Description
Technical field
This utility model relates to a kind of for foil and the puncher of plastic sheeting, particularly relates to a kind of existing
In the case of punching requires very high degree of precision, change traditional direction, improve precision, not by the shadow of fever expansion
Ring, wear and tear little, effectively reduce the accurate puncher of processing cost.
Background technology
In Flexible-Packaging Industry is processed, it usually needs plastic sheeting is punched out, such as Washing powder packaging bag,
The Plastic bag used during market shopping, it is simply that the Liang Ge ear in Plastic bag carries out punching, and so may be used
To be convenient for people to mention weight.It addition, in metal-working industry, it is also desirable to foil is punched out,
Such as, at this lithium battery row high to the requirement of contoured edge burr of punching film-making to Copper Foil, aluminium foil etc.
Industry.
The mode punching plastic sheeting and foil usually uses puncher, existing puncher
Structure include top base, drift, lower mold and cylinder, top base offers the sliding eye coordinated with drift,
Lower mold offers the punching hole coordinated with drift, plastic sheeting or foil and is arranged between drift and lower mold,
When punching, the outfan of cylinder promotes drift slide downward in the sliding eye of top base, makes drift enter
The sliding eye of lower mold so that plastic sheeting or and foil stamp out rush identical with punch shape of shape
Hole.
Due to plastic sheeting and and foil self character, the drift needs of the most above-mentioned puncher
Plastic sheeting could be got, with the punching hole precision-fit of the sliding eye of top base and lower mold, the hole that quality is higher
Hole, both fit clearances need to be accurate to μ rank sometimes；But, this high-precision leakproof fit puncher
Extremely being easily subject to external environment impact, the most influenced by ambient temperature, part expands with heat and contract with cold and precision can be made to send out
Raw change, when temperature is higher, drift, top base and lower mold fever expansion so that drift is very easily upper
In the sliding eye of pedestal and the punching hole of lower mold stuck, cause puncher not run, even if can run reluctantly,
Owing to friction is relatively big, the most easily abrasion drift and hole wall, thus cause frequently changing drift, improve
Production cost；It addition, this high-accuracy cooperation is also required to carry out corresponding high-accuracy processing, this makes punching
The difficulty of processing of machine increases.
