Abstract
The method for reducing metal tube includes the following steps: cutting metal tube to required size, fixing the metal tube in holding device, operating pressing machine equipped with reducing die correspondent to the tube diameter of metal tube to press end portion of the metal tube. By adopting die pressing, under the action of extrusion of die the reducing portion can be formed into thicker metal wall, so that said reducing portion does not break when the metal tube is turned. Its working quality is good, working speed is high and working machine is simple in structure.
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: with metal tube Be cut into required specification, metal tube 1 is fixed in the clamping device 2, forcing press adopts Hydraulic press is loaded onto and the corresponding necking die 4 of metal tube caliber at hydraulic press cylinder 3, Hydraulic press can be selected according to the concrete condition of metal tube. 5 pairs of metal tube ends of operation hydraulic press Suppress. Under the squeezing action of mould, choke forms thicker metal parietal layer 6, So that metal tube is carried out car when processed, the choke phenomenon of rupture can not appear.
Fig. 2 has provided metal tube necking process of the present invention. When need carry out metal tube 1 During further reducing, hydraulic press is changed and the corresponding necking die 4 of a front reducing metal tube, The operation hydraulic press is suppressed again to metal tube end, and operation just can make so repeatedly The metal tube of required reducing. As shown in Figure 2: necking die 4 is some covers that internal diameter successively decreases Necking die. Use many cover necking dies metal tube end can be dwindled step by step, can not make Metal tube ruptures because a reducing puts in place. This processing method also can be as required to metal tube Reducing processing is carried out in two terminations.
Fig. 3 has provided and has used the various metals pipe through reducing that the present invention processes. Adopt circle Shape, square, polygonal necking die can be made into the metal tube necking of various shapes. Only The mould of changing corresponding shape carries out reducing just can.
