Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, and in particular to a device for grinding the extrusion marks on the surface of aluminum alloy workpieces. Background Technology

[0002] Extrusion marks refer to linear marks or patterns formed on the surface of a workpiece during metal processing, especially when materials like aluminum alloys are extruded through a die. These marks are caused by friction and pressure as the material passes through the holes or gaps of the die under high pressure. Extrusion marks make the surface of the workpiece uneven and rough, affecting its visual appearance. Grinding can remove extrusion marks, making the surface of the workpiece smooth and flat, and improving its aesthetics.

[0003] However, existing grinding equipment generates high temperatures in both the grinding head and the workpiece during the grinding process, which can accelerate the wear of the grinding head and also cause the workpiece to soften and deform. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0005] A device for grinding extrusion marks on the surface of aluminum alloy workpieces, comprising:

[0006] A workbench, wherein a fixed frame is provided on one side of the top of the workbench;

[0007] Multiple sets of branch pipes are arranged in a ring array on the top of the fixed frame, and a water tank is connected to the top of the multiple sets of branch pipes.

[0008] A grinding assembly includes an electric push rod fixedly mounted on a fixed frame, a movable plate disposed at the bottom of the electric push rod, and a grinding machine mounted at the bottom of the movable plate. A piston is slidably disposed inside a branch pipe, and a connecting rod is fixedly connected to the bottom of the piston. The bottom of the connecting rod passes through the fixed frame and extends to the bottom of the fixed frame. One end of the connecting rod extending to the bottom of the fixed frame is fixedly connected to the movable plate. A water outlet is disposed on the branch pipe and below the piston, with the water outlet facing the grinding machine. The electric push rod drives the movable plate to move downward, controlling the connecting rod to move the piston to the bottom of the water outlet, thereby opening the water outlet.

[0009] As an improvement to the above technical solution, the water outlet component includes multiple sets of nozzles fixedly inserted into the movable plate and corresponding to the number and position of the branch pipes. A connecting pipe is provided on the branch pipe below the piston, and the end of the connecting pipe away from the branch pipe is connected to the nozzle.

[0010] As an improvement to the above technical solution, an air filling pipe is connected to one side of the water tank.

[0011] As an improvement to the above technical solution, multiple sets of through holes are provided on the workbench, a filter screen is fixedly installed inside the workbench, a circulation pipe is connected to the side wall of the workbench below the filter screen, the top of the circulation pipe is connected to the water tank, and a water pump is installed on the circulation pipe.

[0012] As an improvement to the above technical solution, the filter screen is inclined, and a dirt removal hole is provided on one side of the workbench at the lowest end of the filter screen. A sealing plug adapted to the dirt removal hole is installed on the side wall of the workbench.

[0013] The beneficial effects of this utility model are:

[0014] The grinding machine is lowered by an electric push rod to ensure stable contact with the workpiece and to grind the extrusion marks. The piston moves with the grinding machine. When grinding begins, the water outlet is opened to cool and lubricate the grinding area and the workpiece surface, effectively reducing grinding heat, preventing workpiece overheating and deformation, reducing grinding machine wear, and improving grinding quality and efficiency. When grinding ends, the piston moves up to close the water outlet, avoiding unnecessary waste of coolant and improving resource utilization efficiency. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] A device for grinding extrusion marks on the surface of aluminum alloy workpieces, comprising:

[0020] Workbench 10, with a fixing frame 30 provided on one side of the top of the workbench 10;

[0021] Multiple sets of branch pipes 22 are arranged in a ring array on the top of the fixed frame 30, and a water tank 21 is connected to the top of the multiple sets of branch pipes 22;

[0022] A grinding assembly 40 includes an electric push rod 43 fixedly mounted on the fixed frame 30, a movable plate 41 disposed at the bottom of the electric push rod 43, and a grinding machine 42 mounted at the bottom of the movable plate 41. A piston 45 is slidably disposed inside the branch pipe 22. A connecting rod 46 is fixedly connected to the bottom of the piston 45. The bottom of the connecting rod 46 passes through the fixed frame 30 and extends to the bottom of the fixed frame 30. One end of the connecting rod 46 extending to the bottom of the fixed frame 30 is fixedly connected to the movable plate 41. A water outlet is disposed on the branch pipe 22 and below the piston 45. The water outlet end of the water outlet faces the grinding machine 42. The electric push rod 43 drives the movable plate 41 to move downward and controls the connecting rod 46 to move the piston 45 to the bottom of the water outlet, so that the water outlet opens.

[0023] Specifically, when grinding of an aluminum alloy workpiece is required, the electric push rod 43 is activated, driving the moving plate 41 to move downwards. The grinding machine 42, mounted at the bottom of the moving plate 41, gradually approaches the surface of the aluminum alloy workpiece as the moving plate 41 descends, until it contacts and begins grinding the extrusion marks on the workpiece surface. While the electric push rod 43 drives the moving plate 41 downwards, the connecting rod 46 drives the piston 45 to move synchronously downwards within the branch pipe 22. Before the piston 45 moves below the water outlet, the water outlet is closed, preventing water from flowing out of the water tank 21. When the piston 45 moves below the water outlet... When the water outlet is below the water tank, the water in the tank flows through the branch pipe 22 and the water outlet to the grinder 42, cooling and lubricating the grinding part of the grinder 42 and the surface of the aluminum alloy workpiece. This reduces the heat generated during grinding, prevents the workpiece surface from overheating and deforming, and also reduces the wear of the grinder 42, improving grinding quality and efficiency. When the grinder 42 moves upward away from the workpiece and grinding is no longer needed, the piston 45 moves above the water outlet, closing the water outlet and avoiding unnecessary waste of coolant. This ensures that the coolant is only used during grinding operations, improving resource utilization efficiency.

[0024] In one embodiment, the water outlet includes multiple sets of nozzles 44 fixedly inserted into the movable plate 41, corresponding to the number and position of the branch pipes 22. A connecting pipe 47 is provided on the branch pipe 22 below the piston 45. The end of the connecting pipe 47 away from the branch pipe 22 is connected to the nozzle 44. Water in the water tank 21 flows under pressure through the branch pipes 22 and the connecting pipe 47 to the nozzles 44, and then the nozzles 44 evenly spray the water onto the grinding area of ​​the grinder 42 and the surface of the aluminum alloy workpiece, achieving cooling and lubrication functions. The position of the nozzles 44, in conjunction with the grinder 42, ensures that the water accurately acts on the areas requiring cooling and lubrication, improving the cooling and lubrication effect. The connecting pipe 47 guides the water in the branch pipe 22 to the nozzles 44, providing a channel for water flow.

[0025] In one embodiment, an air supply pipe 23 is connected to one side of the water tank 21. Its main function is to supply air into the water tank 21 to increase the air pressure inside the water tank 21. When air is supplied into the water tank 21, the air pressure inside the water tank 21 increases. After the piston 45 moves to the bottom of the water outlet and opens the water outlet channel, the water in the water tank 21 can be sprayed out from the nozzle 44 more smoothly through the branch pipe 22 and the connecting pipe 47 under the action of air pressure, ensuring that the coolant has sufficient pressure and flow, thereby better cooling and lubricating the grinding part.

[0026] The workbench 10 has multiple sets of through holes 11. A filter screen is fixedly installed inside the workbench 10. A circulation pipe 20 is connected to the side wall of the workbench 10 and below the filter screen. The top of the circulation pipe 20 is connected to the water tank 21. A water pump is installed on the circulation pipe 20. During the grinding process, the coolant sprayed from the nozzle 44 cools and lubricates the workpiece and the grinding machine 42. It carries the grinding debris and other impurities onto the workbench 10 and then enters the interior of the workbench 10 through the through holes 11. The filter screen intercepts metal debris, dust, and other impurities, preventing them from entering the circulation pipe 20 and avoiding blockage of the circulation system or contamination of the liquid in the water tank 21. This ensures the cleanliness of the coolant so that it can be recycled. The circulation pipe 20 and the water pump transport the filtered coolant in the workbench 10 back to the water tank 21, improving the utilization rate of the coolant, reducing costs, and also reducing environmental pollution.

[0027] In one embodiment, the filter screen is inclined, and a dirt removal hole is provided on one side of the workbench 10 at the lowest end of the filter screen. A sealing plug adapted to the dirt removal hole is installed on the side wall of the workbench 10. The filter screen is inclined so that the filtered impurities can slide naturally down the inclined surface of the filter screen to the lowest end of the filter screen under the action of gravity. When it is necessary to clean the impurities, simply open the sealing plug and the impurities can be discharged from the dirt removal hole.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
