Transmission arm mechanism used for press feeder

Abstract

The invention relates to a transmission arm mechanism used for a press feeder. The transmission arm mechanism comprises multiple stages of synchronous belt transmission systems, the synchronous belt transmission systems comprise synchronous belts, driving wheels and driven wheels, and the driving wheels drive the driven wheels through the synchronous belts; and the driven wheel of the previous stage of transmission system can be in transmission connection with the driving wheel of the next stage of transmission system through a rotating shaft. An original synchronous belt is divided into three parts, and meanwhile it is guaranteed that the synchronous belts can move along with the feeder in the tensioned state and are synchronous with a main shaft. By means of the structure, the action of adjusting die height to loosen and tension the synchronous belts each time can be omitted, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of presses, and in particular relates to a transmission arm mechanism for a feeder of a press. Background technique [0002] The feeder for the press needs to input power from the main shaft of the machine tool, and needs to rotate at the same speed as the main shaft. In the prior art, a synchronous pulley is generally placed from the main shaft, and the power is introduced to the synchronous pulley at the input end of the feeder through a synchronous belt. The synchronous belt uses a set of tensioning mechanism to tension the synchronous belt and play a steering role at the same time. The feeder for the press needs to adjust the height of the feeding surface according to the design parameters of different molds. When the feeder is raised and lowered, the timing belt needs to follow the rise and fall. Every time the feeder is raised and lowered, the timing belt must be loosened first, and then tensioned after the feed...

Problems solved by technology

The feeder for the press needs to adjust the height of the feeding surface according to the design parameters of different molds. When the feeder is raised and lowered, the timing belt needs to follow the rise and fall. Every time the feeder is raised and lowered, the timing belt must be loosened first, and then tensioned after the feeder is adjusted to the required height. Synchronous belt, frequent tension and relaxation of synchronous belt not only affects the service life of synchronous belt but also reduces production efficiency
