Example Embodiment

[0018] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] see image 3 , The punching die suitable for the arc hole of the present invention includes: an upper die set and a lower die set. Wherein, the upper module includes: upper die base 1, upper backing plate 2, punching needle fixing plate 3, which are arranged in order from top to bottom, and the lower module comprises: lower die holder 4, lower backing plate 5, concave die 6, punching The needle fixing plate 3 is integrally formed with a dummy punch 7 corresponding to the punching position of the product to be punched, and the die 6 is formed with a blanking hole 61 corresponding to the punching position of the product to be punched.

[0020] The so-called "copy punching needle 7" means that the shape of the punching needle imitates the shape setting of the punching hole, see figure 1 and figure 2 , Because the punching density is hig...

Abstract

The invention discloses a punching die suitable for cambered holes. The punching die comprises an upper die set and a lower die set, wherein the upper die set comprises an upper die holder, an upper base plate and a punching needle fixing plate which are sequentially arranged from the upper part to the lower part, the lower die set comprises a lower die holder, a lower base plate and a female die, a copying punching needle corresponding to the punching position of a product to be punched is integrally molded on the punching needle fixing plate, and a blanking hole corresponding to the punching position of the product to be punched is formed in the female die. The punching die has the effects that the punching die is suitable for stamping the cambered holes and is particularly suitable for stamping the cambered holes with high density and length larger than the hole diameter, the punching quality is ensured through the adoption of a multi-stage progressive punching mode, and meanwhile, the service life of the copying punching needle is also prolonged; punching waste materials do not need to be manually cleared; the waste materials can be knocked out by an knock-out plate provided with a lug and then can be cleared through the assist of blow sweeping equipment in blow sweeping, so that the clearing of the waste materials is safe and efficient.

Description

technical field [0001] The invention relates to a punching die, in particular to a punching die suitable for punching holes on the arc surface of products such as notebook casings, TV casings, display casings and the like. Background technique [0002] Such as figure 1 In the notebook case shown, in order to ensure the heat dissipation performance, there are a large number of heat dissipation holes with a small diameter (1.0-1.5mm) at A and B shown in the figure. More importantly, these heat dissipation holes It is located on the arc surface, and the length is much larger than the hole diameter, so it is difficult to punch holes. The traditional punching dies cannot meet the punching quality and precision, and the strength of the dies cannot meet the requirements for use. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the purpose of the present invention is to provide a punching die, which is suitable for punching holes on the arc ...
