Description

Technical Field

[0001] This utility model relates to the field of sleeve flaring devices, specifically a building metal sleeve flaring device. Background Technology

[0002] The pipe flaring machine is a high-efficiency pipe internal diameter expansion device. It uses hydraulic or mechanical drive to push the flaring head to precisely expand the pipe diameter. The device consists of a frame, conveyor, guide, and flaring tool, offering advantages such as precise diameter expansion, high efficiency and stability, wide applicability, and pipe protection. Currently, most pipe flaring devices used on construction sites involve on-site flaring operations followed by pipe sleeve connection. During flaring, the operator inserts the end of the metal pipe into the flaring end of the machine, then uses the machine to expand the inside of the pipe end. However, a problem exists: the operator needs to align the metal pipe when holding it in the flaring position, which reduces the number of pipes that can be flared per unit time, thus decreasing the ease of use of the flaring machine. Utility Model Content

[0003] Based on this, the purpose of this utility model is to provide a building metal sleeve flaring device to solve the technical problems of poor guidance of pipe fittings by traditional on-site flaring machines, pipe fitting misalignment during the flaring process, and reduced ease of operation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a building metal sleeve flaring device, including an operating table, a mounting plate fixedly installed on one side of the top of the operating table, and multiple flaring machines equidistantly installed on one side of the mounting plate, and multiple guide mechanisms provided on the other side of the top of the operating table, which are one-to-one opposite to the multiple flaring machines, the guide mechanism including a mounting block, the surface of the mounting block having a groove, a plurality of guide rods being provided through the mounting block, and an adjusting handwheel being rotatably connected to the bottom surface of the mounting block through a thrust bearing, and the adjusting handwheel being threadedly connected to the operating table.

[0005] By adopting the above technical solution, it is ensured that the pipe fitting can slide steadily and smoothly in the groove. Then, the operator can easily move the pipe fitting along the predetermined trajectory in the groove by simply turning it. Since the pipe fitting supported by the groove and the flaring end of the flaring machine are precisely set to be coaxial, the pipe fitting can naturally align and fit with the flaring end during the sliding process, thus completely eliminating the cumbersome and time-consuming alignment operation in the traditional flaring operation.

[0006] Furthermore, the inner side of the groove has an arc-shaped structure, and the pre-processed pipe fitting carried by the groove is arranged coaxially with the flaring machine.

[0007] By adopting the above technical solution, the pipe fittings can be placed stably and naturally in the groove, which not only enhances the stability of the pipe fittings in the groove, but also ensures the positioning accuracy of the pipe fittings during the flaring process, avoiding problems such as poor flaring quality or pipe fitting damage caused by positional deviation.

[0008] Furthermore, the groove has an open structure on both sides, and several balls are provided on the inner sidewalls of both sides, arranged linearly at equal intervals, for rolling friction support of the processed sleeve.

[0009] By adopting the above technical solution, operators can easily put or take out the processing sleeve into the groove, which greatly improves the convenience of operation. The open structure also provides sufficient space for the processing sleeve to move in the groove, ensuring the freedom of the sleeve during the flaring process.

[0010] Furthermore, the mounting block has a rectangular block structure, and four sets of guide rods are provided, distributed at the four corners of the mounting block.

[0011] By adopting the above technical solution, the mounting block has a stable support surface and good mechanical properties. The rectangular block structure also facilitates installation and positioning, ensuring the stability and reliability of the mounting block in the equipment.

[0012] Furthermore, the flaring machine includes a hydraulic cylinder, and one side of the hydraulic cylinder is connected to several blades via a flange, the blades being arranged in an equidistant ring.

[0013] By adopting the above technical solution, the hydraulic cylinder provides a powerful power source and realizes the flaring operation through hydraulic transmission. One side of the hydraulic cylinder is connected by a flange. This connection method not only ensures a stable connection between the hydraulic cylinder and subsequent components, but also facilitates disassembly and maintenance, thus improving the maintainability of the equipment.

[0014] Furthermore, the blades have flared ends, a contraction ring is fitted on the outer side of several blades, an expansion block is provided at the central axis of several blades, and the expansion block is fixedly connected to the telescopic end of the hydraulic cylinder, and the expansion block has a conical structure.

[0015] By adopting the above technical solution, the blade can directly flare the processed sleeve under the pull of the hydraulic cylinder without the need for additional tools or devices, thereby simplifying the flaring process and improving work efficiency. The shape and size of the flared end can be customized according to actual needs to meet the flaring requirements of different specifications of sleeves.

[0016] In summary, the present invention has the following main advantages:

[0017] 1. This utility model uses a guiding mechanism. The operator places the pipe fitting into the groove and then gently moves it to slide within the groove. Due to the precise design of the groove, its inner side has an arc-shaped structure that fits tightly against the shape of the pipe fitting. Furthermore, the pipe fitting supported by the groove is coaxial with the flaring machine. This feature ensures that the pipe fitting can naturally and accurately align with the flaring end during the sliding process, thus eliminating the cumbersome alignment operation in the traditional flaring process. At the same time, it greatly improves the convenience of pipe flaring operation. The operator does not need to spend a lot of time and energy adjusting the position of the pipe fitting; a simple flick is all it takes to achieve quick alignment. This not only simplifies the operation process but also significantly improves work efficiency, resulting in a significant increase in the number of pipe fittings processed per unit time.

[0018] 2. This utility model, by setting an adjusting handwheel and a guide rod, allows for easy lifting of the mounting block by turning the adjusting handwheel. The threaded connection between the adjusting handwheel and the operating table plays a crucial guiding role during the lifting process. The guide rod ensures that the mounting block maintains a stable movement trajectory during lifting, avoiding operational errors caused by offset or tilt. This allows for precise coaxial adjustment of the central axis of the pre-processed pipe fitting with the flared end, thereby ensuring the accuracy and quality of the flaring operation. This function greatly improves the environmental applicability of the flaring device, enabling it to easily meet the processing needs of pipe fittings of various specifications and sizes.

[0027] The embodiments of this utility model will be described below based on its overall structure.

[0028] Example 1:

[0029] A flaring device for building metal sleeves, such as Figures 1-4As shown, the system includes an operating table 1. A mounting plate 2 is fixedly installed on one side of the top of the operating table 1, and multiple flaring machines 3 are equidistantly mounted on one side of the mounting plate 2. Multiple guide mechanisms 4 are installed on the other side of the top of the operating table 1, and are positioned opposite each of the multiple flaring machines 3. Each guide mechanism 4 includes a mounting block 401. A groove 402 is formed on the surface of the mounting block 401, and several guide rods 403 are inserted through the mounting block 401. An adjusting handwheel 404 is rotatably connected to the bottom surface of the mounting block 401 through a thrust bearing 405, and the adjusting handwheel 404 is threadedly connected to the operating table 1, ensuring that the pipe fittings can slide steadily and smoothly within the groove 402. Subsequently, the operator makes the pipe move along a predetermined trajectory within the groove 402 by simply turning it. Since the pipe supported by the groove 402 and the flaring end 304 of the flaring machine 3 are precisely set to be coaxial, the pipe can naturally align and engage with the flaring end 304 during the sliding process. This completely eliminates the tedious and time-consuming alignment operation in traditional flaring operations. At the same time, this coaxial setting not only greatly improves the convenience of pipe flaring operations, but also significantly improves work efficiency. The operator no longer needs to spend extra time and effort to precisely adjust the position of the pipe; a simple turn is all it takes to achieve a quick and accurate engagement.

[0030] See Figure 1 , Figure 2 , Figure 4 The inner side of the groove 402 has an arc-shaped structure, and the pre-processed pipe fitting carried by the groove 402 is set coaxially with the flaring machine 3. This allows the pipe fitting to be placed stably and naturally in the groove 402, which not only enhances the stability of the pipe fitting in the groove 402, but also ensures the positioning accuracy of the pipe fitting during the flaring process. This avoids problems such as poor flaring quality or pipe fitting damage caused by positional deviation. At the same time, the pre-processed pipe fitting carried by the groove 402 and the flaring machine 3 are precisely set coaxially. This setting greatly simplifies the alignment process between the pipe fitting and the flaring machine. The operator does not need to make tedious adjustments. He only needs to put the pipe fitting into the groove 402 and gently move it to achieve a quick and accurate connection between the end of the pipe fitting and the flaring end 304 of the flaring machine.

[0031] See Figure 1 , Figure 2 , Figure 4The groove 402 has an open structure on both sides, and several ball bearings 406 are arranged linearly at equal intervals on the inner walls of both sides for rolling friction support of the processing sleeve. This allows the operator to easily put the processing sleeve into or take out the groove 402, greatly improving the convenience of operation. The open structure also provides sufficient space for the movement of the processing sleeve in the groove 402, ensuring the freedom of the sleeve during the flaring process. At the same time, the ball bearings 406 on the inner walls of both sides of the groove 402 utilize the rolling characteristics of the ball bearings 406 to provide rolling friction support for the movement of the processing sleeve in the groove 402. Compared with traditional sliding friction, rolling friction has lower frictional resistance and better motion stability. This not only reduces the resistance when the sleeve moves, but also reduces wear and energy consumption.

[0032] Example 2:

[0033] See Figure 1 , Figure 2 , Figure 4 The mounting block 401 has a rectangular block structure, and four sets of guide rods 403 are provided and distributed at the four corners of the mounting block 401. This gives the mounting block 401 a stable support surface and good mechanical properties. The rectangular block structure also facilitates installation and positioning, ensuring the stability and reliability of the mounting block 401 in the equipment. At the same time, the four sets of guide rods 403 are cleverly distributed at the four corners of the mounting block 401. This layout not only enhances the structural stability of the mounting block 401, but also achieves precise guidance and positioning of the mounting block 401 through the synergistic effect of the four sets of guide rods 403.

[0034] See Figure 1 , Figure 2 , Figure 3 The flaring machine 3 includes a hydraulic cylinder 301. One side of the hydraulic cylinder 301 is connected to several blades 303 via a flange 302. The blades 303 are arranged in an equidistant ring. The hydraulic cylinder 301 provides a powerful power source and realizes the flaring operation through hydraulic transmission. The connection of the hydraulic cylinder via the flange 302 not only ensures a stable connection between the hydraulic cylinder and subsequent components, but also facilitates disassembly and maintenance, improving the maintainability of the equipment. At the same time, the connection of the hydraulic cylinder 301 with several blades 303 via the flange 302 allows the blades to act evenly on the inner wall of the processed sleeve during the flaring process, avoiding uneven flaring or sleeve deformation caused by uneven force.

[0035] See Figure 1 , Figure 2 , Figure 3The blade 303 has a flared end 304 at its end. A shrinkage ring 305 is fitted on the outer side of several blades 303. An expansion block 306 is provided at the central axis of several blades 303, and the expansion block 306 is fixedly connected to the telescopic end of the hydraulic cylinder 301. The expansion block 306 has a conical structure, which allows the blades to directly flare the processed sleeve under the pull of the hydraulic cylinder 301 without the need for additional tools or devices, thereby simplifying the flaring process and improving work efficiency. The shape and size of the flared end 304 can be customized according to actual needs to meet the flaring requirements of different specifications of sleeves. At the same time, the shrinkage ring 305 is fitted on the outer side of several blades 303. The elasticity of the shrinkage ring allows the blades to quickly retract to their original position after the flaring operation is completed, preparing for the next flaring operation.

[0036] The implementation principle of this utility model is as follows: When it is necessary to flare the end of the sleeve, firstly, the operator places the pipe inside the groove 402, and then moves the pipe to slide inside the groove 402. Since the pipe supported by the groove 402 is coaxially arranged with the flaring machine 3, the end of the pipe can be quickly sleeved on the flared end 304, thereby eliminating the need for the pipe to be aligned with the flared end 304, improving the convenience of the flaring operation of the pipe, and increasing the number of pipes processed per unit time.

[0037] This application provides multiple flaring machines 3 for expanding flaring shapes with different inner diameters, thereby improving the environmental adaptability of the flaring device, and is equipped with corresponding guiding mechanisms 4 to ensure that each flaring machine 3 has a guiding function for the pipe fitting.

[0038] First, by turning the adjusting handwheel 404, the mounting block 401 is lifted by the threaded connection between the adjusting handwheel 404 and the operating table 1. With the guidance of the guide rod, the mounting block 401 can be moved longitudinally. This allows the central axis of the pre-processed pipe fitting to be coaxially adjusted with the flared end 304 when processing pipe fittings of different diameters, thereby further improving the environmental applicability of the flaring device.

[0039] All parts not covered in this utility model are the same as or can be implemented using existing technologies, and will not be described in detail here.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
