Technical Field

[0001] The utility model relates to the technical field of production equipment of a radial passenger tire two-step molding machine, in particular to a tire blank clamp combination device. Background Art

[0002] The second stage forming machine of radial tire is used to expand and shape the first stage green tire of radial tire and to attach the belt layer, tread and other components. It is the machine to finally complete the green tire of radial tire. It is mainly composed of a machine box, a shaping machine head, a belt layer laminating machine, a transfer device, a rear pressure roller device, a belt layer feeding device, a tread feeding device and a control system.

[0003] In the traditional radial passenger tire secondary molding machine, the tire blanks are manually removed after one stage of molding, transported manually, and then put on the second stage molding machine. Traditionally, the tire blanks are unloaded by humans after one stage of molding, and then transported to the second stage shaping drum. This is not only inefficient, but also wastes manpower and material resources. For this reason, we proposed a tire blank clamp combination device. Utility Model Content

[0006] The tire blank is arranged on the side of the fixing frame, and the side of the tire blank is provided with a clamping assembly. Traditionally, a section of the tire blank is unloaded by a population and then transported to the second-stage shaping drum, which is not only inefficient but also wastes manpower and material resources. The tire blank clamp combination device of the utility model cooperates with a manipulator to efficiently transfer a section of the tire blank, which not only saves manpower and material resources but also has high efficiency. Most importantly, the tire blank clamp does not require manual adjustment of specifications, which can greatly improve production efficiency and adaptability to various specifications.

First, the tire blank clamp assembly device is transferred to a working position of a molding machine by a manipulator, wherein the cylinder with a clamping device and the ordinary small-stroke cylinder (stroke mm) piston rods in the series-connected combined cylinder are all extended, and the manipulator After detecting that it is in position, the ordinary small-stroke cylinder retracts its full stroke, the cylinder with the clamping device contracts to clamp a section of the tire blank, the locking cylinder is locked, and the stroke position of this clamping is recorded. Then the manipulator takes out a section of the tire blank and transfers it to the second-stage shaping drum. The clamping cylinder does not move, the piston rod of the small-stroke cylinder extends, the tire blank is released, and the transfer of a section of the tire blank is completed. The manipulator returns to the waiting position and enters the next round of clamping the tire blank cycle. When the specifications of the tire blanks are not changed in the next round of grabbing, only the ordinary small-stroke cylinder needs to be extended and retracted to complete the clamping of the next tire blank. No manual adjustment is required. The left and right clamping arms of the device are respectively fixed on the sliders of the left and right guide rails. One end of the cylinder is fixed on the guide rail frame fixing plate, and the other end is connected to the guide rail fixing plate as a fixed end. The cylinder piston rod is extended and retracted to drive the left clamping arm to move left and right. The rack fixed on the left clamping arm drives the meshing gear to rotate. The rotating meshing gear pushes the right rack to move. The right rack drives the right clamping arm to move symmetrically with the left clamping arm, realizing the synchronous and symmetrical opening and closing of the left and right clamping arms, thereby completing the clamping and loosening of the tire blank.

[0008] Preferably, the side wall of the clamping arm is fixedly connected to the side wall of the linear guide slider, and the inner wall of the linear guide slider is adapted to the outer wall of the fixed frame. Through this arrangement, the linear guide slider can slide on the outer wall of the fixed frame to realize the movement of the clamping arm, thereby achieving the purpose of clamping the tire blank.

The small stroke cylinder of the combined cylinder and the cylinder with the locking head are opened. The locking cylinder clamps the tire blank after an appropriate pressure (0.2-0.25MPa), and the locking head of the locking cylinder is locked. After the locking cylinder is locked, the stroke of the small stroke cylinder is used to achieve clamping and loosening, thereby realizing automatic specification adjustment of the clamping device; no manual adjustment is required;

At the same time, it is also safer than manual adjustment of specifications and improves the adaptability of various specifications. BRIEF DESCRIPTION OF THE DRAWINGS
