Description
Technical field
The present invention relates to a kind of carcass assembly press fit device for preparing the carcass assembly for the manufacture of rubber tyre, belong to the rubber manufacturing machinery field.
Background technology
Being matched at present the rubber tyre of all kinds of vehicles, is mainly to adopt forming machine that wire bead, carcass assembly and belt-tread package are made fetus by techniques such as pressing, anti-packages.
In green tyres manufacturing process device, normally complete preparation carcass assembly on carcass drum, then with the carcass component transfer to assembly drum.In preparation carcass component process, both need adopt press fit device for the lap between inner liner and both sides sidewall rubber carry out stitching operation with extruding, discharge bubble, also need carry out stitching operation to the cord joint of follow-up winding.
Adopt the carcass assembly press fit device of prior art as shown in rear accompanying drawing 1, its scheme is that the composite members press fit device (50) that will successively implement stitching operation is installed separately with cord fabric stitching apparatus (60), and passes through the stitching operation of drive unit execution on carcass drum (70) separately.Wherein, composite members press fit device (50) is installed on support (51), and it drives cylinder (52) pressure roller (53) is delivered to pressing station on carcass drum (70) once from station is installed.
The major technique shortcomings and deficiencies part that prior carcass assembly press fit device exists is:
1, composite members press fit device (50) adopts separately independently installing mechanism with cord fabric stitching apparatus (60), need to be equipped with the driving cylinder (52) of larger stroke and driving force parameter, both to be unfavorable for the stability of composite members surface pressure closing operation, also to be unfavorable for reducing the cost of the driver part of purchasing;
2, be unfavorable for improving the initial installation accuracy of 2 Independent interposed structures, the degree of accuracy of successively implementing composite members, cord stitching operation is difficult to control;
3, composite members press fit device (50) and cord fabric stitching apparatus (60) adopt be installed separately, structure that each is self-driven, need the larger installing space of configuration and be unfavorable for the Miniaturization Design of complete machine structure;
4, many groups pressure roller of composite members press fit device (50) takes aligned type to arrange, and easily forms the gap of pressing between pressure roller and causes the bubble of subregion to discharge;
When 5, cord fabric stitching apparatus (60) operated, the recoil strength that causes due to stitching operation was easy to cause device to retreat greatly, thereby impact is for the pressing effect of cord joint.
In view of this spy proposes present patent application.
Summary of the invention
Carcass assembly press fit device of the present invention, its purpose is to solve the shortcoming that prior art exists and takes composite members press fit device and cord fabric stitching apparatus integrated installation in same balladeur train, with the initial installation accuracy that improves 2 Independent interposed structures and the Miniaturization Design of complete machine structure, thereby improve the degree of accuracy of successively implementing composite members, cord stitching operation.
Another purpose of design is, before the composite members stitching operation, the composite members press fit device is moved to the wait station in advance, reducing for the stroke that drives cylinder and the requirement of driving force parameter, thereby both improved the stability of composite members surface pressure closing operation, also be conducive to reduce the cost of the driver part of purchasing.
