[0001] The invention relates to the field of copper strip processing, in particular to a copper strip flame cutting device. Background Art

[0002] Copper strip is a metal component primarily used in the production of electrical components, lamp holders, battery caps, buttons, seals, and connectors. It is primarily used for conductive, thermal, and corrosion-resistant materials. Examples include electrical components, switches, washers, gaskets, vacuum devices, radiators, conductive base materials, and various parts such as automotive radiators, heat sinks, and cylinder plates. During the production process, copper strip often requires cutting. There are many cutting methods, selected based on specific needs, and flame cutting is one such method.

[0003] At present, when processing copper strips through flame cutting, the high temperature of flame cutting will melt the edges of the copper strip cuts, forming irregular slag. If not cleaned in time, the slag will adhere to the cut position of the steel strip after cooling, resulting in uneven cut positions of the copper strip, affecting the processing effect of the copper strip. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a copper strip flame cutting device, which overcomes the deficiencies of the prior art.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a copper strip flame cutting device, comprising a processing box with an opening on one side, and placing plates are fixedly connected to the symmetrical inner side walls on both sides of the processing box, and a movable plate is provided in the processing box above the two placing plates, and an electric slide is fixedly installed at the lower end of the movable plate, and a lifting assembly for driving the movable plate to move in a vertical direction is installed in the processing box, and a flame cutting machine is slidably installed on the electric slide, and the flame cutting machine is located above the two placing plates, and a pressing assembly for fixing the copper strip is installed on the movable plate, and a connecting pipe is fixedly connected to the inner side wall of one side of the processing box, and a connecting rod is slidably connected to the connecting pipe, and the other end of the connecting rod passes through the pipe mouth of the connecting pipe and extends outward and is fixedly connected to a cleaning frame with a U-shaped cross-section, the interior of the cleaning frame is set as a cavity, and the cleaning frame is located in the middle of the two placing plates, and the cleaning frame matches the thickness of the copper strip.

[0006] By adopting the above technical solution, when in use, the steel strip to be cut is placed on the two placing plates and passes through the cleaning frame, and the position to be cut is moved to the bottom of the flame cutting machine. At this time, the movable plate is moved downward by the lifting component, and the cleaning frame is moved to move and remove from the surface of the steel strip. The downward movement of the movable plate will drive the flame cutting machine to move downward. When the flame cutting machine moves to the specified position, the flame cutting machine is started, the flame cutting machine will emit a flame, and then the flame cutting machine is moved horizontally by the electric slide rail to flame cut the surface of the steel strip. When the steel strip cutting is completed, the flame cutting machine is reset by the lifting component. At this time, the cleaning frame is moved again. After the cleaning frame contacts the surface of the steel strip, the slag on the surface of the steel strip is pushed and cleaned to ensure the flatness of the steel strip incision position. Through the above structure, the slag at the steel strip incision position can be cleaned in time after the steel strip cutting is completed to prevent the slag from adhering to the steel strip surface after cooling, thereby improving the steel strip cutting effect.

[0007] Optionally, the lifting assembly includes a cylinder fixedly mounted on the top outer end of the processing box, and the piston end of the cylinder passes through the top of the processing box and extends downward and is fixedly connected to the movable plate.

The two movable plates will move horizontally opposite to each other under the force. The movement of the movable plate will apply a force to the second transmission rod. The second transmission rod will apply a force to the connecting plate under the force. The connecting plate will drive the cleaning frame to move horizontally and longitudinally under the force to separate the cleaning frame from the surface of the steel strip. When the pressing tube moves upward, the cleaning frame will be reset to clean the cutting position of the cut steel strip.

[0014] By adopting the above technical solution, when the cleaning frame cleans the slag, the slag will accumulate at the end position of the cleaning frame, and the filter will filter the slag. At this time, the movement of the movable plate will drive the push plate to move, and the movement of the push plate will drive the sealing piston to move through the piston rod. The movement of the sealing piston will squeeze the air inside the air cylinder, and the compressed gas will enter the cleaning frame through the air pipe and then be discharged from the vent, thereby making it easy for the slag to separate from the filter.

[0015] Optionally, a guide rod is fixedly connected to the inner side wall of the processing box, the guide rod passes through the two movable plates, and the two movable plates are slidably connected to the guide rod.

When the movable plate moves downward, a force is applied to the movable plate through the pressing tube and the first transmission rod, so that the movable plate drives the cleaning frame to move horizontally and longitudinally through the second transmission rod, so that the cleaning frame is separated from the steel strip surface, and then the flame cutting machine is moved horizontally by the electric slide rail, so that the flame cutting machine performs flame cutting on the surface of the steel strip. When the steel strip cutting is completed, the flame cutting machine is reset by the cylinder, and at the same time, the cleaning frame is reset, and after contacting the steel strip surface, the slag on the surface of the steel strip is pushed and cleaned, so as to ensure the flatness of the steel strip incision position.
