Abstract
Description
Technical Field
[0001] This utility model belongs to the field of edge cutting technology for clamp-type parts, and specifically relates to an edge cutting mold for clamp-type parts. Background Technology
[0002] Aircraft clamps are plate-bending parts used to connect pipes. Due to the numerous and varied pipe diameters in aircraft, a large quantity of aircraft clamps are required, and they come in various models. U-shaped clamps, as common aircraft fixing parts, also have correspondingly high precision requirements. They are generally machined directly using stamping dies to ensure machining accuracy. Clamp forming typically requires three sets of molds: two sets for machining the shape of the clamp, and one set for edge stamping at the hole-forming station to place the other end while cutting the edge at one end. Three sets of molds can produce one U-shaped clamp in one process cycle. However, the U-shaped clamp is difficult to position, leading to a decrease in machining accuracy, resulting in low clamp machining precision and low efficiency. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a clamp-type part cutting mold with a simple structure and convenient and practical design. The clamp part is positioned by positioning groove, which improves the positioning accuracy of the clamp part and can process two U-shaped clamps at one time, thereby ensuring the cutting accuracy of the clamp part while improving the processing efficiency.
[0004] A clamp-type part trimming mold includes a concave mold, an ejector plate, a convex plate, a clamp part, a fixing plate, a lower template, and an upper template. The concave mold is connected to the upper template, and the convex plate and the fixing plate are connected to the lower template. One end of the convex plate passes through the fixing plate, the ejector plate, and the concave mold. The ejector plate is slidably connected to the convex plate, and the clamp part is disposed on the ejector plate.
[0005] Preferably, it includes a guide post and a flat-head pin. One end of the guide post is connected to the lower template and the other end passes through the fixing plate and the top plate. One end of the flat-head pin is connected to the fixing plate and the other end passes through the top plate. A return spring is sleeved on the guide post and the return spring is disposed between the fixing plate and the top plate.
[0006] Preferably, the top plate has two symmetrical positioning grooves. Beneficial effects
[0007] (1) The present invention provides a clamp-type part cutting mold, which has a simple structure and is convenient and practical. The clamp part is positioned by positioning groove, which improves the positioning accuracy of the clamp part and processes two U-shaped clamps at one time, thereby ensuring the cutting accuracy of the clamp part while improving the processing efficiency.

[0011] The embodiments of this utility model are further described below with reference to the accompanying drawings. Example
[0012] like Figures 1 to 2 As shown; a clamp-type part trimming mold includes a concave mold 1, an ejector plate 2, a protruding plate 3, a clamp part 4, a fixing plate 5, a lower template 6, and an upper template. The concave mold 1 is connected to the upper template, and the protruding plate 3 and the fixing plate 5 are connected to the lower template 6. One end of the protruding plate 3 passes through the fixing plate 5, the ejector plate 2, and the concave mold 1. The ejector plate 2 is slidably connected to the protruding plate 3. The clamp part 4 is disposed on the ejector plate 2. It includes a guide post and a flat-head pin. One end of the guide post is connected to the lower template 6, and the other end passes through the fixing plate 5 and the ejector plate 2. One end of the flat-head pin is connected to the fixing plate 5, and the other end passes through the ejector plate 2. A return spring is sleeved on the guide post, and the return spring is disposed between the fixing plate 5 and the ejector plate 2. Two positioning grooves 7 are symmetrically opened on the ejector plate 2.
[0013] The lower template 6 and the upper template are respectively installed on the die head and base platform of the stamping machine. Then, the clamp part 4 is placed on the top plate 2. The two U-shaped clamps of the clamp part 4 are respectively locked in the corresponding positioning grooves 7. The positioning grooves 7 are used to position the two ends of the clamp part 4. The clamp part 4 is composed of two U-shaped clamps. The die head of the stamping machine drives the die 1 to move down, so that the top plate 2 and the die 1 close together and press the clamp part 4 between them. Then the die 1 continues to move down and drives the top plate 2 to move down. At the same time, the die 1 and the punch 3 cooperate to cut the edge of the clamp part 4, so that the clamp part 4 is cut into two U-shaped clamps. After the processing is completed, the die head drives the die 1 to rise. This cycle continues. When the top plate 2 moves down, the spring is compressed. When the top plate 2 rises, the spring will drive the top plate 2 to rise and reset, and the height of the rise is limited by the flat pin.

For those skilled in the art, any equivalent modifications and substitutions to this utility model are also within the scope of this utility model. Therefore, all equivalent changes and modifications made without departing from the spirit and scope of this utility model are covered within the scope of this utility model.
