A kind of manufacturing method of the punching die of towel holder, comprises the technical steps that:
The first step:Being put into for making the towel holder of the scale of towel holder in mold, the circle of cylinder upper left is arranged on
The convex cylindrical hole exterior arc surface R angles of arc and the transverse slat on towel holder match, and transverse slat is rotated by 90 °, and riser is rotated by 90 °
Afterwards to be placed in parallel, punching is treated.
Second step:Punching machine button starts, and cope plate falls, two dresses of riser and punch forming of red needle contact towel holder
Distribution, the backward cylindrical piece of pilot hole punching and is arranged on flexible material returned washer contacts in red needle, elastic material returned washer it is anti-
Cylindrical piece is inserted in bullet effect to be arranged on outside the in vivo material-dropping hole outflow punching machine of cylinder.
3rd step:Cope plate rises, and extracts towel holder out, repeats the processing step of second step.
Advantages and advantages of the invention are as follows:
The present invention seems simple, does not know, is simply more difficult to be molded, and the original idea invented, and is exactly complicated simplification.
A kind of towel holder with die casting aluminium along strip direction it is stretched come T-shaped, be arranged on upper on T-shaped transverse slat
Dome post holes, lower dome post holes are not in one plane to assemble towel bar, and being provided with stair-stepping towel bar purpose
Be for towel ventilation it is heated after dry service, it is stretched come towel holder disposal molding, reduce work efficiency, and towel holder
The pilot hole of upper riser, by reasonable efficient processing step, another disposable punching die, punching is molded, and is both saved
Manually stablize again installation quality quick.
It is also an advantage of the present invention that:The female die embedding is uneven embedded in a cylinder left side, the end face of the right vertical arrangement of cylinder
Flat, it is for the cavity plate edge of a knife is not sharp repair to be facilitated to set that two planes of cavity plate, which do not flush,.
Cavity plate is embedded in that cylinder is left, cylinder upper right respectively, and cavity plate is porose cylinder, it is therefore an objective to punching it is big
It is small different, it only exchanges cavity plate and can be achieved with porous size requirement rather than replace entire mold.
The red needle is embedded on cope plate, and the end face of red needle does not flush, and it is for the red needle edge of a knife that the end face of red needle, which does not flush,
It is not sharp to facilitate what repair was set.
The red needle is embedded on cope plate, and red needle is cylinder, punching it is in different size, only exchanging a red needle just can be real
Existing porous size requirement rather than the entire mold of replacement.
The body structure of the present invention is simpler rationally, compared with the prior art, is simple to manufacture, easy for installation, time saving province
Power is cost-effective,
The present invention is in the structure fabrication by heavy wall die casting aluminium, has given full play to the excellent heat conductivility of die casting aluminum material, this
Towel holder is mostly connected with radiating and ventilating water heater, not only with excellent heat dissipation performance, makes towel drying effect fast, and structure letter
Single, at low cost, good appearance adapts to masses' aesthetic requirement, very popular with users through market survey, wide market.
