Description

Technical Field

[0001] The present invention relates to the field of automobiles, and in particular to a linked rotating wedge mechanism. Background Art

[0002] In the field of automobile manufacturing, for the upper flanging process, the mold structure design in the existing technology mostly adopts a reverse wedge mechanism, which can realize single-sided flanging and retraction functions. If a double-structure mold design of one mold and two pieces is to be realized, two sets of reverse wedge mechanisms must be designed and placed symmetrically.

[0003] However, the existing technology has defects, and it is difficult to achieve synchronous working motion. The increase in the simultaneous installation position of the two groups will lead to an increase in the size of the mold body, which will ultimately increase the cost of mold standard parts and processing costs.

[0008] It also includes a front cover plate, a left cover plate, a rear cover plate, and a right cover plate, which are connected with the base to form a box-like space without a cover;

[0009] The tops of the working block and the linkage block are detachably connected with an upward-turning knife block;

[0010] The working block and the linkage block are both provided with elastic components for returning the working block and the linkage block to their initial positions.

[0011] Preferably, the outer walls of the working block and the linkage block are provided with indicating protrusions;

[0012] The left cover plate and the right cover plate are respectively provided with sliding grooves extending in the vertical direction and parallel to each other;

[0013] The indicating protrusion is embedded in the sliding groove to externally display the movement position of the working block and the linkage block, and plays a role in limiting the movement of the working block and the linkage block.

[0014] Preferably, the elastic component is a return nitrogen cylinder.

[0015] Preferably, it further comprises a middle partition plate, wherein the middle partition plate is arranged between the working block and the linkage block.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention adopts a special linkage structure and an automatic return mechanism design to restore the initial state, so that the structure is more compact, and by eliminating the unloading mechanism, the flipping process of one mold and two pieces can be realized.

[0040] Example

[0041] This embodiment provides a linked rotating wedge mechanism, such as Figure 1 As shown, it includes: a working block 1, a linkage block 2, a rotating guide block 3, a rotating sliding seat 4, and a base 5. The base 5 provides a supporting function for the mechanism, the working block 1 and the linkage block 2 are working interactive parts, and the rotating guide block 3 plays a role of sliding conduction inside the mechanism.

[0042] Specifically, the working block 1 and the linkage block 2 are respectively connected to the rotating guide block 3. The rotating guide block 3 is arranged on the rotating sliding seat 4 for sliding conduction. The rotating sliding seat 4 is connected to the base 5. It also includes a front cover plate 61, a left cover plate 62, a rear cover plate 63, and a right cover plate 64, which are connected to the base 5 to form an uncovered box-shaped space. Each cover plate and the base 5 provide mechanical support and internal sliding guide function. The top of the working block 1 and the linkage block 2 can be detachably connected to an upward turning knife block 8. In order to facilitate movement and return, the working block 1 and the linkage block 2 are both provided with an elastic component for returning the working block 1 and the linkage block 2 to their initial positions. Preferably, the elastic component is a return nitrogen cylinder 10, such as Figure 2 shown.

[0043] Preferably, the linked rotating wedge mechanism provided in this embodiment further comprises a middle partition plate 7, which is arranged between the working block 1 and the linking block 2 to ensure the independence of the movements of the working block 1 and the linking block 2 and to play a sliding guide role.

[0044] Preferably, in the linked rotary wedge mechanism provided in this embodiment, the outer walls of the working block 1 and the linking block 2 are provided with indicating protrusions, and the left cover plate 62 and the right cover plate 64 are respectively provided with sliding grooves extending in the vertical direction and parallel to each other. The indicating protrusions are embedded in the sliding grooves to externally display the movement positions of the working block 1 and the linking block 2, and at the same time play a role in movement limiting to reduce the risk of movement dislocation.

[0045] The following is an exemplary description of the specific movement process of the linked rotating wedge mechanism provided in this embodiment. First, the mechanism is set to be in the initial position, such as Figure 3 As shown, the linkage block 2 is now higher than the working block 1. When the upper pressing block 9 moves downward with the upper die, the linkage block 2 drives the horizontal guide block below to press down one end of the rotating guide block 3 and press up the other end, and at the same time drives the horizontal guide block on one side of the working block 1 to lift up, so that the upward turning knife block 8 installed on the working block 1 completes the upward movement. Figure 4 As shown, the downward pressure of the linkage block 2 and the movement of the working block 1 are completed synchronously, and the rotation center is the center point of the guide arc of the rotating guide block 3 and the rotating sliding seat 4; when a movement process is completed, when the upper pressure block 9 is lifted, the return nitrogen cylinder 10 of the working block 1 and the linkage block 2 works at the same time, giving the working block 1 a downward force and the linkage block 2 an upward force. When the upper pressure block 9 is completely lifted and leaves the contact surface of the linkage block 2, the linkage rotary wedge returns to the starting state, and the forward work is completed. The reverse working principle is the same, and the movement process is opposite.

[0046] This embodiment adopts a special linkage structure movement mode. Compared with other linkage-type inclined wedges, this inclined wedge structure is more compact, and the mechanism of automatically returning to the initial state eliminates the need for an unloading mechanism, and can realize a two-piece flipping process of one mold; at the same time, it also allows the inclined wedge mechanism to be customized according to the size of the actual working insert, has a wide range of promotion, and has lower manufacturing and processing costs than traditional structures. The mechanism can be recycled and reused, and the working process is stable.

[0047] The above describes the specific embodiments of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical concept of the present invention.
