Description
Technical field
The utility model relates to ring-type cutting tool field, relates in particular to a kind of unsteady adding pressure type ring-type cutting dedicated tool of processing slim sheet material.
Background technology
Along with progress and the development of industrial technology, the slim sheet materials such as aluminium alloy, plastic plate, stainless steel are widely used.When this type of slim sheet material was opened the circular hole of made large-diameter or produced large diameter circular sheet material, if punch die processing or manual cutting out by opening different-diameter processed, cost or expenditure of time were huge.When small lot batch manufacture, the cost defective of punch die processing technology is just more obvious.
And utilize cutter to carry out the ring-type cutting at plain-milling machine, the technique that makes slim sheet material finish perforate or feeding along inside and outside two parts separation of cutter rotational trajectory has more cost-effectivenes.But adding man-hour, because sheet material very thin (only having approximately 0.8mm~1mm thickness), because having enough rigidity, sheet material itself do not bear the main cutting force that acts on its vertical direction, process along with the cutter of making the ring-type cutting movement, sheet material shows as makes the regular trace movement of being depressed by cutter with resilience, can not keep smooth in working angles; On the other hand, because the circumferential moment of torsion in major diameter cutter when work is larger, the circumferential moment of torsion when requiring have larger clamping to make every effort to overcome and taking cutter work.Therefore, the clamping measure must guarantee the planarization of sheet material work in-process and have enough clamping power.
Existing ring-type cutting dedicated tool, comprise rotation cutter hub, the cutter head that is arranged on the Telescopic knife bar on the described rotation cutter hub and is arranged on described Telescopic knife bar end, by the flexible radius of regulating the cutting of cutter head ring-type that cooperates between rotation cutter hub and the Telescopic knife bar, rotarily drive the cutting of cutter head ring-type by the rotation cutter hub.In order to improve the planarization of sheet material processing, the utility model imagination can be carried out ring-type to sheet material and exert pressure, thereby guarantee the planarization in the ring-type cutting belt zone of sheet material in working angles before the cutting of cutter head ring-type and in the cutting process, and have the power that overcomes of enough circumferential moments of torsion, make stable cutting.
Existing adopt pressing plate to be pressed on the sheet material to exert pressure mode such as manual type of sheet material, the location of pressing plate, clamping and exert pressure, no matter be in the inside in ring-type cutting belt zone or the enforcement of external margin, all exist the accuracy of location be difficult for to hold and the problems such as very complicated are compared in the clamping operation, thereby cause long processing time, operating personnel's labour intensity large, work efficiency is low.Use the cutter of this ring-type cutting obviously can not satisfy the requirement of the aspects such as in enormous quantities, high-quality in the real work, high efficiency.
The utility model content
The utility model provides a kind of unsteady adding pressure type ring-type cutting dedicated tool, when milling machine is processed slim sheet material major diameter round hole or is produced circular sheet material, the ring-type pressing plate is concentric, synchronous with the rotation cutter hub, make clamping simple and quick, and can guarantee the planarization of slim sheet material work in-process and have enough clamping power.
A kind of unsteady adding pressure type ring-type cutting dedicated tool, comprise rotation cutter hub, the cutter head that is arranged on the Telescopic knife bar on the described rotation cutter hub and is arranged on described Telescopic knife bar end, the bottom of described rotation cutter hub is provided with the ring-type pressing plate that is slidingly matched with described rotation cutter hub.
