Abstract

The present invention relates to a fitting bending device having a jam prevention function, and more particularly, to a fitting bending device having a jam prevention function, which can prevent the fitting bending device from being jammed between protruding portions of a fitting after bending by adjusting a fixing state and a separation state of the fitting when the fitting is bent if the length of the fitting is below a predetermined length.

Description

Technical Field

[0001] The present invention relates to a component bending device with anti-jamming function, and more specifically, to a component bending device with anti-jamming function with the following structure: when bending a component, if the length of the component is less than a specified length, the component bending device can be prevented from getting stuck between the protrusions of the component after bending by adjusting the fixed state and the separated state of the component. Background Technology

[0002] High-pressure fittings connect to pipes / high-pressure hoses used for transferring high-pressure fluids. The direction of the pipe is changed by bending (folding) at a specified angle. Various specifications / sizes / sized products can be used depending on their application.

[0003] In order to transfer high-pressure fluid, the aforementioned high-pressure fittings are made of specified metal materials and can be bent using bending devices to bend pipes of specified strength.

[0004] When existing component bending devices bend components of shorter length, the component placement part of the bending device often gets stuck between the protrusion and threaded part of the component. After the bending work is completed, it is often difficult or impossible to separate the component from the bending device.

[0005] Even when parts can be separated from the bending device, not only is there a time loss due to the inability to quickly separate the parts during the process, but the parts may also be deformed or damaged during the process of forcibly separating them by external force.

[0006] On the other hand, when components cannot be separated from the bending device, the manufacturing process itself must be altered. The ends (protrusions) and bent portions of the components must be manufactured separately, and then joined together through processes such as welding. In this case, due to issues with order delivery time and manufacturing costs, not only does the unit price of the product increase, but improper welding can also lead to fatal problems such as oil leaks. Therefore, to prevent such problems, a separate precision testing process is required. Summary of the Invention

[0007] Technical issues

[0008] The purpose of this invention is to improve upon the existing problems of the above-mentioned accessory bending devices by providing an accessory bending device with an anti-jamming function, wherein after bending the accessory, the fixed / separated state of the accessory can be adjusted in a desired manner to easily remove the accessory from the device.

[0009] Technical solution

[0010] To address the existing problems of the aforementioned component bending devices, the present invention provides a component bending device with anti-jamming function for bending components to achieve a predetermined angle between the inlet and outlet, and for disassembling the bent component. The device includes: a component placement section having a groove with a predetermined curvature, the groove being formed in a predetermined arc shape, such that the outer peripheral surface of the component is placed there; a separation section disposed on one side of the component placement section, having predetermined fixing and separation structures, fixed during the component bending process, and after the component bending process, moved to a position separated from the groove of the component placement section to provide space for disassembling the bent component; a transfer shaft providing a path for transferring the separation section, disposed in a direction perpendicular to a plane including the arc forming the groove of the component placement section; and an adjusting clamp disposed on the upper part of the transfer shaft for adjusting the transition between the fixed and separated states of the separation section. During the component bending process, the end of the component is fixed, preventing movement even when an external load is applied, and after the component bending process, the fixing of the end of the component can be released.

[0011] Furthermore, the aforementioned separation portion includes: a placement extension portion having an extension groove forming part of the groove of the aforementioned accessory placement portion; and an independent groove structure, which is separately disposed from the groove of the aforementioned accessory placement portion on the upper part of the placement extension portion as an independent component, and has a groove corresponding to the extension groove when in close contact with the aforementioned placement extension portion. The aforementioned transfer shaft may include: a support shaft fixed to one side of the aforementioned placement extension portion; a spring connected to the aforementioned support shaft to apply an upward elastic force to the independent groove structure; and a hook for preventing the aforementioned independent groove structure from detaching from the transfer shaft.

[0012] Furthermore, the aforementioned adjustment fixture includes: an adjustment body 4, disposed at the upper end of the aforementioned accessory placement portion, fixed by a predetermined hinge, forming a predetermined elongated shape capable of rotating around the aforementioned hinge; a hook rail formed on the bottom surface of the adjustment body 4, ensuring that the hook and the adjustment body 4 do not interfere with each other when the aforementioned adjustment body 4 rotates; and a rod connected to one side of the aforementioned adjustment body 4 for receiving predetermined power to rotate the adjustment body 4. The aforementioned separation portion includes: a handle fixed to the aforementioned independent slot structure, extending in a direction parallel to the transfer shaft; and a hook through hole formed in the independent slot structure. The structure prevents the independent slot structure from detaching from the transfer shaft via the hook; and the guide hole performs a predetermined guiding function when the independent slot structure moves in the vertical direction so that the independent slot structure cannot wobble in any direction other than the axial direction of the transfer shaft. An inner diameter smaller than the inner diameter of the hook through hole is formed at the lower part of the hook through hole. The transfer shaft is a predetermined bolt. The outer diameter of the hook is larger than the outer diameter of the support shaft so that it can be used as the head of the bolt. The height of the hook relative to the placement extension can be adjusted by tightening or loosening the placement extension and the bolt.

[0013] Furthermore, the present invention includes a protrusion placement part, which is detachably fastened to the aforementioned placement extension part and the independent groove structure, forming a predetermined groove for placing the protrusion of the aforementioned accessory. By changing the protrusion placement part according to the size of the aforementioned accessory, accessories of different specifications or sizes can be bent as a single device.

Whereas, even when terms are defined herein, they should not be construed as excluding the embodiments described herein.

[0026] Without departing from the spirit of the invention as claimed, those skilled in the art can implement various modifications, and such modifications should not be interpreted in a way that departs from the technical concept or prospects of the invention.

[0027] In describing the present invention, the terms “upper part”, “upper end”, “vertical”, “parallel”, etc., are defined based on the accompanying drawings, and such terms do not limit the shape and position of the various structures.

[0028] For the terms used in this specification, unless the context clearly indicates otherwise, singular expressions include plural expressions. It should be understood that terms such as "comprising" are used only to specify the presence of features, quantities, steps, operations, structural elements, components or combinations thereof, and do not preclude the presence or additional possibility of one or more other features, quantities, steps, operations, structural elements, components or combinations thereof.

[0029] According to an embodiment of the present invention, a component bending device with anti-jamming function is used to bend a component 5 so that the inlet 51 and outlet 51 have a predetermined angle, and is capable of disassembling the bent component 5. The device includes: a component placement section 1, which has a groove (component groove) 10 with a predetermined curvature, the groove being formed in a predetermined arc shape, such that the outer peripheral surface of the component 5 is placed thereon; and a separation section 2, disposed on one side of the component placement section 1, having a predetermined fixing structure and a separation structure, which is fixed during the component 5 bending process and, after the component 5 bending process, is moved to the groove of the component placement section 1. The spaced-out position provides space for disassembling the bent component 5; the transfer shaft 3 provides a path for transferring the separated part 2 and is arranged in a vertical direction along a plane including the arc forming the groove 10 of the component placement part 1; and the adjusting clamp 4 is arranged on the upper part of the transfer shaft 3 for adjusting the transition between the fixed state and the separated state of the separated part 2, so that the end of the component 5 is fixed during the bending process of the component 5, and the component 5 cannot move even if a load is applied from the outside, and the fixing of the end of the component 5 can be released after the bending process of the component 5.

[0030] In the above description, the terms "inlet 51 and outlet 51" are used to distinguish the two different holes of accessory 5. When using accessory 5, the direction of fluid flow does not limit the structural elements of the present invention.

[0031] The aforementioned "groove (part slot) 10 with a specified curvature" refers to a groove that can have a curvature that is larger than a specified size than the outer diameter of the part 5, so that the outer diameter of the part 5 to be bent can be placed.

[0032] The center angle of the "prescribed arc" of the aforementioned accessory placement part 1 can be from 60 degrees to 180 degrees. Depending on the requirements, products with a bending angle of 90 degrees ("┓" shaped accessory 5) to 180 degrees ("U" shaped accessory 5) can be manufactured based on the aforementioned center angle.

[0033] A load support portion 12 may be formed opposite the aforementioned accessory placement portion 1 (opposite to the center point of the aforementioned defined arc). The load support portion 12 can withstand the load applied to the accessory placement portion 1 by the accessory 5 during the bending process. More specifically, by reducing the torque applied to the connection point of the accessory placement portion 1 by applying a load to the accessory placement portion 1, damage to the equipment can be prevented, and the bending process can be performed under a larger load.

[0034] Alternatively, a groove (second accessory groove) with the specified curvature can be formed in the load support portion 12, having a different curvature than the groove (first accessory groove) 10 with the specified curvature formed in the accessory placement portion 1. This allows accessories 5 with different outer diameters to be bent using a single device. However, in this case, the load support portion 12 should also include the separation portion 2, the transfer shaft 3, the adjusting clamp 4, etc., which are structural elements of the present invention. These structural elements need to be appropriately configured so that they do not interfere with each other. Since this structure can be easily implemented with reference to the description of the present invention, further detailed descriptions will be omitted below.

[0035] Furthermore, the aforementioned separation portion 2 may include: a placement extension portion 11 having an extension groove 110, the extension groove 110 constituting part of the groove of the aforementioned accessory placement portion 1; and an independent groove structure 21, which is disposed separately from the groove of the aforementioned accessory placement portion 1 on the upper part of the placement extension portion 11 as an independent component, and has a groove corresponding to the extension groove 110 when in close contact with the aforementioned placement extension portion 11. The aforementioned transfer shaft 3 may include: a support shaft 30 fixed to one side of the aforementioned placement extension portion 11; a spring 31 connected to the aforementioned support shaft 30 to apply an upward elastic force to the independent groove structure 21; and a hook 32 for preventing the aforementioned independent groove structure 21 from detaching from the transfer shaft 3.

[0036] In contrast to the accessory slot 10 with a semi-circular cross-section, the aforementioned placement extension 11 may also be formed by extending only along a portion (lower part) of a cross-section with a 1 / 4 circular cross-section (an arc with a center angle of 90 degrees), or it may be formed by adding components of the aforementioned shape.

[0037] With this structure, accessory 5 is placed (half of it is inserted into the semi-circular groove) in accessory groove 10, and only 1 / 4 of the end of accessory 5 can be placed through the placement extension 11.

[0038] Therefore, if the above-mentioned independent groove structure 21 is closely attached to the upper part of the placement extension 11, only the remaining 1 / 4 part of the end of the accessory 5 is placed, and the end of the accessory 5 can be fixed (placed) between the placement extension 11 and the independent groove structure 21.

[0039] The aforementioned support shaft 30 can be connected in parallel or in series with the spring 31. Figures 1 to 6 An embodiment of the invention is shown in which the support shaft 30 and the spring 31 are connected in parallel (the support shaft 30 is inserted inside the spring 31). In the embodiment where the support shaft 30 and the spring 31 are connected in series, the hook 32 height adjustment function achieved by bolting the support shaft 30 as described below is not present.

[0040] Furthermore, the aforementioned adjusting clamp 4 includes: an adjusting body 4, disposed at the upper end of the aforementioned accessory placement part 1, fixed by a predetermined hinge, forming a predetermined elongated shape capable of rotating around the hinge; a hook rail 40, formed on the bottom surface of the adjusting body 4, such that when the adjusting body 4 rotates, the hook 32 does not interfere with the adjusting body 4; and a rod 41, connected to one side of the aforementioned adjusting body 4, for receiving predetermined power to rotate the adjusting body 4. The aforementioned separating part 2 includes: a handle 22, fixed to the aforementioned independent groove structure 21, extending in a direction parallel to the transfer shaft 3; and a hook through hole 211, formed in the independent groove structure 21, through which the hook 32 passes. 2. Prevent the independent groove structure 21 from detaching from the transfer shaft 3; and guide through hole 212, when the independent groove structure 21 moves in the vertical direction, perform a prescribed guiding function so that the independent groove structure 21 cannot sway in any direction other than the axial direction of the transfer shaft 3, and form an inner diameter smaller than the inner diameter of the hook through hole 211 at the lower part of the hook through hole 211, the transfer shaft 3 is a prescribed bolt, the outer diameter of the hook 32 is larger than the outer diameter of the support shaft 30 so that it can be used as the head of the bolt, and the height of the hook 32 relative to the placement extension 11 can be adjusted by fastening or loosening the placement extension 11 and the bolt.

[0041] In the above description, "elongated" refers to a shape with a specified length and / or a shape with a specified eccentricity. For example, a component with an elliptical, rectangular (as shown in the embodiment in the figure) cross-section or an arc shape, if the point (rotation axis) connected to the hinge is separated from the main body, a component with a circular or square cross-section can also be regarded as "elongated".

[0042] Workers in the process can operate the rod 41 and handle 22 manually or automatically through automatic devices.

[0043] When operated manually by staff, the fixed and detached states can be changed by using the operating lever 41 while holding and pressing the handle 22.

[0044] Preferably, the outer diameter of the hook 32 is smaller than the outer diameter of the hook through hole 211 by a specified size, and the outer diameter of the support shaft 30 is smaller than the inner diameter of the guide through hole 212 by a specified size.

[0045] With the upper hook 32 being stopped by the shoulder formed between the hook through hole 211 and the guide through hole 212, the adjusting body 4, which passes through the hook through hole 211 and the guide through hole 212 and moves up and down, can limit the height of the upper end.

[0046] Alternatively, the through hole 211 and the guide through hole 212 may have the same inner diameter, allowing a specified shoulder to be formed between them. For example... Figure 4In the embodiment shown, the inner diameters of the hook through hole 211 and the guide through hole 212 can be the same.

[0047] Furthermore, the present invention includes a protrusion placement part 23, which is detachably fastened to the placement extension part 11 and the independent groove structure 21 respectively, and forms a predetermined groove 230 to place the protrusion 52 of the accessory 5. By changing the protrusion placement part 23 according to the size of the accessory 5, the present invention can be used as a single device to bend accessories 5 of different specifications or sizes.

[0048] The aforementioned protrusion placement part 23 can be detachably fastened to the end side of the placement extension part 11 and the side of the independent groove structure 21 by means of specified bolts / screws, etc.

[0049] The aforementioned protrusion placement portion 23 can be used to place / fix any one of the protrusions 52 of the aforementioned accessory 5. To place a protrusion 52 with a specified polygonal shape, such as a screw head, a specified polygonal shape corresponding to the protrusion 52 can be formed. Figure 2 In order to place the accessory 5 with the hexagonal protrusion 52, a specified trapezoidal protrusion placement part 23 can be formed.

[0050] According to the structure described above, when the outer diameter of the accessory 5 is smaller than that of the accessory groove 10, the wiring portion parallel to the central axis of the accessory 5 is in close contact with the accessory groove 10, and is supported / fixed by the accessory placement part 1 due to bending, and can receive the load from the bending mold.

[0051] Furthermore, when manufacturing accessories using the aforementioned accessory bending device with anti-jamming function, the provided accessory manufacturing method may include the following steps: engaging a bushing with the thread 53 of the accessory 5; placing the accessory 5 in the accessory placement part 1; fixing the accessory 5 using the adjusting clamp 4; inserting a fixing shaft into one side of the accessory 5; bringing the bushing into contact with the clamp; applying a load by rotating the bending die to bend the portion engaged with the bushing relative to the portion fixed by the fixing shaft; moving the fixing shaft and the clamp backward; separating the accessory 5 from the accessory placement part 1 using the adjusting clamp 4; and separating the bushing from the accessory 5.

[0052] The aforementioned clamp may include: a first clamp for supporting any protrusion 52 of the aforementioned accessory 5; and a second clamp for supporting the bushing. With the first clamp and the second clamp fixed, the accessory 5 can be bent with the center of the accessory groove 10 as a reference by rotating the bending die.

[0053] The following is for reference Figure 6 Explain the bending process.

[0054] First, such as Figure 6As shown in part (a), when the independent slot structure 21 is pressed tightly against the placement extension 11 using the handle 22, the independent structure 21 can be fixed by rotating the adjustment body 4 using the rod 41. In this case, the hook 32 passes through the hook through hole 211 and is housed inside the adjustment body 4.

[0055] Next, as Figure 6 As shown in part (b), the fitting 5 with the bushing is placed in the fitting placement part 1. In the placed state, the bushing and the protrusion 52 or the main body of the fitting 5 at the other end are fixed by moving the clamp forward.

[0056] Subsequently, as Figure 6 As shown in section (c), with the fixed part 5 in the fixed state, a specified load is applied by rotating (referring to rotation based on the center point of the aforementioned "specified arc") the bending die connected to any of the fixtures to bend the part 5. After bending is completed, the fixture is moved backward again.

[0057] Finally, as Figure 6 As shown in section (d), the accessory can be easily separated by operating the separation section 2. Furthermore, the bent accessory 5 can be removed from the accessory placement section 1.
