Description

Technical Field

[0001] This utility model relates to a switching device, and in particular to a pipe cutting device. Background Technology

[0002] The molding of PVC pipes follows the basic principles of thermal processing. Dry PVC plastic particles are heated and melted using specialized extrusion equipment to form a melt with good fluidity. This melt is then shaped through a mold and continuously extruded using a traction device, finally cooling to form pipe products of different specifications. These pipes are widely used in water supply and drainage, HVAC, and electrical wiring due to their advantages such as corrosion resistance, high strength, and easy installation.

[0003] In practical engineering applications, PVC pipes supplied in rolls or fixed lengths need to be precisely cut according to the on-site installation dimensions to meet assembly requirements such as pipeline routing and connection nodes. Currently, the industry's conventional PVC pipe cutting mostly uses circular saw cutting devices. Its core working mechanism is to drive the cutting disc to rotate at high speed through a drive motor, while simultaneously using a lifting mechanism to control the vertical displacement of the cutting disc, thereby achieving the cutting operation of the fixed pipe.

[0004] While this cutting method is characterized by its ease of operation and high cutting efficiency, it places specific requirements on the working space, especially the clearance height above the cutting device. This is because after the cutting disc completes a cut, it needs to be raised to its initial position via a lifting mechanism to remove the cut pipe and clamp new material. During this process, the cutting device needs to operate to its upper limit position. If the clearance above is insufficient, key components of the cutting device, such as the lifting mechanism and motor assembly, are prone to collisions and interference with the overhead structure or other equipment.

[0005] Such interference may not only cause mechanical damage to the cutting device and affect the service life of the equipment, but also lead to deviations in cutting positioning accuracy, resulting in quality problems such as tilted pipe cuts and inaccurate dimensions. In severe cases, it may also cause safety hazards such as equipment jamming and sudden stop.

[0006] In summary, reducing the space occupied by the cutting device's stroke has become an urgent problem for researchers in this field. Utility Model Content

[0007] The technical problem to be solved by this utility model is: how to reduce the space occupied by the stroke of the cutting device; To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: This utility model is a pipe cutting device, including: a worktable, a clamping component for fixing the pipe is provided on the worktable, a cutting component for cutting the pipe is provided above the clamping component, and a guide opening for the pipe to be discharged after cutting is provided on the worktable on one side of the clamping component. The cutting assembly includes: a fixed base, which is fixed to the worktable; a tilting base is hinged to the fixed base; a spindle sleeve is provided at the end of the tilting base and above the clamping assembly; a cutting disc is provided on one side of the spindle sleeve; the rotational power of the motor is transmitted from the other side of the spindle sleeve; the axis of the cutting disc is parallel to the axis of the pipe; and a telescopic cylinder is provided between the worktable and the tilting base to control the cutting disc to move closer to or away from the pipe.

[0008] Furthermore, the bottom surface of the flipping seat is provided with a support lug, one end of the telescopic cylinder is hinged to the worktable, and the other end of the telescopic cylinder is hinged to the support lug.

[0009] Furthermore, a protective cover is fixed to the cutting disc.

[0010] Furthermore, limit plates are provided on both sides of the material guide opening and on the worktable.

[0011] Furthermore, the clamping assembly includes: a slide fixed on the workbench, two slide plates on the slide plate, and a roller shaft for supporting the pipe rotatably mounted on the slide plate, the axis of the roller shaft being parallel to the axis of the pipe; A clamping cylinder is installed directly above the pipe. The clamping cylinder is fixed by a mounting bracket. The output end of the clamping cylinder is set downward and is equipped with an electric roller. When the electric roller contacts the pipe supported on the roller shaft, it drives the pipe to rotate.

[0012] Furthermore, the clamping assembly includes: a support base provided on one side of the slide block, a bidirectional lead screw passing through the support base and connected to the two slide plates, and a drive handwheel provided at the end of the bidirectional lead screw; rotating the drive handwheel moves the two roller shafts closer or further apart.

[0013] The beneficial effects of this utility model are as follows: This utility model is a pipe cutting device that achieves pipe cutting by flipping the rotating seat. Compared with the traditional up-and-down cutting method, the stroke of the cutting disc is vertical. This embodiment is simpler in terms of arrangement.

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] Figure 1 This is a structural schematic diagram of this embodiment; Figure 2 This is a side view of this embodiment; Figure 3 This is a schematic diagram of the cutting components; Figure 4 This is a schematic diagram of the clamping assembly. Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0017] See Figure 1-2 This embodiment is a pipe cutting device, including: a workbench 1, a clamping component 2 for fixing the pipe is provided on the left side of the workbench, a cutting component 3 for cutting the pipe is provided above the clamping component 2, and a guide opening 4 for the pipe to be discharged after cutting is provided on the right side of the workbench 1. The pipe enters horizontally from the left side of the clamping assembly 2, and the pipe is clamped onto the clamping assembly 2. The cutting assembly 3 then cuts the pipe. The cut pipe is then discharged from the guide opening 4. The pipe is then pushed to the right, and the pipe is placed back in the position to be cut. The cutting of the pipe is repeated.

[0018] See Figure 3 The cutting assembly 3 includes: a fixed base 31, which is fixed on the worktable 1. A flipping base 32 is hinged to the fixed base 31. A spindle sleeve 33 is provided at the end of the flipping base 32 and above the clamping assembly 2. A cutting disc 34 is provided on one side of the spindle sleeve 33. The rotational power of the motor 35 is transmitted from the other side of the spindle sleeve 33. The axis of the cutting disc 34 is parallel to the axis of the pipe. A telescopic cylinder 36 is provided between the worktable 1 and the flipping base 32 to control the cutting disc 34 to move closer to or away from the pipe.

[0019] After the pipe is fixed on the clamping assembly 2, the telescopic cylinder 36 is extended. At this time, the flipping seat 32 rotates from the horizontal state to the tilted state. The cutting disc 34, which is in the lower position, cuts the pipe. The power of the cutting disc is transmitted to the right side of the main shaft sleeve 33 by the motor 35 through the belt, driving the cutting disc 34 on the left side of the main shaft sleeve 33 to rotate.

[0020] In this embodiment, the pipe is cut by flipping the rotating seat 32. Compared with the traditional up-and-down cutting method, the stroke of the cutting disc is vertical. This embodiment is simpler in terms of arrangement. In terms of the stroke space of the cutting component 3, the stroke trajectory of the cutting disc 34 in this embodiment is roughly arc-shaped, thus reducing the space occupied by the stroke of the cutting device 3.

[0021] See Figure 2In some possible embodiments, the bottom surface of the flipping seat 32 is provided with a support lug 37, one end of the telescopic cylinder 36 is hinged to the worktable 1, and the other end of the telescopic cylinder 36 is hinged to the support lug 37. In this embodiment, the two ends of the telescopic cylinder 36 are hinged to the lugs 37 of the flip seat 32 and to the worktable 1, respectively. Thus, by extending or retracting the telescopic cylinder 36, the flip seat 32 can be switched from a horizontal to an inclined state.

[0022] See Figure 3 In some possible embodiments, a protective cover 38 is fixed at the cutting disc 34; In this embodiment, a protective cover 38 is provided to prevent the waste generated by the cutting disc 34 during cutting from splashing.

[0023] See Figure 4 In some possible embodiments, the clamping assembly 2 includes: a slide 21 fixed on the workbench 1, two slide plates 22 on the slide 21, and a roller shaft 23 rotatably mounted on the slide plate 22 to support the pipe, the axis of the roller shaft 23 being parallel to the axis of the pipe; a clamping cylinder 24 is disposed directly above the pipe, the clamping cylinder 24 is fixed by a mounting bracket 25, the output end of the clamping cylinder 24 is disposed downward, and an electric roller 26 is mounted thereon, which drives the pipe to rotate when the electric roller 26 contacts the pipe supported on the roller shaft 23; In this embodiment, the pipe is supported between two roller shafts 23. A clamping cylinder 24 is provided above the two roller shafts 23. The electric roller 26 at the output end of the clamping cylinder 24 can move downward to clamp the pipe between the roller shafts 23 and position the pipe axially between the two roller shafts 23. At this time, the electric roller 26 rotates and drives the pipe to rotate during cutting through friction. In this way, the position of the cutting disc 34 does not change during cutting, thus realizing the slitting of the pipe.

[0024] See Figure 4 In some possible embodiments, a support seat 27 is provided on one side of the slide 21, a bidirectional lead screw 28 passes through the support seat 27 and is connected to the two slide plates 22, and a drive handwheel 29 is provided at the end of the bidirectional lead screw 28. Rotating the drive handwheel 29 can bring the two roller shafts 23 closer or further apart. In this embodiment, the two roller shafts 23 can be moved closer or further apart by rotating the drive handwheel 29 to meet the cutting needs of pipes of different diameters.
