Description
Technical field
The utility model relates to the stamping die that scaffold board is carried out punching.
Background technology
At present, national economy and scientific and technical develop rapidly, building trade is that the update of construction apparatus is also rapid unusually, wherein just comprises scaffold in advance.
Scaffold generally includes several support units, is erected with scaffold board on each support unit, and the workmen can be in this scaffold board walking, convenient construction operation.Therefore, the intensity of scaffold board and workmen's safety is closely related.In order to strengthen the intensity of scaffold board, usually need be on scaffold board the some structure hole of moulding.Prior art is to utilize the disposable punching molding of pressing equipment when the described structure hole of moulding, namely blank is stretched, and the blank after stretching is carried out punching, and the action that stretches is continuous with the punching action.This can cause a large amount of burr, the cracks of marginal existence of described structure hole, and the existence in burr, crack will make scaffold board easy deformation, fracture, thereby jeopardizes workmen's personal safety.And, owing to need the described structure hole of disposable punching molding, answer the power requirement of this pressing equipment higher.In addition, the described structure hole of disposable punching molding, the scaffold board discontinuity makes whole scaffold board to be twisted by powerful internal stress.
The utility model content
The utility model provides a kind of stamping die that scaffold board is carried out punching, and it has overcome the existing deficiency of background technology.The technical scheme that its technical problem that solves the utility model adopts is:
A kind of stamping die that scaffold board is carried out punching, it comprises patrix, counterdie and die sleeve, this patrix comprises press section and thrusts portion, this upper end of thrusting portion is connected with the lower end of this press section, this edge that thrusts the lower end of portion forms stamping knife, the width of the upper end of this press section is greater than the width of its lower end, the middle part of this counterdie is provided with material-dropping hole, the top edge of this material-dropping hole forms down stamping knife, this time stamping knife cooperates with this last stamping knife goes out through hole with scaffold board, vertically run through being provided with perforation on this die sleeve, this counterdie is housed in this perforation, and this die sleeve cooperates the edge with this through hole to stretch with this press section.
Among one preferred embodiment: this patrix can vertically move back and forth, and this die sleeve can vertically move back and forth.
Among one preferred embodiment: the cross sectional shape of this press section is trapezoidal.
Among one preferred embodiment: the outer surface of this press section and this thrust angle between the portion≤160 degree, 〉=120 degree.
Among one preferred embodiment: the outer surface of this press section and this thrust angle between the portion≤150 degree, 〉=130 degree.
The technical program is compared with background technology, and it has following advantage:
1. this is gone up stamping knife and with first cooperation of this time stamping knife scaffold board is gone out through hole, then, this die sleeve cooperates the edge with this through hole to stretch again with this press section, the interaction force between described upper die and lower die, the die sleeve is less, and low power pressing equipment can be realized producing.
In addition, go out described through hole on the scaffold board after, it is smooth that scaffold board still keeps, when again the edge of through hole being stretched, scaffold board stressed evenly, can not have too big internal stress, so the scaffold board flatness is better.
2. go out through hole earlier, the edge to through hole stretches again, makes the edge of this through hole smooth, neat, does not have burr, crack, makes the service life of scaffold board longer.
3. during die-cut this through hole, this counterdie maintains static, and this patrix is mobile straight down; When stretching the edge of this through hole, this patrix maintains static, and this die sleeve is mobile straight up.Because this patrix is just in time opposite with the direction of motion of this die sleeve, so the internal stress that the internal stress that die-cut through hole produces produces can be with the stretching through hole time offsets, avoid having stress greatly in the scaffold board, guarantee that scaffold board has flatness preferably.
In addition, when stretching, this die sleeve drives blank integral body and moves up, and blank is attached on this die sleeve all the time, and flatness is better.
4. because the flatness of scaffold board is better, needn't not outer scaffold board be fixed during installation, install very convenient.
