Description

The mechanical anti-package device of building machine for engineering tire

Technical field

The utility model belongs to the rubber tyre forming machine, relates to the improvement of building machine for engineering tire, particularly a kind of improvement of building machine for engineering tire anti-package device.

Background technology

At present, existing building machine for engineering tire adopts inflatable glue to assist anti-package or workman manually directly to carry out reverse wrap molding mostly; Adopt inflatable glue to assist anti-package, need a whole set of turn-up and turn-down device, expense is higher, and it is in the carcass forming process, need assist interior inflated compressed air to glue, after making glue assist expansion, also need independent metal structure throw-out collar compressing glue to assist distortion, finish position, sidewall anti-package and compacting operation, after finishing this operation, also need to assist interior gas to give off in glue, glue is assisted return to original state, just can carry out the operation of the next item down operations for forming; The time of the required waits of operation such as this inflation, venting, throw-out collar compacting is longer; And anti-package operation manually, working strength is bigger on the one hand, and uniformity is not fine, can bring harmful effect to the inherent quality of green tyres moulding.

Technology contents

In order to overcome the deficiency that existing building machine for engineering tire glue is assisted wasting time and energy of anti-package and manual anti-package and influenced tire blank molding quality, the utility model provides a kind of mechanical anti-package device of building machine for engineering tire.

The technical solution of the utility model is: a kind of mechanical anti-package device of building machine for engineering tire, this device includes synchronous ring, crank, anti-package ring, anti-package pawl, slide block folder, the anti-package ring is provided with radial groove, be milled with axial elongated slot on the chute, by the slide block folder anti-package pawl slide block is fixed in the radial groove of anti-package ring, the anti-package ring that has the anti-package pawl is fixed on the synchronous ring, is milled with oblique elongated slot on the synchronous ring; Crank in this device comprise pivot pin and be nested with on pivot pin two the joint sliding sleeves, two the joint sliding sleeves in the elongated slot of synchronous ring and anti-package ring, slides respectively, crank is connected with anti-package pawl slide block; Described anti-package pawl comprises button pawl and slide block, and button pawl and slide block constitute a T font, and its button pawl is that recessed another side protrudes on one side, and projection just in time inserts another recessed position of piece button pawl, forms a button circle.

The beneficial effects of the utility model are:

1, the controllability of anti-package loop diameter: the size of promptly stepless within the specific limits synchronous adjustment anti-package loop diameter;

2, the automaticity of anti-package loop diameter adjusting: promptly aspect change anti-package circle bore way, the mechanism of being gone up design by this device adjusts to the right place automatically;

3, reduce labor intensity, increase work efficiency: after the support greatly of casing ply circle mouth diameter, only with hand stoops it just gently during anti-package;

4, improved Forming Quality: owing to adopt mechanical anti-package, stressed even, help Forming Quality.

The utility model will be further described below in conjunction with the drawings and specific embodiments.

The specific embodiment

This device is a kind of intermediate link device of novel building machine for engineering tire, and this device comprises cylinder 1, crank 2, synchronous ring 3, anti-package ring 4, anti-package pawl 5 as shown in Figure 1, and the anti-package ring 4 that has anti-package pawl 5 is fixed on the synchronous ring 3; Anti-package pawl 5 comprises button pawl 32 and slide block 31 as shown in Figure 3, Figure 4, and button pawl 32 constitutes a T font with slide block 31, and its button pawl is that recessed another side protrudes on one side, and projection just in time inserts another recessed position of piece button pawl, forms a button circle; Anti-package ring 4 shown in Figure 5 is provided with radial groove 51, axial elongated slot 52, and synchronous ring 3 shown in Figure 6 is provided with oblique elongated slot 61; Anti-package pawl 5 is fixed on anti-package pawl slide block 31 in the radial groove 51 of anti-package ring 4 by slide block folder 21 as shown in Figure 2;

Crank 2 in this device comprise pivot pin and be nested with on pivot pin two the joint sliding sleeves, two the joint sliding sleeves in the elongated slot of synchronous ring and anti-package ring, slides respectively, crank passes the oblique elongated slot 61 of synchronous ring and the axial elongated slot 52 of anti-package ring is connected with anti-package pawl slide block 31.

Synchronous ring 3 is driven by cylinder 1, synchronous ring 3 is rotated, the sliding sleeve that drives in the crank rotates, thereby crank 2 is rotated with sliding sleeve, driving anti-package pawl slide block 31 slides in the radial groove 51 of anti-package ring, its button circle circumcircle diameter of being made up of the button pawl becomes big, after the support greatly of casing ply circle mouth diameter, promotes sidewall infantees anti-package; Each sliding sleeve has same size and five equilibrium layout in this, make each sliding sleeve produce identical displacement in this way, thereby each crank 2 drives each anti-package pawl slide block 31 and produces identical radial displacement, make each slide block on same circumference, promptly realized the purpose of the automatic synchronous adjustable of anti-package by the utility model.
