[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.

[0021] Reference Figures 1-6 The automatic blade-joining mechanism at the bending center of this utility model is illustrated in the following embodiment: like Figure 1 As shown, the automatic bending center blade assembly mechanism of this utility model includes: a pressure beam seat 100, a pressure blade 200, an adjustment component 300, and a locking component 400.

[0022] In this embodiment, the pressure beam seat 100 extends in the left-right direction. In use, the pressure beam seat 100 is connected to the pressing drive mechanism. The pressing drive mechanism drives the pressure beam seat 100 to press and release the plate.

[0023] like Figure 1As shown, this embodiment has multiple pressing knives 200 arranged along a first direction. In this embodiment, the first direction is defined as the left-right direction. In some other embodiments, the first direction may be other directions.

[0024] In this embodiment, multiple pressing knives 200 are slidably connected to the pressing beam seat 100 in the left-right direction. The multiple pressing knives 200 are installed side-by-side on the bottom side of the multiple pressing knives 200, as shown below. Figure 1 and Figure 2 As shown, in this embodiment, a track 110 extending in the left-right direction is provided at the bottom of the pressure beam seat 100, and a sliding groove 210 that slides with the track 110 at the upper end of the pressure knife 200.

[0025] like Figure 3 , Figure 4 and Figure 5 As shown, the adjustment assembly 300 in this embodiment includes multiple connecting clutch modules 310, a movable adjustment member 320, and an adjustment drive structure 330. The movable adjustment member 320 is slidably mounted on the pressure beam seat 100 in the left-right direction. The adjustment drive structure 330 drives the movable adjustment member 320 to reciprocate relative to the pressure beam seat 100 in the left-right direction. The multiple connecting clutch modules 310 are correspondingly mounted on multiple pressure knives 200. The connecting clutch modules 310 control the connection and disconnection between the movable adjustment member 320 and the pressure knives 200. When adjusting the position of each pressure knife, the moving adjustment component 320 is connected to the pressure knife 200 by connecting the clutch module 310. Then, the driving structure is adjusted to drive the moving adjustment component to move back and forth relative to the pressure beam seat in the first direction to the set position. After that, the moving adjustment component 320 is disconnected from the pressure knife 200 by connecting the clutch module 310.

[0026] like Figure 4 As shown, the movable adjustment member 320 of this embodiment is provided with a plurality of locking parts 321 arranged at intervals in the left and right direction. The connecting clutch module 310 is used to connect and disconnect with the locking parts 321 to control the connection and disconnection between the movable adjustment member 320 and the pressure knife 200.

[0027] When adjusting the left and right positions of each pressure knife 200, the connecting clutch module 310 on the pressure knife 200 is connected to the locking part 321. Then, the drive structure 330 is adjusted to drive the moving adjustment member 320 to move back and forth in the left and right direction relative to the pressure beam seat 100. After the pressure knife 200 moves a certain distance, the connecting clutch module 310 is separated from the old locking part 321, and the connecting clutch module 310 is connected to the next locking part 321. The moving adjustment member 320 then drives the pressure knife 200 to continue moving, moving the pressure knife 200 to the set position. This process is repeated to adjust and move each pressure knife 200 to the set position, so as to realize the individual adjustment and movement of each pressure knife 200, and reduce the amplitude of the reciprocating movement of the moving adjustment member 320, making the overall size of the equipment compact.

[0028] like Figure 5 and Figure 6 As shown, the locking assembly 400 of this embodiment includes a plurality of locking members 410 and a locking drive module. The plurality of locking members 410 are arranged at intervals along the left and right direction on the pressure beam seat 100. The locking members 410 are used to abut against the pressure knife 200. The locking drive module is used to drive the plurality of locking members 410 to move relative to the pressure beam seat 100 along the second direction to lock and release the plurality of pressure knives 200. The second direction is intersected with the first direction. In this embodiment, the second direction is defined as the front-back direction. In some other embodiments, the second direction may be a front-back tilting direction or a vertical direction.

[0029] After adjusting the position of each pressure knife 200, the locking drive module drives multiple locking parts 410 to move synchronously to lock each pressure knife 200. The arrangement distance of the multiple locking parts 410 is as small as possible to ensure that each pressure knife 200 is locked by at least one locking part 410. Thus, this utility model can automatically adjust and move multiple pressure knives 200 individually and automatically lock them at any position.

[0030] Furthermore, when two adjacent pressure knives 200 are in close contact, the distance between two adjacent connecting clutch modules 310 is equal to the distance between two adjacent locking parts 321. This ensures that the connecting clutch module 310 can connect and disengage with the two adjacent locking parts 321 while minimizing the reciprocating movement amplitude of the moving adjustment member 320. At this time, the distance of the reciprocating movement of the moving adjustment member 320 in the left-right direction can be equal to the distance between the two adjacent locking parts 321.

[0031] like Figure 4As shown, the connection clutch module 310 of this embodiment includes a clutch drive component 311 and a pin 312. The locking part 321 is a pin hole. The clutch drive component 311 is used to drive the pin 312 to connect and separate from the pin hole. The connection clutch module 310 of this embodiment is a cylinder. The connection clutch module 310 is installed in the upper end of the pressure knife 200. The clutch drive component 311 drives the pin 312 to move up and down.

[0032] In some other embodiments, the clutch module 310 may be locked and disengaged from the movable adjustment member 320 by magnetic attraction.

[0033] like Figure 3 and Figure 5 As shown, the movable adjustment member 320 in this embodiment is a rack structure extending in the left and right direction. The adjustment drive structure 330 includes a gear 331 and a rotary drive member 332. The rotary drive member 332 is connected to the gear 331 in a transmission manner. The gear 331 meshes with the rack structure. The gear 331 is rotatably mounted at the end of the pressure beam seat 100 and is located above the movable adjustment member 320. The teeth of the movable adjustment member 320 are located on the top surface.

[0034] Furthermore, such as Figure 5 and Figure 6 As shown, the locking drive module of this embodiment includes an airbag 420 extending in the left-right direction and an inflation / deflation device (not shown) connected to the airbag 420. The airbag 420 is connected to a plurality of locking members 410. The airbag 420 is used to drive the plurality of locking members 410 to abut against the pressure knife 200 by inflating, and to drive the plurality of locking members 410 to separate from the pressure knife 200 by deflation. An air nozzle 421 connected to the inflation / deflation device is provided at the end of the airbag 420.

[0035] like Figure 6 As shown, the pressure beam seat 100 of this embodiment is provided with a first mounting groove 120 extending in the left-right direction. The airbag 420 is installed in the first mounting groove 120. One side wall of the first mounting groove 120 is provided with a plurality of guide holes 121 penetrating in the front-back direction. A plurality of locking members 410 are slidably installed in the plurality of guide holes 121. The locking member 410 is a top rod structure.

[0036] Furthermore, such as Figure 2 and Figure 3 As shown, the pressure beam seat 100 is provided with a second mounting groove 130 extending in the left and right direction, and the movable adjustment component 320 is slidably installed in the second mounting groove 130.

[0037] like Figure 1 and Figure 3As shown, in this embodiment, the first mounting groove 120 and the second mounting groove 130 are arranged parallel to each other on the bottom surface of the pressure beam seat 100. The opening of the first mounting groove 120 is equipped with a cover plate 122 extending in the left and right direction. The cover plate 122 extends to the second mounting groove 130 from the side of the second mounting groove 130. The inner wall of the second mounting groove 130 away from the first mounting groove 120 is provided with a slide rail 131 extending in the left and right direction. The front and rear side walls of the movable adjustment member 320 are provided with guide grooves 322. The two guide grooves 322 slide and cooperate with the sides of the slide rail 131 and the cover plate 122 respectively, which facilitates installation and further reduces the volume.

[0038] This utility model also proposes an automatic blade-assembly method for bending centers, applicable to the aforementioned automatic blade-assembly mechanism for bending centers, such as... Figure 7 As shown, the automatic tool alignment method at the bending center includes: Step S100: Based on the bending length and shape of the sheet material to be bent, determine the number and spacing of the pressure knives 200; Step S200: Control the locking drive module to drive the locking component 410 to release all the pressing blades 200; Step S300: When adjusting the position of each pressure knife 200, the connection clutch module 310 of the pressure knife 200 is connected to its corresponding locking part 321. Step S400: Control the moving adjustment component 320 to reciprocate relative to the pressure beam seat 100 in the first direction according to the number and arrangement spacing of the pressure knives 200, so as to drive each pressure knives 200 to move to the preset position; Step S500: Control the locking drive module to drive multiple locking parts 410 to move synchronously to lock each pressure knife 200.

[0039] In step S200, the airbag 420 is deflated and contracted to cause multiple locking parts 410 to separate from the pressure knife 200.

[0040] In step S300, the clutch drive component 311 drives the pin 312 to connect and separate from the pin hole.

[0041] In step S400, after the moving adjustment member 320 drives the pressure knife 200 to move a set distance, the clutch drive member 311 drives the pin 312 to separate from the old pin hole. Then the moving adjustment member 320 moves back, and the adjacent pin hole is opposite to the pin 312. Then the pin 312 is driven to connect with the pin hole. The moving adjustment member 320 continues to drive the pressure knife 200 to move. This is repeated to drive the pressure knife 200 to the set position. When adjusting the position of the pressure knife 200, the adjustment is started from the pressure knife 200 at the end. In this way, each pressure knife 200 is adjusted to move to the preset position to form the preset knife-jointing shape.

[0042] In step S500, the airbag 420 is inflated to cause multiple locking parts 410 to abut against the pressure knife 200.

[0043] In addition, this utility model also proposes a bending center, including the aforementioned automatic blade assembly mechanism for the bending center.
