Detailed Implementation
[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0019] Combined with appendix Figures 1 to 4 As shown, this embodiment discloses an automatic flaring and baking device for 3PE pipes, including a frame 1, an automatic gripping robot 2, a baking mechanism 3, and a flaring mechanism 4. The automatic gripping robot 2, the baking mechanism 3, and the flaring mechanism 4 are mounted on the frame 1. The baking mechanism 3 includes a heating coil lifting mechanism and an electric heating coil 35. The electric heating coil 35 is mounted on the heating coil lifting mechanism. A fixing fixture 36 is mounted below the electric heating coil 35 and is fixed to the frame 1. The fixing fixture 36 is used to fix the steel-plastic conversion pipe.
[0020] The heating coil lifting mechanism includes a servo motor 31, a lead screw 32, a lifting guide rail 33, and a lifting seat 34. The servo motor 31 is fixed on the frame 1 and connected to the lead screw 32. The lead screw 32 is screwed to a nut on the lifting seat 34. The lifting guide rail 33 is mounted on the frame 1, and the lifting seat 34 is mounted on the lifting guide rail 33. An electric heating coil 35 is mounted on the lifting seat 34 and is fitted over the outside of the steel-plastic conversion tube. When the servo motor 31 operates, it drives the lead screw 32 to rotate, which in turn drives the lifting seat 34 and the electric heating coil 35 fixed thereon to rise and fall together.
[0021] A flaring mechanism 4 is provided on one side of the fixed fixture 36. The flaring mechanism 4 includes a flaring tripod 41, three hydraulic cylinders 42, and three flaring claws 43. The flaring tripod 41 is fixed on a fixed base 44, which is fixed on the frame 1. Each of the three ends of the flaring tripod 41 is provided with a hydraulic cylinder 42, which is connected to the flaring claws 43. The flaring tripod 41 has three sliding grooves. The lower part of the flaring claws 43 is located in the sliding grooves of the flaring tripod 41. When the hydraulic cylinders 42 are working, they can drive the flaring claws 43 to move along the flaring tripod 41. The flaring mechanism 4 uses a high-precision hydraulic diverter valve to evenly and stably distribute the oil from the hydraulic station to the three hydraulic cylinders, so as to realize the slow and synchronous movement of the hydraulic cylinders and to realize the flaring of the plastic shrink sleeve in three directions. A fixed stroke is achieved by inputting a fixed amount of hydraulic oil to ensure a fixed flaring distance.
[0022] The automatic gripping robot 2 is fixed on a robot arm mounting frame 24, which is fixed to the upper part of the frame 1. The automatic gripping robot 2 includes a three-axis moving mechanism 21, a rotating mechanism 22, and a pneumatic gripper 23. The pneumatic gripper 23 is mounted on the rotating mechanism 22, which is mounted on the three-axis moving mechanism 21. The three-axis moving mechanism 21 includes an X-axis moving mechanism, a Y-axis moving mechanism, and a Z-axis moving mechanism. The X-axis moving mechanism is mounted on the robot arm mounting frame 24, the Y-axis moving mechanism is mounted on the X-axis moving mechanism, the Z-axis moving mechanism is mounted on the Y-axis moving mechanism, and the rotating mechanism 22 is mounted on the Z-axis moving mechanism. The rotating mechanism 22 includes a rotating motor and a rotating mounting plate. The rotating motor is mounted on the Z-axis moving mechanism and connected to the rotating mounting plate. The pneumatic gripper 23 is fixed on the rotating mounting plate.
[0023] The frame 1 is equipped with four baking mechanisms 3, which can simultaneously bake and heat four plastic shrink sleeves.
[0024] Working process: The equipment is turned on in pneumatic mode. The worker first places four steel-plastic conversion pipes on the corresponding fixed fixtures, and then places the plastic shrink sleeve to be flared on the flaring mechanism 4. After the flaring mechanism reaches the flaring position, it holds pressure for a period of time to allow the material to fully deform. The upper robotic arm moves to the appropriate position and uses the pneumatic gripper 23 to grip the plastic shrink sleeve. After gripping, the flaring cylinder retracts, and the robotic arm transports the plastic shrink sleeve to the designated 3PE steel-plastic conversion steel pipe. Then, the servo motor 31 works, and the electric heating coil 35 starts to move up and down under the drive of the servo motor 31 to heat and bake the plastic shrink sleeve. After baking for a certain period of time, the plastic shrink sleeve is initially and firmly fixed on the 3PE steel-plastic conversion steel pipe. Then, the pneumatic gripper 23 on the robotic arm is released and moves back to the standby point to start the next work cycle.
[0025] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
