Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, and in particular to an arc-pressing device. Background Technology

[0002] In the existing technology, there is a type of sensor that, when used in conjunction with a pipeline, requires an external metal sheath to enhance the integration of the sensor and the pipeline. Since the diameters of the sensor and the pipeline are different, when they are externally connected and enclosed by a metal sheath, gaps appear between the sensor, pipeline, and metal sheath at the diameter-changing point. This results in inaccurate data acquisition by the sensor due to the metal sheath forming a common tangent to the sensor and pipeline in the radial direction. Utility Model Content

[0003] In view of this, the present invention provides an arc-pressing device, which enables the metal sheet to be pressed into an arc, thus making the wrapping of the sensor and pipeline more precise. Therefore, the data acquired by the sensor is more accurate and thus more suitable for practical use.

Let the center distance between the limiting blind hole (36) and the first through hole (22) be d1, and the center distance between the sixth through hole (32) and the seventh through hole (33) be d2. Then d1 = d2, so that when the lower die (12) rotates to the position corresponding to either the limiting blind hole (36) or the seventh through hole (33), the second limiting screw (26) is simultaneously inserted into the limiting blind hole (36) and the seventh through hole (33), and the relative positional relationship between the lower die (12) and the base (1) can be temporarily locked.

Detailed Implementation

[0063] In view of this, the present invention provides an arc-pressing device, which enables the metal sheet to be pressed into an arc, thus making the wrapping of the sensor and pipeline more precise. Therefore, the data acquired by the sensor is more accurate and thus more suitable for practical use.

[0064] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation, structure, features, and effects of an arc-suppressing device proposed according to this utility model. In the following description, different "embodiments" or "embodiments" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0065] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships, such as A and / or B. Specifically, it can mean that A and B can be included at the same time, A can exist alone, or B can exist alone, and any of the above three situations can be met.

[0066] See appendix Figure 1 - Appendix Figure 16 The arc pressing device provided by this utility model includes an upper pressing die 34 and a lower pressing die 12. The upper pressing die 34 is provided with a protrusion, so that the platform of the upper pressing die 34 facing downward has a first planar platform in addition to the protrusion; the lower pressing die 12 is provided with a recess, so that the platform of the lower pressing die 12 facing upward has a second planar platform in addition to the recess; when the upper pressing die 34 and the lower pressing die 12 are pressed together, the protrusion and the recess engage with each other, and the first planar platform and the second planar platform engage with each other, so that the metal sheet 29 is located in the gap between the upper pressing die 34 and the first planar platform and the second planar platform of the lower pressing die 12, and is pressed to obtain an arc-shaped surface with the same shape as the gap.

[0067] The arc-pressing device provided by this utility model uses the gap formed by the pressing of the upper pressing mold 34, the lower pressing mold 12, the first planar platform, and the second planar platform to press the metal sheet 29. This allows the arc-shaped surface formed by pressing the metal sheet 29 to form a concave corner at the transition between the first and second planar platforms. When the metal sheet 29 is used to wrap the sensor or pipeline, this concave corner can fill the gap formed at the change of diameter of the sensor or pipeline. Therefore, the wrapping of the sensor or pipeline by the metal sheet 29 can be more precise, and the data acquired by the sensor can be more accurate.

[0068] The device comprises multiple protrusions and recesses of different diameters, with each protrusion and recess corresponding to a different diameter. In this configuration, the one-to-one correspondence between the multiple pairs of protrusions, recesses, and corresponding planar platforms allows the metal sheet 29 within their gaps to be arc-shaped into arcs of various diameters, thus adapting to sensors of different diameters. Therefore, the industrial applicability of the arc-pressing device provided in this embodiment is improved.

[0069] The protrusions include a first arc-shaped protrusion 6, a second arc-shaped protrusion 7, a third arc-shaped protrusion 8, and a fourth arc-shaped protrusion 20. The recesses include a first arc-shaped groove 13, a second arc-shaped groove 14, a third arc-shaped groove 19, and a fourth arc-shaped groove 21. The upper die 34 is in the shape of a first cube, providing four planes axially, on which the first arc-shaped protrusion 6, the second arc-shaped protrusion 7, the third arc-shaped protrusion 8, and the fourth arc-shaped protrusion 20 are respectively disposed. The lower die 12 is in the shape of a second cube, with the first arc-shaped groove 13, the second arc-shaped groove 14, the third arc-shaped groove 19, and the fourth arc-shaped groove 21 respectively formed on its upper plane. The first arc-shaped protrusions 6 and 13 correspond to each other, the second arc-shaped protrusions 7 and 14 correspond to each other, the third arc-shaped protrusions 8 and 19 correspond to each other, and the fourth arc-shaped protrusions 20 and 21 correspond to each other. In this case, the protrusion can be shaped into four different diameter arcs by utilizing the corresponding first arc protrusion 6, first arc groove 13, second arc protrusion 7, second arc groove 14, third arc protrusion 8, third arc groove 19, fourth arc protrusion 20, fourth arc groove 21 and associated planar platform. Furthermore, the upper die 34 and the lower die 12 are both cubic in shape, resulting in better integration and easier use.

[0070] The arc-pressing device provided in this embodiment of the present invention further includes a base 1, a handle 16, a first connecting ear 3, a second connecting ear 4, and a first limiting pin 2. A through hole 35 is provided at the center of the upper pressing mold 34, and the handle 16 passes through the through hole 35. The first connecting ear 3 and the second connecting ear 4 are respectively connected to the base, forming a first accommodating space between them. The first connecting ear 3 has a fourth through hole 27, and the second connecting ear 4 has a fifth through hole 28. The first connecting part 5 of the handle 16 has a second through hole 23 arranged radially, and the first connecting part 5 is accommodated within the accommodating space. The positions of the fourth through hole 27, the fifth through hole 28, and the second through hole 23 correspond to each other. The first limiting pin 2 passes through the second through hole 23, the fourth through hole 27, and the fifth through hole 28 simultaneously, allowing the handle 16 to rotate around the first limiting pin 2 as the rotation center. When the handle 16 rotates to the lower limit position, the metal sheet 29 can be pressed into an arc-shaped surface of the same shape within the gap between the corresponding arc-pressing protrusion and the arc-pressing groove. In this case, it is only necessary to rotate the upper die 34 relative to the handle 16 and change the position of the lower die 12 to make the metal sheet 29 be pressed into four arcs of different diameters, making the transformation method simpler.

[0071] The arc-pressing device provided in this embodiment of the present invention also includes a second limiting pin 30. A connector 9 is formed at the center of the upper die 34, and one end of the connector 9 forms a first claw 9a, a second claw 9b, a third claw 9c, and a fourth claw 9d. A first gap is formed between the first claw 9a and the second claw 9b; a second gap is formed between the second claw 9b and the third claw 9c; a third gap is formed between the third claw 9c and the fourth claw 9d; and a fourth gap is formed between the fourth claw 9d and the first claw 9a. The first and third gaps correspondingly form a second accommodating space, and the second and fourth gaps correspondingly form a third accommodating space. A third through hole 24 is provided on the connector portion 18 of the handle 16. When the handle 16 is inserted into the through hole 35 and the upper die 34 is rotated to the first pressing arc position, the second receiving space and the third through hole 24 correspond, and the second limiting pin 30 simultaneously passes through the third through hole 24 and the second receiving space, so that the first pressing arc protrusion 6 and the first pressing arc groove 13 are locked in opposite positions. When the handle 16 is inserted into the through hole 35 and the upper die 34 is rotated to the second pressing arc position, the second receiving space and the third through hole 24 correspond, and the second limiting pin 30 simultaneously passes through the third through hole 24 and the second receiving space, so that the fourth pressing arc protrusion 20 and the fourth pressing arc groove 21 are locked in opposite positions. When the handle 16 is inserted into the through hole 35 and the upper die 34 is rotated to the third pressing arc position, the third receiving space and the third through hole 24 correspond, and the second limiting pin 30 simultaneously passes through the third through hole 24 and the third receiving space, so that the second pressing arc protrusion 7 and the second pressing arc groove 14 are locked in opposite positions. When the handle 16 is inserted into the through hole 35, and the upper die 34 is rotated to the fourth arc-pressing position, the third accommodating space and the third through hole 24 correspond, and the second limiting pin 30 simultaneously passes through the third through hole 24 and the third accommodating space, so that the third arc-pressing protrusion 8 and the third arc-pressing groove 19 are locked in opposite positions. In this case, when the upper die 34 rotates relative to the handle 16, the relative position between the upper die 34 and the handle 16 can be temporarily fixed by the second limiting pin 30, making the arc-pressing operation of the metal sheet 29 more stable.

[0072] The lower die 12 is provided with a relief groove 31. The relief groove 31 corresponds to the lower stop point of the second stop pin 30. In this case, the relief groove 31 allows fingers or other tools to be inserted into the relief groove 31 when the second stop pin 30 is installed and removed, thereby making it easier to operate the second stop pin 30.

[0073] The arc-pressing device provided in this embodiment of the invention also includes a limiting member 10. The inner wall of the limiting member 10 is provided with an internal thread, and the transition portion 17 of the handle 16 is provided with an external thread. When the handle 16 is inserted into the through hole 35, the limiting member 10 is fitted onto the transition portion 17. Furthermore, the engagement between the internal and external threads locks the relative position of the upper die 34 and the handle 16. In this case, the upper die 34 can further limit its axial relative position to the handle 16 through the engagement between the limiting member 10 and the transition portion 17 of the handle 16, resulting in more stable performance when arc-pressing the metal sheet 29.

[0074] The arc-pressing device provided in this embodiment of the invention also includes a first limiting screw 25. The base 1 has a sixth through hole 32, and the lower pressing die 12 has a first through hole 22. The sixth through hole 32 and the first through hole 22 correspond to each other. The first limiting screw 25 passes through both the sixth through hole 32 and the first through hole 22, allowing the lower pressing die 12 and the base 1 to rotate around the first limiting screw 25 as the rotation center. In this case, when rotating the lower pressing die 12 to align the first arc-pressing groove 13, the second arc-pressing groove 14, the third arc-pressing groove 19, and the fourth arc-pressing groove 21 with their corresponding arc-pressing protrusions, the operation is simpler.

[0075] The arc-pressing device provided in this embodiment of the invention also includes a second limiting screw 26. Limiting blind holes 36 are respectively provided on the bottom surface of the lower die 12, corresponding to the first arc-pressing groove 13, the second arc-pressing groove 14, the third arc-pressing groove 19, and the fourth arc-pressing groove 21. A seventh through hole 33 is provided on the base 1. Let the center distance between the limiting blind hole 36 and the first through hole 22 be d1, and the center distance between the sixth through hole 32 and the seventh through hole 33 be d2. Then d1 = d2, so that when the lower die 12 rotates to any position corresponding to either the limiting blind hole 36 or the seventh through hole 33, the second limiting screw 26 simultaneously passes through both the limiting blind hole 36 and the seventh through hole 33, temporarily locking the relative position between the lower die 12 and the base 1. In this case, the locking relationship between the second limiting screw 26 and the limiting blind hole 36 enables temporary positioning of the lower die 12, making the operation more stable when arc-pressing the metal sheet 29.

[0076] The arc-pressing device provided in this embodiment of the invention further includes at least three support legs 15. The support legs 15 are fixedly connected to the bottom surface of the base 1. In this case, the support legs 15 make the base 1 more stable on a horizontal surface. In this embodiment, the base 1 can be leveled using each support leg 15. Furthermore, the base 1 can be made of rubber or a pressure-deformable material, increasing the damping between the arc-pressing device and the horizontal surface when the arc-pressing device is placed on a horizontal surface. This makes the operation safer and more stable when using the arc-pressing device to press the metal sheet 29 into an arc.
