Stamping die with one-time forming with negative angle

Abstract

The invention discloses a stamping die capable of forming a folded negative angle once. The stamping die comprises an upper die and a lower die, wherein the upper die comprises an upper die base, an upper cushion plate and an upper die plate which are positioned from top to bottom; the lower die comprises a lower die base, a lower cushion plate and a lower stripper plate which are positioned from bottom to top; an elastic space is formed between the lower stripper plate and the lower cushion plate; a slide block is arranged on one side of the upper die plate; one side of the slide block is glidingly connected with that of the upper die plate; an elastic space is formed between the slide block and the upper cushion plate; the other side of the slide block is matched with the negative angle of a product needed to be subjected to negative angle folding in shape; an elastic mechanism is arranged on the lower cushion plate and positioned on one side of the lower stripper plate; one part of the product needed to be subjected to negative angle folding is arranged between the upper die plate and the lower stripper plate, and the other part of the product needed to be subjected to negative angle folding is arranged on the elastic mechanism; the elastic mechanism can be elastically against one side of the lower stripper plate. According to the stamping die, the folded negative angle can be formed once, so that the technological processes can be effectively reduced, the production efficiency can be improved, and the production cost of the product can be lowered.

Description

technical field [0001] The invention relates to a stamping die, in particular to a stamping die for one-time forming of a negative folding angle. Background technique [0002] Stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, called cold stamping die (commonly known as cold stamping die). Bending refers to the stamping process of bending the sheet into the required angle and shape along the bending line. At present, metal structural parts often need to be bent at a negative angle. When bending a product at a negative angle in the prior art, the product must first be bent to 90 degrees through a stamping die, and then bent to a required negative angle. The above-mentioned negative angle folding process is complex, and requires two sets of stamping dies, two operations to form, resulting in increased manufacturing costs and labor costs, low production and processing eff...
