A kind of bending mould core rod with interconnection system slide core pearlTechnical field
The utility model is related to auto parts and components manufacturing, specifically a kind of bending die with interconnection system slide core pearlPlug.
Background technology
Pipe bending technique is widely used in boiler and pressure vessel industry, central air-conditioning manufacturing industry, auto industry, Aero-SpaceA variety of industries such as industry, shipping industry, the quality of bending quality, will directly influence these industries product it is rational in infrastructureProperty, security, reliability etc.；Therefore, in order to bend out high-quality pipe fitting, pipe fitting should just be grasped under different technology conditionsFinishing technique；For cold conditions bend pipe, the formation of reasonable selection plug and to grasp its correct application method very necessary.
It is so-called to have core bend pipe, exactly as the pipe relative bending radius R/D or relative wall thickness S/D smaller bent, beThe high-quality pipe fitting of acquisition, during pipe is bent, inserts suitable plug, to prevent pipe curved inside itCircular arc occurs becoming flat and wrinkling method when bent.
Because rigidity is strong during existing bend pipe plug bend pipe, in the big position of bend pipe angle, it is difficult to ensure that the deflection of pipe；And raw material expend big, it is impossible to safeguard, scrappage is high.
Utility model content
The purpose of this utility model is to provide a kind of bending mould core rod with interconnection system slide core pearl, above-mentioned to solveThe problem of being proposed in background technology.
To achieve the above object, the utility model provides following technical scheme：
A kind of bending mould core rod with interconnection system slide core pearl, including the bending mould core rod with interconnection system slide core pearlBody；The bending mould core rod body with interconnection system slide core pearl is by core pearl, slide core pearl, connector, core folder, hingeChain, plug composition；Its SMIS pearl is plugged on inside connector；Tail end outside groove, connector is provided with inside the slide core pearlProvided with boss, connector runs through slide core pearl, and the boss of connector is connected to the groove of slide core pearl；The core folder is by straight-barConstituted with intermediate plate, intermediate plate be by two it is hemispheric constitute, intermediate plate is connected by hinge with straight-bar, and intermediate plate lateral wall is provided with spiral shellLine, the other end of connector is connected in the intermediate plate of core folder；The madial wall of the plug is provided with screw thread, the folder that its specification is pressed from both sides with corePiece external screw thread is identical, and core folder is connected through a screw thread installed in the inside of plug, so that connector is locked in the intermediate plate that core is pressed from both sidesPortion；Install more convenient；When needing repairing or changing product, as long as core folder, which is exited, can just change slide core pearl, connector, corePearl, it is more convenient quick.
It is used as further program of the utility model：It is hollow inside the plug, saves material, and quenchPlate hard Cr processing in HRC30-32, surface.
It is used as the utility model further scheme：The slide core pearl quenches HRC30-32, and hard Cr processing is plated on surface.
It is used as the utility model further scheme：The connector quenches HRC30-32, and hard Cr processing is plated on surface.
It is used as the utility model further scheme：The core folder quenching HRC30-32, hard Cr processing is plated on surface.
It is used as the utility model further scheme：The core pearl quenches HRC30-32, and hard Cr processing is plated on surface.
Compared with prior art, the beneficial effects of the utility model are：
1. greatly reducing the input of raw material, cost is reduced；
2. improving the deflection of bend pipe, 360 degree of rotations can be accomplished in tube interior；
3. being easy to mode transfer to safeguard, mould scrappage is reduced.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried outClearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than wholeEmbodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is madeThe every other embodiment obtained, belongs to the scope of the utility model protection.
Refer in Fig. 1~6, the utility model embodiment, a kind of bending mould core rod with interconnection system slide core pearl, wrapInclude the bending mould core rod body with interconnection system slide core pearl；The bending mould core rod body with interconnection system slide core pearl isIt is made up of core pearl 1, slide core pearl 2, connector 3, core folder 4, hinge 5, plug 6；Its SMIS pearl 1 is plugged on inside connector 3；InstituteState the inside of slide core pearl 2 and be provided with groove, the outside tail end of connector 3 is provided with boss, and connector 3 runs through slide core pearl 2, connector 3Boss be connected to the groove of slide core pearl 2；The core folder 4 is made up of straight-bar and intermediate plate, and intermediate plate is hemispheric by twoConstitute, intermediate plate is connected by hinge 5 with straight-bar, intermediate plate lateral wall is provided with screw thread, the other end of connector 3 is connected to core folder 4In intermediate plate；The madial wall of the plug 6 is provided with screw thread, and its specification is identical with the intermediate plate external screw thread that core presss from both sides 4, and core folder 4 passes through screw threadConnection is installed in the inside of plug 6, so that connector 3 is locked inside the intermediate plate that core presss from both sides 4；Install more convenient；Need dimensionIt is more convenient quick as long as core folder 4, which is exited, can just change slide core pearl 2, connector 3, core pearl 1 when repairing or changing product.
The inside of plug 6 is hollow, is saved material, and quenches HRC30-32, and hard Cr processing is plated on surface.
The slide core pearl 2 quenches HRC30-32, and hard Cr processing is plated on surface.
The connector 3 quenches HRC30-32, and hard Cr processing is plated on surface.
