Description

Hold the decompressor of pole

Technical field

Cell art is the utility model is related to, more particularly to a kind of decompressor of end pole.

Background technology

In battery manufacturing field, end pole is very important parts in battery product, holds the electric conductivity of pole straight Connecing influences the performance of whole battery, such as Fig. 1, and end pole 7 is enclosed on outside copper core 702 by lead overcoat 701 and formed, lead overcoat 701 with Degree of being engaged between copper core 702 directly affects the electric conductivity of end pole 7, the end pole prepared according to usual technique 7, the degree of being engaged between copper core 702 and lead overcoat 701 is not good enough, often influences the yield of the product of end pole 7；In addition, Subsequent technique is needed by fixing end pole 7 and pole group in the end outside encapsulating of pole 7, due to holding the lateral wall of pole 7（That is lead Overcoat 701）Lateral wall smoother, glue therewith bond after twisting resistance it is smaller, easily cause hold pole 7 come off.

Utility model content

Purpose of utility model：For problems of the prior art, the utility model provides a kind of punching press of end pole Device, in the end pole after its punching press, the consistency of lead overcoat is higher, and the degree of being engaged between copper core and lead overcoat is more It is good, electric conductivity is improved, and can effectively lift the twisting resistance after glue bonds with end pole.

Technical scheme：The utility model provides a kind of decompressor of end pole, including base, sample base, push rod, First hydraulic cylinder, second hydraulic cylinder and controller, the sample base are fixed on the base, are set in the sample base Put the sample cell run through on four sides up and down；One end of the push rod is scalable to be connected in the base, and the other end is extend into Below the sample cell in through hole, and the push rod is coaxially disposed with the lower section through hole；The punch rod of the first hydraulic cylinder It is coaxially disposed in the PATENT left side via of the sample cell and with the PATENT left side via, the punch rod of the second hydraulic cylinder is located at Be coaxially disposed in the right side through hole of the sample cell and with the right side through hole, the end of the punch rod of the first hydraulic cylinder with The end of the punch rod of the second hydraulic cylinder is the arcuate structure for coordinating punching press with pole lateral wall in end to be punched, and the arc The outside of shape structure sets multiple punching press projections；The controller respectively with the push rod, the first hydraulic cylinder and described Two hydraulic cylinders electrically connect.

Further, the decompressor of described end pole also includes locking depression bar, sample described in the locking depression bar face The top through hole of product groove sets and is coaxially disposed with the top through hole, and the locking depression bar electrically connects with the controller.

Preferably, the locking depression bar is coaxially oppositely arranged with the push rod.

Preferably, the punch rod of the punch rod of the first hydraulic cylinder and the second hydraulic cylinder is coaxially oppositely arranged.

Beneficial effect：In the utility model, after end pole to be punched is put into sample cell, the punch rod phase of both sides Extruded to the both sides side wall of mobile opposite end pole, due to the multiple projections of the end set of punch rod, so the end after punching press Pole both sides outer wall can just form multiple stamped recess, due to the extruding by both sides punch rod so that in the pole of end Lead jacket structure is finer and close, and the fitness between copper core and lead overcoat is more preferable, further, since the generation of above-mentioned stamped recess, When so that subsequently end pole is fixed with pole group by encapsulating, glue can enter in stamped recess, so as to effectively increase glue Water comes off with the twisting resistance after the pole bonding of end, anti-not-go-end pole, rate of reducing the number of rejects and seconds.

Embodiment

The utility model is described in detail below in conjunction with the accompanying drawings.

Present embodiments provide for a kind of decompressor of end pole, as shown in Fig. 2 mainly by base 1, sample base 2, Push rod 3, first hydraulic cylinder 4, second hydraulic cylinder 5, locking depression bar 8 and controller 6 form, and sample base 2 is fixed on base 1 On, the sample cell 202 run through on four sides up and down, the top through hole of locking depression bar 8 and sample cell 201 are set in sample base 2 It is coaxially disposed and the surface of through hole above, the lower section through hole of push rod 3 and sample cell 201 is coaxially disposed and led to positioned at lower section In hole, locking depression bar 8 is coaxial with push rod 3 and is oppositely arranged；The punch rod of first hydraulic cylinder 4 and the PATENT left side via of sample cell 201 It is coaxially disposed and in PATENT left side via, the punch rod 501 of second hydraulic cylinder 5 is coaxially disposed with the right side through hole of sample cell 201 And in the through hole of right side, the punch rod of first hydraulic cylinder 4 is coaxial with the punch rod 501 of second hydraulic cylinder 5 and is oppositely arranged；The The punching press boom end of one hydraulic cylinder 4 is the arcuate structure 502 for coordinating punching press with the lateral wall of end pole 7 to be punched, and the arc knot The outside of structure 502 sets multiple punching press projections 503, and such as Fig. 3, controller 6 is respectively with locking depression bar 8, first hydraulic cylinder 4, second Hydraulic cylinder 5 and push rod 3 electrically connect, the operation for control.
