Description

Technical Field

[0001] This utility model relates to the field of removing excess material left during riveting and drilling processes inside aircraft cabins, specifically to a bending mold for clamp-type parts. Background Technology

[0002] Because aircraft hydraulic pumps generate pulsating flow outputs, the aircraft's hydraulic lines are subjected to pulsating fluid impacts. Excessive vibration and impact can cause the lines to rupture, leading to aircraft crashes. Therefore, pipe clamps are typically used to secure the hydraulic lines.

[0003] The production of pipe clamps requires bending dies, and clamp-type parts are generally bent by stamping sheet metal to obtain U-shaped clamp-type parts. However, existing bending dies can generally only bend one part at a time, resulting in low bending efficiency of clamp parts. Utility Model Content

[0004] To address the existing technical problems, this utility model provides a bending die for clamp-type parts, including a concave die and a convex die located above the concave die. The concave die includes a plurality of concave mold cavities and a concave mold base, and the plurality of concave mold cavities are all fixedly disposed on the concave mold base.

[0005] The punch includes several bending protrusions and a punch base, with the bending protrusions fixedly disposed on the punch base; each bending protrusion corresponds to one die cavity.

[0006] A further embodiment is that the vertical axis of the bent protrusion and the vertical axis of its corresponding concave mold cavity are on the same straight line.

[0007] A further embodiment is that the top of the punch holder is fixedly connected to the bottom of the punch fixing plate.

[0008] A further embodiment is that the top of the punch fixing plate is fixedly connected to the bottom of the die shank fixing plate, and a die shank is fixedly provided on the top of the die shank fixing plate.

[0009] A further embodiment is that the bottom of the die holder is fixedly connected to the top of the die fixing plate.

[0010] A further option is to fix the bottom of the concave mold fixing plate to the top of the lower mold plate.

[0011] The beneficial effects of this utility model are:

[0012] This invention provides a bending die that can simultaneously bend and form several U-shaped clamp-like parts by setting several concave mold cavities on the concave mold and several bending protrusions on the convex mold, with the concave mold cavities and bending protrusions corresponding one-to-one. This improves the bending efficiency and accuracy. Attached Figure Description

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] like Figure 1-2 As shown, one embodiment of this utility model discloses a bending die for clamp-type parts, including a concave die 1 and a convex die 2 located above the concave die 1. The concave die 1 includes two concave mold cavities 10 and a concave mold base 11, and the two concave mold cavities 10 are fixedly arranged on the concave mold base 11.

[0018] The punch 2 includes two bending protrusions 20 and a punch base 21. Both bending protrusions 20 are fixedly mounted on the punch base 21; each bending protrusion 20 corresponds to a cavity 10.

[0019] In this embodiment, the top of the punch fixing plate 3 is fixedly connected to the bottom of the die shank fixing plate 4, and a die shank 40 is fixedly provided on the top of the die shank fixing plate 4. This achieves the fixed installation of the punch fixing plate onto the die shank fixing plate.

[0020] It should be noted that the die shank in this embodiment is detachably and fixedly connected to the stamping mechanism of an existing punch press, thereby driving the die shank fixing plate to move in the vertical direction.

[0021] This embodiment, through the above-described configuration, enables the bending die to be assembled while simultaneously allowing the stamping mechanism of the die holder press to be detachably and fixedly connected. Then, the blank material of the clamp-like part to be bent is placed on the cavity of the die. The press is started, causing the punch to move downwards vertically. When the punch contacts the blank material, it bends along the cavity. After bending, the press drives the punch upwards vertically, returning it to its initial position. Bending is then complete, and the bent part can be removed from the die. This embodiment's bending die can simultaneously bend two U-shaped clamp-like parts, improving bending efficiency and accuracy.

[0022] In this embodiment, the vertical axis of the bent protrusion 20 and the vertical axis of its corresponding concave mold cavity 10 are on the same straight line.

[0023] This embodiment enables precise positioning and bending of clamp-type parts through the above settings.

[0024] In this embodiment, the top of the punch base 21 is fixedly connected to the bottom of the punch fixing plate 3.

[0025] This embodiment achieves the fixed installation of the punch onto the punch fixing plate through the above settings.

[0026] In this embodiment, the top of the punch fixing plate 3 is fixedly connected to the bottom of the die shank fixing plate 4, and the top of the die shank fixing plate 4 is fixedly provided with a die shank 40.

[0027] This embodiment achieves the fixed installation of the punch fixing plate onto the die shank fixing plate through the above settings.

[0028] In this embodiment, the bottom of the die holder 11 is fixedly connected to the top of the die fixing plate 5.

[0029] This embodiment achieves the fixed installation of the die onto the die fixing plate through the above settings.

[0030] In this embodiment, the bottom of the concave mold fixing plate 5 is fixedly connected to the top of the lower template 6.

[0031] This embodiment achieves the fixed installation of the concave mold fixing plate onto the lower template through the above settings.

[0032] Finally, it should be noted that the above description only details specific embodiments of this utility model. However, this utility model is not limited to the specific embodiments described above. Equivalent modifications and substitutions made to this utility model by those skilled in the art are also within the scope of this utility model.
