Description

Technical Field

[0001] The utility model relates to the technical field of rubber piece processing, in particular to a special trimming device for rubber sealing pieces. Background Art

[0002] Rubber seals are a common, basic component in sealing devices, playing a crucial role in resolving the conflict between leakage and sealing. Solving these problems has consistently driven technological advancement in humanity's conquest of nature and is a crucial approach to preventing and reducing environmental pollution. Furthermore, rubber seals are a widely used type of rubber product in sealing technology. Rubber is a valuable elastic polymer material with a wide temperature range. It deforms significantly when subjected to minimal stress in different media. This deformation provides contact pressure, compensating for leakage gaps, and achieving sealing. Currently, major rubber products include rubber sealing rings, rubber gaskets, flange gaskets, and rubber shock absorbers. After rubber seals are manufactured, burrs may remain on the edges of the molded seals, affecting the sealing effect.

[0003] After searching, China disclosed a special trimming device for rubber seals with patent publication number CN215702227U on February 1, 2022. It is roughly described as including a workbench with a support frame provided on the upper surface; a controller for controlling the operation of the device; a rotating table rotatably arranged on the workbench and driven by a first motor; a clamp arranged on the rotating table for fixing the seal; a cutting mechanism arranged above the clamp with an adjustable angle for processing the seal; wherein the cutting mechanism includes a fixed seat, a turning table, a drive assembly and a cutter, the fixed seat is arranged under the support frame, the turning table is turnably arranged under the fixed seat, the drive assembly is arranged on the turning table for driving the turning table to turn over, and the cutter is rotatably arranged on the tool holder below the turning table and driven by a second motor.
