Abstract
The utility model discloses a connect part. Present connect part structural style be 4 hole spiro union forms, and the connection form bearing strength is lower, simultaneously and relevant the joint use two sets of frocks to make the relevant frock clamp can not be general, be unfavorable for batch production, and connect part can use general frock clamp in follow -up welding process simultaneously, the frock clamp's of being convenient for commonality use, original structural stability is relatively poor, be 5 jogged joints through improving 4 jogged joints, has strengthened the stability behind the component assembly, intensity promote reach 25% reach more than, through connect part's configuration optimization, unify the part and connected the specification, the part batch production of being convenient for has reduced the parts machining cycle, has improved the wholeness that the part connects simultaneously, has guaranteed part requirements for quality, through part joint structural style's optimization, will connect the connection performance who has strengthened the joint and guarantee the part structure operation requirement.
Description
Technical field
The utility model belongs to 30CrMnSiA joint part architecture advances field, the 30CrMnSiA joint part related to is 1180 ± 100MPa for being heat-treated to intensity, improved by joint structure and joint is increased to 5 places by 4, the bearing capacity of this joint, stability and intensity are increased substantially.
Background technique
A kind of joint part involved by the utility model, be in particular 30CrMnSiA joint part, belonging to high tensile steel for being heat-treated to intensity is 1180 ± 100MPa, this aircraft joint part carries great alternate load, impulsive load and tension load, for improving tensility, corrosion resistance, the comprehensive mechanical property of joint part, have employed 30CrMnSiA stamp forgings and carry out global formation, ensure that the overall performance of joint part.But joint element joint is 4 holes to be spirally connected, 4 holes are spirally connected the most basic demand that can only ensure that part uses.By the improvement of joint element, joint is increased to 5 places by 4, not only increases the bearing capacity of joint part, join strength and stability will significantly improve, thus meet the usage requirement of part.
Concrete technological scheme is: part is integrated the plate that forging is formed, and plate face is irregular 5 limit shape shapes, and 5 angles of 5 limit shapes are rounding, and 5 roundings are of a size of R12mm, R13.5mm, R13.5mm, R13.5mm and R13.5mm; Each rounding part has the through hole of same size, and through-hole diameter is Φ 10mm; The zone line of 5 limit shapes has through hole, and through-hole diameter is Φ 44mm; The through hole of described zone line is eccentric opening.
Summary of the invention
1) goal of the invention
Aircraft joint part is 30CrMnSiA, and its manufacturing process adds-quench-tempering-welding for forging-machine.This type of joint part is given high tensile steel and is heat-treated to intensity is 1180 ± 100MPa, mainly carries great alternate load, impulsive load and tension load.Original joint connection manner is that 4 holes are spirally connected, and only ensure that the basic demand that part uses.
By the architecture advances of butt joint part, joint is increased to 5 holes by 4 holes, changes the shape of original attachment lug, improve the bearing capacity of joint part, join strength and stability, thus the usage requirement meeting part.
2) technological scheme
Joint part is the overall structure after forging, for irregular 5 limit shapes, different size angle is poured out at 5 edges of 5 limit shapes, and have corresponding 5 attachment holes, be divided into the 1st attachment hole, the 2nd attachment hole, the 3rd attachment hole, the 4th attachment hole, the 5th attachment hole, there is eccentric opening 6 (Fig. 2) in heart portion in the base.
3) beneficial effect:
Advantage of the present utility model:
The construction profile of butt joint part is optimized: original joint part structural type is that 4 holes are spirally connected form, now be improved to 5 holes to connect, original Connecting format bearing strength is lower, the great alternate load born for joint part, impulsive load can only reach Eligibility requirements, 5 hole Placements after improvement significantly improve join strength, ensure that part quality requirement; 4 holes connections simultaneously employ two cover frocks to relevant jointing, make relevant tool fixture can not be general, make frock obtain unified joint part simultaneously by 5 hole Innovation of Connections and can use general frock clamping in follow-up welding process, the versatility being convenient to frock clamping uses; Original structure stability is poor, by by 4 hole Innovation of Connections be 5 holes connect, strengthen the stability after Assembly of the parts, strength enhancing reach 25% and more than; By the structure optimization of joint part, unify joint element specification, be convenient to parts batch production, decreased the part process-cycle, improve the integrity of joint element simultaneously, ensure that part quality requirement; By carrying out rational architecture advances to existing joint part, the bearing capacity of this joint, stability and intensity are increased substantially and the part processed meets structural performance requirements, the part up-to-standard rate after improvement reaches 100%.

Embodiment
Be described in further detail with regard to the utility model structure below
Fig. 2 is shown in by part after the utility model optimization, heat-treats after the roughing of forging supplier, pays subsequent processing and weld after meeting the demands.
A kind of joint part, a particularly 30CrMnSiA joint part, described part is integrated the plate that forging is formed, and plate face is irregular 5 limit shape shapes, and 5 angles of 5 limit shapes are rounding, 5 roundings are of a size of R12mm, R13.5mm, R13.5mm, R13.5mm and R13.5mm; Each rounding part has the through hole of same size, and through-hole diameter is Φ 10mm; The zone line of 5 limit shapes has through hole, and through-hole diameter is Φ 44mm; The through hole of described zone line is eccentric opening.
Described small through hole is attachment hole.
It uses step as follows:
1st attachment hole, pore size is
10H7 is interference when preventing from connecting between screw and part, special hole 1 and axis of workpiece is offset 7 °, can meet the machining needs of part.
2nd attachment hole, the 3rd attachment hole and joint base eccentric opening 6.2nd attachment hole and the 3rd attachment hole are evenly distributed on axis of workpiece both sides respectively, and pore size is
10H7, can meet again the machining needs of part while that this position meeting the maximum Containing size of this forging.
By the 4th attachment hole, the 5th attachment hole.4th attachment hole and the 5th attachment hole are distributed in axis of workpiece both sides respectively, and hole size is
10H7, for avoiding the screw in assembling and part to interfere, hole 4 and hole 5 asymmetric distribution, be specifically shown in Fig. 2, be ensure that effective connection of part by two hole sites that reasonably distribute.
