Abstract
Splice preforming honeycomb numerical-control processing method the present invention relates to a kind of cladding, clamping positioning method in the process is novel and with novelty, cutting parameter and technological process are reliable by verification experimental verification, solve the digital control processing that cladding splices preforming honeycomb parts.
Description
Technical field
Splice preforming honeycomb numerical control processing technology the invention belongs to cladding in composite material sandwich structure part, be related to one
The NC milling process of the individual honeycomb pellet suitable for same or similar mixing material.
Background technology
Clamping both at home and abroad for simple paper Honeycomb Products: Their, cutting tend to be ripe, and develop numerous dedicated tool and
Equipment, with the deep application of composite material structural member aboard, the extension of structure type and application is occurred in that by many
The honeycomb core structures that the mixing of kind of material is spliced, the manufacturing technology foreign countries of this class formation have been carried out technical research for many years and
Using, and the technical scheme and specification of maturation, but state have been formulated for similar and other different types of sandwich structures respectively
Interior process program and flow to such sandwich structure temporarily without more maturation.
The content of the invention
The purpose of invention
The purpose of the present invention is to propose to simple, the high in machining efficiency cladding splicing of a kind of frock less investment, technological process is pre-
Formed honeycomb numerical control processing technology method, to overcome multiple material to mix the discontinuity of materials for the honeycomb core being spliced, is protected
Passing rate of processing is demonstrate,proved, typical cladding splices preforming honeycomb such as Fig. 1.
Except structure shown in Fig. 1, its upper and lower surface glued membrane, fiber cloth or peelable cloth can also be increased again, can be in upper and lower surface
Closing smooth surface is formed, and easily departs from preforming frock.
The technical scheme of invention
A kind of cladding is provided and splices preforming honeycomb numerical-control processing method, this method is high using Five Axis in closing space
Fast processing center machine tool and honeycomb numerical control machining cutter, described cutter is the crushing type combination shaping honeybee of Hardmetal materials
Nest milling cutter, the processing method comprises the following steps：
Step 1: cladding is spliced into preforming honeycomb pellet is processed as pellet edge wheel relative to wide protrusion 2 in the middle of pellet
Times thickness；
Step 2: opening positioning hole on the most long-diagonal two ends of honeycomb pellet；The aperture of one of positioning hole and machine
Bed alignment pin is adapted, and the aperture of another positioning hole is 2 times of lathe alignment pin diameter；
Step 3: in the bottom surface of honeycomb pellet and positioned at the fiber cloth of position of positioning hole 3 millimeters thicks of setting, being used as reinforcement
Layer；
Consolidated Step 4: by Flexible Clamp System and lathe alignment pin preforming honeycomb pellet will be spliced by cladding
It is fixed；Wherein by the sucker suction of Flexible Clamp System on the smooth surface of the fiber cloth of the bottom surface of honeycomb pellet；
Step 5: being protected to the non-cutting region of honeycomb pellet using plastic foil；
Step 6, roughing is carried out by the crushing type combination shaping honeycomb milling cutter of major diameter, and processing mode is ladder point
Layer form, tool base is with path in 5 to 10 ° of angles；
Step 7: being finished using the crushing type combination shaping honeycomb milling cutter of minor diameter, processing mode is using profile-followed
Processing side
Formula is carried out, and tool base is with product face in 3 to 5 ° of angles.
Beneficial effect
● it can at a high speed, with the shape process, reduce cutting stress；
● prevent the diffusion of chips (dust).
The use of customization frock is reduced using Flexible Clamp System, fund input is reduced, is completed with digitlization means
The face moulding of frock type.
The formulation of machined parameters and Processing Strategies, has used for reference the strategy of metal material cutting, parameter is according to tactful different works
Condition is selected, it is ensured that cutting quality and precision, and processing efficiency is improved again.
Brief description of the drawings
