[0002] With the development of the aviation industry, the shapes of the clamps used in aircraft engines are becoming more and more complex, and the sizes are getting larger and larger. For the existing parts with larger design sizes and one end being U-shaped, the use of ordinary bending molds will cause interference between the parts and the bending machine. If stamping is used, due to the particularity of the materials used in aviation parts, there will be rebound during stamping, and the mold is large, there are certain safety risks during transportation and upper and lower molds. Therefore, in order to ensure quality and safety in existing processing, manual hammering is often required when forming the U shape, but this will lead to unstable product quality and too long production cycle.
[0003] In summary, due to the special materials and shapes used for the clamp parts of aircraft engine brackets and their excessive size, there is a problem of product interference when large U-shaped parts are bent during the processing using existing devices. Utility Model Content

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] The utility model provides a processing die for a bracket clamp, comprising an upper die and a lower die arranged below the upper die, wherein the upper die comprises an upper tool handle, a buffer spring and an upper tool head;
[0007] The buffer spring is arranged in a cavity opened inside the upper tool handle, the upper tool head is arranged below the buffer spring, the upper tool head is arranged to penetrate the upper tool handle horizontally, and a set safety distance is provided between the upper tool handle and the part to be bent;
[0008] The upper cutter head includes a mounting assembly and a cutter head processing assembly, and the cutter head processing assembly is arranged on the mounting assembly close to the lower die side;

A first gap is formed between the short side of the rectangular plate with missing corner and the mounting assembly, and a second gap is formed between the long side of the rectangular plate with missing corner and the processing component. The first gap and the second gap are used to prevent interference between the upper cutter head and the lower mold.
[0011] In a specific implementation process, a spring guard plate is also included, and the spring guard plate is arranged outside the buffer spring.
[0012] In a specific implementation process, the spring guard plate includes a first guard plate and a second guard plate, and the first guard plate and the second guard plate are respectively arranged on both sides of the upper handle.
[0013] In the specific implementation process, a groove is opened on the lower die, and the groove cooperates with the processing part of the upper cutter head to process the part to be bent.
[0014] In a specific implementation process, the length of the processing component is greater than the height of the groove, and the thickness of the processing component is less than the width of the groove.
[0015] In the specific implementation process, the set safety distance is 40 to 60 mm.
[0016] In a specific implementation process, the mounting assembly is a U-shaped assembly with an opening facing downward, and the mounting assembly penetrates through and is mounted on the upper handle.

[0019] Compared with the prior art, the utility model has the following beneficial effects:
[0020] The utility model provides a processing mold for a bracket clamp. The bracket clamp mold is divided into an upper and lower mold group. A bending machine is used to bend the bracket clamp U-shaped process, wherein the lower mold group is responsible for auxiliary bending, and the upper mold group is responsible for the fastening and active bending of the bracket clamp. Due to the protruding design of the upper cutter head, a set safety distance is set between the upper handle and the part to be bent, and a first gap is formed between the short side of the rectangular plate with a missing corner and the mounting assembly, and a second gap is formed between the long side of the rectangular plate with a missing corner and the processing part. The first gap and the second gap prevent the upper cutter head from interfering with the lower mold. The above processing mold can save the processing cost of bracket clamp parts, improve processing efficiency, and avoid the technical problem of product interference when bending large U-shaped parts caused by the bracket height being too high. The use of the processing mold provided by the utility model can increase the processing efficiency of the bracket clamp U-shaped process by 5 times and the quality pass rate by 3 times.
[0021] Furthermore, the upper cutter head in the upper die is pressed down, and the lower die and the upper cutter head cooperate to bend the parts. The upper cutter head and the parts to be bent are designed to have a safe distance to prevent the parts from turning up and hitting the equipment. Due to the thin thickness of the cutter head, the compression buffer spring plays a secondary buffering role on the upper cutter head to protect the cutter head. BRIEF DESCRIPTION OF THE DRAWINGS
