Abstract
The utility model discloses an anti-drop device for a slide block of a punch. The anti-drop device comprises a slide block, wherein an anti-drop support is arranged above the slide block; a notch is formed in the anti-drop support; a connecting rod is fixedly connected with the top of the slide block and penetrates through the notch; a cylinder is also arranged on the anti-drop support; the free end of a piston rod of the cylinder is fixedly connected with a fixing lock pin; a strip-type through hole through which the fixing lock pin penetrate is formed in the connecting rod; the longitudinal height of the strip-type through hole is larger than the adjustment amount of the slide block; a fixing lock pin hole is also formed in the anti-drop support; the size of the fixing lock pin corresponds to the size of the fixing lock pin; an electrical detector which judges whether the slide block is locked according to the travel distance of the piston rod is connected with the cylinder; and the electrical detector is electrically connected with the piston rod. By the anti-drop device for the slide block of the punch, when the punch is stopped by an operator for die repair or die adjustment, the slide block is stopped at a dead point position; and the cylinder state is adjusted through an operation panel, so that personal safety of the operating personnel is well guaranteed, and damage to the punch is avoided.
Description
Technical field
The utility model 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 the automatically down landing of slide block this moment is if just have this moment the operative employee can cause unexpected injury when work top carries out the work of maintenance die debugging mould.
Summary of the invention
The utility model mainly is to solve the deficiency that existing slide block automatically glides and exists, and a kind of slide block anti-drop device of punch press is provided, and avoids voluntarily landing of slide block, avoids potential safety hazard.
The utility model solves the problems of the technologies described above the technical scheme that adopts:
A kind of slide block anti-drop device of punch press includes slide block, and described slide block top is provided with anti-fall bearing, has the breach of vertical layout on the described anti-fall bearing, and described slider top is connected with the connecting rod of vertical layout, and described connecting rod runs through described breach; On the described anti-fall bearing cylinder is installed also, the piston rod of cylinder is horizontally disposed, the free end of described piston rod is connected with horizontally disposed solid lock pin, and described connecting rod is provided with the rectangular through hole that runs through for solid lock pin, and vertical height of described rectangular through hole is greater than the slide block adjustment amount; Also have the solid lockpin hole with the breach interlaced arrangement on the described anti-fall bearing, the size of described solid lockpin hole is suitable with solid lock pin size, closely cooperates; Be connected with on the described cylinder according to the stroke distances of piston rod and judge whether locked electric checkout gear of slide block, described electric checkout gear is electrically connected with piston rod.
Described connecting rod is affixed by solid split nut and slide block.
Described cylinder is provided with that the cylinder front limit detects a little and rear spacing detecting a little, cooperates with described electric checkout gear.
Operation principle of the present utility model is: cylinder drives solid lock pin and pushes in the solid lockpin hole of anti-fall bearing, (it is fixed that the slide block upper dead center position comes by slide block adjustment amount at that time will admittedly to be locked in the slide block upper dead center position with the affixed connecting rod of slide block, 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, the left hand cylinder front limit detects or the right cylinder front limit does not detect just and can detect, just can will unusually be sent to man-machine interface this moment, thereby prompting operation worker ejects the cylinder abnormal, please don't keep in repair or debug mould.To eject cylinder and unusually eliminate, and make liftout attachment reach indicating positions, and detect affirmation and the solid lock side of connecting rod can be carried out maintenance die through spacing.Otherwise lathe before work, the adjusting cylinders duty, Gu lock pin throw off, until reach indicating positions, without the bed normal operation of can starting shooting on unusual opportunity.
The beneficial effects of the utility model are: shut down the operative employee and repair a die or slide block is parked in upper dead center position during mode transfer; then regulate by the cylinder state on the guidance panel; 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 the utility model structural representation.
The specific embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, 2, a kind of slide block anti-drop device of punch press includes slide block 5, described slide block top is provided with anti-fall bearing 1, have the breach of vertical layout on the described anti-fall bearing, described slider top is connected with the connecting rod 3 of vertical layout, and described connecting rod runs through described breach; On the described anti-fall bearing cylinder 6 is installed also, the piston rod of cylinder is horizontally disposed, the free end of described piston rod is connected with horizontally disposed solid lock pin 2, and described connecting rod is provided with the rectangular through hole 11 that runs through for solid lock pin, and vertical height of described rectangular through hole is greater than the slide block adjustment amount; Also have the solid lockpin hole with the breach interlaced arrangement on the described anti-fall bearing, the size of described solid lockpin hole is suitable with solid lock pin size, closely cooperates; Be connected with on the described cylinder according to the stroke distances of piston rod and judge whether locked electric checkout gear of slide block, described electric checkout gear is electrically connected with piston rod.Described connecting rod is affixed with slide block by solid split nut 4.Described cylinder is provided with the cylinder front limit and detects a little 7 and spacingly detect a little 8 afterwards, cooperates with described electric checkout gear.
Claims (3)
