Abstract

The invention discloses a reflecting sheet serrated knife which is formed by a group of serrated knife units which are continuously arranged at intervals, wherein each serrated knife unit consists of a main serrated knife and two stop knives which are respectively and vertically arranged at the left side and the right side of the main serrated knife. The tooth width of the stop knife is 0.5MM, the distance between the stop knife and the main tooth knife which are respectively arranged at the two sides of the main tooth knife at intervals is 0.5MM, the distance between the stop knife between two adjacent units is 4MM, and the distance between two stop knives in the same unit is 5 MM. Compared with the prior art that the reflecting sheet serrated knife is formed by the single main serrated knife at intervals, the stopping knives are additionally arranged on the two sides of the main serrated knife, and the punched serrated knife line can be prevented from extending and breaking to the position of the stopping line at most due to the existence of the stopping line, so that the serrated knife line cannot be further extended and broken. The punched serrated knife line is folded in half by 180 degrees, and as can be seen from fig. 6, the finished product quality of the reflector plate is greatly improved.

Description

A kind of reflector plate serrated knife

Technical field

The present invention relates to a kind of cutter, refer to that especially a kind of etching mould that is used for the punching out reflector plate uses cutter.

Background technology

By the reflector plate serrated knife line that etching stamping system forms, because the material otherness of reflector plate is big, meet the high reflector plate of former material material fragility especially, because the high fragility of reflector plate, the serrated knife line after the punching out very easily produces and breaks when carrying out the doubling action.Like Fig. 1, shown in 2, existing reflector plate serrated knife is consecutively arranged to form by one group of master's serrated knife 1 at interval.Fig. 3 has provided and has used this existing serrated knife punching out to be prone to the crisp reflector plate that is prone to break, the experimental data that serrated knife line 11 parts of accomplishing with 180 ° amplitude doubling punching out are drawn.Adopting the main serrated knife 1 (" size interval " among the figure is meant the operator facewidth-operator space width, and unit is MM) of different size, from table, can find out, according with process requirements be merely the serrated knife that the size of space is " 3-5 ", " 4-5 ", product percent of pass is extremely low.

Summary of the invention

To the weak point that exists in the prior art, the present invention provides a kind of reflector plate serrated knife simple in structure, and it has obviously improved the serrated knife line and has extended the phenomenon of breaking, and the reflector plate after doubling repeatedly is still neat on the whole attractive in appearance.

For realizing above-mentioned purpose, technical scheme of the present invention is:

A kind of reflector plate serrated knife, it is consecutively arranged to form by one group of serrated knife unit interval, and described serrated knife unit is made up of a main serrated knife and two block cuttves, and two block cuttves are vertically installed in the main serrated knife left and right sides respectively.

Described block cutter tooth is wide to be 0.5MM.

Being arranged at intervals at the block cutter of main serrated knife both sides and the spacing of main serrated knife respectively is 0.5MM.

Block cutter spacing between adjacent Unit two is 4MM, and two block cutter spacings in the same unit are 5MM.

The usefulness of technique scheme is:

Increase is provided with the block cutter in main serrated knife both sides in the present invention, and the serrated knife line that punching out is come out can't further extend and break because the existence of block line stops the serrated knife line to extend to break and extends to the block line position at most.The existing serrated knife line of accomplishing with 180 ° amplitude doubling punching out, as can be seen from Figure 6, the end product quality of reflector plate is greatly improved.

The specific embodiment

Combine accompanying drawing and embodiment that the present invention is described at present.

A kind of reflector plate serrated knife as shown in Figure 4; It is consecutively arranged to form by one group of serrated knife unit interval, and described serrated knife unit is made up of a main serrated knife 2 and two block cuttves 3, and two block cuttves 3 are arranged at intervals at main serrated knife 2 both sides respectively; Described block cutter 3 facewidth A are 0.2-2MM; The best facewidth is 0.5MM, and the space D of block cutter and main serrated knife is 0.2-3MM, and optimal spacing is 0.5MM.Two block cuttves 3 are vertically installed in main serrated knife 2 left and right sides respectively.With the block cutter spacing C between adjacent Unit two is 1-6MM, and optimal spacing is 4MM, and the doubling of operation serrated knife line is easier, is 1-6MM with two block cutter spacing B in the same unit, and optimal spacing is 5MM, can limit the Breadth Maximum that serrated knife line 21 breaks.

Serrated knife line die sinking figure as shown in Figure 5,3 punching out of block cutter go out

block line

31,2 punching out of main serrated knife go out serrated knife line 21.Because of being provided with the block line, the serrated knife line extends and at most only extends to the block line, and just the Breadth Maximum that breaks of serrated knife line is 5M.
