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 the 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 to be processed, and the operator makes flywheel band movable slider and patrix complete a undershoot program by triggering arrangement of clutch when work.it is large that this punch press has operational risk, the characteristics that working strength is high, application number is that 201120186366.4 utility model has been 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 the feeding rod that horizontal linear moves back and forth feeding to the counterdie of lifting diel, be positioned at the raw material holder of feeding rod below, thereby between feeding rod and raw material holder and can move back and forth up and down and intermittently the raw material on the raw material holder be sent to the loader of feeding rod and be connected in feeding rod, loader and being used for drives the linkage driving device between the drift motion control rotating shaft that the horizontal cross of lifting diel elevating movement arranges, wherein be provided with magnetic material on feeding rod in order to adsorb to be processed, this autoloader has improved ram efficiency, ensured operator's safety, 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 to be processed to reverse to be processed at random, feeding can not accurately be put in place, this situation is particularly evident to be processed time performance in irregular shape, feeding rod in addition, loader connects drift motion control rotating shaft by the linkage driving device, and this is arranged on to exist in real operation and has a big risk, the characteristics that required precision is high, all strokes of feeder all depend on the drift motion, the drift motion continues in case feeder goes wrong, not only damage punch press itself, entail dangers to operator also.

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 addresses the above problem is: a kind of punch press in order to ironware processing comprises the 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 to be processed, also comprise a feeding head, drive unit, electromagnetic attraction device, control device, flip flop equipment; Drive unit is in order to driving the back and forth operation between feeding position and blowing position of feeding head, and the feeding position refers to that the feeding head meets the position when getting to be processed, and the blowing position is positioned at the station top and refers to feeding first to be processed the position when putting into station; The electromagnetic attraction device is arranged on the feeding head; Control device is in order to control the electromagnetic attraction device, be specially that to control the electromagnetic attraction device after the feeding head arrives the feeding position in running order and keep this state until the feeding head moves to the blowing position, control the electromagnetic attraction device and be in closed condition and keep this state until the feeding head moves to the feeding position after the feeding head arrives the blowing position; Flip flop equipment triggers arrangement of clutch so that the step that slide block and patrix are completed a undershoot, resetted in order to leave the blowing position at the feeding head after.it is in running order and keep this state until the feeding head moves to the blowing position that the present invention program's feeding head control device after arriving the feeding position is controlled the electromagnetic attraction device, this process guarantees that feeding head adsorbs to machined part and to be processed is transported to the blowing position from the feeding position, control device is controlled the electromagnetic attraction device and is in closed condition and keeps this state until the feeding head moves to the feeding position after the feeding head arrives the blowing position, this process guarantees to lose to machined part absorption after feeding head arrives the blowing position, to be processed falls into station naturally under self-gravity action, this shows the feeding head between feeding position and blowing position once back and forth operation just can complete the storing of to be processed, and to be processed put into station after electromagnetic attraction device on the feeding head close, thereby can not produce absorption affinity to it again and avoid this to be processed of random perturbation, guarantee the storing precision of to be processed, flip flop equipment triggers arrangement of clutch so that the step that slide block and patrix are completed a undershoot, resetted in order to leave the blowing position at the feeding head after, when the feeding head leaves the blowing position, to be processed storing completed, the feeding head is recessed the blowing position, flip flop equipment triggers arrangement of clutch so that slide block and patrix are completed an impulse stroke, the process of to be processed is completed, the punching stroke that this shows punch press is restricted by the feeding stroke, has reduced operational risk.

Technique scheme requires manually to deliver to the feeding position to be processed, is not easily, is necessary to be improved.
