Description

Technical Field

[0001] This utility model relates to the field of pipe processing equipment technology, and in particular to a metal pipe bending device for building construction. Background Technology

[0002] In construction, bending metal pipes usually requires precise equipment to ensure smooth installation and use of the pipes. Traditional manual or inefficient pipe bending tools are often unable to meet the needs of large-scale construction and have problems such as large errors and low work efficiency. In order to improve construction efficiency and the quality of pipe bending, metal pipe bending equipment specifically designed for the construction industry has been developed.

[0003] However, in actual use, the following shortcomings still exist. For example, existing metal pipe bending equipment used in building construction cannot achieve pipe lubrication and friction prevention, precise bending, and ensure bending quality and processing efficiency. Lack of lubrication easily leads to increased friction between the pipe and equipment components, causing scratches and wear on the pipe surface. This not only affects the appearance but also weakens the structural strength of the pipe, making it prone to leakage and rupture problems in later use. Especially for fire protection and water supply and drainage pipelines, this may cause safety accidents and engineering hazards. The inability to bend precisely results in large deviations in pipe angle and curvature, which do not meet construction specifications. This requires reprocessing or replacement of pipes, significantly increasing material waste and construction costs. At the same time, frequent rework will delay the construction progress and reduce the overall processing efficiency. In addition, high friction and poor bending accuracy may also lead to increased equipment load, shorten the equipment's service life, increase maintenance frequency and costs, and further affect the quality, efficiency, and economy of building construction.

[0004] Therefore, this utility model proposes a metal pipe bending device for building construction to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and to propose a metal pipe bending device for building construction.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a metal pipe bending device for building construction, comprising a base plate, and further comprising:

[0007] A pipe bending assembly includes a first support base connected to a base plate, a first bending wheel disposed on the first support base, a second bending wheel disposed on the side of the first support base near the first bending wheel, a guide block disposed on the side of the first support base near the second bending wheel, a first servo motor mounted on the bottom of the base plate, and a pipe bending arm connected to the output end of the first servo motor.

[0008] A pipe surface treatment assembly includes a second support base connected to a base plate near the material guide block. A bracket is connected to the second support base. A limiting ring is installed on the bracket. An inlet is provided on the limiting ring near the top. A roller is provided inside the limiting ring. An outlet is provided on the limiting ring near the bottom.

[0009] Furthermore, a pushing component is provided on the side of the base plate away from the bending assembly. The pushing component includes a support frame connected to the base plate, on which a second servo motor is mounted. The output end of the second servo motor is connected to a first transmission wheel.

[0010] The beneficial effects of adopting the above-mentioned further solution are: the push component on the side of the base plate away from the bending pipe assembly provides an installation foundation for the whole. After the second servo motor starts, it transmits power to the first transmission wheel connected to the output end, driving the first transmission wheel to rotate, providing initial power for the subsequent pipe pushing transmission link, and is the power source of the pushing action.

[0011] Furthermore, a belt is provided on the first transmission wheel, and a second transmission wheel is provided on the belt. Both the first transmission wheel and the second transmission wheel are rotatably connected to the support frame.

[0012] The beneficial effects of adopting the above-mentioned further solution are: when the first transmission wheel rotates, it drives the second transmission wheel to rotate synchronously through the belt on it. Since both are rotatably connected to the support frame, the transmission state can be stably maintained. The belt serves as the transmission medium to realize the transmission of power from the first transmission wheel to the second transmission wheel, thus constructing the transmission system of the pushing component and storing power for the movement of the pushing seat.

[0013] Furthermore, a push seat is provided on the support frame, and a limit seat is connected to the side of the support frame near the push seat. The push seat is slidably connected to the limit seat and connected to the belt.

[0014] The beneficial effects of adopting the above-mentioned further solution are: the limiting seat on the support frame plays a guiding and limiting role for the push seat. When the belt rotates, the push seat connected to it slides in a straight line under the constraint of the limiting seat, avoiding the push seat from deviating and ensuring that it can stably drive the movement of subsequent components, providing a stable linear motion trajectory for the pipe push.

[0015] Furthermore, a fixing block is connected to the top of the pusher seat, a clamping block is slidably connected inside the fixing block, and a limit groove is formed on the top of the fixing block.

[0016] The beneficial effects of adopting the above-mentioned further solution are: the fixing block at the top of the push seat is the basic component for clamping the pipe. The clamping block can slide within the fixing block so as to adjust the clamping distance according to the pipe size. The limiting groove at the top of the fixing block provides space for the subsequent movement and limiting of the screw, ensuring the smoothness of the clamping and adjustment process.

[0017] Furthermore, a screw is connected to the top of the clamping block, the screw is slidably connected in the limiting groove, and a nut is threaded onto the screw.

[0018] The beneficial effects of adopting the above-mentioned further solution are: the screw at the top of the clamping block can slide along the limiting groove, thereby driving the clamping block to adjust its position. When the screw slides to the appropriate position, the nut on it is turned, and the nut and the screw thread engage to generate clamping force, thereby fixing the clamping block and achieving stable clamping of pipes of different specifications.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] In this invention, the metal pipe bending equipment first undergoes pretreatment by a pipe surface treatment component. The pipe then passes through the limiting ring of the second support bracket, and a special lubricant is injected into the inlet. Rollers inside the limiting ring assist the pipe's movement, ensuring that the lubricant evenly covers the inner and outer walls of the pipe. Excess lubricant is discharged from the outlet, reducing friction during subsequent bending. The pretreated pipe is guided by a guide block and enters the bending assembly. The first and second bending wheels on the first support bracket clamp the pipe. The first servo motor at the bottom of the base plate starts, driving the bending arm to rotate. The bending arm causes the pipe to rotate around the first bending wheel. Under the limiting and clamping of the two bending wheels, the pipe bends along a preset trajectory, ultimately forming a bent pipe product that meets the requirements. This achieves pipe lubrication and friction prevention, precise bending, and ensures bending quality and processing efficiency. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figures 1-3 As shown, this embodiment provides a technical solution: a metal pipe bending device for building construction, including a base plate 1, and further comprising:

[0033] The pipe bending assembly 2 includes a first support base 21 connected to the base plate 1, a first bending wheel 22 is provided on the first support base 21, a second bending wheel 23 is provided on the side of the first support base 21 near the first bending wheel 22, a guide block 24 is provided on the side of the first support base 21 near the second bending wheel 23, a first servo motor 25 is installed at the bottom of the base plate 1, and the output end of the first servo motor 25 is connected to the bending arm 26.

[0034] The pipe surface treatment component 3 includes a second support base 31 connected to the base plate 1 near the guide block 24. A bracket 32 ​​is connected to the second support base 31, and a limit ring 33 is installed on the bracket 32. An inlet 34 is located on the top side of the limit ring 33, a roller 35 is installed inside the limit ring 33, and an outlet 36 is located on the bottom side of the limit ring 33. When the metal pipe bending equipment is working, the pipe surface treatment component 3 performs pretreatment. The pipe then passes through the limit ring 33 of the bracket 32 ​​of the second support base 31. A special lubricant is injected through the inlet 34, and the roller 35 inside the limit ring 33 assists in the process. The lubricant is evenly distributed on the inner and outer walls of the pipe by the guide block 24, and excess lubricant is discharged from the outlet 36 to reduce friction during subsequent pipe bending. The pre-treated pipe is guided by the guide block 24 and enters the pipe bending assembly 2. The first bending wheel 22 and the second bending wheel 23 on the first support 21 cooperate to clamp the pipe. The first servo motor 25 at the bottom of the base plate 1 is started to drive the bending arm 26 to rotate. The bending arm 26 drives the pipe to rotate around the first bending wheel 22. Under the limit and clamping of the two bending wheels, the pipe is bent according to the preset trajectory, and finally forms a bent pipe product that meets the requirements. This achieves pipe lubrication and anti-friction, precise bending, and ensures the quality and processing efficiency of pipe bending.

[0035] The above solutions also have the problem of not being able to stably clamp and push pipes of different specifications when performing metal pipe bending operations, such as... Figure 1 as well as Figures 4-5As shown: A pushing component 4 is provided on the side of the base plate 1 away from the pipe bending assembly 2. The pushing component 4 includes a support frame 41 connected to the base plate 1. A second servo motor 42 is mounted on the support frame 41. The output end of the second servo motor 42 is connected to a first transmission wheel 43. The support frame 41 of the pushing component 4 on the side of the base plate 1 away from the pipe bending assembly 2 provides the installation foundation for the whole. After the second servo motor 42 starts, it transmits power to the first transmission wheel 43 connected to the output end, driving the first transmission wheel 43 to rotate. This provides the initial power for the subsequent pipe pushing transmission link and is the power source of the pushing action. A belt 44 is provided on the first transmission wheel 43. A second transmission wheel 45 is provided on the support frame 44. Both the first transmission wheel 43 and the second transmission wheel 45 are rotatably connected to the support frame 41. When the first transmission wheel 43 rotates, it drives the second transmission wheel 45 to rotate synchronously through the belt 44 on it. Since both are rotatably connected to the support frame 41, the transmission state can be stably maintained. The belt 44 serves as the transmission medium to realize the transmission of power from the first transmission wheel 43 to the second transmission wheel 45, thus constructing the transmission system of the pushing component 4 and storing power for the movement of the pushing seat 46. The support frame 41 is provided with a pushing seat 46. A limit seat 47 is connected to the side of the support frame 41 near the pushing seat 46. The pushing seat 46 is slidably connected to the limit seat 47. On seat 47, push seat 46 is connected to belt 44. Limit seat 47 on support frame 41 guides and limits push seat 46. When belt 44 rotates, push seat 46, connected to it, slides linearly under the constraint of limit seat 47, preventing push seat 46 from deviating and ensuring it can stably drive subsequent components, providing a stable linear motion trajectory for pipe pushing. A fixing block 48 is connected to the top of push seat 46, and a clamping block 49 is slidably connected within the fixing block 48. A limit groove 410 is provided on the top of the fixing block 48. The fixing block 48 at the top of push seat 46 is the basic component for clamping the pipe. The clamping block 49 can slide within the fixing block 48 to facilitate... The clamping spacing is adjusted according to the pipe size. The limiting groove 410 on the top of the fixing block 48 provides space for the subsequent movement and limiting of the screw 411, ensuring smooth clamping and adjustment. The top of the clamping block 49 is connected to the screw 411, which is slidably connected in the limiting groove 410. The screw 411 is threaded with a nut 412. The screw 411 on the top of the clamping block 49 can slide along the limiting groove 410, driving the clamping block 49 to adjust its position. When the screw 411 slides to the appropriate position, the nut 412 on it is turned. The nut 412 and the screw 411 are threaded together to generate clamping force, fixing the clamping block 49, thereby achieving stable clamping of pipes of different specifications.

[0036] Working principle:

[0037] like Figures 1-5As shown, before pipe processing, the clamping structure of the pushing component 4 is adjusted according to the specifications and dimensions of the pipe to be processed. The clamping block 49 inside the sliding fixing block 48 slides, and the screw 411 on the top of the clamping block 49 slides synchronously along the limiting groove 410. After the spacing is appropriate, the nut 412 is screwed into the screw 411 to fix the clamping block 49, thus completing the clamping and fixing of the pipe. The second servo motor 42 is started, and the power is transmitted to the first transmission wheel 43. The second transmission wheel 45 is driven to rotate synchronously through the belt 44. The pushing seat 46 connected to the belt 44 slides stably along a straight line under the guidance and limitation of the limiting seat 47, thereby driving the pipe clamped by the fixing block 48 and the clamping block 49 to be transported towards the bending component 2. During the pipe transport process, it first enters the pipe surface treatment component 3. The pipe passes through the limiting ring 33 of the bracket 32 ​​on the second support seat 31. The liquid inlet 34 continuously injects special lubricant. The rollers 35 inside the limiting ring 33 assist the smooth movement of the pipe and simultaneously ensure that the lubricant evenly covers the inner and outer walls of the pipe. Excess lubricant is discharged from the outlet 36, effectively reducing friction loss during subsequent pipe bending. After pretreatment, the pipe is continuously pushed by the pushing component 4 and precisely guided by the guide block 24 into the pipe bending component 2. The first bending wheel 22 and the second bending wheel 23 on the first support 21 cooperate to stably clamp and limit the pipe, ensuring that the pipe does not deviate during bending. At this time, the first servo motor 25 at the bottom of the base plate 1 starts, driving the bending arm 26 to rotate along the preset trajectory. The bending arm 26 drives the pipe to rotate around the first bending wheel 22. Under the dual constraint and clamping action of the two bending wheels, the pipe gradually bends along the preset trajectory, finally forming a bent pipe product that meets the specifications, achieving efficient and high-quality pipe bending processing.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
