1, aluminium bar cutting:
Select automatic programmable aluminium bar cutting machine, complete from aluminum extrusion cutter by each element workpiece of PLC programmable storage control machine, only need once set, then starting switch, machine can complete the functions such as material folding, cutting, feeding, counting automatically, operating efficiency and good processing accuracy, the bright and clean impulse-free robustness of cutting material section.
2, tunnel heating furnace (circular furnace)
Products characteristics:
High energy-conservation: heated by natural gas, energy consumption 20m3/ ton, comparatively common heating furnace saves 10m3/ ton.
High-quality: cylindrical structure, in conjunction with heat energy Inner eycle control system, to make in stove temperature equalization everywhere, guarantees aluminium bar thermally equivalent;
, never there is raw rod, excellent bubble, molten excellent phenomenon in high control: the actual temperature that accurately can control aluminium bar;
High intelligence: system is controlled by PLC touch-screen, to warm-up time, warm temperature, the identification of aluminium bar material automatic Memory, and realizes Automatic Control;
Less manpower: enter rod, go out rod all operated by robot arm, efficiency is high.
3, forge and press
Finish forge hydraulic test feature:
Prestressing technique is very important design and manufaction means for heavy hydraulic press.Due to prestressed applying, change the stress of original structure, played material and there is feature compared with high fatigue life in a compressed state, effectively improved intensity and the anti-fatigue performance of structure member, alleviate construction weight, make it easier processing and manufacturing.
Framework for support in heavy-duty machinery design has overall sheet frame rack construction, bolt prestressed structure and steel wire winding prestressed structure three major types, the latter can reach the highest technology-economic indicator, being the developing direction of heavy-duty machinery design in modern age, is the first-selection of heavy hydraulic press body construction design.
As preload piece, pretension is carried out to low-intensity material (column) with high-strength material (cold drawn wire), utilize poor rigidity, groundwork load is born by preload piece by low intensive, but be in compressive stress state all the time by preload piece, and the preload piece of high strength only bears sub-fraction load, be close to as dead load.The two all has high fatigue life.Preload piece is with larger by the intensity difference of preload piece, and poor rigidity is larger, and the effect of pretightning force is more obvious.Steel wire allowable stress is high: σ b>1600MPa, and allowable stress can reach 800MPa, high reliability: Low rigidity is than C (0.15 ~ 0.2), and steel wire stress fluctuation little (0 ~ 5%), can be considered static load.Therefore, steel wire winding prestressed structure has important value for solving the processing of the key components and parts such as heavy stamp forging hydraulic press framework for support, master cylinder, manufacture and Fatigue Life Problems
4, aluminium alloy wheel hub rotary pressure technology feature:
Dimensional accuracy is high, and following process amount is little or do not process;
Material anti-fatigue ability, intensity, yield point, tensile strength and hardness significantly improve.Production process is few, and production efficiency is high;
Stock utilization is high, and the wheel hub being applicable to different size is produced, and cost is low.
5, fixation rates technical characterstic:
Be applicable to the solution treatment to large and medium-sized alloy product parts and Ageing Treatment;
This equipment specializes in aluminium alloy wheel hub aging strengthening model;
This equipment and electrical control support the use, and have very high automatic degree;
Without charging basket wheel hub heat treatment production line device advantage: waste heat recovery, workpiece temperature are evenly, economical and energy saving, workpiece mechanical performance promote.
6, machined and inspection
Full-automatic machine is selected to process complete unit
Equipment and technology feature:
Full PLC controls, and automation efficiency is high.
Full mechanical arm controls, and production precision is high.
Manual maintenance is few, and production cost is low.
The utility model system produce wheel hub and carry out analysis result figure as shown in Figure 2 by the wheel hub that casting technique is produced:
It is very good that metallographic dissects forged hub (left side) performance
The tangent plane lubrication very of forged hub, metallic molecule is put tight without harsh feeling, and the metallic molecule of casting hub (right side) is put loose, and metallic particles comparatively greatly and tangent plane has very strong harsh feeling.
Check under the microscope, the metallic molecule of right side casting hub puts discrete particles comparatively greatly, and the metallic molecule of left side reflectal wheel hub is put very tight.It is tighter that metallic molecule is put, and the fatigue durability of wheel hub is higher, and anti-impact force is stronger, and bearing capacity is better.
Outward appearance is difficult to difference component difference
Some casting hub outward appearance imitates the characteristic of forging, such ordinary consumer is just difficult to distinguish, but both have relatively big difference in metallic character, the fatigue durability of forged hub, anti-impact force, intensity are higher relative to casting hub, and both do not have too large difference on heat sinking function.But up-to-standard casting hub generally weighs about 20% than forged hub.
Therefore adopt the utility model system forging aluminium alloy wheel rim, the lightweight of aluminum-alloy wheel can be played, good heat dissipation, the advantage that dimensional accuracy is high.
Above-described embodiment is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
