Description

Technical Field

[0001] This utility model belongs to the field of metal cutting technology, and in particular relates to a metal cutting device with self-cleaning function. Background Technology

[0002] Metal cutting is a process that uses physical or chemical methods to divide metal materials into the required shapes and sizes. It is widely used in the manufacturing industry to produce parts, components, etc. Common processes include mechanical cutting, thermal cutting, and chemical cutting. Each process is selected based on the type of metal, thickness, and precision requirements. The selection of the process must take into account cost, efficiency, and processing quality to meet the needs of different industries.

[0003] Metal chips are generated during the cutting process of metal materials. These metal chips adhere to the processing platform, making it easy for subsequent metal materials entering the equipment to slip during cutting, thereby affecting the cutting accuracy of the equipment. To address this, we propose a metal cutting device with a self-cleaning function. Utility Model Content

[0004] The purpose of this invention is to provide a metal cutting device with a self-cleaning function. Specifically, by rotating two turntables, the protrusion drives the rocker arm to swing left and right, causing the slider to move along the slide rail and the scraper to move on top of the grid plate. This scraper's displacement pushes debris into the square holes of the grid plate, ultimately causing the debris to leave the grid plate. This prevents debris from adhering to the inside of the device and causing metal material to easily shift, thus ensuring the accuracy of the cutting. It solves the problem that existing metal cutting processes generate metal debris that adheres to the processing platform, causing subsequent metal material entering the device to easily slip during cutting, thereby affecting the cutting accuracy.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a metal cutting device with self-cleaning function, including a cutting mechanism for cutting metal materials. The cutting mechanism includes two turntables and a gear housing.

[0052] One specific application of this embodiment is as follows: When in use, first place the metal material at the top center of the grid plate 111, then start the laser cutter 147 to cut the metal material, then turn off the equipment and take out the cut metal product;

[0053] Next, the cleaning fluid container is connected to the booster pump 145, and the cleaning fluid is delivered into the nozzle 142 through the buffer tank 144 and the conduit 143, and then sprayed downwards through the nozzle 142 onto the top outer wall of the grid plate 111.

[0054] Next, the motor 139 is started, causing the output end of the motor 139 to drive the left gear 133 to rotate, and through meshing, drive the right gear 133 to rotate. The right gear 133 drives the two synchronous pulleys 135 through the synchronous belt, so that both synchronous pulleys 135 are in a rotating state, and the two turntables 1151 installed on the rounded corner back plate 112 on the back rotate. When the turntables 1151 rotate, they will pull the rocker arm 116 to rotate through the protrusion 1152, and the slider 117 at the bottom of the rocker arm 116 will drive the scraper 118 to move horizontally along the slide rail 113, pushing the debris into the grid hole at the top of the grid plate 111. These debris will pass through the grid hole and enter the collection assembly 12.

[0055] Finally, these debris will be guided into the collection box 124 along the arc surface of the inner circular guide plate 123. When the collection box 124 is full, the square-round pin is pulled out from the protrusion 1261 and protrusion 2 1262. Then, the hatch 1212 is opened and the debris is taken out. Then, the equipment is reset and new metal material is placed at the top center of the grid plate 111 to start the next round of production and processing.
