Abstract
The invention discloses a processing method of a thin-wall semi-shell part. The processing method comprises the following steps of: fixing a thin-wall semi-shell part to be processed on a processing tool, filling gypsum paste in clearances between the thin-wall semi-shell part to be processed and the processing tool, then exposing to air, and after the surface of gypsum paste is cured, heating through an air heater so that the interior of the gypsum paste is entirely cured; and machining the thin-wall semi-shell part to be processed, and taking down the processed thin-wall semi-shell part after processing is finished. The processing method can meet processing requirements of complicated shell parts with different structures and different open areas, the deformation of the processed parts is small, the dimension error of the processed parts is controlled within 0.03mm, the processing precision is high, multi-area processing can be realized by once clamping, and the correlative dimension precision can be ensured. The processing method is especially applicable to processing of complicated shells of open structures and frame type parts of open structures.
Description
Technical field
The present invention relates to the machine components processing technique field, be specifically related to a kind of thin-walled half shell mould machining parts.
Background technology
At present; When processed complex thin-walled half shell mould part, generally all adopt conventional machining process; Choose the Digit Control Machine Tool of the different interlock number of axle according to the part complexity; The wall thickness of part that adopts this kind method processing is generally more than 0.8mm; And for the complicacy half shell mould cavity type parts of wall thickness below 0.8mm because himself intensity and rigidity can't satisfy the force request of process system in the process, therefore adopt the machining process of routine very easily to cause part deformation or cracking.Utilize the method for low-melting alloy can solve the processing problems of the ultra-thin complex parts of approximate closed area; But part for half shell structure; The method of low-melting alloy can't solve; Because the low-melting alloy method is to utilize the pyrocondensation cold expanding raw material of material that part and auxilliary material are linked together; For this half shell structure part; This method can only make bigger that part expands, more yielding or cracking.
Summary of the invention
The object of the present invention is to provide a kind of thin-walled half shell mould machining parts.
In order to realize above purpose, the technical scheme that the present invention adopted is: a kind of thin-walled half shell mould machining parts may further comprise the steps:
(1) fixing thin-walled half shell mould part to be processed: thin-walled to be processed half shell mould part is fixed on the processing tool; Filling full gypsum afterwards in the space between thin-walled to be processed half shell mould part and processing tool sticks with paste; Be placed in the air then; After treating that gypsum is stuck with paste surface cure; The heating of reusable heat blower fan makes gypsum stick with paste inside and also solidifies fully;
(2) processing thin-walled half shell mould part: thin-walled to be processed half shell mould part is carried out machining;
(3) take off the thin-walled half shell mould part that processes: after machining finishes; The processing tool that will have thin-walled half a shell mould part that processes is put into water and was soaked 10～20 minutes; After treating that gypsum is softening; Gypsum and the thin-walled half shell mould part that processes are separated; Take off the thin-walled half shell mould part that processes, clean out.
Wherein, the compound method that said gypsum is stuck with paste is: get calcined gypsum powder for medicine and water, the volume of water is 3 times of calcined gypsum powder for medicine volume, then calcined gypsum powder for medicine is mixed with water, stirs, and makes gypsum and sticks with paste.
Thin-walled half shell mould machining parts provided by the invention; Wherein be employed in the method for filler plaster in the space that forms between part to be processed and the processing tool; Utilize gypsum deformation coefficient in solidification process little and solidify after adhesive property; Part to be processed and processing tool are closely bonded together; And the distortion of part to be processed is little; Because gypsum has certain intensity and hardness after solidifying; Therefore part to be processed can satisfy the force request of process system in the process; The not yielding or cracking of part has been realized the processing of complex thin-wall half shell mould part.
Thin-walled half shell mould machining parts provided by the invention can satisfy the not processing of the housing part of isomorphism type, open area, complicacy; The distortion of the part that is processed into is little; The finished size ERROR CONTROL is in 0.03mm; Machining accuracy is high; No. one time clamping can be realized multizone processing, can guarantee interrelated dimensional accuracy.Thin-walled half shell mould machining parts of the present invention is particularly useful for the processing of wall thickness less than 0.8mm and baroque opening housing part and opening frame part.
The specific embodiment
Embodiment 1
Present embodiment is a specific embodiment of thin-walled half shell mould method of processing parts, and a kind of thin-walled half shell mould part is for certain type head is taken aim at product structure spare; Its steric configuration is complicated, many, the no clamping locating surfaces of free form surface; Wall thickness 0.7mm, local 0.5mm, its processing method may further comprise the steps:
(1) fixing thin-walled half shell mould part to be processed: thin-walled to be processed half shell mould part is fixed on the processing tool; Filling full gypsum afterwards in the space between thin-walled to be processed half shell mould part and processing tool sticks with paste; Do not stay any gap; Be placed in the air then; After treating that gypsum is stuck with paste surface cure; The heating of reusable heat blower fan makes gypsum stick with paste inside and also solidifies fully;
(2) processing thin-walled half shell mould part: thin-walled to be processed half shell mould part is carried out machining;
(3) take off the thin-walled half shell mould part that processes: after machining finishes; The processing tool that will have the thin-walled half shell mould part that processes is put into water immersion 10 minutes; After treating that gypsum is softening; Gypsum and the thin-walled half shell mould part that processes are separated with sharp device; Take off the thin-walled half shell mould part that processes, clean out and get final product.
Wherein, the compound method that gypsum is stuck with paste is: get calcined gypsum powder for medicine and water, the volume of water is 3 times of calcined gypsum powder for medicine volume, then calcined gypsum powder for medicine is mixed with water, stirs, and makes gypsum and sticks with paste.
