Intermittent high-frequency reciprocating feeding mechanism

Abstract

The invention relates to an intermittent high-frequency reciprocating feeding mechanism, which is characterized by comprising a cam, a connecting rod, a return spring, a swinging rod, a drive structure and a push rod, wherein, the cam rotates around a fixed pivot; the connecting rod can slip forwards and backwards horizontally, the front end of the connecting rod is equipped with a revolvable roller, and the circumferential surface of the roller is contacted with that of the cam; the return spring acts on the rear end of the connecting rod; the swinging rod is vertically arranged, the lower end of the swinging rod is connected with the middle part of the connecting rod through a first joint bearing, and the middle part of the swinging rod is equipped with a second joint bearing taken as aswinging pivot of the swinging rod; the drive structure drives the second joint bearing to slip up and down along the swinging rod; and the push rod can slip forwards and backwards horizontally, and the rear part of the push rod is hinged with the upper end of the swinging rod. In the invention, the push rod can perform intermittent high-frequency horizontal reciprocating motion under the swinging action of the swinging rod so as to realize intermittent high-frequency feeding; and the drive structure can drive the second joint bearing to slip up and down along the swinging rod, which causes length change of two ends of the pivot of the swinging rod so as to realize feed stroke adjustment.

Description

technical field [0001] The invention relates to an intermittent high-frequency reciprocating feeding mechanism. Background technique [0002] In order to improve the working efficiency of the stamping machine and realize automatic and safe stamping, we will set up an automatic feeding mechanism on the stamping machine. The traditional feeding mechanism generally has two forms. The first one is to use the main shaft to realize feeding through the crank and swing rod mechanism, such as a Chinese utility model patent "Stamping machine tool continuous punching automatic feeding" whose patent number is ZL95221233.1 (notification number is CN2230635Y). Giving device", and such as the Chinese utility model patent "Numerical Control High-Speed ​​Precision Chain Plate Automatic Punching Machine" whose patent number is ZL02266922.1 (notification number is CN2589115Y) all discloses a similar feeding mechanism. This kind of feeding mechanism is continuous reciprocating feeding, which c...

Problems solved by technology

The aforementioned feeding mechanism can realize intermittent feeding, but the feeding frequency is low

[0004] Regardless of the aforementioned feeding mechanism, the maximum feeding stroke is fixed. If the punching machine needs to change the feeding stroke, it is necessary to reinstall or replace the feeding structure, which is quite inconvenient to use.
