Description
Technical field
The invention belongs to tire assembly drum technical fields, and in particular to a kind of motorcycle racing car Special tire shrinks sizing automatically
Drum.
Background technique
Currently, in the market small dimension motorcycle racing car Special tire setting drum due to rolling mechanism, ultra-narrow using bandwidth and
Molding machine gas circuit (can only provide compressed air all the way) is limited, and inadequate space installs the spring mechanism for being used to shrink after sizing additional,
Contracting drum can not be realized in technique requires.
Even if tying up space is mounted with spring retraction mechanism, due to the metal fatigue that spring often occurs in process of production
It frequently can lead to failure, to reduce production efficiency.
Summary of the invention
To solve the deficiencies in the prior art, the present invention provides a kind of motorcycle racing car Special tire and shrinks setting drum automatically, makes
Drum speed is contracted faster with pneumatic contracting convexity-ratio spring, effectively improves production efficiency.
To solve the above problems, technical solution provided by the invention are as follows:
A kind of motorcycle racing car Special tire shrinks setting drum, including left side drum and right-hand drum, the left side drum and right-hand drum automatically
It is mounted on the main shaft of molding machine by axle sleeve respectively, the left side is bulging and right-hand drum is equipped with cylinder power device and contraction
Circle, the periphery of the shrink-ring are equipped with tyre bead locking device, and the cylinder power device includes rise air-blowing cylinder, contracting air-blowing cylinder, work
Plug and air storage chamber, the piston are equipped with Non-return air valve, and rise air-blowing cylinder and the air storage chamber described in the Non-return air valve connection.
Further, the tyre bead locking device is annular groove.
Further, the shrink-ring is made of plural block bracer.
Further, the bracer is fixedly connected with a slide block, and the sliding block and connecting rod are hinged, and the connecting rod and slide connect
It connects.
Further, the piston is equipped with limiting buffer block.
Compared with prior art, motorcycle racing car Special tire of the present invention shrinks setting drum automatically, and air flue provides inside main shaft
Compressed air, slide in compressed air-driven setting drum are simultaneously filled with compressed gas to air storage chamber by check valve, realize sizing
Blow-up contracting；After closing compressed air, the compressed air of air storage chamber provides pressure and realizes contracting drum.Due to reducing spring mechanism,
To provide space to meet production technology, and drum speed is contracted faster using pneumatic contracting convexity-ratio spring, effectively improve
Production efficiency.In addition, due to there is no spring mechanism, being not in spring during generation compared to commonly structure setting drum is determined
The metal fatigue of appearance effectively reduces failure rate, also improves production efficiency to a certain extent.

Specific embodiment
Technical solution of the present invention is described in further detail below in conjunction with specific embodiments and the drawings.
Embodiment 1
As shown in Figure 1, a kind of motorcycle racing car Special tire shrinks setting drum, including left side drum and right-hand drum, the left side automatically
Bulging and right-hand drum passes through axle sleeve 1 respectively and is mounted on the main shaft of molding machine, and the left side is bulging and right-hand drum is equipped with cylinder power
Device and shrink-ring, the periphery of the shrink-ring are equipped with tyre bead locking device, and the tyre bead locking device is annular groove, described
Shrink-ring is made of plural block bracer 2, and the bracer 2 is fixedly connected with sliding block 3, and the sliding block 3 and connecting rod 4 are hinged, the company
Bar 4 is connect with slide 5, and the cylinder power device includes rise air-blowing cylinder 6, contracting air-blowing cylinder 7, piston 8 and air storage chamber 9, the work
Plug 8 is equipped with Non-return air valve 10, and the Non-return air valve 10 is connected to rise air-blowing cylinder 6 and the air storage chamber 9, on the piston 8
Equipped with limiting buffer block 11.
The operation principle of the present invention is that: when expansion starts, the air-blowing cylinder 6 that rises is filled with compressed air and piston 8 is pushed to move, and leads to
Non-return air valve 10 is crossed to 9 injecting compressed air of air storage chamber up to 9 pressure balance of air-blowing cylinder 6 and air storage chamber of rising, due to the air-blowing cylinder 6 that rises
Pressure comparison is not counted in than the fixation of 9 space of contracting air-blowing cylinder 7(air storage chamber) compression effective area is bigger, so the generation of air-blowing cylinder 6 of rising
Thrust ratio contracting air-blowing cylinder 7 it is bigger, so the constant drum until restraining position realization is risen of 5 direction of motion of slide.
When contraction, the compressed air in gas circuit stops supply, and 6 pressure of air-blowing cylinder that rises drops to normal barometric pressure level, gas storage
The compressed air of room 9 flows into contracting air-blowing cylinder 7 and provides pressure promotion 8 counter motion of piston realization contracting drum.The present invention is for production work
Skill, redesigns and optimizes drum body structure, and enable to meet ultra-narrow bandwidth uses and roll needed space.Since contracting is roused
When, sliding block 3 has tied up the space of installation spring retraction mechanism, and bulging external structure limited by technique, so be provided with one with
The air storage chamber 11 that piston 8 moves provides needed power when contracting is roused for piston 8.
Above embodiments only use to further illustrate the technical scheme of the present invention, but the invention is not limited to embodiments.
Any simple modification, equivalent variations and modification made to the above embodiment according to the technical essence of the invention, each fall within
In the protection scope of technical solution of the present invention.
