Abstract
The utility model relates to a female die load limiting and fine-regulating structure of a hydraulic machine for powder, which comprises a top cylinder and a double-pole piston rod, wherein the lower cylinder port of the top cylinder is provided with a limiting pad, the tail end of the lower rod body of the double-pole piston rod is provided with a threaded part of which the diameter is smaller than that of the lower rod body, and the threaded part of the lower rod body is sequentially sleeved with a regulating bolt with a center hole, a threaded seat with an inner threaded hole and a lock nut from top to bottom; the regulating bolt is in threaded fit with the threaded seat, the diameter of the center hole is slightly bigger than that of the lower rod body, the lock nut is in threaded fit with the threaded part of the lower rod body, and the lower end surface of the threaded seat is provided with a boss embedded in the upper end surface of the lock nut. The distance between the limiting pad at the lower cylinder port and the regulating bolt is the female die loading height. The loading height can be lowered by moving the lock nut upwards to integrally move both the regulating bolt and the threaded seat upwards. When the lock nut can not be moved upwards any more, the distance between the regulating bolt and the limiting pad can be further shortened by rotating the regulating bolt. The structure provided by the utility model has the advantage of large regulation amplitude and is convenient to use.
Description
Technical field
The utility model relates to a kind of powder hydraulic press former spacing fine tuning structure of feeding, the powder hydraulic press former that particularly a kind of amplitude of accommodation the is big spacing fine tuning structure of feeding.
Background technology
The powder hydraulic press is used for metal dust is pressed into pie, makes metallic article by sintering again.During the compacting products of different specifications, former dress powder height is also different, and former dress powder height, is regulated stop nut and can be realized in lower piston rod position up and down when needing to regulate dress powder height by terminal stop nut of the lower piston rod of taking blame for others and the control of spacing pad distance.This kind structure amplitude of accommodation is little: because lower piston rod end thread portion must be located at the part that lower piston rod does not enter cylinder body, make that the spacing pad displacement of the downward cylinder mouth of stop nut is limited, can't realize the dress powder requirement of lower height, need to change the spacing pad and the stop nut of special shape, structure, use inconvenient.
The utility model content
The technical problems to be solved in the utility model provides the big powder hydraulic press former of a kind of amplitude of accommodation spacing fine tuning structure of feeding.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of powder hydraulic press former spacing fine tuning structure of feeding, comprise take blame for others, two rod piston rod, limit position pad of the following cylinder mouth of taking blame for others, the following body of rod end of two rod piston rods is provided with the threaded portion of diameter less than the following body of rod, and its innovative point is: be with the adjusting bolt of center drilling, the threaded block and the locknut of band internal thread hole on the described body of rod threaded portion down from the top down successively; Described adjusting bolt and threaded block threaded engagement, its center-hole diameter is slightly larger than down body of rod diameter, locknut and following body of rod threaded portion threaded engagement, the lower surface of threaded block is provided with the boss that embeds in the locknut upper surface.
Advantage of the present utility model is: spacing pad of following cylinder mouth and the distance of regulating between the bolt are the former work loading height, when needing to reduce work loading height, can by on move locknut and realize to regulate bolt and threaded block and move on the whole and get final product, and when on locknut can't be again, moving, bolt is regulated in rotation, thereby further shorten the distance of regulating between bolt and the spacing pad, the amplitude of accommodation is big, and is easy to use.
Description of drawings
Accompanying drawing is the utility model powder hydraulic press former spacing fine tuning structure schematic diagram of feeding.
The specific embodiment
As shown in drawings, comprise take blame for others 1, down the body of rod 2, spacing pad 3, regulate bolt 4, threaded block 5, locknut 6.
Above-mentioned taking blame for others established two rod piston rods in 1, and following cylinder mouth bolt has spacing pad 3, and the following body of rod 2 of two rod piston rods stretches out from cylinder mouth down, and its end is provided with one section threaded portion, and this threaded portion diameter is less than body of rod diameter down.
On the threaded portion of the following body of rod 2, be with the adjusting bolt 4 of center drilling, the threaded block 5 of band internal thread hole from the top down successively, and locknut 6., wherein, regulating bolt 4 locks with threaded block 5 internal and external threads, the center-hole diameter of regulating bolt 4 is slightly larger than down the diameter of the body of rod 2, locknut 6 and the following body of rod 2 threaded portion threaded engagement, the lower surface of threaded block 5 is provided with boss, and the upper surface of this boss and locknut is chimeric.
The distance of regulating between bolt 4 upper surfaces and spacing pad 3 lower surfaces is the reinforced height of former, in the time of need reducing to feed in raw material height, both can regulate bolt 4 by the rotation and locknut 6 jack-up of the following body of rod 2 threaded engagement, also can realize the change of height by the rotation and the adjusting bolt 4 of threaded block 5 threaded engagement, the amplitude of accommodation is big.
