Abstract
The utility model discloses a punch press safety guard. The punch press safety guard comprises an ejector rod, a shifting fork, a sliding table and an electromagnet. The sliding table comprises a bottom plate, a side plate, a cushion block and two sliders. Two slide grooves matched with the two sliders in width are formed in the bottom plate, the side plate and the cushion block are oppositely fixed at the two ends of the bottom plate respectively, and the two sliders are arranged in the slide grooves respectively. The shifting fork comprises traction rod, a shifting fork plate and a supporting rod, wherein the traction rod is hinged to the upper end of the shifting fork plate, and the supporting rod is fixed to the lower end of the shifting fork plate and protrudes toward the side plate. On the basis that a photo-electric safety device is installed on a punch press, the punch press safety guard of the scheme is further installed on the punch press, the shifting fork can be controlled through the electromagnet so as to prevent the ejector rod from falling off, and thus a punch is prevented from falling off to injure workers. Therefore, when the photo-electric safety device has a fault, the punch press safety guard can have an effective protective effect and protect personal safety of the workers comprehensively.
Description
Technical field
The utility model relates to the punching machine safety field, is specifically related to punch safety protection device.
Background technology
In the production of stamping parts, due to operate miss, the frequent wound occurred refers to operating personnel, severed finger etc. crushes, the damage to person accident of pinch off and so on, is perplexing the punch process industry always.For this reason, existing punch press generally all is provided with the secure ram protector, wherein best with photo-electric protective device effect.
The photo-electric protective device is combined by a set of optoelectronic switch and mechanical device, and when operator's hand enters in the mould district, light beam is obstructed, and sends the signal of telecommunication, thus reach slide block stop action, can not be descending purpose, guarantee operator's safety.Because the photo-electric protective device is easy to use, substantially noiseless to operation, therefore application is wider.
But the photo-electric protective device exists an insoluble problem, if be exactly when punch press burst mechanical breakdown staff just in time below the punch press drift, will cause the generation of security incident.
The utility model content
Technical problem to be solved in the utility model is while solving punch press burst mechanical breakdown, the problem that the photo-electric protective device can't normally protect.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is to provide a kind of punch safety protection device, comprise push rod, fork, slide unit and electromagnet, described slide unit comprises base plate, side plate, cushion block and two slide blocks, described base plate be provided with two with two chutes that described slide block width is suitable, described side plate and described cushion block relatively are fixed on respectively the two ends of described base plate, and two described slide blocks are placed in respectively in described chute; Described fork comprises draw bar, fork plate and pole, and described draw bar is hinged on described fork plate upper end, and described pole is fixed on the lower end of described fork plate, and protruding in described side plate; Described push rod and slide unit are separately positioned on the upper table surface and following table of described punch press, described electromagnet is arranged on described punch press the position suitable with described draw bar adhesive, described fork plate is hinged between two described slide blocks by the first bearing pin, and described fork is realized separating and adhesive by gauge tap with described electromagnet.
In such scheme, described push rod is arranged on the upper table surface of described punch press by the mode clamped or be threaded.
In such scheme, the rectangular bent plate shape of described fork plate, and described the first bearing pin is hinged on the bight of described fork plate.
The utility model; at punch press, be equipped with on the basis of photoelectric protector; the punch safety protection device of this programme is installed; thereby stop the push rod landing by the magnet control fork; stop thus drift to fall and injure the workman by a crashing object; therefore, after photoelectric protector breaks down, can play effective protective action, reach the effect of general protection workman personal safety.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The structural representation that Fig. 2 is fork in the utility model;
The structural representation that Fig. 3 is slide unit in the utility model;
The structural representation that Fig. 4 is the normal operation of punch press in the utility model;
Fig. 5 is the structural representation that in the utility model, punch press breaks down under the protector guard mode.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As Figure 1-3, the utility model provides a kind of punch safety protection device, comprises push rod 1, fork 2, slide unit 3 and electromagnet 4.Wherein, slide unit 3 comprises base plate 8, side plate 9, cushion block 10 and two slide blocks 11, base plate 8 be provided with two with two chutes that the slide block width is suitable; Fork 2 comprises draw bar 5, fork plate 6 and pole 7, and draw bar 5 is hinged on fork plate 6 upper ends by the second bearing pin, and pole 7 is threaded connection on the other end of fork plate 6.
Push rod 1 and slide unit 3 are separately positioned on the upper table surface and following table of punch press, push rod 1 is arranged on the upper table surface of punch press by the mode clamped or be threaded, electromagnet 4 is arranged on punch press the position suitable with draw bar 5 adhesives, fork plate 6 is hinged between two slide blocks 11 by the first bearing pin, draw bar 5 is oppositely arranged with electromagnet 4, and controls separating and adhesive of draw bar 5 and electromagnet 4 by gauge tap.
As shown in Figure 4, when with hand, pressing gauge tap, draw bar 5 and electromagnet 4 adhesives, draw bar 5 is attracted and is moved to the left, drive fork 2 integral body and rotate counterclockwise around the first bearing pin, thus make push rod 1 in dropping process without any obstruction, free-falling is to the base plate 8 of slide unit 3, realize a punching press action, punching apparatus is in normal punching course;
As shown in Figure 5, when both hands leave gauge tap, draw bar 5 separates with electromagnet 4, fork 2 resets, push rod 1 and fork plate 6 above-below directions are on same straight line, once now break down, push rod 1 can directly drop on fork plate 6 downwards, fork plate 6 clockwise rotates around the first bearing pin, so pole 7 is against on the side plate 9 of slide unit 3, promoting slide block 11 drive fork plates 6 and push rod 1 moves right, push rod 1 is finally moved on the cushion block 10 on slide unit 3, blocking push rod 1 continues to fall, thereby stop drift to fall on base plate 8, reach the purpose of protection operator both hands.
The utility model; at punch press, be equipped with on the basis of photoelectric protector; the punch safety protection device of this programme is installed; thereby stop the push rod landing by the magnet control fork; stop thus drift to fall and injure the workman by a crashing object; therefore, after photoelectric protector breaks down, can play effective protective action, reach the effect of general protection workman personal safety.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, within all falling into protection domain of the present utility model.
