Description

Opposite-jacking type forming device and forming method

Technical Field

The invention relates to the technical field of forming processes, in particular to an opposite-top forming device and a forming method.

Background

The layout of the traditional forming device is shown in fig. 1, a main machine feeding frame and an auxiliary machine feeding frame are arranged on the same side of a front guide rail from left to right, and an operator walks for about 5.5 meters to a point B to attach a belt ply after completing the attachment of a tire body cylinder at the position A. The tire building machine production process is divided into 3 major stages. The method comprises the following steps: the process of fitting the carcass composite, the process of fitting the belt and tread composite and the process of forming (shaping and rolling after the carcass composite and the belt and tread composite are compounded). The 3 stations can be produced independently and simultaneously. The process of applying the carcass composite and the process of applying the tread composite generally require manual operations by operators, depending on the raw materials, the tire production process, and the like. And the center distance between the tire body attaching station and the belt and tread attaching station of the traditional forming machine exceeds 5.5 meters (the distance from A to B in figure 1 exceeds 5.5 meters), because the attaching of the tire body composite part and the attaching of the belt and tread composite part are completely independent and carry out the production process simultaneously, an operator: or shuttle back between station a and station B for production (1 single operator molding machine), or two operators for production per molding machine. The production cycle of a single heavy-duty tyre is approximately between 180 and 200 seconds, the performance of the equipment is sacrificed if the single operator moves back and forth for 5.5 meters, and the operator increases the great load (600 tyres per day, the distance of the back and forth exceeds 6600 meters), and the safety risk of the operator is also increased. Therefore, most tire plants are produced by two operators per building machine.

There is also a problem with conventional molding machine apparatus: frequent reloading and affects production efficiency. After the materials are used up, the empty trolley is required to be unloaded, the trolley full of the materials is loaded, and the head of the materials is required to be treated; in most cases, the equipment is stopped to wait for the completion of refueling and then the production is continued. The method is obtained by counting the material changing frequency and the material changing time of each time: each molding machine lost greater than 13.8% of direct downtime due to changeover daily under normal production conditions. The yield loss caused by the speed reduction production, the production rhythm change and the like caused by material change is not included.

moving the tire body cylinder transfer ring from the middle waiting position to the position of the vertical center of the main machine feeding frame, and taking away the tire body cylinder composite part to the tire body cylinder transfer ring;

the tire body cylinder transfer ring moves from the vertical center position of the main machine feeding frame to the vertical center position of the back press roller to transfer the tire body cylinder composite to the machine box position of the forming drum.

In one embodiment, in step two, the carcass tube composite is moved vertically by the building drum machine box to the belt transfer ring horizontal position, waiting for the tread, the composite of the first belt, the second belt, the third belt and the fourth belt.

In one embodiment, in step three,

In one embodiment, in step five, the building drum chassis is moved up to the rear back press roll for rolling, the building drum chassis is moved up to the tire unloader station for tire unloading, and the tire unloader performs tire unloading.

The technical scheme provided by the embodiment of the invention has the following beneficial effects:

firstly, the forming machine is rearranged, the tire body fitting station and the belted tire surface fitting station are arranged in an opposite-jacking mode, and after the forming station is arranged on the side face, the center distance (from a point A 'to a point B') between the forming fitting station and the belted tire surface fitting station is greatly reduced, so that the distance between the forming fitting station and the belted tire surface fitting station is smaller than 1 m. An operator can move from a tire body fitting station to a belted tread fitting station only by moving within 1 meter, and a traditional forming machine needs to move by about 5.5 meters. After the operator finishes the tire body cylinder fitting, the operator turns around (from the point A 'to the point B') to fit the belt layer, so that the walking distance of the operator is effectively reduced, and the production time loss caused in the moving process is reduced.

Secondly, the forming machines are arranged in a butt-top mode, a group of standby feeding frames can be installed between the two forming machines, and the standby feeding frames load the same production raw materials as the two forming machines. And then the front guide rail part moving machine bases of the two forming machines and the machine base of the standby feeding frame are connected into a whole through mechanical structures such as linear guide rails, so that the forming drum machine boxes and the belt drum machine boxes of the two forming machines can move on the machine base along the direction vertical to the direction of the feeding frame along the machine base direction. Make two sets of building drum machine casees can remove reserve pad and glue the feed frame, reserve ladle feed frame and reserve matrix feed frame below, make two sets of belted drum machine casees can remove reserve belted feed frame and reserve tread feed frame below. When one material of one forming machine is used up, the forming drum machine box or the belt drum machine box can be moved to the lower part of the standby supply frame for laminating production. When the forming machine is used for producing under the standby feeding frame, an operator can replace used materials, so that the forming machine can continue to produce without stopping when the operator replaces the materials. The cost of the standby feeding frame is about 18 percent of that of a single forming machine, and the direct benefit of the non-stop material changing of the two forming machines is that the cost of the standby feeding frame is improved by more than 27.6 percent of that of the single forming machine. And because the traditional forming machine is stopped when changing materials, the productivity is affected, so the tire factory requires timely changing materials in order to reduce the loss, namely, a material changing operator takes place in advance to wait for the equipment to change materials immediately after the materials are used up. This would result in a significant amount of personnel waste. The application of the invention can avoid the problems, thereby reducing the number of operators for changing materials in the tire factory.

Third, the effect on throughput by the actual number of reloads to the top forming apparatus is shown in the following table:

note: each machine was operated for 3 shifts, and each shift was operated for 7.5 hours

At the moment, the composite part of the inner liner of the tire sidewall, the tire body, the steel wire rabbet wrapping cloth and the cushion rubber are wrapped and bonded on the tire body drum to form a tire body cylinder composite part. The carcass drum transfer ring 3 is moved to the right in the direction perpendicular to the feeding direction to the centre of the carcass drum, picking up the carcass drum composite in the carcass drum transfer ring. The transfer ring of the carcass tube is moved leftwards in the direction perpendicular to the feeding direction, and at the same time the machine box 4 of the shaping drum carries the shaping drum to move rightwards in the direction perpendicular to the feeding direction, so that the shaping drum penetrates through the transfer ring of the carcass tube, and the composite part of the carcass tube is arranged in the center of the shaping drum. The building drum is expanded to attach the carcass tube composite to the building drum.
