Abstract
The invention discloses a method for manufacturing a bent pipe. The method comprises the following steps: 1) selecting a metal pipe according to the size and shape of the bent pipe, and deburring until the surface is smooth; 2) placing the metal pipe obtained by the step one on a lower die of a moulding die, and moving an upper die downward to assembly the die; 3) plugging the two ends of the metal pipe by virtue of a mandrel and sealing, and injecting a liquid into the metal pipe from a through hole on the mandrel by virtue of a power device, thus the metal pipe is filled with the liquid and can maintain pressure which is enough to support bending moulding; 4) starting a bending die to carry out bending moulding on the metal pipe filled with the liquid; and 5) resetting the bending die, and moving the upper die upward to take out products. The method disclosed by the invention has the advantages of simple production process, high working efficiency, and no harm and pollution to a human body and environment in the production process; and the pipe walls of the products produced by the method disclosed by the invention are consistent, the appearances of the products are beautiful, the surface of the product is provided with no bump or wrinkle, and the product quality is high.
Description
Technical field
The present invention relates to a kind of preparation method of bend pipe.
Background technology
In the past, for metal pipe material is carried out brake forming, normally earlier toward solid material such as the interior filling sand of tubing, lead, alum, again to its brake forming, and then the filler in the tubing is flowed out metal pipe material heating, though make the purpose that can reach crooked in this way, there are many weak points in the bend pipe of making, cause etc. as: pipe fitting is uneven, not of uniform size, above-mentioned preparation method inefficiency, complex process, pollution are big simultaneously.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides that a kind of technology is simple, the preparation method of high efficiency, energy-conserving and environment-protective, product design is attractive in appearance, product percent of pass is high bend pipe.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of preparation method of bend pipe, this method comprises the steps:
1) selects metal pipe material according to size, the shape of bend pipe, and remove burr to smooth surface;
2) metal pipe material that step 1 is obtained is placed on the counterdie of mould, the descending matched moulds of patrix;
3) with the two ends of metal pipe material with push rod shutoff and sealing, toward metal pipe material in, inject liquid from the through hole on the push rod with power set, make the pressure of filling in the metal pipe material when expiring liquid and keeping enough support bends moulding;
4) start bending die the metal pipe material that is full of liquid is carried out brake forming;
5) bending die resets, and patrix is up can to take out product.
According to actual conditions, described metal pipe material is hollow metal T type pipe; Described metal pipe material also can be hollow metal Y-piece; Described metal pipe material can also be hollow straight tube or other hollow metal shaped tube; Described power set can be hydraulic pump, pulsometer or other power set that are fit to.
The invention has the beneficial effects as follows: production technology of the present invention is simple, high efficiency, production process can human body and environment work the mischief and pollute, meet national energy conservation and environment protection, in addition, consistent, the good looking appearance of producing by the present invention of product pipe walls size, the surface of product does not have concavo-convex and wrinkle, the product percent of pass height.
The specific embodiment
A kind of preparation method of bend pipe, this method comprises the steps:
1) selects metal pipe material according to size, the shape of bend pipe, and remove burr to smooth surface;
2) metal pipe material that step 1 is obtained is placed on the counterdie of mould, the descending matched moulds of patrix;
3) with the two ends of metal pipe material with push rod shutoff and sealing, toward metal pipe material in, inject liquid from the through hole on the push rod with power set, make the pressure of filling in the metal pipe material when expiring liquid and keeping enough support bends moulding;
4) start bending die the metal pipe material that is full of liquid is carried out brake forming;
5) bending die resets, and patrix is up can to take out product.
According to actual conditions, described metal pipe material is hollow metal T type pipe; Described metal pipe material also can be hollow metal Y-piece; Described metal pipe material can also be hollow straight tube or other hollow metal shaped tube; Described power set can be hydraulic pump, pulsometer or other power set that are fit to.
In addition, the present invention is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present invention with essentially identical means, all should belong to protection scope of the present invention.
