Abstract
The invention relates to milling of a special workpiece and further relates to an aluminum material cooling shell machining method. The aluminum material cooling shell machining method is resistant to deformation. The aluminum material cooling shell machining method comprises the process that the side faces, an inner cavity and a cavity bottom of a cuboid aluminum material are roughly machined, and the side faces, the bottom face and cooling grooves of the cuboid aluminum material are roughly machined; aging treatment is performed; and finish machining is performed on the inner cavity, holes in the side walls and corresponding threads in the holes, finish machining is performed on the cooling grooves at the two ends, finish machining is performed on the cooling groove which is located in the middle and not subjected to finish machining, and finish machining is performed on the side walls. The aluminum material cooling shell machining method has the beneficial effect that due to rough machining, aging treatment and finish machining, deformation of the workpiece is eliminated.
Description
Technical field:
The present invention relates to a kind of milling of special workpiece, relate to aluminium radiating shell processing method further.
Background technology:
As Figure 1-3, aluminium radiating shell is by the aluminium of entirety, and milling forms step by step, and overall connection does not have seam, and intensity is large, and good seal performance, thermal diffusivity is strong.Radiating shell comprises internal cavities and outside heat sink, overall dimensions: 314*165*60 millimeter, radiating groove sidewall, i.e. radiating ribs, thickness 5 millimeters, and local thickness 2 millimeters belongs to typical thin wall housing; And as shown in Figure 10, root does not have fillet, so whole workpiece easily produces flexural deformation in radiator process.Traditional processing method: on machining center, milling forms; But the distortion that traditional processing method can bring workpiece serious.Need improvement badly.
Inventive method:
The object of the invention is: the aluminium radiating shell processing method providing a kind of resistance to deformation.Aluminium radiating shell processing method, lathe is three shaft vertical machining centers, and process comprises:
Operation one: at the bottom of the side of roughing cuboid aluminium, inner chamber and chamber, profile allowance 2 millimeters, allowance 2 millimeters at the bottom of inner chamber and inner chamber;
Operation two: the side of roughing cuboid aluminium, bottom surface, radiating groove, radiating groove sidewall thickness allowance 1 millimeter, other thickness allowance 2 millimeters;
Operation three: Ageing Treatment: adopt room temperature natrual ageing 2 hours, then 195-205 degree Celsius of artificial aging 2 hours;
Operation four: fine finishining inner chamber, be positioned at screw thread corresponding to hole on sidewall and hole, adopts little cutting-in, roughing feed technique, reduces heat in metal cutting, and then reduce distortion;
Operation five: use inner chamber location-plate as fixture, mid portion radiating groove pushed down by pressing plate, fine finishining two ends radiating groove;
Operation six: use inner chamber location-plate as fixture, two ends finished radiating groove pushed down by pressing plate, smart unprocessed radiating groove in the middle of fine finishining;
Operation seven: use inner chamber location-plate as fixture, heat sink part pushed down by pressing plate, fine finishining sidewall.
The invention has the beneficial effects as follows: by roughing-Ageing Treatment-fine finishining three step processing, eliminate the distortion of workpiece.
