It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0021] Concave strip components are frequently used in the design of industrial equipment. Their internal grooves provide a high strength-to-weight ratio during bending and torsion. In industrial equipment where weight reduction and stability are crucial, concave strip components can conceal electrical wires, cables, hydraulic lines, and pneumatic lines, resulting in a clean, safe appearance and protecting the wiring within the grooves from damage.

[0022] In practical applications, the chuck can grip the two side walls of a concave elongated component and push them open in the opposite direction to achieve the purpose of flaring. However, in some flaring scenarios, it is necessary to add corresponding materials at the flaring position of the groove wall or to seal the groove. In this case, the added materials conflict with the gripping position of the chuck, making it impossible to simultaneously perform the flaring from the outside of the groove and the installation of the concave elongated component.

[0023] This utility model provides a flaring device that can perform flaring operations from inside a concave elongated component, ensuring the exposure of the flaring position on the groove wall and facilitating further processing and fitting of the flaring position.

[0024] like Figure 1 As shown, the flaring device provided in this embodiment includes a tooling body 1, and a slide groove 101 is provided on the tooling body 1 along a first direction. A limiting hole 102 is provided on the side of the slide groove 101, and a guide post 103 is slidably disposed in the limiting hole 102. A slider 2 is slidably disposed in the slide groove 101. The slider 2 includes a wedge-shaped portion 21, which is disposed on the side of the slider 2, and the side of the slider 2 is opposite to the side of the slide groove 101. The wedge-shaped portion 21 is used to abut against the guide post 103 and push the guide post 103 out along the limiting hole 102; the wedge-shaped portion 21 abuts against the guide post 103, and along the first direction, the wedge-shaped portion 21 includes a bottom 211 and a top 212, and the distance between the wedge-shaped portion 21 and the side of the slide groove 101 gradually changes from the bottom 211 to the top 212.

[0025] In this embodiment, the external contour of the tooling body 1 can be selected with a corresponding shape and size based on the internal space shape and size of the concave elongated component. By utilizing the opening at the end face of the groove of the concave elongated component, pressure is applied to the tooling body 1 from the opening, thereby placing the tooling body 1 within the groove of the concave elongated component.

[0026] The tooling body 1 is provided with a slide groove 101, and the direction of the slide groove 101 is a first direction, which in this embodiment is the length direction of the concave elongated member. Along the first direction, a limiting hole 102 is provided on the side of the slide groove 101, and the limiting hole 102 penetrates the side of the slide groove 101 and the outer side of the tooling body 1. A guide post 103 is slidably disposed in the limiting hole 102, and the length of the guide post 103 is longer than the limiting hole 102. When one end of the guide post 103 is flush with the outer side of the tooling body 1, the other end protrudes out of the limiting hole 102 and is exposed in the slide groove 101. And when the end of the guide post 103 exposed in the slide groove 101 is subjected to pressure, the guide post 103 slides along the opening direction of the limiting hole 102 and protrudes out towards the outer side of the tooling body 1.

[0027] A slider 2 is slidably disposed within a groove 101, and the slider 2 slides within the groove 101 along a first direction. A wedge-shaped portion 21 is disposed on the side of the slider 2, opposite to the side of the groove 101. Along the first direction, the wedge-shaped portion 21 has a bottom 211 and a top 212. The distance between the top 212 and the side of the groove 101 is greater than that between the bottom 211 and the side of the groove 101, and the minimum distance between the bottom 211 and the side of the groove 101 is zero. A plane or curved surface is formed between the bottom 211 and the top 212. Along the first direction, the distance from each point in the formed plane or curved surface to the side of the groove 101 gradually changes, that is, at least part of the plane or curved surface and the side of the groove 101 have an angle between them.

[0028] The guide post 103 abuts against the plane or curved surface formed between the bottom 211 and the top 212. Because the guide post 103 is slidably disposed within the limiting hole 102, it can only slide along the opening direction of the limiting hole 102. When the slider 2 slides within the groove 101, if the distance between the wedge-shaped portion 21 and the side of the groove 101 gradually decreases, pressure is generated that causes the guide post 103 to slide towards the outer side of the tooling body 1, causing the guide post 103 to protrude from the outer side of the tooling body 1. This further causes the guide post 103 to press against the inner wall of the groove of the concave elongated member, thereby widening the concave elongated member within the groove.

[0029] In this embodiment, as Figure 2 As shown, multiple limiting holes 102 are provided, and along the first direction, each limiting hole 102 is spaced apart on the side of the slide groove 101. By providing evenly distributed limiting holes 102, the guide post 103 can uniformly compress the inner wall of the groove, ensuring that the flared shape of the concave elongated component is regular.

[0030] In this embodiment, as Figure 3As shown, the wedge-shaped portion 21 includes an inclined plane 213. Along a first direction, the inclined plane 213 connects to the bottom 211 and the top 212, respectively, and the angle between the inclined plane 213 and the side of the slide groove 101 is an acute angle. The distance between the connection point of the inclined plane 213 and the top 212 and the side of the slide groove 101 is a first distance. The distance between the connection point of the inclined plane 213 and the bottom and the side of the slide groove 101 is a second distance. The first distance is greater than the second distance, and the second distance is at its minimum of zero. The distance between the inclined plane 213 and the side of the slide groove 101 gradually decreases from the top 212 to the bottom 211.

[0031] With the inclined plane 213 abutting against the guide post 103, within a certain range, the sliding distance of the slider 2 is linearly positively correlated with the sliding distance of the guide post 103 within the limiting hole 102. Therefore, the flaring size of the concave elongated component can be effectively controlled. Moreover, precise control of the flaring ensures that the deformation of the concave elongated component is always within the elastic deformation range, avoiding plastic deformation of the concave elongated component.

[0032] In this embodiment, the inclined plane 213 is symmetrically arranged on both sides of the wedge-shaped part 21, and the limiting hole 102 is symmetrically arranged on both sides of the slide groove 101. Each pair of symmetrical limiting holes 102 corresponds to one wedge-shaped part 21.

[0033] By providing two symmetrical inclined planes 213 in the wedge-shaped portion 21, during the sliding process of the slider 2, the two symmetrical inclined planes 213 can apply pressure to the corresponding guide posts 103, so that the two guide posts 103 slide simultaneously along the corresponding limiting holes 102, and thus protrude from the two symmetrical outer surfaces of the tooling body 1. The guide posts 103 protruding from the outer surfaces of the tooling body 1 can squeeze the inner wall of the groove of the concave elongated component, realizing the application of the same pressure to the inner walls of the grooves on both sides simultaneously. When the inner wall of the groove is subjected to symmetrical pressure, the deformation state is more stable and the flaring shape is more uniform.

[0034] like Figure 4 As shown, in this embodiment, a guide bead 104 abuts against one end of the guide post 103 near the wedge-shaped portion 21, and the guide bead 104 also abuts against the inclined plane 213. Because the guide post 103 is limited by the limiting hole 102, and when the inclined plane 213 applies pressure to the guide post 103, the guide post 103 is subjected to shear stress along the first direction. When the shear stress is too large or subjected to shear stress for a long time, the guide post 103 is prone to deformation. By having the guide bead 104 abut against the guide post 103 and the inclined plane 213, the guide bead 104 converts the shear stress it receives into rolling between the guide bead 104 and the inclined plane 213, thereby extending the service life of the guide post 103. In addition, the guide bead 104 rolls into the limiting hole 102 to apply pressure to the guide post 103, reducing the required length of the guide post 103, thereby improving the bending strength of the guide post 103.

[0035] The slider 2 also includes a first limiting part 22 and a second limiting part 23, which are disposed on the same side of the slider 2 as the wedge-shaped part 21. The first limiting part 22 is used to limit the guide bead 104 in a first direction, and the second limiting part 23 is used to limit the guide bead 104 in a second direction.

[0036] In this embodiment, due to the ball bearing structure of the guide bead 104, in order to prevent the device from jamming due to the rolling of the guide bead 104, it is necessary to limit the guide bead 104. The first limiting part 22 is configured to extend from the top 212 to the side of the slide groove 101, and is used to prevent the guide bead 104 from rolling in the first direction when the slider 2 is not sliding, because there is an angle between the slide groove 101 and the horizontal plane.

[0037] The second limiting part 23 is disposed within an approximately triangular area plane enclosed by the inclined plane 213, the first limiting part 22, and the side of the slide groove 101. The second direction is the direction from the upper surface to the lower surface of the slider 2, and the second limiting part 23 has a certain depth along the second direction. The second limiting part 23 is provided to prevent the guide bead 104 from rolling along the second direction.

[0038] In this embodiment, the first limiting part 22 is connected to the top 212, and the first limiting part 22 is a first limiting plane, which is perpendicular to the horizontal plane. Compared with the curved surface or other shapes formed by extending from the top 212 to the side of the slide groove 101, the first limiting plane is easier to process and maintains a tangential contact with the guide bead 104, so it will not hinder the rolling of the guide bead 104.

[0039] In this embodiment, the second limiting part 23 is connected to the inclined plane 213 along the second direction. The second limiting part 23 is a second limiting plane, which is perpendicular to the inclined plane 213 and the first limiting plane. During the sliding process of the slider 2, there are no acute angles between the second limiting plane and the inclined plane 213 and the first limiting plane, so no slope that hinders the movement of the guide bead 104 is generated, reducing wear between the guide bead 104 and the slider 2. At the same time, it ensures that the center of the guide bead 104 is at the same height as the central axis of the limiting hole 102, preventing the center of the guide bead 104 from being misaligned with the central axis of the limiting hole 102 due to compression and rotation, thus preventing the slider 2 from jamming.

[0040] In this embodiment, as Figure 5 As shown, the slider 2 includes a first part and a second part along the second direction. The first part is slidably disposed in the slide groove 101 and contacts the two sides of the slide groove 101. The second part has a wedge-shaped part 21, a first limiting part 22 and a second limiting part 23 along the second direction.

[0041] The slider 2 is a one-piece molded part produced by die casting or CNC milling. Compared with the separate combined slider, the slider 2 in this embodiment has higher overall structural strength and can apply greater pressure to the guide post 103, thereby meeting the flaring requirements within a wider stress range. The one-piece molded wedge-shaped portion 21, the first limiting portion 22, and the second limiting portion 23 can also withstand the reaction force applied by the guide post 103 or the guide bead 104 without deformation, thus improving service life and operational stability.

[0042] In this embodiment, along the first direction, both ends of the slider 2 are splicing planes, which are perpendicular to the horizontal plane. Considering actual working conditions, the length of the concave strip component ranges from tens of millimeters to tens of meters depending on the application. When flaring a portion of a longer concave strip component, the length of a single slider 2 can only flare a portion of the concave strip component. By designing both ends of the slider 2 as splicing planes 24, adjacent sliders 2 can abut against each other through the splicing planes 24, achieving the internal flaring of longer concave strip components by combining multiple sliders 2 within the groove 101. External equipment applies pressure to the slider 2 along the first direction, with the pressure direction being horizontal. The splicing plane, designed to be perpendicular to the horizontal plane, can better withstand and transmit horizontal pressure.

[0043] In this embodiment, the tooling body 1 is disposed in the groove of the concave elongated member, and the guide post 103 abuts against the inner wall of the groove. The inner wall of the groove is a continuous plane along the first direction, and multiple guide posts 103 can be evenly distributed on the inner wall of the groove to ensure that uniform pressure is applied to the concave elongated member by the guide posts 103, thereby obtaining a more regular flared shape.

[0044] In this embodiment, the central axis of the limiting hole 102 is on a horizontal plane and perpendicular to the inner wall of the groove of the concave elongated member. When the guide post 103 slides out of the limiting hole 102 under pressure, the guide post 103 abuts against the inner wall of the groove perpendicularly. This reduces the contact stress between the guide post and the inner wall of the groove, preventing local deformation.

[0045] In another embodiment of this utility model, a flaring device is provided, including the flaring apparatus disclosed in any of the above embodiments. Therefore, this flaring device includes all the technical effects of the aforementioned flaring apparatus. Since the technical effects of the flaring apparatus have been described in detail above, they will not be repeated here.

[0046] The flaring device also includes a power unit and a positioning fixture. The positioning fixture positions the flaring device and specifically includes a fastening threaded hole and a positioning pin reamer hole on the outer surface of the main body 1. The fastening threaded hole is located at both ends of the outer surface of the main body 1. The positioning pin reamer hole is arranged adjacent to the fastening threaded hole to facilitate loosening the fastening bolts for repositioning if the positioning is inaccurate.

[0047] The power unit is located at one end of the fixture body 1 and can apply pressure to the splicing plane of the slider 2. The power unit can be a one-way cylinder, a hydraulic cylinder, a stepper motor, etc.

[0048] In this embodiment, the flaring equipment also includes an automated control device, which comprises a human-machine interface (HMI), a programmable logic controller (PLC), and sensors. The HMI performs functions such as model selection, data transmission, progress monitoring, work prompts, and counting. The PLC performs logical control of the actuator's movements. The sensors feed back the actuator's execution structure to the PLC and display the results on the HMI as needed. Logical control of the power components can be achieved through the HMI and PLC.

[0049] In this embodiment, the flaring device is equipped with a visual analysis device, which can monitor the installation process of the concave elongated component in real time and provide feedback on abnormal images.

[0050] In this embodiment, the flaring device includes a stress monitoring sensor installed at the bottom of the concave elongated component. This sensor can monitor stress changes at the bottom of the concave elongated component in real time, controlling the stress value within the allowable elastic modulus range. Based on the Wheatstone strain gauge principle, the strain gauge of the stress monitoring sensor measures changes in the output current value. The deformation of the concave elongated component is converted into a current value within a certain range, thereby achieving stress control.

[0051] The flaring device in this embodiment is used to flare the concave elongated component, apply adhesive to the flared area, and then attach transparent material. Because the transparent material and the concave component are interference-fitted and cannot be inserted normally, the concave component needs to be flared to achieve a certain opening.

[0052] The concave elongated component used in this embodiment is made of 6063 aluminum alloy profile. 6063 aluminum alloy is an Al-Mg-Si wrought aluminum alloy. It possesses excellent extrudability, moderate strength, excellent corrosion resistance, and surface treatment properties. After heat treatment, 6063 aluminum alloy has an elastic modulus of 68.9 GPa, a Poisson's ratio of 0.33, a tensile strength ≥205 MPa, a yield strength ≥170 MPa, and an elongation ≥7%. It exhibits excellent extrusion molding properties and supports quenching methods such as air quenching and water quenching, with a wide quenching temperature range (520°C solution treatment). It exhibits strong material stability and shows no stress corrosion cracking when used in harsh environments such as humid heat and salt spray.

[0053] In another optional embodiment of this utility model, a method for using the flaring device is provided.

[0054] Step 1: Insert the main body 1 of the tooling into the groove openings at both ends of the concave long strip component. The number of sliders 2 set in the slide groove 101 is determined according to the length of the concave long strip component, and the splicing is completed.

[0055] Step 2: Fix the main body 1 of the tooling with the positioning fixture, and apply pressure to the slider 2 with the power component.

[0056] Step 3: Apply glue to the areas of the concave strip component that require it. Monitor the glue level in real time using visual analysis equipment and provide feedback on any abnormal glue application.

[0057] Step 4: Expand the concave strip component to the required opening degree, while monitoring the internal stress changes of the component in real time.

[0058] Step 5: Apply transparent material.

[0059] Step 6: Turn off the power unit, remove the concave strip component, and complete the flaring and mounting operation.

[0060] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0061] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0062] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
