Abstract
The utility model discloses a radial contracting drum for solid tyres, which comprises a drum surface which has a split structure; the inner side of each piece of the drum surface is provided with a connecting rod which is fixed on the drum surface by a rotating shaft; a mobile air cylinder is fixed at the other end of the connecting rod by the rotating shaft and provided with a bidirectional-extension fixed piston in the center; a left air chamber and a right air chamber are respectively formed between the inner side of the mobile air cylinder and the bidirectional-extension fixed piston; an expansion air inlet is arranged at the left end of the bidirectional-extension fixed piston and communicated with the left air chamber; and a contracting air inlet is arranged at the right end of the bidirectional-extension fixed piston and communicated with the right air chamber. By adopting the movable drum surface structure, the drum surface can expand and contract radially with the expanding and contracting range reaching 130 percent to 150 percent so as to meet the production requirements of tyres with different dimensions, thus reducing the frequency of replacing drums for producing tyres with different specifications for production workers, reducing labour intensity of work and improving the production efficiency as well. The radial contracting drum has simple structure, easy manufacture and good use effect.
Description
Technical field
The utility model relates to a kind of tire assembly drum, especially a kind of solid tyre radial contraction drum.
Background technology
At present, tire assembly drum is an important device in the tire production, tire assembly drum is generally speaking according to the tire size difference of being produced, need corresponding different model specifications, the diameter of conventional tire assembly drum has 105% to 115% telescopic variation scope, but such telescopic variation scope is difficult to satisfy the tire size variation of production plurality of specifications, and stretch mode complexity, generally on same board, need change different big or small tire assembly drums by the tire of production and processing different model, increase working strength of workers so greatly, and influenced production efficiency.
The utility model content:
The purpose of this utility model is: a kind of solid tyre radial contraction drum is provided, it can change the radial dimension of assembly drum, do not need the re-type assembly drum just can be fit to the tire size of production plurality of specifications, and stretch mode is simple, to overcome the deficiencies in the prior art.
The utility model is achieved in that solid tyre radial contraction drum, comprise bulging face, the drum face is a splitted structure, all be provided with the connecting rod that is fixed on by rotating shaft on the bulging face in the inboard of every lobe drum face, the other end at connecting rod is fixed with mobile cylinder by rotating shaft, be provided with two fixed pistons of stretching at the center of mobile cylinder, the inboard of mobile cylinder and two stretching have constituted left air chamber and right air chamber respectively between the fixed piston, be provided with the expansion air inlet at two left ends of stretching fixed piston, the expansion air inlet is communicated with left air chamber, be provided with the contraction air inlet at two right-hand members of stretching fixed piston, shrink air inlet and be communicated with right air chamber.
All be provided with lead in every lobe drum face inboard, the fairlead of lead is fixed on two stretching on the fixed piston.
Be provided with mounting flange at two left ends of stretching fixed piston.
Owing to adopted technique scheme, compared with prior art, the utility model adopts a kind of drum face structure of activity, and bulging face can be stretched diametrically, and flexible scope can reach
130%～150%, to satisfy the tire production demand of different size, reduced the direct labor and must change bulging frequency in order to change the production different types of tyre, reduce the labour intensity of work, and improved production efficiency.Of the present utility model simple in structure, make easily, and result of use is good.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is a use schematic diagram of the present utility model
The specific embodiment
Embodiment of the present utility model: the structure of solid tyre radial contraction drum as shown in Figure 1, produce the bulging face 1 of splitted structure earlier, inboard at every lobe drum face 1 all fixedly mounts two rotating shafts, a connecting rod 2 all is installed in each rotating shaft, and the other end of connecting rod 2 is fixed on the mobile cylinder of making in advance 3 by rotating shaft; Two fixed piston 4 of stretching is installed in mobile cylinder 3 in the heart, and on two contact-making surfaces of stretching fixed piston 4 and mobile cylinder 3, all install seal 12, make the inboard and two the stretching of mobile cylinder 3 form left air chamber 5 and right air chamber 6 between the fixed piston 4, offer an expansion air inlet 7 at two left ends of stretching fixed piston 4, expansion air inlet 7 is communicated with left air chamber 5, and at two ring flanges 11 of left end welding of stretching fixed piston 4; Be provided with contraction air inlet 8 at two right-hand members of stretching fixed piston 4, shrink air inlet 8 and be communicated with right air chamber 6; And two leads 9 all are installed in the inboard of every lobe drum face 1, the fairlead 10 of every lead 9 all is fixed on two stretching on the fixed piston 4.
In use, when needs are expanded drum face 1, two expansion air inlet 7 terminations of stretching fixed piston 4 are connected compressed air hose, air is transported to the left air chamber 5 from expansion air inlet 7, mobile cylinder 3 is moved to the left by air push, an end that so just makes connecting rod 2 be fixed on mobile cylinder 3 is moved to the left, and an end that is fixed on the bulging face 1 outwards ejects, and realizes the expansion of drum face 1; When needs shrink drum face 1, the termination of shrinking air inlet 8 is connected upward compressed air hose, air is transported to the right air chamber 6 from shrinking air inlet pipe 8, mobile cylinder 3 is moved right by air push, an end that makes connecting rod 2 be fixed on mobile cylinder 3 moves right, connecting rod 2 is fixed on an end of bulging face 1 and then regains to the inside, up to getting back to original position, so just realizes the contraction of drum face 1; In the expansion or the process of shrinking, two fixed pistons 4 of stretching do not move, by mobile cylinder 3 in two side-to-side movements of stretching on the fixed piston 4, thereby drivening rod 2 motions, to realize the expansion or the contraction of drum face 1; Lead 9 makes the bulging face 1 can move left and right in radial dilatation or when shrinking; And ring flange 11 can make things convenient for device installing and fixing in actual production.
