Description

Technical Field

[0001] The utility model relates to the field of pipe cutting, in particular to a cutting tool for pipe processing. Background Art

[0002] Pipe fittings are a general term for parts and components that play the role of connection, control, direction change, diversion, sealing, and support in pipeline systems. According to different processing technologies, they are divided into four categories, namely welded pipe fittings, seamless pipe fittings, socket welded and threaded pipe fittings, and flanged pipe fittings.

[0003] The cutting disc of the existing cutting tool for pipe processing usually cuts the pipe from top to bottom along the vertical direction when cutting the pipe, which is suitable for cutting straight pipes.

[0004] With respect to the above-mentioned related technologies, when the existing pipe cutting tool cuts the elbow of the pipe, the cutting disc moves from top to bottom toward the part of the pipe that needs to be cut. Since there are two straight pipes close to each other at the elbow of the pipe, the cutting disc is likely to cut the other straight pipe that does not need to be cut when moving downward, or it is difficult to cut the required part during the cutting process. In addition, the clamps in the existing cutting tool can often only fix the pipe at a single angle, so that the cutting tool cannot cut the elbow of the pipe at a specific cutting angle. Therefore, the existing cutting tool for pipe processing is not easy to cut the elbow of the pipe at a specific angle. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a cutting tool for pipe processing, so as to solve the technical problem that the existing cutting tool for pipe processing is not easy to cut the pipe elbow at a specific angle.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cutting tool for pipe processing, comprising a workbench, a first slide is slidably arranged on the bottom surface of the workbench along the length direction, a bearing platform is rotatably connected to the bottom end of the first slide, a second slide is slidably arranged on the surface of the bearing platform along the length direction, a cutting disc for cutting pipe fittings is installed on the second slide, and clamps for clamping pipe fittings are arranged at intervals along the length direction on one side of the workbench close to the bearing platform.

[0007] By adopting the above technical solution, the cutting equipment slidably connected to the supporting platform is used to cut the elbow of the pipe fixed on the workbench, so that the elbow of the pipe can be cut at a specific angle in the horizontal direction without affecting another straight pipe at the elbow of the pipe.

[0008] The utility model is further configured that a screw is rotatably arranged in the middle of the bottom surface of the workbench along the length direction, one end of the screw is connected to the output end of the first motor through a transmission belt, and the screw passes through the first slide.

[0009] By adopting the above technical solution, the first motor cooperates with the transmission belt to drive the screw to rotate, thereby driving the first slide to slide on the bottom surface of the workbench.

[0010] The utility model is further configured such that a guide ring is fixedly connected to the side wall of the first slide, the guide ring is in an arc shape and the center of the circle coincides with the axis of the bearing platform shaft, and the guide ring passes through the bearing platform.

[0011] By adopting the above technical solution, the supporting platform can be stably rotated and the stability of the supporting platform after rotation is effectively improved.

[0012] The utility model is further configured that a positioning knob is arranged on the top surface of the bearing platform in the direction of the guide ring, and a scale showing the rotation angle of the bearing platform is printed on the guide ring.

[0013] By adopting the above technical solution, the supporting platform can be prevented from rotating during the cutting process by tightening the positioning knob.

[0014] The utility model is further configured such that a dislocation groove for displacing the positioning knob is provided in the middle of the second slide.

[0015] By adopting the above technical solution, the sliding of the second slide table is not affected by the positioning knob.

[0016] The utility model is further configured such that a fixed plate is fixedly connected to the second slide platform, a lifting plate is connected to the fixed plate for sliding up and down, a mounting plate is fixedly connected to the top of the lifting plate, a second motor is mounted on the mounting plate, a cutting disc is connected to the output end of the second motor, and a projection of the cutting disc toward the ground does not overlap with the supporting platform.

[0017] By adopting the above technical solution, the position of the cutting disc can be adjusted in the vertical direction.

[0018] The utility model is further configured such that a plurality of telescopic columns in a vertical state are connected between the mounting plate and the fixed plate, a spring in a compressed state is arranged inside the telescopic column, and a handle is fixedly connected to the mounting plate on a side away from the cutting disc.

[0019] By adopting the above technical solution, the cutting disc can be easily pushed and the height of the cutting disc can be adjusted by holding the handle.

[0020] In summary, the utility model mainly has the following beneficial effects:

[0021] 1. The utility model sets a sliding track on the bottom surface of the workbench, sets a rotatable bearing platform on the sliding track, and uses the cutting equipment slidably connected to the bearing platform to cut the elbow of the pipe fixed on the workbench. Since the bearing platform can rotate to adjust the angle and slide in the track of the workbench to adjust the position, it can achieve cutting of the elbow of the pipe at a specific angle in the horizontal direction without affecting another straight pipe at the elbow of the pipe;

[0022] 2. The utility model sets a cutting device that can be raised and lowered by sliding on a bearing platform, and the height of the cutting device can be manually controlled during cutting. Since the center heights of pipes with different diameters are different, the height of the cutting device can be adjusted to ensure that the elbows of the pipes are fully cut, avoiding the situation where the pipes cannot be cut.
