Description

A kind of armature flat copper thread elements knife edge die tool
Technical field
The present invention relates to mould applications, especially a kind of to have for all kinds of armature flat copper thread elements knife edge dies.
Background technique
Currently, well known armature element is divided into two class of circular copper wire and flat type copper wire more, circular copper wire sectional area is smaller, processing Conveniently, technological forming is good, is chiefly used in small power electric armature;Flat copper cross-sectional area is larger, but processing and technological forming are difficult, It is chiefly used in heavy-duty motor armature.For the market demand for meeting heavy-duty motor, when carrying out research and development manufacture to such motor, motor Armature component mostly uses the relatively large flat type copper wire in section.When cutting off to flat type copper wire, on the one hand to guarantee shear sectional plane Impulse- free robustness prevents the excessive armature insulation that punctures of element burr from causing armature puncture short;On the other hand to guarantee armature component without curved Head (song) deformation, prevent element forward line sending when cause the stifled line of equipment to cause to stop production.
But in the actual production process, with the abrasion of cutting edge roundness, section burr becomes larger, and section inconvenience embedding is made Slot insulation is punctured or released at element when embedding, armature puncture short is caused to be scrapped.There is element elbow (song) change after element cutting The problem of shape, causes equipment to block up line after element elbow (song) deformation in line sending, so as to cause halt production, component loss, production effect The problems such as rate is low.
Summary of the invention
In order to overcome armature flat copper thread elements in cutting, the breakdown of the armature due to caused by section burr is big and elbow is short Road and equipment are blocked up the problems such as line stops production, and a kind of present invention high-quality and high-efficiency high life, to be simple to manufacture low-cost armature flat Copper wire element cuts off mold.
The technical scheme adopted by the invention is that: including upper cutoff tool, lower cutoff tool, it is set to upper cutoff tool and lower cutting Postive stop baffle between knife, upper cutoff tool loaded in the mounting groove of upper mounting plate lower surface, install loaded on lower installation board by lower cutoff tool In slot, for lower installation board loaded in mounting seat, mounting seat is equipped with guide post, and upper mounting plate is equipped with guide sleeve, guide post and guide sleeve It cooperates, upper mounting plate is equipped with spring guide pillar straight down, and spring guide pillar lower end is plugged on postive stop baffle;The upper cutting Knife includes upper slitter portions, the upper knife body portion in the middle part of upper slitter portions, and there are upper cutoff tool cutting edge, upper cutoff tool in the upper knife body portion Cutting edge bottom is upper forming surface, and upper cutoff tool cutting edge two sides are side forming surface, and limit is equipped at left and right sides of upper cutoff tool cutting edge For position baffle by bit space, the upper forming surface at discharge port direction is also connected with the thickening for guaranteeing upper cutoff tool cutting edge strength Portion, in feed inlet direction without remaining wall thickness in addition to upper forming surface, there are also certain wall thickness to come in addition to upper forming surface in discharge port direction Guarantee cutting edge strength;The postive stop baffle includes two blocking material walls, and blocking material wall two sides have the upper knife body portion of upper cutoff tool to allow bit space, There are upper cutoff tool cutting edge resigning space, the length of blocking material wall and upper cutoff tool cutting edge length adaptation between two blocking material walls, steps down empty Between make cutoff tool completely into postive stop baffle with lower cutoff tool cooperate complete cutting;The lower cutoff tool includes lower tool apron Portion, positioned at the lower knife body portion cut in the middle part of portions, lower knife body portion upper surface is equipped with line sending slot, and lower knife body portion has and upper cutting The compatible two lower cutoff tool cutting edges of edge, lower cutoff tool cutting edge have lower forming surface, are equipped between two lower cutoff tool cutting edges Upper cutoff tool cutting edge resigning space;When work, the upper cutoff tool cutting edge of upper cutoff tool and the lower cutoff tool cutting edge group of lower cutoff tool At one for cutting off the complete cutting edge of copper wire to be processed, upper forming surface, lower forming surface are used to form copper wire top and bottom to be processed Chamfering, upper cutoff tool side forming surface forms copper wire the right and left chamfering to be processed;The upper I-shaped cutting edge of cutoff tool and lower cutting Element cutting is completed in edge cooperation.
The upper forming surface, lower forming surface are inclined-plane, and the shape on inclined-plane is trapezoidal.
The horizontal cross-section of the upper cutoff tool cutting edge is that class is I-shaped.
The upper forming surface of upper cutoff tool at line sending slot is shorter than the upper forming surface far from the upper cutoff tool at line sending slot.
Blocking material wall at line sending slot is longer than far from the blocking material wall at line sending slot.
Inventive die completes the cutting of armature flat copper thread elements by upper and lower cutoff tool, and discharging part is cut off by upper cutoff tool When push chip breaking from lower cutoff tool cutting edge vacate part release, complete chip breaking unloading work;Lower cutoff tool cutting edge keeps sharp side knot Structure, cutting edge is sharp when cutting, and burr big problem in section is resolved;Upper and lower cutoff tool passes through four chamfers of setting, Element makes when cutting off with chamfering at element contoured cross-section, convenient for embedding;Postive stop baffle is equipped with and upper cutting along line sending direction The blocking material wall of edge cooperation is prevented because elbow blocks up line caused by taking up element when upper cutoff tool return;Upper cutoff tool feed inlet side To, without remaining wall thickness, upper cutoff tool discharge port direction is equipped with thickening part in addition to forming chamfering, guarantee cutting edge strength, effectively enhancing knife Has service life.Upper mounting plate is equipped with spring guide pillar straight down and postive stop baffle cooperates, both for guarantee upper cutoff tool with The depth of parallelism of postive stop baffle, and the impact force of upper lower cutter when cutting off can be reduced by return spring, increase cutter life, Spring guide pillar clamping element can also be made by compressed spring, prevent armature component when cutting from loosening.The present invention has high-quality and high-efficiency High life is simple to manufacture feature low in cost, and the intensity service life greatly improves, and element is offline up to 1,200,000 or more.
