Description
Technical Field
[0001] This utility model relates to the field of PE pipe production technology, and in particular to a variable diameter flaring machine for PE pipe production. Background Technology
[0002] PE pipe, or polyethylene pipe, is polymerized from ethylene and can be classified into various types according to its application and density. It features reliable connections, good impact resistance, strong corrosion resistance, aging resistance, excellent flexibility, convenient handling, and diverse construction methods. It is widely used in municipal engineering for water supply, gas transmission, and sewage treatment; in building engineering for water supply, drainage, heating, and electrical and telecommunications protection; in agriculture for irrigation and water diversion; in industry for transporting chemical media and minerals; and in the power sector for wiring construction. Connection methods include butt fusion welding, saddle-type butt welding, and steel-plastic flange connections.
[0003] In the production of PE pipes, flaring is required. However, most current flaring mechanisms are relatively simple and lack the function of adjusting the flaring diameter. Frequent replacements are needed when flaring PE pipes with different process requirements, which affects work efficiency. Moreover, the installation between the flaring mechanism and the motor is mostly done with bolts. Although this method is simple to operate, it is time-consuming and inconvenient for maintenance and cleaning. Therefore, this application proposes a variable diameter flaring machine for PE pipe production to meet the requirements. Utility Model Content
[0004] To overcome the shortcomings of existing devices that cannot adjust the flaring diameter and that take a long time to install and disassemble, this utility model provides a variable diameter flaring machine for PE pipe production.
[0005] The technical implementation scheme of this utility model is as follows: a variable diameter flaring machine for PE pipe production, including a base, a motor mounted on the top of the base, a mounting seat fixedly connected to one end of the drive shaft of the motor, a mounting rod provided on one side of the mounting seat, four sets of flaring plates provided on the end of the mounting rod away from the mounting seat, the end of the flaring plate away from the mounting seat being rotatably connected to the mounting rod, an adjustment component provided on the side of the flaring plate close to the mounting seat, and an installation component provided at the connection between the mounting rod and the mounting seat.
[0006] Optionally, the adjustment assembly includes an adjustment ring, a connecting rod, an adjustment groove, and an adjustment block. The adjustment ring is slidably connected to the outer periphery of the mounting rod. The two ends of the connecting rod are respectively rotatably connected to the side of the flared plate near the mounting seat and the side of the adjustment ring away from the mounting seat. The adjustment groove is formed on the outer peripheral surface of the mounting rod. The adjustment block is fixedly connected to the inner side of the adjustment ring and slidably connected to the adjustment groove.
[0007] Optionally, the adjustment assembly further includes fixing holes, vertical grooves, and fixing rods. The fixing holes are provided in several sets and are opened on the inner wall of the bottom of a set of adjustment grooves. The vertical grooves pass through the adjustment ring and a set of adjustment blocks. The fixing rods are movably connected to the vertical grooves and are adapted to the size of the fixing holes.
[0008] Optionally, the adjustment assembly further includes a first slide groove, a first slider, a first spring, and a pull block. The first slide groove is formed on the inner wall of the vertical groove. The first slider is fixedly connected to the outer periphery of the fixed rod and slidably connected to the first slide groove. The first spring is sleeved on the outer periphery of the fixed rod and its two ends are respectively fixedly connected to the top of the first slider and the inner wall of the top of the first slide groove. The pull block is fixedly connected to the top of the fixed rod.
[0009] Optionally, the mounting assembly includes a slot, a mounting groove, a cavity, a through groove, and a mounting block. The slot is located in the middle of the side of the mounting base away from the motor and is adapted to the size of the mounting rod. The mounting groove is located on the outer periphery of the end of the mounting rod near the mounting base. The cavity is annular and located inside the mounting base. The through groove passes through the inner wall of the cavity near the slot. The mounting block is slidably connected to the through groove and is adapted to the size of the mounting groove.
[0010] Optionally, the mounting assembly further includes a rotating ring, a top block, a second slide groove, a second slider, and a second spring. The rotating ring is rotatably connected to the cavity, the top block is fixedly connected to the side of the rotating ring near the through groove, the second slide groove is opened on the side of the mounting base away from the motor and communicates with the cavity, the second slider is fixedly connected to the rotating ring and slidably connected to the second slide groove, and the second spring is installed inside the second slide groove with its two ends respectively fixedly connected to one side of the second slider and one side of the inner wall of the second slide groove.
[0011] Optionally, the mounting assembly further includes a third slide groove, a third slider, and a third spring. The third slide groove is formed on the inner wall of one side of the cavity and is located on the side of the mounting block. The third slider is fixedly connected to the mounting block and slidably connected to the third slide groove. The third spring is installed inside the third slide groove and its two ends are respectively fixedly connected to the inner wall of the third slider near the through groove and the inner wall of the third slide groove near the through groove. The elastic force of the second spring is greater than the sum of the elastic forces of multiple sets of third springs.
[0012] This utility model has the following advantages:
[0013] 1. This utility model features an adjustment component. Pulling the pull block upward causes it to slide the first slider along the first groove via the fixed rod, compressing the first spring. When the fixed rod moves out of the fixed hole, it pushes the adjustment ring along the mounting rod, causing the adjustment block to slide synchronously along the adjustment groove. During this process, the adjustment ring adjusts the angle of the flared piece via the connecting rod. When the flared piece reaches the appropriate angle, the pull block is released, the first spring rebounds, and the fixed rod moves downward via the first slider. When the fixed rod is inserted into the fixed hole at the current position, the adjustment ring is fixed in the current position, thus maintaining the current angle of the flared piece. This design allows the device to perform flaring of PE pipes to different sizes by adjusting the angle of the flared piece, thus broadening its applicability.
[0014] 2. This utility model features an installation assembly. The second slider slides along the second groove, compressing the second spring. During this process, the rotating ring drives the top block to move synchronously within the cavity with the second slider. When the top block moves away from the rear of the mounting block, the third spring rebounds and, through the third slider, drives the mounting block into the cavity. When the mounting block is submerged in the through groove, the end of the mounting rod furthest from the flared piece is placed in the empty groove, aligning the mounting groove with the mounting block. Then, the second slider is released, and the second spring rebounds, driving the rotating ring and top block to move in opposite directions. When the top block contacts the mounting block, it pushes the mounting block out towards the empty groove. When the mounting block is inserted into the mounting groove, the mounting rod is fixed within the empty groove, thus completing the installation of the flaring mechanism. This design makes the installation and disassembly of the flaring mechanism simpler and faster, facilitating its maintenance and cleaning. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, a further detailed description of this utility model will be provided below in conjunction with the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside that appear or will appear in this document are based solely on the accompanying drawings and are not intended to specifically limit this utility model.
[0023] A variable diameter flaring machine for PE pipe production includes a base 1, a motor 2 mounted on the top of the base 1, a mounting base 3 fixedly connected to one end of the drive shaft of the motor 2, a mounting rod 4 on one side of the mounting base 3, four sets of flaring plates 5 on the end of the mounting rod 4 away from the mounting base 3, the end of the flaring plate 5 away from the mounting base 3 being rotatably connected to the mounting rod 4, an adjustment component 6 on the side of the flaring plate 5 close to the mounting base 3, and an installation component 7 at the connection between the mounting rod 4 and the mounting base 3.
[0024] It should be noted that the adjustment component 6 can adjust the angle of the flaring plate 5, thereby enabling the PE pipe to be flared into different diameters. The installation component 7 makes the installation and disassembly of the flaring mechanism simpler and faster, thereby improving its maintenance and cleaning efficiency.
[0025] like Figure 2 and Figure 3 As shown, the adjustment assembly 6 includes an adjustment ring 61, a connecting rod 62, an adjustment groove 63, and an adjustment block 64. The adjustment ring 61 is slidably connected to the outer periphery of the mounting rod 4. The two ends of the connecting rod 62 are rotatably connected to the side of the flared piece 5 near the mounting base 3 and the side of the adjustment ring 61 away from the mounting base 3, respectively. The adjustment groove 63 is opened on the outer periphery surface of the mounting rod 4. The adjustment block 64 is fixedly connected to the inner side of the adjustment ring 61 and slidably connected to the adjustment groove 63.
[0026] It should be noted that by sliding the adjusting ring 61 along the mounting rod 4, the adjusting block 64 can be driven to slide synchronously along the adjusting groove 63, thereby adjusting the angle of the flared piece 5 through the connecting rod 62.
[0027] like Figure 3As shown, the adjustment assembly 6 also includes a fixing hole 65, a vertical groove 66 and a fixing rod 67. The fixing hole 65 is provided in several sets and is opened on the bottom inner wall of a set of adjustment grooves 63. The vertical groove 66 passes through the adjustment ring 61 and a set of adjustment blocks 64. The fixing rod 67 is movably connected to the vertical groove 66 and is adapted to the size of the fixing hole 65.
[0028] It should be noted that the adjusting ring 61 can be slid by removing the fixing rod 67 from the fixing hole 65, and the adjusting ring 61 can be fixed in the current position by inserting the fixing rod 67 into the fixing hole 65.
[0029] like Figure 3 As shown, the adjustment assembly 6 also includes a first slide groove 68, a first slider 69, a first spring 610, and a pull block 611. The first slide groove 68 is formed on the inner wall of the vertical groove 66. The first slider 69 is fixedly connected to the outer periphery of the fixed rod 67 and slidably connected to the first slide groove 68. The first spring 610 is sleeved on the outer periphery of the fixed rod 67 and its two ends are respectively fixedly connected to the top of the first slider 69 and the top inner wall of the first slide groove 68. The pull block 611 is fixedly connected to the top of the fixed rod 67.
[0030] It should be noted that pulling the pull block 611 upwards will cause the first slider 69 to slide upwards along the first slide groove 68 via the fixed rod 67 and compress the first spring 610. Releasing the pull block 611 will cause the first spring 610 to rebound and cause the fixed rod 67 to move downwards via the first slider 69.
[0031] like Figure 2 and Figure 4 As shown, the mounting assembly 7 includes a slot 71, a mounting groove 72, a cavity 73, a through groove 74, and a mounting block 75. The slot 71 is located in the middle of the side of the mounting base 3 away from the motor 2 and is adapted to the size of the mounting rod 4. The mounting groove 72 is located on the outer periphery of the end of the mounting rod 4 near the mounting base 3. The cavity 73 is annular and is located inside the mounting base 3. The through groove 74 passes through the inner wall of the cavity 73 near the slot 71. The mounting block 75 is slidably connected to the through groove 74 and is adapted to the size of the mounting groove 72.
[0032] It should be noted that the end of the mounting rod 4 near the mounting base 3 is placed in the empty groove 71, and then the mounting block 75 is slid along the through groove 74. When the mounting block 75 is inserted into the mounting groove 72, the mounting rod 4 can be fixed in the empty groove 71, thereby completing the installation of the flaring mechanism.
[0033] like Figure 4 and Figure 5As shown, the mounting assembly 7 also includes a rotating ring 76, a top block 77, a second slide groove 78, a second slider 79, and a second spring 710. The rotating ring 76 is rotatably connected to the cavity 73, and the top block 77 is fixedly connected to the side of the rotating ring 76 near the through groove 74. The second slide groove 78 is opened on the side of the mounting base 3 away from the motor 2 and communicates with the cavity 73. The second slider 79 is fixedly connected to the rotating ring 76 and slidably connected to the second slide groove 78. The second spring 710 is installed inside the second slide groove 78 and its two ends are respectively fixedly connected to one side of the second slider 79 and the inner wall of one side of the second slide groove 78.
[0034] It should be noted that when the second slider 79 is slid along the second slide groove 78 to compress the second spring 710, the rotating ring 76 will drive the top block 77 to move synchronously with the second slider 79 in the cavity 73. When the second slider 79 is released, the second spring 710 will rebound and drive the rotating ring 76 and the top block 77 to move in the opposite direction through the second slider 79.
[0035] like Figure 6 As shown, the mounting assembly 7 also includes a third slide groove 711, a third slider 712, and a third spring 713. The third slide groove 711 is opened on the inner wall of one side of the cavity 73 and is located on the side of the mounting block 75. The third slider 712 is fixedly connected to the mounting block 75 and slidably connected to the third slide groove 711. The third spring 713 is installed inside the third slide groove 711 and its two ends are respectively fixedly connected to the inner wall of the third slider 712 near the through groove 74 and the inner wall of the third slide groove 711 near the through groove 74. The elastic force of the second spring 710 is greater than the sum of the elastic forces of multiple sets of third springs 713.
[0036] It should be noted that when the second spring 710 is compressed, the top block 77 moves away from the rear of the mounting block 75. At this time, the third spring 713 rebounds and drives the mounting block 75 to move into the cavity 73 through the third slider 712. When the second spring 710 is not compressed and rebounds, the top block 77 moves to the rear of the mounting block 75. Since the elastic force of the second spring 710 is greater than the sum of the elastic forces of multiple sets of third springs 713, the top block 77 will push the mounting block 75 towards the empty groove 71 and compress the third spring 713 through the third slider 712.
[0037] In a specific application scenario, the second slider 79 first slides along the second groove 78 to compress the second spring 710. During this process, the rotating ring 76 drives the top block 77 to move synchronously with the second slider 79 within the cavity 73. When the top block 77 moves away from behind the mounting block 75, the third spring 713 rebounds and drives the mounting block 75 into the cavity 73 via the third slider 712. When the mounting block 75 is submerged in the through groove 74, the end of the mounting rod 4 away from the flared piece 5 is placed in the cavity 71, and the mounting groove 72 is opened. Aligning with mounting block 75, the second slider 79 is then released. The second spring 710 rebounds and, through the second slider 79, drives the rotating ring 76 and the top block 77 to move in the opposite direction. When the top block 77 contacts mounting block 75, because the elastic force of the second spring 710 is greater than the sum of the elastic forces of multiple sets of third springs 713, the top block 77 will push mounting block 75 towards the empty slot 71 and, through the third slider 712, compress the third spring 713. When mounting block 75 is inserted into mounting slot 72, mounting rod 4 is fixed in empty slot 71. This completes the installation of the flaring mechanism. Then, the motor 2 is started, causing it to rotate the mounting base 3 via the drive shaft. The mounting base 3, in turn, rotates the mounting rod 4 via the mounting block 75. The mounting rod 4 then rotates the flaring piece 5, initiating the flaring process. When it is necessary to flare the PE pipe to different sizes, the pull block 611 is pulled upwards, causing it to slide upwards along the first slide groove 68 via the fixing rod 67, compressing the first spring 610. When the fixing rod 67 moves out of the fixing hole 65, it pushes the adjusting ring 6 along the mounting rod 4. 1. This causes the adjusting block 64 to slide synchronously along the adjusting groove 63. During this process, the adjusting ring 61 will adjust the angle of the flared piece 5 through the connecting rod 62. When the flared piece 5 reaches the appropriate angle, the pulling block 611 is released, the first spring 610 rebounds and drives the fixing rod 67 to move downward through the first slider 69. When the fixing rod 67 is inserted into the fixing hole 65 at the current position, the adjusting ring 61 can be fixed at the current position, so that the flared piece 5 maintains the current angle. At this time, the PE pipe can be flared to a new size.
