Description

Technical Field

[0001] This utility model belongs to the field of pipe cutting tooling, and specifically relates to a PVC pipe cutting device. Background Technology

[0002] PVC pipes are plastic pipes made primarily of polyvinyl chloride. They possess advantages such as corrosion resistance, good insulation, and low cost, and are widely used in construction, chemical, and agricultural fields. In practical applications, PVC pipes need to be cut to the required length according to specific usage requirements.

[0003] Common cutting methods include shearing or sawing. Operators measure and mark the required length on the PVC pipe with a tape measure, then use scissors or a saw blade to cut the pipe. However, the misalignment of the scissor blades and the squeezing action during cutting inevitably result in a beveled cut. Saw blades, on the other hand, create burrs on the cut surface. Both shearing and sawing make it difficult to guarantee the quality of the cut, affecting the subsequent assembly and use of the PVC pipe. Furthermore, because operators need to cut large quantities of PVC pipes over extended periods, hand-held cutting is more strenuous and easily leads to fatigue. Additionally, visually determining the cutting position introduces visual errors, causing deviations in the cut length. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a PVC pipe cutting device to solve the problem of poor PVC pipe cutting quality.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a PVC pipe cutting device, comprising: a pushing component, a base with a slide rail on top, and a cutting component with a cutter. The cutting component is fixed on the base at one end of the slide rail. The pushing component includes a slider slidably connected to the slide rail and a stop mechanism installed on one side of the slider. The end of the slider facing the cutter has an installation hole for passing through the PVC pipe. The axis of the installation hole is perpendicular to the cutting edge of the cutter. The stop mechanism limits the cutting length by abutting against the PVC pipe passing through the installation hole. When the slider drives the PVC pipe to slide towards the cutter, the cutter cuts the PVC pipe radially. This technical solution has the following technical effects:

[0006] This invention features a cutting assembly with a blade mounted on a base, along with a pushing assembly slidably connected to the base via a slide rail. This allows the operator to push a slider, moving a PVC pipe through a mounting hole closer to or away from the cutter. As the PVC pipe moves towards the cutter, it is cut. The cutter makes a straight cut from one side of the PVC pipe, reducing effort and avoiding the tearing and burr formation associated with squeeze-type cutting, resulting in a smoother cut. Because the cutting assembly is fixed to the base, the cutter remains stationary. Furthermore, the direction of movement of the PVC pipe is fixed by the sliding rail and slider, ensuring that the axial direction of the PVC pipe through the mounting hole remains perpendicular to the blade. This guarantees that the cutter always cuts the PVC pipe radially, preventing skewing and ensuring cut quality. A single adjustment of the stop mechanism on one side of the slider limits the subsequent cutting length of the PVC pipe, eliminating the need to measure and plan the cutting position on the PVC pipe, thus reducing cutting difficulty.

[0007] In the aforementioned PVC pipe cutting device, the slider includes a pushing part equipped with a stop mechanism, and also includes a sliding part and a positioning part located at both ends of the pushing part. The sliding part is slidably connected to a slide rail. The pushing part has a pushing surface for abutting the PVC pipe, and the positioning part protrudes from the pushing surface. A mounting hole extends through the positioning part along the extension direction of the pushing surface. During cutting, the pushing surface abuts against the PVC pipe, achieving stable pushing of the PVC pipe and preventing the PVC pipe from bending and deforming away from the cutting edge during the cutting process. This ensures stable cutting of the PVC pipe by the cutting edge and thus guarantees cutting accuracy.

[0008] In the aforementioned PVC pipe cutting device, the pushing surface on one side of the positioning part is recessed in the direction away from the cutter to form an arc-shaped surface, so as to fit against the PVC pipe when pushing it close to the cutter. When the pushing part pushes the PVC pipe close to the cutter, the arc-shaped surface can fit against the outer wall of the PVC pipe, thereby increasing the contact area between the PVC pipe and the pushing surface. This makes the pushing part's pushing of the PVC pipe more stable and reliable. During cutting, it also enhances the support of the pushing surface for the PVC pipe, preventing excessive deformation of the PVC pipe.

[0009] In the aforementioned PVC pipe cutting device, the slider is provided with a longitudinally penetrating clearance groove, the opening of which faces the cutter to avoid contact with the PVC pipe cutting blade. This prevents the cutter's edge from colliding with the slider during the later stages of cutting, protecting the cutter, maintaining its sharpness, and extending its service life.

[0010] In the aforementioned PVC pipe cutting device, the blade holder includes a vertically mounted upright and a horizontal crossbar at the top of the upright. The two ends of the cutter are fixed to the crossbar and the upright, respectively, so that the blade is angled downwards. This angled cutter ensures that the PVC pipe is cut from an upward to a downward angle, protecting the operator and significantly reducing the possibility of accidental contact with the blade, thus improving operator safety.

[0011] In the aforementioned PVC pipe cutting device, the cutter is a flat-blade cutter. A flat-blade cutter makes the cut surface of the PVC pipe smoother, improving the cutting quality.

[0012] In the aforementioned PVC pipe cutting device, the stop mechanism includes a support rod and a stop block for abutting the end of the PVC pipe. The stop block is fitted onto the support rod and, by locking it in different positions on the support rod, the cutting length of the PVC pipe can be adjusted. When cutting the PVC pipe, the position of the stop block on the support rod is first adjusted as needed, and then the PVC pipe passing through the mounting hole is abutted against the stop block. The stop block not only limits the cutting length of the PVC pipe but also supports the end of the PVC pipe to ensure the stability of the PVC pipe during cutting.

[0013] In the aforementioned PVC pipe cutting device, a stop block is slidably connected to a support rod. The stop block is equipped with a set screw, which is threaded onto the stop block to fix it at any position on the support rod by abutting against it. The set screw can be rotated to extend into the stop block and abut against or disengage from the support rod. When the set screw abuts against the support rod, the stop block is fixed to the support rod, thus achieving locking of the stop block at any position. The structure is simple and reliable.

[0014] In the aforementioned PVC pipe cutting device, a stop block is threaded onto a support rod, and the stop block moves axially along the support rod by rotation. When it is necessary to adjust the position of the stop block axially on the support rod, rotating the stop block allows it to move axially along the support rod, thus simplifying the stop block structure.

[0015] In the aforementioned PVC pipe cutting device, the pushing assembly further includes a pushing mechanism. This mechanism includes a drive rod with a handle at its top, the bottom of which is rotatably connected to a base. The pushing mechanism also includes transmission rods rotatably connected at both ends to the middle of the drive rod and the top of the slider, respectively. When the drive rod rotates, it drives the slider to slide via the transmission rods. When the operator holds the handle and rotates the drive rod towards the side of the base where the slider is located, the drive rod drives the slider closer to the cutter via the transmission rods. When the operator holds the handle and rotates the drive rod away from the base, the drive rod drives the slider away from the cutter via the transmission rods. The user can achieve slider sliding simply by holding the handle and rotating the drive rod, making operation more labor-saving and avoiding muscle fatigue caused by prolonged batch cutting. Simultaneously, the operator's hands are further away from the blade, preventing cuts and improving operator safety.

[0016] The features and advantages of this utility model will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

[0027] This utility model discloses a PVC pipe cutting device, comprising: a pushing component, a base with a slide rail on top, and a cutting component with a cutter. The cutting component is fixed on the base at one end of the slide rail. The pushing component includes a slider slidably connected to the slide rail and a stop mechanism installed on one side of the slider. The end of the slider facing the cutter has an installation hole for passing through the PVC pipe. The axis of the installation hole is perpendicular to the cutting edge of the cutter. The stop mechanism limits the cutting length by abutting against the PVC pipe passing through the installation hole. When the slider drives the PVC pipe to slide towards the cutter, the cutter cuts the PVC pipe radially. This utility model, by setting the cutting component with the cutter on the base and the pushing component slidably connected to the base via the slide rail, allows the operator to push the slider to move the PVC pipe passing through the installation hole closer to or away from the cutter. When the PVC pipe moves towards the cutter, it can be cut. The cutter makes a straight cut from one side of the PVC pipe, which is more labor-saving and avoids the tearing of the PVC pipe by squeezing cutter, thus avoiding the formation of burrs, resulting in a smoother cut surface. Because the cutting assembly is fixed to the base, the cutter remains stationary. Furthermore, the movement direction of the PVC pipe is constrained by the matching slide rail and slider, ensuring it remains constant. Therefore, as the PVC pipe moves with the slider, the axial direction of the PVC pipe passing through the mounting hole remains perpendicular to the cutter's edge. This allows the cutter to consistently cut the PVC pipe radially, preventing skewing and ensuring cut quality. A single adjustment to the stop mechanism on one side of the slider limits the subsequent cutting length of the PVC pipe, eliminating the need to measure and plan the cutting position on the PVC pipe, thus reducing cutting difficulty.

However, the following embodiments are only preferred embodiments of the present utility model and not all of them.

[0033] Example 1:

[0034] A PVC pipe cutting device, such as Figures 1 to 4 As shown, the assembly includes a base 100, a pushing component, and a cutting component 300. A slide rail 110 is provided on the top of the base 100. The cutting component 300 is fixed on the base 100 and located at one end of the slide rail 110. A cutter 320 for cutting PVC pipe 400 is provided on the cutting component. The pushing component includes a slider 210 and a stop mechanism 220. The slider 210 is slidably connected to the slide rail 110. The stop mechanism 220 is installed on the side of the slider 210 so as to move in conjunction with the slider 210 when the slider 210 slides along the slide rail 110. A mounting hole 2131 is provided at the end of the slider 210 facing the cutter 320. The axial direction of the mounting hole 2131 is perpendicular to the blade 321 of the cutter 320.

[0035] When cutting PVC pipe 400, the stop mechanism 220 can be adjusted according to the required length of PVC pipe 400. That is, the distance between the position of the stop mechanism 220 that abuts against the end of PVC pipe 400 and the cutter 320 is adjusted to the required length of PVC pipe 400 to limit the cutting length of PVC pipe 400. Then, the PVC pipe 400 to be cut is inserted into the mounting hole 2131 until the end of PVC pipe 400 abuts against the stop mechanism 220. Next, the slider 210 is pushed to slide along the slide rail 110 toward the cutting assembly 300. 210 drives the PVC pipe 400 to slide towards the cutter 320 through the mounting hole 2131. During the sliding process, the cutter 320 cuts the PVC pipe 400 radially. After the cutting is completed, the slider 210 is slid away from the cutter 320 and then pushed towards the stop mechanism 220 until the PVC pipe 400 passing through the mounting hole 2131 abuts against the stop mechanism 220. Then the slider 210 can be pushed towards the cutting assembly 300 again to perform the next cut of the PVC pipe 400.

[0036] This invention provides a cutting assembly 300 with a cutter 320 on a base 100 and a pushing assembly slidably connected to the base 100 via a slide rail 110. This allows the operator to push the slider 210 to move the PVC pipe 400, which passes through the mounting hole 2131, closer to or away from the cutter 320. When the PVC pipe 400 moves toward the cutter 320, it can be cut. The cutter 320 makes a straight cut from one side of the PVC pipe 400, which is more labor-saving and avoids tearing the PVC pipe 400 by squeezing or tearing it by multiple cuts, or forming burrs by multiple cuts. The cut surface is smoother. Because the cutting assembly 300 is fixed on the base 100, the cutter 320 remains stationary on the base 100. Furthermore, the direction of movement of the PVC pipe 400 is fixed by the cooperating slide rail 110 and slider 210. Therefore, as the PVC pipe 400 moves with the slider 210, the axial direction of the PVC pipe 400 passing through the mounting hole 2131 remains perpendicular to the blade 321 of the cutter 320. This ensures that when cutting the PVC pipe 400, the cutter 320 can always cut the PVC pipe 400 radially, preventing skewing and ensuring cut quality. A single adjustment of the stop mechanism 220 on one side of the slider 210 limits the subsequent cutting length of the PVC pipe 400. Precise cutting of the PVC pipe 400 can be achieved without measuring and planning the cutting position on the PVC pipe 400, reducing the difficulty of cutting.

[0037] In this embodiment, the slider 210 includes a sliding part 211, a pushing part 212, and a positioning part 213. The sliding part 211 is located at the end of the pushing part 212 away from the cutter 320 and passes through the groove 111 of the slide rail 110 to slide in connection with the slide rail 110. The positioning part 213 is located at the end of the pushing part 212 facing the cutter 320. The stop mechanism 220 is installed on one side of the pushing part 212. The pushing part 212 has a pushing surface 2121. A positioning part 213 is provided at the end of the pushing part 212 facing the cutter 320 to abut against the PVC pipe 400. A mounting hole 2131 protrudes from the pushing surface 2121 and extends through the positioning part 213 along the extending direction of the pushing surface 2121. When the end of the PVC pipe 400 passes through the mounting hole 2131 and abuts against the stop mechanism 220, the outer side wall of the portion of the PVC pipe 400 between the stop mechanism 220 and the positioning part 213 abuts against the pushing surface 2121. The cutter 320 is opposite to the pushing surface 2121, as shown below. Figure 1 As shown, during cutting, the cutter 320 cuts the PVC pipe 400 along the side of the positioning part 213 toward the stop mechanism 220. The pushing surface 2121 can abut against the PVC pipe 400 to achieve stable pushing of the PVC pipe 400, avoiding bending and deformation of the PVC pipe 400 away from the cutter 320 during the cutting process, ensuring stable cutting of the PVC pipe 400 by the cutter 320, and thus ensuring cutting accuracy. Preferably, the pushing surface 2121 is located between the positioning part 213 and the stop mechanism 220. The pushing surface 2121 is recessed in the direction away from the cutter 320 to form an arc-shaped surface. When the pushing part 212 pushes the PVC pipe 400 close to the cutter 320, the arc-shaped surface can fit against the outer wall of the PVC pipe 400 to increase the contact area between the PVC pipe 400 and the pushing surface 2121, making the pushing part 212 push the PVC pipe 400 more stable and reliable. During cutting, it can also enhance the support of the pushing surface 2121 on the PVC pipe 400 and prevent the PVC pipe 400 from being excessively deformed.

[0038] The sliding part 211, the pushing part 212, and the positioning part 213 can be an integral structure or separate parts. In this embodiment, the sliding part 211 and the pushing part 212 are integrally formed, and the positioning part 213 and the pushing part 212 are detachably connected to each other to facilitate the installation and removal of the positioning part 213. When it is necessary to cut PVC pipes 400 of different diameters, the positioning part 213 with the hole diameter of the mounting hole 2131 that matches the PVC pipe 400 can be replaced to prevent the PVC pipe 400 from shaking on the positioning part 213. When the mounting part is damaged, the mounting part can also be replaced separately to reduce maintenance and replacement costs.

[0039] In this embodiment, the slider 210 is provided with a clearance groove 214, which extends longitudinally through the slider 210. The opening of the clearance groove 214 faces the cutter 320. When the slider 210 pushes the PVC pipe 400 closer to the cutter 320 so that the cutter 320 cuts the PVC pipe 400, such as... Figure 2 As shown, the clearance groove 214 can avoid the cutter 320, preventing the blade 321 of the cutter 320 from colliding with the slider 210 in the later stage of cutting, thus protecting the cutter 320, maintaining the sharpness of the blade 321, and extending the service life of the cutter 320.

[0040] like Figure 4 As shown, in this embodiment, the blade holder 310 includes a vertically arranged upright 311 and a horizontally arranged crossbar 312 at the top of the upright 311. The upright 311 and the crossbar 312 are integrally formed. The two ends of the cutter 320 are respectively fixed to the crossbar 312 and the upright 311, so that the blade 321 of the cutter 320 is inclined downward. The slider 210 pushes the PVC pipe 400 below the crossbar 312, so that the cutter 320 can cut the PVC pipe 400. The inclined cutter 320 cuts the PVC pipe 400 from an upward angle to an downward angle, and can protect the operator during use, greatly reducing the possibility of the operator accidentally touching the blade 321 and improving the operator's safety. Preferably, the cutter 320 is a flat-blade cutter, which can make the cut surface of the PVC pipe 400 smoother and improve the cutting quality.

[0041] In this embodiment, the stop mechanism 220 includes a horizontally extending support rod 221 and a stop block 222 sleeved on the support rod 221. The extension direction of the support rod 221 is parallel to the axial direction of the mounting hole 2131. The stop block 222 can slide along the axial direction of the support rod 221 and be locked at different positions on the support rod 221. The distance between the stop block 222 and the cutter 320 is the cutting length of the PVC pipe 400. That is, the cutting length of the PVC pipe 400 can be adjusted by moving the stop block 222 on the support rod 221. When the PVC pipe 400 needs to be cut, the position of the stop block 222 on the support rod 221 is first adjusted as needed. Then, the PVC pipe 400 passing through the mounting hole 2131 is abutted against the stop block 222. The stop block 222 can not only limit the cutting length of the PVC pipe 400, but also support the end of the PVC pipe 400 to ensure that the PVC pipe 400 remains stable during cutting.

[0042] In this embodiment, the stop block 222 is slidably connected to the support rod 221. A set screw 2221 is provided on the stop block 222, threadedly connected to it. The set screw 2221 can be rotated to extend into the stop block 222 and abut against or disengage from the support rod 221. When the set screw 2221 abuts against the support rod 221, the stop block 222 is fixed to the support rod 221, thus achieving locking of the stop block 222 at any position. The structure is simple and reliable. Preferably, to further improve the adjustment speed of the stop block 222, a scale can be marked on the support rod 221, allowing the operator to slide and adjust the stop block 222 according to the scale.

[0043] In this embodiment, the pushing assembly further includes a pushing mechanism 230, which includes a drive rod 231 and a transmission rod 232. The top of the drive rod 231 has a handle 2311, and the bottom of the drive rod 231 is rotatably connected to the base 100. One end of the transmission rod 232 is rotatably connected to the middle of the drive rod 231, and the other end of the transmission rod 232 is rotatably connected to the slider 210. When the operator holds the handle 2311 and rotates the drive rod 231 toward the side of the base 100 where the slider 210 is located, the drive rod 231 drives the slider 210 via the transmission rod 232. As block 210 moves closer to cutter 320, when the operator holds handle 2311 and rotates drive rod 231 away from base 100, drive rod 231 drives block 210 away from cutter 320 via transmission rod 232. The user can slide block 210 by holding handle 2311 and rotating drive rod 231, which makes operation more labor-saving and avoids muscle fatigue caused by long-term batch cutting. At the same time, the operator's hand holding handle 2311 is farther away from the blade 321, avoiding cuts and improving operator safety.

[0044] Example 2:

[0045] The difference between this embodiment and Embodiment 1 is that in this embodiment, the stop block is sleeved on the support rod and has an internal thread inside. The support rod has an external thread, and the stop block and the support rod are connected by the mating internal and external threads. When it is necessary to adjust the position of the stop block in the axial direction of the support rod, the stop block can be rotated to move the stop block along the axial direction of the support rod, thus simplifying the stop block structure.

[0046] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
