Description
(1) technical field:
The utility model relates to the tire forming vulcanizer parts, specifically is a kind of capsule apparatus that changes of tire forming vulcanizer central authority.
(2) background technology:
The central authority of existing hydraulic pressure vulcanizing machine serves as the type that better is suitable for the Type B central authority, because the capsule and the sealing device of central authority all are to work under the environment of HTHP, its service life is low, especially sealing device is easy to damage, sometimes will finish changing repeatedly in one day, each replacing all needs capsule is taken off.Capsule is fixing by upper and lower capsule chuck in the described Type B central authority, last capsule chuck and center bar are fixing can not to be become flexible, but following capsule chuck is to fixedly connected with ring seat by T shape screw thread, and this structure makes by playing the capsule chuck that the replacing of capsule is needed the long period; Playing the capsule chuck in addition is to be screwed into by T shape screw thread to compress the sealing that sealing ring guarantees central authority, and the capsule chuck does not screw in the leakage that will cause high-temperature high-pressure medium in the capsule fully instantly.
In addition, the distortion that is distorted of capsule after the expanding-contracting action of central authority makes and vacuumizes, the flexible capsule of distortion makes its rotation to the power that capsule chuck down applies, and will play the capsule chuck to unscrew easily, cause down the capsule chuck can't compress sealing ring, also can cause the leakage of high-temperature high-pressure medium in the capsule.
(3) utility model content:
At the weak point of existing vulcanizer Type B central authority, the purpose of this utility model provides a kind of capsule apparatus that changes of changing capsule time weak point and reliable sealing tire forming vulcanizer central authority.
Can realize above-mentioned purpose the tire forming vulcanizer central authority change capsule apparatus, comprise capsule chuck down, ring seat and will play the coaxial clamping device of fixedlying connected of capsule chuck and ring seat, different is that described clamping device comprises pull bar, adapter sleeve and nut, adapter sleeve is axially fixed at the ring seat bottom, offer through hole corresponding to the adapter sleeve position on the ring seat, pull bar passes ring seat through hole and adapter sleeve, tie rod end T-shape head enters down in the T-shape groove of offering capsule chuck bottom in the ring seat top, and pull bar tailing screw flight section is the attaching nut outside the adapter sleeve bottom.
Be with the pull bar half-twist during use, tie rod end T-shape head is bitten the T-shape groove, fastening nut makes pull bar hold down, and the capsule chuck is pressed on the ring seat, this pulling force can not guarantee that the sealing of central authority gets final product under the pressure situation in having, and in sulfidation, under the effect of pressing in sulfuration, pressed sealing device makes sealing more reliable to following capsule chuck with the ring seat applying more; Unclamp nut and make 90 ° of pull bar reverse rotations, tie rod end T-shape head loosens the T-shape groove, and following capsule chuck separates with ring seat at once.
For the pull bar half-twist is accurately located, can on the pull bar in adapter sleeve radially spacer pin be set, the spacer pin termination is stretched in 90 ° of arc grooves offering on the adapter sleeve jacket wall, and 90 ° of arc groove restriction pull bars rotate in positive and negative 90 °.
Be handled easily, also be provided with pull bar is made progress spring mechanism that stressed maintenance suspends in the adapter sleeve, tie rod end T-shape head is in the T-shape groove of capsule chuck down all the time.
A kind of form of described spring mechanism comprises spring and end cap, and end cap is located at the adapter sleeve bottom, and pressure mounting of the spring is between the pull bar shaft shoulder and end cap of spacer pin below.
Stressed everywhere even for making, described clamping device is many groups, and evenly is provided with around the axle center.
Advantage of the present utility model:
Because changed the connected mode of ring seat with following capsule chuck, the torsional deformation of capsule can not have influence on the sealing of ring seat and following capsule chuck, and saves the connect hours of ring seat and following capsule chuck, has finally improved the operating efficiency of vulcanizer.
(4) description of drawings:
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1 embodiment.
Fig. 3 is the structural representation of following capsule chuck in Fig. 1 embodiment.
The figure number sign:
1, nut; 2, end cap; 3, adapter sleeve; 4, spring; 5, spacer pin; 6, pull bar; 7, following capsule chuck; 8, ring seat.
(5) specific embodiment:
The utility model relates in the tire forming vulcanizer central authority clamping mode that is connected of capsule chuck 7 and ring seat 8 down, as shown in Figure 1, and following capsule chuck 7 coaxial being seated on the ring seat 8, and by equally distributed many group clamping devices and ring seat 8 clampings around the axle center.
Every group of clamping device comprises pull bar 6, adapter sleeve 3, end cap 2, nut 1, spring 4 and spacer pin 5, adapter sleeve 3 is fixed in ring seat 8 flange ends bottom, offer axially extending bore at ring seat 8 flange ends corresponding to adapter sleeve 3, pull bar 6 passes ring seat 8 flange end through holes and adapter sleeve 3, the tail end thread segment of pull bar 6 is stretched outside adapter sleeve 3 bottoms, the tail end that end cap 2 passes pull bar 6 is connected with adapter sleeve 3 bottoms by screw thread, as shown in Figure 1.
Offer two relative 90 ° of arc grooves on the jacket wall of adapter sleeve 3 inner and upper, on the pull bar 6 corresponding with the arc groove radially spacer pin 5 is set, the two ends of spacer pin 5 lay respectively in the relative arc groove, with rotating with inhour clockwise of 90 ° on restriction pull bar; On the pull bar 6 of spacer pin 5 belows the shaft shoulder is set, be pressed with spring 4 on the pull bar 6 between the shaft shoulder and the end cap 2, because the support of spring 4 makes pull bar 6 be in suspended state, the end T-shape head height of pull bar 6 goes out the flange end of ring seat 8, its position just in time can enter down in the T-shape groove of offering capsule chuck 7 bottoms, as Fig. 1, Fig. 2, shown in Figure 3.
As shown in Figure 1 and Figure 2, nut 1 is screwed on the screw thread of pull bar 6 tail ends, forces tight end cap 2 tension pull bars 6 when nut 1 is tightened.
