Description

Technical Field

[0001] This utility model belongs to the field of steel plate cutting, specifically a steel cutting device. Background Technology

[0002] Steel materials refer to workpieces made of steel, including steel plates or reinforcing bars. When processing steel plates, cutting devices are used to cut the steel plates to achieve the required dimensions.

[0003] When cutting steel plates, the steel plate is first placed on a support base, and the cutting tool is driven to rotate at high speed by a power component. During the rotation, the tool will contact the steel plate downwards, and the cutting operation is achieved by the high-speed rotation of the tool. However, in the existing technology, when the tool cuts the steel plate, the surface of the tool will generate high temperature due to high-speed rotation. Prolonged use at high temperature will easily cause damage. In addition, the rotation of the tool will cause debris to fly, which can easily cause injury to personnel and pollute the external environment, thereby reducing the cutting quality.

[0004] In summary, this utility model provides a steel cutting device to solve the above-mentioned problems. Utility Model Content

[0020] To better understand the technical content of this utility model, specific embodiments are described below in conjunction with the accompanying drawings. Various aspects of this utility model are described in this disclosure with reference to the accompanying drawings, which illustrate numerous illustrative embodiments. The embodiments of this disclosure are not necessarily defined to include all aspects of this utility model. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in this utility model are not limited to any particular implementation. Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0021] Example 1

[0022] like Figure 1-4 As shown, this is the first embodiment of the present invention. This embodiment provides a steel cutting device, including a cutting unit 1. A chip processing unit 2 is provided on one side of the cutting unit 1. The cutting unit 1 includes a bracket 11, and a placement plate 12 is fixedly connected to the bottom of the inner cavity of the bracket 11. A cylinder 13 is fixedly connected to the top of the inner cavity of the bracket 11, and a motor 14 is fixedly connected to the output end of the cylinder 13. A grinding wheel 15 is drivenly connected to the output shaft of the motor 14. The chip processing unit 2 includes a connecting box 21, and a centrifugal fan 22 is provided at the bottom of the connecting box 21. A filter frame 23 is movably connected to the lower end of the inner cavity of the connecting box 21. A connecting pipe 24 is connected to the top of the connecting box 21, and a cover 25 is connected to the other end of the connecting pipe 24. A graphite box 3 is fixedly connected to the back of the cover 25, and a coolant is provided in the inner cavity of the graphite box 3.

[0023] like Figure 1-4As shown, the steel plate can be placed on the placement plate 12. By turning on the motor 14, the output shaft of the motor 14 drives the grinding wheel 15 to rotate at high speed. At the same time, the cylinder 13 is turned on, and the output end of the cylinder 13 drives the motor 14 and the grinding wheel 15 to move downwards until the rotating grinding wheel 15 contacts the steel plate, thereby realizing the cutting operation of the steel plate. During the cutting, the debris will enter the inner cavity of the cover 25 with the force of the rotation of the grinding wheel 15. The cover 25 can intercept the debris. Then, the centrifugal fan 22 operates to generate negative pressure suction in the connecting box 21 and the connecting pipe 24, thereby drawing the debris into the cover 25. The debris is transferred to the inside of the connecting box 21 through the connecting pipe 24, and collected by the filter frame 23 to prevent debris from splashing and causing harm to the external environment or personnel. When the grinding wheel 15 rotates and generates high temperature, the graphite box 3 is connected to one side of the grinding wheel 15 through a bearing. The thermal conductivity of the graphite box 3 can absorb the heat on the grinding wheel 15 and transfer the heat to the external airflow or the coolant inside the graphite box 3 to exchange heat and cool the grinding wheel 15, thus preventing the grinding wheel 15 from being damaged due to continuous high temperature.

[0024] Example 2

[0025] Reference Figure 1 and 2 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0026] In this embodiment, one side of the centrifugal fan 22 is fixedly connected to the bracket 11, and the air inlet of the centrifugal fan 22 is connected to the connecting box 21. The cover 25 is fitted onto the surface of the grinding wheel 15, and one side of the cover 25 is fixedly connected to the motor 14. The back of the grinding wheel 15 is movably connected to the graphite box 3 through a bearing.

[0027] The upper part of the back of the graphite box 3 is connected to the injection tube 31, and the lower part of one side of the surface of the graphite box 3 is connected to the drain tube 32. Both the drain tube 32 and the injection tube 31 are movably connected to the surface of the round cap.

[0028] like Figure 1 and 2As shown, the centrifugal fan 22 is connected to the support 11 to ensure the stability of the centrifugal fan 22 during operation. At the same time, the centrifugal fan 22 is connected to the connecting box 21, so that the centrifugal fan 22 can generate negative pressure suction inside the connecting box 21 when it is operating, which facilitates the subsequent suction of debris. The cover 25 is fitted on the surface of the grinding wheel 15 to intercept the debris brought up by the rotation of the grinding wheel 15 and prevent debris from splashing. The graphite box 3 is connected to the grinding wheel 15, which facilitates the heat transfer and absorption of the grinding wheel 15 by the graphite box 3, realizing the subsequent heat exchange and cooling operation. The round cover can seal the liquid injection pipe 31 and the liquid drain pipe 32 to prevent external impurities from entering through the liquid injection pipe 31 and to prevent the coolant inside the graphite box 3 from being discharged through the liquid drain pipe 32. The liquid injection pipe 31 can inject coolant into the inner cavity of the graphite box 3, so that the graphite box 3 can work with the coolant to cool the grinding wheel 15. The liquid drain pipe 32 can drain and replace the coolant after long-term use.

[0029] Example 3

[0030] Reference Figure 3 and 4 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0031] In this embodiment, a guide bucket 211 is fixedly connected to the upper end of the inner cavity of the connecting box 21, and the filter frame 23 is located below the guide bucket 211.

[0032] A sealing strip 232 is fixedly connected to the front end of the surface of the filter frame 23, and the side of the sealing strip 232 away from the filter frame 23 contacts the connecting box 21.

[0033] A second magnet 231 is fixedly connected to the back of the filter frame 23, and a first magnet 212 is fixedly connected to the back of the inner cavity of the connecting box 21. The first magnet 212 and the second magnet 231 are in contact and are magnetically connected.

[0034] like Figure 3 and 4As shown, the guide bucket 211 is located at the upper end of the inner cavity of the connecting box 21 and above the filter frame 23. Therefore, after debris enters the inner cavity of the connecting box 21, it directly enters the guide bucket 211. The guide bucket 211 guides the debris to the inner cavity of the filter frame 23, allowing the filter frame 23 to collect the debris. By pulling the filter frame 23, the filter frame 23 drives the second magnet 231 to move, causing the second magnet 231 to gradually disengage from the first magnet 212, releasing the magnetic connection and facilitating filtration. When the filter screen 23 detaches from the inner cavity of the connecting box 21, debris inside the filter screen 23 can be removed and processed. Conversely, when the filter screen 23 enters the inner cavity of the connecting box 21, the filter screen 23 causes the second magnet 231 to come into contact with the first magnet 212, generating a magnetic connection. This ensures the firm connection between the filter screen 23 and the connecting box 21. At the same time, the filter screen 23 causes the sealing strip 232 to come into contact with the connecting box 21, thereby ensuring the sealing of the connection between the filter screen 23 and the connecting box 21 and preventing debris from flying out through gaps.

[0035] In use, the steel plate is first placed on top of the placement plate 12, which supports the steel plate. When cutting is required, the motor 14 is turned on, and the output shaft of the motor 14 drives the grinding wheel 15 to rotate at high speed. At the same time, the cylinder 13 is turned on, and the output end of the cylinder 13 drives the motor 14 and the grinding wheel 15 downward until the rotating grinding wheel 15 contacts the steel plate, thus realizing the cutting operation. The debris generated during cutting will enter the inner cavity of the cover 25 with the force of the rotating grinding wheel 15. The cover 25 can intercept the debris. At the same time as interception, the centrifugal fan 22 is turned on. The operation of the centrifugal fan 22 creates a negative pressure suction force between the connecting box 21 and the connecting pipe 24, which in turn draws the debris from the inside of the cover 25. The debris is drawn into the connecting box 21. During the drawing process, the flow of external air can be increased, which can initially cool the surface of 15. Then, the debris is guided into the filter frame 23 through the guide bucket 211. The filter frame 23 collects the debris, thereby preventing debris from splashing and causing harm to the external environment or personnel. When the grinding wheel 15 rotates at high speed and its surface generates high temperature, the graphite box 3 is connected to one side of the grinding wheel 15 through a bearing. The thermal conductivity of the graphite box 3 can absorb the heat on the grinding wheel 15 and transfer the heat to the external airflow or the coolant inside the graphite box 3 to exchange heat and cool the grinding wheel 15. This can effectively prevent the grinding wheel 15 from being damaged due to continuous high temperature.
