Rubber and tire fields

The rubber and tire industry is a very important heavy industry application scenario for its mechanical blades and cutting tools products. Due to the high elasticity, toughness, high viscosity, and susceptibility to heat during shearing of rubber itself, as well as the presence of composite interlayers such as steel wires and fibers inside tire manufacturing, the industry has almost stringent requirements for the wear resistance, impact resistance, and sharpness of blades. The following is an introduction to typical application scenarios of Henglida's related products in the industry: 1. Tool application in the entire tire manufacturing process (Tyre Manufacturing). A tire needs to go through multiple cutting and segmentation processes from raw materials to finished products, and high-precision tools directly determine the dimensional accuracy of semi-finished products and the dynamic balance performance of the final tire. Rubber Slitting&Strip Cutting: Application scenario: After producing a wide width mixed film through mixing and calendering, it is necessary to longitudinally cut it into specific width rubber strips or tapes. Use of cutting tools: rubber slitting disc knife, pneumatic slitting knife, flying knife. Pain points in the scene: The adhesive material is prone to sticking to the knife, and high-speed cutting is prone to heating. High quality blades need to have extremely high sharpness and be coated with anti sticking properties. Cord Fabric Cutting: Application scenario: The skeleton materials of tires (steel cord fabric, fiber cord fabric) need to be precisely cut at specific angles (such as 90 ° or diagonal). Use of cutting tools: steel cord cutting knife (usually a large disc knife or long scissors), fiber cutting knife. Scenario pain points: The steel wire curtain has extremely high hardness, and ordinary blades are prone to breakage or rapid wear. The blade must be made of high alloy die steel (such as Cr12MoV, W6Mo5Cr4V2, etc.) or hard alloy (tungsten steel) to ensure high impact resistance and long service life. Tread&Sidewall Cutting: Application scenario: After the continuous tread is extruded by the extruder, it needs to be cut to a fixed length according to the unfolded length of a single tire (usually using thermal cutting or ultrasonic cutting combined with mechanical structure). Use of cutting tools: tread cutting knife, irregular tooth shaped knife, cutting whole knife. Building&Trimming: Application scenario: During the green tire molding stage or after vulcanization molding, excess rubber edges and bristles (rubber strips generated by exhaust holes) need to be removed from the tire. Use of cutting tools: pneumatic trimming knife, micro trimming round knife, handheld/robotic arm trimming knife. 2、 In addition to tires, in the production of conveyor belts, seals, various types of rubber hoses, and the recycling of waste rubber, cutting tools are also core consumables in the general rubber products and recycled rubber industry. Waste Rubber Shredding: Application scenarios: The recycling and reuse of waste tires (waste wheel hubs, waste rubber) is an important link in environmental protection and resource recycling. Hard and steel wire containing waste tires need to be crushed as a whole. Tools used: Strong shredder blades (multi claw blades, square blades), tire crusher blades, heavy-duty capacity reducing blades. Pain point of the scene: It needs to withstand extremely high torque and forced cutting of steel wires. The blades are mostly made of heavy-duty high toughness alloy steel and undergo deep heat treatment, with extremely strong anti fracture performance. Conveyor Belt&V-Belt Cutting: Application scenarios: slitting and cutting of industrial conveyor belts and transmission belts before and after molding. Use of cutting tools: irregular tooth shaped flat element knife, strip shaped cutting knife, and slitting round knife. 3、 Henglida's tool technology characteristics in the rubber tire industry. In order to address the three major challenges of "hardness, stickiness, and toughness" in rubber tire processing, professional manufacturers such as Henglida usually provide the following targeted solutions: core dimension solutions and technical applications. Strict material selection includes 9CrSi, Cr12MoV (D2), W6Mo5Cr4V2 (M2 high-speed steel), and hard alloys (tungsten steel). Balancing hardness (wear resistance) and toughness (anti chipping). Customized rubber machinery often uses non-standard and irregular cutting tools (such as special toothed knives and curved bar knives). The manufacturer relies on precision grinding machines and five axis machining centers to achieve high-precision non-standard customization. The special treatment of the cutting edge adopts mirror polishing technology to reduce the roughness of the cutting edge, or special surface spraying (such as anti friction coating) is carried out to effectively reduce the rubber sticking resistance and lower the
