Description

Technical Field

[0001] The invention relates to the technical field of rubber part cutting, in particular to a device for cutting automobile interior rubber parts. Background Art

[0002] Automotive interior rubber parts are soft, functional components made from natural rubber, synthetic rubber, or thermoplastic elastomers. They are primarily used for sealing, shock absorption, noise reduction, and decorative functions within the vehicle's cockpit and passenger compartment. Typical products include door seals, instrument panel gaskets, armrest hinges, wiring harness covers, and pedal anti-slip mats. These parts must be resistant to high and low temperatures, ageing, and have low volatility, ensuring environmental friendliness. They must also elastically deform to accommodate assembly tolerances and effectively block noise, dust, and moisture intrusion, playing a key role in improving vehicle NVH performance, ride comfort, and the durability of interior components.

[0003] During the production process of automotive interior rubber parts, the rubber is first produced into a whole rubber sheet, and then rubber strips are cut according to the size and shape of different products. The rubber strips are then placed in a mold for vulcanization production.

[0004] Existing rubber cutting equipment mostly uses strip cutters to cut rubber sheets in a straight line from top to bottom. The effect of straight line cutting is poor, and the rubber is prone to delamination or burrs at the cutting point, affecting the consistency of the finished product and may affect the production quality of automotive interior rafter rubber parts.
