Specific embodiments

[0022] In order to more clearly understand the above purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the drawings and examples. It should be explained that the examples and features in the examples of the present application can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth in order to fully understand the utility model, but the utility model can also be implemented in other ways different from the description, therefore, the utility model is not limited to the specific examples disclosed in the following description.

[0024] Example one: refer to Figures 1-5 As shown: a kind of rolling pipe end forming machine, including operation platform 3, operation platform 3 top is slidably connected with rolling mechanism 2, and rolling mechanism 2 side is provided with cooling mechanism, and cooling mechanism includes cooling cylinder 8, fan 12 and water tank 14, and fan 12 bottom is fixedly connected with guide plate 11, and guide plate 11 top is provided with mounting hole, and guide plate 11 bottom is slidably connected with operation platform 3, and guide plate 11 one end is fixedly connected with water tank 14, and water tank 14 side is engagedly connected with operation platform 3, and one side of water tank 14 is fixedly connected with collection hopper 15, and collection hopper 15 top is fixedly communicated with cooling cylinder 8, and cooling cylinder 8 inner ring surface is fixedly connected with annular spray pipe 16, and one side of annular spray pipe 16 is fixedly communicated with spray head, and the outer ring surface of annular spray pipe 16 is fixedly communicated with connecting pipe one 17, and one end of connecting pipe one 17 is fixedly communicated with the water outlet of water pump 18, and the water inlet of water pump 18 is fixedly communicated with connecting pipe two 19, and one end of connecting pipe two 19 is fixedly communicated with water tank 14, and water tank 14 top is fixedly connected with water pump 18.

[0025] The through-hole on one side of the cooling cylinder 8 facilitates the insertion of the pipe into the cooling cylinder 8. The water pump 18 accelerates the flow of water from the water tank 14 into the annular spray pipe 16, thereby achieving water cooling of the pipe. The collection hopper 15 guides the flow of wastewater inside the cooling cylinder 8, facilitating the recycling of wastewater in the water tank 14. The guide plate 11 connects the water tank 14 and the fan 12, thereby changing the position of the fan 12 and the water tank 14 as the guide plate 11 slides along the top of the operating table 3. When the cooling cylinder 8 separates from the left end of the pipe, the fan 12 moves from the right end of the pipe to the middle area of ​​the pipe, which can accelerate the airflow speed at different positions of the pipe, thereby improving the cooling effect on the pipe. At the same time, the top of the guide plate 11 has a mounting hole, which can be fixed by installing bolts between the mounting hole and the operating table 3 after the position of the guide plate 11 is adjusted, ensuring the stable use of the guide plate 11, the water tank 14 and the fan 12.

[0026] Example 2: Figures 1-4 As shown, a mold frame 1 is fixedly connected to the top of the operating table 3. A detection frame 20 is fixedly connected to one side of the mold frame 1. A laser rangefinder sensor is fixedly connected to one side of the detection frame 20. A pressing mold 7 is installed on one side of the mold frame 1. A hydraulic cylinder 6 is embedded in one side of the mold frame 1. A side plate 13 is fixedly connected to one end of the hydraulic cylinder 6. A support platform 5 is attached to the top of the side plate 13. A clamping assembly 4 is fixedly connected to the top of the support platform 5. An electric push rod 9 is fixedly connected to the bottom of the support platform 5. A fixing plate 10 is fixedly connected to the bottom of the electric push rod 9. One side of the fixing plate 10 is fixedly connected to the side plate 13, and one side of the support platform 5 is slidably connected to the mold frame 1.

[0027] The mold frame 1 allows adjustment of the height of the upper pressing mold 7, thereby controlling the closing or separation of the two pressing molds 7. Based on the changes in detection data from the laser rangefinder on one side of the detection frame 20, it can be determined whether the pipe has reached the designated position, reducing positional deviation during pipe processing. The mold frame 1 provides support for the installation and use of the hydraulic cylinder 6. The hydraulic cylinder 6 allows adjustment of the distance between the side plate 13 and the mold frame 1, facilitating changes in the distance between the support platform 5 and the clamping assembly 4 and the mold frame 1. After the clamping assembly 4 clamps the pipe, the pipe can be moved and adjusted. The fixing plate 10 reinforces the bottom support of the electric push rod 9. The electric push rod 9 allows adjustment of the height of the support platform 5 and the clamping assembly 4, facilitating quick separation of the pipe from the pressing mold 7 at the bottom after processing.

[0028] The working principle and method of using the device are as follows: first, the pipe is placed in the pressing die 7 below, then the pipe is clamped by the clamping assembly 4, the clamping assembly 4 is a pneumatic finger, the side plate 13 and the support table 5 are driven by the hydraulic cylinder 6 to move to the side close to the die frame 1, so that the right end of the pipe is close to the rolling mechanism 2, the position of the pipe is detected by the laser ranging sensor on one side of the detection frame 20, when the pipe is located on one side of the sensor, the distance measured by the sensor changes, which can assist in judging that the pipe reaches the specified position, at this time, the hydraulic equipment in the die frame 1 drives the pressing die 7 above to move downward, and the pipe is pressed, then the two rolling mechanisms 2 are used to roll the pipe, after rolling, the fan 12 cools one end of the pipe, the water pump 18 pumps out the water in the water tank 14, and sends it into the annular spray pipe 16 through the connecting pipe 17, so as to spray the other end of the pipe, thereby accelerating the cooling of the pipe, after cooling, the guide plate 11 is moved on the top of the operation table 3, so that the left end of the pipe is separated from the cooling cylinder 8, the bolt is used to fix the moved guide plate 11, then the hydraulic equipment drives the pressing die 7 above to separate from the pipe, at this time, the electric push rod 9 drives the support table 5 and the clamping assembly 4 to move upward, so that the pipe can be separated from the pressing die 7 below, then the pipe clamped by the clamping assembly 4 can be taken out.

[0029] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification of the above embodiments without departing from the technical scheme of the present application, according to the technical essence of the present application, still belongs to the protection scope of the present application.
