Description
Technical field
The present invention relates to a kind of steel wheel balance fritter and strip wheel balancing block, and produce the diel of steel wheel balance fritter and produce the method for steel wheel balance fritter.
Background technology
At present, domestic and international automobile wheel balance weight has external hanging type and built-in adhesive type two kinds of forms.External hanging type wheel balancing block has installs and removes the advantages such as convenient, but it requires that wheel hub must have a circle flange, and to facilitate plug-in balance block, this has a certain impact to the outward appearance of automotive wheel, also has the risk come off on the other hand, easily occurs safety problem.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 built-in adhesive wheel balance block one after another, calculate by the balance block of standard configuration ten Different Weight of a car, market demand is very huge.
For a long time, wheel balancing block adopts plumbous manufacture substantially, and the cost of raw material of the plumbous automobile wheel balance weight manufactured is higher, and more plumbous balance block processed not only lead steam and lead powder dirt generation heavy metal pollution when producing, also has grievous injury to human body.Particularly after rejection of car, the balance block on wheel has just become waste.The balance block gone out of use, after exposing to the sun and rain, just has overproof plumbous stripping and to permeate the ground water, have great harm to human body and environment.Restriction and progressively superseded plumbous balance block processed are the manufacturing common recognitions of international automobile, and unleaded production is as the important symbol of environmentally friendly vehicle.In addition, the lead adhesive wheel balance block of current use all adopts extrusion process shaping, first by lead pig melting, then plumbous liquid must be injected into cooling forming in molding die before casting forming, the energy resource consumption of melting lead pig is very high, and its power consumption is several times as much as the energy consumption of die-cast machine.Metal liquid die cast is the high energy consumption industry of social recognition, does not meet the industry policy of energy-saving and emission-reduction and sustainable development.
Current trend adopts other metal to replace lead metal to make built-in adhesive wheel balance block, replaces the built-in adhesive wheel balance block of traditional die cast with stamping forming adhesive wheel balance block.Production method the most frequently used is at present cut off.Fig. 4 shows this process.After one end of long blank 43 is located by locating piece 42, by the cutter 41 of part of the upper die and the bottom knife 44 of part of the lower die by the cutting workpiece of specified length.Because the equal one side of scissors mouth of cutter and bottom knife composition is stressed, the inclination that certain angle all occurs for the upper bottom surface of stamping-out section and workpiece and bottom surface can be there is in workpiece when cutting off, namely no longer vertical between stamping-out section and the upper bottom surface of workpiece, this causes to be cut on the shearing section of workpiece and occurs larger angle of collapsing, and along with the wearing and tearing of shear blade cutting edge, collapsing angle can be increasing, has a strong impact on the cross section quality of part.This defect is difficult to avoid on shearing die.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, providing a kind of steel wheel to balance fritter and strip wheel balancing block, and produce the diel of steel wheel balance fritter and the production method of steel wheel balance fritter.Adopt this technical scheme, the wheel balance fritter obtained, two ends all have evenly without the stamping-out section at angle of collapsing.Meanwhile, avoid the energy consumption of die cast, and there is higher production efficiency.
In order to solve the problems of the technologies described above, a kind of steel wheel balance fritter, comprise can with the bottom surface of sticking double faced adhesive tape;
Described steel wheel balance fritter has overall stamping forming integral structure, and described steel balance fritter two ends along its length have evenly without the stamping-out section at angle of collapsing.
Further, the cross sectional shape of described steel wheel balance fritter stamping-out section is isosceles trapezoid, and described is the bottom surface on the long limit of corresponding described stamping-out section with the bottom surface of sticking double faced adhesive tape.
Another technical scheme provided by the invention is: a kind of strip wheel balancing block, it is characterized in that the bottom surface of the steel wheel balance fritter described in described strip wheel balancing block is pasted onto glue face, double faced adhesive tape side gained, the stamping-out section of the wheel balance fritter described in during stickup is parallel with the length direction of described double faced adhesive tape.
Another technical scheme provided by the invention is: a kind of diel of producing steel wheel balance fritter, comprises feed zone,
Described feed zone arranges feed zone holding pad, and described feed zone holding pad top is connected with punch retainer;
Described diel also comprises: some punch sections and some positioning sections; Described positioning section and punch section are arranged at interval successively along the feedstock direction of steel plate blank, and described positioning section and punch section have identical length along feedstock direction; Described in last, the end of positioning section arranges locating piece;
Each described positioning section all arranges positioning section holding pad, and described positioning section holding pad top is connected with described punch retainer;
Each described punch section all arranges punch section punch and punch section blanking die, and described punch section punch top and described punch retainer are fixed.
Further, also arrange embossing station between described feed zone and first described punch section, described embossing station comprises the embossing station punch be fixed on punch retainer, and the length of described embossing station punch in the vertical direction is less than punch section punch.
Another technical scheme provided by the invention is: a kind of method of producing steel wheel balance fritter, described production method is carried out in above-mentioned diel, and described production method comprises the steps:
Feeding step, sends the steel plate blank with uniform cross-section shape into described diel, makes described plate slab stub bar end surface be resisted against on the medial surface of described locating piece;
Fixing step, described feed zone holding pad, all positioning section holding pads and described locating piece combined action, fixing described steel plate blank;
Blanking step, the punch section punch stamping-out steel plate blank of described diel, obtains the finished product of steel wheel balance fritter simultaneously at some positioning sections of described diel and some punch sections.
Further, described steel plate blank is drawn shaping by round steel.
Further, while carrying out described blanking step, also carry out imprint step, namely the upper surface of described embossing station punch to the steel plate blank being positioned at described embossing station impresses.
Steel wheel balance fritter of the present invention has evenly without the stamping-out section at angle of collapsing, and this is owing to have employed special cut die in its production process.Cut die are at the overall stamping-out in blanking place, and former and later two sections of the section of being stamped are stamping-out simultaneously, punch section punch and die uniform force, and the steel plate blank section be punched can not run-off the straight; Overall stamping-out, makes front and back section smooth.Positioning section equals the length of punch section along the length on feedstock direction simultaneously, is pushed down during stamping-out by positioning section holding pad and feed zone holding pad, and after stamping-out completes, positioning section is also that a qualified steel wheel balance is soon little.Like this, one time stamping-out obtains multiple part identical in quality, not only solves section and to collapse an angle difficult problem, also make production efficiency significantly improve.
