Detailed Description of the Embodiment

[0036] The present utility model will be further described in detail below in conjunction with the drawings and the specific embodiments.

[0037] For the sake of simplicity of the drawings, only the parts related to the utility model are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, for the sake of simplicity and easy understanding of the drawings, for the parts with the same structure or function in some figures, only one of them is schematically shown, or only one of them is marked. In this article, "one" not only means "only this one", but also can mean the situation of "more than one", and "several" includes "two" and "more than two".

[0038] In this article, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "linkage" 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 directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0039] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0040] As Figures 1-6 shown, an automobile accessory bending mechanism includes a mold 1 and further includes: a workbench 2, the mold 1 is arranged on the workbench 2; a limiting device 3, there are two of them, the limiting device 3 is arranged on the workbench 2, and the two limiting devices 3 are respectively arranged on both sides of the mold 1. The limiting device 3 includes: a mounting table 301, the mounting table 301 is arranged on the workbench 2; a positive and negative lead screw 302, rotatably arranged on the mounting table 301; two threaded pipes 303, the two threaded pipes 303 are respectively threadedly connected to both sides of the positive and negative lead screw 302, and the threaded pipes 303 are slidably arranged on the mounting table 301; two limiting wheels 304, the two limiting wheels 304 are respectively rotatably sleeved on the two threaded pipes 303. The limiting wheel 304 has a support wheel 3041 and a limiting ring 3042. The limiting ring 3042 is arranged on one side of the support wheel 3041. The support wheel 3041 is used for rotatably supporting the lower end of the accessory, and the limiting ring 3042 abuts against the vertical side surface of the accessory. The accessory is located between the two limiting rings 3042 on both sides.

[0041] During use, the threaded pipe 303 slides on the installation table 301 and cannot rotate. By rotating the left and right lead screw 302, the threaded pipes 303 on the front and rear sides move relative to each other to adjust the interval between the two limit rings 3042 to suit the size of the fitting. Place the fitting on the support wheel 3041, and the two limit rings 3042 on both sides limit the fitting in the front and rear directions. Among the two limit devices 3, four-point limiting is formed to prevent the fitting from skewing. The lower end of the fitting also abuts against the upper end of the mold 1. When stamping and bending, the bending line can be manually adjusted relative to the mold 1 (i.e., relative to the stamping head). During adjustment, the fitting can slide and adjust on the support wheel 3041, which is convenient for adjustment and will not skew, only making adjustments in the left and right directions.

[0042] Furthermore, it further includes a positioning device 4. The positioning device 4 includes: a sliding seat 401 slidably disposed on the workbench 2. The sliding seat 401 moves closer to or away from the mold 1 after sliding, and the sliding seat 401 is located beside the installation table 301; a guiding frame 402 disposed on the sliding seat 401; a lifting plate 403 vertically disposed on the sliding seat 401 along the guiding frame 402. Both sides of the lifting plate 403 have mounting portions 4031; there are two flipping plates 404, and each mounting portion 4031 rotatably disposes one flipping plate 404. One side of the flipping plate 404 close to the mold 1 has a positioning groove 4041. The vertical cross-section of the positioning groove 4041 is in the shape of ">", and the side walls on the upper and lower sides of the positioning groove 4041 are both used to abut against the end of the fitting.

[0043] During use, the positioning device 4 can achieve positioning in the left and right directions, more accurately and quickly positioning the fitting to ensure precise bending. When bending a certain fitting, the distance between the bending line of the fitting and the end face remains unchanged. Set the distance between the flipping plate 404 and the mold 1. When the end of the fitting abuts in the positioning groove 4041, the bending line can be positioned. The vertical cross-section of the positioning groove 4041 is in the shape of ">", and the opening direction points to the right end of the fitting. When the middle tip position of the positioning groove 4041 is opposite to the middle in the thickness direction of the fitting, the upper and lower two edges of the end of the fitting abut against the upper and lower two inclined side walls of the positioning groove 4041. One fitting can be used to position the flipping plate 404 first. After placing one fitting on the support wheel 3041 and adjusting the bending line position, manually fix the left and right directions of the fitting, then move the sliding seat 401, and the flipping plate 404 approaches the right end of the fitting. The lifting plate 403 moves up and down to make the positioning groove 4041 opposite to the end of the fitting, and finally make the upper and lower side walls of the positioning groove 4041 respectively abut against the upper and lower two edges of the end of the fitting, and the position of the flipping plate 404 is set. After that, other fittings can be based on this.

[0044] The flip plate 404 is provided with a positioning groove 4041, which can limit the accessory from the upper and lower directions (note here that it is not fixed, but only serves as a limit prompt). If the accessory is tilted in the upper and lower directions, the end of the accessory cannot be well abutted with the two positioning grooves 4041 at the same time, and timely adjustment can be made. Under the guidance of the upper and lower inclined side walls of the positioning groove 4041, it has a certain guiding and correcting effect. When bending, the accessory is deformed and the end moves upward, which will drive the flip plate 404 to rotate until the end of the accessory is separated from the positioning groove 4041, and the flip plate 404 flips down and resets under its own weight. By rotating the flip plate 404, a better positioning effect is achieved for the end of the accessory, and the obstruction to the movement of the end of the accessory can be reduced during the bending process, reducing wear.

[0045] The rotation connection position of the flip plate 404 and the mounting portion 4031 may be on the other side opposite to the positioning groove 4041. The lifting plate 403 is lifted and lowered along the guide frame 402. The guide frame 402 may be a gantry structure to limit the rotation of the lifting plate 403. Two guide frames 402 may be provided. The two mounting portions 4031 are respectively located outside the two guide frames 402. The lifting and lowering adjustment of the lifting plate 403 may adapt to accessories of different thicknesses. The mounting portion 4031 may be a plate-shaped structure. The flip plate 404 is located on the upper side of the mounting portion 4031. The positioning groove 4041 in the shape of “>” also has an adaptive effect on accessories of different thicknesses.

[0046] Furthermore, one side of the workbench 2 has a threaded seat 201; the positioning device 4 also includes: a positioning screw 405, which is threadedly connected to the threaded seat 201, and the end of the positioning screw 405 is rotatably connected to the slide seat 401 to drive the slide seat 401 to slide.

[0047] When in use, the positioning screw 405 cooperates with the threaded seat 201 to drive the sliding seat 401 to slide left and right, and at the same time has a good self-locking positioning effect.

[0048] Furthermore, the lifting plate 403 has a threaded portion 4032 in the middle; the positioning device 4 also includes: a lifting screw 406, the lower end of which is rotatably connected to the slide seat 401, and the lifting screw 406 is threadedly connected to the threaded portion 4032 for driving the lifting plate 403 to rise and fall.

[0049] When in use, the lifting screw 406 can drive the lifting plate 403 to move up and down when it rotates, and at the same time change the height of the two mounting parts 4031, so that the height consistency of the flip plates 404 on both sides is good. The structural strength of the lifting plate 403 can be enhanced by setting reinforcing ribs.

[0050] Furthermore, the mounting table 301 is slidably arranged on the workbench 2. After the mounting table 301 slides, it approaches or moves away from the mold 1. The workbench 2 is provided with a chute 202, and the workbench 2 is slidably connected to the chute 202. The upper end of the workbench 2 is provided with a socket groove 203, and the mold 1 is inserted into the socket groove 203.

[0051] During use, the chute 202 is arranged on the workbench 2 in the left-right direction. The mounting table 301 slides left and right, and the distance between the two mounting tables 301 can be changed. The mold 1 is located between the two mounting tables 301. The sliding arrangement of the mounting table 301 is convenient for adapting to molds 1 with different left-right widths, improving applicability. The lower end of the mounting table 301 may have a convex block that is slidably adapted to the chute 202, which is a prior art means and will not be shown in detail. The slid mounting table 301 can be tightly positioned by structures such as bolts, or it can not be positioned. Frictional contact has a certain positioning effect, and the left-right positioning requirement for the mounting table 301 is not high. The limiting device 3 is mainly used for front-back direction positioning.

[0052] The socket groove 203 is arranged on the workbench 2, and the mold 1 is inserted and installed, which is relatively convenient for disassembly and assembly and can play a good positioning role for the mold 1. The socket groove 203 can be a plurality of hole-shaped structures or a strip-shaped structure, etc.

[0053] Furthermore, the mounting table 301 has a mounting groove 3011, and the mounting groove 3011 is arranged parallel to the forward and reverse lead screw 302; the limiting device 3 further includes: a plurality of sliders 305, the sliders 305 are slidably arranged in the mounting groove 3011; a support plate 306, which is arc-shaped, is arranged on the slider 305 and is used to abut against the circumferential side surface of the support wheel 3041.

[0054] During use, the support block and the slider 305 can slide in the mounting groove 3011. When the support block slides to the lower side of the support wheel 3041, it plays a supporting role for the support wheel 3041. At the same time, the support wheel 3041 can rotate, which can reduce the force on the forward and reverse lead screw 302. Especially when the support wheel 3041 needs to bear more pressure, the support block can be slid to the lower side to increase the supporting force. For example, when the mounting table 301 is close to the side of the mold 1 and the accessory is bent, the support wheel 3041 is required to always support the accessory. At this time, the mounting table 301 also needs to be locked and positioned in the left-right direction.
