[0040] EMBODIMENT
[0041] The present embodiment provides a linkage type rotary wedge mechanism, as shown in the accompanying drawings, comprising: a working block 1, a linkage block 2, a rotary guide block 3, a rotary sliding adapter 4, and a base 5. The base 5 provides mechanism support, the working block 1 and the linkage block 2 are interactive parts, and the rotary guide block 3 plays a sliding transmission role inside the mechanism. Figure 1
[0042] Specifically, the working block 1 and the linkage block 2 are respectively connected with the rotary guide block 3, the rotary guide block 3 is arranged on the rotary sliding adapter 4 for sliding transmission, and the rotary sliding adapter 4 is connected with the base 5. It also comprises a front cover plate 61, a left cover plate 62, a rear cover plate 63, and a right cover plate 64, which are connected with the base 5 to form a coverless box-shaped space, and each cover plate and the base 5 provide mechanism support and internal sliding guide. The working block 1 and the linkage block 2 are detachably connected with an upper turning knife block 8 at the top. In order to facilitate movement and return, the working block 1 and the linkage block 2 are each provided with an elastic component for returning the working block 1 and the linkage block 2 to the initial position. Preferably, the elastic component is a return nitrogen cylinder 10, as shown in the accompanying drawings.Figure 2 As shown.
[0043] Preferably, the linkage type rotary wedge mechanism provided by the embodiment further comprises a middle partition plate 7 arranged between the working block 1 and the linkage block 2, which ensures the movement independence of the working block 1 and the linkage block 2 and simultaneously plays a guiding and sliding role.
[0044] Preferably, in the linkage type rotary wedge mechanism provided by the embodiment, the outer wall of the working block 1 and the linkage block 2 is provided with an indicating protrusion, 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 protrusion is embedded in the sliding groove, which is used for externally displaying the movement position of the working block 1 and the linkage block 2 and simultaneously plays a movement limiting role to reduce the risk of movement misplacement.
[0045] The specific movement process of the linkage type rotary wedge mechanism provided by the embodiment will be described by way of example as follows. First, the mechanism is set to be in an initial position, as shown in Figure 3 As shown, the linkage block 2 is higher than the working block 1 at this time, and 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 rotary guide block 3 and press up the other end, while driving the horizontal guide block on one side of the working block 1 to lift up, so that the upper turning blade block 8 mounted on the working block 1 completes the upward movement process, and the bottom state is as shown in Figure 4 As shown, the downward pressing 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 sliding arc of the rotary guide block 3 and the rotary sliding fit seat 4. When one movement process is completed, the working block 1 and the linkage block 2 are simultaneously worked by the return nitrogen cylinder 10 when the upper pressing block 9 is lifted up, which provides the working block 1 with a downward force and the linkage block 2 with an upward force. When the upper pressing block 9 is completely lifted up and leaves the contact surface of the linkage block 2, the linkage type rotary wedge returns to the initial state, and at this time, the forward working is completed. The reverse working principle is consistent, and the movement process is opposite.
[0046] The embodiment adopts a special linkage structure movement mode, compared with other linkage wedges, the wedge structure is more compact, and the mechanism for automatically returning to the initial state eliminates the need for a discharging mechanism, so that the turning process of one die for two pieces can be realized; at the same time, the wedge mechanism can be customized according to the size of the actual working blade, which has a wide range of popularization, lower manufacturing and processing cost than the traditional structure, the mechanism can be recycled and reused, and the working process is stable.
[0047] The specific embodiments of the present application are described above, and through the above description, relevant personnel can make various changes and modifications without deviating from the technical idea of the present application.
