Abstract
The invention provides a welding-free medium-low pressure flange with a sleeve, wherein the inner hole of the flange is shaped like a dentiform trapezoid; and the external diameter of the sleeve is in matching connection with the inner hole of the flange. In the prior art, when a flange needs to be configured with a sleeve, the general way is weld the flange and the sleeve by both sides after processing the flange and the sleeve, and carry out end surface finishing on a turning machine after welding; and such a process can cause material waste (sufficient allowance for end surface finishing is ensured) and low efficiency, and has higher requirements on operating staff ( otherwise, problems such as insufficient welding and poor perpendicularity between the flange and the sleeve can be caused). The welding-free medium-low pressure flange with the sleeve aims to solve the problem that the processing costs and the material costs of some medium-low pressure flanges stay at a high level. The flange provided by the invention is convenient to use, can reduce the cost (a 5 yuan cost can be saved on a flange with the diameter of 120 cm), achieves high efficiency and has low technical requirements on operating staff.
Description
Technical field
The present invention relates to a kind of flange, particularly relate to a kind of mesolow flange with well without the need to welding.
Background technique
Now domestic many enterprises, particularly some heavy industry enterprises (as shipyard etc.) can use many flanges, for easy to use and some special manufacturing technique requirents, need flange sleeve one section of sleeve pipe, and demand is very large, common way carries out two-sided welding after processing flange and sleeve pipe in the past, goes up the process that lathe carries out end face again after having welded.Such technique can cause the waste of material (end face processing must put enough surpluses), inefficiency, and to the requirement of operator higher problems such as (otherwise) perpendicularity of rosin joint and flange and sleeve pipe can be caused bad.Flange (flange that particularly batch is large) for some mesolows can form processing cost and cost of material remains high.
Summary of the invention
For the deficiency of above-mentioned technology, the invention provides one by place restriction, simple to operate, efficiently energy-conservation again device.
Without the need to a mesolow flange with well for welding, the endoporus of described flange is the trapezoidal of band dentation, and the external diameter of described sleeve pipe is connected with flange endoporus is identical, described flange surrounding symmetrical be no less than 4 exit orifice.
Beneficial effect of the present invention is, first, this device is easy to use, and reduce costs (cost-saved 5 yuan of the flange measuring and calculating of diameter 120cm), efficiency is high, not high to the technical requirements of operator.

Fig. 2 is the sectional drawing of endoporus;
Fig. 3 is the plan view of flange;

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
A kind of mesolow flange with well without the need to welding, the endoporus 2 of described flange is for being with the trapezoidal of dentation, as shown in figures 1 and 3, the external diameter of described sleeve pipe (as shown in Figure 4 and Figure 5) coincide with flange endoporus 2 and is connected, endoporus as shown in Figure 2, described flange surrounding symmetrical be no less than 4 exit orifice 1.
Simply introduce the principle without the need to the mesolow flange with well of welding and assembly process, flange, after the complete profile of machined into, during processing endoporus 2, finally uses forming cutter time processing.During the external diameter of same processing sleeve pipe, the size of bushing head also can process at one time.The flange processed and sleeve pipe are put into the last impact briquetting of punch press.Endoporus 2 due to flange is designed to be with the trapezoidal of dentation, is first conducive to guiding, has a function of rectifying a deviation during impact briquetting, and to ensure the perpendicularity of flange and sleeve pipe, secondly this being designed with is beneficial to all tooth occlusions, to increase the area of contact.From properties of materials, flange and sleeve pipe adopt A3 material, its yield strength is 200-230Mpa, specific elongation can reach more than 20%, consider simultaneously stressed after can produce certain plastic deformation, as long as so certain stamping press just can ensure the interference fit of profile of tooth, simultaneously commaterial makes flange and sleeve pipe be bonded together owing to producing plastic deformation, is ensured the sealing of junction by the bonding of parts of tooth and interference fit.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
Claims (2)
1. without the need to a mesolow flange with well for welding, it is characterized in that, the endoporus of described flange is the trapezoidal of band dentation, and the external diameter of described sleeve pipe coincide with flange endoporus and is connected.
2. flange as claimed in claim 1, is characterized in that, described flange surrounding symmetrical be no less than 4 exit orifice.
