DETAILED DESCRIPTION OF THE EMBODIMENTS



[0014] In order to make the technical problems, the technical solutions and the beneficial effects of the present invention clearer and more intelligible, the present invention will be further elaborated in combination with accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are used only to explain the present invention rather than limit the present invention.

[0015] By referring to FIGS. 1, 2 and 3, a high-speed smart numerical control hydraulic cutting machine provided by the present invention includes a die cutter fixing plate and a die cutter A for cutting an object. A die cutter clamping and limiting device is disposed on the die cutter fixing plate 3 to clamp the die cutter. The die cutter clamping and limiting device includes a clamping assembly 1 and a limiting assembly which are mounted on the die cutter fixing plate 3.

[0016] The clamping assembly 1 includes a left die pressing plate 4, a right die pressing plate 5, and pressing cylinders 6. The left die pressing plate 4 and the right die pressing plate 5 are disposed on the left and right side edges of a lower surface of the die cutter fixing plate 3 respectively. The pressing cylinders 6 are disposed inside the die cutter fixing plate 3 and located at four corners of the die cutter fixing plate 3 in a manner of left-right and back-front symmetry. The pressing cylinders 6 drive the left die pressing plate 4 and the right die pressing plate 5 respectively to press the die cutter A closely against the lower surface of the die cutter fixing plate 3.

[0017] The limiting assembly includes front limiting components and rear limiting components located at front and rear side surfaces of the die cutter fixing plate 3, where the front limiting components 7 are movable limiting components and the rear limiting components are fixed limiting components. The front limiting components 7 perform limiting or unlocking for the front and rear side surfaces of the die cutter A in linkage with the left die pressing plate 4 or the right die pressing plate 5. As shown in FIGS. 1, 2, and 3, the front limiting components 7 are respectively disposed at the front and rear side surfaces of the die cutter fixing plate 3.

[0018] When the die cutter A is in a clamped state, the left die pressing plate 4 and the right die pressing plate 5 press the die cutter A closely against the lower surface of the die cutter fixing plate 3 along an up-down direction under the drive of the pressing cylinders 6. At this time, the limiting assembly performs limiting for the front and rear side surfaces of the die cutter A. In this way, the position repeatability and positioning accuracy of the die cutter is improved and the size accuracy of the cut products is also improved.

[0019] The limiting assembly acts in the following process: when the left die pressing plate 4 and the right die pressing plate 5 of the clamping assembly 1 press the die cutter A closely against the lower surface of the die cutter fixing plate 3, the front limiting components 7 perform limiting for the front side surface and/or rear side surface of the die cutter A immediately. On the contrary, when the left die pressing plate 4 and the right die pressing plate 5 of the clamping assembly 1 release the up-down press on the die cutter A, the front limiting components 7 release limitation for the front side surface and/or the rear side surface of the die cutter A immediately.

[0020] Two pressing cylinders 6 are disposed at the right and left sides of the die cutter fixing plate 3 respectively. The two pressing cylinders 6 act simultaneously to press or release the die cutter A.

[0021] The pressing cylinder 6 includes a cylindrical hole 61, a valve core shaft 62, an upper piston 63, a lower piston 64, an upper air chamber 65 and a lower air chamber 66, where the cylindrical hole 61 is disposed inside the die cutter fixing plate 3 and the valve core shaft 62, the upper piston 63, the lower piston 64, the upper air chamber 65 and the lower air chamber 66 are disposed inside the cylindrical hole 61. The upper piston 63 and the lower piston 64 are disposed on the valve core shaft 62 respectively. The upper air chamber 65 is disposed between the upper piston 63 and the top wall of the cylindrical hole 61. The lower air chamber 66 is disposed between the upper piston 63 and the lower piston 64. An upper air pipe connector 8 and a lower air pipe connector 9 are disposed on the die cutter fixing plate 3 respectively. The upper air pipe connector 8 and the lower air pipe connector 9 are in communication with the upper air chamber 65 and the lower air chamber 66 through an upper channel 67 and a lower channel 68 disposed in the die cutter fixing plate 3.

[0022] In the present invention, the pressing cylinders 6 are directly made inside the die cutter fixing plate 3, which simplifies the structure of the die cutter clamping and limiting device, reduces the weight of the die cutter fixing plate 3 and improves its stability.

[0023] The pressing cylinders 6 act in the following process: when high pressure air is introduced into the upper air chamber 65 via the upper air pipe connector 8, the lower air chamber 66 recovers air via the lower air pipe connector 9, and then the valve core shaft 62 is driven to move down together with the upper piston 63 and the lower piston 64 disposed thereon, and then the valve core shaft 62 pushes open the left die pressing plate 4 or the right die pressing plate 5, thereby unlocking the die cutter A. When high pressure air is introduced into the lower air chamber 66 via the lower air pipe connector 9, the upper air chamber 65 recovers air via the upper air pipe connector 8, and then the valve core shaft 62 is driven to move up for resetting together with the upper piston 63 and the lower piston 64 disposed thereon, and then the valve core shaft 62 drives the left die pressing plate 4 or the right die pressing plate 5 closely against the die cutter A.

[0024] A stop washer 69 is disposed on an inner wall of the cylindrical hole 61 to limit a movement position of the lower piston 64, so as to limit a movement position of the valve core shaft 62, thereby limiting a telescoping height of the pressing cylinder 6.

[0025] The rear limiting component includes a limiting block and a fastening bolt (not shown). The limiting block limits the movement position of the die cutter A, and the fastening bolt fixes the limiting block on a side surface of the die cutter fixing plate 3.

[0026] The front limiting component 7 includes a first connection bar 71, a second connection bar 72, a first rotary shaft 73, a second rotary shaft 74, and a third rotary shaft 75. The first rotary shaft 73 is fixed on the die cutter fixing plate 3, and the third rotary shaft 75 is fixed on the left die pressing plate 4 or the right die pressing plate 5. The first rotary shaft 73 is movable disposed in the middle of the first connection bar 71, and the second rotary shaft 74 movably connects an end of the first connection bar 71 to an end of the second connection bar 72. A blocking portion 76 is disposed on the other end of the first connection bar 71 to limit the die cutter A, and the other end of the second connection bar 72 is movably connected with the third rotary shaft 75.

[0027] As shown in FIG. 4, one segment of inclined surface or arc-shaped surface 77 is disposed on the blocking portion 76 of the first connection bar 71, and thus it is convenient to push the die cutter A back to a correct limiting position when the first connection bar 71 performs limiting for the die cutter A.

[0028] The front limiting component 7 acts in the following process: when the pressing cylinders 6 drive the left die pressing plate 4 or the right die pressing plate 5 to move down, the third rotary shaft 75 and the second connection bar 72 move down accordingly, and the second connection bar 72 also drives, via the second rotary shaft 74, an end of the first connection bar 71 to move down. Thus, the first connection bar 71 rotates around the first rotary shaft 73, so as to lift up the other end of the first connection bar 71, thus releasing the limited die cutter A. When the pressing cylinders 6 drive the left die pressing plate 4 or the right die pressing plate 5 to move up, the third rotary shaft 75 and the second connection bar 72 move up accordingly, and the second connection bar 72 drives, via the second rotary shaft 74, an end of the first connection bar 71 to move up. Thus, the first connection bar 71 rotates around the first rotary shaft 73, so as to lower the other end of the first connection bar 71, thus limiting the die cutter A.

[0029] Limiting screws 2 are disposed between the left die pressing plate 4/the right die pressing plate 5 and the die cutter fixing plate 3. The limiting screws 2 are used to adjust and limit a maximum distance between the left die pressing plate 4/the right die pressing plate 5 and the die cutter fixing plate 3.

[0030] With the clamping and limiting device of the present invention, the die cutter A can be quickly limited and clamped, thus achieving quick change of the die cutter A. Further, good position repeatability and high positioning accuracy are ensured.

[0031] Side covers 10 are also disposed on the die cutter fixing plate 3 to cover the upper air pipe connector 8 and the lower air pipe connector 9.
