Description

Technical Field

[0001] The utility model relates to a multi-functional positioning device for hemming of sheet metal parts, and also relates to a sheet metal part hemming pressing device including the multi-functional positioning device, belonging to the technical field of sheet metal processing. Background Art

[0002] The sheet metal part hemming pressing device is a key device specifically used for the hemming forming of sheet metal parts, and it is also applicable to processing procedures such as bending and punching. The device generally includes components such as an upper die, a lower die, a blank holding die, and an electrical control system. It completes the hemming and pressing work of sheet metal parts in an automated manner, not only improving production efficiency and product quality, but also helping to reduce production costs. However, the existing sheet metal part hemming pressing devices usually can only process specific specifications. Once the specifications of the sheet metal parts to be processed change, these devices often cannot be simply adjusted to adapt to the new specifications, which limits their applicability and flexibility.

[0003] For example, in the Chinese utility model with the patent number ZL 201420065193.4, a vertical automatic bending device is disclosed. The device consists of a whole machine positioning bracket, a punch and a clamping device, a three-dimensional movable limiting device, a die and a buffer device, a five-axis positioning power transmission device, and an electrical and operation control system. The whole machine positioning bracket is used to determine the specific position of the device, and its four feet are equipped with rotatable leveling nuts and sucker shock absorption buffer seat pads. The punch is made of special alloy steel, and the clamping device is used to fix the pre-processed product to ensure processing accuracy. The three-dimensional movable limiting device matches the convex and concave dies and can fix the same kind of processed product in the XYZ three-axis directions. When replacing different kinds of processed products, the XYZ three axes can all move and re-adjust relevant parameters to fix the limit value.

[0004] Although the above device can be adjusted in three linear directions of XYZ, it cannot realize the rotational adjustment of the whole machine positioning bracket, nor can it specifically adjust the size of the positioning bracket according to different product sizes. These limitations mean that the application scenario of the device is still restricted to a certain extent and cannot meet diverse usage requirements. Summary of the Invention

[0034] The technical content of the present invention will be described in detail below in conjunction with the drawings and specific embodiments.

[0035] The embodiment of the present utility model first provides a multifunctional positioning device for hemming sheet metal parts. According to the actual use requirements of sheet metal hemming, it can rotate and can also stretch and press, and can conveniently adjust the pressure magnitude. In addition, it can also adaptively adjust the positioning dimensions according to sheet metal parts of different specifications to meet diverse use requirements.

[0036] As Figure 1 shown, a multifunctional positioning device for hemming sheet metal parts provided by the embodiment of the present utility model at least includes a cam divider 1, a rotating flange shaft 2, a cylinder 3, a rotating fixing plate 4, a plurality of guide posts 5, a positioning plate 6, and a plurality of auxiliary positioning members 7.

[0037] Among them, the positioning plate 6 is arranged at the bottom of the multifunctional positioning device, the top surface is connected to the guide posts 5, and an electromagnet 61 is arranged along the periphery of the top surface for fixing the object to be processed (for example: sheet metal parts). The guide posts 5 are of a telescopic structure, one end is connected to the positioning plate 6, and the other end is connected to the rotating fixing plate 4. A through hole is formed in the middle of the rotating fixing plate 4, and the top of the through hole is fixedly connected to the rotating flange shaft 2 correspondingly. The rotating flange shaft 2 is of a hollow structure and has a hollow inner cavity with openings at both ends. The bottom of the hollow inner cavity is connected to the rotating fixing plate 4, and the top is connected to the overall fixing plate 8. A through hole is formed in the middle of the overall fixing plate 8, and the bottom of the through hole is rotatably connected to the top of the rotating flange shaft 2 correspondingly, and the cam divider 1 is arranged at the top. The cam divider 1 is arranged at the top of the overall fixing plate 8 and the bottom is connected to the cylinder 3. The cylinder 3 is sleeved inside the rotating flange shaft 2, one end of the cylinder head is connected to the cam divider 1, and one end of the cylinder shaft is connected to the positioning plate 6. The up-and-down through channel formed by the overall fixing plate 8, the rotating flange shaft 2, and the rotating fixing plate 4 enables the cylinder shaft of the cylinder 3 arranged inside the rotating flange shaft 2 to perform vertical telescopic movement, thereby driving the positioning plate 6 to move up and down, achieving the effect of adjusting the up-and-down position of the object to be processed. At the same time, the cam divider 1 arranged at the top of the cylinder 3 can drive the cylinder 3 to rotate left and right, achieving the effect of adjusting the processing angle of the object to be processed.

[0038] Moreover, in this embodiment, a plurality of auxiliary positioning members 7 are further arranged around the surface of the positioning plate 6, and each auxiliary positioning member 7 is movably arranged on the surface of the positioning plate 6 to cooperate with the positioning plate 6 to jointly adjust the positioning dimensions. Preferably, as Figure 2 shown, the positioning plate 6 is a rectangular plate (not limited to this shape), and each side of the rectangular plate is provided with an auxiliary positioning member 7, and each auxiliary positioning member 7 is independently controlled. Among them, each auxiliary positioning member 7 is respectively arranged on the surface of the positioning plate 6 so as to be telescopically movable along a direction parallel to the positioning plate, thereby cooperating with the positioning plate 6 to jointly adjust the positioning dimensions.

[0039] Specifically, as Figure 2As shown, the auxiliary positioning member 7 includes an auxiliary cylinder 71 and an auxiliary positioning plate 72. Among them, the auxiliary cylinder 71 is disposed on the surface of the positioning plate 6, and the cylinder shaft of the auxiliary cylinder 71 can telescopically move in a direction parallel to the surface of the positioning plate 6. Correspondingly, the auxiliary positioning plate 72 is connected to the cylinder shaft of the auxiliary cylinder 71 to move along with the movement of the cylinder shaft of the auxiliary cylinder 71. It can be understood that when the size of the workpiece to be processed is large, the workpiece to be processed cannot be stably positioned and fixed only by the positioning plate 6. At this time, each auxiliary cylinder 71 drives each auxiliary positioning plate 72 to extend toward the outside of the positioning plate 6 respectively, so as to increase the overall size, and the auxiliary positioning plate 72 and the positioning plate 6 are used together to position the workpiece to be processed, thereby ensuring the stability of positioning.

[0040] In addition, in the above embodiment, preferably, each auxiliary positioning plate 72 corresponds to two auxiliary cylinders 71, and the two auxiliary cylinders 71 move synchronously. Thus, the stability of the auxiliary positioning plate 72 can be improved, and the positioning accuracy can be prevented from being affected by the shaking of the auxiliary positioning plate 72. It can be understood that the number of the auxiliary cylinders 71 is not limited to 2, and can also be 3 or more, and can be adaptively set according to needs.

[0041] In the above embodiment, preferably, the stroke of the auxiliary cylinder 71 is adjustable. Thus, the stroke distance of the auxiliary cylinder 71 can be adjusted according to needs to adapt to different usage scenarios and improve the convenience of positioning.

[0042] In addition, in another embodiment, each auxiliary positioning member 7 can also be rotatably disposed on the surface of the positioning plate 6 to jointly adjust the positioning size with the positioning plate 6. Specifically, in this embodiment, the auxiliary cylinder 71 is replaced with a rotary motor 71, and the auxiliary positioning plate 72 is connected to the rotary motor 71 so that the rotary motor 71 can drive the auxiliary positioning plate 72 to rotate or turn over, and then jointly adjust the positioning size with the positioning plate 6. The specific connection structure between the auxiliary positioning plate 72 and the rotary motor 71 is not limited herein and can be adaptively set according to needs.

[0043] Such as Figure 3As shown in the figure, on the basis of the above embodiments, the embodiments of the present invention further provide a hemming pressing device for sheet metal parts. In addition to the above multi-functional positioning device 10, the hemming pressing device for sheet metal parts may further include structural parts such as a base 20, a support frame 30, and a hemming structure 40. Among them, a slide rail 201 is provided on the base 20, and the support frame 30 is fixed on the base 20; the positioning mechanism is located on the support frame 30 and can move relative to the support frame 30 in the horizontal and vertical directions; the hemming mechanism 30 is fixed on the slide rail 201 and includes a plurality of pressing wheels, and the pressing wheels are arranged along the traveling direction of the workpiece to be processed, and each pressing wheel has the same linear velocity at the position where it contacts the workpiece to be processed. Thus, the hemming pressing device for sheet metal parts can press hemmings of various specifications, and can be continuously pressed, with high processing quality, so the equipment cost is reduced and the production efficiency is improved.

[0044] In summary, the multi-functional positioning device for hemming sheet metal parts and the hemming pressing device for sheet metal parts provided by the embodiments of the present invention have the following beneficial effects:

[0045] (1) It integrates multiple functions. According to the actual use requirements of sheet metal hemming, it can rotate and can also stretch and press, and can conveniently adjust the pressure, with strong practicability;

[0046] (2) Each auxiliary positioning member 7 is respectively arranged on the surface of the positioning plate 6 so as to be telescopically movable along a direction parallel to the positioning plate, so as to cooperate with the positioning plate 6 to jointly adjust the positioning size, so that the positioning size can be adaptively adjusted according to different specifications of sheet metal parts to meet diverse use requirements;

[0047] (3) By hollowing out the axis of the rotating flange shaft 2 to form a hollow cavity and placing the cylinder therein, multiple functions are realized in a limited space, and the space utilization efficiency is improved.

[0048] It should be noted that the above multiple embodiments are only examples. The technical solutions of each embodiment can be combined and are all within the protection scope of the present invention.

[0049] It should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "horizontal", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0050] In addition, the terms "first" and "second" are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.
