Detailed Implementation

[0018] Example:

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This embodiment provides a composite pipe fitting production equipment, including a frame 1. A hydraulic cylinder 2 is located at the top of the frame, and a worktable 3 is located at the bottom of the frame. A mold connecting plate 6 is connected to the bottom of the hydraulic cylinder, and a sliding plate mold mounting seat 7 is movably connected to the mold mounting seat. A push-in mold 7-1, a diameter-expanding mold 7-2, a port flaring mold 7-3, and a port flanging mold 7-4 are sequentially arranged at the bottom of the sliding plate mold mounting seat. The push-in mold, diameter-expanding mold, port flaring mold, and port flanging mold are all vertically downward. A lower mold 4 is located in the middle of the worktable. The axis of the lower mold 4 is collinear with the axis of the hydraulic cylinder 2. A demolding device 5 is located on one side of the frame 1. The push-in mold, diameter-expanding mold, port flaring mold, and port flanging mold are spaced 10 cm apart. A stepped groove 6-1 is provided at the bottom of the mold connecting plate, and limiting protrusions 7-5 adapted to the stepped groove are provided on both sides of the sliding plate mold mounting seat. The skateboard mold mounting base has four sets of vertical grooves 7-6 on both sides, and the bottom stepped groove of the mold connecting plate has four sets of balls that are compatible with the vertical grooves.

[0020] The working principle and working process of the embodiment in use are as follows:

[0021] Firstly, the pipe base blank 8-2 is placed on the lower mold 4, and then the inner lining stainless steel layer 8-1 is inserted into the pipe base blank 8-2. The push-in mold 7-1 on the slide plate mold mounting seat 7 is pushed into the working position;

[0022] Secondly, the hydraulic cylinder 2 is started, the hydraulic head drives the mold connecting plate 6 to press down, the inner lining stainless steel layer 8-1 is pushed into the pipe base blank 8-2. After reaching the position, the hydraulic cylinder 2 is lifted.

[0023] Thirdly, the diameter expanding mold 7-2 on the slide plate mold mounting seat 7 is pushed into the working position, the hydraulic cylinder 2 is started, the hydraulic head drives the mold connecting plate 6 to press down, the diameter expanding mold 7-2 is pushed into the pipe to be processed 8, the stainless steel is expanded in diameter and closely adheres to the inner wall of the pipe. After reaching the position, the hydraulic cylinder 2 is lifted.

[0024] Fourthly, the port flaring mold 7-3 and the port flanging mold 7-4 on the slide plate 7 are adjusted to the working position in sequence and pressed down, and the whole processing process is completed.
