Description
Technical field
The invention belongs to field of machining, be specifically related to
oneplant the extruding method of filling copper lining in steel piece bores.
Background technology
In field of machining, a kind of special construction is had to process, as shown in Figure 1, 2 (only representative structure), copper lining is pressed in steel shell hole, in order to meet the wear-resisting requirement in hole, this structural requirement copper lining matrix is bumped in casing annular groove (as shown in Figure 3,4), and enclosure slot is filled completely, slides in avoiding lining to use.Traditional closing in mode is: design closing in instrument, makes copper lining dilatating and deformable process the closing in of lining in closing in position by the expansion of instrument, there is following shortcoming: one, frock is complicated, manufactures and designs difficulty very large; Two, lagging material is filled uneven in groove, and percent defective is higher.
Summary of the invention
The object of the invention is to utilize the good feature of copper plastic deformation at normal temperatures and provide
oneplant the extruding method of filling copper lining in steel piece bores, use the method, tool making is simple, is convenient to realization, to equipment without excessive demand, utilizes existing ripe process technology and equipment to complete, have good manufacturability.
Object of the present invention and solve its technical problem underlying and realize by the following technical solutions:
oneplant the extruding method of filling copper lining in steel piece bores, first make compression tool, squeeze the curved size increments formula of cutter main body, for rotary structure, squeeze cutter main body by guiding, arc extruding working face, knife bar forms, guide as taper surface, arc extruding working face outside dimension is larger than copper lining aperture, rear stage arc extruding working surface diameter is larger than previous stage, by crowded cutter extruding lining endoporus, aperture is constantly increased, thus copper lining is constantly bumped in steel shell groove, ensure uniform filling in copper bushing coining to the groove in steel shell hole, meet processing request.
The use process of described compression tool is: by the component holes of processing and table vertical, by to crowded cutter cutter spindle to applying pressure, cutter is moved down, under the guiding that crowded cutter guides, crowded cutter vertically enters copper lining endoporus, when first arc extruding working face enters copper bush hole, because arc extruding working face outside dimension is larger than aperture, bush hole is in radial direction generation plastic deformation under the extruding of curved working face, and lining matrix extends in groove; Because rear stage curved working face diameter is larger than previous stage, aperture under the extruding of crowded sword arc shape working face, lining aperture becomes large gradually, increases gradually the distortion of radial direction is also corresponding, lagging material is full of in groove.
The number of described arc extruding working face can be determined according to the traveled distance of forcing press and part actual size.
When the volume of described steel shell groove domestic demand filling is larger, crowded cutter can be pressed diameter dimension grouping, substep is processed.
The present invention compared with prior art has obvious advantage and beneficial effect.From above technical scheme, the present invention compares with traditional processing mode and has following characteristics:
1, squeeze knife structure simple, be rotary structure, design and manufacture cost is cheap.
2, method of operating is easy to grasp, and can meet design requirement completely.

Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, to what propose according to the present invention
oneplant extruding method detailed description of the invention, feature and the effect thereof of in steel piece bores, filling copper lining, be described in detail as follows.
See Fig. 5-9,
oneplant the extruding method of filling copper lining in steel piece bores, first make compression tool, squeeze the curved size increments formula of cutter main body, for rotary structure, as Fig. 5, shown in 6, squeeze cutter main body by guiding 3, arc extruding working face 4, knife bar 5 forms, 3 are guided to be taper surface, arc extruding working face 4 outside dimension is larger than copper lining aperture, rear stage arc extruding working face 4 diameter is larger than previous stage, by crowded cutter extruding lining endoporus, aperture is constantly increased, thus copper lining 2 is constantly bumped into steel shell 1 groove C1, C2, in C3, view before and after closing up is as Fig. 7, 8, shown in 9, ensure copper lining 2 to be expressed to uniform filling in the groove in steel shell 1 hole, meet processing request.
The use process of described compression tool is: by the component holes of processing and table vertical, by axially applying pressure to crowded cutter knife bar 5, cutter is moved down, guide the guiding of 3 at crowded cutter under, crowded cutter vertically enters copper lining 2 endoporus, when first arc extruding working face 4 enters copper lining 2 hole, because arc extruding working face 4 outside dimension is larger than aperture, bush hole is in radial direction generation plastic deformation under the extruding of curved working face, and lining matrix extends in groove; Because rear stage curved working face diameter is larger than previous stage, aperture under the extruding of crowded sword arc shape working face, lining aperture becomes large gradually, increase gradually the distortion of radial direction is also corresponding, make lagging material be full of groove C1, C2, C3, the view before and after closing up as Figure 7-9.
The number of described arc extruding working face 4 can be determined according to the traveled distance of forcing press and part actual size.
When the volume of described steel shell 1 groove domestic demand filling is larger, crowded cutter can be pressed diameter dimension grouping, substep is processed.
Concrete steps are as follows:
1, the designing and producing of closing in squeezing knife tool:
(1) manufacture of this cutter is to material without particular/special requirement, can reach hardness requirement >=HRC after only needing heat treatment, completes the processing of profile by designing requirement on numerically controlled lathe, arc extruding working face 4 is reserved the allowance for finish of 0.02; (2) heat-treat, ensure cutter hardness requirement; (3) fine finishining is ground, polishing arc extruding working face 4, guiding 3 and knife bar 5, ensure that surface roughness and dimensional requirement (also can add two ends centering in man-hour in turner, stay fine grinding surplus to polishing arc extruding working face 4, knife bar 5, after grinding, polishing ensures surface roughness and dimensional requirement again);
2, the processing of steel part housing bore and cannelure is completed;
3, complete the processing of copper lining, and the allowance of 1mm is reserved in hole, ensure the tightness of complete external diameter and housing bore 0.03-0.05;
4, lining is put into liquid nitrogen to cool, then put into housing bore;
5, the extruding closing in of lining has been extruded by size increments formula;
6, complete the processing of semifinishing to gland closing in backsight trepanning and hole inner ring type groove, and grind is stayed to bush hole;
7, lappingout endoporus, ensures dimensional accuracy, surface roughness requirements.
In sum, use this closing method, tool making is simple, is convenient to realize, to equipment without excessive demand, utilizes existing ripe process technology and equipment to complete, have good manufacturability.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, anyly do not depart from technical solution of the present invention content, the any simple modification done above embodiment according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
