Abstract
The invention discloses an integrated balance block and a molding process thereof. The integrated balance block comprises a balance block body. The balance block body is provided with multiple pressing grooves and is cut into multiple connected sub-block bodies through the pressing grooves. Each pressing groove comprises an upper pressing groove body and a lower pressing groove body. The upper pressing groove bodies and the lower pressing groove bodies are oppositely arranged on the upper end face and the lower end face of the balance block body. The bottom faces of the upper pressing groove bodies and the bottom faces of the lower pressing groove bodies are stretched and extruded to form slice type connection belts. Each slice type connection belt comprises a first tearing belt, a second tearing belt and a connection belt body located between the first tearing belt and the second tearing belt. The portions, located at the two ends of each pressing groove, on the two sides of the balance block body are provided with avoiding grooves respectively. The molding process of the integrated balance block includes the steps of firstly, pressing groove molding, secondly, avoiding groove molding and thirdly, cutting off. By the adoption of the integrated structure design, the cut-off amount of waste is small, the material utilization rate is high, the appearance of the steel balance block can be improved, and following process operation convenience can be improved.
Description
Technical field
The present invention relates to balance block technical field, particularly relate to a kind of integral type balance block and forming process thereof.
Background technology
Along with the development of highway in China improvement of terms and automotive technology level is rapid, the moving velocity of vehicle is also more and more faster.If the quality of automotive wheel is uneven, run at high speed in process this, not only can affect traveling comfort by bus, and the undue wear of motor tire and suspension can be increased, increase the difficulty that automobile controls in the process of moving, cause driving dangerous.In order to avoid the generation of this situation, wheel has to pass through specialized equipment before the mounting---and dynamic wheel balancing machine carries out dynamic balancing measurement, in wheel mass, place less than normal increases suitable counterweight, and make wheel keep kinetic balance under High Rotation Speed, this counterweight is exactly wheel balancing block.
At present, domestic and international automobile wheel balance weight mainly contains coupling type and adhesive type two kinds of forms.Coupling type wheel balancing block has installs and removes the advantages such as convenient, but it requires that wheel nave must have a circle flange, to facilitate installation balance block, this has a certain impact to the outward appearance of automotive wheel, installing dismounting on the other hand has cut to scratch to wheel hub, when doing kinetic balance, each position is different, and many scuffings affect appearance looks elegant.In recent years, along with using in enormous quantities and rigors to automobile appearance of aluminium alloy wheel hub of vehicle, superior automobile, even common family car also adopts adhesive wheel balance block one after another, and therefore the market demand of adhesive type balance is very huge.
Adhesive type balance block has plumbous matter, zinc matter, steel material.For a long time, wheel balancing block adopts lead manufacture substantially, and the cost of raw material of the plumbous automobile wheel balance weight manufactured is higher, and more crucially the heavy metal pollution of plumbous balance block generation processed is harmful.In addition, the lead adhesive wheel balance block used at present all adopts extrusion process shaping, and the energy resource consumption of this technique melting lead pig is very high, and its power consumption is several times as much as the energy consumption of die-cast machine.The cost that zinc material pastes balance block is higher, and economic cost performance is not high.Therefore, current trend progressively uses steel balance block.Existing steel material pastes balance block, be made up of multiple single small blocks split back side rubberizing, due to the limitation of Sheet Metal Forming Technology, the section zone of fracture gradient of this small blocks is inconsistent, aesthetic property is not high, another main aspect is that this kind of block Sheet Metal Forming Technology need cut waste material, and stock utilization only has 60% ~ 65%.
