Abstract
The utility model relates to a punch of a metal coil micro-bur punching device, wherein the cutting side of the punch is in a circular arc shape, and the lateral face of the punch is provided with 6-10 cutting points. Compared with the prior art, the punch can match with a punching die, the punching device can be used to punch ultra-thin broadband copper or aluminum foil net metal coil micro burs of polymer lithium ion secondary batteries with large capacity, when metal coils are punched, pressure slowly increases from the middle of the punch to the periphery, a cutting edge formed by the cutting side is sharp, metal scraps punched can be easily removed from the punch, and a structure which is punched is more accurate.
Description
Technical field
The utility model relates to a kind of drift of hole punched device, especially relates to a kind of drift of metal coil tape microtriche thorn hole punched device.
Background technology
Lithium ion battery has specific energy density height, memoryless property, advantage such as pollution-free, has obtained extensive use at mobile phone, portable gamma camera, notebook computer, electric automobile etc.But, because lithium ion battery adopts organic liquid to do electrolyte, there is leakage, catches fire, potential safety hazard such as blast, adopting polymer to make electrolyte can effectively address these problems.Polymer Li-ion battery adopts polymer to replace the secondary cell of liquid electrolyte as electrolyte just, but have advantages such as thin typeization, arbitrary areaization and arbitrary shapeization, can not produce problems such as leakage, burning, blast, adopt plastic-aluminum combined thin film fabrication battery container, improve the specific capacity of entire cell greatly; In addition, use lithium metal greatly to improve battery capacity as negative pole.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.In existing copper, the aluminum foil web punch process, carry out at the normal punching angle of 90 degree of adopting, downside at wire netting is prone to burr phenomena, 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.How to design punch structure, realize that the microtriche thorn punching of metal winding is a problem demanding prompt solution.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of waste material to remove easily, cut the drift of metal coil tape microtriche thorn hole punched device accurately for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of drift of metal coil tape microtriche thorn hole punched device is characterized in that the cutting edge of described drift is a circular arc, and the side of drift comprises 6-10 cut point.
The punching angle of described cutting edge is less than 60 °.
Described cut point is the shape of falling the mountain peak that peak value is a circular arc.
Compared with prior art, the utility model can be used with punching die, use this decompressor can realize to high capacity polymer lithium rechargeable battery ultra-thin breadth copper, the punching of aluminum foil web metal coil tape microtriche thorn, when metal coil tape is carried out punching press, pressure slowly increases to the neighboring area in the middle of drift, the blade that cutting edge forms is sharp-pointed, and the metal debris of being gone out can be removed from drift easily, and the structure that punches out is also more accurate.
Description of drawings
Fig. 1 is a drift cutting edge schematic diagram among the embodiment 1;
Fig. 2 is the side view of drift among the embodiment 1.
1 is the circular arc cross section among the figure, and 2 are the punching angle, and 3 is cut point.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
A kind of drift of metal coil tape microtriche thorn hole punched device, the cutting edge of this drift is a circular arc, and the punching angle of cutting edge is less than 60 °, and as shown in Figure 1, the side of drift comprises 7 cut points, and cut point is the shape of falling the mountain peak that peak value is a circular arc, as shown in Figure 2.
The circular arc cross section 1 in cutting edge zone makes punching angle 2 become sharply, and the material of going out like this can be got rid of easily, reduces the formation of punching burr greatly.When the winding of drift stamped metal, in the middle of at first acting on, pressure has on the cut point 3 of minimum, both sides cut point 3 penetrates in the stamping material successively in succession then, when drift passes the metal winding, the drift mid portion takes the lead in scrap metal is flushed to down in the nib, waste material is easy to be excluded like this, improves cutting usefulness and punching quality greatly.
Be distributed in this punch structure on the upper mould fixed plate in groups, form a cover hole punched device with mould bases, upper mould fixed plate, lastics plate, concave template, lastics device, guide plate, pressure apparatus, step device and unwinding and rewinding device, under the stepping of equipment and pressure, realize to thickness being that 5-50 μ m, width 4-550mm, aperture are the super thin metal roll coil of strip group hole microtriche thorn cold punching at a high speed of 0.3-3.0mm.
A kind of drift of metal coil tape microtriche thorn hole punched device, the cutting edge of this drift is a circular arc, and the punching angle of cutting edge is less than 60 °, and the side of drift comprises 6 cut points, and cut point is the shape of falling the mountain peak that peak value is a circular arc.
The circular arc cross section in cutting edge zone makes the punching angle become sharply, and the material of going out like this can be got rid of easily, reduces the formation of punching burr greatly.When the winding of drift stamped metal, in the middle of at first acting on, pressure has on the cut point of minimum, both sides cut point and cutting edge penetrate in the stamping material successively in succession then, when drift passes the metal winding, the drift mid portion takes the lead in scrap metal is flushed to down in the nib, waste material is easy to be excluded like this, improves cutting usefulness and punching quality greatly.
