DETAILED DESCRIPTION

[0013] The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. The embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0014] The embodiment of the present invention provides a hand-held turning mechanism for turning outer round chips for a steel skeleton reinforced polyethylene composite pipe, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a turning part, an outer wall fixing mechanism, a handheld handle 5, a handheld fixing frame 6, and a tube inner wall clamping mechanism.

[0015] like Figure 1 and Figure 2 As shown, the turning part mainly uses a turning tool 2 to turn the outer wall of the composite pipe. The turning part includes a motor 1 and a turning tool 2. The motor 1 is located on one side of the outer cylindrical material turning mechanism and is connected to a handheld fixing frame 6. The turning tool 2 is installed at the end of the output shaft of the motor 1. The rotation of the motor 1 drives the turning tool 2 to rotate, and by selecting different turning tools 2, the outer wall of the composite pipe can be turned into specified different shapes. The motor 1 has a precise speed control function, and its speed can be adjusted within a certain range. The turning tool 2 adopts a high-precision manufacturing process, and the blade is sharp and wear-resistant.

[0016] like Figure 1 and Figure 2 As shown, the outer wall fixing mechanism includes an outer wall fixing rod 3 and an outer wall bearing 4. The outer wall fixing rod 3 is U-shaped. Both ends of the outer wall fixing rod 3 extend from the inner side of the handheld fixing frame 6 close to the motor 1. The extension length can be adjusted according to the size of the turning tool 2 to determine the turning depth of the turning tool 2 on the outer wall of the composite pipe. The outer wall fixing rod 3 is made of high-strength alloy material, and the adjustment method is accurate and reliable. The outer wall bearing 4 is installed on the outer wall fixing rod 3. The outer wall bearing 4 can ensure that the handheld turning outer round chip mechanism rotates along the radial direction of the composite pipe. The outer wall bearing 4 is a high-precision, high-load-bearing capacity rolling bearing with good lubrication and an outer ring that is wear-resistant and corrosion-resistant.

[0017] like Figure 1 and Figure 2 As shown, the handheld handle 5 is rotated radially along the composite pipe by gripping it, providing power to the device in the radial direction. The handheld handle 5 is ergonomically designed, has a non-slip surface, and a solid internal structure. The motor 1 control button and speed knob are provided at appropriate positions on the handle.

[0018] like Figure 1 and Figure 2 As shown, the handheld fixing frame 6 is U-shaped to ensure that the turning position and the turning size are close to the end face of the composite pipe. The handheld fixing frame 6 is made of high-strength aluminum alloy or stainless steel. The U-shaped groove size matches the outer diameter of the common composite pipe and the inner wall has a buffer material. The two side arms are provided with precise scale markings.

[0019] like Figure 1 and Figure 2 As shown, the inner wall clamping mechanism of the pipe includes a cylinder 7, an inner wall fixed bearing 8, and an inner wall fixed rod 9. The cylinder 7 is installed on one side of the handheld fixing frame 6, and the inner wall fixed rod 9 is located inside the handheld fixing frame 6, and its two ends are respectively connected to the piston rods of the two cylinders 7. The cylinder 7 extends to push the inner wall fixed rod 9 to the inner wall of the pipe to ensure that the inner wall fixed bearing 8 fits the inner wall of the composite pipe. The composite pipe is clamped by clamping the wall thickness of the composite pipe through the outer wall fixing mechanism and the inner wall clamping mechanism of the pipe, and then turning is performed. The cylinder 7 has a fast response speed, a stable movement, a large thrust, and a stroke that can be selected according to the wall thickness of the composite pipe. The control method is diverse. The cylinder 7 is equipped with a safety protection device, including an overload protection valve and a buffer device to prevent accidents from causing damage to the cylinder 7 and the composite pipe. The inner wall fixed bearing 8 is similar to the outer wall bearing 4 and has an adjustable size. The inner wall fixed rod 9 is made of high-strength steel with good straightness and rigidity. It is provided with a guide device and the length is adjustable and equipped with a locking device.

[0020] In one embodiment, a certain gap is maintained between the housing of the motor 1 and surrounding components to facilitate heat dissipation and prevent the accumulation of heat generated by long-term operation from affecting the performance of the motor 1. After the power cord is led out from the housing of the motor 1, it is routed along the handheld fixing bracket 6 or other suitable paths and finally connected to the power supply device. The wiring method should ensure that the power cord does not interfere with the normal operation of the device and is not damaged by chips during the turning process.

[0021] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, the steps of using a hand-held turning mechanism for cutting outer round chips for a steel skeleton reinforced polyethylene composite pipe are provided: Step 1: Check the equipment before operation. Carefully check whether the motor 1 is damaged, check the blade of the turning tool 2, the blade should be sharp without gaps and evenly worn, check the firmness of the handheld handle 5, etc.; Step 2, install the equipment on the composite pipe. First, open the U-shaped groove of the handheld fixing bracket 6 toward the composite pipe. Slowly move the equipment, put the U-shaped groove on the composite pipe, adjust the position of the equipment, so that the top surface of the handheld fixing bracket 6 is flush with the end surface of the composite pipe; then start the cylinder 7 of the pipe inner wall clamping mechanism, slowly increase the pressure of the cylinder 7 by controlling the valve, extend the piston rod, push the inner wall fixing rod 9 to drive the inner wall fixing bearing 8 to move toward the inner wall of the pipe, and when the composite pipe can be stably fixed and the composite pipe does not undergo obvious displacement or shaking during the rotation of the equipment, stop increasing the pressure and the installation is complete; Step 3, debugging of turning part. Select a suitable turning tool 2 and install it on the tool holder, make sure that the turning tool 2 is firmly installed, and the angle between the cutting edge and the outer wall of the composite tube is correct, then start the motor 1, observe whether the rotation direction of the turning tool 2 is correct, and whether the running state is stable. If the state is inconsistent with the normal state, stop the machine and readjust the position and angle of the turning tool 2 until it meets the start-up requirements; Step 4, turning operation. The operator holds the handheld handle 5 with both hands and stands in a position convenient for operation and observation. Start the motor 1, and after the turning tool 2 rotates stably, slowly apply thrust along the radial direction of the composite pipe to make the equipment start to move in a circle around the outer wall of the composite pipe. At the beginning of turning, the thrust should be small and uniform, so that the turning tool 2 gradually cuts into the outer wall of the composite pipe to avoid damage to the turning tool 2 or gnawing of the composite pipe surface due to sudden excessive force; Step 5: When the outer wall of the composite pipe reaches the predetermined size, shape and surface quality requirements, stop the operation of the motor 1, retract the piston rod of the cylinder 7, and carefully remove the hand-held outer cylindrical chip turning mechanism from the composite pipe.

[0022] The present invention has a number of significant beneficial effects: the handheld fixing frame is designed to be U-shaped and embraces the outer circumference of the composite pipe. This design enables the equipment to fit the composite pipe tightly, ensuring the stability and processing accuracy of the composite pipe during the turning process; the pipe inner wall clamping mechanism includes two cylinders, an inner wall fixed bearing and an inner wall fixed rod. The cylinder pushes the inner wall fixed rod to clamp the inner wall, preventing displacement during the turning process and ensuring the accuracy of the processing; the cylinder is equipped with an overload protection valve and a buffer device, which improves the safety and reliability of the equipment.
