Embodiment Construction

[0012] Such as figure 1 As shown, in this embodiment, a die for punching forgings includes a leaky plate 1 and a backing plate 2, a through hole 3 is opened in the middle of the leaky plate 1, and both sides of the through hole 3 at the lower end of the leaky plate 1 are welded With backing plate 2. The leakage disc 1 adopts 45 steel.

[0013] During production, the round blank 5 is placed on the drain plate 1, and the edges are aligned, and then aligned with the through hole 3 to start punching.

[0014] The punching die for the forging ensures the accuracy of punching, improves the quality, has good stability and high safety during punching.

Abstract

The invention discloses a mold for forge piece punching, which comprises a drain cap and a pad plate, wherein the middle of the drain cap is provided with a through hole, and the pad plate is welded at both sides of a through hole arranged at the lower end of the drain cap. The mold adopts the drain cap structure, the uniform stress during the punching is ensured, the through hole is formed in the middle of the drain cap, the punching accuracy is ensured, the eccentricity is avoided, the lower end of the drain cap is welded with the pad plate, and the damage to a work table during the punching is avoided.

Description

technical field [0001] The invention relates to a mold for production, in particular to a mold for punching forgings. Background technique [0002] At present, in the forging industry, when punching circular forgings, generally the finished round billet is placed flat on a parallel frame, and then punched. But when punching, due to the deviation of the position of the round billet, it is easy to cause eccentricity, and when placed on the parallel frame, due to the uneven force during punching, it is easy to cause the round billet to slip and cause danger. So a new type of die is needed for punching forgings. Contents of the invention [0003] The purpose of the present invention is to provide a die for punching forgings, which can ensure the accuracy of punching, improve the quality, and has good stability and high safety during punching. [0004] The purpose of the present invention is to realize through the following technical solutions: [0005] A mold for punching f...
