Description

Technical Field

[0001] The utility model relates to the technical field of bending equipment, in particular to an adjustable knife combining mechanism for a bending center and the bending center. Background Art

[0002] A bending center can perform bending processing on metal sheets at various angles by using simple dies, so as to obtain metal sheets with complex shapes. In use, the sheet is generally pressed by a knife pressing mechanism, and the bending mechanism at the rear side performs bending. During the use process, the knife pressing mechanism also needs to perform knife combining according to actual work requirements to adapt to different bending ranges. After the two opposite side edges of the sheet are bent into a cross-section in the shape of a "C" structure, when the side edge between the "C"-shaped structures on both sides of the sheet is bent, the "C"-shaped structures on both sides will interfere with the movement of the pressing knife. At present, the end pressing knives are driven to move laterally by a knife retracting drive structure to avoid interference. In the actual operation process, this will affect the precision of knife combining, and since a space for lateral movement needs to be reserved, the adjustment range of knife combining will be limited.

[0021] 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.

[0022] Reference Figures 1-5 The adjustable bending center blade assembly mechanism of this utility model is illustrated in the following embodiment: like Figure 1 As shown, the adjustable bending center blade assembly mechanism of this utility model includes: a blade holder 100 and multiple pressure blades.

[0023] In this embodiment, multiple pressure knives are arranged along the first transverse direction, and the multiple pressure knives are slidably and detachably installed on the knife holder 100 along the first transverse direction. In this embodiment, the first transverse direction is defined as the left-right direction. In some other embodiments, the first transverse direction may be defined as other directions.

[0024] During use, the clamping drive structure drives the knife holder 100 to move reciprocally along the longitudinal direction to clamp and release the plate.

[0025] When using it, select the corresponding number of pressure knives and adjust the gap between the pressure knives in the left and right directions according to the bending length range of the board, so as to adjust the length range of the board being pressed.

[0026] Each pressing knife of this embodiment is provided with a locking structure 200 for locking the pressing knife. After the pressing knife is adjusted, the position of each pressing knife is locked by the locking structure 200.

[0027] Specifically, as shown in Figure 2 , the knife holder 100 of this embodiment is provided with a sliding rail 110 extending in the left-right direction. The sliding rail 110 is arranged at the bottom of the knife holder 100, and the top of the pressing knife is slidably and detachably connected to the sliding rail 110. When performing knife assembly, the pressing knife is taken out or installed in from the end of the sliding rail 110.

[0028] As shown in Figure 2 , the locking structure 200 of this embodiment includes a locking driving member 210 and a ejector rod 220. The locking driving member 210 is configured to drive the ejector rod 220 to abut against the knife holder 100, and the locking driving member 210 may adopt a driving element such as an air cylinder, an electric cylinder or a hydraulic cylinder.

[0029] Further, as shown in Figure 1 and Figure 4 , the plurality of pressing knives of this embodiment include two end pressing knives 300 and a plurality of middle pressing knives 400, wherein the plurality of middle pressing knives 400 are located between the two end pressing knives 300, and the two end pressing knives 300 are located at the left and right ends of the sliding rail 110.

[0030] As shown in Figures 3 to 5 , the lower ends of the two end pressing knives 300 are provided with pressing seats 310. One end of the pressing seat 310 close to the middle pressing knife 400 is connected with a hinge member 320 whose axis extends along the second transverse direction. In this embodiment, the second transverse direction is defined as the front-rear direction. The pressing seat 310 is hinged to the end pressing knife 300 through the hinge member 320, and the end pressing knife 300 is provided with a knife retraction driving structure 330 for driving the pressing seat 310 to swing up and down.

[0031] When bending the side edge between the "匚"-shaped structures on both sides of the plate, first the knife retraction driving structure 330 drives the pressing seat 310 to swing to retract the pressing seat 310, so as to reduce the pressing range of the two end pressing knives 300 in the first transverse direction, allowing the pressing seat 310 to avoid and enter between the "匚"-shaped structures on both sides of the plate. Then the knife retraction driving structure 330 drives the pressing seat 310 to swing and reset until the pressing seat 310 extends into the "匚"-shaped structures on both sides of the plate and presses the plate. After bending is completed, the knife retraction driving structure 330 drives the pressing seat 310 to swing and retract again, so that the pressing seat 310 can avoid and extend out of the "匚"-shaped structures on both sides of the plate.

[0032] In this utility model, the knife retraction driving structure 330 drives the pressing seat 310 to swing to realize the avoiding and knife retraction action, without the need to move the two end pressing knives 300 along the transverse direction, which will not affect the precision of knife assembly, no space for transverse movement needs to be reserved, and the adjustment range of knife assembly is expanded.

[0033] Further, as shown in Figures 3 to 5 , the pressing seat 310 of this embodiment is provided with a side pressing portion 311 and a transverse pressing portion 312 that are connected to each other, wherein the side pressing portion 311 extends in the left-right direction away from the central pressing knife 400, while the transverse pressing portion 312 extends toward the rear side. The lower end of the central pressing knife 400 is provided with a middle pressing portion 410 extending toward the rear side. The middle pressing portion 410 of this embodiment and the transverse pressing portion 312 extend together to the same straight line extending in the left-right direction. In use, the bottom surfaces of the side pressing portion 311 and the transverse pressing portion 312 are simultaneously pressed against the plate material. After the transverse pressing portions 312 at both ends and the plurality of middle pressing portions 410 press the plate material, a bending stop line extending in the left-right direction is formed, and the plate material is bent around this bending stop line. When retracting the knives, as the pressing seat 310 swings, it drives the side pressing portion 311 and the transverse pressing portion 312 to swing together in the up-down direction, reducing the length in the left-right direction, so as to avoid the "C"-shaped structures on both sides of the plate material.

[0034] The edge of the side pressing portion 311 and the edge of the transverse pressing portion 312 in this embodiment are arranged perpendicular to each other, which can make the bending of the corner position of the plate material more accurate.

[0035] The thickness of the side pressing portion 311 and the transverse pressing portion 312 in this embodiment in the up-down direction is set to gradually decrease from the end pressing knife 300 to the outer edge respectively. On the one hand, it can perform avoidance more effectively, and on the other hand, it also increases the bending angle of the plate material. The thickness of the middle pressing portion 410 is also set to gradually decrease from the central pressing knife 400 to the outer edge.

[0036] In order to bear the maximum pressure on the pressing seat 310 and improve the pressing force on the plate material, as shown in Figure 3 , the top surface of the pressing seat 310 in this embodiment is provided with an abutting portion 313. When the pressing seat 310 receives an upward reaction force from the workpiece, the abutting portion 313 abuts against the lower end surface of the end pressing knife 300, so that the bottom surface of the pressing seat 310 is flush with the bottom surface of the central pressing knife 400 to press the plate material. It can be understood that when retracting the knife, the pressing seat 310 swings downward to retract, and when resetting, it swings upward until the abutting portion 313 abuts against the lower end surface of the end pressing knife 300, at which time the bottom surface of the pressing seat 310 is flush with the bottom surface of the central pressing knife 400.

[0037] As shown in Figure 3 and Figure 5 , the knife retraction driving structure 330 of this embodiment includes a linear driving member 331, the telescopic end of the linear driving member 331 is hinged with a transmission rod 332, the end pressing knife 300 is provided with a connecting shaft 333 arranged eccentrically with the hinge member 320, and the end of the transmission rod 332 away from the linear driving member 331 is hinged with the connecting shaft 333, wherein the linear driving member 331 can adopt driving elements such as an air cylinder, an electric cylinder or a hydraulic cylinder.

[0038] In this embodiment, the hinge 320 is located between the connecting shaft 333 and the abutment part 313. The linear drive member 331 drives the side pressure part 311 and the horizontal pressure part 312 to swing downward to retract the blade.

[0039] In this embodiment, the lower end of the end pressure knife 300 is provided with a notch 340. The notch 340 is located on the side opposite to the middle pressure knife 400. The notch 340 is provided with a hinge seat 341. The end of the pressure seat 310 near the middle pressure knife 400 is provided with a notch 314. The notch 314 fits into the hinge seat 341. The hinge 320 is connected to the hinge seat 341, which makes the structure of the end pressure knife 300 more compact.

[0040] In addition, this utility model also proposes a bending center, including the above-mentioned adjustable bending center blade mechanism.
