Problems solved by technology

[0004] Although the above-mentioned bending die can reduce the indentation on the surface of the sheet metal workpiece, since there is no device on the lower mold base 1 to automatically eject the bent sheet metal workpiece, it needs to be manually removed from the V-shaped groove 2. Taking out the sheet metal workpiece is time-consuming and laborious

Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0014] see figure 2 , is a bending die 100 provided by the present invention, which is used for bending a workpiece 200 . The bending die 100 includes an upper die 10, a lower die 20 and a fixed base 30, the upper die 10 has a punch 11, the lower die 20 is fixed on the fixed base 30, and the workpiece 200 placed between the punch 11 and the lower die 20 . A pair of turning components 40 are accommodated on the lower die 20 and opposite to the punch 11 of the upper die 10 , and the turning components 40 can form a bending angle of the workpiece 200 . An elastic component 50 is accommodated in the lower die 20 , and the elastic component 50 can automatically eject the workpiece 200 after the workpiece 200 is bent.

[0015] In this embodiment, the shape of the end face of the punch 11 of the upper die 10 is V-shaped.

[0016] Please also refer to Figure 3...

Abstract

The invention provides a bending die for bending a workpiece. The bending die comprises an upper die, a lower die and a fixed pedestal, wherein the upper die is provided with a punching head; the lower die is fixed on the fixed pedestal; the workpiece is arranged between the punching head and the lower die; the lower die is provided with a body; the surface of the body facing to the upper die is provided with a first groove; a pair of overturning components are accommodated in the first groove; a clearance is formed between the pair of the overturning components, and is opposite to the punching head. When the punching head presses downwards, the overturning components rotate and form a second groove; at least one through hole which passes through the first groove and the bottom of the body is arranged in the body; a pair of elastic components are accommodated in the through hole and are supported against two sides of the clearance to ensure that the workpiece can be ejected out of a second groove in a process of elastic recovery of the elastic components.

Description

technical field [0001] The invention relates to a mechanical mold, in particular to a bending mold. Background technique [0002] The existing sheet metal non-marking bending die usually includes an upper die and a lower die, the upper die includes a punch, and the lower die is provided with a first groove for forming, and the sheet metal workpiece is pressed by the punch. into the first forming groove, the sheet metal workpiece can be bent according to the angle of the forming first groove. [0003] Such as figure 1 Shown is a schematic diagram of the lower mold base 1 of the existing bending mold. A V-shaped groove 2 is opened on the lower mold base 1, and an O-shaped storage groove 3 is opened on both sides of the opening of the V-shaped groove 2 and an arc R is formed. A cylinder is installed in the O-shaped storage groove 3. Body 4. The inner diameter of the O-shaped housing groove 3 matches the section radius of the cylinder 4, and the former is slightly larger tha...
