Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe processing technology, specifically to a pipe bending and forming device for processing plastic pipes. Background Technology
[0002] Plastic pipes are typically made of polymer materials such as polyethylene, polypropylene, polyvinyl chloride, and polystyrene. These materials have advantages such as being lightweight, corrosion-resistant, having good insulation properties, and being easy to process, making plastic pipes widely used in many fields.
[0003] Chinese Patent Publication No. CN202779323U discloses a "Pipe Bending Forming Device," comprising a base, two limiting driven wheels, and a driving wheel. The limiting driven wheels are rotatably and symmetrically arranged on the base, with their rotation axes parallel to each other. The driving wheel is height-adjustably positioned on the center line between the two limiting driven wheels. This invention can directly press straight pipes into bends without welding, reducing the workload and achieving high-quality bends.
[0004] While existing technology involves bending, there is no fixing device to ensure the stability of the plastic tube during bending. This makes it prone to axial movement or radial displacement during bending. Furthermore, bending is performed using a hydraulic rod, which causes stress concentration at the point where the extrusion head releases the tube, resulting in a very high risk of tube damage. Utility Model Content
[0005] The purpose of this utility model is to provide a pipe bending and forming device for processing plastic pipes, so as to solve the problems in the above-mentioned background technology, where there is no fixing device to ensure the stability of the plastic pipe during the bending process, which leads to easy axial movement or radial displacement during bending. At the same time, during the use of hydraulic rods for bending, stress concentration occurs at the point of release between the extrusion head and the pipe, resulting in a very high risk of pipe damage.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a pipe bending and forming device for processing plastic pipes, including a table body, a fixing component on the top of the table body, and a bending component on the top of the table body;
[0007] The fixing component includes a fixing block, and a fixing plate is fixedly connected to one side of the outer surface of the fixing block. A rotating rod is rotatably embedded inside the fixing plate, and a transmission gear is fixedly connected to the outer surface of the rotating rod. A rotating ring is fixedly connected to one side of the outer surface of the transmission gear, and a gear plate is toothed on the outer surface of the transmission gear.
[0008] The bending assembly includes a power column, which is rotatably embedded inside a fixed plate. A first rotating plate is fixedly connected to the outer surface of the power column, and a rotating frame is fixedly connected to one side of the outer surface of the first rotating plate. A bending groove is fixedly connected to one side of the outer surface of the rotating frame.
[0009] Preferably, a fixing post is fixedly connected to one side of the outer surface of the first rotating plate, and a fixing ring is fixedly connected to the top of the outer surface of the fixing post. A second rotating plate is fixedly connected to the outer surface of the fixing post, and the second rotating plate is rotatably sleeved on the outer surface of the rotating rod.
[0010] Preferably, a support frame is fixedly connected to the top of the outer surface of the table, and a cylinder is fixedly connected to the top of the outer surface of the support frame. The cylinder has a telescopic column inside, and one side of the outer surface of the telescopic column is fixedly connected to a gear plate.
[0011] Preferably, a large support plate is fixedly connected to the top of the outer surface of the table, and a limiting groove is fixedly connected to one side of the outer surface of the large support plate, and the gear plate is slidably embedded in the limiting groove.
[0012] Preferably, a first support plate is fixedly connected to the top of the outer surface of the table, and a first through groove is fixedly connected to the top of the outer surface of the first support plate; a second support plate is fixedly connected to the top of the outer surface of the table, and a second through groove is fixedly connected to the top of the outer surface of the second support plate.
[0013] Preferably, a motor frame is fixedly connected to the bottom of the outer surface of the table, and a rotary motor is provided on one side of the outer surface of the motor frame. The output shaft of the rotary motor is fixedly connected to the power column. A rotating groove is provided inside the table, and the power column is rotatably embedded in the rotating groove.
[0014] Compared with the prior art, the beneficial effects achieved by this utility model are:
[0015] This invention involves inserting a plastic tube to be bent into a first through-groove, and then into a second through-groove. Once inserted, the tube passes between a fixed ring and a rotating ring, and is thus fixed within the bending groove. To remove the tube, a cylinder is activated. The cylinder, through an internal telescopic column, drives a gear plate to slide within a limiting groove. This sliding of the gear plate rotates a geared transmission gear, which in turn rotates the rotating ring. This rotation releases the plastic tube, allowing it to be removed. This technical solution ensures the tube's position remains stable during bending, thereby improving the accuracy of the bending angle and shape.
[0016] Secondly, when bending is required, this utility model activates a rotary motor, which drives a power column to rotate. The rotation of the power column, in turn, drives a first rotating plate to rotate. The rotation of the first rotating plate drives a fixed column and a rotating frame to rotate. The rotation of the fixed column and the rotating frame, in turn, drives a fixed ring and a bending groove to rotate around the rotating ring. The rotation of the fixed ring and the bending groove bends the plastic tube. During the bending process, the fixed ring and the bending groove rotate around the rotating ring, thus achieving bending. Through the above technical solution, the bending angle is consistent and accurate, and the tube is subjected to uniform stress, avoiding cracks or wrinkles caused by local stress concentration.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-3 A pipe bending forming device for processing plastic pipes includes a table body 1, a fixing component on the top of the table body 1, and a bending component on the top of the table body 1.
[0023] The fixing component includes a fixing block 2, and a fixing plate 201 is fixedly connected to one side of the outer surface of the fixing block 2. A rotating rod 602 is rotatably embedded inside the fixing plate 201, and a transmission gear 601 is fixedly connected to the outer surface of the rotating rod 602. A rotating ring 6 is fixedly connected to one side of the outer surface of the transmission gear 601, and a gear plate 603 is toothed on the outer surface of the transmission gear 601.
[0024] The bending assembly includes a power column 401, which is rotatably embedded inside the fixed plate 201. A first rotating plate 3 is fixedly connected to the outer surface of the power column 401, and a rotating frame 303 is fixedly connected to one side of the outer surface of the first rotating plate 3. A bending groove 304 is fixedly connected to one side of the outer surface of the rotating frame 303.
[0025] The above technical solution involves inserting the plastic tube to be bent into the first through groove 801, and then into the second through groove 803. Once inserted, the plastic tube passes between the fixing ring 5 and the rotating ring 6, and through the bending groove 304, thus securing the plastic tube. To remove the plastic tube, the cylinder 7 is activated. The cylinder 7, through its internal telescopic column 701, drives the gear plate 603 to slide within the limiting groove 704. As the gear plate 603 slides, it drives the geared transmission gear 601 to rotate. This rotation of the transmission gear 601 causes the rotating ring 6 to rotate, releasing the restriction on the plastic tube and allowing it to be removed. This technical solution ensures the tube's position remains stable during bending, thereby improving the accuracy of the bending angle and shape.
[0026] With the above technical solution, when bending is required, the rotary motor 4 is turned on, which drives the power column 401 to rotate. The rotation of the power column 401 drives the first rotating plate 3 to rotate. The rotation of the first rotating plate 3 drives the fixed column 301 and the rotating frame 303 to rotate. The rotation of the fixed column 301 and the rotating frame 303 drives the fixed ring 5 and the bending groove 304 to rotate around the rotating ring 6. The rotation of the fixed ring 5 and the bending groove 304 bends the plastic tube. During the bending process, the fixed ring 5 and the bending groove 304 rotate around the rotating ring 6, thereby achieving bending. With the above technical solution, the bending angle is consistent and accurate, and the tube is subjected to uniform stress, avoiding cracks or wrinkles caused by local stress concentration.
[0027] Specifically, a fixing post 301 is fixedly connected to one side of the outer surface of the first rotating plate 3, and a fixing ring 5 is fixedly connected to the top of the outer surface of the fixing post 301. A second rotating plate 302 is fixedly connected to the outer surface of the fixing post 301, and the second rotating plate 302 is rotatably sleeved on the outer surface of the rotating rod 602.
[0028] Through the above technical solution, the rotation of the first rotating plate 3 drives the fixed column 301 and the rotating frame 303 to rotate. The rotation of the fixed column 301 and the rotating frame 303 then drives the fixed ring 5 and the bending groove 304 to rotate around the rotating ring 6 as the center.
[0029] Specifically, a support frame 702 is fixedly connected to the top of the outer surface of the table body 1, and a cylinder 7 is fixedly connected to the top of the outer surface of the support frame 702. A telescopic column 701 is provided inside the cylinder 7, and one side of the outer surface of the telescopic column 701 is fixedly connected to the gear plate 603.
[0030] Through the above technical solution, by opening the cylinder 7, the cylinder 7 drives the gear plate 603 to slide through the internal telescopic column 701.
[0031] Specifically, a large support plate 703 is fixedly connected to the top of the outer surface of the table body 1, and a limiting groove 704 is fixedly connected to one side of the outer surface of the large support plate 703, and the gear plate 603 is slidably embedded in the limiting groove 704.
[0032] Through the above technical solution, the gear plate 603 slides within the limiting groove 704 and is limited by the limiting groove 704.
[0033] Specifically, a first support plate 8 is fixedly connected to the top of the outer surface of the table body 1, and a first through groove 801 is fixedly connected to the top of the outer surface of the first support plate 8. A second support plate 802 is fixedly connected to the top of the outer surface of the table body 1, and a second through groove 803 is fixedly connected to the top of the outer surface of the second support plate 802.
[0034] Using the above technical solution, the plastic tube that needs to be bent is inserted into the first through groove 801, and then inserted into the second through groove 803 through the first through groove 801. When the plastic tube is inserted into the first through groove 801 and the second through groove 803, it passes right between the fixed ring 5 and the rotating ring 6.
[0035] Specifically, a motor frame 101 is fixedly connected to the bottom of the outer surface of the table body 1, and a rotary motor 4 is provided on one side of the outer surface of the motor frame 101. The output shaft of the rotary motor 4 is fixedly connected to the power column 401. A rotating groove 102 is provided inside the table body 1, and the power column 401 is rotatably embedded in the rotating groove 102.
[0036] The above technical solution uses a rotary motor 4 to drive the power column 401 to rotate.
[0037] In use, the plastic tube to be bent is inserted into the first through groove 801, and then into the second through groove 803. When the plastic tube is inserted into the first and second through grooves 801 and 803, it passes between the fixing ring 5 and the rotating ring 6, and through the bending groove 304, thus fixing the plastic tube. When the plastic tube needs to be removed, the cylinder 7 is activated. The cylinder 7, through its internal telescopic column 701, drives the gear plate 603 to slide within the limiting groove 704. As the gear plate 603 slides, it drives the geared transmission gear 601 to rotate. The rotation of the transmission gear 601 drives the rotating ring 6 to rotate, thereby releasing the restriction on the plastic tube and allowing it to be removed. This technical solution ensures that the tube is properly secured during bending. The position remains stable, thereby improving the accuracy of the bending angle and shape. When bending is required, the rotary motor 4 is turned on, which drives the power column 401 to rotate. The rotation of the power column 401 drives the first rotating plate 3 to rotate. The rotation of the first rotating plate 3 drives the fixed column 301 and the rotating frame 303 to rotate. The rotation of the fixed column 301 and the rotating frame 303 drives the fixed ring 5 and the bending groove 304 to rotate around the rotating ring 6. The rotation of the fixed ring 5 and the bending groove 304 bends the plastic tube. During the bending process, the fixed ring 5 and the bending groove 304 rotate around the rotating ring 6 to achieve bending. Through the above technical solution, the bending angle is consistent and accurate, and the tube is subjected to uniform stress, avoiding cracks or wrinkles caused by local stress concentration.
