Abstract

The utility model is related to a kind of LB patches ladder die cutting dies to protect knife system, including lower knife plate, lower knife plate includes the high punching edge of a knife, the low punching edge of a knife, location hole and punching edge of a knife knife line with the limit protrusion of exterior domain, the height punching edge of a knife, the low punching edge of a knife is the bimodal edge of a knife, the height punching edge of a knife is connect with low punching edge of a knife head and the tail, form a closed loop, junction is stepped, closed loop shape is punched the LB products detached with needs and is adapted to, the difference in height of the height punching edge of a knife and the low punching edge of a knife is 1~1.5 times of PET film thickness, the height of limit protrusion 0.3~0.5 PET film thickness lower than the low punching edge of a knife, height punching edge height is 1.1mm, the height of the low punching edge of a knife is 1mm, the height of limit protrusion is 0.7mm.The utility model can play the punching depth of the upper knife plate of hardness limitation, avoid the problem that because be punched it is too deep lead to that PET film is punched through or cutting die gets stuck and occurs, to ensure the qualification rate and production efficiency of product.

Description

LB patch ladder die cutting dies protect knife system

Technical field

The utility model is related to LED production equipments, particularly relate to a kind of LB patches ladder die cutting die shield knife system.

Background technology

For LB patch products when entering clicking technique, used die cutting die is typically to be set by tool parameters Its punching depth is controlled, due to the precision problem of gearing structure, this control mode is often difficult to control its punching depth Precision, often there is a situation where be punched it is too deep cause that PET film is punched through or product card is on cutting die, if being stuck in cutting die On, and need that working hour is spent to go to take out product from cutting die, influence the qualification rate and production efficiency of product.

Invention content

The utility model provides a kind of LB patches ladder die cutting die shield knife system, to overcome existing LB patches blanking die There is a situation where that punching is too deep and cause that PET film is punched through or product card is on cutting die, the qualification rate and production for influencing product are imitated The problem of rate.

The utility model adopts the following technical solution：

LB patch ladder die cutting dies protect knife system, including lower knife plate, and lower knife plate includes the high punching edge of a knife, low punching cutter Mouthful, location hole and in punching edge of a knife knife line with the limit protrusion of exterior domain, the height punching edge of a knife, the low punching edge of a knife are bimodal knife Mouthful, the high punching edge of a knife is connect with low punching edge of a knife head and the tail, forms a closed loop, and junction is stepped, closed loop shape and needs It is punched the LB products adaptation of separation, the height punching edge of a knife and the low difference in height for being punched the edge of a knife are 1~1.5 times of PET film thickness, limit Height 0.3~0.5 PET film thickness lower than the low punching edge of a knife of position protrusion.

Further：

Above-mentioned high punching edge height is 1.1mm, and the height of the above-mentioned low punching edge of a knife is 1mm, the height of above-mentioned limit protrusion Degree is 0.7mm.

Above-mentioned location hole includes 4 a diameter of 3 positioning pin nail hole, 6 a diameter of 2 dowel holes.

Above-mentioned high punching cutter choma around region be square.

By the above-mentioned description to the utility model structure it is found that compared to the prior art, the utility model has following excellent Point：The LB patch ladder die cutting dies of the utility model protect knife system, are equipped with the high punching edge of a knife, low two kinds of punching cutters of the punching edge of a knife Limit protrusion is arranged in mouth and the region other than the knife line that height is punched the edge of a knife, the low punching edge of a knife, which can play The punching depth of the upper knife plate of hardness limitation, avoid the problem that because be punched it is too deep lead to that PET film is punched through or cutting die gets stuck and occurs, To ensure the qualification rate and production efficiency of product.

Description of the drawings

Fig. 1 is the structural schematic diagram that the utility model LB patch ladder die cutting dies protect knife system.

Fig. 2 is that the utility model LB patch ladder die cutting dies protect structural schematic diagram of the knife system at A-A.

Specific implementation mode

Illustrate specific embodiment of the present utility model with reference to the accompanying drawings.

Referring to Fig.1, Fig. 2, LB patch ladder die cutting die protect knife system, including lower cutting die 1, and lower cutting die 1 includes high is punched The edge of a knife 11, the low punching edge of a knife 12, location hole 13 and in punching edge of a knife knife line with the limit protrusion 14 of exterior domain, the height punching edge of a knife 11, the low punching edge of a knife 12 is the bimodal edge of a knife, and 12 mouthfuls of head and the tail of the height punching edge of a knife 11 and low punching cutter are connect, and form a closed loop, Junction is stepped, and closed loop shape is punched the LB products detached with needs and is adapted to, the height punching edge of a knife 11 and the low punching edge of a knife 12 difference in height is 1~1.5 times of PET film thickness, and the height of limit protrusion 14 is than 12 low 0.3~0.5 PET of the low punching edge of a knife Film thickness；The highly preferred height punching edge of a knife 11 is 1.1mm, and the highly preferred of the low punching edge of a knife 12 is 1mm, the height of limit protrusion 14 Degree is preferably 0.7mm, which can play the punching depth of the upper knife plate of hardness limitation, avoid because being punched too deep cause The problem of PET film is punched through or cutting die gets stuck occurs, to ensure the qualification rate and production efficiency of product.Location hole 13 includes 4 The dowel hole 132 of a a diameter of 3 positioning pin nail hole 131,6 a diameter of 2.The circular region of the height punching edge of a knife 11 is four directions Shape.

The above is only the specific embodiments of the present invention, but the design concept of the present invention is not limited thereto, All non-essential modifications to the present invention made by this concept should all belong to the row for invading scope of protection of the utility model For.
