Abstract
The utility model belongs to the rubber machinery class and is mainly used for the molding of a tyre, and is a device which can be used in producing the tyre. The utility model is characterized in that a rotation sleeve in the central body of the utility model is rotated anticlockwise and clockwise. A drawing tray is driven to axially move, and various connecting rods drive a drum shoulder to fold and expand. While in working, the rotation sleeve (10) in the central body (4) is rotated, and a sliding pin (9) on the rotation sleeve (10) is driven to be slid along a chute on the drawing tray (8). A distance is an X, the drawing tray (8) axially moves to the X distance, and a small connecting rod (7), a triangular block (6), a middle connecting rod (5) and a large connecting rod (3) are driven to move. When the rotation sleeve (10) is rotated anticlockwise, the middle connecting rod (5) and the large connecting rod (3) move toward a shaft center direction to cause a large drum shoulder (1) and a small drum shoulder (2) to be folded and form a congruence state. When the rotation sleeve (10) is rotated clockwise, the middle connecting rod (5) and the large connecting rod (3) are far away from the shaft center direction to move, and the large drum shoulder (1) and the small drum shoulder (2) are spread and form a circular working condition.
Description
The utility model belongs to the rubber manufacturing machinery class, and being mainly used on the tire building is the device of producing the tire indispensability.
Various moulds (also the being head) kind of domestic various tire buildings is a lot of now.Generally design according to the lanar four rod mechanism principle.Precision is very low, and service life is short, watt phenomenon of collapsing often occurs, so that scraps.Big some head hundreds of thousands unit because the life-span is low, causes very big waste, therefore, must improve the head quality, and the design new construction improves precision, the service life of raising head.
The purpose of this utility model provides a kind of tire building requirement of satisfying, the precision height, and long service life, the former traditional lanar four rod mechanism principle design is designed to spoke and supports the formula tire shaping apparatus that directly contracts.This device has good stability, precision height, long service life, has eliminated watt phenomenon of collapsing.
The purpose of this utility model is to realize like this, the various connecting plates of the outside connection of centerbody on this tire shaping apparatus, in centerbody inside turning set is housed, fixing sliding pin is housed on turning set, be equipped with at centerbody one end and draw dish, big bar and small rod are housed drawing on the dish, the drum shoulder of these connecting rods and cylindrical is connected, when the turning set in the centerbody when being rotated counterclockwise, draw dish to move axially, the drive pull bar moves, and makes its drum shoulder become closed state as radial contraction; When the turning set in the centerbody when turning clockwise, draw dish to move axially, drive pull bar and move, making its drum take on to open becomes circular duty.
The utility model is compared with original plane four connecting rod heads, the project organization compactness, and material therefor is few, the precision height, good stability, the life-span is long, and is easy to operate.The life-span of new head is 2～3 times of old head life-span, calculates by general head, and a head is economized on the use of funds 10～200,000 yuan.
Concrete structure of the present utility model is provided by following examples and accompanying drawing.
Fig. 1 is the profile that supports the formula tire shaping apparatus that directly contracts according to the spoke that the utility model proposes.
This device is takeed on (2), big connecting rod (3), centerbody (4), middle connecting rod (5), corner block (6), small rod (7), is drawn dish (8), sliding pin (9), turning set (10), bearing pin (11) to form by big drum shoulder (1), side drum.
Following concrete apparatus structure and the working condition that proposes according to utility model that describe in detail in conjunction with Fig. 1.
This device is achieved in that when work turning set (10) rotates in centerbody (4), sliding pin (9) on the drive turning set (10) is along drawing dish (8) to move axially the distance into X, drive lower link bar (7), connecting rod (5) in the corner block (6), big connecting rod (3) moves.When turning set (10) when being rotated counterclockwise, middle connecting rod (5) big connecting rod (3) moves to axis direction, makes big drum shoulder (1) and side drum take on (2) and closes up, and is closed state.When turning set (10) when turning clockwise, middle connecting rod (5) big connecting rod (3) is to moving away from axis direction, big drum shoulder (1) and side drum are takeed on (2) and are opened and be the figure duty.
Claims (5)
1, spoke supports the formula tire device that directly contracts, and has centerbody (4) turning set (10) is arranged in centerbody (4); Corner block (6), small rod (7), middle connecting rod (5), big connecting rod (3) are arranged outward, draw dish (8), and skewed slot is arranged drawing on the dish (8), fixing sliding pin (9) is arranged on the turning set (10).
It is characterized in that: turning set is arranged in the centerbody, draws dish outward, when turning set rotates, drive and to draw dish to move axially, make this device superimposed with open.
2, device according to claim 1 has turning set (10) in centerbody (4), and on turning set (10) sliding pin (9) is housed, along drawing dish (8) skewed slot to slide.
3, device according to claim 1 draws dish (8) drive small rod (7), corner block (6), middle connecting rod (5), big connecting rod (3) to move.
4, device according to claim 1, the sliding pin (9) on the turning set (10) makes middle connecting rod (5), big connecting rod (3) move or move away from the axle center to the axle center along drawing the skewed slot on the dish (8) to slide.
5, device according to claim 1, middle connecting rod (5), big connecting rod (3) are takeed on (2), are drawn dish (3), centerbody (4) to be connected with big drum shoulder (1), side drum.
