Abstract
The utility model relates to an improved forming device for flatting a pipe and is composed of the mold tool of an upper concave groove, the mold tool of a lower concave groove, etc. When the pipe is flatted to be formed one time, a concave sagged surface doesn't appear in the middle of the pipe. The improved forming device for flatting a pipe can be used for the flatting and forming of the pipes within the range of the 25-57 millimeter phi and 2-3.5 millimeter wall thickness.
Description
A kind of pipe flattens shaped device, belongs to metal processing and flattens the pipe mechanical device.
In the metal current machined, the flattening moulding of pipe is on hydraulic press, and adopting upper and lower is the mould of groove, and pipe is flattened moulding.The sunken face of spill appears in the flat tube after the moulding in the centre like this, does not often reach the specification requirement (see figure 1) of drawing.
The purpose of this utility model provides the improved pipe of a kind of mould and flattens shaped device.Promptly the bottom portion of groove of upper and lower mould is processed into that the garden arcuate die realizes.On hydraulic press, adopt above-mentioned mould like this, just can make pipe once flatten moulding, and the sunken face of spill does not appear in the centre.The middle spill of flat tube that has overcome original device compacting falls into the harmful effect that brings in the face of velocity in pipes, can meet the specification requirement of drawing well.
Concrete structure of the present utility model is provided by Fig. 2, and this device is made up of the mould (1) of upper groove and the mould (2) of low groove etc.The groove floor of the mould of upper and lower groove is processed into circular arc, and the circular arc camber is between 0.5 to 0.8 millimeter.When pipe (3) is placed between upper groove mould (1) and the low groove mould (2), because the bottom surface Jia Gong Cheng Round arc of mould, make the contact-making surface of pipe and die bottom surface change, just the stressing conditions of pipe in the flattening process changes, and pipe middle spill that can not occur after flattening moulding falls into face like this.
Device of the present utility model is applicable to 25～57 millimeters of ∮, the flattening moulding of the pipe in 2～3.5 millimeters scopes of wall thickness.Flat tube as in the ammonia convertor single tube parallel type internals utilizes this device, and the flat tube after the one-shot forming can meet the specification requirement of drawing well.
Claims (1)
- A kind of pipe flattens shaped device, it is characterized in that flatting apparatus is made up of the mould (1) of upper groove and the mould (2) of low groove, and circular arc all is processed in the bottom surface of the groove of its upper and lower mould.
