Abstract

The invention discloses a fixed supporting type negative angle forming die of plates. The fixed supporting type negative angle forming die is used in stamping and is composed of sliding blocks, a base plate, a die holder, an upper die pressing block, a lower die pressing block, nitrogen springs and an ejection block, wherein the ejection block is fixed to the die holder, the base plate and the ejection block are relatively fixed to the die holder, the nitrogen springs are vertically arranged between the base plate and the ejection block, the horizontal sliding block is arranged on the base plate in a stacked mode, the lower die pressing block is arranged on the ejection block, and the upper die pressing block is arranged on the lower die pressing block and is fixed to a stripper plate. According to the die, because a fixed supporting structure is arranged and the resetting function of the nitrogen springs is realized, stripping is smooth in the forming process, product appearances are protected against friction damage, and the comprehensive indicator requirements for high efficiency, high quality, safety and economization of negative angle forming and stamping of the plates can be met.

Description

technical field [0001] The utility model relates to a negative-angle forming die of a fixed support type sheet material used in stamping processing. Background technique [0002] Stamping processing is one of the various types of mechanical processing. It is used to meet the needs of various stamping processing. It has the characteristics of high efficiency, high quality, simplicity, and low carbon. It is widely used in the field of production and processing. [0003] There are processing requirements for negative angle forming of sheet metal in stamping processing. [0004] In the previous forming method of negative angle forming mold for sheet metal, considering the problems of material stripping and pressing, the pressing block of the upper die and the pressing block of the lower die press the sheet, set them horizontally on the slider, and pass the punch down, the punch The horizontal thrust generated after the inclined surface contacts the inclined surface of the slide...
