Description

Technical Field

[0001] The utility model relates to a quick removal process ear piece punching device, belonging to the field of sheet metal forming. Background Art

[0002] like Figure 1 As shown in the figure, a certain type of aircraft shearing angle piece part is used in batches of thousands of parts to strengthen the rigidity of the aircraft frame. The raw material of this part is a certain aviation aluminum material. Its notable appearance feature is that the web surface has a continuous irregular curved edge. During the research and trial production stage, this type of part is formed manually using a mold. However, after forming, the process ears on the part need to be trimmed off. In particular, when trimming the ears at the irregular curved edge, workers need to manually mark the edges first, such as Figure 2 As shown, the parts must be trimmed carefully and the trimmed parts must be polished and corrected, which is time-consuming and laborious and difficult to maintain the irregular curve shape of the parts. Utility Model Content

[0005] Preferably, pin holes are provided on the positioning card plate, the cover plate and the bottom plate, and the positions of the pin holes of the three correspond to each other.

[0006] Furthermore, it also includes a bow-shaped clamp for clamping the positioning clamp and parts between the cover plate and the base plate.

[0007] Preferably, the punch and the base plate are both made of steel.

[0008] Preferably, the positioning clamping plate is made of steel plate.

[0009] Preferably, the cover plate is made of aluminum ingot.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] 1. After adopting the blanking device, the part fully meets the design requirements, the workers save time and effort in operation, and the production efficiency is greatly improved;

[0022] The following is combined with Figure 3-6 The utility model is further described in detail: a device for quickly removing process ear pieces, the punching device includes a punch 6, a positioning card plate 2, a cover plate 3 and a bottom plate 4; wherein the punch 6 is made of steel material and has a curved groove, the groove is consistent with the trimming curve and edge curve of the process ear piece of the workpiece 1, such as Figure 4 As shown; the positioning card plate is made of steel plate, the wave shape matches the wave edge of the workpiece 1, and has a pin hole, as shown Figure 5 As shown; the cover plate 3 is made of aluminum ingot, with a wavy groove inside, the groove matches the wavy edge of the workpiece 1, and has a pin hole, the non-working edge is rounded, the bottom plate 4 has the same structure as the cover plate 3, and the bottom plate 4 is made of steel material, such as Figure 6 shown.

[0023] like Figure 3 As shown in the figure, the forming process of a certain type of aircraft shearing corner piece parts:

[0024] (1) Insert the pin 5 into the pin hole to flexibly connect the positioning card 2, cover plate 3 and base plate 4, leaving an appropriate gap between them;

[0025] (2) With the corrugated edge of the workpiece 1 facing the blanking device, the workpiece 1 is moved to the curved shape of the area without the ear piece and clamped into the positioning clamping plate 2, thereby determining the relative position relationship between the workpiece 1, the positioning clamping plate 2, the cover plate 3 and the bottom plate 4;

[0026] (3) Maintain the state of step (2) and further clamp and fix it with a bow clamp;

[0027] (4) Insert the punch 6 from the positioning groove in the cover plate 3 (already positioned) and position it with the wavy curved surface. Then apply an impact load to the punch 6 so that the ear can be quickly and accurately punched out.

[0028] As can be seen from the above, with this punching device, workers no longer need to mark and trim the lugs at the wavy contours or polish and correct the trimmed areas. This not only ensures the outer dimensions of the wavy edge of the workpiece 1, significantly improves production efficiency, and greatly reduces worker workload, successfully achieving the purpose of forming the workpiece 1. This also provides reference and inspiration for the forming of similar workpieces 1.
