Abstract

The utility model discloses a stamping die for producing a socket iron case of an SD (secure digital) storage card, and relates to a cold stamping die, which aims to solve the problems that products are easy to deform during demoulding, labor is consumed and cost rises as a right angle is formed by a slider during production of an existing SD storage card socket metal shell. The stamping die comprises a male die, a female die and a portal intermediate die, wherein the male die and the female die are matched with each other, and the portal intermediate die is used for forming a right-angle bent portion of a T-shaped end of the socket iron case. The portal intermediate die comprises an upper die and a lower die which are columnar, the cross section of the upper die is U-shaped, and the end face of the lower die for forming is matched with a groove of the upper die. The stamping die is particularly applicable to producing the socket iron case of the SD storage card.

Description

A kind of diel of producing SD memory card socket iron-clad

Technical field

The utility model relates to a kind of cold punching die, relates in particular to a kind of diel of the SD of production memory card socket iron-clad.

Background technology

SD (Secure Digital Card, i.e. safe digital card) storage card is a kind of brand-new storage card product, is used for MP3, DV, digital camera, e-book, AV equipment or the like more, especially is widely used on the ultra-thin digital camera.The SD storage card is 9 pins, and purpose is parallel through being become transmission means by serial, and to improve transmission speed, simultaneously, security is also higher.

SD storage card private jack has and prevents the locked configuration that storage card is arbitrarily extracted and prevent the anticreep design that storage card comes off.Therefore, the metal shell of socket structure is complicated (referring to Fig. 2) comparatively, and there are 90 degree dogleg section of symmetry on its metal shell both sides, and the right angle bending part can not have distortion, and in addition, this product has the barb position, has strengthened the difficulty of processing.At present, a lot of manufacturing enterprises are when this series products of processing, and the mode of utilizing slide block to be shaped is processed the right angle bending part more, but slide block is when the demoulding, are prone to product is pullled and caused distortion, cause frequently to repair a die, and consume a large amount of manpowers, and product cost rises.

Summary of the invention

In existing SD memory card socket metal shell production process, utilize slide block shaping right angle portion, be prone to cause the product distortion during demoulding, consume the deficiency that manpower and cost rise.The purpose of the utility model provides a kind of diel of the SD of production memory card socket iron-clad.

The utility model solves the technical scheme that its technical problem adopted: comprise the punch and the die that match, it also comprises the door shape gap bridge mould of the right angle dogleg section of the T shape end that is used to form said socket iron-clad.

Further, said door shape gap bridge mould comprises the upper die and lower die of column, and said patrix cross section takes the shape of the letter U, and the end face that is used to be shaped on the said counterdie matches with the groove of said patrix.

Further, said counterdie is made up of the J-shaped member that symmetrically arranged two cross sections are J-shaped.

Further, the edge at the position of said J-shaped member and said upper mould contact is provided with the boss that adapts with the right angle dogleg section of said T shape end.

Further, the width D 1 of said boss is less than the width of the right angle dogleg section of said T shape end, the height D2 of said boss greater than on the said T shape end near the length of the straight flange of said boss side surfaces.

The beneficial effect of this patent is: the door shape gap bridge mould that utilizes the utility model; The right angle bending part of storage card T shape end is shaped does not accurately have distortion; Product after the bending is fastened on the counterdie of shape gap bridge mould; Socket iron-clad after the shaping is in the walking of the counterdie of door shape gap bridge mould, until being ejected counterdie, and the distortion of having avoided housing to cause when pullling the demoulding.The door shape gap bridge mode structure of the utility model is simple, is easy to safeguard that product stripping is convenient, and breaks away from naturally not have and pull distortion, has guaranteed the quality that metal shell is processed.

The specific embodiment

The diel of a kind of SD of production memory card socket iron-clad of the utility model is described in conjunction with Fig. 1 to Fig. 4; Diel is made up of punch that matches and die; Punch is by upper bolster, the upper padding plate of pad punching pin, and punch fixing plate and the punching pin that is used for punching press from top to bottom are fixedly connected sequentially.Die from top to bottom is fixedly connected sequentially by lower bolster, die shoe and mould pin, each the die parts that matches with punching pin on the punch according to the Sheet Metal Forming Technology fixed order on the corresponding position of lower bolster.Punch and die are installed on the punch press.

Diel also comprises the door shape gap bridge mould of the T shape end 6 that is used to form rectangular bending on the socket iron-clad, and door shape gap bridge mould comprises the patrix 1 and counterdie 2 of column, and the cross section of patrix 1 takes the shape of the letter U, and the end face that is used to be shaped of counterdie 2 matches with the groove of patrix 1.Counterdie 2 is made up of the J-shaped member 3 that symmetrically arranged two cross sections are J-shaped.Contact with patrix 1 edge at position of J-shaped member 3 is provided with a boss 4, and the width D 1 of boss 4 is less than the width of the right angle dogleg section 6 of T shape end 5.The height D2 of boss 4 greater than on the T shape end 5 near the length of the straight flange of boss 4 sides.

The preprocessing metallic plate is between the punch and die of diel; Stroke of punch action on the punch press; The move forward distance of a station of the preprocessing metallic plate level on the strip of being positioned at; The punch of punch press moves next stroke, so back and forth, on the preprocessing metallic plate, accomplishes actions such as punching press bullport, blanking, bending 45 degree and bending 90 degree.After T shape end 5 punching presses of socket iron-clad both sides symmetry are accomplished, get into next station, to T shape end 5 bendings 45 degree; Subsequently, access door shape gap bridge die worker position, stroke of punch action; The patrix 1 of door shape gap bridge mould is accomplished T shape end 5 bendings 90 degree with counterdie 2, and the straight flange of two T shape ends 5 is fastened on the boss 4 of two J-shaped members 3 punching press of a socket iron-clad of completion; The preprocessing metallic plate continues feeding, and the socket iron-clad continues walking forward along the counterdie of door shape gap bridge mould, so back and forth; A plurality of socket iron-clads of completion punching press are arranged on the counterdie and move ahead; Until being ejected counterdie one by one, the distortion of having avoided socket iron-clad housing to cause when pullling the demoulding has guaranteed the quality of product.

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.
