Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing, in particular to an edge polishing and grinding device for a sheet metal part. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates, including shearing, punching / cutting / combining, folding, welding, riveting, splicing, forming, etc. Its most notable feature is that the thickness of the same part is consistent. The products processed by sheet metal technology are called sheet metal parts. The sheet metal parts referred to in different industries are generally different, and are mostly used as the name for assembly.

[0003] The burrs that appear on the edges of sheet metal parts during the production process, especially after forming, need to be polished by machines. The existing sheet metal edge polishing and grinding methods mainly rely on manual operation. However, the smoke and dust particles generated during the grinding process are easily inhaled by workers, which will increase safety hazards to workers. Therefore, we propose a sheet metal edge polishing and grinding device to solve the problems raised in the above background technology. Utility Model Content

[0004] The utility model aims to provide an edge polishing and grinding device for a sheet metal part to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for polishing and grinding the edges of sheet metal parts, comprising a chassis, a protective frame and an air inlet, wherein a protective frame is fixedly installed on the top of the chassis, air cooling devices are arranged on both sides of the protective frame, two groups of polishing components are fixedly installed on both sides of the top of the chassis, an air inlet is installed on the inner rear end of the protective frame, filters are equidistantly arranged inside the air inlet, and a negative pressure fan is arranged on the back of the air inlet through a pipeline.

[0006] When the staff uses the device to grind sheet metal parts, they need to start the polishing component and bring the sheet metal parts close to the polishing component for grinding. At this time, start the negative pressure fan. The operation of the negative pressure fan can generate negative pressure to allow air to enter the air inlet and be discharged by the negative pressure fan. The high-speed circulation of air can take away the metal powder generated by the grinding of the sheet metal parts and allow it to enter the air inlet. In this process, the dust is intercepted by the filter to prevent the powder from escaping and prevent the staff from inhaling too much, thereby reducing the safety hazards caused by long-term operation and improving the user experience.

[0007] Preferably, the filter adopts a refractory filter element, and the negative pressure fan adopts an axial flow fan.

[0008] The metal chips and dust produced by grinding have a certain temperature. Since the filter has good fire resistance, it can filter the metal chips and dust produced by grinding. The axial flow fan has the advantage of small size and is more suitable for use in the device.

[0009] Preferably, the polishing assembly consists of a motor and a polishing wheel, the motor is arranged inside the chassis, and the polishing wheel is arranged on the top of the chassis.

[0010] The motor can drive the polishing wheel to rotate at high speed, and the workpiece can be ground and polished by the high-speed rotating polishing wheel.

[0011] Preferably, a lighting device is provided above the interior of the protection frame.

[0012] When the lighting device is powered on, wind power can be generated, and gas can be blown toward the polishing component to cool the polishing component.

[0013] Preferably, two groups of inspection doors are installed above the front of the chassis, and two groups of universal wheels are fixedly installed on both sides of the bottom of the chassis.

[0014] The opening and closing of the inspection door makes it convenient for staff to inspect and maintain the internal components of the chassis, and the universal wheels make it convenient for staff to move the chassis to a designated location.

[0015] In summary, this application includes the following beneficial technical effects:

[0016] The utility model discloses that when the staff uses the device to grind the sheet metal parts, the negative pressure fan is started. The operation of the negative pressure fan can generate negative pressure, so that air enters the air inlet and is discharged by the negative pressure fan. The high-speed circulation of air can take away the metal powder generated by the grinding of the sheet metal parts and make it enter the air inlet. In this process, the dust is intercepted by the filter to prevent the powder from escaping and the staff from inhaling too much, which reduces the safety hazards caused by long-term operation and improves the user experience.

[0025] The working principle of the edge polishing and grinding device for sheet metal parts based on Example 1 is: when the staff uses the device to grind the sheet metal parts, it is necessary to start the polishing component 3 and bring the sheet metal parts close to the polishing component 3 for grinding. At this time, the negative pressure fan 402 is started. The operation of the negative pressure fan 402 can generate negative pressure to allow air to enter the air inlet 4 and be discharged by the negative pressure fan 402. The high-speed circulation of air can take away the metal powder generated by the grinding of the sheet metal parts and allow it to enter the air inlet 4.
