[0025] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0026] Embodiment 1, as Figures 1-5As shown in the figure, the present utility model provides a polyurethane insulation pipe punching and foaming integrated device, including: a support frame 4, a sliding groove 18 is provided at the top of the support frame 4, the front surface of the support frame 4 is fixedly connected with a first motor 16, the output end of the first motor 16 movably penetrates through the front surface of the support frame 4 and extends into the sliding groove 18, the output end of the first motor 16 is fixedly connected with a lead screw 15, the outer surface of the lead screw 15 is connected with a sliding seat 12, a first electric telescopic rod 13 is fixedly connected to the top of the sliding seat 12 near the rear side, a second electric telescopic rod 19 is fixedly connected to the top of the sliding seat 12 near the front side, the driving ends of the first electric telescopic rod 13 and the second electric telescopic rod 19 both movably penetrate through the top of the sliding seat 12, the driving end of the first electric telescopic rod 13 is fixedly connected with a second motor 23, the output end of the second motor 23 is fixedly connected with a drill bit 22, the driving end of the second electric telescopic rod 19 is fixedly connected with an injection head 20, an injection pipe 21 is fixedly connected to the front surface of the injection head 20, the rear end surface of the lead screw 15 is rotatably connected to one inner wall of the sliding groove 18, a guide rod 17 is fixedly connected to the inner surface of the sliding groove 18, the outer surface of the guide rod 17 movably penetrates through the inner surface of the sliding seat 12, the bottom of the support frame 4 is fixedly connected with a base 1, two support plates 3 are symmetrically fixedly connected to the top of the base 1, two second electric push rods 5 are symmetrically fixedly connected to the top of the support frame 4, the driving ends of the two second electric push rods 5 both movably penetrate through the top of the support frame 4, the driving ends of the two second electric push rods 5 are both fixedly connected with upper clamping blocks 6, two lower clamping blocks 7 are symmetrically fixedly connected to the top of the base 1, the positions of the two lower clamping blocks 7 respectively cooperate with the positions of the two upper clamping blocks 6, rubber pads 11 are fixedly connected to the inner surfaces of the two lower clamping blocks 7 and the two upper clamping blocks 6, and the positions of the two lower clamping blocks 7 respectively cooperate with the position of a sealing ring 9.

[0027] The effect achieved by the entire Example 1 is that when perforating and foaming a polyurethane insulation pipe, the polyurethane insulation pipe is placed on two lower clamping blocks 7, and then two second electric push rods 5 are started, and their driving ends move downward, thereby driving two upper clamping blocks 6 to move downward. Therefore, when the two lower clamping blocks 7 and the two upper clamping blocks 6 are used in cooperation, the polyurethane insulation pipe is clamped and fixed, and under the action of a plurality of rubber pads 11, the fixing effect on the polyurethane insulation pipe can be improved, ensuring the stability of the insulation pipe during the perforating and foaming processes. When the polyurethane insulation pipe is fixed, by starting the first motor 16, the lead screw 15 is driven to rotate, and under the action of the guide rod 17, the sliding seat 12 moves linearly along the lead screw 15 and the guide rod 17, thereby driving the drill bit 22 to move above the polyurethane insulation pipe. Then, the first electric telescopic rod 13 is started to drive the drill bit 22 to move downward. At the same time, the second motor 23 is started to rotate the drill bit 22 to perform the perforating work on the polyurethane insulation pipe. After the perforating is completed, the drill bit 22 is reset, and then the first motor 16 is started to adjust the position of the sliding seat 12, and the injection head 20 is moved above the perforating position. Then, the second electric telescopic rod 19 is started to insert the injection head 20 into the hole, and the injection pipe 21 is connected to an external foaming machine, so that the foaming agent is injected into the polyurethane insulation pipe through the start of the external foaming machine to perform the foaming work, thereby realizing the integration of perforating and foaming, improving the production efficiency of the polyurethane insulation pipe, and at the same time reducing the complexity and labor intensity of manual operation.

[0028] Example 2, as Figures 1-5 shown, on one outer surface of each of the two support plates 3, a first electric push rod 2 is fixedly connected. The driving ends of the two first electric push rods 2 respectively penetrate through the outer surfaces of the two support plates 3. The driving ends of the two first electric push rods 2 are both fixedly connected with a connecting rod 8. On the outer surface of each of the two connecting rods 8, a sealing ring 9 is fixedly connected. A sealing groove 10 is opened at one end of each of the two sealing rings 9.

[0029] The effect achieved by the entire Example 2 is that before drilling, two first electric push rods 2 can be started to drive the two connecting rods 8 to move, so that the two sealing rings 9 seal and clamp the two ends of the polyurethane insulation pipe, and the sealing groove 10 cooperates with the outer pipe of the polyurethane insulation pipe to further enhance the sealing effect, enabling the foaming agent to uniformly expand inside the pipe and form a uniform foam structure.

[0030] Working principle: When perforating and foaming a polyurethane insulation pipe, place the polyurethane insulation pipe on two lower clamping blocks 7, and then start two second electric push rods 5 to make their driving ends move downward, thereby driving two upper clamping blocks 6 to move downward. Therefore, when the two lower clamping blocks 7 and the two upper clamping blocks 6 are used in cooperation, the polyurethane insulation pipe is clamped and fixed. Under the action of multiple rubber pads 11, the fixing effect of the polyurethane insulation pipe can be improved, ensuring the stability of the insulation pipe during the perforating and foaming process. After the polyurethane insulation pipe is fixed, start two first electric push rods 2 to drive two connecting rods 8 to move, so that two sealing rings 9 seal the two ends of the polyurethane insulation pipe. Start the first motor 16 to drive the lead screw 15 to rotate, and under the action of the guide rod 17, the sliding seat 12 moves linearly along the lead screw 15 and the guide rod 17, thereby driving the drill bit 22 to move above the polyurethane insulation pipe. Then start the first electric telescopic rod 13 to drive the drill bit 22 to move downward. At the same time, start the second motor 23 to make the drill bit 22 rotate to perforate the polyurethane insulation pipe. After the perforating is completed, reset the drill bit 22, and then start the first motor 16 to adjust the position of the sliding seat 12 to move the injection head 20 above the perforating position. Then start the second electric telescopic rod 19 to insert the injection head 20 into the hole, and the injection pipe 21 is connected to an external foaming machine. Thus, by starting the external foaming machine, foaming agent is injected into the polyurethane insulation pipe for foaming. By blocking both ends of the pipe, the foaming agent can expand uniformly inside the pipe to form a uniform foam structure, thereby realizing the integration of perforating and foaming, improving the production efficiency of the polyurethane insulation pipe, and at the same time reducing the complexity and labor intensity of manual operation.

[0031] The wiring diagrams of the first electric push rod 2, the second electric push rod 5, the first electric telescopic rod 13, the second electric telescopic rod 19, the first motor 16 and the second motor 23 in the present utility model belong to the common knowledge in the art. Their working principles are already known technologies, and their models are selected according to actual use. Therefore, the control methods and wiring arrangements of the first electric push rod 2, the second electric push rod 5, the first electric telescopic rod 13, the second electric telescopic rod 19, the first motor 16 and the second motor 23 will not be explained in detail.
