The operation of workpiece and cooling condition during the quenching of molding sheet metal component
Before workpiece quenching, for ensureing that workpiece can be put in clamping device lower mold smoothly, lower mold need to be exposed on liquid level, by people
Workpiece is transferred in lower mold by work smoothly；During workpiece quenching, for ensure workpiece in quenching liquid sufficiently cool, need to possess workpiece energy
It is completely immersed in quenching liquid；Workpiece and upper and lower mould are designed as avoiding the point cantact of quenching soft spot.
Require according to above-mentioned technology: the area of support and height will be according to the size of sheet-metal formed part and field quenching liquid baths
Volume and the height of liquid level determine.The fixing dependence of support is welded in the slotted-angle shelving on support and the connection on quenching liquid bath
Body is fixed.Frame bottom does not contacts with cell body bottom surface, and to keep quenching liquid bath not affected by clamping force, its strength born is complete
Portion is undertaken by quenching tank edge or external structure support；Lower mold is exposed will while liquid level relies on the high car pull-up that quenches to open upper mold
Lifting on whole device and make lower mold expose liquid level, impulsive force during the high car that quenches pull-up relies on four spring buffers above.
For example, it is assumed that the degree of depth in quenching liquid tank liquor face is 2000, require to be positioned under liquid level 200～300 after Work-sheet pressing deep
Place, then the height in support immersed in liquid level should be less than the degree of depth of quenching liquid bath.The Prestress design of upper and lower mould should be with on workpiece
After mould contacts with lower mold, the pretightning force of spring is sufficient to meet after making Workpiece clamping quenching indeformable.
For improving being fully contacted and the mobility of quenching liquid of workpiece and quenching liquid, the upper and lower mould directly contacted with workpiece sets
It is calculated as mesh-shape and pin feature.Mesh plays quenching liquid and leads to leakage effect, and pin and workpiece point cantact avoid workpiece quenching soft spots.
