Description

A kind of punch press in order to ironware processing

Technical field

The present invention program relates to a kind of technical field of the punch press in order to ironware processing.

Background technology

Punch press comprises lathe bed matrix as a kind of common device, flywheel, arrangement of clutch, slide block, be arranged at the patrix on slide block, the counterdie corresponding with patrix, counterdie forms station in order to the place of putting workpiece to be added, and operationally operator makes flywheel band movable slider and patrix complete a undershoot program by triggering arrangement of clutch.It is large that this punch press has operational risk, the feature that working strength is high, application number be 201120186366.4 utility model made useful improvement, a kind of automatic feeder for punch is disclosed, it comprises frame, frame is provided with and is positioned at lifting diel side and can carries out to the counterdie of lifting diel the feeding rod that horizontal linear moves back and forth feeding, be positioned at the raw material holder below feeding rod, can move back and forth up and down thus intermittently the raw material on raw material holder be sent to the loader of feeding rod and be connected to feeding rod between feeding rod and raw material holder, linkage driving device between loader and the drift motion control rotating shaft being used for driving the horizontal cross being elevated diel elevating movement to arrange, wherein feeding rod is provided with magnetic material in order to adsorb workpiece to be added, this autoloader improves ram efficiency, ensure the safety of operator, but still there are some shortcomings in this technical scheme: the magnetic material on feeding rod keeps often inhaling state to machined part, this can cause feeding rod magnetic material when diel place is forced to unload workpiece to be added likely to reverse workpiece to be added at random, feeding can not accurately be put in place, it is particularly evident that this situation shows when workpiece to be added is in irregular shape, feeding rod in addition, loader connects drift motion control rotating shaft by linkage driving device, and this is arranged in real operation to exist and has a big risk, the feature that required precision is high, the all strokes of feeder all depend on that drift moves, once feeder goes wrong and drift motion continuation, not only damage punch press itself, also entail dangers to operator.

Summary of the invention

The technical problem that the present invention program will solve is the present situation for prior art, provides a kind of simple and reasonable, easy to operate, the feeding of energy automatic, high precision, safe and reliable a kind of punch press.

The technical scheme that the present invention program solves the problem is: a kind of punch press in order to ironware processing, comprises lathe bed matrix, flywheel, arrangement of clutch, slide block, is arranged at the patrix on slide block, the counterdie corresponding with patrix, counterdie forms station in order to the place of putting workpiece to be added, also comprise a feeding head, drive unit, electromagnetic attraction device, control device, flip flop equipment; Drive unit back and forth runs between feeding position and discharge position in order to drive feeding head, and feeding position refers to that feeding head meets position when getting workpiece to be added, position when discharge position is positioned at and refers to above station that station put into by the first workpiece to be added of feeding; Electromagnetic attraction device is arranged on feeding head; Control device is in order to control electromagnetic attraction device, be specially and arrive at feeding head that to control electromagnetic attraction device behind feeding position in running order and keep this state until feeding head moves to discharge position, after feeding head arrives discharge position, control electromagnetic attraction device be in closed condition and keep this state until feeding head moves to feeding position; Flip flop equipment in order to trigger arrangement of clutch with the step making slide block and patrix complete a undershoot, reset after feeding head leaves discharge position.It is in running order and keep this state until feeding head moves to discharge position that the feeding head of the present invention program control device behind arrival feeding position controls electromagnetic attraction device, this process ensures that feeding head adsorbs to machined part and workpiece to be added is transported to discharge position from feeding position, after feeding head arrives discharge position, control device control electromagnetic attraction device is in closed condition and keeps this state until feeding head moves to feeding position, this process ensures that feeding head loses absorption after arriving discharge position to machined part, workpiece to be added naturally falls into station under self-gravity action, the once reciprocal operation of feeding head between feeding position and discharge position just can complete the storing of a workpiece to be added as can be seen here, and the electromagnetic attraction device after station put into by workpiece to be added on feeding head is closed, can not absorption affinity be produced to it again thus avoid this workpiece to be added of random perturbation, ensure the storing precision of workpiece to be added, flip flop equipment in order to trigger arrangement of clutch with the step making slide block and patrix complete a undershoot, reset after feeding head leaves discharge position, when feeding head leaves discharge position, work-piece to be added completes, feeding head recesses discharge position, flip flop equipment triggers arrangement of clutch and completes an impulse stroke to make slide block and patrix, the process of workpiece to be added completes, the punching stroke of punch press restricts by feeding stroke as can be seen here, reduces operational risk.
