Abstract
The utility model discloses a roll for production of section copper strips. The roll comprises a flat roll body, wherein the middle of the flat roll body is provided with at least one groove for forming. The roll is characterized in that the connecting parts of the two sides of the groove and the flat roll body are respectively provided with a convex circular arc section, and the central angle of each circular arc section is controlled to 0-3 degrees. The roll for the production of the section copper strips has the advantage that the connecting parts of the two sides of the groove and the flat roll body are respectively provided with the corresponding convex circular arc section, and the tolerance of the thin edge of the processed section copper strip is controlled to be within 0.01mm by each circular arc section, so the processing precision is improved.
Description
Technical field
The utility model relates to a kind of roll, relates in particular to a kind of roll for the production of section copper strip.
Background technology
Special-shaped copper alloy band is conventionally by Cu-Fe-P alloy composition, the section of band is formed by thin, thick two kinds of specifications, thin material is lead-in wire, it is mainly used in power tube lead frame and LED lead frame and electronic connector in encapsulated semiconductor discrete device, and its product requires very high to outward appearance, material, dimensional accuracy, band template, surface roughness, residual stress and consistency of performance.
Roll is the vitals of producing section copper strip, the quality of its design directly determines the machining accuracy of section copper strip, traditional roll generally comprises plain-barreled roll body, on the centre position of described plain-barreled roll body, be provided with the groove for moulding, the roll of this kind of structure is flat roller structure being because of groove both sides, cause the section copper strip of production larger near the featheredge part tolerance of longitudinal boss, machining accuracy is low, is difficult to meet international standards.
Utility model content
The purpose of this utility model is to provide a kind of roll for the production of section copper strip, and it has the advantages that machining accuracy is high, to solve section copper strip in prior art, produces the problem existing with roll.
For reaching this object, the utility model by the following technical solutions:
For the production of a roll for section copper strip, it comprises plain-barreled roll body, offers at least one groove for moulding on the centre position of described plain-barreled roll body, and wherein, the position that the both sides of described groove and plain-barreled roll body join is provided with the arc section of a projection.
Especially, on the centre position of described plain-barreled roll body, offer two spaced apart grooves for moulding.
Especially, the central angle of described arc section is controlled between 0 °～3 °.
Especially, the groove depth of described groove is 0.6～1.4mm.
The beneficial effects of the utility model are, compared with prior art the both sides of the described knurling for the production of section copper strip and position that plain-barreled roll body joins all have additional the arc section of a projection, by this arc section, can make, in featheredge allowance control 0.01 ㎜ of section copper strip of processing, to have improved machining accuracy.
Accompanying drawing explanation
Fig. 1 is the structural representation of the roll for the production of section copper strip that provides of the utility model specific embodiment 1.
In figure:
1, plain-barreled roll body; 2, groove; 3, arc section.
The specific embodiment
Below in conjunction with accompanying drawing and by the specific embodiment, further illustrate the technical solution of the utility model.
Refer to shown in Fig. 1, Fig. 1 is the structural representation of the roll for the production of section copper strip that provides of the utility model specific embodiment 1.
In the present embodiment, a kind of roll for the production of section copper strip comprises plain-barreled roll body 1, on the centre position of described plain-barreled roll body 1, offer two spaced grooves 2 for moulding, the groove depth of described groove 2 is 0.6～1.4mm, the position that the outside of described two grooves 2 and plain-barreled roll body 1 join is provided with the arc section 3 of a projection, and the central angle of described arc section 3 is 2 °.By this arc section 3, can make, in featheredge allowance control 0.01 ㎜ of section copper strip of processing, to have improved machining accuracy.
Above embodiment has just set forth basic principle of the present utility model and characteristic; the utility model is not limited by above-mentioned example; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
