Description

A long U-bend device Technical Field

[0001] This utility model belongs to the technical field of pipe bending devices, and in particular relates to a long U-bending pipe device. Background Technology

[0002] A long U-bend pipe bending device, also known as a long U-bend machine, is a complex mechanical device primarily used for bending long pipes. Long U-bend machines are widely used in industries such as petroleum, chemical, power, and construction for producing and processing pipeline systems such as pipes, water pipes, and gas pipes. Their advantages include the ability to complete a large number of pipe bending operations in a short time, high processing precision, and savings in labor costs and processing time.

[0003] However, existing long U-bend devices have a significant problem in use: poor versatility. Specifically, current long U-bend devices on the market can usually only bend pipes of one diameter. Since different industries have different requirements for the diameter of U-shaped pipes, it is often necessary to change to long U-bend devices of different specifications when dealing with pipes of different diameters. This practice greatly increases the cost of using the device.

[0004] Therefore, it is necessary to provide a new long U-bend device to solve the above problems. Summary of the Invention

[0005] This invention provides a long U-bend device, which aims to solve the problem mentioned in the background art that existing long U-bend devices cannot bend pipes of different diameters.

[0006] To solve the above problems, this utility model is implemented as follows: a long U-bend pipe device, comprising: a base plate, two upright plates fixedly mounted on the top of the base plate, each upright plate having a hinged rotating plate, each rotating plate having an installation groove, and each installation groove having an insertion hole on its bottom inner wall; two connecting blocks slidably mounted on the two insertion holes, each connecting block having a slot, each connecting block having a limit plate welded to it, each limit plate having multiple arc-shaped grooves for placing pipes, and each limit plate being adapted to the two installation grooves; a bracket fixedly mounted on the top of the base plate, a screw rotatably mounted on the bracket, and a sleeve threaded onto the screw; a pressure block fixedly mounted on the sleeve by bolts; multiple electric push rods hinged to the base plate, the output rods of the multiple electric push rods being hinged to the two rotating plates respectively; and two positioning mechanisms respectively assembled on the two rotating plates for fixing the connecting blocks.

[0007] Preferably, the positioning mechanism includes: a housing fixedly mounted on the rotating plate, a pull rod slidably mounted on the housing, and a spring slidably sleeved on the pull rod; a baffle fixedly mounted on the pull rod, an insert block welded to the baffle, the insert block being slidably connected to the housing, and the insert block being adapted to the slot.

[0008] Preferably, two limiting blocks are fixedly installed on the outer wall of the sleeve, and limiting rods are slidably installed on both limiting blocks. The top ends of both limiting rods are fixedly connected to the bracket.

[0009] Preferably, a knob is fixedly installed at the top end of the screw, and multiple anti-slip pads are fixedly installed on the knob.

[0010] Preferably, the bracket is L-shaped, and a circular plate is fixedly installed at the bottom end of each of the two limiting rods.

[0011] Preferably, each of the two pull rods has a pull ring fixedly installed at the ends that are far apart from each other, and both springs are made of stainless steel.

[0012] Preferably, a controller is fixedly installed on the top of the base plate, and multiple anti-slip pads are fixedly installed on the bottom of the base plate.

[0013] Compared with related technologies, the long U-bend device provided by this utility model has the following advantages:

[0014] Compared with existing technologies, the long U-bend device provided in this solution, through multiple arc-shaped grooves on two limiting plates, allows personnel to easily and stably place the pipes to be bent onto two rotating plates. By rotating the screw, the sleeve can drive the pressure block to move vertically, allowing the pressure block to contact the surface of the pipe. Multiple electric push rods enable the two rotating plates to rotate on two vertical plates. When the two rotating plates rotate to 90°, multiple pipes can be bent into a U-shape, thus obtaining the corresponding long U-bend. Bending is relatively convenient. Since the pressure block and sleeve are connected by bolts, removing the bolts allows for easy replacement of the appropriate pressure block according to the diameter of the pipe being processed. Furthermore, the use of two positioning mechanisms also allows for easy replacement of the two limiting plates according to the diameter of the pipe being processed, enabling the size of the arc-shaped grooves on the two limiting plates to be changed. This allows the device to bend pipes of different diameters, greatly improving the device's versatility and effectively reducing its operating costs. Attached Figure Description

[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] This utility model embodiment provides a long U-bend device, as shown in Figures 1-4. The long U-bend device includes: a base plate 1, with two upright plates 2 fixedly installed on the top of the base plate 1. A rotating plate 3 is hinged to each of the two upright plates 2, and each of the two rotating plates 3 has a mounting groove. An insertion hole is formed on the bottom inner wall of each of the two mounting grooves. Two connecting blocks 4 are slidably installed on the two insertion holes, each of the two connecting blocks 4 has a locking groove, and a limiting plate 5 is welded to each of the two connecting blocks 4. Each of the two limiting plates 5 has a... There are multiple arc-shaped grooves 6 for placing pipes, and two limiting plates 5 are respectively adapted to the two mounting grooves; a bracket 7 is fixedly installed on the top of the base plate 1, and a screw 8 is rotatably installed on the bracket 7, and a sleeve 9 is threaded on the screw 8; a pressure block 10 is fixedly installed on the sleeve 9 by bolts; multiple electric push rods 11 are hinged to the base plate 1, and the output rods of the multiple electric push rods 11 are respectively hinged to the two rotating plates 3; two positioning mechanisms are respectively assembled on the two rotating plates 3 for fixing the connecting block 4.

[0023] In this embodiment, when using the device, multiple pipes that need to be bent are first placed into the multiple arc-shaped grooves 6 on the two limiting plates 5. Then, the screw 8 is rotated. Since the screw 8 is threadedly connected to the sleeve 9, rotating the screw 8 causes the sleeve 9 to drive the pressure block 10 to move vertically, so that the pressure block 10 contacts the surface of the pipe. After contact, the controller activates multiple electric push rods 11. The multiple electric push rods 11 drive the two rotating plates 3 to rotate on the two vertical plates 2. When the two rotating plates 3 are rotated to 90°, the multiple pipes can be bent into a U-shape, thereby obtaining the corresponding long U-bend pipe. After bending is completed, the output rods of the multiple electric push rods 11 will retract. The two rotating plates 3 are flipped back to their original angles, allowing the worker to remove the bent pipe. Bending is relatively convenient. Since the pressure block 10 and the sleeve 9 are connected by bolts, the bolts can be removed to easily replace the pressure block 10 with the appropriate size according to the diameter of the pipe being processed. With the use of the two positioning mechanisms, the two limiting plates 5 can also be replaced with the appropriate size according to the diameter of the pipe being processed, allowing the size of the arc groove 6 on the two limiting plates 5 to be changed. In this way, the device can bend pipes of different diameters, greatly improving its versatility and effectively reducing the cost of using the device.

[0024] In a further preferred embodiment of the present invention, the positioning mechanism includes: a housing 12 fixedly mounted on the rotating plate 3, a pull rod 13 slidably mounted on the housing 12, and a spring 14 slidably sleeved on the pull rod 13; a baffle 15 fixedly mounted on the pull rod 13, an insert 16 welded on the baffle 15, the insert 16 being slidably connected to the housing 12, and the insert 16 being adapted to the slot.

[0025] In this embodiment, the positioning mechanism is used to fix the connecting block 4. When the limiting plate 5 needs to be replaced, the pull rod 13 is pulled by hand. The pull rod 13 will drive the baffle 15 to squeeze the spring 14. The baffle 15 will drive the insert block 16 to slide on the housing 12 until the insert block 16 disengages from the slot on the connecting block 4. After disengagement, the limiting plate 5 can be removed from the mounting slot. Then, the limiting plate 5 with the corresponding size arc groove 6 is replaced. The connecting block 4 at the bottom of the limiting plate 5 is inserted into the insertion hole. Then, the pull rod 13 is released so that the spring 14 can push the baffle 15 to move through elasticity, so that the insert block 16 on one side of the baffle 15 can be inserted into the slot on the connecting block 4. After insertion, the connecting block 4 can be fixed, and the replacement of the limiting plate 5 is completed.

[0026] In a further preferred embodiment of the present invention, two limiting blocks 17 are fixedly installed on the outer wall of the sleeve 9, and limiting rods 18 are slidably installed on both limiting blocks 17. The top ends of both limiting rods 18 are fixedly connected to the bracket 7.

[0027] In this embodiment, the stability of the sleeve 9 and the pressure block 10 during vertical movement can be ensured by the cooperation of two limiting blocks 17 and two limiting rods 18. When the sleeve 9 and the pressure block 10 move vertically, the two limiting blocks 17 connected to the sleeve 9 will slide vertically on the two limiting rods 18 respectively.

[0028] In a further preferred embodiment of the present invention, a knob 19 is fixedly installed on the top end of the screw 8, and a plurality of anti-slip plates are fixedly installed on the knob 19.

[0029] In this embodiment, the use of a knob and multiple anti-slip pads makes it easy for personnel to rotate the screw 8 and prevents it from slipping.

[0030] In a further preferred embodiment of this utility model, the bracket 7 is configured as an L-shape, and a circular plate is fixedly installed at the bottom end of each of the two limiting rods 18.

[0031] In this embodiment, the L-shaped bracket 7 facilitates the removal of the bent pipe, and the use of two circular plates effectively prevents the two limiting blocks 17 from disengaging from the two limiting rods 18 due to excessive downward movement.

[0032] In a further preferred embodiment of this utility model, pull rings are fixedly installed at the ends of the two pull rods 13 that are far apart from each other, and the two springs 14 are made of stainless steel.

[0033] In this embodiment, the use of two pull rings makes it convenient for people to pull the two levers 13 by hand. The stainless steel spring 14 has good durability, will not rust, and has a good service life.

[0034] In a further preferred embodiment of the present invention, a controller is fixedly installed on the top of the base plate 1, and multiple anti-slip pads are fixedly installed on the bottom of the base plate 1.

[0035] In this embodiment, the controller allows people to easily control the device, and multiple anti-slip pads ensure that the device can be stably placed on the ground for use.

[0036] In summary, compared with related technologies, this solution, through multiple arc-shaped grooves 6 on the two limiting plates 5, allows personnel to stably place the pipes to be bent onto the two rotating plates 3. By rotating the screw 8, the sleeve 9 can drive the pressure block 10 to move vertically, allowing the pressure block 10 to contact the surface of the pipe. Through the use of multiple electric push rods 11, the two rotating plates 3 can rotate on the two vertical plates 2. When the two rotating plates 3 are rotated to 90°, multiple pipes can be bent into a U-shape, thereby obtaining the corresponding long U-bend pipe. Bending is relatively convenient. Since the pressure block 10 and the sleeve 9 are connected by bolts, by removing the bolts, it is convenient to replace the pressure block 10 of the appropriate specification according to the diameter of the pipe being processed. Furthermore, with the use of two positioning mechanisms, it is also convenient to replace the two limiting plates 5 of the appropriate specification according to the diameter of the pipe being processed, so that the size of the arc-shaped grooves 6 on the two limiting plates 5 can be changed. In this way, the device can bend pipes of different diameters, greatly improving the versatility of the device and effectively reducing the operating cost of the device.
