Description

Technical Field

[0001] The utility model relates to the technical field of bladder vulcanizing machines, in particular to a side swing arm type hydraulic cylinder pressing device for a bladder vulcanizing machine. Background Art

[0002] A bladder vulcanizer, which uses a molding method to manufacture bladders for tire shaping vulcanizers, is primarily composed of a main cylinder, an upper core mold cylinder, a lower core mold cylinder, an upper crossbeam, wall panels, and an oil system. Chinese patent publication number CN104057562B discloses a hydraulic three-layer vulcanizer comprising two spaced-apart columns, a tie rod, and a bladder. An upper crossbeam is positioned between the tops of the two columns, and a lower crossbeam is positioned between the bottoms of the two columns. A mold opening and closing cylinder is positioned in the upper crossbeam. A die pressing mechanism, an upper vulcanizing mechanism, a middle vulcanizing mechanism, and a lower vulcanizing mechanism are positioned sequentially between the two columns, from top to bottom.

[0003] Regarding this disclosed technology, generally, multi-layer bladder vulcanizers require greater pressure to shape the tire after mold closing in actual production. Currently, the product equipment on the market mainly installs a hydraulic cylinder on the crossbeam on the upper part of the main frame. The piston rod of the hydraulic cylinder passes through the crossbeam and applies downward pressure. Since the hydraulic cylinder is installed on the crossbeam on the upper part of the main frame, the overall height of the vulcanizer is relatively high. The higher the height of the vulcanizer, the higher the height requirement for the production workshop in actual production, which increases the initial investment cost of the factory. In addition, some factory buildings are built in the early stage, and the roof of the factory building needs to be rebuilt to adapt to the height of the vulcanizer.

[0004] For this purpose, a side swing arm type hydraulic cylinder pressing device for a bladder vulcanizing machine is proposed. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that a general multi-layer bladder vulcanizer requires a large pressure for shaping the tire after mold closing in actual production. The product equipment currently on the market is mainly arranged by arranging a hydraulic cylinder on the crossbeam on the upper part of the main frame, which makes the overall height of the vulcanizer higher. The higher the height of the vulcanizer, the higher the height requirement for the production workshop in actual production. The utility model provides a side swing arm type hydraulic cylinder pressing device for the bladder vulcanizer.

[0006] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0007] The top surface of the hydraulic cylinder is fixed with a hydraulic cylinder to move upwards, and the hydraulic cylinder is connected with the hydraulic cylinder to move upwards, so that the hydraulic cylinder can move upwards and downwards.

[0008] Furthermore, the flip assembly includes a rotating shaft seat, the surface of the mounting steel plate is fixedly connected to the rotating shaft seat by bolts, the inner wall of the rotating shaft seat is movably connected with a rotating shaft, and a clamping block is arranged on the surface of the rotating shaft, and the plum blossom coupling is connected to the rotating shaft, and the top surface of the rotating shaft is fixedly connected to a limiting block.

[0009] Furthermore, the auxiliary component includes a sleeve, the surface of the swing arm is fixedly connected to the sleeve, and the rotating shaft is connected to the sleeve, the inner wall of the sleeve is provided with a slot, and the clamping block is plugged into the slot, the surface of the auxiliary component is fixedly connected to the sleeve, and the hydraulic cylinder pipe mouth is opened on the surface of the sleeve, and the threaded hole is opened on the surface of the sleeve, and multiple threaded holes are distributed in a circular array on the surface of the sleeve.

[0010] Furthermore, the drive assembly includes a mounting seat, the surface of the column is fixedly connected to the mounting seat, the top surface of the mounting seat is fixedly connected to the reduction motor, and the plum blossom coupling is connected to the output end of the reduction motor.

[0011] Furthermore, the clamping assembly includes a fixed sleeve, the inner wall of the sleeve is movably connected to the fixed sleeve, the groove is opened on the surface of the fixed sleeve, and the second hydraulic cylinder pipe mouth is opened through the surface of the fixed sleeve, and the top surface of the fixed sleeve is fixedly connected to the hydraulic cylinder through a nut.

[0012] Furthermore, the limiting assembly includes a top block, the bottom surface of the inner wall of the upper crossbeam is fixedly connected with the top block, and the bottom surface of the top block is fixedly connected with an arc-shaped stopper.

[0013] The beneficial effects of the utility model are as follows:

[0014] The utility model is used for the installation of the clamping assembly, and the swing arm is installed on the flip assembly through the parts of the auxiliary assembly when the mold is needed. The clamping block is set on the surface of the rotating shaft. After the sleeve is sleeved on the surface of the rotating shaft, the clamping block is inserted into the clamping groove. Then, when the rotating shaft rotates, the sleeve can be driven to rotate, and then the swing arm can be driven to swing. The sleeve is used for the installation of the clamping assembly. The interior of the fixed sleeve is opened through the groove. Since the groove is elliptical, when the swing arm moves the hydraulic cylinder to the mold closing position, a small gap is provided between the top of the hydraulic cylinder and the limit assembly. When the hydraulic cylinder telescopic rod applies pressure downward, the hydraulic cylinder is pushed by the upward reaction force. Move upward along the groove in the sleeve to make the top of the hydraulic cylinder contact with the top surface of the limit assembly. The drive assembly is set to drive the swing arm to swing. When the swing arm swings, the switch column of the solenoid valve monitors and controls the swing process of the swing arm. The limit assembly is set, and the arc stopper can be used to limit the rotation position of the hydraulic cylinder. The device fixes the clamping assembly to the column on one side, and moves the clamping assembly to the lower part of the upper beam and the upper part of the die structure by rotating the swing arm, thereby completing the downward pressing. This not only completes the downward pressing, but also reduces the overall height of the vulcanizer, thereby reducing the height requirement for the production workshop.
