Description
Technical field
The utility model relates to mechanical equipment field, a kind of specific automatic bar feeder with double fastener material group.
Background technique
Automatic lathe or numerically controlled lathe need automatic bar feeder matched with its automatically complete when being produced in batches
At feeding, blanking and the work of feeding.Bar of the pile on automatic bar feeder material frame falls into expects pipe by cutting agency
In after, first have to be fixed by feeding clip mechanism, then push rod (including the axis being connected with push rod and is mounted on axis
Feed collet) it travels forward under the action of feeding motor, feed collet is socketed in bar end, completes the charging of bar.Charging is completed
Afterwards, feeding clip mechanism unclamps, and bar can travel forward under the action of push rod, carries out feeding.Automatic bar feeder exists at present
When clamping conventional bar (4mm or more bar), generallys use single clip mechanism and complete charging, but this kind of scheme is thinner for clamping
When bar, generally existing following problem:
1, thinner material stiffness is lower, is easily deformed, and when clamping bar, bar can run-off the straight, relatively reason for single clip mechanism
It is deviated to the left or to the right by position；
It 2, must there are between unilateral 0.5mm or more between push rod and expects pipe in order to guarantee that push rod can be smooth by expects pipe
Gap, and push rod stress point, in rear end, feed collet is in its front end, due to gravity, the practical center position of feed collet is relative to pushing away
The theoretical central axes of bar be it is on the lower side, will also result in feed collet center and bar center to be held in this way, there are certain dislocation；
3, the collet of single clip structure is V-type on one side, is tooth form on one side, and bar enters negative area in V-type when clamping, is held
Easily lead to material bending；
Under the action of above several factors, more serious mistake often occurs for the center of the center of feed collet and thin bar
Position, at bar misalignment feed collet center, bar is just not easily accessed feed collet, if being mistaken for bar comes into feed collet, pushes away
Bar will result in push rod when advancing and stuck shutdown occurs for bar.
