Abstract

The invention relates to a cutting-off chamfering die for a lithium-ion battery pole lug. The cutting-off chamfering die comprises a base, a concave and convex type vertical cutter die set, a pole lug rubber cutting-off cutter set, positioning pins and guide rods. The base is divided into an upper layer and a lower layer which are connected through the guide rods; the concave and convex type vertical cutter die set comprises an upper cutter die and a lower cutter die, wherein the upper cutter die is a rectangular male die with four round corners, and is arranged on the lower surface of the upper layer of the base, and the lower cutter die is a female die in a corresponding shape and is arranged at the corresponding position of the lower layer of the base; the pole lug rubber cutting-off cutter set is divided into an upper cutting-off portion and a lower cutting-off portion, the upper cutting-off portion is a piece-shaped male die and is arranged on the lower surface of the upper layer of the base, and the lower cutting-off portion is a strip-shaped female die and is arranged at the corresponding position of the lower layer of the base; and the positioning pins are arranged between the concave and convex type vertical cutter die set and the pole lug rubber cutting-off cutter set and are used for positioning the position of the pole lug. The cutting-off chamfering die is easy to operate; and a plurality of working procedures are integrated, one plate pole lug can be machined at a time, and therefore the production efficiency is greatly improved.

Description

A kind of cut-out rounding mould of lithium ion power battery pole ear
Technical field
Lithium ion power battery pole ear manufactures field, particularly relates to a kind of cut-out rounding mould of lithium ion power battery pole ear.
Background technology
Lithium ion power battery pole ear is greater than the metallic aluminium/nickel of 0.1mm by tab and thickness or nickel-clad copper forms.Lug will cut off according to client's dimensional requirement and carry out rounding processing to four end angles after cutting off after hot press heat-sealing is shaping, existing method first the head end of a plate ear is cut redundance by dimensional requirement by manual or Pneumatic cutter, again the other end is cut redundance on request, on request conductor both sides tab is pressed ear size requirements excision redundance respectively again, then remove and protect PET up and down, put into rounding mould punching chamfering, have following drawback like this: 1, operating efficiency is low; 2, the fraction defective manually caused is higher; 3, multiple operation causes tab bad order, easily causes conductive surface to scratch and frays; 4, dimensional uniformity is bad even overproof; 5, because of the use of electrokinetic cell lug is all soft state metal, and the section of hand-powered cutter or Pneumatic cutter has flange situation.
Summary of the invention
The present invention is directed to the deficiency that present technique exists, the invention provides a kind of cut-out rounding mould of lithium ion power battery pole ear, this device is simple to operate; Collect multiple operation to complete in a procedure, and once can process a plate ear, substantially increase production efficiency.
The present invention is for solving the problems of the technologies described above by the following technical solutions:
A cut-out rounding mould for lithium ion power battery pole ear, comprises base, lenticular upper lower cutter module, tab cutoff tool group, alignment pin and guide post; Described base is divided into two-layer up and down, connected by guide post, described lenticular upper lower cutter mould splits is upper cutter mould and incision cutting die, the rectangle punch of described upper cutter mould to be four angles be fillet, it arranges on the lower surface on the upper strata of base, incision cutting die is the die of respective shapes, is arranged on the relevant position of base lower floor; Described tab cutoff tool group is also divided into upper and lower cutting portion, and described upper cutting portion is sheet punch, is arranged on the lower surface on the upper strata of base, and described lower cutting portion is bar shaped die, is arranged on the relevant position of base lower floor; Described alignment pin is arranged between lenticular upper lower cutter module, tab cutoff tool group, for locating lug position.
This mould also comprises buffering foam cushion, and described buffering foam cushion is arranged on the upper surface of base lower floor.
Described guide post is also wound with back-moving spring.
Described lenticular upper lower cutter module comprises two groups of upper cutter moulds and incision cutting die.
The present invention adopts above technical scheme compared with prior art, has following technique effect:
Compared with prior art, new die cutting die is adopted to be cut off by lug, rounding once completes, and once can process a plate ear, greatly improve production efficiency, reduce fraction defective, product size uniformity improves greatly, cut off corner without flange and burr, decrease lug surface and scratch the probability frayed.
Accompanying drawing explanation
Fig. 1 is the structural representation of the cut-out rounding mould of lithium ion power battery pole ear of the present invention;
Wherein, 1-base, 2-upper cutter mould, 3-incision cutting die, 4-alignment pin, 5-guide post, 6-back-moving spring.
Detailed description of the invention
The invention provides a kind of cut-out rounding mould of lithium ion power battery pole ear, for making object of the present invention, clearly, clearly, and the present invention is described in more detail with reference to accompanying drawing examples for technical scheme and effect.Should be appreciated that concrete enforcement described herein is only in order to explain the present invention, is not intended to limit the present invention.
Be described in detail below in conjunction with the technical scheme of accompanying drawing to invention:
The cut-out rounding mould of this lithium ion power battery pole ear disclosed by the invention, its structure as shown in Figure 1, comprises base 1, lenticular upper lower cutter module, tab cutoff tool group, alignment pin 4 and guide post 5; Described base 1 is divided into two-layer up and down, connected by guide post 5, described lenticular upper lower cutter mould splits is upper cutter mould 2 and incision cutting die 3, the rectangle punch of described upper cutter mould 2 to be four angles be fillet, it arranges on the lower surface on the upper strata of base, incision cutting die 3 is the die of respective shapes, is arranged on the relevant position of base lower floor; Described tab cutoff tool group is also divided into upper and lower cutting portion, and described upper cutting portion is sheet punch, is arranged on the lower surface on the upper strata of base, and described lower cutting portion is bar shaped die, is arranged on the relevant position of base lower floor; Described alignment pin 4 is arranged between lenticular upper lower cutter module, tab cutoff tool group, for locating lug position.
Preferred as one, this mould also comprises buffering foam cushion, and buffering foam cushion is arranged on the upper surface of base lower floor.
Described guide post 5 is also wound with back-moving spring 6.
In the present embodiment, described lenticular upper lower cutter module comprises two groups of upper cutter moulds 2 and incision cutting die 3.
Hot-forming tabular lug removes PET, lug conductor is put into corresponding positioning pin rod respectively, two positioning pin rods are located conductor width, two positioning pin rods are located blob of viscose lower edge, make that whole plate ear is smooth to be put into residing location and cut the electronic little punch press of rear startup, connecting rod drives upper slitter module undershoot to cut off two ends excess conductor and to its rounding, middle blade cuts off tab, and the unnecessary tab in two ends is also cut in the lump simultaneously.
