Description
(1) technical field:
The present invention relates to tire production equipment, specifically is a kind of assembly drum of all-steel meridian large tyre-forming machine.
(2) background technology:
The assembly drum of the tape drum shoulder that uses on the tyre building machine at present, as the patent No. is that 200620083428.8 shaping drum for tyre shaping machine is the most representative, this assembly drum comprises wide, narrow drum watt contracting mechanism, wide, a narrow drum watt contracting mechanism edge is enclosed within on the main shaft of hollow, drive by the feed screw nut's transmission in the hollow main shaft, wide, a narrow drum watt contracting mechanism is expanded in proper order and shunk, make wide, narrow drum watt maximum and be retracted to the diameter minimum, to satisfy technological requirement at the radially asynchronous diameter that is expanded to.Also include wide, narrow drum watt drum shoulder retractor device simultaneously in wide, the narrow drum watt contracting mechanism by bent connecting rod and watt contracting mechanism interlock of wide, narrow drum, be accompanied by the expansion and the contraction of wide, narrow drum watt contracting mechanism, wide, a narrow drum watt drum shoulder stretches vertically and shrinks, and brings convenience for material loading and blanking.
Facts have proved, above-mentioned shaping drum for tyre shaping machine is applicable to the production of middle-size and small-size tire, because the development tire of industry is done bigger and bigger, as engineering tire, huge tire etc., the shaping drum for tyre shaping machine of said structure can't satisfy the production requirement of engineering tire, huge tire etc. because of reasons such as it is axial, poor, wide, the narrow drum of radial stability watt drum shoulder amount of contraction deficiencies.
The patent No. is that 200710050947.3 shaping drum for tyre shaping machine improves the structure of above-mentioned assembly drum for this reason, at first be to make watt drum shoulder retractor device self-movement operation of wide, narrow drum, and the influence that not moved by wide, narrow drum watt contracting mechanism brings convenience for material loading and blanking; Wide in addition, narrow bulging contracting mechanism adopts by wide, the narrow drum watt linkage that long and short connecting rod constitutes, and satisfies the production requirement of engineering tire, huge tire.
But it is not high that also there is complex structure in the improvement of doing, a watt drum is takeed on telescopic section intensity, and reliability is low, and the problem of inconvenience is installed in operation and manufacturing.
(3) summary of the invention:
Weak point at above-mentioned shaping drum for tyre shaping machine, to the purpose of this invention is to provide a kind of drum shoulder and wide drum watt, narrow drum watt be an integral body, do not need to be provided with specially wide, narrow drum watt drum shoulder retractor device, can adjust the assembly drum of all-steel meridian large tyre-forming machine of assembly drum width and high reliability.
The present invention is achieved in that this kind assembly drum of all-steel meridian large tyre-forming machine comprises wide drum watt group and narrow drum watt group, wide drum watt group and narrow drum watt group harmomegathus mechanism and power drive mechanism thereof, power drive mechanism comprises hollow main shaft and is built in the screw mandrel mandrel of hollow main shaft, there are two segment length to equate on the screw mandrel mandrel, the screw thread that rotation direction is opposite, cooperating the opposite feed screw nut pair of two cover rotation directions, when the screw mandrel mandrel rotated, pair of nut reverse sync on screw mandrel in the left and right sides moved; Drive with left and right sides pair of nut fixing drive sleeve hollow main shaft axially on slide, make and to be hinged on the wide drum watt connecting rod on drive sleeve and the drum watt seat and narrow drum watt connecting rod promotes wide drum watt group respectively and a narrow drum watt group is opened and shunk, the axis of wide drum watt connecting rod and hollow main shaft near or when arriving 90 °, wide drum watt group and narrow drum watt group are intervally arranged on the circumference that with the hollow main shaft is axis and form a desirable circle drum.
Distance between both sides narrow drum watt connecting rod and drive sleeve hinge is decorateeed is cut with scissors distance between decorateeing less than both sides wide drum watt connecting rod and drive sleeve, and the length of narrow drum watt connecting rod is greater than the length of wide drum watt connecting rod, narrow drum watt connecting rod and narrow drum watt seat hinge is decorateeed apart from the distance of narrow bulging tiling and is cut with scissors the distance of decorateeing apart from wide bulging tiling less than wide drum watt connecting rod and wide drum watt seat, to realize sequenced asynchronous contraction and spreading between wide drum watt group and the narrow drum watt group.
A wide drum watt group and narrow drum watt group is formed drum watt group, drum watt group is all to adorn the bulging tile fragment that a tape drum is takeed on about on the drum watt seat, constitute with the drum watt wide tile fragment of accent of centre, be wide drum watt group by about the wide drum watt of two band inverted cone shape drum shoulders and wide drum of a middle interconvertible wide accent watt form, narrow drum watt group by about the narrow drum watt of two band taper drum shoulders and wide drum of a middle interconvertible narrow accent watt form.
On the drum watt seat feather key is housed, the bulging tile fragment of tape drum shoulder can slide on feather key, draws back the bulging tile fragment of tape drum shoulder, changes the wide bulging tile fragment of different middle tones, just can form the width of different drums.The angle of the chamfering of the bulging tile fragment of the tape drum shoulder of wide drum watt group and narrow drum watt group is a supplementary angles.The both sides of drum watt seat are fixed with line slideway, and the slide block of line slideway is fixed on the positioning disk of both sides, rouses watt group like this and just can slide on positioning disk under the promotion of connecting rod
The length of the gathering sill that the confession nut sleeve key opened on the hollow spindle slides has determined the maximum of narrow drum watt and wide drum watt to open diameter and minimum of contraction diameter.
Advantage of the present invention:
1, adopt connecting rod to cooperate the sliding pair structure in wide, narrow watt of harmomegathus mechanism of the present invention, the precision height, good rigidly, stability can be born very big radially operating pressure by force.
2, wide, the narrow drum of the present invention watt drum shoulder and wide, narrow drum watt integral manufacturing need not be provided with drum shoulder telescoping mechanism in addition, not only bears bigger axial force, and simplified mechanism.
3, this assembly drum can double-deck folding simultaneously the contraction reach enough little constriction radius when shrinking, and can reach the major diameter of technological requirement when upholding again, has increased the convenience of producing, and has alleviated labour intensity, has improved production efficiency.
4, this assembly drum is unclamping surface drum watt screw, just can change the wide drum of accent watt of centre, so just can become the assembly drum of same specification different model, has increased the convenience of flexible production, has alleviated labour intensity, has improved production efficiency.
5, comprehensively above-mentioned, the present invention is fit to the tire production of any specification kind, particularly has advantage in the production of huge tire, engineering tire.
