Description

Technical Field

[0001] This utility model relates to the field of lost foam casting hammerhead technology, and in particular to a surface grinding device for lost foam casting hammerhead. Background Technology

[0002] Lost foam casting, also known as "dry sand casting" or "negative pressure casting," primarily uses expandable polystyrene as raw material to create a foam mold. The mold bundles are effectively and rationally combined according to the volume of the sand box, coated with a special coating, dried, and then buried in a negative pressure sand box with dry sand free of moisture, binders, and other additives. After micro-vibration to compact the foam, molten metal is poured in under appropriate negative pressure. When high-temperature molten iron is poured into the mold, the foam instantly vaporizes. After the molten metal completely solidifies, a high-precision casting is obtained in one step. To polish the lost foam casting hammer, a surface polishing device is needed.

[0003] A search revealed Chinese patent CN220994125U, which discloses a sandblasting machine body, an observation window, and a base. This invention, by incorporating a wiping mechanism and a cleaning mechanism, can simultaneously clean sand and dust adhering to the glass plate inside the observation window using the wiping mechanism, and remove larger and more stubborn sand and dust particles from the glass plate using the cleaning mechanism. This further improves the wiping effect of the wiping mechanism, solving the problem that sand and dust adhere to the observation window of the sandblasting machine during the cleaning process, obstructing the user's view and causing inconvenience. It also addresses the issue that when larger or more stubborn sand and dust adheres to the glass plate, the wiping mechanism, which uses a brush to wipe the glass plate flat, requires multiple wipings to completely remove these particles, thus affecting the wiping efficiency.

[0004] The above-mentioned patent has the following shortcomings: the surface polishing devices for lost foam casting hammers currently available on the market are not very convenient to use and cannot block the sparks that occur during polishing.

[0005] Therefore, we provide a surface polishing device for lost foam casting hammerheads. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned technical problems by providing a surface grinding device for lost foam casting hammers, which effectively blocks grinding sparks during grinding.

[0007] In view of this, the present invention provides a surface polishing device for a lost foam casting hammer, comprising a worktable, a support frame fixedly connected to the top of the worktable, a telescopic crossbar fixedly connected inside the support frame, a pressure plate fixedly connected to one end of the telescopic crossbar, a top motor fixedly connected to the bottom of the support frame, and a lifting top column fixedly connected to the output shaft of the top motor via a coupling.

[0008] A grinding disc is fixedly connected to the bottom of the lifting column, a limit frame is fixedly connected to the top of the workbench, a transparent sliding window is movably connected to one side of the limit frame, and a window handle is fixedly connected to one side of the transparent sliding window.

[0009] Preferably, a lifting sleeve block is fixedly connected to the bottom of the workbench, and a base is fixedly connected to the bottom of the lifting sleeve block.

[0015] Compared with the prior art, this utility model provides a surface grinding device for lost foam casting hammerheads, which has the following beneficial effects:

[0016] 1. This utility model, through the setting of a workbench, support frame, telescopic cross column, pressure plate, top motor, lifting top column, grinding disc, limiting frame, transparent sliding window and window handle, allows for the following operation: First, slide the transparent sliding window to the right using the window handle. Then, place the hammer head with the grinding surface facing upwards between the two pressure plates. The telescopic cross column extends, causing the pressure plate to press against the hammer head, thus fixing it in place. Slide the transparent sliding window to the left side of the device using the window handle. At this point, the top motor starts working, and the output shaft of the top motor rotates, driving the lifting top column and grinding disc to rotate. Simultaneously, the lifting top column extends, causing the grinding disc to contact the grinding surface, thereby completing the grinding of the hammer head's grinding surface. The transparent sliding window also blocks sparks from splashing during grinding, improving the safety of the device during operation, preventing injury to workers, increasing the overall utilization rate of the device, and facilitating operation by different personnel.

[0017] 2. This utility model, through the setting of a lifting sleeve block, base, support column, movable wheel, side bolt, side plate, and push handle, allows the device to retract when it needs to change its working position, so that the base does not contact the ground and the movable wheel contacts the ground. Then, by pushing the handle, the entire device is moved to the working position. At this time, the lifting sleeve block extends, so that the base contacts the ground and the movable wheel does not contact the ground, thereby giving the device good stability during operation. This facilitates the device to change between different working positions, provides a stable effect for the device, reduces the time required for device movement, improves the overall working speed, and speeds up the subsequent work process.

[0018] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0027] First, when using the device, slide the transparent sliding window 9 to the right using the window handle 10. Then, place the hammer head with the grinding surface facing up between the two pressure plates 4. The telescopic crossbar 3 extends, causing the pressure plates 4 to press against the hammer head, thus fixing the hammer head in place. Slide the transparent sliding window 9 to the left side of the device using the window handle 10. At this time, the top motor 5 starts working. The output shaft of the top motor 5 rotates, driving the lifting top column 6 and the grinding disc 7 to rotate. At the same time, the lifting top column 6 extends, causing the grinding disc 7 to contact the grinding surface, thus completing the grinding of the hammer head's grinding surface. The transparent sliding window 9 also blocks the splashing of sparks during grinding, improving the safety of the device during operation, avoiding injury to the workers, increasing the overall utilization rate of the device, and facilitating operation by different workers.

[0028] Example 2: Figures 1-4As shown, a surface polishing device for a lost foam casting hammerhead is preferably provided. A lifting sleeve block 11 is fixedly connected to the bottom of the worktable 1, and a base 12 is fixedly connected to the bottom of the lifting sleeve block 11. A support column 13 is fixedly connected to the bottom of the worktable 1, and the height of the support column 13 is less than the maximum height of the lifting sleeve block 11. A movable wheel 14 is fixedly connected to the bottom end of the support column 13, and there are four movable wheels 14 and four support columns 13. A side bolt 15 is movably connected to one side of the worktable 1, and a side plate 16 is movably connected to the outer wall of the side bolt 15.

A strip-shaped sliding opening is provided on the top of the worktable 1, and the strip-shaped sliding opening of the worktable 1 is located below the limiting frame 8.

[0029] First, when the device needs to change its working position, the lifting sleeve 11 retracts, so that the base 12 does not contact the ground, and the movable wheel 14 contacts the ground. Then, by pushing the handle 17, the entire device is moved to the working position. At this time, the lifting sleeve 11 extends, so that the base 12 contacts the ground, and the movable wheel 14 does not contact the ground. This makes the device have good stability when working, which facilitates the device to change to different working positions. It also provides a stable effect for the device, reduces the time required for the device to move, improves the overall working speed, and speeds up the subsequent work process.
