Abstract
The utility model discloses a mesh cold-punching mold for metal ban scroll high-speed meshes. The mold takes on the shape of a plum blossom, the center of the mesh is a round section, the outer part of a circle comprises eight outward triangular grooves, and the vertical section takes on the shape of an inverted horn along the depth direction. Compared with the prior art, the mesh cold-punching mold has convenient spurt, can lead waste material generated in punching to drop in the holes of a lower mold plate in time, and greatly increase the friction force between a punch and the waste material; and punched waste material is extremely and easily separated from the punch.
Description
Technical field
The utility model relates to a kind of mould, especially relates to a kind of metal coil tape group hole cold punching mesh mould at a high speed.
Background technology
Polymer Li-ion battery has series of advantages such as specific energy height, pollution-free, safe, memoryless property, life-span are long, shape can be changed arbitrarily, is that the ideal of secondary energy sources one of is selected.The positive electrode part of polymer Li-ion battery is behind the wire netting face coat, through super-dry, the step of pressing, cutting and cutting realizes.Powder in existing copper, the aluminum foil web punch process, produces a large amount of powders, if can not in time be got rid of, can produce impression to the wire netting surface, burr phenomena occur, the existence of burr, influence the wire netting quality greatly, very easily cause battery short circuit, have a strong impact on battery performance.The annual expensive multi-billion dollar of the government of American-European countries and enterprise is used to solve the Burr Problem of battery metal net.It is common that what adopt towards net equipment lower bolster is the casement of regular shape, because nib regular shape, frictional force are little, the powder of accumulation is very easily followed punching pin and is gone out the nib working face in the nib, in addition, if the waste material of accumulation is too much in the nib, card pin phenomenon appears easily, can cause when serious to fracture towards pin, replacing is wasted time and energy towards pin, influences speed of production.How can break through existingly towards the network process technical bottleneck, in time get rid of waste material, realize microtriche thorn wire netting, be a problem demanding prompt solution.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of spurt convenient for the defective that overcomes above-mentioned prior art existence, reduces the metal coil tape high speed group hole cold punching mesh mould that waste material is piled up.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of metal coil tape is group hole cold punching mesh mould at a high speed, it is characterized in that described mould is the plum blossom shape, and mould central authorities are circular cross-section, also comprise 8 outside triangular grooves in the outside of circle.
Described mould vertical section is the inverted tubaeform shape along depth direction.
Compared with prior art, the utility model spurt is convenient, and the waste material that produces in the time of can making punching in time falls in the lower bolster nib, and increases the frictional force of drift and salvage department greatly, and the waste material of going out very easily breaks away from drift.
Description of drawings
Fig. 1 is the cross sectional representation of mould among the embodiment 1;
Fig. 2 is the vertical section schematic diagram of mould among the embodiment 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment 1
A kind of metal coil tape is group hole cold punching mesh mould at a high speed, its cross section as shown in Figure 1, vertical section as shown in Figure 2, the hole of mould is the plum blossom shape, and central authorities are circular cross-section, also comprise 8 outside triangular grooves in the outside of circle, vertical section is the inverted tubaeform shape along depth direction, can be 5 μ m to thickness, width be 4mm, and the aperture is that the super thin metal winding of 0.3mm realizes microtriche thorn group hole cold punching at a high speed.During to copper, the punching of aluminum foil metal band, metal tape is placed between cope match-plate pattern and the lower bolster, pass the pin hole of cope match-plate pattern towards pin, align, when metal tape is dashed when wearing with the mould of lower bolster, the a large amount of waste materials that produce, enter in the hole of lower bolster mould, because mould is horn-like along depth direction, waste material is easy to come off along the die depth direction, the amount of waste material that overstocks in the mould be can significantly reduce like this, card pin and broken needle phenomenon avoided effectively.Mould irregularly shaped increased greatly towards the frictional force of pin and salvage department, and when when pin breaks away from the mould of lower bolster, waste material is easy to break away from towards pin, can not follow towards pin and go out working face, can not cause impression to product.
Embodiment 2
A kind of metal coil tape is group hole cold punching mesh mould at a high speed, the hole of mould is the plum blossom shape, central authorities are circular cross-section, also comprise 8 outside triangular grooves in the outside of circle, vertical section is the inverted tubaeform shape along depth direction, can be 10 μ m to thickness, width be 100mm, and the aperture is that the super thin metal winding of 1.0mm realizes microtriche thorn group hole cold punching at a high speed.During to copper, the punching of aluminum foil metal band, metal tape is placed between cope match-plate pattern and the lower bolster, pass the pin hole of cope match-plate pattern towards pin, align, when metal tape is dashed when wearing with the mould of lower bolster, the a large amount of waste materials that produce, enter in the hole of lower bolster mould, because mould is horn-like along depth direction, waste material is easy to come off along the die depth direction, the amount of waste material that overstocks in the mould be can significantly reduce like this, card pin and broken needle phenomenon avoided effectively.Mould irregularly shaped increased greatly towards the frictional force of pin and salvage department, and when when pin breaks away from the mould of lower bolster, waste material is easy to break away from towards pin, can not follow towards pin and go out working face, can not cause impression to product.
Embodiment 3
A kind of metal coil tape is group hole cold punching mesh mould at a high speed, the hole of mould is the plum blossom shape, central authorities are circular cross-section, also comprise 8 outside triangular grooves in the outside of circle, vertical section is the inverted tubaeform shape along depth direction, can be 50 μ m to thickness, width be 550mm, and the aperture is that the super thin metal winding of 3.0mm realizes microtriche thorn group hole cold punching at a high speed.During to copper, the punching of aluminum foil metal band, metal tape is placed between cope match-plate pattern and the lower bolster, pass the pin hole of cope match-plate pattern towards pin, align, when metal tape is dashed when wearing with the mould of lower bolster, the a large amount of waste materials that produce, enter in the hole of lower bolster mould, because mould is horn-like along depth direction, waste material is easy to come off along the die depth direction, the amount of waste material that overstocks in the mould be can significantly reduce like this, card pin and broken needle phenomenon avoided effectively.Mould irregularly shaped increased greatly towards the frictional force of pin and salvage department, and when when pin breaks away from the mould of lower bolster, waste material is easy to break away from towards pin, can not follow towards pin and go out working face, can not cause impression to product.
