Abstract
It is that lower die cut side body and material control device be installed on lower mold in original diel the present invention relates to a kind of aluminium sheet cutting-off controlling method of diel, lower die cut side body and material control device are mutually met with the part of diel；Aluminium sheet cutting-off controlling method is, when mold body is descending, pressure rings first contact lower die cut side body, pressure rings play binder effect, when continuing traveling downwardly, in the increased material control device of lower mould, while upper cross cutting side body contacts plate, the material control device of lower mould plays retainer by plate with upper cross cutting side body and acted on, now by providing binder effect between pressure rings and lower die cut side body on the inside of part, waste material is by forming retainer effect on the outside of part between lower mould material control device and upper cross cutting side body, when continuing traveling downwardly, upper cross cutting body in body and lower die cut completes trimming process, can therefore it be compressed with mould material control device at present, play binder trimming action, ensure part stability, reduce the generation of chip and burr.
Description
Technical field
The present invention relates to a kind of method of aluminium sheet cutting-off controlling chip for diel and lifting cross section quality, and in particular to
The material control device cut off by aluminium sheet is come the method that reduces chip.
Background technology
In the processing and fabricating field of aluminium sheet, because aluminium sheet is softer, material is readily flowed.Traditional uncontrollable waste material of aluminium sheet trimming
Stay or waste material flow tendency, so that the generation of the cross section quality and chip of uncontrollable part edge.
As shown in Fig. 2 in traditional aluminium sheet cut-out during cross cutting side body contact plate, upper cross cutting body in body and lower die cut starts
Work, when continuing traveling downwardly, upper cross cutting is in body and body will complete trimming action during lower die cut, now waste material side due to aluminium sheet it is softer,
Material easily flows, the generation of the cross section quality and chip of uncontrollable part edge during trimming.Therefore, how to be controlled in trimming
The generation of the cross section quality and chip of part edge becomes the technical problem for being badly in need of solving.
The content of the invention
The invention aims to solve to control the cross section quality of part edge and the technology of chip in diel trimming
Problem, the present invention increases material control device in original diel at the lower die cut side of aluminium sheet trimming, reduces the stream of tablet
It is dynamic, reduce burr and chip that trimming is brought to part edge so as to reach.That is, soft body retainer is increased below trimming waste material
Material flowing and waste material flow tendency can be controlled, it is ensured that waste material is cut off under not mobility status, so as to reduce burr and chip.
The present invention concrete technical scheme be：A kind of aluminium sheet cutting-off controlling method of diel, includes original
The mold body of diel, lower mold, pressure rings, upper cross cutting body, nitrogen spring and spacing dress in body, lower die cut
Put；Cross cutting side body is installed on the mold body；The centre of pressure rings and mold body is provided with nitrogen spring and spacing
Device；Nitrogen spring is the pressure source of back and forth movement between mold body and pressure rings；Stopping means is used for mold body and pressure
The position-limiting action of power interannular；
Its feature is that lower die cut side body and material control device are provided with lower mold, and lower die cut side body is with material control device
Mutually meet with the part of diel；
When mold body is descending, pressure rings first contact lower die cut side body, and pressure rings play binder effect, when continuing traveling downwardly,
Lower mould increases material control device, and while upper cross cutting side body contacts plate, material control device and the upper cross cutting side body of lower mould pass through plate
Part plays retainer effect, now by providing waste material on the outside of binder effect, part between pressure rings and lower die cut side body on the inside of part
By forming retainer effect between lower mould material control device and upper cross cutting side body, when continuing traveling downwardly, upper cross cutting body when body is with lower die cut is complete
It into trimming process, can therefore be compressed with mould material control device at present, play binder trimming action, it is ensured that part stability, reduce broken
The generation of bits and burr.
Further, the material control device endurance is more than 10% or so of trimming pressure-plate-force.
The inventive method is easy to make, and process is simple, has a good application prospect.
Brief description of the drawings
Fig. 1 is a kind of aluminium sheet cutting-off controlling method schematic diagram of diel of the invention；
The aluminium sheet cut-out schematic diagram of Fig. 2 prior arts.
The aluminium sheet cut-out schematic diagram of the increase material control device of Fig. 3 present invention.
In figure：1. cross cutting body 6. in 5. lower die cut of body is controlled in the pressure rings 4. of 2. times molds of mold body 3.
Expect the waste material of 7. nitrogen spring of device, 8. stopping means 9..
Embodiment
The principle that the invention will now be described in detail with reference to the accompanying drawings, for clearly illustrating technical scheme.
Fig. 1 is the working state figure that the present invention carries out punching press to part；
A kind of aluminium sheet cutting-off controlling method of diel, includes the mold body 1 of original diel, lower mold
2nd, pressure rings 3, upper cross cutting body 5, nitrogen spring 7 and stopping means 8 in body 4, lower die cut；It is provided with the mold body
Upper cross cutting side body；The centre of pressure rings and mold body is provided with nitrogen spring and stopping means；Nitrogen spring is mold body
The pressure source of back and forth movement between pressure rings；Stopping means is used for the position-limiting action of mold body and pressure interannular；
Its feature is that lower die cut side body and material control device are provided with lower mold, and lower die cut side body is with material control device
Mutually meet with the part of diel；
As shown in figure 3, mold body 1 first contacts lower die cut side body 5 during pushing by pressure rings 3, binder effect is played,
Strengthen the stability of part.Mold body 1 is continued traveling downwardly when upper cross cutting side body 4 is contacted with part and lower mould material control device 6,
Part, which is in, starts trimming state, and now material control device 6 plays binder effect.The material control device endurance is more than trimming binder
10% or so of power.The material control device of lower mould plays retainer by plate with upper cross cutting side body and acted on, now by pressure on the inside of part
There is provided binder between ring and lower die cut side body to act on, waste material 9 between lower mould material control device and upper cross cutting side body by forming on the outside of part
Retainer is acted on, and when continuing traveling downwardly, when continuing traveling downwardly to terminal with mold body, upper cross cutting body 5 when body 4 is with lower die cut is completed
Therefore trimming, can compress with mould material control device at present, play binder trimming action, it is ensured that part stability, reduce chip and hair
The generation of thorn.
