Description

Technical Field

[0001] This utility model relates to the field of pipe expansion technology, specifically a pipe end expansion device. Background Technology

[0002] Pipe end expanders are key equipment used in the processing of plastic pipes. They are mainly used to process thin pipes into thicker ones and are commonly found in drainage pipes, water supply and drainage systems, cable protection pipes, and other scenarios. With the increasing requirements of modern engineering for the corrosion resistance, ease of installation, and service life of pipeline systems, technological innovation in pipe expanders has become particularly important.

[0003] Traditional pipe end expansion devices require manual loading and expansion of the pipe ends. Traditional devices require manual placement of individual pipes at the expansion point for expansion, followed by pipe replacement after expansion. This prolonged work not only increases labor intensity but is also quite cumbersome. Therefore, we propose a new pipe end expansion device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pipe end expansion device, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipe end expansion device, comprising an operating plate, two fixed plates fixedly installed on the top of the operating plate, two connecting plates fixedly installed on one side of one of the fixed plates, a second hydraulic cylinder fixedly installed inside each of the two connecting plates, a movable support block fixedly installed at the output end of each of the two second hydraulic cylinders, a limit rod fixedly connected to the side of each of the two support blocks that is far apart from each other, and the two limit rods are slidably connected to the two connecting plates respectively, an electric push rod fixedly installed on the top of the operating plate, a support plate fixedly installed at the output end of the electric push rod, two second support legs fixedly installed on the top of the operating plate, and a [missing information - likely a device or component] fixedly installed at the top of each of the two second support legs. The mounting plates have two first support legs fixedly mounted at their bottom ends. Two conveyor rollers are rotatably connected between the two mounting plates. A motor is fixedly mounted on one side of one of the mounting plates. One end of one of the conveyor rollers passes through one of the mounting plates and is fixedly connected to the output end of the motor. Two conveyor belts are drivenly connected to the surfaces of the two conveyor rollers. Several protrusions are fixedly mounted on the surfaces of the two conveyor belts. Before expanding the pipe, the worker only needs to place the pipe to be expanded between two protrusions. Then, the pipe can be moved to the designated position by the movement of the conveyor belts. This process allows the device to avoid manual handling of individual pipes for expansion, thereby reducing the labor intensity of workers.

[0006] Preferably, the operating plate has a groove inside, and a slider is slidably connected inside the groove. A movable plate is fixedly installed at the top of the slider, and an expanding head is fixedly installed on one side of the movable plate. A movable block is fixedly installed at the bottom of the slider. Two connecting plates are fixedly installed at the bottom of the operating plate. A screw is rotatably connected between the two connecting plates through a bearing. A second motor is fixedly installed at the bottom of the operating plate. One end of the screw passes through one of the connecting plates and is fixedly connected to the output end of the second motor. When expanding the pipe, the second motor is used to drive the screw to rotate, so that the expanding head can expand the pipe.

[0011] Preferably, the first hydraulic cylinder, the second hydraulic cylinder, the electric push rod, the third hydraulic cylinder, motor one, and motor two are all electrically connected to the control panel.

[0012] This utility model provides a pipe end expansion device, which has the following beneficial effects:

[0013] 1. This pipe end expansion device, through the setting of conveyor belt and protrusions, only requires placing the unexpanded pipe between two protrusions before expansion, and then it can be conveyed to the support block and support plate for expansion. Through this process, there is no need to use manual labor for individual handling and expansion, thus reducing the labor intensity of workers and avoiding injuries to workers when handling pipes.

[0014] 2. The pipe end expansion device, through the setting of the opening and the slide plate, after the pipe is expanded, only two first hydraulic cylinders and two second hydraulic cylinders are used to move the two clamping plates and two support blocks away from each other, so that the expanded pipe will fall from the opening and slide out from the slide plate. Through this process, the device no longer requires manual feeding, thus increasing the automation of the device. Attached Figure Description

[0023] like Figure 1As shown, an L-shaped plate 11 is fixedly installed on the top of one of the fixed plates 2, and a third hydraulic cylinder 12 is fixedly installed on the top of the L-shaped plate 11.

[0028] In summary, when using this pipe end expansion device, first, power on the device. Then, with manual assistance, place the pipe to be expanded onto the two conveyor belts 20. Note that the pipe should be placed between the two protrusions 2001. Then, the operator uses the control panel 30 to activate motor 18, which drives the conveyor roller 19 to rotate, thus driving the two conveyor belts 20 to transport the pipe. Then, stop motor 18, and the pipe will fall onto the two support blocks 8 and a support plate 10, where it can be expanded. Using the control panel 30, activate motor 26, which drives screw 24 to rotate, thereby moving moving block 25. This indirectly moves moving plate 15 to one side of the pipe, until one end of the expansion head 16 is inserted into the pipe. Then, the pipe moves towards one end of clamping plate 5. Simultaneously, the electric push rod 9 moves the support plate 10 downwards. When one end of the pipe enters... When the pipe reaches the area between the two clamping plates 5, the two first hydraulic cylinders 4 drive the two clamping plates 5 to move closer together, thereby clamping one end of the pipe. After clamping, to make the pipe expansion more stable, the third hydraulic cylinder 12 drives the pressure plate 14 to move downward until the outer side of the pipe is locked. Then, the second motor 26 drives the screw 24 to continue rotating, causing the flaring head 16 to continue moving into the pipe, thus flaring the end of the pipe. After flaring is complete, the second motor 26 drives the screw 24 to rotate, causing the flaring head 16 to be inside the pipe. Then, the two first hydraulic cylinders 4 drive the two clamping plates 5 to move away from each other, and the two second hydraulic cylinders 6 drive the two support blocks 8 to move away from each other. The expanded pipe will fall from the opening 27 and slide out of the slide plate 28. Note that to avoid damaging the pipe, a soft pad can be placed at the bottom of the slide plate 28. Then, the first motor 18 continues to work, and the pipe expansion can continue in the above manner. The above is the working principle of this utility model.
