Description

Technical Field

[0001] This application relates to the field of pipe fitting processing technology, and in particular to a cutting mechanism for pipe fittings. Background Technology

[0002] Currently, pipe cutting machines are specialized equipment used for the precise cutting of various pipe materials (such as PVC, metal, and composite pipes). They encompass types such as manual cutters, electric abrasive saws, CNC pipe cutting machines, and laser cutting machines, and are suitable for industries such as construction, automotive, and medical. Their core functions include fixed-length cutting, multi-angle cutting, and burr control. When selecting a machine, it is necessary to match the pipe material (soft / hard), precision requirements (standard / high precision), and budget (manual tools are cheaper, CNC / laser equipment is more expensive) to ensure efficient, burr-free, or easily processed cut quality.

[0003] In the existing technology, when cutting a PVC pipe, the PVC pipe is fixed and then a blade is used to cut the pipe.

[0004] Regarding the aforementioned technologies, the inventors believe that during the cutting of pipe fittings, the PVC material is squeezed due to plastic deformation, forming rolled burrs. These burrs need to be removed subsequently, which affects the cutting efficiency of the pipe fittings. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a cutting mechanism for pipe fittings, which solves the technical problem that when pipe fittings are cut, the PVC material is squeezed due to plastic deformation, forming rolled burrs, and the burrs need to be removed later, which affects the cutting efficiency of pipe fittings.

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

[0007] A pipe fitting cutting mechanism includes a cutting machine body, wherein a clamping jaw is provided on the cutting machine body and is rotatably mounted on the cutting machine body for clamping the pipe fitting, characterized in that: a sliding frame is provided on the cutting machine body, a cutter and a grinding head are provided on the sliding frame, and the cutter and the grinding head are arranged opposite to each other; a first adjusting component is provided on the cutting machine body for adjusting the position of the cutter; and a second adjusting component is provided on the cutting machine body for adjusting the position of the grinding head.

[0008] Furthermore, the first adjustment component includes a first adjustment frame, which is mounted on the sliding frame. A pressure block is provided on the first adjustment frame, and the pressure block is locked onto the first adjustment frame. A pressure groove is formed on the pressure block, and the cutter is installed in the pressure groove.

[0009] Furthermore, a guide slope is formed on the cutter, the guide slope is oriented away from the first adjusting frame, and the guide slope is used to guide the cut debris.

[0010] Furthermore, a first adjusting cylinder is provided on the sliding frame. The first adjusting cylinder is horizontally mounted on the sliding frame, and one end of the piston rod of the first adjusting cylinder is connected to the first adjusting frame.

[0011] Furthermore, the second adjustment assembly includes a second adjustment frame, the grinding head is mounted on the second adjustment frame, and the sliding frame is provided with an adjustment motor and an adjustment screw. One end of the adjustment screw is connected to the adjustment motor, and the other end is threadedly connected to the second adjustment frame.

[0012] Furthermore, a second adjusting cylinder is provided on the second adjusting frame, the second adjusting cylinder is horizontally installed on the second adjusting frame, and the grinding head is embedded in one end of the piston rod of the second adjusting cylinder.

[0013] Furthermore, the cutting machine body is provided with a sliding motor and a sliding screw. The sliding motor is mounted on the cutting machine body, one end of the sliding screw is connected to the sliding motor, the other end passes through the sliding frame, and the sliding screw is threadedly connected to the sliding frame.

[0014] In summary, this application includes at least one of the following beneficial technical effects of a pipe cutting mechanism:

[0015] 1. When in use, install the pipe fitting on the cutting machine body. The gripper clamps one end of the pipe fitting and drives the pipe fitting to rotate on the cutting machine body. Then, the first adjustment component and the second adjustment component drive the cutter and the grinding head to move closer to the pipe fitting. The cutter cuts the pipe fitting and the grinding head removes the burrs on the pipe fitting, thereby reducing the curled burrs formed at the end of the pipe fitting during cutting and improving the cutting efficiency of the pipe fitting.

[0016] 2. By using the guide bevel on the cutter and adjusting the cylinder, the generation of burrs at the pipe end can be reduced, and the generation of burrs on the pipe can be reduced.

[0017] 3. The adjustment motor, adjustment screw, and second adjustment cylinder on the sliding frame improve the ease of pressing the grinding head against the pipe fitting. Attached Figure Description

[0024] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0026] This application discloses a cutting mechanism for pipe fittings.

[0027] Reference Figure 1 , Figures 4-5 A pipe cutting mechanism includes a cutting machine body 1, on which a clamping jaw 11 is rotatably mounted. In use, the clamping jaw 11 clamps one end of the pipe fitting, which then rotates on the cutting machine body 1. A sliding frame 2 is provided on the cutting machine body 1, and a cutting blade 21 and a grinding head 22 are mounted on the sliding frame 2, with the cutting blade 21 and grinding head 22 arranged opposite to each other. A first adjusting component 3 and a second adjusting component 4 are provided on the cutting machine body 1, which drive the cutting blade 21 and the grinding head 22 to move closer to or further away from each other.

[0028] Reference Figure 2The sliding frame 2 is slidably mounted on the cutting machine body 1. Further, the cutting machine body 1 is equipped with a sliding motor 12 and a sliding screw 13. The sliding motor 12 is mounted on the cutting machine body 1, and the axis of the sliding screw 13 is parallel to the axis of the pipe fitting. One end of the sliding screw 13 is connected to the sliding motor 12, and the other end passes through the sliding frame 2, with the sliding screw 13 threadedly connected to the sliding frame 2. In use, the sliding motor 12 drives the sliding screw 13 to rotate. As the sliding screw 13 rotates, the sliding frame 2 slides along the axis of the pipe fitting on the cutting machine body 1. This allows the cutter 21 to cut the pipe fitting into several segments.

[0029] Reference Figure 3 The first adjusting assembly 3 includes a first adjusting frame 31, on which a pressure block 32 is provided. A pressure groove 33 is formed on the side of the pressure block 32 near the first adjusting frame 31. The cutter 21 is installed in the pressure groove 33 of the first adjusting frame 31. In use, the pressure block 32 is locked onto the first adjusting frame 31, pressing the cutter 21 against the first adjusting frame 31. When the cutter 21 wears down during pipe cutting, the pressure block 32 is removed from the first adjusting frame 31, and the cutter 21 is replaced, thus improving the ease of cutter 21 replacement.

[0030] Reference Figure 4 Furthermore, a guide slope 211 is formed on one side of the cutter 21, and the inclined direction of the guide slope 211 is towards the side away from the first adjusting frame 31. When the cutter 21 cuts the pipe, the guide slope 211 guides the cutting debris of the pipe, improves the cutting efficiency of the pipe, and reduces the burrs generated during the cutting process.

[0031] In addition, a first adjusting cylinder 34 is provided on the first adjusting frame 31. The first adjusting cylinder 34 is horizontally mounted on the sliding frame 2, and one end of the piston rod of the first adjusting cylinder 34 is connected to the first adjusting frame 31. In use, the first adjusting cylinder 34 drives the cutter 21 to move closer to or further away from the pipe. As the pipe rotates, the cutter 21 slowly moves closer to the pipe, allowing the pipe to be cut.

[0032] The second adjusting assembly 4 includes a second adjusting frame 41, which is slidably mounted on a sliding frame 2. An adjusting motor 42 and an adjusting screw 43 are mounted on the sliding frame 2. One end of the adjusting screw 43 is connected to the adjusting motor 42, and the other end passes through the second adjusting frame 41, with the screw 43 threadedly connected to the second adjusting frame 41. In use, as the adjusting motor 42 rotates, the adjusting screw 43 rotates on the sliding frame, causing the second adjusting frame 41 to move closer to or further away from the pipe fitting. In operation, the first adjusting frame 31 and the second adjusting frame 41 move towards or away from each other on the sliding frame 2.

[0033] Reference Figure 5 A second adjusting cylinder 44 is mounted on the second adjusting frame 41, with one end of the piston rod of the second adjusting cylinder 44 facing towards the side closer to the pipe. Furthermore, the grinding head 22 is spherical in shape and is embedded in one end of the piston rod of the second adjusting cylinder 44, with the grinding head 22 rotatably connected to the piston rod of the second adjusting cylinder 44. In use, the adjusting motor 42 drives the adjusting screw 43 to rotate, and the rotation of the adjusting screw 43 moves the second adjusting frame 41 towards the side closer to the pipe. When the cutter 21 presses against the pipe, the grinding head 22 simultaneously presses against the pipe, and as the cutter 21 cuts the pipe, the grinding head 22 removes the burrs from one end of the pipe.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
