Abstract
The utility model provides a kind of building drum supporting block mechanism for producing 17.5 cun of tires, the bracer mechanism forms deep trouth, the deep trouth is in class triangular groove, such triangular groove has first slope and the second slope, the first slope and the second slope intersection form bending part, which designs in rounded corner, wherein, the bottom angle of first slope and bending part is 15 °~20 °, and the bottom angle of the second slope and bending part is 50 °~70 °.The gradient of building drum supporting block mechanism provided by the utility model, the second slope increases, bracer depth down, in this way, compacting fetus, prevents from deviating.Rounding designs between two gradients, and bracer cooperates closer with fetus.First slope integrated design provided by the utility model, angle are 17 °, and improvement rear profile curve transition is gentle, no recess, convenient for compacting fetus.
Description
Technical field
The utility model belongs to field of tire production, in particular to a kind of building drum supporting block machine for producing 17.5 cun of tires
Structure.
Background technique
Currently, tire production system all refers to the bracer of fastening carcass structure both at home and abroad.Bracer shape is deep groove shape,
As CN201309264Y disclose the mechanical anti-package of the fitting for being able to achieve other glue components of tire, compacting and positioning a kind of at
The bracer mechanism of type drum, specific structure is the diamond shape slot that bracer is designed to that bottom edge bevel edge is 15 °, is combined into a big circle
Slot, placed in the circular trough corresponding shape sealed rubber ring be tightly connected in use, bracer rise locking steel wire circle when,
Due to its special imitative type structure, will not generating means displacement, positioning accuracy when improving molding；And the structure of bracer is in fetus
When inflating overdetermination type clamping action can be furnished with to wire loop two sides carcass；However there are above-mentioned same defects.
As shown in Figure 1,15 ° of drop center rim curves that 17.5 cun of Series Tyres use；For the shape for cooperating 15 ° of drop center rims
Shape, the bead curve of my company's tire design substantially with wheel rim curve always.Wire loop uses oblique hexagonal design, bottom edge
Tilt angle is 15 ° as shown in Figure 2；Because 15 ° of angles are arranged at wire loop bottom, at the time of molding such as bracer shape and wire loop base material
Cooperation, which is not easy to produce then closely, chokes with resentment.Original building drum supporting block structure is as shown in figure 3, bracer shape inside the our company of tire
Complexity, bottom platform is wider, and the right side gradient is steep, bracer depth as shallow；There are two angles in left side, form recess, are bonded not with fetus
Closely, it presses not firm.Above-mentioned existing two kinds of bracers are misfitted with my company's fetus bead curve, therefore in molding fetus
Tire bead bubble is more, occurs skin hole after vulcanization, just can be carried out sale after being repaired, and influences production effect
Rate increases production cost.
Summary of the invention
The utility model provides a kind of building drum supporting block mechanism for producing 17.5 cun of tires, and the bracer mechanism forms depth
Slot, the deep trouth are in class triangular groove, such triangular groove has first slope and the second slope, the first slope and the second Slope Facies
Bending part being formed at friendship, which designs in rounded corner, wherein the bottom angle of first slope and bending part is 15 °~
20 °, and the bottom angle of the second slope and bending part is 50 °~70 °.
As an improvement, the bottom angle of first slope and bending part is 17 °.
As an improvement, the bottom angle of the second slope and bending part is 60 °.
The gradient of building drum supporting block mechanism provided by the utility model, the second slope increases, bracer depth down, this
Sample is compacted fetus, prevents from deviating.Rounding designs between two gradients, and bracer cooperates closer with fetus.
First slope integrated design provided by the utility model, angle are 17 °, and improvement rear profile curve transition is gentle,
Without recess, convenient for compacting fetus.
Detailed description of the invention
Fig. 1 is 15 ° of drop center rim curves that 17.5 cun of Series Tyres use；
Fig. 2 is the wire loop structure schematic diagram of the bead of tire design；
Fig. 3 original molding machine original bracer shape and structure schematic diagram；
Fig. 4 is the side view of bracer mechanism provided by the utility model.
Specific embodiment
As shown in figure 4, a kind of building drum supporting block mechanism for producing 17.5 cun of tires, the bracer mechanism form deep trouth, it should
Deep trouth is in class triangular groove 1, such triangular groove 1 has first slope 2 and the second slope 3, the first slope 2 and the second slope 3
Intersection forms bending part 4, which designs in rounded corner, transitions smooth, and cooperation is close, wherein first slope 2 and rounding
The bottom angle of angle bending part 4 is 15 °~20 °, and the second slope 3 and the bottom angle of rounded corner bending part 4 are 50 °~70 °.
In the present embodiment, the bottom angle of first slope and rounded corner bending part is 17 °, the bottom on the second slope and rounded corner bending part
Portion's angle is 60 °.As shown in Figure 1, building drum supporting block mechanism provided by the utility model, the gradient on the second slope increases, support
Block depth down, in this way, compacting fetus, prevents from deviating.Rounding designs between two gradients, and bracer cooperates closer with fetus.
First slope integrated design provided by the utility model, angle are 17 °, and improvement rear profile curve transition is gentle,
Without recess, convenient for compacting fetus.
Using bracer structure provided by the utility model, in actual production, by statistics, improving productivity
36.6, consumables cost decline 17.5%, rolling resistance decline 6.3%.
Schematically the utility model and embodiments thereof are described above, actual structure is not limited to
This.So if those of ordinary skill in the art are inspired by it, without deviating from the purpose of the present invention,
Frame mode similar with the technical solution and embodiment are not inventively designed, should belong to the protection of the utility model
Range.
