Description

Technical Field

[0001] This utility model relates to a device for pipe processing and forming, and more particularly to an adaptive pipe pressing device. Background Technology

[0002] During the installation and use of pipelines, bending is often necessary to adapt to the spatial layout of the application scenario. This allows the pipelines to better fit the shape of the working equipment and environment, avoiding conflicts between components and structures during equipment operation. The pipeline route can also better meet the production process and technological requirements. In pipeline bending, large-radius bends can reduce the resistance encountered by the fluid at the bend, increase flow rate, reduce pipeline fatigue during use, and improve pipeline safety and reliability. At the same time, for pipelines that have undergone bending deformation during production or transportation, straightening is required to ensure installation accuracy and functionality.

[0003] In existing pipe pressing operations, operators typically use tools such as pipe bending machines to manually bend or straighten round pipes. This method suffers from inconsistent bending angles, complex operations that increase workload, difficulty in supporting large-radius pipe bends, and an inability to simultaneously handle both bending and straightening operations. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an adaptive pipe pressing device. The operator positions the pipe to be pressed into a bend or the bend to be pressed into a straight section directly above the top surface of the support plate of the top column. The operator, according to the required curvature of the pipe, pushes the handle to rotate the rotating component a corresponding number of times. The rotating component drives the top column to rise. During the process of the pipe being pushed upward by the support plate, it is blocked by a baffle. The baffle rotates through a connected bearing, adapting to the change in the inclination of the pipe body. This allows for simpler and more flexible bending and fixing of pipes requiring a larger radius of curvature.

[0005] This utility model is achieved through the following technical solution:

[0006] An adaptive pipe pressing device includes a frame and a support. The support is connected to one side of the upper part of the frame. A sleeve is connected to the top surface of the bottom of the frame below the support. A bearing is connected to the top of the sleeve. A rotating component is connected to the top of the bearing. A handle is connected to the side of the rotating component. A top column is slidably connected to the inner side of the sleeve. The top column passes through the center of the rotating component and is threadedly connected to the rotating component. Two bearings parallel to the side of the frame are connected to the support at the same height on both sides of the top column. A baffle is connected to the outer side of the bearing.

[0007] Furthermore, the sleeve includes a body and a groove, with the groove vertically connected to the inner side of the body.

[0008] Furthermore, the rotating component is a nut, the central axis of the threaded hole of the rotating component coincides with the central axis of the sleeve, and the bottom surface of the inner ring and the top surface of the outer ring of bearing one are connected to the top surface of the sleeve and the bottom surface of the rotating component, respectively.

[0009] Furthermore, the top column includes a support plate, a bolt, and a slider. The support plate is a U-shaped plate with an open top surface facing upwards and both ends bent downwards. The support plate is connected to the top of the bolt, and the top open side of the support plate is parallel to the side of the frame opposite to the sleeve.

[0010] Furthermore, the length of the bolt is equal to the height of the inner side of the sleeve plus the height of the rotating part, and the bolt and the rotating part are connected by threads.

[0011] Furthermore, the slider is connected to the bottom end of the bolt, and the shape of the slider is adapted to the shape of the groove, so that the slider and the groove are slidably connected.

[0012] Furthermore, the inner ring of bearing two is connected to the bracket, and the center points of the two bearings two are on the same vertical plane as the central axis of the top column and are symmetrical about the central axis of the top column.

[0013] Furthermore, the baffle is a U-shaped plate, with the top side of the baffle opening parallel to the side of the frame opposite to the sleeve, and the inner curvature of the baffle is the same as that of the inner curvature of the pallet.

[0014] Compared with the prior art, this utility model has the following obvious advantages:

[0015] I. In this utility model, the top column is slidably connected to the inside of the sleeve and connected to the rotating part by a thread. The rotating part is rotatably connected to the top of the sleeve by a bearing. The operator can push the handle to rotate the rotating part, and push the top column upward by the thread, so that the pipe placed at the top of the top column can rise stably. Compared with the operator manually controlling the bending displacement distance of the pipe, this is more accurate and saves manpower.

[0016] II. In this utility model, the top column includes a support plate connected to the top. The support plate is a U-shaped plate with an open top surface facing upward and both ends bent downward. The brackets on both sides above the support plate are connected to bearings II. The outer surface of the bearings II is connected to baffles. When the pipe is pushed to the height position of the baffles, the bottom of the pipe to be bent and the top of both ends of the pipe to be bent are blocked by the support plate and the baffles respectively. After the top column continues to rise, it pushes the pipe to be bent to be bent in the arc of the top surface of the support plate, thus realizing a simple and effective large arc radius bending of the pipe.

[0017] Third, because the baffle is connected to the outer ring surface of the bearing two, the inner side curvature of the support plate and the baffle is the same, and the top side of the opening of the support plate and the baffle is parallel to the side of the frame and the sleeve opposite to each other, when the pipe is under pressure, the baffle always keeps its inner side in contact with the surface of the pipe during the rotation of the bearing two, which can ensure the stability of the position of the pipe during the pressing process, and can also straighten the bent pipe in addition to the pipe bending operation.

[0022] The present invention will now be described in detail with reference to the accompanying drawings.

[0023] like Figure 1 and Figure 2As shown, this utility model provides an adaptive pipe pressing device, including a frame 1, a sleeve 2, a first bearing 3, a rotating component 4, a handle 5, a top column 6, a support 7, a second bearing 8, and a baffle 9. In this embodiment, the support 7 is connected to one side of the upper part of the frame 1, and the sleeve 2 is connected to the top surface of the bottom of the frame 1 below the support 7. The sleeve 2 includes a cylinder body 201 and a slide groove 202. The slide groove 202 is vertically connected to the inner side of the cylinder body 201. The rotating component 4 is a nut, which is rotatably connected to the top of the sleeve 2 through the first bearing 3. The bottom surface of the inner ring and the top surface of the outer ring of the first bearing 3 are respectively connected to the top of the sleeve 2 and the bottom surface of the rotating component 4. The handle 5 is vertically connected to the side of the rotating component 4. The top column 6 includes a support plate 601, a bolt 602, and a slider 603. The support plate 601 is a U-shaped plate with the top opening facing upward and both ends bent downward. The bottom end of the support plate 601 is connected to the top end of the bolt 602. The top opening side of the support plate 601 is flat. Located on the side of the frame 1 opposite to the sleeve 2, bolt 602 vertically passes through the center of the top surface of the rotating part 4 and is connected to the rotating part 4 by threads. The length of bolt 602 is equal to the height of the inner side of the sleeve 2 plus the height of the rotating part 4. Slider 603 is connected to the bottom end of bolt 602. The shape of slider 603 is adapted to the shape of slide groove 202. Top column 6 is slidably connected to slide groove 202 of sleeve 2 through slider 603. The inner rings of two bearings 8 are connected to the brackets 7 directly above the top column 6 on both sides at the same height. Bearings 8 are parallel to the side of frame 1. The center point of the two bearings 8 is on the same vertical plane as the central axis of top column 6 and is symmetrical about the central axis of top column 6. Baffle 9 is a U-shaped plate. The bottom end of the outer side of baffle 9 is connected to the outer ring side of bearing 8. The top side of the opening of baffle 9 is parallel to the side of frame 1 opposite to sleeve 2. The curvature of the inner side of baffle 9 is the same as the curvature of the inner side of support plate 601.

[0024] The working principle of this utility model is as follows:

[0025] In use, in the initial state of the device, the threaded tip of bolt 602 is connected to rotating component 4. To perform a straight pipe bending operation, the operator pushes handle 5 clockwise, causing rotating component 4 to rotate clockwise. Sliding block 603 stabilizes the horizontal state of the top column 6, allowing it to rise continuously under the push of the thread. When the vertical distance between the top surface of the support plate 601 and the side of the opening of the baffle 9 is close to the cross-sectional diameter of the pipe 10, the operator stops pushing handle 5 and places the pipe 10 on the top surface of support plate 601 with the bending position aligned with the vertical axis of the top column 6. After placing the pipe 10, the operator continues to push handle 5 clockwise until the pipe is bent. When the pipe 10 rises to the position where the inner side of the baffle 9 is in contact with the top surface of the pipe 10, the operator continues to push the handle 5 according to the angle that the pipe 10 needs to be bent, so that the rotating part 4 rotates the corresponding number of times. Under the rotation of the bearing 8, the inner side of the baffle 9 is always in contact with the non-bent parts on both sides of the bend of the pipe 10, limiting the position of the non-bent parts of the pipe 10. The top column 6 pushes the bend of the pipe 10, so that the bend of the pipe 10 is pressed and bent against the inner arc of the support plate 601. After the pipe 10 is bent, the operator pushes the handle 5 counterclockwise, so that the top column 6 is lowered and reset under the pushing action of the thread, and the bent pipe 10 is removed from the support plate 601.

[0026] To straighten the pipe, the operator pushes handle 5 clockwise, causing rotating part 4 to rotate clockwise. Slider 603 stabilizes the horizontal position of the top column 6, allowing it to rise continuously under the push of the thread. When the vertical distance between the top side of the opening of the support plate 601 and the baffle 9 is approximately twice the cross-sectional diameter of the pipe 10, the operator stops pushing handle 5. The operator aligns the curved position of the pipe 10 with the vertical axis of the top column 6, placing the pipe 10 with the curved protrusion facing downwards and the pipe body parallel to the side of the frame 1 opposite the sleeve 2 on the top surface of the support plate 601. After placing the pipe 10, the operator continues to push handle 5 clockwise until the pipe 10 rises to the baffle 9. The inner side of the pipe 10 is in contact with the top surface of the pipe 10. The pipe 10 is limited between the support plate 601 and the baffle 9. The operator continues to push the handle 5. Under the rotation of the bearing 8, the inner side of the baffle 9 is always in contact with the straight pipe parts on both sides of the bend of the pipe 10, limiting the position of the straight pipe parts on both sides of the bend of the pipe 10 and the overall position of the pipe 10. The top column 6 pushes the bend of the pipe 10, so that the bend of the pipe 10 is bent in the opposite direction by the support plate 601, thereby gradually straightening the bend of the pipe 10. After the pipe 10 is straightened, the operator pushes the handle 5 counterclockwise, so that the top column 6 is lowered and reset under the pushing action of the thread, and the straightened pipe 10 is removed from the support plate 601.

[0027] In the above-mentioned pipe 10 pressing operation, the pipe 10 made of metal can be directly pressed into shape. For the pipe 10 made of plastic, the operator needs to use a hot air blower to heat and soften the part to be bent before placing the pipe 10 on the device. After the pipe 10 is bent or straightened, wait for it to cool and solidify before lowering the support plate 601 to release the pipe 10.

They should not be construed as limiting the scope of protection of this utility model. All equivalent transformations or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
