Description

TECHNICAL FIELD

[0002] Mechanical automation refers to the operation or control of machines or devices automatically according to predetermined programs or instructions without human intervention, and automation is realized through mechanical means. Through the automatic control system, not only large-scale industrial production is realized, but also labor intensity is significantly reduced and labor efficiency is improved. Today, various industries cannot do without automation systems.

[0003] The screw rod processing process includes rolling and pressing processes, and the rolling is used to roll the high-strength threaded steel with complex shape. At present, the operator manually takes the parts from the rack, puts them into the rolling machine or pressing machine for processing, and then manually takes them out for carrying after processing. This requires manual adjustment of the position of the screw rod on the conveyor belt, which is time-consuming and labor-intensive, and is prone to danger. If the material is not timely loaded and unloaded due to other reasons, the screw rod is prone to accumulate on the conveyor belt, causing the loading and unloading ports to be blocked, causing the screw rod to wear, affecting the precision of the rolling screw rod, and manual loading and unloading seriously affecting the processing efficiency. At the same time, manual operation is dangerous and prone to fatigue, which endangers personal safety.
