Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of pipe bending tools, and in particular relates to a pipe bender with a digital display function. Background Art
[0002] During on-site construction, pipes need to be bent, which is usually done manually. However, manual bending has low process precision and is prone to deviations, making it difficult for the pipe's bending radius to meet regulatory requirements, which in turn affects the pipe's appearance quality and may even shorten its service life. In addition, manual pipe bending usually requires a longer operating length, usually not less than 200 mm. When connected to equipment such as radiators, excess parts are often produced, which need to be cut off. The short pipes after cutting are often unable to be reused, resulting in a serious waste of materials. Although there are pipe benders on the market, due to their structural limitations, there are many shortcomings and deficiencies in their use.
[0003] First, due to design limitations, existing pipe benders often lack flexibility and versatility, making them difficult to handle complex bending requirements. This is particularly true when performing bends at multiple angles or along complex curves, where precise control is limited, resulting in limited operational effectiveness. Second, most pipe benders lack digital displays, preventing operators from monitoring and adjusting the bending angle in real time. This can easily lead to inconsistent bending angles, impacting the pipe's appearance, quality, and service life. Furthermore, manual bending processes can have significant deviations, making it difficult for pipe bend radiuses to meet regulatory requirements, further impacting construction quality. Manual bending also requires a long operating length, often resulting in excess material that needs to be cut off. These cut short pipes are often unusable, resulting in material waste. Although existing pipe benders are commercially available, these limitations not only make their use time-consuming and labor-intensive, but can also easily cause pipe deformation or blockage, reducing efficiency and increasing repair and replacement costs. In summary, existing pipe benders still have numerous shortcomings in terms of functionality, efficiency, and material utilization, urgently requiring improvement and innovation.

This feature makes bending operations more intuitive, significantly reducing operational deviations caused by angle measurement errors, and thus ensuring accuracy and consistency in the bending process.
[0016] Secondly, this digital display significantly improves work efficiency. Traditional pipe bending operations often require frequent interruptions to measure angles, which is not only time-consuming and labor-intensive, but also prone to repeated operations due to inaccurate measurements. However, the new pipe bender's built-in digital display allows operators to monitor angles instantly while bending the pipe, without interrupting the operation, thus speeding up the construction process. As a result, construction workers can complete more tasks in a shorter time, significantly improving overall construction efficiency.
[0017] Furthermore, the new pipe bender design significantly simplifies pipe connection operations. Precisely controlled bend angles allow for smoother pipe connections, reducing installation difficulties and rework caused by improper angles. This not only improves the overall aesthetics of the piping system and the security of connections, but also reduces operational complexity, enabling construction workers to complete their tasks with greater ease and less physical and mental strain.
[0018] Furthermore, this digital tube bender significantly reduces construction costs by minimizing operational errors and the need for rework. Precise bending reduces material waste and construction errors, saving the additional costs associated with waste and rework. This cost savings is particularly significant for large-scale projects, further improving the economic efficiency of the project.
[0019] In summary, pipe benders with digital displays not only improve operational accuracy and consistency through precise angle control, but also reduce construction costs by streamlining operational processes and minimizing rework, significantly improving overall work efficiency and quality. This new tool provides an efficient and convenient solution for modern pipeline construction and maintenance, making it an ideal assistant for construction workers in their daily work.

[0021] Figure 2 This is a state diagram of the pipe bender of the utility model after bending the pipe; DETAILED DESCRIPTION
[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0023] To address the issues of existing pipe benders lacking an operational data display function, resulting in difficulty in quality control and poor quality control of finished products, this utility model provides a pipe bender with a digital display function. This pipe bender achieves precise pipe bending through the digital display function, simplifies the operation process, reduces material waste, and significantly improves work efficiency and construction quality. To further illustrate the structure of this utility model, a detailed description is provided in conjunction with the accompanying drawings as follows:
[0024] See also Figure 1 and Figure 2 A pipe bender with a digital display includes a fixed support block 1, a movable push block 2, and a push rod mechanism that drives the movable push block. The push rod body 11 of the push rod mechanism drives the movable push block axially, which applies bending stress to the pipe supported by the fixed support block. The fixed support block and the movable push block together form the three fulcrums required for pipe bending. The movable push block forms the active fulcrum, and the bending stress is applied to the pipe by changing the position of the fulcrum.
[0025] Specifically, the push rod mechanism includes a push rod seat 3, a bending handle 4, a rack 5, and a fixed pull plate 6. The bending handle is mounted to the push rod seat via a rotating shaft 7, and the rack is mounted to the push rod body. The inner end of the bending handle engages with the rack and drives the rack to move axially. The fixed pull plate is fixed to the front of the push rod seat, and the fixed support block is mounted to the fixed pull plate. The push rod seat and the push rod body form an axial moving pair. In this embodiment, the rack and push rod body are integrally constructed, and the rack is formed by the tooth shape machined on the lower part of the push rod body.
[0026] In this embodiment, a guide groove is provided within the ejector seat. Its shape and dimensions match the cross-section of the ejector body, ensuring smooth axial movement of the ejector body within the seat. The ejector seat is bolted or welded to a fixed plate, which is connected to a fixed support block to ensure the stability of the entire pipe bender. This bolted connection allows the ejector seat to be adjusted relative to the fixed plate, adjusting the position and angle of the structure to suit different pipe bending requirements.
[0027] In this embodiment, two fixed support blocks are installed symmetrically on the left and right sides of the fixed pull plate, and the movable top block is installed at the front end of the push rod body, and the movable top block is located between the two fixed support blocks. The fixed support block is installed on the fixed pull plate via a support shaft 8, and the axis of the support shaft is perpendicular to the moving plane of the movable top block. The fixed support block can rotate freely around the support shaft to ensure that the tube body is supported at an angle corresponding to the bending of the tube body after bending. A bend groove is provided on the side of the fixed support block, and a bend groove is provided at the front end of the movable top block. The front end face of the movable top block is an arc-shaped end face, and the arc-shaped end face of the movable top block is provided with an arc-shaped bend groove.
[0028] The pipe bending handle and the ejector base are hingedly connected via a rotating shaft, forming a scissor-like structure. One end of the handle meshes with a rack, while the other end is used by the operator to apply force. This scissor-like handle structure utilizes the principle of leverage, with the swing of the handle controlling the movement of the rack, which in turn drives the ejector body axially. In operation, the user repeatedly pushes and pulls the handle until the handle ends tightly engage the rack. Each time the handle is pushed down, the gear on the inner end of the handle meshes with the gear on the rack, pushing the rack forward axially along the ejector body. This process, through repeated manipulation of the handle, gradually applies force, gradually advancing the ejector body to the desired position. To retract the ejector body, the user pulls down on the other end of the pipe bending handle. This action disengages the handle from the rack, freeing the ejector body from the forward thrust. Since there is generally no resistance between the ejector body and the ejector base to prevent its free movement, the ejector body naturally retracts axially to its original position under the action of gravity. This structure is typical of conventional handle-type pipe benders.
[0029] The push rod seat is installed with a position information acquisition component, which acquires the axial position information of the push rod body. In this embodiment, the position information acquisition component is a digital ruler 9, which is also called a multifunctional measuring instrument. It is an existing component that can be purchased. The measuring end of the digital ruler corresponds to the push rod body and collects the axial movement position change information of the push rod body. The detection seat 10 is installed on the upper part of the push rod seat, and the digital ruler is fixed on the detection seat. The upper part of the push rod seat is provided with an opening, and the upper end face of the push rod body is exposed to the opening. The detection seat is installed at the position corresponding to the opening on the push rod seat. The measuring end of the digital ruler is a roller. After the digital ruler is mounted on the detection seat, the roller of the digital ruler rolls the upper end face of the push rod body. The axial extension and contraction process of the push rod drives the roller of the digital ruler to roll, thereby realizing data collection.
[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
