Description

Technical Field

[0001] The invention relates to the technical field of automobile parts processing equipment, and in particular to a bending and punching device for automobile parts processing. Background Art

[0002] An existing automobile part is processed by unwinding the steel coil using a decoiler, then gradually forming a curved edge through rolling, then punching it using a punching machine, then cutting it, then bending it to form a certain arc, and finally punching a side hole to complete the processing.

In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0055] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0056] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0057] like Figure 1 to Figure 6 As shown, a bending and punching device for automobile parts processing is proposed, including an unwinding machine 1, the unwinding machine 1 includes a frame 2; a rotating shaft 3 is rotatably arranged on the frame 2; a supporting arm 4 is movably arranged on the rotating shaft 3, and the moving direction is parallel to the radial direction of the rotating shaft 3, and the supporting arm 4 has a groove 5; a limiting member 6 is movably arranged in the groove 5, and the limiting member 6 has a connected through hole 7 and a truncated cone hole 8; a locking member 9 is arranged in the groove 5, located on one side of the limiting member 6, and the locking member 9 has a through hole 10 communicating with the truncated cone hole 8, and the locking member 9 also has a plurality of elastic portions 11, which are arranged in a circle around the through hole 10 at intervals and abut against the inner wall of the truncated cone hole 8; the side baffle 12 has a guide portion 13, which passes through the through hole 7, the truncated cone hole 8 and the through hole 10 in sequence and is moved and arranged in the groove 5, and after the limit member 6 moves, the plurality of elastic portions 11 gather to press the guide portion 13 or spread out to release the guide portion 13.

[0058] In this embodiment, in order to solve the problem in the related art that the side baffle 12 of the uncoiler 1 is not convenient to adjust according to the actual width of the steel coil, the side baffle 12 is set to be movable, so that the position can be adjusted in real time according to the width of the steel coil, thereby adapting to steel coils of different sizes, which is more practical.

[0059] Specifically, the uncoiler 1 is built on a solid frame 2, with a rotating shaft 3 as its core. The support arm 4 can move radially along the rotating shaft 3 to adapt to steel coils with different inner diameters. A groove 5 is built into the support arm 4, and a limiting member 6 is installed in the groove 5. The limiting member 6 has a through hole 7 and a truncated cone hole 8, through which the guide portion 13 of the side baffle 12 can pass and provide a certain guide. The locking member 9 is arranged in the groove 5. On one side of the limiting member 6, the elastic portion 11 of the locking member 9 is arranged around the through hole 10. After the side baffle 12 adjusts its position, the limiting member 6 is moved to make the truncated cone hole 8 squeeze or loosen the elastic portion 11, so that the elastic portion 11 gathers and presses the guide portion 13, or spreads out to release the guide portion 13, thereby realizing flexible adjustment and locking of the side baffle 12, and realizing the position adjustment of the side baffle 12 simply and quickly.

[0060] Furthermore, the uncoiler 1 also includes a guide sleeve 14, which is arranged on the frame 2; a guide column 15 is arranged on the guide sleeve 14 for lifting; a support plate 16 is arranged on the guide column 15 and follows the lifting, and is located below the rotating shaft 3.

[0061] In this embodiment, a support plate 16 is further provided below the uncoiler 1 to support the steel coil when loading the steel coil, thereby improving safety and reducing the supporting pressure of the uncoiler 1 .

[0062] Furthermore, the uncoiler 1 also includes a connecting frame 17, which is arranged on the support plate 16; a roller 18 is rotatably arranged on the connecting frame 17; a moving member 19 is movably arranged on the frame 2, and the moving member 19 has a through groove 20, which is inclined from top to bottom, and the roller 18 is located in the through groove 20. After the moving member 19 moves, it is used to drive the roller 18 to rise and fall.

[0063] In this embodiment, the driving method for lifting and lowering the support plate 16 is that the inclined through slot 1 20 on the moving member 19 guides the roller 18 to lift and lower, thereby realizing flexible adjustment of the height of the support plate 16 .

[0064] Furthermore, the support plate 16 has an avoidance hole 21, and the uncoiler 1 also includes a lifting member 22, which is lifted and lowered on the frame 2 and is located below the avoidance hole 21, and the lifting member 22 has a tooth portion 23; the bracket 24 is set on the frame 2 and is located between the lifting member 22 and the connecting frame 17; the transmission gear 25 is rotatably set on the bracket 24, and the connecting frame 17 has a tooth portion 26, and the transmission gear 25 is meshed with both the tooth portion 1 23 and the tooth portion 26.

[0065] In this embodiment, after the uncoiler 1 props up the steel coil, the support plate 16 is no longer needed for support. At this time, the support plate 16 can be lowered, and at the same time, the transmission of the tooth portion 1 23, the transmission gear 25 and the tooth portion 26 will drive the lifting member 22 to rise, so that the lifting member 22 passes through the avoidance hole 21 on the support plate 16 and abuts against the steel belt at the bottom of the steel coil to prevent it from being too loose and affecting the transportation. When the steel coil is rolled up, the lifting member 22 can press the bottom steel belt tightly against the steel coil, so that the steel coil will not be loose when it is rolled up.

[0066] Furthermore, the limiting member 6 is arranged on the groove 1 5 by a thread to move.

[0067] In this embodiment, the limiting member 6 is moved by a thread setting, and after being screwed, it can compress the elastic part 11 and fix itself tightly to avoid loosening itself, which will cause the elastic part 11 to loosen, thereby affecting the locking of the side baffle 12.

[0068] Furthermore, it also includes a puncher 27 arranged on one side of the uncoiler 1, and the puncher 27 includes a frame 28, and the frame 28 is located on one side of the frame 1 2; a punching body 29 is raised and lowered on the frame 28; an extension plate 30 is arranged on the punching body 29; a material removing piece 31 is arranged on the extension plate 30, and the material removing piece 31 is used to push away the waste material adhering to the steel strip after being raised and lowered.

[0069] In this embodiment, considering that some of the punched waste may still adhere to the steel belt and need to be removed manually, which is labor-intensive, a material removal piece 31 is added. When the punching body 29 is performing a punching operation, the material removal piece 31 will pass through the punched position. If the waste accidentally adheres to the steel belt, the material removal piece 31 will push the waste away, saving manpower.

[0070] Furthermore, it also includes a guide block 32, which is arranged on the frame 28 and is located below the material removal piece 31. The guide block 32 has a guide slope 33. The material removal piece 31 is swingably arranged on the extension plate 30. After the material removal piece 31 descends, it abuts against the guide slope 33 and gradually swings to push the steel strip forward.

[0071] In this embodiment, in order to assist the forward traction of the steel strip, a guide block 32 is also provided at the bottom of the material removal piece 31. The material removal piece 31 will pass through the punched position before the punching body 29, and then will contact the guide slope 33 of the guide block 32, and gradually swing and tilt, pushing the steel strip forward. After moving to the preset position, the punching body 29 just falls down to punch the holes. After an unexpected failure in the traction of the steel strip, this method can temporarily replace the original traction method to achieve non-stop processing.

[0072] Furthermore, a limiting column 34 is included, which is arranged on the punching body 29 and is located on one side of the material removal piece 31 .

[0073] In this embodiment, the material removal piece 31 can realize its own swing reset by using a torsion spring, and the limiting column 34 is used to limit the material removal piece 31 to prevent it from swinging excessively.

[0074] Furthermore, it also includes a sleeve 35, which is arranged on the rotating shaft 3; one end of a connecting rod 36 is hinged on the support arm 4, and the other end is hinged on the sleeve 35; a threaded rod 37 is arranged on the rotating shaft 3; a moving part 38 is threadedly arranged on the threaded rod 37, and the threaded rod 37 is used to drive the moving part 38 to move after the rotation of the threaded rod 37, and the moving part 38 moves closer to or away from the rotating shaft 3 after the movement; a sleeve 39 is arranged on the moving part 38; one end of a connecting rod 40 is hinged on the sleeve 39, and the other end is hinged on the support arm 4.

[0075] In this embodiment, sleeve 1 35 is fixed on the rotating shaft 3 and does not move in the circumferential direction, that is, the support arm 4 can move radially but cannot rotate. In order to simply and quickly drive the support arm 4 to extend and retract radially, a threaded rod 37 at one end is added to the rotating shaft 3. A moving part 2 38 is threadedly arranged on the threaded rod 37. When the threaded rod 37 rotates, it drives the moving part 2 38 to move. The moving part 2 38 reciprocates on the threaded rod 37, approaching or moving away from the rotating shaft 3, thereby driving sleeve 2 39 arranged thereon to move axially, and then pushes connecting rod 2 40 to prop up or pull back the support arm 4. That is, through the arrangement of sleeve 1 35, connecting rod 1 36, connecting rod 2 40, threaded rod 37, moving part 2 38 and sleeve 2 39, the moving part 2 38 can be rotated to realize the radial extension and retraction of the support arm 4 to adapt to steel coils with different inner diameters, which is simple and quick.

[0076] Furthermore, there are a plurality of support arms 4 , which are spaced apart and distributed around the rotating shaft 3 in a circle.

[0077] In this embodiment, in order to improve the stability of the uncoiler 1, a plurality of support arms 4 are provided.

[0078] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
