Description

Technical Field

[0001] The utility model relates to the technical field of mechanical safety and protection, in particular to a sawing machine cutting protection device. Background Technique

[0002] A sawing machine is a machine tool used for cutting various materials, mainly achieving material cutting through the reciprocating or rotary motion of a saw blade or a saw band. Sawing machines are widely used in industries such as metal processing, wood processing, and plastic processing, and can accurately cut materials according to required sizes and shapes.

[0003] The existing sawing machine structure mainly consists of a workbench and a cutting device. The workbench is a platform for carrying materials to be cut, such as steel plates and steel pipes. The cutting device is responsible for performing the cutting work. Among them, the saw band, as a widely used cutting tool, is particularly suitable for cutting long materials. The saw band can use its sufficient length to press down to a specific depth to complete the cutting operation. However, during the cutting process, metal chips generated will fly everywhere, and if these flying metal chips accidentally come into contact with people or objects, they may cause injuries.

[0004] Therefore, it is necessary to design a sawing machine cutting protection device. Content of the Utility Model

[0005] In order to overcome the shortcoming that metal chips generated during the cutting process will fly everywhere, the utility model provides a sawing machine cutting protection device.

[0006] A sawing machine cutting protection device includes a frame, a driving motor, a sliding plate, a lead screw, a nozzle, and a piston. The driving motor is arranged at the bottom of the frame, the lead screw is arranged at the output end of the driving motor, the sliding plate is threadedly arranged on the lead screw, the nozzle is arranged on the top of the sliding plate, and the piston is arranged on both sides of the top of the nozzle.

[0007] More preferably, it further includes sliding inclined plates, first return springs, fixed rods, and a sliding frame. The sliding inclined plates are both slidably arranged on the left and right sides inside the sliding plate, first return springs are arranged between the sliding inclined plates and the sliding plate, the fixed rods are both slidably arranged on the upper left and right sides of the frame, and the sliding frame is arranged between the rear ends of the two fixed rods.

[0008] More preferably, it further includes fixing blocks, and the fixing blocks are arranged on the left and right sides of the frame.

[0009] More preferably, it further includes second return springs, and second return springs are arranged at the sliding connection between the fixed rods and the frame.

[0010] More preferably, the left and right sides inside the sliding plate are of a vacuum structure.

[0011] More preferably, the bottom of the sliding inclined plate is designed to be inclined.

[0012] The beneficial effects and remarkable progress of the present utility model lie in that:

[0013] The present utility model drives the screw rod to rotate through a driving motor. Under the action of the screw rod, the sliding plate will rise to block the side of the sawing machine workbench. During the cutting operation of the sawing machine, it can effectively prevent metal chips from splashing and improve the safety of the cutting operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following further illustrates the technical solution with specific embodiments. It should be noted that: The words indicating directions such as up, down, left, and right mentioned in this article are only for the positions of the shown structures in the corresponding drawings. The serial numbers assigned to the components in this article itself, for example: first, second, etc., are only used to distinguish the described objects and do not have any sequential or technical meanings. And as used in this application: connection, coupling, unless otherwise specified, all include direct and indirect connection (coupling).

[0021] Embodiment: A sawing machine cutting protection device, please refer to Figures 1 to 5, including a frame 1, fixed blocks 2, a driving motor 3, a sliding plate 4, a lead screw 5, a spray head 6, pistons 61, sliding inclined plates 7, a first return spring 8, fixed rods 9, a sliding frame 10 and a second return spring 11. Fixed blocks 2 are connected to both the left and right sides of the frame 1. The fixed blocks 2 are used as connecting components for this protection device. A driving motor 3 is fixedly installed at the center position of the bottom of the frame 1 through bolts. The output shaft of the driving motor 3 is connected to a lead screw 5 through a bearing. A sliding plate 4 is connected to the lead screw 5 through threads. The sliding plate 4 is located inside the frame 1 and slides through the top of the frame 1. The left and right sides inside the sliding plate 4 are of a vacuum structure. A spray head 6 is installed on the top of the sliding plate 4. Pistons 61 are arranged on both the left and right sides at the top of the spray head 6. Sliding inclined plates 7 are slidably connected to both the left and right sides inside the sliding plate 4. The sliding inclined plates 7 are in contact with the inner wall of the frame 1. First return springs 8 are connected between the sliding inclined plates 7 and the sliding plate 4. The bottom of the sliding inclined plate 7 is designed with an inclined surface. Fixed rods 9 are slidably connected to both the upper left and right sides of the frame 1. A sliding frame 10 is connected between the rear ends of the two fixed rods 9. Second return springs 11 are connected to the sliding joints between the fixed rods 9 and the frame 1.

[0022] When the protection device needs to be used, this protection device should first be installed on both sides of the sawing machine workbench through the fixed blocks 2. After installation, start the driving motor 3 to drive the lead screw 5 to rotate. Under the action of the lead screw 5, the sliding plate 4 will rise inside the frame 1 to block the side of the sawing machine workbench, thereby improving the operation safety. During this process, the sliding inclined plates 7 are located inside the sliding plate 4 and the first return springs 8 are compressed. When the sliding plate 4 moves upward, the connected sliding inclined plates 7 will also rise synchronously. When the bottom of the sliding inclined plate 7 contacts the inner corner of the frame 1, the inclined surface design at its bottom will cause the sliding inclined plate 7 to expand outward under the elastic force of the first return spring 8, so as to expand the shielding area and better protect the operator from flying objects. At the same time, as the sliding plate 4 rises, the connected spray head 6 also moves upward synchronously. Before the sawing machine cutting operation starts, the spray head 6 can be started in advance to spray water mist on the working area, effectively reducing dust generation and improving the working environment. When the spray head 6 moves upward and contacts the sliding frame 10, the sliding frame 10 will slide backward due to the inclined surface design at the bottom of the spray head 6, driving the fixed rods 9 to slide together, resulting in the compression of the second return spring 11. In this way, the sliding frame 10 is located below the spray head 6, which can prevent the water sprayed by the spray head 6 from entering the inside of the frame 1 and avoid damage to the internal components.
