Embodiment 1

[0020] Example 1, such as image 3 As shown, this embodiment is a complete figure 1 , figure 2 The progressive die of the bracket shown is a type of progressive die for side hole forming and deep drawing. The whole progressive die includes a deep drawing device set in the drawing station to draw the material strip and the upper side hole on the side wall In the side hole forming device for forming, there is an empty station spaced between the drawing and punching and the punching and drawing. The punching guide hole and the process notch device are set on the station before the drawing device, The punching process notch device is provided at the station between the punching guide hole and the drawing device, and the shaping device is provided at the station between the second drawing device and the side punching device, The bottom surface pressing device set at the station of the side punching device is set, and the station after the bottom pressing device further includes an e...

Abstract

The invention discloses a side hole forming and deep drawing type progressive die which comprises a deep drawing device and a side hole forming device, wherein the deep drawing device is arranged in a deep drawing station and is used for deep drawing a material tape; the side hole forming device is used for side hole forming on material tape drawing and a side wall, and the side hole forming device is arranged on a station in the deep drawing device and comprises a station arrangement structure, an elastic structure, an upper die, an lower die, an unloading structure and a punching structure for punching side holes. Because a deep drawing die and a punching die are assembled to form the progressive die of the invention, the invention has greatly improved machining efficiency and can realizes fast and large-scale production and timely product supply compared with the traditional multiple-die single-procedure machining mode; meanwhile, labor cost is greatly reduced, and an operator can be more relaxed. In addition, an accuracy error caused by moving a workpiece blank among different stations is also avoided so that machining accuracy is higher and quality stability is better.

Description

Technical field [0001] The invention relates to the technical field of mold design, in particular to a progressive die for side hole forming and deep drawing. Background technique [0002] Progressive die, also called continuous die, is composed of multiple stations, each station is connected in sequence to complete different processing, and a series of different stamping processing is completed in one stroke of the punching machine. After one stroke is completed, the punch feeder moves the material forward in a fixed step, so that multiple processes can be completed on a pair of molds, generally including punching, blanking, bending, trimming, and stretching and many more. [0003] The progressive die is a relatively advanced die at this stage. Its most fundamental principle is to combine the original multiple stamping and forming dies to achieve multi-process automation. It has the advantages of high efficiency and better processing quality. A major development direction of sta...
