Detailed implementation manners

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application.

[0042] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present application 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 application.

[0043] The terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise stated, the meaning of "a plurality" is two or more.

[0044] In the description of the present application, it should be noted that, unless otherwise clearly defined and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0045] An embodiment of the present application provides an automatic die-changing device, as Figures 1 to 6 shown. The automatic die-changing device provided by the present application can be applied to an equipment scenario with multiple dies. The automatic die-changing device provided by the present application includes at least two die stations. When one die station carries a die to perform operations in the operation area, the other die station is located in the area to be operated. At this time, the die at the die station in the area to be operated can be replaced according to the subsequent operation conditions. During the replacement process, the die in the operation area can continue to work without stopping the machine. It can be seen that the present application can perform die-changing operations without stopping the machine, eliminating the additional downtime for die-changing and reducing the operation assistance time.

[0046] In some embodiments, the automatic die-changing device provided by the present application can be applied to a fully automatic terminal press. A fully automatic terminal press generally includes a protective cover. The protective cover is arranged around the operation area. The protective cover has a die inlet, and the die inlet is configured to accommodate a set of dies to pass through and move to the operation area. At this time, another set of dies is located outside the space enclosed by the protective cover. The die outside the protective cover can be replaced according to the subsequent operation requirements without stopping the machine and without opening the protective cover for the die inside the protective cover. During the replacement process, the die in the operation area can continue to work without stopping the machine. It can be seen that the present application can perform die-changing operations without stopping the machine and without opening the protective cover, eliminating the auxiliary time brought by additional downtime for die-changing, opening, and closing the protective cover, and reducing the operation assistance time.

[0047] As Figures 1 to 7 shown, in some embodiments, for ease of description, a first direction X and a second direction Y extending horizontally are configured for the automatic die-changing device. The first direction X and the second direction Y intersect. Preferably, the first direction X and the second direction Y are orthogonally arranged to facilitate precise movement control of the die.

[0048] As Figure 7 shown, in some embodiments, taking the first die 1 and the second die 2 as examples, it should be noted that the present application can load not only two dies but also three, four, or other numbers of dies according to the actual engineering situation.

[0049] As Figure 1 and Figure 2As shown, in some embodiments, the automatic die-changing device includes a first cylinder 100 and a second cylinder 200. The first cylinder 100 is configured to drive the first die 1 and the second die 2 to move along the first direction X, so that the first die 1 or the second die 2 enters the area to be operated. The second cylinder 200 is configured to drive the first die 1 or the second die 2 to move along the second direction Y, so that the first die 1 or the second die 2 enters the operation area. When the equipment connected to the automatic die-changing device of the present application is working, the first cylinder 100 acts to drive the first die 1 and the second die 2 to move synchronously along the first direction X. Taking the replacement of the first die 1 as an example, the first die 1 is moved to the area to be operated, and the second die 2 is synchronously moved to the operation preparation area; the second cylinder 200 acts to push the second die 2 in the operation preparation area to the operation area along the second direction Y. When the second die 2 is operating in the operation area, the first die 1 is in the area to be operated. At this time, the first die 1 in the area to be operated can be replaced according to the subsequent operation requirements, which can avoid the time cost caused by additional downtime for die change.

[0050] As Figure 1 , Figure 2 and Figure 5 shown, in some embodiments, the automatic die-changing device further includes a third cylinder 300. The third cylinder 300 is connected to the second cylinder 200. When the second cylinder 200 acts along the second direction Y, it drives the third cylinder 300 to move along the second direction Y; the cylinder rod of the second cylinder 200 is connected to the cylinder body of the third cylinder 300. When the second cylinder 200 acts, the cylinder rod of the second cylinder 200 pushes the third cylinder 300 to move along the second direction Y, and the third cylinder 300 drives the first die 1 or the second die 2 to move along the second direction Y, realizing the movement of the first die 1 or the second die 2 towards the operation area.

[0051] As Figure 1 , Figure 2 and Figure 5As shown, in some embodiments, to connect the third cylinder 300 to the first mold 1 or the second mold 2, the automatic mold changing device further includes a first connecting member 400 and a second connecting member 500. The first connecting member 400 is connected to the piston rod of the third cylinder 300, and the second connecting member 500 is provided on both the first mold 1 and the second mold 2. When the first cylinder 100 operates, it drives the first mold 1 and the second mold 2 to operate, so that the second connecting member 500 of the first mold 1 or the second mold 2 is aligned with the first connecting member 400 along the third direction Z; then the third cylinder 300 operates, and the piston rod of the third cylinder 300 drives the first connecting member 400 to move towards the second connecting member 500, realizing the connection between the first connecting member 400 and the second connecting member 500, and establishing a transmission system of the second cylinder 200, the third cylinder 300, the first connecting member 400, the second connecting member 500, and the first mold 1 or the second mold 2 in the second direction Y, so as to drive the first mold 1 or the second mold 2 to move in the second direction Y through the operation of the second cylinder 200.

[0052] As Figures 1 to 3 shown, in some embodiments, to facilitate the loading of the first mold 1 and the second mold 2, the automatic mold changing device of the present application further includes a first carrier 600 and a second carrier 700. The first mold 1 and the second mold 2 are loaded on the first carrier 600, and the first carrier 600 is connected to the first cylinder 100.

The first carrier 600 carries the first mold 1 and the second mold 2 and moves between the working area and the preparation working area along the first direction X. The second cylinder 200 and the third cylinder 300 are both provided on the second carrier 700. After the first mold 1 or the second mold 2 moves to the preparation working area, the third cylinder 300 operates, driving the first connecting member 400 to connect with the second connecting member 500. The second cylinder 200 operates along the second direction Y, driving the first mold 1 or the second mold 2 to move between the preparation working area and the working area along the second direction Y through the third cylinder 300, the first connecting member 400, and the second connecting member 500.

[0053] As Figure 1 and Figure 2As shown, in some embodiments, the second cylinder 200 and the third cylinder 300 are located between the first carrier 600 and the second carrier 700, such that the lever of the second cylinder 200 and the cylinder block of the third cylinder 300 can be directly connected, effectively reducing the connection distance. In the present application, the automatic die-changing device is further configured with a third direction Z, and the first direction X, the second direction Y, and the third direction Z are orthogonal to each other. The cylinder rod of the third cylinder 300 is arranged along the third direction Z. At the same time, the second cylinder 200 and the third cylinder 300 are located between the first carrier 600 and the second carrier 700, which can minimize the length of the third cylinder rod. Under the same thrust acting on the third cylinder 300 along the second direction Y, the stiffness of the cylinder rod of the third cylinder 300 can be stronger and the deformation amount can be smaller, effectively improving the stability of the device when transmitting thrust.
