Abstract
The utility model provides an automobile -used braking or separation and reunion for hose nipple bundy pipe bulge and seal fixed knot and construct, includes bundy pipe (1) and joint pipe box (2), and bulge (5) including bundy pipe lining core (3) and bundy pipe (1), and joint pipe box (2) is fixed and is located characterized by in bundy pipe swell (5) bundy pipe serves as a contrast core (3) attachment plug pipe box (2), with press fitting die (9) crimp contact pipe box (2) with bundy pipe bulge (5) with connect pipe box (2) the sealing connection that fuses. This automobile -used braking or separation and reunion for hose nipple bundy pipe bulge and seal fixed knot and construct adopt the mould pressing method with metal joint pipe box pressfitting to the bundy pipe swell. Extrude into swell and one section 1 -3mm reducing changeover portion of requirement with bundy pipe through the cold extrusion method, simultaneously, adopt toper pressfitting ring method with metal joint pipe box pressfitting to the bundy pipe swell to solved bundy pipe and the easy rotation of pipe box pressfitting department, the scheduling problem is easily revealed down to the high pressure.
Description
Technical field
The utility model relates to vehicle component field, is that in automobile-used braking or clutch system pipeline, metal connectsA kind of structure and the processing mode of head, specifically Bandaid pipe bulge for a kind of automobile-used braking or clutch hose couplingWith sealing fixed structure.
Background technology
Along with the high speed development of Chinese Automobile Industry ', oneself becomes one of important vehicles of people automobile, andBraking or clutch system are that automobile slows down and the requisite important spare part of clutch while running, are also importantSafety member, performance quality is directly connected to the person and property safety is vehicle key parts.
Domestic automobile-used vehicle braking hose and clutch tube joint with Bandaid pipe substantially all adopts welding at presentMode or split type pressing structure. Adopt welding manner to connect Bandaid pipe and metal joint pipe box, this sideWhen method exists welding, damage Bandaid tube-surface coating, connector is surface treatment and the difficult control of weld strength againEtc. problem; Adopt lining core to be welded to pipe box rear sleeve and press to the split type pressing structure on Bandaid pipe, BandaidPressing place of tube and tube cover is easily rotated, the easy problem such as leakage under high pressure.
Summary of the invention
The purpose of this utility model is to provide a kind of automobile-used braking or clutch hose coupling Bandaid pipe bulge and closeSealing fixed structure, to solve, automobile-used braking or pressing place of clutch hose coupling Bandaid tube and tube cover are easily rotated, heightDepress the problems such as easy leakage.
The purpose of this utility model can reach by following measures:
The bulge of Bandaid pipe and sealing fixed structure for a kind of automobile-used braking or clutch hose coupling, comprise Bandaid pipe 1With joint pipe box 2, Bandaid pipe 1 comprises Bandaid pipe lining core 3 and Bandaid pipe bulge 5,Joint pipe box 2 is fixed on Bandaid pipe bulge 5 places, and described Bandaid pipe lining core 3 inserts joint pipe box 2, uses pressingMould 9 squeezed joint pipe boxes 2 are connected Bandaid pipe bulge 5 to be tightly connected with joint pipe boxes 2.
Described Bandaid pipe bulge 5 and Bandaid pipe lining core 3 be push by draw extrusion die 8 and clamping die 7 andBecome.
Described Bandaid pipe bulge 5 has one section of 1-3mm reducing changeover portion 4.
Described joint pipe box 2 is provided with taper pressing ring 6 with Bandaid pipe bulge 5 links.
The beneficial effects of the utility model are:
The utility model adopts mould pressing method squeezed joint pipe box that the bulge of Bandaid pipe and joint pipe box are linked to be to oneBody, has reached air-brake coupling hose or clutch tube hot strength is greater than 1500N standard-required; Meanwhile, jointBulge place of end Bandaid pipe adopts 1-2mm reducing excessively and adopts taper pressing ring mode, has solved Bandaid pipeEasily rotate the easy problem such as leakage under high pressure with pipe box pressing place.
