Description
Technical field
The present invention relates to balance weight technical field more particularly to a kind of monoblock type balance weight and its moulding process.
Background technology
It is quickly grown as highway in China improvement of terms and automotive engineering are horizontal, the travel speed of vehicle is also increasingly
Soon.If the quality of automotive wheel is uneven, during this run at high speed, comfort by bus can be not only influenced, but also
Automobile tire and the irregular wear of suspension can be increased, increase the difficulty that automobile controls in the process of moving, cause to drive a vehicle
It is dangerous.In order to avoid this kind of situation, wheel has to pass through special equipment before the mounting --- dynamic wheelo balancer
Device carries out dynamic balancing measurement, increases counterweight appropriate at wheel mass place less than normal, wheel is made to keep dynamic balancing under high speed rotation,
This counterweight is exactly wheel balancing block.
Currently, automobile wheel balance weight mainly has two kinds of forms of coupling type and adhesive type both at home and abroad.Coupling type wheel balance
Block has many advantages, such as to be convenient to mount and dismount, but it requires hub for vehicle wheel that must have a circle flange, and to facilitate installation balance weight, this is to vapour
The appearance of vehicle wheel has a certain impact, and on the other hand installation dismounting has cut scuffing to wheel hub, does each position when dynamic balancing
Difference, a plurality of scuffing influence appearance looks elegant.In recent years, as the high-volume of aluminium alloy wheel hub of vehicle uses and to automobile appearance
Rigors, superior automobile or even common family car also use adhesive wheel balance weight one after another, therefore adhesive type balances
Market demand it is very huge.
Adhesive type balance weight has lead matter, zinc matter, steel material.For a long time, wheel balancing block uses lead to manufacture substantially,
The cost of raw material of the automobile wheel balance weight of lead manufacture is higher, the heavy metal pollution pair that more crucially lead balance weight generates
Human body is harmful.In addition, lead adhesive wheel balance weight used at present is all made of die-casting process molding, which melts lead pig
Energy consumption it is very high, power consumption is several times as much as the energy consumption of die casting machine.The cost that zinc material pastes balance weight is higher, warp
Cost performance of helping is not high.Therefore, current trend is gradually to use steel balance block.Existing steel material pastes balance weight, is
It is made of multiple single small blocks split back side rubberizings, due to the limitation of Sheet Metal Forming Technology, the section of this small blocks is broken
Layer gradient is inconsistent, and aesthetics is not high, and another main aspect, which is such block Sheet Metal Forming Technology, need to cut waste material, and stock utilization only has
60%~65%.
