Abstract
The present invention relates to a diameter reducing processing method for metal pipes. The method comprises that a metal pipe is cut into a metal pipe with required specifications, and diameter reducing processing is carried out. The present invention is characterized in that a metal pipe is fixed in a clamping device, and a pressing machine is provided with a diameter reducing mold of which the diameter is corresponding to the pipe diameter of the metal pipe; the pressing machine is operated to press the end of the metal pipe. As mold opening-compression processing is carried out on the metal pipe, a thick metal wall layer is formed at the diameter reducing part under the extruding action of the mold, and accordingly, the phenomenon that the diameter reducing part is broken when the metal pipe is lathed can not occur. The present invention has the advantages of good processing quality, high processing speed, and simple processing machines.
Description
Technical field:
The present invention relates to the metal tube processing technique field, particularly a kind of metal tube reducing method for processing.
Background technology:
At present, the general method of spinning that adopts of metal tube reducing processing is made.A kind of " a metal-pipe spinning system machine " just disclosed for No. 96202992.0 as Chinese patent.Adopt the method for spinning to carry out reducing, can cause the tube wall of choke thinner, when metal tube is carried out processing of car system and use, all be prone to the choke fracture.Moreover, adopt the method for spinning that metal tube is carried out reducing processing, be difficult to choke is made the reducing of specific (special) requirements such as rectangle, polygon.And use spin-on process that metal tube is carried out reducing, its process velocity is slower.In metal tube reducing processing technology, also have a kind of butt-joint technology, its choke that casting is formed is connected on the metal tube by the method for butt-joint, and its weld part of reducing metal tube of this kind method processing is easy to crack, and process velocity is also slower.
Summary of the invention:
For solving metal tube choke easy fracture, the defective that process velocity is slow.The inventor provides a kind of choke to connect diameter reducing working method for metal pipe reliable, easy to process.It comprises: metal tube is cut into required specification, carries out reducing processing; It is characterized in that: metal tube is fixed in the clamping device, and forcing press is provided with and the corresponding reducing mould of metal tube caliber; The operating pressure machine is suppressed the metal tube end.Because metal tube is adopted mold pressing reducing processing, under the squeezing action of mould, choke forms thicker metal parietal layer, makes metal tube add man-hour carrying out car system, the choke phenomenon of rupture can not occur.Its crudy is good, process velocity is fast, and processing equipment is simple.
If need further to carry out reducing processing to metal tube, forcing press to be changed and the corresponding reducing mould of a preceding reducing metal tube, the operating pressure machine is suppressed once more to the metal tube end, and repeatable operation like this just can make the metal tube of required reducing.Diameter reducing working method for metal pipe also can carry out two terminations of metal tube reducing processing.
In the present invention, described reducing mould is some cover reducing moulds that internal diameter successively decreases.Use many cover reducing moulds the metal tube end can be dwindled step by step, metal tube is ruptured because of a reducing puts in place.Its reducing mould internal diameter decrement value difference of the metal tube of unlike material.The reducing mold sections can be one of them shape of interior circle, triangle, square, polygon.Different reducing mold sections can be made metal tube has difform reducing.
In the present invention, the metal tube of suppressing through reducing preferably carries out machined into, to reach the requirement of reducing.
Description of drawings:
Fig. 1 is the schematic diagram of device therefor of the present invention.
Fig. 2 is metal tube reducing process figure of the present invention.
Fig. 3 uses the metal tube through reducing that the present invention processes.
The specific embodiment:
As shown in Figure 1: the diameter reducing working method for metal pipe of present embodiment comprises: metal tube is cut into required specification, metal tube 1 is fixed in the clamping device 2, forcing press adopts hydraulic press, load onto on hydraulic press oil cylinder 3 and the corresponding reducing mould 4 of metal tube caliber, hydraulic press can be selected according to the concrete condition of metal tube.Suppress 5 pairs of metal tube ends of operation hydraulic press.Under the squeezing action of mould, choke forms thicker metal parietal layer 6, makes when metal tube carried out car system, the choke phenomenon of rupture can not occur.
Fig. 2 has provided metal tube reducing process of the present invention.When need carried out further reducing to metal tube 1, hydraulic press was changed and the corresponding reducing mould 4 of a preceding reducing metal tube, and the operation hydraulic press is suppressed once more to the metal tube end, and like this repeatable operation just can make the metal tube of required reducing.As shown in Figure 2: reducing mould 4 is some cover reducing moulds that internal diameter successively decreases.Use many cover reducing moulds the metal tube end can be dwindled step by step, metal tube is ruptured because of a reducing puts in place.This processing method also can be carried out reducing processing to two terminations of metal tube as required.
Fig. 3 has provided and has used the multiple metal tube through reducing that the present invention processes.Adopt circular, square, polygonal reducing mould, can be made into the metal tube reducing of different shape.As long as carrying out reducing, the mould of replacing respective shapes just can.
Claims (3)
1, a kind of diameter reducing working method for metal pipe; Comprise: metal tube is cut into required specification, carries out reducing processing, it is characterized in that: metal tube is fixed in the clamping device, is furnished with the reducing mould on the forcing press, described reducing mould is some cover reducing moulds that internal diameter successively decreases;
The operating pressure machine is suppressed the metal tube end, when the metal tube caliber does not reach necessary requirement, adopt and a preceding corresponding reducing mould of reducing metal tube caliber, the operating pressure machine is suppressed once more to the metal tube end, like this repeatable operation makes the metal tube of required reducing;
Under the squeezing action of mould, choke forms thicker metal parietal layer, makes metal tube add man-hour carrying out car system, the choke phenomenon of rupture can not occur.
