Description

A kind of cold punching doffer

Technical field

The utility model relates to LED lamp production and processing technical field, specifically a kind of cold punching doffer.

Background technology

LED lamp outer shell adopts aluminum material to make mostly, aborning, need to use blanking apparatus, existing cold punching blanking die, by upper, bed die cooperation is assembled, due to mould processing technology and structure, and blanking workpiece material, the impact of thickness etc., the cutting edge position of upper and lower mould can be made to have certain roughness, its surface is made to produce certain groove, simultaneously because aluminium has certain ductility, particularly film aluminum product, itself intensity difference in the process of stamping and blanking, also certain deformation can be produced, section can produce some burrs, be filled in the groove of die point position, form blocking, if continuous stamping, burr can fill up the reserved gap of upper and lower mould, accelerate the friction of upper and lower mould, heat-dissipating, expand thus meeting distending counterdie, mould is caused to be scrapped.And the roughness reducing upper and lower mould cutting edge can increase manufacturing cost greatly, and adopt the method for labor cleaning's burr, need to shut down process, which decrease production efficiency, do not shut down the security risk that process strengthens again.

Utility model content

For solving the problem, the utility model discloses a kind of cold punching doffer, comprise: slider of punch, mold, bed die, workbench, air compressor, through swtich, connecting rod, described mold is fixed on slider of punch, described bed die is on the table affixed, bed die and mold match, and the blanking port of bed die and outside have two passages, described air compressor is connected with the passage on bed die by tracheae, described through swtich is on the table affixed, through swtich is arranged on the tracheae that air compressor is connected with bed die, described connecting rod is fixed on slider of punch, be positioned at above through swtich.

The utility model is a kind of cold punching doffer, by improveing traditional mould, two passages are outputed in bed die inside, and connect air compressor to passage, the switch of tracheae is set simultaneously on the table, when stamping-out, through swtich pushed down by connecting rod on slider of punch, tracheae is connected, air is blown into mould by air compressor, not only can be blown away instantaneously by powerful air-flow by the burr produced in blanking process, compressed air also can play cooling effect to upper/lower die cutting edge simultaneously, thus substantially prolongs the mold use life-span.

The utility model has the advantages such as structure is simple, safe and practical.
