Abstract

The invention discloses an edge trimmer, which is used to trim sealing members. The edge trimmer comprises a body; a clamp, which is arranged on the body and comprises a support connected to the body and a clamping part capable of rotating relative to the support, wherein the clamping part clamps and fixes a sealing part; a trimming member, which abut against the clamp, is correspond to the burr of the sealing ring of the sealing member, and is tightly attached to the burr of the sealing member; and a power device, which drives the clamping part to move the burr of the sealing part relative to the trimming member. The edge trimmer basically achieves the automatic trimming, especially for the soft rubber sealing members, and solves the problem that soft rubber sealing members are hard to fix. The trimming speed of the edge trimmer is fast, the efficiency is high, and thus labor cost is reduced.

Description

technical field [0001] The invention relates to a grinding and polishing equipment, in particular to a trimming machine. Background technique [0002] In the production process of rubber products, in order to prevent the lack of glue, the rubber filled in the mold cavity will maintain a certain excess. At the stage of molding vulcanization, the rubber will quickly fill the mold cavity, and the excess rubber will pass through the mold parting surface or The joint with the metal inlay overflows to form burrs. Once the burrs are formed, they must be trimmed to get a good product, so that the product has a neat and beautiful appearance. [0003] At present, manual trimming is mostly used, that is, the operator holds a knife and gradually removes the flash along the outer and / or inner edges of the product. Especially for relatively soft rubber parts, it is difficult to fix them well through mechanical structures, and then quickly trim them. However, the manual trimming method i...
