Abstract
The utility model relates to a slider locking mechanism of a single-acting frame stretching press, which comprises a frame and a slider disposed below a crossbeam on the frame. The slider locking mechanism is characterized in that a ratchet bar which extends perpendicularly is mounted on a side wall of the slider, a hydraulic cylinder is mounted on an upright column, which is opposite to the ratchet bar, of the frame, and a ratchet is connected to the end of the hydraulic cylinder. The slider locking mechanism has the advantages that the hydraulic cylinder pushes the ratchet to move forwards, so that the ratchet is embedded in a tooth space of the ratchet bar, the ratchet bar is prevented from moving downwards, and accordingly the slider is locked. The slider does not need to return to an upper stop point to be locked, a locking range is large, and spatial running time is shortened.
Description
Technical field
The utility model relates to a kind of framework single action stretching press, particularly a kind of sliding block locking mechanism of framework single action stretching press.
Background technology
The sliding block locking mechanism of framework single action stretching press is used for slide block locking, and anti-limited slip block plunks down when quitting work and causes the accident.Traditional sliding block locking mechanism comprises the connecting rod that is fixedly connected with slide block, and the top of this connecting rod has pin-and-hole, and the little hydraulic jack of horizontal direction is set in the press entablature, and the top of this little hydraulic jack connects bearing pin.When needing the locking slide block, move on the slide block, make connecting rod top pin-and-hole and bearing pin be positioned on the same horizontal line, little hydraulic jack ejects, and bearing pin inserts and realizes locking in the pin-and-hole.The shortcoming of this kind structure is: slide block must be got back to top dead centre, makes the pin-and-hole aligning bearing pin of connecting rod could realize locking, has increased the no-load running of slide block.
Summary of the invention
But the technical problem that the utility model will solve provides the sliding block locking mechanism of the framework single action stretching press of a kind of optional position locking.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of sliding block locking mechanism of framework single action stretching press; Comprise framework, be located at the slide block of framework entablature below, its innovative point is: the sidewall of said slide block is equipped with the ratchet bar that vertical direction is extended; On the upright of frame of ratchet bar, hydraulic jack is being installed, the end of this hydraulic jack is connected with ratchet.
The advantage of the utility model is: promote the ratchet reach through hydraulic jack, make ratchet embed in the teeth groove of ratchet bar, prevent that ratchet bar from moving down, promptly accomplish the locking of slide block.Need not slide block and get back to top dead centre realization locking, the locking scope is big, has reduced the space motion time.
Description of drawings
Fig. 1 is the sliding block locking mechanism structural representation of the utility model framework single action stretching press.
The specific embodiment
As shown in Figure 1, comprise slide block 1, ratchet bar 2, hydraulic jack 3, ratchet 4, bearing 5.
Above-mentioned slide block 1 is positioned at the entablature below of press frame; The sidewall of slide block 1 is equipped with the ratchet bar 2 that vertically extends; On the upright of frame of ratchet bar 2, hydraulic jack 3 is being installed, ratchet 4 is located at the place ahead of hydraulic jack 3, is installed on the bearing 5; The end of ratchet 4 is connected with the column bearing pin, and the piston rod of hydraulic jack 3 is connected with the middle part of ratchet 4 through connecting rod.Under the effect of hydraulic jack 3, ratchet 4 can rotate the teeth groove that embeds or break away from ratchet bar 2 around bearing pin.
Promote ratchet 4 reaches through hydraulic jack 3, make ratchet 4 embed in the teeth groove of ratchet bar 2, prevent that ratchet bar 2 from moving down, and promptly accomplishes the locking of slide block 1.Need not slide block and get back to top dead centre realization locking, the locking scope is big, has reduced the space motion time.
