Description

Technical Field

[0001] The invention belongs to the technical field of tire production, in particular to a tire embryo puncturing machine for engineering machinery tires. Background Art

[0002] The molding process of modern engineering machinery tires relies on high-precision mechanical equipment and advanced automation technology. It uses an automated tire blank molding machine, which can accurately combine rubber materials, cords and other components according to design requirements. Through computer-controlled robotic arms and precise molds, the accuracy of the size and shape of each part of the tire is ensured, and the quality of the tire blank is improved. Vulcanization is a key link in the tire manufacturing process, which determines the physical properties of the tire rubber. The advanced vulcanization process uses more precise temperature, pressure and time control, which can better cross-link the rubber molecules.

[0003] When puncturing the embryo of an engineering machinery tire, the existing embryo puncturing machine generally places the embryo of the tire directly on the surface of a roller, and then rotates the embryo of the tire by rotating the roller, while the needle slides up and down repeatedly to puncture the embryo of the tire. However, the rotation of the roller easily causes wrinkles on the surface of the embryo of the tire, so that the puncture position may deviate when puncturing, and the puncture position accuracy required by the design cannot be achieved. The wrinkles may also cause uneven puncture depth on the surface of the embryo, so that the needle may not be able to puncture according to the preset depth, thereby causing instability in the puncture of the device.
