Details, advantage and the feature of invention illustrate with the following example and accompanying drawing.But should only not be interpreted as the embodiment that this is limited to the protection domain that the present invention requires.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Accompanying drawing is the positive view of sliding C type safety protector.
1. sliding sleeve axles among the figure, 2. main spring, 3. check ring, 4. in the middle of pressure block, 5. pedestal, 6. Returnning spring, 7. slip feeler lever, 8. press machine lower slider, 9. nut, 10.T type bolt.
Embodiment
As shown in the figure, sliding C type safety protector (hereinafter to be referred as protector) is made up of pedestal (5), sliding sleeve axle (1), main spring (2), check ring (3), middle pressure block (4), slip feeler lever (7), Returnning spring (6), nut (9) and T type bolt parts such as (10).It is one flat uncovered that the side of pedestal (5) C type camber beam has, and the uncovered first half is that footstock, Lower Half are base.Pressure-bearing surface has that laterally steering groove, camber beam sidewall have that a ladder through hole, Returnning spring (6) place in the hole on the base, slip feeler lever (7) passes therethrough to tighten with middle pressure block (4) and join together, have below the middle pressure block (4) positioning boss, with hand push press slip feeler lever (7) make Returnning spring (6) compression, simultaneously promote in the middle of pressure block (4) slide, finally terminate under the axle head of sliding sleeve axle (1) along the open-mouth of guiding groove to camber beam.Footstock pressure-bearing end face center has that an axis hole with the level, sliding sleeve axle (1) have the shaft shoulder, down outer, the check ring (3) in the extended hole of end journal is used as its axial restraint, main spring (2) places in the axis hole on the step, provides spring-back force, sliding sleeve axle (1) to be free to slide in axis hole for sliding sleeve axle (1), at ordinary times during the press machine proper functioning, middle pressure block (4) is separated from sliding sleeve axle (1) center line, its pressure-bearing surface no longer the end contacts, this state is called normally open with sliding sleeve axle (1) under Returnning spring (6) elastic force effect.Under normally open, press ram is stoped by any object together with sliding sleeve axle (1) Shi Buhui that moves up and down.Pressure block (4) slides and inserts its axle head bottom to sliding sleeve axle (1) centerline direction and is called lock state when motionless to locking in the middle of slip feeler lever (7) promotes; when lock state, to have increased N centimetre, the difference of front and back both heights before the locking be exactly this safety protector design protection height to the protector total height, this highly belongs to level altitude, when accident is about to take place, can effectively stop mould up and down closure, form guard space, avoid taking place personal injury accident.Base pressure-bearing surface center has that a vertical axis hole with the level, T type bolt (10) penetrate from below wherein, head is stuck in press machine lower slider (8) the T type groove and with nut (9) it is tightened up.
The thickness N of pressure block (4) is the problem to be solved in the present invention key in the middle of rationally determining because the size of N determine protected space height, relevant with people's palm thickness, take all factors into consideration the N span 4-5 centimetre (present embodiment is 4 centimetres).For the protector that makes design can be contained in smoothly on the press machine, should be according to the protector of the difference apolegamy different heights of die size, the minimum design height of protector is measured under normally open: sliding sleeve axle (1) is pressed downwardly onto the end makes that its axle head touches the pedestal end face, the height measured from base bottom to sliding sleeve axle (1) upper-end surface is exactly minimum design height.The bulk between the slide block is greater than minimum design height more than 0.2 centimetre up and down after the mould closure, up and down as long as guarantee press machine during practical application.
The concrete course of action of present embodiment is as follows: protector is fixed on the press bench face appropriate location with T type bolt (10); protective baffle plate (not drawing among the figure) is fixed on a certain position of pressure frame sidewall; baffle plate places the front of slip feeler lever (7); pressure block (4) slided to the baffle plate direction together in the middle of Returnning spring (6) made slip feeler lever (7) pulling at ordinary times; protector is in normally open, owing to there is not the restriction of middle pressure block (4); press ram can therewith move down by pushing sliding sleeve axle (1) in the process that the drive mould moves downward; can not run into any obstruction.When the operator operates against regulations, opens moment, baffle plate that baffle plate removes to fetch in the mould workpiece with hand push and promote slip feeler lever (7) and slide to sliding sleeve axle (1) axle head bottom, just slack when upwards propping up up to the bottom of inserting sliding sleeve axle (1) and with it together with middle pressure block (4) fast along guiding groove.Because the intervention of middle pressure block (4), make sliding sleeve axle (1) upwards lifting N centimetre, the height that increases after the lifting be exactly in the middle of pressure block (4) if thickness, this moment press ram move downward and bump against sliding sleeve axle (1) downwards just can be because of can't again it being promoted be forced to stop.The kinetic energy that slide block itself stores passes on the press machine table top via sliding sleeve axle (1), middle pressure block (4), pedestal (5) and is released.Because having hindered the finger that the downward movement of slide block, the size that makes mould up and down can't closed form certain slit, this slit can hold the operator just, the lock height of protector exempts to be broken by machine.When accident treatment finishes, slide block upwards the operation back that begins to break away from sliding sleeve axle (1), workman arm is regained leave baffle plate, Returnning spring (6) makes slip feeler lever (7) the middle pressure block of pulling (4) slide to the initial position that baffle plate direction, protector are got back to normally open again together, but just proper functioning and be not subjected to any obstruction of press machine.
