The lower part of the concave positioning slide 41 is provided with an auxiliary concave positioning block 43, and the rear end of the concave positioning slide 41 is provided with an auxiliary concave positioning feed cylinder 47; the side positioning column A44 and the side positioning column B45 are separately arranged in the reference concave -Shaped positioning block 42 on both sides; the reference concave positioning block 42 is provided with an adjusting hand wheel 48 on the tail, and the adjusting hand wheel 48 is provided with a digital display table 49; the concave positioning and side positioning integrated mechanism 4 Both sides are provided with a group corner knife A and a group corner knife B respectively. The group corner knife A and the group corner knife B are respectively connected to the group corner cylinder A and the group corner cylinder B. The group corner cylinder A, The angle forming cylinder B is fixedly installed on the forming angle platen; the end of the forming angle forming cylinder A and the forming angle forming cylinder B are equipped with cylinder adjusting handles.
[0028] The convex positioning mechanism 5 includes a convex positioning support frame 51, a convex positioning linear guide 52, a convex positioning sliding block 53, a convex positioning mounting slide 54, a convex positioning block 55, and a convex positioning lifting cylinder. 56. The convex positioning lift guide shaft 57, the convex positioning linear guide 52 is installed on the base plate 1, the convex positioning slider 53 is provided on the convex positioning linear guide 52, and the convex positioning A convex positioning and supporting frame 51 is fixedly installed on the sliding block 53. The convex positioning and lifting guide shaft 57 is vertically installed at the bottom of the convex positioning and supporting frame 51. The convex positioning and mounting sliding seat 54 is arranged on the convex shape. Position the top of the lifting guide shaft 57, the tail of the convex positioning and mounting slide 54 is provided with a convex positioning lifting cylinder 56, and the upper part of the convex positioning and mounting slide 54 is provided with a convex positioning block 55. The positioning and supporting frame 51 is connected to a gas-liquid series cylinder 58, which is fixedly installed on the bottom plate 1 of the corner head; the tail end of the convex positioning linear guide 52 is equipped with a forming switch, the A hinged ear seat is provided on the bottom plate 1 of the corner head to support the gas-liquid tandem cylinder.
[0029] The vertical pressing mechanism 6 includes a vertical pressing cylinder 62, a vertical pressing and retreating cylinder 61, the vertical pressing and retreating cylinder 61 is installed transversely on the upper part of the concave positioning slide 41, the vertical pressing cylinder 62 is longitudinally installed at the right end of the vertical compression retraction cylinder 61.
[0030] When working, the workpiece is placed on the corner assembly plate 3, and the concave positioning and side positioning mechanism adjusts the outer corner of the workpiece. The adjustment handwheel 48 at the tail of the reference concave positioning block 42 is adjusted according to the required size. The adjusting hand wheel 48 is provided with a digital display 49, which can improve the accuracy of calibration, activate the concave positioning and feeding cylinder 47, and drive the concave positioning slide 41 to move forward along the concave positioning guide 46 while driving The auxiliary concave positioning block 43 arranged at the lower part of the concave positioning slide 41 moves forward to make it correspond to the position of the reference concave positioning block 42; at this time, the reference concave positioning block 42 and the auxiliary concave positioning block 43 are aligned simultaneously The upper and lower parts of the workpiece corner are positioned to improve the accuracy of positioning. The left and right sides of the concave positioning structure are respectively provided with side positioning posts A44 and B45, which are closely attached to the two outer sides of the workpiece for positioning. The positioning efficiency is improved. The corner knives A and B, which are separately arranged on both sides of the concave positioning and side positioning integrated mechanism 4, are driven by the corner oil cylinder A and the corner oil cylinder B to tighten with the workpiece profile. The end of the angle group cylinder A and group angle cylinder B are equipped with cylinder adjustment handles; while the concave positioning and measurement are integrated structures to locate the outer corner of the workpiece, the convex positioning mechanism 5 positions the inside of the workpiece, Wherein, the convex positioning lift cylinder 56 is activated to prompt the convex positioning slide to move upward along the convex positioning lift guide shaft 57, and the gas-liquid series cylinder pushes the convex positioning support frame 51 to move along the convex positioning linear guide 52 to the specified position. , The convex positioning block 55 locates the inside of the workpiece, the concave positioning and side positioning integrated mechanism 4 and the convex positioning device cooperate to make the workpiece tightly connected laterally; the vertical pressing and retreating cylinder 61 acts to advance the vertical pressing cylinder 62 Right above the joint of the work piece, the vertical pressing cylinder 62 acts to press the work piece tightly and vertically. At this point, the precise positioning of the workpiece group angle is achieved.
[0031] When the angle grouping process is completed, each mechanism returns to the original position in reverse according to the above steps.
[0032] The embodiments are only to illustrate the technical concept and characteristics of the present invention, and their purpose is to enable those skilled in the art to understand the content of the present invention and implement them accordingly, and cannot limit the protection scope of the present invention. All equivalent changes or modifications made in accordance with the spirit of the present invention should be covered by the protection scope of the present invention.
