Embodiment Construction

[0017] The present invention will be described in detail below with reference to the accompanying drawings.

[0018] See figure 1 A small hole anti-skip device of this embodiment includes a lower template 1, a lower backing plate 2 is provided under the lower template 1, and the lower template 1 is provided with a first through hole for punching small holes, and the lower backing plate 2 A second through hole is provided below the first through hole. The lower backing plate 2 is provided with a first groove 21. The first groove 21 is provided with a flexible air pipe 3 and a fixing device for fixing the flexible air pipe 3, the flexible air pipe 3 The outlet end of the valve is bent downward and communicates with the second through hole.

[0019] In the prior art, the lower template 1 and the lower backing plate 2 are provided with air inlets. Due to the extremely irregular shape and direction of the air inlets, it is difficult to process and cannot be used flexibly. The lower bac...

Abstract

The invention discloses a material-jump-preventing device for small holes. The device comprises a lower die plate, wherein a lower base plate is arranged below the lower die plate, a first through hole used for punching small holes is formed in the lower die plate, a second through hole is formed in the position, below the first through hole, of the lower base plate, a first groove is formed in the lower base plate, a flexible gas tube and a fixing device for fixing the flexible gas tube are arranged in the first groove, and the gas outlet end of the flexible gas tube is bent downwards and communicated with the second through hole. According to the material-jump-preventing device for small holes, the groove is formed in the lower base plate and easy to machine, the flexible gas tube with the gas outlet end bent downwards is arranged in the groove, and therefore gas flow can flow downwards, negative pressure is generated above the gas outlet end of the flexible gas tube, adsorption force for punching waste and dust is generated, the waste and the dust are made to fall off, and the problems that the waste jumps and the small holes are blocked are effectively solved.

Description

Technical field [0001] The invention relates to a mold, in particular to a small hole anti-jumping device. 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. Stamping die is an indispensable process equipment for stamping production and is a technology-intensive product. The quality, production efficiency and production cost of stamping parts are directly related to mold design and manufacturing. The level of mold design and manufacturing technology is one of the important indicators to measure the level of product manufacturing in a country, and to a large extent determines the product quality, efficiency and new product development capabilities. [0003] Existing stamping dies mainly include punches and dies. For punching dies for punching small holes, the punch of the punch is elongated, and the punch is provided with through holes correspond...
