[0001] This utility model relates to the field of cutting devices, specifically to a cutting device for processing metal round tubes. Background Technology

[0002] The dimensions of round tubes are very wide. When using metal round tubes, the length of the tube can be cut according to the actual situation to facilitate use. Specialized cutting machines are required when cutting the length of round tubes.

[0003] A Chinese patent authorization announcement (CN215698394U) discloses a cutting device for processing metal round tubes. This device solves the problem that existing metal round tube processing methods often fail to cut the tubes effectively, thus affecting processing efficiency. The device includes a base plate with support blocks installed at each of the four corners of the top edge. A support plate is installed on top of each support block, and a positioning mechanism is mounted on the support plate. A cutting mechanism is also installed on the support plate, located to one side of the positioning mechanism. This invention facilitates easier cutting of metal round tubes during processing, thereby improving processing efficiency.

[0004] The above-mentioned processing device also has the following problems when in use: the above-mentioned processing device cannot cut metal round tubes to a fixed length when in use, which means that the cutting point of the round tube needs to be marked manually before cutting, making the operation process inconvenient.

[0005] Therefore, it is necessary to invent a cutting device for processing metal round tubes to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a cutting device for processing metal round tubes, so as to solve the problem that the processing device mentioned in the background art cannot achieve fixed-length cutting of metal round tubes during use, which leads to the need for manual marking of the cutting point of the round tube before cutting, resulting in a relatively inconvenient operation process.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for processing metal round tubes, comprising a base, wherein a sliding channel is reserved inside the base, and a round tube is slidably installed inside the sliding channel; an arched frame is fixedly connected to the top wall of the base, and a cylinder is fitted into the top of the arched frame, and a cutter is installed at the output end of the cylinder; an end plate is slidably installed inside the sliding channel, and the end plate is threadedly connected to the tail of the base via a threaded rod; a forward moving component reserved inside the base pushes the round tube to slide; and an oil cavity is reserved inside the base, and an oiling component is provided inside the oil cavity to assist the movement of the forward moving component.

[0008] Preferably, the forward-moving component includes a motor fixedly connected to the outer wall of the base, and the output shaft of the motor is drivenly connected to a threaded rod II, and the threaded rod II is rotatably connected to the interior of the pre-reserved movable cavity inside the base to ensure stable rotation of the threaded rod II.

[0009] Preferably, the forward moving component further includes a sliding block that is slidably connected to the movable cavity. The sliding block is threadedly connected to the threaded rod two, and a smooth rod is slidably installed inside the sliding block. The end of the smooth rod is fixedly connected to the inner wall of the movable cavity, and the smooth rod and the threaded rod two are arranged parallel to each other to ensure smooth operation of the sliding block.

[0010] Preferably, the forward moving component further includes a connecting plate fixedly connected to the sliding block, and an abutment plate fixedly connected to the top of the connecting plate. The connecting plate and the abutment plate are slidably engaged with the vertical groove and the sliding channel, respectively. The abutment plate is in contact with the end of the round tube, and the movement of the sliding block causes the abutment plate to move and push the round tube.

[0011] Preferably, the oiling assembly includes a plug that is slidably connected to the oil chamber, wherein the plug contacts a frustum that is fixedly connected to the inside of the oil inlet groove in the sliding block by a connecting rod.

[0012] Preferably, the plug is composed of a pointed cone, a rod fixedly connected to the pointed cone, and a disc fixedly connected to the top of the rod, from bottom to top. The pointed cone matches the oil outlet inside the oil cavity and seals the oil outlet. The pointed tip of the lower end of the pointed cone is in contact with the top of the sliding block and achieves a sliding connection. The outer ring of the rod is movably fitted with a spring. The two ends of the spring are fixedly connected to the top wall of the base and the disc. The spring applies pressure to cause the plug to block the oil outlet.

[0013] Preferably, the oil inlet groove is inverted conical in shape and is connected to the threaded groove reserved inside the sliding block. A gap is provided between the oil inlet groove and the truncated cone to facilitate the lubricating oil to enter the threaded groove through the oil inlet groove to lubricate the threaded rod and ensure smooth subsequent movement of the sliding block.

[0014] Preferably, the top of the frustum protrudes beyond the top of the sliding block, facilitating the frustum's movement to lift the block and perform the oiling operation.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] When it is necessary to control the quantitative cutting of the round tube, the end plate can be moved inside the sliding channel by twisting the threaded rod one. This makes it easy to control the distance between the end plate end wall and the cutter. The distance between the end plate end wall and the cutter is the final quantitative cutting length of the round tube. The motor is started to drive the rotation of the threaded rod two. The sliding block slides inside the movable cavity, which drives the abutment plate to move inside the sliding channel and pushes the round tube placed inside the sliding channel. The other end of the round tube abuts against the end plate. This makes it easy to control the quantitative cutting of the round tube. The subsequent oiling assembly helps the sliding block and the threaded rod two to connect more smoothly. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-5 The cutting device for processing metal round tubes shown includes a base 1, a sliding channel 2 reserved inside the base 1, and a round tube 3 slidably installed inside the sliding channel 2. An arched frame 4 is fixedly connected to the top wall of the base 1, and a cylinder 5 is fitted into the top of the arched frame 4. A cutter 6 is installed at the output end of the cylinder 5. An end plate 7 is slidably installed inside the sliding channel 2, and the end plate 7 is threadedly connected to the tail of the base 1 through a threaded rod 8. A forward moving component 9 reserved inside the base 1 pushes the round tube 3 to slide. An oil cavity 10 is reserved inside the base 1, and an oiling component 11 is provided inside the oil cavity 10 to assist the movement of the forward moving component 9.

[0027] During use, when it is necessary to control the quantitative cutting of the round tube 3, the end plate 7 can be moved inside the sliding channel 2 by twisting the threaded rod 8. This facilitates the control of the distance between the end wall of the end plate 7 and the cutter 6. The distance between the end wall of the end plate 7 and the cutter 6 is the final quantitative cutting length of the round tube 3. The starting motor 901 drives the rotation of the threaded rod 902, which in turn causes the sliding block 904, which is threaded to the threaded rod 902, to slide inside the movable cavity 908 under the limiting action of the smooth rod 903. The top of the sliding block 904 moves through the abutment plate 906, which is fixedly connected to the connecting plate 905. The abutment plate 906 moves inside the sliding channel 2 and pushes the round tube 3 placed inside the sliding channel 2. The other end of the round tube 3 abuts against the end plate 7, which facilitates the control of the quantitative cutting of the round tube 3.

[0028] The forward-moving component 9 includes a motor 901 fixedly connected to the outer wall of the base 1, and the output shaft of the motor 901 is driven by a threaded rod 902. The threaded rod 902 is rotatably connected to the interior of the movable cavity 908 reserved inside the base 1, ensuring that the motor 901 drives the threaded rod 902 to rotate. The forward-moving component 9 also includes a sliding block 904 slidably connected to the movable cavity 908. The sliding block 904 is threadedly connected to the threaded rod 902, and a smooth rod 903 is slidably installed inside the sliding block 904. The end of the smooth rod 903 is fixedly connected to the inner wall of the movable cavity 908, and the smooth rod 903 is arranged parallel to the threaded rod 902 to ensure smooth operation of the sliding block 904.

[0029] The start motor 901 drives the rotation of the threaded rod 902, which in turn causes the sliding block 904, which is threadedly connected to the threaded rod 902, to slide inside the movable cavity 908 under the limiting action of the smooth rod 903.

[0030] The forward moving component 9 also includes a connecting plate 905 fixedly connected to the sliding block 904, and an abutment plate 906 fixedly connected to the top of the connecting plate 905. The connecting plate 905 and the abutment plate 906 are respectively slidably engaged with the vertical groove 907 and the sliding channel 2. The abutment plate 906 is in contact with the end of the round tube 3. The movement of the sliding block 904 causes the abutment plate 906 to move and push the round tube 3 to move.

[0031] The sliding block 904 slides inside the movable cavity 908. The top of the sliding block 904 moves through the abutment plate 906, which is fixedly connected to the connecting plate 905. The abutment plate 906 moves inside the sliding channel 2 and pushes the round tube 3 placed inside the sliding channel 2.

[0032] The oiling assembly 11 includes a plug 111 that is slidably connected to the oil chamber 10. The plug 111 contacts the frustum 114 that is fixedly connected to the oil inlet groove 113 in the sliding block 904 via a connecting rod. The plug 111 consists of a pointed cone, an insert rod fixedly connected to the pointed cone, and a disc fixedly connected to the top of the insert rod from bottom to top. The pointed cone matches the oil outlet inside the oil chamber 10 and seals the oil outlet. The pointed tip of the lower end of the pointed cone is attached to the top of the sliding block 904 and slidably connected. A spring 112 is movably fitted on the outer ring of the insert rod. The two ends of the spring 112 are fixedly connected to the top wall of the base 1 and the disc. The spring 112 applies pressure to cause the plug 111 to block the oil outlet.

[0033] The oil inlet groove 113 is inverted conical in shape and is connected to the threaded groove reserved inside the sliding block 904. There is a gap between the oil inlet groove 113 and the truncated cone 114 to facilitate the lubricating oil to enter the threaded groove through the oil inlet groove 113 to lubricate the threaded rod 902 and ensure the smooth movement of the sliding block 904. The top of the truncated cone 114 protrudes from the top of the sliding block 904, which facilitates the movement of the truncated cone 114 to lift the block 111 to achieve the oiling operation.

[0034] When the threaded rod 902 needs to be oiled, the same operation steps as above are followed. The rotation of the threaded rod 902 drives the sliding block 904 to move to below the oil outlet of the oil chamber 10. When the inclined surface of the truncated cone 114 contacts the tip of the bottom of the block 111 and moves, it can lift the block 111. In this way, the gap between the block 111 and the oil outlet facilitates the lubricating oil to drip into the oil inlet groove 113 to achieve oiling. The oil outlet is located at a specific distance, which can avoid the truncated cone 114 being opposite to the oil outlet when pushing the round tube 3. At the same time, the bottom wall of the oil chamber 10 is inclined to ensure smooth oil flow.

[0035] The above description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
