Part, the effect serve shunting, confluxing.
As Figure 2-Figure 5, this utility model embodiment additionally provides a kind of punching press three-port structure processing method, including step
Rapid:
S1: select blank to obtain the pipe of fixed length；
Wherein, a diameter of D of pipe0, the wall thickness of pipe is t0.The pipe obtaining fixed length can pass through chipless blanking, it is possible to
With by artificial cutting etc..
S2: one end of pipe is carried out spinning enlarging so that one end of pipe forms flared end；
Wherein, a diameter of D, the D ＞ D of flared end0.The other end of pipe is the total pipe jointing part connecting house steward, flared end
Connecting branch.
S3: flared end is slightly rushed so that the part-structure of flared end forms slab construction.Wherein, thick punching is for expansion
Mouth end carries out first step punching operation.
As shown in Figure 4, illustrating with the embodiment that manifold size is identical, the structure of i.e. two pipe jointing parts 1 is identical.
Therefore, in step 3, after flared end is slightly rushed, two slab constructions being parallel to each other are formed.Two slab constructions same
Side is respectively connected with semi-circular plate, forms the structure being similar to runway.
Wherein, the height H=d+2t of the flared end after thick punching, wherein, the wall thickness of flared end when t is this structure, t is less than
t0。
S4: carefully rush flared end, processes stamped groove 2 in slab construction, and stamped groove 2 is " V " shape groove, flared end position
Part in the centrage both sides of stamped groove 2 forms a pipe jointing part 1.That is, stamped groove 2 intersected by two pipe jointing parts 1 and
Become.Wherein, carefully rush as flared end is carried out second step punching operation.
In step S4, insert core bar in flared end, then in flared end, process stamped groove 2.By inserting in flared end
Core bar, it is ensured that the Internal periphery size of a pipe jointing part 1 after processing stamped groove 2, improves machining accuracy.Wherein, the chi of core bar
Very little identical with a manifold size that pipe jointing part 1 needs connect, and, the core bar quantity that flared end is inserted is two.
As it is shown on figure 3, in step S2, the external diameter of flared end is D；As it is shown in figure 5, in step S4, two pipe jointing parts 1
Formation is similar to the cross section of " 8 ", the outline Zhou Changwei S of this cross section.Wherein, the span of π D=S-S ', S ' be 1～
3mm.That is, the flared end in Fig. 3 is after thick punching (step S3) and thin punching (step S4), forms the structure in Fig. 5, its outer wall
Circumferential deformation amount be the span of S ', S ' be 1～3mm.It follows that reduce Pressing Deformation amount further.
