film 32 is made of a material that is elastic, tensile-resistant, fatigue-resistant, and resistant to high-temperature corrosion. An arc plate 33 is movably connected to the outer surface of the rubber ring 31. The arc plate 33 is made of a material that is pressure-resistant, wear-resistant, and high-temperature resistant, and one side is connected to the rubber ring 31 via an embedded hinge. A filter unit 34 is provided on the outside of the arc plate 33. The outer surface of the arc plate 33 is connected to the outer surface of the film 32.

The outer surface of one rotating frame 36 is fixedly connected to the outer surface of the arc plate 33, and the outer surface of the other rotating frame 36 is fixedly connected to the outer surface of the circular sleeve 1. By setting the shielding component 3, the distance between the arc plates 33 can be adjusted by the action of the push-pull rod 35 and the rotating frame 36 to shield the outside of the grinding area, thereby avoiding the splashing of grinding chips and allowing the grinding chips to be uniformly recycled and processed.

[0036] Example 3:

[0037] The filter unit 34 includes a fixed cylinder 341, which is made of a pressure-resistant, wear-resistant, and corrosion-resistant material.

The outer surface of plate 346 is movably connected to the interior of fixed cylinder 341. A discharge pipe 347 is connected through the interior of fixed cylinder 341, and a connecting pipe 348 is connected through the interior of fixed cylinder 341.

The retaining ring 349 is made of a pressure-resistant, wear-resistant, and corrosion-resistant material and is hollow inside. The retaining ring 349 is fitted on the outside of arc plate 33. A corrugated pipe 3410 is connected through the interior of retaining ring 349. One end of corrugated pipe 3410 is fixedly connected through the body of arc plate 33. By setting up a filter unit 34, the grinding chips can be continuously filtered using filter plate 346, filter cylinder 343, and blower 345, thus facilitating continuous grinding of castings. At the same time, the regulating motor 344 drives the filter cylinder 343 to rotate, causing the filter plate 346 to move the grinding chips, thus facilitating the discharge of grinding chips and filtration through two adjacent filter plates 346, ensuring the continuous operation of grinding.

[0038] Example 4:

[0039] The moving component 4 includes a base plate 41, with a clamping unit 42 on the outside of the base plate 41. The base plate 41 is located below the circular sleeve 1. Side plates 43 are fixedly connected to both sides of the outer surface of the base plate 41. A slide rail 44 is fixedly connected to the outer surface of the side plates 43. The slide rail 44 is made of a pressure-resistant and wear-resistant material. A linear motor 45 is slidably connected to the outer surface of the slide rail 44. The linear motor 45 is electrically connected to an external control circuit. A support bar 46 is fixedly connected to the outer surface of the linear motor 45. The outer surface of the support bar 46 is fixedly connected to the outer surface of the circular sleeve 1. By setting up the moving component 4, the linear motor 45 moves linearly along the slide rail 44, thereby driving the circular sleeve 1 and the grinding block 8 to move along the support bar 46. This allows the grinding block 8 to perform three-dimensional grinding on the surface of the casting, thereby improving the grinding efficiency and effect.

[0040] Example 5:

[0041] The clamping unit 42 includes two vertical plates 421, which are made of a pressure-resistant and wear-resistant material. The two vertical plates 421 are positioned above the base plate 41. Horizontal plates 422 are rotatably connected to both sides of the outer surface of each vertical plate 421. The horizontal plates 422 are also made of a pressure-resistant and wear-resistant material. Pins 423, made of a pressure-resistant and wear-resistant material, are rotatably connected to the bodies of both vertical plates 421. One end of each pin 423 is rotatably connected to a vertical bar 424. The outer surfaces of both vertical bars 424 are fixedly connected to the outer surface of the base plate 41. Abutment bars 425, made of a pressure-resistant and wear-resistant material, are fixedly connected to the outer surfaces of both horizontal plates 422. One side of the abutment bar... A telescopic rod 426 is movably connected to the outer surface of the 425. The telescopic rod 426 is made of hydraulic rod and is connected to an external control circuit. One end of the telescopic rod 426 is fixedly connected to the outer surface of one side plate 43, and a spring 427 is fixedly connected to the outer surface of the other side abutment 425. The spring 427 is made of tensile, corrosion-resistant and fatigue-resistant material. One end of the spring 427 is fixedly connected to the outer surface of the other side plate 43. By setting a clamping unit 42, the telescopic rod 426 pushes the horizontal plate 422 to move. The distance between the two horizontal plates 422 and the vertical plate 421 can be adjusted by rotation. Thus, by changing the distance, the casting can be clamped and fixed so that the grinding process of the casting can be carried out stably.

[0042] Example 6: This example combines Examples 1 to 5. It utilizes rotary grinding and linear motion to achieve three-dimensional grinding. By enclosing the grinding area, the efficiency and effect of the grinding work are improved. Furthermore, the continuous filtration of grinding chips enhances the continuity of casting grinding.

[0043] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0044] During operation, the casting to be ground is first placed between the two side plates 43, passing through the inside of the sleeve 1 and the rotating ring 2. Simultaneously, the casting's shape ensures that its end is positioned between the two horizontal plates 422, or fitted onto the outside of the horizontal plates 422. Then, the output end of the telescopic rod 426 extends, driving one side of the horizontal plate 422 to move via the abutment bar 425. Through the action of the vertical plate 421, the other side of the horizontal plate 422 moves synchronously in the opposite direction. By reducing the distance between the two horizontal plates 422 and increasing the distance between their ends, the casting's outer side is ground. The clamp or internal support clamps and fixes the workpiece, while the other side abutment 425 stretches the spring 427 to facilitate the reset of the horizontal plate 422. Then, the output end of the electric push rod 7 extends, causing the grinding block 8 to contact the surface of the casting. At the same time, the output end of the push-pull rod 35 extends, causing the arc plate 33 to rotate and the other ends of multiple arc plates 33 to move closer to each other. Simultaneously, the film 32 rebounds to cover the outside of the casting. Subsequently, the drive motor 12, linear motor 45, and fan 345 are energized and work synchronously. First, the drive motor 12 passes through the gear ring 10 and gear 11. The meshing of the ring 9 causes the rotating ring 2 and the electric push rod 7 to rotate, thereby causing the grinding block 8 to grind the surface of the casting. Next, the linear motor 45 moves linearly along the slide rail 44, causing the circular sleeve 1 to drive the grinding block 8 to follow the movement, thus enabling three-dimensional grinding of the casting. Furthermore, the blower 345 draws air from the area enclosed by the arc plate 33 and the film 32 through the fixed cylinder 341, connecting pipe 348, retaining ring 349, and bellows 3410, causing the grinding debris to flow into the fixed cylinder 341 along with the air, and then into the filter plate 346 and filter cartridge. 343 filters the grinding shavings, while air is discharged to the outside of the solid cylinder 341 through the filter cartridge 343. The grinding shavings are located in the filtration area between two adjacent filter plates 346. Then, the motor 344 is adjusted to drive the filter cartridge 343 to rotate, so that the filter plates 346 carry the grinding shavings to one end of the discharge pipe 347. The grinding shavings are then uniformly collected and processed through the discharge pipe 347, and the grinding shavings continue to be filtered through the adjacent filtration area. By repeating the above steps, the casting can be continuously and efficiently ground, and the handling of grinding shavings is facilitated.
