Share hardware stamping die shut height design standard
Today, the author of this article to share is how to design the hardware stamping mold reasonable height.
First of all, the authors take you learn about the stamping die reasonable height is what?
Metal stamping die shut height refers to the mould at the lowest position, on the template on plane and the distance between the plane under the template.
When we were falling in the slider, will not be able to direct the punch height set to die shut height, but should be greater than the height of the mould.
Although now most punch are automatically determine the function of the height, but one thing is we have to remember: metal stamping mold material, this time we got by measuring the mould height, this is the mould height.
During the process of production of metal stamping parts, if the press directly to the height is set to the height of mould, due to the large pressure, punch performance will reduce can directly open or closed the fuselage.
Some old equipment used for a long time, can appear even stuck.
Too much closing force can make round indentation on the mold base.
Limit column in the trace on the mold base, so that you can use them to check mold high?
Limit column can be used to check the mould height, of course, not only this kind of usage, adjust the height of the mould, measure the parallelism of the slider can be made of round to.
We are in the first frame mode, let column spacing between 0.
5 mm clearance, after the aircraft model to adjust the mould height to the height of the actual needs, this also can yet be regarded as a kind of good way.
Here, also said the die height correction: general metal stamping mold there will be two to four column spacing, the positive grinding limit column is about 0.
7 mm to 1.
0 mm in the same groove.
With a material or lead, placed in the slots start punching machine, if there isn't a crush limit column, can lead the line thickness measurement.
Many limit column after punch closed the gap to general is 0.
5 mm, if the lead wire after flattening of 1.
7 mm, groove depth of 1.
3 mm, so can reduce the 0 again.
38 mm to keep column spacing between 0.
02 mm clearance.
