Description

Technical Field

[0001] This application relates to the technical field of environmental protection cutting, and particularly relates to an environmentally friendly sheet material cutting method. Background Art

[0002] Sheet materials such as stainless steel plates, aluminum plates, steel plates, and laminated plates are widely used in fields such as production equipment, household appliances, and furniture decoration.

[0003] However, in the existing cutting work of sheet materials such as stainless steel plates, aluminum plates, steel plates, and laminated plates, a large amount of dust, waste chips, etc. will be generated during the cutting process. The existing cutting equipment lacks effective dust removal measures, which not only easily pollutes the environment but also affects the physical health of operators. In view of this, those skilled in the art urgently need to develop an environmentally friendly sheet material cutting equipment and method to meet more actual use requirements. Summary of the Invention

[0004] The main purpose of this application is to provide an environmentally friendly sheet material cutting method, aiming to solve the above technical problems.

[0005] To achieve the above purpose, this application proposes an environmentally friendly sheet material cutting method, including the following steps:

[0006] S1: Place the sheet material on the loading and rolling device located at the upper rear side of the frame;

[0007] S2: Start the longitudinal movement driving device, and then drive the clamping and pushing device to move forward from the rear to clamp the rear edge of the sheet material;

[0008] S3: The longitudinal movement driving device drives the clamping and pushing device to continue moving forward, and pushes the clamped sheet material forward to the cutting position behind the rotary dust-proof device;

[0009] S4: When the sheet material reaches the cutting position, start the pressing device located at the upper rear side of the rotary dust-proof device, and the pressing device moves downward to press on the upper surface of the sheet material;

[0010] S5: Start the moving cutting device located at the lower rear side of the pressing device. The moving cutting device transversely cuts the pressed sheet material. At the same time, the upper dust suction device located above the moving cutting device and the lower dust suction device located below the moving cutting device are both started synchronously. Then, the upper dust suction device absorbs the dust and waste chips flying upward during the cutting process, and the lower dust suction device absorbs the dust and waste chips settling downward;

[0011] S6: After cutting is completed, the moving cutting device resets, the pressing device lifts upward to release the pressing on the sheet material, and the upper dust suction device and the lower dust suction device continue to operate;

[0012] S7: The longitudinal movement driving device drives the clamping and pushing device to continue moving forward, and then pushes the blank plate formed by the cutting work forward, so as to push the blank plate out of the rotary dust-proof device (600) and the discharge port in sequence;

[0013] S8: After the blank plate is completely pushed out, it falls onto the feeding and conveying device located at the front lower side of the discharge port. The feeding and conveying device starts and conveys the blank plate to the next process station;

[0014] S9: Repeat steps S3 to S8 until all the plates are cut;

[0015] S10: Reset and shut down all devices, and wait for the next plate cutting work.

Subsequently, through the transverse cutting function of the moving cutting device and the stable pressing effect of the downward pressing device, the accuracy and consistency during the cutting process are ensured, and the cutting error is reduced.

[0129] S1: Place the sheet on the loading and conveying device 100 located at the upper rear side of the frame 100;

[0130] S2: Start the longitudinal movement driving device 200, and then drive the clamping and pushing device 300 to move forward from the rear, so that the clamping and pushing device 300 clamps the rear edge of the sheet;

[0131] S3: The longitudinal movement driving device 200 drives the clamping and pushing device 300 to continue moving forward, and pushes the clamped sheet forward to the cutting position behind the rotary dust-proof device 600;

[0132] S4: When the sheet reaches the cutting position, start the pressing device 400 located at the upper rear side of the rotary dust-proof device 600, and the pressing device 400 moves downward to press on the upper surface of the sheet;

[0133] S5: Activate the mobile cutting device 500 located at the lower rear side of the pressing device. The mobile cutting device 500 performs a transverse cut on the pressed sheet material. Meanwhile, the upper dust suction device 700 located above the mobile cutting device 500 and the lower dust suction device 800 located below the mobile cutting device 500 are both activated synchronously. Subsequently, the upper dust suction device 700 absorbs the dust and waste chips that fly upward during the cutting process, and the lower dust suction device 800 absorbs the dust and waste chips that settle downward.

[0134] S6: After the cutting is completed, the mobile cutting device 500 resets, and the pressing device 400 lifts upward to release the pressing on the sheet material. The upper dust suction device 700 and the lower dust suction device 800 continue to operate.

[0135] S7: The longitudinal movement drive device 200 drives the clamping and pushing device 300 to continue moving forward, and then pushes forward the sheet material blank formed after the cutting work is completed, so as to push the sheet material blank out of the rotary dust protection device 600 and the discharge port 1002 in sequence.

[0136] S8: After the sheet material blank is completely pushed out, it falls onto the feeding and conveying device 900 located at the front lower side of the discharge port 1002. The feeding and conveying device 900 is activated and conveys the sheet material blank to the next process station.

[0137] S9: Repeat steps S3 to S8 until all the sheet materials are cut.

[0138] S10: Reset and shut down all devices, and wait for the next sheet material cutting work.
