Description

Technical Field

[0001] The invention relates to the technical field of metal processing, in particular to a metal pipe cutting device with a burr removal function. Background Art

[0002] Metal cutting is a material removal and forming method in the metal forming process, and it still accounts for a large proportion in today's mechanical manufacturing. Using a high-speed rotating grinding wheel to cut steel is a relatively common cutting method. The grinding wheel cutter is light, flexible, simple and convenient to use, and is widely used in various occasions, especially on construction sites and in interior decoration. It is mainly used to cut some small-diameter square tubes, round tubes, special-shaped tubes, etc.

[0003] When cutting steel pipes, the front and back of the tool are subjected to normal force and friction. Therefore, a large amount of heat is usually generated during the processing. This heat is usually accompanied by a large amount of burrs. Therefore, after the processing is completed, the burrs need to be removed manually, which not only wastes manpower and material resources, but also brings about the problem of low productivity. At the same time, during the production process, it is also necessary to pay attention to the specifications and shapes of the steel pipes. The cutting force required for them is different, and these problems need to be avoided. Summary of the Invention

The internal swing ring frame will also fully limit the moving direction of the steel pipe. When the steel pipe enters the feed crawler group, the feed crawler group will clamp the steel pipe and move it until it is transported to the designated position. The cutting assembly will cut the steel pipe. While cutting, the pressurized spray gun supplies water. Under the action of the guiding assembly, the water flow will impact the cutting seam of the steel pipe at a high speed to knock off the burrs on it. During the cutting process, the clamping frame and the clamping sub-frame will stably support the steel pipe. The cut steel pipe is lifted away, and the debris in the cutting process will enter the filter assembly with the water flow and be recycled.

[0006] The feed bed includes a feed base bed and an auxiliary base bed, which are slidingly connected to the auxiliary base bed. An auxiliary hydraulic rod is provided on the feed base bed, and the output end of the auxiliary hydraulic rod is connected to the auxiliary base bed. The limiting bracket is rotationally connected to the auxiliary base bed. A clamping piece is provided in the swinging ring frame, and a smooth pulley is rotatably connected to the clamping piece. When cutting, the steel pipe passes through the swinging ring frame, and the clamping piece on the swinging ring frame will contact the steel pipe, and the smooth pulley on the clamping piece ensures the normal movement of the steel pipe. The auxiliary hydraulic rod cooperates with the feed base bed to adjust the position between the auxiliary base bed and the feed base bed, so as to adapt to steel pipes of various shapes.

[0007] Adjustment columns are respectively provided at both ends of the swinging ring frame, and the adjusting column is rotationally connected to the limiting bracket. A trigger spring is provided in the limiting bracket, and the adjusting column presses against the trigger spring. A pressure switch is provided in the limiting bracket and the rotating end of the adjusting column. The pressure switch is electrically connected to the auxiliary hydraulic rod through a wire, and the trigger spring is in sliding contact with the pressure switch. When the steel pipe enters the swinging ring frame, the clamping piece will be attached to the steel pipe. During the transportation of the steel pipe, the shape of the steel pipe will affect the stability of the subsequent cutting, and the shape change will be captured by the swinging ring frame, and drive the adjusting column to rotate. The adjusting column will press against the trigger spring, and the pressure switch will be triggered, causing the auxiliary hydraulic rod to move, thereby causing the auxiliary machine tool and the feeding machine tool to offset, involving the steel pipe, and causing the steel pipe to return to the center, thereby making the steel pipe cutting smoother.

[0008] The feeding crawler group includes a feeding motor and a feeding rack. The feeding motor is arranged on the feeding rack, and the feeding rack is arranged in the cutting box. A feeding cam is arranged on the output end of the feeding motor. A feeding auxiliary wheel is rotated on the feeding rack. A capturing crawler is installed on the feeding cam and the feeding auxiliary wheel. A telescopic hydraulic rod is arranged in the cutting box. A sensing rack is arranged on the inlet end of the cutting box. The sensing rack is slidably connected to the cutting box. A sensing spring is sleeved on the sensing rack. The two ends of the sensing spring respectively press against the sensing rack and the cutting box. A sliding resistor is arranged in the cutting box. A slider is installed on the sensing rack. The slider and the sliding resistor The sliding resistor is electrically connected to the telescopic hydraulic rod through a wire. When the steel pipe enters the cutting box, the sensing frame will contact the sensing frame, and the sensing frame will drive the slider to slide on the sliding resistor. The sliding resistor cooperates with the slider to know the thickness of the steel pipe, and the sensing spring is responsible for the rebound of the sensing frame, and then controls the hydraulic cylinder on the feed frame to move and adapt to the current thickness of the steel pipe. The feed motor drives the feed cam to rotate, and the feed cam drives the feed secondary wheel to rotate synchronously under the transmission of the capture track, so that the steel pipe is stably delivered to the cutting position.

[0009] The cutting assembly includes a cutting frame, which is equipped with a cutting motor, a gearbox on the output end of the cutting motor, a cutting tool on the output end of the gearbox, a drainage cover on the gearbox, and a guide assembly on the drainage cover. When the steel pipe enters the cutting position, the cutting motor will transmit power to the gearbox, and the gearbox will transmit power to the cutting tool. The cutting tool will rotate and cut the steel pipe. The drainage cover can not only collect debris, but also provide power for the guide assembly.

[0010] A swing motor is provided in the cutting frame, and the swing motor is provided with a swing gear. A cutting groove is provided on the cutting frame, and the cutting frame is rotatably connected to the cutting groove. A limiting ring is provided in the cutting frame, and a plurality of sliding beads are hinged on the limiting ring. Teeth are provided on the cutting frame, and the teeth on the cutting frame are engaged with the teeth on the swing gear. The cutting motor is provided on the cutting frame. During the cutting process, the swing motor works, and the swing motor drives the swing gear to rotate. When the swing gear rotates, a cutting cylinder is installed at the same time, and the cutting cylinder drives the reduction gear to move, so that the cutting component can fully cut the steel pipe of different thickness. The rotation of the swing gear will drive the cutting frame to rotate, and the limiting ring limits the moving trajectory of the cutting frame.

Under the action of the moving cylinder and the closing gear, the process of the clamping frame and the clamping sub-frame is the same. At the same time, the movement process of the clamping frame is controlled by the data acquisition of the sensing frame. When vibration occurs, the vibration ring shakes on the detection column and contacts the sliding electrode ring, while the support plate supports the vibration ring. The higher the vibration frequency of the sliding electrode ring, the more unstable the current cutting state is. At this time, it is necessary to adjust the knife depth and feed speed to avoid accidents.

[0012] The guide assembly includes a guide box, which is arranged on the drainage hood. A friction wheel is arranged in the guide box, and the friction wheel is rotatably connected to the guide box.

The threads on the boosting disk will pressurize the water and air injected into the boosting chamber, and release them to form a high-pressure water-gas mixture, which may also be mixed with processing debris, to fully impact the incision of the steel pipe and remove burrs on the cut edge. At the same time, the use of a sunshade structure can also fully protect the cutting surface.

[0013] The boost chamber is provided with an injection port, and an extrusion piece is installed on the injection port.

At the same time, the injection pressure can also be adjusted by adjusting the contraction wedge groove.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention adopts a structural component with adaptive function. By cooperating with the moving state of the steel pipe during feeding, the current shape of the steel pipe is known.

[0016] 2. The present invention adopts a self-checking function for feeding, which controls the feeding degree by detecting the specifications of the steel pipe. At the same time, it uses the vibration feedback of the clamping frame and the clamping sub-frame to adjust the feed force and processing depth, which fully avoids the problem of deviation or breakage in steel pipe cutting due to different diameters and thicknesses of the steel pipe.

[0017] 3. The present invention adopts a moving burr removal component, which fully impacts the cutting surface by controlling the pressurization of cleaning liquid, gas and processing debris, reduces the generation of burrs, and thereby protects the flatness of the cutting surface and ensures the cleanliness of the tool.
