Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, and in particular to a cutting device for the production of composite insulation pipes. Background Technology

[0002] The main function of composite insulated pipes is to achieve efficient insulation, energy saving, and safety protection by optimizing the pipe structure. Composite insulated pipes use high-efficiency insulation materials such as polyurethane, reducing heat loss to 25%-30% of traditional pipes, resulting in significant energy cost savings over long-term use. Some models (such as PERT II) further optimize insulation performance through patented foaming technology, achieving high temperature resistance up to 180℃. The outer high-density polyethylene protective layer and seamless rubber ring sealing design effectively prevent pipe leakage and corrosion, making them particularly suitable for underground direct burial or humid environments.

[0003] The aforementioned existing technical solutions have the following drawbacks: due to their unique layered structure, it is not easy to control the dimensions during cutting, and a certain amount of redundancy is required to facilitate on-site removal and adjustment, which leads to a great waste of time. It is necessary to trim the dimensions to the correct position during the initial cutting to avoid the need for secondary processing on the installation site. Utility Model Content

[0004] The purpose of this invention is to provide a cutting device for the production of composite insulation pipes, so as to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A cutting device for producing composite insulation pipes includes a working platform. A bidirectional drive module is fixedly installed on the top left side of the working platform. Holding blocks are provided at both ends of the bidirectional drive module. The bidirectional drive module is used to drive the holding blocks to move closer to each other. A linear drive module is provided on the top of the working platform. A shearing device is provided on the linear drive module. The linear drive module is used to drive the shearing device to move left and right. A displacement sensor is provided on the linear drive module. The displacement sensor is used to detect the moving distance of the shearing device.

[0007] By adopting the above technical solution, the shearing force of the shearing device can be controlled to clamp or shear the pipe. The combination of displacement sensor and shearing device can achieve high-precision cutting of the pipe at a fixed distance. The bidirectional drive module can clamp pipes of different diameters, making the device more widely applicable.

[0008] In a further embodiment, the bidirectional drive module includes a fixed frame, a double-ended screw, a drive motor, and guide rods. Two guide rods are symmetrically fixed to the top of the fixed frame. The drive motor is fixedly mounted at the top of the fixed frame. The double-ended screw is rotatably mounted on the top of the fixed frame, positioned between the two guide rods. The axes of the double-ended screw and the two guide rods are both in the front-back direction. Threaded sleeves are symmetrically threaded onto the double-ended screw. Protrusions are provided on both sides of the threaded sleeves, and each protrusion has a through-hole that mates with the two guide rods. The output shaft of the drive motor is connected to the rear end of the double-ended screw, and the drive motor drives the double-ended screw to rotate axially. Two clamping blocks are fixedly mounted on the top of the threaded sleeves. The sides of the two clamping blocks that are close to each other have mating grooves for clamping pipes passing between them.

[0009] In a further embodiment, rollers are provided on both the left and right sides of the top of the fixing frame.

[0010] By adopting the above technical solution, when the drive motor drives the double-ended screw to rotate, the threaded sleeve is restricted by the guide rod and cannot generate a following axial rotation. Therefore, the two threaded sleeves on the double-ended screw will move closer or further away from each other when the double-ended screw rotates axially, so that they are synchronized when clamping the pipe passing through the middle, ensuring that pipes of different diameters are centered and clamped.

[0011] In a further embodiment, the linear drive device is a linear drive motor, and the shearing device is a pipe cutter.

[0012] In a further embodiment, the displacement sensor is an infrared ranging grating, and the bottom of the shearing device is provided with a reflection recognition area corresponding to the displacement sensor.

[0013] By adopting the above technical solution, the displacement sensor and the reflection recognition area work together to determine the displacement distance of the shearing device. When shearing the pipe, the shearing device first clamps the pipe, then moves it to the right by a specified distance to cut off the end face of the pipe, removing waste material and making the end face of the pipe flat. Then the clamping block clamps the left end of the pipe, the shearing device releases the right end of the pipe and moves to the left end of the pipe to shear it. This process is repeated to obtain a pipe with high precision and flat end faces.

[0014] In a further embodiment, a material drop plate is provided on the top right side of the work platform.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. By controlling the shearing force of the shearing device, the pipe can be clamped or sheared. With the cooperation of the displacement sensor and the shearing device, the pipe can be cut at a fixed distance with high precision. The bidirectional drive module can clamp pipes of different diameters, making the device more widely applicable. Attached Figure Description
