Abstract
The invention discloses a kind of titanium and thin-wall stainless steel corrugated pipe forming method, comprise the following steps: titanium and thin-wall stainless steel bellows are put into shaping die, described titanium and thin-wall stainless steel bellows wall thickness are less than 3mm, described shaping die comprises patrix, intermediate die, counterdie, described intermediate die comprises middle punch and middle die, described middle die adopts polymer rubber material cushion block, the circumferentially employing 3-8 block polymer rubber material cushion block of each ripple forming; Titanium and thin-wall stainless steel ripple pipe are exerted pressure, suppresses to rubber cushion blocks deformation retract 1/4-2/5.The present invention's polymer rubber material cushion block replaces conventional metal and plays drum mat block, improves the conformity of metal bellows wave height, reduces or eliminates the unstable phenomenon in metal bellows forming process, thus improves quality and the life cycle of metal bellows.
Description
Technical field
The present invention relates to metal and manufacture the forming method that field, particularly material are titanium and thin-wall stainless steel bellows.
Background technique
Metal bellows is for compensating the additional stress caused because of temperature difference and mechanical vibration and a kind of flexible structure be arranged on container shell or pipeline, has the advantages such as reliable operation, functional, compact structure.As sensing element, damper element, compensating element and pipe joint, be widely used in the fields such as automatic control and measurement instrument, vacuum technique, mechanical industry, power industry and atomic energy industry.
Titanium and thin-wall stainless steel bellows utilize upper die and lower die, intermediate die (intermediate die comprises middle punch and middle die), then titanium and thin-wall stainless steel ripple pipe pressure-bearing, makes titanium and thin-wall stainless steel pipe at the correction compacted under bellows of mould.In actual production, the wave height conformity of titanium and thin-wall stainless steel bellows is bad, and the yield strength as titanium material is large, after having suppressed drum, pipe outer wall can not engage closely with the inwall of middle die, in the middle of removing after die (metal plays drum mat block), causes middle punch card incessantly to move down; Titanium and thin-wall stainless steel (δ≤3mm) are often thin because playing the rear pipe of drum, and without enough support forces, holder incessantly intermediate die causes middle punch to move down.
Summary of the invention
The present invention, for solving the deficiencies in the prior art, provides a kind of titanium and thin-wall stainless steel corrugated pipe forming method.
The present invention is by the following technical solutions:
A kind of titanium and thin-wall stainless steel corrugated pipe forming method, comprise the following steps:
Step 1, titanium and thin-wall stainless steel bellows are put into shaping die, described titanium and thin-wall stainless steel bellows wall thickness are less than 3mm, described shaping die comprises patrix, intermediate die, counterdie, described intermediate die comprises middle punch and middle die, described middle die adopts polymer rubber material cushion block, the circumferentially employing 3-8 block polymer rubber material cushion block of each ripple forming;
Step 2, titanium and thin-wall stainless steel ripple pipe to be exerted pressure, suppress to rubber cushion blocks deformation retract 1/4-2/5.
Further, described polymer rubber material cushion block upper and lower end face tilts to titanium and thin-wall stainless steel bellows core, and wherein angle of inclination is 5-10 °.
Further, described polymer rubber material cushion block is that to be become by polymer rubber linear cutter thick for 20-50mm be highly the polymer rubber material cushion block of 80 ~ 150mm.
Further, described polymer rubber is styrene butadiene rubber, butadiene rubber, isoprene rubber, isopropyl rubber, neoprene or nitrile butadiene rubber.
Further, the circumferentially employing 3-8 block polymer rubber material cushion block of each ripple forming, overall width covers 50-75% circumference.
Further, described titanium and thin-wall stainless steel bellows wall thickness are 1.5-2.5mm.
Further, described polymer rubber material cushion block is that to be become by polymer rubber linear cutter thick for 30-40mm be highly the polymer rubber material cushion block of 100 ~ 150mm.Beneficial effect of the present invention: the present invention's polymer rubber material cushion block replaces conventional metal and plays drum mat block, improve the conformity of metal bellows wave height, reduce or eliminate the unstable phenomenon in metal bellows forming process, thus improving quality and the life cycle of metal bellows.

Fig. 1 is the schematic diagram after putting into polymer rubber material cushion block;
Fig. 2 is the schematic diagram after exerting pressure to Fig. 1;
Fig. 3 is that Fig. 2 rolls over the schematic diagram after except polymer rubber material cushion block;
Fig. 4 is the schematic diagram being depressed into specified altitude assignment after Fig. 3 places internal formed block.
Embodiment:
Below in conjunction with embodiment and accompanying drawing the present invention done and further explain.
A kind of titanium and thin-wall stainless steel corrugated pipe forming method, comprise the following steps:
Step 1, titanium and thin-wall stainless steel bellows 6 are put into shaping die, described titanium and thin-wall stainless steel bellows 6 wall thickness are less than 3mm, and described shaping die comprises patrix 1, intermediate die, counterdie 2, and described intermediate die comprises middle punch 3 and middle die 4.Described middle die 4 adopts polymer rubber material cushion block, and there is inclined-plane upper and lower end face slightly, centroclinal 6 ° to metal bellows, this inclined-plane, is outwards out of shape when metal bellows is shaping during cushion block distortion.Circumferentially employing six pieces of polymer rubber material cushion blocks of each ripple forming, can hold middle punch mold, the indeformable contraction of block rubber is as the criterion;
Step 2, suppress to rise drum pressure after, according to a conventional method titanium and thin-wall stainless steel ripple pipe 5 are exerted pressure, suppress to rubber cushion blocks deformation retract 1/3.
Polymer rubber material cushion block of the present invention is that to be become by polymer rubber linear cutter thick for 20-50mm be highly the polymer rubber material cushion block of 80 ~ 150mm, is highly preferably the polymer rubber material cushion block of 100 ~ 150mm by polymer rubber linear cutter thick for 30-40mm one-tenth.The corrugated pipe wall of corresponding different-thickness, end face is neat, and depth-width ratio is that 3:2 is suitable for, and material therefor thickness is even, error≤1mm.
Polymer rubber of the present invention adopts synthesis or Natural rubber sheet, as styrene butadiene rubber, butadiene rubber, isoprene rubber, isopropyl rubber, neoprene or nitrile butadiene rubber.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
