Abstract

The invention discloses a chamfering die and relates to a cold stamping die. The chamfering die is designed for solving the problems the step-by-step thinning stamping is mostly adopted for generating chamfer angels against the current various terminal products during the production process, the manual operation is time-consuming and a chamfering machine can easily produce phenomena of scratches and burrs on the surfaces of the products. The chamfering die comprises a male die and a female die which are matched, and the male die and the female die have a chamfering upper die and a chamfering lower die which correspond to the shape of chamfer angle parts of the products. The chamfering die is particularly suitable for die-pressing production of metal parts with chamfer angles at the end parts.

Description

A kind of chamfer mould

Technical field

The present invention relates to a kind of cold punching die, relate in particular to a kind of chamfer mould.

Background technology

Many fingers of binding post line terminal, kind has single hole, diplopore, socket, and hooks etc. have copper silver-plated from materials classification, and copper is zinc-plated, copper, aluminium, iron etc.For example, LCD (LCD) terminal is the vitals that connects LCD, is connected the transmission that realizes the signal of telecommunication with display screen through it.Similarly, the battery terminal in the notebook also has the effect of electrical connection.Mostly above-mentioned various terminals are that end face has the metallic stamping pieces of chamfering.

Present most of enterprise is in the process of producing products such as battery terminal; The mode of utilizing beveler to thin stamping parts end right-angle side step by step produces chamfering more; Manually-operated is not only consuming time, and beveler is prone to make product surface to occur scratching and burr phenomena, has a strong impact on product quality.

Summary of the invention

To existing various terminal products in process of production, the substeps that adopt thin stamping parts producing chamfering more, and the not only consuming time and beveler of manually-operated is prone to make product surface to occur scratching and the deficiency of burr phenomena.The chamfer mould that the purpose of this invention is to provide a kind of disposable generation chamfering.

The technical solution adopted for the present invention to solve the technical problems is: it comprises punch and the die that matches, and said punch and said die have and corresponding chamfering patrix of product chamfered section shape and chamfering counterdie.

Further, the longitudinal section of said chamfering patrix and chamfering counterdie is straight chamfering or rounded corner.

The beneficial effect of this patent is: the present invention adopts up and down corresponding chamfer mould punching press to produce the chamfered section of terminal product, and disposable drawing, and dimensioned is accurate; No burr; Need not secondary operations, guaranteed product quality, and improved production efficiency.

The specific embodiment

In conjunction with Fig. 1 to Fig. 6 a kind of chamfer mould of the present invention is described, it comprises punch and the die that matches, and punch and die have and corresponding chamfering patrix 1 of product chamfered section shape and chamfering counterdie 2.The longitudinal section of chamfering patrix 1 and chamfering counterdie 2 is straight chamfering or rounded corner.Wherein, punch from top to bottom is fixedly connected sequentially by upper bolster, upper padding plate and chamfering patrix 1.Die from top to bottom is fixedly connected sequentially by chamfering counterdie 2, lower bolster, die shoe and mould pin.Chamfering patrix 1 is corresponding with the chamfered section shape of terminal 3 with chamfering counterdie 2, and punch and die are installed on the punch press.

Blank to be processed between the punch and die of chamfer mould, stroke of punch on punch press action, chamfering patrix 1 is formed with corresponding chamfering with chamfering counterdie 2 at the end face of blank to be processed; And adopt high-accuracy, minute surface edm; Dimensioned is accurate, and no burr need not secondary operations; Guarantee product quality, and improved production efficiency.

Those skilled in the art will recognize that; The above-mentioned specific embodiment is exemplary; Be in order to make those skilled in the art can better understand this patent content; Should not be construed as is the restriction to this patent protection domain, changes or modifies so long as disclose spiritual any being equal to of being done according to this patent, all falls into this patent protection domain.

Claims (2)

1. a chamfer mould comprises the punch and the die that match, it is characterized in that: said punch and said die have and corresponding chamfering patrix of product chamfered section shape and chamfering counterdie.

2. chamfer mould according to claim 1 is characterized in that: the longitudinal section of said chamfering patrix and chamfering counterdie is straight chamfering or rounded corner.
