Abstract
The utility model relates to a sewer which comprises a sewer pipe; a continuously circular outer flange is formed on the upper end of the sewer pipe by punching. The sewer pipe is made of a seamed pipe; the angle between the outer flange and a plane is between 0 degree and 25 degrees. The sewer is shaped by punching the outer flange with the seamed pipe; the outer flange is in a continuously circular shape, does not crack, and has high material utilization rate. The sewer has the advantages of simple and reasonable structure, easy processing, low material consumption, low cost and high production efficiency, and is applicable to mass production and marketing.
Description
Technical field
The utility model relates to a kind of outlet device, particularly a kind of outlet device that adopts the stamping forming band flanging of seamed pipe.
Background technology
The outlet device body of existing outlet device and flanging are generally by welding or die cast, cost cost height.Disclose a kind of dewatering device processing technology among the Chinese patent literature CN101100032A, comprise the following steps: a, pipe cutting: steel pipe is slit into the satisfactory body that anhydrates of length; B, the draw: the body that anhydrates is installed on the corresponding reducing die, an end is wherein carried out reducing; C, blanking: steel plate is placed on the mould, described steel plate is washed into the body flange of ring-type; Step in the d, car: body flange is fixed on the lathe, at the medium pore interior step of getting on the bus out; E, welding: the body other end that anhydrates is pressed on step place on the body flange blank, both are welded into a whole; F, shaping: the spinner semiproduct are placed on carry out shaping in the shaping mould; G, machining screw: the body that anhydrates is carried out screw thread processing; H, processing side opening: the spinner body sidewall is processed to form side opening; Circular arc in i, the processing: the body inside of anhydrating of body flange one side is carried out circular arc processing, formed a sphere.The spinner production stage of this structure is many, and stock utilization is low, cost cost height, does not utilize and produces in batches and marketing.
The utility model content
The purpose of this utility model aim to provide a kind of simple and reasonable, production and processing easily, outlet device that the cost cost is low, to overcome weak point of the prior art.
A kind of outlet device by this purpose design comprises the outlet device body, and its architectural feature is the flanging that the upper end punching press of outlet device body is formed with continuous circular shape.
The tube wall of described outlet device body is provided with screw thread and/or side opening; In be welded with valve seat.Valve seat and outlet device inboard wall of tube body adopt inferior arc-welding welding, and outlet device body deflection is little, do not cause the flanging cracking.
Described flanging and horizontal plane angle are 0 °～25 °, and width is 5～20mm.The moulding of flanging is generally finished by three punching presses, and punching press for the first time makes outlet device body upper end rout up 60 °～75 ° flanging; Punching press for the second time, make just the flanging of one-step forming turn to outward with horizontal plane at 45～60 ° of angles; Last punching press, the flanging angle reaches pre-provisioning request.
Described outlet device body is that seamed pipe is made, and pipe thickness is 0.5～2mm.
Outlet device of the present utility model is by seamed pipe punching press flanging aftershaping, and flanging is continuous annular, do not ftracture, and the stock utilization height.It is simple and reasonable, handling ease, consumptive material is little, cost is low, production efficiency is high, is fit to produce in enormous quantities and marketing.
