Abstract

The invention discloses a trimming device for seal rings on a wagon braking system. The trimming device is characterized by comprising a seal ring fixing device (2), trimming device bodies (4), a connecting device (6), a limiting device (7), a first driving device and a second driving device (9). Provided with the seal ring fixing device (2) and the trimming device bodies (4), the trimming device is capable of automatically trimming through rotation of the first driving device, but a difficulty lies in positioning between the seal ring fixing device (2) and the trimming device bodies (4). The trimming device for the seal rings on the wagon braking system has the advantage that the difficulty in positioning between the seal ring fixing device (2) and the trimming device bodies (4) is overcome with the help of a linear light emitter (16) and a light receiving panel (14), so that a trimming effect is further improved.

Description

technical field [0001] The invention relates to an edge trimming device for a sealing ring on a railway freight car braking system. Background technique [0002] After the vulcanization process is completed, the E-shaped sealing ring used in the brake system of railway freight cars will have more or less rubber edges on the parting surface of the mold, and it needs to be polished and trimmed to obtain qualified products. [0003] In the current production process, the trimming method usually used is manual trimming or trimming with a liquid oxygen freezing trimming machine. When trimming manually, the efficiency is low, and the product is easily damaged by cutting, resulting in defective products and affecting the overall quality of the product; the use of liquid oxygen freezing and trimming will cause a large amount of abrasive particles to remain in the gap between the E-rings, which is extremely difficult and time-consuming to remove It is laborious and cannot meet the r...
