DETAILED DESCRIPTION

[0032] The application will be further described in detail below with reference to the accompanying drawings.

[0033] As Figures 1-2 ​​​As shown, the auxiliary device for product debugging of the bending center mainly includes a guide rail 1, a polygonal movable mechanism 2, a stop finger 3, a slide rail 6, and two motors 7. Among them, the guide rail 1 extends horizontally and is set on the C-shaped cutter 10 of the processing equipment. The C-shaped cutter 10 includes a cutter body 11, with an upper bending cutter 12 at the upper end and a lower bending cutter 13 at the lower end. The guide rail 1 is set inside the cutter body 11.

[0034] The polygonal movable mechanism 2 is slidably mounted on the guide rail 1 via a slide rail 6, and the slide rail 6 is connected to one of the motors 7. Therefore, the polygonal movable mechanism 2 can move horizontally along the guide rail 1 under the action of the motor 7. Let the length of the guide rail 1 be L1.

[0035] The polygonal movable mechanism 2 is preferably a parallelogram, consisting of four movable sides 4, with each pair of adjacent movable sides 4 connected by multiple hinges 5. One movable side 4 is slidably mounted on the guide rail 1, while a stop finger 3 is installed on the top of the opposite movable side 4. The length of the longer side of the parallelogram in the polygonal movable mechanism 2 is L2, and the length of the wider side is W2.

[0036] In addition, another motor 7 is connected to at least one hinge 5 on the polygonal moving mechanism 2, and the operation of the motor 7 can drive the polygonal moving mechanism 2 to perform deformation lifting motion with the shaft mounted on the guide rail 1 as the fixed point.

[0037] When not in use, the auxiliary device is at the zero point position of guide rail 1.

[0038] like Figure 1 As shown, when the auxiliary device is used in the bending center, the feeding device 14, the pressing device 15 and the C-shaped knife 10 are arranged in sequence. When the feeding device 14 transports the sheet 17 to be bent through the pressing device 15, the auxiliary device operates. The stop finger 3 on the polygonal moving mechanism 2 can be moved to the position that blocks the sheet 17 through the two-axis movement. The pressing device 15 and the pressing knife 16 on it can perform pressing.

[0039] like Figure 3 As shown, the process of using this auxiliary device to adjust the processing of the bending center includes several main steps, which are described below.

[0040] The first step is to start debugging.

[0041] In this step, you can enable debugging through the debugging interface. For example... Figure 4As shown, the debugging function interface will display that debugging has been enabled. In addition, the debugging function interface will also display options for entering compensation values ​​such as position compensation, rotation compensation, and angle compensation, as well as the mechanical coordinates and relative coordinates of the feeding length V and rotation angle C of the plate 17, and the temporary lifting value W of the pressing device 15.

[0042] When starting the commissioning process, after the feeding shaft feeds the material, all devices on the machine stop running, but the machine is still in the processing state without interruption. At the same time, the handwheel is enabled, allowing the operator to control the axis through the handwheel.

[0043] The second step is to begin feeding compensation, with the auxiliary device moving into position.

[0044] In this step, the feeding compensation is initiated by moving the auxiliary device until its stop finger 3 is moved to the designated position (i.e., at the same horizontal level as the sheet metal 17) for easy alignment. Let the current feeding length be U, the thickness of the sheet metal 17 be S, and the distance from the tip of the pressure knife 16 to the inner side of the C-shaped knife 10 be L. Then, the absolute coordinates of the horizontal position of the auxiliary device are:

[0045] L1\2-W2-sqrt[L22-(L-U-S)2];

[0046] At this time, the stop finger 3 rises to block the plate 17, and the distance between the auxiliary device and the edge of the pressing plane is equal to the length of this bend plus the thickness of the plate 17.

[0047] The third step is to perform the first position compensation.

[0048] In this step, the feeding shaft sends the plate 17 to the initial position, the handwheel is turned to the corresponding axis, and the plate 17 is moved to block the stop finger 3 of the auxiliary device; then, by observing the relative coordinate value, the accurate feeding shaft compensation value is determined, and the feeding shaft compensation value is written into the debugging function interface for compensation.

[0049] Here, let the feeding length, i.e. the length of the initial position coordinates relative to the origin, be V1, and the feeding axis compensation value be V2.

[0050] The fourth step is to perform rotational compensation.

[0051] In this step, dynamic compensation of the rotation axis is performed by stepping on the foot pedal. The plate 17 is positioned at the initial angle (i.e., the initial rotation angle of plate 17). The handwheel is turned to the corresponding axis, and the handwheel is cranked to make plate 17 press against the auxiliary mechanism. Then, by observing the relative coordinate values, the precise rotation axis compensation value is determined and written into the debugging function interface for compensation.

[0052] Where the initial rotation angle is C1 and the rotation axis compensation value is C2, then the actual rotation angle is:

[0053] C = C1 + C2.

[0054] The fifth step is to perform a second position compensation.

[0055] In this step, the centrifugal force generated during actual rotation may cause the feeding position to shift, so position compensation is required again. In this position compensation, the current position of plate 17 is taken as the initial position, and the process is roughly similar to the first position compensation.

[0056] Wherein, if the compensation value of the feeding shaft for this feeding is V3, then the actual feeding length is:

[0057] V = V1 + V2 + V3.

[0058] Step 6: Move the auxiliary device backward and bend it once.

[0059] In this step, the auxiliary device is moved backward by stepping on the foot pedal to reserve a bending position, wherein the backward distance is preferably 10mm. Then, the bending center is used to perform a bending process on the plate 17.

[0060] Step 7: Perform angle compensation.

[0061] In this step, the bending compensation value is determined by measurement and written into the debugging function interface for compensation.

[0062] Wherein, let the initial bending angle of sheet 17 be R1, and the bending compensation value be R2, then the actual bending angle is:

[0063] R = R1 + R2.

[0064] In addition, during the debugging process, the coordinate W of the pressing device 15 can be temporarily raised to make the pressing device 15 temporarily higher, which makes it easier to observe the bending of the sheet 17.

[0065] Step 8: Perform multiple folds until the bending angle of board 17 meets the requirements. At this point, the bending process of one side of board 17 is completed.

[0066] In this step, if the bending angle does not meet the requirements, the angle compensation from the previous step is repeated.

[0067] Step 9: Repeat steps 2 through 8 above until compensation for all bending processes on all edges of the entire sheet 17 is completed.

[0068] Finally, after compensating the entire sheet 17, the auxiliary device returned to its initial position, the debugging process ended, and the bending center was ejected.

[0069] The above descriptions are merely some embodiments of the present invention. Those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
