Abstract

The utility model provides a safety manipulator of punching machine, which relates to a safety device of operating machine tool, particularly a safety device of operating punching machine. The utility model uses the characteristic of the very large inertia, and let things slide. The safety manipulator of punching machine realizes that machine controls human by the transmission system of wire rope. The man and the machine move oppositely and synchronically to achieve the purpose of safe operation of punching machine. The utility model has the advantages of simple structure, compaction, easy production, low cost, visual protective action and safety.

Description

Safety manipulator of punching machine

The utility model is the safety guard in a kind of safety guard of machine operation, particularly operating punch machine.

Punch press is used very extensive in mechanical manufacturing field, and demand increases day by day, because punch press tonnage height, inertia is big, and speed is fast, and the operator is in the abominable noise circumstance that exceeds standard, carry out simple single action repetitive operation with 5000～6000 jig frequency every day, easily produce fatigue, thereby the life accident occurs repeatedly, our country just proposed to solve the safety problem of operating punch machine before 30 years, but never basic the solution.For a long time, people's design philosophy all concentrates on when the punch press drift glides the generation dangerous situation, how to take measures to make drift to stop, as the photoelectric sensing protector, even this protector control element is effective, but taking place at random, uncertain unexpected power failure, tripping operation and photoelectric circuit fault thereof take place, make device malfunctioning, cause drift inertia to glide, still dangerous; Whether in addition, this protective effect is not directly perceived, cannot see and can not touch, be psychologically can't sensing device really to work and frightened worried.And this photoelectric cell braking mechanism make complicated, the photoelectric cell rapid wear, braking mechanism is easy to failure, involve great expense.Also have a kind of baffle controls protective device at present, but its machinery too, hired roughneck does not at every turn possess manual randomness and uses inconvenience.

The purpose of this utility model overcomes above-mentioned shortcoming exactly; a kind of punching machine safety manipulator is provided; it utilizes punch press to have this inherent characteristic of very big inertia; let nature take its course; realize controlling the people by special transmission mechanism by machine; carry out mechanical protection control, reach the purpose of punching machine safety operation.

Technical solution of the present utility model is an end of steel wire rope to be taken turns through elevator be connected in the arbitrary position of slider of punch, and the steel wire rope other end is connected with bracelet with synchronous return spring through drive in managing again.

Figure below further specifies in conjunction with the accompanying drawings.

Accompanying drawing is the utility model structural representation.

As shown in the figure, according to the size of institute's use punch press model, the distance of selected the utility model and punch press is fixed base 2 usefulness foundation bolts 1 then as fixed point with ground, and external riser 3 is fixed on the base 2; Form seat by support bar 5, adjustable pipe 6, seat 7, operate use for the operator, seat 7 is fixed on the adjustable pipe 6, and adjustable pipe 6 is enclosed within on the support bar 5, and uses bolted, adjustable pipe 6 can be set up front and back on support bar 5, thereby seat 7 is adjusted front and back as required, and an end of support bar 5 is a right angle, and this end is connected with clamping plate 4, and can be in clamping plate 4 left rotation and right rotation, thereby seat is adjusted about in use can be as required; Clamping plate 4 are fixedly connected with external riser 3 by bolt and nut, and the lifting of seat on external riser 3 just realizes by tense-lax clamping plate 4. Bent sub 8 in the middle of also fixedly being equipped with on the external riser 3, middle bent sub 8 has externally threaded pipe fitting with pipe joint 24 by two ends and is connected. Be installed with drive 9 by bearing pin in pipe joint 24 1 ends, the other end of pipe joint 24 and spring guide 10 are flexibly connected by bolt. Return spring 12 is placed in the spring guide 10 synchronously, the one end is fixed on the inner of spring guide 10, the other end forms by threeway guiding joint 11 at 3 with bracelet 13 and steel wire rope 17 and connects, and threeway guiding joint 11 is placed in the spring guide 10, and can horizontally slip within it. External riser 3 inner sleeves have internal riser 14. Size according to punch press, regulate height of the present utility model by the length of lifting internal riser 14, the upper end of internal riser 14 is fixedly connected with an end of cantalever tube bent sub 15, by bearing pin drive 22 is housed fixedly in the bent sub 15, the other end of bent sub 15 is connected with an end of cantalever tube 16, and the other end of cantalever tube 16 is connected with Trolley case 18; Cantalever tube 16 also is the inner and outer pipes structure, and scalable adjusting is equipped with elevator wheel 19 by bearing pin in the Trolley case 18. The other end of steel wire rope 17 stretches out through cantalever tube 16 drives 22, internal riser 14, drive 9 from Trolley case 18 upper ends and is connected in the coupling head 11 of threeway guiding.

The utility model adopts the apparatus control people, makes man-machine form an interlock integral body, synchronous backward motion; its action is synchronous with operator's normal operating psychology and thinking, and very safe and reliable, the utility model is simple in structure; install easy to adjustly, use flexibly, protective effect is directly perceived.

Embodiment:

Behind the position according to middle bent sub 8 on the size of punch press, the span of adjusting height of the present utility model, cantalever tube 16 and punch press, the standpipe, be Trolley case 18 to be fixed on the punch press flywheel shaft bearing bolt with band iron shape accessory mount 20(accessory mount 20) be connected by bolt.One end hook of steel wire rope 17 is hung on the slider of punch locking bolt, and adjusts the length that fixes steel wire rope 17.During operation, the operator is sitting on the seat, and seat can be adjusted as required, and becket 13 kinks are in operator's palm of the hand tiger position.Like this; as long as operator's hand in the drift hazardous area when drift glides; then utilize any sliding force of punch press drift self to be power, drive connected steel wire rope 17 linkage bracelets 13 and make to contract behind operator's hand synchronous backward and leave the hazardous area, play effect operator's protection.When the punch press drift made progress return, steel wire rope 17 returned to original state with drift under the elastic reaction of fixed bit spring 12, prepared drift and worked next time.When the normal running of operator's hand is in the place of safety, the tractive of the synchronous backward action of steel wire rope 17 when not glided by the punch press drift.Because of operator's hand had been recovered to the place of safety before steel wire rope 17 effects, 17 on steel wire rope is done the idle running motion, and the operator can send arbitrarily and get workpiece, does not have compulsion because of bracelet 13 and makes that the operator does not feel well, is in the way, tired or other side effect.Have only when the contingency situation occurring, operator's hand does not leave the drift hazardous area, and bracelet 13 of the present utility model just meeting tractive operator's hand leaves the hazardous area, plays a protective role.
