[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0028] Such as Figure 1-6As shown in the figure, the automatic die for aluminum hooks of the fence includes a lower die module 1 and an upper die module 2 disposed above the lower die module 1 and capable of moving up and down relative to it. A positioning seat 11 for positioning the workpiece A to be processed is provided on the lower die module 1. A sliding bending group 3 capable of sliding relative to the lower die module 1 is provided on the lower die module 1. When the upper die module 2 moves downward relative to the lower die module 1, the upper die module 2 drives the sliding bending group 3 to slide toward the positioning seat 11 side to perform a first bending on the workpiece A on the positioning seat 11. A swinging bending group 4 capable of swinging relative to the upper die module 2 is provided on the upper die module 2. The swinging bending group 4 moves downward following the upper die module 2 and swings toward the positioning seat 11 side after abutting against the lower die module 1 to perform a second bending on the workpiece A after the first bending.

[0029] This application provides an automatic die for aluminum hooks of the fence, including an upper die module and a lower die module that can move relative to each other up and down, as well as a sliding bending group and a swinging bending group disposed between the two. During the downward movement of the upper die module, the upper die module drives the sliding bending group to perform a first bending on the workpiece to be processed. The swinging bending group moves downward following the upper die module and swings toward the workpiece to be processed side after abutting against the lower die module to perform a second bending on the workpiece to be processed after the first bending, realizing the sequential bending and forming of the workpiece to be processed in one processing, and improving the high efficiency and automatic production of the aluminum hook workpiece for the fence.

[0030] Further, a sliding groove 10 extending toward the positioning seat 11 side is provided on the lower die module 1. The sliding bending group 3 includes a slider member 31 slidably disposed above the sliding groove 10. A sliding bending portion 32 is provided on the slider member 31 close to the positioning seat 11 side. When the sliding bending group 3 slides toward the positioning seat 11 side, the sliding bending portion 32 abuts against the workpiece A to be processed and drives it to bend toward the swinging bending group 4 direction. In a specific embodiment of this application, the slider member 31 is limited within the sliding groove 10. When the upper die module moves downward, it drives the slider member 31 to slide along the sliding groove 10 and approach the workpiece A to be processed on the positioning seat 11, and drives the workpiece A to be processed to perform a first bending through the sliding bending portion 32.

[0031] Still further, a forming inclined wedge 21 extending toward the lower die module 1 direction is provided on the upper die module 2. A sliding inclined surface 310 matched with the inclined surface of the forming inclined wedge 21 is provided on the slider member 31. When the upper die module 2 moves downward, the forming inclined wedge 21 drives the slider member 31 to slide through the inclined surface cooperation. Through the inclined surface cooperation, the forming inclined wedge drives the slider member 31 to move and approach the workpiece A to be processed to drive the bending of the workpiece to be processed.

[0032] Even further, the sliding bending portion 32 is a roller rotatably disposed on the slider member 31. This design is more conducive to bending the workpiece to be processed, increasing the flexible contact, and improving the processing efficiency and accuracy.

[0033] Further, a hinge seat 22 is provided on the lower side of the upper die set 2; the swing bending group 4 includes a swing member 41 hinged to the lower side of the hinge seat 22. A swing bending portion 42 is provided on the swing member 41 close to the positioning seat 11 side. When the swing bending group 4 swings towards the positioning seat 11 side, the swing bending portion 42 abuts against the workpiece A to be processed and drives the end portion thereof to be bent. In a specific embodiment of the present application, the swing member 41 is hinged to the hinge seat 22. When the upper die set moves downward, the swing member 41 is driven to move downward synchronously. When the swing member 41 contacts the lower die set, it swings towards the workpiece to be processed around the hinge, and the swing bending portion 42 drives the workpiece A to be processed to be bent again.

[0034] Furthermore, a forming arc seat 12 is provided on the lower die set 1 below the swing member 41. The surface of the forming arc seat 12 facing the positioning seat 11 is an arc-shaped concave surface. A swing arc surface 410 that matches the arc surface of the forming arc seat 12 is provided on the lower end of the swing member 41 away from the positioning seat 11 side. When the upper die set 2 moves downward, the forming arc seat 12 drives the swing member 41 to swing through arc surface matching. Through arc surface matching, the forming arc seat 12 drives the swing member 41 to swing and approach the workpiece A to be processed, so as to drive the bending of the workpiece to be processed.

[0035] Still further, the swing bending portion 42 is a roller rotatably provided on the swing member 41. This design is more conducive to bending the workpiece to be processed, increasing flexible contact, and improving processing efficiency and accuracy.

[0036] Further, a cutting female die 13 is provided on the lower die set 1 in front of the positioning seat 11. The workpiece A to be processed sequentially passes through the cutting female die 13 and the positioning seat 11. When the upper die set 2 moves downward, it drives the cutting female die 13 to move relative to the positioning seat 11 to cut the workpiece A to be processed between the cutting female die 13 and the positioning seat 11. A positioning sleeve hole 110 is formed on the positioning seat 11, and a cutting sleeve hole 130 coaxial with the positioning sleeve hole 110 is formed on the cutting female die 13. The workpiece A to be processed sequentially passes through the cutting sleeve hole 130 and the positioning sleeve hole 11. During processing, the workpiece A to be processed enters the mold through the conveying device. After being conveyed to the positioning seat 11, when the upper die set moves downward and drives the cutting female die 13 to press down, the cutting edge on the cutting female die 13 cuts the workpiece A to be processed to form a workpiece A to be processed with appropriate dimensions. Preferably, an installation groove is provided on the lower die set 1, the cutting female die 13 is limited in the installation groove, and a return spring is provided between the cutting female die 13 and the installation groove. In the initial state, the cutting female die 13 is limited in the installation groove to keep the cutting sleeve hole 130 and the positioning sleeve hole 11 at the same level. When the upper die set 2 moves downward, it drives the cutting female die 13 to move into the installation groove. When the upper die set 2 moves upward, the cutting female die 13 resets to make the cutting sleeve hole 130 and the positioning sleeve hole 11 at the same level.

[0037] Further, a plurality of guiding structures for vertical guiding are provided between the lower die set 1 and the upper die set 2. The guiding structure includes a guide sleeve 14 provided on the lower die set 1 and a guide post 23 extending downward from the upper die set 2 into the guide sleeve 14 for guiding to improve the processing efficiency of the product.

[0038] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and deformations can be made, and these improvements and deformations are also regarded as the protection scope of the present invention.
