Description

Manual curved end face machine

Technical field

The utility model relates to a kind of flange equipment, especially relates to a kind of manual curved end face machine that tube end face forms flange or flange that is used for.

Background technology

In actual applications, for the ease of the dismounting of tubing and satisfy bonding strength and sealing requirements, often need the end face of tubing is carried out flanging, described flange can be directly uses (flange that will 2 tubing to be connected directly weld or be shaped on bolt hole connect with bolt get final product) as flange, also can be used (movable flange is enclosed within on the tubing and is pressed against and welds on flange pipe nipple one side) with the movable flange of loop type.Existing flange equipment respectively has characteristics.The mode that can realize 90 ° of angles of end face (flange) flange of tubing in the prior art generally has several schemes: 1. make spill die shoe and convex upper bolster, form the flange mouth by punch ram, but carry the length of pipe end to be subjected to punch press work Stroke Control (several centimetres approximately～tens centimetres); 2. by numerically controlled lathe or the moulding of engine lathe process spinning flange; 3. be soldered directly on the pipe end by prefabricated (flange) flange in advance; 4. earlier the port of tubing is expanded to 30～50 ° of angles by bordering tool or flaring tool, then 90 ° of right angle extrusion heads is against the extension mouth limit, the end face mouth is turned at an angle of 90 by electronic compression tool or hand-operated tools.The basic delivery tube that has flange mouth (flange) is because of being subjected to the restriction of instrument, and length can only be about tens centimetres.

The structural shape that in the past adopted the flange loose flange type is to be inserted in the loose flange type dish by the flange pipe nipple that punch ram forms the flange mouth, and spot welding is connected on the pipe end, remakes peripheral full weld moulding.But have following shortcoming: the commissure is generally single-sided welding, and inside and outside wall can't two-sides forming, and the quality welding is unreliable; Must be skilled work post, the cost height; Product connects and must carry out at the construction field (site), generally to carry out the operations such as cutting, welding, removing welding slag, pickling, passivation and preservative treatment of pipeline, often above-mentioned technological requirement can't be satisfied substantially in the job site, will begin corrosion from weld bond from now on, and the weld bond of welding easily gets rusty.The scene does not generally possess pipeline solder joint test of flaw detection equipment, if poor welding quality then under the discharge pressure stream mode, can cause tubing and flange to come off.

Publication number is that the application for a patent for invention of CN1792490 discloses a kind of apparatus for turnup of pipe, comprise in the seat groove of Fixing clamp-seat, frame, Fixing clamp-seat stationary slip and movable slips are housed, groove seat one side is equipped with the riser that has two leading screws, and two leading screws are replaced movable slips.Be fixedly connected with down power rifle slips on the frame, last power rifle slips and following power rifle slips are hinged, and the minor axis that is rotationally connected below the following watt of otic placode is fixed a clamping screw on the minor axis, and power rifle slips tightens by clamping screw, wing nut up and down.Driving gear shaft is fixed on the frame by its axle sleeve, driven gear shaft is installed on up and down in the power rifle slips by its axle sleeve, driving and driven gears engaged, adorn drill bit on the driven gear, dress up the type drift in the power rifle and change drill bit and pack in the power rifle slips, can realize the drill bit processing tube orifice again usable power rifle moulding drift make the pipe flange.

Publication number is the flanging device that the application for a patent for invention of CN1788875 discloses a kind of thin metallic tubd pipe tap, it comprises cutter arrangement and drive unit, the cutter head of described cutter arrangement is a plurality of and circumferentially evenly distributes along the axis of handle of a knife, described cutter head is divided into the elastic portion of fixedlying connected with handle of a knife and is arranged on the flange sword of elastic portion end, described cutter body is provided with tie rod hole along axis, and being equipped with in the described tie rod hole can be with the flange sword along the open pull bar of elastic portion; The flange sword remains on free state under the effect of elastic portion, cutterhead is inserted at an easy rate to be treated in the flange hole; After cutterhead is inserted into and treats in the flange hole, the pull bar pulling, the flange sword opens, and whole then cutter rotation is withdrawed from, and promptly finishes the flanging work of bore edges; Internal mold has been cancelled in this invention, has broken through the complicated technology that adopts eccentric flange cutter, and operating efficiency improves greatly; Especially a kind of technical scheme that realizes automated production.

Notification number is disposed with spindle lock, spinning aggressive device, workpiece control positioner, main shaft control device, variable-speed dynamic drive unit for the utility model of CN2799122 provides a kind of nothing centering rotary extrusion flanger on main shaft; Be provided with work holder in the support front; With spinning aggressive device correspondence position be provided with turn up spinning apparatus and in turn over spinning apparatus.

Summary of the invention
