Its technical scheme is: a pipe throat ware for press, include extension board down, stud, a spring, the guide pillar, the guide pin bushing, the lower mould, go up the mould, take off the plumber block, countersink bolt, go up extension board and gag lever post, be equipped with the guide pillar down on the extension board, the guide pillar is lived with the guide pin bushing and is joined in marriage, the spring pressure equipment is between the lower terminal surface of the boss of guide pillar and guide pin bushing, the guide pin bushing is lived with the lower mould and is joined in marriage, the lower mould passes through stud and the extension board is solid as an organic whole down, it is solid as an organic whole with last extension board that last mould passes through countersink bolt, it sets up the hole upper end at last mould with the prescription formula of living to take off the plumber block, the hole lower extreme of going up the mould be equipped with with the work piece throat after the external diameter throat die cavity of living and joining in marriage, the lower extreme of throat die cavity be equipped with with the work piece throat before the external diameter guide mouth of living and joining in marriage, the gag lever post passes the lower mould with the prescription formula of living after, its upper end and last mould rigid coupling. The beneficial effects are that: simple structure, convenient operation, changeable by draw spare, even by necking down portion atress, the throat is of high quality, and is efficient.
Description
Technical field
The utility model relates to a kind of forcing press pipe reduced mouth part, belongs to mechanical pressure processing technique field.
Background technology
In mechanical pressure processing, often to carry out reducing or the enlarging of various pipe component, when tube length is no more than 250mm and its diameter is less, reducing can be carried out with process for stamping on punch press, when tube length is more than 250mm, again without special equipment, punch press is because being subject to the restriction of its shut height just helpless, but now can consider to carry out reducing on forcing press, because the shut height of forcing press is large, haul distance is long, but carry out pipe reducing with forcing press and must have a set of necking die, because there is no reducing die, this reducing mode just cannot have been carried out.
Summary of the invention
The purpose of this utility model is just to provide a kind of forcing press pipe reduced mouth part, for solving the problem.
The technical solution of the utility model is: a kind of forcing press pipe reduced mouth part, comprise lower carrier plate, stud, spring, guide pillar, guide pin bushing, counterdie, patrix, de-plumber block, dormant bolt, upper supporting plate and gag lever post, lower carrier plate is provided with guide pillar, guide pillar and guide pin bushing are lived and are joined, pressure mounting of the spring is between the boss and the lower surface of guide pin bushing of guide pillar, guide pin bushing and counterdie are lived and are joined, counterdie is solidified as a whole by stud and lower carrier plate, patrix is solidified as a whole by dormant bolt and upper supporting plate, de-plumber block is arranged on the endoporus upper end of patrix with formula formula of living, the endoporus lower end of described patrix be provided with workpiece reducing after external diameter to live the reducing die cavity of joining, the lower end of described reducing die cavity be provided with workpiece reducing before external diameter to live the guiding port of joining, after gag lever post passes counterdie with formula formula of living, its upper end and patrix affixed.
The beneficial effects of the utility model are: structure is simple, easy to operate, changeable by draw part, and necking portion uniform force, reducing quality is good, and efficiency is high.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, known with reference to accompanying drawing 1, a kind of forcing press pipe reduced mouth part, comprise lower carrier plate 1, stud 2, spring 3, guide pillar 4, guide pin bushing 5, counterdie 7, patrix 8, de-plumber block 9, dormant bolt 10, upper supporting plate 11 and gag lever post 12, lower carrier plate 1 is provided with guide pillar 4, guide pillar 4 is lived with guide pin bushing 5 and is joined, spring 3 is fitted between the boss of guide pillar 4 and the lower surface of guide pin bushing 5, guide pin bushing 5 is lived with counterdie 7 and is joined, counterdie 7 is solidified as a whole by stud 2 and lower carrier plate 1, patrix 8 is solidified as a whole by dormant bolt 10 and upper supporting plate 11, de-plumber block 9 is arranged on the endoporus upper end of patrix 8 with formula formula of living, the endoporus lower end of described patrix 8 be provided with workpiece 6 reducing after external diameter to live the reducing die cavity of joining, the lower end of described reducing die cavity be provided with workpiece 6 reducing before external diameter to live the guiding port of joining, after gag lever post 12 passes counterdie 7 with formula formula of living, its upper end and patrix 8 affixed.When using the utility model to carry out pipe reducing, first upper supporting plate 11 of the present utility model and lower carrier plate 1 bolt are separately fixed on the lower work platform of forcing press, starting pressure machine, upper table makes drawback movement, when moving in limited time, the utility model is in opening, now guide pin bushing 5 is in extreme higher position by the tension force effect of spring 3, can feed, when filling with substance, workpiece 6 exceeds guide pin bushing 5 upper surface 10mm guide pin bushing 5 planted agent and leads as upper and lower mould, consider the swollen thick discharging convenience factor of workpiece 6 in reducing process, workpiece 6 and guide pin bushing 5 inner chamber stay 0.5mm gap in diametric(al), during the draw, first workpiece 6 targeting part enters in the guiding port of patrix 8, then its reducing die cavity is entered, when patrix 8 moves to minimum point, reducing process completes, when the upper table of forcing press is up to a certain position, workpiece 6 is got and is come off by de-plumber block 9, whole reducing operation terminates.
