Description
Technical field
The present invention relates to a kind of for foil and the puncher of plastic sheeting, particularly relate to a kind of in the case of punching requirement very high degree of precision, change traditional direction, improve precision, do not affected by fever expansion, 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 can be convenient for people to mention weight.It addition, in metal-working industry, it is also desirable to foil is punched out, such as, in this lithium battery industry high to the requirement of contoured edge burr of punching film-making to Copper Foil, aluminium foil etc..
The mode punching plastic sheeting and foil usually uses puncher, the structure of existing puncher includes 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 are arranged between drift and lower mold, when punching, the outfan of cylinder promotes drift slide downward in the sliding eye of top base, make drift enter lower mold sliding eye so that plastic sheeting or and foil stamp out the punching that shape is identical with punch shape.
Due to plastic sheeting and and the reason of foil self character, the drift of the most above-mentioned puncher needs the punching hole precision-fit of the sliding eye with top base and lower mold that plastic sheeting could be got the hole that quality is higher, and both fit clearances need to be accurate to μ rank sometimes；But, this high-precision leakproof fit puncher is extremely 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 change, when temperature is higher, drift, top base and lower mold fever expansion so that drift is very easily stuck in the sliding eye of top base and the punching hole of lower mold, puncher is caused 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 the difficulty of processing of puncher increase.
Summary of the invention
It is an object of the invention to provide a kind of in the case of high-accuracy cooperation, do not affected by fever expansion, wear and tear little, effectively reduce the accurate puncher of processing cost.

Compared with prior art, the present invention is by arranging described roller guiding mechanism, utilize the support on described roller guiding mechanism, described roller is made to be placed between outfan and the described sliding eye of described cylinder, so that in Structure deformation between the lateral wall of the outfan of described cylinder and roller and between the hole wall of described sliding eye and described roller, so on the one hand, avoid punch die directly directly to contact with sliding eye, and then make punch die, top base and lower mold are not affected by fever expansion, ensure that punch die will not be stuck, and avoid and wear and tear between punch die and sliding eye, the hole wall of the most described sliding eye is without processing high-precision plane, effectively reduce difficulty of processing, and reduction processing cost.
It is preferred that have the fixed block of fixing connection on the outfan of described cylinder, described fixed block is connected with described punch die, contacts at the lateral wall of fixed block described roller rolls.
It is preferred that described top base has connecting frame, described connecting frame is offered described sliding eye.
It is preferred that each side of described support is equipped with described roller, described roller is needle roller, and the drive-connecting shaft of described needle roller is perpendicular to the central shaft of the outfan of described cylinder.
Specifically, each side opening of described support is provided with some grooves, and described needle roller is arranged in described groove.
More specifically, two relative sidewalls of described groove are arc-shaped, described needle roller is embedded in described groove, so that the both sides of described needle roller are projected into the two sides of described support.
More specifically, described groove is along the central axis direction arrangement of the outfan of described cylinder.
It is preferred that described accurate puncher also includes that bottom base, described lower mold are fixed on described bottom base.
