Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figs 1-4.
A kind of seamless dislocation four-way one-shot forming apparatus, it include it is cold push away machine and molding die, it is cold push away machine a left side be installed push away
First 3 and right push top 4, left push top 3 and right 4 both ends respectively with former material pipe fitting 7 of push top offset, the center of left push top 3 and right push top 4
Be respectively equipped with for medium 8(water) enter central through hole, each central through hole is mounted on corresponding left check valve 5 and the right side is unidirectional
Valve 6, as shown in Figure 1, the mold includes upper mold 1 and lower die 2, upper mold 1 and lower die 2 form the peace of former material pipe fitting 7 after molding
Space is filled, upper mold 1 is identical with the structure of lower die 2, they are equipped with an axial keyway, installs respectively at the both ends of axial keyway
The left jacking block 10 of pectination and the right jacking block 12 of pectination are equipped in the axial keyway between the left jacking block 10 of pectination and the right jacking block 12 of pectination
Pectination insert 11, the left jacking block 10 of the pectination, the right jacking block 12 of pectination do not slide, and pectination insert 11 can be in axial keyway with original
Material pipe be squeezed the branch pipe preliminarily formed slide into left jacking block coincide, stroke terminates, branch pipe molding.Pectination insert 11
Comb teeth direction is vertical with the comb teeth direction of the left jacking block 10 of pectination and the right jacking block 12 of pectination, such as Fig. 3.In upper mold 1 and lower die 2 with original
Material pipe fitting 7, which need to be formed at branch pipe position, is respectively provided with a mouth of pipe 9, and former material pipe fitting 7 is pushed away in the axial direction of left push top 3 and right push top 4
Under power and the effect of the radial thrust of medium 8, the bulge as branch pipe is formed in mouth of pipe 9.It is cold to push away the left push top 3 of machine and cold push away machine
It is right push top 4 work while, by left check valve 5 into former material expects pipe 7 pumped (conveying) medium water, caused by pressure pass through upper and lower mould
On mouth of pipe 9 form branch pipe.Pectination insert 11 is slided in branch pipe forming process with the sliding of raw material, and branch pipe is made
Compensation uniformly, prevents pipe fitting cracking, branch pipe eccentric.The left jacking block 10 of pectination insert 11, pectination and the right jacking block 12 or so of pectination cooperate,
Tube body can be also supported while can slide, the gap of pectination cooperation is insufficient to allow tube body to deform.The left jacking block 10 of pectination and comb
Shape insert 11, which matches, is overlapped mouth of pipe, guarantees branch pipe compact dimensions precision.It is cold to push away machine by left check valve 5 to former material expects pipe
Pumped (conveying) medium pressurizes in 7；When hypertonia, pass through right 6 pressure release of check valve.It is pressurised into formation of tubes and power is provided, pressure release guarantees
Overpressure is up to standard, prevents pressure is excessive from causing supervisor and branch pipe cracking.The mouth of pipe that pectination insert 11 is contacted with former material expects pipe 7
Locate rounded corner, can also prevent mold from damaging to pipe while fixed manifold size.It is calculated before formation of tubes former
The distance of the molding displacement of tubes of material 7, so that it is determined that the size of pectination insert 11.The left jacking block 10 of pectination and the right jacking block 12 of pectination are divided
It is not overlapped with the end face of lower die 2, so that it is determined that the stroke of the right jacking block 12 of pectination, i.e. branch pipe stroke.
The application method of the utility model is:
Firstly, before the seamless one-time formed device of dislocation four-way with the utility model is formed, it should be according to mark
Quasi- and practical experience terminates the displacement of state to calculate former material expects pipe 7 from reset condition to pushing, determines that lower die is combed with this
The stroke of shape insert 11, and as Reference Design mold.The placement location of mold and former material expects pipe 7 is adjusted before molding, this
The state of Shi Yuancai expects pipe 7 as shown in Fig. 2 first state, comb as shown in Fig. 4 reset condition at position 1 for lower die by mold state
Shape insert 11 and the right jacking block 12 of lower die pectination match, and two mouth of pipe are staggered at position 2,11 He of lower die pectination insert at position 3
The left jacking block 10 of lower die pectination is staggered, prevents in forming process because mold blank deforms supervisor；Machine 3 Hes of left push top are pushed away cold
Cold while push away machine 4 pairs of former material expects pipes 7 of right push top and carry out pushing, medium water is entered by left check valve 5 (can also be from right list in pipe
To valve 6 into left check valve 5 goes out), and start to apply pressure, the pressure of water passes tubulars through the branch pipe at lower die pectination insert 11
Mouth forms bulge, as shown in Fig. 4 bulge formation state；When left and right, which is had a haircut, continues pushing, former material expects pipe 7 is subjected to displacement, and under
Mould pectination insert 11 is displaced with former material expects pipe 7 and branch pipe bulge is driven to be displaced, and supervisor back and long axis shoulder can in this way
To compensate branch pipe in time, its cracking and bias are prevented；When overpressure is excessive, pressure release can also be carried out by right check valve 6, prevented
Only because pressure it is excessive caused by be responsible for craze and transfiguration；As shown in figure 4, at the end of 11 stroke of lower die pectination insert, with lower die pectination
Left jacking block 10 matches, and two mouth of pipe coincide at position 2 as shown in Figure 4, determines branch pipe position, and lower die pectination is inlayed at position 3
Block 11 and the right jacking block 11 of lower die pectination are staggered, prevent because mold blank deforms supervisor, after keeping constant pressure at this time, such as
Shown in Fig. 2, branch pipe molding.
The parts not involved in the utility model is the same as those in the prior art or can be realized by using the prior art.
