Description

Technical Field

[0001] The invention belongs to the technical field of high-frequency circuit die-cut parts, and relates to a die-cutting device for high-frequency circuit die-cut parts. Background Art

[0002] In the increasingly competitive die-cutting industry, the unit price of high-frequency circuit materials of the R03010 (R03005) series has increased year by year, which has led to an increasing cost of high-frequency circuit die-cut parts made from these high-frequency circuit materials. In order to ensure price advantages and improve industry competitiveness, the effective utilization of raw materials is a priority issue. The existing high-frequency circuit die-cut parts are arranged too loosely on the material strip. Along the length of the material strip, the spacing between two adjacent high-frequency circuit die-cut parts is 1mm. Although this is convenient for die-cutting, and high-frequency circuit die-cut parts can be die-cut directly on the material strip, there is a lot of scrap left over from the high-frequency circuit materials after die-cutting, resulting in a low utilization rate of raw materials and high production costs. Summary of the invention

[0003] The purpose of the present invention is to provide a die-cutting device for high-frequency circuit die-cut parts in order to overcome the defects of the prior art.

[0004] The purpose of the present invention can be achieved by the following technical solutions:

[0005] A die-cutting device for high-frequency circuit die-cutting parts, the device is used to die-cut high-frequency circuit die-cutting parts on a material strip, the device comprises a first die-cutting unit and a second die-cutting unit arranged in sequence along the moving direction of the material strip, the first die-cutting unit comprises a first upper die seat and a first lower die seat arranged below the first upper die seat, a jump-cut die-cutting mechanism is provided at the bottom of the first upper die seat, the second die-cutting unit comprises a second upper die seat and a second lower die seat arranged below the second upper die seat, and an end die-cutting mechanism is provided at the bottom of the second upper die seat. As the material strip moves, the jump-cutting die-cutting mechanism firstly die-cuts a plurality of high-frequency circuit die-cutting parts on the material strip at intervals, then takes out the die-cut high-frequency circuit die-cutting parts, and the remaining material strip enters the second die-cutting unit, the end die-cutting mechanism performs end die-cutting on the remaining part of the material strip after the jump-cutting, and then the end die-cutting high-frequency circuit die-cutting parts can be taken out.

[0006] Furthermore, the high-frequency circuit die-cutting piece includes a short side, a long side, and a first arc side and a second arc side respectively arranged between the short side and the long side, and the short side is parallel to the long side. The short side, the first arc side, the long side, and the second arc side form the outer edge of the high-frequency circuit die-cutting piece. A plurality of high-frequency circuit die-cutting pieces are arranged on the material strip along the length direction of the material strip, and the short sides and long sides of two adjacent high-frequency circuit die-cutting pieces are collinear, that is, the plurality of high-frequency circuit die-cutting pieces are closely attached to each other, and the spacing between two adjacent high-frequency circuit die-cutting pieces is 0, so as to make full use of the raw materials.

[0007] Furthermore, the jump-cut die-cutting mechanism includes a first peripheral die-cutting knife and a second peripheral die-cutting knife arranged in parallel at the bottom of the first upper die base, and a gap is provided between the first peripheral die-cutting knife and the second peripheral die-cutting knife. The first peripheral die-cutting knife and the second peripheral die-cutting knife are adapted to the peripheral edge of the high-frequency circuit die-cutting piece, and can die-cut a plurality of high-frequency circuit die-cutting pieces at intervals on the material strip.

[0008] Furthermore, the spacing between the first peripheral die-cutting knife and the second peripheral die-cutting knife is equal to the width of the high-frequency circuit die-cutting piece. The width of the high-frequency circuit die-cutting piece is the spacing between the short side and the long side. There is a high-frequency circuit die-cutting piece product gap between the first peripheral die-cutting knife and the second peripheral die-cutting knife. The first die-cutting unit die-cuts the 1st, 3rd, 5th, 7th... high-frequency circuit die-cutting pieces on the material strip, then takes out the 1st, 3rd, 5th, 7th... (odd number) high-frequency circuit die-cutting pieces, and the second die-cutting unit die-cuts the 2nd, 4th, 6th, 8th... (even number) high-frequency circuit die-cutting pieces from the remaining part after jump cutting on the material strip.

[0009] Furthermore, a positioning hole punch is provided at the bottom of the first upper die seat, and the positioning hole punch can die-cut a positioning hole on the material strip to facilitate the positioning of the material strip in the second die-cutting unit.

[0010] Furthermore, the end die-cutting mechanism comprises a first arc-edge end die-cutting knife and a second arc-edge end die-cutting knife which are relatively arranged at the bottom of the second upper die seat. The first arc-edge end die-cutting knife and the second arc-edge end die-cutting knife cooperate with each other to die-cut the remaining part after jump cutting on the material strip into the second, fourth, sixth, eighth, ... high-frequency circuit die-cutting parts.

[0011] Furthermore, the first arc edge end die cutting knife is provided with a first arc edge cutting edge matched with the first arc edge, and the second arc edge end die cutting knife is provided with a second arc edge cutting edge matched with the second arc edge. Since the short sides and long sides of the second, fourth, sixth, eighth, ... high-frequency circuit die cutting pieces have been cut out by the jump-cut die cutting mechanism in the first die cutting unit, in the second die cutting unit, only the first arc edge cutting edge and the second arc edge cutting edge are needed to cut out the first arc edge and the second arc edge at both ends of the second, fourth, sixth, eighth, ... high-frequency circuit die cutting pieces.

[0012] Furthermore, a trocar is provided at the bottom of the second upper die base, and the trocar cooperates with the positioning hole on the material strip to facilitate the positioning of the material strip in the second die-cutting unit.

[0013] When the present invention is actually applied, as the material strip moves, the jump-cut die-cutting mechanism first die-cuts the 1st, 3rd, 5th, 7th ... high-frequency circuit die-cut pieces at intervals on the material strip, and then takes out the 1st, 3rd, 5th, 7th ... high-frequency circuit die-cut pieces that have been die-cut, and the remaining material strip enters the second die-cutting unit, and the end die-cutting mechanism performs end die-cutting on the remaining part of the material strip after the jump-cutting, and die-cuts the 2nd, 4th, 6th, 8th ... high-frequency circuit die-cut pieces, and then the 2nd, 4th, 6th, 8th ... high-frequency circuit die-cut pieces after the end die-cutting can be taken out.

[0014] Compared with the prior art, the present invention has the following characteristics:

[0015] 1) Change the original loose arrangement of high-frequency circuit die-cut parts on the material strip to a close arrangement, so that the spacing between two adjacent high-frequency circuit die-cut parts is 0, so as to make full use of the raw materials, reduce the scraps of high-frequency circuit materials after die-cutting, improve the utilization rate of raw materials, and reduce production costs;

[0016] 2) First, the jump-cut die-cutting mechanism in the first die-cutting unit is used to die-cut the 1st, 3rd, 5th, 7th ... high-frequency circuit die-cut parts at intervals on the material strip, and then the end die-cutting mechanism in the second die-cutting unit is used to die-cut the 2nd, 4th, 6th, 8th ... high-frequency circuit die-cut parts on the remaining part after jump-cutting on the material strip, thereby realizing the die-cutting and forming of the high-frequency circuit die-cut parts under the condition of close arrangement, avoiding the deformation, damage and dimensional deviation that may occur when two adjacent high-frequency circuit die-cut parts on the material strip are die-cut at the same time, thereby improving the quality of the product.
