Embodiment Construction

[0015] Such as image 3 A specific embodiment is shown, which includes a die and a punch 3, the die is provided with a cavity, the punch includes a punch body 3-2, and one side of the punch body 3-2 is provided with a boss 3 -3, the included angles between the two sides of the boss 3-3 and the plane on the punch body 3-2 where the boss 3-3 is located are all acute angles, so that the boss 3-3 is dovetail-shaped. The mold cavity of the die is corresponding to the shape of the punch main body 3-2, that is, the die has a dovetail-shaped groove.

[0016] The angle between the two sides of the boss 3-3 is preferably 30 degrees, so that the punched waste can form two sharp corners, and the two sharp corners are stuck in the mold cavity, and the waste is not easy to jump out.

[0017] The top surface of the boss 3-3 is preferably a plane, which is convenient for processing the punch 3.

[0018] On punch 3, preferably also adopt following structure: between the side surface and top ...

Abstract

The invention discloses a special-shaped punch type waste material jumping prevention mold, which comprises a female mold and a punch, wherein a die cavity is arranged in the female mold, the punch comprises a punch main body, at least one side of the punch main body is provided with a lug boss, included angles between two side surfaces of the lug boss and the plane of the punch main body, on which the lug boss is arranged, are respectively acute angles, and the shape of the mold cavity of the female mold is matched with the shape of the punch main body. One lug boss is arranged on waste materials punched by the mold, the lug boss of the waste materials is buckled with a corresponding groove in the mold cavity, the friction force is greater, and the waste materials cannot be taken out by the punch. The special-shaped punch type waste material jumping prevention mold is particularly suitable for punching and shearing samples with a special-shaped region to be punched and shorn and lower precision requirements on the product size.

Description

technical field [0001] The invention relates to a mold, in particular to a punching and shearing mold. Background technique [0002] In general stamping dies, when the shape is cut, only one side is cut. Due to the high-speed operation of the punching machine, the waste is often brought up, or there is oil on the waste, which sticks to the punch and brings out the knife edge to press the product. Injury, severe cases will break the mold. [0003] Especially in punching and shearing such as figure 1 When the shown area 2 to be punched and sheared is a special-shaped sample 1 to be punched and sheared, it is difficult to process a special-shaped structure corresponding to the area 2 to be punched and sheared because the punch and the die are difficult to process, so the prior art designs the punch The cross-section of the main body is designed to cover the cuboid of the area to be punched and sheared 2, which will inevitably lead to non-contact between the punched waste and ...
