Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to a pipe cutting device. Background Technology

[0002] A pipe cutting device is a piece of equipment used for precise cutting of metal pipes or fittings. This device uses a special cutting tool and a power system to quickly and accurately cut pipes to set dimensions and angles.

[0003] Chinese Patent Application No. CN202421073476.3 discloses a cutting device for processing drainage pipes, which includes an operating table, a cutting component set on the operating table, and two sets of fixing mechanisms set on the operating table. The upper surface of the operating table is provided with a placement groove for placing pipes. The cutting component includes a first slider, a cylinder, a blade for cutting the pipe, and a drive motor. The two sets of fixing mechanisms are respectively set on both sides of the cutting component. The fixing mechanism includes a mounting bracket, a clamping block, and a screw that drives the clamping block to move. The mounting bracket is set on the upper surface of the operating table and is located on the side of the placement groove near the first slider. The clamping block is set directly above the placement groove and is slidably connected to the bracket. The screw is threadedly connected to the mounting bracket and is rotatably connected to the clamping block through one end of the mounting bracket.

[0004] The above-mentioned technical solution can achieve rapid clamping of pipes of any length. However, in practical applications, the device can only cut the cut surface of the pipe into a flat plane. If it is necessary to process the cut surface into a bevel, the device cannot meet this requirement, thus reducing the applicability and practicality of the device. Utility Model Content

[0005] The main purpose of this utility model is to provide a pipe cutting device that can cut the pipe surface into a flat surface or a bevel, thereby improving the applicability and practicality of the device.

[0006] To achieve the above objectives, this utility model proposes a pipe cutting device, including an operating table, a cutting device disposed on the top of the operating table, and a pusher for moving the cutting device. Both sides of the operating table are provided with placement plates, and each placement plate is provided with a placement groove for placing pipes. One side of the two placement plates is fixedly connected by a V-block, and the V-block is rotatably connected to the top of the operating table through a rotating shaft. The operating table is also provided with a locking assembly for fixing the placement plates.

[0007] In one possible implementation, arc-shaped limiting plates are fixedly connected to both sides of the operating platform. The arc-shaped limiting plates have arc-shaped grooves inside, and the center of the arc-shaped grooves coincides with the center of the rotating shaft. Each of the placement plates has a sliding plate fixedly connected to the side of the arc-shaped limiting plate, and each sliding plate is slidably connected to the inner wall of the corresponding arc-shaped groove.

[0008] In one possible implementation, the locking assembly includes an opening slot at the top of the arc-shaped groove and a fixing bolt. The opening slot is arc-shaped, and the center of the opening slot coincides with the center of the rotating shaft. The diameter of the fixing bolt is smaller than the width of the opening slot. The fixing bolt is disposed inside the opening slot and is threadedly connected to the slide plate on one side. The bolt head of the fixing bolt abuts against the top of the arc-shaped limiting plate.

[0009] In one possible implementation, a washer is provided between the bolt head of the fixing bolt and the arc-shaped limiting plate.

[0010] In one possible implementation, each of the placement plates is provided with a fixing assembly for fixing the pipe fittings on its top. The fixing assembly includes a gantry frame disposed on the top of the placement plate, a fixing block slidably connected to the inside of the gantry frame, and an adjusting screw. The fixing block has a fixing groove on the side near the placement groove. The adjusting screw is disposed on the top of the fixing groove and rotatably connected to the fixing groove. One side of the adjusting screw passes through the gantry frame and extends to its outside. The adjusting screw is threadedly connected to the gantry frame. A knob is fixedly connected to the side of the adjusting screw away from the gantry frame.

[0011] In one possible implementation, the cross-sections of both the fixing groove and the placement groove are V-shaped.

[0012] In one possible implementation, guide rods are fixedly connected to both sides inside the gantry frame, and the two sides of the fixing block are slidably connected to the corresponding guide rods.

[0013] This invention achieves rotatable placement plate relative to the operating table by incorporating a V-block and a rotating shaft. When cutting pipe fittings with inclined end faces, the placement plate can rotate around the shaft to adjust the placement angle of the pipe fitting. For example, to cut a pipe fitting with a 45° bevel, the placement plate can be rotated to a suitable angle, at which point the axis of the pipe fitting forms a 45° angle with the original perpendicular cutting direction of the cutting device. The cutting device can then process the cut surface of the pipe fitting into a bevel. For cutting a flat surface, the placement plate can be placed horizontally, and then the cutting device can perform the cutting. This allows the device to process the cut surface of the pipe fitting into a flat surface while also meeting the processing requirements for various inclined angle cuts, thereby improving the applicability and practicality of the device.

[0014] The locking mechanism can be used to fix the placement plate after the angle is adjusted, preventing the placement plate from rotating during the cutting process, thereby ensuring the stability and accuracy of the cutting process. Attached Figure Description

[0022] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0024] refer to Figure 1-5This embodiment proposes a pipe cutting device, including an operating table 1, a cutting device disposed on the top of the operating table 1, and a pusher 101 for moving the cutting device. The cutting device typically includes a cutting plate 4, a cutting blade 401 rotatably connected to the cutting plate 4, and a motor 402 for driving the cutting blade 401 to rotate. The top of the operating table 1 should be provided with a clearance groove to allow space for the cutting blade 401 to cut the pipe. The pusher 101 can be an electric push rod, a hydraulic cylinder, or any mechanism that can move the cutting blade 401 and cut the pipe; this embodiment does not impose excessive limitations on this.

[0025] Furthermore, both sides of the operating table 1 are provided with placement plates 102, and there is a cutting space between the two placement plates 102. The clearance groove should be set in the cutting space. Each placement plate 102 is provided with a placement groove 103 for placing pipe fittings. One side of the two placement plates 102 is fixedly connected by a V-block 104, and the V-block 104 is rotatably connected to the top of the operating table 1 through a rotating shaft 105. The operating table 1 is also provided with a locking assembly for fixing the placement plates 102.

[0026] When the operator needs to process the cut surface of the pipe fitting into an inclined surface, the placement groove 103 can be rotated around the rotating shaft 105 to a specified angle, and then the placement plate 102 can be fixed using the locking assembly to prevent it from rotating. Next, the pipe fitting to be cut is placed in the placement groove 103, and the operator can use their hands or other tools to fix the pipe fitting. Subsequently, the cutting device is started, causing the cutting blade 401 to rotate, and the pusher 101 is activated to push the cutting device to cut the pipe fitting. Through this process, the device can process the cut surface of the pipe fitting into a flat surface and also meet the processing requirements of various inclined angle cut surfaces, thereby improving the applicability and practicality of the device.

[0027] Furthermore, in this embodiment, arc-shaped limiting plates 2 are fixedly connected to both sides of the operating table 1. Arc-shaped limiting plates 2 are provided with arc-shaped grooves 201 inside. The center of the arc-shaped grooves 201 coincides with the center of the rotating shaft 105. Each placement plate 102 is fixedly connected to a sliding plate 202 on the side near the arc-shaped limiting plate 2. Each sliding plate 202 is slidably connected to the inner wall of the corresponding arc-shaped groove 201.

[0028] The purpose of aligning the center of the arc groove 201 with the center of the rotating shaft 105 is to enable the slide plate 202 to slide within the arc groove 201 when the placement plate 102 rotates around the rotating shaft 105, thereby limiting the rotation of the placement plate 102, reducing the possibility of deviation during rotation, and ensuring the accuracy of the pipe cutting angle.

[0029] Specifically, the locking assembly includes an opening groove 203 at the top of the arc-shaped groove 201 and a fixing bolt 204. The opening groove 203 is arc-shaped, and the center of the opening groove 203 coincides with the center of the rotating shaft 105. The diameter of the fixing bolt 204 is smaller than the width of the opening groove 203. The fixing bolt 204 is located inside the opening groove 203 and is threaded to the slide plate 202 on one side. The bolt head of the fixing bolt 204 abuts against the top of the arc-shaped limiting plate 2.

[0030] After the operator adjusts the angle of the placement plate 102, the fixing bolt 204 can be inserted into the opening slot 203 and connected to the threaded connection of the slide plate 202. Then, the operator can use a tool to tighten the fixing bolt 204 until the bolt head contacts the top of the arc-shaped limiting plate 2. Using the principle of friction, the slide plate 202 is fixed within the arc-shaped groove 201, thus ensuring the stability of the placement plate 102. Through this friction-based fixing method, the slide plate 202 can be held in any position within the arc-shaped groove 201, meeting the processing requirements of various inclined angle cutting surfaces, thereby improving the applicability of the device.

[0031] Furthermore, the width of the opening slot 203 is designed to be greater than the bolt diameter. This is to allow operators to adjust the angle of the placement plate 102 without removing the entire fixing bolt 204 from the sliding plate 202. They only need to detach the bolt head from the surface of the arc-shaped limiting plate 2, and then the sliding plate 202 can move the fixing bolt 204 within the opening slot 203. This design not only reduces the risk of losing the fixing bolt 204 but also improves the ease of operation.

[0032] Meanwhile, to ensure the stability of the placement plate 102, a washer 205 is placed between the bolt head of the fixing bolt 204 and the arc-shaped limiting plate 2. When the fixing bolt 204 is tightened, the washer 205 increases the contact area between the bolt head and the arc-shaped limiting plate 2, making the fixing bolt 204 less likely to loosen after tightening, and further enhancing the fixing effect on the placement plate 102.

[0033] In this embodiment, a fixing assembly for fixing pipe fittings is also provided on the top of each placement plate 102. The fixing assembly includes a gantry 3 set on the top of the placement plate 102, a fixing block 301 slidably connected to the inside of the gantry 3, and an adjusting screw 302. The fixing block 301 has a fixing groove 303 on the side near the placement groove 103. The adjusting screw 302 is set on the top of the fixing groove 303 and is rotatably connected to the fixing groove 303. One side of the adjusting screw 302 passes through the gantry 3 and extends to its outside. The adjusting screw 302 is threadedly connected to the gantry 3. A knob 304 is fixedly connected to the side of the adjusting screw 302 away from the gantry 3.

[0034] When processing pipe fittings, the fittings are passed horizontally through each gantry 3, and the portion to be cut is placed between two placement plates 102. Then, the operator rotates knob 304, which drives adjusting screw 302 to rotate. Adjusting screw 302 moves fixing block 301 downwards, and fixing groove 303 on fixing block 301 secures the fitting within placement groove 103, preventing displacement and ensuring the fittings do not shift due to cutting force during the cutting process, thus guaranteeing cutting accuracy. Simultaneously, by adjusting screw 302, the fixing requirements of fittings with different diameters can be accommodated, improving the versatility of the fixing components and enhancing the overall cutting device's ability to process fittings of different specifications.

[0035] Meanwhile, to improve the fixing effect of the fixing components, the cross-sections of the fixing groove 303 and the placement groove 103 are both designed as "V" shapes. The "V" shape can better fit the outer surface of the pipe fitting, and compared with the planar structure, it has a larger contact area and a better fixing effect. Several anti-slip textures can also be provided on the outer surfaces of the fixing groove 303 and the placement groove 103 to further increase the contact area between them, thereby improving the fixing effect.

[0036] Furthermore, guide rods 305 are fixedly connected to both sides inside the gantry frame 3, and the two sides of the fixing block 301 are slidably connected to the corresponding guide rods 305. When the adjusting screw 302 is rotated to move the fixing block 301 up and down, the guide rods 305 play a guiding role, ensuring that the fixing block 301 can only move up and down along the direction of the guide rods 305, preventing the fixing block 301 from shifting or shaking during movement. This ensures that it can apply vertical downward pressure to the pipe fitting, improving the fixing effect.

[0037] Working principle:

[0038] When the operator needs to machine the cut surface of the pipe fitting into an inclined surface, the placement groove 103 can be rotated around the pivot 105 to a specified angle. After the operator adjusts the angle of the placement plate 102, the fixing bolt 204 can be inserted into the opening groove 203 and made to connect with the threaded connection of the sliding plate 202. Subsequently, the operator can use a tool to tighten the fixing bolt 204 so that the bolt head contacts the top of the arc-shaped limiting plate 2, and uses the principle of friction to fix the sliding plate 202 in the arc-shaped groove 201, thereby ensuring the stability of the placement plate 102.

[0039] Next, the pipe is passed horizontally through each gantry 3, and the part to be cut is placed between two placement plates 102. Then, the operator turns the knob 304, which drives the adjusting screw 302 to rotate. The adjusting screw 302 moves the fixing block 301 downward, and the fixing groove 303 on the fixing block 301 fixes the pipe in the placement groove 103 to prevent the pipe from shifting. Then, the cutting device is started, the cutting blade 401 is rotated, and the pusher 101 is started to push the cutting device to cut the pipe.

[0040] After processing, rotate knob 304 in the opposite direction to detach the reinforcing block from the surface of the pipe, and then remove the cut pipe.
