Description

The break that is used for the rigid press safety protection device

One, technical field

The utility model relates to a kind of rigid press safety protection device, refers in particular to a kind of break that is used for the rigid press safety protection device.

Two, background technique

Rigid press (punch press, lathe) must be equipped with safety protection device, otherwise security incident takes place the operator easily.For this reason; the applicant has invented a series of punching machine safety devices: " punching machine safety device " (CN2214853Y; the December 13 nineteen ninety-five day for announcing); " the vertical safety protection device that is used for punch press " (CN2221454Y); " safety protector for rigid-clutch open presser " (CN1185377A; disclosed day on June 24th, 1998) and " override type rigid clutch pressing machine safety protection device " (CN2332507Y, August 11 1999 day for announcing) etc.As " safety protector for rigid-clutch open presser "; it is made up of infrared transmitter, infrared remote receiver, solid-state voltage stabilizing small power supply and electromagnetic brake; electromagnetic brake comprises clutch wheel, break and electromagnet part; electromagnet portion and brake groups are integral; brake grab or loosen clutch wheel; brake support frame head opening becomes splayed shape; card is welded on the support plate; electromagnet core passes support plate; housing is installed on the support plate; break two is pitched a draught animals and is contained two rollers, passes support and fixes with pin, and the other end is connected with iron core.It can be used for the rigid-clutch open presser of various tonnages.But these patents and present commercially available like product all require lathe (press machine) is reequiped or increased the job key that specialized spare part (as clutch wheel, ratchet etc.) is controlled the lathe clutch, reach lathe clutch separation or combination; And, in operating process, be exactly under the situation of proper functioning, they are all being worked at random continually, directly influence the working life of safety protection device.

Three, model utility content

The purpose of model utility is to overcome the above-mentioned defective that prior art exists; a kind of break that is used for the rigid press safety protection device is provided, uses its lathe not do any repacking, also do not need to increase other component; and its frequency of okperation is little, long service life.

For achieving the above object; the solution that the utility model is taked is: a kind of break that is used for the rigid press safety protection device; in the middle of the main casing of this break is straight inner chamber; horizontal inner chamber is arranged at the bottom; straight inner chamber communicates with horizontal inner chamber; fixing main electromagnetic coil in the straight inner chamber top wall of main casing; the outside thread guide rod that has block below passes the guide pillar that a side has some recessed sawtooth; brake tooth is set below the guide pillar; the center is that the iron core of screw is from being screwed into guide rod; iron core is from filling in the straight inner chamber of main casing down; big stage clip is from being inserted in guide rod; guide rod passes bonnet; bonnet is fixed on above the main casing; the screw top diameter of iron core wherein forms a step greater than the bottom diameter; endoporus bottom diameter wherein forms a step greater than the top diameter in the bonnet; big stage clip lower end contacts with step in the iron core; the upper end contacts with step in the bonnet; fixing self-locking electromagnetic coil in the horizontal internal chamber wall of main casing; the self-locking iron core inserts the horizontal inner chamber of main casing; self-locking iron core one end face has the protruding sawtooth that is meshed with the recessed sawtooth in guide pillar side; the other end has groove; small pressure spring one end inserts the groove in the self-locking iron core; the other end inserts the groove of self-locking coil lid the inside; the self-locking coil lid is fixed in main casing; tenminal block is fixed on the main casing outside, and tenminal block is electrically connected with main electromagnetic coil and self-locking electromagnetic coil by the passage in the main casing.

The utility model and safe light curtain, slide block positioning work piece and the supporting use of electric control box constitute the rigid press safety protection device.Assemble lathe of the present utility model and do not do any repacking, also do not need to increase other component.Lathe is under normal operation, because main electromagnetic coil and self-locking electromagnetic coil all are under the energising situation, iron core adhesive under the effect of the electromagnetic force that main electromagnetic coil produces (big stage clip compression) remains static, the adhesive (small pressure spring compression) under the effect of the electromagnetic force that the self-locking electromagnetic coil produces of self-locking iron core remains static, do not pin guide pillar, simultaneously because the effect of guide rod all remains static after pulling on guide pillar and brake tooth, so its frequency of okperation is little, long service life.In case the violating the regulations or misoperation of operator occurs; that is to say; operator's hand is also in the hazardous area of lathe or the lathe slide block has begun to move downward and the operator stretches into hand the hazardous area again; at this moment the slide block positioning work piece is in the shading state to light pipe; safe light curtain is in the shading state; make electric control box send the power supply that braking instruction cuts off break; the break dead electricity is main electromagnetic coil and self-locking electromagnetic coil dead electricity; under the elastic force effect of big stage clip, lathe clutch job key is blocked in the brake tooth ejection; clutch separates rapidly; the slide block stop motion because the elastic force effect of small pressure spring makes the self-locking iron core pin guide pillar, has reached the purpose of safety protection.
