Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a rotary pipe cutting machine. Background Art

[0002] A pipe cutting machine, also known as a pipe cutting machine, is a professional equipment specially used for cutting metal pipes (such as steel pipes, copper pipes, aluminum pipes, etc.) and certain non-metallic pipes (such as plastic pipes, PVC pipes, etc.).

[0003] According to the different cutting methods, pipe cutting machines can be divided into many types, including manual pipe cutting machines, semi-automatic pipe cutting machines and fully automatic pipe cutting machines, as well as machines using different cutting technologies such as sawing, grinding, laser cutting, plasma cutting, etc.

[0004] The choice of pipe cutting machine depends on factors such as the material, diameter, wall thickness, cutting accuracy requirements and production efficiency requirements of the pipe. Correct selection of pipe cutting machine can greatly improve production efficiency, ensure cutting quality and reduce material waste.

[0005] Existing pipe cutting machines are usually of a single structure, that is, a frame has a clamping assembly for positioning the pipe to be processed and a cutting assembly for cutting the pipe to be processed. Since the cutting assembly is fixed in position on the frame, it can only cut pipes with fixed cuts, and its applicability is relatively poor. Summary of the invention

[0006] The purpose of the utility model is to provide a rotary pipe cutting machine with high applicability and compact structure in view of the above problems existing in the prior art.

[0007] The purpose of the utility model can be achieved through the following technical solutions:

[0008] A rotary pipe cutting machine comprises a frame, characterized in that it also comprises a clamping assembly, a cutting assembly and a connecting assembly, the clamping assembly is fixedly connected to the frame and the clamping assembly can position the pipe to be processed, the cutting assembly is connected to the frame through the connecting assembly, the cutting assembly has an operating end and an operating end, the operating end is adjacent to the clamping assembly and the operating end can cut the pipe to be processed at the clamping assembly, and the cutting assembly can swing relative to the frame after external force is applied to the operating end.

[0009] The rotary pipe cutting machine creatively connects the cutting assembly to the frame through a connecting assembly, and the cutting assembly is adjacent to the clamping assembly.

[0010] It can be seen that since the pipe to be processed is located at the clamping assembly, the cutting assembly can stably cut the pipe to be processed clamped by the clamping assembly.

[0011] Under the action of the connecting assembly, the entire cutting assembly can also swing around the frame. After the cutting assembly swings, the cutting assembly can cut the pipe fittings in a set cutting direction, thereby cutting out pipe fittings with cuttings in corresponding directions.

[0012] In the above-mentioned rotary pipe cutting machine, the clamping assembly includes a bracket, a fixed clip, a movable clip and a screw rod. The fixed clip is fixedly connected to one side of the bracket, the screw rod is axially fixed to the other side of the bracket and can rotate, the movable clip is connected to the screw rod, the fixed clip is opposite to the movable clip and a clamping portion for clamping the pipe to be processed is formed therebetween.

[0013] After applying external force to rotate the screw rod, the movable clamping piece can be moved closer to or away from the fixed clamping piece, thereby realizing the loosening and clamping operation of the pipe fitting.

[0014] Of course, the pipe can be stably clamped at the clamping portion.

[0015] In the above-mentioned rotary pipe cutting machine, the bracket has a transversely arranged guide rod, the above-mentioned movable clamp is fixedly connected to the slider, the above-mentioned guide rod is penetrated by the slider, the above-mentioned screw rod is penetrated by the slider and the two are threadedly connected.

[0016] Since the slider is connected to the guide rod, the slider can move smoothly relative to the fixed clip under the action of the guide rod.

[0017] During the continuous rotation of the screw rod, the movable clamping piece can be moved smoothly relative to the fixed clamping piece.

[0018] In the above-mentioned rotary pipe cutting machine, the number of the fixing clips is two and the inner ends of both are fixedly connected to the two sides of one end of the bracket, and there is a gap between two adjacent fixing clips.

[0019] The two fixing clamps are arranged in parallel. Since the two fixing clamps are in contact with the pipe to be processed, the clamping stability of the fixing clamps on the pipe to be processed can be effectively improved.

[0020] In the above-mentioned rotary pipe cutting machine, the number of the movable clamping pieces is two and the inner ends of the two movable clamping pieces are fixedly connected to the two sides of the slider, and there is a gap between two adjacent movable clamping pieces.

[0021] In the above-mentioned rotary pipe cutting machine, the two fixed clamping pieces are located in the gap between the two movable clamping pieces.

[0022] Such a structure can prevent the fixed clip from contacting the movable clip.

[0023] In the above-mentioned rotary pipe cutting machine, the connecting component includes a base plate, an indicator piece and a scale mark on a frame. The inner end of the base plate is hinged on the frame, the cutting component is fixedly connected to the outer end of the base plate, the scale mark is arranged in an arc shape, and the arc center of the scale mark is located at the hinge between the base plate and the frame. The upper end of the indicator piece is fixedly connected to the base plate, and the lower end of the indicator piece is adjacent to the scale mark.

[0024] The inner end of the base plate is hinged on the frame. Since the indicator sheet is adjacent to the scale mark, the angle of the base plate after swinging can be intuitively and accurately understood. Each scale mark of the scale mark is a specific angle digital mark.

[0025] In the above-mentioned rotary pipe cutting machine, the cutting assembly includes a guide cylinder, a knife rod, a guide strip and a handle. The guide cylinder is fixedly connected to the outer end of the base plate, the guide cylinder is horizontally arranged and the upper side of the guide cylinder has a penetrating guide opening along its axial direction. The knife rod matches the inner cavity of the guide cylinder and the knife rod is inserted into the guide cylinder. The guide strip is fixedly connected to the upper part of the knife rod and the guide strip is embedded in the guide opening. The handle is fixedly connected to the upper part of the guide strip.

[0026] Since the knife bar is connected in the guide cylinder, the knife bar can smoothly translate along the guide cylinder. The end of the knife bar is used to install a cutter for cutting pipe fittings.

[0027] At the same time, the guide strip on the knife bar is embedded in the guide opening of the guide cylinder. Such a structure can prevent the knife bar from rotating relative to the guide cylinder, and ultimately ensure that the cutter connected to the knife bar will not deflect.

[0028] In the above-mentioned rotary pipe cutting machine, a linear bearing is provided between the guide cylinder and the cutter rod.

[0029] Under the action of the linear bearing, the friction resistance between the tool rod and the guide cylinder is relatively small, ensuring that the tool rod can translate smoothly.

[0030] In the above-mentioned rotary pipe cutting machine, the guide strip matches the guide opening.

[0031] Such a structure can further prevent the tool bar from being deflected.

[0032] Compared with the prior art, the rotary pipe cutting machine can cut pipes with cuts at various angles because the position of the cutting assembly can be changed, and thus has a relatively high applicability.

[0033] At the same time, after the cutting component is adjusted, its swing angle can be timely understood through the scale mark. The adjustment is intuitive, easy to use, and has high practical value. BRIEF DESCRIPTION OF THE DRAWINGS
