Description
Technical field
The utility model relates to powder metallurgical technology, particularly a kind of plug being applied to the elongated thin-wall product mould of powder metallurgy pressing.
Background technology
PM technique is a kind of precision molding technology, powder stock direct pressing can be few surplus by it, without the blank of surplus or clean shape part, thus process of producing product is simplified, and reduces work hours, materials microstructure can be made even, and performance is improved simultaneously.During the elongated thin-wall product of current press, adopt conventional unidirectional compacting or two-way compacting, all can cause Density inhomogeneity, deformation of products is large, easily from the region breakage fracture that middle Density Distribution is low; Need to use the method compacting that die or plug float and solve above problem.But the press possessing this function is all expensive large-scale press, and economy is inapplicable, and mechanism is complicated, and mould cost is high, production efficiency is low.
Utility model content
In order to address the aforementioned drawbacks, the purpose of this utility model is the movable plug providing a kind of powder metallurgy pressing mould, on the press device of common compact, realizes compacting of floating, reduces production cost.
The technical solution of the utility model is: a kind of movable plug of powder metallurgy pressing mould, comprise plug, transition connecting rod, guiding core, fairlead, exterior lock tube, wherein exterior lock tube assembles transition connecting rod from top to bottom successively, guiding core, fairlead, the upper end of transition connecting rod passes from the upper end through hole of exterior lock tube and is threaded with plug lower end, stage clip is provided with between guiding core and fairlead, the top, upper end of guiding core is pressed in the lower end of transition connecting rod, the lower end of guiding core is pierced in the guide through hole of fairlead, the upper end of fairlead is threaded with the lower end of exterior lock tube, the lower end of fairlead is provided with external screw thread.
Described transition connecting rod and plug junction are provided with stop nut.
The beneficial effects of the utility model are, structure is simple, on the press device of common compact, realizes compacting of floating, qualified elongated thin-wall product can be extruded, good product quality, dimensional accuracy is high, almost without machining, save man-hour, utilize the component that the utility model provides, reduce mould and equipment cost, be applicable to produce in enormous quantities.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: 1-plug, 2-stop nut, 3-transition connecting rod, 4-exterior lock tube, 5-stage clip, 6-leads core, 7-fairlead.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Fig. 1, the movable plug of a kind of powder metallurgy pressing mould that the utility model provides, comprise plug 1, transition connecting rod 3, guiding core 6, fairlead 7, exterior lock tube 4, wherein exterior lock tube 4 assembles transition connecting rod 3 from top to bottom successively, guiding core 6, fairlead 7, the upper end of described transition connecting rod 3 passes from the upper end through hole of exterior lock tube 4 and is threaded with plug 1 lower end, stage clip 5 is provided with between guiding core 6 and fairlead 7, the top, upper end of guiding core 6 is pressed in the lower end of transition connecting rod 3, the lower end of guiding core 6 is pierced in the guide through hole of fairlead 7, the upper end of fairlead 7 is threaded with the lower end of exterior lock tube 4, the lower end of fairlead 7 is provided with external screw thread.Stage clip 5 pairs of plugs 1 support and locate, and fairlead 7 lower thread is convenient to connect with the connecting rod on equipment, and certain those skilled in the art also according to concrete equipment, can use other connected mode, as axial pin type, buckle-type etc.
Preferably, transition connecting rod 3 and plug 1 junction are provided with stop nut 2.Stop nut can be locked transition connecting rod 3 and is connected with plug 1, more reliably.
During work, after being in place, start compacting, upper stamping press overcomes the support force of stage clip 5, and plug 1 is moved down, and realizes compacting of floating; After plug 1 floats a segment distance, the lower surface of stop nut 2 contacts with the upper surface of exterior lock tube 4, and restriction plug 1 continues to move down, and realizes plug location.After having suppressed the demoulding, plug 1, under the spring-force driven dual of stage clip 5, above moves on to initial position, prepares the circulation of next compacting.
The utility model structure is simple, reliable, and on the press device of common compact, realize compacting of floating, good product quality, dimensional accuracy is high, reduces mould and equipment cost.
Certainly; the utility model also can have other various embodiments; when not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art are when making various corresponding change and distortion according to the utility model, but these change accordingly and are out of shape the protection domain that all should belong to the claim appended by the utility model.
