Abstract
The utility model provides an end-milling cutter capable of regenerating and reusing for cutting printed circuit board, which is mainly formed by connecting a carbonization tungsten material blade part to a stainless steel handle. The blade is made through cutting and grinding pole of a recycled printed circuit board end-milling cutter, to form the cutting blade with smaller diameter at the front end. The back end has a tapered head with bigger diameter, while the handle has the characteristic that the blade back part has the most connecting area, connecting one end surface of the handle with the end surface of the head so as to provide the best welding intensity. Finished blade and handle can be used for making the eccentric grinding and processing, and the welding material at the welding place is simultaneously eliminated, the cutter formed by the method can have the eccentric cutting precision and can reduce the manufacture cost.
Description
Technical field
The utility model relates to the printed circuit board (PCB) end mill(ing) cutter of a kind of milling cutter, particularly a kind of reproducible utilization.
Background technology
Traditional printed circuit board (PCB) end mill(ing) cutter is made by the tungsten carbide material of high rigidity, cause the wearing and tearing or the fracture at blade position after implementing the cutting bore operation on the printed circuit board base board, generally speaking the printed circuit board (PCB) end mill(ing) cutter drill bit of this blade position breakage is just treated as scrap with it.Yet, tungsten carbide raw material production capacity shortage gradually at present, cause raw material acquisition cost moment with regard to more than the surging numerical digit, for for the industry of producing the printed circuit board (PCB) end mill(ing) cutter, because tungsten carbide material cost costliness, cause manufacturing cost to reduce, cause economic benefit to reduce, this is the problem that industry faced of producing the printed circuit board (PCB) end mill(ing) cutter at present.
Summary of the invention
The purpose of this utility model provides a kind of printed circuit board (PCB) end mill(ing) cutter that can regeneration.
The utility model is to realize like this, a kind of printed circuit board (PCB) end mill(ing) cutter of reproducible utilization, it is characterized in that: this printed circuit board (PCB) end mill(ing) cutter docks the binding shaping mutually by the blade part of a tungsten carbide material and the handle of a knife portion of a stainless steel, this blade part is that the bar portion that will reclaim printed circuit board (PCB) end mill(ing) cutter scrap cuts off attrition process again and makes, has cutting blade to form front end than minor diameter, the rear end has a neck than major diameter and tapered kenel, and handle of a knife portion utilizes blade part rear end neck to have the maximum characteristic that connects area, one end and this neck finish butt welding fixed bit are linked into an integrated entity, be provided with having best weld strength, can impose concentric attrition process by the blade part and the handle of a knife portion of this shaping, and this butt joint welding place evagination is removed simultaneously in the scolder at edge.
Therefore the utility model has the advantages that to have preferred rotary stability when processing and implementation, the unlikely cutting accuracy that influences causes the printed circuit board base board that cuts out to conform with required precision, and then can reach the manufacturing cost that reduces production printed circuit board (PCB) end mill(ing) cutter.
Describe specific embodiment of the utility model in detail below in conjunction with accompanying drawing, so that make technological means of the present utility model, feature and advantage become clearer.
Description of drawings
Fig. 1 is a three-dimensional appearance schematic diagram of the present utility model.
Fig. 2 is the decomposing schematic representation of the utility model associated components.
Fig. 3 is the generalized section after the utility model associated components butt joint solid welding.
Drawing reference numeral explanation: blade part 1; Cutting blade 11; Neck 12; Handle of a knife portion 2; Butt joint weld 3; Scolder 4.
Embodiment
Referring to Fig. 1 to Fig. 3, the utility model provides the printed circuit board (PCB) end mill(ing) cutter of tool reproducible utilization mainly to dock the binding shaping mutually by the blade part 1 of a tungsten carbide material and the handle of a knife portion 2 of a stainless steel.The bar portion that this blade part 1 will reclaim printed circuit board (PCB) end mill(ing) cutter scrap cuts off attrition process again and makes, has cutting blade 11 to form front end than minor diameter, the rear end has a neck 12 than major diameter and tapered kenel, and the handle of a knife portion 2 of stainless steel utilizes blade part 1 rear end neck 12 to have the maximum characteristic that connects area, one end and this neck 12 end face butt welding fixed bits are linked into an integrated entity, so butt joint solid welding mode has best weld strength, and 3 evaginations of this butt joint weld are in the scolder 4 at edge, can by the blade part 1 of this shaping and handle of a knife portion 2 imposes concentric attrition process and remove simultaneously, and then reach blade part 1 and the concentric precision of handle of a knife portion 2 both tools, therefore in processing and implementation, have preferred rotary stability, the unlikely cutting accuracy that influences, cause the printed circuit board base board that cuts out to conform with required precision, the printed circuit board (PCB) end mill(ing) cutter outward appearance of the reproducible utilization of formed thereby has preferable aesthetic property relatively.
In sum, this creation provides the printed circuit board (PCB) end mill(ing) cutter structure of tool reproducible utilization, implement in the running in integral cutting, not only has the good clamping locate mode of stability, also can reach the required precision of new product cutter ad eundem, can solve simultaneously the problem that present institute faces the manufacturing cost increase, be minimized manufacturing cost, can meet the practical value and the purpose of expection.
