Abstract

The utility model discloses a die for USB terminals. The die comprises an upper die and a lower die corresponding to the upper die. A first work station, a second work station and a third work station are arranged between the upper die and the lower die sequentially. The first work station, the second work station and the third work station comprise two parallel upper punching protrusion blocks and two lower punching protrusion blocks corresponding to the upper punching protrusion blocks respectively. The die for USB terminals has the advantages that separated work stations are used, so that punching steps can distribute punching, middle portions, lower portions and tail portions of the terminals are punched according to the first work station, the second work station and the third work station successively, one-time punching is performed, the process is simple, and the tolerance is easy to control.

Description

A kind of USB terminal die

Technical field

The utility model relates to a kind of mould, relates in particular to a kind of USB terminal die.

Background technology

Technology of die manufacturing is the basis of modernized die ﹠ mold development, have moulding fast, can realize batch machining, machining accuracy is guaranteed, and wherein diel refers in Cold Press Working, metal or nonmetallic materials is processed into a kind of special process equipment of part.Punching press is at room temperature, utilizes the mould that is installed on the forcing press that material is exerted pressure, and makes it produce separation or plastic deformation, thereby obtains a kind of pressure processing method of required part.

The form of diel is a lot, generally divides by processing method mainly to comprise following several types:

Blanking die: the mould that makes the material production separation along the outline line that seals or open wide.Such as blanking die, perforating die, knife edge die, notch die, edger, parting die etc.

Bending die: make plate blank or other blanks produce flexural deformation along straight line (sweep), thereby obtain the mould of the workpiece of certain angle and shape.

Drawing Die: be that the plate blank is made the open hollow part, or make hollow object further change the mould of shape and size.

Finishing die: be that blank or semi-finished product workpiece are directly copied shaping by the shape of figure punch and matrix, and material itself only produces the mould of local plastic deformation.Such as bulging die, reducing die, flaring die, embossing die, flange die, sizing die etc.

Compression mould: be to utilize powerful pressure, make metal blank flow deformation, become required shape, its kind extrudes punch die, embossing punch die, impression punch die, side pressure punch die.

In die manufacture, it requires all relatively harsher to tolerance, material for the USB terminal, but this product is done by present most of producer, and tolerance all is difficult to control and puts in place.

The utility model content

Technical problem to be solved in the utility model provides that a kind of technique is simple, the USB Terminals Die of tolerance easy to control.

To achieve these goals, the utility model provides a kind of USB terminal die, comprise patrix and the counterdie corresponding with patrix, be provided with the first worker station, the second worker station and the 3rd worker station between described patrix and the counterdie, described the first worker station, the second worker station and the 3rd worker station are arranged in order, described the first worker station, the second worker station and the 3rd worker station include 2 upper punch belling pieces that are parallel to each other, and 2 the undershoot belling pieces corresponding with described upper punch belling piece.

Above-mentioned USB terminal die, preferred, described the first worker station comprises pressing block and 2 first time pressing blocks on 2 first, described each on first pressing block comprise the first groove, described each first time pressing block comprises first projection corresponding with the first groove.

Above-mentioned USB terminal die, preferred, described the second worker station comprises pressing block and 2 second time pressing blocks on 2 second, described each on second pressing block comprise the second groove, described each second time pressing block comprises second projection corresponding with the second groove.

Above-mentioned USB terminal die, preferably, described the 3rd worker station comprises pressing block and 2 the 3rd time pressing blocks on 2 the 3rd, described each on the 3rd pressing block comprise the 3rd projection, also be provided with the punching press base between described 2 the 3rd time pressing blocks, the height of described punching press base is less than described the 3rd time pressing block, and described the 3rd time pressing block and described punching press base form the 3rd groove, and described the 3rd groove is corresponding with the 3rd projection.

Technique effect of the present utility model is: owing to adopted the worker station of separating, the punching press so that punch steps can distribute, according to the first worker station, the second worker station and the 3rd worker station terminal middle part, bottom and afterbody are carried out punching press successively, then carry out a punching press, but technique is simple so that tolerance is more easy to control.

Fig. 3 is the schematic diagram at the 3rd worker of the present utility model station.

The specific embodiment

Below, by reference to the accompanying drawings the utility model is described further.

As shown in Figure 1, the utility model provides the utility model that a kind of USB terminal die is provided, comprise patrix and the counterdie corresponding with patrix, be provided with the first worker station, the second worker station and the 3rd worker station between described patrix and the counterdie, described the first worker station, the second worker station and the 3rd worker station are arranged in order, described the first worker station, the second worker station and the 3rd worker station include 2 upper punch belling pieces that are parallel to each other, and 2 the undershoot belling pieces corresponding with described upper punch belling piece.

Referring to shown in Figure 1, described the first worker station comprises pressing

block

1 and 2 first time pressing blocks 2 on 2 first, described each on first pressing block 1 comprise the first groove, described each first time pressing block comprises first projection corresponding with the first groove.

Referring to shown in Figure 2, described the second worker station comprises pressing

block

3 and 2 second time pressing blocks 4 on 2 second, described each on second pressing block 3 comprise the second groove, described each second time pressing block comprises second projection corresponding with the second groove.
