Specific implementation mode
In order to make those skilled in the art more fully understand the technical solution of the utility model, below in conjunction with the accompanying drawings and have
The utility model is described in further detail for body embodiment.
Fig. 1, Fig. 2, Fig. 3 show that a kind of 6 shaping mould of steel pipe, including clamping 1 and plug 2, the clamping 1 include band sliding slot
111 and the upper mold 101 and lower die 102 that are oppositely arranged, the upper mold 101 and lower die 102 are removably to be combined with each other, institute
It states 101 sliding slot 111 of upper mold and 102 sliding slot 111 of lower die constitutes the shaping hole 11 for accommodating steel pipe 6,11 front end of shaping hole is for core
Stick 2 is inserted freely into, and its rear end is installed with the backstop 3 for preventing steel pipe 6 to be detached from, and the plug 2 can enter along shaping hole 11
The inner cavity of steel pipe 6 and coordinate shaping hole 11 to steel pipe 6 carry out shaping.
As shown in Figure 1, Figure 3, upper mold 101 includes upper die holder and the upper internal model on upper die holder, lower die 102 include
Lower die holder and the core insert on lower die holder, upper die holder and lower die holder are fixed in equipment, and upper internal model and core insert are to steel
Pipe 6 carries out shaping, and when die wear only needs to change internal model and core insert, without replacing entire mold, saves later stage batch
Die cost when production.
As shown in figure 3, clamping 1 is fixedly arranged at the front end with guide pad 4, the guide pad 4 has the pilot hole coordinated with plug 2
41, the plug 2 passes through the pilot hole 41 of guide pad 4 to enter in shaping hole 11.As shown in Figure 1, guide pad 4 is solid by screw
Dingan County is mounted in the front end of lower die 102.Pilot hole 41 on guide pad 4 remains when plug 2 can be made to be moved in shaping hole 11
Stablize.
As shown in Fig. 1, Fig. 3, Fig. 4, the backstop 3 is two pieces and is oppositely arranged up and down, is had on each backstop 3
The straight slot 311 axial along shaping hole 11, the edge of the straight slot 311 have the protrusion for extending and abutting steel pipe 6 to shaping hole 11
Portion 321, the straight slot 311 on two backstops 3 constitute removal hole 31, and the lug boss 321 on two backstops 3 constitutes flange collar 32.
With reference to figure 3, two pieces of backstops 3 are separately fixed at 102 rear end of 101 rear end of upper mold and lower die.Plug 2 enters from 11 front end of shaping hole
And shaping is carried out to steel pipe 6, for the port shaping for avoiding to steel pipe 6, plug 2 moves on until entering removal hole 31, plug
2,32 front end of flange collar and the cooperation of 1 inner wall of clamping influence product size to prevent the port shaping in reforming process.
This programme is the whole shaping to the especially shape tube of steel pipe 6, and plug 2 carries out shaping processing, clamping 1 to shape tube
Ensure that the appearance and size of product, guide pad 4 ensure that the center direction of advance of plug 2, backstop 3 ensure shape tube in process
In, clamping 1 will not be released by plug 2, plug 2, clamping 1, guide pad 4 and backstop 3 constitute an entirety, to irregular special-shaped
Pipe carries out shaping, and it is in rule state to make it, easy to process and use.Mold materials need to be the alternative materials of Cr12Mov or other
Material is heat-treated.It because shape tube may be stuck in the sliding slot 111 of lower die 102 after shaping, is not easily taken out, can separately take removal rod from tearing open
The inner cavity that shape tube is inserted at hole 31 is unloaded, to take out shape tube.
Upper mold 101 and lower die 102 are separately mounted to pipe end forming machine upper and lower part, have location hole 52 in upper mold 101,
The locating rod 51 coordinated with location hole 52 is fixed in lower die 102 (see Fig. 1).The left end of plug 2 and the piston rod of oil cylinder connect
It connects, right end passes through the pilot hole 41 of guide pad 4 to be plugged in shaping hole 11.
Reforming process is as follows：
When initial, upper mold 101 and lower die 102 are located at station and lower station, and the shape tube of shaping will be needed to be put into down
In the sliding slot 111 of mould 102.
(1) left part shaping：Start pipe end forming machine, upper mold 101 moves closer to finally be close to lower die 102, two pieces of backstops
3 also fit closely, and locating rod 51 is plugged in location hole 52 at this time.Then hydraulic oil cylinder driving plug 2 advances and enters shape tube
Inner cavity, plug 2 coordinate clamping 1 to carry out shaping to the tube wall of shape tube, and it is in rule state to make it, and backstop 3 prevents plug 2 from being pushed away
Go out clamping 1.Then oil cylinder cored bar 2 leaves the inner cavity of shape tube.Upper mold 101 leaves lower die 102 and returns to station later.
(2) right part shaping：The left and right end of shape tube is exchanged, then repeatedly step (1), realizes shape tube right half
Shaping finally takes out the shape tube that shaping is completed from the sliding slot 111 of lower die 102.
Above embodiment does not constitute the restriction to the technical solution protection domain, any in the above embodiment
Spirit and principle within made by modifications, equivalent substitutions and improvements etc., should be included in the technical solution protection domain it
It is interior.
