Detailed Description
In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.
Referring to fig. 1, a cutting die for processing a flexible circuit board according to an embodiment of the present invention includes a die holder 1, a knife surface 10, a cushion block, a positioning hole 104, and a positioning pin 105.
The knife face 10 is arranged in the middle of the die holder 1, the knife face 10 comprises a first knife face 101 and a second knife face, and the first knife face 101 surrounds the whole periphery of the second knife face. In this embodiment, the first blade surface 101 is a rectangular-like structure, and the blade heights of the first blade surface 101 and the second blade surface are the same. The second blade face has a plurality of, the second blade face includes: a "square" blade surface 1021 having a first area and a square blade surface 1022 having a second area, the first area being greater than the second area. In this embodiment, the square blade surface 1022 may be multiple and spaced apart from each other inside the first blade surface 101.
With continued reference to fig. 1 to 3, the pad, specifically an EVA material or high elastic cotton, includes a first pad 1031 and a second pad 1032, the first pad 1031 is disposed and adapted to the inside of the "knife face 1021, the second pad 1032 is disposed and adapted to the inside of the square knife face 1022, and the height of the first pad 1031 is higher than that of the second pad 1032; preferably, the first pad 1031 is higher than the "knife" shaped surface 1021, the cross section of the top end of the first pad 1031 is a trapezoid structure, and the bottom end point of the trapezoid structure is lower than the blade edge of the "knife" shaped surface 1021; the second pad 1032 is a square pad below the edge of the square blade face 1022. The selection of different cushion block shapes is based on the consideration of the area of the knife face, when the area of the knife face is larger, the phenomena of fold or depression and the like are easier to generate, at the moment, the first cushion block is selected, the bevel edge of the trapezoidal section is favorable for punching, and after punching, the raised part can eject the raw material of the circuit board due to the elasticity of the cushion block; the rectangular knife block that is less than the cutting edge is selected when the knife face area is less (the area critical value specifically can be 1 square centimeter), and the reason lies in, the less knife face department of area produces the degree of deformation less, has in the design certain buffering can, square cushion also more easily obtains.
In this example, the second facet further includes a large rectangular facet 1023 having a third area, a small rectangular facet 1024 having a fourth area, and a circular facet 1025 having a fifth area, the third area being larger than the second area, the fourth area and the fifth area both being smaller than the second area, for example, the second area is 1 square centimeter in particular. The large rectangular knife surface 1023 can be matched with a third cushion block, the height of the third cushion block is consistent with that of the first cushion block 1031, meanwhile, the top end section of the third cushion block is also of a trapezoidal structure, and the bottom end point of the trapezoidal structure is lower than the cutting edge of the large rectangular knife surface 1023; the small rectangular tool face 1024 and the circular tool face 1025 are also respectively provided with a fourth cushion block and a fifth cushion block which are matched with each other, and the heights of the fourth cushion block and the fifth cushion block are consistent with those of the second cushion block.
Further, still can be equipped with the sixth cushion of adaptation between the gap of each adjacent second knife face, the height of sixth cushion is unanimous with second cushion 1032, and through addding the cushion, during die-cut, the cushion can be lived the flexible line way board support, makes the flexible line way board can not sink down and lead to the deformation, therefore during die-cut, the fold is difficult to take place for the product, has both guaranteed die-cut precision, also guarantees the quality of product. Meanwhile, the product can be better demoulded and cannot be clamped in a mould, and the working efficiency and the product quality can be improved.
In this embodiment, the positioning holes 104 are disposed on the die holder 1, the positioning holes 104 may be 4 positioning hole groups, the positioning hole groups are respectively disposed around the blade surface 101, each positioning hole group includes a first hole 1041 and a second hole 1042, the aperture of the first hole 1041 is larger than that of the second hole 1042, specifically, for example, the aperture of the first hole 1041 is 4mm, and the aperture of the second hole 1042 is 3 mm; the first hole 1041 and the second hole 1042 in each positioning hole group have different distances, in other words, each positioning hole group includes a first hole 1041 and a second hole 1042 having a distance, and the distances of each positioning hole group in 4 positioning hole groups are different from each other. In addition, the cutting die further comprises a positioning pin 105, the positioning pin 105 is detachably inserted into the positioning hole group, and the positioning pin 105 corresponds to the positioning hole 104. The special design of location punch combination has played and has prevented slow-witted effect, when locating pin 105 and locating hole 104's cooperation, can guarantee the stability of cutting die, need not to counterpoint again at the during operation simultaneously, and the material resources of using manpower sparingly improve work efficiency.
Furthermore, a cross-shaped positioning punch 106 is further disposed on the die holder, and the positioning punch 106 is disposed between the first hole 1041 and the second hole 1042.
Preferably, the blade of the first blade surface 101 in this embodiment is a structure with a straight outside and an inclined inside, and such a design is more suitable for a portion with a large die cutting range, and has a large die cutting force and high precision. Simultaneously, the cutting edge of second knife face selects for interior straight structure (refer to the cutting edge structure that fig. 2 and fig. 3 show) that inclines outward, and such design can make the cutting edge more sharp, not only can carry out better cutting and can also prevent the card material, can also alleviate the inside casing and receive the extrusion and lead to product deformation scheduling problem.
The utility model discloses set up the cushion in each second knife face selectively, the support of cushion makes the production of card material have been avoided to the flexible line way board product, and the phenomenon that raw material plate also is difficult for producing the deformation when die-cut has improved work efficiency simultaneously, has guaranteed to obtain the quality of product.
In addition, in the set positioning hole group, the first hole and the second hole which form each pair of positioning hole groups have different hole diameters, and the distance between the first hole and the second hole is also different, so that the setting has good fool-proofing effect.
