Abstract
The utility model relates to a flared type tightens up nut and pipe joint's binding off mould belongs to the mold design field. At present the fairway buoy flared type tightens up nut batch production on current phase, and product quality requirement is higher, can not with original mould part that takes shape, satisfy production progress and requirements for quality, and shaping product space afterwards can not be guaranteed, can take place defects such as skew, asymmetry. Consequently, to this mould redesign, lathe and mould form are used in the change, improve the part qualification rate, shorten production cycle, reduce workman's the operation degree of difficulty to reduce cost improves product quality.
Description
Technical field
This utility model belongs to Design of Dies field, tightens up the closing-in mould of nut and catheter adapter more particularly to a kind of flared type。
Background technology
Navigation mark flared type tightens up nut present stage and produces in batches, and product quality requires higher, with original die forming part, can not meet manufacturing schedule and prescription。Current frock adopts three times and closes up, product space after shaping it cannot be guaranteed that, it may occur that skew, the defect such as asymmetric。Punch ram is short, and active force is big, product local can be caused to have ripple, or have crackle, and the surface quality of part is defective。Mould structure is thin, and punch press pressure is big and effect is violent, and die life is short。Punch-die coordinates not compact, and after fillet part is stamping, deformation is uncontrollable, and the air-tightness of part does not reach requirement。Owing to closing in number of times is more, and workman need to manually locate part, and work danger coefficient is bigger。
Summary of the invention
Therefore this mould being redesigned, change uses lathe and die form, improves part qualification rate, shortens the production cycle, reduces the operation easier of workman, thus reducing cost, improves product quality。
A kind of flared type tightens up the closing-in mould of nut and catheter adapter, including die assembly, upper mould, keeper, slide plate, spacing collar, lower bolster, rubber, polyurethane elastomer, unloading bolt and guide pillar, upper mould is connected on spacing collar by unloading bolt and guide pillar, and the stroke of upper mould is limited by spacing collar and unloading bolt；Unloading bolt is through polyurethane elastomer, and described polyurethane elastomer is in the groove of upper mould and spacing collar；Die assembly and slide plate are connected with keyway by key and lead。
Hydraulic press drives upper mould to move down, and upper mould declivous cutting edge Extruding die assembly moves inward, and when upper mould moves to spacing collar, die assembly finally merges, and reaches closing in size；Hydraulic press moves up, and moves, be displaced outwardly at rubber effect lower cavity die assembly, complete the closing in of product under polyurethane elastomer effect on mould。Use this set frock, it is possible to one-time positioning part；Once-forming part；Part, holding parts is manuallyd locate without workman；Hydraulic press is compared with punch press, and active force is lasting, uniformly, so part forming quality is high, conforms to quality requirements。
This tool structure is simple, easy to operate, improves part closing in quality, shortens the production cycle, reduces the operation easier of workman, thus reducing cost, improves product quality。
Accompanying drawing explanation
Fig. 1 is the closing-in mould structural representation that a kind of flared type of the present utility model tightens up nut and catheter adapter。
Detailed description of the invention
Part HB4-49-4-2002 flared type is tightened up nut and HB-Z9C-5570-303 bent sub, after two kinds of part assemblings, is placed on keeper 3 from the opening part of upper mould 2；Upper mould 2 moves down compression polyurethane elastomer 8 with hydraulic press pressure handle effect, and guide pillar 10 leads；The declivous cutting edge of upper mould 2 contacts with die assembly 1, and continues to move down die assembly 1 and move to the inside along slide plate 4, and extrusion sections close up；Simultaneously along with die assembly 1 moves inward, rubber 7 is compressed；When upper mould 2 moves to spacing collar 5, die assembly 1 closes up。Moving on hydraulic press pressure handle, upper mould 2, by polyurethane elastomer 8 resilience, moves up, unloading bolt 9 controls displacement；Die assembly 1, with rubber 7 resilience, moves laterally along slide plate 4, spacing collar controls displacement, completes the closing in of part。
