Abstract
The invention discloses a slide block falling-prevention device of a punching press, wherein the slide block falling-prevention device of the punching press comprises a slide block; a falling-prevention support is arranged above the slide block; a notch is formed in the falling-prevention support; a connecting rod is fixedly connected with the top of the slide block; the connecting rod runs through the notch; an air cylinder is also installed on the falling-prevention support; a free end of a piston rod of the air cylinder is fixedly connected with a fixed locking pin; the connecting rod is provided with a long-stripped through hole for the fixed locking pin to pass; the longitudinal height of the long-stripped through hole is greater than the adjustment amount of the slide block; a fixed locking pin hole is also formed in the falling-prevention support; the dimension of the locked locking pin hole is equivalent to the dimension of the locked locking pin; the air cylinder is connected with an electric detection device which determines whether the slide block is locked deadly according to the stroke distance of the piston rod; and the electric detection device is electrically connected with the piston rod. According to the invention, when an operator stops to repair a die or debug the die, the slide block is stopped on an upper dead point part, then the slide block is adjusted through the state of the air cylinder on an operating panel, at the moment, an important protection effect is realized on the human safety of the operating personnel, and no harm can be caused to the punching press.
Description
Technical field
The present invention relates to a kind of slide block anti-drop device of punch press.
Background technology
At present; Punch press in use because some factor causes clutch brake accidental damage, when engaging with flywheel; Because the slide block deadweight adds upper mould weight; Balancer breaks down, and slide block down landing automatically this moment is if just can cause unexpected injury when the operative employee keeps in repair the die debugging mould on work top work is arranged this moment.
Summary of the invention
The present invention solves the deficiency that existing slide block glides automatically and exists, and a kind of slide block anti-drop device of punch press is provided, and avoids slide block landing voluntarily, avoids potential safety hazard.
The present invention solves the problems of the technologies described above the technical scheme that is adopted:
A kind of slide block anti-drop device of punch press includes slide block, and said slide block top is provided with anti-fall bearing, has the breach of vertical layout on the said anti-fall bearing, and said slider top is connected with the connecting rod of vertical layout, and said connecting rod runs through said breach; On the said anti-fall bearing cylinder is installed also; The piston rod horizontal arrangement of cylinder; The free end of said piston rod is connected with the solid lock pin of horizontal arrangement, and said connecting rod is provided with the rectangular through hole that supplies solid lock pin to run through, and vertical height of said rectangular through hole is greater than the slide block adjustment amount; Also have the solid lockpin hole with the breach interlaced arrangement on the said anti-fall bearing, the size of said solid lockpin hole is suitable with solid lock pin size, closely cooperates; Be connected with on the said cylinder according to the stroke distances of piston rod and judge the electrical device that slide block is whether locked, said electrical device is electrically connected with piston rod.
Said connecting rod is affixed through solid split nut and slide block.
Said cylinder is provided with the cylinder front limit and detects a little and spacing the detecting a little in back, cooperates with described electrical device.
Operation principle of the present invention is: cylinder drives solid lock pin and pushes in the solid lockpin hole of anti-fall bearing; Will with the affixed connecting rod of slide block be locked in admittedly the slide block upper dead center position (it is fixed that the slide block upper dead center position comes by slide block adjustment amount at that time, with slide block be adjusted into maximum norm when high then near the lower end position of rectangular through hole, when slide block be transferred to minimum modulus when high then near apical position;); When if cylinder does not reach assigned address when pushing solid lockpin hole, just the left hand cylinder front limit detects or the right cylinder front limit does not detect and can detect, this moment just can be with being sent to man-machine interface unusually; Thereby prompting operation worker ejects cylinder takes place please don't keep in repair or debug mould unusually.To eject cylinder and eliminate unusually, and make liftout attachment reach indicating positions, and detect affirmation and connecting rod has been locked admittedly and can be keeped in repair mould through spacing.Otherwise lathe is regulated gas cylinder working condition before work, solid lock pin disengagement, and up to reaching indicating positions, the lathe operate as normal of can starting shooting when no abnormal.
Beneficial effect of the present invention is: shut down the operative employee and repair a die or slide block is parked in upper dead center position during mode transfer; Regulate through the cylinder state on the guidance panel then; Just play the protective effect of emphasis, and also can not cause any infringement to punch press this moment for operating personnel's personal safety.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of slide block anti-drop device of punch press includes slide block 5; Said slide block top is provided with anti-fall bearing 1; Have the breach of vertical layout on the said anti-fall bearing, said slider top is connected with the connecting rod 3 of vertical layout, and said connecting rod runs through said breach; On the said anti-fall bearing cylinder 6 is installed also; The piston rod horizontal arrangement of cylinder; The free end of said piston rod is connected with the solid lock pin 2 of horizontal arrangement, and said connecting rod is provided with the rectangular through hole 11 that supplies solid lock pin to run through, and vertical height of said rectangular through hole is greater than the slide block adjustment amount; Also have the solid lockpin hole with the breach interlaced arrangement on the said anti-fall bearing, the size of said solid lockpin hole is suitable with solid lock pin size, closely cooperates; Be connected with on the said cylinder according to the stroke distances of piston rod and judge the electrical device that slide block is whether locked, said electrical device is electrically connected with piston rod.Said connecting rod is affixed with slide block through solid split nut 4.Said cylinder is provided with the cylinder front limit and detects a little 7 and detect a little 8 with the back is spacing, cooperates with described electrical device.
