Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically to a flanging device for processing the rear crossbeam connecting plate of an automotive roof. Background Technology

[0002] In the automobile production process, various parts need to be assembled. There are many types of automobile parts, most of which are processed from sheet metal. When the inner panel connecting the rear crossbeam of the roof is processed, it needs to be flanged. Flanging can increase the contact area of ​​the connection and form a certain rigid structure at the connection, making the connection stronger and improving the overall rigidity. Flanging is usually achieved by stamping. The sheet metal is placed between the upper and lower dies, and pressure is applied to deform it. The design shape and size of the upper and lower dies will cause the metal material of the connection to be flipped outward, thus achieving the flanging process.

[0003] A search revealed a Chinese patent document disclosing a flanging device for processing the inner panel connecting the rear crossbeam of an automobile roof [Application No.: CN202322620899.4]. This flanging device for processing the inner panel connecting the rear crossbeam of an automobile roof includes a worktable, a column mounted on the upper surface of the worktable, a top plate mounted on the top of the column, a hydraulic rod mounted on the upper surface of the top plate, and the telescopic end of the hydraulic rod extending through to the lower side of the top plate. An upper mold and a lower mold are respectively arranged between the top plate and the worktable. A fixing block A is installed at the end of the telescopic end of the hydraulic rod and on the upper surface of the worktable. A fixing block B is installed on the side of the upper mold and the lower mold facing the fixing block A.

[0004] The device disclosed in this patent can replace the upper mold by using a positioning rod. However, after replacement, the upper mold is limited by only one positioning rod. The mold itself is heavy and the stress generated during the stamping process is also large. Limiting the upper mold by only the positioning rod can easily cause the upper mold to detach, resulting in poor fixing effect.

[0005] Meanwhile, the device cannot obstruct the movement space of the upper mold during the stamping process, which may cause accidental injury to workers if other items or workers' bodies are not removed from the movement space of the upper mold during the stamping process, thereby reducing the safety and applicability of the device.

A placement plate is fixedly connected to one side of the mounting shell, and a blocking frame is fixedly connected to the bottom of the placement plate. A protective mechanism is installed on the surface of the blocking frame.

[0010] Preferably, the positioning mechanism includes a movable rod that slides inside the support frame and a positioning plate fixed to its bottom, as well as a compression spring fixed to the top of the positioning plate and a positioning groove formed on the surface of the mounting housing.

[0013] Preferably, the connecting frame has an inclined structure design, and the connecting frame is used in conjunction with the blocking frame.

[0014] Preferably, the surface of the movable block and the cross-sectional shape of the inner cavity of the mounting shell are both T-shaped structures, and the mounting shell is used in conjunction with the movable block.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes the cooperation between the mounting shell and the movable block to achieve a large contact area. Furthermore, with the assistance of the positioning mechanism, the movable block can be further limited, thereby effectively improving the stability of the upper mold.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4As shown, a flanging device for processing the connecting plate of the rear crossbeam of an automobile roof includes a frame 1. A lower mold 2 is installed inside the frame 1. A hydraulic cylinder 3 is bolted to the top of the frame 1. The output shaft of the hydraulic cylinder 3 passes through the interior of the frame 1 and is slidably connected to the inner wall of its penetration point. A mounting shell 4 is fixedly connected to the output shaft of the hydraulic cylinder 3. A movable block 5 is slidably connected to the inner cavity of the mounting shell 4. An upper mold 6 is installed at the bottom of the movable block 5. Under this action, the upper mold 6 can be moved by the cooperation of the hydraulic cylinder 3 and the mounting shell 4, so that the lower mold 2 and the upper mold 6 cooperate to perform flanging processing on the connecting plate. The surface of the movable block 5 and the cross-sectional shape of the inner cavity of the mounting shell 4 are both T-shaped structures. The mounting shell 4 and the movable block 5 are used together. Under this action, the movable block 5 can be locked by the shape cooperation, so that the movable block 5 will not easily move out of the interior of the mounting shell 4. Moreover, the contact area is large, which effectively improves the stability of the upper mold 6 when moving. A support frame 7 is fixedly connected to one side of the top of the mounting shell 4. The support frame 7 is an L-shaped structure. The support frame 7 is installed inside the mounting shell 4. A positioning mechanism 8 is provided, which works in conjunction with the mounting shell 4. Under its function, the movable block 5 can be limited, so that the movable block 5 will not move out of the inside of the mounting shell 4. Moreover, with the cooperation of the positioning mechanism 8, it is also convenient to remove the movable block 5, so as to facilitate the replacement of the upper mold 6 by the operator. A placement plate 9 is fixedly connected to one side of the mounting shell 4, and a blocking frame 10 is fixedly connected to the bottom of the placement plate 9. The blocking frame 10 has a U-shaped structure design. The blocking frame 10 can block the upper mold 6, so that the operator's hand will not easily come into contact with the upper mold 6. This avoids accidental injury to the operator when the operator's hand is not moved out of the movement range of the upper mold 6, effectively improving the safety of the device when flipping and further improving the applicability of the device. A protective mechanism 11 is installed on the surface of the blocking frame 10. When the upper mold 6 moves downward, the protective mechanism 11 can push the items or the operator's body at the bottom of the protective mechanism 11 outward, so that the items or the operator's body will not easily come into contact with the upper mold 6, thereby improving the safety of the device during use.

[0024] The positioning mechanism 8 includes a movable rod 81, the surface of which is slidably connected to the inner wall of the support frame 7. A positioning plate 82 is fixedly connected to the bottom of the movable rod 81, and a compression spring 83 is fixedly connected to the top of the positioning plate 82. The other end of the compression spring 83 is fixedly connected to the inner wall of the support frame 7. A positioning groove 84 is formed on the surface of the mounting shell 4. The positioning groove 84 cooperates with the mounting shell 4. Under the action of the compression spring 83, the positioning plate 82 can be moved into the interior of the positioning groove 84, thereby blocking the movable block 5 and preventing the movable block 5 from easily leaving the mounting shell. When the movable block 5 needs to be removed, the operator can pull the movable rod 81 to move the positioning plate 82 out of the positioning groove 84, thereby limiting the movable block 5 and facilitating the replacement of the upper mold 6. The movable rod 81 has a T-shaped cross-section and works in conjunction with the support frame 7. Under this action, the movable rod 81 can be limited by the shape, so that it will not easily detach from the inside of the support frame 7, thus avoiding the movable rod 81 detaching from the inside of the support frame 7 and affecting the limiting effect on the movable block 5.

[0025] The protective mechanism 11 includes a connecting frame 111, the inner wall of which is rotatably connected to the surface of the blocking frame 10. One end of the connecting frame 111 is fixedly connected to a movable roller 113, and a torsion spring 112 is fixedly connected to one side of the connecting frame 111. The other end of the torsion spring 112 is fixedly connected to the surface of the blocking frame 10. Under this action, the movable roller 113 can push the object below it outwards, thereby preventing the upper mold 6 from accidentally injuring the staff when it moves. Moreover, with the help of the torsion spring 112, the connecting frame 111 can return to its original position after rotation, thus facilitating the subsequent use of the movable roller 113. The connecting frame 111 has an inclined structure design. The connecting frame 111 works in conjunction with the blocking frame 10. Under the action of the position, when the movable roller 113 squeezes the object, the connecting frame 111 can rotate outwards, thereby pushing the object away from the upper mold 6, preventing the upper mold 6 from pressing on other objects or the body of the staff when it moves downwards, thus affecting the safety of the device during use.

[0026] It is worth noting that the technical features such as frame 1, lower mold 2, hydraulic cylinder 3 and upper mold 6 proposed in this technical solution should be regarded as the technology in the comparative case. The specific structure, working principle and possible control method and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0027] Working principle: First, the connecting plate to be flanged is placed inside the lower mold 2. Then, the hydraulic cylinder 3 is activated. With the cooperation of the hydraulic cylinder 3, the upper mold 6 is moved downward through the cooperation of the mounting shell 4 and the movable block 5, thereby flanging the connecting plate. When the upper mold 6 moves, the blocking frame 10 and the protective mechanism 11 are moved downward through the placement plate 9. With the cooperation of the movable roller 113, when it moves downward, it can rotate with the cooperation of the movable roller 113 and the connecting frame 111, thereby pushing the item below the movable roller 113 away from the upper mold 6, thus improving the safety of the device. After the flanging is completed, the hydraulic cylinder 3 drives the upper mold 6 and its surface parts back to their original positions. When the upper mold 6 needs to be replaced, the operator pulls the movable rod 81 to disengage the positioning plate 82 from the inside of the positioning groove 84. Then, the operator pulls the upper mold 6 to slide the movable block 5 out from the inside of the mounting shell 4, thereby replacing the upper mold 6.
