Abstract
Coiled sheet material is cut into strip material whose width is determined by the size of circular part. The strip is in the form of parallelogram for increasing the utilization rate of raw material by 6%.
Description
The present invention relates to a kind of programming methods of circular pieces, this technology is applicable to electricity generator stator core and the starter armature iron core of making various model automobiles, tractor, also can be used for producing other circular pieces.
At present, the electricity generator stator core technology for blanking that uses with automobile, tractor mostly is such, earlier cut into rectangular billot according to detail drawing size and technological requirement, can take single or double blanking pattern, the specifications of raw materials that China produces now is generally 1 meter, 1.25 the flat board of rice roll bending and 1 * 2 square metre, 1.25 * 2 square metres etc., they normally become the billot of 1 meter-2 meters length down, the billot length that this baiting method produces is long more, its utilization rate is high more, but its operation is also just inconvenient more, and percent defective can be high more.
Task of the present invention is that a kind of new programming methods will be provided, and it is utilized the material of circular pieces more fully, reaches economical with materials, the purpose that reduces cost.
The present invention finishes in such a way, this process is will select the roll bending material earlier, according to the circular pieces dimensional requirement becoming bibeveled billot under the material, even billot profile parallelogram, strike out disk then, be reprocessed into the chip for motor, this billot can be utilized more fully.Be described further below in conjunction with embodiment.
Embodiment: require punching out to become 0 130 disk, by traditional way is to take double blanking, its shearing is of a size of 250 * 1000, as shown in Figure 1, but the disk of 14 0 130 of this billot blankings, therefrom obviously see, the defective of this baiting method is that portion all can be not used by half waste material end to end, and the process that adopts the present invention to mention is chosen the roll bending material, according to the requirement of processing parts becoming bibeveled billot under the material, as shown in Figure 2.Like this, unavailable half waste material of portion just in time gathered and became a finished product end to end originally, according to measuring and calculating, with the same volume of timber, adopted this process blanking, and its utilization rate for the semiprocessed materials accumulative total can improve more than 6%.
Claims (1)
1, a kind of technology for blanking of circular pieces is characterized in that: choose the material of roll bending material, according to becoming bibeveled billot under the circular pieces dimensional requirement, make this billot profile parallelogram, strike out disk then, be reprocessed into desired part.
