The utility model content
The purpose of the utility model is to overcome the weak point of prior art; And a kind of pole piece and lug are provided is one; Can improve reliability of products and uniformity; Also can guarantee the uniformity of pole piece thickness simultaneously, greatly make things convenient for production, improve a kind of battery pole ear building mortion of properties of product.
A kind of battery pole ear building mortion; Its structural feature is: comprise two groups moving knife and quiet cutter; Moving knife and quiet cutter are set up in parallel in pairs, and the distance between two groups of sound cuttves equals the width of a lug, and the length sum of two groups of moving knife is more than or equal to the distance between the adjacent lug; Each moving knife is made up of two branch cutting blades that surround groove shape; Each divides the blade of cutting blade to be angled construction, and the one side at angle conforms to a side edge shape of lug, and the bottom land shape-consistent between the another side at angle and the adjacent lug, described moving knife are driven by drive unit and do linear reciprocating motion.
The battery pole ear building mortion of this structure, the tinsel exposed area at pole piece base material edge is filled in two groups sound blade in when work between, drive moving knife work; The sound cutter of each group is sheared from the both sides of lug respectively, and the formed space, interval between two groups of sound blades is lug, also shears out part or all of bottom land simultaneously; After the shaping release; The pole piece tape running pauses movable cutter set work in the position that the next one need be shaped; The lug that shearing makes new advances also is shaped bottom land, and a plurality of lugs so repeatedly just can be shaped on pole piece.
The length sum of two groups of moving knife can guarantee to cut into smoothly needed shape more than or equal to the distance between the adjacent lug.
Adopt two fens cutting blades of breakaway-element to constitute the moving knife of each group; Help moving knife like this and quiet cutter is fitted fully, help eliminating because of mismachining tolerance, use the fit clearance of the moving knife that factor caused such as abrasion and quiet cutter, guarantee that it is the overall process shear history that moving knife cuts lug; Help controlling shearing defectives such as shear burr; Can significantly improve cutter life, cutting die significantly reduces the cutting die cost as long as changing moving knife just can produce again simultaneously.
Described battery pole ear building mortion also includes moving knife guiding mould; The blade of described moving knife is done straight reciprocating motion along moving knife guiding mold cavity; Described moving knife guiding mould is arranged at the top of quiet cutter, between quiet cutter and moving knife guiding mould, is provided with and holds the gap that pole piece passes through.
Moving knife guiding mould is set in building mortion, but the action of precise guidance moving knife, thus guarantee the accuracy sheared.
Described guiding mould inwall is provided with convex tendon.
Inwall at the guiding mould is provided with convex tendon, makes the inwall concave-convex surface structure of guiding mould, helps the trouble-free operation of moving knife.
The convex tendon of described guiding mould inwall is arranged on the jointing positions of two moving knife on the guiding mould and the corner on the moving knife.
Be provided with the gap between the blade of described quiet cutter and the guiding mould convex tendon.
Between the blade of quiet cutter and guiding mould convex tendon, the gap is set, does shearing motion when guaranteeing that moving knife moves downward and between the quiet cutter.
The gap that is provided with between the blade of described quiet cutter and the guiding mould convex tendon is 50 microns to 0.2 bold and unconstrained meter.
Described moving knife is installed on the moving knife holder through the flexible adjustment device, and the flexible adjustment device is pressed in moving knife on the moving knife guiding mould.
Cutting blade is installed on the moving knife holder through the flexible adjustment device, does not have the gap between moving knife and the quiet cutter in the time of so just can guaranteeing to shear, guarantee the quality of shearing.
Described flexible adjustment device is that spring constitutes, and an end of spring is supported on the moving knife holder, and the other end is supported on the moving knife.
The guiding mould is provided with and is used to guide moving knife to do the guide rail of straight reciprocating motion.
On the guiding mould, guide rail is set, can improves the motion accuracy of moving knife.
Described guide rail is a journal bearing.
Be provided with the gap between the branch cutting blade of each group moving knife two symmetric arrays.
Be provided with the gap between two fens cutting blades, can prevent that two fens cutting blades from interfering, so that process required lug smoothly.
The blade intersection of each component cutting blade is for being staggered.
Being staggered of the blade of the branch cutting blade of two symmetric arrays can guarantee the integrality of cutting.
Each blade that divides cutting blade for be from that side identical to that side identical with the bottom land shape with lug by the end to high gradient tendency, near quiet cutter the time with moving knife on lug identical that side tool sword first near quiet cutter.The moving knife of this structure when shearing, is inwardly sheared by the edge of pole piece gradually.
Being staggered of two transfer knife-blade extends to another minute cutting blade place and cover a bit of of another minute cutting blade for the blade of one fen cutting blade wherein; Another minute, cutting blade that a part of blade of being in intersection was that the edge is high, the gradient tendency that then drops gradually inward.
Drive that moving knife is made the drive unit of linear reciprocating motion or for hydraulic cylinder or for cylinder etc.
Described moving knife holder is installed on the upper connective plate.
In sum, the utility model is compared the following advantage of prior art:
