Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of numerical control machine tools, in particular to a high-precision numerical control feeder. BACKGROUND

[0002] In early industrial production, manual feeding is a common way. The operator relies on manpower to send raw materials (such as metal plates, bars or plastic profiles, etc.) into processing equipment (such as punch presses, cutting machines, etc.). This way is extremely low in efficiency, and the feeding accuracy completely depends on the experience and skills of the operator. For example, in the production of metal plate stamping, manual feeding is difficult to ensure the accuracy of the feeding position each time, resulting in difficulty in controlling the dimensional accuracy of the stamped parts and a high scrap rate; in modern industry, automation and intelligent manufacturing are the trend of development. On the automated production line, each device needs to be highly coordinated and accurately matched. As an important link in the production line, the high-precision numerical control feeder needs to be seamlessly connected with other processing equipment (such as numerical control machine tools, robots, etc.).

[0003] However, the existing numerical control feeder may have different feeding effects for materials of different hardness. For example, when feeding a metal material with high hardness (such as stainless steel plate), the feeding mechanism needs more driving force to push the material forward due to the large rigidity of the material. If the driving force of the feeder is insufficient, the feeding may be jammed, affecting the continuity and accuracy of the feeding. For materials with low hardness and soft texture (such as plastic film), if the pressure control of the feeding mechanism is improper, the material may be deformed or scratched, which will also affect the feeding accuracy.
