Abstract
The utility model relates to a three-phase asynchronous motor stator punching sheet shearing cutter which is composed of an upper cutter and a lower cutter. The three-phase asynchronous motor stator punching sheet shearing cutter is characterized in that: the upper cutter is a camber line shaped upper cutter, and the lower cutter is a camber line shaped lower cutter; the lower edge of the camber line shaped upper cutter is provided with a camber line shaped upper cutting blade, and the upper edge of the camber line shaped lower cutter is provided with a camber line shaped lower cutting blade which matches the camber line shaped upper cutting blade. The three-phase asynchronous motor stator punching sheet shearing cutter is scientific and reasonable in structural design. The camber line shaped cutter is adopted to directly cut a raw material into material sheets whose two sides are curvilinear shaped. There is no wasted space between the material sheets so that utilization rate of the raw material is greatly enhanced, and thus the three-phase asynchronous motor stator punching sheet shearing cutter is one with relatively high innovativeness.
Description
Technical field
The utility model relates to field of motor manufacturing, particularly a kind of threephase asynchronous stator punching shearing tool.
Background technology
The raw-material shearing of existing threephase asynchronous stator punching, complete by two procedures, at first raw material is cut into to the straight flitch of one fixed width according to stator diameter, then on this straight flitch, adopt blanking units to cut out the annular stator punching.Wherein, the first operation adopts the linear pattern cutter to carry out the shearing of raw material silicon steel sheet more, this processing mode, and after straight flitch cuts out the annular stator punching, surrounding has produced large-area expense material, therefore causes the significant wastage of raw material.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of threephase asynchronous stator punching shearing tool of effective conservation is provided.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of threephase asynchronous stator punching shearing tool, by upper cutter and lower cutter, formed, it is characterized in that: described upper cutter is the arc line shaped upper cutter, described lower cutter is the arc line shaped lower cutter, under described arc line shaped upper cutter, along being shaped with the arc line shaped upper knife edge, on described arc line shaped lower cutter, edge is shaped with blade under the arc line shaped matched with described arc line shaped upper knife edge.
And, all make spaced installing hole on the cutter hub of described arc line shaped upper cutter and arc line shaped lower cutter.
And under described arc line shaped upper knife edge and arc line shaped, blade forms by a plurality of isometrical concave arc sections that are arranged alternately and dome segmental arc.
Advantage of the present utility model and beneficial effect are:
1. this threephase asynchronous stator punching shearing tool, make original linear pattern cutter into the arc line type cutter, and the diameter of cutter camber line depends on the diameter of stator punching, in addition, and need to be in the shearing scrap (bridge) surplus of the reserved 5～6mm of diametric(al); On cutter, the design of installing hole is the perpendicularity of cutter while guaranteeing shearing and the gap between upper bottom tool, thereby controls the burr of tablet.
2. this threephase asynchronous stator punching shearing tool, take diameter as φ 260 stator punching shearing tools be example, on the curve cutter, the diameter of circular arc is φ 265mm, when raw material are the width silicon steel sheet that is 1200mm thickness 0.5mm, by 4.5 tons of every volumes, through calculating, use the utilization rate of raw materials of the cutter shearing tablet of this programme greatly to improve, compared to the linear pattern cutter, can save 14.3% material, obtained good economic benefit.
3. the utility model scientific structure design is reasonable, adopt the arc line shaped cutter, it is curved tablet that raw material are directly cut into to both sides, after flitch cuts out the annular stator punching, the charge level that takes that surrounding produces amasss significantly minimizing, significantly having improved raw-material utilance, is a kind of motor stator punching shearing tool with higher innovation.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is shearing tool operation principle schematic diagram of the present utility model.
The accompanying drawing explanation:
Under 1-arc line shaped upper cutter, 2-arc line shaped upper knife edge, 3-installing hole, 4-arc line shaped lower cutter, 5-arc line shaped, blade, 6-installing hole, 7-both sides are that corrugated tablet, 8-cut off track, 9-raw material.
Embodiment
Below by specific embodiment, the utility model is described in further detail, and following examples are descriptive, is not determinate, can not limit protection range of the present utility model with this.
A kind of threephase asynchronous stator punching shearing tool, by upper cutter and lower cutter, formed, its innovation is: described upper cutter is arc line shaped upper cutter 1, described lower cutter is arc line shaped lower cutter 4, under described arc line shaped upper cutter, along being shaped with arc line shaped upper knife edge 2, on described arc line shaped lower cutter, edge is shaped with blade 5 under the arc line shaped matched with described arc line shaped upper knife edge.
All make spaced installing hole 3,6 on the cutter hub of arc line shaped upper cutter and arc line shaped lower cutter.
Under arc line shaped upper knife edge and arc line shaped, blade forms by a plurality of isometrical concave arc sections that are arranged alternately and dome segmental arc.
Operation principle of the present utility model is:
By arc line shaped upper cutter of the present utility model and arc line shaped lower cutter all with 60 angle, be fixedly mounted on respectively on the upper cutter head and lower tool rest of cutting machine, raw material 9 are delivered to cutting machine, the angle that now the cut-out track 8 of cutting knife and raw material edge are the a=30 degree.After cut-out, forming both sides is corrugated tablet 7.
Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: in the spirit and scope that do not break away from the utility model and claims, various replacements, variation and modification are all possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
