Description

Technical Field

[0001] This utility model belongs to the field of steel pipe cutting technology, specifically relating to a rotary shearing machine for processing stainless steel pipe fittings. Background Technology

[0002] Pipe fittings are a collective term for components in a piping system used for connection, control, direction change, flow diversion, sealing, and support. Materials include steel and plastic, with steel pipe fittings being specifically made of steel. In the processing and production of stainless steel pipe fittings, the pipe material needs to be cut to the required length for easier manufacturing.

[0003] In existing technologies, stainless steel pipes are primarily cut using cutting devices. However, most of these devices use saws or grinding wheels to perform linear cuts by pressing down from a single point on the pipe. While this method is fast, it easily results in burrs on the cut surface, requiring subsequent grinding. For example, utility model patent CN210548476U discloses a stainless steel pipe cutting device. This device includes a base, four sets of legs, a support mechanism, a power mechanism, and a control mechanism. Each of the four sets of legs has four mounting components mounted on its top, all installed at the bottom of the base. The support mechanism includes support rods and rocker arm assemblies. It also includes four sets of telescopic rods, an adjusting plate, an adjusting threaded rod, a rotating plate, an adjusting handle, a pressing plate, a positioning plate, a pushing plate, an L-shaped extrusion rod, and two sets of pushing springs. The left side of the pressing plate contains a pressing chamber.

[0004] Therefore, it is necessary to design a rotary shearing machine for processing stainless steel pipe fittings to reduce the generation of burrs on the cut. Utility Model Content

[0005] This utility model provides a rotary shearing machine for processing stainless steel pipe fittings to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rotary shearing machine for processing stainless steel pipe fittings includes a machine base, which includes a support base, a motor, and a jaw disc. The jaw disc is horizontally mounted on the top surface of the support base. The motor is mechanically connected to the jaw disc and drives the jaw disc to rotate. A cutting assembly includes a bracket and a circular blade. The bracket is mounted on the side of the support base where the jaw disc is mounted. The circular blade is rotatably mounted on the bracket. The circular blade is close to the clamping end of the jaw disc. The surface of the circular blade is parallel to the surface of the jaw disc.

[0008] As a further improvement to the technical solution, the base also includes a support block; the support block is disposed on the top surface of the support base; the support block is located directly below the axis of the claw disk.

[0009] As a further improvement to the technical solution, the side of the support block away from the support base has an arc-shaped structure.

[0010] As a further improvement to the technical solution, the base also includes ball bearings; the ball bearings are movably disposed on the side of the support block away from the support seat.

[0011] As a further improvement to the technical solution, the base also includes an L-shaped rod; the vertical end of the L-shaped rod is connected to the top surface of the support base; the horizontal end of the L-shaped rod is located directly above the axis of the claw disk.

[0012] As a further improvement to the technical solution, the ball bearing is movably disposed on the horizontal end of the L-shaped rod near the axis of the claw disk; the center of the ball bearing and the axis of the claw disk are on the same vertical plane.

[0013] As a further improvement to the technical solution, the base also includes a slide rail and a slider; the L-shaped rod is disposed on the top surface of the support base via the slide rail and the slider; the slide rail is disposed on the top surface of the support base; the length direction of the slide rail is consistent with the length direction of the claw disk axis; the slider is slidably connected to the slide rail; the vertical end of the L-shaped rod is connected to the slider.

[0014] As a further improvement to the technical solution, the vertical end of the L-shaped rod is rotatably connected to the slider.

[0015] As a further improvement to the technical solution, multiple support blocks are distributed in parallel at intervals along the length direction of the claw disk axis.

[0016] As a further improvement to the technical solution, the cutting assembly also includes a linear motion mechanism; the disc cutter is connected to the support via the linear motion mechanism; the movable end of the linear motion mechanism is rotatably connected to the disc cutter; and the end of the linear motion mechanism away from the disc cutter is connected to the support.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] Work style:

[0019] In use, one end of the pipe is placed into the clamping end of the claw disc, which holds the pipe end. The remaining part of the pipe is supported by the ball bearings of the support block. Simultaneously, the positions of the slider and L-shaped rod are adjusted according to the length of the pipe. The slider moves along the length of the slide rail, and then the horizontal end of the L-shaped rod is rotated so that the ball bearings on the horizontal end of the L-shaped rod contact the outer wall of the pipe. The linear movement mechanism is then activated, driving the disc cutter towards the pipe. The cutting edge of the disc cutter contacts the outer wall of the pipe. The motor is then started, driving the claw disc to rotate. The pipe rotates with the claw disc, and as the pipe rotates, its outer wall continuously changes contact points with the disc cutter. This is equivalent to the disc cutter rotating and cutting around the pipe, resulting in uniform cutting points and effectively reducing burrs on the pipe cut. As the cut deepens, the linear movement mechanism drives the disc cutter forward, ensuring proper cutting between the disc cutter and the pipe. Attached Figure Description

[0029] Example 1:

[0030] like Figures 1 to 4As shown, a rotary shearing machine for processing stainless steel pipe fittings includes a base 1 and a cutting assembly 2. The base 1 includes a support 11, a motor 12, and a jaw disc 13. The jaw disc 13 is horizontally rotatably mounted on the top surface of the support 11. The motor 12 is mounted on the support 11 and is mechanically connected to the jaw disc 13, driving the rotary disc 13 to rotate. The cutting assembly 2 includes a bracket 21 and a disc cutter 22. The bracket 21 is mounted on the side of the support 11 where the jaw disc 13 is mounted. The disc cutter 22 is rotatably mounted on the bracket 21. The disc surface of the disc cutter 22 is parallel to the disc surface of the jaw disc 13. The disc cutter 22 is close to the clamping end of the jaw disc 13. After the jaw disc 13 clamps the pipe 3, the disc cutter 22 contacts the outer wall of the pipe 3. It should be noted that the connection between the motor and the jaw disc is a conventional connection, and the specific model of the motor is not an improvement of this application and will not be described in detail here.

[0031] like Figures 2 to 4 As shown, preferably, the base 1 further includes a support block 14; the support block 14 is used to support the pipe 3 to ensure that the pipe 3 is horizontal; the support block 14 is located directly below the axis of the claw disk 13; the side of the support block 14 away from the support base 11 has an arc-shaped structure, which is adapted to the outer wall of the pipe 3; multiple support blocks 14 are distributed in parallel and at intervals along the length direction of the claw disk 13 to support the longer pipe 3.

[0032] like Figure 2 and Figure 3 As shown, preferably, the base 1 also includes a ball bearing 15; the ball bearing 15 is movably disposed on the side of the support block 14 away from the support base 11, the outer wall of the tube 3 contacts the ball bearing 15, the ball bearing 15 supports the tube 3, and the tube 3 rotates on the ball bearing 15, which can reduce the friction force on the tube 3.

[0033] like Figures 2 to 4 As shown, preferably, the base 1 further includes an L-shaped rod 16; the vertical end of the L-shaped rod 16 is connected to the top surface of the support base 11; the horizontal end of the L-shaped rod 16 is located directly above the axis of the claw disk 13 to press down on the tube 3 held by the claw disk 13; a ball bearing 15 is movably disposed on the side of the horizontal end of the L-shaped rod 15 near the axis of the claw disk 13; the center of the ball bearing 15 is on the same vertical plane as the axis of the claw disk 13, and the horizontal end of the L-shaped rod 15 presses down on the tube 3 through the ball bearing 15.

[0034] like Figures 2 to 4As shown, preferably, the base 1 further includes a slide rail 17 and a slider 18; the L-shaped rod 16 is disposed on the top surface of the support base 11 via the slide rail 17 and the slider 18; the slide rail 17 is disposed on the top surface of the support base 11; the length direction of the slide rail 17 is consistent with the length direction of the axis of the claw disk 13; the slider 18 is slidably connected to the slide rail 17, and the slider 18 slides along the slide rail 17; the vertical end of the L-shaped rod 16 is connected to the slider 18, and the L-shaped rod 16 moves with the slider 17 to adjust the position of the L-shaped rod 16 to accommodate pipes 3 of different lengths; optionally, the vertical end of the L-shaped rod 16 is rotatably connected to the slider 18 so that when placing the pipe 3, the orientation of the horizontal end of the L-shaped rod 16 can be rotated. After the pipe 3 is placed, the L-shaped rod 16 is rotated again so that the ball bearings 15 on the L-shaped rod 16 contact and press against the pipe 3. Since the length direction of the horizontal end of the L-shaped rod 16 and the rotation direction of the pipe 3 are in the same vertical plane, the rotation of the pipe 3 will not cause the L-shaped rod 16 to rotate.

[0035] like Figures 2 to 4 As shown, preferably, the cutting assembly 2 further includes a linear motion mechanism 23; the disc cutter 22 is connected to the bracket 21 via the linear motion mechanism 23; the movable end of the linear motion mechanism 23 is rotatably connected to the disc cutter 22, driving the disc cutter 22 to extend and retract; the end of the linear motion mechanism 23 away from the disc cutter 22 is connected to the bracket 21; the linear motion mechanism 23 can be an electric push rod or a cylinder, etc., and the linear motion mechanism 23 is equipped with a controller, which is electrically connected to the linear motion mechanism 23 and the motor 12, and controls the extension and retraction of the linear motion mechanism 23. It should also be noted that the connection method between the controller and the linear motion mechanism and the motor is a conventional connection, and the specific models of the controller and the linear motion mechanism are not improvements of this application and will not be elaborated here.

[0036] Work style:

[0037] In use, one end of the tube 3 is placed into the clamping end of the claw plate 13, which holds one end of the tube 3. The remaining part of the tube 3 is supported by the balls 15 of the support block 14. At the same time, the positions of the slider 18 and the L-shaped rod 16 are adjusted according to the length of the tube 3. The slider 18 moves along the length direction of the slide rail 17, and then the horizontal end of the L-shaped rod 16 is rotated so that the balls 15 on the horizontal end of the L-shaped rod 16 contact the outer wall of the tube 3. The linear movement mechanism 23 is then activated, which drives the disc cutter 22 toward the tube 3. The disc cutter 22 moves and its blade contacts the outer wall of the pipe 3. Then, the motor 12 is started, and the motor 12 drives the claw plate 13 to rotate. The pipe 3 rotates with the claw plate 13. As the pipe 3 rotates, its outer wall continuously switches the contact point with the disc cutter 22. This is equivalent to the disc cutter 22 rotating and cutting around the pipe 3. The cutting point is uniform, which effectively reduces the generation of burrs on the cut of the pipe 3. At the same time, as the cut of the pipe 3 continues to deepen, the linear movement mechanism 23 drives the disc cutter 22 to move forward, which fully ensures that the disc cutter 22 cuts the pipe 3.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
