[0030] Please see Figures 1-8 In this embodiment of the present invention, an automated tool magazine for bending centers includes a frame assembly 1 consisting of a frame body 101 and a large central rail 102, and a standard pressure knife 2.

The mold tool body 401 is sleeved on the outside of the side T-shaped hanging posts 302 through the hanging hole 403 to realize the hanging operation of the mold tool body 401.

[0035] The second moving slot 303 has a front end surface of the tool holder body 301. The second moving slot 303 is used for inserting the end of the hinge knife electric gripper 602 to facilitate the overall movement of the tool magazine tool holder 3.

[0036] The hinge blade 5 includes a hinge blade body 501, a transfer insert 502, and a gripping straight slot 503;

[0037] Two transfer pins 502 are provided. The two transfer pins 502 are vertically distributed and fixed on one side of the hinge knife body 501. The gripping straight slot 503 is opened on the front surface of the transfer pin 502. The gripping straight slot 503 is used for the end of the hinge knife electric gripper 602 to be inserted to realize the gripping operation of the hinge knife 5.

[0038] The transfer pin 502 is inserted into the inner side of the transfer hole 402 on the mold cutter body 401 to realize the transfer operation of the non-standard pressure knife 4;

[0039] The standard pressure knife 2 includes a pressure knife body 201, a positioning slot 202, and a first moving slot 203;

[0040] The pressure knife body 201 slide is connected to the large-size rail 102 in the middle. There are two positioning slots 202. The two positioning slots 202 are vertically distributed on one side of the pressure knife body 201 and extend to the other side. When the non-standard pressure knife 4 is transferred to the side of the standard pressure knife 2, the transfer pin 502 is inserted into the positioning slot 202 to realize the mutual positioning of the non-standard pressure knife 4 and the standard pressure knife 2.

[0041] The first movable slot 203 is located at the front end of the pressure knife body 201, and is used for inserting the end of the hinge knife electric gripper 602 to realize the movement operation of the pressure knife body 201.

[0042] In this embodiment, the operating principle of this combined blade magazine is as follows:

[0043] The standard mold consists of multiple standard pressure knives 2 on the large central track 102, while the non-standard mold library consists of multiple tool magazine holders 3 on the small side track 103 and non-standard pressure knives 4 of different thicknesses on the tool magazine holders 3. When bending plates of different lengths, the non-standard pressure knives 4 of different thicknesses can be transferred to the large central track 102 by the pick-and-place component 6, so as to match the plates of different lengths with the standard mold.

[0044] The XYZ three-axis drive device 601 can realize the linear motion of the three axes of the hinge knife gripper 9. The hinge knife gripper 9 has two gripping heads at one end facing the frame body 101. The hinge knife gripper 9 can be inserted into the first moving slot 203 on the standard pressure knife 2 through the two gripping heads, so as to perform horizontal moving operation on the standard pressure knife 2. Alternatively, the two gripping heads can be inserted into the second moving slot 303 on the tool magazine holder 3 to move the tool magazine holder 3, so as to perform moving operation on the non-standard pressure knife 4 of different thicknesses.

[0045] The hinge knife gripper 9 moves the hinge knife 5 to a designated position by inserting two gripping heads into the gripping slot 503 on the hinge knife 5. After the hinge knife 5 is inserted into the transfer hole 402 on the non-standard pressure knife 4 through the transfer insert 502, the XYZ three-axis drive device 601 moves the hinge knife 5 and the non-standard pressure knife 4 upwards a short distance, thereby releasing the hooking state between the hanging hole 403 and the side T-shaped hanging post 302. Then, the hinge knife 5 and the non-standard pressure knife 4 are moved away from the knife magazine holder 3, thus separating the non-standard pressure knife 4 from the knife magazine holder 3. (It should be noted that the height of the gripping slot 503 is greater than the height of the two gripping heads of the hinge knife gripper 602. After the two gripping heads of the hinge knife gripper 602 are inserted into the gripping slot 503, the hinge knife gripper 602 moves away from each other and spreads out, pressing against the upper and lower ends of the gripping slot 503 respectively, thus gripping the hinge knife 5.)

[0046] Finally, the XYZ three-axis drive device 601 pushes the non-standard pressure knife 4 onto the outside of the large-size rail groove 102 in the middle, combining it with the standard pressure knife 2 to form a combination of knives of different lengths. The overall structure is simple, compact, easy to process and manufacture, does not increase costs, is reliable, and has high precision.

[0047] Please refer to this carefully. Figures 1-4 Two sets of horizontal limit rails 104, toothed rails 105, and pick-and-place components 6 are symmetrically arranged with the center line of the main frame 101 as the center.

[0048] In this embodiment, the two sets of pick-and-place components 6 can respectively pick up and place the non-standard pressing knives 4 in the two non-standard mold libraries on both sides, resulting in higher work efficiency.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
