Description

Technical Field

[0001] This utility model relates to the field of grinding mechanisms, specifically a grinding mechanism for a cemented carbide bar grinding equipment. Background Technology

[0002] Hard alloys are alloy materials made from hard compounds of refractory metals and binder metals through powder metallurgy. Tungsten carbide rods are a type of high-hardness, high-strength alloy material made primarily from hard alloy tungsten carbide, along with other precious metals and binder phases, and produced through powder metallurgy pressing and sintering. They are widely used in national production and processing sectors.

[0003] Polishing is a crucial step in the processing of cemented carbide bars. However, when wet polishing cemented carbide bars using existing grinding equipment, debris remains on the grinding wheel. This damages the outer surface of the bar when the wheel continues polishing, causing scratches and dents, significantly reducing the polishing effect and yield, and resulting in substantial losses.

[0004] The research objective of this utility model is to design a grinding mechanism for a cemented carbide bar grinding equipment to address the problems existing in the prior art. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a grinding mechanism for a cemented carbide bar grinding equipment, which can effectively solve the problems existing in the prior art.

[0006] The technical solution of this utility model is:

[0007] A grinding mechanism for a cemented carbide bar grinding device includes:

[0008] Base;

[0009] Several water storage devices are arranged sequentially on the machine base. Each water storage device includes a water tank and a partition that divides the water tank into a cleaning area and a separation area distributed vertically. The partition is inclined and has an opening on its lower side.

[0010] The conveying device includes a conveyor line that sequentially crosses several of the water tanks and is used to convey bars, and several guide wheels corresponding to the conveyor line and used to limit and guide the bars.

[0011] A plurality of grinding devices are provided, each corresponding to a plurality of water tanks. Each grinding device includes a grinding wheel driven to rotate by a rotary drive device for grinding the bar stock, a flip drive device for driving the grinding wheel to flip, and a spray device for spraying cooling water. The water tanks are used to receive cooling water, and the baffles are used to guide the alloy debris generated by the grinding wheel to the separation area for separation. The plurality of grinding devices alternately perform grinding or cleaning. During cleaning, the flip drive device is used to drive the grinding wheel to flip into the water body of the cleaning area, and the rotary drive device is used to drive the grinding wheel to rotate for cleaning.

[0012] Furthermore, the high side of the partition corresponds to the side of the rod that contacts the grinding wheel, and the low end of the partition is spaced apart from the inner wall of the water tank to form a material discharge gap. The low side is provided with a plurality of material discharge ports that connect the cleaning area and the separation area. The bottom of the water tank is provided with a discharge valve that connects the separation area and the outside and is used to discharge the alloy debris and cooling water. The alloy debris is guided by the partition and falls into the material discharge ports and the material discharge gap to enter the separation area and be separated.

[0013] Furthermore, the spraying device includes a plurality of first spraying ends for spraying the outer wall of the bar and a plurality of second spraying ends corresponding to one side of the partition and for spraying and scouring the partition; the alloy debris is guided by the partition and sprayed by the plurality of second spraying ends and falls into the discharge port and discharge gap to enter the separation area and is separated.

[0014] Furthermore, the partition is designed with a concave arc shape, the conveyor line is offset to the left half of the water tank, and the grinding wheel corresponds to the middle of the water tank and the middle of the partition.

[0015] Furthermore, the conveyor line includes a conveyor belt driven by a conveyor drive device, the outer side of the conveyor belt is recessed with a limiting groove for limiting and accommodating the bar, a plurality of guide wheels correspond to the left and top sides of the bar respectively, and the grinding wheel corresponds to the right side of the bar.

[0016] Furthermore, the number of water storage devices and grinding devices is set to two. The flipping drive device is located on the machine base, and the rotating drive device is suspended above the water tank and connected to the drive end of the flipping drive device through the rotating seat. The flipping drive device drives the rotating drive device and the grinding wheel to flip downward together through the rotating seat until the grinding wheel is immersed in the water body in the upper part of the water tank.

[0017] Therefore, the beneficial effects of this utility model are:

[0018] 1. By adding a water tank, several grinding devices alternately grind or clean the surface of the rod during wet grinding and polishing. During cleaning, a flipping drive device drives the grinding wheel to flip into the water in the cleaning zone, while a rotation drive device drives the grinding wheel to rotate and clean. This allows the grinding wheel to flip back into the cleaning zone after grinding for a period of time and rotate at high speed to rinse away any metal debris remaining on its surface. This avoids excessive alloy debris remaining on the grinding wheel surface, which could affect the subsequent grinding and polishing of the rod surface and prevent damage to the rod surface caused by grinding and polishing, resulting in scratches and dents. This improves the effect of continuous grinding and polishing of cemented carbide rods and ensures a high pass rate. Furthermore, the addition of baffles guides most of the alloy debris generated by the grinding wheel to the separation zone, preventing it from returning to the cleaning zone in large quantities. This ensures the purity of the water in the cleaning zone and ensures the effectiveness of the grinding wheel's rotation and cleaning in the cleaning zone. It also prevents excessive alloy debris in the cleaning zone from rendering the grinding wheel cleaning ineffective, thus improving the cleaning effect of the grinding wheel.

[0019] 2. By setting the material drop gap and drop opening, and corresponding to the side of the baffle plate on the side of the bar that contacts the grinding wheel, the distance between the grinding wheel and the lower side of the baffle plate after the grinding wheel rotates into the cleaning zone can be increased. This prevents the grinding wheel rotation from causing alloy debris in the separation zone to flow back. It also ensures that the alloy debris falling from the bar after grinding is fully guided by the tilt of the baffle plate and falls into the drop opening and gap to enter the separation zone for separation. This ensures that the alloy debris can fully slide into the separation zone and avoids excessive residue on the top of the baffle plate, thereby improving cleaning efficiency. The purity of the area; and, through the setting of the discharge valve, when the water in the tank is used for cleaning the grinding wheel, after a certain amount of alloy debris has accumulated in the separation area, the discharge valve can be opened during the grinding wheel's grinding period to drain the alloy debris and cooling water in the tank together, and then closed. This prevents alloy debris that has accumulated to a certain height from escaping into the cleaning area and affecting the cleaning effect of the grinding wheel. The interval between the grinding wheel's alternating grinding and cleaning, as well as the discharge interval of the discharge valve, can be adaptively adjusted according to specific circumstances.

[0020] 3. By setting the second spray end, turbulence is maintained at the top of the baffle, thereby ensuring that the falling alloy debris can be quickly flushed down the top of the baffle after contacting the turbulence. This improves the efficiency of the alloy debris falling into the separation zone through the discharge port and discharge gap. Furthermore, the formation of this turbulence can further prevent the alloy debris in the separation zone from flowing back into the cleaning zone, thus further ensuring the purity of the water in the cleaning zone.

[0021] 4. By recessing the partition, the central depth of the cleaning zone is expanded. Furthermore, by offsetting the conveyor line, the grinding wheel can be centered and positioned to correspond to the expanded depth of the cleaning zone. This ensures that the grinding wheel, which is flipped into the cleaning zone, is positioned at a certain distance from the lower side of the partition, preventing the rotation of the grinding wheel from carrying out alloy debris from the partition zone and improving the cleaning stability of the grinding wheel.

[0026] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0027] refer to Figure 1-4 A grinding mechanism for a cemented carbide bar grinding equipment, comprising:

[0028] Base 1;

[0029] A number of water storage devices 2 are arranged sequentially on the base 1. Each water storage device 2 includes a water tank 21 and a partition 22 that divides the water tank 21 into a cleaning area 211 and a partition area 212 that are distributed vertically. The partition 22 is inclined and has an opening on its lower side.

[0030] The conveying device 3 includes a conveying line 31 that sequentially crosses several of the water tanks 21 and is used to convey the rods, and several guide wheels 32 that correspond to the conveying line 31 and are used to limit and guide the rods.

[0031] A plurality of grinding devices 4 are provided, each corresponding to a plurality of water tanks 21. Each grinding device 4 includes a grinding wheel 41 driven to rotate by a rotation drive device 42 for grinding the bar stock, a rotation drive device 43 for driving the grinding wheel 41 to rotate, and a spray device 44 for spraying cooling water. The water tanks 21 are used to receive cooling water, and the partitions 22 are used to guide the alloy debris generated by the grinding wheel 41 to the partition area 212 for separation. Specifically, the grinding wheel 41 is a grinding wheel.

[0032] The above structure, through the addition of water tank 21, allows several grinding devices 4 to alternately grind or clean the surface of the bar during wet grinding and polishing. During cleaning, the flipping drive device 43 drives the grinding wheel 41 to flip into the water in the cleaning zone 211, and the rotation drive device 42 drives the grinding wheel 41 to rotate for cleaning. This allows the grinding wheel 41 to flip into the cleaning zone 211 after grinding for a period of time and rotate at high speed to rinse away the metal debris remaining on its surface. This avoids excessive alloy debris remaining on the grinding wheel surface, which could affect the subsequent grinding and polishing of the bar surface and prevent damage during grinding and polishing. The presence of scratches and dents on the surface of the rod improves the effect of continuous grinding and polishing of the cemented carbide rod and ensures a high pass rate. Furthermore, the addition of the partition 22 ensures that most of the alloy debris generated by the grinding wheel 41 is guided to the separation area 212 and separated, making it difficult for a large amount to return to the cleaning area 211. This ensures the purity of the water in the cleaning area 211, thereby ensuring the effective rotation and cleaning of the grinding wheel 41 in the water of the cleaning area 211. It also prevents the grinding wheel 41 from being ineffective due to excessive alloy debris in the water of the cleaning area 211, thus improving the cleaning effect of the grinding wheel 41.

[0033] To improve the purity of the cleaning zone 211, the higher side of the partition 22 corresponds to the side of the rod that contacts the grinding wheel 41. The lower end of the partition 22 is spaced apart from the inner wall of the water tank 21 to form a material discharge gap 221. The lower side is provided with several material discharge ports 222 connecting the cleaning zone 211 and the partition zone 212. The bottom of the water tank 21 is provided with a discharge valve connecting the partition zone 212 and the outside and used to discharge the alloy debris and cooling water. The above structure, through the setting of the material discharge gap 221 and the material discharge ports 222, and the fact that the higher side of the partition 22 corresponds to the side of the rod that contacts the grinding wheel 41, can increase the distance between the grinding wheel 41 after it is rotated into the cleaning zone 211 and the lower side of the partition 22, preventing the alloy debris in the partition zone 212 from flowing back due to the rotation of the grinding wheel 41. It also allows the alloy debris falling from the rod after grinding to be fully absorbed by the partition. After being tilted and guided by plate 22, the alloy debris falls into the discharge port 222 and the discharge gap 221 and enters the separation zone 212 for separation. This ensures that the alloy debris can fall into the separation zone 212 and be separated, avoiding excessive residue on the top of the partition plate 22, thereby improving the purity of the cleaning zone 211. Furthermore, by setting the discharge valve, the water in the water tank 21 can be used to clean one end of the grinding wheel 41. After a certain amount of alloy debris accumulates in the separation zone 212, the discharge valve can be opened during the grinding period of the grinding wheel 41 to drain the alloy debris and cooling water in the water tank 21 and then closed. This prevents the alloy debris that has accumulated to a certain height from escaping into the cleaning zone 211 and affecting the cleaning effect of the grinding wheel 41. The interval between the grinding wheel 41 grinding and cleaning and the discharge interval of the discharge valve can be adjusted adaptively according to specific circumstances.

[0034] To improve the efficiency of alloy scrap falling, the spraying device 44 includes several first spray ends 441 for spraying the outer wall of the rod and several second spray ends 442 corresponding to one side of the partition 22 and used for spraying and rinsing the partition 22. This structure allows the alloy scrap to be guided by the partition 22 and concentrated by the spray from the second spray ends 442, sliding down to the discharge port 222 and discharge gap 221 to enter the separation zone 212 and be separated. The second spray ends 442 maintain turbulence at the top of the partition 22, ensuring that the falling alloy scrap is quickly flushed downwards along the top of the partition 22 after contacting the turbulence. This improves the efficiency of the alloy scrap falling through the discharge port 222 and discharge gap 221 into the separation zone 212. Furthermore, the formation of this turbulence further prevents the alloy scrap in the separation zone 212 from flowing back into the cleaning zone 211, further ensuring the purity of the water in the cleaning zone 211.

[0035] To improve the cleaning stability of the grinding wheel 41, the partition 22 is designed with a concave arc shape, the conveyor line 31 is offset to correspond to the left half of the water tank 21, and the grinding wheel 41 corresponds to the middle of the water tank 21 and the middle of the partition 22. This structure, through the concave design of the partition 22, expands the central depth of the cleaning zone 211, and through the offset design of the conveyor line 31, allows the grinding wheel 41 to be centrally positioned and corresponding to the expanded depth of the cleaning zone 211. This ensures that the grinding wheel 41, when flipped into the cleaning zone 211, is positioned at a certain distance from the lower side of the partition 22, preventing the rotation of the grinding wheel 41 from carrying out alloy debris from the partition zone 212, thus improving the cleaning stability of the grinding wheel 41.

[0036] To improve the stability of the conveyed bar stock, the conveyor line 31 includes a conveyor belt 312 driven by a conveyor drive device 311. The outer side of the conveyor belt 312 is recessed with a limiting groove 3121 for accommodating and positioning the bar stock. A plurality of guide wheels 32 correspond to the left and top sides of the bar stock, respectively, and the grinding wheel 41 corresponds to the right side of the bar stock. Thus, the U-shaped conveyor belt 312 improves the stability of the bar stock conveying, and the guide wheels 32, grinding wheel 41, and conveyor belt 312, when pressed against the outer periphery of the bar stock during grinding, further enhance the stability of the bar stock's forward movement during grinding.

[0037] Specifically, there are two water storage devices 2 and two grinding devices 4. The flipping drive device 43 is mounted on the base 1, and the rotating drive device 42 is suspended above the water tank 21 and connected to the drive end of the flipping drive device 43 via a rotating seat 45. The flipping drive device 43 drives the rotating drive device 42 and the grinding wheel 41 to flip downwards together through the rotating seat 45 until the grinding wheel 41 is immersed in the water in the upper part of the water tank 21. The rotating seat 45 improves the connection stability between the flipping drive device 43 and the rotating drive device 42, thereby improving the stability of the grinding and cleaning by the grinding wheel 41.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
