[0030] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0033] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0034] In the process of producing and verifying the prototype of a new model, it is necessary to design and produce a special hemming mold according to the 3D data of the car door frame column, such as Figure 1 and Figure 2 The product 10 is a car door frame pillar. The pillar inner plate 11 and the pillar outer plate 12 of the car door frame pillar need to be edged. Specifically, the bent portion of the pillar outer plate 12 is pressed onto the pillar inner plate 11 to achieve the encapsulation of the pillar inner plate 11 and the pillar outer plate 12. The product 10 after the edge encapsulation process can be referred to Figure 3 and Figure 4 shown.

[0035] In the prior art, the production demonstration of new model prototypes requires the development of a set of hemming molds. When the hemming mold is operated, refer to Figure 5 First, debug the hemming mold, and then place the column outer plate and column inner plate before hemming in the lower mold cavity 23 of the hemming mold according to the operating standard. At this time, the column inner plate and column outer plate are in an unclosed state. Then start the hydraulic press 21, the hydraulic press 21 drives the upper table 22 downward, and the upper table 22 drives the upper mold cavity 24 downward to fit the lower mold cavity 23. At this time, the state of the hemming mold is as follows: Figure 6 After the upper die cavity 24 and the lower die cavity 23 are pressed together and held under pressure for 2 seconds, the hydraulic press 21 drives the upper table 22 upward, and the upper table 22 drives the upper die cavity 24 upward to the starting position, so as to achieve the encapsulation of the column inner plate and the column outer plate.

[0036] However, the hemming mold of the automobile door frame pillar must use a dedicated hemming mold and corresponding hemming equipment, which has a long development cycle and high development cost. In view of this, the present application presents an automobile door frame pillar hemming tooling, which can realize the hemming of the pillar inner plate and the pillar outer plate in place without developing a dedicated hemming mold and hemming equipment.

[0037] Reference Figure 7 and Figure 8 , describes a car door frame column edge wrapping tool, including an operating table 312, a hinge seat 321, a pressing rod 331 and a pressing upper module 342. In some embodiments thereof, the car door frame column edge wrapping tool also includes a maintenance table, and the operating table 312 is the upper end surface of the maintenance table 311.

[0038] The operation table 312 is provided with a lower pressing module 313, which is used to support the product 10. The upper pressing module 342 is located above the lower pressing module 313. By driving the upper pressing module 342 downward, the outer plate 12 of the column of the product is folded so that the outer plate 12 of the column and the inner plate 12 of the column are completely fitted together. Figure 3 and Figure 4 As shown, the pillar inner plate 11 and the pillar outer plate 12 can be wrapped in place.

[0039] In this embodiment, the pressing rod 331 is used to drive the pressing upper module 342 downward. Specifically, the hinge seat 321 is set on the operation table 312, and the front end of the pressing rod 331 is hinged to the hinge seat 321, so that the pressing rod 331 can rotate around the hinge point, thereby realizing the lifting and pressing of the pressing rod 331. Figure 7 As shown, the upper pressing module 342 is located within the movable range of the pressing rod 331 so that the pressing rod 331 can drive the upper pressing module 342 downward during the pressing process, thereby pressing down the product on the lower pressing module 313.

[0040] It is understandable that, during operation, the hinge seat 321 is fixed on the operating table 312, and the clamping rod 331 is hinged to the hinge seat 321. In one embodiment of the utility model, the lower part of the hinge seat 321 is fixedly connected to the operating table 312, and a rod through hole 322 is provided on the upper part of the hinge seat 321. The front end of the clamping rod 331 passes through the rod through hole 322, and the clamping rod 331 is provided with a first limiting assembly to limit the clamping rod 331 in the rod through hole 322, so as to limit the front and rear positions of the clamping rod 331. Furthermore, the first limiting assembly includes two first limiting columns 332 fixed to the front end of the clamping rod 331, and the two first limiting columns 332 are respectively located on the front and rear sides of the rod through hole 322, so as to clamp the clamping rod 331 in the rod through hole 322 through the two first limiting columns 332, thereby realizing the hinge connection between the clamping rod 331 and the hinge seat 321. Figure 7 and Figure 8 As shown, the height dimension of the through-rod hole 322 is greater than the diameter dimension of the clamping rod 331, so that the through-rod hole 322 will not jam the clamping rod 331 during the rotation of the clamping rod 331. In some other embodiments, the clamping rod and the hinge seat can be hinged directly through the rotating shaft, and the rotating shaft can also be quickly released by using a quick release pin.

[0041] In addition, the operating table 312 is fixed with a bottom cylinder 341 at a position below the upper pressing module 342, and the upper pressing module 342 is installed on the bottom cylinder 341. Further, a second limiting assembly is provided on the top of the upper pressing module 342 to keep the clamping rod 331 above the upper pressing module 342. The second limiting assembly includes two second limiting columns 343 fixed to the upper pressing module 342, the two second limiting columns 343 are respectively located on the left and right sides of the upper pressing module 342, and the clamping rod 331 is located between the two second limiting columns 343, so that the horizontal position of the clamping rod 331 is limited by the two second limiting columns 343. It can be understood that when the clamping rod 331 is rotated and pressed downward, the clamping rod 331 drives the upper pressed module 342 downward. The bottom cylinder 341 acts as a buffer cylinder. On the one hand, it keeps the direction of the upper pressed module 342 downward, that is, it moves downward along the axial direction of the piston rod of the bottom cylinder 341. On the other hand, it can provide a reverse force to facilitate the control of the downward speed of the upper pressed module 342. Since the clamping rod 331 is rotated and pressed downward, rather than moving vertically downward, the clamping rod 331 will have a displacement change after contacting the upper pressed module 342. In this embodiment, the clamping rod 331 is not directly connected to the upper pressed module 342, which can prevent interference. At the same time, the clamping rod 331 is horizontally limited by the second limiting columns 343 on the left and right sides, which can prevent the clamping rod 331 from shaking left and right when operating the clamping rod 331. The left and right positions of the front end of the clamping rod 331 are also limited by the side walls on both sides of the rod through hole 322, so that the clamping rod is very stable when pressed downward.

[0042] In addition, the sum of the diameter of the clamping rod 331 and the height of the first limiting column 332 is smaller than the height of the rod-penetrating hole 322. When the clamping rod 331 is hinged to the hinge seat 321, the front end of the clamping rod 331 can be passed through the rod-penetrating hole 322, and the middle of the clamping rod 331 is placed between the two second limiting columns 343 of the upper compression module 342. The rear section of the clamping rod 331 is pressed downward, and the upper compression module 342 is used as the fulcrum of the clamping rod 331. The front end of the clamping rod 331 is limited by the side wall on the upper side of the rod-penetrating hole 322, and the two first limiting columns 332 limit the front and rear positions of the clamping rod 331. Therefore, the clamping rod 331 will not be separated from the rod-penetrating hole 322. Of course, the clamping rod 331 can be disassembled. Just lift the rear section of the clamping rod 331 to move the front end of the clamping rod 331 downward, so as to disengage from the rod through hole 322 .

[0043] The clamping rod 331 is placed between the two second limiting columns 343 and passes through the rod through hole 322 of the hinge seat 321, so that the hinge seat 321 is located between the two first limiting columns 332; then, the operator places the product 10 before edging on the pressing lower module 313. At this time, the column outer panel and the column inner panel are not wrapped together, and the column outer panel 12 of the product is placed downward. The operating table 312 is also provided with a third limiting column 314 for positioning the product 10. The operator keeps the edge of the column outer panel 12 in contact with the third limiting column 314 during the edging process; another operator presses down the rear section of the clamping rod 331, driving the pressing upper module 342 downward, so that the column outer panel 12 of the product is completely fitted with the column inner panel 11, so that the column inner panel 11 and the column outer panel 12 can be wrapped in place.

[0044] The automobile door frame pillar hemming tool of the present embodiment has a simple structure and can perform hemming on the pillar inner panels and pillar outer panels of various new vehicle prototype samples. During the production and demonstration of new vehicle prototype samples, there is no need to develop special hemming molds and packaging equipment, and the hemming quality requirements consistent with the special tooling can be achieved, which greatly saves the cost of developing new models and can significantly shorten the development verification cycle.

[0045] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
