Description
Technical Field
[0001] This utility model relates to the field of corrugated pipe forming technology, and in particular to a servo hydraulic pressure precision control module for corrugated pipe forming of automotive parts. Background Technology
[0002] When manufacturing corrugated pipes for automotive parts, servo hydraulic pressure systems are often used for corrugated pipe forming. This is a key piece of equipment in the automotive manufacturing process, primarily used for high-precision forming of flexible tubing such as corrugated pipes. Its core function is to precisely adjust and control the water pressure through servo control technology, ensuring efficient and stable water pressure application during the corrugated pipe forming process.
[0003] Typically, a servo hydraulic pressure precision control module for corrugated pipe forming in automotive parts consists of a hydraulic pressure control valve, a water tank, and a hydraulic pump. During operation, the hydraulic pressure control valve regulates the inlet and outlet water flow to control the water pressure within the corrugated pipe, ensuring that the water pressure remains within the set range during the forming process to promote stable corrugated pipe forming. The water tank, as a liquid storage source, provides a stable water supply, ensuring sufficient water volume during system operation and preventing processing interruptions or instability due to water shortage. The hydraulic pump is responsible for transporting water from the water tank to the corrugated pipe forming process.
[0004] However, in some existing devices, the rotation accuracy of the water pressure control valve is low, which makes it impossible to achieve precise water pressure control when adjusting the water flow. This lack of precise adjustment capability often causes water pressure fluctuations, which directly affect the forming quality of the bellows and may even lead to product defects. To address this issue, a servo water pressure precision control module for bellows forming in automotive parts is proposed. Utility Model Content

A servo motor 501 is fixedly connected to the side, and its design provides good driving capability. The output end of the servo motor 501 is fixedly connected to a connecting block 502. The servo motor 501 provides driving capability to the connecting block 502, causing the connecting block 502 to rotate. The outside of the connecting block 502 is inside the connecting tube 506. The top and bottom of the connecting block 502 are rotatably connected to rotating columns 503, and their design provides good rotation capability. The outside of the two rotating columns 503 is fixedly connected to a fixing plate 504. The rotation of the rotating columns 503 can drive the fixing plate 504 to rotate. The two fixed plates 504 are fixedly connected to the top of the rolling ball 505. Through its own rolling characteristics, it can make a mark on the inside of the processing pipe, which can provide precise positioning and facilitate water pressure to expand it. When water pressure is injected from the same end of the servo motor 501, the fixed plate 504 can be unfolded. Then, the inner wall of the processing pipe can be rotated by the rotation of the servo motor 501. The top of the sliding mechanism 3 is provided with a fixed mechanism 4, and the top of the base 1 is provided with a control mechanism 6.

When the opening and closing column 605 needs to be rotated accurately, the sliding column 6012 is slid into the alignment grooves 6013, and then the opening and closing column 605 is rotated. During the rotation, the pointer 6011 can be locked on the top of the sliding column 6012 to prevent over-rotation that would lead to inaccurate control.
[0037] Reference Figure 1 and Figure 3The fixing mechanism 4 includes two push rods 406, designed to provide good telescopic capability. The two push rods 406 are externally fixedly connected to the top sides of the end placement plate 303. Connecting columns 404 are fixedly connected to the front outer sides of the two push rods 406, designed to provide good connection capability. Arc-shaped plates 401 are fixedly connected to adjacent sides of the two connecting columns 404. The arc-shaped plates 401 can fix the other end of the processing pipe, preventing displacement during water pressure processing. Abutment plates 403 are fixedly connected inside the two arc-shaped plates 401, which can fix the other side of the processing pipe. The interior is sealed, and the bottom of the two connecting columns 404 is fixedly connected to the sliders 405, which are designed to provide good sliding ability. The top of the end plate 303 is fixedly connected to two sliding rods 407, which are designed to provide good sliding space for the sliders 405. The bottom of the two sliders 405 are slidably connected to the inside of the sliding rods 407 respectively. The top of the end plate 303 is slidably connected to multiple push rods 402. The push rods 402 can provide good auxiliary sliding when the arc plate 401 opens and closes, preventing it from falling. The outside of the two push rods 406 are respectively on the adjacent side of the multiple push rods 402.
[0038] Working principle: First, the operator places one end of the pipe to be processed on the clamping plate 2, ensuring it aligns with the connecting pipe 506. Then, the servo motor 501 starts, driving the connecting block 502 to rotate. The rotating column 503 drives the fixing plate 504 to rotate inside the pipe. This process utilizes the characteristics of the rolling ball 505 to leave pre-marks inside the pipe, providing precise positioning for subsequent hydraulic molding. After the fixing plate 504 is positioned, the operator starts the water pump 603, drawing water from the water tank 604 into the delivery pipe 601, ready to be injected into the processed pipe. The water valve 602 regulates the water flow rate by controlling its flow state. During water delivery, the opening and closing column 605 controls the gate plate inside the water valve 602 to regulate the water flow. The operator can accurately measure the rotation angle by rotating the opening and closing column 605 and using the scale 607 on the placement ring 606 to ensure the accuracy of water flow adjustment. When performing more precise water flow control, the operator slides the sliding column 6012 into the alignment groove 6013 at the top of the fixing ring 608, and then rotates the opening and closing column 605. When rotated to the designated position, the pointer 6011 will be stuck at the top of the sliding column 6012, preventing inaccurate control caused by excessive rotation of the opening and closing column 605. The design of the sliding column 6012 ensures fixation during adjustment, while the rotating ring 609 supports the opening and closing column 605, facilitating its smooth rotation and adjusting the opening and closing of the water valve 602, thereby adjusting the intensity of the water flow.
[0039] When the hydrostatic forming of the corrugated pipe begins, the end plate 303 is first securely fixed to one end of the pipe to be processed. Two push rods 406 are activated; with their excellent telescopic capability, the push rods 406 extend outwards and are fixed to the top two sides of the end plate 303, providing necessary support for subsequent fixing operations. As the push rods 406 extend, the connecting column 404 connected to their outer front side is also pushed, causing the arc-shaped plate 401 to move towards the other end of the pipe to be processed, forming a clamping and fixing of the pipe. The design of the arc-shaped plate 401 effectively prevents pipe displacement during hydrostatic processing, maintaining its stability. Simultaneously, the interior of the arc-shaped plate 401... The abutment plate 403 seals the other side of the pipe to ensure no leakage during water pressure processing. In addition, the design of the slider 405 makes the movement of the arc plate 401 smoother. The slider 405 is slidably connected to the slide rod 407, providing good sliding ability and ensuring that the clamping action of the arc plate 401 is accurate and in place. When the arc plate 401 opens and closes, the presence of multiple push rods 402 further assists the sliding and prevents the phenomenon of falling due to gravity. Subsequently, when the water pressure causes the pipe to bulge, the internal water source is extracted, and the hydraulic cylinder 304 is pushed again to push the end placement plate 303 again. Under the fixation of the arc plate 401, the bulging area can be squeezed to form ripples.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
