Description

Technical Field

[0001] This utility model relates to the technical field of pipe cutting tools, and more specifically, to a chamfering tool for cutting pipes. Background Technology

[0002] After PVC solid-wall pipes are cut without chips, the plastic material undergoes plastic flow under the pressure of the cutting blade, causing material near the cut to be pushed towards the outer wall of the pipe, forming a raised, rolled edge. During sleeve installation, this raised rolled edge pushes the sealant away, resulting in a loose connection, reduced tensile strength at the joint, and a tendency for the connected pipes to detach under water hammer impact. Therefore, after cutting the pipes, the joints need to be chamfered before installation. Currently, chamfering of PVC pipes is done manually using a chamfering tool, trimming each pipe manually after cutting, which is labor-intensive and inefficient. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies where pipes need to be chamfered after cutting, and to provide a chamfering tool for cutting pipes that chamfers the cut edges of the pipes while cutting.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A chamfering tool for cutting pipes is provided, comprising a mounting assembly and a cutting mechanism, the cutting mechanism being disposed on the mounting assembly; it also includes a chamfering cutter, the chamfering cutter being disposed on the mounting assembly, the tip of the chamfering cutter being located on the cutting plane of the cutting mechanism.

[0005] This utility model discloses a chamfering cutter for cutting pipes. When pipe cutting is required, the mounting assembly is installed on the cutter holder of a planetary pipe cutter. The planetary pipe cutter is then started to cut the pipe. Simultaneously, the chamfering cutter chamfers the cut edge of the pipe. By setting the cutting mechanism and the chamfering cutter on the mounting assembly, and positioning the tip of the chamfering cutter on the cutting plane of the cutting mechanism, chamfering is achieved at both ends of the pipe during the cutting process.

[0006] Furthermore, the chamfering cutting tool has a first chamfer surface and a second chamfer surface, and the blade tip is located on the intersection line of the first chamfer surface and the second chamfer surface, which is located on the cutting plane of the cutting mechanism. By setting the first chamfer surface and the second chamfer surface, chamfering is performed on both sides of the cutting plane, that is, the cutting points of the two pipes, while cutting.

[0007] Furthermore, it also includes rollers, which are mounted on the mounting assembly and located on both sides of the chamfering cutter. By setting the rollers, they abut against the pipe during cutting, assisting in the feeding and pressing of the pipe, ensuring accurate cutting and chamfering positions.

[0008] Furthermore, it also includes an adjustment component, through which the mounting component is connected to the machine tool holder. By providing the adjustment component, the angles of the cutting mechanism and the chamfering cutter on the machine tool holder can be easily adjusted to accommodate pipes of different specifications.

[0009] Furthermore, the adjustment assembly includes a first connector, a first rotating shaft, a first fixing member, a second connector, a second rotating shaft, a second fixing member, and a connecting shaft. The first rotating shaft is rotatably connected to the first connector, and the first rotating shaft is fixedly connected to the first connector via the first fixing member. The second rotating shaft is rotatably connected to the second connector, and the second rotating shaft is fixedly connected to the second connector via the second fixing member. Both ends of the connecting shaft are connected to the first rotating shaft and the second rotating shaft, respectively. When adjusting the angle, the first and second fixing members are loosened, and the connecting shaft is rotated. The connecting shaft drives the first rotating shaft to rotate on the first connector, and the second rotating shaft to rotate on the second connector, thereby changing the connection angle between the first and second connectors, and consequently changing the angle of the cutting mechanism and the chamfering cutter on the machine tool holder, facilitating the cutting of pipes of different specifications.

[0010] Furthermore, the adjustment assembly also includes a third fixing member. The connecting shaft passes through the first rotating shaft and the second rotating shaft, and the connecting shaft is fixedly connected to the first rotating shaft and the second rotating shaft via the third fixing member. By allowing the connecting shaft to pass through the first rotating shaft and the second rotating shaft, the position of the connecting shaft relative to the first rotating shaft and the second rotating shaft can be changed during adjustment, which facilitates the cutting of pipes of different specifications and also facilitates the separation of the first connecting member and the second connecting member for maintenance.

[0011] Furthermore, the mounting assembly includes a device mounting block, a chamfering cutter mounting block, and a fourth fixing member. The cutting mechanism is mounted on the device mounting block, and the chamfering cutter is mounted on the chamfering cutter mounting block. The chamfering cutter mounting block is slidably connected to the device mounting block, and the chamfering cutter mounting block is fixedly connected to the device mounting block via the fourth fixing member. By allowing the chamfering cutter mounting block to slide with the device mounting block, the relative positions of the cutting mechanism and the chamfering cutter can be changed to adjust the chamfering effect and adapt to different types of pipes.

[0012] Furthermore, the chamfering cutter mounting block includes a mounting base and a pressure plate. The chamfering cutting cutter is located between the mounting base and the pressure plate. The chamfering cutting cutter is slidably connected to the mounting base, and the chamfering cutting cutter is fixedly connected to the mounting base via the pressure plate. The chamfering cutting cutter slides within the mounting base, allowing for fine-tuning of its position relative to the cutting mechanism to achieve the desired chamfering effect.

[0013] Furthermore, the mounting block of the device is provided with multiple mounting holes for connecting to the machine tool holder. By providing mounting holes for connection with the machine tool holder, the connection of the tool is made more stable; at the same time, providing multiple mounting holes facilitates adjustment of the installation position of the tool.

[0014] Furthermore, the cutting mechanism includes a mounting shaft and a cutting circular blade. The mounting shaft is rotatably connected to the mounting assembly, and the cutting circular blade is mounted on the mounting shaft. The cutting plane is the plane where the cutting edge of the cutting circular blade is located. In use, the mounting shaft is connected to the output end of the drive mechanism, and the drive mechanism drives the cutting circular blade to rotate via the mounting shaft for cutting.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. The present invention provides a chamfering tool for cutting pipes. By setting a cutting mechanism and a chamfering cutting tool on the mounting assembly, and positioning the tip of the chamfering cutting tool on the cutting plane of the cutting mechanism, the chamfering of the pipe is performed simultaneously during the cutting process.

[0016] 2. The present invention provides a chamfering tool for cutting pipes, which, by setting a first chamfering surface and a second chamfering surface, performs chamfering treatment on both sides of the cutting plane at the same time as cutting, that is, the cutting points of both pipes are chamfered at the same time as cutting.

[0017] 3. The present invention provides a chamfering tool for cutting pipes. By setting an adjustment component, the installation angle of the cutting mechanism and the chamfering cutting tool on the machine tool holder can be easily adjusted to accommodate pipes of different specifications.

Taking "A and / or B" as an example, it includes option A, option B, or an option that satisfies both A and B.

[0022] Example 1 This embodiment is a first embodiment of a chamfering tool for cutting pipes, such as... Figure 1 As shown, the device includes a mounting assembly 100 and a cutting mechanism 200, with the cutting mechanism 200 mounted on the mounting assembly 100. It also includes a chamfering cutter 300, mounted on the mounting assembly 100, with the tip of the chamfering cutter 300 located on the cutting plane of the cutting mechanism 200. Figure 3 As shown.

[0023] It also includes rollers 400, which are mounted on the mounting assembly 100 and located on both sides of the chamfering cutter 300. By setting the rollers 400, they abut against the pipe during cutting, assisting in feeding and pressing the pipe, ensuring accurate cutting and chamfering positions.

[0024] like Figure 3As shown, the mounting assembly 100 includes a device mounting block 110, a chamfering cutter mounting block 120, and a fourth fixing member 130. The cutting mechanism 200 is mounted on the device mounting block 110, and the chamfering cutter 300 is mounted on the chamfering cutter mounting block 120. The chamfering cutter mounting block 120 is slidably connected to the device mounting block 110, and the chamfering cutter mounting block 120 is fixedly connected to the device mounting block 110 via the fourth fixing member 130. By fixing the position of the cutting mechanism 200 with the device mounting block 110 and the position of the chamfering cutter 300 with the chamfering cutter mounting block 120, the relative positions of the cutting mechanism 200 and the chamfering cutter 300 can be changed to adjust the chamfering effect and adapt to different types of pipes.

[0025] like Figure 4 As shown, the device mounting block 110 is provided with multiple mounting holes 111 for connecting to the machine tool holder 600. By providing mounting holes 111 for connection with the machine tool holder 600, the connection of the tool is made more stable; at the same time, multiple mounting holes 111 are provided to facilitate adjustment of the installation position of the tool.

[0026] like Figure 5 As shown, the chamfering cutter mounting block 120 includes a mounting base 121 and a pressure plate 122. The chamfering cutting cutter 300 is located between the mounting base 121 and the pressure plate 122. The chamfering cutting cutter 300 is slidably connected to the mounting base 121. Specifically, a guide bearing can be provided on the mounting base 121, and the chamfering cutting cutter 300 is slidably connected to the mounting base 121 through the guide bearing. The chamfering cutting cutter 300 is fixedly connected to the mounting base 121 through the pressure plate 122. The chamfering cutting cutter 300 slides within the mounting base 121, allowing for fine adjustment of its position relative to the cutting mechanism 200 to accommodate different pipe diameters. The pressure plate 122 fixes the chamfering cutting cutter 300, preventing axial movement of the chamfering cutting cutter 300.

[0027] like Figure 5 As shown, the cutting mechanism 200 includes a mounting shaft 210 and a cutting circular blade 220. The mounting shaft 210 is rotatably connected to the mounting assembly 100. The cutting circular blade 220 is mounted on the mounting shaft 210, and the cutting plane is the plane where the cutting edge of the cutting circular blade 220 is located, that is, the tip of the chamfering cutting tool 300 is located on the plane where the cutting edge of the cutting circular blade 220 is located. In use, the mounting shaft 210 is connected to the output end of the drive mechanism, and the drive mechanism drives the cutting circular blade 220 to rotate for cutting via the mounting shaft 210. Specifically, in Figure 3 From this perspective, when cutting pipes, the straight line formed by the tip of the chamfering cutting tool 300 and the cutting edge of the circular cutting tool 220 are collinear.

[0028] The working principle of a chamfering tool for cutting pipes in this embodiment is as follows: When pipe cutting is required, the mounting assembly 100 is installed on the blade holder 600 of the planetary pipe cutter. The planetary pipe cutter is then started to cut the pipe. Simultaneously, the cutting mechanism 200 cuts the pipe while the chamfering cutter 300 simultaneously presses against the cut edge of the pipe, and also chamfers the cut edge. By setting the cutting mechanism 200 and the chamfering cutter 300 on the mounting assembly 100, and positioning the tip of the chamfering cutter 300 on the cutting plane of the cutting mechanism 200, chamfering is performed on the cut edge of the pipe during the cutting process, reducing the need for subsequent manual rework and chamfering. This cutting tool controls the cutting quality through bearings and precise tolerances, with a chamfer angle error of ≤0.5° and a burr-free cut, meeting the requirements for pipe socket connections and improving product quality. It is suitable for cutting PVC pipes of DN40-DN400mm specifications and supports various chamfering requirements from 15° to 45°. No separate chamfering machine is required, reducing equipment investment and manual rework chamfering processes, thus reducing labor costs by 50%.

[0029] Example 2 This embodiment is a second embodiment of a chamfering tool for cutting pipes. This embodiment is similar to the first embodiment, except that, as shown in the example... Figure 2 and Figure 3 As shown, the chamfering cutting tool 300 has a first chamfering surface 310 and a second chamfering surface 320. The blade tip is located on the intersection line of the first chamfering surface 310 and the second chamfering surface 320, and the intersection line is located on the cutting plane of the cutting mechanism 200. Specifically, when the chamfering tool for cutting pipes of this invention is installed on the tool holder 600 of a planetary pipe cutter, the planetary pipe cutter will drive the tool holder 600 to move circumferentially around the pipe to be cut while simultaneously feeding radially along the pipe. For Figure 3 The pipe on the left side has a first chamfered surface 310 that serves as the first primary flank face. The first primary flank face and the rake face together form the first primary cutting edge pair. Figure 3 The pipe on the left side is chamfered; for Figure 3 The pipe on the right side has a second chamfered surface 320, which serves as the second primary flank face. This second primary flank face and the rake face together form the second primary cutting edge. Figure 3 The pipe on the right side is chamfered. The blade tip is located on the cutting plane of the cutting mechanism 200, that is, at the cut-off point of the left and right pipes, which is the end of the pipe; that is, the chamfering is achieved by feeding radially from the end of the pipe.

[0030] By setting a first chamfer surface 310 and a second chamfer surface 320, chamfering is performed on both sides of the cutting plane, that is, the cutting points of the two pipes, simultaneously during cutting. Specifically, while the cutting mechanism 200 performs high-speed cutting, the chamfering cutting blade 300 above simultaneously performs chamfering. Figure 2 The first chamfered surface 310 and the second chamfered surface 320 form a 150° angled edge planing, chamfering each of the cut edges of the two pipes on the left and right sides of the cutting plane by 15°, achieving a double chamfering function while removing burrs, resulting in a smooth cut and uniform chamfer. This tool is not limited to a 15° chamfer; by changing the tilt angle of the first chamfered surface 310 and the second chamfered surface 320, it supports various chamfering requirements from 15° to 45°.

[0031] Example 3 This embodiment is the third embodiment of a chamfering tool for cutting pipes. This embodiment is similar to Embodiment 1, except that, as... Figure 1 and Figure 3 As shown, it also includes an adjustment component 500, and the mounting component 100 is connected to the machine tool holder 600 via the adjustment component 500. By setting the adjustment component 500, it is easy to adjust the angle of the cutting mechanism 200 and the chamfering cutting blade 300 on the machine tool holder 600 to accommodate different specifications of pipes.

[0032] like Figure 4 As shown, the adjustment assembly 500 includes a first connector 510, a first rotating shaft 520, a first fixing member 530, a second connector 540, a second rotating shaft 550, a second fixing member 560, and a connecting shaft 570. The first rotating shaft 520 is rotatably connected to the first connector 510, and the first rotating shaft 520 is fixedly connected to the first connector 510 through the first fixing member 530. The second rotating shaft 550 is rotatably connected to the second connector 540, and the second rotating shaft 550 is fixedly connected to the second connector 540 through the second fixing member 560. The two ends of the connecting shaft 570 are respectively connected to the first rotating shaft 520 and the second rotating shaft 550. When adjusting the angle, loosen the first fixing member 530 and the second fixing member 560, rotate the connecting shaft 570, and the connecting shaft 570 drives the first rotating shaft 520 to rotate on the first connecting member 510 and the second rotating shaft 550 to rotate on the second connecting member 540, thereby changing the connection angle between the first connecting member 510 and the second connecting member 540, and thus changing the angle of the cutting mechanism 200 and the chamfering cutting tool 300 on the machine tool holder 600, which facilitates the cutting of pipes of different specifications.

[0033] The adjusting assembly 500 also includes a third fixing member 580. A connecting shaft 570 passes through the first rotating shaft 520 and the second rotating shaft 550, and the connecting shaft 570 is fixedly connected to the first rotating shaft 520 and the second rotating shaft 550 via the third fixing member 580. By allowing the connecting shaft 570 to pass through the first rotating shaft 520 and the second rotating shaft 550, the position of the connecting shaft 570 relative to the first rotating shaft 520 and the second rotating shaft 550 can be changed during adjustment, which facilitates the cutting of pipes of different specifications, and also facilitates the separation of the first connecting member 510 and the second connecting member 540 for maintenance.
