Bending molding structure for stamping mould

Abstract

The invention relates to a bending molding structure for a stamping mould, which comprises an upper mould and a lower mould which is matched with the upper mould, wherein an oscillatory moveable insert is arranged on the lower mould; a bending stamping head which is matched with the oscillatory moveable insert is arranged on the upper mould; when the upper mould and the lower mould are closed, anangle bending slot which is used for realizing the bending of a product is formed between the bending stamping head and the oscillatory moveable insert; and an angle stamping piece which is used for controlling an oscillating angle of the oscillatory moveable insert is arranged on the upper mould. By adopting the bending molding structure provided by the invention, the negative angle bending molding of the product is realized, the purpose of once stamping negative angle bending molding of the product is realized and different demands on the machine-shaping with a bending angle are met. The bending molding structure has the advantages that the bending angle is conveniently adjusted, operation is simple, only once stamping is needed, tolerance caused by more than once stamping is avoided, processing precision of the product is promoted, quality of the product is ensured, operation is concise and simple, maintenance is conveniently realized, cost is low, time and labor are saved and processing efficiency is promoted.

Description

technical field [0001] The invention relates to a stamping die, in particular to a bending forming structure for the stamping die. Background technique [0002] The status of the mold industry in the national economy is rising day by day. Mold is the basic process equipment for industrial production. In products such as electronics, automobiles, motors, electrical appliances, instruments, home appliances and communications, 60% to 80% of the parts rely on molds. Forming, especially metal thin material bending processing products are widely used in IT communication electronics, electrical appliances and automobile manufacturing. Therefore, the quality of molds directly determines the quality of products. [0003] At present, in the stamping process, for the bending and forming of the product, especially the bending process that requires a negative angle, the existing stamping forming mold is generally completed in three stations: (1) First, the product is bent into a 45 degr...

Problems solved by technology

[0003] At present, in the stamping process, for the bending and forming of the product, especially the bending process that requires a negative angle, the existing stamping forming mold is generally completed in three stations: (1) First, the product is bent into a 45 degrees; (2), then continue to stamp the product folded into 45 degrees to 90 degrees, (3), and finally stamp the product into the required negative angle, that is, an angle greater than 90 degrees; this kind of bending stamping mold , not only expensive, but also complex operation, many processing procedures, time-consuming and labor-intensive, low processing efficiency, and it is difficult to change the size of the negative angle of stamping according to customer needs in the stamping process. The cost is high, and it is difficult to achieve the quality quality required by the product
